With a heavy heart, Li Hao returned to the Royal Academy of Sciences.

During this time, it was not only the Cabinet that led the construction of the Great Wall of Space.

The four chief scientists of the Royal Academy of Sciences, the strategic weapons jointly developed have also been developed. Intensive experiments are being carried out.

It was the success of their own strategic weapons that gave Li Hao the confidence to block the attack of the Yuanji civilization.

Otherwise, light can defend, and offensive ability will not work. Nor can they change the fate of failure.

Li Hao knew that the ancient ancestors of the earth wanted to rely only on the Great Wall for defense and get by. There are no means of attack. The fate of these dynasties was miserable.

Li Hao walked into the Royal Academy of Sciences and saw Bi Ye and they were also happy to come back on the spaceship.

He greeted Bi Ye happily: "Mr. Bi, what are you doing?"

"Your Majesty, let's go and install the Sky Cannon in the Shuangdan Fortress, and test the power of the Sky Cannon there. The research and development of the air cannon has entered the final stage. Bi Ye explained.

"You went to the Shuangdan Fortress, I didn't go today. Just look at the edge of the space for a moment. It's good that the air cannon is stabilized. This is also a big step forward. Li Hao said happily.

The Shuangdan Fortress is the only way they can connect with the outside world, and it is also the only place where they can fight the Yuanji civilization.

The Sky Cannon is a strategic weapon developed by the four chief scientists over a long period of time.

The establishment of the Shuangdan Fortress, which was through their detailed discussions, had to be built.

Two of the important reasons can directly prompt them to build the Shuangdan Fortress.

Without the Shuangdan Fortress, they would be completely cut off from the outside world. They will not be able to communicate with the outside world in space.

The door of their strategic-level technological space can only move in the small space inside.

And because of the problems with the giant black hole, they don't leave a strategic channel. It is easy to be wrapped into a dumpling filling.

Besides, don't leave a channel for the Yuanji civilization to attack. If they vent randomly and really cause irreversible consequences, it will not be good.

For example, they try to destroy giant black holes.

Li Hao and Bi Ye walked into the Royal Academy of Sciences. He said directly to Bi Ye: "I want to know about the current situation of the Sky Cannon."

"Your Majesty, we are about to finalize the mass production of the Sky Cannon, you can come and listen to it. Through this, you will have a basic understanding of the Sky Cannon. Bi Ye introduced.

Li Hao nodded and said, "Okay, I'll listen to what the effect of your improved Sky Cannon looks like."

He entered a conference room with Bi Ye, and it didn't take long. Li Deren, Du Xianyu, and Guo Jianmiao all walked in with the information.

When they saw Li Hao here, they all greeted him respectfully.

Li Hao nodded and said, "I'm just here today to see the performance of the Sky Cannon, just do your part." Don't worry about me. ”

Bi Ye got up, and he said in a loud voice: "We have jointly developed the Sky Cannon.

Each of us has a slight difference in the direction of the development of the Sky Cannon. For the sake of a huge threat to the Yuanji civilization.

According to the situation of the cannon, we began to improve the cannon, according to the scientific and technological route we knew.

Let me introduce you to your own cannon. ”

After Bi Ye finished speaking, he used the light curtain to show his empty cannon.

Tens of thousands of kilometers of air cannons, spanning a huge space.

With one shot, the surrounding space turned into nothingness. The range is within a radius of one light.

"The air cannon I developed is a route of great power. With one shot, everything will be destroyed.

Even if the Sky Cannon can't cause fatal damage to it, the Sky Cannon will also wipe out the surrounding space.

I left the enemy with no place to retain, and the space around me disappeared. They are also trapped in the void.

I experimented with a neutron star, and it was hit by a cannon in the sky. After shattering, it was swallowed up by the void space. After quantum computer calculations, the members of the Yuanji civilization could not withstand this blow.

My cannons are named Type A cannons.

His main disadvantage is that it takes a lot of time to prepare and uses a lot of energy.

It should not be used frequently in one place, and the space in one place should be repeatedly annihilated. It will cause violent fluctuations in space, causing some extremely dangerous things to happen. ”

After Li Deren sat down in Bi Ye, he got up and said: "The Type B air cannon I developed belongs to the air cannon based on fine strikes."

After Li Deren finished speaking, he played the video he showed.

After a spatial distortion of energy was released, the stellar-class battleship in front of it seemed to be made dumplings.

Trapped by the sudden roll-up of space, it seems to fold a three-dimensional picture into two dimensions. Like a painting on paper, it comes to life.

Li Hao stood up suddenly and said in shock: "This, this is the two-way foil in science fiction."

"It's not a two-way foil, it's far worse than a two-way foil. The range of use is too small, only tens of thousands of kilometers.

The use also requires the extraction of space subtons, which is the relationship between space and void space to leverage the energy of space. Li Deren said modestly.

"My C-type cannon was the latest to be developed, but it was the most powerful one.

It acts with the coherence of forces between space and nothingness. Transform the space sub to speed up to 50,000 times the speed of light.

It's like a god blocking a god, and no matter can resist the power of this weapon.

This is our ultra-long-range attack weapon.

The only problem with it is that it is not controlled, and after it is launched, it is impossible to control it at all. You can only go straight. Du Xianyu said excitedly.

He then demonstrated the power of the C-type cannon.

It hits the large black hole with a beam of energy, directly penetrates the large black hole, and it also begins to emit energy outward.

Li Hao applauded excitedly: "This is really an important weapon of the country." Kill the enemy tens of thousands of light-years away. ”

He asked Guo Jianhao: "Mr. Guo's must be a D-shaped air cannon." What is it capable of. ”

Guo Jianhao said with a smile: "Mine is indeed a D-shaped air cannon.

I am not taking the research route of killing, but the line of defense. ”

Li Hao said in surprise: "The air cannon can still be defended, it is not an offensive strategic weapon."

Guo Jianhao also turned on the light curtain, and a dragon-class battleship was played on it.

A small tube stretched out from its body, spewing out a light curtain that soon covered the entire hull of the Dragon-class battleship.

The Dragon-class battleship of this experiment withstood the siege of Star Destroyers from other Dragon-class warships.

Li Hao's applause rang out again, and he exclaimed: "Mr. Guo's achievements have found a new way, which is really good."

Guo Jianhao said confidently: "Of course, the three of them all chose a powerful direction. I don't think the defensive aspect is well thought out.

I developed the defensive direction, and I finally developed the D-shaped air cannon. Its mezzanine has a void space, and no particles and energy can penetrate it, and safety is guaranteed. ”
