Gu Jiao went to the hospital.

Today is the date of return visit agreed with the mysterious figure, who is waiting in the rejuvenation hall early.

This time, he didn't ask people to clear the hospital.

Gu Jiao, who was a little late to see off Xiao LIULANG, told her to wait for a while.

The face of the young guard beside him was completely black: "hum, you are the first one who dares to let my master wait!"

Gu Jiao shows her hand: "Oh, it's a great honor."

The young guard turned his face.

Gu Jiao enters the wing room.

The man was wearing a hat with a veil, which covered his face, but his noble demeanor could not be covered.

He was still surrounded by two gentle servants.

After seeing Gu Jiao several times, people were used to Gu Jiao's rudeness. When Gu Jiao saw that her father didn't even have a gift, she just sat down. She could only complain in her heart, but she didn't dare to satirize.

There's no reason for him. My father's illness is cured by this little girl!

Gu Jiao gave him three injections of benzathine penicillin every seven days. The last one was given last month. Today, he came here for a review.

Gu Jiao gave him a pulse and made an examination.

"Am I cured?" There was joy in the man's voice.

Gu Jiao took off her gloves and said to him: "at present, it seems that the recovery is good, but it will take two years to be completely cured without recurrence. It is not suitable to follow up."

"Er..." the man was silent.

Gu Jiao noticed that his mood was not the same as a few days ago: "what's the matter? Can't follow up? "

The man laughed and said, "to be honest, I'm leaving."

"Oh." Gu Jiao is not surprised. His accent is not like that of a local. He may not even be from Youzhou. Gu Jiao can't guess where he came from.

The man said with a kind face: "but I believe I have been cured by the girl. I venture to ask the girl, you are so skillful in medicine that I don't know where to learn from."

Gu Jiao said: "I have many teachers."

This is the truth. In her previous life, she studied medicine in University and graduate school, and then went to graduate school. There were many teachers who taught her.

The man is not a person with no eyesight. Gu Jiao doesn't want to talk more about this topic, so he doesn't ask any more questions. He said: "thank you for curing my illness. I have one more thing to do today, which is to say thanks to the girl solemnly."

"You've already paid the consultation fee, so you don't have to thank me..." Gu Jiao said half way, and saw the man take a brocade box from the servant's hand and put it on the table.

The brocade box is not common at first sight.

Gu Jiao seamless switch: "thank you, if you really want to send, I can only reluctantly accept."

The next people simply did not see, you, you have the ability to have more backbone ah, continue to say you do not ah!

The man grinned and pushed the brocade box to Gu Jiao's hand.

Gu Jiao opened it and saw that it was an exquisite jade folding fan. Gu Jiao held the fan in her hand. It felt cool and the grease was clear. It was really a good fan.

"Do you like it?" Asked the man.

Gu Jiao hesitated.

People are silly, aren't they? They don't like fans made of Millennium cold jade?

"If you don't like it, you can change it for something else." The man said gently.

"Well, is there a fan made of gold?" Gu Jiao asked.

The next people all shook their bodies twice. You really don't know how to be polite. You have to exchange gold when you come up, but is gold valuable? Country people just don't know!

The man laughed and said, "there is no gold fan, but I have other gold things here."

After that, he called one of the servants and whispered two orders in his ear. His eyes were straight: "is this not right, sir? That's... "

The man didn't have such a good face to Gu Jiao: "let you take it, what do you do with so much nonsense? Next time I went to Jiangnan, I found that you have more and more other skills. "

"Yes." The servant did not dare to neglect. He gave Gu Jiao a look and went to the carriage to get a new box.

It was made of pure gold.

Huarong Road is a kind of ancient educational toy. It's sold in many shops, but it's made of wood. Gu Jiaotou saw it once.

It's fun and it can shine. I'm sure the small clearance will like it.

Gu Jiao nodded with satisfaction.

The man looked at her unsmiling face and finally had a small expression. He couldn't help laughing and said, "does the girl like gold or Huarong Road?"

Gu Jiao said: "not me, but my brother."

The man smile: "the girl has a younger brother?"

Gu Jiao compared her fingers: "not one, but three."

Man: it doesn't look good to give one away!

The man also gave Gu Jiao two gifts, and the next people all felt their own master's pain. Why don't you say that? Does this kill chatting? You're killing yourself?

There is no place to say.

It's your own face.

When Gu Jiao left the hospital, there were three more luxury gift bags in the small basket!

The man arched his hand at the gate of the rejuvenation Hall: "girl, see you later."

Gu Jiao glanced at him: "see you later with the doctor. What's wrong with you?"

Then she went into the crowd without looking back, carrying a small basket.

He was so angry that he gritted his teeth and said, "look at her..."

The man was also a little stunned. After all, no one dared to talk to him like this for many years, but he would smile happily after passing by: "yes, what's wrong with me? Why do you want to see a doctor? Isn't it good to be healthy? "

"My lord..."

"It's time to go back to Beijing. Let's go."

--

Gu Jiao left the rejuvenation hall and left for the only iron shop in the town.

This iron shop has been open for more than 20 years, so it is an old shop.

As soon as Gu Jiao came to the door, she heard the sound of hammering. The business of the iron shop was very good, and the blacksmiths were very busy.

There was no counter in the shop. Gu Jiao called a man and asked, "I ordered iron fittings here last month. Today is the delivery day."

The man carried a basket of heavy iron ore and yelled at the lobby: "Lao Wang! Someone's coming to get the goods! "

"It's coming, it's coming!" A sweating blacksmith came out in a hurry. A towel was hanging around his neck. As he wiped the sweat on his face, he looked at Gu Jiao and said, "who wants to take the goods? Do you like it? "

The last time the old fellow of the Hui Chun shop ordered the goods, the old blacksmith did not know her.

