The news of Zheng Fu's death diluted the joy of the New Year's Day in the champion Houfu, Zheng Peng canceled many celebrations, that is, the annual Shangyuan Festival, and simply hung a few self-made lanterns led by Lin Xun'er and the maidservants in the house at the door.

After the Shangyuan Festival, Li Longji issued an order to restore Zheng Peng's position as the Weapons Supervisor, mainly to facilitate Zheng Peng to lead the work of the Firearms Administration, but there was no way, the Firearms Department was without Zheng Peng, and the progress was obviously lagging behind.

In addition to abandoning the curve and straightening, digging holes, filling ditches and building bridges, this project is a big project in later generations, in the Tang Dynasty without technology and large machinery, the difficulties can be imagined, Zheng Peng almost lived and ate with the craftsman on the construction site, and solved a problem when he encountered a problem, leading a group of craftsmen to find ways to solve it one by one.

In addition to building roads, Zheng Peng also had to be distracted from taking care of Wangniudun and Changluo Headquarters.

The main task of Wangniudun is to prepare for the iron needed to repair the railway, especially the high-strength iron, more than ten furnaces are not extinguished day and night, continuous improvement, demonstration, and the production of iron is getting better and better, the most surprising thing for Zheng Peng is that An Lushan is really doing a fine line, let him mix in Wangniudun for two years, he is untaught, looking at the tinkering, has become an excellent blacksmith, it is said that he likes to pick up a big hammer of more than fifty catties, a hammer is most of the day, in his words, to pass the time, you can also lose weight, You must know that An Lushan can eat too much, and will enjoy it, his weight has long exceeded 200 catties, and he trembles when he walks, just like a person walking upright... The big sow, in the end, even he himself dislikes himself.

Changluo Command is mainly responsible for the drawings of the line, and then the rails and trains, under the guidance of Zheng Peng, the style of the rails and the model of the train have long been done, and now the main research is how to drive the train, in addition to manpower and animal power, the craftsmen of the Changluo Command have been committed to studying Zheng Peng's proposal to push the steam, I have to admire the wisdom of the ancients, their execution and innovative spirit, sometimes Zheng Peng is also moved.

Everything is going in a good direction.

When a person focuses on one thing, he always feels that time flies very quickly, and before he knows it, he has reached the twenty-fifth year of Kaiyuan.

On the 17th of June, in a place called Dashaping in Xingxian County, Puzhou, suddenly thunderous applause, cheers shook the sky, thousands of people cheered and jumped unwillingly, many people hugged and jumped together, the scene was very lively, many people shouted loudly on the spot:

"It's over, it's finally done."

"Five years, five years of repair, finally completed, it's not easy."

"I can't believe that the young master has really succeeded, I can't believe it."

"The champion is really amazing, he has built such a long road by himself."

"In the past five years, tired horses can fill deep ditches, waste tools can be piled up into mountains, and spent money can be scattered all over the sea."

"That is, the Firearms Department can't remember how many times it has been tested for explosions, only the champion has this ability, no matter what, I must have a good drink today."

On the construction site, whether it is a craftsman, an overseer or a slave, their faces are filled with happy and proud smiles, because the Changluo Road, which has been repaired for five years, has finally been completed.

Zheng Peng, who was standing on a big rock, looked at the straight, flat, and unsightly road, swung his fist hard, and said with some excitement: "Finally, the project was successfully completed, and the past five years have not been in vain, which is great." ”

Fang Bin on the side congratulated: "This road can be built so quickly, it all depends on the young master's efforts to maintain it, without the young master, there will be no Changluo straight road." ”

In the course of road construction, asking for money, asking for money, asking for money, Zheng Peng didn't have a word, as much as possible, when the funds were the most tight, the accommodation conditions of the craftsmen and slaves never declined, there were meat dishes, and they could drink a few glasses of mellow wine during the New Year's holidays, and they behaved well and served with maidservants, and the people below all seemed to be doing their best, Fang Bin felt his little hands tremble at the beginning of holding 10,000 or thousands of guan, and then he often had 100,000 guan and hundreds of thousands, so that now he has no concept of money.

I can't count how much money has been spent since the start of construction, anyway, there are many, many, many things, fortunately, my young master is rich and has a good way to make money, otherwise I really can't support it.

Zheng Peng waved his hand and said, "Fast?" It's not fast, you must know that Qin Zhidao has only been cultivating for two years. ”

In the 35th year of Qin Shi Huang (212 BC), Qin Shi Huang ordered the construction of a road leading to Jiuyuan County from Yunyang, named Qin Zhidao, with a total length of more than 700 kilometers. There are many theories about the purpose of building the Qin Straight Road, among which the more popular sayings include "for the convenience of patrolling", "as a passage for transporting troops" and "as a traffic line", etc., the most accepted by later generations is that it is to defend the Hu people from going south, the project is built by Meng Tian, the project is very huge, but the construction period only took two years to complete, which can be called a miracle.

Lao Qi said with a smile: "Young master, you can't compare like this, Qin Shi Huang is the emperor, an order, Bafang Yuncong, can mobilize hundreds of thousands of people to build the road at once, what do you want, it is already very powerful to be repaired in five years, and Qin Zhidao said that it was completed in two years, but in fact, there are still major repairs and small repairs in the back, and the historical records say that when Meng Tian was given to die in the 37th year of Qin Shi Huang (210 BC), Qin Zhidao has not yet been completely repaired. After Qin II ascended the throne, he continued to build the Qin Straight Road, and he could not be fully trusted. ”

Zheng Peng waved his hand and said, "Forget it, don't talk about this, everyone has worked hard all these years, and we must celebrate tonight." ”

Qin Shi Huang can mobilize hundreds of thousands of people, but the technology and tools of the Tang Dynasty are more advanced, Zheng Peng also used gunpowder blasting, which saves a lot of manpower, which is one of them; The second is the Qin Straight Road built by Qin Shi Huang, which is built in the barren mountains and mountains, and the transportation is very inconvenient, unlike the Changluo Road, the traffic is profitable, and sometimes the canal can be used, and it is convenient to move and transport any materials; The last point is the scale, the largest place of Qinzhi Road is sixty meters wide, and the narrowest place is also twenty meters, which is much more spectacular than Changluo Road, but there are many confused accounts in history, the language is unknown, the memory is simple, and many details are brushed aside, and they can't be compared at all.

I don't bother to compare.

Ah Cai on the side rubbed his hands and said with an expectant face: "Everyone has already said this to the young master." ”

When the people present heard this, they all had smiles on their faces, and they were not surprised by Zheng Peng's generosity and boldness, ordinary meals are meat and vegetables, and adding vegetables is wine and meat, as for celebrating well, it will definitely not disappoint.

Zheng Peng looked left and right, pointed to An Lushan who came to watch and said: "An fatty, this matter will be left to you, you must make it lively tonight, if someone says that you are not satisfied, you are the only one who asks." ”

Today is the first phase of the completion ceremony of Changluo Road, as one of the heroes, An Lushan also came here to watch the ceremony, Zheng Peng knew that An Lushan was careful and thoughtful, and the most important thing was to know what those craftsmen and slaves liked, and it was definitely right to hand it over to him.

"The owner can rest assured, everything is wrapped up in the small one, and it is guaranteed to satisfy everyone." Unexpectedly, such an important task fell on him, An Lushan was shocked at first, but quickly accepted the task.
