Mao Yuanyi smiled and said: "Xiaobao, you think too simply.
Now the emperor is building new schools in various places, which are very different from the previous private schools.
You have to learn pinyin and arithmetic in the normal school, and there are maids to teach you.
These The maids are all trained by the emperor himself, so you must not lose your etiquette."
Wang Wei clenched his little fist and said, "I don't believe it.
How difficult can pinyin and arithmetic be?
It actually requires talented women like my sister and me to learn it."
The next day, Mao Yuanyi asked to see the emperor and said that the two women were willing to enter the normal school and prepare to become the first batch of female teachers in the Ming Dynasty.
Zhu Youxiao was overjoyed and said: "Mao Qing's move is really a model for our Ming Dynasty.
I will give Mao Qing's two concubines ten pieces of silk and ten colored coins to each of them as encouragement."
Mao Yuanyi thanked him and said: "Your Majesty, I am here today because Master Bi believes that the explosive ammunition is ready for practical use.
Please come to your Majesty for inspection and guidance."
Zhu Youxiao said happily: "That's great, factory officials, please call the cabinet and let's go and see it together."
He took the five cabinet ministers to the weapons testing site of the Ordnance Bureau.
There is more than two miles of road between here and the Ordnance Bureau, connected by a cement road in the middle.
The three bosses from the Ordnance Bureau are waiting here.
Zhu Youxiao said: "Come and try it out."
Sun Yuanhua invited the emperor and ministers to the observation site, and Mao Yuanyi helped Bi Maokang conduct the final inspection.
The cannon is five hundred steps away from the observation site, and the preset impact point is also five hundred steps away from the observation site.
There are now more than twenty armored grass people and more than ten cattle and sheep staying there.
Mao Yuanyi waved a small red flag three times, and Sun Yuanhua also asked people to wave a small yellow flag three times, and then said to Zhu Youxiao: "Your Majesty, this has begun."
Zhu Youxiao nodded, Sun Yuanhua asked someone to wave the yellow flag again, and Mao Yuanyi returned the flag, only to see a burst of smoke coming out of the muzzle, and a shell flying towards the impact point.
Just when it was about to hit the ground, the shell exploded, and there was another thick smoke, and the screams of cattle and sheep came from the smoke.
After the smoke dissipated, we saw the grass people, cattle and sheep falling to the ground.
Sun Chuanting said: "Your Majesty, I would like to go and have a look."
Zhu Youxiao actually wanted to take a look, but knowing that the ministers would not allow it, he could only nodded and said, "Look carefully."
After Sun Chuanting thanked the emperor, he came to the impact point.
He opened the armor on the straw men and found that some had one layer, some had two or even three layers.
Facing the direction of the shell explosion, even the triple armor has been completely penetrated.
The cattle and sheep were even worse.
The cows were covered with dense bullet holes, and some of the sheep could not be identified as sheep at all.
He returned to the observation site and said: "Your Majesty, within thirty steps of the cannonball landing, all the first layer of armor was pierced, and the third layer of armor within ten steps was also pierced.
All the cattle beyond forty steps were killed, and the sheep were killed."
It’s beyond recognition.
This kind of shell is much more lethal than solid bullets and chain bullets.”
Zhu Youxiao nodded.
At this time, Bi Maokang stepped forward and said: "Your Majesty, I am using a delayed fuse.
The outer shell is thin and contains gunpowder and small projectiles.
When the shell hits the ground or is about to hit the ground, the fuse The gunpowder in the cannonball is ignited and the projectiles are fired out, killing a large number of enemies.
This kind of cannonball is more effective against cavalry and dense enemy troops, but it is not very effective when attacking a city. " Zhu Youxiao said: "Take a cannonball and have a look."
Mao Yuanyi came over with a cannonball and a fuse and placed them on the table at the observation location.
Zhu Youxiao saw a wooden disc behind the round cannonball and asked, "What is this?"
Bi Maokang replied: "Because the shell is relatively thin, it broke as soon as it came out of the muzzle in the previous experiment, so everyone thought of a way to install a cork disc behind the shell, so that it can be buffered and will not cause damage.
"Crack the shell."
Zhu Youxiao said: "Oh, I understand.

This disc can not only act as a buffer, but it should also make the cannonballs shoot farther."
Bi Maokang said excitedly: "Your Majesty is indeed a born sage.
I only found out after the experiment, but your Majesty can understand it just by looking at it.
You are indeed a person who knows it from birth."
Zhu Youxiao smiled and said: "This disc increases the air tightness, which will of course increase the range of the artillery shell.
Is the tube in front of it the fuse?
Let's take a look."
Mao Yuanyi took out the fuse and handed it to the emperor.
Bi Maokang said: "This is a wooden fuse.
The gunpowder inside has been tested for burning speed.
Therefore, according to the range that the artillery can reach, the corresponding length is specially made to ensure that the gunpowder in the shell will be ignited when it is about to land."
Zhu Youxiao looked at the fuse carefully, thought for a while and said: "Now there is only this kind of explosive shell, and this kind of cannon is used.
This is a twelve-pound cannon, so if we want to make a bigger cannonball, With cannons of other calibers, the length of the fuse will change, right?”
Bi Maokang replied: "That's true.
If you use a fifteen-pound cannon or even a twenty-four-pound cannon, you have to change the length of the fuse accordingly."
Zhu Youxiao added: "If the twelve-pound cannon is still used, the purpose of the shells may be different.
Some are to kill infantry or cavalry, and some are to blow up obstacles in front.
How much is the charge inside and the muzzle of the gun?
The angle will be different, and the landing time will also be different, so the fuse still needs to be changed, right?”
Bi Maokang looked at the emperor and said, "Yes, the cannonballs are different, so you can use fuzes of different lengths, and that's no problem.
It's just that the angle of the muzzle is different, and that can be changed at any time.
There's no way for the fuze to change accordingly."
Zhu Youxiao smiled and said: "So what I mean is that we make the fuze changeable at any time.
Now this fuze is ignited at one end, and the other end is used to ignite the gunpowder in the shell.
If we mark the wooden tube fuze with a scale, different shells The required distance can be calculated at different angles.
We send this standard to the soldiers.
Before firing the cannonball, the soldiers calculate the distance and punch a hole in the wooden tube at this position.
This changes the way the fuze ignites the gunpowder.
It’s time.”
Bi Maokang stared at the emperor blankly, his eyes motionless but seemingly out of focus.
Seeing this, Mao Yuanyi quietly tugged on his sleeve.
Only then did he react, and immediately knelt down in the tunnel and said: "Your Majesty, the affairs of state are handled by your ministers.
Your Majesty only needs to control the overall situation.
I dare you to ask your Majesty to stay in the Ordnance Bureau to guide my research.
Your Majesty's words , It’s better than waiting for half a year.”
Ye Xianggao hurriedly stepped forward and scolded: "Bi Maokang, have you got phlegm?
What crazy things did Sun Yuanhua say?
Why don't you ask people to take him away?"
