In the end, Tong Wudi left as if he was running away, leaving only Li Chu and the big glazed immortal tree.

Li Chu looked in the direction where Tong Wudi had left. In just a moment, he had turned into a cloud in the Northwest sky. He thought to himself,'no wonder he's the No. 1 in the world. His speed of flying on the cloud is unprecedented.'

However,

If he ran away, what would happen to the tree?

Li Chu looked at the immortal tree again.

Just now, Tong Wudi and Li Chu had tried to avoid it. No one wanted the appearance of this tree, so the glazed immortal tree was obviously angry. At this moment, he was still standing there with his hands on his waist and looking away from the tree crown, as if he couldn't be coaxed.

You can't coax her?

Li Chu blinked and cupped his hands at the immortal tree. thank you for your help this time, venerable tree. I'm really grateful.

Then, he turned around and left.
