Chapter 309: This is Professional

Although Tang Yuxin's hand was still a bit bruised, her veins were clearly visible. Her skin almost seemed transparent, making it easy for anyone with a firm grasp of their professional knowledge to locate the veins. Bearing in mind, everyone had been practicing injections for quite a while, to the point where the chances of missing the mark were slim to none.

Sun Yumeng took the needle and was about to jab it into Tang Yuxin's hand, not bothering to sterilise it first.

"You didn't sterilize it," Tang Yuxin reminded her.

She had no desire to get infected.

"You're so annoying," Sun Yumeng rolled her eyes at Tang Yuxin. There was an urge to tear Tang Yuxin's face apart.

She sterilized hastily and jabbed in the needle. Tang Yuxin suddenly felt a sharp pain at the back of her hand. Her forehead broke into a cold sweat instantly.

This was not a jab into a vein, it was a stab into the skin.

"Sorry," Sun Yumeng quickly withdrew the needle, causing blood to seep out from the puncture.
