Speaking of abacus, Li Yuanjia is quite familiar.

He still remembers the mantras of "one to nine into one" and "nine to one into one", and also remembers that the abacus is two parts, two beads on the top and five beads on the bottom......

Compared to cement, the abacus is simply too simple.

The only thing Li Yuanjia needs to worry about is the quality of the beads, after all, with the craftsmanship of the carpenters in these years, it is definitely not easy to make thin wooden poles one by one, let alone wear so many small round beads on them, and those beads must also be able to move up and down smoothly to withstand the hand speed of the abacus masters......

The future is very simple, and it will not be too easy to put it in Zhenguan for twelve years.

But it's still the same sentence, no matter how difficult it is to make an abacus in the twelfth year of Zhenguan, there is no need for Li Yuanjia to worry about it himself anyway. Struck while the iron was hot, and after returning to the study, he directly drew the appearance of the abacus, and after marking the size clearly, he directly called Han Lucheng over: "Give this thing to Chen Mu and ask him to find someone to make one for me...... You can see this, right? ”

"Back to the king, the little one understands."

After carefully looking at the drawings in his hand again, Han Lucheng nodded very affirmatively.

It's just a wooden frame, with a few wooden sticks in it, and some round beads on it, what's not to understand? At a glance, is it clear?

"Well, that's good."

Nodding, Li Yuanjia said with a smile: "Then tell Chen Mu for me that the beads on it must be light and smooth, and they must be flicked with a finger to move up and down!" ”

"Yes, my lord."

After thinking for a while, Han Lucheng nodded again, indicating that he understood.

"Go ahead...... Well, that's right! ”

Waving his hand, just as he wanted Han Lucheng to leave, Li Yuanjia suddenly remembered something and stopped him again: "I remember that Han Shan went to the dumping workshop outside the city, and he has been staying for a long time, right?" ”

"Yes, my lord, it's been more than a month."

Hearing him ask about his father, Han Lucheng's heart suddenly burst out, and he quickly nodded respectfully.

"Hmm......"

After confirming this matter, Li Yuanjia's eyes narrowed slightly, sat on the wide Taishi chair, and began to gently tap the table in front of him with his right index finger.

Lao Han's thoughts, in fact, Li Yuanjia can also guess a little.

It is nothing more than that he served Li Yuanjia on the orders of the imperial concubine more than ten years ago, and has been a housekeeper in the palace for many years, Han Shan must have a high opinion of himself in his heart. This point, in fact, Li Yuanjia was faintly aware of it a long time ago, especially when he was still young, he was cautious, Han Shan really decided a lot of things for him.

But since Li Yuanjia was named King Xu and went to Luzhou, everything has been different.

The king, who has been obedient since childhood, suddenly had his own thoughts, and suddenly began to let people do a lot of strange things, and suddenly he was doing business and opening a store...... Of course, more importantly, an obedient king suddenly became extremely tough, and no matter what he did, he would not give Han Shan any chance to object!

After many times, Han Shan also sensed that something was wrong.

Later, Li Yuanjia implemented Tianzhu numbers in the palace, implemented a new style of bookkeeping, and built various workshops outside Chang'an City, which also made Han Shan feel a strong sense of loss - he finally found that he could no longer keep up with the king's ideas, and even began to make the king feel disgusted.

So when his son Han Lucheng was more and more valued by the king, Han Shan suddenly proposed to go to the dumping workshop outside the city to help, and he has not come back until now......

Looking at Han Lucheng, who had a worried face, Li Yuanjia was a little entangled.

To be honest, he now feels that Han Lucheng is very easy to use, and he no longer wants to be followed by Han Shan. It's not that Li Yuanjia hates his old housekeeper, it's really that old mind is too old-fashioned, and many things Li Yuanjia wants to do have to be organized...... Although it doesn't change anything every time, it's really annoying after a long time.

So when Han Shan said that he wanted to go outside the city, Li Yuanjia happily agreed.

But now that he suddenly found that he had been gone for more than a month, and he didn't seem to have any intention of coming back, Li Yuanjia couldn't help but ask. And now looking at Han Lucheng's expression, Li Yuanjia felt a little guilty, was he too harsh on the old man who had served him for more than ten years?

Li Yuanjia thought about it here, and Han Lucheng next to him became more and more worried in his heart, and asked in a low voice after a while: "King, King?" ”

"Huh? Oh. ”

Li Yuanjia, who came back to his senses, glanced at Han Lucheng, nodded and said, "Okay, go back and let your father come back, I have something to find him...... Well, let's wait until things settle down at the tipping workshop. ”

"Yes, King!"

A flash of joy flashed in his eyes, and Han Lucheng hurriedly bowed and saluted, with a happy smile on his face......

……

"Your Majesty, it's time to eat."

After sitting in the study for I don't know how long, Li Yuanjia suddenly heard a gentle and lovely voice, which woke him up from his work state. hurriedly looked up, and sure enough, it was his princess Fang Fengzhu who arrived.

Li Yuanjia, who was writing, hurriedly put down the pen in his hand, and stood up with a slight frown: "Fengzhu, it's just a trivial matter for Siqi and them to come here, why do you want to come here in person?" But today is really strange, obviously the morning is quite warm, why is the afternoon suddenly so cold...... Well? ”

"King, what's wrong?"

After seeing Li Yuanjia's sudden change in expression, Fang Fengzhu was shocked and hurriedly asked.

"Oh, it's okay, it's okay, hehe."

After laughing dryly, Li Yuanjia hurriedly waved his hand, indicating that there was nothing important. It's just that he smiled at his wife on his face, but Li Yuanjia secretly screamed bitterly in his heart!

Just now, he suddenly remembered those "concrete" in the small courtyard!

In such a cold weather, even if there are two stoves in the study, and special treatment was made to the walls and roofs when it was renovated, and even a blanket was laid on the ground, Li Yuanjia can still feel the strong chill, and his hands are so stiff that he can't hold the pen when he writes, what should I do with the concrete in this case?

But now is not the time to worry about cement, Li Yuanjia stepped forward and grabbed Fang Fengzhu's little hand, and said with a smile: "It just so happens that I'm hungry too, let's go back to dinner...... Phew, it's really strange today, and it feels cold. “

"King, that's because it's snowing!"

"Huh? Snowing? “

After listening to Fang Fengzhu's words, Li Yuanjia hurriedly walked to the door of the study, pushed open the door and walked out to take a look, sure enough, the sky was gray, and the snowflakes were fluttering and falling down one by one.

In the winter of the twelfth year of Zhenguan, the first snow in Chang'an City came a little later than in previous years.

However, seeing the snowflakes flying in the sky, Li Yuanjia was first happy, and then his face changed again, and a touch of melancholy flashed in his eyes......
