Baitao is the owner of the Wish House. His original identity was an immortal cultivator. Later, he was bound by something claiming to be the system. The two reached a contract. The system took Baitao to other worlds, and Baitao needed to divide his merits into half of the system (Baitao needs merits to ascend).
There is everything in the world. This world is the existence of matryoshka dolls. Each world has a script, which is better said to be the future. When those novels become the real world, there will be loopholes in these worlds. What Baitao needs is to eradicate these loopholes to gain merit.
Purpose: source of happiness
