Fish is characterized by its smooth and creamy texture, but in terms of the eating experience, it cannot compare with beef.

"Cheers!" The heavy drinker, the Iron-Eating Beast, raised his glass, and everyone except Rosemary followed suit. "Cheers!"

"This is the last time we'll all get together. I know some of you are going to transfer to the military's arts troupe, some are going to transfer to the news team, and some are studying for the college entrance exam. But at least today, we can still have a good get-together. Remember to come back and visit me when you've made it big!"

These young actors each have their own paths to take. Some want to take their careers to the next level and don't want to spend their lives entertaining others with their looks. They are studying and taking exams to prepare for further education.

Some decided to go to the front lines to record the truth and the brutal battlefield with their cameras;

Some planned to pursue artistic careers within the military, bringing joy to those fighting on the front lines, although most of the time they were stationed in the rear of occupied territories to alleviate the anxieties of the civilians.

However, Rosemary and Iron Eater will not leave. One is due to health reasons, and the other has considered joining the army. After all, she is a martial artist. However, the mode of modern warfare has rendered personal combat power quickly obsolete.

Destroying a city used to be a symbol of the pinnacle of personal power, but now any Titan can destroy a city that once existed with a single shot.

So after realizing that his iron fists were useless on the battlefield, Iron Eater settled down to his acting career.

Using fists and using art are the same thing; for her, she hopes to convey the fighting spirit of martial artists and promote justice, not violence. Frankly, using fists is actually more effective now than in the past.

[PS]

How big could early towns be? By this standard, a Witch-king capable of remotely destroying a small town would be at most equivalent to a few modern 155mm guns. Considering Terra's unique characteristics, with its overly concentrated urban structure, they might actually be even smaller.

Many people, upon seeing the destructive power of a city-destroying force, immediately compare it to modern metropolitan areas with populations of millions, equating it with the destructive power of a nuclear bomb. However, considering the historical context… that level of destructive power is actually quite insignificant.

If we consider that Terra's building materials are all flammable, lightweight carbon materials, similar to the bamboo and wood structures used in Japan, then let alone the firepower of Sister Tako, even if you gave me a can of gasoline and a torch, I would still be a city-destroying witch king—burning the whole city down with a single fire would be no problem, as the doujinshi has already proven.

When you use carbon materials or similar flammable materials as building materials, you can destroy a city in one blow with just a barrel of gasoline.

Similarly, the same applies to the army; in that era, three fully armed knights could chase down and kill thousands of peasant soldiers.

If these knights' physical abilities are based on Terran standards, which are about three times that of humans, and if we also consider Originium Arts and possible relics of the ancients, then the combat power of the Breaking Army-class is just so-so.

【PS2】Rosemary's breed is actually a Ragdoll cat..._(:з」∠)_, but it is quite fitting. Ragdoll cats are artificially bred cats with extremely docile and affectionate personalities. Moreover, because they are artificially bred, they are very delicate and prone to illness.

Additionally, if that's the case, then Rosemary should have the characteristics of a Ragdoll cat—it becomes limp and powerless once it's picked up or lifted.

Chapter Seventy-Six: Surgery and Longevity

Chapter 76

"Is this all?" The little cat, dressed in surgical scrubs, looked at the torture apparatus in the room. "What do I have to do?"

"Sit on it, it will hurt a lot, but don't move around." Xia Lin was adjusting the medical surgical equipment that she had taken from the Windrunner.

Neurosurgery is not within the scope of veterinary medicine at all, because livestock do not require it.

That's why Rosemary's surgery was delayed until today, because the surgeon needed to spend a lot of time practicing with pig brains.

"Heave-ho!" The kitten climbed onto the medical bed and sat in the groove. The automatic locking mechanism popped out instantly, fixing her limbs in place. With a slight sound of mechanical movement, the support for her neck lifted slightly, and the scorpion-tail-like curved mechanical arm unfolded, with the sharp needle tip less than a centimeter away from her head.

"Dr. Keshield said to shave my head, but I didn't. Why?" Xia Lin looked curiously at the unfamiliar tools she was fiddling with, her big blue-purple eyes filled with curiosity.

"Yes, two of the three surgical options require shaving and cutting the skin, but one does not."

One special form of Star Alliance surgery involves injecting a certain amount of nanofluid into the patient. By controlling the movement of the needle at a height of about 5 millimeters above the ground, the fluid below is controlled to directly penetrate through the vascular network and muscle groups, moving slowly to the lesion area like water flowing through a filter.

Subsequently, under signal stimulation, they transform into countless controllable, tiny suspended blades to destroy the target cells. This surgical approach is typically used for tumors, i.e., cancer, to precisely destroy and inhibit the spread of cancer cells.

Symbionts do not allow the destruction of cells that produce disease in the human body, in order to avoid triggering an immune storm based on the symbiont due to misidentification.

At the same time, this surgical method is also used in certain specific environments, such as microgravity environments, where there is no need for significant bleeding and it is necessary to prevent large-scale damage to blood vessels. The operation is extremely difficult.

