Lilin asked, "What have you decided?"
Lumila smiled and with hot evidence in her voice, she said.
"I will surely join his journey!"
Lilin nodded as she had already expected this. While Aarim was thinking what did her daughter see to make her happy to follow her mother's brother?
Lilin then made a few gestures in the air and told Eren and Lumila to do the same.
After both of them copied what Lilin did, a chain-like thing bound both of their souls
Now, both of them could feel each other's emotions and could even communicate directly with the brain.
"The contract is completed!" Lilin announced.

I skipped an important point.
I am writing this chapter on 21 December 2022. So, I don't know if some of you asked the question. Anyway, I will tell it.
Eren saw her sister in the game cuz she lived in the phoenix realm. The realm can be accessed from anywhere by a royal family member with the acceptance of a matriarch.
