Strange observed a clear and clean surgical field of vision, only to realize that he did not notice when Chen Ang adjusted the patient's surgical position, but the surgical field of the retractor and window could clearly observe the patient's brachial plexus.

The ivory-white nerves, thin like silver threads, thick like tendons, are surrounded by membranous sheaths.

The black fungus is linear, has grown into the inside of the membrane-like sheath, the black fungus and the nerve are entangled, it parasitizes on the nerve, and the black veins spreading on the ivory white nerve are extraordinarily conspicuous. It was even slowly squirming, making Strange feel his scalp tingle.

The brachial plexus consists of the anterior branches of the fifth to eighth cervical nerves and most of the anterior branches of the first thoracic nerve, which exits through the scalene muscle space, runs posterior and superior to the subclavian artery, and enters the axilla behind the clavicle.

The fibers of the five roots of the brachial plexus are first synthesized into the upper, middle and inferior trunks, and the medial, lateral and posterior fascicles are formed by the three stem branches around the axillary artery, and the branches from the fascicles are mainly distributed in the upper limbs and part of the thoracic and superficial dorsal muscles. However, now the fungus infected by the wound has taken root in the medial, lateral and posterior fascicles, spreading from the three stem branches to the brain on one side, and developing to the thoracodal dorsal nerve, long thoracic nerve, axillary nerve, musculocutaneous nerve, median nerve, radial nerve, and ulnar nerve on the other side.

The main nerve roots have been infected, and the thinnest part of the black line of fungal infection has progressed to the nerve branches of the pectoral-upper limb muscles, superficial back muscles, and deep cervical muscles.

If the fungus infects the nerve endings, the consequences are dire, and the patient's entire upper limb will be controlled by parasites.

But now I can't take care of the nerves of the upper limbs, and go up along the three stem branches, which is the most complex cistern area of the brain, which is located at the bottom of the brain, which is the complex area where the brain, brainstem, and cerebellum intersect, and the nerve activity here is complex and precise, and it is the most important and deadly area of the human body.

Suffice it to say – surgery on the cerebral cortex and lobes is important, but even if the surgery fails, or some brain tissue is accidentally removed. It doesn't matter much, the patient will not die immediately, at most there will be some sequelae of being in a daze, mental retardation, unresponsiveness, and at worst - becoming a vegetable (vegetative), and there will be a long time for the attending physician to clear up the relationship.

There is enough time and reason for doctors to use various excuses to shirk responsibility.

So, this part of the brain has been used as a variety of important medical breakthroughs, such as the infamous anterior lobectomy surgery in the last century, and the mentally ill who had most of the anterior lobe removed are not also alive and healthy? And quiet, docile like a small animal, so much so that this operation was hailed as the dawn of a cure for psychosis.

This sensational achievement was not until it was discovered that the reason why the mentally ill did not fall ill was because they had lost the ability to commit disease, because they had become semi-vegetative, the most essential ability that distinguishes human beings from other animals, thinking, was deprived! When this mechanism of treatment was discovered, the procedure was declared illegal.

However, the cisterns of the brain are different from the lobes of the brain, which can be used for brushing fruits in the last century, and before the creation of microneurosurgery, it was called a forbidden area, and the mortality rate of surgery here is basically equivalent to that of a terminal disease.

It is also because microneurosurgery breaks through the cisternal exclusion zone that it qualifies as the crown of surgery.

As a former neurosurgeon who was proud of his profession, deeply honored, and devoted his life to it, knowing that his hands had been crippled by a car accident and had to switch to a legal profession, Strange certainly knew the trickiness of this position, and in terms of the danger of fungal parasitism in the nerves, once it spread to the cistern area, where neuroticism was enriched, the rescue could basically be declared ineffective.

He had to remind Chen Ang: "We must first stop it from spreading to the cistern, once it reaches the cisterna oblongata and anterior cistern oblongata, it can infect the brainstem and cranial plexus, and it can spread to the spine." If the infection reaches this level, there is basically no help! ”

Chen Ang calmly observed the fungus silk and said, "It's okay! ”

Strange nervously said: "We have to rush for time...... Are you still in the mood to say 'okay'? ”

Chen Ang replied unhurriedly: "It's really okay...... The fungus did not develop the plexus, they were still simple neural structures, which could be seen to parasitize human nerves, allowing it to mimic human neural structures, but did not continue to develop...... It's a blessing. That's it! ”

Strange watched the fungus spread on his nerves, and his heart was very anxious, and out of confidence in his profession, he had to question out loud: "I think the situation is very bad...... Once the fungus infects the brain, we can pronounce the patient dead! ”

"Young man, be calm. It's not as bad as you think! Chen Ang still said calmly and unhurriedly.

Strange jumped to his feet anxiously: "Isn't this the worst?" We sit back and watch things go for the worst, and what could be worse than that? ”

"In my surgical career, it's easy!" Chen Ang sighed: "There are many more unfortunate than it, such as the discovery of the plexus on the infected fungus, which proves that the fungus can not only make simple nerve responses, but can 'think' and carry out complex neural activities...... That's a difficult situation. ”

"It reacts more to your behavior in a more complex way."

Strange understood Chen's words, and it was precisely because he understood that he felt fear, once the fungus can carry out complex neural activities, the most optimistic situation is to be 'smarter' than a brain parasite, and they have no understanding of this fungal parasite, they don't know how it will respond to external stimuli, and they don't know what kind of stimulation related drugs will produce on it.

Strange couldn't help but break out in a cold sweat and said, "This is really a worse situation!" ”

"What's that?" Chen Ang sneered: "Don't forget, these fungi come from a highly intelligent alien race, I have prepared it to develop a complex nervous system before the operation, the better ones are only the IQ of dogs, and the worse ones can reach the level of six-year-old children like dolphins, think about it, if the fungus parasitic on the nerves has the thinking ability of a six-year-old child......"

Strange shuddered, it was an impossible operation, the operation was an extremely delicate and precise job, what doctors hated most was variables, and a six-year-old child parasitizing on the patient's nerves, it was no longer a variable - it was a disaster.

Chen Ang let the brachial plexus be more exposed in the field of vision, and sighed: "Although the fungus has a relatively advanced intelligence, it is already more tricky, but in my experiment...... No, it's not the trickiest of your surgical career. ”
