"Don't worry about these trivial things now, the most important thing for you now is to defeat Devilmon. Otherwise, more kind Digimon will be controlled by Devimon's black gears, and this world can only be saved by you." In response to the questions of the studious chosen children, Leomon bluntly changed the subject and did not forget to give them a wave of PUA. Leomon also wanted to know why Seiya could transform back into the juvenile stage of Ballmon after evolving to the mature stage. Theoretically speaking, after the Digimon in the Digital World evolve through their own power, they should always maintain their evolved form. The reason why the Digimon of the Chosen Children degenerate is that the power they use when evolving originally comes from the Chosen Children, and is not obtained through their own training or data increase. To put it simply, Digimon itself is a group of data, and when the data reaches a certain limit, the Digimon will appear in a completely new form, which is the so-called "evolution." The data needed for Taichi's Agumon and others to evolve depends on the power of the chosen children. So after the battle, this power will naturally return to the divine plan. As for why Seiya, as a native Digimon, can evolve and degenerate on his own, Leomon really doesn't understand this. Even though Seiya is a Digimon chosen by the children, he shouldn't have this kind of power.
In fact, Seiya has the power to evolve and degenerate on his own. The reason is very simple. In this world, his own data is that of a juvenile Ballmon. But after sharing the abilities of Seiya from other worlds, the extra power is the amount of data he needs to evolve. The more power Seiya shares with other worlds, the higher the level of Seiya's evolution will be. When Seiya does not choose to use power, he will turn back into Rollermon. This is not just for cuteness, but maintaining daily life in this form is the state that consumes the least energy for Seiya. "Rollermon, do you want to join us in fighting Devilmon?" Although Leomon just said that only the chosen children can defeat Devimon, the children saw the strength that Seiya just showed. In addition, Seiya had just saved them, so at this moment, Taichi looked at Seiya and invited him warmly. To be honest, Seiya has almost forgotten the details of how the chosen children returned to the real world. After all, this is also a series that evokes his childhood memories. However, if he wants to go to the real world, he can either hang out with Devimon or follow the protagonist group. Seiya is not very interested in being someone else's lackey, so naturally he can only follow the protagonist group. Seiya agreed to go with them, and the chosen children were very happy because they had a strong ally out of nowhere, and their chances of defeating Devimon became greater. Leomon was quite surprised, because as a local Digimon, he knew that although Seiya and Devimon had a bad relationship, he would not fight to the death with Devimon for the chosen children. Infinite Mountain is the base camp of Devimon. Devimon, who is recognized by the darkness of this world, has the power to create "dark gears". Seiya and his crew had just reached the mountain, and had not yet encountered the BOSS Devimon, but they first encountered a group of Digimon controlled by Dark Gears. Facing a large number of mature Digimon, Leomon drew the dagger at his waist and stood in front of the children. Then he looked at the children behind him and said, "Children, leave this to me and Rollermon. Go and defeat Devilmon quickly." Yes, while Leomon took the initiative to stay behind to cover the rear, he also did not forget to drag Seiya into the water. The reason why he did this was very simple. On the one hand, there were too many enemies controlled by the black gears, and Leomon could not handle them alone. On the other hand, Leomon is worried about Seiya and is concerned that he has ulterior motives in helping the chosen children. Although the chosen children are the hope of this world, they are still just a group of children who are too trusting of others.
Seiya is not as evil as Devimon, but he is definitely not a righteous Digimon. In order to prevent accidents from happening to the children, Leomon decides to keep a close eye on Seiya. Seeing Leomon struggling against several mature Digimon, Seiya evolved into Tyrannosaurus once again, and with a size far exceeding TaichiTyrannosaurus, he punched each of the Digimon that rushed towards him. Although they are both in the mature stage, anyone with a discerning eye can clearly see the difference. Even when facing the siege of multiple mature stage monsters, Seiya is still like a weakling. Even without using his special moves, he could easily break the black gears in the bodies of the mature Digimon in front of him with one punch each. "Leomon, you've been on guard against what I might do to those children, right? But you, who claim to be righteous, let those children fight the most dangerous demon beasts alone. Is this your code of conduct? " Seeing his purpose, Leomon did not quibble, but used the dagger to force back a Digimon in front of him, and continued: "This is the mission of those children. If it is up to them, they will definitely be able to defeat Devimon and restore peace to the Digital World." "Mission? What a high-sounding excuse! Just because they were chosen by this world, those children need to risk their lives to save the world? I don’t care whether you are a character arranged by the old man Xuannei, or a chess piece used by the World Tree to promote the development of this world, or whether you are acting according to your own consciousness. But if you get in my way, I'll kill you too!" "Like you said before, although I'm not as evil as Devimon, I'm not a Digimon who claims to be righteous, nor am I one of those gullible children. No one can arrange for me, not even the World Tree, my script can only be controlled by myself!" As Seiya finished his words, more Digimon controlled by black gears swarmed towards him again. Facing these Digimon rushing towards him, Seiya did not choose to hold back, but instead condensed a high-temperature super flame and sprayed it out! The high-temperature flames that were enough to burn the air instantly fanned out in a fan-shaped manner, turning the hundred-meter area in front of Seiya into a scorched earth. The Digimon that had previously blocked Seiya's way now all turned into Digi-Eggs that fell from the sky. Seeing such a brutal Seiya, Leomon wanted to say something, but soon they suddenly saw a large dark air mass suddenly covering the entire top of the Infinite Mountain. Those Digimon that had not been defeated by them had black gears flying out of their bodies and all flew to the top of Infinity Mountain.
