Chapter 355: Sibling Bonds
No Money to Cultivate Immortality?
Facing Zhang Pianpian’s inquiry, Zhang Yu glanced at the Dao Seed glowing faintly on her chest, then at Yu Xinghan, who was happily chatting with Li Xiao. He sent a private message:
"Don’t worry, Senior Sister. I don’t need the money right now anyway. Take it."
Zhang Pianpian felt a strange stir in her heart. When she’d helped this boy back then, it had only been on a whim—he seemed talented, that was all.
Who would’ve guessed that he’d rise so quickly? Not only was he now her classmate at Wanfa Sect University, he could even offer her this many spirit coins.
Especially that reply of his:
"Don’t need it right now, take it…"
Who says things like that? What kind of normal person says something so outrageous?
And yet, for some reason, hearing those crazy words filled Zhang Pianpian with a feeling she’d never experienced before.
She nodded slightly and looked at Zhang Yu seriously.
"Alright. Lend me 25 spirit coins. I’ll pay you back—six months at the earliest, a year at the latest."
Zhang Yu replied,
"Is 25 spirit coins enough? I can lend you 50 if you need it."
He thought to himself:
"After all these months of testing and idle chatter, the Dao Seed has always asked for 50 spirit coins. That requirement hasn’t changed."
"Looks like it really does need exactly 50."
Zhang Yu had always been deeply aware of his sister’s strength.
Especially since arriving at Wanfa Sect University—seeing her tamper with dormitory mana consumption data, then watching her in the underground tomb disable networks, hijack surveillance, and toy with people’s Law Husks.
Now, with the Dao Seed’s price tag—50 spirit coins for the Supreme Purity Sigil—Zhang Yu was convinced Zhang Pianpian’s Dao Seed had to be incredibly powerful.
"Well then… Supreme Purity Sigil! Activate!"
…
On the other side, Zhang Pianpian blinked in surprise when she received Zhang Yu’s message.
Fifty was obviously better than twenty-five… but the guy only had 56 coins total. Giving away this much in one go…
As she was still hesitating, she saw the transfer come through.
50 spirit coins.
Zhang Pianpian:
"Are you insane?"
"Who the hell just sends
this much money without a second thought?" She looked at Zhang Yu like he was the dumbest person in Kunxu.
Because in Kunxu, giving away money like this? That was beyond stupid.
Money meant potential. It meant power, it meant a future. It meant life.
Lending 50 spirit coins all at once was the same as lending someone your life—it was giving them your future potential.
But since Zhang Yu had already made up his mind to lend her the full amount and activate her Dao Seed, he didn’t intend to drag things out.
"No point beating around the bush."
So he replied:
"Senior Sister, just take it."
"I know you're strapped for cash."
"And the stronger you get, the better you can protect me."
Looking at Zhang Yu, Zhang Pianpian’s heart swelled. Her younger brother had just handed her nearly all his spirit coins.
She’d seen mountains of money before. But right now, not even ten thousand spirit coins could compare to the fifty she’d just received from Zhang Yu.
"This… is what it means to be family?"
Silently, she accepted the transfer.
Zhang Pianpian felt as if a warm current flowed from his body into hers.
That warmth was his potential. His life. His future.
And now… he was giving it all to her.
"Little brother, I’ve felt your strength. I understand your heart."
"I won’t waste any of it…"
Right after Zhang Pianpian accepted the money, Zhang Yu received a digital contract from her.
He blinked in surprise as he read it:
"A repayment contract? Starting next month, pay me back 5 spirit coins per month… for 12 months?"
Zhang Pianpian:
"I’ve accepted the money. And for what I need to do now, the more I have, the better."
"Sign the contract."
Zhang Pianpian:
"You lent me this money, I’ll pay it back—with interest. That’s how we honor our bond."
In her heart, she thought:
"You were willing to lend me this money. I’m willing to repay you with interest. That’s what makes us true family. This repayment contract—that’s the bond between us."
Zhang Yu didn’t know what kind of "bond" Zhang Pianpian was thinking about, but since she insisted, he signed the contract.
As the agreement finalized, Zhang Pianpian could feel their sibling connection deepen.
Zhang Yu, on the other hand, watched her curiously, eager to see how this Supreme Purity Sigil Dao Seed would activate.
But all he saw was Zhang Pianpian close her eyes—her consciousness diving into the Spiritual Realm.
Moments later, when she opened her eyes again, the Dao Seed silently lit up.
Supreme Purity Sigil (Sigil) – Level 1
Zhang Yu thought:
"It worked?"
Just then, Yu Xinghan tugged his sleeve.
"Come on, what are you standing around for? Class is starting!"
"First lecture of sophomore year—we can’t be late."
