After the grand morning on the fifth day of the Lunar New Year, at the urging and request of Li Yu, Li Jing and Li Jing, the king of Qi, who were excited, called Chen Jun, the secretary of the military department, and Tao Qian, the secretary of the household department, and took a carriage to the Academy of Sciences for a private visit. Li Yu, Lin Feng, Shi Xubai, Li Deming and other "four giants" of the Academy of Sciences led the way in front of a car. Of course, all the Ouchi guards changed into civilian clothes and scattered to the left and right.

Soon, the group rushed to the gate of the Academy of Sciences. Li Yu, Lin Feng and others jumped out of the car first, and respectfully invited Li Jing and Li Jingsui to get out of the car to visit.

Chen Jun, the secretary of the military department, looked at the flat and wide gate passage, looked at Li Yu and the others a little strangely, shook his head and followed the saint forward.

"Greetings to my emperor, long live long live, long live!" Inside the gate, Chen Chuyao, vice president of the Academy of Sciences and a waiter of the Ministry of War, led all the staff of the Academy of Sciences to kneel on the ground and pay respects.

Li Jing smiled and asked everyone to be exempt, and as soon as he looked up, he was attracted by the seven hollowed-out characters of "science, questioning, and imagination", and took the lead in asking the reason.

Of course, this task of explanation fell on Lin Feng's head, and he briefly explained the origin of the seven characters, and finally summed it up and patted it on the back:

"Holy Lord, as the saying goes, if you don't break it, you can't stand it. If you don't dare to break the existing past, there will be no new future! As long as we grasp the opportunity of science and technology, that is, we have mastered the opportunity of development, Shengshang is far-sighted and long-term, and has grabbed the front of the whole world, and the development of Datang science and technology is just around the corner! ”

Li Jing was praised by Lin Feng with a smile on his face, and under Li Yu's guidance, he turned to the back of the "Seven-Character Academy Training", and two strange carriages immediately came into view.

Both carriages were two-horse-drawn carriages, but they were four-wheeled, and the carriage was longer than the usual two-wheeled carriage, with a square lattice box at the front, and two Academy staff members sat holding the reins.

Lin Feng led the bigwigs into the first carriage, and he and Li Yu followed and sat on it. The wide, long carriage still looked empty with six people seated.

Li Jingsui took the lead in asking: "Zhishan, why did you remember to tinker with the four-wheeled carriage?" ”

"Shengshang, the four-wheeled carriage is not a new fact, as early as the early Spring and Autumn Period in the Qin State there were copper four-wheeled vehicles, but in practical application, due to the road is not suitable, horses are expensive and other objective factors, coupled with the problem of four-wheel steering has not been solved, it slowly disappeared in the long river of history." Lin Feng talked eloquently.

This is the actual situation in history, until the end of the Qing Dynasty, the land of China was basically a two-wheeled carriage. By the end of the eighteenth century, the four-wheeled carriage had the opportunity to gallop across the land of China, but was ruthlessly rejected by China's "national conditions".

In 1792, Magerney led the LinkedIn mission to China and generously presented gifts such as celestial globes, globes, copper cannons, flowering shells, muskets, models of the "Sovereign" warship, telescopes, hot air balloons, and other gifts representing advanced Western technology, including a gorgeous four-wheeled carriage. However, when these gifts were exhibited in the Old Summer Palace, the Qing monarchs and ministers reacted extremely coldly.

When they saw the four-wheeled carriage with a suspension spring, the eyes of a group of cadres were all on the coachman's seat. The chairs were made of soft leather and decorated with small diamonds, which looked extraordinarily ornate, and, for ease of driving and observing the terrain, the seats were designed so high that the ministers immediately decided that it could only be the emperor's "dragon chair". But when they asked, they learned that it was the coachman's seat, and an old eunuch who was in charge was immediately annoyed: "Do you think the emperor can tolerate a person sitting higher than his seat and facing away from him?" ”

In this way, the comfortable and convenient four-wheeled carriage was rejected from the country because it did not conform to the special national conditions of China's "official standard". Of course, Lin Feng would not make this political mistake, so he raised the overall carriage by a part, and deliberately lowered the seat of the groom a little.

Li Jingsui said: "Zhishan, then how do you solve these problems?" ”

Lin Feng smiled lightly and explained: "At present, the Academy of Sciences has found three limestones on the mountains around Jinling City, and the cement will soon be put into use, and when the time comes, the road that is not afraid of rain and rolling will not be a problem." As for the steering, we used suspension steering to coordinate the simultaneous steering of all four wheels. ”

As Lin Feng spoke, he knocked on the carriage, and the driver understood, shouted loudly, and sped up the horse.

"Hey, why is your car fast but not bumpy?" Tao Qian, the head of the household, was the first to notice the abnormality and opened his mouth to ask.

