Apocalyptic Mechanical Chariot

When the armored vehicles that came to pick up Meng Wan'er and the survivors who had lost their hearing and headed for the Fucheng safety zone roared again, they returned towards the Fucheng safety zone.

Ning Xueru, who returned to the Unimog RV, immediately came to the small kitchen in the living area, rolled up her sleeves, and started preparing lunch for Han Feng.

Han Feng, who was sitting in the driver's seat, was constantly stroking the gold-level life core he obtained last night, thinking about whether to use the gold-level life core to upgrade the evolutionary options of the mechanical core.

If he can successfully obtain crystal energy supplements when he goes to the Magic City this time, then the gold-level life core in his hand will most likely be saved.

However, Han Feng sat in the driver's seat and only thought for half a minute before placing the golden life core, which was shining with colorful luster, into the cylindrical metal slot that popped up on the center console of the Unimog RV.

Although he is very likely to harvest crystal energy supplements when he goes to the Magic City this time, this is currently just a hypothesis and has not been truly realized, so for now, it is better for him to honestly upgrade the evolutionary option of the mechanical core.

After the gold-level life core was placed into the cylindrical metal tank, Han Feng's familiar electronic sound sounded again.

"Selected: Vehicle energy shield system upgrade. The energy shield system has been upgraded from a civilian standard system to a ship-based small energy shield system. The energy intensity of the shield is 1,200 GJ. The shield uses real-time recharge technology and the overall protection The shield recharge time is 1 hour."

After struggling for a moment, Han Feng chose the latter among the two options of adding a silver-like supermetal shell and upgrading the energy shield system.

From last night's battle, he discovered that the energy shield system was indeed more useful than pure physical defense.

The energy shield system can defend against sonic, space attacks, etc., without any trace of attacks at all.

The addition of a silver-like supermetal shell is a bit dull. Although the thickness of the supermetal shell is approximately equal to 7000 mm of homogeneous armor, the supermetal shell can only protect against those that directly act on the surface of the Unimog RV. The attack cannot block the invisible attack.

"Selected: The vehicle energy shield system has been upgraded. The high-energy life source has reached the standard. Please put 500 kilograms of first-grade titanium essence, 200 kilograms of first-grade aluminum essence, and 100 kilograms of first-grade gold into the pop-up physical material conversion cabinet. Essence.”

Although Han Feng had already been prepared in his mind, when he heard the electronic prompt sounding the quantity of required materials, he still raised his eyebrows slightly.

The energy shield system has been upgraded from a civilian standard system to a small shipboard energy system, which requires dozens of times the amount of physical materials consumed to build a civilian standard system.

If the one hundred kilograms of first-grade gold essence were converted into ordinary gold, it would probably be piled up in front of Han Feng into a mountain of gold made entirely of gold.

Not to mention the 500 kilograms of first-grade titanium essence and the 200 kilograms of first-grade aluminum essence. Even if these two things were not replaced with ordinary materials, they could completely bury Han Feng alive.

However, after looking at the massive amount of materials in front of him, Han Feng was a little shocked, but in the end he still had a relaxed smile on his face.

The reason is very simple, that is, when he was in the Fucheng safe zone, he had already accumulated a large amount of material essence.

Although upgrading the energy shield of the mechanical core now requires a large amount of material essence, the material essence carried in the Unimog RV at this moment is enough to pay for this upgrade.

Therefore, Han Feng did not hesitate at all and directly chose to call the corresponding materials in the Unimog RV, fill them into the physical material conversion cabinet, and upgrade the energy shield system of the mechanical core.

When the essence of materials required to upgrade the energy shield system was continuously injected from the inside of the Unimog RV, the electronic sound in Han Feng's mind rang again.

"The energy shield system has been upgraded. The high-energy life source has reached the standard. The materials in the physical material conversion cabinet have reached the standard. The energy shield system is being upgraded... The energy shield system has been upgraded."

As the electronic sound sounded, the two rows of metal bars that were about two meters long and only ten centimeters wide and high at the middle of the body of the original Unimog RV suddenly began to expand.

These two metal bars turned into a circular metal circle surrounding the entire Unimog RV.

But to be honest, when the metal strips wrap around the body of the Unimog like a lifebuoy, the shape of the entire Unimog becomes a bit weird.

The current Unimog RV is like those bumper cars in the amusement park. The bumper cars are surrounded by a circle of black rubber, while the Unimog RV is surrounded by a circle of shiny pure metal strips.

At the same time, after these two metal bars become a metal ring surrounding the entire Unimog RV, the output power of the energy shield system will also increase several times year-on-year.

Of course, the increase in output power will definitely affect the energy shield and the damage it can withstand.

For example, the previous energy shield system could withstand frontal attacks from ordinary large-caliber artillery shells, but the current energy shield system can directly withstand frontal attacks from cruise missiles. This is the benefit of increased output power.

However, although the energy shield system of the mechanical core was upgraded, neither Han Feng nor Ning Xueru, who were sitting in the car, felt the changes in the RV.

It wasn't until Han Feng got out of the car and took a look around that he felt the change in the appearance of the RV.

And when he boarded the RV again, the smell of food wafted out from the living area of ​​the RV.

Ning Xueru was bringing a pot of vegetables to the small dining table and called to Han Feng:

"I've finished cooking your lunch. You come to eat now."

Han Feng looked at the glistening pot of braised chicken legs and a pile of green vegetables on the dining table. Naturally, he would not refuse. He sat down and directly picked up the rice bowl and enjoyed Ning Xueru's cooking. The delicious food.

However, Han Feng only took two quick bites of rice. Ning Xueru, who was sitting opposite him, could tell that something was wrong with Han Feng at this moment.

Although Han Feng was eating heavily, his extremely pale face could not be concealed at this moment, and a feeling of weakness appeared from Han Feng's body.

"You look so bad, what happened yesterday?" Ning Xueru had just taken a bite of rice and noticed the unusually pale look on Han Feng's face, and asked with concern.

Facing Ning Xueru's concerned inquiry, Han Feng shook his head slightly: "It's nothing, I just encountered a gold-level mutant beast last night, and I was slightly injured when I fought with that gold-level mutant beast. "
