Title

Zhou Chen and the long-haired girl observed the charred remains on the ground for a while and left after confirming that it was completely gone.

Half an hour later, they passed the cave and arrived outside an underground palace-like building.

The door of this palace-like building was open. Through the Bloodthirst passive skill, Zhou Chen could sense a few monsters near the door.

After entering the palace and killing the few weak monsters, he found a tightly closed bronze door.

This bronze door looked very heavy. The keyhole on the door told the person that they needed the corresponding key to enter.

Zhou Chen immediately took out the key he had obtained from the trap room and tried to open the door, but he quickly realized that it did not match.

"It doesn't match again?"

He felt a little depressed as he left the place to search for the key.
