He Had Been Shy Before

Even if Gu Xijiu and Di Fuyi's abilities could prevent the little devils from hurting them, once an alarm was sounded, Yun Yanli's subordinates would enter into his lair, and they would not be able to hide anymore. Hence, it was necessary to subdue them. 

After he was done with the little devils, Di Fuyi started to store the unaffected spiritual crystals into his own storage space and left the guarded crystals untouched so as not to alarm anyone.

Meanwhile, Gu Xijiu had already found a secret door for them to continue moving forward. To open this door, one had to possess at least a level nine spiritual power. In the past, Gu Xijiu was unable to open the door. But this time, she could! 

She opened the secret door in just a few seconds and found a pathway made with jade behind the door. This jade could absorb all the light in the area, so when the door was opened, the hallway looked completely dark.
