# Chapter 841: Divine Calculator and the Taboos of Heaven and Earth
The mountainous terrain undulated, with thousands of peaks standing tall, forming a natural Eight Trigram pattern imprinted on the ground, magnificent in scope.
Stone mountains dominated the landscape, with occasional ancient trees taking root among the rocky crevices, appearing even more verdant. One or two orchids filled the valley with their pure fragrance, creating an atmosphere of profound tranquility.
The group traveled dozens of li deep into the mountains, none daring to be careless. The Divine Calculator was considered a remarkable figure of his generation, and his secluded dwelling was extremely strange—anyone who mistakenly entered his mystical formations might become lost.
The celestial mechanism was unclear, shrouded in chaos. This was the result of the Old Blind Man's several divinations using tortoise shells—he could discern nothing, as if they were in a place before heaven and earth had separated.
"That grave-robbing thief didn't come. If he had, we could have let him dig tunnels, and with my knowledge guiding us, the path would have been unimpeded all the way," Black Emperor said.
After advancing more than a hundred li, fog began to rise, and it was very thick—within a few meters, no one could be seen. It was eerily strange, with the mountains utterly silent, not a single sound.
Among them, it wasn't just Ye Fan who had cultivated the Heavenly Eye Penetration. Black Emperor's third vertical eye could also open and gaze hundreds of li into the distance, but now it could not pierce through.
The gray mist had risen very strangely, as if they were walking on the Yellow Springs Road, step by step approaching the Nine Netherworlds, about to push open a forbidden door.
"I feel like we're walking to our deaths, step by step heading toward the Netherworld," Li Tian said.
"Yes, it's like walking down a road of no return, about to open the gates of hell," Yan Yixi also had this illusion.
Ahead, there was no road. A door appeared, waiting for people to push it open. Cold air rushed into everyone's pores, chilling their bodies.
"A door has really appeared?" The Old Blind Man's heart sank. He tried divination again, but the result was the same—fruitless.
"This is an ancient formation, obscuring the celestial mechanism," the Big Black Dog said, baring its teeth. It felt it had met its match and began to study it carefully.
"Open your Divine Maiden Furnace. The weapon of a human clan Great Sage can isolate the celestial mechanism," the Old Blind Man said, unconvinced. He told Yan Yixi to take out the furnace and perform the divination inside.
The Sacred Furnace was unadorned, simple and natural, but with a slight activation, it became crystalline, transforming the ordinary into brilliance. The tortoise shell fell, crackling with sound, and finally produced a hexagram.
"The path ahead is an omen of great misfortune!" The Old Blind Man frowned.
"This is no simple matter. This person is proficient in array patterns and well-versed in ancient methods. He's a worthy opponent," the Big Black Dog said, its expression turning serious.
"It's not just about array patterns. He can truly calculate and divine—he already knows we've come," the Old Blind Man said.
There were countless ancient and modern array patterns, but too few who grasped their essence. The Divine Calculator was undoubtedly a pinnacle figure, miraculous in his arts, capable of shifting heaven and changing earth.
"We've met our match!" The Big Black Dog bared its teeth and forcefully pushed open the door ahead, as if opening the Netherworld's soil. Various wailing sounds came from ahead.
"Everything is illusory. Don't worry, everyone. Watch how I break it," the Big Black Dog said, throwing in various formation flags and necessary formation-breaking materials like Phoenix Earth and Star Stone, changing the formation's configuration.
After a long wait, the door disappeared. Ahead, the area opened up, and even the mist thinned, revealing a stone forest.
"With me on the job, there's no formation I can't break," Black Emperor boasted shamelessly.
"Be careful. He can deduce the celestial mechanism and knows more than just this," Ye Fan reminded, warning it not to get carried away.
The Big Black Dog acted arrogantly, swaggering in with its head held high, saying, "When I handle things, you can rest assured."
The others exchanged glances. Could this dog be trusted? With its attitude, would following it in cause any problems?
"Woof, woof, woof!"
