He took out all three tubes of reagents, threw them into the safe, put one in each side pocket of his coat, and held the remaining one in his palm, hesitating whether to keep it himself or give it to Si Di for safekeeping.
But soon Xiao Zhenyun no longer had this worry, because in the next second, the man guarding outside the door noticed something was wrong, turned around and opened the door with a gun in hand, aiming at the two uninvited guests in the room.
Si Di and Xiao Zhenyun looked at the man's face at the same time. What surprised them was that this man was none other than Si Chu, who had washed his neck and offered himself to be acupunctured!
Xiao Nian had secretly crawled out of the underground passage at some point, kneeling behind the desk with half of his face exposed to observe secretly. Seeing Si Chu suddenly rushing into the room, he screamed in surprise, hiding in the shadows and frantically gesturing to Xiao Zhenyun and Si Di, asking them to run away before being recognized by Si Chu.
Subconsciously, Xiao Zhenyun also took a half step back, raised his right hand to touch the mask on his face, to ensure that Si Chu could not see his face. At the same time, the cold glass tube of reagent was pressed against his eyelids when his fingertips touched his cheek. Xiao Zhenyun reacted instantly, raised his eyes to look at Si Di, and happened to meet the pair of green eyes hidden under the hood.
There was no need for any detailed communication in the mental link; the two of them came up with the same idea, and a bold plan took shape in their minds in an instant.
After less than half a second of eye contact, Si Di, like a ferocious cheetah, took the initiative and pounced on the prey without giving it any chance to react. He used the fastest speed in this attack without holding back, as he would not be so arrogant as to underestimate the strength of an A-level sentinel.
So Si Chu was so surprised that he didn't even have time to fire his gun. He was disarmed by Si Di, whose arms were twisted and pressed to the ground. His waist was also pressed against his knees, and he was unable to move for a while.
"Hurry." Si Di deliberately blurred his voice and covered Si Chu's eyes with one hand to prevent accidents.
Without saying a word, Xiao Zhenyun bit open the cover on the front of the reagent with his teeth, pressed out the needle of the reagent, and the bright yellow medicine dripped onto Si Chu's struggling body.
"Nooo ...
Although Si Di felt very sorry for his brother who was about to suffer, he would not hesitate or be soft-hearted since he had made the decision. The sentry moved sharply and decisively to force Si Chu to tilt his neck back, exposing his fragile neck.
Next to the protruding Adam's apple is the blue winding carotid artery. Xiao Zhenyun knelt beside Si Chu, not daring to touch the thickest blood vessel. The tip of the needle approached the thicker veins nearby, and after a brief psychological preparation, the needle instantly sank into the skin.
Nurse Xiao, who has poor technique, gave the patient an injection in the neck for the first time without disinfection. One can only hope that the A-level sentry has thick skin and can survive this punishment.
Si Chu struggled all the way. He broke out in a cold sweat when the cold medicine was pushed into his blood vessels. His hot breath sprinkled on Xiao Nian's wrist. Si Di frowned reluctantly, but he remained firm and silent. The strength in his hands was as solid as a rock, firmly controlling Si Chu.
