In the following ten days, all of Zhou Yuan’s energy was invested into learning the Thousand Poisons Erosion Rune. After all, the method Yaoyao had chosen this time was a little on the fiercer side, and it was very likely that the sickly Wei Bin would die if even the slightest mishap occurred.

Therefore, Zhou Yuan had no choice but to redouble his enthusiasm to ensure that he would not be killed by a Wei Canglan turned crazy due to the loss of his only son.

After about seven days, Zhou Yuan had managed to grasp the Thousand Poisons Erosion Rune. Next, he would have to practice.

Great...
