Gu Jiao went to the hospital.

Today is the day of the follow-up appointment with the mysterious big man, and the other party is waiting in the Rejuvenation Hall early.

This time, he didn't let the hospital be cleared.

Gu Jiao was a little late because she was bidding farewell to Xiao Liulang, so she asked the other party to wait for a while.

The face of the young guard beside him was completely dark: "Hmph, the person who dares to let my grandfather wait, you are the first!" ”

Gu Jiao spread her hands: "Oh, it's an honor." ”

The young guard skimmed his face.

Gu Jiao entered the wing.

The man wore a hat with a veil to cover his face, but the noble and noble bearing of the first instance could not be concealed.

There are still two subordinates with a feminine temperament around him.

After seeing it a few times, the people had long been accustomed to Gu Jiao's rudeness, and when they saw that Gu Jiao saw that their father didn't even do a courtesy, he sat down by himself, and he could only slander in his heart, but he didn't dare to be sarcastic.

There is no other reason, my grandfather's illness really cured this little girl!

Gu Jiao gave him a total of three injections of benzathine penicillin, one injection every seven days, and the last injection was given last month, and he came over today for a recheck.

Gu Jiao took his pulse and did an examination.

"I'm cured, right?" The man's voice could not hide his joy.

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 without recurrence to be considered a complete cure, and it is not suitable for follow-up." ”

"Uh......" the man was silent.

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

The man smiled and said, "Tell me the truth, I'm leaving." ”

"Oh." Gu Jiao is not surprised, listening to his accent, he doesn't look like a local, and he may not even be from Youzhou, he is from a farther place, and Gu Jiao can't guess where it is.

The man said with a pleasant face: "But I believe that I have been cured by the girl, and I take the liberty to ask the girl, you are so skilled in medicine, I don't know where the teacher is?" ”

Gu Jiao said: "I have a lot of teachers. ”

This is the truth, in her previous life, she studied medicine at a university and a graduate school, and then entered the research institute, and there are indeed many teachers who have taught her.

The man is not a person without eyesight, Gu Jiao didn't want to talk more about this topic, so he didn't ask anymore, he said: "Thank you girl for curing my illness, I have one more thing to do today, that is, I hope to solemnly thank the girl." ”

"You have already paid the consultation fee, so you don't need to thank you......" Gu Jiao was halfway through speaking, and saw the man take a brocade box from his subordinate and put it on the table.

The brocade box is not a vulgar thing at first glance.

Gu Jiao switched seamlessly: "If you really want to give a gift, I can only reluctantly accept it." ”

The subordinates simply don't look at it, you, you have the ability and a little backbone, continue to say that you don't want it!

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

Gu Jiao opened it and saw that it was a delicate and transparent jade folding fan, Gu Jiao held the fan in her hand, it felt slightly cool to the touch, and the jade fat was clear, it was really a good fan.

"Do you like it?" The man asked.

Gu Jiao looked hesitant.

The people are dumbfounded, aren't they, fans made of thousand-year-old cold jade, don't you like this?

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

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

The next people didn't hold back and shook their bodies twice, you really won't be polite, you have to exchange for gold when you come up, but is gold valuable? The rednecks just don't know anything!

The man smiled and said, "I don't have a golden fan, but I have something else here." ”

After that, he summoned one of the subordinates and whispered two words in his ear, and the subordinates' eyes straightened: "Master, this is not appropriate, right?" That's ......."

The man didn't have a good face like Gu Jiao for his subordinates: "Let you take it, what are you doing with so much nonsense?" After going down to Jiangnan, I found that you have other skills, and you are talking more and more. ”

"Yes." The subordinate didn't dare to slack off, glared at Gu Jiao resentfully, and went to the carriage to get a new small box.

It's actually Huarong Dao made of pure gold.

Huarong Road is an ancient educational toy, which is sold in many shops, but it is all wooden on the market, and Gu Jiao, who is made of gold, has seen it for the first time.

