Leylin_Farlier Ok... Ignore what I just said... After doing some research online, this is his cheat.
It starts out with a beginning almost identical to HSSB. MC is reincarnated in the villain role. After he kills the psycho hero, who also happens to be a reincarnator after a bunch of chapters, he gets something and enters God's Space or Overgod Space (This name is the same as the God's Space in Terror Infinity and functions much the same). Due to the thing he got from the psycho hero, he gains privileges and finds out no one is in control of God's Space (divine artifact Overgod Palace) at the moment. The first half is his struggles to become the true owner of the Overgod Palace.
Overgod Palace is actually an artifact that belonged to a dead snake being, who is a distant descendant of Leylin. Its ability is basically to select contestants from whatever world it's in and sent them to other worlds for missions. Once the contestant dies, their truesoul is harvested for their insights. Its purpose original purpose might have been to discover the way to reach level 8 and beyond by studying various worlds (in immortal cultivation, it is called universal golden immortal (level8) as opposed to golden immortal (level7), which is restricted by the world/dimension/universe they are in, when they leave their home world they weaken)