Gu Jiao gave a hum and handed him the card.

In ancient times, there were few scholars and few blacksmiths could read, so they all used pairs of cards. Each pair of cards had a corresponding row number. According to the row number, we could know which batch of goods it was.

"You haven't finished this." The old fellow Smith frowned.

Gu Jiao said: "but last time I said I would take the goods today."

The old fellow smugly his sweat with a towel, and said, "but we really didn't finish it, and we couldn't help it."

"About how long?" Gu Jiao asked.

"This..." old fellow Smith thought, "one or two months."

Gu Jiao doubts: "so long? I don't want too many farm tools, do I? "

"Old fellow Smith said," it's not your job. It's a job in the shop last month. Before you get it, we need to exploit one thousand iron pieces of iron ore. Where can we get this small iron shop? It's more than half way off now! We don't have enough hands, we don't have enough stoves... "

"Lao Wang! It's time to strike iron! " A blacksmith inside yelled.

"Ah! Here we are The old fellow Smith shouted at the shop and turned to Gu Jiao. "Girl, you can see it again next month."

Gu Jiao didn't want to wait that long.

When the old fellow scorched by the flames, she entered the iron shop, and the men and the blacksmiths were all in a hurry. Nobody noticed a little girl.

To be fair, there are not many people in the iron shop. According to this number, it's only right to make 1000 iron wares a month.

Then the problem should not be the shortage of manpower.

Gu Jiao looked at their blast furnace again and found out the problem at once.

Ironmaking needs a very high temperature, in order to reach this temperature, blast furnace will generally use blowing equipment. Gu Jiao originally thought that the iron shop of this dynasty also used the water exhaust blast, but unexpectedly it was the most primitive human blast.

The biggest disadvantage of manual air blowing, commonly known as renpai, is that there is only one Tu (a bag made of horse skin) in one interface. Once the manual air blowing is done, the Tu is closed once.

In other words, a blast furnace can blow up to six times at the same time.

It's much less efficient than water drainage.

The water discharge is driven by hydraulic power, and the water discharge can be closed several times every time the water turbine rotates, which not only saves time, but also saves manpower.

Gu Jiao spoke to the old fellow Smith.

The old fellow was surprised. How could a little girl in a uniform know all this?

After being surprised, he said, "I've seen the one you said. Only the iron shop of the imperial court has it."

There is no craftsman in the folk who can do water drainage.

"I'll do it." Gu Jiao said.

The old fellow was shocked.

Gu Jiao thought: "however, what I'm going to do next is not water drainage."

Gu Jiao said a title.

"What box?" The old fellow said he had never heard of it.

"Do you have any paper?" Gu Jiao asked.

"Ah?" The old fellow was shocked by Gu Jiao, but he didn't respond to it for a long time.

Gu Jiao simply found a bluestone board on the ground, took out the charcoal pen in her purse, and drew it attentively.

The other blacksmith was attracted by her, and the old fellow blacksmith said, "look at what! Go to work

Due to the authority of the teacher Fu, the blacksmiths forced their curiosity to work, but they still glanced at Gu Jiao from time to time.

What does this little girl draw on the floor of their iron shop?

The old fellow finally refused to resist and asked, "what are you doing, maiden?"

"Painting." Gu Jiaoyan said simply and comprehensively.

"Why are you painting on my floor? I'll have to find someone to clean it later. What a trouble! "

Gu Jiao smiles: "let you finish the remaining 1000 pieces of iron tools in ten days, don't you want them?"

"Ten, ten days?" Old fellow Smith stood up on his hips and said, "don't laugh!"

He's a blacksmith. Can't he know? Even if their entire iron shop people do not sleep, it will take at least a month!

Unless we use the water drainage technology of the imperial court, it will take 20 days.

"I'm not kidding."

The old fellow said he did not believe it.

"What if I do?"

The old fellow Smith looked at her with his arms in his arms and looked down at her. "If you do, your iron tools will be done free of charge to you. Not only that, I'll pack all your ironware in the future! You're not going to get a penny! "

Gu Jiao seriously thought about it and thought that the deal was feasible: "OK, I promise you."

What old fellow did you say? Boast to the sky!

Gu Jiao finished the painting very quickly. She nodded with satisfaction: "it should be like this. You'll find a carpenter later."

What old fellow?

Gu Jiao rolled up her sleeve: "don't be in a daze. If you are in a daze again, your iron tools will not be finished."

After that, Gu Jiao stood up, wrapped the charcoal pen in kraft paper and put it back in her purse. After washing her hands with water, she turned and left.

Old fellow blacksmith is in the face, so can't he? Is the little girl playing with him? How could she understand that?

Doings of ghosts and gods, however, somehow, the old blacksmith thought old fellow squatted on the ground and calmly plotting. He came to the next door and came up with the carpenter.

The carpenter is knowledgeable. After reading the bluestone drawing, his eyes immediately changed: "who painted this?"

"What's the matter?" The old fellow asked strangely.

The carpenter didn't answer him. He knelt down and touched the design with his hands as if he were looking at a treasure. However, he was afraid to touch it.

This careful old fellow made the old blacksmith feel confused.

The carpenter's eyes flashed green. Without saying a word, he went back to the shop, grabbed the pen and paper, knelt on the ground and began to copy the drawing devoutly.

He had a hunch that it might be the greatest thing he had ever done in his life!

The old fellow Smith looked at the pattern on the green slate, left and right. "What is it? Can you really make something? "
