When Han Feng carried Wu Yuli out of the Unimog RV, a clock with a 60-minute countdown appeared in his mind, and on the dial of the clock, the red hands were still turning backwards 'tick, tick'.

And Han Feng, who already had the experience of the last promotion, stood quietly next to the Unimog RV, watching the changes in the RV.

However, the evolution of the mechanical core does not seem to have affected the appearance of the Unimog RV.

At this moment, the Unimog RV still maintains a body of nearly nine meters, and all the parts of the RV seem to remain the same as they were, without any changes.

As time slowly passed, when the sixty-minute countdown clock in Han Feng's mind returned to zero, the electronic voice of the mechanical core announced that the upgrade had been completed, and a hologram of the Unimog RV also appeared in his mind again.

This time, the process of the mechanical core advancing to gold didn't feel anything for Han Feng, and the whole process seemed extremely bland, without even a trace of waves.

Although the mechanical core upgrade process was unusually calm this time, Han Feng still opened the details of the Unimog RV and began to observe, and the lines of data entered his mind.

Model: Unimog U4000 RV

Brand: This time

Power: Nuclear-powered

Engine: /2 engine

Fuel tank: N/A

Water tank: 200L

Special Mode 1: Battle Castle Mode, in Battle Castle Mode, the vehicle cannot move, and the space energy absorber at the vehicle chassis position will be activated, absorbing free energy in all dimensions for the mechanical core to call, in this state, the vehicle will not be limited by energy, and the recharge speed of the energy shield system will be increased by 1000%.

The time limit for the activation of the battle fort mode is 1 hour, after which the space energy absorber will automatically stop working, and it can only be activated again after 24 hours of cooldown.

Special mode 2: vehicle garrison mode, in the garrison mode, the vehicle will be expanded through the space folding module to become a fixed building covering an area of 1,000 square meters, while the energy module, attack module, and defense module will inherit the original attributes of the vehicle, and the mobile function will be canceled, and the conversion time of each garrison and deployment shall not be less than 24 hours.

Mechanical core fusion transformation system:

Main Weapon System: The Celestial Punishment Particle Plasma Cannon, which invokes 40% of the energy in the miniature nuclear reactor with each firing, and sends out a stream of high-energy particles to bombard the target, causing a wide area of damage.

Secondary weapon system: 75mm microwave laser automatic rapid-fire gun X4

External Weapon System: General-purpose Ship Chopper

Protection system: The shell is alloy armor, approximately equal to 500 mm of homogeneous armor, with an additional 1200 mm of external superalloy armor coating, and the total armor thickness is approximately equal to 1700 mm of homogeneous armor.

Energy protection system: Standard energy shield system, energy shield strength is 42,000 kJ, energy shield backflush time is one hour.

Reconnaissance system: Seeker unmanned reconnaissance aircraft system, which can launch UAVs for over-the-horizon reconnaissance.

Special system 1: 20 cubic meters of on-board super-dimensional space.

Special system 2: automatic flotation device, the vehicle can float forward on the water surface, when floating on the water surface, the speed is 25% of the speed on land:

Special System 3: Equipment Manufacturing System, in addition to vehicle-mounted equipment, can currently manufacture three types of individual equipment, namely the 'Cutter' laser sword, the 'Bastion' tactical shield and the 'Peregrine Falcon' jetpack.

After reading all the information of the Unimog RV one by one, Han Feng finally breathed a sigh of relief.

The evolutionary content of this article has been accumulated step by step with great effort.

However, what Han Feng paid the most attention to was the new mode obtained after the mechanical core was promoted to gold this time-Battle Castle mode.

After seeing this model, Han Feng's first thought was that this model was completely a model that would become a beneficiary if it didn't succeed.

The Unimog motorhome pays the price of not being able to move in exchange for an hour of unlimited energy.

In this hour, the Heavenly Punishment Particle Plasma Cannon and four 75mm microwave laser automatic rapid-fire guns can fire infinitely, splashing terrifying firepower to the fullest.

And at the same time, because the energy shield system will also get a 1000% bonus to the shield recharge speed in Warburg mode, the Unimog RV can use the energy shield to resist incoming fire while desperately splashing firepower.

Therefore, the Unimog RV in the battle fort mode completely adheres to one concept, that is, don't be cowardly, just do it!

