Ultra Monster Fighting: Infinite Fusion Evolution

On his birthday, Cheng Yan traveled to the Ultra World and by chance, became a Leonix. He found that his combat instrument seemed a little special. When defeating aliens, monsters, or even Ultraman, you have the opportunity to obtain a card with its ability. When attached to your own monster, it can be temporarily integrated and evolved to obtain new abilities, and there is a chance that it will be retained permanently. This is an earth where Ultraman and monsters have never appeared. This is a universe buried in conspiracies, where disasters are everywhere and people are restless. Floods, high temperatures, earthquakes, typhoons, aurora, solar eclipse... This is a manifestation of the existence of the six demon king beasts, and is also a precursor to the awakening of the Mog Serpent; The Kirialodians took the opportunity to spread rumors, rob humans of their faith, and enslave their bodies and minds, hoping to become the "savior" earlier; Leonixes from all over the universe have landed on Earth one after another, and this place was chosen by Ray Blanco as the main battlefield, looking for opportunities to resurrect; The Ultraman who came here lost their ability to transform and became ordinary humans, hiding around the world, waiting for an opportunity to defeat foreign enemies in one fell swoop; Humanity belatedly realized that the United Nations formed the Earth Defense Force to defend their homeland which was on the verge of collapse; Meanwhile… Emperor Gua has recovered; The legendary Hypa reappears in the world; Lucifer, the only remaining legend, slowly opened his eyes; In this regard, all Cheng Yan can do is to keep fighting, keep killing monsters, and keep getting cards...
