Chen Xu's master and apprentice said that they could make the kang in one day, but in fact, only half a day had passed, and someone reported the results to Princess Jinyang.

"That's done?" Princess Jinyang was a little surprised.

Jin Yan told her the principle of the fire kang, "This is not as simple as papermaking, the process is simple, and making it so quickly is the level that the ink artist should have." ”

Princess Jinyang smiled dotingly, and immediately instructed Zhang An, "Pass the word overnight, let the officials from all over the country send people as soon as possible, if there is a delay, the palace will ask them." ”

After Zhang An went down, Princess Jinyang sighed, "I hope I can save more people." ”

Looking at Princess Jinyang's frowning face, Jin Yan felt very uncomfortable, and when he returned to the bedroom and fell asleep, Jin Yan called 288.

Since the last world, 288 has disappeared.

Jin Yan didn't expect that little thing to suddenly jump out, just as she didn't believe the information that her father was a villain presented in the system database, she was also skeptical and defensive about 288.

The plot is fake, the information is fake, even my father and her are fake, and the existence of 288 is more and more suspicious.

Only this time, 288 turned out to appear very quickly.

"Host."

288's voice was very well-behaved, like that of a child who had made a mistake.

Jin Yan: "Are you going to untie me?" ”

288 shook his head repeatedly, "How could the host think that?" ”

Jin Yan asked again: "Then what did you do when you suddenly disappeared after the end of the world?" Could it be that I met an old friend and reminisced about the past? ”

Listening to Jin Yan's calm tone, 288 inexplicably felt a little scared, and it explained: "Host, it's not that I have disappeared, it's that there is an enchantment in the Xianxia world that keeps me out. ”

The world didn't set restrictions on it, but it was worried that Jin Yan didn't want its system anymore, so it didn't dare to take the initiative to show up.

Jin Yan chuckled, "Really? ”

288 nodded heavily, "That's it!" ”

Jin Yan: "I thought that you would be happy to see your creator when you found your true master." ”

288：“……”

You can't say that, can you?

Although it did have some doubts when it saw another "Huo Jinyan" at that time, it finally recognized the real host!

Jin Yan: "Although you have hidden many things from me, you have been unfaithful to me......"

"Host, I'm absolutely honest with you! What you think I am hiding from you is that the content shown in the system information has misled me, and my loyalty to the host can be seen by heaven and earth! 288 said hurriedly.

Jin Yan smiled, "What are you anxious about?" ”

288：“……”

If you're not in a hurry, won't you be beaten as a traitor?

Falling into the hands of the villain father and daughter, will it still have a life?

Jin Yan: "Although you are useless, it is better than nothing, now, you can use your detection function to find all the coal mines in the Northland." ”

288 was stunned, that's it?

The host finally summoned it once, and it was for this?

As if seeing its thoughts, Jin Yan said: "If it weren't for the urgency of the situation, and I was too young to travel long distances, I would have brought someone from the Kanyu family to find out the coal mine myself." ”

288 heard what Jin Yan meant.

But Fan Jinyan has no heart disease, but if she is a little older, then what she is looking for is not a person with a sense of existence "better than nothing", but a person who really has a real study of geography and landforms.

Alas.

Why is that!

288 shed tears for his relationship with Jin Yan, and then said with a firm look in his eyes: "Don't worry, host, I'm not like them, I don't need to be there, I can find out all the coal mines." ”

However, while scanning the Northland with the help of the system program, 288 discovers something terrible.

Boy.

What's that swarthy?

The Northland is literally a city built on top of the coal mine!

Expand the range and continue scanning.

288 was stunned.

Gold, silver, copper, iron, zinc, nickel, lead, selenium......

Isn't the mineral resources here a little too rich?

When 288 told Jin Yan the result with a surprised face, he found that Jin Yan was not surprised at all.

Historically, the northern part of the country was already rich in mineral resources.

And the current territory of the Northland almost encompasses these resource-rich places.

In the future, the entire land west of the river will be knocked down, and all the oil and gas will be in the pockets of the north.

It's just that.

The current level of productivity is too low, and mining and transportation are big problems, so these resources will not be used in the short term.

Of course!

This is on the premise that the land west of the river has been defeated.

Jin Yan got the location of the mineral, and immediately got up and got out of bed, and when she moved, the maid guarding the bed was startled.

"Lord Weng ......"

"I want to see my grandmother."

As soon as Jin Yan spoke, the maid immediately picked up the fox fur and wrapped her, picked her up and went to Princess Jinyang's bedroom.

The movement of the servants here had already alarmed Zhang An and the others, and Princess Jinyang had already gotten the news and stood at the door waiting.

"What's wrong?"

She took Jin Yan over, hugged her in her arms, and asked worriedly, "But what kind of nightmare is it?" ”

Jin Yan shook his head, "Mother, it's not a nightmare, it's a dream of the gods!" ”

As soon as she heard this, Princess Jinyang had not yet commanded, Zhang An had already retreated from everyone, and he himself was blocking the door of the main hall.

After only the mother and daughter were left in the palace, Jin Yan asked Princess Jinyang to carry her to the side room, where there was a large map on the wall.

Over the years, whenever they set out on an expedition, the king of the Northland would record the topography and local conditions of the places they had passed, and draw a map.

After the king of Beidi was placed under house arrest in Chang'an, this burden fell entirely on Xiao Jiao's head, and every time he laid down a piece of land, he would add that place to the map.

Over the years, the scope of the northern land on this map has expanded several times, making Jin Yan regret that the land west of the river is still in the hands of the Xiongnu and Yueshi.

"Mother, come closer."

"Mother, I just had a dream, I dreamed of this, here, and here...... There are coal mines in many places......"

"The black thing you mentioned earlier that burns?" Princess Jinyang asked.

Jin Yan "Huh" for a moment, "Did I say that?" ”

Princess Jinyang smiled in her eyes and said dotingly: "You have been different since you were a child, and you often say things that we don't understand, but your mother and your father both remember it." ”

Jin Yan: "......"

So when she was sick and sleepy, how much did she unconsciously reveal out?

You won't spoil all the history that doesn't exist here, right?

Jin Yan was a little weak-hearted.

Princess Jinyang touched her forehead with a smile, "Yan'er don't worry, only our family knows what you were born to know." ”

Jin Yan: "......"

Boy.

Does she not have a little privacy?

Since Princess Jinyang said so, Jin Yan no longer hid, she pointed and scratched on the map with her finger, and pointed out the places containing coal mines, iron ore, gold mines, and limestone.

The others are not in a hurry to mine, and only need to temporarily send people to hold the mine.

The top priority is to mine a large number of coal mines, so that the people of the north can survive this cold winter.
