MTL - Virtual World: Conquering the World - Chapter 1019 Underground sky

Two heroes of the game Legend of Heroes 2 who were rotten waters*.

When Fang Zheng opened his eyes, he was surprised to find himself reborn in a fantasy world of magic, dragons, knights, and princesses. Not only that, but even the game system that Fang Zheng had designed before also followed him into this world. Then, his next step would be to traverse thousands of plains, gain endless strength, become a brave hero, defeat the devil, marry the princess, reach the apex in life… wait, wait, wait, before all that, why was he reborn as someone who everyone called a cultist?

A tree of 10,000 flowers, the world is the door.
The spells change a lot, but the hearts of the people are unchanged.
