In the past few days, Yang Keshi has been guarding the king of Yun Zhao Kai with his subordinates all the time, while Gao Yuan has taken his men and horses around to hunt and bring back some wild things to improve their food, while Zhou Nan has locked himself and Shen Ding, Sun Rong and others in the camp, thinking about building a carriage every day. There is no need to worry about grain and grass, there is a large amount of grain in the grain depots in the cities of various states, and even in the warehouses of Wufu Village, there are also grain and grass in them, which is enough for their 7,000 soldiers and horses to eat for two months. This is all thanks to Tong Guan and Liu Yanqing, who have repeatedly "sent food" to Wan Shengjun. And Zhou Nan implemented the strategy of elite soldiers, only the elite soldiers were retained, and the veterans and weak soldiers were sent home, so there was a surplus of grain and grass everywhere.

  Each has its own things, that is, no one asks about Zhao Kai, the king of Yun, not even Yang Keshi.

  With such a strange thing as the Three Princes in hand, what else is there to worry about?

  The sound of axes and chisels in the camp every day almost made people forget what they were doing here.

  For Zhou Nan, today is a very important day. After several rounds of refinement, the final shock-proof carriage was finally made.

  The carriage is still only a rough frame, but all kinds of functional facilities have been installed, but they have not yet been decorated and laid. The carriage was wider than Yu Liyan's dismantled carriage, with two people sitting side by side in the front of the carriage, and a vertical baffle of the same width as the carriage, two feet high, blocking the driver in front.

  Behind the riser is a fenced area on both sides, with a roof that extends from the roof of the carport, but is more than a foot higher than the roof of the carport, and the roof is six feet high from the floor of the carport, so that people stand here without touching the top cover, and the fences on both sides can protect the people standing here when the carriage runs.

  Behind the fenced area is the main carriage of the carriage. The carriages are made of double walnut planks with a thick layer of leather and felt sandwiched between the two layers. Zhou Nan tried such a structure, and he couldn't shoot through it at a distance of three zhang with a hard crossbow. The walnut itself is hard enough, and ordinary arrows can't even shoot through a layer of walnut, let alone two layers, and there is leather and felt in between.

  The carriage is only accessible with a door directly in front of it, and there are windows on the board on the sides and rear of the vehicle. The window baffle is on the outside of the compartment, so you can push it open from the inside and pull it back when you don't use it, and it is impossible to pull the window open from the outside because of the mechanism.

  The interior of the carriage has also been completely redesigned. Zhou Nan drew the production of the sofa bed in later generations to Shen Ding, and Shen Ding soon made a sofa bed according to the size of the carriage, which is usually a couch, and there is a backrest sloping backwards behind the couch, which is actually the sofa of later generations. When it's time to lie down, push the sofa forward, fold the backrest, and pull out a section of the same couch from under the seat to become a bed. The ingenuity of Shen Ding lies in the fact that it looks like a complete couch side by side, but in fact, it can be separated from it according to the need, half of it becomes a bed, and the other half is still a couch, or both become beds at the same time. In this era, the most indispensable variety of filling materials is moderately soft and hard, and the sofa is very close.

  Equally ingenious are the small folding tables and built-in storage boxes installed on the interior walls of the carriages. Zhou Nan borrowed the idea of folding furniture from later generations, and asked Shen Ding to install a folding table on the inner wall of the carriage on one side, which can facilitate the people in the car to eat, write, dress, etc., and even put a chessboard on it to play a game. When not in use, it can be folded to form a whole with the inner wall of the carriage. On the other inner wall, a pull-out multi-layer drawer is made to put daily necessities inside.

  As for clothing and other items, after being packed into boxes, they are placed at the back of the carriage and do not take up space in the carriage.

  Under the bottom plate on the left side of the carriage door, in front of the wheels, Shen Ding made a suspension ladder according to Zhou Nan's meaning, which usually fell under the bottom plate, and when he got on and off the carriage, he could pull it out and put it on the left side of the carriage to facilitate getting on and off.

  As for the shock absorption performance of the carriage that Zhou Nan values most, Zhou Nan has already personally tested it. In the field outside the camp, driving at the normal speed of the carriage, Zhou Nan, who was sitting inside, could no longer feel the bumps, let alone panic.

  And on the road, the horse ran very fast, and the carriage was still very stable. The small potholes, which have been offset by felt wrapped around the wheels. The shaking of the carriage was felt only when the ditch was too large and the bow board of the Zhemu could not compensate for the vibration, but the soft and moderate seat was the last pass, and this jolting was reduced.

  Zhou Nan believed that this kind of carriage, which could be compared to the car seats of later generations, would definitely be sold out if it was made and sold to the wealthy and official eunuchs of the Great Song Dynasty.

  But he doesn't want to do a carriage business yet, he only wants to make two.

  Now it is the turn of Sun Rong, a carpenter in the carving line, and Feng Dazhong, a lacquer maker, to help. Zhou Nan's test ride is only a test product, and now two finished cars have been made according to the test product. Since the main Zhemu bow boards were originally reserved, they are now easy to make.

  The basic structure of the carriage has been completed, and Sun Rong and Feng Dazhong are surrounding the carriage and are carefully painting and carving. The whitewash of the whitewash, the carved of the carving. Both of them were born as craftsmen, and their craftsmanship can also be said to be first-class in the Great Song Dynasty. In less than two days, it was basically completed, and only Feng Dazhong was left with the last paint. Zhou Nan's principle is sturdy, durable and comfortable, as for the style of a loser who inlays gold and jade on the carriage, Zhou Nan never thought about it.

  Yelu Yu Liyan, Yinping, and Yu Min also came to see the carriage made by Zhou Nan, and the three of them stared at the carriage and whispered. Gao Yuan was curious, and he came to see it a few times, only to hear Zhou Nan say that he was comfortable to sit on, and he also went out for a run in the experimental carriage. Came back full of praise. This time, Zhou Nan finally made two carriages and rushed over. Gao Yuan knew that one was made for Yu Liyan, so he pestered Zhou Nan to give him the other one, saying that he would keep it for his wife in the future.

  Zhou Nan just smiled and didn't say a word, and Gao Yuan pestered Zhou Nan. Zhou Fu, who was following Zhou Nan, couldn't stand it anymore, so he said to Gao Yuan, "Another Dalang has already been arranged, it is for my sister Yun'er, what are you fighting for?" ”

  When Gao Yuan heard this, he was happy for Gao Yun in his heart, and suddenly said to Zhou Nan, "I'm not as good as you as my brother, but I forgot about my sister." It's been a long time since I've seen Yun'er. ”

  Zhou Nan heard Gao Yuan say that he hadn't seen Yun'er for a long time, and he was also leisurely, full of emotion, and said, "Last year, I spent the New Year with Lao Zhengtou in the mountains, and I still remember it vividly, but I didn't expect it to be another year in the blink of an eye." ”

  Yu Liyan heard on the side that the other one was left for Gao Yuan's sister Gao Yun, and her heart was moved, and she couldn't help but look at Zhou Nan secretly.

  At this time, a pro-soldier from Zhou Nan came and said, "The Southern Dynasty has come and asked to see the princess." "I like Song Chungui, please collect x Song Chungui.
