What does it mean that they all lived with lifelong regrets?

in the real world.

Lin Wuhua clenched his fists and coughed violently.

"Researcher Wuhua, are you alright?"

The nurse rushed over immediately, looking at Lin Wuhua with concern.

"I......"

Before Lin Wuhua could finish speaking, he clutched his chest again.

"I'm fine...cough cough cough..."

He took the nurse's handkerchief, covered his mouth, and coughed forcefully.

It took him several minutes to calm down, and red bloodstains accumulated on the white handkerchief.

"Researcher Wuhua, why don't you take a break? I'll cancel your doctor's check-up later."

Lin Wuhua refused.

Only family members know their own affairs.

The cough had nothing to do with his physical condition; it was simply because the aftereffects of the broken sword bone in the simulation were too great.

Ultimately, Lin Wuhua wanted to sacrifice himself, but he didn't want to die completely.

Although the "Bone Removal and Transplantation Method" was required to shatter one's own sword bone and transplant it into Xie Jiexue's body, direct surgery was clearly not an option—otherwise, the simulated Lin Wuhua would die instantly.

Although his life wasn't that precious in the simulation, such a huge mission was still not finished.

He was sacrificing himself, not committing suicide.

Therefore, the specific process is as follows:

First, one must slowly and repeatedly injure Lin Wuhua's sword bone from outside the skin and flesh.

But we can't break it, at least we can't let him die.

Then, the essence within the sword bone was extracted in reverse through a secret method and transferred to Lin Wuhua's meridians, and then transplanted into Xie Jiexue's sword bone using the matching method in the "Bone Removal and Transplantation Method".

Finally, the remaining fragments of Lin Wuhua's sword bone were reconnected to maintain its structural function, thus ensuring Lin Wuhua's recovery.

This process requires Lin Wuhua's full cooperation and must be completed in one go.

You can imagine what that feels like.

The simulation does not involve the body, but extremely intense pain can cause a severe stress response at the physical level.

This was unavoidable, and the consequence is that Lin Wuhua is still coughing to this day.

He waved his hand: "It's a good thing to have the doctor examine me."

After a while, it was time for the researchers to conduct their inspection.

"What's wrong?" he asked as he walked over.

"I'm fine," Lin Wuhua said, "you can check it out for me."

The researcher, who was also a doctor, quickly examined it.

"Indeed, there's nothing wrong. It feels like I've been overusing my brain."

He glanced at the nurse and said, "Go tell your director that Wuhua researcher has overworked his brain and needs to rest for a few days."

The nurse left, leaving only Lin Wuhua and the researcher in the room.

Lin Wuhua: "Thank you."

The researcher shook his head: "No need, it's me who needs to rely on you."

He opened his briefcase and handed a file folder to Lin Wuhua: "There's a big client here."

Lin Wuhua glanced at it and raised an eyebrow.

Researcher: "Is it difficult?"

Lin Wuhua shook his head, then nodded.

It's certainly not simple, but on the contrary, it's all too familiar.

This is the orthodox sword manual of the Supreme Sword Sect, but only the first half is available, and most of the first half has been damaged.

"It's not simple," Lin Wuhua said. "I'm not very confident."

It wasn't that he lacked confidence, but rather that Lin Wuhua couldn't admit he was confident.

He looked up at the researcher who had tightened his grip.

This person seems a little nervous.

Lin Wuhua returned the sword manual, saying, "My head hurts a bit, I can't think straight."

The researcher's hand twitched, and he leaned forward slightly: "Is it difficult?"

Lin Wuhua shook his head: "I can't do it, I have a headache."

He raised his eyes and looked at the researcher, his gaze calm.

Meeting that gaze, the researcher felt a sudden tightness in his chest, and even a slight sense of panic.

Left with no other choice, he unleashed his trump card: "This came from Extraordinary University; it's from a long-time customer I've been trying to book."

Lin Wuhua's pupils contracted, and his hand tightened: "These are research questions from Extraordinary University. That student is applying for an experimental class or an elite class there."

"But all in all, it's fine, the main thing is that this matter is of great importance, so he offered a high price."

Lin Wuhua: "......."

His gaze made the researcher's heart grow heavier and heavier.

Finally, he nodded.

"Okay, but this information isn't enough. You need to give me more."

"Also," Lin Wuhua said, "tell me about what's going on inside Extraordinary University."

"Otherwise, I can't do it."

......

The researcher went outside.

He picked up the phone and took a deep breath.

"The head of the Shan family has agreed, but he needs more materials."

His steps quickened, and his hushed voice became even more urgent.

"But if you seek the master of the Shan family, your son may need to put in more effort."

"The manuscript by the Wuhua researcher is very clear, but it is absolutely unacceptable if he cannot understand it."

He paused, glanced at the door behind him, and shook his head.

"After this is over, you need to keep things clean."

......

the other side.

In the distant federal capital, the city has descended into chaos.

A violent ice storm swept through the city center, and blizzards, cold winds, and freezing temperatures completely enveloped the city, plunging the entire capital into a pale white expanse.

Intense spiritual energy, carrying a storm, swept through the city streets, uprooting everything exposed, including security cameras, air conditioner units, and lampposts.

Xie Jiexue opened her eyes and raised her hand to clench it.

The Supreme Frost appeared instantly in her hand.

"The beauty of nature..."

She covered her chest.

The sword bone trembled violently within Xie Jiexue's body, transmitting information to her.

Amidst this jumble of information, a distant connection stands out starkly.

This is information about the sword bone and its original owner.

After the last time the sword bone told her that its original owner was still in this world, it fell into silence.

But just now, a certain connection within Jian Gu's body weakened drastically, indicating something to Xie Jiexue.

The original owner of the sword bone was in a state of weakness, and the connection was about to break.

— Lin Wuhua is likely not doing well.

The door was pushed open.

It was Xie Jiexue's contact person, Xu Shuang.

"Sword Master—"

Xie Jiexue didn't want to listen at all.

Before Xu Shuang could say anything, a sword aura suddenly appeared out of thin air.

In the blink of an eye, Xu Shuang was turned into an ice sculpture.

Xie Jiexue ignored it.

Xu Shuang is not dead; this is just a warning.

If she doesn't do anything, they'll really think she's an easy person to get along with.

Xie Jiexue moved and disappeared from the spot.

When she reappeared, she was already high in the sky.

The sword stopped around her, and she hovered in the air, beginning to activate the sword bone.

"Tell me, where is your master...?"

"The beauty of nature..."

The sword bone within her body throbbed, constantly transmitting information to her.

Suddenly, Xie Jiexue opened his eyes, his gaze filled with extreme agitation.

A powerful aura greeted them, almost identical to Xie Jiexue's.

Xie Jiexue didn't know this person, only that he was also a reincarnator, but was employed by the local government and indulged in debauchery every day.

Perhaps it was because he always stared at Xie Jiexue with a strange look that she found him disgusting.
