Li Yun's expression was indifferent as he spoke. "What secrets does this underground palace hold that attracted your Ironblood Sect to enter? Also, who exactly is that crimson-robed youth, and what is his relationship with the Ironblood Holy Son, Yan Wuhen?"
"I will talk. I will talk."
Feeling the terrifying pressure of the Sword Qi, the black-robed cultivator did not dare hesitate in the slightest and hurriedly blurted out everything he knew.
A moment later, after listening to the black-robed cultivator's account, Li Yun could not help furrowing his brows.
Although the black-robed cultivator had said quite a bit, due to his status, his knowledge was extremely limited. However, it still gave Li Yun a general understanding of the situation.
It was said that inside this underground palace lay the legacy of an ancient and powerful sect. Any cultivator who could obtain this legacy would be able to ascend to the heavens in a single step.
