"Tunfuwen" was found, but Chu Nan was worried.

the reason for Chu Nan's worry, or in the control, was that Chu Nan had figured out both "energy absorption array" and "shenglidan". It can be completely controlled, and it will not let the blood demons absorb the yuan force without limit, nor let their vitality and strength grow forever, but it can make them strong to a certain height.

that "shenglidan" doesn't meet the requirements of South Chu, but for the blood devil clan, it's OK to make do with it. However, this "shenglidan" also provides many ideas for the "zenlidan" that South Chu himself needs.

they don't know all this!...
