2575 Danger lurking in every corner (1)

The lack of weapon materials was still a headache.

Most of the metal materials in the Heaven’s Wall city’s storage were used to make guns and cannons, and the stock was getting smaller and smaller.

For example, the underground tomb that was previously discovered had basically been emptied out after a period of moving.

The remaining metal materials were all shockingly large, and it was impossible to complete cutting and moving them in a short time.

With no other choice, he could only choose to give up.

The two mountains near the Heaven’s Wall city did have iron ore, but the primitive mining efficiency was too low to meet the needs of weapons.

Perhaps after a while, the metal materials would be completely used up, and the weapons could no longer be produced.

Of course, this matter would be left to Tang Zhen to worry about. With the methods he had, he would be able to find a solution to the problem.

They couldn’t count on Tang Zhen for everything. The residents of the Heaven’s Wall city felt that they should also do their part. After all, they were protecting their homes and couldn’t let the cultivators in the building do all the work.

The enthusiasm of the Heaven’s Wall city was inspired. They worked even harder and tried to solve the problem.

Since he lacked the metal needed to make weapons, he would look for other methods to see if they could replace metal.

The first material that he thought of was naturally the stones that were the most abundant in the Heaven’s Wall city. Moreover, the use of stones as weapons had never stopped since ancient times.

Ordinary stones definitely wouldn’t work, but a special stone similar to Obsidian was developed by the residents of the Heaven’s Wall city.

The most amazing thing about this kind of stone was that after being roasted at high temperature and poured with water, it would explode into a triangular stone strip as thick as a thumb.

Using this characteristic, it made stone mining very simple. All they needed to do was to use fire to heat it up.

After some polishing, it could be made into a perfect arrow that looked similar to the armor-piercing arrow.

After tying the arrow to a wooden stick with a straw rope and then dipping it in glue, a special arrow was made.

It could be placed on a special ballista and shoot dozens of arrows at once to attack groups of monsters.

It could also be fired through a special crossbow, but compared to a mounted crossbow, the lethality was obviously much lower.

This type of arrow could save enough metal materials and could maintain its lethality against monsters. It could even penetrate the scales of monsters.

Due to the lack of materials, the residents of bamboo city tried to use the bones of monsters to make weapons.

A material like bone had long been used by people. It could be said to be the most primitive weapon material.

The bones of these monsters were different. They had properties that other bones could not compare to, and their toughness and hardness were very good.

In the absence of materials, the residents of the Heaven’s Wall city naturally would not waste these bones. The monsters that were killed were once again smashed into pieces.

Bone arrows, javelins, and some other random weapons were continuously created by the skilled residents of the Heaven’s Wall city.

The residents of the Heaven’s Wall city used their own methods to silently provide support, and the cultivators in the tower City were not idle either.

The existence of the runic airships and flying beasts allowed them to think of a way to deal with the monster army. Even if they could not successfully intercept it, they could still cause losses.

In other words, it was an opportunity to increase his level.

These cultivators of loucheng city took the initiative to apply, hoping to obtain a runic airship or a few beheading airships to investigate and harass the enemy.

The number of runic airships in Heaven’s Wall city was limited. One of them had crashed earlier, so the cultivators in Heaven’s Wall city were asking for too much.

Tang Zhen didn’t refuse directly. Instead, he sent out a few runic airships to carry out the investigation and harassment mission against the monster army.

This way, they would be able to buy enough time to complete all the preparations before the monster army arrived.

The new cultivators of loucheng could join the battle, but they didn’t have the right to control it. After all, there were only a few runic airships. Who should they use them for?

If he really wanted a runic airship, he would build it with them and modify and design it according to his own ideas.

Cultivators from different races and territories had their own specialties. If they could be used on the runic airships, it might bring people unexpected surprises.

Just as the entire city was mobilized, an accident suddenly occurred on a mountain peak on the side of the Heaven’s Wall city.

……

In the narrow cave, there were many places that were pitch black. From time to time, he could see specks of fluorescent light, like the eyes of a monster.

Due to some special reasons, there were many residents on the peaks on both sides of the mountain. Their main task was to mine and plant.

At the same time, they were also expanding the space inside the mountain and increasing the living area of the Heaven’s Wall city.

However, due to the dirty and messy environment after mining, there were all kinds of dangers, so it was not suitable for living.

As the monsters attacked tianxu city again and again, wisps of evil aura slowly appeared in the dark mine caves on both sides of the mountains.

The demonic Qi would appear and find suitable targets to infect. The rats, snakes, and insects in the mine would be the first to be attacked.

They were infected by the demonic Qi and turned into strange things, lurking in the darkness.

Because of the environment, no one had discovered these monsters immediately, which gave them enough time to grow.

Unknowingly, more and more monsters appeared, and they became restless.

In the middle of the night, a sneaky figure appeared and was looking for something in the mine.

When the monsters encountered them, they all hid to the side, as if they were very afraid.

He was holding an ancient map in his hand, constantly searching in the mine, and muttering to himself.

“This is the place, why can’t I find it?”

It seemed to be because of anxiousness, the eyes that were emitting a dim light flickered, like a light bulb with an unstable current that could go out at any time.

After growling a few words, the figure closed his mouth, as if he was trying to calm the anger in his heart.

“Something’s wrong. This body’s condition is getting worse and worse. It’s irascible and can’t be suppressed at all.

I don’t have much time left. I have to find the core control room as soon as possible and try to activate the heavenly Divine weapon bi an.”

When the figure said this, a deep hatred flashed in his eyes, almost materializing.

“Tang Zhen, Allie and that bone Kasaya.

Hehehe, just you wait. It won’t be long before I punish you.”

When this figure spoke, he was like a night owl, exuding a sinister aura.

He looked at the map again and walked along the mine for a distance. Suddenly, a strange symbol appeared on the rock wall in front of him.

The figure tilted his head and stared at the symbol. After a while, he let out a sickly laugh.

“So that’s how it is. I was wondering why I couldn’t find the sign at the intersection after searching for so many years.

Even if he had lived for thousands of years, he was still a mortal. How could he see the marks left by cultivators?

How laughable and pathetic!”

After mumbling a few words in a sickly manner, the figure walked to the front of the rock wall and reached out to press on the symbol.

“Ka ka!”

The sound of gears turning could be heard. Then, a black hole appeared in the rock wall, and behind it was a long and narrow passage.

Without any hesitation, the figure entered and the passage slowly closed.

No one noticed that when midnight arrived, the eyes of the Super statue on the mountain to the left of the Heaven’s Wall city seemed to move slightly.
