Spoilers for all the worlds

Fan Xian took a deep breath and looked at Su Han. If in a prehistoric world, offering sacrifices to heaven is equivalent to having the qualifications to become a saint... then it would be terrible.

After all, sacrificing to the heaven should be just a method of world protection that was randomly given by the chairman of the parliament and is common in all realms... Its main function is to protect the world, and all other functions are secondary functions.

Can even a minor function allow members of the parliament in a world like the prehistoric world to rise to the top in one fell swoop?

The scene was quiet, and many people frowned.

The expressions of those who knew about the prehistoric period were changing, while those who didn't know... had a look of deep astonishment and shock on their faces.

Su Han looked strange. He was also frightened by Fan Xian's bold guess.

He lowered his head slightly, stared at his palm, and used the divination technique. After divination several times in a row, he came to a specific conclusion and said concisely, "What you said... is feasible."

"Sacrificing sacrifices to heaven is indeed equivalent to gaining the qualification to become a saint! However, on the way to offering sacrifices to heaven... they will not participate in fighting off evil things. Therefore, they cannot obtain the merits of the prehistoric world!"

"...Is that so?" Huang Rong let out a long breath, not sure whether it was regret or something else.

"Li, is it possible to become a being of that level?" Li Jing's expression was extremely complicated.

He thought of Yuanshi Tianzun, feeling excited, confused, melancholy... countless emotions intertwined together. He was unable to use words to specifically describe his mood at the moment!

"But, there is no point in discussing this now." Conan reacted after a brief shock. He looked very serious. "Have you forgotten that in order to sacrifice to God, you must at least achieve unprecedented great achievements or become the strongest in the world?" By?"

Fan Xian's mouth opened slightly. After he realized what had happened, he was choked.

Become the strongest in a mythical world like the Devil Boy? Although this cannot be said to be impossible, the difficulty is definitely beyond imagination... Even if the ancient master is thrown into the world where the devil boy comes to the world, he may not be called invincible.

As for achieving unprecedented achievements... this is also very troublesome.

"Although it is possible to reach the sky in one step, is it extremely difficult?" Accelerator suddenly laughed, but his smile looked a little ferocious, "It is in line with the principle of equal exchange."

"This sentence... you are the only one who is not qualified to say it." Xiaoyu rolled her eyes, "Becoming a demon in your world is the real way to reach the sky in one step..."

"After all, before becoming the Demon God, the combat power was understandable. After becoming the Demon God... I can only describe it as incredible."

"Yes!" Illya nodded in agreement and whispered, "If it didn't feel inappropriate, and the chance of success in the end was very small... I would have wanted to go to Mr. Accelerator's world, and then find Index, let’s see if we can learn the catalog of forbidden books in her mind.”

As long as one learns the 13,000 forbidden books of magic and integrates them, it is possible to become a demon... Even if Ilia thinks about it now, her heart is still throbbing.

If she had this level of power, then...if she wanted to, she could erase all the tragedies in the world. By that time, even her father's dream... can still be expected to be realized, right?

Fate/zero has a great influence on Illya. Let her see the true side of her father...

Of course, more importantly, Illya also knew that Emiya Kiritsugu in her own world finally gave up his ideals for her and made a wish to let her become an ordinary child.

In essence, Illya was very moved. Therefore, she is also willing to work hard in the direction of her father's wishes...

"I think the situation is not that simple." Aizen narrowed his eyes slightly and his voice was indifferent.

"Mr. Aizen...do you have any new ideas?" Sakata Gintoki raised his eyebrows.

"You should know that I devoured Yhwach and gained part of his omniscience and omnipotence, right?" Aizen's voice was as calm as ever.

Members of Parliament, you look at me and I look at you. Finally Yuki Asuna spoke, and she was very honest, "I know that you devoured Yhwach, but I really didn't know that you gained the power of omniscience and omnipotence..."

Aizen's eyelids twitched a few times. Did he overestimate the IQ of these guys in the council? However, his eyes then passed over Tony Stark, Conan and others, and found that they were very calm and understood...

Are only smart people able to infer this from what he did before? That's fair to think about, after all, he hasn't said this directly in the past.

Thoughts flashed in his mind, Aizen's voice did not fluctuate, "After I gained the power of omniscience and omnipotence, I also traveled to other worlds. However, I found... Although I can use the power of omniscience and omnipotence in other worlds, the consumption will increase a lot."

"The power of the devil! It's too powerful and mysterious... I don't think this power can be used in all worlds. It is more likely that the power of the devil is limited to the world of the Magical Index..."

"This is unreasonable." Tang Hao said flatly, and he looked in the direction of Master Ancient One, "Didn't Master Ancient One say last time... Can the Parliament allow the abilities of different systems in different worlds to communicate with each other? That is to say, forced adaptation. "

"You didn't listen to me." Aizen said noncommittally, "I said before that my power of omniscience and omnipotence can be used in other worlds... but it consumes a lot more energy."

"Even if you really gain the power of the Demon God... let's not talk about the world of Magical Index! But in other worlds, you may be required to use your own energy to support the consumption of the Demon God's power."

"The energy required for the ability to change the world...are you sure you can afford it?"

Illya's cheeks were a little pale. She thought about it for a long time, and finally had to admit that what Aizen said made sense. Fortunately, I have completely stopped thinking about the world of A Certain Magical Index.

Although Su Han didn't speak, his eyes were shining with an inexplicable luster. I feel that Aizen's inference is indeed very possible.

"What a great inference! As expected of you, Aizen-kun." Conan was the first to applaud.

"This is just a guess. Guessing is actually meaningless... Unless a demon god actually appears in the council! And the demon god goes to other worlds to perform tasks... Only then can my judgment be confirmed."

Aizen paused for a moment and looked at Accelerator. He smiled and said, "Accelerator-kun, do you want to try to become a demon? After all, with the help of the power of the evil god, the incompatible nature of superpowers and magic should not be able to restrain you."
