Liu Hao excitedly called up the system light curtain, the light curtain was touched, and suddenly it flashed and became the form of a turntable, with a conspicuous cursor pointer on the turntable, and another batch of subtitles also appeared.

Note 1: All items and technologies that have appeared on Earth can be drawn.

Note 2: The larger the gap between the items and the plane system, the smaller the probability of being drawn, such as mobile phones, TVs, thermal weapons and other high-tech products.

Looking at these two annotations, Liu Hao quickly understood the meaning of the system.

At this time, the level of social development in this world is too backward, and it is impossible to use mobile phones, TVs and other technological products.

For example, whether they draw a plane or a mobile phone now, they can only use it as an ornament, and it is of no use at all.

On the contrary, if he draws some more affordable items, such as a large amount of food, such as some basic technologies that are not yet available in this world, it will be of great use.

After understanding the meaning of the system, Liu Hao shrugged his shoulders and clicked to start the lottery.

There are three areas on the lottery interface, but the text on it is all random, and I don't know what it is.

Bar, the lottery began, the cursor hand on the small roulette wheel flicked, and it instantly rotated at high speed in a clockwise direction, and it took about five or six seconds to turn dozens of times before the speed slowed down, slower and slower, slower and slower......

Eventually, the pointer crossed and stopped at the third area.

"Ding~ Congratulations to the host for winning a random prize box, please check. ”

Liu Hao clicked on the package and saw a book lying quietly in the package:

Mining!

Seeing this reward, Liu Hao directly squirted a mouthful of old blood.

This is too chicken, do you want him to be the emperor to open coal mining?

Hey, coal ......

Liu Hao's eyes lit up, and the whole person suddenly brightened.

Since the system has given him the mining technique, does it mean that there is coal in this world?

Liu Hao learned the mining technique.

Immediately, the mining technique turned into a beam of light and burrowed into his mind.

Then, lines of text appeared in his mind.

Liu Hao took a general look, this mining technique is not only the mining technology of various ores, but also the measurable technology, in this era, it is completely super magical.

"Someone. After Liu Hao finished watching the mining, he couldn't wait to go out of the city to see if there were coal mines in this world.

If there is a coal mine, it will not only allow the people to survive this winter, but also make a lot of money, and start the development of business.

"Your Majesty. The eunuch hurried in.

"Spread Cao Meng and Nie Bu to see me. Liu Hao commanded.

"Yes. The eunuch answered and withdrew.

About twenty minutes later, Cao Meng and Nie Bu came to the Chengde Hall one after another.

"The minister Cao Meng (Nie Bu) has seen Your Majesty. The two came in and saluted.

"The two Aiqing are flat, and I summoned you here to let you accompany me out of the palace. Liu Hao said directly.

"Your Majesty, a large number of displaced people have recently poured into the imperial capital, and the entire emperor is very unsafe, and it is too dangerous to leave the palace. Cao Meng hurriedly persuaded.

"With Nie Aiqing here, don't be afraid, besides, I am out of the palace in micro-service, and there are not many people who know about it, and even fewer people can recognize me. Liu Hao shook his head and said.

In the past few nights, he has not slept and has been practicing the magic skills of the First Emperor of the Ages, and he has broken through to the second level, and his strength has reached 30, and ordinary people can't help him.

The most important thing is that he still has Nie Bu, the number one military general in Great Xia, by his side, and there is no one who can hurt him.

And Cao Meng's own force is also good.

Seeing His Majesty's insistence, Cao Meng thought of the scene where His Majesty slapped Nie Bu a few days ago, so he nodded in agreement.

However, he still called a few of the best of Yu Lin Lang to secretly guard, just in case.

After the three of them changed into ordinary clothes, they got into the carriage and quietly walked out of the palace, while Nie Bu turned into a coachman, and behind them was a group of Yu Linlang who also changed their clothes to secretly guard.

"What is the matter with Your Majesty leaving the palace?" After leaving the city, Cao Meng, who was sitting outside the carriage with Nie Bu, lifted the curtain and asked in a low voice.

"I look at the land of Great Xia, there must be treasures buried, and I am ready to go out and have a look today. Liu Hao raised his eyebrows and said.

Anyway, people in this era don't know what coal is, so he can only make it up.

Nebu's eyes lit up, not knowing what he was thinking.

But Cao Meng frowned, feeling that the emperor was a little unreliable.

However, he didn't ask too much, after all, they had already come out, so he should be crazy with the emperor.

As for what kind of treasure it was, of course he didn't believe it.

If there were any treasures, I am afraid they would have been excavated by their predecessors a long time ago.

Along the way, Liu Hao constantly used the Kan Technique to survey the land under his feet.

Finally, in Xishan, five or six miles away from the imperial capital, Liu Hao received a system prompt.

"Ding~ found that the storage capacity of high-quality coal mines is 20 million tons, only two meters above the ground. ”

There really is a coal mine!

Hearing the system prompt, Liu Hao almost didn't cry out excitedly.

Sure enough, there would be no waste system in this world.

The system allowed him to draw the mining technique in the first lottery, so it must have its intentions.

The two things that have given him some headaches recently are that the people spend the winter and find opportunities to develop business, and the discovery and promotion of coal mines can solve these two problems.

"Stop!" Liu Hao shouted to Nie Bu outside.

"Huh~~" Nie Bu pulled the stiff rope and stopped the carriage.

"Your Majesty. Cao Meng lifted the curtain.

"Get out of the car. Liu Hao said and jumped out of the car.

"Your Majesty be careful. Cao Meng was just about to reach out to help Liu Hao, but found that Liu Hao was already standing firmly on the ground.

Liu Hao walked to a place with gentle terrain and said to Cao Meng: "Right here, ask them to come and dig a pit for me." ”

When he came out, Liu Hao asked the dozens of Yulin Lang to bring tools, so that if they encountered shallow coal, they could dig it out directly to see if it was true.

Although he believes in the system, he trusts his own eyes even more.

Soon dozens of Yu Linlang ran over, and Cao Meng asked, "Your Majesty, what are you digging a pit for?

Liu Hao smiled and nodded, with a little excitement on his face.

"Your Majesty, is there really a treasure underground?" Nie Bu also asked curiously.

Even the Yu Linlang who was digging the pit stopped and looked at Liu Hao, their eyes full of disbelief.

"Yes, there are a lot of treasures buried under this land, as long as they are dug up, the people of my Great Xia will have a good life in the future. Liu Hao said confidently.

This is a chain reaction, as long as he opens the curtain of vigorously developing commerce, the national strength of Great Xia will become stronger and stronger in the future, and the people of Great Xia will become richer and richer.

"Really, is it fake?" Cao Meng was also a little shaken, and when he saw Liu Hao say it so seriously, he also believed it a little.

"It's definitely true, you can dig two meters down, so let's dig it quickly. Liu Hao said.

When the Yulin Lang heard this, whether they believed it or not, they all dug down hard.

Anyway, it's only two meters, and it won't take much time to dig.

After a stick of incense.

Eventually, the earth beneath the ground began to turn black.

Liu Hao was a little excited in his heart, it is true that there is indeed coal underground.

"Speed up the digging, it's fast. Liu Hao urged again.

Seeing that His Majesty was so excited, both Yu Linlang and Cao Meng Niebu believed it a little.

After another stick of incense......

"Your Majesty, is this the treasure you are talking about?" Cao Meng asked Liu Hao curiously with a piece of coal weighing more than ten catties.

The Yulin Lang also stopped, not knowing what this black stone was.