In an instant, the Big Black Dog, which had entered the stone forest, had all its black fur standing on end, as if struck by lightning, and fled out.
"Damn it, woof! Haunted!" The Big Black Dog fled for its life, its bald tail held high—if a flag were hung on it, it would become a flagpole.
"Clatter, clatter..."
Iron chains rattled violently. A disheveled old woman rushed from deep within the stone forest, her limbs pierced by chains as she chased Black Emperor. Her white hair flew backward, her expression ferocious.
"Owww..." Black Emperor screamed in agony. Its bald tail was caught and bitten by the old woman, and all its dog fur bristled upright.
"Boom!"
Seeing this, Ye Fan acted immediately, offering the Vajra Ring. It transformed into the size of a millstone, shining with silver light, breaking through the heavens and crashing into the old woman.
"Clatter, clatter!"
The chains rattled incessantly. The old woman was sent flying, crashing deep into the stone forest. Her body did not break in two, and she let out a low roar.
Black Emperor fled in terror, all its black fur standing on end. "Scared me to death! Where did she suddenly pop out from?"
The others were speechless. This bastard had brought it upon himself. He had been so confident and boastful just moments ago, only to be chased out with his tail between his legs.
"Damn it! I've been bitten by a human!" After calming down slightly, Black Emperor immediately jumped up, furious. "How many tens of thousands of years has it been? No one has dared to bite me!"
This was indeed true. Usually, it was the one doing the biting. Even when Ye Fan first met him, he had been bitten by the dog many times, once harboring immense resentment.
"Why don't you bite her back?"
"Jumping heavens! I've been bitten by a ghost. Am I supposed to go bite a ghost?" Black Emperor was quite indignant, then said, "Wrong specialty. We should call that fat grave-robbing thief. This is his area of expertise."
Li Tian muttered, "I thought the saying was 'Just treat it like being bitten by a dog—would you go bite the dog back?' That should be the saying, right?"
"What do you mean?" The Big Black Dog bared its teeth and gave Li Tian a bite with a grunt.
"Damn it, why are you biting me? That old woman is waiting for you to bite her!"
"Stop messing around. We've entered the Divine Calculator's trap. This isn't a stone forest at all—it's an underground cave," the Old Blind Man said.
Ye Fan's heart tightened. He observed carefully with his Heavenly Eye, then sucked in a breath of cold air. The array patterns were so miraculous that even the Heavenly Eye Penetration could be deceived. This was absolutely an unparalleled divine formation.
Without realizing it, they had entered an underground world. It was a cave, dark and gloomy. Ahead was a stone chamber where an old woman, like a vengeful ghost, was bound by iron chains, constantly struggling, trying to charge at them.
"I've been tricked. The formation-breaking earlier was real, but after taking one step, we were teleported underground. The surrounding illusions fooled us," Black Emperor said.
"This is an ancient corpse. In life, it was incredibly powerful. It has turned into a ghost soldier, imprisoned here by someone. This mountain region is truly extraordinary," the Old Blind Man said.
"The teleportation platform is in the old woman's stone chamber. That's the only life gate of the ancient formation. We have to kill her to escape the underground world," Black Emperor said.
"Leave it to me," Yan Yixi said, holding the Divine Maiden Furnace. With a gentle shake, the ancient Great Sage's weapon slowly awakened, then emitted a wisp of firelight.
"Boom!"
This old woman had been a Greatly Accomplished King in life. After turning into a ghost soldier, her flesh had become indestructible to a terrifying degree, but under the Divine Maiden Furnace, she was instantly reduced to ashes.
Back on the surface, the heavy mist remained, gray and hazy. The sky was completely invisible, as if they had arrived in the Netherworld.
"I'll focus with all my strength this time. I guarantee no mistakes," Black Emperor said.
They weren't too worried, after all, they had the Divine Maiden Furnace in hand. The weapon forged by the Eternal Universe Great Emperor for the founder of the Path of Human Desire was, if not the strongest below Imperial weapons, then close to it.
