The captain walked in with a smug expression and waved his right hand.
"How is it, Little Qing? Isn't my method of opening the secret chamber's door through the restrictions and array formation very magical?"

Xu Qing lifted his head and looked at the captain before looking at the secret chamber's door. A strange feeling rose in his heart. One had to know that he had also other than the restrictions in this secret chamber, he had also put some formations and rest them a few times.
Although it couldn't be said to be perfect, it was extremely difficult to open it so simply and silently.
However, the captain actually opened it so easily.
