Actually, Liu Dong was waiting for Liu Chan to get out of the arena. So that Liu Dong could act and save Liu Chan but Long Ryu was so merciless that he didn't let Liu Chan get out of the arena and humiliated him again and again. That was the reason Liu Dong took action to save Liu Chan but his hatred took over him and he tried to kill Long Ryu.
Long Ryu wasn't afraid when he saw the punch come he was relaxed. Because he became number 1 as a pro gamer because there was an ability that he got as a gamer. That is micro-movement and the synchronic rate was 200%. It was double the average max rate. So when Liu Dong was throwing a punch he was able to see the punch trajectory. Long Ryu was able to see where the punch was going to hit then he made a distance from the punch-hitting point and kicked at Liu Dong's coming punch from the side. Then a small dragon-like thing came out of Long Ryu's feet and bite Liu Dong's hand wasn't letting it go. Long Ryu then jumped in the air and twisted his body to throw out of the arena.
When Liu Dong was sent out of the arena he tried to get into the arena again but his hand was grabbed by someone and kaccha, It broke in an instant. The one that was grabbing his hand was the patriarch of the Liu Clan and the father of Long Ryu Liu Bang. Even though Liu Dong was a nascent profound realm 8th stage cultivator Liu Bang was a nascent profound realm 9th stage cultivator and a little bit away from True Profound realm 1st stage cultivation. When he came to the stage himself Liu Dong can only let himself be punished for his deeds.
Patriarch's action didn't mean anything to the audience's eye because what Long Ryu just did was an impossible feat. He just blocked a punch from a nascent profound realm 8th stage cultivator with just cultivation of elementary profound realm 6th stage. Even though he couldn't scratch Liu Dong and Liu Dong wasn't using any martial art but he was able to push Liu Dong out of the stage by himself. Some of the elders and the patriarch saw the martial art Long Ryu use just now was a 4th-grade martial art but he wasn't allowed to enter the 4th-tier martial hall because of his low-level cultivation then how could he learn that and even able to use it because only a nascent profound realm cultivator could use 4th and 5th tier martial art successfully.
The martial art Long Ryu just used was martial art he got after combining two 3rd tier martial art for the 1st time. The name he gave this martial art was 'LONG RYU ORIGINAL: WORM'S ASCENSION. Liu Bang was grabbing Liu Dong's crushed hand tightly then he asked him in an angry voice, "How dare you? You were trying to kill him in front of me. Did you though I won't do anything to you? You wait until the tournament is finished your punishment will be decided in the elder's meeting. Judge continue the match."
Actually, Long Ryu had planned all this from the beginning of the match. He was watching Liu Dong's reaction when he humiliated Liu Chan. He was trying to kill Liu Chan just now he was forcing Liu Dong to take action to save Liu Chan. Liu Dong just falls into Long Ryu's trap. Long Ryu said to himself in his mind, "Motherf*c*er you were eying for the patriarch position now you will have to face the consequence."
The judge came to the arena. He was a little afraid and asked "Long Ryu do you want to continue this match?" "No, I don't want to continue this match anymore and continue the next rounds." "Ok, Then someone take Liu Chan out of the arena and the semi-final will begin now pick up the lots." The judge said to the participants. Everybody took a lot and saw the number. Long Ryu got lot number 2 and Liu Bia got to number 1. Then the match begins Liu Bia have win against her opponent and advanced to the final. Then the match between Long Ryu and Liu Yue begins but when she remembered Liu Chan's state she didn't have the courage and surrenders quickly. The final round was between Long Ryu and Liu Bia.
