Deny the Beginning of Everything

Tens of thousands of years ago, the first generation of source nuclear nanonuclear warriors wanted to prevent the invasion of alien races and destroy the Eight Balance Dimensions. He simply relied on breaking through the constraints of his own dimension and developed the nuclear energy of the armor and his own power to the extreme, thus temporarily expelling all races from other worlds... After this battle, all the first-generation nuclear weapons fell, and the source core nanometers they left behind also lost their original source code due to the death of the host, resulting in it becoming a collection that cannot be used or studied. According to this, a hundred years have passed quietly, and the alien race Roxases, who was originally being expelled, secretly sent people to the Eighth Dimension to try to steal the first-generation source core nano-armor. And when the school was invited to visit the collection hall, they happened to bump into the middle-level soldiers sent by Roxas. The first-generation source core nano-armor, the first sequence of Long Yuan, was killed by a man named Long Yuan in the melee.
