The underground differential machine network array of the largest library of this human race is said to use an endless stream of geothermal energy as energy, 365 days a year, 24 hours a day, can be used, driven by geothermal energy for differential computing and information processing, the entire library, there are a large number of information entry personnel and maintenance engineers to maintain the normal operation of this huge differential computer system, because when the generation of this soul tribulation realm, the library's differential computer system is normal, so at this time, Zhang Tie, even if he is alone in the library, can use this system normally.

After killing the father and son of the Han family, the biggest legacy left to Zhang Tie was the huge treasure trove of information in Xuanyuan Hill. 、

The largest library and database of the entire human race, at this time, became Zhang Tie's private study.

In addition to this library, the database of several major trade union organizations of the Terran race at the headquarters of the Xuanyuan Hill Trade Union was also completely open to Zhang Tie.

This is Zhang Tie's biggest gain in Xuanyuan Hill.

Compared with such a harvest, the few Soul Tribulation Fruits that were used up at the beginning don't seem so regrettable now.

Next to the operating table of the inquiry machine, there is a corresponding "Operation Instruction Manual", Zhang Tie picked up the manual and quickly flipped through it, and he already knew how to operate.

In the sound of clicking, the metal keyboard is very textured, and the universal remote sensing crystal communication information code characters are already familiar to Zhang Tie, and Zhang Tie quickly entered the keywords he wanted to query information in the machine.

There is only one key word for Zhang Tie's query - kinetic weapons!

Hit enter, and the subtle and pleasant sound of gears in the room is moving. Zhang Tie waited for a minute, and the huge black metal curtain wall in front of him. Countless tiny metal pushpin-like bumps began to invert and turn white. These white dots, connected together, form a series of words, and this series of words are a series of book lists and information materials.

What did not surprise Zhang Tie was that these materials, judging from the time suffix, were basically derived from the research of kinetic weapons by the Terrans before the cataclysm.

……

In the first inquiry, Zhang Tie found a total of more than 40 related materials and books. Zhang Tie operated the button on the console and directly opened the first book of materials - "The Future of Kinetic Weapons from the Tunguska Explosion......

A series of words appeared on the metal pixel display curtain wall in front of Zhang Tie.

For the next three hours, Zhang Tie was in the room, eagerly absorbing all the knowledge about kinetic weapons.

Kinetic weapons are different from traditional weapons, the traditional weapons developed by the human race before the cataclysm, such as various missiles, bombs and nuclear weapons, rely on explosions to kill and destroy targets, while kinetic weapons do not kill targets by exploding. It relies on its own powerful kinetic energy to destroy the target.

Don't think that weapons that use kinetic energy to destroy targets are not very powerful, it is said that the inspiration for the development of kinetic weapons by Terran scientists at that time came from the big explosion caused by a meteorite hitting the ground that occurred on a subcontinent of Terran before the cataclysm, when a meteorite hit the ground with great speed and mass. The kinetic energy and power it released have exceeded the explosive power of 1,000 atomic bombs and the high-speed impact of a meteorite. In the blink of an eye, thousands of square kilometers of land were reduced to a scorched earth.

The power of kinetic weapons. Only velocity is related to mass, as long as an object can reach a tremendous velocity. Even if the mass of that object is small, it can bring great power.

Among all the kinetic energy weapons invented by the Terrans before the mansion change, how to obtain huge speed has become the key point in the power of a kinetic weapon.

In order to obtain a huge speed, people have tried all kinds of ways, the electromagnetic cannon is to use the electromagnetic acceleration principle to make the projectile it launches to obtain a huge speed, and the space-based kinetic energy weapon directly puts the electromagnetic cannon on the synchronous orbit of the planet and becomes a railgun, and the projectile launched by the railgun towards the ground not only obtains the huge muzzle velocity brought by the electromagnetic gun, but also obtains the increase in gravitational acceleration caused by gravity after returning to the atmosphere, and the speed will be faster and faster. When a railgun's kinetic energy projectile falls on the ground, the speed has reached hundreds of Machs, and the power is very terrifying, like the space-based kinetic energy weapon mentioned in the "God's Spear Project", which is to launch an "iron spear" pushed by a rocket booster from space at the ground target, so that the "iron spear" can obtain the same double acceleration ability as the railgun projectile, so as to destroy the target on the ground.

Before the cataclysm, mankind had invented the interception technology of ballistic missiles, and the role of all nuclear weapons was discounted, but the strike of kinetic weapons could not be intercepted. It is precisely because kinetic energy weapons are powerful and cannot be intercepted that before the cataclysm, all countries of the Terran race rushed to develop kinetic weapons to replace nuclear weapons as a new strategic deterrent.

