Just do it, anyway, Noah City is buying zombies every day.

Although the introduction of a series of new regulations and changes in the purchase price caused a significant drop in the number of zombies, there was a rebound after a short time.

There are many reasons for this!

First of all, the influence of Noah City is radial from the inside to the outside. The zombies in the central plains urban agglomeration are not caught much, but there are still a large number of zombies in the four fortress urban agglomerations.

Anyway, it is necessary to clean up the zombies. Compared to killing the zombies, it is better to catch alive and exchange money.

The transportation distance is too long and the cost is too high?

It's ok! The Zombie Acquisition Department cooperated with the Ministry of Railways to provide people with door-to-door acquisition services.

People catch zombies locally, and as long as they send them to the local train station, the staff will buy them on the spot, directly bearing the cost of long-distance transportation for people.

After the zombies are full, the train will drive directly to the top of the zombies transportation pool in Noah City.

At this time, the steel fence on the roof will automatically retract, and at the same time, steel claws will extend under the rails to lock the wheels on the rails. Then this section of the rail will rotate 180 degrees with the length of the train as the central axis.

Because the front and the carriage are connected by a rotating shaft, the rotating front of the rear carriage will not be affected.

And all the zombies in the carriage will naturally fall into the zombie transportation pool.

The track resumes and the train leaves. The whole process takes only fifteen seconds.

Efficient and safe.

And as the Qin State railway system continues to radiate to the periphery, the coverage area is getting larger and larger.

Not only did the zombie purchases not decrease under the influence of price, but they kept breaking new records.

Especially the number of senior zombies has increased the most!

Although Qin Hao reduced the purchase price of ordinary zombies and mutant zombies, he also increased the purchase price of lickers and tyrants.

In the face of huge profits, many professional corpse hunting teams are more inclined to challenge advanced zombies.

We must know that Qin Hao has already regarded **** grass, southern barbarian vine armor, poisonous thorn spear, deer living grass, poison ivy, and other farm plants as commodities for full-scale sales, which can make money and quickly improve the combat power of the whole people. Kill two birds with one stone.

Those professional corpse hunting teams, after earning money, will spend money to improve their strength, then challenge higher-level zombies, and then spend money to improve their strength, thus forming a virtuous circle.

Qin Hao was affected by the last time ordinary people were converted into zombies for sale, and he did not dare to sell the parasitic vines.

Although parasitic moss can only control zombies, in order to obtain stronger zombies, some people will use zombie poison to infect mutants to become zombies.

Now, the number of zombies accounted for by Qin Hao's zombie enclosure can easily exceed one million every day.

If you convert the number of high-level zombies, this number can be doubled.

Although the plantain fan is a big killer, it is of little strategic significance, so naturally it is not too anxious to ripen, and Qin Hao is worried that the blood demons will come at any time.

Time waits for no one, Qin Hao can only focus on defense.

Qin Hao directly used batch planting to start large-scale planting, pea shooter, watermelon throwing machine, corn cannon, and improved super zombie creeper.

After these plants are planted, Qin Hao will directly send them back to Noah City through the item sharing warehouse.

And then sent to various borders by the railway of Noah City.

If you look down from a high altitude, you will see that the border of the human activity area of ​​Donghua Island is rapidly turning green.

A green Great Wall of more than 10,000 kilometers is rapidly taking shape.

The Qin army stationed on the border looked at the green Great Wall that spread to the end of his line of sight, and was extremely surprised.

"This is really magnificent!"

"What kind of courage is this to give birth to such an idea and put it into action!"

"Strong my Qin country, strong my King Qin, strong my Qin army!"

"Long live King Qin!"

"King Qin mighty!"

This long green wall is only half of the entire border defense project.

Because Qin has unified the world and is destroying zombies on a large scale, the steel walls of major cities have lost their meaning.

These steels returned to the steel mills, were converted into weapons and cannons, and sent to the border.

The energy cannons originally scattered in various cities were naturally concentrated on the border.

A large part of the reason for this is to ease the pressure on resources in human activities.

Although Qin State unified this place, the resources here are not rich. Although there are various mineral veins, both the quality and the mineral reserves are not ideal.

Especially precious metal veins, even fewer.

The application of precious metals in the industrial field has an unshakable position.

Take gold as an example. Gold has very good chemical stability, coupled with excellent ductility, thermal conductivity, and electrical conductivity.

It is destined to have an irreplaceable role in the electronics industry and high-precision technology.

Important circuit interfaces, connectors, high-current wires, transistor components, temperature measurement materials in the instrument industry, excellent reflectors for electromagnetic radiation, anti-corrosion coatings, etc. all require gold.

As the most conductive silver and copper, let alone.

These metals are also indispensable materials for the manufacture of energy guns, rocket launchers, tanks, and aircraft.

In order to solve the problem of insufficient precious metals, Qin Hao not only contributed all the gold and silver jewelry he took out from the Shocking Treasure.

Qin Hao also ordered the Ministry of Economy of the State of Qin, together with the Central Bank, to introduce paper currency to replace the gold, silver and copper currency circulating in the market to ease the pressure of insufficient precious metals.

To put it bluntly, paper money is a kind of credit currency, as long as it is bound to the rough energy stone, plus Qin's credit guarantee.

It is not difficult to promote paper money.

There were mutant sunflowers outside and zombies in the system, and Qin Hao was almost dizzy.

But soon, Qin Hao received the news from Tangtang that the detection radar and space radar had been initially successfully developed and immediately entered the actual application test.

Qin Hao left the mad iron, the excavator, and the vine armor army to continue planting Dave's mutant sunflower.

He hurried back with the three little guys. He couldn't wait any longer. There was always a nuclear bomb hanging on his head. It was really uncomfortable!

Different from Qin's wasteful waiting, full of passionate people everywhere, the Gorefiends of the Gorefiend City looked terrified and frightened, as if something extraordinary had happened.

"Have you heard that five Saboras have been attacked, and all of them have become monsters."

"Oh! Such a big thing has happened, I am afraid that the entire East China Continent will know it!"

"Who would have thought that the pinnacle weapon of human technology could not kill those monsters. It was really terrifying!"

"Unfortunately at this time, a rebellion broke out in the human breeding area. The price of blood food changes every day. If this continues, we will all be hungry!"

"I believe that there will be a solution to the Great Duke of Blood Soul."

"hope so!"
