Qingfeng, Monk, Bald-man and Death-God opened the rock gate and went down into the underground castle. Alice, on the other hand, stayed outside to watch for changes and deliver support if necessary.
They immediately found the secret tunnel to the underground castle based on all the information and the map of the villa that Alice had gotten.
The tunnel entrance was a human-shaped hole made of rocks which allowed two people to walk side by side at the same time. Qingfeng was walking ahead, Monk and Bald-man were in the middle and Death-God was the last one. Even though the four of them were walking separately, they kept their eyes on each other all the time so that they could avoid any dangers if enemies appeared from different directions.
