Chapter 286: Heart-wrenching Sound

Professor Chen stood outside the warehouse to chat with the two men for a long time before they walked in.

Su Ruan turned to Auntie Wang again and asked whether this man was the Professor she had mentioned earlier.

Auntie Wang's expression turned uglier as she nodded. The old woman continued to stare back at the warehouse with such hatred. She wanted to go over and beat that old man to death. However, the guards were restraining her movement.

As they did not know what was the situation inside, Su Ruan decided to wait until Professor Chen came out of the warehouse again.

Suddenly, there was a loud roar, coming from the warehouse. The sound was so loud that it was scaring everyone who was listening to it.

However, the moment Su Ruan heard that sound, she could feel that it was harder to breathe.
