Ming Dynasty: Tanks blocked the door and you said to me, "Long live Ming Dynasty"

I pulled it hard with both hands a few times, but apart from the banging sounds, there was no change at all.

The thread was too short to test its performance directly. He waved his sleeves and said, "Let's go to the Huang family's house!"

A quarter of an hour later, a wooden frame was built in the Huang family's courtyard, with a pulley hanging on the frame and a new silk thread passed through the middle.

One end of the silk thread was being held by a Jinyiwei.

The other end was tied to a sack, which was filled with thirty kilograms of stones!

"pull!"

At Zhu Youxiao's order, the Jinyiwei slowly retracted the silk thread, the pulley made a squeaking sound, and the sack was lifted up little by little.

Thirty pounds, no effort at all!

Even after adding 50 kilograms, the sack was still lifted smoothly.

The same cotton thread with a diameter of 3 mm can withstand a tensile force of 256 Newtons.

Conversion according to Newton's second law: F=ma. Usually near the surface of the earth, the value of g is about 9.8N/kg, which means that an object with a mass of 1kg is subject to a gravity of 9.8N.

From this we can calculate that the tensile force of 3 mm pure cotton thread is about 26 kg.

From this point of view, the tension of the new silk thread is on par with that of cotton thread.

"Plus!"

Zhu Youxiao continued to give orders with great anticipation.

The sack was opened and another twenty kilograms of stones were put into it.

The Jinyiwei wrapped the silk thread around his palm several times and slowly exerted force, and the sack was pulled up again.

Seventy kilograms!

This is already 1.3 times the tensile strength of cotton thread!

"Keep adding! Add it to 100 kilograms!"

Zhu Youxiao sat nearby, holding a cup of tea in his hand, his tone full of joy.

The improvement of materials is very important for the Ming Dynasty!

This time, the weavers also held their breath and looked at the Jinyiwei who was in charge of pulling the thread.

They had never tried to use the thread to pull a hundred-pound weight, and they were not sure if it could hold the weight.

The Jinyiwei loosened the silk thread, looked at his palms that had been strangled red, took out a pair of deerskin gloves from his arms and put them on.

As he gritted his teeth and exerted force, the sack shook twice, and then, as everyone expected, it left the ground!

"It's done!"

Several weavers' faces flushed with excitement. After seeing this scene, they clapped their hands and cheered each other. The flower girl from before stood among them.

It is obvious that this thread was created by them.

The corners of Zhu Youxiao's mouth also curled up slightly.

Lift 100 pounds!

Although the bowstrings of some hard bows could reach this value at this time, the production of the bowstrings was extremely complicated and could not be mass-produced at all.

But now the silk thread in the Jinyiwei's hand is different!

It was more than ten meters long and was completed in less than twenty hours.

Although it still cannot be compared with the nylon thread of later generations, it is already a rare thing in this era!

Zhu Youxiao wanted to know the limit of the silk thread, so he asked the Jinyiwei to continue putting stones into the sack.

One hundred and ten kilograms!

One hundred and twenty kilograms!

One hundred and thirty kilograms!

As he looked at the increasing weight of the sack, the smile on his face grew wider and wider.

And the weavers' faces became more and more flushed.

excited!

They have already seen that rewards are waving at them.

It was not until the weight reached 150 kilograms that a slight crackling sound was finally heard from the thread.

"boom!"

After a crackling sound, the silk thread broke on the spot, and the Jinyiwei fell to the ground with a thud.

Zhu Youxiao walked over, took the broken silk thread in his hand, and looked at the excited weavers.

"Whose idea was this? Stand out and let me see!"

The flower lady walked out amid the envious eyes of the weavers.

"I, Hua Niang, pay my respects to His Majesty!"

Zhu Youxiao looked at her in surprise: "It's you? I remember you. Tell me, how did you do this?"

"Your Majesty, I used seven kinds of materials in this thread, using deer tendons and fish skin as the bones to wrap around each other. In order to prevent rotting, I applied fish bladder glue to make it waterproof."

"The outside is then wrapped with cotton, linen and silk, and finally coated with a layer of fish bladder glue. After drying, it becomes what it is now."

As Hua Niang explained the production process of the silk thread, the smile on Zhu Youxiao's face gradually froze.

What a troublesome process!

Chapter 147: Holding something more than five meters long for self-defense?

But Hua Niang's next words dispelled Zhu Youxiao's worries.

She just winked at another weaver, and the woman went into the house and brought out a wooden frame.

The rack had two wooden wedges in the center and three on the outside.

Hua Niang pointed to the two wooden wedges in the center.

“Just attach the processed fish skin and deer sinew to the two wedges and twist the log to wrap them together.”

"Then apply fish bladder glue on it, and while it's still wet, fix the cotton thread, hemp thread and silk thread to the three wooden wedges on the outside, and turn it again to wrap it inside."

"This outer layer of weaving can not only ensure that the fish skin and deer tendons will not fall apart due to twisting, but also make the woven silk thread stronger."

Zhu Youxiao suddenly realized and a smile appeared on his face again.

