Demonic Realm: I Cultivate Myself to Survive in the Dark City

[Single male protagonist + system + multiple female protagonists + light and refreshing text + upgrade flow] Han Zihao was reborn because of a live broadcast accident. At the same time, with the birth of the system, various game demons descended on the city and ran rampant, leading to the break of the civilized era and the opening of a social system for national cultivation. He grew with the resources rewarded by this body and system. The demonic realm tears apart the sky and descends on the modern city. Monsters bite people, order collapses, technology fails, and the world becomes a purgatory. In the darkness, some people degenerate into demons, while others linger on. However, in despair, Han Zihao awakened the cultivation system and used his mortal body to reach the path of immortality. Temper your body to slay beasts, gather energy to destroy evil spirits, and condense elixirs to suppress demons! He maintains gentleness in despair and kills in darkness. Don't be a virgin, don't be pretentious, live on, and stand on top of the world. When the devil looked down at the human world, all the demons roared together. Han Zihao slashed his sword across the air: "My city does not allow monsters to run wild."
