Xia Pingan's apartment is small, but Shangjingcheng is huge!

Just when Xia Ping'an was bathing in the Yiyang Shenquan in the small apartment he rented, in the underground of Shangjing, the dark and deep place that ordinary people have only heard of but never visited, a fierce battle About to start.

There are almost tens of thousands of densely packed magic fire spiders and magic liquid spiders crawling out of the magic cave in the underground world.

The target of these magic fire spiders and magic liquid spiders is a majestic and fiery city of steel located under the upper capital.

The big spiders that crawled out of the dark caves and various caves, crawled through the dark cracks and rock walls full of monster bones, from the ground, from around the rock walls, toward the steel The city advances.

The whole underground is full of rustling noises made by those spiders marching, like quicksand and mudslides surging towards the city of steel in the dark underground.

That steel city has steep walls more than fifty meters high. The walls of the city walls, like a warrior in armor, are also covered with chunks of rough but hard steel armor.

The city was in full swing, and the smoke from the steam made the city walls steamy, as if in a thick fog.

The abnormal movement of the monsters has been discovered. The steam boilers in the city wall are beginning to pressurize, and the powerful city defense equipment is being activated. On the wall of the steel city, there are six or seventy-meter-long high arrow towers. Propelled by steam, gears, and mechanical devices like a giant's arm, it rises from the city wall, spreads its teeth and dances its claws, and extends toward the outside of the city high in the sky, like the thorns on a porcupine body, and like an octopus caught on the hand. The spear aimed at the big spiders surging from the caves and caves in the distance.

On those moving arrow towers, a circle of apertures rose up, and each of the summoners had begun to prepare for spells.

On the city wall, the high temperature and red light generated by the steelmaking furnace made the city red light in the misty steam.

The smelted steel was poured down along the grooves of the city wall, repairing the damage of the city wall, and also bringing a stronger defense to the city wall.

Such battles are often encountered in dungeons.

All the soldiers wearing armor and holding heavy muskets have all gone to the Tibetan soldiers' cave of the watchtower and are in a state of combat.

The reserve team of the ruling army's powerful summoners is ready to go.

On the wall, rows of black muzzle windows opened, and the muzzle of a murderous cannon protruded from the wall, and the artillery was ready.

The big spiders surging in the distance are gradually entering the shooting position that the artillery has already calibrated.

On the highest part of the tower of this majestic city, two men wearing the black and golden robes of the Dark Ares Sect and the Senate Bishop are standing one to the other in their thirties. Their faces are determined and noble. They are wearing patriarch robes and wearing patriarch robes. Next to the middle-aged man with the crown of the patriarch, he coldly looked at the monsters pouring from the cave.

The monsters outside the dungeon were raging, but the three of them all looked calm.

"His Royal Highness, the artillery is ready!" The old man with a quiet temperament and black hair standing on the left side of His Royal Highness of the Dashang Kingdom said calmly.

If Lan Wuwei is here at this moment, and seeing the calm and quiet old man, he will definitely give a great greeting, because this old man is Lin Yi, the commander of the Judging Army, and the participating bishop of the Dark War God Sect of the Shang Dynasty. One of the most powerful summoners in the advanced six suns realm.

The underground city below the upper capital is stationed by the ruling army.

The man standing in the middle who was called by Lin Yi as his Royal Highness was Beitang Wangchuan, the prince of the Great Shang Kingdom.

The man standing on the right side of Beitang Wangchuan looked a little older, his eyes flashing, his breath was strong, even a little aggressive.

This person was Fei Yulong, Minister of Navy of the Great Merchants, and also a great figure in the capital.

When Lin Yi spoke, Fei Yulong's face was calm, his eyes were inadvertently swept towards the seven brand new mobile forts on the city wall. The fort was reinforced and modified, and the fort was lined up with seven doors. For Fei Yulong Some unfamiliar cannons400 mm caliber, longer barrel, and larger diameter can be daunting at first sight.

As the Minister of the Navy of the Dashang State, Fei Yulong knows very well what the current level of the Dashang Artillery Research Institute is. Just a few months ago, the Dashang Artillery Research Institute just captured the number of the 310mm main gun A technical difficulty.

Therefore, the seven 400mm cannons in front of him are by no means the result of the Firearms Research Institute, and he has never heard of any of the several gun factories in Dashang that have produced artillery of this level.

Today, His Royal Highness invited him to the dungeon, in the name of seeing the power of the main guns of the future naval battleships of the Great Merchants.

Where did those cannons come from? Fei Yulong was full of doubts.

Hearing Lin Yi's words, Beitang Wangchuan nodded and said softly, "Then try the power of those main guns..."

