Chapter 170

"I remember Nahida was born from the purest branch broken off by Greater Lord Rukkhadevata."

"But in the new world, Greater Lord Rukkhadevata still exists; how could Nahida possibly appear?"

Su Bai turned and looked at Lumine.

He said calmly, "Nahida is one I created, to accompany Buer."

Chapter 100: You've taken quite a few detours, but thank you for all your hard work up to now.

Su Bai gazed at Buer and Nahida, hand in hand.

"According to the timeline, the scenes of the new world I saw were from the same period as when I was in the old Sumeru."

Based on Su Bai's explanation,

Lumine finally understood everything.

The new Teyvat covered the old Teyvat.

Lumine, residing in the old Teyvat world, could not feel the five hundred years of life in the new Teyvat.

It seemed like the blink of an eye, yet in reality, it had already been five hundred years.

The concept of time did not exist at that moment.

As for why Nahida and Paimon could not see the fusion of the new world, the reason was that they were both part of the World Tree.

Their information did not contain the ability to perceive changes in the World Tree's data.

Just as Greater Lord Rukkhadevata erased her own information.

Nahida and Paimon felt as if they had experienced nothing; suddenly, all information regarding Greater Lord Rukkhadevata was erased from their minds.

"During this period, you kept trying to control Nahida's dreams and consciousness."

"The main purpose was to collect all information about her, and to meet her..."

"First, to trick her into coming to the World Tree to eliminate Greater Lord Rukkhadevata; second, to communicate with her and personally feel her true situation."

"Hmm..." Su Bai nodded, unable to deny it.

"To modify the information on the World Tree, one must eliminate the forbidden knowledge on the World Tree; Buer's existence would hinder my plans."

"And the only one who can eliminate her is her own reincarnation, Nahida."

"Nahida was unaware that she had repeated the same thing in her dreams for hundreds of years."

"It was just that the kindness in her heart prevented her from making other judgments, and I was somewhat displeased with this."

When Su Bai opened his heart, he smiled awkwardly.

"Her character is too weak; as a god, being bullied by her subjects is simply unacceptable."

"So I could only meet with her and give her a good beating."

"As for creating her, it was not difficult."

"Copy the information she left on the World Tree after being beaten last time, and a new Nahida can be produced."

"Having her serve as Buer's subordinate in the new world is quite good."

"After all, she looks exactly like the five-hundred-year-old Buer; Buer will like her."

Lumine propped her chin up, lost in thought.

Overall, judging by the situation, the Su Bai before her was not a villain; rather, he seemed like a savior changing Teyvat.

Along the way, Lumine had met her brother, Aether.

Although she did not understand what the other party truly wanted to do, while exploring the Shenyuan Sect together with Dai Yin, she had understood some things.

The catastrophe of Khaenri'ah brought indelible disaster to both the people of Khaenri'ah and all of humanity in Teyvat.

Just as the scenes of the new world she saw now showed, if the catastrophe of Khaenri'ah had not occurred in Teyvat, the happiness index would have risen by several levels.

"As you said, the most difficult point in modifying the World Tree's information lies in the progression of time."

"The further back in history, the more energy is consumed and the more severe the side effects borne."

"You also need to modify the will of the One-Eyed Sage Ilmin and the Golden Rhinedottir."

"Plus creating Nahida..."

"Then, what about Buer?"

"Her memories were slightly altered by me; only her memories of me personally were erased, so she did not need to bear too much pressure." Speaking here, Su Bai sighed, a hint of bitterness appearing on his face.

"My consciousness cannot bear history any further back."

"Sigh, although I very much want her to remember me, I cannot bear it; with her character, she would definitely spend a vast amount of time and energy searching for someone deeply buried in memory who does not exist."

"I think this is not good..."

Su Bai paused, looking at Lumine awkwardly: "Hahaha, actually, my heart is also quite uncomfortable; after all, no one wants the person they love deeply to forget them, right..."

"I also want to stay by her side, but..."

Su Bai shrugged: "Unfortunately, the reality does not allow it. I am not a person of Teyvat; even if I could create someone similar to me, the power seems insufficient..."

Live broadcast room.

Nilou: "This... did Mr. Su Bai voluntarily erase Buer's memories..."

