The six tests organized by Howard can only be regarded as a warm-up exercise before the establishment of the Doomsday Force.

Ten special forces will officially join the Doomsday Force only after completing the system modulation and obtaining their own Doomsday Warrior system.

For the sake of safety, the modulation of the Doomsday Warrior system is handled by the scientific advisors of the respective countries.

It's just that there is only one set of equipment for modulation, and ten special forces have to do it in order. Although Aldrich has been designated by Howard as the leader of the Doomsday Force, this appointment will not take effect until the Doomsday Force is officially established, that is, the doomsday soldier system of the ten special forces is modulated. According to Howard's arrangement, Chu Tianjiang will become the first "Doomsday Warrior", and then Aldrich.

"Damn, isn't that making me a guinea pig?" Chu Tianjiang was very unhappy. Howard said it nicely, he tied with Aldrich for first place overall, but he didn't become the captain of the Doomsday Force, not even the vice-captain, and deserved the honor of being the first "Doomsday Warrior".

There is no honor at all, there is only the risk of being the first to eat crabs.

When Luo Jinyong was having lunch, Chu Tianjiang asked a few questions that he had wanted to ask for a long time, but had never had a chance to ask, such as why there were only ten sets of doomsday warrior systems for Lang.

If the Doomsday Force is the hope of humanity, then the size of this force should be as large as possible.

Luo Jinyong mentioned two factors, one is funding, and the other is personnel allocation.

From the start of the project to the completion of the manufacturing of the 10 Doomsday Warrior systems, the Council for Planetary Defense has invested $240 billion in the project over the past two years. If you include the cost of supporting equipment, the total investment of the project is more than 400 billion US dollars.

Although the total cost of projects shared by the 10 member states in the past two years amounted to $2.5 trillion, and only 16 percent of the doomsday force project was spent, the doomsday force spent on hundreds of scientific research projects and defense projects, second only to the Doomsday force in spending on the operation courage project.

The enormous cost of the Planetary Defense Council has long been too much for the ten member states to bear.

In China, for example, it has spent a total of $375 billion on 15 percent of its voting rights, while China's average annual defense spending over the past two years has been only $180 billion. If this money is included in the fiscal expenditure, it is not a big problem. China's fiscal spending in the past two years has exceeded $3 trillion. The problem is that, for the sake of secrecy, this money cannot be justifiably included in the fiscal expenditure.

In other countries, the same problem exists.

Even the United States, which has deep pockets, can only use all kinds of shady means to squeeze $1.5 trillion out of federal spending.

It's just that funding is definitely not the main reason for limiting the size of Doomsday forces.

Of the $240 billion directly invested, $200 billion was spent on preliminary research and technical development, and only $40 billion was spent on the production of ten sets of Doomsday Warrior systems, including the establishment of production lines for various subsystems, so the cost of increasing production was not large.

According to Luo Jinyong's estimates, without counting other inputs, the unit price of the Doomsday Warrior system can be controlled within one billion US dollars, and it will definitely not exceed two billion US dollars. With the financial resources of ten countries, it is definitely not a problem to expand the Doomsday Force to a hundred.

The key is staffing.

The reason is very simple, if the size of the Doomsday Force is 100 people, the United States will definitely demand that the quota be allocated according to voting rights, or investment proportions. The United States will occupy 60 places in the Doomsday Force, China will have 15, Russia, Britain, and France will have five each, Japan and Germany will have three each, and Israel, Canada, and Australia will have a total of four. As a result, the Doomsday Force became the "private arm" of the United States.

A similar situation would occur if the size of the Doomsday Force were doubled to twenty.

On the contrary, the United States could only be prevented from controlling the Doomsday Force by limiting the size to 10 troops, with individual soldiers as the basic unit and 10 member states having to be taken care of.

For this reason, China and Russia have repeatedly used withdrawal as a threat to force the United States to make concessions.

However, China and Russia have also made concessions on relevant issues. That is, if the actual combat proves that the Doomsday Force is the only military force that can resist the invasion of extraterrestrial civilizations, the production techniques of the Doomsday Warrior system will be fully disclosed, and all ten member states have the right to form their own Doomsday Force.

The situation has developed to this point, and it no longer matters whose Doomsday forces are larger.

Due to the fact that the Doomsday Warrior system is severely limited in production and can only have one user per system, no system-wide testing has been done before the Doom Force is officially equipped. The first special forces to put on the Doomsday Warrior system took the biggest risk.

"Lao Chu, are you shaking?"

"Shivering?" Chu Tianjiang glanced back at Zhang Xiaogang.

"Don't be afraid, I'm here." Luo Jinyong tried to squeeze out a smile and said, "Remember what I started to say, but don't show it." ”

"Professor, are you sure?"

"Not at all, but 99 percent." Luo Jinyong is a rigorous scientist. "Comparatively speaking, modulation failure is a small probability event."

"Professor, you're not right." Zhang Xiaogang caught up with Chu Tianjiang's pace and said, "Old Chu, you can rest assured and go boldly." You must know that if the concoction fails, the only hope of mankind will be completely destroyed. In less than a month, we'll meet in the Netherworld. ”

Chu Tianjiang rolled his eyes, but Zhang Xiaogang was right.

"When you see Lord Yama, remember to intercede for our brothers who arrived later, let black and white impermanence be gentle when asking for life, and don't let us suffer too much. Before I go to you, I'm sure I'll burn a few wagons of Dead Coins and dozens of beauties to keep us fed and clothed in the Netherworld, and a horde of female ghosts waiting. and then buy off Lord Yama and get a half-official position. Those days must have been much more comfortable than enduring hardships in the world. ”

"Fuck your fart."

