How Could They Have Gone Missing?!

Mu Lei's stomach churned after he identified the objects in the bottles! They were different kinds of human internal organs! The alchemy lab was, in fact, a human anatomy laboratory. It was very typical to find these types of laboratories in the modern era, but it was scary and terrifying to the ancient civilization as they had not seen them before!

Mu Lei was too busy to stay shocked at this time. He realized that Long Siye and Ye Hongfeng were not in the lab! The layout of the lab was relatively simple even though the lab was ginormous. However, even though they could see every corner of the room inside the lab, they could not find Long Siye and Ye Hongfeng.
