Chapter 657: Li Kai, it's getting heavier and heavier on my back

Li Kai looked at the number displayed on the air quality detector and immediately called Qin Lin.

He wasn't a fool. If he thought that the air quality was normal, he would be abnormal.

In the office.

When Qin Lin received Li Kai's call and heard his urgent question, he knew that Li Kai must have noticed the abnormal air quality in the manor.

He asked for Li Kai's location before hanging up. He then placed a bag of seeds on the table into the drawer.

this bag contained the seeds of the purification grass.

After discovering the effects of the purifying grass, the first thing he thought about was whether he could cultivate it.

although the seeds required level 3 land, even if they were cultivated in special soil outside, the quality would be greatly reduced.
