Ammonium nitrate is a solid chemical material, colorless and odorless, with white transparent crystals.

In addition to being able to make fertilizer, it is also a more powerful explosive than black powder.

Due to the low cost, the fertilizer of the last century was produced from this thing.

It's just that this thing reacts when it encounters heat or collision.

In addition, the illiteracy rate was high at that time, and even though the bags were written with warnings prohibiting fire roasting and beating, there were many accidents.

Ammonium nitrate fertilizer will agglomerate when it encounters moisture, and the common people are less literate and do not understand any chemical principles.

It is customary to roast it over fire or hit it with a hammer.

And then.

Rumble!

So since the beginning of the '00s, this thing has been listed as a prohibited sale.

Touching his chin and excitedly thinking about his few memories, Zhu Zhangui was very excited.

Although he has used various methods to improve Daming's black powder to the extreme, the power of black powder is a little worse after all.

If nothing else, let's just say that the earth-shattering thunder thrown by the soldiers, that thing is like a small watermelon, ordinary people don't throw it far at all, and the explosion power is average.

If the iron shell is not made well, it will be almost two or three halves after the explosion.

Not to mention killing the enemy, at most scare the enemy.

Therefore, it is imperative to replace black powder with a new gunpowder, or to increase the power of black powder.

But Zhu Zhangui didn't study chemistry, in addition to knowing one nitrate, two carbons, three sulfur, he also knew that adding some sugar to it would make a big Yin Wan.

But the problem is that there is no white sugar in his supermarket, and he only knows a little about the method of filtering brown sugar.

He told the artisan battalion that he didn't know much about it, but he hadn't studied it yet.

Although the new school has chemistry, it has only just been popularized, and it has not been effective at all in a few years.

Zhu Zhangui himself doesn't like to learn, and some of his subordinates are people who learn, so he is too lazy to learn.

It may take a while for a new learner, and the supermarket can't draw it, and I'm too lazy to learn.

Just when Zhu Zhangui thought that he might have to use black powder for a while, the supermarket god finally showed his might again.

"Husband!"

Zhu Zhangui suddenly went crazy and yelled, startling Zhao Ling'er, and hurriedly reached out and pulled Zhu Zhangui's clothes to calm him down.

Zhu Zhangui, who was called back to God by his daughter-in-law, looked at the people who looked at him suspiciously, and smiled apologetically.

"I'm sorry everyone, I just remembered some things, and I ask for your forgiveness if you are a little excited!"

"It's okay, it's okay..."

Everyone hurriedly shook their heads.

You're a grandson, don't say yelling, dancing bare-ass, we don't dare to blame you.

The old man raised his eyebrows thoughtfully.

"Something new!"

Zhu Zhangui gave a confirmed look back.

The old man understands in seconds.

Smile to everyone.

"The child may still be thinking about government affairs, and he is distracted for a while, disturbing everyone's interest, come and come, everyone continues to drink!"

Everyone didn't even dare to say it, raised their glasses and continued to drink with the old man.

Thinking of the usefulness of the item, Zhu Zhangui couldn't sit still.

Several times when someone toasted him, he was in a trance.

I kept thinking about how powerful ammonium nitrate mixed with black powder would be?

The old man who noticed this scene understood that Zhu Zhangui might have something important to do, so he waved his hand at Zhu Zhangui.

"Okay, you little cub, people are not here, if there is anything to do, hurry up and get busy!"

"Yes!"

Zhu Zhangui made a salute and explained to his daughter-in-law, and then left the venue with Hu Yu and the others.

"Go and call Master Zhang and them!"

On this expedition, he took ten craftsmen with him.

The main task was to repair flintlock pistols or prepare gunpowder for soldiers in front.

The navy is a big eater of gunpowder, and every battle is measured in kilograms.

On the sea, due to the heavy turbulence of the ship, the black powder is well equipped, and if it is not stored properly, it is easy to have an accident or get damp.

Therefore, most of the gunpowder used by the navy, except for the storage of the needs of two wars, was allocated when it was idle.

Soon several old craftsmen were called to a clearing.

"Your Highness, what do you command!"

