Walking out of the cavern of the underground dock, Todd followed Wayne and walked into the depths of the cave along the huge artificially dug passage.

Feeling the temperature drop around him, Todd asked, "Where does this road lead?"

Wayne said without turning his head: "Cross through the northern part of Twilight City to the bay near the Falling Star Mountain Range."

"Why put the battleship's artillery there for experiments?"

"One is to keep it secret, and the other is because the development and manufacturing of this weapon requires relatively high requirements on the surrounding environment."

Todd nodded and stopped asking questions.

A long underground tunnel, together with the front and back, is almost three hundred meters in length.

There are multiple checkpoints and guard posts in the tunnel. Every tens of meters, you can see the foreign fighters of the Holy Religious Army, guarding everything at the end of the passage loyally.

The second half of the tunnel is an upward **** with a gentle slope. The more Todd moved forward, the more he could feel a strangeness in the air.

The hair on the top and bottom of the body slowly stood up, and a faint crackling sound could be heard.

After walking the last section of the slope, Wayne passed through the crusaders kneeling on the ground, and went straight to a closed stone door. He turned around and said, "Your Majesty, you and your attendants are required to get rid of everything. Metal products."

Todd nodded to the attendants around him. Soon, the weapons and armor were taken off and handed over to the soldiers of the Crusades.

Two orc spirits, naked to the left, came to each side of Shimen.

Accompanied by a dull low roar, the huge stone gate was slowly opened.

A burst of air filled with a powerful electric charge came out magnificently from the gap in the door.

Todd paced slowly into this weapons laboratory built in the mountains, and was shocked beyond words by the scene before him.

A huge railgun, tens of meters long and taller than a person, constructed from a keel, is installed in the middle of the laboratory.

Two huge keel straight columns, laid down and placed in parallel, are spliced ​​into a U-shaped track at the end. The blue light, which is strong and weak at the time, is like flowing water on the surface of the railgun, flowing quickly, making the thing in front of you look like an alien weapon from the future.

Under the gaze of hundreds of laboratory staff, Todd walked step by step to the side of the railgun and extended his fingers towards the gun body. A powerful electric current penetrated from the surface and hit his fingertips. Up, a hint of green smoke rose.

"Your Majesty, be careful!" Wayne said two steps closer: "The energy pool is being charged, and the shell of the barrel is not fully installed. It is very dangerous to touch it at this time!"

Todd smiled and wiped the dust off his fingers, using perspective and eagle eyes to look inside the railgun.

One after another Tesla parasites emitting dazzling blue light are fixed inside the gun body, forming an electromagnetic circuit in a special U-shaped keel orbit filled with culture fluid.

"The design principle and internal structure of this giant magnetic railgun are based on some pictures and introductions in the Heavenly Kingdom Library, combined with the characteristics of alien organisms. After nearly two years of research by scholars, the design drawing is finally finalized. And start building."

Wayne put on an insulating suit and stood almost five or six meters away from the magnetic rail gun. He explained and analyzed: "This weapon can be roughly divided into four parts, namely the energy storage tank, the accelerator, and the gun body structure. And the firing switch."

"The storage tank is installed directly under the gun body, with a total weight of nearly 29.65 tons. It is the heaviest part of the entire warship. Such a heavy component provides energy for the entire railgun while also having stability. The role of the gun body."

"The energy storage pool is composed of 36 series-connected storage modules, and each storage module stores more than 900 Tesla parasites. These Tesla parasites resembling worms can transform biological energy. It is electric energy, and it is stored in the body. The keel parasites are the best container to wrap these Tesla parasites due to their inherent fire-proof and electricity-proof performance."

Todd listened and calculated an account: "36 power storage keel modules, each module stores 900 Tesla parasites, so the total number of Tesla worms is 32,400?"

Wayne confirmed: "Yes, there are probably so many Tesla parasites in the power storage module. All the worms are strictly screened and cultivated, and hovered and fixed in the container to ensure the circuit Smooth flow and stability of energy storage."

Todd questioned: "So many Tesla parasites use magnetic tracks to discharge, how powerful are the shells they fire?"