He immediately pointed at the lady Hua and said, "If that's the case, you guys do it right here for me to see!"

"You are in charge of all these weavers. I want to know how much silk thread you can produce in a day!"

Hua Niang was overjoyed: "I obey your order!"

Then she began to direct the weavers to do their work.

Someone went to process the fish skin. They cut the whole piece of nitrated fish skin into narrow strips about one millimeter with a knife, and then put it on a wooden board and rubbed it vigorously with their palms.

Someone took out the processed deer tendons and pulled out extremely fine fibers from them.

Some people are also retiming cotton thread, sorting silk, and boiling fish bladder glue...

In the entire mansion, everyone except Zhu Youxiao and the Embroidered Uniform Guards started moving.

When it was time for lunch at noon, Zhu Youxiao didn't even go to the porridge stall. He stayed here and asked the Jinyiwei to get two tunas. Each person was given two pounds of meat, and they just ate them directly without even having to cut them into slices.

After dinner, Zhu Youxiao was not idle either. He drew a few pictures and handed them to Youtong.

"Go, find the best carpenter in the city and have it made according to the diagram above."

"Also, go ask Sun Kangwang if there are any lance wielders among the Jinyiwei. If not, look for them in the homes of the old military households in the city. We'll take as many as we can!"

Yutong took a look at the drawing and was a little confused, but did not dare to ask more questions.

By the evening, several hundred meters of new silk thread had been made, but without the sun, it could only be scattered around the house.

The Huang family banquet hall was completely emptied, and the silk threads were spread flat on the floor tiles. The fish bladder glue was slowly dried by the heat from the earth fire dragon.

Zhu Youxiao was very satisfied and he had already planned what to do tomorrow.

It would take at least three to five days for news to come from Zheng Zhilong. After all, the descendants of the Wang and Ximen families had moved to Ryukyu for more than two years, and it would take some time to find them.

After returning to his residence and chatting with Concubine Rong and Concubine Cheng for a while, Zhu Youxiao found that their smiles were a little strange, but he didn't take it to heart.

But when he returned to his room to sleep, he found that there was another person in the room besides Qiu'er!

Concubine Rong's personal maid, Qingyu.

He asked in surprise, "What are you doing here?"

Qingyu's pretty face instantly turned red to her ears, and she replied in a voice as soft as a mosquito: "Your Majesty, the two ladies asked me to accompany Concubine Qiu to sleep with them."

Zhu Youxiao:..........

I took a look at the bed I slept on these days and it was less than two meters wide.

Can this small bed accommodate three people?

...........

The next day, when Zhu Youxiao went out again, Concubine Rong finally smiled with satisfaction.

I got up at 10 o'clock...

Look at his steps, they seem a bit frivolous!

Sure enough, the color is like a bone-scraping steel knife!

Now, I don’t have to worry about not being able to report to the Empress when I return to Beijing!

She pulled Concubine Cheng into Zhu Youxiao's bedroom, looked at Qiu'er and Qingyu who were getting dressed and getting out of bed, and asked with a smile.

"How was it? Did Your Majesty...?"

Qingyu got out of bed, and as soon as her feet touched the ground, her brows frowned unnaturally, but she still answered immediately.

"To reply to your Majesty, His Majesty has rewarded this servant once, and Concubine Qiu has rewarded her twice."

Concubine Rong nodded with satisfaction and then sat down at the table.

Qingyu and Qiu'er put on their clothes and stood aside respectfully.

"When did your periods end for both of you?"

Qiu Er bowed and said, "To answer your Majesty's question, it was ten days ago."

Qingyu also said: "This servant was five days ago."

As a woman, and a woman who longs to conceive a dragon seed, Concubine Rong knows very well when is the best time to conceive.

She glanced at Concubine Cheng, then said to Qiu'er, "You will stay with His Majesty tonight. Starting tomorrow, you will no longer be required to sleep with him. Just lie down in bed and take care of yourself."

"Whether you will fly up to the tree and become a phoenix, or become an insignificant concubine, it all depends on your fate."

Qiu'er replied timidly, "Yes", then walked behind Concubine Cheng and stood quietly.

She was very clear about her position. At least, before she became pregnant with the dragon seed, she was still a concubine and must be a concubine.

Then Concubine Rong looked at Qingyu and said, "I will give you five days, make good use of it."

"But you must remember not to just indulge in pleasure and save His Majesty some energy. Do you understand?"

Qingyu's face was already red and she even wrote it down.

After leaving the house, Zhu Youxiao did not go to the porridge stall, but went straight to the Wen family mansion.

When he arrived, Youtong and Sun Kangwang were already waiting at the door.

On the courtyard wall next to Youtong, there were six horse lances placed diagonally, and they all looked like old items.

When Zhu Youxiao saw this thing, the corners of his mouth curled up and he gave Yu Tongyu a thumbs up.

He just mentioned it casually, but he didn't expect that this guy would actually find the thing!

This thing was popular during the Sui and Tang dynasties. Its production is extremely complicated, but its power should not be underestimated.

The tough spear handle can fight head-on with swords and knives, and the three-foot-long spear tip is a sharp weapon for penetrating armor.
