Pollution 160

With the stone castle, we could create a large isolation space where the outside air could be filtered and exchanged, thereby avoiding the huge problem air pollution posed.

Yu Hong guessed that his lack of coughing was likely due to spending a long time in the cave, coupled with his constitution being far stronger than others.

There was no time to lose. To solve the air detection issue, he needed to find some air detection instruments first.

And there were definitely none at the camp.

Coincidentally, he also planned to go out and test the specific radiation killing power of his Inner Qi, and whether the camp's array would fail again, just like the luminous grass, once he left.

Without delay, Yu Hong returned to the cave, changed into his gear and weaponry, and without acknowledging Old Zhou and the others, he swiftly left the camp, sprinting towards the nearest town at breakneck speed.
