"The problem at the moment is the budget, and this palace must know what Xia Shangshu thinks." Zhu Gaochi sighed.

Cheng Yuan also understood Zhu Gaochi's difficulties when he heard them, after all, this shipbuilding is not as simple as eating and drinking, and he thought at the moment that he could collect business taxes in advance.

"Raising the commercial tax, I have discussed this matter with Your Majesty before, I don't know what Your Highness thinks of this matter?" Cheng Yuan asked.

Several people who support Zhu Gaochi are important figures in civil officials, and for this kind of thing, in addition to writing to Zhu Di to report, he will also ask Eryang for an explanation.

Sure enough, Zhu Fatpang thought that how to implement it and how to implement it needed to be discussed with the three scholars, so Cheng Yuan had to wait a few days.

Thinking that Xiao Banyue didn't go back, Cheng Yuan looked for the rain coat and rode home, and when the problem was at hand, it was impossible for the treasury to take out too much money to build ships and equip the sailors.

Second, Zhu Gaochi also had to discuss with Wenchen.

…………

Zhenguo Mansion, Study.

"Arithmetic, geography, chemistry, and even medicine and the imperial examination are all very worthy of a lifetime of discussion, for example, now I am looking for an empty jar to come to you, what is in it?"

Shangguan Yun said, "Teacher, there's nothing in this empty jar." ”

"Lan Zhou, Song Jing, what do you think is in it?" Cheng Yuan looked at them with hope in his eyes.

Seeing that everyone didn't answer, Cheng Yuan said: "The invisible and untouched substance in this is called air, if someone covers your mouth and nose, how will you feel?" ”

"Kick him!" Wei Lanzhou said.

Cheng Yuan: "......"

"It's going to suffocate." Song Jing said.

"That's right, because there is no air, so it will suffocate, and air is invisible and intangible, but it is extremely important."

Cheng Yuan said: "Therefore, what I want to teach you is chemistry. ”

Seeing that everyone didn't understand, Cheng Yuan said: "It is the nature of all things in heaven and earth, the doctrine of change, which obeys the law of conservation of mass, that is to say, if you exhale a breath, then the air you inhale will produce a corresponding reaction."

If you don't understand it, you can say that the meat will be rancid when it's hot, the sword will rust, and this embroidered ......"

Wei Lanzhou stood up and said, "How can a person who practices martial arts let the sword rust, this is simply ......"

Cheng Yuan thought about it and learned from it.

Changed to geography, he said, "The Ming Dynasty now has rivers, rivers, and even lakes, seas and mountains, that is, the study of the direction of mountains and rivers, the places where people live, and the changes in spring, summer, autumn and winter, which is geography." The Ming Dynasty is divided into north and south, Jiangnan, north, Liaodong, and Mobei, all of which can be called geography.

The most understandable thing is that the thousand acres of greenhouses outside the city, also called the greenhouse, if you understand the geographical changes in the future, you can control the laws of heaven and earth. ”

Kuang Yu stood outside and listened to Cheng Yuan's endless talk, glanced at the snacks and fruits prepared by the swordsmen, and said: "These dozen things, the teacher will definitely not be able to eat them, if you don't finish eating, it will be easy to spoil, rather than let it undergo chemical changes, it is better to eat it into my stomach." ”..

The squire shook his head: "Your Highness was afraid that the horse would be hungry, so he asked me to prepare, what do you know." ”

"Kuang Yu, you can eat it, a lot." Princess An Cheng came over and smiled.

After Cheng Yuan finished speaking, Kuang Yu went in and showed him the stitches he had sewn a few days ago, Cheng Yuan shook his head, brought Princess An Cheng over and said, "Your Highness, you will teach Kuang Yu embroidery in the next few days." ”

An Cheng was surprised: "How can a man ...... If you need to do any embroidery, this palace will do it for you. ”

Cheng Yuan ordered the kitchen to slaughter a sheep, peel off the fresh sheepskin, pull a piece of blood, use a three-edged blade to make a fool on it, poke it with a dagger, and then cut it with a knife, and finally pierce it with an arrow, hand it to Kuang Yu and say: "You stitch up all these wounds, I will take a look and give you advice." ”

Seeing the fresh sheepskin pulled by the blood, An Cheng couldn't help but vomit, Cheng Yuan smiled:

"I'll help Your Highness go to the chair and sit down first."

