please make me king

Chapter 847 Breakthrough
"Let's give it a try!" Zhang Shun frowned as he looked at Xiongguan in front of him.

No wonder Zhang Shun was worried, who would have thought that the Jindou Pass was three or four feet high and three or four feet wide, compared to most of the city walls that were more than ten feet wide, this frankly was a small earth mountain.

It turns out that Chinese-style city walls have been built with rammed earth as the main construction method since the records began.

"Mencius" Zeng Yun: Shun was born in the village, and Fu Shuo was in the building.

This Fu Shuo is said to be the prime minister of Wuding, the king of Shang. The so-called "starting between the plates and buildings" means that people built rammed earth walls before they made a fortune. This shows that my country's rammed earth technology has a long history.

The so-called "block building", the block is the splint, and the block is the wooden pestle.

In any method of building a wall, first clamp it with splints, put a mixture of soil, slaked lime and sand in the middle, and then vibrate and tamp it with a wooden pestle, and the city wall is completed.

Even in order to pursue the quality of the wall, most of the rammed earth of the city wall will add a lot of glutinous rice juice to enhance the strength of the city wall.

After the rammed earth wall is built, it looks like ordinary soil on the surface, but its strength is unexpectedly strong.According to relevant research in later generations, the strength of good-quality composite soil is equivalent to that of C15 standard concrete in later generations.

Although Zhang Shun didn't know how strong the Sanhe soil was, he looked at the thickness of Jindouguan, which was three to four feet thick.

Even if these are made of ordinary clay, it is enough to make people daunting.

What's more, this checkpoint was built during the Hongwu period of the Ming Dynasty. At that time, the country was newly established, the emperor was wise and his ministers were wise, and the war had just ended. Naturally, the grand pass built by it should not be mixed with any water.

The heavy "General Qingtian Cannon" slowly plowed deep ruts under the drag and push of dozens of cows and the crowd, and it took a lot of effort to move to the rebel position in front of the pass.

Zhang Dudu quickly ordered people to adjust the firing angle of the artillery, observe the shooting distance, and charge and reload the ammunition.

After everything was done, he hurriedly asked Zhang Shun for instructions: "His Royal Highness, the 'General Qingtian Cannon' is ready, please order!"

"Shoot!" Zhang Shun gave an order, and then the gunner got the order, and repeated the order: "Shoot!"

"Boom!" There was a loud noise, and the huge "General Qingtian Cannon" retreated violently, and then fireworks shot out from the muzzle of the cannon.

A huge iron bullet was like an arrow that left the string, broke through the smoke with a "shua", flew out, and with a "boom", it slammed heavily on the opposite Jindouguan city wall.

All of a sudden, the mud and sand fell down, and Jindouguan, which was as stable as Mount Tai, seemed to tremble!
The battlefield was silent, and I don't know how long it took before the gunpowder smoke spread and penetrated into the nostrils of nearby soldiers, causing a coughing sound, which woke everyone up.

Immediately, the rebel army under the city cheered: "Hey! 'The sky is invincible, and the city will be broken soon!"

From Zhang Shun's point of view, although the sound and light effects of the [-]-jin Hongyi cannon are good, the firepower alone is actually far behind.I and the others worked hard, but it was nothing more than throwing a [-]-jin iron bullet. If you want to blast through a city wall that is three or four feet thick with this thing alone, it is simply an impossible task.

However, for the people of this era, just hearing the deafening sound of the artillery, they can't help being heartbroken and looking pale.

Not to mention that just this one shot consumed twenty-five catties of black gunpowder.Coupled with the narrowness of Huangxiangban and the echo effect caused by the cliffs on both sides, this huge sound was even more intensified, and the ears of the people were buzzing, and they couldn't recover for a long time.

And the soldiers on Jindouguan City had already looked ashen, like a mourning concubine.Some trembled and fell limp on the ground; some peed on the spot; some had their heads like garlic and muttered in their mouths, saying that God's punishment has come!

Fortunately, the guard at Jindou Pass was still somewhat awake, he quickly drew his waist knife, and shouted loudly: "The thief just got two red barbarian cannons from nowhere, what's so strange?"

"My Jindouguan is as solid as gold soup, as solid as a rock, how can such a thing be broken?"

While yelling, he kicked his knife and slapped him, calling for the trembling soldiers to fight.

