After hearing Guo Yun's words, Tang Zheng was shocked.

The arsenal drawing is completed!

This can reduce bullet costs.

The high cost of bullets has always been a worry for Tang Zheng, and the soldiers cannot give full play to their full potential in battles.

Although more than a hundred bullets are fired every day, it is definitely enough under normal circumstances, even when fighting people, but it is not enough to fight zombies.

There are too many zombies in this world, often numbering in the hundreds of thousands or millions, and no amount of bullets is too many.

So after hearing Guo Yun's words, Tang Zheng didn't even have time to rush to see the corpses in Fengcheng, so he took a plane back to Zhuguang City.

When he returned to the city, it was already a brightly lit night. Tang Zheng landed directly in the inner city, where Guo Yun was already waiting.

Seeing Tang Zheng arrive, he immediately handed over a drawing as if it were a treasure.

"General, this is the blueprint of the arsenal. After you use it, the building options of the arsenal will be added to the system."

Tang Zheng didn't say much and immediately used the blueprint.

Sure enough, on the system's building page, there is an option for an arsenal.

[Arms Factory: The factory has three bullet production lines, which produce general-purpose bullets for pistols, general-purpose bullets for rifles and light machine guns, and general-purpose bullets for heavy machine guns and sniper rifles. It has artillery shell production lines, rocket launcher production lines, and landmine production lines.]

[When producing bullets, copper supply can reduce capital costs by 60%, and gunpowder supply can reduce production costs by 30%.]

[The arsenal has one hundred technical personnel, which does not occupy the army quota, but needs to provide food and logistics support. The price is 50,000 gold.]

After seeing the introduction about the arsenal, Tang Zheng let out a long breath.

Finally, it is possible to solve the problem of bullet cost.

Now Tang Zheng's pistol bullets cost 0.1 gold per shot, and rifle and light machine gun bullets cost 0.2 gold per shot.

A 12.7mm bullet costs 0.4 gold per round.

This is also the reason why Tang Zheng's battles are too expensive. A machine gun fire is worth ten thousand taels of gold.

If enough copper and gunpowder are provided according to the conditions of the system, the cost of bullet production will be directly reduced by 90%.

Even if the purchase of gunpowder itself costs some money, it will reduce the cost by at least 85%.

In this way, the combat effectiveness of Tang Zheng's troops was greatly improved.

Today's battle can be fought almost from morning to night, and the number of zombies annihilated is definitely more than 80,000.

It's possible to pay 200,000 yuan, and the Peace Bridge can be penetrated in two days.

So even though Tang Zheng currently only had 80,000 gold, he did not hesitate to spend 50,000 to buy the arsenal.

An important military site like an arsenal should naturally be built in the inner city.

Tang Zheng has also planned the inner city area a long time ago. Although he only has his own official residence and wind power plant here, the basic roads and facilities have been completed.

Arriving at the address he had chosen long ago, Tang Zheng built an arsenal.

After the placement was completed, a factory area appeared.

There are a hundred staff here, so there is no need for Tang Zheng to send people into production.

The production lines, work workshops, storage warehouses, etc. are all here, the personnel are in place, and the electricity is connected, but there is no production because raw materials are needed.

Tang Zheng opened the system again and looked at the resources page.

Although copper was not a priority purchase before, it is still an important material. Anyone brought back by a survivor or adventurer team will be accepted by Light Chaser City.

Therefore, Tang Zheng currently has more than 60 tons of copper as a material.

"First put these more than 60 tons to use, and then issue a copper acquisition task on the trading floor."

"Okay General, we are already doing this. Some adventurer teams have already left the city to find copper. We estimate that we will be able to bring some back within a day or two."

"Well, with copper, the cost of bullets has been reduced by 60%, and then only gunpowder is needed."

Tang Zheng purchased another ten thousand gold worth of gunpowder from the system and gave it to the person in charge of the arsenal.

With the raw materials in hand, the arsenal started working overtime overnight.

Tang Zheng watched this process for a while.

The workers were very efficient. Two hours later, the first batch of 20 boxes of 1,000 rounds of heavy machine gun bullets had been produced.

"General, this bullet can be sent to the resource recycling station for storage, or it can be stored in reality. You can take it out at any time if it is in the resource recycling station. In reality, soldiers must carry it."

Tang Zheng nodded: "Then put these in the recycling bin first, and just take them out when I need them."

