Shi-Woon (man, he gets a few) goes up against Yoo Ji-Gun, a sword master who uses his finger and tells, to his face, that he is not strong.
Shi-Woon: I know strong people. They never bragged about their power, or bullied others with it. ... Your sword is a fake!
Alex can drive a helicopter. Can YOU drive a helicopter? 'Cuz hecan.
Chang Ho is back, and now knows murim techniques and can break arms with. So what does Shi-Woon, who has a broken arm and no ki or martial arts, do? Square up to him, taunting Chang Ho by saying he will never fear anyone like him again. And not only dodges the Megaton Punch, but hits Chang Ho in the back of the head, making it look so easy. Awesome doesn't even describe it!
Chapter 76-79 is one long one-sided beatdown of Shi Woon wrecking SUC members while protecting people behind him. The beatdown is so bad that the remaining soldiers, when they notice that Shi Woon can barely stand up straight are still too scared to attack him. Then, when their captain comes to fight him, it's revealed that Shi-Woon was holding back to avoid killing them.
Chapter 80 of New Waves: Shi-Woon completely wrecks the arm with a power stomp of S.U.C. captain, Yong-Hyun, while it had a metallic gauntlet on before winning the fight.
Between chapter 102 and 107 of New Waves, Shi-Woon after entering into the equivalent of Black Origin Threshold while going against S.U.C. captains.
Chapter 110 has Shi-Woon wake up in a hospital after the events of the previous arc and quickly seeing through the plot to use him as a Puppet King. The moment he gets a minute alone, he breaks out and manages to get 5km in 30 minutes. He's done being held hostage and played. The beatdown and escaping continues for over 4 chapters as he tries to escape the island and curbstomp everyone in his way.
Pretty much Chapter 110-current has been one long Crowning Moment Of Awesome. Mainly because up until 110 he has been very weak, but now we get to see Shi-Woon utterly curbstomp everyone in his path.
Though it is not as if Kang-sung is exactly lacking, either. He quite easily curb-stomps anyone who isn't Chun-woo and, despite losing once Chun-woo got serious, he managed to leave Chun-woo visibly exhausted. Compared to all previous showings, the fact that Kang-sung even kept up Chun-woo for so long deserves mention.
