The abandoned wife married into a wealthy family, and the scumbag father wailed every night

Xie Yiyao didn't care about the carnival in Yanjing City. She was concentrating on the design of the coal mine drawings.

She referred to several versions of blueprints for deep coal mine operations, scribbled and drew until late at night, and asked the magic doctor system to analyze and evaluate her several times before finally finalizing the coal excavation blueprint that best suited the terrain and mining characteristics of Yanjing.

I looked at the hourglass and it was already midnight!

Xie Yiyao rubbed her shoulders and arms, muttering to herself, "This is such a fucking inhuman job, I'm so exhausted!"

Maybe it was because she had passed the sleepy point, or maybe it was because she had already drawn energy into her body and she didn't seem to need too much sleep.

Xie Yiyao lay in bed unable to sleep, so she began to think about her future plans.

Feng Junqi and Su Yunyi should have arrived in Gucheng by now. According to the personalities of the male and female protagonists, they will start a war sooner or later, but they absolutely do not want to be involved in a war.

Therefore, she had to build the city of Yanjing into an impregnable one, and she also had to absorb as many people from other places as possible to migrate to Yanjing. This would not only gather manpower and increase the city's strength in numbers, but also increase its ability to fight against war.

Second, the construction of Yanjing City requires a large amount of labor. This Yanjing City is too desolate, and there are many things to do. The more labor, the better!

But the most important things now are coal mining, sweet potato planting, and cotton. We must proceed step by step and don't be in a hurry!

The next morning.

Xie Yiyao followed Gu Yubai and Gu Yu'an to Xishan Coal Mine. Of course, "Feng Junyi" also followed with a noble and expressionless face.

Zhang Zhongdan still had an instinctive awe for this serious prince.

Although he was full of gratitude towards "Feng Junyi" in his heart, he even wished he could die for Feng Junyi immediately!

But looking at the noble and indifferent "Feng Junyi", he still didn't dare to approach and talk to him, but just carefully reported the progress of the past two days.

After hearing this, "Feng Junyi" turned around and looked at Xie Yiyao!

Xie Yiyao naturally handed the blueprint that she had drawn last night to Zhang Zhongdan.

"In the future, you will dig in the underground mine according to the method on this drawing."

Zhang Zhong took the drawing from Xie Yiyao with some hesitation, and was a little confused:

"What are these pillars for, Princess?"

"It's used to stabilize the mine so that it doesn't collapse."

Xie Yiyao explained patiently.

"Then what are these holes used for?"

Zhang Zhongdan still looked curious.

"It's used for ventilation to prevent the miners from being poisoned."

Xie Yiyao continued to explain patiently.

"Ah, so coal is poisonous?!"

Zhang Zhongdan was shocked!

"Then why do you think I asked you to recruit coal washers?"

Xie Yiyao looked very amused. This Zhang Zhongdan was really a brave man!

Zhang Zhongdan's face turned slightly red, but he couldn't help but speak:

"This railroad track does seem to save time and effort, but we don't have iron!"

Xie Yiyao looked at Zhang Zhongdan with sympathy. The mayor of Yanjing City was begging with a golden bowl in his hand!

He has been managing Yanjing City for so many years, so it would be fine if he didn't know about the coal mine. After all, no one in the current Deng has ever seen what coal looks like, so even if he has seen it, he may not recognize it.

However, this old Deng didn’t even discover the most scarce iron mine in their Great Deng!

Oh my God! She remembered that the history books recorded that there were 9.5 million tons of iron ore in Miyun District, the capital of China!

Hey! Xie Yiyao sighed and looked at Zhang Zhongdan and said:

"Master Zhang, take your men to the northeast and dig a lot at the junction of a mountain range and a plain!"

Zhang Zhongdan was shocked. How come our Zhang family has lived in Yanjing for generations and we didn't know there was an iron mine there? !

"So, this kingdom belongs to the Feng family!"

Xie Yiyao looked at Zhang Zhongdan with a teasing look on her face.

After saying this, she glanced at "Feng Junyi", clearly conveying that it was Feng Junyi who told her the news.

Xie Yiyao didn't feel embarrassed at all when she lied. Anyway, all the benefits went to Feng Junyi, so it was reasonable for him to take the blame!

Zhang Zhongdan looked at "Feng Junyi" with admiration:

"The prince is indeed a man blessed with great fortune and blessings!"

Xie Yiyao gave Zhang Zhongdan a thumbs up in admiration:

"Your Excellency is indeed from a family that has been in politics for generations. Your flattery skills are simply perfect!"

Zhang Zhongdan felt a little embarrassed.

Hehe, isn’t flattery an important skill for officials in our country?

He practices hard and imitates every day to improve his business ability in this area!

If you flatter well, promotion is inevitable.

"Crown Princess, but if this happens, I'm afraid we won't have enough manpower in Yanjing City!"

After his excitement, Zhang Zhongdan looked at Xie Yiyao with some concern and said.

"I have sent people to post notices in various places. All the people who are willing to move to Yanjing can sign up for work-for-relief and can also be allocated land."

Xie Yiyao had already thought of a countermeasure, but Zhang Zhongdan still had a bitter face after hearing it:

"Apart from the wasteland, we in Yanjing have nothing to share with the people who migrate here!"

Xie Yiyao: "Which place in the country is not a wasteland now? At least in Yanjing City, there is enough water and I can work to support my family."

"Besides, who is my uncle? We can also promote his recipe for improving soil in Yanjing City!"

Zhang Zhongdan Wenyan immediately smiled happily.

Yes! The whole country is suffering from the cold weather now, and no one is better off than anyone else.

Thanks to the prince, their city of Yanjing has both food and water. Only a fool would not come.

Zhang Zhongdan was so excited that his soul left his body. His Zhang family was going to become rich!

He had a hunch that as long as he followed the Crown Prince and the Crown Princess wholeheartedly, the Zhang family would definitely become a prominent family in Da Deng!

Oh my God, Zhang Zhongdan is truly the pride of his ancestors!

Zu Wen of their Zhang family finally survived thanks to Zhang Zhongdan's efforts!

Xie Yiyao had no idea that this seemingly intelligent man was actually a brainiac. She turned around to check whether the miners' operations were in compliance with regulations.

She was still a little worried. If these miners did not dig coal according to the method she had specified before, accidents would definitely happen.

After a round of investigation, she was relieved to find that these miners were very obedient.

Zhang Zhongdan carried out her requirements very thoroughly, and every miner's movements were very standard.

According to this mining schedule, her drawings will be ready in just one week. By then, with some rails and trains, the coal mining speed will be even faster!

After visiting the coal mining area, Xie Yiyao went to the coal washing area. The coal washing area looked a little more modern.

There are several large coal crushers working non-stop, and the coal washers are waving their tools non-stop, and each of them looks like they have endless energy!

When Gu Yubai saw Xie Yiyao coming, he ran over happily. He had always been puzzled as to why his niece asked someone to wash the black coal when there was such a water shortage.

Now that I have the chance, I must get to the bottom of it.

"Girl, why do we need to wash the coal?"
