Cao Zhen heard the other party mention expanding the Blood River and immediately shouted, "Not advisable. Everyone, if more Blood Rivers are opened in this land, the spiritual energy of this area will be affected. Furthermore, once the Blood River is widened, who knows what else you might do, since we're not familiar enough with you."
This is the Human Clan's Great Thousand World, and he knew the impact of the Blood Clan's Blood River on their Human Clan long before he entered the Golden Core Stage.
He would not allow these Blood Clan members to expand more Blood Rivers in their Human Clan's Great Thousand World.
Actually, if all clans truly want to coexist peacefully, the first step is to return the land of the Human Clan back to them.
However, he did not bring this up because he knew that even if he did, the clans would not agree.