After all, doctors can't see what's underneath; they can only use equipment and instruments to determine the order and path of the incision.

Xia Lin doesn't use this technique to perform surgery; he doesn't have that ability. If he did, he could at least be promoted to associate chief physician. Besides, neurosurgery is not included in regular veterinary training.

Instead, this fluidic blade creates an implantation channel without cutting open the brain and damaging the rosemary brain tissue. In the non-cutting blade mode, the fluid, like a small molecule liquid, quickly penetrates the blood-brain barrier and various blood vessels without causing harm.

During this process, patients will feel swelling and heat in some parts of their body. Even when the surgery begins, there will be little pain, only a slight burning pain, which greatly reduces the surgical damage and postoperative recovery time for patients.

"Get ready, I'm about to start..." Xia Lin brought over a rather intimidating needle and attached it to a flexible tube under the bed. "Bear the pain, I'm about to sever your nerve signal system..."

The nerve block needle was inserted through the spine, and the instantaneous extreme pain made the kitten tremble. The strong restraint ring made it difficult for her to move her limbs to break free, but she quickly calmed down.

"It hurts so much..."

"Hmm, but it only hurts for a moment." Xia Lin brushed aside her hair and found the artery on her slender, fair neck. He inserted the needle, which was protected in a sterile sheath, into it, and then a pale white, slightly reddish fluid was slowly injected into the artery.

"Surgery initiated." PNIS connected to the operating table, and the laser mesh stretched out countless fine grids on her scalp. Then the scanning and imaging systems began to work. The shadow formed by the fluid scalpel moved along the blood circulation in her body, gradually entering the brain and then seeping across the blood-brain barrier, wrapping around the outer layer of the meninges like a thin film.

The memory implant is not large, only about 3 millimeters in size. A small hole is drilled in the skull, the implant is inserted, and then a fluidic scalpel wraps around it and seals the wound. The rest is handled by the symbiont that is injected once.

"This is it." After searching for a long time, the kitten finally found the location of the memory. Because the pain signal was cut off, the kitten could only stare blankly at the ceiling and could not feel anything.

The fluid scalpel quickly penetrated the skull, muscles, fat, and skin from the inside out, creating a small bulge at the Rosemary side of the brain. The bulge was then cut open with a needle, and the implant was placed into the fluid. The suturing process then began.

Next, the fluidic blade will envelop the implant and travel directly to the implantation point. Once in place, Xia Lin will activate the remote implant working mode, which will automatically connect to the symbiote and then construct a brain-computer interface channel.

This part is almost foolproof, but even so, it seems that Lao Xia still messed it up a bit. Fortunately, it doesn't affect actual use. At most, it might affect the blood vessels in the brain and induce future sequelae such as cerebral infarction and migraine.

Placing it in the Covenant would probably be a medical malpractice case, but placing it here, these side effects aren't a big problem, as long as the subsequent neural bridging isn't connected incorrectly either.

Just watching the surgeon hold the instruction manual in one hand and the controller in the other is enough to instill great distrust and fear in the patient.

However, perhaps due to good luck, or perhaps because the foolproof design was indeed effective, the neural bridging project was successfully completed.

The next step is to build a brain-computer interface. Compared to the cat, it has an additional hippocampus, but unfortunately, it requires manual operation.

If automatic memory backup is required, then unless Lao Xia obtains a formal license and reaches the level of associate chief physician, he can perform such a complex surgical procedure. Manual backup is much simpler.

Because it only needs to connect a very small number of neurons, it does not require processing of the brain's neural structure.

The difference between this device and the terminal that Lao Xia usually uses is that the chip is placed inside the skull and operated indirectly through the neural link of the symbiote. The biggest cost of upgrading the brain implant in the Star Alliance is the surgery fee; the device itself is not expensive.

"Withdraw the discarded fluid blade, and the symbiote plugs the wound..." The final step is to remove the blade. This surgical method is costly and difficult, but it has the least impact and harm on the patient.

"Detection Usage Mode" A faint light appeared in the kitten's eyes, indicating that the symbiote was taking effect, directly transmitting information to the retina and optic nerve. "What's next?"

"Select memory backup, contextual memory section..." Program memory does not require backup.

"and then?"

"Then just leave it alone."

The working principle of this memory is very simple. It doesn't read and store human brain memories. That kind of equipment is not only extremely expensive, but the surgery is also too difficult for a quack like Lao Xia, who practices on pig brains while reading the instructions.

Instead, once activated, all of the kitten's subjective bodily sensations and some hormonal information will be recorded until the storage is full. After she loses her memory, she only needs to activate the recovery mode, and this recorded information will be quickly fed back into the brain's sensory area in the form of electrical signals.

Essentially, it's about letting her relive the memories and experiences of that period in a very short time. During the process, she will experience headaches, dizziness, and a state of disorientation. Once the new memories are overwritten, she will remember the parts she had forgotten.

As for whether it will overwrite some of the new memories, that's not something Lao Xia can judge or handle—don't have too much hope for the veterinarian.

