When the huge body of the Unimog RV slowly ran over the shards of reinforced concrete blocking the entrance to the passageway and entered the completely dark underground passage, everything around was eerily silent.

In front of the Unimog RV, the downward passage illuminated by the xenon headlights was unusually quiet, only the roar of the engine when the RV was moving forward, and the surrounding of the passage was quiet, and there was no sign of life at all.

However, the downward passage is not too long, and the RV slowly descends the ramp at a 30-degree slope for two minutes before reaching the underground part of the alien ruins.

"It's ......"

With the Unimog RV, coming to the end of the passage, Han Feng was shocked by the scene in front of him.

At the end of the passage, a clearing the size of a standard football field appeared abruptly, and the rock layer at the top of this clearing, like those caves that had existed for hundreds of millions of years, had already shown signs of calcification.

In this dark ground the size of a standard football field, there are more than a dozen dark red fragments of different sizes erected on the ground, the larger fragments are about the same length as an adult's arm, and the smaller fragments are only the same as an adult's slap.

At the same time, these dark red fragments will also emit a faint red light towards the outside, which makes the atmosphere of the entire underground space very strange.

"If it's used as a stage for horror films, it doesn't need to be set up extraordinarily." Wu Yuli in the RV was also frightened by the strange atmosphere at the scene, and couldn't help but exclaim.

Just as Wu Yuli exclaimed, Han Feng, who was sitting next to him, suddenly changed his expression, and in his mind, the electronic prompt sound of the mechanical core appeared again.

"If fugitive antimatter energy is found, it is recommended to use an energy recovery device to recover the fugitive antimatter energy."

"Warning, the lack of energy recovery devices makes it impossible to recover the fugitive antimatter energy, and depending on the host's physical strength, the antimatter energy will reach the critical point of threat after 30 minutes, causing substantial damage to the host."

When Han Feng heard the warning from the mechanical core, he looked at the underground space in front of him that was emitting red light, and his sense of vigilance increased greatly.

He didn't expect that in this space under the alien ruins, there was actually a legendary antimatter energy source.

Before the outbreak of the apocalyptic virus, there was still a great deal of controversy in the scientific community about antimatter.

It is generally accepted in the scientific community that when antimatter meets positive matter, a huge amount of energy will explode, and after a few thousand grams of antimatter meets positive matter, the two sides will annihilate and cancel each other out.

According to calculations, the energy produced after the annihilation and offset of a few thousand grams of positive and antimatter is comparable to the energy produced after the explosion of a nuclear weapon.

Therefore, the scientific community is worried that once there is any mistake in the study of antimatter, then the huge energy generated after the annihilation of antimatter and positive matter will cause the earth to experience another 'big bang', and all life on the earth will cease to exist.

Of course, there is another way of saying that the huge energy generated when antimatter and positive matter are annihilated is the most likely and decisive energy source for human beings to grasp.

Once humanity can successfully master and use antimatter.

Then, relying on the huge energy generated when antimatter and positive matter are annihilated, it is possible for human beings to build a flying machine that travels at nearly the speed of light.

As long as human beings can have such flying machines, then interstellar colonization will no longer be a dream, and human footsteps will spread all over the universe.

"Boss, isn't there something lacking in the air in this underground space, why do I suddenly feel a little dizzy?"

Not long after the warning of the mechanical core sounded, Wu Yuli, who was sitting in the passenger seat of the RV at the moment, suddenly covered her head, but she didn't think much about it, she just thought that it was the lack of oxygen in the underground space that caused her dizziness.

"The degree of antimatter escape in this area is terrifying...... Han Feng found that Wu Yuli, who was a bronze-level evolutionary, had only been underground for about ten minutes before he showed signs of dizziness, and his heart was also shocked.

Then he didn't hesitate, immediately turned the steering wheel in his hand, turned the front of the Unimog RV, and let the whole RV quickly leave this underground space along the road from which it came, and returned to the surface.

And the RV had just come to the ground, and Wu Yuli, who was still holding her head and felt a little groggy, took a few deep breaths and immediately recovered.

"We rested in place for ten minutes, and then headed straight in the direction of the Fucheng Security Zone." After Han Feng saw that Wu Yuli beside him had returned to normal, he handed a map to Wu Yuli and asked her to memorize the route ahead.

And Han Feng himself opened his mind again, the hologram of the Unimog RV, just after the mechanical core and no energy recovery device was detected, two new evolution options were added to the originally dense evolution options.

"Additional Evolution Option 1: The vehicle is equipped with an energy recovery device, which can absorb various high-energy substances contained in the space and store them through adsorption recovery tubes."

"Additional Evolution Option 2: Vehicle Equipment Manufacturing System Upgrade, in addition to conventional equipment, the Vehicle Equipment Manufacturing System can use the materials stored in the energy recovery device to create special weapons."

Han Feng's eyes saw the names of some weapons that could be manufactured after the vehicle equipment manufacturing system was upgraded and combined with energy recovery and storage, and his heart jumped.

"Antimatter Annihilation Bomb, Quark Particle Fusion Bomb, Ghost Particle Penetration Bomb, Dark Matter Devouring Bomb."

Although the names of the weapons in this entire row were gray, the names of these weapons alone were enough to make Han Feng feel extremely frightened.

Any one of these weapons can instantly 'zero' all life on Earth, and it is completely unthinkable that the Unimog RV can make weapons of this level after having enough materials.

However, after the shock, Han Feng immediately calmed down.

Even if he cooperated with the energy recovery device and upgraded the vehicle equipment manufacturing system, most of the weapons he saw just now were also flowers in the mirror and moons in the water.

The reason is simple: to create these powerful weapons, you need to use energy recovery devices and collect enough raw materials to make them.

For the current Han Feng, he only knows that there are some antimatter raw materials under the alien ruins in Xia Du Province, and he is confused about the raw materials for the manufacture of other weapons, so at present, he will definitely not be in a hurry to upgrade the equipment manufacturing system to create those weapons that seem to be amazingly powerful.