"Ha Lu Ha ......" Zhang Xiaogang smiled and patted his shoulder, stopping outside the modulation center.

Luo Jinyong followed, and he personally concocted the Doomsday Warrior System for Chu Tianjiang.

The preparation takes place in a transparent container filled with a viscous transparent liquid. To be precise, this is a zero-gravity space created by a strong magnetic field. The density of the liquid is the same as that of the human body, and after Chu Tianjiang entered, the buoyancy canceled out the gravity, which was equivalent to being suspended in mid-air.

Because he didn't wear a breathing mask, Chu Tianjiang was a little uncomfortable at first.

The main component of the fluid is an oxygen-rich fluid substance similar to amniotic fluid, which directly sends oxygen to the lungs, allowing Chu Tianjiang to breathe normally. However, the density and viscosity of fluid matter are higher than that of air, and even with higher oxygen content, breathing is much more difficult than usual.

It took a few minutes for Chu Tianjiang to get used to his new way of breathing.

The solution is simple, reduce the respiratory rate from 10 to 1 breath per minute, allowing the oxygenated fluid to stay in the lungs for a longer period of time.

"Lao Chu, are you ready? If yes, blink your right eye, otherwise blink your left eye. ”

Chu Tianjiang blinked his right eye. He could breathe, but he couldn't speak.

The liquid had filled Chu Tianjiang's respiratory tract and digestive tract, and the food and digestive products in the digestive tract were being discharged, and some internal parasites were also discharged. After only a few seconds, the filth is completely decomposed and emitted from the poles at the bottom that confine the magnetic field.

"Now, let's start the first step, nervous system modulation."

Chu Tianjiang blinked his right eye again.

Luo Jinyong gave a comprehensive introduction to the modulation process, first of all, the nervous system modulation, that is, to combine Chu Tianjiang's nervous system with the nerve center control system of the Doomsday Warrior, so that Chu Tianjiang could control the Doomsday Warrior system through thinking and simple body movements.

A robotic arm reached into the liquid and injected Chu Tianjiang with an anesthetic that directly acted on the sensory nervous system.

When the anesthetic began to take effect, Chu Tianjiang was left with only sight and hearing, and his sense of smell, taste, and most importantly, touch were all closed.

In this case, even if he was dismantled, Chu Tianjiang would not have the slightest pain.

At this time, on Chu Tianjiang's back, along his spine, twenty-four black spots the size of soybeans appeared. A nanobot so small that it is invisible to the naked eye is drilling open the twenty-four vertebrae of Chu Tianjiang, exposing the spinal nerves, and quickly repairing the wound section without blood flowing out.

If the human brain is the central processing unit, then the spinal nervous system is the data transmission bus.

The brain's instructions to various parts of the body, and the feedback of tactile signals from various parts of the body to the brain, all have to pass through the spinal nerves.

The nerve center control system developed by Luo Jinyong is directly connected to the spinal nerves.

How did it happen, only Luo Jinyong knew it.

It is precisely because of the lack of relevant technology that the United States cannot manufacture the Doomsday Warrior system alone, at least not the Doomsday Warrior system with the nerve center control system as the core.

The whole process lasted about half an hour, and the nanobot repaired the wound on Chu Tianjiang's spine.

After repairing his muscles and skin, Chu Tianjiang's spine had twenty-four more ports the size of a round coin. When using the Doomsday Warrior system, the central control system will connect with the nerves in his spine through these ports to receive instructions for action from the brain.

The ports are black and look like metal, but it's not that simple.

According to Luo Jinyong's introduction, the material used to make the port is nano-scale silica fiber, that is, glass fiber. Each port is made up of hundreds of millions of fibers, making up tens of millions of haptic transmission lines, each of which is made up of ten fibers and backs up each other. Even so, the tactile control subsystem of the central nervous system has only one billion transmission lines, which is only 1/10,000th of the human tactile nerve endings.

"Now, let's move on to the second step, sensory system modulation."

Chu Tianjiang blinked his right eye, then closed it. After only a few seconds, the eyelids of both eyes were forcibly discerned by an external force.

Something entered his eye socket, Chu Tianjiang wanted to blink, but his eyelids couldn't move at all.

Stimulated, the lacrimal glands begin to secrete tears.

The whole process lasted about half a minute, and when the nanobot cleaned up the tears, Chu Tianjiang found that his vision was several times higher than before.

Luo Jinyong really didn't brag, and did do something in the concoction.

According to the normal procedure, sensory system modulation only establishes a connection with the visual, auditory, olfactory and gustatory nervous systems. Because these four senses are directly connected to the brain, not through the spinal nerves, and are more important than the sense of touch, they have to be modulated separately.

On Chu Tianjiang, Luo Jinyong did more, that is, to improve the sharpness of these four senses when concocting.

Next, Chu Tianjiang found that his hearing had also been greatly enhanced, and he could hear the sound of electricity emitted when the machine was running, and even the footsteps of scientific researchers walking outside the room.

The changes in his sense of smell and taste were also very large, but Chu Tianjiang couldn't feel it, because the liquid wrapped around him had no taste.

"Lao Chu, the modulation of the nerve center control system has been completed, and now it is equipped with other subsystems, you have to cooperate with me."

Chu Tianjiang blinked, and the external force exerted on his eyelids had disappeared.

Because the other subsystems were mainly developed by the United States, Luo Jinyong couldn't do anything, he could only ensure that the subsystems assigned to Chu Tianjiang could work normally.

The entire setup and concoction lasted an hour and a half, all carried out by nanobots in the liquid.
