Garan, at this time, was indeed in deep shit.
After expending some effort, he took down the rock monster by controlling metal spikes he sent into its mouth. It took a while because it was not easy to control this way. He could only create metal coming from his own body, and it was more difficult to control if he could not see it.
The sensation was very much like putting a thread into the needle hole, a comparison his wife thought of, and he felt it was quite apt.
It was a challenging fight that required his full concentration. He did not even realize where he was being taken, tens of kilometers from where he met the monster.
He then used a large amount of mana to turn ice into steam. Turning ice to liquid water inside something's stomach had minimal damage, but turning into steam expands it more than a thousand times in volume.
The attack created a rupture inside its stomach (or whatever it had) and caused massive internal burns, finally killing it.
