Jim kept running towards the worm while that worm wasn't able to do anything to him with all its tentacles being cut in half with Jim.
"Shriek!"
The worm shrieked in a threatening way while Jim was only a few meters away. "Eat this," Jim wasn't fazed and the next moment he shot the ore piece he had in hand directly towards the worm.
He couldn't clearly see anything but the moment the ore passed out the slit opening of the crack, it hit something hard.
And Jim only pushed it with all his might. "Get in," he gritted his teeth while pushing it as hard as he could.
"Shriek!"
This time the worm shrieked in a pained way while Jim felt his ore crushed something and went deeply inside the flesh of that worm.
And the moment that happened, that worm started to twitch violently, making his body twitch with it.
