In the end, sumo broke through the shackles of the dreamland and successfully rescued Bai Ying and Zhen Lan who were caught in the dreamland. Then Zhen Lan resisted the feather illusion that came to make trouble. Sumo took the opportunity to use the "Sword of Heaven" to perform "mirror splitting" and successfully lifted the first dragon seal.
However, the second seal was laid by Bai Wei 7000 years ago to protect the dragon god from being destroyed, so it can only be lifted by Bai Ying, the descendant of Bai Wei. After inheriting all the strength of Bai Wei, Bai Ying successfully helped sumo break the second seal and released the dragon god.
Unfortunately, however, in order to unlock the seal of the dragon god, sumo learned the "mirror splitting technique" taught by Xing, which conflicts with the "power of the dragon god", so sumo can no longer live with the power of the dragon god.
In fact, this is also a foreshadowing for Yan Xi to replace sumo as the next seafood and accept the power of the dragon god, because in the finale, sumo will sacrifice himself to protect Quan Xian and Bai Ying, and it is doomed that Yan Xi will replace sumo as a seafood.