It's fun and sparkling, and the little headroom will love it.

Gu Jiao nodded with satisfaction.

The man finally had a small expression on her unsmiling little face, and couldn't help but smile: "Does the girl like gold, or does she like Huarong Dao?" ”

Gu Jiao said: "It's not that I like it, it's my brother who likes it." ”

The man smiled slightly: "The girl still has a younger brother?" ”

Gu Jiao compared her fingers: "It's not one, it's three." ”

Man: That doesn't seem like a good idea!

The man gave Gu Jiao two more gifts, and the people on the side all felt the pain of their own father's flesh, why do you say you are not good? Is this a dead talk? Killed yourself?

There is nowhere to say bitterness.

It's your own good face.

When Gu Jiao left the medical hall, there were three more luxury gift bags in the small backpack!

The man arched his hand at Gu Jiao at the gate of the Rejuvenation Hall: "Girl, there will be a period later." ”

Gu Jiao glanced at him: "There will be a meeting with the doctor later, what's wrong with you?" ”

With that, she carried the small basket on her back and disappeared into the crowd without looking back.

The subordinate was angry, gritted his teeth and said, "Master, 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 smiled happily after he came to his senses: "Yes, what's wrong with me?" Why do you want to see a doctor? Is it bad to be healthy? ”

"Grandpa......"

"It's time to go back to Beijing, let's go."

--

After Gu Jiao left the Rejuvenation Hall, she set off to go to the only iron shop in the town.

This iron shop has been open for more than 20 years, and it can be regarded as an old shop.

As soon as Gu Jiao walked to the door, he heard a ding-dong sound of iron, the business of the blacksmith was very good, and the blacksmiths were so busy that their feet did not touch the ground.

There was no counter in the shop, so Gu Jiao called a guy and asked, "I ordered iron tools here last month, and today is the day of delivery." ”

The guy carried a heavy basket of iron ore and shouted at the lobby: "Lao Wang! Someone came to pick up the goods! ”

"It's coming, it's coming!" A sweaty blacksmith hurriedly ran out, he had a towel hanging around his neck, he wiped the sweat on his face with the towel and looked at Gu Jiao, "Who wants to take the goods?" You? ”

The last time it was the coachman from the Rejuvenation Hall who came to order the goods, so the old blacksmith didn't know her.

Gu Jiao hummed and handed him the pair of cards.

In ancient times, there were still few scholars, and the blacksmiths were not very literate, so they all used pairs of cards, and each pair of cards had a corresponding number, and according to the number, you could know which batch of goods it was.

"You're not done yet." The old blacksmith frowned.

Gu Jiao said: "But last time I said that I would get the goods today." ”

The old blacksmith wiped his sweat with a towel and said, "But it's really not done, and we can't help it." ”

"How long will it take?" Gu Jiao asked.

"This ......," thought the old blacksmith, "a month or two." ”

Gu Jiao was puzzled: "So long?" I don't have too many farm tools, do I? ”

The old blacksmith sighed: "It's not yours, it was a job in the shop last month, and I took it before you, and there are a thousand iron tools for mining iron ore, where can we catch up with a small iron shop?" It's more than half there! There are not enough people, and there are not enough stoves......"

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

"Huh! Here it comes! The old blacksmith yelled at the shop, then turned to Gu Jiao and said, "Girl, you should come back next month." ”

Gu Jiao didn't want to wait that long.

After the old blacksmith went in, she also went into the blacksmith's shop, and the men and the blacksmiths were so busy that no one paid attention to the little girl.

In all fairness, there are not many people in the iron shop, and according to this number, it is enough to make a thousand iron tools a month.

Then the problem should not be a shortage of manpower.

Gu Jiao looked at their blast furnace again, and immediately found the problem.

