This giant cannon can be said to be a collection of the most cutting-edge biotechnology, so that it can reach the level of being able to kill and injure top-level evolution beasts, but the consumption is not small, and it cannot be fired in bursts. Pen ~ fun ~ pavilion www.biquge.info

After each giant cannon is fired once, it needs to be cooled down for a day before it can be fired a second time, and for Wang Dong now, he can only look at it.

Secondly, there are sixty high-level energy cannons, of which there are ten in each of the four city gates, ten in the royal palace, and the remaining ten are distributed in various locations in the city, which are usually hidden in the turrets, and will only be raised when needed.

This high-level energy cannon is somewhat similar to a laser gun, but it is much more powerful than a laser gun, and it is a group damage, and is used to kill advanced evolution beasts and zombies.

Consumes crystal nuclei as an energy source, and although there is also a cooldown, the cooldown time is relatively short, and it only takes 30 seconds after each launch to launch the next one.

There are 400 intermediate-level energy cannons, 100 in each of the four city gates, which consume intermediate-level crystal nuclei, and because the energy of intermediate-level crystal nuclei is not very violent, there is basically no need to cool down.

There are group attack energy cannons, naturally there are single attack facilities, that is, arrow towers, arrow towers are also divided into giant crossbow arrow towers, advanced arrow towers and intermediate arrow towers, in addition to the number of energy cannons is twice as large, the location is similar to the location of the energy cannons.

However, the difference is that the energy cannon relies on energy attacks, dealing area damage, while the arrow tower is a physical attack, which is a single damage.

The two facilities have their own advantages and disadvantages, the disadvantage of the energy cannon is that it consumes more energy, as the saying goes, as soon as the cannon sounds, the gold is not a joke, a seventh-level magic core is put into a high-level energy cannon, and it will send out ten seventh-level strength attacks, and it will be destroyed.

The seventh-level crystal nucleus is even more unbearable, only three or four times, and the seventh-level strength attack is generally difficult to kill the seventh-level evolution beast, so it can only be injured but not killed.

But the advantage is also obvious, that is, the attacks of the energy cannon are all range attacks, and each energy bomb can cover a large area when it explodes, which naturally covers many enemies.

Naturally, the disadvantages of the arrow tower need not be said, because it is a single attack, although the number is twice that of the energy cannon, but when killing the enemy, it is not as good as the energy cannon.

And because it is a physical attack, the main lethality depends on the arrows shot by the crossbow on the tower, if there are no arrows, even if there is energy, it will not be able to attack, and the sharpness and strength of the arrows will also determine the power of the arrow tower to a certain extent.

The advantage is more obvious, that is, the energy consumption is very low compared to the energy cannon, for example, as long as there are enough level 7 arrows, a level 7 magic core is enough for a high-level arrow tower to shoot hundreds of attacks.

These are in terms of attack and defense, and in terms of control, this city in the sky is even more magical, it is like a legendary fairy cave.

In a secret room in the center of the palace, there is the control hub of the whole city, through which the entire city can be controlled, whether it is flying, levitating or landing, etc., all need to be controlled through the control hub.

Because the beastmaster at that time was a beast control clan, and he didn't want outsiders to control the city, so if he wanted to control this ownerless city, he needed to meet one condition, that is, the most basic and core skill of the beast control clan, the capture technique.

The ownerless Sky City is like a pet beast egg, as long as you leave your own spiritual power and then release the capture technique, you can control it as freely as a pet beast.

The entire city and some of the important buildings in the city are made of that magical metal, so at a critical moment, this city in the sky can turn into a giant metal behemoth like a transformer.

Because there are so many cutting-edge technologies involved, it took six or seven years to succeed in researching this function alone.

In the era when the evolutionary energy of the Pet Beast Empire was thin, there had been no saint-level powerhouse for thousands of years, so all scientific researchers, including the Beastmaster at that time, hoped that in the end, this metal giant beast could have the power of the saint-level.

Of course, they don't know if they can fight against saint-level powerhouses, after all, they don't know what the power of saint-level is, anyway, the power of metal behemoths is definitely not comparable to top powerhouses.

These are just some of the features of the city in the sky, and there are many more amazing features that can be found everywhere in the city.

If it weren't inappropriate, Wang Dong would have been impatient to exchange it, but it's not too late.

He knew that the model-like thing in his hand at this time was the Sky City, and the reason why it was in this state was because it was now ownerless.

There are no living creatures in the city, and the stored energy is very limited, so it can only be reduced by the current state. As long as you complete the confession of the Lord, you can change back to your original form.

Before, he only learned about the appearance of Sky City from Xiao Nuo's mouth, and it was the first time he had seen the real thing, so Wang Dong didn't care about waiting for a few women in the fight, and couldn't wait for the yuan to land on the ground.

Wang Dong, who landed on the ground, placed the Sky City in the center of the grassland, and then took out his saber from the inheritance space and gently slashed his fingers, allowing the blood red with a little bit of golden blood to drip on the basketball-sized Sky City.

I saw that as soon as the Sky City came into contact with Wang Dong's blood, it was like turning into a sponge, and all the greedy people sucked it in.

Then, according to the method of Xiaonuo's teaching, Wang Dong released a capture technique against the sky city.

When the invisible golden yellow circle of light of the capture technique landed on the Sky City, it immediately disappeared into it, and then Wang Dong felt that he had established a link with the Sky City in front of him.

This link was not much different from the connection between the pet beasts, and he felt that the city in the sky would also be like a pet beast, obeying any orders from him, and he knew that he had taken control of the city.

Wang Dong first rode the RMB into the air, then rubbed his hands excitedly, and tried to command the spiritual connection of the sky city: "Start!" ”

As soon as the order fell, the basketball-sized sky city suddenly began to grow, and the speed of this increase was very fast, and the buildings that were originally the size of soybeans quickly turned into buildings full of futuristic sci-fi style in just a few tens of seconds.

At this time, the city in the sky in front of him was no longer a city the size of a model, but a somewhat similar combination of an ancient city and a modern city.

The entire city in the sky is square, surrounded by a metal wall that is dozens of meters high and several meters thick in the thinnest place, and there is a huge gate on each side.