"Okay General."

A truck came over and started loading bullets.

It was already late at night, and Tang Zheng couldn't rest yet. He let the plane take off again, taking advantage of the darkness, and headed straight for Fengcheng.

By the time we arrived near Fengcheng, it was already dawn.

In the dawn light, Tang Zheng finally found the group of corpses.

The group of corpses seems to have grown a little bigger. The exact number is somewhat impossible to count, but it is definitely more than before.

Moreover, the corpse group has now left Fengcheng for more than 100 kilometers and is heading north.

Looking down vaguely from the plane, Tang Zheng discovered the specific changes in the group of corpses.

That is, the number of mutant zombies in this group has greatly increased.

Although this zombie group was large before, the number of mutated zombies was only between 1% and 2%.

But things are different now. Looking down from a high place, mutated zombies can be seen almost everywhere.

Among the densely packed corpses, there are often some large armored zombies and very fast and agile zombies walking among them. Many of the mutant zombies have even evolved to a certain extent, showing signs of evolving to second-level mutations.

Among the entire zombie group, the proportion of mutated zombies exceeds 5%!

This is a very scary number. If there are one million zombies in this corpse group, the number of mutated zombies will exceed 50,000.

What's more, there are many near-mutated zombies inside. As the battle progresses, many of these things will definitely evolve again.

Moreover, Tang Zheng was still in the team and found a few orangutan zombies and lickers here and there.

Although the number of these two kinds of zombies is very small, the fact that they can be found in such a huge group of corpses proves that these two kinds of zombies are definitely not as simple as one or two.

As for the Corpse King, Tang Zheng has never discovered it. This thing is hidden very deep and is completely impossible to find.

After watching for a while, Tang Zheng ordered to return.

There won't be any surprises this time. The corpses are heading towards Light Chaser City, and they probably won't stop on the way.

This means that in five days, this terrifying group of corpses will arrive at Chasing Light City.

Before this group of corpses arrived, Tang Zheng still had a lot of things to do.

First of all, he must capture Shuanglin County as soon as possible and obtain funds from the gold store to prepare for war.

In addition, he needs to settle matters on the alliance's side. After all, the alliance still occupies the south gate of Chasing Light City.

He didn't want to think about the situation on the alliance side for the time being. First, he had to capture Shuanglin County.

Tang Zheng, who left Fengcheng and barely slept a wink all night, returned to the front line again.

Even if he took a plane, it would be the morning of the next day when he arrived in Shuanglin County again.

After a brief rest, the battle will continue the next day.

The battle this time was even more intense compared to the first day.

Because the Light Chasing Army has an arsenal here, the arsenal worked overtime last night and produced a large amount of ammunition.

This immediately relieved Tang Zheng's financial pressure. Since he had raw materials, Tang Zheng basically didn't spend a penny today and achieved better results than yesterday.

With sufficient ammunition, most of the soldiers have been upgraded to three stars. Today, from early morning to dusk, the battle lasted for twelve hours!

Compared to yesterday's record of annihilating 80,000 zombies, today they annihilated 180,000 in one fell swoop!

At the end of the battle, the corpses of zombies almost blocked the river under the bridge, which forced Tang Zheng to end the battle and send flamethrower warriors to start burning a large number of zombie corpses.

Thick black smoke burned for almost the whole night. Later, Tang Zheng simply asked someone to pour gasoline on the body.

After a lot of trouble, the river finally resumed its flow.

This was the most strenuous day, but the results achieved were also significant. The number of corpses on the other side of the river had been significantly reduced.

Almost all the zombies in the area near the new city were attracted, and the remaining zombies were located further away.

The battle on the third day was much easier than the first and second days.

The soldiers took turns to fight and fought all morning. At noon, the ammunition was refreshed. Tang Zheng stopped the cannon bombardment and began to use guns to fire bursts.

The sporadic zombies died one by one under the shooting of the soldiers, and the riverside gradually became quiet.

When the last zombie was eliminated by a sniper, the battle in Shuanglin County that lasted for half a month finally came to an end.

The cement floor here has turned dark brown, and the dirty blood has seeped into the ground, and it seems that it will not be able to dissipate for a long time.

The funds here are not easy to collect. I didn't have time to collect them on the second day. I simply collected them on the third day. Almost 300,000 zombies died in total, but only brought more than 20,000 gold to Tang Zheng.
