This is Cia's last chance. His mana was drained to a negative value, and it would take him a few months before he could use his mana again.
Carrying Ain, he let the system check if there was something wrong with his body, and after receiving a negative answer, Cia secretly placed Ain inside the house and peeked into the old man's room.
The old man saw his attire, and Cia was not sure if he saw it right, but the old man's eyes twitched a bit when he saw the mask.
"Is everything done? You're not in a really good shape. Are you sure you don't want to rest?" The old man was not the system who could monitor Cia's mana, but just based on what he was feeling, Cia was teetering on the edge of collapse.
"I'm fine. I'll be back soon. But don't die yet." Without waiting for the old man's reaction, Cia flew off.
...
It was a bit unexpected to Cia, but despite what happened, he still saw Ugan sitting near the trash bin, his eyes staring brightly at Cia.
