Against Xiantian

The Yuan Principle started making the spirit sea tumble. The still water became tumultuous. The old man who had entered Liu Feng's spirit sea started clutching his ears, as if this noise was bursting his head. 

This was the same reaction that Liu Feng also had. But Liu Man seemingly could endure it. 

"Suppress!" Liu Feng shouted, and the Yuan Principle doubled. 

Going against someone in the Xiantian realm, he could not afford to show off his cards. Although he had never fought in his spirit sea, he knew that the Yuan Principle could exist there. And he had no intention of experimenting by using the Dao of Ice here. If something happened to his spirit sea that would damage his consciousness, then he would probably enter a vegetative state. 

"Who are you? To think that you actually have a spirit attack. But do not think that you are almighty." the old man said and his eyes started turning red.