Kuang Yu is good at grasping medicine to cure diseases, but he is not very skilled in suturing this kind of suture, and Cheng Yuan has been cultivating him these days to be able to sew any wound.

Not only to be able to sew, but also to look good, as far as possible to leave less scars, this kind of technique he recommended to know embroidery An Cheng pointed out Kuang Yu, the embroidery skills and medical skills of the two in one.

Cheng Yuan took the three-edged blade, put it in the cabinet not far from Princess An Cheng, turned around and said to Kuang Yu:

"This three-edged knife is specially made by me, and then operated by the court for the prince and officials, I reduced their length, polished them, and set up three blood grooves to come out.

If you go to the battlefield, you can leave a wound that is difficult to stitch up for others, but the power is far less than that of a three-edged thorn.

The three-edged thorn shape has a pointed head and a thin body, and at the same time has three twisted blades and three blood grooves. The Soldier Sweep will kill them with a blade, and the Triangular Thorn will come in handy, and if you stab an enemy, the person will only wait for the blood to dry up and die.

This kind of triangular knife, the Ministry of Industry has begun to build and produce, it is easier to carry, extremely sharp, if you want to stitch this, you must be accurate, as soon as possible to stop the bleeding, otherwise it is easy to fall into a coma. ”

Cheng Yuan said and ordered someone to bring a piece of tofu, smooth and white, he stabbed it with a three-edged knife, pointed it to Kuang Yu and said: "I will now ask His Highness to embroider it with her embroidery technique, and then you use the method of sewing the wound to stitch it up." ”

"Master, how can tofu still withstand embroidery?" Kuang was puzzled.

Cheng Yuan went over and helped An Cheng over: "Is Your Highness ready?" ”

"This method is not difficult, Kuang Yu, this palace will embroider it for you, and you should pay attention to the needle drop......" she said, and began to sew the tofu together.

Cheng Yuan pointed out beside him, saying how to sew the skin and flesh, and what to pay attention to when removing the stitches at the end.

Although she is pregnant, embroidery is a habitual thing, it is not difficult, and she is very familiar with it.

Kuang Yu has a foundation for sewing wounds, and it is indeed a difficult problem for him to stitch up the extremely tender tofu without too many traces.

In the evening, the Guogong Mansion ate mutton, Princess An Cheng did not forget Zhu Yunwen, and at night, let Cheng Yuan send the mutton to her cousin.

Zhu Yunwen said: "Ah Zhen, you are much more affectionate than them." ”

"What do you say, hurry up and eat." Cheng Yuan stood in front of Zhu Yunwen, afraid that this imprisoned person would do any harm to Zhu Zhizhen.

Seeing this, Zhu Yunwen said: "I have known you for a long time, I thought you were a vicious person, but I never thought that you were very good to Ah Zhen." ”

"I won't be like some people, who can even leave their wives and children behind in order ......to survive," Cheng Yuan said with a poisonous tongue.

originally thought that Zhu Yunwen would fight back, but he just shook his head: "Our cousins and sisters were always with each other when they were young, and Ah Zhen and Ah Ying both had a good relationship with me, don't live the belly of a gentleman with the heart of a villain." ”

After Zhu Yunwen finished speaking, he ate the meal calmly, as if the imprisonment of the past few years made him seem to have lost his temper.

Cheng Yuan didn't believe in this evil, and in order to be foolproof, he told her that she couldn't go again in the future except for letting Liu take care of it.

An Cheng pinched his waist and motioned him not to poke people's scars, but he also nodded in agreement.

Before leaving, Cheng Yuan said: "The winter moon is cold, take the bed and quilt to him in a few days, so as not to freeze to death." ”

Zhu Yunwen: "............"

………………

In the fifth year of Yongle, in May, it has been rainy recently.

Cheng Yuan looked at the fried tofu, stewed tofu, mapo tofu, and tofu soup on the table in recent months, glanced at Kuang Yu, and said with a smile: "Kuang Yu, since you started practicing sewing, from last winter to now, the teacher has eaten tofu every day.

Your master is going to give birth at the beginning of this month, and you are still practicing, how many pieces of tofu have you ruined with this acupuncture. ”

Cheng Yuan put the winter melon pork rib soup into the bowl, handed it to the servant and said, "Send it to His Highness, and then let the kitchen make some light dishes." ”_&
