Lu Ning sent Xie Jin to take over these mines, anyway, since it is the right to use it for half a year, then it can be used vigorously.

After all the formalities were completed, Lu Ning came to these mines to start exploring.

However, it was accidentally discovered that there is a large amount of Yanchuan stone liquid and natural gas stored here.

Needless to say, Yanchuan stone liquid is a natural treasure, which can be used to refine asphalt and oil for road construction and as a power for cars.

And natural gas, as a precious raw material granted by nature, is of course very rare.

Lu Ning knew that since this thing had already been discovered, it must be stabilized from the legal level, lest anyone make any more moths.

Thinking of this, he still felt that it would be better for him to go back to Yingtianfu first and settle things.

So, he let a few apprentices sit here, and he quickly returned to Yingtianfu.

After coming back. He first went to the harem to meet Queen Ma, the kind aunt, and then went to the Qinzheng Palace to see Zhu Yuanzhang.

Seeing that Lu Ning's body was getting thinner and thinner during the time he was in Beiping, Zhu Yuanzhang was also very distressed, so he said.

"Some things don't have to be done personally, just let the subordinates do it, and besides, you still have three apprentices, and let them go through the experience, you may not do everything yourself."

Lu Ning nodded, and then said to Zhu Yuanzhang.

"Uncle is a heart of concern, my heart is very warm, please rest assured, I will not tire myself out, this time I came back to discuss with you urgently."

After finishing speaking, he put his own memorabilia and the topographic map of the relevant mines on Zhu Yuanzhang's bookcase, and then said.

"The little nephew has discovered several mines in Beiping, and there are a large number of Yanchuan stone liquids and natural gas reserves, which are all natural treasures and have great use."

Zhu Yuanzhang already knew what this Yanchuan stone liquid was, but he didn't know much about natural gas.

"Zi'an came to tell us, what is this natural gas? Isn't it also very valuable? ”

Lu Ning explained the role of natural gas to Zhu Yuanzhang, and then told him.

"Originally, I thought of using the steam engine as the power to use radiators for all the people in Beiping, but if there is natural gas, it will be more convenient, and only one pipeline is needed, and the whole of Peking can be unified for heating."

Although Zhu Yuanzhang listened to the clouds, he didn't know much about these principles.

But he understands very well that as long as there is natural gas, the people of Peking will be able to live a life without worrying about winter.

Zhu Yuanzhang was an emperor from a poor background, so he was naturally very concerned about the people, so he said immediately.

"What Zi'an means, do you want us to hand over all the rights to use and exploit this natural gas to you, and then you will benefit the people!"

Lu Ning immediately gave Zhu Yuanzhang a thumbs up from his heart, worthy of being Emperor Hongwu, this comprehension ability is not ordinarily strong.

"What you said is right, but this is not to give me all these minerals, just to give me the right to use them, now these things are all from the domestic department, do you still want to say hello to the fourth brother?"

In fact, Lu Ning knew very well in his heart that although he wanted to benefit the people, he must not touch the cake of these princes.

After all, these people are Zhu Yuanzhang's own sons, and his own righteous nephew can be sacrificed at any time at a critical moment.

Lu Ning knows this best, so he must not offend any prince.

Zhu Yuanzhang didn't think about it so much, he told Lu Ning directly.

"Don't bother so much, just say hello to your fourth brother, just say it's what we said! All the mines in Beiping, whether it is the right to use or the right to exploit, are all under your control. ”

Lu Ning was also a little helpless, he originally thought that he would let Zhu Yuanzhang come forward to say this, and he would not offend Zhu Di, so it seemed that he had to go to Yanwang's Mansion in person.

After he entered Zhu Di's mansion, the two exchanged pleasantries again, and finally Zhu Di asked Lu Ning about his intention.

Lu Ning said about the mining of the mine, and then said helplessly.

"Originally, this was the errand of the Fourth Brother's Domestic Products Division, and I really couldn't interfere more, but others don't know much about natural gas, so for the sake of safety, I can only reluctantly make it difficult, please don't be more careful with the Fourth Brother."

With all that said, what else can Zhu Di say? He had no choice but to reply.

"Zi'an thinks too much, you and I are brothers, how can the fourth brother account for those things, and besides, you are for the benefit of the people of Beiping, so naturally you will also leave a good reputation for me, I have to thank you."

After finishing speaking, Zhu Di ordered a banquet to entertain Lu Ning and talk about brotherhood.

But this meal, Lu Ning was indeed a little tasteless, he knew that this was just a show on the spot, how could there be family affection in the heavenly family.

After estimating and eating, Lu Ning quickly returned to Beiping, and then handed over all the design drawings to Fu Bo and the three apprentices.

Lu Ning told them that they should install all the radiators of all the people in Beiping as soon as possible, and they were not allowed to collect a penny.

Then all the pipelines were erected and all the natural gas was connected.

All of a sudden, all the people in Beiping City used radiators for heating, and the degree of warmth was much stronger than that of burning coal.

The use of natural gas has long been popularized, and the people of Beiping regard Lu Ning as a living bodhisattva who saves suffering.

Some people even offered Lu Ning's immortal tablet at home, and visited the province in the morning and dusk.

At the same time, it has also brought a new effect, that is, with free natural gas and radiators, coal is no longer so important.