"Oh, not simple. Chaotic qi is swirling here. This place is almost becoming a primordial land," the Old Blind Man said.
"It's a convergence point of dragon veins," Ye Fan thought, then said, "Let me lead the way." He walked forward, and Source Heaven Dao patterns flickered beneath his feet. The earth itself seemed to shift, constantly moving, decomposing various array patterns.
Black Emperor watched in stunned amazement. "Kid, you're impressive! Being able to break divine formations like this—I must borrow the Source Heaven Scroll to read."
"Have you reached the level of an Origin Heavenly Master?" the Old Blind Man asked in surprise.
"There's still a way to go. And even reaching that level isn't the end. I've seen the Source Art of the founder of the Source Art Aristocratic Clan. It absolutely transcends the Origin Heavenly Master level. At that level, Source Art has become Dao principles, comparable to Saints."
At this moment, Ye Fan transformed the mountains and earthly veins. The great mountains rumbled loudly, constantly shifting, opening a great path. The scene was astonishing.
Only at the end did he stop, not daring to act rashly. The array patterns ahead were too profound. He was not yet an Origin Heavenly Master and dared not move recklessly.
"Heavens! This is... a corner of a Great Emperor's array pattern. The Divine Calculator knows so much!" Black Emperor was shocked. He pondered for a long time before acting.
This time, the Big Black Dog went all out, directly carving a corner of the Primordial Slaughter Formation, attacking fiercely to break through the dense Dao patterns.
In this stone mountain range, the aura of an ancient Great Emperor permeated the air, rising with endless killing energy, sweeping through the nine heavens.
"This is difficult. This old man knows so much. He's used various famous ancient formations to complement each other, maximizing the power of this corner of the Great Emperor's array pattern."
The Big Black Dog, wearing a large floral shorts, stood upright. One big paw hugged its chest, while the other continuously stroked its chin, thinking for a long time.
"Boom!"
However, at that moment, the ancient array patterns ahead suddenly disappeared. Two great mountains moved apart, revealing a broad, sunlit road. All the mist in the mountains vanished.
"Oh? Giving up defense? Surrendering?" Black Emperor was suspicious, afraid of a trap.
At the end of the road, a pair of children timidly approached, speaking softly, "Please stop attacking. Our master invites you in."
They were a boy and a girl, both about eleven or twelve years old, wearing Daoist robes, with red lips and white teeth, very beautiful. They possessed a natural spiritual aura, not like ordinary people, more like Dao children from the Immortal Realm.
"These two people..." The Old Blind Man was immediately shocked, almost rushing over to embrace the two children, which frightened the jade-like Dao children into retreating.
"What's wrong?" Ye Fan asked.
"They are a pair of spirit children, born specifically for deducing the celestial mechanism. They appear once in thousands or hundreds of generations. These two children are born together, and even if they leak celestial secrets, they have methods to resist the tribulation," the Old Blind Man said excitedly.
The boy and girl were beautiful and pure, like siblings, as their eyebrows and eyes were very similar. Upon hearing this, they both stepped back, looking a bit scared.
"Our master invites you in," they said softly.
Ahead, there were no magnificent palaces or grand caves. This was a pure and peaceful land, with beautiful scenery.
Flowing springs and cascading waterfalls, green vines and vines, small bridges over flowing water, pavilions and small chambers—everything returned to nature.
Deep in a bamboo forest stood several thatched cottages, returning to simplicity. It seemed like a paradise beyond the mortal world, making people ponder and stare blankly.
In front of the thatched cottage, an old Daoist with white hair and beard sat on a cushion. Seeing the group arrive, he stood up and said, "Honored guests have come. Forgive me for not welcoming you from afar."
This was absolutely a remarkable figure of his generation, possessing an immortal aura, untouched by worldly affairs, as if he didn't belong to this mortal realm. The group had come to demand an accounting, but now they all surprisingly calmed down.
The Divine Calculator invited them to sit, recited a Daoist title, and said, "I know why you have come."
