Chapter 335: Nightmare Crystal

A dark hall spread in front of Marvin after turning the corner.

However, he unhesitantly broke into a sprint!

His movement was still utterly silent, and he quickly approached the limits of Human running speed!

Gwyn was briefly surprised, but he didn't think too much about it and chased after him.

"What are you doing?" he asked in a low voice.

Frankly, if it weren't for Gwyn being so confident in Marvin, along with his previous dazzling performances, he wouldn't be fine with following him to run around all over the place in here!

This was Saruha, and he had seen how those previous scouts died.

If the first wave was an ambush of Tentacle Horrors, then wouldn't there be even more powerful monsters inside?
