"So, how big is the planet?"
"About 317 million square miles."
Gong Ren nodded in understanding before leaving for the back room, but a few minutes later, he returned to Zhang Xiaolong [3], carrying hundreds of palm-sized devices with him. "At first, I thought your planet was as big as this realm, but it turned out to be so small, and all these devices are more than enough to help you clean the air on such a small planet. You only need to spread them in the sky, and they will automatically absorb the pollution. The air will be completely clean in a month, but I can't guarantee whether the Qi will return."
"A month?" Zhang Xiaolong [3] was surprised to hear that the process was so fast, especially since he initially thought that it would take several months or even years. "How many devices do you use in this realm, Senior?"