"Considering your hyperthymesia, I suggest you only turn it on when you feel you absolutely need to remember something, and turn it off the rest of the time. This way, the amount of information you need to access at once will be much smaller. Also, hyperthymesia causes you to remember a lot of unnecessary things, and turning this feature on can actually filter out that irrelevant and messy information, allowing your memory to return to a normal level. However, I dare not implement that function..."

With Lao Xia's skills, it's almost a 100% medical accident. Please go to a top-tier hospital in the inner ring road and find a chief physician or professor to perform the surgery. A quack doctor is bound to cause problems.

Especially considering this quack doctor only studied instruction manuals and pig brains—and became familiar with them by sending away seven or eight pigs a week.

“That’s already great…” the kitten said happily. “At least this way I can remember my friends’ names instead of having to look in a notebook.”

Her procedural memory did not seem to be greatly affected. For example, the skills she learned, some common knowledge she learned, the words she learned, her writing habits, her eating habits, etc., which are based on muscle memory and deep memory, were not affected.

However, episodic narrative memory is severely affected. After all, this function seems unnecessary for organisms, so whenever memories overflow, the brain first deletes that part to make room.

"You'd better observe for a while. If there's a problem... well, I can't handle it if there is." Old Xia could only say that he couldn't do anything about the problem, since this equipment was for proper doctors, not for veterinarians like him.

"Thanks……"

"No need, just hope you won't stick voodoo dolls on me at night anymore..."

With a surgical outcome like this, if it were in the Star Alliance, the patient's family would absolutely have to sue him until he was bankrupt.

Of course, it's more likely that he'll have to go to jail for practicing medicine without a license before the patient's family can file a lawsuit.

"Also, the symbiote can significantly extend lifespan, but there are limits, and you injected a simplified version, so the effect is very limited. Therefore, it's best to conserve your brainpower, otherwise the symbiote won't be able to repair itself." Although all the parameters were within the acceptable range, Lao Xia wasn't confident in his skills and wanted to reduce the workload as much as possible.

"Was the surgery successful?" Kal'tsit asked as she saw the kitten come out carrying its notebook.

"Ok!"

"It's probably, maybe, perhaps, or you could say...it's a success." The doctor and patient had completely opposite attitudes; the patient seemed very happy, while the doctor looked anxious.

"Huh? Success is success. What do you mean by 'probably successful'?" Compared to a certain veterinarian, Kal'tsit is a real doctor.

Moreover, she has excellent skills, but she simply cannot use the official Star Alliance equipment instead of being the one doing it.

"The basic purpose has been achieved, but there may be side effects and aftereffects, and I cannot guarantee how long it will be effective."

"That means the surgery failed." What's the difference between that and curing the disease and then killing the patient as well?

"In short, that's it. The only thing we can guarantee is that she'll live at least a little longer than she did before..."

Such repeated amnesia and rewriting can easily lead to problems, and the high activity of neural memory cells can increase the risk of cancer.

It's possible that Rosemary's amnesia is partly due to this, in addition to her hyperthymesia.

Being too active can cause the immune system to mistakenly identify them as cancer cells and destroy them immediately—this characteristic of hair matrix cells is part of the reason for hair loss.

"Hmm, what...problems are there with repeatedly overwriting memories?" Kal'tsit's instincts as a medical professional made her realize that there might be some theories or experimental results she was unaware of.

"Besides an increased risk of cancer, there's a chance of... well, a disconnect between the mind and body..."

"Tell me more!" Kai Maomao poured Lao Xia a cup of coffee, looking very interested.

"You study this?"

"Hmm, I've done some research on that..."

"Speaking of which, don't you have this problem?" Old Xia looked at Kai Maomao. "I remember they said you are an immortal. Don't you have this condition?"

"What?" Kal'tsit didn't understand why this topic had been brought up to her.

"Well... we have also conducted research on immortality or longevity. To be honest, our technology is more advanced. You know, we can even perform somatic cell genetic reconstruction and repair and cell recombination, restore cell lifespan and correct coordination. Theoretically, without considering the cost, we can maintain a person's immortality."

The Covenant did indeed do such things. This series of biotechnologies initially emerged to serve this purpose, as human greed for life surpasses all other greed.

"The results of it?"

"The result is that the earliest experimenter is still alive. He is probably over 100 years old and has not deviated from our normal lifespan." Theoretically, the Covenant has an average lifespan of about 200 years.

However, so far there has been no phenomenon of them dying of old age—after all, it has only been a few decades since this series of technologies came into existence.

“But the problem is, our measures to prevent him from aging have already failed before he even reached his normal lifespan limit.” Xia Lin thought for a moment. “In other words, people who have undergone this kind of immortality or longevity treatment die faster than normal people in a sense…”

"What did you do?" Keshir was also a little horrified. Old Xia was telling a story, and most of the people in the Covenant were still far from dying of old age (it was only the mid-to-late 22nd century, and the oldest test subject was just over 100 years old). But she was a genuine immortal, and since it concerned her own life and death, she couldn't help but care.