"Your Majesty, the next thing I want to explain is the accelerator."

"The accelerator is the most important and most complex part of this railgun. Using the good conductivity and high-power capacitance of the Tesla parasite, we wind and spiral the worm and form a U-shaped circuit for return. "

Wayne connected the two thumbs, and the other eight pointed upwards: "When the worm in this U-shaped orbit is stimulated to the nervous system, it will start to activate the electric field in the body, allowing the charge to flow from one end of the U-shaped orbit. Move to the other end, so that a super electromagnetic field is generated between the two rail planes, and the shells placed on the track are shot out."

Wayne brought a piece of experimental data from his assistant behind him: "At present, through repeated modifications and improvements, this railgun can launch objects of about 11.5 kilograms at a muzzle velocity of 2800 meters per second. ."

Todd walked to the front of the railgun, knelt down and looked at the track, and asked, "What about the range?"

"About 40 kilometers, if the pressure damping of the projectile is not considered, this range can be extended again."

Todd stood up and looked around: "What does a cannonball look like?"

Wayne clapped his hands. Later, two elf staff members cautiously pushed a wooden cart and walked slowly towards Todd.

A rugby-shaped metal cannon ball about half a meter long was placed on the shelf in the car.

Todd looked inward with a clairvoyance ability, and said in surprise: "There is... a spore parasite in it?"

"Yes. The last battleship used black powder as a means of propulsion to launch spore parasites. Both the range and the hit rate were unbearable. This time I enclosed three spore parasites in a sealed metal shell. Among them. Not only can the range be greatly improved through the magnetic track launch, but also because the electromagnetic thrust is continuous and uniform, unlike the unstable impact force that occurs when gunpowder explodes, the hit rate is extremely high."

Wayne pointed to the railgun and said happily: "And, did you know that keel parasites are natural materials for railguns! The keel parasites can absorb heat and transmit nerve information, and the exoskeleton is an insulator, so even No matter how high the current power is, no matter how large the instantaneous heat is, the keel can also cool down the barrel in the shortest time so that it can be fired as soon as possible next time. What's more..."

Todd interrupted Wayne, pointed to the dark cracks formed by the violent explosion on the wall of the laboratory, and asked the question that he had noticed early on: "What's the matter?"

Wayne followed the direction of Todd's fingers and looked at the traces on the rock wall, shaking his whole body.

Seeing this, Todd increased his tone: "What is going on?"

"With regard to the experiment and research and development of the magnetic railgun, there was a small accident."

"Small accident?!"

"In the first kinetic energy experiment of shells~lightnovelpub.net~, in order to test the maximum range, we deliberately increased the electrical power to the maximum. But at that time, we forgot one thing. The high-power electromagnetic thrust can certainly make The initial velocity and range of the projectile are maximized, but the unit pressure of the projectile by the air resistance will also reach an extremely large peak."

Wayne sighed: "If the shells are solid, it doesn't matter. But at the time, the shells we used contained spore parasites..."

Todd understood everything: "So, the spore parasite exploded just before flying out of the muzzle because it could not withstand the instantaneous acceleration pressure?"

Wayne lowered his head and said in a low voice: "After that, we began to restrain the power of the electric energy and suppress the muzzle velocity of the shells to ensure that the spore parasites would not cause deadly explosive pressure."

Todd closed his eyes and shook his head in anguish.

Todd knew that on the road of scientific experimentation and technological progress, there would be casualties of researchers, but he was still heartbroken when he heard about such accidents.

Todd's voice was a little hoarse: "Copy the list of victims and send it to the palace..."

Wayne nodded and said yes. After a moment of pause, he suddenly raised his head and asked: "Your Majesty, do you want to witness the power of this cannon with your own eyes?"

Todd looked around at the experimenters around him. Among them were gray-haired scholars and scarred Crusaders, but all of them showed expectant expressions on their faces.

From their eyes, Todd can see that these people are eager to get their own approval, eager to let the whole world witness their achievements.

Todd nodded to Wayne: "Load this cannon! Let me see what you can do!"
