Time flies.

Half a year has passed in the blink of an eye.

During this time, SH City entered a period of rapid expansion.

The troops led by Lu Quan attacked everywhere to clean up the insects and beasts around SH.

Although from time to time, more than a thousand beasts would attack SH, but the blue earth troops, which had already changed their guns, directly met them head-on, repelling the attacks of these insects and beasts again and again.

And after having enough power to protect himself, Lin Chen began to actively expand.

On the one hand, the engineering construction corps led by Lao Tang worked overtime to expand SH, and at the same time, dozens of small satellite fortresses were developed along SH.

These small satellite fortifications provide logistical support for the ground forces of the land. At the same time, a large number of refugees transferred from other cities will also come to the satellite fortress for resettlement first.

These refugees will live in these satellite forts for a period of time before being assigned to SH City Security Zone after basic screening and training.

This method was later jokingly called the ring by the people living in SH. The central city is the first ring, and then it extends outward to the second, third, and fourth rings!

The closer it is to the central ring area, the more developed the economy and the higher the security. That's why almost everyone wants to head to the Central Ring. And in order to achieve this goal, these new immigrants are working hard, hoping to get enough points to move to the inner ring.

At the same time, relying on this way of hitting and building satellite fortresses, the Blue Earth Organization, in the eastern part of the former China, quickly extended inland.

One of the farthest satellite fortresses is already almost eight hundred kilometers from SH. If it were not for the availability of reliable means of air transport, such distances would not have been able to guarantee the rapid transportation of people and materials.

Today, a group of refugees who fled from southern China are coming to SH on a PS1 transport ship from the original FJ area.

Now almost the entire territory of China, more or less, has heard of this mysterious blue earth coalition government.

The other side has a large population and a strong strength.

What's more, they have a complete industrial manufacturing capacity, which can manufacture and maintain various machinery and equipment, which greatly improves the ability of humans to fight insects and beasts.

At the beginning, when the troops led by Lu Quan went to various cities to look for survivors, no one believed that there was a safe zone for human civilization in SH City.

But when Lu Quan's troops showed advanced weapons and powerful power, these survivors had to believe that there really was a place where the fire of human civilization existed.

Wherever they are now is paradise.

Today, these refugees of about 3,000 people are the first survivors found by a unit under Lu Quan from the FJ region.

Unlike SH, the FJ area is located in a mountainous area, and the consequences are even more tragic after the infestation of insects and beasts.

The density of insects and beasts in the mountains is amazing, perhaps because the insects and beasts are all mutated from local organisms, so the more mountainous and forest areas, the more dense the insects and beasts.

Of course, in those highly polluted areas, insects and beasts will also build nests, and the number is also amazing.

However, in general, the more plain the area, the less severe the insect and animal infestation, and the more mountainous and jungle areas, or highly polluted areas, the more severe the insect and animal infestation.

These 3,000 people are almost the only remaining population of a prefecture-level city.

Originally, this prefecture-level city had a permanent population of 5 million. And after the end of the world, the survival rate is less than 1 in 1,000. One can imagine how tragic the disaster was back then.

And now, they have finally escaped the hellish city and are about to go to the fabled human home.

The PS1 transport ship is very fast, and this is an intraplanetary transport ship that the mechanical technology department led by Bi Yuwei spent a lot of time reversing the Jade Bird.

P stands for plant, which means planet, while s stands for ship, which means ship, and 1 stands for the first type of ship developed by the Ministry of Science and Technology.

Unlike the Jade Bird, the PS1 transport ship cannot rise to high altitudes, and can only rely on ground effects to fly at ultra-low altitudes.

Of course, this is not because Bi Yuwei is unwilling to build a transport ship that can fly at high altitude, but because of the limitations of industrial manufacturing capabilities.

The manufacture of the ion engine, the core component of the transport ship, is still too difficult for the current Biyuwei.

This thing is the highest technology of pre-apocalyptic humanity. Reverse reduction alone will not achieve the same power output at all.

Basically, the particle engine they created only had a thrust output of ten tons at most, and it weighed several times more. Even after Lin Chen's reinforcement and reaching the third level, he could only get a thrust output of up to eighty tons.

And the PS1 type transport ship, the self-weight is more than 500 tons, plus the need to transport personnel and materials, so the maximum weight of the entire transport ship exceeds 1,000 tons.

The thrust decreases, the dead weight increases, but at the same time it has to meet the transportation requirements of large loads, and in addition to flying in the wild, it is necessary to prevent insect and beast attacks, so the entire transport boat is armed, in order to meet all the above requirements, Bi Yuwei and others have to install six ion engines for him. Capable of providing almost four hundred and eighty tons of thrust for the entire transport ship.

But this thrust was clearly not enough to meet the flight requirements of the PS1 transport ship. Therefore, Biyuwei and they can only build the entire PS1 transport ship very large, using the ground effect to provide additional lift to meet the take-off requirements.

Fortunately, the PS1 transport ship is relatively durable, and the ion engine strengthened by Lin Chen is also very strong, even on ordinary dirt roads, it can take off and land smoothly.

However, due to the high cost of enhancement, the entire Blue Earth organization has only ten PS1 transports so far.

The rest are large laden airships.

These airships are built with a low-end technology, as long as they have a small thrust propeller engine and enough volume of airbags, this thing can fly.

And the control is simple, you can park anywhere.

In order to meet the needs of material exchange between the various satellite fortresses and the SH security zone, the Blue Earth government has specially built a large airship factory to build this heavy airship on a large scale for the transportation of materials.

And as the transports got closer and closer to SH, a large number of heavy airships with gray livery began to appear in the sky.

These giant airships, which are one or two hundred meters long, slowly float in mid-air, and at the tail of the airship, several large propellers are spinning at high speed, providing power for the airship to move forward.

And underneath these behemoths hang heavy shipping containers, filled with materials collected from all over the world.

For a while, seeing how many man-made objects appeared in the sky, everyone couldn't help but be surprised.

I saw a timid little girl, hiding in her mother's arms, curiously looking out from the skylight of the transport ship.

When she saw a large number of oval airships in the sky, she curiously stretched out her little head and asked, "Mom, Mom, there are so many round things in the sky!" What is that? ”

The young mother looked at the airship in the sky, and said with relief: "That's an airship, Xinxin, when we came, didn't an uncle explain to me the overview of the City of Hope, there are these big guys who are specifically responsible for transportation, they are airships made by the City of Hope, specially used to transport supplies!" ”

Xinxin: "Wow, they're all so big, the uncles in the City of Hope must be very powerful if they can make something so big." When we get there, we don't have to be afraid of bugs anymore, do we? ”

Mother: "Yes, Shin Shin, where is the city of hope for our human race." Where there is the fire of our human civilization, we will be very safe there, and we will no longer have to be afraid of insects and beasts! ”

Seeing the airships all over the sky, everyone in the transport boat suddenly felt a heavy sense of security.

This is the paradise of mankind, the last fertile land!
