Discovery

Once the moon was at the top of their heads, Anna and Melissa began to approach the tower.

Melissa stopped Anna when she was about to break through. She listened closely and said, "There are about four people."

"I know." Anna nodded. She could also sense them because of her unique instinct. "We'll knock them out. For the time being, our appearance here is not known by anyone. If we knock them out and get out of here without making our appearance here, we'll be able to play innocent. The only problem is what we will find inside the basement."

"In that case, I'll knock out the two people on the right."

Anna agreed. "Let's go."

The ones guarding the basement were actually spirit wielders. They were very strong. Even if a spirit grandmaster came, they would be able to put up a fight for a few seconds and sound the alarm. 

However, no one would expect for two spirit transcendences to actually sneak into the tower.
