Season 3.5/4
In China, Season 3.5 was never recognised as a full season - it was never given a name. However, according to the English Auldey website, it is known as "Season 4".
Liam starts with a brief summary of what happened in season 3. They are still looking for suitable players (3A, 5A) for their team. Liam and Kelvin[Chen Kai] go to Shanghai, to look for the legendary 3A player that is supposedly scary. After some encouragement from Sandy, Liam and Kelvin[Chen Kai] reluctantly go. Jacky heads to Beijing, to look for a 5A player, and visit Mrs. [Weng], an elderly lady who supposedly taught Jacky 4A. It is hinted that the 4A player Leo[Li Xiang Yang] from Dylan's team, Tornado, is the grandson of Mrs. [Weng]. (Please do not confuse with "Super Tornado Team" in Season 3).
In Shanghai, Liam drags Kelvin[Chen Kai] to an arcade. He plays one game and he receives the highest score. One very short teenager challenges Liam to a game. However, Liam rudely rejects that person, and calls him a "child" and "immature". Little does he know that this "child" was the legendary 3A player he was looking for and he was already in his last year of junior high.
Liam and Kelvin[Chen Kai] temporarily reside at Charles' grandmother's house. They ask Charles whether he knows anything about the legendary player. He takes out his yoyo... it was damaged by this legendary player. Liam swears revenge.
When they go to find the legendary player, Liam mistakenly thinks someone else is the player. However, he realises that the short guy he met at the arcade is the legendary player. He challenges him, saying "the winner shall have his wish granted". They start their challenge. David[Lin Xiaozhi] wins, and forces Liam to become his slave.
David[Lin Xiaozhi] is actually a very lonely guy. Many people think he uses his yoyo to do bad things to others. Liam realises this and they eventually become friends.
On the other hand, in Beijing, Jacky sticks around Mrs. [Weng]. Apparently, her grandson is one of the two who are trying to stop them finding team members. He is the 4A player.
In the second arc (unfinished) of Blazing Teens Season 3, Dylan asked his team to stop fighting Chinese yoyoers unfairly. Three people do not listen - respectively the 3A, 4A and 5A players. The 5A player is a girl.
Mrs. [Weng] and her grandson have not been friendly with each other for a long time. Mrs. [Weng] desperately wants her grandson to forgive her. Knowing this, the 4A player tries to make Mrs. [Weng] hurt Jacky with acupuncture and other things. Jacky changes their views.
Jacky goes to another city to recruit a 5A player. Dylan's 5A player infiltrates their team and causes havoc. Sandy is nearly driven away from the team but Jacky refused to believe that that 5A player would do such a thing. She almost damaged the team's yoyos.
