Astartes of the Bear School

Chapter 1617 1589. Strengthening Organs
To date, Lan has actually completed almost all the surgeries in the Space Marine enhancement surgery process that can directly increase combat effectiveness.

Including [Second Heart], [Bone Strengthening Organ], [Muscle Strengthening Organ], and three special surgical procedures possessed by the Primaris Space Marines.

But just like the many opponents Lan had slain in his adventuring career, powerful force is nothing more than a fortress of sand if it cannot be controlled autonomously, delicately, and skillfully.

Big but useless is an appropriate description.

The subsequent processes of Space Marine enhancement surgery are mostly used to increase the functionality and adaptability of Space Marines on the battlefield.

But it is these multifunctional auxiliary strengthening organs, coupled with the Space Marines' mature and cruel training, their profound battlefield experience, their proficient mastery of various Imperial super-technological weapons, and their technical and tactical coordination.

This is why these people, who are strictly speaking just biochemically modified humans, have the power to destroy cities and conquer the world.

The 'jump in surgical progress' that Lan En mentioned really meant a literal jump.

In a normal traditional Space Marine training process, there are a total of 19 surgical procedures. But because Lan En even manually opened his own chest to implant the most basic [Gene Seed], it was counted as an extra one for him.

His traditional Space Marine surgical procedure has twenty steps.

And including the three unique processes for original casting, there are twenty-three steps in total.

Space Marines who are normally trained by the Imperial Space Marine Chapter will be selected at around ten years old and begin the initial stages of surgery.

This lengthy surgical process usually takes nearly ten years on and off.

Because the newly added enhanced organs in the body need to adapt and overcome rejection reactions, some super organs also need time to develop and take effect in the body.

So generally speaking, when the surgery reaches the stage of implanting the [muscle strengthening organ], the body shape of a child aged twelve or thirteen is similar to that of a classical bodybuilder in Lan En's hometown world.

At this time, they will be assigned to the recruit company of the Space Marine Chapter and perform some simple and not very important tasks.

Then, while serving in the recruit company, he will carry out the remaining surgical procedures in stages until the operation is completed, the "armoring ceremony" is over, and he will be incorporated into the formal company.

But Lan En's experience is different from those of the new recruits who were trained in a procedural manner by the Empire.

He did not have a regiment as backup support, and even the [gene seed] was inserted by himself through his chest. At that time, his physical age was already eighteen, approaching nineteen.

Strangely enough, both the Demon Hunter mutation and the Space Marine surgery require the subjects to be young enough.

Lan En was an over-age subject in both biochemical transformation projects, but both were successful. I don't know if it's the so-called negative-negative-positive principle.

But even this success is only the smallest difference between Lann and a normal Space Marine.

The knowledge and skills he learned in various worlds, as well as the impact of these knowledge and skills on the body, just the [Trunk Breath] in the [Ashina Style] alone, for the correction and maintenance of body posture, has a long-term effect.

In addition, there are fighting skills, crystal cultivation technology that uses the vitality in dragon bones to break through the growth limit, Yharnam's [Acceleration Technique], the [Fire of Spells] of the Fire World, and so on.

After accumulating so much knowledge, Lann has acquired too much unique knowledge and power that normal Space Marines cannot imagine.

Therefore, because of this difference, he has confidence in what will happen next.

He planned to use the power of the Ankh Cross to complete the remaining half of the surgical procedure.

There is no example of such a thing as piling up a large number of surgical procedures at once and completing them within a narrow period of time, even in Lan En's [Memory Dive].

Because this puts too much pressure on the subject's body, the body's adaptability and rejection reaction are almost predictable.

But Lan En made a rational decision after working with his biochemical intelligent brain to deduce and calculate hundreds of times.

In fact, this decision was conservative because according to calculations, he could actually complete all the remaining surgical procedures at once.

In terms of basic physical qualities alone, there is already a clear gap between his physical condition and the average standard of Space Marines.

Even those already-formed Space Marines cannot compare to him in basic physical fitness, so of course it is no problem for him to have incomplete subsequent organ enhancements.

However, considering the current situation, this is a precious truce period in which both the North and the South have spontaneously stopped fighting due to the cold winter and logistical problems.

It was unknown when this unstable truce would be broken, and there was also the cautious planning that Lann himself and Mentos had worked out.

They decided to just finish half of the unfinished process this time.

