Ever since he found out that the six realm battlefield was created by someone else, Zhao Hai had decided to speed up his own development. If he wanted to develop, he could not rely on his own strength. His strength was not at the top of the cultivation world, so if he wanted to develop his own power, he needed connections, a lot of connections.
The six realm battlefield was actually a good place to develop connections. Didn't you see that Ma Rulong and the round Guardian were already on good terms? the round Guardian wanted to stay in the six realm battlefield to take revenge, so he didn't go out. If he went out and something happened, Ma Rulong would definitely help him. After all, the two of them had been through life and death together.
