Rat Chase.

An old man appeared inside the room where Zhu Lin was resting. He looked around but could not find anyone. The old man was perplexed, but upon searching again, he found the same unknown man appearing in another corridor. He vanished from the spot again to find nothing. 

Meanwhile, Shi Lang walked inside the old man's room. The place was decorated with minimal stuff. Shi Lang spotted the tile under which lay the treasure vault. He pressed it gently, and a click was heard. 

The blood had seeped inside already, so he was sure this thing had no traps. The tile sunk under the pressure and slid to the side, revealing a big black pit. Shi Lang sensed the place and found an anti-flying array engraved on the walls. 

This was a trick to prevent people from stealing. Such arrays could only be negated with special keys, but Shi Lang did not intend to return with the same route. He had something else planned. As he was entering the vault, he also controlled his clones.
