Yi Xiaojing's body was as light as a feather, floating in the air.

Holding a square box in his hand, he threw it to the ground.

After the square box touched the ground, it exploded instantly. In an extremely sci-fi way, it expanded rapidly, but in breathing time, a production line more than 800 meters long and more than 100 meters wide appeared in front of Yi Xiaojing's eyes.

As the metal matchboxes were thrown down, in this col above the island, a very sci-fi production line appeared neatly arranged.

Ark reactors and tall buildings are rising from the ground, and they will meet the energy consumption of these production lines in the production process.

With the establishment of the production line, engineering vehicles were driven out of the plant. One by one, the robots went in and out, without a moment's delay, and immediately began to work.

In just ten minutes, on the island that was still very wild just now, there are already hundreds of high-rise buildings, and all kinds of vehicles, aircraft, and robots frequently enter and exit, just like a science fiction world.

"There's only one left."

Yi Xiaojing took out the basketball-sized space compression production line.

Qin Chuan specifically instructed that this production line covers a huge area, I am afraid it must be 30 square kilometers in size. It is said to be an orbital light cannon production workshop, in fact, the technology content in it is extremely high, and all kinds of other weapons can be completed in it, and even some automatic production lines for firearms can be produced in it.

Yi Xiaojing found a plain on the island and threw the metal ball towards the ground.

"Squeak~"

"Hiss ······"

On the plain, some animals seemed to sense the danger coming, and they ran quickly one by one.

Some of the seabirds flapped their wings and fled quickly towards the sky.

"Boom!"

There was a loud bang.

Unlike other production lines, it expands quietly. The production line of the railgun exploded rapidly and vigorously, and expanded rapidly.

The huge factory building covering thirty square kilometers expanded rapidly in all directions at a lightning speed in a dark blue electric light.

After a dozen breaths, the expansion stopped.

The dark blue, electric light like water waves receded, and what appeared in front of Yi Xiaojing's eyes was already a factory more than 800 meters in the middle, gradually getting lower and boxy towards the surroundings.

The highest place was already higher than the height at which Yi Xiaojing was floating at this time, and more than 200 meters higher than the highest mountain on the entire island!

"It's so conspicuous that you can see it hundreds of miles away! When a satellite passes by in the sky, it can be easily scanned! ”

Yi Xiaojing shook her head and bounced the metal ball the size of a glass bead in her hand towards the sky.

"Click~"

In the midst of a few slight metallic sounds, the metal ball activated and expanded, turning into a projection. Under the effect of anti-gravity, one floated to a height of a thousand meters and cast a curtain of light in all directions, enveloping the entire island.

"Scan the surrounding environment, and then cover it through a light curtain to block the sight of outsiders, so that the whole island is hidden."

Yi Xiaojing rose hundreds of meters, and after going out of the range of the light curtain, he looked down, and the real island had disappeared, and in Yi Xiaojing's naked eyes, there was only a calm sponge, under the sun, glowing with phosphorescence.

"Brain!"

Yi Xiaojing shouted.

"Deep Blue obeys, sir, please command!"

In a crisp female voice, a projection wearing a slim military uniform appeared in the void and bowed towards Yi Xiaojing.

"Deep Blue, send out a couple of patrol boats outside the island. I have already said hello to countries that have territorial sea rights here, and no one will come.

If someone from another country intrudes into the island by mistake, don't kill them, don't leak the news! ”

"Yes, sir!"

Deep Blue Collar.

Yi Xiaojing returned to the island, glanced at the robots coming in and out, and walked into the various production buildings.

In this long building, every step is in a factory grid.

Detectors that automatically detect resources have already flown out, or burrowed headlong into the sea, or into the depths of the islands. Quickly detect a large number of resources.

The use of resources and energy in the science fiction world has reached a limit.

The automatic collection vehicle quickly collects the shallow resources back and enters the various factories for refining.

Soon, countless pulsed bullets flowed out like flowing water. On the production line of pulse rifles and plasma guns, parts appear one by one, and robots are rapidly assembling.

"At this rate, about 30,000 pulse rifles and plasma rifles can be produced in a day."

Yi Xiaojing looked at the brain light screen in front of her.

In addition to the production data of various aspects, the light screen is listed on it.

"The production of automatic cruise guns is slower, it takes about two days to produce one."

This automatic cruise cannon is somewhat similar to the automatic cruise robot of the Iron Eater Beast Clan. It is in accordance with the regulation of the brain and within the specified range, patrolling is carried out. Among them, the energy of the pulse cannon is very ferocious, and if it can hit, it is enough to cause damage to the monks of the Yudan realm.

Secondly, there are also two hidden mechanism plasma guns on the body of the automatic cruise cannon, which have fierce firepower, and can cause a powerful deterrent effect against ordinary martial artists, even if they are martial artists in the Xuanwu realm.

This is what Yi Xiaojing values the most.

It is placed within the scope of Zhongzhou City, which is enough to protect the safety of Zhongzhou City at this stage.

The rest of the mecha production, exoskeleton armor, robot army, magnetic cannon, and even orbital light cannon, if Zhongzhou City is equipped, then the power of Zhongzhou City will reach a new height!

After leaving the production building and arriving at the beach, Yi Xiaojing saw that many robots were thrown into the sea, automatically changing their shape, and becoming underwater robots, automatically precipitating a lot of useful minerals in the seawater.

"On this day, the production line will be placed in the anti-Japanese world first."

The resources of the anti-Japanese world have not yet been developed, and all kinds of resources here are still abundant.

"I'll come back in two days."

Yi Xiaojing's figure flashed and left the anti-Japanese world.

I walked to various worlds, but there was still no news of the dragon and tiger.

Although there is some disappointment, it is also unhurried.

In the following month, Yi Xiaojing began to formally study the Cuiyun Mountain Flying Sword Technique, and often traveled to various worlds to inquire about the two qi of the dragon and tiger, and at the same time, he also brought back the materials collected by various worlds to refine the flying sword.

In this month, Zhongshan City has changed a lot.

In the sky above the steel city wall, more than a dozen round, one-meter-square flying machines circled around the city wall every day.

Many people were curious about what this round and cute thing was, until one day, when a warrior from the Xuanhuang world came to the city and intended to rob an earth woman, this round ball fell from the sky······
