The demonstrator in the Raiders was the continental shelf that was detonated at the last minute before the retreat,12 although most of the Raiders tactics were implemented in the early defensive operations, but there were still some deviations in the details.

As a result, the final means of detonating the continental shelf and causing a devastating earthquake were used in advance, and 12 felt the power of a natural disaster that could be called terrifying.

The mile-style moment seismic magnitude index is 12.7, and its release energy level is nearly 400 tons of antimatter completely annihilated, while the superlight cannon energy level of the flagship-class battleship is only a kilogram-level annihilation reaction.

Comparing the two, it is no wonder that after the detonation of the continental shelf, it caused the terrifying scene of the heavens and the earth changing color and everything returning to chaos.

The entire biochemical corps in the base area, except for the biochemical beast units with the ability to fly, all other surface units were buried by the magma and liquefied surface bursting from the ground in this terrible earthquake, and it was said that the entire army was wiped out.

It's just obvious that the federal army that has adopted this kind of exhaustion has also lost its ground combat base, which means that it has basically given up control of the surface, and wants to establish a ground base with bridgehead function level again, which is almost impossible to accomplish under the obstruction of the Mythical Legion.

If you want to take down an enemy planet by relying solely on the combat landing of the space fleet, you can know the difficulty from the 12 past missions.

This means endless resource consumption, high-intensity space offensive and defensive battles and the strength of the logistics system determine the tilt of the balance of victory.

Each standard federal combat fleet is a thousand-level main sequence warship, as well as incalculable subordinate system ships, and behind it there is a logistics support system represented by a large number of resource bases.

A complete Federation main order fleet is enough to defend the entire United Star Sector, and is the representative of the highest force of the entire Federation.

And the battle of the Silver Heart War to seize the ninth-level enemy astrological area for the first time completely destroyed the three Federation Main Order fleets, and the stars that were completely destroyed on the surface environment were even more than double digits, so that the fleet numbers were all revoked, which shows the tragedy and horror of the war between the two sides.

A series of combat missions showed the true face of the war to 12, a recruit who was about to set foot on the front line, and gave him a very shocking mental stimulation.

This defensive mission finally showed the real fangs of the Biochemical Legion in front of him, and the Federation Fleet, which had lost air superiority, faced the Biochemical Legion in ground combat was so terrifying, and Shengsheng caused the Federation ground base, which had always been a near-invincible representative, to fall.

This is to say that the base guarded by 12 this time, which belongs to the third sequence of the Federation ground combat base of the Gaia-level template, covers an area of nearly 50 square kilometers, this kind of main order combat base has terrifying defensive firepower and several guard corps, and then relies on the perfect outer armor system, as well as the internal automatic maintenance system, the base fall record of each level is pitiful, and probably only the almost unsolvable war of attrition of the biochemical legion can collapse.

12 With a heavy inner mind, he gradually fell into a peaceful sleep.

His last thought was a murmur in a haze.

"Perhaps, after going to the front line, the most luxurious thing is a peaceful sleep, right?"

……

"Data on brain activity have been collected, and the state of brain tissue health has been analyzed as follows...... It is recommended to combine the following medications for deep repair again. ”

The medical host that monitored Su Zhao's brain health gave a series of suggestions, and then Luo Shen repeatedly analyzed and decided.

After the last long-term dormant brain tissue repair, through the detection of Su Zhao's brain activity this time, a more detailed medical plan needs to be carried out again.

In fact, the damage caused to Su Zhao's brain by the autolysis of brain tissue was too great, although it was only a short moment, but it was also almost devastating for a fully mature adult brain.

The reason why Su Zhao didn't feel these was because his brain function was basically intact after Luo Shen's repair, and at the same time, the continuous single-player combat missions deliberately avoided the damaged area to be mobilized for personnel exchanges and conversations.

At the same time, in order to repair and complete the function of the brain region, Su Zhao relied on Luo Shen's help to maintain it, coupled with the characteristics of dreams, so that Su Zhao in the virtual world basically behaved normally.

"Start the fourth stage of brain repair, after this repair is completed, Su Zhao's brain should basically return to normal, and it can also liberate me a lot of computing power."

Luo Shen watched Su Zhao in the hibernation cabin quickly go through the eye movement period and enter a deep sleep, and under the precise dosing effect of the medical host, he entered Su Zhao's brain by the nano medical robot to carry out extremely detailed directional tissue repair tasks.

"Estimated mission time, 276 hours ......"

Due to the nature of the delicate task, the time required for this medical task is slightly lengthy because it requires the complete process of cell differentiation and maturation in biological tissues.

And in such a long time, Roselle and Hela can go on another important mission.

"Sister Roselle! The first stage of the melt-through system is complete! Now the second phase of equipment installation is underway, and we will be ready for commissioning in 21 hours. ”

Little Hella soon brought good news to Roselle, and after her continuous and serious work, the first phase of work, including the renovation and reinforcement of cable equipment and underground passages, has been basically completed, and now it is time to carry out the process of laying cables and installing equipment.

After more than a dozen hours of busy work, a large number of equipment that was synchronized with production and transportation was transported to the underground mine for installation, and the pulsed dimmed laser meltdown cannon on the Sirius was also transported to the underground world by the transport plane, where it was being installed and commissioned.

Moving to the underworld, an optimized passage has been laid with transport rails, and the production of these rails is extremely simple for the little Hela, which has several high-abundance iron ores, and after her vacuum soaking furnace is put into operation, the steel production capacity of the entire outpost is more than enough to cope with the production of these dozens of kilometers of rails.

