Of course, Yang Chen knew that it would not be easy to break the Undead Ghost Qi in a short period of time. If his current set of materials didn't work, he could try other materials.
With that in mind, Yang Chen pondered in his mind, came up with a feasible set of materials, and called the two female cultivators over to prepare them.
The two female cultivators hurriedly prepared, and in less than half a day, the materials were brought back to him.
Yang Chen received the materials and entered the research state once again.
Unfortunately, it was still a failure.
This made Yang Chen frown and switch to another set of materials to try again.
In the end, he had tried six different sets of materials, which kept the two female cultivators busy, and even Yang Chen felt a little embarrassed.
Gradually, Yang Chen also realized.
After trying six different materials without success, it could be seen that the failure was not related to the materials.
The key should be something else...
