The monitoring system indicated that the poisonous gas in the room was no longer at a dangerous level, but considering how deadly it was, Xia Fei still put on a gas mask as a precaution.
He opened the door. The exhaust fan was operating loudly. A large amount of gas was being released into the universe while fresh air was being pumped into the room.
Xia Fei lifted his arm and glanced at the value on the detector before entering the room.
The red box was lying sideways on the table with a little crack, from where the poisonous gas was released.
The poisonous gas had been fully released, so the box was no longer posing any threat to humans. Xia Fei put the box upright with a thick protective glove then he took a deep breath and opened the lid.
