Although Mouse Da didn't know what continuing to practice would achieve, he knew that since Senior Brother Xinghe said to keep practicing, there couldn't be anything wrong with it!
As Mouse Da and his brothers' Avatars were continuously lost in the Deathly Realm, the entire realm became relatively quiet.
Nowadays, those Shadow Ghosts gather every day, waiting to attack the Avatars of the Shadow Mouse brothers. As a result, the number of Shadow Ghosts attacking the seal has greatly decreased, and the pressure on the seal has naturally lessened.
Thus, the seal gradually returned to peace!
