Cao Yin's fractured left leg gradually completed the reduction under the operation of the "blood of the skeleton", and the pain at the fracture site became weaker and weaker, and he faintly felt that there was a warm energy surrounding the tissues of the fractured site, promoting the self-healing of the left leg, and he couldn't tell whether it was a real feeling or an imaginary illusion.

Cao Yin carefully pressed the location of the fracture of his left leg, which was almost intact, and he couldn't see any scars, so he nodded with satisfaction and thought: "This SZK-3 injection is more effective than I thought, and such a serious injury with a fracture can be healed quickly. ”

Lin Xinran only gave Cao Yin two boxes of SZK-2 injections at that time, and each box only had four injections, which were red, orange, white and green vial packaging with four cap colors, and at present, Cao Yin still had one SZK-3 orange label injection left in his backpack, and two SZK-3 injections of other colors.

Cao Yin remembered that Lin Xinran had said that the SZK-3 injection with an orange cover can accelerate the healing of various wounds, the white one can strengthen physical resistance, the green one can strengthen perception and reaction, and the red one can strengthen the strength of the body.

"There is still an orange SZK-3 left," Cao Yin subconsciously touched the injection box plate in the bag, and said secretly, "This injection is so useful, maybe you can rely on it to pick up a life at a critical moment, and the rest of it must not be used casually." ”

Cao Yin held the merchandise counter with both hands, stood up with only his right leg, and when his body stood firm, he slowly lowered his suspended left leg, let the sole of his left foot slowly touch the ground, and then gradually exert his force.

If discomfort is detected in the process of supporting the left leg, it is best to temporarily rely on the right leg and a cane to stand and walk, otherwise it is equivalent to wasting an orange reagent.

When his left leg and right leg were supporting Cao Yin's body upright, he didn't feel any discomfort in the fractured part of his left leg, and tried to jump a few steps, but there was no big problem, and he finally breathed a sigh of relief.

It seems that the healing ability of SZK-3 orange standard reagent is really extraordinary, as the saying goes, "a hundred days to break the muscles and bones", after the injection of injection, it will take more than ten minutes to complete the healing of the two fracture wounds, Cao Yin admires the medical technology of the Diying Group from the bottom of his heart, this healing speed can be called a medical miracle.

However, the awakened people with other blood deformities do not have the memory function of "Shadow Blood", so it is impossible to rely on the power of their own blood to correct the bones, Cao Yin is a little curious if if they also suffer a fracture This kind of injury can also be healed so quickly, then what do they rely on to repair themselves?

Thinking of this, Cao Yin felt that he might just be a special case, no matter how miraculous the SZK-2's orange label injection was, it was impossible to automatically repair all types of injuries, especially those that could only be repaired with the help of external forces.

Cao Yin's previous injury experience can also be used as evidence, as the heart of the human body has been shot twice, but both of them did not die, the blood of the shadow can automatically push out foreign bodies (bullets) inside the body, and can continue to maintain blood circulation throughout the body when the heart is damaged.

If it weren't for the power of the "Blood of the Shadow", Cao Yin would have died in the administrative building of Hengli Middle School long ago.

Every time you activate the ability of Shadow Blood Refining or release blood mist, you need to cut your body parts to create bleeding wounds, but every time you activate the ability, these wounds begin to heal automatically, and there is no doubt that it is also the recovery power of Shadow Blood, Cao Yin knew that he didn't have this special function when he was a child.

However, for an awakened person like Chen Yutu who only strengthens his eyes, without the intervention of external medical means, he will certainly not be able to heal himself from serious injuries such as heart bullets, fractures, fractures, and cuts in the arteries, but the healing ability of Li Yehua's "Healing Strings" and "Shadow Blood" is similar, the difference is that "Healing Strings" must rely on self-will to achieve, while the healing and life-sustaining abilities of Shadow Blood are unconsciously activated, because "Skeleton Blood" has the incarnation of self-will, "Red Butterfly".

After the injection of SZK-3 orange standard injection, there is another unexpected effect, that is, Cao Yin found that all kinds of symptoms of hypoxia have also been alleviated to a certain extent, and it may be that SZK-3 orange standard injection strengthens the healing ability of "shadow blood" at the same time, but also strengthens the oxygen supply capacity of the blood itself.

Cao Yin took several deep breaths with satisfaction, under the torture of hypoxia, every breath of air was an ultimate enjoyment, and after taking a deep breath, he sat on the floor against the counter, touching his stomach and licking his lips.

At present, the problems of fractures and lack of oxygen have been solved by injections, but hunger, fatigue and thirst still make Cao Yin tired, so he simply continued to lie on the floor pretending to be injured and sick, waiting for Xiao Beichen and Huang Lin to bring food and drink.

Time passed minute by minute, Cao Yin leaned on the counter and waited a little impatiently, feeling that it had been too long, at least more than an hour, but the two of them still did not come down, nor did they hear any movement, this commercial and residential building had only a few floors, and it didn't take much time to find them one by one.