Zhu Zhangui pointed to a white bag and a barrel of gunpowder at his feet.

"Master Zhang, this is a new gunpowder additive, you and black powder according to the ratio of 1:1 to prepare a barrel out, remember not to hit hard in case of fire, otherwise..."

Zhu made an explosive gesture.

Craftsman Zhang's face changed, and he understood the instability and danger of this new thing.

Take a deep breath and nod slightly.

"Your Highness, you take people away from me, and then hand it over to the old man."

Zhu Zhangui patted the old craftsman on the shoulder and left a hundred meters away with Hu Yu and the others.

Only Master Zhang and a few of his apprentices were left in place.

After running a hundred meters, Zhu Zhangui hesitated for a moment and ran out a little more with someone.

Ammonium nitrate explosives, he was still the first to see.

He had prepared 50 catties of ammonium nitrate and 50 catties of granular black powder, and he knew how powerful this thing was, so it was better to stay away and rest assured.

"Go to the banquet and tell them that if there is any movement later, don't panic, tell them that I am testing new gunpowder!"

Worried that the big explosion would cause panic later, Zhu Zhangui asked people to notify the banquet hall.

After Zhu Zhangui was far away, Master Zhang took two apprentices with wet towels on their faces and began to get busy.

He took a large wooden barrel, then took two wooden spoons of the same capacity, and began to pour a spoonful of black powder and a spoonful of ammonium nitrate into the barrel.

While Master Zhang and his eldest apprentice were pouring things inside, the second apprentice on the side was holding a small wooden fork and stirring the two things evenly.

After half an hour of busy work, a barrel of mixed black powder ammonium nitrate explosives was officially formed.

Taking off the face towel on his face and wiping the cold sweat on his head, Master Zhang gestured into the distance.

Soon a soldier ran over with a bundle of leads.

Carefully closing the top of the barrel, Master Zhang took out a lead and poked it into the lead opening that had been set aside in advance.

After confirming that everything was ready, Master Zhang asked the soldier with a flashlight next to him to say hello to the distance.

The soldier picked up the flashlight and shook it at Zhu Zhangui.

Zhu Zhangui, who had been staring at Master Zhang's side, asked the soldiers behind him to go to the banquet hall again to inform him after receiving the signal, and then gave a signal to Master Zhang's side.

Then Zhu Zhangui squatted on the ground with the people around him, stretched out his hand to block his ears and opened his mouth wide, looking at Master Zhang.

After receiving the signal of ignition, Master Zhang asked the apprentice to run first, and then a soldier lit it with a flashlight, took out the fire fold and lit the fuse, and the two ran away.

"Whoa..."

The lead burned slowly, and when Master Zhang and the others ran to Zhu Zhangui's side, it slowly burned to the barrel.

A group of people squatted on the ground like toads, no one spoke, all of them were like Zhu Zhangui, stretching their necks and looking in the direction of the barrel.

Although the darkness obscured their vision, they all knew in their hearts that a huge explosion would appear from there later.

After receiving the signal, the banquet hall also stopped the noise, blocked their ears as requested, and looked at the place where the explosion was about to rise.

"Poof..."

The last bit of fuse rushed into the barrel, and the spark ignited the granular black powder, which burned violently, causing the mixed ammonium nitrate to react violently.

"Boom Boom..."

An earth-shattering loud bang sounded, and in the huge firelight, a small mushroom cloud rose into the sky.

The powerful explosive energy enveloped the sand particles on the beach, forming a circular shockwave that slammed away in all directions.

"it!"

Zhu Zhangui, who was squatting one or two hundred meters away, was staggered by the powerful air waves, and the sand particles carried by the air waves covered his head and face.

Zhu Zhangui, who was squatting on the ground, shook in front of his eyes for a while, and his ears were buzzing.

Originally, he had already set the ammonium nitrate black powder very high in his heart, but now it seems that it is still low.

The explosive power of this thing in a closed situation is at least 2~3 times that of black powder, or even more than four or five times.

"It's so powerful."

quickly came to the explosion point, looking at the huge crater, Zhu Zhangui's eyes lit up.

If this thing were to be put on the Celestial Arrow, the enemy would be very sour.

