"So that's it. Since Your Majesty wants the black stone mine, I should send it to you."

King Jin said that he would ask Yan San to get the land deed.

"Imperial brother, wait a moment."

Emperor Hongwen looked at King Jin, his eyes becoming a little complicated unconsciously.

Suddenly he said, "Has your royal brother ever complained about me?"

King Jin was startled by these sudden words, but he quickly reacted and waved to Yan San and those serving in the palace next to him to go down.

"Do I need to get out of the way?"

Lu Yaoyao asked.

"You don't have to."

Emperor Hongwen and King Jin spoke almost at the same time.

Well, she just asked casually, but she really wanted to gossip.

"Brother Imperial, if I say I have never complained, you will not believe me."

Emperor Hongwen nodded, he really didn't believe it.

"I have complained before. After all, we have been close friends since childhood. When you became the emperor, I thought I would have a backer in the future. Unfortunately, everything changed after you became the emperor."

Having said this, King Jin smiled somewhat self-deprecatingly and continued, "It turns out that you are not my backer, but on the contrary, you are the sharp blade that may take away my life."

"My brother has been very tired these years. I have to be cautious in everything. I am worried that if I go too far, I will be killed."

"So, princes have always had fiefs, but my brothers dare not ask for them, for fear that they will be like the other brothers."

When he said these words, Emperor Hongwen's eyes and heart were very complicated.

The events from back then came to mind one by one, and suddenly a feeling of guilt arose.

"I'm sorry, but I still have some gratitude to you."

"At least there is no friendship in your heart, and you did not kill my brother."

Emperor Hongwen remained silent.

It's not that he didn't think about it, he even almost executed it, but the eldest princess stopped him.

When he heard King Jin's words, the guilt in his heart became more intense. He couldn't help but think of the few warm experiences he had in the late emperor's cold palace when he was still young.

"I have wronged you."

"I understand what Your Majesty has done and thought. I don't ask Your Majesty to make amends. I just want to be like this."

Lu Yaoyao on the side just listened quietly.

Regarding these two brothers, I just had the mentality of watching the fun.

She would not comment on the authenticity of it, nor would she think about it.

After all, she had used a scan on King Jin back then and knew everything about what King Jin had done. She even knew a shocking secret.

"I have my own considerations."

"This is the first time I've come to your palace in these years. I just took a look and found that it's really a bit strange."

"I think the business Wanfu mentioned this time is very good. You can also join in. I will set a price and purchase the black stone from you."

"His Majesty."

"You don't have to say it. When you gave up your fiefdom and claimed these two black stone mines, they were yours and they will always be yours."

King Jin nodded.

"Let Wanfu explain the details."

Soon Lu Yaoyao Jiujiang explained his own plan, among which the one targeting Black Stone was separate.

She plans to invest in the black stone mine and mine the black stone together in the future. She develops technology to wash away the toxicity on the black stone and gets 20% of the profit.

"You can really remove the poison from black stone."

"Of course, otherwise what would I be doing here? Bringing His Majesty with me?"

King Jin looked at Lu Yaoyao in surprise.

This girl is really mysterious. Could it be that she has learned so much after ten years on the farm?

"Wanfu is a capable person. The emperor can let her try it first."

"If the toxicity can really be removed, this black stone will definitely replace charcoal and become a must-have for people to keep warm in winter, and the benefits will not be small."

"yes."

King Jin quickly calmed down and answered.

Immediately, he found Yan San and asked him to inform the manager at the Black Stone Mine.

Although these two mines are both within the boundaries of the capital, they are still some distance away from the capital, and it would take at least an hour or two to get back and forth.

"The steward over there probably won't come until this afternoon."

"How about when they arrive, how about I ask Yan San to take them to see the Lord Wanfu County?"

"Well, then it's Prince Lao, and I have to go back and prepare some things."

As she spoke, she looked at Emperor Hongwen.

"If you have anything to do, please step aside. I have some things to talk with Prince Jin."

Lu Yaoyao bowed and left.

She didn't want to get involved in the matter between these two people.

After leaving the Jin Palace, Lu Yaoyao got into the carriage and asked the driver to drive to the Lu family.

After having lunch there, she returned to Chengyuan Villa.

It took me two hours in the study to sort out all the theoretical knowledge required for coal washing, ironmaking, and steelmaking.

I have to say that since the universal search engine was upgraded to level 3, it has become more convenient to use.

Just merge the selected search content with itself.

Then just sort it out and copy it down.

"Miss, Yan San's bodyguard from Prince Jin's Mansion is outside asking for an audience."

"Oh, let them in."

Not long after, Yan San walked in from outside with two middle-aged men.

"I have met the Lord Wanfu County."

After Yan San saluted, the two people following him also saluted quickly.

"County Master, these two are the stewards of the Black Stone Mine. Your Majesty has told me that they will follow you from now on. You can ask them to do whatever you need or do."

"Okay, thank your prince for me."

Yan San cupped his hands, then turned around and told the two of them: "From now on, you will follow Wanfu County Master, and remember not to neglect, otherwise the prince will blame you, and you will know the consequences."

"Don't worry, Mr. Yan San. I will definitely obey the arrangements of Wanfu County Lord and will never be negligent."

After receiving their answers, Yan San nodded with satisfaction, cupped his hands to Lu Yaoyao, then left and turned around.

As soon as he left, Lu Yaoyao took out the method of washing coal and gave it to Qiu Shuang and asked her to hand it over to the two of them.

"This is the method I compiled to remove the toxicity of black stone. Some of the things in it are not ready yet. You can build some facilities first. When I have the things ready in a few days, I will go to the black stone mine in person."

"yes."

The two of them responded and looked down at the things in their hands.

After a while, Lu Yaoyao asked, "Is there anything you don't understand?"

"No."

We just asked them to prepare the venue and some tools, and they didn’t need any technical content. How could they not understand this?

"Then you go back and prepare first. I will go to the Black Stone Mine in person in five days."

The two of them bowed in response and then left.

After the two left, Lu Yaoyao stretched and stood up.

"I'm a little hungry. Qiu Yu asked the kitchen to prepare some food."

While eating, she was still thinking about some future plans.

Now that coal has been found, we will soon prepare to make iron and steel. Washing coal is easy, but making iron and steel is not easy.