Alhaitham: "I finally understand the entire process. Moving history backward consumes the most power; next is changing the will of major characters. As for the creation of Lesser Lord Kusanali, since the World Tree has the final information backup record, directly copying it does not consume too much energy."

Cyno: "To maintain the efficiency of power usage, they could not go back to the day when Grand Sage Su Bai met Greater Lord Rukkhadevata, so they had to forcibly erase Greater Lord Rukkhadevata's memories."

Dvalin: "I don't understand at all; I just know that in the new world, me and Barbatos seem very carefree."

Venti: "Ah, don't say it as if the two of us have no proper work to do."

Klee: "But why did Mr. Su Bai say that erasing Greater Lord Rukkhadevata's memories did not consume much power? And why is there such a huge difference when modifying will?"

Zhong Li: "Because he merely erased Greater Lord Rukkhadevata's memories of himself. For Greater Lord Rukkhadevata herself, her various information did not undergo huge changes. However, modifying will completely changes everything about a person; personality, behavior, and so on, will all undergo huge deviations due to changes in consciousness and will, leading to huge changes in the entire person, so the consumption is massive."

Dottore: "The simplest way to create a person in the World Tree is to train them in the real world into the desired form, then copy them out. Unfortunately, Grand Sage Su Bai is not a person of Teyvat; the World Tree has no record of him. Even if he wanted to copy, he would have no way to do so. Recalibrating new information would require power that is hard to imagine."

Tianquan Ningguang: "Sigh, what a pity. If Grand Sage Su Bai's power were a bit more sufficient..."

Neuvillette: "He has already created an entirely new Teyvat World, forcibly altering Teyvat while the overall world continues to function normally. If Great Sage Su Bai's power were any stronger, who knows what would happen."

Furina: "I believe the reason Su Bai did not inscribe himself has nothing to do with power consumption. First, inscribing himself was not the purpose of this time. Second, he never belonged to Teyvat to begin with. The person inscribed on the World Tree is not the real him. That is why Nahida came to be, because Nahida is still the Nahida of Teyvat who yearns for Buer. Su Bai used his remaining power to maintain his consciousness just to see Buer one last time."

Abyssal: "I agree with the Hydro Archon. This is very Su Ye."

Kamisato Ayaka: "Alas, it is a pity that Mr. Su Bai can only leave his consciousness within the World Tree, quietly watching for a while. He is right before our eyes yet untouchable; this feeling somehow feels even more unbearable."

Yae Miko: "What is even more regrettable is that everything Su Bai did was merely a change for a single lifetime. When the time comes, it will cycle back again."

Zhong Li: "The authority on the Sky Island is the key control hub for the entire World Tree. Alas..."

Abyssal: "Uh, it feels like Su Ye gains something with each cycle. Last time, he failed to save Furina due to issues with authority; this time, he went to acquire authority. But unfortunately, there is still the Sky Island above."

Lisa: "So his final cycle was truly, as the opening preview suggested, that he boarded the island."

Jean: "Alas, so his final cycle was his final farewell to Lumine?"

Lumine: "Hey, don't speak so harshly. What do you mean 'final farewell'? We are very good right now."

【Considering everything together.】

【The conclusion Lumine finally reached was that the new world of Teyvat was wonderful, but the Su Bai before her had gained nothing.】

【Whether it was the Buer he saved, or his students...】

【No one would know that a person named Su Bai existed in this world.】

【Even if he returned to the new world to tell them everything, he might be deemed insane.】

【Lumine silently gazed at Su Bai's back.】

【He looked affectionately at Buer within the scene.】

【But from Lumine's perspective, Su Bai's back was so weathered and desolate.】

【Her heart trembled. Suddenly, a flash of inspiration struck Lumine.】

【"Do you need me to convey your longing for you?"】

【"I mean, if it were Buer, she would surely believe my words, because her consciousness has some connection with the World Tree."】

【"She surely understands the operating rules of the World Tree and Teyvat. I think she would understand."】

【Unfortunately, Su Bai shook his head and said, "No need. This would only add to her distress."】

【However, just at this moment...】

【An anomaly suddenly occurred.】

【"So, you drifted here from outside the world?"】

【"....."】

【Su Bai and Lumine were both stunned simultaneously.】
