Xu Qing did what he said.
After having a direction, he immediately took out poisonous herbs and poison pills from his storage bag. Some of them were directly swallowed, some were smeared all over his body, and some were directly placed inside his body.
The effect was much better.
He didn't spare his eyes either. He turned poison pills into liquid and dripped it into his eyes.
The Poison Restriction mixed in with the poison and filled his entire body, nurturing his physical body's memories and refining his physical body's instincts.
Time flowed by and half a month passed.
During these more than ten days and nights, Xu Qing immersed himself in this process. Many times, he had double vision, but he did not give up.
Xu Qing understood that if he wanted to achieve the physical memory he wanted, not only did he need a lot of poison, but he also needed a variety of poisons.
