Apart from that, he also wanted to use the alchemy jade slip he obtained from the ancient cave abode to try to increase his alchemy to Level 7.
At that time, he would definitely be able to obtain some good things from the system.
He did as he thought.
Jiang Chengxuan immediately calmed down and began to seriously comprehend the relevant Earth rule.
Time passed slowly.
In the blink of an eye, eighty years had passed.
In the past eighty years, Jiang Chengxuan successfully comprehended the essence of the Earth rule, living up to expectations.
With this achievement, he only had the essence of Fire rule left to master.
Once he could comprehend the essence of Fire rule, he would be ready to attempt breaking through to the Dao Integration Realm.
Without wasting much time after mastering the Earth rule, Jiang Chengxuan started to experiment with alchemy, using the ancient alchemical jade slips he had obtained.