What kind of person is Zhang Shun, although he knows that the "General Qingtian Cannon" will not be able to break through the city in a short while, but the morale of the soldiers is now high, which is just an opportunity to use troops.

He quickly laughed and said: "God help me, send such a 'General Qingtian' to help our army, why should I break through this great pass!"

"Where is Chen Changji? Quickly order the artillery on the 'Xiaoyuanzhai' to suppress it, and the 'General Qingtian Cannon', 'Feibiao Gun', 'Golden Cannon', and 'Field Cannon' will all be fired from the city!"

"First break the gate, then break the city, and conquer the city in one go!"

Chen Changbing has followed Zhang Shun for a long time and has a tacit understanding.As soon as he heard Zhang Shun's words, he knew that he actually wanted to blast open the city gate and seize the opportunity to seize it.

He hurriedly pulled Dudu Zhang over, and ordered in a low voice: "A small part of the attack will attack the city wall, and most of the firepower will focus on closing the city gate!"

"This..." Dudu Zhang hesitated for a moment, apparently he already understood what Zhang Shun was going to do, "The original gate of the city was broken early, but now this is the thousand-jin gate from Jindou Pass."

"Not to mention whether the shot will hit the target, even if it hits, how can we break through the gate covered with a thousand catties of fine iron?"

"Give it a try, what if you win?" Chen Changzhu was actually a little unconfident, but after all, it was his brother's order, so he must not refute his face.

"Okay!" Dudu Zhang nodded. Anyway, there is no good way, just try it.

All of a sudden, the rebel positions were bombarded with artillery fire, and I don't know how many large and small shells poured towards Jindou Pass.

At this time, the artillery fired by the officers and soldiers was interfered by the artillery fire commanded by Li You on the "Xiaoyuanzhai", making it difficult to counterattack.

The rebels were even more unscrupulous, and kept repeating the steps of shooting, resetting, cleaning the barrel, charging, reloading, and shooting.

The city wall in front of Jindouguan had suffered countless shells, and the mud, sand and bricks fell down one after another, and the surface began to be riddled with holes.

From time to time, some flowering bullets fired by the Feibiao blunderbuss flew to the city wall, making a loud explosion sound.

It's just that this scene looks lively, but in fact it still can't move the enemy at all.

Zhang Shun frowned, and scolded in a low voice: "Shoot the city gate!"

Zhang Dudu couldn't help showing embarrassment, and was about to tell him that the shells of this artillery often didn't know where they missed, so how could they point out where to hit them?

Unexpectedly, there was only a loud noise, and a huge shell was smashing into the city gate, smashing a hole in the "thousand catty gate"!

Can it be done?Zhang Dudu couldn't help being surprised.

It turned out that due to technical problems, the shells and barrels of artillery in this era did not fit very well.

The diameter of the shell is usually much smaller than the bore, which is called "play".Generally, the "play" is between one-fifth and one-tenth of the diameter of the muzzle, so the accuracy of the artillery can be imagined.

When Zhang Shun cast the "General Optimus Cannon", he creatively adopted the process of building the barrel around the iron pillar.

According to Zhang Shun's level, it is still easy to design a straight and smooth cylinder. Although the barrel of the "General Qingtian Cannon" produced by the way may not be as smooth as the milled barrel, it is far better than the smooth one. .

And a huge benefit brought about by this is that the play of the "Sky General Cannon" is only about [-]%, and the accuracy of the shells far exceeds that of ordinary artillery.

The straight and round barrel brought Zhang Shun great convenience and good accuracy in calculating the axis of the barrel and drawing the aiming marks on the gun.

With the superimposition of these two benefits, the direct-pointing accuracy of the Qingtian General's cannon increased sharply, and it hit the gate of Jindouguan after only three rounds of calibration.

Driven by twenty-five catties of black powder, fifty catties of iron balls easily tore through the thousand catty gates wrapped in refined iron.

One, two, three... More and more shells hit the Qianjin gate, and the battered gate fell to the ground in a short while!

"The gate is broken, the gate is broken!" The rebels under the Dunbingxiong Pass couldn't help being ecstatic when they saw this, and they all shouted.

And Chen Changbing had already organized a "Shooting Team" and personally led the charge into it.

He vowed to take this pass in one fell swoop to relieve the hatred in his heart!
