System: I Use All Worlds as the Great Wall

System version: I am just a system, assisting hosts one after another. Some of them started from humble beginnings, but became arrogant and blind after getting the system; some were extremely smart and good at maneuvering, but they were obsessed with conspiracy and died unexpectedly; some of them were extremely Buddhist and would not fight or rob, but in the age of great war, they had already been sentenced to death; some were already standing on the top of the mountain, but they regarded their fate as a must and were the enemy of the whole world... There are no perfect humans, only perfect systems. But no matter what, they are just my brick-moving contractors for building the "Great Wall". This novel and its characters are purely fictitious.
