When nine-tailed spirit fox saw the bronze coffin, it instinctively showed great fear.

The three little golden crows did not dare to approach, wind wolf had long been hiding far away, only purple gold eagle had been looking at the bronze coffin.

"Master, this coffin is very dangerous. The contents frighten me." Purple gold eagle said.

Nine-tailed spirit fox nodded and agreed with purple gold eagle.

However, Ningtian is not afraid.

"It's okay, I'm sure."

Ning Tian said, the root of the tree began to wrap around the bronze coffin, Ning Tian's method is very simple, forcibly removed the bronze coffin seal magic sword.

As for the way to lift the seal, Ning Tian said that there was no need, just dismantle it violently.

Of course, the consequence of this is that Ningtian cannot dismantle it. Ningtian wrapped it around the roots for half a day. As a result, the bronze coffin did not respond at all.

"What is this bronze coffin made of, so hard?"
