Boom!
A terrifying surge of True Energy flowed out of Chu Tianzong, turning into a powerful airwave that instantly swept out.
Chu Yunfan instantly felt Chu Tianzong's strength jump from an ordinary seventh level of the Energy Refinement Stage to the peak of the seventh level of the Energy Refinement Stage.
That red pill could have obviously increased Chu Tianzong's strength. But in terms of effect, it was far from the One-Stripe Purple-gold Pill that Chu Yunfan had once concocted.
The difference in effect was too great!
However, this was also taking into account who Chu Yunfan was. If it was to an ordinary person, the effect of this red pill would have been sufficient.
