Zhang Da said excitedly:

"My lord, not only has that thing been developed, but also the car developed by the fourth lady can also be manufactured."

"Hahaha!"

Lu Bu was overjoyed when he heard this,

Excitedly walked down from the position,

came to Zhang Da's side,

patted Zhang Da's shoulder heavily,

It hurt so much that Zhang Da bared his teeth.

Only then did Lu Bu speak loudly and say to everyone in the hall:

"I've made up my mind!"

Again return to the main seat and stand still,

Lu Bu said in high spirits:

"From now on, we will start preparing for the 'blind date conference', and it will be officially held in a month. This time, the blind date conference will be carnival during the day, and men and women can arrange their own programs, and the type is not limited. Single men and women who want to participate in the blind date conference are free to register, and this time the event is mainly voluntary. In addition, the men and women who successfully held hands at this conference will participate in the grand wedding ceremony that I presided over and witnessed. Everyone used this month's time to prepare well, and appointed Diao Chan, Zhang Ning and Gu Yong as the main persons in charge of this 'blind date conference', and there is only one request for you, to do it in the big and lively, if you can let everyone in the world know, I will be rewarded! I don't have to mention the matter of sending troops again, and I will grasp the right time! That's all for today's court meeting. ”

Lu Bu said a long paragraph in one breath,

The people below listened to it,

After a few breaths,

Immediately there was a commotion in the council hall,

Many people are still ready to continue to advise Lu Bu,

But they were all directly ignored by him,

Pulled Zhang Da and walked to the back.

All of a sudden, the uproar in the council hall intensified.

Many people gathered around Tian Feng and Fu Zhi.

Frustrated, he turned his head to look at his old friend,

Tentatively asked:

"Yuan Hao, you see?"

The two have been friends for many years,

Tian Feng naturally knew what he wanted to ask,

Shaking his head, he sighed and said:

"Alas——, since the lord has already issued an order, this must be no longer changeable."

"But, isn't this child's play?"

He spoke anxiously.

Xun You shook his head beside him,

Sigh says:

"It stands to reason that the lord is not such an indiscriminate person, how could he make such a move, isn't this a missed opportunity."

At this time, a voice came from the side,

"In the next guess, the lord must have other considerations, and let us see how things develop."

And the people went according to their prestige,

I saw that the person who spoke just now was Gu Yong.

Seeing Gu Yong coming over,

It's still in the court,

for tat frustration with him,

At this time, it was a smile,

Spoken:

"Yuan sighs, there are many offenses."

Gu Yong hurriedly saluted and said:

"Mr. Fu, why do you say this, you and I are both working for the Lord. It's just that there is a disagreement, and please don't offend the strange boy. ”

Tian Feng, Fu Zhu and others discussed with Cai Yong's peers,

Therefore, as a disciple of Cai Yong, Gu Yong,

In private, they are all respectful to the two of them.

At this moment, several people are in a harmonious manner,

There was no suspicion in the slightest because of the controversy at the time of the court discussion.

Tian Feng shook his head and said with a wry smile:

Now I can only take one step at a time, as Yuan Si said. I hope we all guessed wrong this time, if it's really unfortunate for you and me to expect, then how to fall too wrong. ”

Gu Yong said respectfully:

"Two gentlemen, I still think that there is no problem with the lord's order, and sending troops is not the top priority of our army today, in fact, if this 'blind date conference' is really successful, it will be more beneficial to our army."

"Hahaha, okay, you Gu Yuansi, then let's see. What if you're wrong? ”

Frustrated with a laugh he spoke.

Gu Yong smiled and replied:

"Listen to the gentleman."

"Good! If you lose, you will take care of me and Yuan Hao for a month's Qiongyu liquid. If you win, the two of you will take care of your Qiongyu liquid for a month! ”

"That kid is just waiting for the two gentlemen's wine."

Gu Yong bowed, and a dashing smile appeared on the corner of his mouth.

"Hahahaha, you guy!"

The group walked out of the meeting hall with a smile and a smile.

Lu Bu ran to a study with Zhang Da,

This is Taishou Fuzhong,

Where he usually works,

He was followed by two soldiers carrying wooden boxes.

