Zhao Jun was still in shock.

It wasn't until Juzi called her repeatedly that she came to her senses.

"Sir, I'm just confused. You don't have to take it too seriously."

Seeing her stunned, Juzi thought she didn't know.

"No, I'm just surprised you asked that question."

Speaking of this Zhao Jun, I actually know a little bit about him.

"Iron can be made into far more things than bronze, and it's not as precious as bronze."

"The reason why it can't be widely used now is that the iron smelting technology is not yet mature."

"Like you said, it's quite brittle and not very tough."

"I do know some methods, but I don't know whether they can be implemented."

"To increase the strength, you need to heat the iron-containing stones to high temperatures to turn them into molten iron, then hammer them after they cool down to make real ironware."

This is what Zhao Jun happened to see in a book not long ago.

"So that's how it is. I understand. I'll experiment with it when I have time."

Juzi smiled foolishly and scratched his head.

After answering the question, Zhao Jun walked slowly towards his palace.

Along the way, she was thinking that Ju Zi's ironware actually gave her inspiration.

About what you will do next.

Now she has basically completed the step of increasing grain production in agriculture.

After all, only by ensuring sufficient food can we talk about what happens next.

Then there's business.

After people have enough to eat, of course the next step is to have jobs and make money.

Now she is doing this first thing.

From papermaking workshops, trade markets, fish ponds to today's cotton processing plants.

She has built up her job step by step.

But of course it's still not enough.

The population is large, but the jobs it creates are still too few.

Her next focus will still be on opening workshops.

But why did she say that Ju Zi’s words just now inspired her?

Because iron tools will definitely be widely used in the future, she will definitely pay attention to this aspect in the future.

Now that a big shot has experimented with it first, the results will naturally be better.

It was because of what Juzi had just said to her that she remembered something she must do.

Whether it is iron smelting or something else, there are certain things that are needed.

That's 'coal'.

It's time for her to take the handmade craze a step further.

Nowadays, people basically use firewood as a burning tool.

But whether it is the high temperature required for iron smelting or the convenience.

Coal is definitely the best choice.

Moreover, coal can also bring greater benefits and more changes.

It just so happens that she has time now, so she can check whether there are any coal mines around Xianyang.

It can also be used as a place to relax and have fun.

Do what you say.

When Zhao Jun returned to the palace that night, he told Qingliu the news.

Of course, it also received unanimous approval from Qingliu.

The next day, Zhao Jun greeted the captain and prepared to take Qingliu and Fusu on a treasure hunt.

Of course, she was not completely unprepared.

She didn't know the exact location of the coal.

But she asked her modern sister Sun for a map of China's coal distribution.

The content is very detailed, including a map of the area around Xianyang, Shaanxi.

Although many landforms have changed over thousands of years, the directions are still roughly outlined on the map.

So as soon as she left the city gate, she led her men south.

Zhao Jun didn't plan to go far and basically just explored the area around Xianyang.

"But, Xiao He, who asked you to come? It's fine if you just came, but why did you bring him as well?"

The King of Zhao sat in the carriage, his eyes moving between Xiao He and Liu Bang who were riding horses behind him.

Qing Liu, who was sitting next to her, smiled awkwardly.

"Haha, sir, I was the one who called Xiao He here. I happened to meet him when I was leaving the palace this morning."

"As for that person, that has nothing to do with me."

Qingliu quickly waved her hand to draw a clear line between herself and him.

"Sir, excuse me for disturbing you. I had planned to go sightseeing in the suburbs with Liu Ji today, but I didn't expect to run into Qing Liu and ended up joining us."

"Don't worry, sir. Liu Ji came with me. I will make sure he doesn't cause any trouble for you."

Xiao He smiled apologetically.

Liu Ji, who was riding beside him, started yelling again.

"Sir, why do you dislike me so much? I won't cause any trouble."

"Not only will I not cause any trouble, I will also help you with your work."

"It was thanks to you, sir, that I finally found the storytelling career I love."

Liu Ji was so excited that the horse under her almost threw her off.

Fusu, who was riding a horse on the other side, silently looked at the person who was speaking.

It turned out that he was Mr. Liu, the storyteller they talked about last time.

"Okay, just don't go back and write about our treasure hunt in your story."

Zhao Jun shouted loudly.

Liu Ji felt a little embarrassed, as if his secret had been exposed.

Xiao He glared at him, implying that he should not cause trouble.

"Okay, okay, I definitely won't write that in."

"But, sir, treasure hunting, what treasure are we looking for this time?"

Not only Liu Ji, but also Xiao He, Fusu and even Qing Liu were very curious.

Because Zhao Jun only told them that he wanted to go treasure hunting, but did not say what he was looking for specifically.

Even Fusu, who was standing beside her, was very curious about what she said.

"This treasure looks like a black stone. It's usually not very noticeable, but it's much darker than ordinary stones."
