Tang Zhen's drawings contained a variety of weapons and equipment, and the most powerful weapon was naturally artillery.

This kind of war weapon, which was used on a large scale in the wars of the original world and existed on other planes, was naturally Tang Zhen's first choice.

Although it looks ugly, it is quite powerful, and it is definitely the most suitable weapon to defend Tianxu City.

With the ability of the alarm church, the artillery can be manufactured, but due to the limitation of manufacturing materials, mass production is likely to be impossible.

Just because every artillery needs a lot of metal, but in this low productivity world, metal is often the most precious strategic material.

Even if the situation of Tianxu City is special, a large amount of metal ore has been accumulated during years of excavation, but it still cannot support this consumption.

Sure enough, the problem of manufacturing materials made everyone feel embarrassed.

If it can’t be solved, the cooperative plan will become a joke, and it is impossible to resist the monster’s attack.

"If you try your best to collect, you should be able to make up the materials needed for ten artillery pieces, but if it is used in war, the number of ten artillery pieces will not have much effect at all.

If the number of weapons is insufficient, their deterrence will be greatly reduced, so it is better to melt the metal to make arrows, which may kill more enemies."

After some discussions, the person in charge of the manufacturing base summed up in a serious tone. Judging from his performance, it is clear that he is not optimistic about the plan.

Although shocked by the power of the artillery described by Tang Zhen, the person in charge was very hesitant because it would consume a lot of materials.

If, after doing all you can, the expected results cannot be achieved, it will be a disaster!

The other believers were silent, and they would never express their opinions easily before seeing the power of the weapons on the drawings.

"Your Excellency, what do you think about this? We can make weapons according to the drawings and send people to collect the necessary supplies.

Although the amount of metal required is huge, it should be possible to find a large amount of metal in some ancient ruins.

At that time, you only need to transport the metal back, and you can manufacture weapons in large quantities."

Tang Zhen looked at the bone and asked what was going on.

"There are some ancient ruins near Tianxu City. Some of them belong to mechanical civilization. They are good at making giant mechanical devices, even in the tomb.

According to the information we have, there is a tomb of mechanical civilization nearby, which is connected to the underground passage.

As for the reason for the connection, it is likely that the ancient demon worms strayed into the tomb, which left a secret passage."

Tang Zhen nodded, and then asked the bone: "Since you know the existence of the tomb, why didn't you collect metal materials before, but did you have to wait until now?"

The bone shook his head helplessly, saying that the mausoleum was full of crises. The Wake-up Church had sent people to explore it several times, but each time it had suffered heavy casualties.

Considering that the contribution and the gain are not proportional, the alarm church has no choice but to give up the exploration operation, and at the same time block the passage to ensure that no one else will discover it.

"What caused your heavy casualties? Is it a mechanism in the tomb, or something like a monster?"

Tang Zhen was suddenly interested in the tomb of mechanical civilization. If there were monsters there, it could be regarded as the best place to upgrade.

"There are mechanical puppets, they are the guards of the tomb, and there are all kinds of monsters, one by one is extremely cruel.

In addition to this, there are ghosts and evil spirits, which are the most terrifying things that can kill people silently."

When Nagu said this, there was a hint of fear on his face. Perhaps he had also participated in the exploration back then, but he was almost alive.

After listening to the introduction of the bone, Tang Zhen had already taken his attention, and had to go to the mausoleum.

"If possible, please send someone to clear the passage. After the matter here is over, I will visit the tomb myself."

"Well, if you insist, I can send someone to clear the passage."

The bone was not overly discouraged, and if Tang Zhen could complete the cleaning, it would also be a good thing for the alarm church.

At the same time, you can also observe Tang Zhen and understand his true strength, which is also one of the tasks arranged by Lite.

"Okay, I invite you all to actively cooperate and produce samples as soon as possible.

This matter is related to the survival of the entire world, we must ensure success, otherwise what awaits us is destruction!"

The bone looked very excited, he kept waving his arms and emphasized the importance of this matter.

The believers were also infected, chanting the oath aloud, making the atmosphere of the meeting very serious.

After the meeting, Tang Zhen began to cooperate with the believers to build the weapons and equipment on the drawings.

Because of the existence of monks, many things have become much simpler, such as the production of gun barrels and the moulding of certain parts, all of which can be done with the assistance of monks.

Tang Zhen was eager to let these indigenous people see the power of weapons, so he participated in the whole process. In less than half an hour, a rifle appeared in front of everyone.

This rifle should actually be called a sub-cannon. The bullet is made separately with runes inscribed on it, and it is manually locked after being inserted into the barrel.

After pulling the trigger, the rune array was activated, and the bullet's warhead was pushed out of the barrel and shot towards the target.

Then you can take out the empty cartridge case, load a new bullet, and continue to repeat the shooting action.

The cartridge case cannot be littered, because it can be reloaded, and it does not require too complicated procedures, and each soldier can complete it independently.

"Your Excellency Tang Zhen, is this the gun you are talking about?"

A group of believers from the Wake Bell Church surrounded Tang Zhen, with curiosity on their faces. They really didn't understand the use of this black iron pipe?

In fact, in their opinion, firearms are far less convenient than bows. For a qualified archer, they can shoot many arrows in a short period of time.

In comparison between the two, the musket, which has a complicated manufacturing process and a slower loading speed, does not actually have much advantage.

Tang Zhen naturally saw through the beliefs of the believers, but didn't explain much, just let them see the effect of the actual operation.

Soon someone prepared the target, covered it with a thick animal skin on the sack, and placed it against the wall.

Seeing that the experiment was about to be carried out, a large group of believers gathered around, and they also wanted to see how powerful the weapons made by Tang Zhen were.

Just looking at their expressions, it is clear that they are not optimistic about the power of the firearms, thinking that this is just a modified version of the strange crossbow arrow.

Although it looks much lighter, but the power should be the same.

In their whispered discussions, Tang Zhen suddenly raised the rifle in his hand, and then completed the actions of locking the chamber and aiming and firing at a dazzling speed.

"boom!"

A muffled noise made a big jump for the believers around, and some even screamed.

The scene was very chaotic. Some people even took out their weapons subconsciously and looked at Tang Zhen angrily.

They had never expected that this pipe would make such a loud noise, almost like thunder.

Is such a loud noise to frighten and deter the enemy?

If this is the case, it should be considered very successful, because they have indeed been scared.

Just as the audience marveled at the loud gunfire, someone noticed that the experimental target had been shot through a hole.

"Being able to punch through animal skins proves that the power is not bad, and it should have some effect on monsters."

The bone nodded. He was also taken aback by the gunshots before, but now that he saw the shooting effect again, he felt that this gun was still worthwhile.

But if this is the case, then this kind of firearms can only be said to be dispensable, after all, ordinary bows and arrows can also do this.

It was just that when the inspector walked forward and took off the animal skins, they stayed where they were.

Because he found that not only the animal skin was penetrated, but also the sacks behind it was also penetrated, and then deep bullet marks were left on the stone wall!
