Who Knows, I Cultivated the Devil and Became a Saint

The paranoid demonic cultivator keeps silent and kills to chase the top. He originally wanted to do evil all his life, but he had no intention of killing the great evil in the world. He accumulated countless merits and became a saint in the underworld. He stepped into the heaven to rectify the heavenly soldiers, took command in an expedition to the demon realm when the crisis came, and fought against the demon emperor alone to quell the foreign invasion. He abandoned the false reputation of good and evil, followed the way of heaven with a demonic heart, was trapped in the chess game for half his life, and silently guarded the people of the three realms for the rest of his life.
