When the glimmer of "material fusion" breaks through the mortal world, ordinary people combine with the fragmented materials and become fusions who can control fire, rocks, and healing power. B-level and above primary fusions can peel off the core of the material and create secondary fusions - they may be defense legions to protect civilians, or killing tools to plunder resources, or they may be wanderers who awaken their consciousness and break free from fetters.
Zhao Lei's Civilian Guard Corps and Li Lan's Law Enforcement Corps stick to justice, Zhou Kai's black market plunderers, and Wu Tong's experimental reformed soldiers wreak havoc, while Zhao Mei's Forging Corps and Qian Ming's Transport Corps vacillate between interests. When the S-class Wu Tong created experimental sub-subs with no autonomous consciousness, and even gave birth to S-class subs with overwhelming combat power, the mortal world fell into the flames of war between factions, and countless sub-subs struggled between control and awakening.
The mysterious Lu Jin is the source of materials for all fusions. He does not interfere in disputes, but leaves a log containing fusion logic and purification formulas. In the end, the awakened secondary alliance broke the shackles and joined forces with the righteous and neutral camps to fight against Wu Tong's plan of destruction. But after the war subsided, the "unknown material core" in the hands of the fugitive villain was quietly brewing a new crisis - the fusion order of the mortal world will eventually be rewritten again.
