Doomsday: Unlimited Upgrade Mobile City

Standing in the fighter jet factory, Wang Cheng picked up the walkie-talkie: "Su Mei, have the 20 tons of ore I asked you to buy arrived?"

A gentle female voice came from the walkie-talkie: "Report to the city lord, 20 tons of ore has been delivered to the factory gate by a transport truck."

"Okay, let him drive in."

The minecart drove into the factory and threw 20 tons of unrefined ore and sand into the boiler.

A plane appeared on the screen in front of Wang Cheng.

【Falcon 1 Type】

[Single machine weighs 9 tons,]

[Using suspension take-off and landing, no flight deck is required. 】

[Captain: 14.57 meters]

[Wingspan: 8.78 meters]

[Maximum take-off weight: 19277 kg]

[Can be mounted: air-to-air missiles, air-to-surface missiles. 】

"When 20 tons of ore go down, will a plane be randomly generated? But it should be related to the quality of the ore."

This is the only military aircraft that Wang Cheng can currently produce indefinitely.

The ore you put in is different, and the fighters produced are also different.

But he is now in Fu Province, where the Shan Duo mines in Fu Province are rich.

The ore put in is separated and refined, and it is refined by machines into materials required for various aircrafts such as aluminum alloys.

Sand is refined into glass, and the entire factory is fully automated.

In addition, some explosive components in the ore are separated to make the explosives department of the missile.

The ore is thrown in, and 20 planes can be produced in 10 hours!

The premise is that Wang Cheng has to put in enough ore. If it is to produce one by one, it will be very slow.

At the same time to produce 20, put 400 tons of ore into it.

To put it bluntly, it takes 10 hours to build one plane, and 10 hours to build 20 planes, and it will be more efficient to start at the same time.

The rest of the waste is rocks, which are discharged to the garbage area.

"Su Mei, release the news, no matter what kind of ore I want! 100 kilograms of sea salt, 20 tons of ore!"

Exchange sea salt for ore.

As soon as the news came out, Nanfu City, Black Dragon City, Cyanwood City, and various cities were all eager to exchange.

Dude, 100kg of sea salt for 20 tons of ore?

Although 20 tons of ore contains a lot of minerals, but!

Ore is not refined.

If you throw this kind of ore on the road, it is estimated that it is a stone on the side of the road, and no one will pay attention.

Lao Su scratched his ears: "20 tons of raw ore, unrefined ore, exchange for 100 kilograms of sea salt?"

"Yes, Dad, you heard it right! Su Mei told me, and I tasted a handful of that sea salt, it's a top-quality product!"

Premium sea salt?

The old man shouted excitedly: "Hurry up! Let the warehouse take out all the remaining ore! Send Qizhen to go to the mining mountain quickly! How much can be exchanged! This Spring Festival market is over, but it will not be exchanged."

Various cities swarmed, and trucks after trucks of ore were sent to Donglong City.

They also carried away the sea salt of Baihuahua.

For them, it's blood money.

Burning salt to make salt takes too much time and space, and they have nowhere to make it on a large scale.

And for Wang Cheng, he doesn't have anyone to mine, but sea salt is easy!

Just sit Donglong City on the seashore and pump a few pipes of seawater to make sea salt.

In these few days, Wang Cheng is always welcome! How much is collected, almost fills the entire warehouse.

Under the East Long City, a large amount of stone waste has been accumulated.

From time to time, a large amount of stone dregs are dumped, which are all wastes left from mining.

And in Dongshan Mobile City of Donghuang Group.

Zuo Da, the dwarf city master, and Zhao Gao are discussing.

"How much food did you get at the Spring Festival market?"

Zhao Gao smiled proudly: "I sold arms for grain in several warehouses, and I sold some old weapons that were eliminated to small cities. It's really profitable."

Zuo Da picked up the teacup and took a breath and drank it unhurriedly.

The dwarf city lord Zuo Da said: "Have you noticed that Wang Cheng has been buying a lot of ore in recent days. Is he planning to expand the city?"

"I heard that he exchanged sea salt for ore. This kid must have mastered advanced salt-making technology."

The four city lords in the conference room looked at each other with greedy expressions.

"This Donglong City is a big fat fish, and he can't be let go."

"Energy shields, tachyon cannons, advanced mechas, Wang Cheng can't be let go!"

Zhao Gao clenched his fists: "Yes, you can't let him go! Once this kid leaves, he may call his accomplices to attack us. We might as well strike first and kill Donglong City!"

Zuo Da, the dwarf city lord, slowly put down the tea cup: "Today is the last day of the Spring Festival market, and it will end at dawn tomorrow. According to the trading rules, no attack is allowed for 24 hours. But!"

A gloomy smile appeared on Zuo Da's face: "We can block the road! Our four big cities can block the main roads so that Donglong City cannot leave."

Blocked?

Everyone's eyes lit up.

Fu Province is full of mountain roads, and there are only a few roads that can go out.

The big city of 10,000 meters blocks the road, and no one can get out!

Another city lord, Scarface Zhao San stood up: "But if we block the road and trap everyone in Xia City, will it cause misunderstanding among the small city lords? They are besieging us in hundreds of cities."

Zuo Da said, "Don't attack other city lords, tell them our target is Wang Cheng, and they won't provoke us."

"Yeah! That's it!" Zhao Gao slapped his thigh excitedly.

Four big cities block the intersection, and Wang Cheng's great ability can't escape!

It's time for them to reunite! Surrounding Donglong City from all directions!

Zuo Da, the dwarf city lord, stood up: "Let's act now, let's block the mountain pass in four directions!"

"Dele!"

Dongshan City, Dongmen City, Dongwu City, and Dongdao City, four major cities left the Spring Festival Market.

In the main building of Donglongcheng, Wang Cheng put down the telescope.

"They're in action, and the security system sent a reconnaissance plane to see it!"*
