It skipped so many important arcs and moments in the story. For example the ancient city arc where he became an advanced mage and fought over a million undead. His mentor also sacrificed his soul to stop the undead monarch. All this happening while also skipping the world college tournament, the attack on the patheton by the titans, the patheron trying to kill mo fan sister Xin Xia because of the spirit inside her ,the birth of the moon moth phoenix,going to the underworld to open the gates to the underworld, the building of the a new city where he visits after he unlocks the earth element and becomes a savior for the city and gains the power to vote twice in their election for mayor. Maybe this will be shown later but they just showed scenes from him before season 6 meeting Liu ru the vampire and the chiwaka morsiki girl who was a teacher for the Japanese students and also the red demon from years in the future.so he went from an intermediate season 5 to an experienced advanced mage season 6 to a super mage in this small season
