After reading the autobiography, Chi Shuyan didn't put it back. Instead, she put it in her Cosmos Ring and planned to take it out with her.
As for how to deal with the queen insect in the rotting corpse in the black coffin, Chi Shuyan had a headache. The palace was filled with a dense swarm of bugs, which numbered in the hundreds of millions.
It was easy to deal with thousands or tens of thousands of bugs, but as for hundreds of millions of bugs… Chi Shuyan couldn't help but have a headache.
Moreover, the yin energy in the old Liang family residence was too strong. It was no wonder that Ancestor Zhuang had fixated on the Liang family back then, and even got the idea of raising a corpse in the old Liang family residence.
Because of a Yin Gathering Array and the Yin Corpse Nourishing Array, these bugs reproduced very quickly over the years. Insects especially liked yin energy, so it was impossible for them not to reproduce quickly.
