After returning to the base, Hu Hai was busy getting fitness equipment, this old man has a very strong hands-on ability, and the tensile treadmill can be made by himself.

Zhang Zhen looked at the 130,000 energy and couldn't help but be excited, this is a huo, you can upgrade everything you have always wanted to upgrade.

First upgrade the protective attributes of the chariot hull, the last time I collided with the cowhide pickup, it was reduced by 15 percent, the reduction is quite high, anyway, the vehicle residue left by the two marauders is still there, and the corpse was disposed of, and the car burned into a pile is quite an eyesore.

The Tomahawk stopped and opened the system to check, just these two scrap vehicles can increase the vehicle's hull defense to B-level, and at the same time have C+ attack power, which means that low-level alien beast chariots can also be directly crushed by the hull.

The appearance of the chariot can still be adjusted, Zhang Zhen pondered it and found that the design was perfect, and then changed it indiscriminately to destroy the aesthetics and decided not to move.

The only thing that affects the beauty should be said to be the appearance when disguised as a three-wheeler, but in order to avoid the trouble of not avoiding in reality, the traffic police uncle checked the license plate can only be like this.

Enhancement requires twenty-three thousand energy, Zhang Zhen really didn't frown, he thought that energy was too difficult to obtain, but now he found that it was so simple.

Under the shroud of light and mist, the body and engine of the scrapped car and other materials turned into fragments and energy poured into the tomahawk, which lasted for about three minutes, and suddenly the white light dissipated, and the dark body of the tomahawk shone even more, even under the gloomy sky, it was still as bright as obsidian.

The system prompts the body defense level B, attack power C+, and 60% evolution completion.

Next is to strengthen the tires, but the only thing that can provide materials nearby is the heavy-duty pickup truck bought for Hu Hai, just to upgrade a wheel to destroy the heavy truck is not worth it, next time I go into the town to buy a pair and come back.

The energy conversion device asked for special materials, and I opened it in front of the door and scanned it, the only thing that met the requirements was the old optical brain that Hu Hai bought back last time in his room, it seemed that Hu Hai was still repairing, and the chips were dismantled.

"Lao Hu, I used your light brain, I'll buy you a good one next time."

Zhang Zhen shouted at Hu Hai, who was busy tinkering with fitness equipment in another room, and walked out directly with a bunch of parts.

Hu Hai sighed helplessly, and it was about to be repaired.

The installation of energy conversion device is primary, which requires 10,000 points of energy, and the materials are owned, is it upgraded?

"Upgrade, of course."

Zhang Zhen couldn't wait to confirm it, and another cloud of white light was enveloped on the light brain, which was completed in about a minute, but there was nothing more on the tomahawk.

When I inspected the system, I found that this thing is the core device of the tank, so it will not be visible, but in the integrated control interface, energy conversion can be carried out, and in the weapon interface, the previously installed Gold Hunting Gun has the option to switch to using energy bullets.

Zhang Zhen upgraded the energy conversion and waited for this moment, and immediately launched the order to add it.

"The energy bomb is refilled, and a total of 100 energy points are consumed."

Looking at the prompt, Zhang Zhen found out after a little research, no wonder it is called primary energy conversion, it turns out that with the upgrading of conversion equipment, the attack power of the energy bullet will also increase, and now the energy bullet of the gold hunting gun belongs to the medium-shaped shaped shaped energy bomb, the damage is B-level, and the damage range is ten meters.

Zhang Zhen looked around for a while, and found a one-meter-square stubborn rock nearby, so he drove the tomahawk over.

The attack distance of the Gold Hunting Gun is 10 meters, and the closer you get, the higher the damage, so that the tomahawk stops at 8 meters, which is almost safe when facing dangerous monsters.

After having a central console, you can manually look at the hemispherical interface of the center console to lock on to the target manually, or you can use your mind to control it directly from the system.

Zhang Zhen stretched out his hand and clicked on the interface of the center console, and the gold hunting gun instantly adjusted the body of the gun to show the lock, and then clicked on the icon of the gold hunting gun, and with a bang, it felt very normal, and a ball of white ball-like light erupted from the mouth of the gold hunting gun.

It doesn't look very fast, it's a bit like a snowball the size of a small potato.

Zhang Zhen thought that he would have to squeeze an egg yolk out of the stone with a bang, but suddenly there was a loud bang, and the stubborn stone instantly exploded from the middle, and the central area simply turned into a pile of stone powder in an instant, and the power expanded outward, and the periphery of the stubborn stone was shattered into small stones like a collapse and flew out like a torrential rain.

"My good man, this has to be hit on people, and I can't break my bones with one shot!"

Zhang was stunned, what kind of gun is this, it's a sci-fi weapon, if it hits the corpses, it is estimated that it can kill dozens of them with one shot.

Seeing Hu Hai send a message with a green shield saying that dinner was ready, Zhang Zhen also felt hungry and went back to the base.

There are still 100,000 energy after the upgrade, only a fraction of the time, 10,000 energy points are needed to upgrade the front and rear wheels, and there are 90,000, these 90,000 have to be studied slowly, and the completion of the front and rear wheels is about eighty, in addition to the material is not the best to reduce the completion, there should be a place that can be strengthened to increase the completion, otherwise there is no way to upgrade the progression.

After dinner, I couldn't help but use the tensile machine made by Hu Hai to exercise for a while, although I haven't practiced much recently, but Fuxi needles will naturally give birth to the vitality of the body to strengthen, and it is already about to reach the C level, and it will be almost the same tomorrow if you spend a little time.

Shelley has been practicing yoga-like movements in the light brain for three hours today, and his vitality value has increased a lot, and it is estimated that he can reach E level from E- in a few days.

Zhang Zhen sat on the sofa and fed oranges to Shelley who was lying in her arms, this girl didn't even eat it herself, only he fed it, and she was willing to eat it, and she was a sticky kitten.

He is dedicated to two purposes, studying the chariot system to see how to strengthen it next, many things have no materials so they don't think about it, and the practicality is not high, only the wheels are left in defense, and the rest is the weapon system.

Remotely tried to choose the Dark Thorn that was still in the cargo compartment, and found that if some enhancements could be added, such as automatic defense and multi-element bullet conversion, the completion could be increased by 15%, and the tire upgrade basically met the advanced requirements.

And the attack power is strong and terrifying, and the dark stab itself can use a variety of bullets, so after adding the element conversion, the original B-level attack ability can reach A-level, which is the attack value of ordinary weapons that has basically reached the limit.

However, the materials needed for elemental equipment are not available in the villa, and it seems that you will have to find them next time you enter the town.

In order not to let Shelley arouse his anger, Zhang Aurora could only deliberately put a blanket between him and Shelley when sleeping, and then ignore Shelley's hairy hands and feet and forcibly put him to sleep, otherwise he would not be able to control himself if he lacked willpower.

In the middle of the night, the green light on the green shield suddenly flashed, Zhang Zhen was awakened, and Hu Hai was also running upstairs in a panic.

Hu Hai stood outside the door and said in a panic: "My lord, the dog's eye has detected danger approaching us, and judging from the alarm display, it is either a strange beast or a very powerful zombie." ”

Zhang Zhen hurriedly dressed and said: "Send the ball to the roof, it can detect what is on the body." ”
