When Han Feng made sure again and found nothing similar to the appearance of crystal energy supplements, he quickly returned to the Unimog RV and put the crystal column in his hand, which was identified as a crystal energy supplement, into the cylindrical metal slot that popped up in the main center console.

When he returned to the RV, he also transported back a hundred kilograms of gold to extract the first-grade gold essence.

When Han Feng put the crystal energy supplement into the cylindrical metal tank, he found that the size of the crystal energy supplement was exactly the same as the size of the cylindrical metal tank.

It's as if this cylindrical metal trough was specially made for crystalline supplements.

"Could it be that this so-called crystal energy supplement thing really has something to do with the mechanical core?"

After discovering this situation, Han Feng couldn't help but muttered in his heart.

However, when he was still thinking about this question, the electronic prompt sound sounded in his head, which shook his heart fiercely.

"The mechanical core has been successfully resupplied, and the auto-evolved system has been completely lifted."

The moment the electronic prompt sounded, the evolution options in Han Feng's mind, which were originally in a gray state, had all been unlocked.

Originally, many silver-level life cores were needed to unlock the evolution options, but all of them have been unlocked, and now as long as enough resources are invested, all the evolution options of the Unimog RV can be effective.

After discovering this, Han Feng gasped.

What is the origin of this crystal energy supplement, and the energy contained in it is actually equivalent to the full energy of so many silver-level life cores, and it can light up all the other silver-level evolution options of the Unimog RV.

After reconfirming the evolution status of the Unimog RV, Han Feng directly began to upgrade the RV's weapon system.

When he chose to upgrade the Sky Dome Super High Energy Electromagnetic Cannon to the Heavenly Punishment Particle Plasma Cannon.

The semi-circular metal shroud on top of the Unimog RV began to change.

At the same time, it seems that materials are constantly emerging from the RV and filling into the semi-circular metal shield, which was originally semi-circular in shape, has been transformed into a large turret base with a height of about a meter.

After the completion of the turret base, it also began to extend to the front, and a barrel with an outer caliber of about 200 mm thick appeared at the front of the turret.

However, this barrel, which is about 5,000 mm long and glows with silver throughout, has a somewhat different shape from a normal barrel.

The barrel of the Heavenly Punishment Particle Plasma Cannon is not cylindrical like the normal barrel, because the physical cannonball needs to rotate and fly on its own axis to improve the accuracy of the cannonball, so the barrel can only be made cylindrical.

However, the Heavenly Punishment Particle Plasma Cannon does not need to be loaded with physical shells, so its barrel is hexagonal, which looks very full of technology.

Directly below the turret base, several large energy pipes with a diameter of 100 mm appeared, which were directly connected to the miniature nuclear reactor behind the RV's living quarters through the body of the Unimog RV.

The Heavenly Penalty Particle Plasma Cannon, every time it fires, it needs to call 40 energy sources in the miniature nuclear reactor, such a powerful instantaneous energy makes the pipeline that provides energy particularly thick.

Of course, this change in the internal pipeline, Han Feng sitting in the cab naturally has no way of knowing.

When he noticed the change in the Heavenly Punishment Particle Plasma Cannon, he stepped out of the RV.

At this moment, the appearance of the Unimog RV has changed very much from before.

If the original RV gave others the feeling of being a large box truck that was harmless to humans and animals, then the current RV finally has the appearance of a self-propelled gun.

The 5,000-millimeter-long, 200-millimeter-diameter, silver-glowing barrel on the roof of the car showed an unparalleled deterrent.

When the turret and turret of the Unimog RV, as well as the internal pipelines, were all completed, the electronic sound in Han Feng's mind rang again.

"The Heavenly Penalty Particle Plasma Cannon has been upgraded, and each fire will call the energy of 40 miniature nuclear reactors, and a stream of high-energy particles will be shot out of the barrel, causing indiscriminate damage to targets in the attack path, and the current fixed attack distance of the high-energy particle stream attack is five thousand meters."

With the completion of the upgrade of the Heavenly Punishment Particle Plasma Cannon, through the explanation, Han Feng also has a preliminary understanding of this plasma cannon.

The original Sky Dome Super High Energy Electromagnetic Cannon had an attack range of 120 degrees in front of the front of the car, and the attack method was a fan attack, and the attack range was 1,000 meters.

The current Heavenly Punishment Particle Plasma Cannon can only carry out linear attacks along the front of the car, and the attack range is extended to five thousand meters, which can cause devastating damage to all objects in a straight line distance of five thousand meters directly in front of the front of the Unimog RV.

However, there are naturally advantages and disadvantages, the Heavenly Punishment Particle Plasma Cannon is a linear attack weapon, and the attack distance cannot be adjusted, so it is necessary to pay special attention to the position and angle of the launch when Han Feng launches.

If there are zombies attacking Fucheng, he will fire the Heavenly Punishment Particle Cannon in the direction of the Fucheng safety zone with the front of the car, then this cannon will destroy the zombies at the same time, and by the way, half of the Fucheng safety zone will be blown away.

After the penalty particle plasma cannon is upgraded on the same day.

The Xunzhou Bank employees, who were responsible for collecting the items stored in the safe deposit box and carrying the gold, left the underground vault, and when they moved the rest of the things to the lobby on the first floor, the first thing that caught their eyes was the domineering Unimog RV.

Of course, Lu Jiaren, who had been to the first floor of the bank and had seen the Unimog RV, found that the RV in front of him had completely changed its appearance, and after a turret and a gun barrel with a length of 5,000 mm appeared on the top of the car, his face showed an incredible look.

However, he has both the city government and experience, so he naturally won't say it explicitly, but secretly meditate.

And Cao Kai, who was in charge of the command in the underground vault just now, saw the Unimog RV rushing into the hall of Xunzhou Bank for the first time, and when he saw the RV, he immediately walked quickly to the RV and carefully looked at the RV in front of him.

I have to say that the current Unimog RV satisfies most men's fantasies about vehicles.

The domineering hull, coupled with the deterrent cannon barrel at the top of the vehicle, made Cao Kai stand aside unconsciously, nodding his head with satisfaction.

Then he walked quickly to Han Feng's side and said, "We have got all the gold out of the underground vault, and now that there are so many of us, can we take your car and leave Xunzhou?" ”

Han Feng looked at the men and women standing in the hall of Xunzhou Bank at this time, and frowned slightly, he would not let so many survivors squeeze into the Unimog RV.

He directly pointed to a few survivors and ordered, "You guys come with me first, I'll help you get a few cars first, and then return to Fucheng together." ”
