Infiltration
"Courtesy of Uncle Leo, I guess," Rain thought. "This shouldn't be small enough that a single earth magic can clean fast enough… This also should have happened before the attack."
The blocked exit at least confirmed that Rain could use the tunnel freely. At least until he finds the entrance. He didn't know who that tunnel once belonged to, after all. It was better to be safe than sorry for a while longer.
After not so long, Rain moved in the opposite direction, and after one hour, he reached the other side. He found a door leading to an area above, but it was sealed tight. Rain could also see some dust falling from the breaches of the door. He imagined that a building above had been knocked down. Probably a result of the invasion or someone who had a grudge against the Lonard family.
"I guess they destroyed and left as if it was anything that was connected to the previous leaders of the city… I can't hear anything around, but I need to be careful," Rain thought.
