Xingyue: Shall I Invade the Human Science?

After the Sultan traveled to the world of Xingyue, he awakened the Hall of Valor system at the beginning. Being able to contract with heroic spirits, being able to travel to the era where the heroic spirits belong, being able to profit from the heroic spirits... The functions are all right. But putting such a function in the hands of restraint is the Hall of Valor used to control the world. And put it in my hand... I can steal heroic spirits from the inhibitory power, I can create singularities in every era, and I can also make myself stronger in the process. Isn't this inappropriate? It's a human intrusion into the system! So... I'm going to invade the human system? This novel and its characters are purely fictitious.
