# Chapter 237: Immortal-Sealing Six Seals
Shortly after arriving safely at Source City, Old Knife Handle silently vanished without a trace.
Li Desheng did not leave. The people of Yaoguang Holy Land strongly urged him to stay, and the women of Yao Chi also extended an invitation. The Yin Nether Eye could hardly be cultivated; it was an innate gift, extremely rare in the world, allowing one to see what ordinary people could not. Every major force would try to recruit such a person.
In the afternoon, Ye Fan rested briefly, then walked out of his room. Just then, Li Desheng also pushed open his door. The two shared a quiet, secluded courtyard.
In the courtyard stood a cluster of artificial rockeries, with spring water gurgling from above. Beside them was a grape trellis, hung with clusters of fruit like purple agates, the green leaves casting a patch of cool shade.
Under the trellis were a stone table and stone chairs for resting and enjoying the cool air. The faint fragrance of clear tea drifted. The two sat in the shade of the grapevines and chatted casually.
"Daoist, your Source Art is truly remarkable. Such skill is astonishing—you can venture into any dangerous land in the world." Li Desheng's face was full of longing.
"Forget it. This time was pure luck. In the Primordial Forbidden Zone, aside from the Great Emperor, anyone who enters by mistake means death." Ye Fan was telling the truth. If the Fourth Generation Ancestor hadn't carved a path of life in the pine forest, and if Eternal Universe Great Emperor hadn't already broken the Fallen Sun Ridge, they would have certainly died.
There were definitely other demon lands they hadn't seen. If they entered again and landed in an unknown, unfamiliar region, disaster would be certain—let alone the true ancient mine itself.
"Daoist, how did you cultivate such Source Art?" Li Desheng was very envious.
"Oh? Are you interested too?" Ye Fan's lips curled slightly, revealing a faint smile.
Li Desheng nodded. "I'm quite eager. If I could learn even a fragment, I'd do anything."
"This is nothing. I'll teach you a few tricks later."
"Can you really teach me?"
"You have a natural gift. The Yin Nether Eye is rare throughout history. Searching for sources and locking dragon veins mostly happens underground, and your unique power is very much needed."
"Daoist, please take me as your disciple!" Li Desheng was slightly excited.
"Forget about taking disciples. We've shared hardships. Teaching you a few techniques is no problem at all. Which sect are you from?" Ye Fan took a sip of clear tea and asked.
The Yin Nether Eye was naturally suited for this trade. When he went searching for sources and locking dragon veins in the future, having someone like this to help would certainly double the results with half the effort.
Li Desheng wanted to learn Source Art, and Ye Fan wanted free labor. The more they talked, the more they saw eye to eye.
"When this matter is settled, I'll come find you when I have free time!" Finally, Ye Fan stood up with a smile.
The people of Yao Chi were resting here and didn't plan to leave. They would return to the outskirts of the Primordial Forbidden Zone.
Ye Fan learned that Yao Chi had found an abandoned mine at the edge of the Primordial Forbidden Zone and was transporting some strange stone materials. They would continue this work.
In the evening, Ye Fan met the Holy Maiden of Yao Chi and learned more details.
"Fairy, why are you excavating an abandoned mine? What's so special about those stone materials?"
"Daoist, you are proficient in Source Art. You must have heard of the theory of suppressing sources." The Holy Maiden of Yao Chi stood by the rockery, bathed in the golden-red holy light of the sunset.
"Naturally, I know of it. Are you saying you need to seal some source stones?" Ye Fan's heart stirred.
Not all excavated stone materials were cut open. Some sects stored them. But as time passed, after leaving the source vein, the stone skin would slowly peel off.
At that point, people would usually peel off the stone skin and extract the source. However, there were special times when people didn't want the source inside the skin to see the light of day and would find ways to seal the source. Naturally, these were strange sources.
From past experience, the oldest stone skins from the Primordial Forbidden Zone were the first choice—the best material for resealing sources.
"What kind of source requires you to reseal it? The art of suppressing sources is rarely used." Ye Fan was puzzled.
If the stone skin was about to peel off, why not just extract the source directly? Why reseal it?
"These are a batch of stone materials left by predecessors. The matter is of great importance and cannot be cut open casually. This time, we have invited Source Art experts from all over the world to find a solution—how to seal them safely." The Holy Maiden of Yao Chi replied, her misty figure standing by the rockery like an orchid in an empty valley.
"Is the suppressing source art ineffective?" Ye Fan was surprised.
Yao Chi's Holy Maiden shook her head slightly, her voice like heavenly music. "The effect is very poor. It can only provide a temporary solution."
"What kind of source is this, that even the suppressing source art can't seal it? This is too strange." Suddenly, Ye Fan thought of the nine stone materials Yao Chi had exhibited. One of them, upon careful sensing, seemed like a sea of blood. Another contained a demonic power.
Ye Fan felt a chill. These were just two pieces from that batch of stone materials, most likely the most ordinary ones. What would the central stone material be like?
He pondered. That batch of stone materials probably had an extraordinary origin. Even going to Yao Chi Holy Land might not be entirely safe.
"The abandoned mines in the Primordial Forbidden Zone contain the oldest stone skins, the first choice for sealing materials. They shouldn't be ineffective, right?" He looked at the Holy Maiden of Yao Chi with doubt.
"Indeed, they are useless. We transported many strange stone materials from the edge of the Primordial Forbidden Zone, but none could seal them." The Holy Maiden of Yao Chi shook her head.