"Master Zhang, we have a few Heavenly God Arrows here."

"5 roots!"

Master Zhang, who was also shocked by the powerful explosive power of this gunpowder, was stunned for a moment before reporting the number of Heavenly Arrows.

"Good!"

Zhu Zhangui clapped his hands with satisfaction, and explained to Master Zhang: "I will prepare 2,000 catties of new materials for you, and you will find a way to change the gunpowder inside." ”

"By the way, you study the power of new materials and oil, and pay attention to safety during the test, but don't do it on the ship, if there is an accident, the ship may be blown up."

The New Year of Yongle 13 years was spent in a huge explosion.

On the fourth day of the first lunar month, after leaving the troops to guard the base, the Ming Overseas Expeditionary Force, under the leadership of Zhu Zhangui and Zhang Fu, marched like a military exercise.

"Your Highness, the ministers are always up and down in their hearts, and they always feel that the surrender of this Syed Dynasty is a bit unreliable!"

On the huge command battleship, Zhang Fu stood behind Zhu Zhangui, looked at the fleet slowly moving on the sea, and expressed the doubts in his heart for a long time.

Originally, he wanted to tell the old man this, yes, but he was afraid of ruining the old man's interest.

Zhu Zhangui has been busy a few days ago, and he didn't even have a chance to meet, he just couldn't say anything if he wanted to.

Today, when he got on the boat, he spoke out the doubts in his heart.

Zhu Zhangui, who was holding a telescope to observe the sea, glanced back at him and said with a smile, "There is no problem, that's fake!" ”

Zhang Fu was in good spirits.

"Your Highness, did you find anything?"

Retracting the binoculars, Zhu Zhangui nodded slightly.

"I sent a group of sentries before the New Year, and they came back two days ago!"

"According to their inquiry, there was a coup d'état in the Saeed dynasty a few days ago, Hazr Khan, who had a good impression of us, died, and his eldest son became the new king!"

As he spoke, Zhu Zhangui's eyes narrowed slightly: "This eldest prince is a ruthless man, not only cut his father with his own hands, but also killed his mother, his brothers and sisters, including the concubine that Master Yang found for me, were all killed by him!" ”

Zhang Fu looked at Zhu Zhangui expectantly.

"Your Highness, in this case, they are ready to fight us."

Zhu Zhangui bowed slightly.

Turning around and walking to the command room, Zhu Zhangui took Zhang Fu to the side of the map and pointed to the location of the exercise.

"This is a triangular terrain, and they have buried nearly 100,000 soldiers and horses in these three locations!" Pointing to the location of the other party's ambush soldiers and horses, Zhu Zhangui continued to Zhang Fu:

"Their men should have entered the position by now, just waiting for us to take the bait!"

Looking at the map, Zhang Fu quickly planned the battle strategy in his heart.

"Our initial plan for the exercise was to land the army, but in this case we fell into the trap of the enemy, even though we were well prepared, but we were still in a weak position under the enemy's leisurely work!"

"If the other side chooses to attack when our troops are halfway off the ship, then not only our army will be in danger, but the navy will also be in danger!"

Looking up at Zhu Zhangui, Zhang Fu proposed: "Your Highness, the minister's idea is that the army will land in concealment dozens of miles away, and the navy will continue to move forward. ”

Stretching out his hand and pointing to the place in the triangular sea.

"Although the sea area here is not large, it is still no problem for our warships to move!"

"As long as our navy does not dock, it is impossible for the other side to attack us."

"So the minister guesses that they may block the entrance to the sea and besiege us!"

Zhu Zhangui nodded in confirmation, and continued Zhang Fu's words.

"But it's different if the army lands early, there is our navy shelling in the triangle and the army attacking outside."

Zhu Zhangui slammed his fist on the map.

"Under the attack of the two, they will definitely lose!"

The battle plan was thus decided.

On the 14th day of the first month of the 14th year of Yongle, the temporary wharf of the military exercise.

The eldest prince, who ascended the throne as the new king, stood on the dock with several important ministers, nervously looking at the empty sea in the distance.