If everything goes as smoothly as planned, then after Lann returns to this magical Middle Ages and puts an end to the Second Civil War, the rest will be easy.

Lan En pasted corresponding notes on the crystal bases of the six crystal cultivation devices to correspond to what the device would cultivate later.

Lan had already implanted the [Lariman Organ] when he came back last time. This time, he will directly advance the operation to the [Lariman Ear].

In order, the next super organ he will implant will be the [Neural Knot].

This organ is the one Cassandra saw before, the one that was implanted through a hole in the occipital bone at the back of the head and that regulates sleep rhythm.

This bean-sized tissue can regulate the brain's neural activity after being implanted.

After implanting the [Neural Knot], the subject's brain nerve activity will become more regular and under self-control, which will greatly improve the working efficiency and reaction speed of the brain nerves.

It can also 'turn off' the working areas of the brain one by one in sequence when the subject needs sleep, like taking turns on duty.

Although it cannot replace necessary sleep, it can ensure that you remain alert and observant while resting.

Next is [Pre-set Stomach].

In fact, in Lan's plan, this organ has already had the prospect of being strengthened, which is the super organ knowledge obtained from the Tyrannosaurus Rex, the Lord of the Mist Nest.

That terrifying stomach that has evolved to the point where it can even digest chaos magic and turn it into nutrition!
However, Lan En has not yet completed the research on replicating advanced spells such as [Alzu's Double Cross] and [Alzu's Multiple Triangle] through alchemical means.

One very important part of this is to use the order brought by the theory of Yin and Yang and the Five Elements to regulate the possible disorderly mutations.

This is the direction that was just established after experiencing the previous world and gaining the knowledge of Yin-Yang magic and guardian spirits. It is still immature and has not yet reached the stage of practical use.

Therefore, Lan En only plans to carry out routine implantation this time, and the subsequent "organ enhancement and super-enhancement" can be discussed later after the theory and technology are perfected.

The conventional [Pre-placed Stomach] is a large implant that fits into the chest cavity. It allows Space Marines to take toxic food that they would not otherwise be able to bear, or digest food that the original stomach cannot squeeze out of nutrition.

When necessary, the pre-placed stomach can be controlled by the recipient's extraordinary body control ability to close itself, isolating toxins that are found to be unbearable after ingestion inside the pre-placed stomach and preventing them from entering other digestive tracts.

The next step is to implant [gene detection nerves].

This is a complex operation, which is complicated and dangerous even with the technology of the human empire in the galaxy.

This enhanced organ is actually considered part of the brain, but it is actually located in the spinal cord between the cervical and thoracic vertebrae. Four special nerve sheaths are connected between the spine and the stomach wall of the [pre-placed stomach].

[Gene Detection Nerves] can give Space Marines an intelligence gathering capability that can almost be described as "evil and cruel" - by eating the flesh and blood of the enemy raw.

It can absorb genetic material produced by tissues in the body of the eaten organism that manage memory, experience, and talents through the nerve sheath connected to the [pre-stomach].

By eating a part of the enemy's body, the Space Marines can learn about the enemy's abilities and habits. If they eat the brain directly, they can get clearer memories, which are enough to be used as intelligence.

This is very useful for space warriors who need to fight back and forth between the stars and may suddenly be sent to a strange planet on an emergency mission.

Quickly learn about the local environment and the general characteristics of alien enemies you have never seen before by eating local creatures.

According to the description in [Memory Dive], this enhanced organ actually gave rise to the rituals of eating raw flesh and drinking blood among many Space Marine chapters.

Usually such war groups would be given names such as Blood Drinkers and Flesh Tearers.

This organ is also the one that Lan En focuses on strengthening.

Because it is related to the issue of whether the subsequent modified super organs in the Lann Project can be used freely.

A person cannot use an organ that did not exist before, a third hand, an extra mouth, a tail behind him, and so on, by imagination alone.

The transformation surgery for the Space Marines was developed by the Emperor and many outstanding scientists during the heyday of the Human Empire.

Each organ consumed enormous scientific research costs and efforts, and was finally finalized into today's mature surgical process.

So there is no need to worry about these organs, they can be naturally connected to the original human body control system.

But even so, the entire surgical process was stretched to nearly ten years.

But Lan En felt that given the rich and wild biological materials in the New World, there was still room for improvement in his enhanced organs.

Then these organs that are going to be strengthened in the future will not be so easy to control.
