# Chapter 664: An Unforgettable Farewell
The transformation only lasted a short while before Wang Gang deflated like a balloon and changed back!
Having exhausted all his spiritual energy, he almost collapsed to his knees!
Yet his face was still brimming with excitement, his eyes filled with gratitude as he looked at Jiangnan!
He had really become a Spirit Warrior. Everything felt like a dream!
Jiangnan was also quite shocked. He hadn't wasted those 30 Marrow Cleansing Fruits on Wang Gang. If this ability grew, his combat prowess would definitely be terrifying!
Wang Gang was emotionally stirred, grabbing Jiangnan's hand: "I really don't know how to thank you. Is there anything I can do for you?"
"As long as you say the word, Boss Nan, I'll go through fire and water..."
Jiangnan patted Wang Gang's shoulder and smiled brightly: "You don't need to do anything. Today you saved many people in the square. Consider this your reward!"
"If you really want to do something, then work hard to become stronger and protect more people. In this era, Spirit Warriors carry responsibility on their shoulders!"
"No matter how powerful you become in the future, I hope you'll always remember that impulse to step forward when you were in the square today!"
"The world needs more people like you!"
Wang Gang gritted his teeth, nodded heavily, and hot tears streamed uncontrollably from his eyes!
A tough man shedding tears!
No one knew how many days and nights Wang Gang had trained like crazy, his heart yearning to become stronger, to accomplish something!
Today, Jiangnan had given him a chance!
A brand new life!
Wang Gang's crying actually made Jiangnan a bit embarrassed!
He just didn't want to see such a talented person go to waste, so he gave him a helping hand!
Wang Gang reminded Jiangnan of his former self!
Since he was doing a good deed, he might as well see it through!
With a pained expression, Jiangnan pulled out 10 Diamond-grade Spirit Pearls from his alternate dimension and stuffed them into Wang Gang's hands!
"Keep these for training! They're a loan. Remember to pay me back when you're awesome, okay? With interest!"
"This is the contact info of Red Dragon, the Dragon Abyss Captain. If you want to join Dragon Abyss, find Red Dragon when your level is high enough. Tell him I sent you!"
Wang Gang was deeply moved. Just as he was about to speak, Jiangnan waved his hand and teleported away without a trace!
Looking at the direction Jiangnan had gone, Wang Gang gripped the spirit pearls tightly, bowed 90 degrees, tears dripping onto the ground!
"Boss Nan! Thank you! I'll remember!"
And Jiangnan had no idea what kind of miracle his unintentional action tonight would create...
With a heavy heart from losing 10 spirit pearls, Jiangnan returned to the apartment.
Xuexue and the others were already asleep. Jiangnan tiptoed into his room.
As soon as he entered, he found Xiao Mila sitting on the bed in her pajamas, drowsy and nodding off, with Xiao Jiuwo sleeping soundly in her arms.
(๐⁼̴～⁼̴๐)
When she saw Jiangnan return, her eyes instantly widened. She reached out her arms to him and said coquettishly, "Jiangnan Gege! Hold me to sleep~"
Jiangnan's heart melted. She stayed up this late just to wait for him to come home?
Could she be any sweeter!
He scooped up Xiao Mila, hugged her, and crawled into bed. Grinning, he said, "I'll grant you this little request tonight!"
"But you're already a grown-up. You can't always sleep with me. From now on, you have to sleep in your own room, got it?"
Mila smiled sweetly, hugging Jiangnan tightly: "Mhm, just tonight!"
After more than ten minutes, Mila looked up and asked in confusion, "Jiangnan Gege? Why aren't you sleeping yet?"
Jiangnan coughed lightly: "Your ribs are poking me a bit..."
Mila paused, then spiritual energy flowed through her body. Her young figure began to grow at a visible rate!
In the blink of an eye, she transformed into her 27-year-old appearance!
Golden hair cascaded down, her delicate features beautiful like an angel descended from heaven!
Her pajamas were stretched to the point of deformation as she blinked her big eyes at Jiangnan!
"What about this? Still poking?"
Jiangnan: Σ(๐ŏ口ŏ)
Who could withstand this?!
Mila! You should apologize to the pajamas! They're pitiful, you know?
"Quick! Change back!"
Mila: (•̌～•̑๐)ˀ̣ˀ̣
Seeing Jiangnan shut his eyes tightly, Mila quickly transformed back into her childhood form!
She became even more certain that Sister Nightingale was talking nonsense!
Jiangnan finally breathed a sigh of relief, deciding to sew Mila a pair of Hulk Brand Shorts when they returned to the academy!
That way, it would be more convenient for Mila to transform back and forth!
The next morning, Jiangnan and the others packed up to return to the academy!
But the dark circles under Jiangnan's eyes were quite prominent!
As soon as they stepped out, they saw 100 trainees lined up neatly downstairs. Many were holding flowers and small gifts!
They all had red eyes and reluctant expressions. The three Catgirl sisters were even wiping tears and sobbing!
Jiangnan smiled brightly: "Hey hey hey, isn't this a bit much? If I didn't know better, I'd think you came to send me off to a funeral instead of seeing me off!"
His words made many laugh, but then some trainees started crying even louder!
