*Boom*
Shang Dongzhu was thrown back after his fist collided with Zhang Fei [5]'s. He hurriedly stabilized himself and looked at him with narrowed eyes. 'What exactly happened? Did he use a strengthening technique? For a split second, I felt his strength became equal to mine, but it has since returned to normal.'
Shang Beixuan, Shang Nanzhui, and Shang Xijiao looked at Zhang Fei [5] in disbelief. Shang Dongzhu was the strongest among the four asura guardians, but he was able to knock him back. However, they couldn't sense the change in his strength, which lasted only a split second.
Zhang Fei [5] stood in the air as he looked at Shang Dongzhu. "What do you think of the power of my punch just now, Senior?"
"Not bad." Shang Dongzhu still narrowed his eyes, trying to analyze the qi within Zhang Fei [5]'s body. "I don't know how you did it, but I'm sure you used a strengthening technique just before our fists clashed."
