As the sun sets, under the hard work of the Huotou Battalion, all the grain has been put into storage, which perfectly explains what it means to have more people and more power.

Lu Zhi stood in front of the desk of the baggage officer Liang Chong, and raised his eyebrows, "How is it?" Lord Liang, it's just a little more, right? ”

Liang Zhong closed the account book in his hand and smiled, "I still believe in the credibility of the Lu family." ”

Lu Zhi pursed his lips secretly, pure nonsense, you didn't say that before entering the warehouse, you were completely unkind.

Of course, it's okay to say it's business.

"Lord Liang, the last time we met, I was too hurried, and I didn't say anything, after I went back, I thought about it, and I felt that I didn't do things well enough."

"Hey, Brother Lu Zhi, what are you talking about?"

Lu Zhi waved his hand and climbed along the pole, "Brother Liang, this matter is wrong with the junior brother, and I haven't even prepared a meeting gift." ”

"It's okay, it's okay." Liang Chong's "loan" of grain has made a profit, and it is the time to be happy, and his favorability towards Lu Zhi is extremely high.

"That's not going to work." Lu Zhi took out a small object from his arms, quickly stuffed it into Liang Chong's arms, and stuffed the phantom.

Obviously, this is already Lu Zhi's peak speed, and it is an attribute bonus.

Liang Zhong had been watching the warehouse for most of the day, his eyes were already bad, and Lu Zhi's hand speed was too fast, he didn't see anything clearly, and thought it was silver.

He didn't dare to accept the money, so he hurriedly excused himself and said, "Brother Lu Zhi, I can't help it!" ”

Unlike ordinary soldiers, or personal guards, the position of a baggage officer is somewhat sensitive, and if you are not careful, you may move your head.

"I can't do it, it's just a wooden gadget." Lu Zhichu smiled narrowly, and deliberately stuffed it faster, just so that Liang Zhong didn't have time to react.

And Liang Chong's reaction should be scared of being beaten hard.

Liang Zhong lowered his head, and the object still showed half of the small corners, which were indeed wooden.

He took it out, and saw that it was boxy, interspersed with sticks, and beads were worn on them.

Lu Zhigong arched his hand, "Brother Liang is in charge of baggage, and he often has to write and calculate, and the younger brother is not talented, so there is only this little bit of craftsmanship, and I hope that Brother Liang will not dislike it." ”

Liang Zhong looked at it for a long time, and held back a question, "Brother Lu Zhi, what is this?" ”

With a flexible mind, Liang Chong's life is good, and he has seen a lot of good things, but he doesn't know this thing in front of him.

"This is an abacus, a count." Lu Zhi hehe, hey Yile, don't talk about Liang Chong, even if it is placed in the entire Dayue, no one else knows this thing.

This is his latest "invention".

√, it's an invention, anyway, no one knows where Lu Zhi copied it from, it's his invention.

"You see, in this rectangular wooden frame, a string of equal numbers of abacus beads is arranged, and there is a beam that divides the beads into upper and lower parts, and the abacus beads run through the straight column, commonly known as "file". ”

"Generally 9 gears, 11 gears or 13 gears, I do this to take the center, 11 gears, the file is horizontal to the beam, 1 bead on the beam, this bead is 5; 5 beads under the beam, each bead is 1. ”

"Counting?" Liang Zhong got back to his heart this time, and began to move his hands up and down, constantly groping.

It is said that interest is the best teacher, and Liang is super good at arithmetic, and the reason is that he likes to count, "How do you use this abacus?" ”

"Look." Lu Zhi took the abacus, "Let's have one plus one." ”

He flicked the beads under the beam, first one, then one, "This is two." ”

"Hmm." Liang nodded emphatically, "Yes, one more." ”

"Okay, look at it again, four plus one is five." Lu Zhi tossed all the beads under the first gear beam, and then plucked them down, "Five under the beam is equal to one on the beam...... What do you think? Simple, right? ”

Liang Zhong hesitated for a moment, "It's okay." ”

I don't know how to pretend to understand, I can't tell it myself, can you still understand? What about fools? …… Lu Zhi laughed dryly, "There is also a formula, just say add one, one on one, five to four, one to nine." ”

Liang Chong's brows tightened, "What else?" ”

"And ...... Brother Liang, you can find out for yourself. After speaking, Lu Zhisa ran away.

It's really not Lu Zhi's private secrets, he has a total of two sentences, and one sentence is widely known - three under five divided by two.

You must know that when he was in elementary school, calculators were already popular, not to mention Lu Zhi, how many of his peers can really use abacus?

Let's talk about addition and subtraction within ten, Lu Zhi's oral arithmetic is faster than using an abacus, but he really can't.

Expecting someone who doesn't know how to be a teacher at all isn't hard to be a strong man.

So Lu Zhi had no choice but to run away quickly.

"Abacus?" Liang Zhong looked at Lu Zhi's departing figure, "It's similar to arithmetic, and it's easy to carry." ”

As he spoke, he shook the abacus again, and the abacus hit the abacus, making a nice sound, "It's quite strong, and it's not easy to break." ”

"Yes, a good thing." Liang Zhong put the abacus in his arms and began to close his eyes quite satisfied.

Or it is more appropriate to take care of his eyes, he is a little short-sighted, but he doesn't want to be fashionable and doesn't want to wear glasses.

Swish~~~

Liang Zhong suddenly opened his eyes, "Speaking of which, the glasses are also from the Lu family, and according to Lu Yi, they were also invented by Lu Zhi, so this person is really powerful!" ”

The corners of his mouth twitched, and Liang Zhong showed a sneering smile, "Hehe, how can you be powerful?" Can't you be obediently calculated by us? Drink the old lady's footwashing water? ”

There is no distinction between men and women.

…………

Lu Zhi and his party are on their way home.

On the "BMW", Lu Zhi suddenly felt a little nauseous, he opened the curtains and let the majestic wind blow into the car, which was more comfortable.

"Fourth son, what's wrong?" Seeing this situation, a nursing home came to inquire.

"Your name is Sword Thirteen, right?"

"Yes."

"I'll call you Brother Thirteen in the future."

Sword Thirteen hesitated, "...... It's good. ”

Lu Zhi smiled, "Brother Thirteen, I'm a little uncomfortable, give me a drink of water from the water bladder." ”

"Okay." Jian Thirteen shouted to stop the carriage, untied the water bladder on his waist, and handed it to Lu Zhi from the window, "Fourth son, if you don't let me take a look, don't be sick." ”

"Brother Thirteen will see a doctor?"

"A little." Jian Thirteen let out a sigh, "The rivers and lakes are sinister, you still have to know more, it's not like Lu Mansion outside, it's very dangerous." ”

"yes." Lu Zhi's eyes narrowed slightly, and he probably knew why Jian Thirteen would take his junior disciples to the Lu family, Jianghu ...... Not so easy to mix.

"Okay, wait for me to drink water, you can show me."

"Okay."

Jian Thirteen got into Lu Zhi's carriage and simply took the pulse, "The pulse is peaceful, the beating is powerful, the fourth prince is in good health, there is nothing wrong." ”

Lu Zhi nodded, "Well, maybe it's just that I'm holding my breath, I just drank water, and it's not uncomfortable anymore." ”
