A bright smile appeared on Qin Fan's face, and he immediately turned around and shouted in the direction where Xiao Er left, "Please go and bring over the most expensive thing you have here, I will be of great use."

That Xiao Er looked puzzled, not knowing what Qin Fan's intentions were.

"Hurry up!"

Qin Fan glared at her and shouted.

"Yes, yes, I'll go get it right away, Qin Gongzi wait for a while."

The little second was taken aback, and quickly turned around and left the place.

After a few breaths, the little two ran back with a huge red wooden box, placed the wooden box on the ground, and began to fiddle with the contents of the wooden box.

Qin Fan walked to the side of the wooden box, looked down at the things in the wooden box, and his face suddenly became wonderful.

In that wooden box, there were three strange plants of dark green.

The plant looks plain, just an ordinary weed, but it contains a hint of creepy atmosphere.

And the soil around it is a very hard golden stone.

This kind of gold stone is more difficult to find than those ores.

Not only that, but the branches of the three plants were very thick and covered with dense spikes, and if anyone approached the three plants, they would definitely suffer great damage.

Qin Fan carefully observed the three plants, and his face couldn't help but show joy.

Because, he can be sure that these three plants are definitely rare 10,000-year-old Ganoderma lucidum.

Qin Fan slowly opened the wooden box, and then swallowed his saliva.

"Qin County Order, these three 10,000-year-old Ganoderma lucidum, our boss said that they were given to you."

As soon as Qin Fan put down the wooden box, a voice sounded in his ears.

So Qin Fan raised his head and saw a young man in a black robe standing next to him.

This young man was handsome, with sword eyebrows and starry eyes, and he looked heroic, and a Ling Ran righteousness gushed out of his body.

"Then thank you, but I, Qin Fan, won't take your things for nothing."

Qin Fan said with a chuckle.

After finishing speaking, Qin Fan waved his palm, and a gold card instantly fell into the hands of the middle-aged man.

The middle-aged man took the gold card, the smile on his face became brighter and brighter, and said, "Since this is the case, then we will have a meeting later."

"Well, I'm looking forward to working with you too."

Qin Fan bowed slightly, and said with a smile on his face.

"These 10,000-year-old purple lazuli stones are placed here, you can pick a few random pieces and try them.

When the middle-aged man left, Qin Fan began to select the contents of these wooden boxes.

There were very few things he had a crush on, they were all very common, but they were quite expensive.

After some selection, he selected ten pieces of 10,000-year-old purple lazuli and prepared to go back to do the test first, and then make plans.

Then Qin Fan took ten pieces of 10,000-year-old purple lazuli and left the shop.

"Miss, that guy surnamed Qin has left the store, what should I do now?"

A man dressed in a fancy costume and about two meters tall bowed to a woman and asked, this person was the eldest grandson Yudie that Qin Fan had met before.

"Keep an eye on him, and if there's any movement, be sure to report me in time."

The eldest grandson Yudie said lightly.

The servant said respectfully, "Okay, Miss, my subordinates will always send someone to keep an eye on Qin Fan."

The eldest grandson Yudie nodded slightly, then turned around and walked outside.

The servant and two bodyguards followed, a group of four, speeding off into the distance.

......

In the evening of the same day, Qin Fan returned to the county office, and on this day, he gained a lot, but also made the young people feel a little tired

Guo Qin Fan was indeed not ready to rest, because his bet with the eldest grandson Wuji was about to expire, and it was time to think about how to increase the potato production in Wannian County.

"These potatoes are still not enough."

Qin Fan frowned

frowned, muttering to himself.

He had already asked Zhao Lao to help find out the news, and if there were any surplus potatoes in the surrounding counties, he would send them over immediately.

"There aren't many potatoes, but they're better than nothing."

After thinking about it for a while, Qin Fan decided to start buying grain when this time passed.

There were also a hundred acres of land in his storage ring, which was now also deserted, and these lands were all grain he had planted in his spare time, and which was watered every once in a while.

It's just that how to continue to increase production, Qin Fan is not very clear.

"Forget it, I'm not short of money right now anyway, so I'll figure it out slowly."

Qin Fan sighed, and then continued to sort out the treasures he had bought.

In the palm of his hand, there were ten amethyst stones.

This amethyst is used to make car shells

Cars are not complicated, Qin Fan believes that with his own level, he will definitely be able to make them.

But now Qin Fan has only barely collected the materials to make the car shell, and other things still need to be planned slowly.

Qin Fan thought about it for a long time, and finally decided to start with automotive materials first.

"First of all, you have to find materials that can make other parts of the car......," Qin Fan muttered.

"It's a pity that there is no electricity in this world, and there is no Internet, if there is an IFI......

"But ......"

Qin Fan suddenly remembered something, and his eyes lit up.

Although Qin Fan had never touched such a thing as a car when he was on Earth, he knew a lot about the manufacture of car shells.

Most of the car's shell is made of alloy, which not only has strong defense, but also can increase speed.

In ancient times, the shell of a car was a weapon of war!

"The ......"

Qin Fan suddenly had an idea: "I haven't eaten pork, I've always seen pigs run, just try it."

When Qin Fan made up his mind, he straightened out his thoughts clearly, and then began to think about how to make the quality of the material the best.

Under normal circumstances, the materials needed to make a car are basically disposable consumables or high-tech products, so Qin Fan's goal is to find the most convenient method.

For example, adding appropriate metal to the car shell and placing materials such as steel bars in the shell make the car shell extremely strong.

But Qin Fan still lacks steel materials.

Qin Fan looked out the window, it was already night at this moment, and he knew that he had been delayed for too long.

If the car is really successfully manufactured, then the spears and broadswords in the hands of those Tang soldiers will instantly become decorations.

And the arrival of the purple lazuli right now has undoubtedly given Qin Fan a shot in the arm.

This incomparably hard stone is undoubtedly the best material for making car shells.

"It seems that the annexation of the Liu family must be done as soon as possible, only in this way can I obtain a steady stream of resources."

"And that gold mine can start mining too."

Qin Fan touched his chin, and a thoughtful look appeared on his face.
