From this strike, Su Yang already knew that the assassin's strength indeed surpassed Lü Donglin's.
Lü Donglin was a bit stronger than Su Yang, but after Su Yang had killed the Terrestrial Immortal, the gap between them was not large.
However, the fact that Smiling Hidden Knife was able to send Su Yang retreating three steps with a single palm strike showed that his strength was considerably greater than Su Yang's.
Lü Donglin struggled to get up but ultimately didn't have the strength to stand.
He was already seriously wounded from his battle with Lü Wenbang and had then been ambushed by Smiling Hidden Knife, who stabbed him through the chest. Then, after exchanging a palm strike with Smiling Hidden Knife which caused him internal injuries, he had no strength left to heal himself and now most of his clothes were soaked with fresh blood—his condition was extremely critical.
"Su Yang, you go first!" Lü Donglin said through gritted teeth. "You are no match for him."
