Stepping out of the cavern of the underground dock, Todd followed Wayne and walked down the massive artificially dug passage into the depths of the cave.

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

Wayne said without looking back, "Walk through the northern part of Twilight City, and go straight to the bay near the Falling Star Mountains." ”

"Why put the guns of the battleship there for experiments?"

"First, it is for secrecy, and secondly, because the research and development and manufacturing of this weapon have relatively high requirements for the surrounding environment. ”

Todd nodded, no more questions.

A long underground tunnel, about 300 meters long in the front and back.

There are multiple checkpoints and sentry posts set up in the tunnel, and every few tens of meters, you can see the alien warriors of the Holy Cult Army, dutifully protecting everything at the end of this passage.

The second half of the tunnel is a gentle uphill slope. The further Todd went, the more he could feel something strange in the air.

The hairs on the whole body slowly stood up, and a faint crackling sound could be heard.

After walking the last section of the slope, Wayne walked through the Holy Cult Army kneeling on the ground, went straight to a closed stone door, and turned back and said, "Your Majesty, before entering, you and your attendants need to remove all the metal products from your body. ”

Todd nodded to the attendants beside him, and soon, his weapons and armor were removed and handed over to the Holy Cult soldiers for the time being.

The two orcs came to both sides of the stone gate, one left and one right, naked.

With a dull roar, the huge stone door was slowly opened.

A burst of air filled with a powerful charge burst out of the crack in the gate.

Todd slowly paced into the weapons lab built in the mountains, shocked by what he saw.

A huge railgun tens of meters long and more than a man high, made of keel, was installed in the middle of the laboratory.

Two huge keel columns, folded down and placed in parallel, are spliced together at the end to form a U-shaped track. The blue light, which is strong and weak, flows rapidly on the surface of the railgun like flowing water, 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 to the side of the railgun step by step, stretched out his finger towards the cannon body, and a powerful electric current penetrated from the surface, hitting his fingertips, and a trace of green smoke rose.

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

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

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

"This giant railgun, in terms of design principles and internal structure, refers to some pictures and introductions in the Heavenly Library, combined with the characteristics of xenomorphic creatures, and after nearly two years of research by scholars, the design drawings were finally finalized and construction began. ”

Wayne put on an insulating suit, stood almost five or six meters away from the railgun, and explained: "This weapon, roughly speaking, can be divided into four parts, namely the energy storage tank, the accelerator, the cannon structure and the firing switch. ”

"The energy tank is installed directly below the gun hull and has a total weight of nearly 29.65 tons, making it the heaviest component of the entire battleship. Such a heavy component not only provides energy for the entire railgun, but also has the role of stabilizing the gun body. ”

"The inside of the storage tank is made up of 36 storage modules connected in series, and each storage module is stacked with more than 900 Tesla parasites. These Tesla parasites, which resemble worms, can convert bioenergy into electricity and store it in the body. And keel parasites are the best containers to wrap around these Tesla parasites due to their congenital fire and electricity resistance. ”

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

Wayne confirmed: "That's right, there are probably so many Tesla parasites in the storage module. All insect bodies have been rigorously screened and cultured, and are hovered and fixed in containers to ensure the smooth flow of circuits and the stability of energy storage. ”

Todd asked, "With so many Tesla parasites using magnetic tracks to discharge electricity, how powerful are the projectiles fired?"

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

"The accelerator is the most important and complex part of the railgun, and using the good conductivity and high-power capacitance of the Tesla parasite, we wound and spiraled the worm body to form a U-shaped circuit reflow. ”

Wayne put his two thumbs together, and the other eight fingers were erected upwards: "When the worm body in this U-shaped orbit is stimulated to the nervous system, it will begin to activate the electric field in the body, so that the electric charge will move from one end of the U-shaped orbit to the other, so as to generate a super strong electromagnetic field between the planes of the two guide rails, so as to shoot out the cannonballs placed on the track." ”

Wayne took a copy of the experimental data from the assistant behind him: "At present, through repeated modifications and improvements, this railgun can already fire an object of about 11.5 kilograms at a muzzle velocity of 2,800 meters per second. ”

Todd walked directly in front of the railgun, crouched down to look at the track, and asked, "What about the range?"

"About 40 km, and this range can be extended again if the pressure damping of the shells is not taken into account. ”

Todd stood up and looked around, "What do cannonballs look like?"

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

A metal cannonball in the shape of a rugby ball about half a meter long was placed on the shelf in the car.

Todd looked in with his clairvoyant ability and said in surprise, "Here's ...... Spore parasites?"

"Yes. The last battleship used black powder as a means of propulsion to launch spore parasites, which were intolerably inferior in both range and hit. This time I sealed three spore parasites in a sealed metal shell. Not only can the range be greatly increased by the way of magnetic rail firing, but also the hit rate is extremely high because the electromagnetic thrust is continuous and uniform, unlike the unstable impact force when gunpowder explodes. ”

Wayne pointed to the railgun and said happily: "And, do you know, the keel parasite is a natural railgun material! The keel parasite can absorb heat, can conduct nerve messages, and the exoskeleton is an insulator, so even if the current power is high and the instantaneous heat is large, the keel can also cool the barrel in the shortest possible time, so that it can be fired as soon as possible next time." Not to mention ......"

Todd interrupted Wayne, pointing to the pitch-black cracks in the lab's mountain wall as a result of the violent explosion, and asked the question he had noticed early on: "What's going on?"

Wayne followed Todd's finger and looked at the marks on the rock wall, shuddering.

Seeing this, Todd accentuated his tone: "What the hell is going on?"

"Regarding the experimentation and development of the railgun, there was once a small accident. ”

"Minor accidents?!"

"At the beginning of the kinetic energy experiment of the shell, we deliberately increased the electrical power to the maximum in order to test the maximum range. But at that time, we forgot one thing. The high-power electromagnetic thrust can certainly maximize the muzzle velocity and range of the shell, but the unit pressure of the air resistance to the shell will also reach an extremely large peak. ”

Wayne sighed, "If the shell is solid, it doesn't matter. But at that time, we used shells, which were loaded with spore parasites......"

Todd understood everything: "So, the spore parasite, unable to withstand the instantaneous acceleration pressure, exploded directly before it flew out of the muzzle?"

Wayne lowered his head and whispered, "After that, we began to reduce the power of the electrical energy in a controlled manner, and suppressed the muzzle velocity of the shells to ensure that the deadly detonation pressure of the spore parasites was not caused. ”

Todd closed his eyes and shook his head bitterly.

Todd knew that on the road of scientific experiments and technological progress, there would inevitably be casualties among researchers, but when he really heard about such an accident, it still made his heart ache.

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

Wayne nodded yes, and after a pause, he suddenly looked up and asked, "Your Majesty, do you want to see the power of this giant cannon with your own eyes?"

Todd looked around at the experimenters, some of them were gray-haired scholars and scarred Holy Cult Army, but all of them had expectant expressions on their faces.

From the look in their eyes, Todd could see that these people were eager to be recognized by themselves, eager for the whole world to see their achievements for themselves.

Todd nodded at Wayne, "Load this cannon!
