After the death, about 8,000 unknown heads were wiped out, and the unknown landing was perfectly blocked, which was the biggest result since the start of the war, but the expression on Cao Chuan's face remained unchanged, because it was only half an hour later, more nest types tried to land.

More than 50% of the nest types successfully completed the landing and gathered at the North Pole, and the rest were scattered in other places for various reasons, even sinking into the sea of sand.

During this period, the fortresses under the jurisdiction of White Lotus continued to counterattack, and one after another beams of light frequently penetrated tens of thousands of kilometers, intercepting several times the scale of the unknown, although the defense force of Planet 3 showed great heroism, these fortresses still collapsed one after another explosions.

A week later, the ground was full of debris and broken walls, more than 150,000 unknown deaths, more than 200,000 unmanned units were destroyed, and as many as 10 spaceships were turned into ceremonial flowers, and more than 20 fortresses were turned into glass slags, which is the most intuitive change left by the war on Planet 3.

The war is still going on, and from time to time new forts are built and destroyed in the conflict zone, and every now and then new nests attempt to conquer the area, only to be destroyed.

The two sides come and go, for the time being, there is no sign of who wins and who loses, the unknown side destroyed nearly one-third of the defense force on Planet 3 in the early days of landing, and even destroyed the largest external airport of the base, with the arrival of support from Planet 2 and Planet 4, the joint production plant hidden underground on Planet 3 exploded productivity, the strength gap between the two sides was shortened, and the fierce conflict eased, resulting in the next wave of outbreak brewing on both sides.

In the sand, Qiao Yishan led the tactical squadron around on missions, and they continued to emulate what the expeditionary corps of the combat department had done on Pluto. The nuclear bombs of 500 million yield, 1 billion yield, and 5 billion yield were buried in the ground, and through the most direct explosion, three huge unknown nests were destroyed one after another, and more than 50,000 unknown heads were buried.

"When is the end of such a day?" Qiao Qianshan looked into the distance. In their field of vision, they can always easily find unknown traces, which shows that the unknown has penetrated into the planet to the extent that it is terminally ill.

"For us, though, it's the most efficient way to go." Qiao Qianshan thought, do you want them to complete the charge on the frontal battlefield like an unmanned unit? It's not that it can't be, it's a problem. They are such a small person, if they are used to charge, but they will die in a while, and they will die worthlessly.

"I don't know when the follow-up support will come, but when the number of soldiers here exceeds 100,000, it will be possible to start a frontal operation."

Qiao Yishan could imagine what it would be like when thousands of warhammer mechs broke through the earth and ran wildly in the wilderness. Such a new era of steel torrent is enough to crush the unknown legion to pieces! Even the Tentacle Type III can't escape such a fate! He thought to himself.

Cao Chuan is taking stock of the chess pieces that Planet 3 has in his hands - 900,000 unmanned unit legions. Qiao Yishan's tactical squadron, which can play a special role, has more than 50 fortresses of all sizes, and with the help of the two planets, he is barely able to support it, and he is on par with the million-scale unknown.

"I don't know how the shipyard is prepared, I don't know when the ship will be built. At that time, Nana and Joan of Arc will be able to participate without scruples. ”

At this time, in the thriving but dead base under Planet 3. There are nearly 100 more people in the shipyard, and they are helpers who have rushed from the New Earth, but their role is not to fight, but to build ships.

Thomas temporarily played the role of chief engineer and compared the drawings of the Elephant-class spacecraft to help the huge spaceship of the Yuanyang-class size be completed as soon as possible.

Underground, at this moment, there are 3 Elephant-class spaceships under construction in a row, and there are mountains of materials piled up around them, occupying at least 10 football fields.

Even in the old shipyard in the base camp, it is necessary to mobilize at least 5,000 skilled workers to complete such a complicated construction work, which is why shipbuilding is called a labor-intensive industry, but here, as an unmanned spacecraft, it has long been completed automatically, but the speed is still a little slow.

This is also a helpless thing, if the construction of unmanned spacecraft is really so fast, so convenient, then simply convert all spacecraft into unmanned spacecraft, human beings are like farming, planting a joint production workshop in spring, and in winter, you can harvest more joint production workshops, unmanned spacecraft, tens of thousands of unmanned units, isn't it wonderful?

The third-generation unmanned unit still has one kind of shortcomings, but as long as there are humans, they can overcome these shortcomings and speed up the manufacturing speed by 1 times, 2 times or even more, so that the Elephant-class spacecraft that originally took two years to build can be completed in half a year.

So the technicians who were originally on the new earth were transferred out, working overtime day and night, just to complete the manufacture of these three elephant-class spaceships in time, and when they were all completed, the East Galaxy Company would have enough mobile force to run around with a total of 800,000 unmanned legions.

And they will be the killer weapon of the balance in a war of attrition.

"Hurry up and help on Boat 2!"

"The bottom cargo compartment needs manpower!"

"Turn the energy-absorbing armor plates around!"

"The assembly of the fusion energy reactor is wrong and it has not passed the test, who is responsible, hurry up, otherwise the construction period will be affected!"

In the ship, from time to time, I heard Thomas's urging and roaring, relying on this dedication, even 24-hour work attitude, everyone was treated as two people, and the construction progress of the Elephant-class spacecraft was very gratifying.

At the end of 2047, a prototype of an Elephant-class spacecraft built in the early years and three newly tested Elephant-class spacecraft will rise into space, quickly breaking through the small number of unknown blockades entrenched in orbital space and heading towards planets 4 and 2.

Half a month later, the four Elephant-class spacecraft returned to the full load of 800,000 unmanned units, instantly increasing the number of unmanned legions on Planet 3 from 850,000 to 1.65 million.

It seems that the situation is about to be reversed. (To be continued.) )
