November 17th, sunny!

After coming back from Chen Youyun last night, it was past three o'clock in the morning.

Back in his apartment, Ling Feng planned to go to Jiushi Mountain early tomorrow morning to step up his efforts to supervise the construction of the five military defense lines.

He woke up at half past eight in the morning.

After eating something indiscriminately, he hurried to the city airport, and teleported all the fighter equipment that the system had replenished today, and after he was done, he controlled the golden mecha and flew straight to the direction of Jiushi Mountain.

At about ten o'clock in the morning, he arrived at Jiushi Mountain.

At this time, 800,000 eighth-generation robots have all gathered in the Jiushi Mountain area.

At that moment, he teleported 50,000 robots into the arsenal, and then followed him into the arsenal.

Entering the Infinite Arsenal, Ling Feng directly ordered the 58,000 generation robots to frantically carry cement, steel and other building materials outside before the auxiliary shutdown.

Because, when the time comes, it is estimated that the construction materials of the five military defense lines will be countless times that of building underground shelters.

If he didn't prepare the building materials in advance, he was afraid that as soon as the auxiliary warehouse was closed, his plan might not be completed smoothly.

When Ling Feng's order was given, all of a sudden, fifty-eight generations of robots poured into the auxiliary warehouse one after another, frantically carrying various building materials outside.

Half an hour in the arsenal and millions of honorary achievement points were spent, and the area of the arsenal was again expanded by millions of square meters. In this way, his arsenal is even wider and more boundless.

After many expansions, the total area of the Infinite Arsenal is now at least tens of millions of square meters.

After withdrawing from the arsenal, Ling Feng began to lead a group of ninth-generation intelligent robots to select a site near Jiushi Mountain.

After several hours of exploring the terrain and environment, Ling Feng had identified the main sites for the construction of the military defense line.

With the underground shelter of Jiushi Mountain as the central point, it continues to extend outward. Every fifty kilometers. Build a huge military defense line on the site.

Within the defensive line, a large number of turrets, missile bases, logistics supply bases, strong fire defense walls and a series of military fortifications were built......

The five military defense lines, spanning 250 kilometers, will almost make half of Gandong Province smaller. All are circled within the line of military defense. Arguably. This is an unprecedented, extremely vast military project.

The manpower, financial resources and materials consumed by this project are simply incalculable.

Fortunately, Ling Feng didn't have to worry about these things. Because it has an auxiliary warehouse that can supply unlimited building materials, as well as millions of high-end intelligent robots.

With these two things, it is only a matter of time before our own military defense line is built.

After choosing the specific addresses of the five military defense lines, Ling Feng had no time to wander around.

Since half past one in the afternoon, he has been piloting the golden mecha, running back and forth in five planned construction sites, transporting the building materials that have been carried out of the auxiliary warehouse in piles and piles outside.

In a whole afternoon, he almost transported tens of millions of tons of steel and cement, and other construction equipment.

In the end, the fifty-eighteenth generation robots in the auxiliary warehouse, the speed at which they carried them could not keep up with the speed at which Ling Feng teleported outward, which made Ling Feng frown.

After learning that 50,000 robots were in the auxiliary warehouse and were a little too busy, Ling Feng sent another 50,000 robots into the arsenal and continued to help carry construction materials.

At the same time, the remaining 700,000 eighth-generation robots, they have already made a design plan for the military defense line under the leadership of the ninth-generation robots.

After showing the engineering design drawings to Ling Feng, he was very satisfied with the engineering design drawings made by these ninth-generation robots, so he gave an order, and all the robots began to work.

The first military defense line was built 250 kilometers away from the underground shelter, that is, the first military defense line, which was the farthest away from the underground shelter of Jiushi Mountain, and the scope and scale of the project were also the largest.

Basically, the area and scale of the first line of military defense can be equal to the sum of the work of the remaining four lines of defense.

The fifth military defense line is the closest to the underground shelter, only fifty kilometers away, and this range is basically within the core area of Jiushi Mountain.

Under the command of thousands of ninth-generation intelligent robots, 700,000 eighth-generation robots controlled various excavators, bulldozers and piling compactors to start a large-scale foundation construction project.

Ling Feng controlled the golden mecha, flying high in the air, through the video surveillance system inside the mecha, he could clearly see that the 700,000 eighth-generation robots were all scattered, like a circle of silver-white waves, surrounding the entire military defense area.

