Han Ni was visibly taken aback by the words. What kind of operation was this? He couldn't help but laugh, "Are you joking?"

Zhang Xuan chuckled, "I'm serious. Han, your cultivation from the Qi Refining stage to the Dao Palace stage is incredibly chaotic. If you could make some adjustments, your strength could at least double. Your cultivation has been forcibly elevated by pills."

With a wave of his hand, Zhang Xuan conjured a human silhouette between them. He pointed to three areas: the dantian, the heart, and the mind. "Your foundation in Qi Refining was very weak. It's not too late to remedy it. For example, you can use the Baihui and Tianchi acupoints to compensate for your deficiencies, thus patching up the flaws in your Qi Refining stage."

Han Ni was utterly shocked. This person's skills and insight were comparable to those of an Immortal. Even the Sages he knew didn't possess such vision. He hesitated and asked, "Are you really just here to guide me?"
