Sam walked into the lab and all that was heard for some time is some screaming and begging along with some explosive sounds and the crashing sounds of the laboratory building and when he is done with it, the building completely collapsed as Sam walked out along with the head researcher.
He scouted the rest of the village for the guards and researchers. He didn't spare the houses of the test subjects and after confirming that there are none left, he knew he was done here.
He didn't even take a second look at the test subjects and walked out of the village towards the waterfall at the cliff that he came from. He dragged the head researcher along with him. He tied him up with the same cultivation restriction collars he has been using on the test subjects and just for the sake of it, he broke his limbs.
