Lantian arched his hand, Lu Jia took him down to get the roster, and then went with him to count the displaced people outside the city.

The village chiefs came forward one after another to promise this matter, after all, if they don't agree, they won't get any benefits.

Lan Hu and Zhao Zhong began to help Lu Jia deploy the displaced people outside the city, and Zhao Tuo led the soldiers to maintain good order.

With sufficient labor to join, the construction of Longchuan transportation has entered a new **, and the construction of various wharves and post roads has been further accelerated, so Li Tangshan took the opportunity to tell Zhao Tuo that he wanted to build a wooden road for experiments, but Zhao Tuo did not understand what this brother-in-law wanted to do at all. It's just that last time Li Tangshan and Lu Yi's bamboo building made Zhao Tuo earn enough face in front of Lan Xiaoni, but he was very happy and promised to fully cooperate with Li Tangshan. Zhao Tuo also expects that Li Tangshan will always make an incredible southwest and west, and Zhao Tuo is also used to Li Tangshan always likes to toss.

Li Tangshan wanted Zhao Tuo's permission, and with Zhao Tuo's support, Li Tangshan could make the best use of the resources of Longchuan County to do the experiment of wooden road transportation.

Li Tangshan and Lu Yique are on the slope of the northwest of Longchuan County.

The slopes here should not be too steep, and gravity is used to glide automatically. Li Tangshan asked Lu Yique to bring dozens of carpenters selected from the homeless people, and asked the homeless people to clean up the plants first, tamp the roadbed first, lay stones and fine sand on it, and then install wooden rails.

Li Tangshan asked Lu Yique to design the drawings in advance to make a small car, put it on the wooden road and stop after running dozens of meters, but the speed could not be made at all, everyone went forward to study what was going on, and found that the friction between the axle and the wooden rail was too great, and the cow horse was very difficult to pull up, and the parallel line of the wooden rail could not meet the requirements, and it was stuck after a few steps.

Li Tangshan didn't know what to do for a while?

Lu Yique suggested that the wooden wheel be changed to the size of a horse-drawn carriage, and the iron sheet of the middle shaft was lubricated with animal oil. Li Tangshan felt that he was moral, so he asked Lu Yique to take the carpenter to modify it according to Lu Yique's meaning.

Lu Yi's level of these carpenters is very high, and a new test car will be done half a day later, Li Tangshan is running on the flat ground much smoother than the one just now, the new vehicle ran 500 meters on the wooden track, Li Tangshan looked at the wooden road car running a little bit of a modern train feeling.

Li Tangshan turned around and said to Lu Yique: "The descendants of Duke Lu, it is really not simple, and the skills are extraordinary!" ”

Lu Yique shook his head worriedly and said: "Master Li, I personally think that the wooden road car only has its shape, and it is not necessary, and it is still far from the real operation. ”

Li Tangshan looked at Lu Yique strangely and said, "What's the problem?" ”

Lu Yique shook his head and said that he didn't know, Lu Yique shouted to the carpenter in the distance: "Gong Bing, Gong Jiang, Gong Jian, you add some goods to the wooden road car, Xianyang Wu, Liyang Chong, Linjin, you pull the car back to the original place." ”

Everyone listened to Lu Yique's order, and everyone got busy again.

Li Tangshan looked at the sky in the distance, and the sky was full of clouds, and a storm was coming.

The sky that was still clear just now suddenly became a big black curtain, covering the entire sky, even the most dazzling sun disappeared without a trace, the clouds in the sky were getting lower and lower, and it was about to rain, and the pedestrians on the road avoided in time, Li Tangshan asked Lu Yique to ask everyone to pause first, and Lu Yique asked everyone to quickly hide under the eaves to avoid the rain, hoping that the rain would stop quickly.

It was raining heavily outside, and I couldn't do much this afternoon.

