Seeing that all the medicinal ingredients in the Medicine Cauldron had been refined, Xiao Yu tossed in a Cold Marrow Branch, one of the main ingredients of the Sect Breaking Pill, and began the final stage of ingredient refinement.
Over the past two months, Xiao Yu had first used the origin heart flame to temper his body and cultivate.
After that tempering, Xiao Yu's physique had reached new heights.
Previously, without using any other means-including origin flame divine thunder, soul power, or Dou Qi-Xiao Yu could match a Da Dou Shi with his physical body alone. Now, his physical strength rivaled that of a Dou Ling, and a Peak Dou Ling at that.

This improvement was not to be underestimated. Dou Emperors who had never practiced body-tempering Dou Techniques or tempered their physiques generally had only Da Dou Shi-level physical strength, just as Xiao Yu had before.
