Daming: If I find a great-grandson, I will teach an emperor through the ages

Chapter 151 The power of high explosives!

Zhu Yuanzhang was about to leave when he heard Cao Wei mixing some sugar and potassium nitrate again while saying to Wang Hu next to him.

"Wang Hu, go get some gunpowder."

"promise!"

Zhu Yuanzhang immediately stopped and looked back.

Is Cao Wei going to do an explosives experiment?

He also wanted to see what kind of power this sugar and potassium nitrate had.

"Ying'er, let's go back later."

Zhu Xiongying nodded repeatedly.

Cao Wei was a little surprised, but said nothing. He had no control over what Zhu Yuanzhang wanted to do.

After a while, Wang Hu moved a wooden box filled with gunpowder.

Open the wooden box, take out a little gunpowder, and mix it with sugar and potassium nitrate.

After that, Cao Wei took out the same amount of pure gunpowder by weighing in order to make a comparison between the two.

Because Cao Wei only took a small amount, there was no need to use the shell of the shell to load the experiment.

Wang Hu once again asked Wang Hu to find some oil paper and wrap two small portions of gunpowder with different ingredients layer by layer. Finally, he tied the mouth with a rope and tightened it, leaving a fuse outside.

The overall appearance is like a small firecracker from later generations, but a little bigger.

Cao Wei and the others arrived not far outside the compound. There was an open space in front of them, and the forest in the distance had become bare due to seasonal changes.

Cao Wei took out the fire seal and stretched out his hand towards Wang Hu.

"Come on, give it to me."

After finishing speaking, Wang Hu next to him did not respond, and Cao Wei turned to look at him in confusion.

Wang Hu was seen holding two gunpowder balls wrapped in oil paper in his hands, and he shook his head slowly but firmly.

"My lord, let me do it."

Zhu Yuanzhang had just told him that Cao Wei could not be allowed to do dangerous things, so he naturally had to fulfill his duties.

Cao Wei chuckled lightly and handed him the fire seal in his hand.

The gunpowder mass he made this time did not contain too much gunpowder and was basically not dangerous.

Wang Hu placed the gunpowder ball on the ground, took the gunpowder stick, and then asked Cao Wei for instructions.

"Sir, which one should I try first?"

"The one full of gunpowder, remember to throw it far away after lighting it," Cao Wei replied.

Wang Hu nodded, and then picked up the gunpowder ball on the right, which did not contain sugar or potassium nitrate.

Without any more nonsense, Wang Hu directly lit the fuse on the gunpowder ball, and then threw it away from a distance with all his strength.

In order to ensure safety, Cao Wei left the length of the fuse a little longer. The gunpowder ball was thrown by Wang Hu. After it landed far away, the fuse had not yet burned out.

It took two or three breaths and after the fuse burned out, the gunpowder ball was ignited and exploded!

"Bang!!"

The moment Cao Wei saw the gunpowder ball explode, a flash of fire appeared, and almost at the same time, a huge explosion sounded!
The ground around the gunpowder ball was kicked up with a burst of dust, and even pieces of soil were lifted up.

Wang Hu looked at Cao Wei, who nodded silently.

"Try another one, throw it in a different spot."

"promise!"

Wang Hu received the order, turned his body, picked up another gunpowder ball, lit it with a fire stick, and threw it out again.

Cao Wei's eyes widened and he stared in the direction of the gunpowder ball without blinking.

The same was true for Zhu Yuanzhang and Zhu Xiongying, their eyes widened as if they didn't dare to blink.

at last,

The fuse of the gunpowder ball was ignited, and everyone saw the fire flash out again, and an even bigger explosion sounded!
"Bang!!!"

There was another burst of dust flying, and everyone could even see the dust being scattered around by the air fluctuations of the explosion, and even more pieces of soil were thrown away by the explosion.

Judging from the sound of the explosion and the movement it made, it was obviously a gunpowder mass added with sugar and potassium nitrate, making it even more powerful!
"Come on, let's go and see."

Cao Wei said something and took the lead in walking forward.

Zhu Yuanzhang and Zhu Xiongying quickly followed, and finally followed Wang Hu.

Several people first came to the site where the first gunpowder mass exploded, and saw a small pit on the ground. The soil inside was blown to pieces, and there were traces of black gunpowder explosion around it.

Everyone has seen this kind of gunpowder explosion, so it's not too unusual.

Then, several people turned around and came to the location where the second gunpowder mass exploded.

Seeing the pit created by the explosion on the ground, Zhu Yuanzhang couldn't help but be speechless!
Compared with the small pit just now, this pit is obviously a whole circle bigger!
Moreover, there were very few pieces of soil in the pit, but they were all scattered around the pit!

This will only happen if the explosion is powerful enough!
The increased power of the explosive mixed with sugar and potassium nitrate can be seen from this!
This was just a small ball of explosives wrapped in oil paper by Cao Wei, but the power of the explosion was so much increased.