"Didn't you say it's here today, why haven't you come yet? Did they find something? ”

Looking at the empty sea, the eldest prince became nervous.

The Secretary of State next to him smiled confidently.

"Your Majesty, don't worry, our plan is foolproof, the reason why they haven't come until now may be that something happened on the road and delayed for a while!"

The eldest prince hesitated, but still asked uneasily.

"How are the soldiers preparing, are they well hidden?"

The Minister of State, who was a little annoyed by the question, forcibly suppressed the unhappiness in his heart.

"Don't worry, Your Majesty, the soldiers are very well hidden, they won't find out."

"When the time comes, when their army lands, the generals will attack."

"With or without intention, we will definitely win this war!"

"Your Majesty, a ship is coming!"

Just as the eldest prince was about to ask, the lookout post on the high place reported the news that a ship was coming.

The people waiting on the shore were shocked and looked at the sea.

Soon. A group of black dots appeared on the surface of the sea in the distance.

The enemy is coming.

Not to mention the eldest prince at this moment, even the originally determined Minister of State's heart became nervous.

Can the Sayyid dynasty rise?

It's up to this shudder.

On the flagship warship, Zhu Zhangui looked at the dock with a telescope in his hand, and asked Yang Pu, who was also holding a telescope beside him.

"Master Yang, are they all there?"

Yang Pu observed the people on the dock and replied after confirming that they were all familiar faces.

"That's right, everyone is here, except for Hazr Khan."

After confirming that it was these people, Yang Pu put down the binoculars and hesitated and asked.

"Your Highness, is your information really accurate, and is there any misunderstanding in this?"

Zhu Zhangui waved his hand to Li Hu behind him.

"Misunderstanding is misunderstanding, as the boss, can't you teach the younger brother a lesson!"

"Correct him when he is wrong, and let him remember it for a long time when he is wrong."

Yang Pu: The people of the old Zhu family really don't have a good thing.

The fleet slowly unfolded.

In the cabin, an artilleryman quickly loaded the ammunition, and the gunners were estimating the distance between the ship and the coast, adjusting the angle of the gun at any time.

In the power cabin, a sailor clutches the oars, ready to speed up or retreat at any time.

"Your Highness, I've got something!"

When there were still several nautical miles from the coast, Master Zhang and dozens of soldiers, carrying a huge object, came to the launch location.

Zhu Zhangui, who had been observing the shore, stretched out his hand and pointed in the direction of the pier.

"Aim for me, and you'll be the first shot to start this war!"

"Yes!"

Master Zhang, who participated in the war for the first time, responded excitedly and hurriedly beckoned the soldiers and apprentices to quickly put up the shelves.

Because the tail flame of the god arrow is too strong, and the ships of the Ming Dynasty are all made of wood, so when this thing is launched on the ship, it needs to be adjusted to prevent the burning tail flame from igniting the ship.

This is a new generation of Celestial Arrows.

Unlike the old version, the new version not only has a rear wing, but also has a smoother shape.

In many tests, the veteran craftsmen were able to ensure accuracy, and the deviation did not exceed 50 meters within three miles.

As for three miles away, only God knows where to fly.

Don't underestimate the accuracy of these three miles, for this accuracy, Zhu Zhangui threw millions of taels of silver into it to achieve this result.

Master Zhang took a few craftsmen to climb on the launch frame and study for a long time, and finally determined the launch angle after constantly adjusting the angle.

Zhu Zhangui picked up the walkie-talkie and dialed Zhang Fu's channel.

"Land Tiger, Land Tiger, this is the Divine Dragon, have you arrived at the designated position for combat!"

The walkie-talkie was silent for a while before Zhang Fu's voice sounded from the other side.

"Land Tigers received, we have now arrived at the designated position, we are in formation, ready to attack at any time!"

"Good!"

Zhu Zhangui nodded with satisfaction.

Then he observed the situation of each battleship, and after making sure that the battle flags that had been prepared were hung on the bow of the ship, he stretched out his hand to Master Zhang and Zhang Fu in the walkie-talkie and ordered.

"I... Zhu Zhangui, the grandson of Emperor Daming, officially ordered to start a war against the Saided Dynasty! ”
