Nightmare Immortal Era

Chapter 25: Kun - 12 Style Mobile Shooting Infantry Fighting Vehicle

Cultivators in the Physical Body Realm often use close combat weapons such as knives, swords, and spears because their blood and qi can be emitted externally starting from the Fifth Layer of the Physical Body Realm. However, the emission range is limited.

Close combat weapons can benefit from the enhancement of the blood and qi, becoming harder and sharper.

The blood and qi can also attach to the weapons, allowing them to be concentrated without the need for cultivation, maximizing their utilization.

Mortal Weapons are divided into five grades: Ordinary, Low Grade, Middle Grade, High Grade, and Peerless Grade. The classification is based on their ability to bear the blood and qi.

Even if an object cannot bear the blood and qi, it can still be considered a Mortal Weapon. However, because it is forged by superhumans, its quality is excellent and can be passed down as a family heirloom in the mortal world.

A Low Grade Mortal Weapon can bear the blood and qi of a cultivator up to the Sixth Layer.

A Middle Grade Mortal Weapon can bear the blood and qi of a cultivator up to the Eighth Layer.

A High Grade Mortal Weapon can bear the blood and qi of a cultivator up to the Tenth Layer.

A Peerless Grade Mortal Weapon can not only bear the blood and qi of each realm but also amplify it, releasing one and a half times the power.

According to Yang Ning's research, blood and qi are actually a type of field, which can be called the blood and qi force field. Therefore, the design of Mortal Weapons is simple: they are metal components capable of withstanding the impact of the force field energy.

Due to the different atomic structures of metal materials, their ability to bear the force field varies.

As for the Peerless Grade Mortal Weapon, its atomic structure resonates with the force field, thereby enhancing it.

Yang Ning didn't need to start testing from scratch. The extensive records of metal ore properties and compatibility in the library had already provided him with the answers, similar to big data. Yang Ning only needed to refine and digitize the vague data recorded by his ancestors using scientific methods.

The first thing he tried was forging Peerless Grade Mortal Weapons, which often required the use of millennium cold iron and ten thousand-year mysterious iron.

After looking at the pictures, Yang Ning recognized that these two types of iron were actually the same thing: an iron-nickel alloy meteorite. Under low-temperature conditions in space, the molecular structure changed, resulting in a surface pattern resembling crystal prisms.

Meteorites that fell from the sky and landed in the polar regions were called cold iron, while those that fell in temperate and tropical regions not covered by glaciers were called mysterious iron.

The crystal lattice pattern on the surface of this metal cannot naturally occur on planets and requires the low-temperature environment of space. It grows slowly, taking millions of years to form.

It sounded like a material for cultivation.

Cultivators believe that this lattice is a manifestation of the laws and has special significance. It does indeed have the ability to amplify the blood and qi force field.

However, since Yang Ning knew that mysterious iron was just an iron-nickel alloy, he naturally wouldn't specifically search for meteorites. He could directly prepare the iron-nickel alloy, which would have higher purity and quality than meteorites.

After some attempts in the Spirit Realm, he found that the best effect was achieved with an integrated union of nickel (14.2%), chromium (7.21%), and iron (78.59%), which is commonly known as stainless steel in modern times. However, the stainless steel prepared by Yang Ning in the Spirit Realm contained no impurities and naturally had much better performance than household stainless steel spoons.

But was this the best Mortal Weapon?

No.

Yang Ning directly brought over the metal formula from his previous life and found that 440C stainless steel, which had the highest hardness, wear resistance, and strength in the stainless steel family, commonly used for razor blades, high-strength bearings, surgical knives, and scissors, also demonstrated outstanding performance here.

Meteorites could enhance the blood and qi by 4-8%, the best iron-nickel alloy could enhance it by only 12%, the just mentioned iron-nickel-chromium alloy could reach 15%, but 440C stainless steel could reach an astonishing 21%!

Moreover, weapons made from 440C stainless steel had excellent performance on their own, and with the exaggerated enhancement, they could be upgraded by another level on the Peerless Grade Mortal Weapon!

But 440C stainless steel was still not the best alloy on Earth. The metals used for making aircraft engine blades and aerospace materials couldn't be even more exaggerated, right?

"What a great thing, but unfortunately, I can't bring it out now!" After all, experiments can be difficult, but doing business cannot be done like this.

Squeezing toothpaste is the right way!

Yang Ning opened the formulas for other Mortal Weapons.

The mainstream materials used for Low Grade, Middle Grade, and High Grade Mortal Weapons were still steel, but they emphasized a technique called "infiltration pattern" that could create patterns on swords and blades resembling snowflakes using special materials and forging techniques.

Different infiltration patterns resulted in different bearing capacities for the blood and qi force field. However, Yang Ning couldn't understand what materials were used for these infiltration patterns because they were not commonly known names from his previous life. Even the pictures were dark and looked like a muddy lump.