When the two soldiers put down the wooden box,

Lu Bu waved his hand and motioned for them to leave,

Hurriedly asked Zhang Dadao:

"Master Zhang, is there a switch in this wooden box that regulates the flow of water?"

Zhang Da hurriedly opened the box,

There are several parts in it,

It's not small,

The smallest one is also the size of a palm.

Zhang Da explained to Lu Bu while assembling:

"My lord, since this is the first time to make a demonstration, I made this one relatively large."

In a short time, something about two feet tall was assembled.

There are three passages,

From above,

The finished glyph arrangement of the three channel mouths,

Behind are two downward passage openings,

There is only one passage in front of us,

In the middle of these three passages,

is a handle that protrudes upwards,

It looks like it can be turned.

Lu Bu exclaimed in his heart: This is no different from the tap of later generations.

It's just that the item in front of me is made of wood.

Later generations were made of stainless steel or other materials.

Lu Bu sighed and praised:

"I didn't expect it, I didn't expect it, Master Zhang, you are really amazing, you made this thing so quickly."

Zhang Da looked at Lu Bu suspiciously, and asked:

"The lord must have seen this thing before."

Only then did I realize that I had just said the wrong thing,

Hurriedly shook his head and found a reason:

"I used to dream about this thing when I was dreaming, so I was able to imagine it and tell you. Hahaha. ”

Lu Bu scratched his head to hide his embarrassment and said:

"But Master Zhang, what you did is really amazing, I really admire it."

Zhang Da held the switch with both hands,

When it was lowered to the ground, it made a heavy noise.

Lu Bu asked in surprise:

"What is this made of?"

"Ironwood." Zhang Da opened his mouth and replied:

"On the one hand, in order to ensure the strength of this object, and at the same time, considering the long-term contact with running water, ironwood was chosen."

Lu Bu nodded when he heard this.

Zhang Da then added:

"Later, I also realized that using ironwood was too heavy, so I was going to replace it with other wood."

As he spoke, Zhang Da twisted the knob of the switch with his hand,

And he found the teapot in the study,

And he poured the water into the mouth of the passage,

With the rotary switch,

The water cup in the mouth of the channel controls the descent.

Lu Bu looked at it and smiled,

Zhang Da said with a sense of accomplishment on the side:

"Thanks to the whimsy of the lord, this object sounds complicated and not easy to make, but after understanding the principle, it is really easy to understand. I am so happy to be able to make such a delicate object with my own hands. ”

Lu Bu fiddled with the switch curiously,

casually said:

"What is such an object, there are many more unexpected things that you need to make and study in the future."

Hearing Lu Bu's words,

Zhang Da's eyes couldn't help but light up,

What interests him most is to be able to invent and make a lot of new things.

Lu Bu's whimsy happened to give him room to show,

Many times some of Lu Bu's thoughts,

A lot of inspiration added to him,

Let him feel that his level is improving faster and faster,

For a person who loves his career,

It is a very happy and happy thing.

Seeing that Lu Bu was still fiddling with the switch,

Zhang Da suddenly slapped his forehead and said:

"That's right, my lord. There is also the human-powered rail car designed by the fourth lady, and the drawings I studied for a morning today, which are really exquisite. Lord, you and the fourth lady are really, really ......"

Zhang Da was so excited that he couldn't express it in words,

Excited and incoherent,

He hurriedly took out a few pieces of parchment from his bosom.

Put it on Lu Bu's desk and show it to Lu Bu.

Lu Bu looked at it,

There are all kinds of parts and components densely drawn on it.

And the data,

Lu Bu felt his head grow for a while,

Rubbing his temples,

Hurriedly spoke:

"Master Zhang, don't show me this, I have a headache."

When he looked at Zhang Da,

Eyes suddenly glanced at a drawing,

It's a piece of paper with data.

There are countless data densely recorded on it in block letters.

Lu Bu took the paper,

At a glance, I recognized that it was Ding Yao's font,

He asked:

"That's how you keep track of things?"

"Huh? By the way, is there something wrong with that? ”

Zhang Da reached out and wanted to come over and get the parchment.

Lu Bu waved his hand and said:

"That's not what you mean, that's what you wrote?"

"Of course. Isn't it possible to use some other words? ”

Zhang Da said as a matter of course.

Lu Bu shook his head and said:

"No, that's not right."

