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

"Could I take a look at the 'Supreme Forgetfulness Technique'?"

Faced with Lin Wuhua's request, Xie Jiexue hesitated for a long time before finally agreeing.

Even though she didn't want him to see the "Supreme Forgetfulness Manual".

She told Lin Wuhua about the Lake of the Heart, the ice surface, and the stalactites in a calm tone, as if she were talking about something that had nothing to do with her.

After speaking, Xie Jiexue tapped the ground with her toes, looking at Lin Wuhua, worried that he might say something.

But to her relief, Lin Wuhua didn't say anything after reading "The Supreme Forgetfulness Manual," he just shook his head.

"...I see, I see."

His gaze frightened Xie Jiexue, but she didn't say a word.

......

After Xie Jiexue left, Lin Wuhua didn't say anything more and continued doing his own thing.

He simply studied the books in the library quietly and quietly increased the proportion of time he spent guiding others.

He gave guidance to everyone who asked, and he did so even more frequently.

After Bai Wu returned from the middle of the book-filled area, he asked him, "Wuhua, how are you?"

Lin Wuhua replied, "I have read the 'Supreme Forgetfulness Manual'."

Bai Wushu: "How does it feel?"

"I don't feel anything," Lin Wuhua opened the book, pursed her lips, "Intercepting snow is too painful, so she can only cultivate this."

"I don't blame her; it's not her fault."

"—However, I think there has never been a 'way' in the world that is worth such a sacrifice."

Lin Wuhua continued to study, guide, and practice, and he practiced even more diligently.

His physical condition, which had been slightly improving, began to decline, and the cough returned.

Some people who didn't understand him asked him, "Wuhua, can't you rest for a while? Your body can't take it like this."

Lin Wuhua would always cough and refuse.

"No, rest won't help me."

Whenever he said this, he would always look at the summit of the Sword Sect.

Even after that day, Xie Jiexue never came again.

And so, Lin Wuhua's body visibly deteriorated.

He became increasingly silent and quiet, but remained steadfast.

On one occasion, Lin Wuhua coughed up blood again in front of Bai Wushu.

Bai Wushu couldn't help but advise him, "Why bother?"

This time, Lin Wuhua wiped the corner of his mouth and answered.

"Master, what do you mean by 'once bitten by a snake, twice shy'? What are you afraid of?"

Bai Wushu was taken aback: "Afraid of snakes?"

Lin Wuhua shook his head: "No, it's because I'm afraid of the pain, the slippery coldness of the snake, and the feeling of being bitten."

"Not everyone is afraid of snakes, and not everyone will be bitten by a snake, but everyone is afraid of pain; that's human nature."

"So, I don't blame her; it's my responsibility."

Bai Wushu understood this time.

"Couldn't you have tried to persuade her?"

"No," Lin Wuhua closed her eyes, "because I can't convince her that it won't hurt this way."

After that, Lin Wuhua started doing something strange.

He started asking his peers, including Xie Jiexue, what kind of person they thought Xie Jiexue was.

The disciple who greeted them when they entered the sect, Jiang Shouzhou, who had already reached the rank of elder due to his military achievements, answered him.

"Sword Master... When Jie Xue first arrived, she wasn't very talkative."

"Back then, she went to the training ground a lot, but after each sword practice, she wouldn't leave. Instead, she would sit in the pavilion for a while."

"Once, I saw her holding half a sesame seed cake, but she didn't eat it. She just held it there while looking at the library."

"I didn't dare ask at the time, but she stayed for a long time before leaving, and she stayed like that for many days afterward."

"I think she was probably waiting for you, thinking about whether she should go and talk to you about it."

"But a few days later, you started practicing swordsmanship with her, and she stopped standing there. I figured she probably told you about it, so I didn't think much of it."

Finally, Jiang Shouzhou replied, "Actually, she only smiles at you."

Lin Wuhua remained silent for a long time, then sincerely thanked him and took his leave.

He returned to his room and closed his eyes.

He had already developed his own ideas about the second level of the Heart Sword a few days ago.

Seeing one's true nature—from the self to others.

The anger, fear, and desire of practitioners are not unique to all people.

Based on self-awareness, one can see the commonalities between oneself and others within oneself.

A scene appeared in Lin Wuhua's mind.

Fifteen-year-old Xie Jiexue, cold and hungry, huddled in a dilapidated temple in the wind and snow, gazing at him from afar by the fire.

He reached out to her and saved her.

It was a simple favor, and naturally, he became the only light in her dark life.

Later, he gave her a name, dignity, and warmth.

Later, in order to save her, he implanted his sword bone into her body.

Lin Wuhua suddenly remembered that Xie Jiexue had always been cold and aloof since joining the sect, and didn't like to talk to people.

Is this really entirely due to factors related to sword bone and martial arts techniques?

Among the disciples of the Sword Sect, few are poor and many are rich, but she was not only once poor, but was even saved by Lin Wuhua.

Under such circumstances, how could she possibly be willing to trust and be close to others?

As for Lin Wuhua...

In the real world, he is mature and no longer believes in any hierarchical system.

Moreover, even in the simulation, he was almost a former top student, invincible in his studies, but he gave it up for the sake of the Sword Sect.

There's a difference between being able to do something but not doing it, and never doing it at all.

He continued to think, and then that sentence came to mind:

"Raising you is worse than raising livestock. It's more worthwhile to marry you off and exchange you for some money."

Those were the words Xie Jiexue's parents said to her, a fifteen-year-old girl with no means of livelihood.

What will she think? How scared must she be? Will she have nightmares? Will she cry at night?

Under such circumstances, this girl met Lin Wuhua, who gave her almost everything she deserved.

If Lin Wuhua were Xie Jiexue, and such a benefactor sacrificed his future and life to save her, what would he do?

Is this a debt that can be repaid?

If Lin Wuhua dies...

Lin Wuhua opened his eyes and began to cough violently.

He understood; this was enlightenment.

Understand your own heart, and you will see the nature of others.

From the self to the other, from "my pain" to "human pain", from "my fear" to "human fear".

Fear of pain, fear of loss, yearning for connection, forced strength due to vulnerability, and voluntarily humbled out of love...

This is human nature.

Lin Wuhua pushed open the door, walked out of the Sutra Repository, and gazed at the summit of Sword Sect Mountain.

The Supreme Frost is a perfect sword; perhaps only a perfect heart can wield it.

Lin Wuhua was certain of this.

After a long time, Lin Wuhua went back.

not enough.

He needs the complete Heart Sword, a Heart Sword powerful enough to change everything.