If cannonballs are actually produced, and the mixing amount of sugar and potassium nitrate is increased according to the amount, the power of the explosion will be increased to a very terrifying level!

"Ha ha ha ha……"

Zhu Yuanzhang burst out laughing when he saw this scene.

With such terrifying explosives, and when Cao Wei successfully improves the artillery, which country can withstand such a powerful artillery strike?
From then on, Ming Dynasty was truly not afraid of foreign enemies!

I can go, but the bandits can't invade!

"Cao Wei, according to your estimate, how long will it take for this artillery improvement to be completely completed?" Zhu Yuanzhang looked at Cao Wei with warm eyes.

Cao Wei thought for a while and said:

"Gunpowder has been successfully developed, and then mass production is not difficult. The production of new artillery barrels should not be too difficult. Only... the triggering detonator of new artillery shells is a bit difficult. I am afraid it will take a few more experiments, but three One month should be enough."

After hearing this, Zhu Yuanzhang nodded with satisfaction.

Three months, which was much faster than he expected.

"Okay! Okay! Okay!" Zhu Yuanzhang said hello three times in a row.
"The gold mines in the Japanese country have never been able to send people to occupy them. When you develop new artillery, it will be time for the gold mines in the Japanese country to belong to our Ming Dynasty, hahahaha..."

When Zhu Yuanzhang left, the sky was gradually darkening.

Cao Wei's busy day is over.

The new idea of ​​​​artillery is feasible, and then just follow the plan step by step.

After Wang Hu packed up the things in the courtyard, Cao Wei asked him to go back and rest.

It's almost time for the manufacturing bureau to stop work and eat.

Afterwards, Cao Wei hummed a little tune and hurried back to Cao's Mansion... On the other side,
Zhu Yuanzhang and Zhu Xiongying were sitting in a carriage and heading towards the palace.

Zhu Yuanzhang also closed his eyes, shook his head and hummed an unknown emphasis.

"Grandpa Huang went out to relax today. It seems to have a good effect." Zhu Xiongying said with a smile.

Zhu Yuanzhang opened his eyes, nodded, and sighed happily.

"Cao Wei is really our lucky star!"

"Not only did you return Ying'er to us, but you also did so many things for Ming Dynasty. We will remember them one by one."

"Now that the artillery is improved, it can be said that the Ming Dynasty no longer has to worry about foreign enemies. When the historian writes down this note, Cao Weizu will be famous throughout the ages!"

"This boy is really good!" Zhu Yuanzhang said with a smile.

Zhu Xiongying could see that Zhu Yuanzhang was very fond of Cao Wei now and was very happy.

I think the two of them were not as harmonious as they are today...

"It's just..." As he said that, Zhu Yuanzhang frowned again.

"What's wrong, Grandpa Huang?" Zhu Xiongying asked.

"Cao Wei, this kid, has made great contributions one after another. Each one is bigger than the last. This time he improved the artillery. We can also give him a promotion. Ranking among the three princes is not a problem. The problem is that if he makes meritorious service in the future, we will have nothing to reward him. .”

Cao Wei is now a Dazhu Kingdom, and there are only three princes left who can be granted titles. From now on, there will really be no titles left.

You can't make him emperor or prince.

The main reason is that Zhu Yuanzhang now values ​​Cao Wei too much and regards him as his junior. He doesn't want to see him pay in vain without getting the reward he deserves.

What if someone else has made a great contribution and cannot be rewarded?Give a verbal reward.

"Your Majesty, you are worrying too much. All Mr. Zhong Guogong has always done is to serve the country without asking for anything in return. I believe that Mr. Zhong Guogong doesn't care too much about rewards."

"Besides, Grandpa Huang now wants to marry Aunt Hanming to Duke Zhong Guo, so he and we are part of the same family, and the family doesn't have to be so alienated."

After Zhu Yuanzhang heard this, he nodded slowly.

Indeed, Zhu Xiongying is right.

Cao Wei has done so many things and made many contributions, but he has never actively asked for rewards. He has always sought benefits for the craftsmen and the common people.

"Well...after Cao Wei completes the improvement of the artillery, we will choose a day for him to marry Hanming."

The intelligence displayed by Cao Wei makes people unable to see the end, and even makes Zhu Yuanzhang wonder whether Cao Wei can fully utilize what he knows in his life.

Originally, Cao Wei wanted to pass on his knowledge to Zhu Xiongying, but now that Zhu Xiongying has returned to the palace, political affairs have become his main responsibility, and he has no extra energy to learn Cao Wei's scientific research knowledge.

But the scientific research knowledge in Cao Wei's mind is extremely valuable and must be passed down.

Zhu Yuanzhang was worried about asking Cao Wei to find someone else to teach him. If one person failed to do it properly, there would be unprecedented turmoil in the Ming Dynasty.

