Now that he has 600,000 magic crystals, Wang Haoyu can consider upgrading the system. Pen, fun, and www.biquge.info

I opened [My System] and saw a three-dimensional image of the courtyard. At this time, Wang Haoyu saw that Lin Wanting was sleeping in the house, and in the battle preparation room, Li Tao and seven dragon guards were on duty there.

Swapping the magic crystal for city energy points, Wang Haoyu clicked on the option of upgrading the house.

With the reduction of 100,000 energy points, Wang Haoyu saw the entire courtyard shake. And the next moment, everyone in the combat room fainted.

A burst of silver light flashed, and the original courtyard suddenly turned into a small base.

This base is four times the size of the original, and according to the numerical figures, this small base with a length and width of more than 200 meters has a total area of 50,000 square meters. And at this moment, Wang Haoyu's wild building can really be called a base.

The original architectural layout of the site has also been changed, with a large five-story castle-like building in the center, and two additional three-story villas on either side of it.

Around the villa is a small two-story building like before, and there are sixteen of them.

Immediately afterwards, Wang Haoyu chose to upgrade the defense system, and also spent his 100,000 energy points.

Another flash of silver light flashed, and the next moment the original layout of the base changed somewhat.

When there was no defense upgrade before, Wang Haoyu thought it was a whole, but now it seems that this pattern is a bit like a courtyard house in the real world.

The perimeter of the base was ten meters high, and the outer sides were covered with barbs that shimmered with cold light. The interior also has a fence that encloses the small castle and two villas. In this way, the base formed a double wall defense.

At this time, the distribution of weapons was also reorganized, and all the walls were full of machine guns, and above the small building were small cannons. On the two three-story villas, each has two cannon barrels. As for the "array phalanx artillery system", it was installed on the small castle in the middle.

After upgrading, both in terms of appearance and overall strength, it is far superior to before. From the outside, Wang Haoyu's base is a behemoth, which is extremely shocking.

And the next moment, Wang Haoyu spent 300,000 energy points to upgrade the [Minecraft] main system to level 4.

This is what Wang Haoyu is most concerned about, and after a flash of golden light, the system was finally upgraded.

Wang Haoyu saw that the most important point was that the movement speed of the base upgraded to level 4 had increased from 1 meter per second to 3 meters per second.

The speed has tripled!! This is something that Wang Haoyu did not expect before.

Having reached such a speed, an hour will be able to move ten kilometers. Although it may not seem fast, it can move more than 200 kilometers in a day. With such a mobile castle, Wang Haoyu is equivalent to getting a sharp weapon.

In addition, Wang Haoyu was more concerned about the exchange system, and thinking of this, he hurriedly opened the exchange column.

In the weapons slot, there are now laser guns and nanoguns in addition to the pulse guns. The Nano Gun is a new type of weapon, and the price tag is not cheap, requiring 5000 energy points, but according to the description, it can directly kill level 2 boosters.

In addition to this, for the first time in the weapon system, tanks appeared. The price of this magnetron tank, named W-1, has reached the outrageous point of 10,000 energy points.

But when he saw that he had an effective range of five kilometers, a moving speed of 150 kilometers per hour, a three-level defense system, and so on, Wang Haoyu's heart was a little affected.

In addition to this, there is an additional armored personnel carrier, which is three times the size of the previous one. The speed, like that of the W-1 magnetron tank, reached 150 km/h. At the same time, he was able to carry fifty people. And most importantly, its weapons system. In addition to two machine guns, a small cannon was placed on it.

In addition to being able to transport troops, this armored vehicle has not weak firepower. Such an armored vehicle kills two birds with one stone, and it requires 5,000 energy points.

In addition to this, for the first time in the exchange system, it is possible to redeem small unmanned aerial vehicles. It is possible to fly within a base range of 20 km, with a surveillance system that allows the screen to be transmitted back to the base, and a storage compartment capable of carrying 10kg of items.

It's a good thing!!

Seeing the attributes of the small flying machine, Wang Haoyu secretly said in his heart.

Although it can not carry much, it can transport supplies within a radius of 20 kilometers. Sometimes, at the most critical time, such small flying vehicles can play a vital role.

And its price is the same as the W-1 magnetron tank, which requires 10,000 energy points, which is really not low.

As for the daily necessities in the exchange column, there is an additional level 2 enhancement potion, with a price of 10,000 energy points. It works 100% to raise an ordinary person or a Level 1 Booster to the level of a Level 2 Genetic Booster.

For Wang Haoyu, this price is cheap and not cheap.

The cheap one is that it only takes 10,000 energy points to be able to raise a person to level 2 enhancer, which is sometimes unattainable for those who have money, even if they want to spend more.

What is not cheap is that Wang Haoyu will inevitably have many subordinates in the future. One of 10,000 magic crystals is simply too expensive.

But he didn't have time to think about the future now, because the next thing he saw drew his gaze to it.

【Medium Tactical Missile】

[Range: 20,000 meters]

[Radius of Destruction: 100 meters]

[Lethality: Level 3 Booster within 5 meters of the core, Level 2 Booster within 20 meters of the core.] 】

[Exchange price: 50,000 energy points]

Wang Haoyu's eyes lit up when he saw this medium-sized missile, a medium-sized missile that can kill a level 3 enhancer, and with such a large killing radius, it is definitely a good thing.

It's just that the price of this medium-sized missile is too expensive, and it is shameless to 50,000 energy points each. And now Wang Haoyu only has more than 100,000 magic crystals left after upgrading these systems. If you want to redeem it, you can only redeem two pieces.

The price of exchange items in the system is getting higher and higher, and now it is like this, what will happen in the future? Wang Haoyu didn't dare to imagine.

Suddenly, Wang Haoyu, who was in the hotel room, heard the sound of an argument upstairs. Due to the fact that the room is very well insulated, this sound sounds very small. But Wang Haoyu is a level 4 enhancer, and his perception ability is far beyond ordinary people. At this time, he held his breath and listened carefully to the conversation upstairs.

After listening for a while, Wang Haoyu's eyes flashed with a gleam, hesitated, opened the door and walked upstairs. (To be continued.) )
