C2871 Qi Bolin charged forward (1/2)

Siege warfare had always been a difficult technique to deal with since the ancient times. Although humans had entered the age of hot weapons and the appearance of artillery had greatly reduced the defensive capabilities of the city walls, the art of city construction had improved along with the technology.

Facing the development of artillery, the Prism Castle appeared as a unique means of defense at the end of the middle world. As the reinforced concrete technology matured, the human fortress gradually became more and more solid.

At the end of World War II, the German bunkers built in Berlin to prevent Allied air strikes were a typical exception. Until the end of World War II, none of the Allied army or air force weapons were able to destroy such a bunker.

By the time Germany surrendered, the Allies were ready to destroy the Nazi fortresses, and the engineers had calculated that the TNT needed to blow up was dozens of tons.

The British did not believe it and directly ordered the engineers to drill holes in the fortress. They installed 25 tons of explosives and after a loud explosion, the fortress was safe and sound. At that time, all the German who were watching on the side cheered crazily.

”This is German technology, this is German fortress, long live!”

”German Creation! It can't be blown away! ”

The Englishman's face was swollen like a pig's head. Finally, the British, out of face, had to gather 35 tons of explosives to blow up the fortress!

But after this lesson, the Allies no longer had any interest in the last remnants of the Berlin citadel, and no one pretended not to notice their existence.

These fortresses have been preserved until the 21st century and are now a unique tourist attraction for Berlin!

Fortress! It would always be an attack on one side of the nightmare, and in today's war, the French Prism Castle had become a scene of slaughter.

At this moment, the people finally realized the power of Sai Dang fortress. Originally, the outermost walls were just an appetizer, McMahon's real defense was relying on the Prism Castle and the surrounding buildings to carry out the street battle.

He was extremely clear about the military and scientific research in Europe at that time. He was very clear about the limited methods to attack cities, and he had no way to deal with such complex street fighting with Prism Castle s.

”How does the Prussian want to attack our castle? Aside from the large number of cannons, only the engineers were able to break through. Could it be that they will need to restore the soldiers of the middle world to the city? ”

”Using ladders or a car? Warriors, as long as the Prism Castle is here, we can injure the Prussian army to a great extent. Kill until their hearts ache, kill to the point where they have to talk to us about everything! ”

McMahon had already personally come to the front lines, he brought his staff officers deep into the Prism Castle, impassioned to motivate the soldiers' morale.

Sure enough, wherever McMahon appeared, the French army would always let out a long live roar, and the strength of their counterattack would suddenly multiply!

There were still a lot of generals like Flosad who served in the huge army of one hundred thousand. They organized and countered from different regions, moving their troops to fight and counterattack whenever the Prussian army's offense was thwarted.

The war had already turned into a brutal tug of war. Every charge and countercharge could tear countless pieces of flesh and blood, and many young lives would be lost in this cruel battle.

”The Prism Castle! Prism Castle … Is there really no other way to beat you? ”Damnit …” The Chinese soldiers during the bloody battle let out countless angry roars.

Just as the battle was about to begin, just as Flosad was reorganizing his forces and preparing to make a second assault, a gigantic black cloud slowly descended from the north side of the battlefield.

The soldiers on the Prism Castle stared dumbstruck at the gigantic beast in the sky. All of them forgot to fight, as the 303 metre long huge airship in the sky came crashing down like a mountain.

The huge propeller rotated in the air, three oil-fired boilers gave the balloon buoyancy, and the suspension chamber of the airship was filled with assaulting SPECIAL SERVICES.
