Looking at the huge blood pool in front of him, Zhao Hai was a little hesitant. Although his strength had increased greatly, if he made too much noise here, he would be discovered by others. If he didn't know the people who came, he would just kill them. If he knew them, he couldn't do it. However, if the other party knew his strength and spread it out, it would be very disadvantageous to him.
Zhao Hai wasn't worried about his own safety. He believed that there really wasn't anything in the demon blood world that could pose a threat to him. However, if his strength was exposed now, it wouldn't be a good thing for him.