Li Tangshan comes from modern times without any hierarchical concept, and also has great respect for scientists and skilled craftsmen. Soon mingled with them, Li Tangshan was especially attentive to remember their names: ""Gong Bing", "Gong Jiang", "Gong Jian", "Xianyang Wu", "Liyang Chong", "Linjin".

The carpenters also felt that Li Tangshan was very different from other officials of the Great Qin Dynasty, and everyone also liked Li Tangshan's character, and no one would pay attention to them again.

They told Li Tangshan that they couldn't stay in Longchuan for a long time, because the construction schedule of the Lishan Imperial Mausoleum was tight at the end of the year, and they all had to return to Xianyang City to participate in this big project. Li Tangshan expressed his understanding and asked the six of them to cooperate with Lu Yique tomorrow to do the test of the rail car.

Li Tangshan instructed Lu Yique to produce a few more cars in the form of this car, whether it can form the effect of a train, so that the carrying efficiency will be greatly improved.

The next morning, when the weather cleared, Li Tangshan and Lu Yique brought their team members to the test site. The carpenters had their vehicles ready early, and how they could connect several cars one by one would make the carpenters stumped.

Li Tangshan also has an empty stomach theory, and he can't solve practical problems. At this time, Lu Yique and Gong Bing, Gong Jiang, Gong Jian and other carpenters studied how to solve the problem of connecting the vehicles to form a small train. Soon after, Gong Bing and the others came up with a solution, and the carpenter also felt that it was feasible, so they worked together to assemble the wooden road train.

Li Tangshan asked everyone to put the car on the wooden rail, using manpower for dozens of meters, and running smoothly. Li Tangshan asked people to add stones to the car, and continued to walk forward, when suddenly there was a squeak, and the small train overturned. Vehicle parts are scattered all over the place. It turned out that after the rain, the deformed wheels of the wooden blocks were stuck after soaking in water, and the speed of the rear box was relatively fast, which hit the car in front of it, causing a rollover. Linjin suggested that Li Tangshan and Lu Yiqiao wooden rails should be treated with anti-corrosion and anti-deformation, the humid weather in the south, this aspect of treatment is very necessary, Linjin and the treatment method to Lu Yique and the carpenters said, Lu Yi's shortcomings nodded, and also thought it was feasible.

Li Tangshan found that he understands the theory of trains, and now in practical application, he can find that it is not as simple as the theory at all, and many details will go wrong.

Li Tangshan asked Lu Yique to change the wooden rails and vehicles, and the test continued. The test effect was very good, Gong Bing felt that Li Tangshan's wooden road was too well conceived, and Li Tangshan told them all about the working principle of the entire wooden road and how to build it. Gong Bing and the others praised the idea too ingeniously, and they were very happy, they could build a similar wooden road near Henan, where the climate and environment are more suitable for this kind of wooden road.

After the success of the test, Li Tangshan first made a wooden road from the county seat to the Nanjiang wharf. Greatly improve the efficiency of transportation.

But later it was found that as Linjin said, the humid climate in the south greatly increased the cost of using wooden roads. Later, due to the high cost and maintenance cost, Longchuan in ancient times was not supported by machining supporting industries, and the maintenance cost far exceeded the level that Longchuan County could bear. Li Tangshan could only put aside the idea of building a train, and had to switch to the traditional way of transportation with cheaper animal power, and Li Tangshan asked Lu Yique to lead the sergeants to help build a traditional post road on the basis of the original Chu Road. Later generations called this post road to the hinterland of the Central Plains as the salt road. This salt road has been used until before the reform and opening up, before the large-scale popularization of the highway, this ancient post road was called the Languan Ancient Road by later generations.

This winter, the political atmosphere in Xianyang became more and more tense, and soon it came that Qin Shi Huang ordered to "pit Confucianism". Fusu admonished and was reprimanded to the county prison army. Xianyang City was ready to start the construction of Afang Palace and Lishan Imperial Mausoleum, Gong Bing and others had to return to Xianyang City, and Li Tangshan and Lu Yique personally sent the six of them to Poyang County.
