It is precisely because Lu Heng is completely unaware of the existence of Hantong.

So when the people from the patent office came to tell him.

Not only did he receive a royalty from a vegetable farmer this month.

The vegetable farmer was also using his patent to build a house for himself.

Lu Heng couldn't help but be a little surprised.

After sitting in the office of the academy and thinking for a while.

Lu Heng simply called Wu Zhao and a few other students.

Let an official from the patent office lead the way.

I'm going to go to Hantong's house to have a look.

Take a look at this person who used Lu Heng's patent for the first time in Datang.

What kind of career did you do?

When he came to the brick kiln of Han Tong's house in a horse-drawn carriage.

Looking not far away, Han Tong and his eldest son had just built half of the house themselves.

Lu Heng couldn't help but be a little interested.

After sending someone to find Han Tong and his son.

Lu Heng asked him, "You built this brick kiln just to build a house for your son?" ”

Although there is a fire burning in the brick kiln now, there is no rest of the workers next to it.

Therefore, Lu Heng is basically sure that the vegetable farmer in front of him has not awakened to the idea of burning bricks to sell to others.

"If you go back to the land and the horses, yes, yes." Because the person who came to find him had already informed him of Lu Heng's identity.

So when Han Tong replied, the nervousness was already about to start stammering.

Lu Heng smiled and pulled the old farmer who was too nervous to his side.

He took him around the brick kiln, and then pulled him to sit down with him.

Only then did he slow down and say to him:

"You don't have to be nervous, my Lu Heng is similar to you, I also grew up in the countryside, but I took the emperor's daughter, so I have the identity of a colt."

"Let's talk, you'll be chatting at the time."

After Lu Heng's relief, Han Tong was obviously not so nervous.

Lu Heng saw that he was relaxed, so he asked again:

"I took a look at your brick kiln, and it was built quite well, how many bricks can be produced in a kiln now?"

Han Tong pointed to the house on the side that had almost built a wall and replied:

"Back to the horse, a kiln is all that, I can't count the specifics, but I estimate that if I can burn eight or nine kilns, this house can almost be built."

Lu Heng looked at the bricks over there, and estimated it in his heart again.

Han Tong father and son built this brick kiln, perhaps for their own use.

So the scale is very small, according to Lu Heng's estimate.

A kiln of bricks is burned, that is, three to four thousand.

Remove some that are not up to standard, estimated at a little more than 3,000 yuan.

Look at the foundation he and his son had leveled.

It is estimated that there are eight or nine kilns, and it is really possible to build a small bungalow.

"Then after this house is built, what are you going to do with this brick kiln? Didn't you think about continuing to burn bricks in the future and sell them to other people who wanted to build houses? ”

Facing Lu Heng's inquiry, Han Tong was stunned for a moment, and then said:

"If someone else wants it, it's not that you can't burn some for them."

"Now there are indeed people from the neighborhood who have come to ask."

"It's just that I still plan to build my family's house first."

Through this series of conversations, Lu Heng realized that in addition to this, the vegetable farmer in front of him was indeed a sincere person.

So he simply asked him step by step, "You were originally leading a family and manipulating the family's vegetable garden, right?" ”

"That's right, it's thanks to Master Ma who opened the academy."

"Now the second boy of my family is not only studying in the academy."

"Even the vegetables from my family's vegetable garden were all sent to the back kitchen of the college."

"It saves me a lot of effort to go to the city to sell vegetables every day."

"Today, the second boy of my family is still in the academy."

"Otherwise, I really let him come out and kowtow to you."

Lu Heng smiled and waved his hand, "You don't need to kowtow to me." ”

"But how much money can you make from sending vegetables from your vegetable garden to the college?"

"Now that your brick kiln has been built, if you keep burning it all year round."

"That's a daily entry, haven't you thought about it carefully?"

Lu Heng's words can be said to have stunned Han Tong.

His family's vegetable garden now delivers vegetables to the college every month, and he can earn almost three cents of silver.

Although this is already a lot of income for their family.

It was enough for him to think about building a house for his eldest son and marrying a daughter-in-law.

But what Lu Heng said was right.

Although the vegetable garden can really make money, it still has to be divided into seasons after all.

Not only is there no income in the autumn and winter every year, but the work of manipulating the vegetable garden does not have to burn the brick kiln much easier.

And now this brick kiln has been built.

If only you could really burn bricks in it and sell them endlessly.

Isn't that much better than growing vegetables?

Seeing that Han Tong was moved, Lu Heng continued:

"You see, although this brick-fired kiln requires technology, the work is not easy."

"But you have a lot of clay for burning bricks."

"I see that this firewood was also picked up by yourself in the woods."

"And when you burn the bricks, even if you only earn a penny for a brick, it will be thousands of pennies for a kiln."

"In my opinion, it's better than you grow vegetables, right?"

This account is really not unknown, and I was shocked when I counted it.

In Hantong's view, don't say that this burned brick can earn a penny.

Even if it's ten dollars to earn a penny.

The bricks fired in his kiln can be worth a month's output of his vegetable garden.

Not to mention, if you burn a kiln brick, if you ensure that the kiln is not empty.

It only took six or seven days before and after.

It's going to make this business a living.

Then their family's life is much more relaxed than just running a vegetable garden.

At this time, the insights that Han Tongli had gained from selling vegetables in Chang'an City all year round also quickly took effect.

reacted immediately, and hurriedly clasped his hands into fists, thanking Lu Heng while making a gesture,

"Thank you for your advice, thank you for your guidance, the master of the horse is very kind, and the villain will not forget it."

Lu Heng stretched out his hand to hold him, and said with a smile:

"You don't need to thank me for this, I'll just tell you."

"In the final analysis, this brick kiln is still a hard-working job."

"If you can do it well on your own, it's all your own ability, and it has nothing to do with me."

After Lu Heng finished speaking, he looked at the small building that Han Tong and his son were building.

He said to him, "If you really want to build a new house for your son, then don't build a bungalow." ”

"Although this brick house is firmly built, it is very hot to live in in the summer."

"When the time comes, I'll find a student to come and teach you how to build it, and I'll have to build a small building anyway."

After Lu Heng finished speaking, he also took his group of students back to the college in a carriage.

Leaving only Han Tong, who was full of excitement, stood beside his brick kiln with his eldest son, looking forward to a better life in the future.