For example, if Cao Wei intends to rebel, with his ability, as long as he gets a little chance, it is really possible to overthrow the entire Ming Dynasty.

If these weapons, such as continuous muskets and powerful artillery, were used to attack himself, Zhu Yuanzhang would not know how to win.

It's just that what Cao Wei did was bound to make the Ming Dynasty miserable again. However, Cao Wei was kind-hearted, cared about the people of his family and country, and chose to serve the country wholeheartedly.

This is also the reason why Zhu Yuanzhang pays more and more attention to Cao Wei. As an emperor, he now completely regards Cao Wei as his descendant.

Therefore, Zhu Yuanzhang betrothed his daughter Zhu Hanming to Cao Wei.

On the one hand, it is indeed because Zhu Yuanzhang loves Cao Wei, a younger generation, and wants to solve life-long affairs for him.

On the other hand, when the two give birth to children, Cao Wei will teach his knowledge to future generations. In this way, the Cao family and the Zhu family will become one family, close to each other. Cao Wei's knowledge will be safe enough, and the Cao family will be noble and prominent for generations to come. People can excel.

This year is already the end of the 28th year of Hongwu. Zhu Yuanzhang will be 69 years old after this year. He has noticed that his body is beginning to decline and he may not be able to survive for a few more years.

After arranging all this, he can leave with peace of mind.

Zhu Xiongying, Cao Wei, they all need to be well...

"After Cao Wei and Ming'er get married, it's time to discuss the marriage between Ying'er and the daughter of the Xu family. Before we leave, we also want to see our great-grandson." Zhu Yuanzhang said here He laughed, his face full of wrinkles.

Zhu Xiongying took Zhu Yuanzhang's hand,
"What did the emperor say? With such a strong body, the emperor will definitely live a long life."

"Hehehehe," the wrinkles on Zhu Yuanzhang's face became deeper.

"Cao Wei is busy improving artillery every day and has no time to go to the palace to see Hanming. Let's talk to her when we get back and ask her to make more trips to the Cao Mansion..."

Zhu Xiongying nodded.

Grandpa Huang is also a little anxious...

A month passed,
The craftsmen of the Manufacturing Bureau successfully manufactured a rifled artillery piece.

All that remains is the development of new artillery shells.

The shell design of the cannonball is not satisfactory, as long as the size of the barrel is adjusted to make a shape suitable for firing.

But the difficult part is how to install the primer detonator on the head of the projectile.

The primer of the musket has a firing pin that can trigger it accurately. If the primer of the musket is directly applied to the shell, it will be difficult to trigger it accurately because of its extremely small size.

Cao Wei couldn't find a good way for a while, so he could only put it aside for the time being and report the news of the successful development of the artillery to Zhu Yuanzhang.

When Cao Wei returned to Cao Mansion that day, he saw an unexpected person.

Zhu Hanming didn't know when he arrived at the mansion, and he had even prepared the food.

Cao Wei couldn't help being a little stunned when he saw this scene.
"Princess? What are you..."

Zhu Hanming forced himself to calm down and replied:
"Zhong Guogong is busy improving artillery every day and is tired from working in the manufacturing bureau. Hanming has nothing to do, so he just wants to cook some meals for Zhong Guogong. It's just that Hanming doesn't have time to learn how to cook. If his taste doesn't suit his taste, I hope Zhong Guogong doesn't want to do it. dislike."

Cao Wei looked at the table in the room. There was a lot of food on it, and it looked pretty good.

A month ago, Zhu Yuanzhang told Zhu Hanming that he should go to Cao Mansion more often. Anyway, the two of them would get married sooner or later, so there was no need to be too rigid.

After Zhu Hanming returned, he asked his mother, Concubine Han, who also agreed.

However, it was inappropriate for Zhu Hanming to only go to Cao Mansion to meet Cao Wei, so Concubine Han asked Zhu Hanming to learn cooking skills. Even if he cooked a meal for Cao Wei, he would be regarded as a famous teacher.

Cao Wei raised the corners of his mouth, came to the dining table, and took a closer look.

There are chicken, duck and fish, and the meat and vegetables are combined. It can be seen that Zhu Hanming cooks it very carefully.

"Since it is the princess's craftsmanship, I have to give it a try."

Cao Wei was about to take off his chopsticks when he looked at Zhu Hanming again, "Princess, please sit down and eat together. The princess has come here to cook. How can I enjoy it alone?"

After hearing this, Zhu Hanming slowly came to the dining table and sat down.

Cao Wei picked up his chopsticks, took a bite of the roast chicken, nodded immediately, and tasted other dishes. They all tasted great.

"I didn't expect that the princess's craftsmanship is so good." Cao Wei praised sincerely.

"Mr. Zhong Guogong deserves the award." Zhu Hanming responded.
