attack city

Nearly three hours later, we finally saw a mountain in front of us. A river passed through the foot of the mountain, and there were many cities parked near the river.

This is the Xishan Trading Ground. I have been to many cities here, but it is difficult to see too many familiar faces.

But today it seems a little different.

"This is Anping City, sending greetings to Shenlong City." A town-level city greeted Shenlong City.

"This is Shenlong City, hello everyone, have a nice trip."

Xiang Yang naturally recognized the other party. He was based in the Crocodile Valley Trading Ground and often sold high-quality steel in that city. Xiang Yang was also their regular customer and bought a lot of steel.

When the other party expresses goodwill, Xiang Yang must also express his own goodwill.

After both parties said hello, they each did their own thing.

Anping City was leaving. When they saw the scale of Shenlong City at Crocodile Valley, they were surprised. It was rare to see such a fast upgrade.

Because they often do business, they are still familiar with the scale of Shenlong City, so they also pay special attention to Shenlong City.

Shenlongcheng entered the river to replenish fresh water.

We set out the next morning and headed to the mining area. The Xishan Mine is very large. The exact location of mining depends on our own experience. Almost no city is willing to sell this information.

If there are good mines, naturally I want them myself and I won’t share them with others.

Newly arrived cities usually have to spend a long time looking for mines. Xiang Yang had been there several times in his previous life and knew a few better locations.

So they don't have to look for it, they just go to the best place they know.

Passing through a corridor dug out of the mountain, they turned into a valley, and then another tunnel dug out.

If you look at it from the air, you will find that this mountain range is also riddled with holes, because countless corridors have been dug out inside the entire mountain range, as if a plow was plowing back and forth in an irregular manner.

After a day of twists and turns inside the mountains, we arrived at a valley.

But inside the valley, the cliffs have been completely broken by explosions. Near the rock wall, there are pits more than two thousand meters away. The deepest place reaches dozens of meters. Standing on the edge of the pit is like standing on the top of the mountain.

Above.

A large section of one side of the pit was bombed into flat ground, extending across the valley and ending in a cliff, looking like a huge ditch.

Because the terrain of this valley is relatively high, all the accumulated water flows out of the ditch and reaches the cliff at the end. On rainy days, it directly becomes a waterfall and releases the water.

The pit is still very dry, with only a small amount of water accumulating.

This is the mine, and Xiang Yang and the others mine directly near the pit.

Generally speaking, cities will not dig underground mines. There is no such thing as digging a mine and entering into mining.

Even if an underground mine can be dug that the city can enter, it is too risky for a city. It is even more undesirable to dig ordinary mines and send people down to dig for good luck, because it is impossible to build mining facilities.

Unless a city completely controls a mineral vein and generates sustainable long-term benefits, then they can build underground mine facilities and send people to slowly dig down and transport it up.

This will cause less damage to the surrounding mountains, and the ore utilization rate will be higher, and some ore veins buried deep underground can also be mined.

As for efficiency, it depends on the situation.

As for safety, the deeper the mineral vein, the worse the safety usually, because there are usually underground energy monsters underground, and the danger for people below is quite high, and underground pits are often destroyed.

This area has also been discovered by other people, but the number is not large. It is impossible for a city to stay in one place for mining all the time, so most of the time there are no other cities here.

"Wu Zhongjun, you lead the team and pay attention to the tremors on the ground nearby. There seems to be a small underground energy giant here." Xiang Yang ordered.

"clear."

Wu Zhongjun led ten soldiers, divided into two teams, and scattered around the mine. A few people occupied the commanding heights to guard, and then he commanded a dozen other people to drive out with equipment and vehicles.

A team of ten warriors is in charge of digging mines and planting explosives, and others are in charge of vigilance, etc., while others are in charge of mining and driving.

Most of these miners are workers from the blast furnace. They are more experienced, and some of them are transferred from farms and workshops.

Overall, it's a hard job without much technical content.

The technical stuff was handed over to Li Sichen and two other technicians. They also went out together to identify the quality of the ore, the specific direction in which to dig it, and the type of metal contained in it.

If it is necessary to use urban combat weapons to destroy rock walls and ground, Xiang Yang and others will be responsible.

