Having dealt with the most difficult aspect, the only thing left was to find the critical points that were present in both special abilities. The greater the number of similarities, the greater the possibility of a successful fusion.
As for those similarities, he had already found 3 of them.
The first one was that both were at the divinized realm. His azure fire was already at that level. As for his darkness attribute special ability, it had, in fact, reached the divinized realm after the stimulation it had received from the Fate Stone after the duel against Gui Xinying. Although he still wasn't too used to controlling this divinized darkness attribute special ability, he also didn't have any corresponding moves that he could unleash. However, at the very least, the 2 special abilities were at the same realm.
On the other hand, both of them shared the aspect of combustion, which was undoubtedly another similarity.
