Siheyuan: I decide the fate of the world with my medical skills

Now, the internal control method of two-wheeled carriages popular in the western half of Asia, the entire European continent and even the northern coast of Africa is to fix the reins directly to the horse's neck. During driving and pulling, this design causes the horse's neck to bear huge forces, and excessive pressure may compress the horse's trachea to the point of suffocation. This condition significantly limits the running speed of horses, and the same phenomenon also occurs when they pull oxen. At this time, the Qin State adopted another advanced driving method: the force field of the running horse is concentrated in the area near the armpits, thus avoiding obstruction to normal breathing. As a result of this design, although the overall design is relatively tall, it has better safety in maneuvering operations such as emergency turns.

The unique advantage of four-wheeled vehicles is that they do not propel the entire vehicle body by horsepower, but rely on the cooperation of the front wheels and the vehicle steering system to propel the guide wheels and the vehicle body forward, reducing the speed instability caused by the change of the center of gravity. With this in mind, in order to optimize driving smoothness and reduce the impact of lateral resistance, Fusu designed a new front wheel with a more moderate size. After adding steering and steering mechanisms, the vehicle's linear motion performance has been improved. In addition, despite the lack of a differential common in modern cars to adjust the rotation speed of the tires on both sides, other characteristics of four-wheeled vehicles still ensure their reliability in large-scale use. This is because the different motion modes and problem types that the vehicle needs to deal with are different, that is, lateral movement has more degrees of freedom than axis rotation, and it is easier to achieve balance and stability control.

After completing the preliminary design and examining his own caravan concept, facing the glorious double-drive carriage of a long-lived queen in history, Fusu decided to build a special car for himself to distinguish his real power under his noble status. After the Indian Ocean, she is the king, but I am! Dreams and actions, as a matter of course!

Despite the inability to create spring technology, support for traditional leaf springs for vehicles remains strong. This element is added to vehicle stability and comfort. The carriages of ancient emperors were often equipped with luxurious vehicles pulled by up to six horses. The maximum force that each strong animal can exert is about half of the horsepower of a human, so the combined force of six horses means that they have three times the power of a single horse. This means that the vehicle can easily be loaded with a variety of equipment such as reclining chairs, workbenches, heating devices or cooling equipment.

For an imperial leader, protection and safety are never negligible. Therefore, the main body of the cockpit is made of reinforced steel. Large glass windows are good, but they are inappropriate under the principle of "a gentleman should not stand under a dangerous wall". The existence of weak links may cause unexpected risks. It is safer and more feasible to follow the traditional approach of solid and practical.

Fusu simply conceived the general framework, and the exquisite external decoration work was naturally handed over to specialized craftsmen.

It is estimated that the total weight of his special vehicle after the improvement is close to the luxurious vehicle of the Qin Emperor period - the "Golden Root Car". This also suggests that the new model can fully adapt to the current road conditions and will not hinder traffic.

After drawing up the final design plan and properly wrapping up the work, Fusu's entourage arrived at the end of his journey, the royal hunting ground called "Shanglinyuan".

However, he was not here to inspect the army. Instead, he was here to see how well the gilts could do their job as mothers—well, no, actually he was here to give instructions on how to breed excellent strains of piglets.

In the eyes of the First Emperor, pigs are cute and delicious.

Twice-cooked pork, braised pork, steamed pork with rice flour, and even the healthy and decadent pork skin... just think about how mouth-watering each of these delicacies is!

One of the biggest advantages of raising pigs is that these pigs have a very good appetite and produce a lot of excrement, so a large amount of organic fertilizer can be produced for use in farmland.

The benefit of raising pigs is that they are omnivorous animals. They can eat feed, such as corn, rice and other cereals; they can also eat pig food and so-called "super energy supplements" (here it means all kinds of feed or high-nutrition food that pigs can eat), but they may grow a little slower.

In contrast, livestock such as cattle and sheep only give birth once a year, and each time only one baby is born. But piglets can give birth to more babies at a time!

The pigs that were carefully taken care of by the First Emperor in Shanglin Garden were not piglets for consumption, but pigs carefully selected from various types of pigs brought from all over the country. About half of them were the Bada Eyebrow Pigs unique to Guanzhong (this name sounds quite interesting).

According to folklore, the Bada Eyebrow Pig has a distinct feature: a long and narrow head, large and drooping ears, and horizontal and vertical lines on its forehead that resemble the letter '8', hence the name.

What made the First Emperor most regretful was that the Taihu pig, known as the "national treasure", had not yet been fully cultivated and developed.

The term "national treasure" means that Taihu pigs produce far more piglets each time than other types of sows, often more than a dozen at a time... or even more!

The First Emperor vaguely remembered that in some database, people who raised Taihu pigs usually used a diet rich in phosphorus but low in calcium. Such food was particularly effective in promoting the growth and development of piglets, such as feeding piglets with wheat flour and water sponge.

Although it is unclear whether his descendants can accurately master the breeding technology of future generations, he at least has mastered the basic knowledge of breeding - giving priority to fast-growing and large-bodied pigs for breeding, and the rest are for slaughter and food. This is a direct and efficient route!

In the 26th year of the reign of the First Emperor, the unified Qi territory was divided into four counties. That is, the eastern part was Linzi County, the capital of Qi, the central and western part was Jibei County, the southern part was Langya County near the sea, and Jiaodong County was established on the Jiaodong Peninsula. The geographical location of Linzi County to the north of the Jishui River corresponds exactly to today's Gaoqing, Shandong.

