Rumble!

With a loud bang, a thick cloud of smoke rose up.

Without waiting for the smoke to clear, Han Zhen set up his horse and galloped towards the city wall three hundred steps away, followed by Huang Kai and Lao Jiu.

A few steps in front of the city wall, a pair of hanging foot armor was also fixed with a wooden frame.

At this moment, the step armor had become a sieve.

The city wall behind is densely covered with bullet holes, and iron nails and thistles have broken the green bricks and embedded them deep in the rammed earth.

"Shhh

Huang Kai and Lao Jiu looked at the miserable situation of Burenjia, only to feel that their scalps were numb, and they couldn't help but gasp.

This is a full of foot armor, a hundred steps away, the divine arm crossbow can't shoot through.

But at the moment, it's like paper.

More than a dozen bullet holes through it tell the story of the foot armor.

Touching the bullet holes on the Buren's armor with his hand, Huang Kai swallowed his saliva and said in horror: "It's so powerful, I'm afraid that even the giant shield can't stop it." The two armies are engaged, and as soon as the cannon goes down, the enemy's front will fall. ”

In fact, the lethality of field artillery is not much different from that of clay pot firearms.

The difference is in the range, which can be fired from 300 paces away, while the clay pot can only be thrown at a distance of twenty or thirty paces.

Although the arrows that can be tied to the crossbow of the three-bow bed can be used, the requirements for the operator are too high, and the time of the explosion needs to be strictly controlled.

The explosion was early, and it exploded in mid-air.

When it is late, the enemy has time to prepare.

The field artillery was much simpler and crude, loaded with gunpowder and ammunition, then aimed at the enemy, and the ignition was over.

"I don't know, after all, it's three hundred steps."

Lao Jiu shook his head, skeptical.

The huge shield of the heavily armored foot soldier has an amazing defensive power.

The inside is hardwood, the outer layer is a thick iron sheet, and the middle is also filled with kapok to absorb shock, which can block the crossbow of the god arm.

Han Zhen instructed: "Just give it a try, Huang Kai, go to the armory and get a giant shield." ”

"Order."

Huang Kai stepped on his horse and ran towards the ordnance.

Returning to his original position, Han Zhen looked at the swarthy field cannon.

It took more than a month, and with the efforts of dozens of craftsmen, this pure iron field cannon was finally forged.

The whole gun body is about one meter long, the muzzle diameter is five centimeters, and the front of the gun body is thin and thick.

In particular, the tail of the gun is like a semicircular large iron ball, which is designed to enhance the service life of the field gun.

Early artillery, both in the East and the West, was designed to be thin in the front and thick in the back.

Because the iron-smelting technology at this time was immature, and the tail of the gun was the place where the gunpowder burned and exploded, the thickening treatment could fill more gunpowder and withstand a higher explosion.

In addition, every foot on the cannon body, there is an iron hoop, which is also used to strengthen the cannon body.

Taking advantage of Huang Kai to get the giant shield, Han Zhen asked, "What is the cost of this field cannon?" ”

Craftsman Yuan replied truthfully: "The county magistrate, the cost is about one hundred and twenty yuan. The raw materials are not expensive, mainly the labor costs of the craftsmen. ”

Pig iron is very cheap, Han Zhen now has his own iron mine, a pound of pig iron counting manual transportation, etc., the mining cost is only a dozen yuan.

This field gun is only five or six hundred catties, and the raw materials are no more than forty, and the rest is the labor cost.

After all, it is forged, not cast, and it is extremely troublesome to manufacture.

First, a rough model should be formed by hot forging, and then it should be shaped and refined by cold forging.

The difficulty lies in the barrel, which needs to be smooth and straight.

"The cost is okay."

Han Zhen nodded, the price was within his budget.

Then he asked, "How much can you produce in a month?" ”

Hearing this, Craftsman Yuan smiled bitterly: "Don't hide it from the county magistrate, this field cannon forging is extremely difficult, and non-skilled craftsmen are not competent, with the current number of blacksmiths in the engineering academy, even if they are familiar with the method of forging, they can only produce three at most in a month." ”

In comparison, the previous iron wood cannon was much easier.