"Of course you know. Your lineage has schemed against us countless times. Now it's time to settle accounts," the Big Black Dog said.
"The person you're looking for is the father of these two children. He passed away two years ago," the old Daoist sighed.
Behind him, the beautiful little siblings with red lips and white teeth immediately had red eyes. They wiped their tears with their wide Daoist robes, looking timid and pitiful.
Years ago, one of the Divine Calculator's outstanding disciples had calculated everything about Ye Fan. If Pang Bo hadn't returned the God-Slaying Whip in time to conceal his aura, he would have been caught by the Yin Yang Sect.
"Who are you trying to fool? What a coincidence," Black Emperor didn't believe it.
"I do not speak falsely. In this world, there are some things that cannot be deduced, some celestial secrets that cannot be revealed. Otherwise, heavenly punishment will surely come," the Divine Calculator said gloomily.
The Old Blind Man nodded. He was a person in this field and naturally knew the various taboos involved.
"I am also about to face tribulation. Probably after you leave, a great calamity will descend upon this place. I have been cautious all my life, but in the end, I have leaked some heavenly secrets, said things I shouldn't have said. I am about to face my retribution. These two children can inherit my legacy. You may take them away. Please treat them well."
Ye Fan and the others were stunned. They hadn't expected to hear the Divine Calculator arranging his final affairs upon arriving here, contrary to their original intentions.
At this moment, they all felt a sense of reverence. This was absolutely a remarkable figure of his generation. Setting aside his cultivation, his various methods of deducing the celestial mechanism were probably unparalleled through the ages.
"Master, don't abandon us. Father has already left... wuwuwu..." The two children cried loudly.
The Divine Calculator had taught over a dozen disciples, and almost none had met a good end. Only two or three were still alive, but their situations were also precarious.
"It's my fault. I only looked at their talent and didn't pay attention to their temperament. None of them could strictly discipline themselves. They calculated the celestial mechanism but couldn't keep it to themselves. They spoke of it, and finally, disaster befell them all," the Divine Calculator said, transcendent and detached. When tears rolled down his face, it felt especially strange and moving.
The father of these two children was his youngest disciple, with extremely high talent and aptitude. Because he had received great kindness from the Yin Yang Sect, he had calculated everything about Ye Fan over a decade ago to help them.
"Calculating a person shouldn't lead to heavenly punishment. He just passed away like that?" the Old Blind Man asked.
"Naturally, deducing a person wouldn't be a problem. It was because he calculated a forbidden domain that he met with disaster," the Divine Calculator sighed.
"The ancestor of the Northern Domain Source King lineage was one step away from becoming the sixth Origin Heavenly Master in history. But in his later years, misfortune befell him. Two years ago, one late night, various wailing sounds and ghostly cries echoed through their clan. That ancestor disappeared. My father was invited to help with the deduction, and on that night... wuwuwu..." The two children cried as they spoke.
"Origin Heavenly Master..." Ye Fan's heart shook. This curse was hard to break. After so many years, even someone one step away from reaching that level had encountered misfortune in their later years. His heart was greatly stirred!
"In this world, there are truly some words that cannot be spoken carelessly, or great disaster will strike," the Divine Calculator said, deeply grieved.
"Did your outstanding disciple deduce the various secrets of the Origin Heavenly Master's later years?"
"And what celestial secrets have you leaked that will bring such great tribulation?"
Everyone was very eager.
"I couldn't bear the loneliness and deduced the secrets of the ancient Great Emperors. Naturally, this brought great disaster," the Divine Calculator said.
"Boom!"
As soon as he finished speaking, a thunderous roar echoed through heaven and earth. A massive bolt of lightning descended from the sky, destroying the thatched cottage. A bottomless black hole appeared in its place, extremely terrifying.
The two children cried loudly, trembling like frightened fawns, holding each other, pitiful and helpless.
"See? My great calamity is approaching. I will face my retribution at any moment," the Divine Calculator said with a smile, as if he had seen through everything in the world, looking up at the boundless sky.