The five military defense lines that have been planned, within an area of nearly 1,000 square kilometers, are filled with countless steel, cement and other construction equipment.

In particular, the stacking area of steel and cement is the broadest, Ling Feng preliminarily counted that within nearly 1,000 square kilometers, other building materials are not counted, and the number of steel and cement stacked alone exceeds tens of thousands of piles.

In each pile of steel and cement, there are thousands of tons and hundreds of tons, all of which are like hills tens of meters high, piled up around the construction sites of each defense line.

Thanks to the addition of 50,000 robots to help in the auxiliary warehouse, they are now more than twice as fast as they can move building materials.

At the current speed of transportation, they can move enough engineering materials from the auxiliary warehouse to build five military defense lines within three days at most.

However, although the problem of materials was solved, in the face of such a terrifying and huge military project, Ling Feng suddenly felt that fortunately he now had millions of intelligent robots, and without these robots, it was estimated that he would not be able to do anything.

When it comes to working ability and work efficiency, an eighth-generation intelligent robot is worth at least hundreds of ordinary humans.

And as long as Ling Feng gave them an order, these robots would work day and night without eating, drinking, or sleeping, and would not give up until the task was completed.

What makes Ling Feng even more satisfied is that these robots will not complain, will not be lazy, and will not cut corners and cheat. Moreover, in their work, there will basically be no mistakes and wrong rework, which greatly accelerates the progress of the project.

How strong is the working ability of these eighth-generation intelligent robots? It is estimated that most people do not have a very clear concept.

Here we can make a very simple comparison.

Take the example of transporting cement from the auxiliary warehouse to the outside munitions warehouse, which is about 100 meters away.

A normal adult man, he carries one bag of cement out at a time, and estimates the workload of a day, at most two hundred bags of cement, which is ten tons of work.

But an eighth-generation robot, its maximum speed is more than 200 kilometers per hour, it can lift at least four bales of 50 kilograms of cement at a time, and then as long as it takes a few seconds, it can successfully move all four bales of cement.

Basically, in a minute, these eight-generation robots, they can run six back and forth, move out more than a ton of cement, more than a ton a minute, seventy or eighty tons an hour, 24 hours a day, they can carry out more than 1,500 tons of cement without stopping.

It can be seen that these eight-generation intelligent robots, how terrifying their work efficiency is, if you really test it, it is estimated that more than 100 adults, in terms of physical work, may not be comparable to them.

Therefore, although Ling Feng's current construction of five military defense lines is very huge, it is not particularly difficult for these robots to complete it before the advent day.

After all, if 700,000 eighth-generation robots are rushing to work day and night at the same time, the speed of progress of the project is very terrifying.

However, Ling Feng was still a little worried, because today was already November 17, and it was only a month before the advent of December 17.

He wants to complete these military projects as soon as possible, as soon as possible! In the end, it will be completed before December 10, and in the remaining seven days, he will still have to install and deploy various weapons and equipment on five military defense lines.

Therefore, in order to complete the five military defense lines as soon as possible, Ling Feng recalled another 100,000 robots scattered in other provinces and cities through his mind.

After adding another 100,000 eighth-generation robots, Ling Feng has invested 900,000 robots in the construction of five military defense lines.

In a few days, as soon as the auxiliary warehouse is closed, all the 100,000 robots inside will come out for construction.

At that time, the speed of the huge project of the military defense line may increase considerably.

In addition to the 900,000 robots that built the defensive line, he only had 100,000 eighth-generation robots left.

Of the 100,000 and 80,000 robots, there are 20,000 or 30,000 people stationed at twelve military bases on the south bank of the Hengjiang River. For the remaining 70,000 robots, Ling Feng let them continue to collect supplies in various provinces and cities in the south.

Anyway, after the federal government retreated to Jiangbei, a large amount of weapons, equipment and ammunition were left behind in many military bases in the south.

There are many large artillery pieces among them, and when the time comes, he will order those robots to dismantle all the artillery and missiles in the large artillery bases scattered around the country and transport them to his military defense line.

After the five military defense lines are all successfully completed, the weapons and equipment in his unlimited arsenal, plus the large artillery collected from various military bases, are all deployed within the five military defense lines, and at that time, the entire armed defense of the underground shelter of Jiushi Mountain should be able to reach a terrifying level.
