Unexpected.

Shi Lang looked at the portal and then at the old men. He thought for a moment and asked, "Seniors, if you don't mind, may I stay here for the rest of the nine days?" 

The old men were surprised and they asked, "Why?" 

Shi Lang replied calmly, "The spirit storm is very beneficial to my cultivation. I gained a lot inside the storm. My realm is on a brink of break through. So, I wish to spend some more time here and then comprehend Dao." 

The old men exchanged gazes and then they nodded. Shi Lang bowed with them and then he said, "Thank you, Elders." 

The old men smiled, and waved their hands at him. The old man in the lead said, "It's not a big deal, you are the only person who has gone inside and come back from this storm. We have to thank you."