"These two people are fine," Cao Yin stretched and got up from the floor, "That Xiao Beichen deduced that there would be no zombies in this building, according to the battle outside just now, some zombies had already run out, so the chance of them being attacked by zombies is not very high, it may be that they will encounter more tricky guys." ”

Cao Yin stared at the staircase of the black hole, and after pondering for a while, he was still about to go upstairs to see what was going on, just when he just stepped into the stairwell, a burly figure suddenly flashed on both sides of the door, and they stretched out their strong and powerful hands to grab Cao Yin fiercely with considerable force.

"Wow!" Cao Yin didn't expect to encounter a sneak attack, and wanted to break free from their grip immediately, but found that his arms and torso were completely immobile like iron shackles.

"Don't move, be honest!" Listening to the voice, it was a middle-aged rough man, and he twisted Cao Yin's arm and asked viciously, "What did you kid do?" ”

"Oh it hurts, it hurts, please take it lighter, you guys...... Who are you? Cao Yin's arm was twisted to the point of being broken, and his facial features were squeezed together in pain, he turned his head to look at the two people who grabbed him, one of them had tattoos tattooed on his face, and the other was a flat-headed brother with a face full of meat.

"Did I ask you or did you ask me?" Brother Pingtou continued to shout in a rough voice, "Say! Were you sent by the debris of the rainstorm? ”

"Violent ...... Rainstorm? Cao Yin knew that he was referring to the survivor organization formed by the remnants of the famous gangster, so he hurriedly denied the relationship, and his head shook like a rattle, "No, no, I'm just an ordinary survivor, I just escaped here, can you let me go, my arm is about to be broken!" ”

"That's what that dog mongrel said last time, and it almost killed us, Malegobi!" The tattooed man slapped Cao Yin hard with his fat palm with a fingered tiger, and said, "Your kid and those two guys just now must be accomplices, even if they are not spies sent by the rainstorm, they must be here to loot resources!" ”

"I just passed by and wanted to come to find a stutter, I didn't know that this was your territory, the two big brothers didn't remember the villain, let me go!" Even if Cao Yin was slapped, he still accompanied the smiling face, and secretly prepared to launch the "Blood of the Skeleton Shadow", but he had no choice but to grab his hands and couldn't cut himself, so he hesitated to bite his tongue again.

The taste of biting his tongue was too sour, Cao Yin thought about it and decided to take a look at the situation before making a plan, the slap just now will make this bastard ten times repaid later.

"The movement outside the building just now, don't say you don't know, I can see it clearly," Brother Pingtou looked at Cao Yin's appearance and said coldly, "There was a giant zombie in the drop box just now, and the person it chased was you, right?" ”

"yes!" Cao Yin replied, "Whoever chases such a terrible thing can't run for his life, and then he fled to this building, I'm really a fugitive, accidentally broke into the territory of the two eldest brothers, and please let the younger brother go!" ”

The big man sneered, with malicious greed in his eyes, and he said slowly: "You are the awakened person of the blood deformity trait, I saw that you took off into the air and took off to the top of the traffic light when you were chased by the giant zombie just now, ordinary people definitely have no such skills." ”

"Yes, that traffic light has to be at least seven or eight meters high!" The tattooed man said, "Heavy rain was snatching airdrop supplies nearby just now, but I didn't expect a monster to come out, and it was made miserable by the military, this guy is also nearby, and there is no doubt that he is the same party of heavy rain!" ”

"And you obviously looked weak and seriously injured just now, but now you look like you're nothing," Brother Pingtou suddenly took out a dagger and pressed it against Cao Yin's neck, and said in an unquestionable tone, "Tell me, what kind of abilities do you have?" ”

Cao Yin was speechless for a while, he didn't know how to answer, he naturally didn't want to show his ability, at this time, the tattooed brother's eyes lit up, he grabbed Cao Yin's shoulder straps, and said fiercely: "What is it here, bring it to me!" ”

As soon as he heard that the other party wanted to snatch his bag, Cao Yin's face suddenly became gloomy, he squinted his eyes and glared at the tattooed brother fiercely, and replied dissatisfiedly: "You dare to pull it again, you also touched the things in this bag?" ”

The tattooed brother obviously didn't expect Cao Yin to suddenly change his face, and he was still holding him hostage, when the flat-headed brother saw Cao Yin's hostility, he immediately pressed the blade of the dagger against Cao Yin's throat, and his cold tone contained a threat: "Don't you want to live, do you think that you are an awakened person is amazing?" ”

Cao Yin had a plan, the corners of his mouth raised an arrogant arc, glanced at Brother Pingtou with very contemptuous eyes, and said: "Yes, you can move me to try, you spicy chicken that has not been planted, there is a kind of cutting off my carotid artery!" ”

"You think I don't dare, do you?" Brother Pingtou's eyes emitted a fierce light, and the sharp dagger slashed at Cao Yin's neck.

The wound on Cao Yin's neck immediately erupted into a blood-red mist, enveloping the three people in the stairwell in the blink of an eye, Cao Yin looked at Brother Pingtou and Brother Tattoo, their expressions now were not only surprised but also a trace of fear.

Cao Yinyin smiled and bowed down, stroked the cut on his neck with his fingers, and said indifferently: "Red Butterfly, take off the left calf of these two people." ”

"No problem."

The crisp sound of two tight silk strings was fleeting, and immediately after the terrible screams of the two big men and the gurgling sound of blood gushing out of the blood mist that filled the stairwell.