The melt penetrator is transported at high speed through a busy underground track to the fracture entrance of the underground geosphere.

Cracks in Qingshan rock mass, and related transformation work is still ongoing.

The width of this huge crack does not need to be considered, but the depth is too large, and it is necessary for Xiaohella to establish a complete support structure, so that the relevant equipment can be transported to the end of the crack for melt-through work.

The current melt penetration machine can just carry out some renovation work along the cracks, smooth some protruding rocks blocking the route, and also check the working state of the melt penetration machine.

"The energy supply system has been put online, and the line is being tested...... The power supply line is normal, and the first load test is carried out. ”

"Communication system connected, channel status, good, transmission bandwidth test ......"

With the help of the little Hela's spider mech, the thick cable was successfully connected to the melt penetration machine, and the outer layer of heat insulation armor was also installed by the robot simultaneously.

"The melt-through machine is running on, the self-test of the cooling system is normal, the first load test begins, and the preset power level is low."

The melt-through machine, which is made of a pulse-modulated laser cannon with titanium-sapphire as the continuous excitation source, finally starts to work under a series of commands, and after a short charge at the transmitter end, an extremely condensed blue-white high-energy laser is released, which is irradiated on the hard Qingshan rock mass.

With the work of the melt-through machine, the four-unit fission reaction unit responsible for the function on the ground quickly entered the working state, and the extremely powerful electrical energy went deep into the ground along the silver-copper alloy cable with extremely high conductivity efficiency and went directly to the melt-through machine.

The conditions are limited, and the superconducting material power supply cable used in the starship reactor Xiao Hela cannot be mass-produced for the time being, and the fission unit on the surface is already the result of her best efforts, so the power supply cable can only have the existing processing capacity to produce silver-copper alloy cables.

A large number of transformers in the entire power supply line, the voltage stabilizing filter device began to enter the working state, and the heat dissipation system of related equipment began to run rapidly to combat the already very hot and high temperature environment of the underground world.

Since there is a fission power station, it is reasonable to use the large air volume ducted fan to supply relatively low air to the underground, and the ducted fan covered with huge mountain cracks began to run at full strength, making a terrifying whistling sound, forming a typhoon-level super air volume and higher wind speed.

The underground transportation channel has formed a relatively sealed environment through simple engineering, and with the help of air pressure difference, the hot air in the underground transportation channel can be pushed into those unclosed fork passages.

"It seems that in the later stage, it is necessary to renovate a liquid-cooled heat dissipation pipe for the underground passage, which is too inefficient."

After a simple calculation of the heat exchange efficiency value, Xiao Hella came to the conclusion that her current complete set of heat dissipation solutions supports the melt-through machine to work at medium power at most, if the power is high, the heat dissipation requirements of the power supply equipment will not be able to keep up, and those node power equipment is easy to overheat and melt.

After all, this power supply line provides thousands of kilovolts of ultra-high voltage and high current, and provides the highest power output of the 100 megawatts of the melt-through machine.

Hella made a rough rehearsal of the relevant renovation plan for the liquid cooling system, and then arranged the relevant preparations into the current activities.

At present, it is mainly to collect the working data of the melt penetration machine, so as to carry out relevant optimization and debugging according to the actual working state.

The characteristics of the hard Qingshan rock mass are similar to alloys, so that the internal metal atoms quickly enter the state of electron excitation after absorbing the ultra-high energy transfer from the laser pulse, and the orbital electrons quickly jump after acquiring enough energy to release saturated energy photons.

The external manifestation is that the irradiated rock mass heats up and melts rapidly, and the bottom of the crack flows away under the action of gravity.

The part directly irradiated by the pulsed laser, due to the hysteresis of high-energy transmission, the supersaturated high-energy state makes the rock mass directly sublimated from the solid state, and a small number even directly enters the plasma state of the highest energy level, a large amount of metal vapor and dazzling flame light are lit up, and it is not a burst sound of gas expansion.

"Melt-through velocity is recorded, adjusting the optimal rate of movement at the irradiation angle."

Based on the current working efficiency of the melt-through, Heller quickly calculates the optimal feed and orbit angle, so that the pulsed laser beam of the melt-through machine slowly changes the foreground at a circular illumination angle and corrects the channel in front to an approximate circle.

After working in low-power mode for an hour, Heller, combined with the working parameters of the entire system during the period, confirmed that the underground tunnel meltthrough system was working properly.

"Fuse Penetrator Power Mode Adjustment: Medium."

After receiving the instruction, the titanium sapphire excitation array inside the melt-through machine called more units into the working mode, and the brightness and diameter of the pulsed laser released were significantly increased by a grade, and the forward rate was also significantly improved.

In the past, the front end of the melt pass machine was continuously irradiated, and with the feed of the body of the melt pass machine, the correction efficiency of the channel was rapidly improved.

"Estimated time to arrive at the job site: 11 hours, the power supply system is running in a good state."

Little Hela used the wind speed sensor to feel the air flow inside the tunnel, looked at the hot molten metal that splashed on the body of the melter from time to time, and after calculating the working hours, she left the place and returned to the crystal mine to continue her mining mission.

"Start calculating the liquid cooling system retrofit!"

The Hella host on the Sirius, using the idle computing power at the moment, immediately began to calculate the liquid-cooled modification plan.

And Luo Shen began to think about his next task for Su Zhao.

"How can you enter a real battlefield, such a battlefield simulation dawn crew can't bear it."

"Then, it's time to find a way to bring you back to reality, and the exploration of the ruins may require your help."

It was still a familiar scene, Luo Shen stood in front of Su Zhao's dormant warehouse, planning the fate of this human being.
