Chen Yue knew very well in his heart that it was not easy to defend a planet. Especially when your own strength is at a great disadvantage.

And there is a difference between defending a planet and "getting supplies from it."

The former is nothing more than ensuring that the planet is not occupied by enemies. The latter also has to protect the planet, stop most of the enemy's incoming attacks, and then build mines and factories on this planet.

The latter is undoubtedly several times more difficult than the former.

But at this moment, Chen Yue must do the latter. Otherwise, it doesn't make sense for him to occupy the planet at all. The remaining tens of thousands of warships will all be lost here, and the entire grand strategy of human civilization will be completely disrupted.

At this moment, tens of thousands of warships on our side and more than 10,000 warships of the coalition forces are fighting fiercely in the three-dimensional space of 100,000 to 3 million kilometers away from this planet. At this stage, Chen Yue no longer pursued to inflict damage on the enemy, but began to pursue the interception of the enemy's pouring artillery fire in order to provide sufficient protection for the planet.

Under such circumstances, a large number of ferry ships began to be released from the inside of the battleship, and under the cover of the battleship, loaded with a large number of mechanical equipment and robots, began to land on the planet.

Sensing this, the coalition artillery fire immediately went crazy again.

Be sure to stop the enemy from building industrial facilities on this planet! Otherwise, the planet is really lost!

Once again, the battle is heating up. A large number of ferry ships had just left the battleship before they were destroyed by artillery fire. But there were too many of them, and under the desperate cover of the human fleet, a large number of ferry ships still landed on the surface of this planet.

The hatch opened, and immediately, a huge number of robots poured out like a torrent of steel.

With the help of the protection of the energy shield on the ferry spacecraft, these robots were quick with their hands and feet, and with a very tacit understanding, they took out another set of energy shield generators and quickly assembled them. Immediately after connecting to a dedicated modular small fusion power plant unit, a larger energy shield was propped up, protecting a piece about the size of a football field.

Something like this is happening everywhere on this planet at the same time. In this extremely short period of time, more than 30,000 energy shields were propped up.

Every moment, a large number of energy shields are broken by attacks from space, and the robots are destroyed in an instant, but every moment there are also ferry ships from space, transporting the new energy shield generator and robots to support the new energy shield again.

On one side is destruction, and on the other side is rebirth. Moreover...... Rebirth is much faster than destruction!

In just two days, the number of energy shields that were propped up had skyrocketed to 50,000, and it was still increasing rapidly!

Not only that, but these places where the energy shield is held up seem to have been deliberately chosen. After long-range detection, Hongshan and Luvent were somewhat surprised to find that the enemy seemed to have already planned their own industrial system.

Some of these energy shields occupy mineral collection points and can collect iron ore, copper ore, tin ore, phosphate ore, etc., while some energy shields are located near the mine and seem to be mineral primary processing devices built nearby, and some larger energy shields are built in the plain area, which can maintain relatively convenient transportation with the surrounding energy shields......

"Are they so confident that they can build an industrial system? Too arrogant, too arrogant, right? ”

The two of them were suspicious.

In the close attention of the two, something even more amazing happened.

One was under the energy shield of the copper mine, and the two of them were shocked to see that the day before it was still a white field, empty except for the energy shield. But by the next day, a lot of machinery had been set up. On the third day, there was black smoke coming out of it, and mining had already begun!

It only took two days to build a set of mineral collection devices!

How is this possible!

Although it is common to adopt modular units on the battlefield to speed up the assembly of machinery as quickly as possible. But even with a modular device, it can't be so fast!

Luvent knew in his heart that his fleet was well-trained, and the most elite Field Resource Legion would take at least ten days to set up a mineral gathering device and put it into operation, on the basis that the energy shield could provide complete defense. Now, how is it possible to start mining in two days?

How did the enemy do it?

Under the orders of the two commanders, the fleet's intelligence detection system has once again increased its observation of the planet's surface. So soon after, an extremely shocking scene was presented in front of the two.

Robot! Lots of bots! Countless robots!

The dense robots are like ants, walking and shuttling through the construction site like flying. They are so powerful that they can lift thousands of pounds of weight and even fly. They work together so well that the entire huge construction site looks like a mess, but if you look closely, you can't even see a single mistake!

There are no collisions, no progress delays, no laziness, no fear, all robots are running fast and precise like clockwork on a precision machine......

A robot rushed out of the warehouse at a speed of hundreds of kilometers per hour, rampage all the way, and none of the tens of thousands of robots passing by on the way blocked the road, and their respective speeds did not decrease;

When the robot arrived at the place, it threw the metal box in its hand at will, and there was no one in front of it, seeing that the box was about to smash to the ground, but in a blink of an eye, another robot with a speed of hundreds of kilometers per hour happened to come here from the other direction through the surging crowd, just caught the metal box, and then rushed to the next place without stopping......

Dozens of robots rushed together towards a semi-finished large machine, the first robot directly laid a spacer, 0.1 seconds later, another robot just arrived, put a bearing on it, and 0.1 seconds later, another robot installed a crankshaft......

In just a few seconds, as if by magic, a large machine was assembled. The next moment, without anyone to operate, it began to roar on its own, and the huge special alloy bucket dug down fiercely, and there were dozens of tons of ore at once, and quickly turned around and fell to the side, and a giant truck happened to stop under the bucket, catching all the dozens of tons of ore......
