Two reasons

Li Futian opened his eyes for a moment and then closed them with a smile on his face.

A moment later, a strand of qi struck his tent, and the tent rippled at the impact.

"Come in." He shouted.

Four people entered the tent, and Li Futian looked at each as they entered.

"Fellow Daoist Jiang is finally here."

"Fellow Daoist Li looks well. Did you encounter any troubles since we separated?"

"Thank you for your concern. This Li did not encounter any problems."

"That's good to hear."

Jiang Yue then pulled Yu Nianzhen forward and introduced him to Li Futian.

"Nianzhen, he is Li Futian. Li Futian, this person is Yu Nianzhen. We belong to the same sect." 

When he heard that, Li Futian's eyes moved underneath his eyelids.

His face turned pale, and a line of blood appeared at the edge of his mouth.

"Fellow Daoist Li?" Jiang Yue was shocked to see what was happening.
