"Your Highness, you are back!"

Seeing the Queen Mother Xiaozheng, Wu Meiniang hurriedly got up and ran over excitedly.

"When did you come?"

Xiao Zheng was a little confused. What did these two guys come here to do? How could their news be so well-informed?

"Your Highness, you have been doing so for so long, and you have not made any moves. Chumo and I are very anxious. Even if we are helping you address the construction academy, or helping you recruit students, at least we have the value of existence, don't you?"

Qin Huaiyu took the lead and leaned over with a thick face. He said so beautifully, and ignored Wu Meiniang and Li Yan'er's little contemptuous eyes.

"Did you remember what the prince discussed with his father a few days ago?"

After hearing his words, Xiao Zhengtai suddenly understood what was going on. There was no one of the two guys who was at peace. They hadn't taken them to play for a while, and their hearts had long been restless.

"What Your Highness is talking about is that Lao Shi steam engine?"

Cheng Chumo asked uncertainly, this is the only thing I heard in Xuanzheng Hall before.

"Not bad! The steam engine has been developed. There is a lack of an experiment place now. What you need to do in the next period of time is to build a railway. Do you still remember the route marked by this prince on Dongshan when he went out for a trip last time?"

A wicked smile appeared on Xiao Zhengta's cheek, and she directly assigned tasks to the two of them. Isn't it so painful to have a free time? Then go over and make some changes.

"Your Highness, please tell me carefully, how should you do that thing?"

Hearing that there was a task, Cheng Chumo's eyes suddenly lit up, and he hurriedly approached the front and asked with great enthusiasm.

"This is……"

When he saw Xiao Zhengtai taking out the drawings again and looking at the lines marked with cinnabar, Qin Huaiyu took a breath. If the railway was paved according to the records on the drawings, with the power of the two of them, it would be paved until the Year of the Monkey and Horse Month.

"You just need to lay the rails along the mountains and extend them here for experiments."

Seeing the two of them being scared, Xiao Zhengtai hurriedly made her request. Otherwise, it would be too difficult to complete these projects with the resources they could call.

"Yes! Let's do it now!"

Cheng Chumo had never had any resistance to work, so he quickly agreed. He knew that the task assigned by His Highness was definitely not an easy task.

"Your Highness, what is the experiment you just mentioned?"

After the two left, Wu Meiniang asked embarrassedly. As the person around His Highness, she couldn't understand what His Highness was saying. This was her dereliction of duty.

"It's just a means of transportation. When the research and experiment is successful, I will take you over and take a look."

Looking at her curiosity-seeking face, Xiao Zhengta laughed and explained briefly that she would not have any rest time in the near future.

"good!"

After hearing His Highness's words, the two women suddenly felt happy and nodded quickly to agree.

In the following days, Xiao Zhengtai kept running around the Changsun Mansion and the East Palace every day. The plan was ahead of schedule, which forced him to focus on the research on trains.

Changsun Wuji, who was doing his best, did not disappoint Xiao Zhengtai. In less than a month, the entire locomotive parts manufacturing was completely completed.

However, Xiao Zhengtai denied the suggestion of assembling directly at Changsun’s house, and summoned people and carriages to transport the parts to Dongshan in batches.

This thing can be made of steel. If it is assembled at Changsun’s house, even if it is successful in the end, it will not be transported to the railway tracks on Dongshan, so the best place for assembly is Dongshan.

"Your Highness, is this what you are talking about in the train? Can it really run so fast?"

Looking at the craftsmen and constantly assembled the parts one by one according to the drawings. Cheng Chumo's eyes were straightened.

"Well, how far have the railroad tracks been laid out?"

He nodded slightly to respond to Cheng Chumo's question. After the assembly is completed, he will start the experiment.

"Your Highness, because everyone has done such a job for the first time, the progress is not very fast. It took nearly a month and it has been less than a thousand meters."

Cheng Chumo was very embarrassed. He was in front of His Highness and took on a lot of things. During this period, even though they worked overtime in black and white, they had only done these jobs, which made Cheng Chumo feel very guilty.

"Your Highness, you came so early!"

At this moment, Changsun Chong walked over quickly and saw the Queen Mother Xiao, hurriedly stepped forward and bowed.

"You are not a young master in Changsun's Mansion, why are you going here to do?"

Cheng Chumo looked at him with a contemptuous look. In the past, there were often conflicts between them. It goes without saying that their relationships were not pleasing to anyone.

"The steam engine is a masterpiece of the Changsun family. The first time I tried it, I naturally have to come and visit it. It's you, you, if you don't go to work, what's the point of being lazy here?"

After Changsun Chong snorted, he said sarcastically that he had a legitimate reason here and was shameless to not be ashamed of others.

After contacting this period of time, Changsun Chong regretted his original attitude. His cousin was not a normal person at all. Being an enemy of him was simply making him feel uncomfortable.

What I heard about in the past few years made Changsun Chong feel very uneasy, for fear that Xiao Zhengtai would bring up old accounts. Fortunately, His Royal Highness was generous and did not mention the past.

When the steam engine was released, Changsun Chong was completely convinced by Xiao Zhengtai. As a smelting inheritance family, they didn't know that steel could be used like this, which completely subverted their old-fashioned thinking.

"You know a hammer, Your Highness promised me that I and Huaiyu will follow me during the experiment."

Through Changsun Chong's attitude at this time, it is not difficult for Cheng Chumo to see that this kid has the intention to please His Highness. A mere latecomer would not be able to shake his relationship with His Highness. Cheng Chumo was quite unscrupulous.

Changsun Chong was not concerned about this and came forward to watch the assembly situation in person. He was very interested in this new thing. As long as this experiment was successful, the future development of the Changsun family can be imagined.

"Your Highness, the assembly is almost done, you have a look!"

Changsun Chong carefully wrote down every operation process of these craftsmen, and secretly made up his mind that after returning, he must study the so-called steam engine carefully.

"Um!"

Xiao Zhengtai hurried forward to check it out, not daring to miss every detail. After all, this was the first time that the Tang Dynasty appeared, and it also concerns life issues. There is no need to be careless at all.

"Your Highness, how can this thing run? When will we start the experiment?"

Cheng Chumo also ran over and looked at the front of the car carefully. The shock in his heart was endless. If Xiao Zhengtai was not here, he would have run up as soon as possible.
Chapter completed!
