    The second day.

    Zhao Chen yawned comfortably and woke up. The level of comfort in Zhao Manor was unmatched by Jiannan Road.

    Changle still woke up early and must have gone to the palace. In addition to taking care of the children, Changle is now the director of the Datang Sports Bureau. She needs to further promote various sports.

    I got up and had breakfast. The breakfast was rich and varied. After all, the greenhouse area and breeding area of ??Zhao Manor are already very rich.

    While having breakfast, a voice sounded: "Mr. Zhao."

    Zhao Chen looked up and saw Pei Xingjian coming. Pei Xingjian seemed to be taller than before. Although he looked like a teenager, he still had the heart of a child.

    "Xiao Pei, are you so happy so early in the morning?"

    Pei Xingjian said with a smile on his face: "Don't you know that your husband is back, so you came here specially to do the job?"

    "Have you passed the imperial examination?"

    ¡°Sir, don¡¯t worry, the exam has already been taken, and we are still waiting for the results. Sir, you can rest assured that this imperial examination will definitely be the scholar¡¯s ??high school in our Zhao Manor!¡±

    Pei Xingjian is extremely confident.

    Because the imperial examination training in colleges and universities is unique in the entire Tang Dynasty, the imperial examination questions are broken down and taught to you, and you are even taught how to write policy papers step by step, which is completely comparable to the tutoring classes of later generations.

    Zhao Chen hummed: "If you don't pass the exam, don't come to see me."

    "Don't worry, Mr. Zhao, you will definitely pass the exam."

    Zhao Chen looked at him and kept looking at the breakfast: "Okay, okay, sit down and eat together."

    "Thank you, Mr. Zhao, I'm not welcome."

    He sat down and immediately picked up the chopsticks excitedly to pick up the buns.

    Zhao Chen rolled his eyes, you¡¯re really not polite.

    After finishing eating, Zhao Chen got on his bicycle and slowly inspected a circle of the manor. Now the manor's farming area has been extended a lot outside the manor, because the number of people in the manor is always increasing, except for the greenhouse area.  In addition, the breeding area and agricultural area are basically outside the manor.

    The simple wooden houses that were just built for Qin Huaidao and the others have long since been demolished and replaced with better houses.

    The dealers on the road all have smiles from the bottom of their hearts, and they live a prosperous and promising life.

    Along the way, many dealers, whether riding bicycles or walking, greeted Zhao Chen.

    Afterwards, Zhao Chen went to the school district to take a look. In addition to the high school district, the primary school district was also full of students. All the children of ordinary families in the manor could come here to go to school, and the teachers were all in the high school district.  teacher.

    The college campus is now the second busiest place in the entire Zhao Manor. Many scholars can be seen arguing fiercely everywhere, and many scholars are in front of the exhibition column, reading the latest issue of the weekly.

    At the same time, Zhao Chen will also add some new majors and continue to improve the professional structure of higher education campuses.

    Afterwards, Zhao Chen went to the industrial area again. The industrial area was now the busiest place. To the east of the industrial area, on the newly built roads and parking lots, there were many horse-drawn carriages and bicycle trucks parked full of things.  All are raw materials needed by various workshops.

    There is still steam and smoke rising from the chimneys in the workshop area.

    It feels a bit like London in the industrial era.

    Zhao Chen inspected each workshop again, and then went to see Li Tai.

    Li Tai has made some progress. He first made a small model based on the principle of a hot water kettle, which can also simply drive the operation of the belt. However, some key nodes have not been completed yet, and the model needs to be enlarged dozens of times.  The difficulty will be extraordinary at that time.

    After encouraging Li Tai, Zhao Chen walked out again.

    "Mr. Zhao, what will you do next?"

    "How is the construction of official roads across the country going?"

    Pei Xingjian replied: "The official roads between major cities are being built very quickly. The official road from Luoyang to Chang'an has been built, and further west to Taiyuan, the official road from Shandong to Taiyuan is also being built soon, and south to Su  Hang, it¡¯s almost too soon.¡±

    This time the official roads of the Tang Dynasty were built by basically sending craftsmen from two cities to build them in opposite directions. Although it was more difficult to do so, it was indeed one of the fastest ways.

    "In that case, we can invent a four-wheeled carriage."

    Zhao Chen said thoughtfully.

    The carriage he rode on Jiannan Road before was too bumpy. Although bicycles are very popular now, carriages are still necessary.

    In addition, the official roads are now built, and horses canIf you run wildly on the road, then the four-wheeled carriage can come out.

    Four-wheeled carriages are mainly used in the West. In ancient China, more two-wheeled carriages were used. Compared with two-wheeled carriages, four-wheeled carriages are more comfortable and can turn freely. Unlike two-wheeled carriages, the front  Once the carriage turns, the carriage behind it drifts completely out of the aisle.

    ?? Four-wheeled carriages have shock absorbers and four-wheel steering devices. Of course, this is not to say that ancient China did not invent these things, but that in ancient China, there was no need for four-wheeled carriages at all.

    Why, because the first point is that the wheel diameter during the Warring States Period in ancient China was 1.69 meters, while in ancient Rome it was only 0.5 meters. Large wheels mean a high chassis, good passability, and can be driven on uneven places.

    The second point is that in the West, the horse rope is tied around the horse's neck, while in ancient China, the horse rope is tied around the horse's chest. If someone has a rope tied around your neck, can you still run fast?

    The third point is that the carriages in ancient China were actually on rails. Just like the trams of later generations, there were sunken ruts on the ground.  When running on the road, you don¡¯t need to worry too much about steering. So is it necessary to use a four-wheeled vehicle?

    But now the situation is different. Now that the official roads of the Tang Dynasty have been built and the wide roads, the carriages must be faster, and the requirements for control must be higher. Four-wheeled carriages have the possibility of appearing.

    Pei Xingjian¡¯s eyes lit up: ¡°Sir, do you need my help?¡±

    "Are you not helping me? Just do what you have to do."

    Pei Xingjian said oh, a little aggrieved, and Zhao Chen called a few craftsmen, and soon someone brought a carriage, and several scholars were analyzing beside him.

    While Zhao Chen was talking, he pointed out the flaws of the carriage and ways to improve it, and the scholars took notes carefully.

    Everything in the experiments in the industrial zone must be recorded for easy inquiry. This is also Zhao Chen's requirement.

    Soon, the requirements for the four-wheeled carriage were announced. The craftsman responsible for making the wheels immediately started to make the wheels. This time, the wheels did not need to be made of wood, but of steel!

    And the hub of the wheel does not need to be so big.

    Zhao Chen almost even drew the design drawings. The craftsmen understood it as soon as they saw it, and immediately started making it according to Zhao Chen's requirements.  (Remember the website address: www.hlnovel.com
