[Leveling up, powered armor, no System, one female lead]
The monsters from another world known as Mech Beasts have the traits of Earth’s creatures, but their bodies are covered in mechanical armor. Bloodthirsty and warlike, they launched a massive invasion of the human world fifty years ago.
Among humanity are those known as Mech-Bound, who awaken at eighteen to a Soul Mark corresponding to a Mech Beast, gaining its abilities and armor. They can also obtain Mech Beast cores by killing them and use those cores to make Contract Cards, allowing them to wield the power of more kinds of Mech Beasts. Thus began the long struggle between Mech Beasts and humanity.
Ye Lingyi is attacked by a beast horde during his awakening ceremony and gains the ability to fuse the effects of Contract Cards. From that moment on, he sets out on a path of cultivation to end the conflict and explore the many possibilities of Contract Cards...
[Lion] Roaring whirlwind + [Wizard] Fireball attack = Fire tornado
[Falcon] Flight + [Cheetah] High-speed movement = Ultimate speed
[Pterosaur] Lightning control + [Warrior] Mastery of swordsmanship = Lightning-enchanted swordsmanship
“How come your Contract Card abilities are different from ours?”
“Don’t you think you have a few too many skills?”
“Why is he still using skills?!”
Years later, Ye Lingyi stands in the rift between the two worlds, gazing down at the peaceful lives of humanity and looking toward the gaze fixed on him from beyond the universe. Alone, surrounded by a hundred cards, he silently draws his weapon and strides into the heavens.