They smelted while digging, but the smelting speed was far slower than the mining. After five consecutive days of digging, the ore warehouse in Shenlong City was filled to the brim, and then they returned to the trading site to rest.

Li Sichen and the others started working overnight and worked overtime to melt the ore and smelt it.

The mines here are mainly copper mines, and the iron mines are in the northwest of the Xishan Mine. They need to go around in a big circle, or through the entire mountain. There are corridors dug out by the city, so both sides can be connected.

But the time it takes is about the same as circling outside, because the speed cannot be increased in the mountains, the terrain is not good, and energy consumption may not be saved.

There is also a temporary trading place called Xishan Trading Place there.

In order to obtain higher-grade bronze, further smelting is required. For the time being, they process the ore to obtain primary copper, which they will have to process again later.

Three days later, they set off again, still going to the original place, but halfway through a mountain pass, Xiang Yang saw a city stopped there in front of him and extended an invitation to them.

"We are Shahe City. We are in the passage to your left. Please answer the question from the city that just came in front. We have some things to discuss with you."

Shahe City is also the resident city of Crocodile Valley Trading Ground. When Xiang Yang and others entered Crocodile Valley for the first time, they cooperated with each other and made two sales after that.

"This is Shenlong City, what's going on?" Xiang Yang slowed down the speed of Shenlong City.

"Dragon City! So it's you." Shahe City still remembers Shenlong City, because the upgrade speed was too fast, and the cities that have some contact with them have a deep impression on them.

"We found an extremely high-quality mine, but there are several energy behemoths entrenched there. We can't handle it, so we want to cooperate with you."

Shahecheng said: "It covers a large area over there, and it's no problem for five or six cities to excavate at the same time."

"How high quality is it?" Xiang Yang asked.

"Have you seen the mine closest to the trading site? It's the open-pit mine outside the mountains of the Xishan Mine."

Shahecheng said: "It is two hundred times as pure as that mine, and it is semi-open-air. The stratum where the veins are located is very shallow. If the ground is slightly exploded, it will be high-quality ore."

It is very important that the stratum where the ore vein is located is very shallow. After all, it is difficult to get it if it is too deep. No matter how high-quality the ore is, sometimes it will be in vain.

If it reaches two hundred times the purity of the most common mine outside, it is about fifteen times that of the mine Xiang Yang and the others dug before.

It means that you can extract as much metal from ore that you mine for fifteen days as you can extract from someone else's ore that you mine for one day.

This is a great thing.

"Is it discovered by other cities over there?" Xiang Yang asked.

"Yes, when we found it, a big hole had been dug, which saved a lot of survey time and explosives."

The mines are also covered with useless stones and low-quality ores, which are also disguised. Usually when such high-quality mines are discovered, most of them don't want to be discovered by other cities.

At least it will try to delay the time it is discovered by other cities.

Sharing it with others is impossible.

Therefore, the Lord of Shahe City also knew that Xiang Yang was a bit cautious. If he asked a few questions, he would know if he had lied or if he wanted to trick Shenlong City.

Since they really want to find someone to cooperate with, they naturally answer truthfully.

"Where is the energy giant? Its specific strength level." Xiang Yang asked again.

"Five, two at the town level, one at the village level, and two at the manor level." Shahe City said: "The terrain over there is good. It is a small basin with only one entrance and exit."

"If we work together, we can block the entrance and exit, and we won't be attacked from both sides. We should be able to handle it."

The back side of the city is the weakest part. If it is besieged and attacked from the front and back, it is easy to lose, especially in mountains with complex terrain and many passages.

Even though cities on land can float in the low sky, when approached by a giant beast of the same level, you are likely to be caught or bitten and pulled down before you even get into the air.

It takes time for the chassis to deform. After the city rises, it will be difficult to control the balance, which will be very miserable.

"Let's go take a look first."

Xiang Yang is still very interested. It can save a lot of time. After all, it is fifteen times more pure and fifteen times more time-saving.

In the control room, everyone else agreed to take a look first before talking.

"I'm leading the way. It's still far away from here. Originally, we planned to go to the trading center to find other cities. It's lucky to meet you here."

Shahe City began to turn around, and by the time Shenlong City passed by, the U-turn had been completed.

Then, Shenlong City followed Shahe City and walked for another half a day before reaching the mine that the Shahe City Lord mentioned.