No time to test the Sigil’s effect in detail, Zhang Yu followed Yu Xinghan and Li Xiao to class.
…
Classroom.
When Zhang Yu entered, he saw that the seat dead center in the front row had been left open.
Ying Xin waved him over.
"Senior Brother! Over here!"
Seeing her so eager, Zhang Yu thought,
"As expected of the sixth-generation civil engineering prodigy—adapts quickly. Must run in the family."
He sat down with Yu Xinghan on his left.
Li Xiao tried to sit on Zhang Yu’s right, but Ying Xin bumped him aside.
"I have something to talk to Senior Brother about. You go sit somewhere else."
Seated beside him, Ying Xin pulled out a pillbox and offered it to Zhang Yu.
"I went to your dorm last night, but you weren’t in. So I figured I’d give this to you in class."
Zhang Yu took the box and casually opened the lid—expecting to see a standard stamina pill.
Instead, he froze.
"Wheat flour?!"
"You’re seriously giving me this in the classroom?!"
But a moment later, it clicked.
"Wait—is this the ancestral bone ash Ying Xin mentioned? Why’s it so white?"
Fu Ji’s voice echoed in his mind:
"That just means it’s high quality—burned cleanly, maybe contains some metal elements. And the person it came from was probably Foundation Establishment Realm at least."
Realizing it wasn’t flour but bone ash, Zhang Yu let out a breath of relief.
Fu Ji added,
"She put it in a pill bottle on purpose—to avoid attracting attention. Not bad. She’s got real civil engineering talent."
Watching him open the bottle, Ying Xin explained:
"It’s from my great-grandfather. A few drops of blood and a sprinkle of this into your concrete—massive structural boost."
"You’re definitely entering this year’s civil engineering competition, right? You’ll need it."
Zhang Yu weighed the bottle in his hand and smiled.
"Thanks, Ying. I appreciate the gesture."
Ying Xin smiled back. Zhang Yu was now Director Gao’s named disciple—if she got close to him, she’d be connected to Gao as well.
Inwardly, she thought:
"Great-grandpa, now that you're in Zhang Yu's hands, please bless me. Let me rise under Director Gao and become a true queen of the construction site."
Just then, their instructor arrived.
He stepped up to the podium and got right to the point.
"My name is Wei Huai. I’ll be teaching your Engineering Geology course."
"Starting sophomore year, civil engineering students will learn construction-based techniques."
"And to fully master these, you’ll need to understand terrain and site geology—only then can you draw out a technique’s full potential..."
Seated in class, Zhang Yu began multitasking with Limitless Heart: Inner Incarnate Body—half his mind on the lecture, the other diving into the Dao Seed Codex via Feathered Tome to study the Supreme Purity Sigil’s effects.
"Wait—raising it to level two needs another 100 spirit coins?!"
"My sister’s talent really is a money pit…"
As he focused, more information surfaced from the Dao Seed.
"The Sigil’s core function… is to create a Spiritual Realm dwelling?"
Zhang Yu’s curiosity flared. He wanted to dive in and see this Spiritual Realm dwelling for himself.
But he remembered his sister’s warning—do not activate Limitless Heart: Inner Incarnate Body while entering the Spiritual Realm.
Without it, he couldn’t multitask.
"And I can’t afford to skip class."
"I’ll check it out later when I’m free."
He continued listening to the lecture, gradually gaining a sense of how large-scale construction techniques interacted with various terrains and landforms.
The whole day passed with Zhang Yu focused on his classes. That night, back in his dorm, he finally stopped using Limitless Heart: Inner Incarnate Body and put on his Spiritual Realm Mask.
As he activated the Supreme Purity Sigil, his consciousness shot through the Spiritual Realm—passing flashes of radiant color in rapid succession.
When he came to, he stood before a mist-shrouded Daoist temple nestled in the mountains.
Looking at the characters above the gate, he murmured,
"Supreme Purity Domain?"
He stepped inside. The place wasn’t big—just one main hall. Inside, Zhang Pianpian sat cross-legged before an immense, faceless statue.
As Zhang Yu entered, Zhang Pianpian suddenly turned, shocked to see him at the door.
But then her eyes narrowed, a glint of killing intent rising.
"Zhang Yu can’t be here," she thought.
"Someone dares impersonate my brother and sneak into the Supreme Purity Domain?!"
She formed a hand seal. Instantly, the world trembled.
Zhang Yu felt an immense force crash into him—like his body was about to shatter into pieces.
Before he could even react, his ID, browsing history, bank records, and transaction logs flowed from his body like discarded data fragments, hovering in the air.
Zhang Pianpian’s eyes widened in shock.
"Zhang Yu? It’s really you?"
"How did you get into the Supreme Purity Domain?"
