The Sanshuren incident ended, and Li Linfu was also given "eye medicine", Zheng Peng instructed Lu Shu and Lin Xun'er to stay at home, and then hurriedly went to the Changluo Headquarters in Puzhou again.

Li Ying's death is not the end, but the beginning of another struggle for the prince, after Li Longji deposed Li Ying, he did not adopt Li Linfu's recommendation, and Li Mao, the king of longevity, was the crown prince, but suspended the position of the prince, so that the new prince was a dragon and tiger fight, Zheng Peng took the opportunity to withdraw and put himself outside the whirlpool of the struggle.

Lu Shu and Lin Xun'er are not people who provoke right and wrong, and with Cui Yuan taking care of them, Zheng Peng can go with peace of mind.

Of course, it is also a new beginning for Zheng Peng, the dirt road in Changluo was successfully opened, this is not Zheng Peng's goal, the flat dirt road is just the foundation, what Zheng Peng wants to do is to build the first railroad in Datang.

When Zheng Peng came to the headquarters, he saw many people busy on the construction site from a distance, and it was Lu Ping, the head of the Sanbao Process R&D Department, who took the lead.

Lu Ping is also the head of the Changluo Command.

Outside the headquarters, a three-mile-long railway track has been paved, and at the beginning of the tracks, a simplified train about seven feet high and more than four feet long lies quietly on it, but it is only a frame, and many craftsmen are debugging and renovating the train.

"Get the nails right, don't turn them upside down."

"The upper seat is reinforced again, and in the future, there will be people sitting on it, and if you fall, it will be a great sin."

"Paint the power room again, and soon install the steamer."

"The infrastructure team will check the rails again, pay attention to whether there are any loose or rusty problems, the young master will come to inspect soon, and the young master can't be disappointed."

Lu Ping, as the commander-in-chief, gave orders while inspecting, and when he was busy, the apprentice next to him, Zhuang San, whispered: "Master, young master, young master is here." ”

Hearing that the young master was coming, Lu Ping turned his head to see that it was Zheng Peng, who was really studying the railroad tracks, and hurriedly ran over to salute: "The little one has seen the young master, but I don't know that the young master has arrived, and I am not far away." ”

Zheng Peng waved his hand and said, "Excuse me, Lu Ping, you came just in time, have you tried this section of railroad?" ”

"Back to the young master, I have tested it many times, and I have tested items such as load-bearing, cold and heat resistance, deformation, rust, etc., and the effect is good." Lu Ping said respectfully.

Before the iron was transported from Wangniudun to here, there were requirements in all aspects, and it had been tested many times before it was laid after it was transported to the headquarters, and Lu Ping immediately began to lay a three-mile-long railway track for testing, and the Changluo headquarters was located on the side of the Changluo road, so that the rails laid were not wasted.

"Has it been tested for load-bearing?" Zheng Peng immediately asked about the key elements.

The rails have to bear the weight of the train, which is not small, if the load-bearing capacity is not up to standard, and it will deform as soon as it is pressed, then everything is empty talk.

"After testing, all the heavy stones were put on the train, four carriages, and the weight of 3,000 stones was still safe and sound, and the load-bearing was not a problem, and now it is rust-proof." Lu Ping explained: "The iron has been forged and tested many times when looking at the cow pier, and the process department has adjusted a new lacquer, which is applied to the rails to prevent rust, because the time invested is still short, the effect is not clear for the time being, but the small ones have been marked and measured in sections, and they will be observed and recorded every once in a while, and the results will be handed over to the young master to check at that time." ”

Zheng Peng nodded when he heard the words and said: "Do a good job, continue to work hard, what we have to do now is to keep picking out our own faults and shortcomings, now pick them out by ourselves, and correct them in time, if you let the guests pick them out when they are put into use, then what you lose is the face of this young master, understand?" ”

In addition to the cost of land acquisition and road construction, Wangniudun spends money like running water, in order to get high-quality iron, in addition to hiring skilled blacksmiths with high salaries, more than a dozen blast furnaces are working day and night, constantly testing different formulas, not to mention anything else, Zheng Yongye, who contracted Wangniudun coal transportation, that is, the cousin of Zheng Yongyang of Xingyang Zheng's family, made a lot of money by relying on Wangniudun, and accepted the seventh concubine in less than three years.

Finally, there is a return on the pay, and the load-bearing 3,000 stone can still be used normally, which is a very good test result, you must know that a stone in the Tang Dynasty is equivalent to 53 kilograms in later generations, and the load is about 150 tons, which is nothing in the later generations, but in the Tang Dynasty, which is relatively backward in science and technology, it is already very remarkable.

Of course, for the sake of safety, these rails are also much thicker and heavier than the obvious ones of later generations, which is considered to be of insufficient quality.

Don't worry about the moth-proof sleepers of the rails, the Chinese people have a love for wood from the bottom of their bones, and have summarized a set of anti-moth methods early, Zheng Peng wanted to remind Lu Ping to pay attention to the anti-rust work of the rails, thinking that Lu Ping had already planned to make a new paint to prevent rust on the rails, and thought very thoughtfully.

"Understood, young master." Lu Ping said respectfully.

For Zheng Peng, Lu Ping admires from the bottom of his heart, the young master seems to be not very old, but he has a whimsical idea, not only dares to think, but also dares to do, the most important thing is this ability to do, for craftsmen who rely on craftsmanship to eat, it is to admire this kind of person with real talent and learning.

Zheng Peng pointed to the craftsman who transformed the train and said, "It seems that you are ready to measure?" ”

"The young master is wise, he is almost prepared in all aspects, he can't just think about it, and it is ideal to improve while testing."

Zheng Peng's heart moved, and he couldn't help but ask, "??" A new breakthrough in the steam engine? ”

The core of the train, and Zheng Peng's most important, is the driving problem, Changluo Road has not yet been requisitioned, Changluo Command has begun to build, for this reason did not hesitate to draw a large number of excellent craftsmen from the Sanbao, mainly Zheng Peng put forward the idea, and then according to the memories to draw a general pattern and research direction, Zheng Peng's idea is to first use manpower, animal power and steaming thrust to push together, and then put into use, while continuing to research, until it can be fully pushed by steaming.

Hearing that Lu Ping was going to conduct a measurement, I believed that there was a breakthrough in steaming.

Lu Ping said excitedly: "The young master is too powerful, the small one is to test according to the young master's ideas and prompts, I have to say, at the beginning, I couldn't do anything well, mainly because the air leakage was too serious, to put it simply, it was like a wind instrument, it would only blow a wind, and after the improvement, you can do some small things, such as fetching water, pushing a stone mill or something, and it will not work if it is a little heavier, but fortunately, I thought of a way later." ”

"What's the solution?" Zheng Peng suddenly became interested.

The steamer needs to use rubber as a seal, but at this time Datang does not have such a thing as rubber, to get rubber, to get distant South America, with the current navigation ability, it is too difficult, Zheng Peng hinted that Lu Ping to find some alternatives, anyway, the direction is pointed out, and the rest has to be solved by himself.

Lu Ping, who was careful and cautious, suddenly transformed the train and said that he was going to enter the actual test, indicating that he had made a major breakthrough in steaming.