Lin Feng was waiting for someone to ask, and immediately told the secret: "This is because we have installed a newly invented leaf spring on the axle, and the outside of the tire is wrapped with a layer of rubber brought back from overseas, which can absorb the impact and pressure caused by the speed." ”

Chen Jun, the secretary of the military department, looked at the spacious carriage and suddenly asked, "Lord Lin, have you ever thought about applying this kind of carriage to the army to transport food, weapons and other baggage?" ”

Lin Feng said with a smile: "Because of the lack of funds of the Academy of Sciences, this carriage is preparing to walk on two legs for military and civilian use." The carriage can be modified and put into military use, and as for civilian use, on the one hand, it can be sold to high-ranking officials and wealthy businessmen at a price, and on the other hand, it can be considered to be developed as a long-distance carriage. ”

"A long-distance carriage?" This time, it was Li Jingsui who took the initiative to ask.

Lin Feng was like an enthusiastic salesman, and his eyebrows fluttered and he explained: "For example, from the north of Jinling City to the south of the city, from the east of the city to the west of the city, from the center of the city to the Qinhuai River and the riverside, and from Jingshi to the Eastern Capital, several four-wheeled carriages are sent every day, departing regularly, and opening in both directions, there will definitely be people who are willing to pay for this comfortable carriage, which not only saves time, but also enjoys the scenery along the way." ”

This time, even Li Jing, who had not spoken, couldn't help but be moved, this is a new profession that Lin Feng, a ghost boy, came up with!

The carriage first stopped at the Department of Livelihood of the Economic Research Department at the southern end of the Academy of Sciences. When several bigwigs got out of the car one after another to check the springs, rubber, steering and other novelties that Lin Feng had said, Lin Feng offered another surprise.

Fang Tai, who had a black and gray face, came out from behind a thick curtain in the middle of the thick wall, holding a pot of green evergreen in one hand and a pot of red and bright peonies in the other, knelt on the ground, and said loudly: "The Academy of Sciences respects a young plant to the saint, and wishes my Datang foundation a long life; Congratulations to a rich peony, I wish my Tang Dynasty four seasons of glory and wealth! ”

In the bitter winter, Li Jing and several ministers were pleasantly surprised to suddenly see such a festive and allegorical out-of-season plant, and their eyes widened.

Lin Feng took a few steps forward and opened the curtain to invite everyone to visit.

A hot steam rushed from the greenhouse, burning the mood of the group of ministers even hotter. In this greenhouse burned out of an underground fire pit, there were dozens of pots of peonies, moon flowers, and many out-of-season plants that should not appear at this time, which immediately surprised the monarchs and ministers.

Lin Feng still played the role of a tour guide, told the principle of the greenhouse, and solved the mystery of the story of Wu Zetian's cold winter drinking that made a hundred flowers bloom, and even made the eyes of the monarchs and ministers widen, which really ruined their "three views"!

Lin Feng was proud, if it weren't for the fact that the greenhouse of the Academy of Sciences was built too late, the technique was not very mature, and the seeds of various crops were being collected, this time I would have to give these people some out-of-season vegetables to try!

When these people came out, they suddenly came out of the unusually warm room, and a group of people couldn't help but shiver in the face of the biting cold wind. At this time, Fang Tai appeared again, handed over four black cotton jackets, and handed them to the four big guys by Li Yu and Lin Feng.

Chen Jun took the lead in putting on the jacket and immediately shouted in surprise: "What is this dress made of?" So warm and snug to the body. ”

Li Yu personally put a padded jacket on Li Jing. Li Jing remained motionless, enjoying the warm moment of his beloved son's filial piety, and a warmth immediately surrounded his body, which was really warm!

Lin Feng looked at the appearance of the four "soil buns" wearing new cotton jackets, and quickly explained that this was exactly what cotton was made of. The new cotton produced this year, the seeds were removed by hand, and the cotton jacket was played countless times, and the quilted cotton jacket was pressed layer by layer, can it be uncomfortable and warm?

As soon as Chen Jun's body warmed up, his mind immediately became much sharper: "If our soldiers all wear such cotton jackets, will they still be afraid of fighting in the cold winter?"

Lin Feng immediately gave Chen Jun a thumbs up and greatly praised the function of cotton: "Cotton clothes, quilts, a small cotton plant has too many functions, and it can completely allow us southerners to overcome the natural enemy of the cold climate in the north!" ”

Li Jingsui twisted his body back and forth, and found that the effect of this cotton jacket was really unusual, and said: "Zhishan, is there still cotton?" It would be nice to prepare one for the Queen Mother and the Queen! ”

Lin Feng had already prepared, and immediately ordered Fang Tai to move the rest of the cotton in stock to the car at the gate, and there were many skilled craftsmen in the palace, so let them sew it at will!

Walking out of the Ministry of People's Livelihood, the interest of a group of people was even higher. After getting into the four-wheeled carriage, Li Jingsui looked at Wan Nianqing and Peony placed in the corner of the carriage, and asked loudly: "Zhishan, what surprises are there behind?" ”

Lin Feng smiled slyly, pretending to be mysterious: "The mouse pulls the wooden shovel - the big head is behind, naturally there is a bigger surprise!" ”