˚‧º·(˚˃̣̣̥᷄⌂˂̣̣̥᷅)‧º·˚
The 15 days of training had been fulfilling every single day!
They not only learned how to take a beating, but also learned coordination, combat techniques, and perseverance!
At the same time, they learned what responsibility and duty meant!
All the trainees could feel that Jiangnan was teaching them to become stronger in his own way!
Although a bit brutal, it made the deepest impression!
And that explosive final lesson!
From initial disapproval to wholehearted acceptance, then to admiration!
Everyone had grown so much!
Now that Jiangnan and the others were leaving, how could they bear to let go?
Wang Zhan cried out loudly: "Mentor! Beat us for another half month! We can take it!"
"Yeah! Don't leave! We beg you to hit us!"
Nightingale, who had come early to witness this scene at the academy, was stunned!
Jiangnan was probably the only one who could get his trainees to act like this!
Xing Da beside him turned pale. Another half month? You guys might be able to take it, but the academy's vault definitely couldn't!
Jiangnan grinned, teleported up, and gave Wang Zhan a sharp knock on the head: "Beat you my ass! If you keep crying, I'll beat you all to tears before I leave!"
The trainees' faces paled, and they promptly held back their tears!
Then Jiangnan patted Wang Zhan's shoulder: "The world is wonderful. You're all kids I've trained! Don't waste your abilities in the future, got it?"
The trainees replied in unison: "Yes, Mentor!"
One by one, they hugged and said their goodbyes!
Jiangnan even received a custom-made pennant!
The words "Demon Mentor" on the pennant were strikingly bold!
On the left was written "Heartless Jiang the Devil!"
On the right was "No regrets being your trainee!"
Jiangnan's face darkened.
Xia Yao snickered. The Demon Mentor pennant was truly fitting for Jiangnan!
Wang Zhan: "Boss Nan! Please accept it. It's everyone's heartfelt gift!"
Jiangnan: (▀Ĺ̯▀ꐦ)
"I've decided I'll beat you all to tears before I leave after all!"
"Boom!"
With a loud crash, Wang Zhan's body was sent flying!
[From...]
9 minutes and 27 seconds later!
Jiangnan patted his hands, accepted the pennant with satisfaction, collected generous teaching rewards from Uncle Da, and led Zhong Yingxue and the others away from Jingdu Spirit University!
Now this felt more like his way of saying goodbye!
The 100 trainees lay sprawled on the ground, faces bruised and swollen, tears streaming down!
Wuwuwu~
Boss Nan, somehow we don't feel so reluctant anymore!
...
Leaving Jingdu Spirit University, Jiangnan didn't fly directly back to the Pioneer Academy. Instead, he followed Nightingale to a café!
There were still some things about Mila that weren't clear!
In the café, Jiangnan casually set up a spatial barrier for soundproofing to prevent information leaks!
"That day you said Mila using large-scale innate spirit arts would consume her lifespan. What did you mean?"
Nightingale said solemnly: "You should remember the time reversal Mila used at Yulong Town!"
"Afterward, we examined Mila's cells and found that the telomerase inside had decreased!"
Jiangnan was taken aback!
Every time human cells divide, they consume telomerase. Basically, after about 56 divisions, the telomerase is used up, the cells lose their ability to divide, and then they die!
Because of Mila's Time System ability, the telomerase in her cells never decreases, allowing infinite division—hence the term "immortal cells"!
It was because of this property that the Immortal Serum was created!
Theoretically, Mila is immortal!
But using large-scale arts reduces the telomerase in Mila's cells?
"Doesn't Restoration work?"
Nightingale shook her head: "It's useless! So we suspect that large-scale innate arts like time reversal exceed what Mila's body can withstand!"
"It's the price she must pay for disturbing time. If she uses them without limit, once the telomerase in Mila's cells is completely depleted, she will die of old age!"
Jiangnan's heart sank: "What arts does Mila currently have?"
Nightingale said: "Excluding her natural healing constitution, there are four: Restoration, Time Stop, Dawn Blossoms at Nightfall, and Time Reversal!"
"The first two can be used. We tested them and they don't consume telomerase!"
Jiangnan asked curiously: "I've seen three. What kind of art is Dawn Blossoms at Nightfall? Does it also consume telomerase?"
Nightingale shuddered: "Flowers that bloom in the morning wither before dusk. You can imagine!"
"This is Mila's only offensive art so far, and it consumes a small amount of telomerase. Don't use it casually either!"
"When Mila's level is higher and her body strengthens, she might be able to use it freely. But for now, don't!"
Jiangnan hugged Mila and became serious for once: "Did you hear that? Only use the first two. Don't use the latter two recklessly, got it?"
Mila: "(๑◔‸◔ิ๑) Mhm! Mila will be good!"
Nightingale continued: "Mila's identity is sensitive. To the outside world, just claim she's a Healer-type Spirit Warrior. Restoration and Time Stop are enough to divert public attention!"
"The Pioneer Academy has already made arrangements for her enrollment. Since Mila is with you, I believe you'll protect her well!"
Jiangnan grinned: "Don't worry! No one can take away a treasure that's in my hands!"
