Indeed, Li Xiuyi's intuition was spot-on.
Li Yun was the one behind this.
With Li Yun's strength, once he knew something was wrong on the western side of Horse King Mountain, he had no need for Zhang Qi as a tool, much less any heart's blood.
With a quick analysis by the Gate of Myriad Wonders, he entered the hidden treasury with ease.
The treasury did indeed hold a wealth of resources. All sorts of Heavenly Materials and Earthly Treasures lay piled inside, worth a fortune, and the Eternal Thunder Pool Li Xiuyi sought was also hidden there, completely intact.