"What's wrong?"

Zhang Da asked a little nervously,

He also thought that Lu Bu was saying that there was an error in the data on it.

Seriously start the check-up.

Lu Bu raised his eyes and saw Zhang Da's appearance,

Immediately knew that he had misunderstood what he meant,

He snatched the parchment and said:

"That's not what I said."

Zhang Da looked at Lu Bu suspiciously,

Lu Bu thought for a moment,

Spoken:

"Master Zhang, in this way, you can sit here for a while, and I will find a few people to come over, and then teach you something."

Hearing this, Zhang Da sat quietly aside.

Lu Bu opened his mouth and shouted outside the door:

"Evil comes!"

Then Dian Wei's ugly face appeared outside the door.

Lu Bu instructed: "Go and invite Mr. Tian Feng and Mr. Gu Yong, and let them bring six Mr. Bookkeepers over." ”

Dian Wei was stunned when he heard this strange order,

But he still nodded, and left in a hurry.

After nearly a meal,

Lu Bu and Zhang Da discussed some details of the human-powered rail car,

A group of people hurriedly walked in from outside.

"My lord."

"My lord."

"I've seen Wen Hou."

The group saluted.

Lu Bu got up and waved his hand and said:

"Don't be polite, just now when I was discussing with Zhang Dajiang, I suddenly remembered something and wanted to tell you."

Tian Feng and the others all looked at Lu Bu seriously.

Lu Bu then spoke:

"I went to the Western Regions this time and learned a magical calculation method, which is very simple and fast, much simpler than the numbers we use now. I want to teach you this method. ”

Lu Bu stood up and said to the bookkeeper who was following Tian Feng and the others:

"The gentlemen must be good at arithmetic."

Several people looked at each other,

Then he nodded a little reservedly.

Lu Bu opened his mouth and said:

"Don't be nervous, gentlemen. So, I'll write down a few numbers first, and you'll write them down. ”

Then, Lu Bu took a pen and paper,

Write down the ten Arabic numerals from 0 to 9 in turn,

And told them their pronunciation and the numbers they represented to these bookkeepers.

Everyone felt very novel after listening to Lu Bu's explanation,

And these ten numbers are also very easy to remember.

Soon, the six bookkeepers memorized ten Arabic numerals.

Tian Feng and the other three next to him,

I also learned to memorize it.

After Lu Bu saw that everyone had memorized these ten Arabic numerals,

Nodding, Lu Bu spoke again:

"What I just told you is ten Arabic numerals, which have the same meaning as our Chinese characters from one to zero. I'm going to tell you a little bit more about the four algorithms. ”

Lu Bu then drew the four symbols of addition, subtraction, multiplication and division on the drawing.

This symbol is a plus sign, which indicates the addition of two numbers; This number is minus......"

This time Lu Bu spoke very carefully,

and afraid that they did not understand,

Explained again,

Until everyone nodded their heads to understand,

Only then did Lu Bu stop.

Finally, he taught the people the equals,

And then he wrote down several equations,

Demonstrate this calculation directly to the crowd.

Since these are very simple basic laws,

These people are the leading bookkeepers.

Understanding and learning these foundations is naturally handy.

Let these bookkeepers also demonstrate themselves a few times,

After nothing goes wrong,

Lu Bu nodded with satisfaction.

"It's good, everyone learns very fast. In this way, let's verify on the spot which way is faster. ”

The others, after hearing Lu Bu's words,

They all nodded in agreement,

They've all learned this way of calculating.

But I think it's pretty good,

But after all, I haven't tried it,

Whether it's good or not, we still have to speak with facts.

The six bookkeepers were divided into two groups,

A set is calculated in kanji,

A set with Arabic numerals,

And then in transposing,

After many trials,

Everyone recognized the convenience of this method of calculation.

"Well, isn't it a great way to calculate. Mr. Tian, Yuan Si, Zhang Dajiang, whether it is people's livelihood or craftsman camp, many of you need to use arithmetic, and I specially teach you this method, just to hope that you can promote it, so that you can use it in many aspects in the future. ”

Everyone present immediately understood what Lu Bu meant,

All overjoyed,

With this kind of number instead of complex Chinese characters for recording,

I don't know how much trouble I'm going to save.
