After returning to the warehouse in the backyard of the villa from the arsenal, Xu Yuan began to transport the equipment that Ning Hui had bought.

2 engineering robots, a deep-sea submersible with a maximum capacity of 4 people, and an engineering module and mining module that can be mounted on a deep-sea submersible.

This engineering robot is a good thing, according to the engineering information downloaded on its smart chip, it can automatically complete the preset project, although the speed of automated construction may not be as good as manual control, but it is better than precision and convenience.

After returning to the present world.

Xu Yuan drove the speedboat alone to a deserted island located in the east of the main island.

One of the advantages of the Lucas Islands is that there are many islands, and because of the 10 billion dollar project, most of the uninhabited islands in the country of Qatar are under his name, including this uninhabited island called "Stone Island".

Xu Yuan first moved two engineering robots and drone terminals.

Although it is only 1.5 meters tall, it looks a little dull, but it is not ambiguous at all when it does its work.

Like the three heads and six arms in the myth, each arm is mounted with a series of tools such as welding torches, cutters, and multi-function wrenches.

The half-track, half-walking chassis also allows it to move quickly on flat ground and cross all terrain.

First, a drone terminal was placed in the dense forest in the center of the island, and Xu Yuan released 20 drones to scan the island, which is only one square kilometer, and then logged the holographic map information on the tablet of the control engineering robot.

After completing the data transmission, he made several more trips back and forth, moving the components of the deep-sea submersible, the drone terminal, the solar generator, and some steel and cement building materials.

Then Xu Yuan stretched out his finger and first marked the place where the materials were stacked on the island, and then clicked on a location on the higher part of the island on the three-dimensional map to set up the construction project of the solar panels.

I saw that the two engineering robots immediately turned the tracks of the chassis, and after arriving at the designated position, they skillfully began to erect the solar generator.

After just waiting for 15 minutes, Xu Yuan watched with satisfaction as the two robots completed the work at hand.

There was an exclamation in his heart, Xu Yuan sighed incomparably, this is fully automatic to complete the construction work, so that building a house is as simple as stacking blocks, if this technology comes out, I don't know how many builders will go crazy about it.

Of course, Xu Yuan will not push it to the world in a short time, and the real good things still have to be pinched in his own hands, and it is better to throw them out when he is tired of playing.

Holding the tablet in his hand, Xu Yuan then set up the two robots to connect the wires to the drone terminal to charge, and then deployed a dock project to be built on the seaside, and at the same time included the task of assembling the deep-sea submersible in the construction queue.

After confirming that there was nothing missing, Xu Yuan turned off the tablet, and then only needed to wait for the construction to be completed.

In order to ensure the safety and confidentiality of the island, Xu Yuan pondered for a while, and finally decided not to send soldiers here.

This wasn't because he didn't trust his subordinates, but because he was worried that those with ulterior motives who were watching the Star Wish Trading Company's movements might notice it.

And once the island is stationed with living people, it means that supplies will be constantly sent to the island, which will weaken the secrecy of the island, at least until the construction of the engineering robot is completed, the island is better kept secret.

So for now, drones are the most suitable for security guards.

Back at the drone terminal, Xu Yuan changed the drone's behavior procedure from reconnaissance to vigilance.

As soon as the drone detects that a vessel is approaching, the built-in signaling device communicates the alarm to his GS.

After doing all this, Xu Yuan returned to the source star.

However, as soon as he returned, a crackling sound reached his ears.

After being stunned, Xu Yuan hurriedly rushed to the side of the wall!

Standing on the wall and looking around, the dense radiant beasts were squeezed into a ball.

This scene could only be seen in the city, but now it is in the quiet suburbs.

No one knows why the Radiant Beast Tide has erupted, most likely, foraging.

Of course it doesn't matter, it's how to solve them.

Such a desperate scene makes it difficult for any viewer not to feel numb in their scalps, this twenty-meter wall actually does not bring more security to people, because there are too many radiant beasts below!

Outside the walls, a group of drone attack groups cruised low altitude, shooting the radiant beast in the head with a mounted small-caliber rifle.

In addition, there are soldiers in heavy all-angle body armor crouched behind the walled bunkers, carrying canisters full of organic synthetic fuel on their backs and spray guns in their hands, ready for possible flying xenomorphs.

Whether it's a light infantry with a rifle or a fireman with a machine gun, all combat units on the wall have only one mission.

That is to do everything possible to kill the radbeast at a distance from the base.

Just when Ning Hui was looking at the corpses with a frown, Xu Yuan climbed the wall, looking at the situation outside, he was a little incredulous.

He had only been away for less than a few hours, and he didn't expect the situation to deteriorate to such an extent, looking at the endless tide of radiation beasts in the distance, he suddenly felt that the entire manor was like a lonely boat.

Ning Hui on the side frowned, extremely irritable.

You must know that if you want to make a steep slope on the twenty-meter wall, that is, ten thousand radiant beasts, and the various radiant beasts coming from the outside are not only tens of thousands? It's a bit less than a million to say it's a million.

In order to stop the human ladder tactics of these radiant beasts, the soldiers on the wall ripped off their hands and threw them at the dense area of the radiant beasts on the wall.

But this method is not a cure for the symptoms after all, even if it can cause objective damage to the radiation beasts gathered together, but those corpses are still piled up under the wall after all.

"What about the mortars in the base?" Raising the telescope to observe the distribution of radiation beasts in the distance, Xu Yuan asked casually.

"It's ready." Ning Hui replied.

Mortar ammunition is not unlimited, the manor's reserve is less than 5,000 rounds, and the mortar bombardment efficiency is the highest only when the radiation beasts outside have formed an absolute number and density.

"How many shells can a military factory produce per day?" Xu Yuan asked Ning Hui beside him.

"If the supply of materials is sufficient, the maximum production capacity is 100 rounds." Ning Hui replied that the production of mortar shells is very complicated, and besides, the military factory is not making shells all the time, and other things are also needed!

Xu Yuan touched his chin and pondered, do you want to get something from the present world, this 100 production is estimated to be not enough for one round of shooting, it is obviously not enough.

At this time, the corpses under the wall had been piled up two or three meters high, and seeing that the time was almost up, the survivors climbed the wall with fuel canisters and began to pour fuel under the wall.

A few cans of fuel went down, and the survivors threw torches under the wall.

The flames suddenly rose into the sky.

Smoke rose from four directions, enveloping the manor.

The soldiers put on gas masks, while the survivors fled the fence with their mouths and noses covered.

The smoke emitted by the fuel itself is very small, but the opposite is true for the radiant beasts that are burned together.

I have to say, these bed bugs really stink when they burn!
