Inside the Great Formation, Xiao Yi sat cross-legged, cultivating.
Several days later, he briefly stopped.
Even though the concentration of Spiritual Energy inside the Spirit Gathering Array was ten times that outside,
it was still not very effective for him.
Of course, it was much better than not cultivating at all.
During his free time, he took out the Ten Thousand Poison Treasure Book given to him by the Poison Emperor.
After flipping through a few pages, Xiao Yi's eyes lit up.
The Ten Thousand Poison Treasure Book was written by the Poison Emperor himself.
It recorded all the poisons the Poison Emperor had encountered in his lifetime.
These included tens of thousands of poisons, some were Heavenly Materials and Earthly Treasures that grew in remote and perilous places with potent toxins;
some were fear-inducing demon beasts with deadly venom; and some were rare items with astonishing toxicity... and so on.