There were also some other formulas for Low Grade Mortal Weapons, but they were eliminated due to high costs, difficulty in casting, and not being conducive to mass production.

Yang Ning summoned a gray-silver longsword with black and white patterns on the blade and asked, "What material is this sword made of?"

"97.4% iron, 1.8% carbon, 0.6% silicon, and 0.2% vanadium, chromium, manganese, cobalt, nickel, and other rare earth elements!" Deep Blue answered.

This sword is a sword issued by the school. According to its grade, it should be a Middle Grade Mortal Weapon.

"Then let's give it a try!" Yang Ning integrated these materials according to the proportion of the sword and made a sword. Then he swung it heavily towards his own sword.

The sword in his hand broke with a sound, leaving only a small notch on the sword!

"Hmm?" Yang Ning scratched his head. Obviously, this is not a simple integration.

"This should be an alloy formed by combining forging technology and powder metallurgy technology!" Deep Blue said.

"But what is the iron-based material, and what powder should be used?" Yang Ning asked.

"Sorry, there is no corresponding information!" Deep Blue replied.

Yang Ning also scratched his head. The methodology is strong, but there are also times when it is powerless, such as in the field of materials science.

Perhaps the research on materials by people on Earth has not reached that level yet, far from touching the edge of the truth. Therefore, the study of materials is still at a semi-theoretical, semi-mystical level.

"Maybe I can learn divination techniques! Then I can decide what materials to use by flipping a coin."

Yang Ning put aside the idea of researching an alloy overnight. It was not unrealistic, but many terms mentioned in the books he saw in the library did not match the knowledge he learned in his previous life. At least he had to go to the market to see the actual objects.

But the tank can be started first.

This thing is very simple, just a four-wheeled vehicle that can be pedaled. The wheels can be retracted during battle, turning it into a turtle shell lying on the ground.

It can't fight humans, but it's just right for fighting brainless beasts.

In an instant, Yang Ning created it with a thought, then got in and drove it, without any problems.

It's a bit difficult for one person to operate, but it's just right for four people.

However, it seems that something is missing from this bare structure.

"Hmm, this armor doesn't need to withstand cannonballs, so I can add some spikes."

"It can be divided into upper and lower parts. The upper part can have a rotating function and two blades. When the blades rotate, they become a moving spiral shuriken. To facilitate passage, the blades should be retractable."

"The beasts may not be very large, they may be small and numerous. Firearms cannot be made yet, so let's use crossbows, Gatling crossbows. Four people can have four of them, and the four shooting holes can cover all directions."

"Let's also add a spray of poison and a pipe for spraying fire to deal with insects."

"Since it is stepped on, the normal square wheels can be abandoned. Instead, there can be two wheels in the front and two in the back, and the direction of the wheels can be adjusted. This way, it can not only move forward and backward but also rotate in place."

"Well, in case I'm unlucky and encounter a beast that is tough, powerful, and can overturn tanks, then let's add another layer and install a large bed crossbow! The weight of the bottom part also needs to be increased. It is said that a Fourth Layer body can wrestle with an elephant. An elephant weighs 8 tons, oh, then it's fine. My tank weighs 40 tons!"

Spirit Realm does not keep track of years, fortunately, things are not complicated.

Soon, a monstrous creature with a diameter of 6.5 meters and a height of 4.5 meters, divided into three layers, covered in spikes, and a huge barrel on top, was completely formed.

It has poison for close combat, water poison mist, fire spray for medium-range attacks, Gatling crossbows, and a spinning shuriken for long-range attacks. It has 50mm thick armor for protection.

Yang Ning couldn't figure out how to break this thing with a Fifth Layer beast's physical body.

The coolest thing is that it is still a cold weapon.

It can showcase Yang Ning's outstanding talent in refining, without being too ahead of its time.

"Come on, Deep Blue, give this tank in front of us a name. It should be fierce and majestic, elegant yet commanding respect and fear, and give a sense of security!"

"Tian Xing Jian, a gentleman should strive to become stronger, Di Shi Kun, a gentleman should possess great virtue and bear the weight of the world. It can be named Kun Shi, which is both heavy and aggressive, and gives a strong sense of security!"

"Not bad!" Yang Ning nodded. He also thought Kun was suitable. If he can create a flying device in the future, he will name it Qian Shi.

Since his transmigration, it has been twelve years. So let's name it Kun·12 tank, the full name being Kun·12 Mobile Shooting Tactical Platform.

"Hmm?" Yang Ning suddenly thought of something and raised his head abruptly.

In the sky, a Dragon Ball was shining in the Spirit Realm space like a bright moon.

With a thought from Yang Ning, strands of moonlight fell and shone on the Kun-style tank.

The next moment, without Yang Ning's operation, the tank in front of him actually moved on its own!
