I might be a fake Ultraman.

The diary was stolen by Tokiwa Sougo and his gang.

Then they opened the diary and read the parts that Baili Yuan had skipped over.

They saw what Swartz had written about Bailiyuan's "massacre" of history.

"Zi-O erased humanity from the past because they had mastered the power of Agito..."

"Zi-O erased the alchemists from the past eras because they attempted to use alchemy to understand the truth..."

"The Time-O erased the magicians of the past because they were trying to develop more advanced magic..."

"Zi-O erased..."

In Swartz's diary, Baili Yuan is portrayed as a complete tyrant.

He indiscriminately carried out large-scale annihilation of anyone who dared to plot power, possessed potential, or perceived the truth, regardless of race or profession; it was undoubtedly a massacre.

Every line of text is accompanied by piles of white bones, and seems to exude a pungent smell of blood.

"Swartz, you dog, why do you write everything in your diary?"

"Wait, why didn't I realize what I was doing and blurted those things out?"

"You old fool, you must be the one spying on me too!"

"What exactly are you trying to do? My unity with Tokiwa Sougo is surely detrimental to your plans, isn't it? Could it be related to the enemy the old man is guarding against?"

Baili Yuan was initially annoyed, but then he seemed to have discovered the key point.

Bai Liyuan offered no explanation for the contents of the diary, and also abandoned any thought of comforting Tokiwa Sougo.

He wanted to see what the old devil was up to.

Does that mean the Bailiyuan massacre is history?

It can be said that he did indeed commit massacres.

But there's a reason for that!
Parallel worlds will eventually perish, and the parallel world where Baili Yuan is located is no exception, even though it was a parallel world that was personally separated by the old demon king.

That parallel world is still an illusion.

Once the main world's historical storyline concludes, regardless of whether the main world achieves the old demon king's goal, the parallel world will no longer have any reason to exist.

In order to give parallel worlds a future, Baili Yuan travels through the history of parallel worlds. On the surface, he is collecting Knight Watch heads, but in reality, he is like a gardener, diligently pruning away branches that should not exist in history.

Parallel worlds are direct copies of the main world. The main world is merging with other worlds, and parts related to other worlds are also being copied to parallel worlds.

Although these worlds merged into one, skipping the process of world fusion, the factors from other worlds that were inserted into the Zi-O world became unstable.

It can be understood as a "lost zone" that existed in the past, or some other possibility.

These unstable Lostbelts are factors that will lead the world to destruction and must be modified.

History is like a tree; only by pruning its branches can it grow strong and healthy.

The Sky Wall didn't suddenly appear in modern society, Shibuya wasn't destroyed by a meteorite, artificial intelligence didn't rebel, and more than a dozen political systems didn't emerge... These are all the results of Baili Yuan's hard work!
Moreover, Baili Yuan is not simply conquering a world, but turning a false world into reality, which is beyond his capabilities.

Only an existence like the King of Ultra could save a world on the verge of destruction single-handedly.

Baili Yuan's ability to turn the illusory into the real was entirely due to the absolute dominance of the Demon King in history.

Later, with the guidance and help of figures like Kurokami and Kouta Kuzuha, Hyakuri Enoki finally found the true way to save the parallel world.

Those branches pruned by Baili Yuan weren't actually destroyed; rather, they were integrated into history in a more rational way, and even projected into the future. But Swartz didn't see Baili Yuan's role in saving the world, nor did he understand his actions.

Even the truth cannot be spoken aloud by Baili Yuan.

If Baili Yuan, who is the Zi-O of the parallel world, reveals the truth of the parallel world, then all the truths will become reality, and there will be no possibility of saving the parallel world.

While it may seem that Baili Yuan is having fun in a parallel world, in reality, he is walking on thin ice even in that world.

Baili Yuan once again deeply empathized with the old demon king.

He could have salvaged his reputation by telling the truth, but he couldn't bring himself to speak it.

Baili Yuan: My script is like walking on thin ice. Do you think I can ever reach the other side?
Old Demon King: Hard to say.

Following this, Swartz also explains that he was able to perceive the reasons for these historical changes.

This is naturally because Swartz is a member of the Time Clan, possessing an extraordinary perception of changes and fluctuations in time.

That's why he was able to accurately spy on Baili Yuan.

"As a member of the Time Clan, are you really that sensitive to time? My secretive actions have already triggered your reaction?" Baili Yuan thought to himself.

Faced with questions from Tokiwa Sougo and the others, Hyakuri En maintained a smile and offered no explanation.

"Why did you do that?" Tokiwa Sougo asked, bewildered.

"Just do what you want. If you think they're in your way, then make them disappear~" Baili Yuan had an ambiguous smile on his face, and the sunny and cheerful boyish temperament of him became strange. He raised his hand and wiped his hair, slicking it back into a big slicked-back hairstyle.

Hairspray hands, start!

I must say, this is kind of interesting.

“Tokiwa Sougo, a person can’t even empathize with themselves a second ago, so how can you be sure that you can gain your approval in another world?” Baili Yuan said with a smile.

Tokiwa Sougo was greatly shocked and staggered backward, where he was supported by his Geiz and Tsukuyomi.

If the old demon king causes trouble in the future, then don't blame Baili Yuan for messing with his younger self in the modern world.

Black Woz patted the "Twilight Calendar" in his hand, his smile unchanged, but his words were anything but merciless.

"According to the records in my book, I regret to inform you that you are not the Demon King I recognize, Tokiwa Sougo of the other world."

Minako Miharu refused to believe that the group, which had been so close just moments before, had suddenly fallen apart.

"So, the idea that changing history can bring about a good ending is just a deception, isn't it?"

Parallel Gates and Parallel Tsukuyomi were even more devastated. They originally thought that Baili Yuan was not absolutely evil, but reality told them that Baili Yuan just did evil in front of them.

Bai Liyuan left alone, leaving his Geiz and Tsukuyomi to Tokiwa Sougo in the main world.

After all, having Parallel Gates and Parallel Tsukuyomi with him could easily lead to them encountering danger.

After Baili Yuan left, he returned directly to the other world.

"To tell you a story that nobody knows, I actually made a copy of Swartz's diary a long time ago."

Thus, another copy of Swartz's Diary appeared in Baili Yuan's hands.

"Then, let me see what Swartz's ultimate goal really is..." (End of Chapter)
