After the powerful Tianyang electronic cannon hit the gold-level mutant hen, the cells on the surface of the mutant hen were killed by gamma rays.

After only a moment, the surface of the mutant hen's body festered, and Han Feng jumped out of the Unimog RV, and harvested a gold-level life core very smoothly.

Han Feng took the life core in his hand, and muttered in his heart, the extract obtained from the corpse of the Lan Sky Guard member could actually make an ordinary creature quickly turn into a gold-level mutant beast.

If this extract was used in large quantities, wouldn't it be possible to create gold-level mutant beasts in batches, as long as the Apocalypse Organization could kill these gold-level mutant beasts, the endless gold-level life cores would be beckoning to them.

And according to this reasoning, as long as he can be ruthless and give this extract to the human survivors, then the human survivors will also be transformed into gold-level zombies.

In this way, in a very short period of time, the Apocalypse Organization will be able to have a large number of gold-level evolutionaries, and the rapid expansion will be much faster than the use of the Adjudication Weapon System in the Eastern Security Zone to carry out the ability improvement plan.

But whether to do this or not, Han Feng was still struggling in his heart, and it would be too hypocritical to say that he was not moved by this at all.

Now in this last world, we still respect strength, and only with enough strength can we grasp enough power to speak and make our own voice heard.

"Let's go back and talk about that." Han Feng first left the extract obtained from the corpse of the Lan Sky Guard for the human survivors to use.

At this moment, he focused his gaze on the red desert in front of him.

The last time he came to the alien ruins, he had discovered the secrets inside the alien ruins, and there was antimatter under the alien ruins.

Han Feng looked at the gold-level life core in his hand, which seemed to still exude the body temperature of a mutated hen, and without any hesitation, he directly put the life core in his hand into the center console of the RV, the cylindrical metal slot that had already popped out.

When this gold-level life core that shone faintly was absorbed by the cylindrical metal trough with a mechanical click, another electronic prompt sound appeared in Han Feng's mind.

"The mechanical core has successfully absorbed the high-energy life source, and the mechanical core has evolved since its beginning, please choose the direction of evolution."

In Han Feng's mind, the evolution options of the only two remaining mechanical cores began to shine again.

"Additional evolution option one can be opened: the vehicle can add an energy recovery device, which can absorb various high-energy substances contained in the space through the adsorption recovery tube and store these substances."

"Additional Evolution Option 2 can be opened: 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."

The Gold-level Life Core just now unlocks one of two additional evolution options.

Faced with these two evolution options, Han Feng didn't even think about it, and directly chose to let Unimog RV and add energy recovery devices.

After knowing that there is antimatter in the underground of the alien site, the most important thing is to find a way to get rid of the antimatter smoothly.

When Han Feng clicked on the extra option one, the electronic prompt sound in his mind sounded again: "Selected: The vehicle has an energy recovery device, and the high-energy life source meets the standard, please put 100 kilograms of first-class gold essence, 100 kilograms of first-class antimony essence, and 100 kilograms of first-class tungsten essence in the pop-up physical material conversion cabinet." ”

"Fortunately, the demand for physical materials for energy recovery devices is not very high."

Han Feng also breathed a sigh of relief after listening to the electronic sound ringing in his head, prompting the addition of energy recovery devices and the physical materials needed.

It is not too exaggerated to increase the materials required for the energy recovery device this time, and at the moment, the inventory of these material essences in the Unimog RV is relatively sufficient.

As the mechanical core automatically extracted these materials from the RV and added them to the physical material conversion cabinet, the appearance of the Unimog RV showed a slight change.

After activating the newly added energy recovery device, the logo in the middle of the front of the original Unimog RV began to quickly fold and fold inward.

Then a metal-like probe with a silver sheen of two meters long stretched out from the middle of the front of the car, where the logo was originally hung.

Of course, this metal-like probe that pokes out from the position of the car logo is not a completely solid metal, but an unknown substance that looks very much like solid metal.

Moreover, this metal-like probe is completely hollowed out in the middle, and at the top of the metal-like probe, there are many small holes that are invisible to the naked eye, and the size of these small holes has reached the nanometer level.

Han Feng didn't have any surprised expression on his face when he saw the front of the Unimog car growing a metal-like probe two meters long.

Now the appearance of the Unimog RV can no longer be described as weird.

The length of the entire body is more than 20 meters, half of which is contributed to the flaming afterburner at the rear, while the other half belongs to the RV itself.

When this metal-like probe sticks out of the RV logo, the whole RV looks like a freak, without any aesthetics.

However, as Han Feng, of course, he will not pay attention to the shape of the RV, whether it is too weird.

He focused on only one thing, and that was combat effectiveness.

As long as the Unimog RV has enough combat power, even if it looks like a freak, Han Feng will still choose to use the RV to fight without hesitation.

At this moment, in the middle of the front of the RV, after the metal-like probe at the car logo stretched out, Han Feng re-aimed his gaze at the red desert in front of him.

He drove the Unimog RV along the alien site, with the central axis of the earth mountain in the center of the site, and advanced 323 meters to the location of Lake Toto on the left.

"This should be it."

When Han Feng first left the underground part of the alien ruins, he backfilled the open road, so the backfilled area was much softer than the area without backfilling.

When the huge Unimog RV had just driven into the backfilled area, Han Feng immediately felt the change in the soil below.

Then he drove the RV, retreated more than ten meters, directly adjusted the muzzle of the 75mm microwave laser automatic rapid-fire gun, and then without a little hesitation, directly activated the automatic rapid-fire gun.