"How can this be..." Ye Fan frowned. Such stone materials were definitely beyond imagination.
"In the past, a senior left these stone materials and said that if a day came when sealing was needed, perhaps only the six ancient stone skins from the Primordial Forbidden Zone would suffice. But so far, we have only found two."
"What?" Ye Fan was startled. He thought of a possibility—the legendary "Immortal-Sealing Six Seals." This was a supreme Source Art that required six types of divine source stone skins as materials. It was a technique close to the Dao, capable not only of sealing sources but also mountains, rivers, and even peerless experts.
The Source Heaven Scroll recorded the "Immortal-Sealing Six Seals," but only in a few brief, extremely obscure sentences that were hard to comprehend. The scroll contained annotations stating that this was a theoretical Source Art, not necessarily achievable.
"Fairy, may I ask what the origin of those stone materials is?" Ye Fan was very surprised and puzzled.
"Actually, telling you is fine. Those stone materials were left by a Source Art expert with unparalleled skill." The Holy Maiden of Yao Chi replied.
Ye Fan's heart jumped. He immediately thought of one person—Zhang, the Fifth Generation Source Heaven Master!
In the past, this Source Heaven Master had an extraordinary relationship with Yao Chi. The Holy Maiden of Yao Chi at that time was his confidante. He was a distinguished guest of Yao Chi, and legend even said he was honored as an external Dharma Protector by Yao Chi.
The Source Heaven Master represented the ultimate realm of Source Art. The stone materials left by such a figure were unimaginable.
"There are seven stone materials in total. Three were left by that extraordinary person..." The Holy Maiden of Yao Chi narrated slowly.
Indeed, they were left by the extraordinary person Zhang. The nine strange stones Yao Chi exhibited were merely the peeling stone skins from one of those materials.
Ye Fan frowned. The origin of the nine stone materials was too great. It made him draw in a cold breath.
The stone material exhibited that day weighed two thousand jin, yet it was just the stone skin of one material, not the main stone. How massive must that main stone be?
He didn't speak, just listened quietly. He would soon enter Yao Chi, and he needed to understand these matters clearly.
Zhang was a man full of legends. He traveled through ancient mountains and deep lands, exploring countless forbidden regions.
He spent his life searching for sources and collected many stone materials. Among them, three were uncertain. Even in his old age, he couldn't determine what was inside and never cut them open. In the end, he handed them over to Yao Chi.
"Aren't there seven stone materials in total? What about the other four?" Ye Fan asked.
"The other four have mysterious origins. They were found by successive Holy Mothers. They are very special, even more ancient than the three. Unfortunately, no records were left."
Zhang had marveled at those four stone materials because their stone skins had once peeled off and were sealed by a technique similar to the "Immortal-Sealing Six Seals," but it absolutely couldn't be the "Immortal-Sealing Six Seals."
"Aside from the Source Heaven Master lineage, are there others who understand the deepest Source Art?" Ye Fan had doubts but couldn't voice them.
"Senior Zhang studied them for several months and praised them greatly, saying that all methods are interconnected." The Holy Maiden of Yao Chi said this.
The four stone materials were ancient, excavated by people tens of thousands of years ago. They had all been sealed and later obtained by Yao Chi's Holy Mothers. This was the conclusion of the Zhang family's first ancestor.
"Those stone materials are probably not good stones. Ancient materials sealed by means like the 'Immortal-Sealing Six Seals' must have a terrifying origin. I think these seven stone materials together are like a dangerous land. How dare you keep them in Yao Chi?"
"Those stone materials are indeed quite terrifying. If not for the suppression of an Extreme Weapon, we would find it hard to feel at ease." The Holy Maiden of Yao Chi replied.
"Why not find a way to cut them open? What's the use of keeping them?" Ye Fan was puzzled. With Yao Chi's foundation, breaking them open shouldn't be a problem.
"Because Yao Chi hasn't yet produced the right person. It's a matter of fate..." The Holy Maiden of Yao Chi didn't finish.
Ye Fan knew that Zhang must have seen something and given guidance. He became even more curious, wanting to see what was so extraordinary about those ancient materials.
"By finding some special bloodlines and combining them with powerful Source Art, if Yao Chi produces a suitable person, the stone materials can be cut open."
On the verge of entering Yao Chi, Ye Fan learned these details, which were very helpful to him. Finally, the Holy Maiden of Yao Chi left without mentioning the Phoenix Blood Red Gold.
The night was hazy, and the courtyard was especially quiet and peaceful.
It was already time for lamps to be lit. Source City was ablaze with lights.
"Ah..." Screams came, so sudden.
"Ah!" "Ah!"...
The screams came one after another, very fast, like a demon blade continuously killing, impossibly swift.
"What's happening?" The courtyard was thrown into chaos.
After all, the people of Yaoguang Holy Land and Yao Chi Holy Land were staying here. Who would dare to kill?
"Something's wrong! An elder has been killed..."
Shouts came from the Yaoguang Holy Land courtyard, with constant yelling and cries.
From initial reports, over a dozen people had already died. Ye Fan was startled. What was going on?
"Not good. Although they haven't targeted Yao Chi, something is very wrong. Could it be for the Phoenix Blood Red Gold?" Ye Fan's heart sank.
Like a ghost, he rushed out of the courtyard and melted into the darkness.
Almost instantly, he saw a tall figure with gray hair reaching the ground silently enter his room.
"An unknown creature? That shouldn't be..."
"Ah..." Screams came from time to time. Yao Chi's disciples were also attacked.