Zhang Tie also saw a table in those materials and books, which listed the comparison of the kinetic energy power of various weapons invented by human beings, and it was precisely by seeing the comparison of the kinetic energy power of various weapons on that picture that Zhang Tie finally realized how terrifying the hammer he killed the seven knights of the Holy Light Empire.

The explosive power of Davy's small tactical nuclear weapon, the lightest tactical nuclear weapon invented by mankind before the cataclysm, was 41.8 billion joules, which is equivalent to the explosive yield of 10 tons of TNT explosives, and the energy of his own hammer is 45 billion joules, that is to say, the kinetic energy power of his hammer is 10 percent greater than that of a small tactical nuclear weapon.

The power of nuclear weapons is spread, while the power of kinetic strikes is more concentrated, so it brings greater lethal effects.

With such power, coupled with his own battle qi and the two killing effects attached to Thor's hammer, the seven divine sticks of the Holy Light Empire bore the brunt of it, and naturally they were wiped out as soon as possible.

And among all the materials, the one that made Zhang Tie feel the most energetic was the article "On the Application of Hypersonic Aerospace Vehicles in the Field of Strategic Kinetic Energy Weapons"——

That was the idea of a strategic kinetic weapon put forward by a Chinese scientist before the cataclysm, to create a hypersonic aerospace vehicle that can reach dozens of times the speed of sound, such a vehicle in the flight process, even if it is just to throw an iron rod at the target, the speed of the iron rod when it leaves the aircraft is also dozens of times the speed of sound, such a speed, in the process of flying down from the air, and then accelerate twice, the power of the iron rod falling on the ground is about the same as a nuclear weapon.

Looking at this article, Zhang Tie's face became strange, because he felt that this idea seemed to be talking about his current ability - to use the flying ability of the Divine Emperor to make himself reach more than ten times the speed of sound, and then throw a flying spear at the target......

At that time, the velocity of the flying spear was ten times the basic velocity of the speed of sound, plus the muzzle velocity of the throw, plus the increase due to the acceleration of gravity......

Of course, the 6,800-kilogram Thor's hammer can't be thrown out to attack people casually, but if you fly a spear, don't you have as many as you want?

The flying spear throwing skill of the thunder in his palm can already kill the war spirits below the knight in an instant, and if the weight of the flying spear thrown by the thunder in his palm increases several times, and the speed increases by more than ten times the speed of sound, how strong will the kinetic energy on the flying spear be, and how powerful will it be?

Zhang Tie stood in the room for a while, then slapped his head hard, and rushed out of the room like a gust of wind......

……

Just a few minutes later, the door of the armory room of a military camp of the Black Armor Army in the north of Xuanyuan Hill slammed and directly shattered, and Zhang Tie, who had a little excitement on his face, then walked in.

Because the space equipment could not be used in the realm of soul tribulation, to verify that idea, Zhang Tie could only find ready-made tools in the realm of soul tribulation.

Fortunately, in a place like Xuanyuan Hill, gathering the world's wealth and goods to strengthen the army, it is very simple to find something, especially things like armor and flying spears, these things, in the ordnance and armament warehouses of the military camp of the Taixia Shang Fourth Army guarding Xuanyuan Hill, it is absolutely impossible to find them.

The Black Armor Army is worthy of being the Black Armor Army, and all kinds of weapons and equipment in this armory are the most sophisticated goods, and all kinds of things are available.

Zhang Tie didn't want much things, he first came to the place where the armor was stacked in the armory, found a set of bronze fitted metal armor, put on the metal combat boots in the metal armor, tied the metal belt, and then put on the metal cuirass and metal bracers, and after trying to control the rapid flight, he came to the place where all kinds of weapons were placed, found a few of the heaviest flying spears stacked here, and then left the armory.

Zhang Tie, who had left the armory, flew up in the blink of an eye, and under the speed of the Swift Movement and the ability of the Divine Master, Zhang Tie's speed quickly reached the limit speed he could reach now - 3487 meters per second.

The heaviest flying spears in the armory, each 56 kilograms, but in his hand, Zhang Tie weighed it, and still felt that it was too light, like a straw, but now he mainly wanted to test its power, so Zhang Tie didn't care.

Zhang Tie didn't deliberately choose any target, flying in the air at a height of more than 1,000 meters, he just looked at a building with more than 20 floors below, and then he threw the flying spear in his hand hard...... (To be continued.) )
