[Amethyst]: Purple treasure chest, which can upgrade grain production.

Qin Fan was overjoyed in his heart, so that the bet between him and the eldest grandson Wuji had an eyebrow.

Originally, the eldest grandson Wuji didn't believe that Qin Fan could grow potatoes of 5,000 stones in three months.

But now that the latter has this skill, it's not something that can be easily captured.

Originally, Qin Fan was still worried about this matter, but now the arrival of the purple treasure chest undoubtedly doomed the eldest grandson Wuji to failure.

Qin Fan clenched his fists, and a look of determination flashed in his eyes.

......

Early the next morning, Qin Fan came to a field outside the city, where a lot of rice had been planted at the moment, and it looked very neat.

The harvest during this period of time has been very rich, adding up to a range of five or six thousand mu, these are all pesticides that Qin Fan configured with elixir, which can make crops mature quickly.

Qin Fan set his gaze on the center of the field, where a wooden stake was piled up.

This is the anvil that Qin Fan wants to refine, this thing was specially ordered by someone when he was in the town yesterday, because he planned to build a warehouse in the town that was specially used for refining weapons.

This is very important for Qin Fan's next plan, whether it is to build weapons or make cars, it must start here.

Qin Fan's purpose today is actually very simple, he had already sent someone to send five hundred catties of pig iron, and he wanted to refine a special material for refining weapons here.

Qin Fan poured all these materials into the anvil, then roasted the iron pieces dry with a flame, and then began to calcine.

The iron kept turning red and hardening, and finally, after an anvil was burned red, Qin Fan smashed it with a hammer.

"Bang ......"

There was a dull thud, and an iron plate was smashed out of a huge hole, revealing the white steel bars inside.

"It's such a hard piece of iron." Qin Fan couldn't help but admire.

"My lord, can the current flames melt the iron?" The blacksmith on the side asked cautiously.

"Absolutely." Qin Fan nodded, staring at the stove in front of him without turning his mind.

The iron was incinerated and soon smelted into a lump of liquid.

"It took me two days to smelt these liquids, so let me see what they do." Qin Fan thought in his heart.

"Hum......

In the next second, the liquid changed wonderfully.

I saw that they slowly dissolved and merged into the anvil, and then a layer of yellowish oily substance appeared on the surface of the anvil.

But in the next second, the iron plate instantly became extremely strong, and Qin Fan frequently felt that his experiment today was about to succeed.

"This strength is enough to compare with ordinary alloys." Qin Fan said in amazement.

He then continued his attempt, instructing the blacksmith beside him to keep the flame in temperature.

The surface of the iron suddenly made a "Zrazra" sound, and black smoke began to emit, but it did not affect the liquid in it at all.

"Yes, yes, it's a high-grade material." Qin Fan said with satisfaction, "It seems that I am going to make a lot of money this time."

Qin Fan thought excitedly in his heart, but he didn't let his guard down because of all this.

Next to this anvil, Qin Fan picked up the other materials and threw them all into it, and after some busyness, these materials all melted and were then quenched into a liquid mass.

Qin Fan said silently in his heart, "Refining is successful."

"Ding." Congratulations to the host for completing the task: preliminary purification.

Rewards: Five high-grade ores, Dark Iron

This ore is a scarce mineral that can be used to forge blades, but the price in the market is quite expensive, or even priceless.

Qin Fan was overjoyed in his heart, and hurriedly put the material of this high-grade ore into the anvil to smelt, and then used it to refine weapons.

Although this ore is not as strong as iron, it can withstand more power and is far tougher than iron, making it the best choice for refining blades.

Qin Fan nodded with satisfaction.

"This kind of high-grade refining material is definitely a sought-after item even if it is placed on the market.

"Now, my strength should have improved again."

Thinking of this, he was secretly happy in his heart.

"Lord Prefectural, what are we going to do next?" The blacksmith wiped the sweat from his forehead.

"I'm going to go to town to buy another batch of materials." Qin Fan opened his mouth and said.

"You're here guarding the stove and making a sword for me out of this new material."

"Yes." The blacksmith nodded without hesitation, it was not a difficult task for him.

Qin Fan nodded with great satisfaction, and then he stepped onto a group of tall war horses and walked towards the town to which Wannian County belonged.

The day agreed with the eldest grandson Wuji is getting closer and closer, Qin Fan wants to go down to harvest some seeds in person today, and feel good that he will sow them before the arrival of this prime minister.

Qin Fan was full of confidence in this bet, he could imagine the shocked expression of the eldest grandson Wuji when he saw those potatoes, and he couldn't help but feel very happy.

But a kilometer away from the blacksmith shop, Qin Fan found a group of people standing there.

The leader was a middle-aged man, about forty years old, with a long beard, tall and mighty, dressed in black, looking domineering and awe-inspiring, and he was the deputy town guard of Qinwang Town.

"Lord Zhao, do you think we can catch the beast this time?" A young man in a brocade robe looked at the deputy town guard and said, his tone was a little apprehensive.

"Do you still need to ask this?" The deputy town guard snorted, "This time, our mission is to capture this evil tiger and kill it here as an example."

"Lord Zhao is wise, I knew that you would be able to complete this mission." The brocade-robed young man patted his ass and said.

The deputy town guard waved his hand and said, "I'm not as good as you say this time, and this mission is a bit difficult."

"Lord Zhao, don't be modest, you are the number one master in Qinwang Town.

Hearing this, the deputy townkeeper's eyes narrowed, and then he smiled and said, "In that case, then I'll do my best."

"If there is anything needed, Lord Zhao may command." The brocade-robed young man immediately arched his hand and said.

"You stay here first, and I'll contact you when I'm in town."

"Okay."

......

Deputy Zhao Zhen's guard waved his hand, and suddenly a group of people and horses walked out from behind him, holding spears, bows and arrows and other weapons in their hands, looking imposing, and at a glance they knew that they were specially trained soldiers.

"Brothers, come with me." The deputy town guard let out a loud shout and led the group towards the town.

There were hundreds of people in this team, all of them were fully armoured, and the mounts under their crotches were all black horses, each of which was more than two meters long and pitch black.