Three doors a month?

Han Zhen frowned slightly, this was far from his expectations.

Thinking of this, he ordered: "I don't care if you expand the blacksmith recruitment or improve the method of blacksmithing, the minimum production of ten doors a month is the bottom line." ”

"This ...... Wechen understood. ”

Craftsman Yuan had to respond with a bitter face.

Ten doors a month, and by the summer harvest next year, it is estimated that more than 100 doors can be saved.

Although it was much less than the expected 500 guns, the destructive power of more than 100 field guns in a salvo was still very considerable.

While speaking, Huang Kai took a giant shield.

After replacing Buren A, Han Zhen was about to reload the gunpowder, but he saw Lao Jiu on the side and said greedily: "County magistrate, can you let me have a good time?" ”

"Okay!"

Han Zhen moved out of the way and advised: "Five spoons of gunpowder is enough, don't fill too much." ”

After several previous test shots, he had figured out how much to reload.

Five spoonfuls of power is enough to break through heavy armor at a distance of three hundred steps.

If he had more, he would have been afraid of exploding.

"I'm provincial."

Lao Jiu nodded, and began to load gunpowder excitedly.

No man can resist the temptation of a cannon, any more than a child can resist a cannon.

After loading, he followed Han Zhen's example, picked up a wooden stopper and stuck it into the barrel of the gun, compacting the gunpowder.

Tribulus terrestris and nails were then stuffed into the barrel.

Inserting the lead, Lao Jiu took out the fire fold with excitement on his face, and ran away after lighting it.

Rumble!

A loud bang exploded in my ears, and hundreds of thistles and nails erupted and slammed into the walls and giant shields in front of me.

"It's so fucking cool!"

Lao Jiu's face was full of excitement, happy like a child of about 200 pounds.

Huang Kai proposed: "Brother Jiu, let me try it next time." ”

Lao Jiu pouted and said: "I haven't had enough fun, besides, you're fucking anxious, this thing is in the barracks in the future, you don't want to fight it." ”

"Wow!"

Huang Kai's eyes lit up suddenly.

The three of them came to the wall again, and saw seven or eight small holes in front of the shield.

Tribulus terrestris and iron nails shot through the outer layer of iron, and from the back of the shield, you could see the traces of protrusions, but they did not penetrate the entire shield.

Black powder is not as good as yellow powder, even if Han Zhen used distillation technology to purify saltpeter and sulfur, but the power is still very different from yellow powder.

However, with the current iron-smelting technology, even if the yellow powder invented, it cannot be used, because the strength and airtightness of the barrel cannot withstand the power of the yellow powder explosion.

Huang Kai was very satisfied with the power of the field cannon, and said excitedly: "Three hundred steps away can have such power, it is simply an artifact." If you increase the amount of gunpowder, you can definitely shoot through the giant shield. ”

"I'll give you an errand."

Han Zhen patted him on the shoulder.

Huang Kai hugged his fists and said, "Please ask the county magistrate to command." ”

"The best amount of gunpowder for field artillery was tested during this time."

"The last general commands!"

Huang Kai's face was full of excitement, and the whole person was ready to move.

Seeing this, Han Zhen advised: "Don't forget to add slowly on the basis of five spoons." Safety first, I don't want to see you die under the gun. ”

A trace of emotion flashed in Huang Kai's eyes, and he said solemnly: "Thank you for the county magistrate's concern, the last general will be provincial." ”

In fact, no one in the entire Qingzhou Army dared to underestimate gunpowder.

Even Liu Qi, who is not afraid of heaven and earth, is now honest after his butt was injured.

After explaining, Han Zhen took the reluctant Lao Jiu out of the barracks and returned to Shaoyang Palace.

As we are about to enter May, Han Zhang's is about to give birth.

During this time, Han Zhen stayed by her side whenever she had free time.

Dr. Zhang also came more diligently.

The two of them strolled in the backyard, and the warm sunlight shining on their bodies was particularly pleasant.

