So Zheng Yichen sent him a piece of enhancement material and asked him to do a match first to see which one consumed the least merit points, and then gave him a complete piece of enhancement material.
After all, the enhancement on the Dusk side also has requirements, such as blood, which can't be just a drop or two, but needs a certain quantity.
Regarding the items provided by Zheng Yichen, Du Gang was not polite and happily accepted them, indicating he would treat Zheng Yichen to a meal next time they met.
On the Dusk side, Zheng Yichen looked at Du Gang's reply, compared those materials, and even the cheapest one required 31 merit points for enhancement, which was higher than Tanshia Firlo's by more than ten points.
Zheng Yichen could understand this situation, besides the compatibility of enhancement materials, the remaining issue was individual strength.
