Since Lu Chuan was kicked out of the cultivating world, he started his daily life of ruining things for thousands of years, until one day he accidentally picked up a chance system.
"Host, as long as you complete the task, you will receive rewards. Then it will not be a problem to dominate the world."
So his blood that had nowhere to put it had a place to be put to use. When Lu Chuan holds the system, he can dominate the world.