Han Zhang held his waist with one hand, and gently rested his other hand on his towering belly, and asked softly, "Erlang, the child is about to be born, have you thought of a name?" ”

Han Zhen shook his head: "I haven't thought about it yet." ”

He thought about a few, but they were all rejected.

I plan to go back and ask for the opinions of Xie Ding, Xu Cun and others, these civil officials are full of poetry and books, proficient in the three easys, and they are much more reliable than he thought.

Han Zhen asked casually: "By the way, why haven't you seen An Niang this time?" ”

Han Zhang explained: "You also know Sister Anniang's temperament, she can't be idle, and she opened a jewelry shop a few days ago. ”

"Fujin is also involved?"

Han Zhen was a little surprised.

"But I'm positive, and now I'm not naughty with them, so I'm busy with Sister Anniang early in the morning." Han Zhang pursed his lips and smiled.

Han Zhen chuckled and said, "Let her be, this girl used to be suffocated in the palace, she doesn't understand anything, it's good to experience more." ”

……

……

The Land of the North.

A team of abducted horses escorted a carriage towards the Huining Mansion in Beijing.

Entered the Huining Mansion and went straight to the palace.

In the main hall, Wanyan Wu Qimai's face was gloomy, and Wanyan Zongbi, the main battle faction of the younger generation, was even more angry.

It's just that it's too miserable to finish looking.

The limbs were broken, especially the two knees, and the bones were completely kicked and shattered by Han Zhen, and even the doctor was helpless.

The left half of his face was high and swollen, with a dark blue color, and his left eye was blood-red, and he was completely blind.

At the same time, the eardrum that was attached to the left ear was ruptured.

Most of the teeth in his mouth were gone, and he could only let out a muffled whimper.

An iron-clad Jurchen man is just scrapped.

"Was it Han Zhen who beat him?"

Wanyan Wu Qimai slowly spoke, a pair of eyes staring at the surviving envoy, his eyes flashing with bloodthirsty, like a wolf king.

Gollum!

The envoy swallowed his saliva and replied tremblingly: "Your Majesty, it was indeed Han Zhen who beat him, and Sulu accused him and was kicked to death. ”

Wanyan Wu begged to buy and asked, "Then why are you still alive?" ”

Although the tone was flat, the chill in the words made the envoy feel like falling into an ice cellar.

Lifting the wide sleeved robe and wiping the cold sweat on his forehead, the envoy stumbled and said, "Han Zhen let ...... Let Weichen bring a word to His Majesty. ”

"What?"

Wanyan Wu begged to buy interest.

"This ......"

Where did the envoy dare to say.

Seeing this, Wanyan Wu begged to soothe: "Anyway, I forgive you for your innocence." ”

After receiving the guarantee, the envoy spoke: "Han Zhen said that let His Majesty wash his neck, it won't be long before he will come to Huining Mansion in person." Pick...... Take off Your Majesty's ...... Neck on the head. ”

As soon as the words fell, the ministers in the hall were furious.

Wanyan Zongbi said in a loud voice: "I implore Your Majesty to let the ministers lead the troops south to Shandong and cut off Han Zhen's dog's head!" ”

"I'll go!"

"I'll go too!"

Wanyan Zongfu, Wanyan Zongjun and other young generations, their faces were full of anger, and they all clamored to go south.

Looking at the angry courtiers, Wanyan Wu begged to read, "Sit down." ”

He spoke, and after Yan Zongbi and the others, they had to sit down again.

Wanyan Wu begged to wave his hand indifferently: "It's just an anti-thief, why care." Does a goshawk care about the noise of a sparrow? When you go south next year, you can just destroy it. ”

Then, he looked at His Highness's envoy and ordered: "There are only Jin people who died in battle, and there are no Jin people who are still alive." ”

As soon as the words fell, the envoy's face was shocked.

was about to open his mouth to beg for mercy, but after seeing Yan Zongbi suddenly burst out, he strangled his neck.

In Wanyan Zongbi's cruel laughter, a crisp cracking sound sounded, and the envoy's head spun around.
