When I returned home, Hantong finally waited until the sun was about to set.

Han Gensheng, the second boy who was studying in the college, returned to the small courtyard of his home with his small schoolbag.

Han Tong saw that his second boy had just stepped into the courtyard gate.

Without saying a word, he slipped him into the house.

made the second son Han Gensheng shout and ask, "Dad, what are you doing?" Let go, don't break my bag. ”

After letting go of his second son, Han Gensheng, Han Tong pointed to the two patents that he had carefully placed on the table and said:

"Quick, show your dad what is written on this."

Han Gensheng first carefully checked his beloved little schoolbag.

After making sure that he was not dragged by his father.

Then he looked down at the two pieces of paper on the table.

While watching, he asked, "Dad?" What is this? Where are you from? ”

"Let you see, you just watch, why do you ask so much?"

Where did Han Tong come from to explain at this time.

He waited at home for a day today, and his heart was burning for a long time.

At this time, I saw that my son was still grinding.

If it weren't for the fear of beating up his own son, he would be stupid.

I've wanted to give him a brain jumper for a long time.

Han Gensheng lowered his head and looked at it for a while, thanking him for his good grades in the academy.

In addition, there are few rare words on these two pieces of paper.

Basically, I still understand it.

"Dad, this seems to be the firing method of the two materials."

"One is called brick, and the other is called cement."

Hearing his son say this, Han Tong immediately became happy.

"Yes, yes, tell your dad about it, how did you get these two things."

"When your dad learns it, he can build your eldest brother a house like the one in your academy."

After listening to this, Han Gensheng picked up one of the pieces of paper, looked at the words on it, and said to his father:

"This one is written on bricks, the materials to be used are loess and water, and the tools are brick kilns."

"The clay is ground first and the impurities in it are sifted out."

"Add 20% of water to dilute the soil and stir well."

"Finally, the clay is made into bricks of uniform size, placed in a cool place, and when the surface of the bricks is dry, they can be fired in the kiln."

"When firing, you need to set the shape with a high fire, and then continue to burn it over a low fire for a day and a night."

"Finally, when the kiln cools, the fired bricks can be taken out of it."

After listening to his son's story, Han Tong can be described as full of confusion.

These processes may not sound complicated, but when combined, there are so many steps.

It's really something that he, who has never been in contact with vegetable farmers at all, can't understand at all.

But Han Gensheng hadn't finished reading it at this time, and still continued:

"By the way, it is also written at the end of this one, the patent fee for this patent is one penny per unit, parentheses, and one penny of patent fees need to be paid for every hundred finished bricks fired."

After reading the information on the paper.

Han Gensheng raised his head and asked, "Dad, what is the patent fee?" Where did you get this? ”

At this time, Han Tong, who felt that he probably couldn't get this brick, was also a little frustrated.

Sitting on the bench next to him, he said:

"Isn't it written on the patent fee? It's to burn a brick and pay a penny. ”

After Han Tong finished speaking, he told his son the origin of these two pieces of paper again.

In the academy classroom where I heard that I go to school every day now.

It was built with bricks and cement on these two sheets of paper.

Han Gensheng was very excited to read the two pieces of paper several times.

Only then did he ask his dejected father:

"Then Dad, you went to the patent office to get something and came back, are you planning to build a building like the academy for your family?"

Han Tong glared at his son angrily,

"Do you think your father was the one who could build a building like that?"

"I brought them back to see if I could build a similar house for your brother, so that your brother could find a daughter-in-law quickly."

After Han Tong finished speaking, he couldn't help but sigh again,

"But now it seems that this brick is too troublesome to make, and your father is afraid that he won't be able to make it."

Hearing his father's words, Han Gensheng's little brain turned.

Immediately gave his father an idea.

"Dad, if you can't learn it yourself, you can go to the brick kiln in the academy to learn?"

"Every day, there are a lot of wagons pulling bricks to our academy to build new classrooms."

"Where are you going to learn from someone for a few days, maybe you'll be able to learn it?"

Don't talk about your own son's idea.

That suddenly made Han Tong clever, which seems to sound like an idea.

After thinking about it for a while.

Hancom has also made up its mind.

I'll go to that brick kiln tomorrow and see if I can learn this thing by myself.

In the evening, I waited for my wife and son to come back from the vegetable garden.

Han Tong also told them about his plans.

Although both of them felt that Han Tong was working in vain.

But now the vegetable garden is also busy.

It was for the sake of his eldest son marrying a daughter-in-law.

So neither of them objected.

The next day, after my youngest son went to school.

Han Tong also waited for a fixed carriage from the academy to Chang'an City.

I paid another two cents for the ride and rode in a carriage to my son's college.

These carriages were originally opened by Lu Heng in order to facilitate the students to go to and from school.

But then, as more and more people wanted to hitchhike.

Lu Heng simply let them pick up and drop off the students.

Two more runs a day in the morning and afternoon.

It can be regarded as the first fixed bus route in the Tang Dynasty.

Riding a carriage to the academy, Han Tong waited until the carriage that sent the bricks arrived.

went up and pulled a homely climb relationship.

Finally, after learning that the brick kiln is indeed recruiting temporary workers.

Hurriedly took the return brick-pulling carriage to the brick kiln.

In the following ten days, Han Tong also became a temporary worker in the brick kiln.

Not only does he get paid for his daily work, but the key is that he has also learned the process and know-how of burning bricks.

In addition, I took advantage of this opportunity to run a few times to the cement kiln next to it.

It's like I've learned both crafts.

In fact, Han Tong didn't think about it, so he bought some bricks and cement on the brick kiln and went back to build a house for his eldest son.

But because of Lu Heng's two brick kilns now, it is not enough to supply bricks and cement for school construction.

So it's impossible to take it out.

Hantong can only continue to learn honestly.

Finally, after working in the brick kiln for more than half a month.

Han Tong finally felt that he had learned almost everything.

Then he went to the office to settle his salary.

Returned home with two crafts.

For a period of time after that, Han Tong took his eldest son to do farm work in the vegetable garden almost always in the morning.

In the afternoon, the family went to build their own brick kiln.

Just like that, more than a month has passed.

Hantong finally burned the first kiln bricks in his own home!