The history here has a common feature with other cities in Qi in that most of the nobles have the surname "Tian", which can be traced back to the "Tian Chengzi era". "Tian Chengzi" aimed to expand the power of the Tian family. He selected Qi women who were more than seven or eight feet tall as concubines and allowed his guests to come and go freely without any restrictions. As a result, nearly seventy children were born, and most of them were later entrusted with the right to rule different areas of Qi, laying the foundation for the Tian family to replace the kingship at that time.

When the State of Qi was established, although Qin Shihuang moved 12 powerful families to Guanzhong, he did not substantially weaken the powerful class centered on the Tian family in Qi. Therefore, the Tian family still remained an important force in Qi.

Their surnames may have changed from frontier officials to ordinary civilians, but their property and land are still endless, and the number of servants is still in the hundreds.

The Jiang family has taken root and multiplied in Qi for hundreds of years, and its roots are deeply ingrained.

The Qin Dynasty could demote them to commoners and deprive them of their land resources and land rights, but it could not sever their power and influence in Qi for hundreds of years from the dimension of time!

If one hopes to shake this foundation within a dozen years, there is no other way except to follow Chang Gong's strategy of "stones must be broken if they are moved, and people's hearts must be changed."

Among today's wealthy families, the most representative ones are still the family of Tian Dan, the former ruler of the State of Qi.

Just like the grass and trees that bend when the wind blows, after the Qin general Wang Ben conquered the State of Qi, he had already split his huge family into several parts and gave them to his cousins ​​Tian Heng and Tian Rong.

It was to avoid the imperial court's order to relocate the powerful.

That afternoon, three young men with hurried looks and well-dressed appearance came to the house of a wealthy man.

The young man leading the team was about forty years old. He was wearing a green tight robe, had a beard that reached his chest, and had a slightly dark skin. However, his handsome eyebrows and eyes showed that he must have been a handsome and heroic young man in his youth.

Specifically, the two people accompanying him behind him - a burly and majestic man with a waist nearly six feet wide and a young man with a tense expression looking around the surrounding scenery - seemed relatively less eye-catching.

The person in charge of the village who was guarding the entrance of the alley showed some fear of the big man and wanted to stop him from entering, but he decided to remain silent and not try to stop him.

The three young figures walked around for a while before stopping outside the gate of a spacious courtyard. However, what caught the two's attention was not the courtyard's unconventional structure, but the Qin yamen runner kneeling at the gate in a black official robe.

“People all over the country kneel to show respect to court officials, but I didn’t expect that in Qi, the officials would kneel to the common people. It’s quite rare.” The young host smiled and shook his head, then asked the tall and strong man to step forward and press the knock hole on the wooden door.

"Bang! Bang! Bang!"

A knock on the door broke the quietness. A young man opened the door, muttered something, and then his eyes lit up as he looked carefully at the stranger who suddenly visited the door.

"What's your name?" The young man immediately stepped forward and bowed, saying, "Brother Tian, ​​please forgive me. How about addressing me as Earl?"

The young guest quickly replied, "I am Master Zhang Liang, no need to be so polite."

"If my brother knew that I called you by your full name, Zhang Liang, he would definitely break my legs. You can imagine how severe the punishment will be." Tian Rong raised his head and touched his hair, saying a little embarrassedly.

Zhang Liang smiled, pointed at the young man beside him and said in a low voice: "This is my new adopted son. His name is Chan, and his courtesy name is Bo. He was originally the youngest son of Xiang Yan, a general of the State of Chu during the Warring States Period."

"I have heard about the deeds of the Xiang family before. Today I see that they are indeed as talented as the rumors said. I am so sorry for my disrespect..." After paying his respects to Zhang Liang, Tian Heng bowed respectfully again to show his respect.

After the two men exchanged greetings, Zhang Liang pointed at the strong man and asked, "My dear brother, Brother Tian Rong, why don't you try to guess who he is?"

Tian Rong looked up at the big man and praised him a few times: "Could it be that you are the brave hero who assassinated Qin Shi Huang?"

"You're talking about me, the king." The big man patted his chest heavily.

Tian Heng was a little surprised. Seeing that Zhang Liang was indifferent, he also showed indifference.

Before the Qin Dynasty, the common people could use the title "朕". But that person, in order to show off his noble status, strictly prohibited people from using this title as their own.

However, there was nothing special about the use of this word before, but now when I hear this voice, it is particularly majestic! From now on, I can also call myself "Zhen"... Tian Heng secretly made up his mind, and then revealed the identities of Zhang Liang and others to the other party.

Zhang Liang saw that the door was closed, so he walked over and asked, "Who is that person?"

"Brother Zhang, are you referring to the captive outside the gate?" Tian Heng said with a smile, "That's the county magistrate. His son trampled on a farmer's rice seedlings while on patrol. The farmer had no choice but to find his brother, who then compensated him for his losses and claimed that the punishment for the offender should be borne by his father, so he ordered his son to wait here for two full hours as punishment!"

Xiang Bo listened to Tian Rong's story and chuckled in his heart. Tian Dan's punishment order was so harsh. If he punished his son as well, how could he survive in the local area? The things behind it... But that's none of my business!

They went on for a little while, and came across an open arena, with a high platform for archery in the distance, and racks of weapons around it, filled with axes, hatchets, hooks, forks, and other weapons.

The fighting arena was made of fine sand and gravel, and at this moment, dozens of people were fighting on it.

On the other side, several sturdy men on half-naked riders were running around the field, occasionally drawing their bows and arrows, practicing equestrian shooting.

Di County is far away from Xianyang Prefecture, so Qin's retreat order has no effect at all in this land.