Now, as long as Han Feng encounters a strong enemy that he can't deal with, he can completely launch the battle castle mode of the Unimog RV and use a long-term firepower strike to overwhelm the opponent.

After looking at the newly acquired Battle Fort mode this time, Han Feng turned his gaze to the hologram of the Unimog RV again.

After the mechanical core completed the breakthrough mission, new evolution options appeared in front of him.

However, when Han Feng saw clearly the evolution option of the mechanical core this time, a very strange look appeared on his face, and he had deep doubts about the origin of the mechanical core.

"The mechanical core has evolved, please choose the direction of evolution." With the electronic tone sounding again.

The evolution options on the left side of the hologram reminded Han Feng of the Calamity Angel-class battleship under the medicine capital, and he had a feeling that the evolution direction of the mechanical core was shifting, and now the mechanical core in his body was no longer satisfied with the small stage of the earth.

"Option 1: Add a vacuum support system, after the vehicle turns on the vacuum support system, it will automatically lock all the parts of the vehicle that can be opened, and at the same time, an oxygen generator will be added to the inside of the vehicle, which can absorb all kinds of gases in the universe, including hydrogen particles and helium particles, and convert such particles into oxygen. In addition, the vacuum support system can also decompose the carbon dioxide in the vehicle into oxygen and water molecules, which will be converted into pure water and stored in the water tank. ”

"Option 2: Cancel the miniature nuclear reactor and add a miniature controllable fusion reactor to provide controlled fusion energy to the vehicle."

"Option three: the vehicle cancels the Seeker unmanned reconnaissance aircraft system, and adds a long-range space radar system, which can observe moving objects with a diameter of more than five meters within 1 astronomical unit."

"Option 4: Cancel the vehicle-mounted extra-dimensional space system and increase the super-dimensional space container, which has 500 cubic meters of cargo space."

"Option five: The vehicle will remove the alloy armor and superalloy armor coating, and increase the silver-like super-metal shell, and the silver-like super-metal shell defense will be equivalent to about 7000 mm of homogeneous armor."

"Option 6: The vehicle will add flame afterburner thrusters, and four flame afterburner thrusters will be added to the rear of the vehicle, and the flame afterburner thruster can provide propulsion beyond the fourth cosmic speed, and the forward speed can reach 110KM/s. (Flame afterburner thruster, which requires a miniature controllable fusion reactor as an energy source)"

"Option 7: The vehicle cancels the Heavenly Penalty Particle Plasma Cannon System and adds the Heavenly Penalty Electron Cannon System, which will call 10% of the energy of the controllable nuclear fusion reactor every time it fires, and use the gamma light quanta generated when the positron and negative electron are annihilated to carry out a large-scale attack. (The Tianyang electronic cannon system requires a miniature controllable nuclear fusion reactor as an energy source)"

"Option 8: The vehicle energy shield system is upgraded, and the energy shield system is upgraded from a civilian standard system to a shipborne small energy shield system, with a shield energy intensity of 1200 GJ, and the shield adopts real-time recharge technology, and the overall shield recharge time is 1 hour. (Shipborne small energy shield system, which requires a miniature controllable nuclear fusion reactor as an energy source)"

When Han Feng read all these evolution options, he found that the corresponding evolution options were all biased towards one aspect, that is, to leave the earth with his own strength, and at the same time have the ability to fight in the universe.

The first evolutionary option, the addition of a vacuum support system, is obviously to prepare for space travel, and only with a life support system, the passengers in the RV can survive in space without air.

At the same time, the oxygen generator that comes with the life support system is also a real perverted existence.

Even the International Space Station could not have such a thing.

Generally speaking, there are only a few dozen hydrogen and helium particles in a square meter in the universe, and these particles are completely incapable of human survival.

But the oxygen generator can actually extract these particles from space and convert these particles that humans cannot absorb into oxygen atoms to generate oxygen.

The life-sustaining system can even break down the carbon dioxide exhaled by the passengers in the car into oxygen and water molecules.

It is with the life-sustaining system that Unimog RV can survive in the universe for a long time.

As for the second evolution option, it is the basis for the evolution of the gold Unimog touring car.

