First of all, he wanted to help his master, Valerio Piroddi. Valerio had once been an Origin Martial God, but now his cultivation was stuck at the Extreme Void Stage because of an old injury. Alex wanted to heal those injuries and help him regain his former cultivation so that he could leave the Essence Sky World and return to his original world.
At the same time, Alex also wanted to give Valerio either the Undying Fruit or the Life Creation Core. However, giving him the Life Creation Core would mean that Valerio would never be able to break through to the Death Domination Stage or beyond.
Secondly, Alex wanted to face Atticus Finch and ask why he had betrayed his trust. If Atticus failed to give a satisfactory answer, Alex would not hesitate to get rid of him.
After leaving Selyara and Elyndra to roam the world freely again, Alex disappeared and reappeared inside the Profound Star Sect.
