Zhang Tuohai checked the data of the hand-thrown drone.

It has a take-off weight of two kilograms, a duty radius of 10 kilometers, a flight duration of 1.5 hours, and a speed of 30 kilometers per hour. It is equipped with an infrared camera and the ground terminal can be directly connected to the vehicle control platform.

A very obvious "low, small and slow" aircraft. If you have this thing, Zhang Tuohai's combat method will be fundamentally changed.

His main observation mode can also be changed from physical observation (eyes plus telescope) to drone reconnaissance.

Moreover, with drone-assisted positioning, his Hellfire and Cornet can also exert their true power - used to attack targets beyond visual range, rather than close-defense rockets.

The only regret is that the take-off weight of this drone is too small, so it can only be used for reconnaissance, not attack.

In addition to the advantages of these weapons, the new vehicle's body is more airtight, waterproof and leakproof. It can travel on the river surface and briefly enter the river bottom. If necessary, it can conduct short-term activities on the shallow sea bottom.

These are all features that come with new cars.

In addition, the speed of the vehicle has also been improved, with the maximum speed increased to 300 miles.

After weighing the pros and cons, Zhang Tuohai finally chose such an upgrade route.

A white light shines on the infantry fighting vehicle, and the vehicle begins to upgrade.

The 125mm main gun and the thick rotating assault gun were removed, and the body shape was changed from a rough infantry fighting vehicle to a body made of multiple edges and corners, which looks more modern and has a more reflective radar surface.

Small, looks more like a multi-purpose armored vehicle.

Because the anti-radar surface must be taken into consideration, the weapon positions are also restricted. There are a total of six weapon positions on the roof.

Zhang Tuohai thought for a while and left two of them for Adaz multi-purpose missiles. This will be his main attack method in the future. Of course, there will be more.

Of the rest, one is reserved for the Kornet anti-tank missile and the other is reserved for the Hellfire anti-tank missile.

These two are used to attack difficulties.

Of the last two, one is reserved for the 1130 close-in defense gun, and the last one is reserved for the laser launcher.

One is used to deal with dense small targets, fast targets, or rockets and aircraft, and the other is used to deal with some targets that are difficult for missiles to deal with when the weather is good.

After the Kornet anti-tank missiles are used up, the 1130 close-in anti-tank cannon can be used to fill the vacancies, which seems to be the optimal arrangement at present.

Of course, these are usually stored in the car body, and the hatch cover is opened only when used.

As for the hand-thrown drone, Zhang Tuohai planned to throw it himself, so he didn't need to take up a valuable weapon slot.

Zhang Tuohai thought for a while and installed mechanical arms on both sides of the car body. These are auxiliary equipment and do not occupy the weapon slot.

However, Zhang Tuohai can still let them hold four 23mm machine guns or honeycomb rockets to assist in the attack.

It’s a bug in the game system.

Of course, the control terminals of these weapons were connected to the spherical screen by Zhang Tuohai, and were assisted by Xiao Ai.

[The vehicle upgrade is completed, and the conditions for upgrading to Level 6 have been issued, please check.]

Zhang Tuohai immediately took a look at the requirements for upgrading to level six.

Upgrade conditions: 0/8 level 5 general auto parts need to be installed, 0/4 level 5 special auto parts need to be installed, and a 0/1 level 6 vehicle upgrade drawing is required.

Zhang Tuohai looked at the upgrade conditions and couldn't help but curl his lips.

He found that the number of accessories needed to upgrade the vehicle had increased.

"It seems to be getting harder and harder."

Zhang Tuohai scratched his head and sighed.

However, now that the car has been upgraded, several drawings that have been prepared can also be used.

The first is titanium alloy armor, which is a level 5 universal accessory. After modification by Lilith, its defense power has reached the level of immunity to direct fire from rifled guns below 200 mm, or direct fire from armor-piercing projectiles below 125 mm.

The defense capability has been greatly improved.

It can be said that Zhang Tuohai can almost ignore the old artillery except train guns and naval guns.

The second is to load the advanced ecological park expansion package.

This is an upgrade plug-in, not counting accessories. After loading, the area level of the high-end ecological park has been further expanded. There is an additional saltwater lake at the edge, with a complete ecological chain. Zhang Tuohai will put in the bonus sea cucumbers, scallops and seaweed.

Once inside, he can also put some saltwater fish he catches in, so that he can have a steady stream of fresh seafood to eat.

The last one waiting to be built is the presidential suite.

What Zhang Tuohai values ​​most is not its huge area and luxurious decoration, but that it is a level 5 universal accessory and has a BUFF that doubles the speed of injury recovery.

A series of white lights flashed, and everything Zhang Tuohai needed to build was completed.

Zhang Tuohai looked at what was waiting to be built.

Materials required for chameleon camouflage: 20 barrels of paint of different colors.

"Weird upgrade conditions. I hope the next world can be a normal world where I can buy these things."

Zhang Tuohai looked at the production materials and couldn't help but sigh.

This material is not easy to work with.

In a disaster world, these things are almost first-class garbage. Except for the necessary waterproof coating, almost no one collects them, and there is no place to exchange them.

Zhang Tuohai can only hope that there is a way to buy it.

After finishing organizing things, Zhang Tuohai looked at his fully upgraded infantry fighting vehicle and nodded with satisfaction.

No, it can no longer be called an infantry fighting vehicle. It should be a multi-purpose armored vehicle that integrates air defense, ground defense, water surface defense, close defense, assault, reconnaissance, flying, and diving.

Zhang Tuohai drove his brand-new multi-purpose armored vehicle around the top of the mountain, and after confirming that no other facilities were left behind, he came back to the many light gates.

Zhang Tuohai took a deep breath: "I hope it is a favorable world!"

After saying that, Zhang Tuohai stepped on the accelerator and rushed into the light door, which represents experiencing the next world in advance.

The white light dissipated, and Zhang Tuohai quickly took stock of his surroundings.

The ground is a flat cement pavement, surrounded by wooden two-story buildings with red roofs and white walls. It looks like a foreign town.

Seeing this, Zhang Tuohai breathed a sigh of relief, feeling that he should have arrived in a modern world, and the paint problem should be solved.

However, when he took a closer look, he couldn't help but take a breath of air.

Because the surrounding environment is obviously a bit dilapidated. There are broken papers and garbage everywhere on the ground. Several houses have broken glass everywhere. Some houses even have obvious signs of fire. There are several cars parked on the road due to collisions.

And scrapped cars.

You can even see some blood stains and mottled bones that have turned black on the road.

"What kind of world is this here?"
Chapter completed!