Long-term space voyages, as well as amazingly powerful new weapons, all require powerful energy, as the basis of all this, and the next few evolutionary options also state that a miniature controllable nuclear fusion reactor is needed as an energy supply system, so the second seemingly useless miniature controllable nuclear fusion reactor may be Han Feng's first evolutionary choice.

The third evolution option, although the Seeker unmanned reconnaissance aircraft system has been cancelled, but the new long-range space radar system is also a necessary thing to survive in the universe, if there is no space radar system, then once the Unimog RV leaves the earth, it will definitely become a blind man who can't see anything in the dark universe.

At the same time, after the cancellation of the vehicle-mounted super-dimensional space system, the new super-dimensional space container, compared with the previous generation of products, is completely two things.

The vehicle-mounted extra-dimensional space system can only store twenty cubic meters of materials, usually twenty cubic meters of materials, which is really enough for Han Feng to use at most, but a five-hundred-cubic-meter super-dimensional space container is completely different, five hundred cubic meters of materials can definitely be used as a supply for a survivor team, and it can also be used for a long time.

Finally, the fifth to eighth evolutionary content is entirely to allow Unimog RV to have the ability to fight in the universe.

The silver-like super-metallic shell has been replaced by the removal of alloy armor and superalloy armor coating, which has an ultra-strong defense layer that is unimaginable to ordinary people, which is equivalent to about 7000 mm of homogeneous armor.

The thickest armored battleship in human history, the frontal armor of the turret of the Yamato-class battleship is only 650 mm, and it is completely inconceivable that this silver-like supermetal-like shell has homogeneous armor equal to seven meters thick.

Normally, the thickness of the steel plate of the gate is only four meters for the permanent fortification against nuclear weapon attacks, and if it is calculated in this way, as long as the nuclear weapons do not hit the Unimog RV head-on, the powerful nuclear weapons will have nothing to do with the Unimog RV.

The Flame Afterburner Thruster, on the other hand, is completely new.

At present, the strongest artificial space vehicle on the earth can only provide an engine that barely breaks through the third cosmic speed, that is, the maximum propulsion speed can barely reach 16.7KM/s, and the life of this engine is quite short, and it can only barely let the aircraft get rid of the earth's gravity and fly into space.

If you want to rely on such power to leave the Milky Way, it is completely a fool's dream, and it took more than 30 years for the farthest man-made vehicle on Earth to slowly leave the solar system and move towards the vast interstellar space.

However, this artificial flying machine can only do that, because the speed provided by its engine can only reach 17KM/s, this kind of third cosmic speed that barely breaks through the gravitational constraints of the solar system, so that no matter how long it takes, this artificial aircraft will not be able to fly out of the galaxy.

BUT THE FLAME AFTERBURNER THRUSTER IS DIFFERENT, ITS ENGINE CAN PROVIDE A SPEED OF 110KM/S, AND THE SPEED OF 110KM/S IS THE MINIMUM INITIAL SPEED FOR A MAN-MADE OBJECT TO BREAK THROUGH THE GRAVITATIONAL PULL OF THE MILKY MILKY GALAXY, THAT IS TO SAY, AFTER HAVING THE FLAME AFTERBURNER THRUSTER, UNIMOG MOTORHOME HAS THE CAPITAL TO LEAVE THE GALAXY.

As for the Tianyang electronic cannon, in Han Feng's view, it is just an upgrade of the weapon system, which further improves the lethality of the main weapon, after all, if you need to fight in space, then the heavenly punishment particle plasma cannon, with a pitiful five-meter range, is like a person holding a toothpick to fight, and it has no lethality at all.

At the same time, the final replacement of the civilian standard energy shield system with a shipborne small energy shield system only makes the energy shield system thicker and thicker, unlike the current energy shield system, which will shatter piece by piece after a few attacks, and then dissipate in the air.

After Han Feng had read all the evolution options of the mechanical core, he withdrew from his mind, showing the hologram of the Unimog RV.

When his gaze refocused on this slightly empty underground space, some of the evolutionary options he had just seen felt a little unreal to him.

The evolution options of the mechanical core just now made him feel as if he was already in a sea of stars, heading towards the vast universe.

But when he returns to reality, he finds that he is still just driving an RV, struggling to become stronger in this chaotic apocalypse.

However, Han Feng just shook his head and threw these thoughts out of his mind, and then he hugged Wu Yuli, who was still in a coma, and re-boarded the gold-level Unimog RV.
