Ye Xiaoqi and old du subconsciously stopped in their tracks. They had also realized that something was off.
The spiritual Qi in the Qing Yu realm was abundant. As long as one's talent was not too bad, they could cultivate to the sky origin stage. Elder Zheng was one of them. Of course, in the Qing-Yun realm, where the Saint level Masters were just beginners and the grandmasters were as common as hairs on a cow, the heaven origin stage was nothing.
However, even with old Zheng's cultivation at heavenly origin stage, he only took a few steps back after receiving Ling Chuxi's palm. This was unbelievable.
They could all see that although Ling Chuxi had held back with that palm strike, it still had the power of a Grandmaster. Logically speaking, it was impossible for elder Zheng to have such an easy time. He actually did not even suffer any light injuries.
The two of them looked at elder Zheng carefully and realized that his eyes were filled with chaos and killing intent.
