Luo Zixuan teleported the sentry machine guns back to their original posts.

After that, the congregants were asked to burn everything unclean here. Nothing should be left behind.

The wounded are closely monitored after they are brought back. As soon as the wound showed signs of mutation, it was terminated and the body cremated.

In particular, the Medic with a broken arm must be closely monitored twenty-four hours a day for the growth of corrupt material to replace the severed limb.

Once the signs are found, they should be handled as described above.

No violation of the law to attempt any form of contact and treatment. Don't hesitate.

Even if he still retains a clear consciousness, he can't show mercy.

The people of Seon were not scientific enough to study the corroded substances of the ancient gods in a risk-free state.

Therefore, it is not possible for them to delve into these substances on their own, so as to further strengthen the understanding of the Sain's creations of the ancient gods and inspire inventions.

The greatest strength of a race that believes in science is that they can try to find inspiration from any enemy and develop equipment that has similar characteristics or can be used against them.

The individual protection device against mental contamination was created by studying spiritually contaminated creatures and nightmare creations that emitted spiritual pollution.

Luo Zixuan expects that after his strength becomes stronger, he will try to capture the ancient god creations that can cause spiritual pollution for experiments, extract the required nightmare factors and other substances, and reinvent a series of equipment and props that can help soldiers fight against the ancient god army without falling into madness and avoid corrosion to the greatest extent.

For example, the old god whispering shielding helmet, anti-psychotic pollution drugs, and so on.

The drug has gone through many iterations, and initially due to the level of technology, only a version with huge side effects and addiction to soldiers can be developed, and then the side effects began to decrease.

The last version of the Age of Annihilation has eliminated almost all adverse reactions, but it will still cause a series of damage to the kidneys when taken for a long time, and will also cause dizziness and insomnia after the effect of the drug declines.

Luo Zixuan is confident that he will develop a version with lower side effects in the future.

One of the main ingredients of this anti-psychotic drug is the nightmare factor.

As for how exactly to extract this nightmare factor?

The principle is very simple, but the practice is more complicated.

That is, let the nightmare creatures that can cause mental pollution be controlled by the restraint devices in the laboratory to affect the experimental subjects who can be mentally polluted and drive them crazy.

When the subject is driven insane, a substance is produced in the brain, named the Nightmare Factor. This substance can be extracted by extracting brain plasma, isolating it, and refining it.

If the brain extraction is done with sufficient precision, it can avoid causing the person's death. Continued injection of artificial brain plasma and closure of the wound will ensure its survival.

Often, due to the extraction of cerebral plasma and the absence of sophisticated post-operative treatment to protect memory from damage, the person will have amnesia after surgery and most of the mental pollution effect will be removed. However, there are still residues.

Subjects will go through a constant process of going crazy, extracting brain plasma, injecting artificial brain plasma, taking a short break to regain their senses, and then returning to the laboratory to continue to be mentally contaminated.

The cycle continues until it is completely insane and can no longer erase its memories by extracting brain plasma.

At this time, it is no longer possible to get more nightmare factors by extracting brain plasma. Because he will always fall into madness, but the nightmare factor is only secreted in the process of falling into madness.

Therefore, in order to make full use of the test subject, they were terminated and craniotomy, and a large amount of nightmare factors were extracted from the cortex and other materials after the brain was removed.

Then, another test subject fills his empty space.

Before the technology advanced to the point where it was possible to accurately extract a quantitative amount of brain plasma and ensure that the target did not die, and that it could be re-injected with artificial brain plasma to replace the original brain plasma function, the test subjects were all disposable.

Moreover, early technology was not enough to support the extraction of nightmare factors anywhere in the brain, and could only be extracted by extracting brain plasma. Therefore, it can be said that it is very wasteful. But the only way to protect the soldiers from fighting the Legion of the Old Gods on the front lines and avoiding the destruction of an entire civilization is not merciful.

That stupid mercy is just cold-blooded to one's own entire civilization.

Since the nightmare factor necessary for a technologically advanced civilization to fight the Old Gods is obtained, prisoners who should be executed and worthless captives who should have been disposed of are put into experimental facilities to be disposed of, so that their lives can eventually make an additional contribution.

This is a very efficient and resource-making action.

At the same time, there is nothing to be done.

If we could find an easier way to refine the Nightmare Factor, it wouldn't be so troublesome.

Some of the other three major tech tree civilizations accuse tech civilizations of being inhumane in extracting the nightmare factor in this way.

The word inhumane usually sounds ridiculous to Luo Zixuan.

There is another way to replace their tech tree, of course, they can stand and talk without backache.

Without magic, psionic powers, and the protection of genetically based gods, a technological civilization can only rely on itself.

These civilizations have endured humiliation and development along the way, not to listen to their farts. Being able to find a way to fight against the ancient gods by himself, instead of fighting spiritual pollution just by shouting two XX gods to bless him, is the most proud of Luo Zixuan.

Interstellar wars, genocide and civilizational destruction at every turn, have no mercy to speak of.

The reality is cruel, and humanity can only be applied under the premise that all survival needs can be met.

However, if you can't defeat the Old Gods, you won't survive.

Unless, some people think that the state after being corrupted by the ancient gods can still be regarded as maintaining a rational normal existence, and think that even if the entire race is waiting to be corrupted by the ancient gods, it is better than using these people to cruelly extract the nightmare factor.

If so, then Luo Zixuan also felt that there was no need to discuss this issue with him.

After all, on the premise of judging that the other party has major deficiencies in intelligence and logic, superfluous conversations are unnecessary and will only consume energy.

Some people have proposed to produce a batch of artificial humans and clones to replace those natural people as experimental subjects, thinking that this is very humane.

This proposal was pursued in the realm of certain technological civilizations in the Old Universe.

However, in Luo Zixuan's view, the logic of this proposal is problematic.

Artificial and clones can indeed be test subjects, and in the absence of prisoners and captives, it is possible to temporarily produce a batch for use in the big picture, but under normal circumstances, this is truly unnecessary cruelty.
