The blade cut through the hard black skin, and blood that was nearly coagulated slowly flowed out, mixed with a trace of viscous black liquid.

Cao Yicong screamed in pain, and this heterogeneous limb suddenly became more violent, and Li Liangbin and Wang Yong were prepared to press together, making a gasp and hiss. Despite the fact that both of them were tall men and tried their best, they could barely hold it down, and they had to be careful not to be splashed with black liquid.

But if they put in the effort and put in more effort, they will be able to accomplish their task.

For Gu Jun, strength is only one of them, as well as eyesight, calmness, skill, stability, and so on.

He was on one knee on the ground, with the small open medical box next to him, and the instruments and medicines were arranged.

Because the intended osteotomy plane was only about 5 cm from the shoulder blade, the anterior and posterior isometric flaps he designed were very short, and with just a few cuts, the skin and deep fascia were cut along the incision line. The limb tissue above this has not yet mutated, the skin is the skin, and the deep fascia is the deep fascia.

But this alien limb is constantly struggling, and the scalpel in Gu Jun's hand has to change accordingly with the swing caused by its struggle, just like a small boat sailing on the stormy sea, not being overturned by the storm, but controlling the storm.

"It's not ...... My hand ......" The heterolimb is being amputated, but what Cao Yicong gets is not comfort, but another kind of pain, approaching delirium.

After pulling up the flap, Gu Jun looked for the brachial artery vein on the inside of the biceps brachii, the gray sky cast a gray light, which was difficult to compare with the shadowless lamp, and there was no help from the first assistant or the second assistant next to him, only his own hands.

In his left hand, he held the dissecting forceps to clamp the blood vessel to make it visible, and in his right hand, he took the suture needle that had been threaded through the sheep intestine, double-ligated the blood vessel, and then cut it off with a scalpel.

Sweat was already running down his forehead, and every stroke had to be done with great care, and the slightest carelessness would cause heavy bleeding.

Li Liangbin looked even more nervous than the chief swordsman, be careful......

He and Wang Yong didn't understand how they could pick and pick out the blood vessels from the pile of flesh and blood when the light was dark and the operation area was blurred.

There are also various treatments to be done...... But they didn't see the scene of blood flowing like a pillar, and the not clear surgical area could still have some surgical fields.

Under this condition, Gu Jun cut off all the arteries and veins to be severed, and then injected 0.5% procaine to the proximal end of the osteotomy plane for local closure, and then cut off the radial nerve, median nerve and ulnar nerve, and these nerves can also be naturally retracted to the proximal end of the osteotomy plane, and then the muscles.

The two onlookers sighed in Gu Jun's heart, the needlework was so good, and his fingers were really firm as a rock.

At the same time, they became more and more worried about Vice Captain Cao.

"Hand ...... It's not my hand......" Cao Yicong's whole body struggled even more, and the complexion of his face was close to purple black.

Gu Jun has always paid attention to the situation of the injured, and from time to time he would say a few words of encouragement, or talk a few words to check the other party's mental state, and then said: "Deputy Cao, hold on a little longer, and it will be fine soon." Now you need to show your will, no problem. ”

Cao Yicong's complexion was constantly changing, fighting against the dark forces, and ordinary people couldn't bear it anymore, "Cut it off...... Chop ......"

At this stage of the operation, the difficulty has become the cutting and trimming of the muscles.

Gu Jun's hands have gradually become accustomed to the rhythm, the hand is fast, the blade is faster, cut the muscle and then pull it to the proximal end with the posterior flap, try to make the stump cylindrical, so that the postoperative installation and use of the prosthesis will be better recovery; The blade then cuts the periosteum in an annular way to the osteotomy plane, and then peels the periosteum distally.

There was no periosteal dissection in the small medical box, which he did with the handle end of the dissecting forceps.

There was no blood coming out of the operation area, but the black fluid was flowing more, and the lesions of the heterogeneous limbs were more bizarre.

It's not just the blood vessels that are writhing, it's not just the muscles that are writhing, it's the bones that are writhing, and I don't know what kind of structural changes are happening.

Gu Jun knew that time was running out, and if he didn't remove this strange limb, Deputy Captain Cao's life would be difficult to protect.

Li Liangbin and Wang Yong were sweating profusely, and their strength couldn't last long, they were still holding on in one breath......

But they finally saw a layer of bones, humerus, and the long bones of the upper limbs, which were normally very hard.

The humerus is almost bounded by the predetermined osteotomy plane, with normal bone color above and a mutant bone surface with faint black dots below, encased in a musculofacia that has become like saprolite. The rate of mutation is much faster than that of ordinary people with heterodysesis who are admitted to the Department of Medicine.

At this point, the next step is the osteotomy.

Use a high-powered bone saw to cut the bones sideways.

That's a bone saw or whatever.

Now, Gu Jun held the Kalop scalpel in his right hand in a grasping position, stared at the exposed bones in the operation area, and took a deep breath.

"Ah......" Cao Yicong shouted, struggling, and trying his best to support, Li Liangbin and Wang Yong pressed him with dead force, trying to fix the heterogeneous limb. The three of them were already at the end of their crossbows, and every vein and nerve was tense, crackling and breaking at any moment, scattering all over the ground.

Gu Jun closed his eyes, his mind quickly entered that state, and then opened them again.

At this time, he is like one with this scalpel, the knife is the continuation of the hand, and the blade is his will.

The biceps and tripleps of his arm suddenly exerted force, forearm, wrist, palm, fingers, knife body, blade, this force was connected into a line, penetrating and falling, Huo Di swung rampantly towards the humerus in the operation area, click! Hit the target.

There was a resistance to resist, but as soon as he gritted his teeth, the strength in his hand was greater, and the blade suddenly had a sense of penetration, breaking through the bone surface-

Li Liangbin and Wang Yong were simply dumbfounded, the situation was very different from what was expected.

Their sanity has always been reserved about whether this knife can see bones, and if it can, it should have the effect of being as brilliant as an old seal.

But the truth is that there is no spark, and there is no abnormal light, it is like chopping melons and vegetables, going in and coming out again.

Suddenly, the alien limb and the injured person were separated, Cao Yicong shouted with relief, and Li Liangbin and the two used their last strength to throw the alien limb to the side and avoid the splashing black liquid.

It's just that immediately, Gu Jun's eyes condensed slightly, Li Liangbin and Wang Yong were also shocked, only Cao Yicong himself was unaware.

Perhaps, this humerus can be cut off by a scalpel, firstly because the blade is sharp enough, and secondly because of the bone itself......

The bone tissue inside seems to have been evacuated, pumped to the end of the heterogeneous limb, decayed, and sucked.

Cavities, bone stumps are hollow inside.
