Coil acceleration projection system Gustav equipment.

Before learning from the spider that this long-range delivery weapon system existed, Roland never thought that there would be a weapon with a range of more than 1,000 kilometers, let alone such a complex weapon system.

Similar to the Paris Cannon, K12E Train Cannon, Barbados Cannon, Baghdad Cannon, and other super-large diameter long-barreled guns, the 800mm caliber barrel has a 120-meter-150 times the diameter of the extra-long barrel. The step-by-step coil acceleration of the 4.8-ton cannonball can accelerate the 4.8-ton artillery shell to an ultra-high muzzle velocity of Mach 30 at a speed of 10 kilometers per second. With the help of this high-speed kinetic energy, which is above the first cosmic velocity, the cannonball can even fly out of the stratosphere and become a cannonball satellite orbiting the planet's surface.

Of course, Li Lin and the Wehrmacht had limited interest in peaceful uses for scientific exploration, and Yalfheim didn't have that many resources to spoil. Unless you're going to use this thing as a mass booster projector for launching spy satellites. Otherwise, what is fired from Gustav's cannon will eventually fall back to the ground, spreading death to the humans below.

Therefore, in addition to further refining the detailed design of the cannon, the scientists of the Wehrmacht worked the shells. After squeezing their imagination to the fullest, the technical team in charge of the super cannon project set their sights on the suborbital bomber project - Silver Bird.

As a member of the Doomsday Weapon, the long-term vision and meticulous planning of the Silver Bird Project are beyond ordinary people's imagination. In order to deal with enemies with vast strategic depth, and at the same time, it is necessary to take into account the emergency situation in overseas colonies. The Defense Forces called up aviation experts in the name of technical reserves. It is required to develop a vehicle with a range of 23,000 kilometers that can fly to any corner of the world to carry out bombing missions within an hour. Although the project itself has made limited progress, its theory of ascent/re-entry waverider flight has provided great inspiration to experts.

The shells on the drawing board began to deform rapidly, and after a large number of tests and demonstrations of the actual model, the samples of the drawing board were finally walked down, except for the outer fairing, the internal structure was difficult to find traces of conventional shells.

Further technical details are not clear even to spiders. It is only known that in addition to conventional grenades and armor-piercing shells, there are three special warheads -

It does not damage any buildings in the slightest, and even creatures hiding in bunkers can be killed;

After the explosion on the ground, the entire land will be deprived of grass for hundreds of years;

And - to turn a small island into a large bomb crater;

It doesn't matter which one falls on the head. Alcatraz Island and the one qiē on the island will all go down to history.

The distance is near. There is still about half an hour left.

- These things were completely beyond Minerva's imagination and could not be understood at all.

The rationale for not negotiating with terrorists was still within her common sense, super weapons, the destruction of an entire island - these things are not in the old myths. Never appeared in the real world. Swap for Minerva before the hijacking event. Only scoffed at this.

But right now, all kinds of strange-shaped biological weapons have appeared one after another, witnessing those alien biological weapons that can't be depicted even by imagination outside of knowing common sense. Her Royal Highness's common sense has been greatly shaken.

Now they are running towards prison. But Roland had no intention of dancing to someone else's script. The prison may seem safe, but it is actually a trap that brings the survivors together to ensure the best possible damage from the superbomb. But the guy with three heads probably didn't expect that the prison was also the only way to escape.

"Underground waterways?"

After listening to Roland's explanation, Minerva was a little surprised and quickly relieved.

Most of the time, Roland relied on this hidden path unknown to outsiders to infiltrate the prison, and then carried out the rescue along the way.

"We lured the crocodile out of the bathhouse sewer, but the big hole that the crocodile had washed out hadn't been plugged yet, and it was connected to the underground dock. From there, with the help of the dolphins left behind, it is still possible to escape by diving. ”

"Dive, dive?"

"There is a small diving gas tank on the underground dock, and the oxygen in it is enough to last for 15 minutes, as long as you are prepared for diving sickness, you should be able to catch the dolphin and swim out of the range of that guy in one breath. ”

"Uh...... Although there are a lot of things that I don't understand, in short, I have to dive into ...... Diving ?!!!!!"

The mournful roar comparable to the explosion of a 500kg aerial bomb penetrated the atmosphere, and the human-faced dog that secretly followed behind the surveillance foamed at the mouth and fell to the ground, and Roland, who directly suffered the murderous sound wave at close range, almost hit the street.

"You're kidding! Ju actually said he wanted to dive! Are you trying to kill me?!!!"

"Don't shake, don't shake!"

When she came to her senses, Minerva was already tugging at Roland's collar and swaying like a bartender fiddling with a shaker.

As a boy, it is really humiliating to be suppressed by a weak woman with a body. But before sighing about this, if Minerva doesn't calm down, something is likely to happen to Roland.

"Diving Diving Diving ...... Diving, that kind of thing, I can't believe it's unbelievable that I want to do something that a big water monster can do! Are you still a man?!"

"Even if it's not a big water monster, there are always people who can dive!

By making the divers all over the world lie down, Roland barely managed to hold himself up before the three-gauge halfpipe was shaken into a pool of yellow water, and the frantic shaking that almost turned his stomach bag upside down finally stopped.

Swallowing the sour water that poured up his throat, Roland looked at Minerva on the side in confusion. The petite lovely child seems to have encountered an extremely terrifying thing, clasping her arms without saying a word, and if you look closely, you can still find that her shoulders tremble slightly, where is there still the appearance of a dignified and generous princess on weekdays?

"It's hard to ......"

Thinking of a possibility, and without having time to think further, Roland asked Minerva:

"Y-can't swim?"

The delicate body trembled violently, and the emerald green eyes full of shame and melancholy glared at Roland. After a moment of silence, unassuming tears overflowed his eyes and fell with the movement of a nod.

Unbelievable.

Thinking so in his heart, considering Minerva's battered self-esteem, Roland still didn't say it.

As a royal daughter who received all kinds of elite education, Minerva, who was both civil and military, could not swim...... This kind of thing is a scandal-level event at all. But looking at her appearance, it seems that she is not afraid of her weaknesses being mastered, but she is full of fear of swimming itself. Could it be because of what psychological shadow does swimming leave?

Connect with someone's swimming training – those days in the pool with Smoothtooth, King Squid, Giant Eel, and Dragon. Although Roland didn't think that Minerva's coach was so excessive, he also tossed it with the mentality of the lion father to the lion cub.

It doesn't make much sense to delve into these things now, the important thing is to escape into the underground sewers first, and then the question is ...... It's a big deal to solve it with Li Lin-style means.

The decision had been made, and he was about to lead Minerva to run wildly again, when there was a sound of "Xi Xi Suo" in the grass. (To be continued......)