It was exactly as he described. Because the last passage was straight, two of the energy behemoths inside were discovered from a long distance away, while the other three were blocked by the rock wall.

Before, Shahe City did not hesitate to flee backwards and then sent people over to investigate.

Now they not only kept going, they also sped up.

Because there is also a horizontal corridor in front, and the cliffs on both sides of the corridor have been blasted away, and are only about 40 meters high.

They were also afraid that the energy giants would rush out and climb up the cliffs on both sides, which would ruin their plan to block the entrances and exits, and they might be outflanked.

Five energy behemoths were feasting inside. They discovered it only two kilometers away from the two cities. They immediately put down the ore and turned around to look over.

Then, the two town leaders immediately stood up.

This is a breed that can temporarily stand upright on its feet and partially release its hands.

But it was already too late. Shenlong City and Shahe City were moving very fast, almost parallel to each other, and they reached the entrance and exit in no time.

Although the corridor is narrow, if the two cities move forward side by side, there is no problem if they are careful and they will not collide. If they stagger one city in front and back, it will be perfectly fine.

Before it was stable, the two cities opened fire almost at the same time.

Rumbling, all of them were submunition bombs, roaring in the mine. The two manor-level energy behemoths immediately lost their combat effectiveness and lay on the ground. The village-level one was also scarred.

The two town-level ones were only affected by the artillery fire of the sub-munition projectile and were not seriously injured, but now there are only three left, one of which was seriously injured.

"Give us the village level, and you hold off the two town levels." Xiang Yang said, already firing.

Because the village level had just been injured and hadn't recovered yet, there was no way to dodge it and hit the vital point directly, but he wasn't dead yet.

Shenlong City continued the bombardment. At such a close distance, it was attacked continuously as if it were a direct target. The villager finally couldn't hold on anymore and fell down with a bang.

"Ouch!" The two town leaders roared and rushed towards Shenlong City almost at the same time.

But it played right into Xiang Yang's plan. Shahe City's two city cannons specifically bombarded one. When it was still two hundred meters away, the town-level cannon was hit in the head and fell to the ground.

The remaining one was already close, but it was already too late. Under the close combat and continuous artillery strikes from the two cities, it was quickly defeated.

In this way, the two cities occupy favorable terrain together and launch attacks first, so the efficiency is still very high.

As long as there are no mistakes, it is almost accurate every time.

"Let's go to the right, you go to the left." The Lord of Shahe City was in a good mood. This was their second time here. Although there was an extra Shenlong City now, there was no need to come in vain.

Anyway, this mine is very big, and it would be no problem to have a few more cities dig it.

If energy behemoths often appear, they can come together in the future. It will be safer. They often move in the same trading place, and they will encounter them frequently. It is easy to get together.

Eating alone requires strength. When the city is small, it is very simple to consider the problem, because they cannot handle it themselves, and safety comes first.

"No problem, let's dispose of the body of the energy beast first."

Xiang Yang said: "Each person has one town level, two manor level and one village level. Let's choose one from each."

"Okay, as you said, whoever kills at the town level will get it, manor level or village level, you choose first." Compared to the mineral veins, this is not much, the Lord of Shahe City said indifferently.

Of course it doesn't matter to Xiang Yang, this is really just an embarrassment.

Once the blood recovery of the energy giant was completed, they began to mine separately.

Just like what was said in Shahe City, the surface here is full of high-quality minerals. Just bury some explosives and the rubble will be enough to pick up.

Moreover, not only is the quality of the ore here high, but it is also easier to obtain the ore.

It might take four hours to get a cart of ore at the original place, but it only takes three hours here.

The reason is that the mines there are deeper and the rocks inside are harder and more precise, while here they are more scattered and have many rock crevices. Whether it is explosives or using City Fury and a gravel crusher, it will be easier to break them.

So the efficiency is basically close to twenty times.

Xiang Yang also felt that he had gotten a bit of a bargain. Fortunately, there were energy monsters here, otherwise it wouldn't have been their turn.

At noon the next day, Shenlong City was still digging for ore, and a report from Wu Zhongjun came over the internal communication channel:

"We found a county-level city in the passage ahead, coming this way. Their destination seems to be this way."
