Chapter 1309: Is this a helmet and protective suit?

minister lu was really shocked. he stayed in the water for a while and finally couldn't help but jump out of the water.

After he got out of the pool, he couldn't wait to remove the bubble from his head and asked Qin Lin, " Minister Lu, this bubble seems to be able to provide constant oxygen.

Qin Lin smiled and explained,"Minister Lu, isn't it amazing?" It's all thanks to the crystal that grew inside the bubble. The crystal can absorb the air that people breathe, and then react to produce oxygen."

the most important thing is that when I tested it, I found that this bubble also has the ability to filter harmful gases. It's amazing.

"It can filter harmful gases." Minister Lu murmured. His eyes were very bright. It could provide oxygen and filter harmful gases. He could already imagine what this thing could be used for.

"Boss Qin, how long can the bubbles provide oxygen?" he asked immediately.
