Chapter 667 The Stuffy Room

• The diluent was quickly prepared. To improve air circulation, a fan was used to blow directly into the stuffy room. Yinanlu was ready to extract the gas from the room at any time and observe the dilution effect.
• By evening, most of the gas in the room had been diluted. To be cautious, Lao Shen decided to wait a little longer before fully opening the room to ensure there was no remaining gas inside.
• This wait lasted throughout the night. Unlike at home, they didn't have everything readily available. When they were hungry, they could only eat some instant macaroni, and when they were thirsty, they could only drink mineral water. The young people weren't afraid, but it was different for Lao Shen. With his old age, he shivered when he crawled into the sleeping bag. In the middle of the night, Lao Shen had to warm himself up with alcohol.
