Originally, the system could only be exchanged for two aircraft, but now it has become an aviation system. Pen & Fun & Pavilion www.biquge.info just hearing this name, it is much taller.

The unmanned aerial vehicles and manned aerial vehicles in the system are still there, nothing has changed.

And underneath them, there is a flying machine that can be exchanged.

【Medium-sized manned aircraft】

[Number of passengers: 10]

[Flight speed: 500 km/h]

[Weapons: 4 small homing missiles, 2 pulse machine guns]

[Maximum flight altitude: 8000 meters]

[Fighting ability: B level]

Seeing these attributes, Wang Haoyu smiled. This manned vehicle is definitely a lot better than before.

Speed alone solved Wang Haoyu's previous worst concern.

The flying speed of those birds of prey in the last days is not low, especially the few birds of prey encountered here in the southern region, the speed is almost close to 300 kilometers per hour. At such a speed, it is dangerous to take a general aircraft.

But now this medium-sized aircraft solves this problem, and the flight speed of 500 kilometers per hour is simply not something that the Raptor can catch up.

The biggest threat in the air was lifted, and Wang Haoyu was finally able to fly safely in the air.

Not only the speed, but also the number of people carried by this medium-sized aircraft has reached 10, so that Wang Haoyu can carry more people to fly.

On top of that, this flying machine can carry weapons. When encountering dangerous situations or using some tactics, you can use the weapons on the aircraft to achieve some goals. Although the firepower is not very strong, it can sometimes have unexpected effects.

However, such a medium-sized aircraft actually costs 2 million energy points each. Fortunately, Wang Haoyu is now able to absorb 1 million energy points from the crystal every day, and at this rate, he can exchange one in two days.

In addition to medium-sized aircraft, there is also an exchangeable item in the space system called the Sky Eye.

The range of images that can be detected by the Sky Eye is 500 meters, but the transmission distance reaches 300 kilometers.

In other words, if you install the Sky Eye decoration anywhere within 300 kilometers, you can see the situation within 500 meters. This device is a bit like a monitor, but the transmission distance is very long.

In the last days, because there may be interference waves in the air, many devices that could have traveled long distances have been reduced exponentially. Just like unmanned aerial vehicles, the distance that could have been transmitted before the end of the world could have been hundreds of kilometers or more. After entering the end of the world, its image travel distance is only 20 kilometers.

And the same goes for walkie-talkies, so don't mention those mobile phone calls. But walkie-talkies were also available before the end of the world, and they were generally used in the troops, and their transmission distance was at least 100 kilometers. Today, it has been shortened to 5 km.

In the last days, without the transmission of signals, human beings are like having no eyes. Even with the help of unmanned aerial vehicle reconnaissance, people can only observe a limited range. Sometimes when the beast tide is discovered, it is too late for humans to want to be in the car.

And now this eye in Wang Haoyu's system can actually probe a range of 300 kilometers, and the advantages are naturally self-evident. Whether it's scouting the beast tide or fighting against other forces, having the advantage of the Sky Eye will improve a lot.

One of the Tianyan devices is 100,000 energy points, which is a bit expensive, but it is worth the price.

Although the aerospace system only has these two items, the benefits to Wang Haoyu are huge. With these two items, it will be a lot more convenient.

And how do you think there are a lot of things in the exchange system, with the upgrade of the system, now Wang Haoyu can already exchange for level 4 enhancer elixir. It's just that the price is very high, and it takes 1 million energy points.

Wang Haoyu only needed 500,000 energy points when he was promoted to a level 4 enhancer, but if he exchanged it for a level 4 enhancer potion, it was doubled.

This price may seem expensive, but sometimes there are many people who need him.

Just like some Level 3 Enhancers, they may have more than 1 million in wealth, but they can't be promoted to Level 4 Enhancers.

You know, the difference between a level 3 booster and a level 4 is not as simple as one plus one. A level 4 booster can sweep several level 3 boosters. Just like that time in the Ao Long base, although Yang Tianlong was a level 3 enhancer and had a helper, he was still so powerless in front of the level 4 enhancer.

If there were 1 million magic crystals, I believe those people would not be stingy with this money. Not even 1 million, even 2 million or more, there may be people who need it.

Previously, Wang Haoyu only took out a level 1 enhancer elixir and sold it at the Tianjiao Auction House for 10,000 magic crystals. And according to the other party, it is likely to be taken out for auction.

If that's the case, then if he takes the level 4 enhancer potion to the auction, he doesn't know how many magic crystals he can get. Moreover, there are so many bases in Tianhua Kingdom, if you turn these bases around, how much money you can make, Wang Haoyu can't imagine.

But despite this, Wang Haoyu was not ready to sell the level 4 enhancer potion, because for his base, the level 4 enhancer was still a threat without him.

Although with the blessing of the king's energy, it may be that level 4 mutant beasts and zombies pose no threat to the base. But the Enhancer is different, and if such an enemy comes to the base, there is still a certain threat.

Before the base is strong enough to deal with all threats, Wang Haoyu will definitely keep the good things and will not pass them on.

In addition to the level 4 enhancer elixir, there is another thing worth Wang Haoyu's attention, that is, the inducer.

After reading the instructions on the inducer, Wang Haoyu's eyes lit up.

But judging from the description, the inducer is the opposite of Wang Haoyu's kingly spirit. The king's breath is to expel mutant beasts and zombies, and it can be immune to those low-level mutant beasts and zombies. The effect of the inducer is to attract zombies, which can attract zombies.

This seemingly chicken rib thing may sometimes have an unexpected effect. For example, sometimes a material is found, but there are a lot of mutant beasts and zombies around. At this time, using inducers to attract those mutant beasts and zombies to other places can reflect the value of inducers. And its price is not expensive, as long as 10,000 energy points a bottle, the range is 100 meters.

Seeing these things in the system, Wang Haoyu made a decision, that is, to go back to the central part. Seeing that there are still three days to reach the predicted deadline, Wang Haoyu wants to ensure the safety of the base.
