Tang Feng didn't take the blow head-on but instead used Void Shuttle to appear behind the elderly man.
One has to admit the old man's abilities were indeed extraordinary. The moment Tang Feng appeared, the old man detected it and swung around with a backhand palm strike.
This time, Tang Feng took the palm strike head-on.
He was pushed back dozens of feet.
His palm felt numb, and this was just a casual blow from the opponent.
This old man had the strength of the Tribulation Crossing Realm. How could such a powerful cultivator exist in the Kunlun Ruins?
During Tang Feng's last visit, he hadn't discovered anything like it.
However, he soon realized that the Kunlun Ruins might be connected to the Cultivation World from the Outer Domain, and others from there had already arrived.
It was merely Xiao Yao's misfortune to encounter such a powerful expert; otherwise, he would have gotten away with it again.