Lin Yi looked at the artillery commander staring at this place on the far wall, and nodded slightly. The right hand raised by the artillery commander suddenly swung down like a guillotine.

"boom"

"boom"

The main guns on the city wall roared, and flames burst out from the muzzles of the main guns with a caliber of 400 millimeters.

At the moment of firing, all the turrets shrank back, and the turret under the main gun was also trembling. Although the powerful hydraulic shock absorption system resolved most of the impact, the power of the giant gun still made the city wall and The air on the wall trembled.

The cannonball screamed and flew out from the muzzle, with huge kinetic energy, flying nearly 30,000 meters in the dark sky of the underground world, like meteors that pierced the sky, and then fell on those surging from the magic cave. Coming inside the army of spiders.

The explosion, the roar, the earth shakes the mountain...

When a cannonball falls, it is a fire that swells fiercely. The fierce firelight is like a bunch of blood-colored flowers blooming in the dark underground. Once it hits the ground, it can swallow and shred the big spiders within dozens of meters around it.

The defenses of those big spiders are not weak, but under the terrifying heat and shock waves, each spider is either turned into coke or broken into pieces.

The cannon on the city wall continued to roar, and directly built a wall of death under the ground 30,000 meters away from this majestic city...

The power of this main gun surprised the three people on the tower silently watching the distance.

The artillery observers and commanders who were looking at the distance with artillery observation instruments and remote viewing capabilities were also shocked and excited.

The range of 30,000 meters is 30% longer than the range of the main guns of the previous generation of the Dashang country. The power of the high explosives filled in the shells is also completely different from the past. It is two levels...

For all monsters, this is a big killer.

Those cannons are still roaring!

The automatic loading machine on the turret is stuffing huge cannonballs into the barrel, firing them uninterruptedly.

The quality and stability of that cannon is very high...

It is a pity that the number of cannons is still a little bit less, and there are constantly big spiders passing through the death barrier 30,000 meters away, continuing to charge, and approaching the dungeon.

When the big spiders approached more than 20,000 meters, the other main guns on the city wall began to roar.

The entire dungeon was filled with smoke and gunfire rumbling, and the shells fell one after another, tearing the big spiders rushing towards the dungeon to pieces.

Fei Yulong finally couldn't help it, "His Royal Highness, where did the seven artillery come from?"

His Royal Highness smiled slightly, "If our navy and dungeons are equipped with such a weapon, how does Master Fei feel?"

"If our navy has such huge artillery, coastal and coastal defenses will be indestructible. It will be easier to clear the sea monsters and pirates. At the same time, the navy will greatly reduce its dependence on the summoner. His Royal Highness has not yet said where the huge artillery comes from. Yes, our Artillery Research Institute shouldn't have the strength to make this kind of artillery!"

Lin Yi next to him said, "This artillery comes from the Great Ting Kingdom in Mujiao Prefecture. His Royal Highness and the Great Ting Kingdom have completed a transaction. The Great Ting Kingdom will transfer several key points for the production of this artillery to our Dashang Nation. Technology, in the future, our large merchant countries can also produce artillery and shells equipped with this caliber!"

Fei Yulong frowned slightly, and he couldn't believe it, "Can the Great Ting Kingdom make artillery of this level? The firearm technology of the Great Ting Kingdom is similar to that of our Dashang before. How can it be so advanced? This artillery involves many kinds of artillery. The key technology ~www.mtlnovel.com~ is just the alloy steel that casts the cannon body, which can withstand the high chamber pressure in the barrel of such a large-caliber and double-caliber gun. The material team of our Artillery Research Institute has overcome this problem for several years. No results yet!"

"There was a genius in the Great Tingguo. It was that person who made the artillery research of the Great Tingguo advance by leaps and bounds and threw us away!" His Royal Highness said softly, and shook his head slightly, "The Great Tingguo is lucky. of!"

"Genius, who is it?" Fei Yulong asked.

"The Great Tingguo has always kept the person's identity secret and does not reveal the slightest tone, so the outside world is still unclear. However, there is news that the person may become the new dean of the Great Tingguo in the future. Got it!" His Royal Highness said softly, and then looked at Lin Yi, "The iron and steel plants and gun factories in the upper capital are currently preparing for technological transformation. I will let the following digest the technologies I obtained from the Great Court as soon as possible. During this period of time, the capital city may not be peaceful, so I ask Master Thorin to take care of it, and don't let those shameful things affect major events!"

"The ruling army will do its best!" Lin Yi leaned slightly, then looked at the demon cave in the distance, and reminded, "In the past six months, your Majesty's Northern Expedition, this underground demon cave has become more frequent. The more complicated it is, the safety of the entire Upper Capital lies with His Royal Highness. Please pay more attention to His Highness!"
