ตอน 519: Chapter 356: What Kind of Monster Is This?_2

Sean Knight didn't expect such a situation, but he had already pulled the ring and threw the hand grenade directly at the monster's head!

And one after another!

It seemed that the lungfish were also afraid of Sean. After Sean killed the first lungfish, the others that rushed forward started to eat that lungfish, leaving Sean alone to throw the grenades with ease!

He threw five grenades in total and then stopped.

However, he felt only three explosions. Two were duds.

The huge monster was blown to pieces, and Sean guessed it wouldn't attack him again, so he immediately floated up.

After all, his oxygen was running low now.

As for the things below, he didn't plan to deal with them anymore.

Anyway, the water was flowing down, and these creatures didn't seem to have the will to come up. Or perhaps the water channel was winding, and these big creatures couldn't make it up. If some small ones occasionally came up, they would probably become food in other fish's mouths.
