The male protagonist travels through time and can combine armor. Armor includes man-made armor and naturally formed armor. During this period, I got to know the male second, and the armor levels are: early stage: armor level one to nine, middle stage: armor of earth level, heaven level, late stage: king level, emperor level, emperor level, and final stage: Yu level, world level, world level. It's about a male protagonist surpassing the second male protagonist, which roughly means that the second male protagonist is always bettered by the male protagonist. But the second male lead is really awesome! Although I don't know if I can survive to the mid-term in the end, I have to endure it slowly. I hope I can hold on until it's over.