Iron smelting requires extremely high temperatures, and in order to achieve this temperature, blast furnaces generally use blower appliances. Gu Jiao originally thought that the iron shop of this dynasty also used water row blower, but who expected that it turned out to be the most primitive manpower blower.

The biggest disadvantage of manpower blasting, commonly known as human platoon, is that there is only one tuò (pouch made of horse skin) for an interface, and the manpower blast is closed once.

A blast furnace has about four to six connections, in other words, a blast furnace can blast up to six times at the same time.

This is much less efficient than draining.

The water drain is pushed by hydraulic power, and the drain can be closed several times every time the water wheel rotates, which not only greatly saves time, but also saves manpower.

Gu Jiao told the old blacksmith what she thought.

The old blacksmith was very surprised, how could a little girl in a cloth dress still understand this?

After being surprised, he said: "I have seen the one you said, and only the iron shop of the imperial court is available." ”

No craftsman in the folk can make water drains.

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

The old blacksmith was shocked.

Gu Jiao thought for a while: "However, what I want to do next is not to drain the water." ”

Gu Jiao said a title.

"What's the box?" The old blacksmith said he hadn't heard of it at all!

"Is there any paper?" Gu Jiao asked.

"Huh?" The old blacksmith was already stunned by Gu Jiao, and he didn't react for a while.

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

Other blacksmiths were attracted to her, and the old blacksmith scolded, "Look what! Let's all work! ”

The blacksmiths were hindered by the majesty of the master, and forced their curiosity to work, but they still glanced at Gu Jiao from time to time.

What is this little girl drawing on the floor of their iron shop?

The old blacksmith finally couldn't help but ask, "Girl, what are you doing?" ”

"Paint." Gu Jiao said succinctly.

"Why are you painting on my ground when you're fine? I have to find someone to wipe it when I go back, what a trouble! ”

Gu Jiaowaner: "Don't you want to let you complete the remaining more than 1,000 pieces of iron tools in ten days?" ”

"Ten, ten days?" The old blacksmith straightened up, "Don't laugh! ”

He's striking iron, can he still be unclear? Even if the entire blacksmith didn't sleep for more than a month!

Unless it is to use the water drainage technology of the imperial court, but that will also take twenty days.

"I'm not laughing."

The old blacksmith expressed disbelief.

"What if I did?"

The old blacksmith clasped his arms in his hands and looked at her condescendingly: "If you do it, I will make those iron tools of yours for free, and I will not charge you a copper plate!" Not only that, but I'll cover all your iron tools from now on! You don't want to be alone! ”

Gu Jiao thought about it seriously and felt that this deal was feasible: "Okay, I promise you." ”

Old blacksmith, why did you agree? Blow it to the sky!

Gu Jiao quickly finished the drawing, and she nodded with satisfaction: "It should be like this, you can find a carpenter to come over in a while." ”

The old blacksmith opened his mouth: "What? ”

Gu Jiao rolled up her sleeves: "Don't be stunned, if you are stunned, your iron tools will not be finished." ”

After that, Gu Jiao stood up, wrapped the charcoal in kraft paper and put it back in her purse, and then turned around and left after finding water to wash her hands.

The old blacksmith looked blindfolded, this and this, this can't be, right? The little girl is playing with him? How could she possibly understand this?

However, for some reason, the old blacksmith thought of the other party squatting on one knee on the ground and drawing calmly, so he still went to the next door and called the carpenter over.

The carpenter is knowledgeable, and after reading the drawings on the bluestone slab, his eyes immediately changed: "This, who drew this?" ”

"What's wrong?" The old blacksmith asked curiously.

The carpenter did not answer him, he knelt down, and reverently touched the blueprint on the ground with both hands as if he were looking at a treasure, but he did not dare to touch it for fear of touching it a little.

This cautious look puzzled the old blacksmith.

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

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

The old blacksmith was confused, staring at the pattern on the bluestone slab, looking left and right: "What's the matter?" Can you really make something? ”
