As book friend Favorite Luo Lixing said, it is indeed necessary to correct that Type-Moon is officially called a god, which is correct. However, the view that nature is personified is one-sided. There are still a large number of pure believers in gods, such as the so-called embodiment of beauty and the embodiment of human longing, and the power of gods is not entirely derived from the touch of nature. The departure of gods is not the so-called recycling power of Gaia - this needs to be noted, it should be the imagination of the person who added the entry, which has obvious contradictions.
First of all, even the gods of nature are just extensions of nature. They are not on the same level as the planets that represent nature itself. Moreover, the powers of the gods have not been lost and are still there. It is just that the laws have changed and it is difficult to use them in modern times. Since they are still there, there is no way to talk about recycling them.
Professor Leif's full name is Leif Lionel Flauros. As you can see, he is a schizophrenic.
They are Lev Uvall, the personality that controls the past. He wants to recreate the Age of Gods and make the world and theorems that once existed in the past re-enacted in the modern era. In FGO, he talks about humans losing the favor of the king all day long. This is probably his personality. I like oranges.
The personality that controls the future - Lainur Gusion (ライノール?グシオン), whose mission is to measure the future, and to make magic flourish even at the expense of the past and present. The person who created the lens "Queen of Sheba" should be this personality. I like Aoko.
Finally, Mr. Flauros, the personality in charge of the present and the mediator, ignored the future in the past, and the future denied the past. The reason why these two completely opposite things can go smoothly is because there is a "present" to mediate. He also committed suicide, pitted the gay master, and saved the people's reason - he thought that the research of the other two guys would harm the present sooner or later, so he committed suicide.
In FGO, he is extremely concerned about Mashu, which is different from everyone else. Even in the end, he was the one who was confused and hesitant because of Mashu, so Mashu is said to be the most critical node. Of course, if you insist on being serious and say that Leif personally admitted that this is not the case, but the details in FGO are already very obvious.
In the end, the only thing that can shake Leif in FGO is the inhumane sub-servant experiment, which is also the biggest black history of Chaldea. In other aspects, Chaldea is full of good people, and Fufu has not grown up after staying here for so long. Think about the evaluation of Ishtar in Chapter 7, who said that if it was thrown into a human village, it would grow into a super scary monster in a week. It has been in Chaldea for so long and it is still like this... It shows how noble these guys in Chaldea are.
Let me digress a little. Please note the names of Leif's three personalities. Huale, Guxin and Flauros are the names of the seventy-two demons. Therefore, Professor Leif is most likely the combination of the three demons. As the last chess piece of General GAY, he is worthy of this status. It's a pity that a traitor appeared in the middle.
