When Zu Wan found out that he lost his power, he realized that he needed time to figure out how he could regain his power back.
Being powerless couldn't help him at all. How could he create a portal if he didn't have enough magical power right now?
He was still weak physically. The only thing he could perform at his current state was teleportation which also required lots of energy.
After a few moments, he remembered Ella and Titania.
"Should I stay with them while I am still trying to recover my powers? I also need to know the reason why Titania looks like Eva."
Zu Wan was now considering staying with the mother and daughter. He was unfamiliar with this world. He might get in trouble since he didn't know how this world worked.
It was very different from his world. And he thought Ella and Titania could help him understand this world. He needed guidance from them.
