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

Chapter 15 The Jealous Emperor Hongwu
Cao Ying opened her eyes wide, staring at the red-eyed old man in front of her.

He was much older than he remembered.

Listening to him calling her name, Cao Ying suddenly felt her nose sore, and tears burst out of her eyes, blurring her vision!

It's been ten years!
He finally met his grandfather who loved him the most!

Those who have elderly people in their families can feel this emotion. For the elderly elders, they always affect the good memories of their childhood.

The relationship between the two will never fade away, and will only grow stronger as time goes by.

As they get older, people will miss them even more.

One day when they are gone, people finally understand that no one will ever love themselves as much as they do...

It has been a full ten years since Cao Ying left Zhu Yuanzhang's side, but now that we see him again, things have changed.

Zhu Yuanzhang's figure was no longer as tall as he remembered, and was even shorter than himself. His face was full of wrinkles, the ravines were hard to level, and it was as loose as the peel of an orange.

he is really old...

"Grandfather!"

Cao Ying rushed forward and hugged Zhu Yuanzhang, choked with sobs, and his face was already full of tears.

"Good boy... Good boy... Grandpa Huang didn't expect that you are really still alive... It's Grandpa Huang's fault. He should have sent someone to find you earlier... I have made you suffer all these years..."

Zhu Yuanzhang patted Cao Ying on the back and comforted him with a trembling voice.

Cao Ying let go of Zhu Yuanzhang, shaking his head with tears in his eyes.

"It's not the fault of Grandpa Huang. It's Ying'er who makes Grandpa Huang worried."

As he spoke, he knelt down in front of Zhu Yuanzhang with a "plop".

"Grandpa Huang, grandson is not filial! I have not been able to serve Grandpa Huang for ten years, and even my father...hasn't been able to see him for the last time..."

The usual Zhu Yuanzhang can be said to be hard-hearted, and very few people can see his tender side, especially since Zhu Biao's death.

However, upon hearing Cao Ying's words, tears welled up in his cloudy eyes.

Helping Cao Ying up, Zhu Yuanzhang said with tears in his eyes, "I don't blame you. We never blamed you. If your father knew that you were not dead, he would only be happy. How could he blame you?"

Zhu Yuanzhang and Cao Ying's grandfather and grandson cried when they met each other, but the third party, Jiang Yuke, who was standing by the side, was completely stunned, and a storm arose in his heart!
what's going on? ?

Is this young man the grandson of His Majesty the Emperor?
Is he the eldest grandson whose body disappeared back then? !

But why is he here?

What is the identity of that Cao Wei?
Since Your Majesty knows that the emperor's eldest grandson is here, why don't you accept him into the palace?

At this moment, Jiang Yu's head was full of big question marks. For a moment, he felt that his mind became a mess, and he couldn't figure out the current form.

However, there was one thing Jiang Wei knew.

Zhu Yuanzhang probably didn't disclose the news of the emperor's eldest grandson here to anyone other than him.

Zhu Yuanzhang brought him here alone to express his trust in him.

But this is not necessarily a good thing for Jiang Yu!
As a courtier, especially a spy organization like Jinyiwei, the emperor's private affairs should be known as little as possible!
Companion is like a tiger!

How did Mao Xiang, the last commander of Jinyiwei, die?

After all, they are just a knife in the emperor's hand!

In an instant, the alarm bells rang in Jiang Yu's heart, and the hairs all over his body stood on end!
Almost without hesitation, he ducked out of the door, closed the courtyard door behind him, and then turned around to look around.

Because it was close to noon at this time, there were not many pedestrians on the road, and no one noticed what happened here just now.

Jiang Wei breathed a sigh of relief, and then stood at the door obediently as a guard.

In the courtyard.

Cao Ying supported Zhu Yuanzhang and sat down under the tung tree.

Zhu Yuanzhang took Cao Ying's hand and refused to let go.

As the emperor of the Ming Dynasty, he was experienced after all, so he quickly stopped his sadness and even wiped the tears from the corners of his eyes for Cao Ying.

"Your father was buried in Dongling a few days ago. Did you go?"

Cao Ying nodded: "Of course Ying'er is going to see her father off for the last time."

Zhu Yuanzhang sighed silently: "We will take you to Dongling another day, and you can go and offer incense to your father."

Cao Ying nodded again and turned to ask Zhu Yuanzhang.

"Grandfather, please let him go, are you okay?"

Zhu Yuanzhang suddenly looked a little complicated:
"This child, Yunxi, has never had a mother by his side since he was a child. We and your father are too busy with political affairs and rarely accompany him. Later, when he grew up, he gradually discovered that he is withdrawn and doesn't like to communicate with others..."

After Cao Ying heard this, she couldn't help worrying about her own brother.

But he still cheered up and tried to put on a smiling face: "Don't worry, Grandpa Huang, when I go back, I will definitely make Yunxi get better."

"Ying'er is still as sensible as before, but you have suffered outside these years." Zhu Yuanzhang lovingly touched Cao Ying's head.

Cao Ying shook his head, "I stayed with my father, and he didn't let me suffer much. He always gave me the best..."

After a thorough conversation, the two told each other their current situation.

Zhu Yuanzhang remembered Cao Wei's Kongming lantern, so he asked Cao Ying if there was a way to solve the problem that the Kongming lantern could only go up but not down.

"Father said that the craftsman can make something, but I don't know what it is. When father comes back, Grandpa Huang, you can just ask him." When Cao Ying talked about Cao Wei, there was a touch of pride on his face, which made Zhu Yuanzhang felt a little sad.

This is his grandson, why does he seem to be closer to Cao Wei?
"By the way," Cao Ying seemed to suddenly remember something, "Grandpa Huang, please wait a moment."

After saying that, he got up and went to the house to get the gear set and pulley set that Cao Wei had made from the blacksmith.

Zhu Yuanzhang looked at the pile of iron bumps in front of him, "What is this?"

He has seen individual gears and pulleys, but what are these big and small pieces assembled together?
In fact, the appearance and application of gears and pulleys existed very early, and there are relevant records in Xia, Shang and Qin dynasties.

Guide carts, water rotary mills, and some milling machinery, or some sophisticated instruments, such as seismographs, all have the shadow of gears.

But these appliances only apply the most basic principles of gear rotation, transmission or running-in and extrusion.

The same goes for pulleys,

For example, the Han Dynasty portrait "Qin Shihuang fishing for a tripod from Surabaya" also only uses the most basic principle of a pulley that can change the direction of force.

However, the most primitive application of gears and pulleys does not save manpower, and dozens of people are required to pull a rope behind to fish a tripod.

As for the complete set of assembleable gear sets and pulley sets made by Cao Wei, it seems that there are only a few gears of different sizes and a few pulleys that can rotate, and nothing else, making people seem to have no idea that this is for making What.

"Grandpa Huang, this is the gear set and pulley set developed by my father. It can greatly save manpower!"

"Yesterday, my father and I tried it. As long as I use this gear set and pulley set, even I can easily lift a boulder weighing two to three hundred catties!"

Jiang Wei once reported this matter to Zhu Yuanzhang, and now he finally knew that it was done with the gear set and pulley set in front of him.

For a while, Zhu Yuanzhang became interested. He took the gear set and pulley set and played with them in his hands, but he didn't find anything special.

This kind of gears and pulleys can be produced in large quantities by just finding a group of blacksmiths with good skills.

He raised his eyebrows and glanced at Cao Ying.

This thing...is it really that powerful?
