The researcher whose finger was bitten endured the intense pain and gritted his teeth as he stuck the needle into the elderly woman's arm.
The researcher's face flushed red, exerting all his strength to inject the drug from the syringe into the elderly woman's arm.
"Ah————!!!"
A large amount of blood overflowed from the old woman's mouth, the flowing blood smeared her chin, and continuously dripped down to the collar and chest of her nightgown.
The one who screamed miserably was the researcher who injected the drug into the elderly woman; his face was now pale as a sheet!
The old woman finally let go of her mouth, spat towards the ground, and the severed finger—bloodied and mutilated—was spat out from her mouth.
"Ah ah ah————" The researcher who had his finger bitten off was drenched in sweat, as if all his strength had been drained away, he collapsed to the ground.
