"So young?" Xu Xin was a little surprised.

There is a missile mounted on the launcher, and the length of this missile is even more than one meter.

"It's just a test product for now. We will make a large-scale one in the future. As for the large-scale production, we leave it to Zeng Tao." Ma Hongwei explained.

Zeng Tao's ability is to make large-scale weapons.

"That's right."

Xu Xin nodded.

Zeng Tao is now very skilled in weapon development. Using her abilities, she can easily carry out large-scale research on the weapons developed by Ma Hongwei.

"According to your requirements, the firing rate of this launcher in conjunction with our missiles can already reach a maximum of about Mach 50 in the surface atmosphere. But correspondingly, because the main fuel is used for explosive push, the missile has a large range

The amplitude decreases, and if the target position exceeds 100 kilometers, the accuracy will decrease significantly."

In other words, this is a missile that greatly enhances its flight speed at the expense of range.

This is also the weapon that World Tree needs most at present.

No matter how far the range is, it will have no effect on this extremely huge planet.

Because their missiles cannot cross half a planet to attack alien invaders. Even if they have this range, if the opponent has an anti-missile system, it may not have any effect.

Therefore, what they focus on developing is "defensive weapons."

They want to ensure the safety around the World Tree. This kind of missile with short range but extremely fast speed and almost impossible to counterattack is the weapon they need most at the moment.

Achieve an irreversible blow to the surroundings of the World Tree.

Mach 50, a speed of fifty times the speed of sound, this speed is already very impressive.

You know, thousands of years ago, missiles that could exceed Mach 5 in the atmosphere could be called hypersonic missiles.

Mach 50, very exaggerated.

About 17 kilometers per second.

Even if the missile is launched outside the World Tree, if a person is inside the World Tree and observes it with a time velocity difference of a hundred times, the speed is still half Mach.

In other words, if you launch a missile inside the World Tree and look outside the World Tree where time is almost stagnant, you can still see that the missile is launched at a speed of more than 170 meters per second and a speed of more than 600 kilometers per hour.

Even if it is slowed down a hundred times, it will still be close to the speed of a commercial airliner.

Xu Xin felt that a missile of this speed should be impossible to intercept.

For defense, it is completely sufficient.

If there are cores inside...

"This way, I feel relieved for the time being."

Xu Xin felt that for the first time since the monster came, he felt a little relaxed.

"I'll try my best to finish it within two days, and then I can hand it over to Zeng Tao to be enlarged."

Xu Xin nodded.

Then he touched his chin and looked at this compact missile.

This kind of pocket size seems to be able to be carried...with you anywhere.

Although small missiles can hold much less ammunition, if they are nuclear, their power cannot be underestimated.

If one day they really want to sneak into the other side of the earth to destroy the scarlet crystal, this missile may be of great help!

"You haven't had any rest today, so go to bed early. Don't hang yourself with purple oranges all the time. Those things are not good for your health." Xu Xin stood up.

Oranges above blue level are used to refresh the mind by overdrawing life. They have already told all the survivors in the world tree about this. At present, these people basically no longer eat blue level fruits.

Purple-level fruits and above are much less harmful to life span. In addition, the resources in the World Tree are now very abundant, so purple-level fruits have become everyone's first choice.

But you can't eat it often. Although it will give you some powerful abilities at the moment, it will still have an impact on your lifespan.

"Don't worry, Brother Xin, I am a person who has been injected with genetic medicine. My life span is very long. Making weapons is more important."

Ma Hongwei couldn't get enough of it, so he turned around and continued to invest in research.

Xu Xin shook her head helplessly, stopped disturbing him, and came down from the tree house.

"ah--"

In the distance, the pterosaur Huihui is gliding towards this side at an extremely fast speed.

A few seconds later, it landed next to Xu Xin and rubbed its big head against Xu Xin's body.

"Hey!"

Coco, who was lying on Hui Hui's head, jumped down and jumped onto Xu Xin's shoulders.

"Have you had enough fun?" Xu Xin rubbed Coco's little head.

"Hey!"

This little guy often comes out to play with Huihui recently.

The injury that Huihui suffered last time has long been fully recovered without any traces.

"I'm going back and will see you next time."

"ah!"

Xu Xin brought Coco to a coordinate.

He reached out and touched the coordinates, the purple-black vortex condensed, and the portal appeared.

Xu Xin stepped into it.

After the world was spinning, he appeared at the very edge of the inner world of the entire World Tree.

The endless high wooden wall represents the end of the world.

And here, there are three tree houses, each of which is a three-story tree house, with a single-story area of ​​400 to 500 square meters.

They are all very big treehouses.

"Xu Xin, is something wrong?"

The window of one of the tree houses is open.

The monster's ugly head with eyes appeared in the window frame.

Because there was no one else around at this time, the monster no longer only opened the two eyes on its face like before, but opened all its eyes.

The eyes do not blink simultaneously, but sequentially from left to right. The eyes on the monster's upper body exposed from the window are surging like ocean waves.

This made Xu Xin feel a little physically uncomfortable, and the corners of his eyes twitched slightly.

"Ugh..." Coco shrank her head and closed her eyes.

"I heard your experiment is about to succeed."

Xu Xin looked at the monster and said.

"What, do you want to stop my experiment?" The monster's weird voice deepened slightly.

"Of course not. I'm just curious as to how far your experiment has progressed. Are you really going to create a race?"

The monster lives in the outermost area, and an important point is that it continues its experiments here.

This was actually the condition for Xu Xin and Xu Ying to agree to it.

In the World Tree where time flows at a hundred times the speed, give it an area and let it continue its experiments. In exchange, it cannot take action against the humans in the World Tree.

"...it is so difficult to create a race."

The monster disappeared into the window frame, and then a purple-black vortex instantly formed in front of Xu Xin, and the monster walked out of it.

He appeared in front of Xu Xin almost instantly.

"Hey!" Coco was startled and hung directly behind Xu Xin, with only half of his head exposed to look at the monster.

The monster did not pay attention to Coco, but continued: "However, although it is difficult, I have taken the first step. I awakened one of them."

"It has a clear consciousness, but unfortunately...like me, it does not have the ability to reproduce."

Xu Xin was immediately surprised: "Has anyone come back alive?"

He looked at the three tree houses: "In the tree houses?"

"Well, I've already fallen asleep." The monster's mouth split open, as if smiling, "My first kin is in good condition."

...it actually worked!

"Awesome." Xu Xin praised it sincerely, and then said, "I won't watch anymore. I'm here to tell you that the petrified creatures are coming soon. What do you want to do?"

It is the one that controls petrified creatures.

"I will hand over the command of the petrified creatures to you." The monster said immediately, "This is the first gift I give you."

Xu Xin smiled slightly.

It seems there is no need to waste any more words.
Chapter completed!
