Datang: Time travel in two months, wait online, hurry up!

At the same time, Wu Meiniang gave the answer almost at the same time as her.

The two said the answer at the same time, and the answer was the same!

When Xie Quan heard this answer, he couldn't help being slightly taken aback.

He is still calculating, why did these two people give the answer so quickly?

"Write down your problem-solving ideas on paper."

Li Ke glanced at the two with satisfaction, and asked them to write down their thoughts on paper.

As for Xie Quan, let's put aside the mental calculation.

Soon, the two of them wrote down the idea of ​​solving the problem.

Li Ke glanced at it, and the two of them had the same train of thought.

And it is the simplest and most direct way of thinking.

At this time, Xie Quan also thought of the answer.

"Your Highness, Old Man Liu has lost 90 coins!"

The number Xie Quan calculated was different from the two, but 90 Wen.

"Tell me about your thinking."

Li Ke glanced at him, and it took so long to calculate a wrong answer.

Thinking that his business had been handed over to such an unreliable person, he couldn't help but feel a little speechless.

"Old man Liu bought 30 Wen for his shoes, found a shoe buyer for 30 Wen, and returned Old Man Zhang's 50 Wen, but there is still 20 Wen left in the change, so we only need to get another 30 Wen."

"30 Wen plus 30 plus 30 Wen equals 90 Wen."

"So, Old Man Liu lost 90 Wen in total."

Xie Quan expressed his thoughts a little unconfidently.

After all, Xie Wan'er and Wu Meiniang's answers were different from his.

It doesn't matter that Wu Meiniang is different, the main thing is that Xie Wan'er's answer is different from his!

Xie Wan'er's business talent is far inferior to his, so he is a little bit unconfident.

"Xie Quan, I don't know what went crazy before, but I actually entrusted you with the tea business."

Li Ke shook his head suddenly, as if he had some self-doubt.

"His Royal Highness, Father just didn't turn the corner."

Xie Wan'er immediately explained to her father Xie Quan.

"Look at your daughter's train of thought."

Li Ke gave Xie Quan a look at Xie Waner's problem-solving ideas.

After Xie Quan read it, he suddenly realized.

Immediately, he was so ashamed that he dared not look at Li Ke anymore.

"Let me talk about your thinking first. The purchase price is 30 renminbi, and the change is 30 renminbi. This is no problem, but you must pay attention, the change money is 50 renminbi obtained from the old man Zhang with a fake check!"

"That is to say, I was using old man Zhang's money to make change, so the 30 coins should be removed from the money that old man Liu lost."

"Remove this 30 coins, and Old Man Liu actually loses 60 coins."

Li Ke shook his head and explained the correct answer to Xie Quan.

"It's the villain who is stupid."

Xie Quan was ashamed, he just missed this point.

"Of course, even if you didn't miss this point, if you answered 60 essays on this exam question, you still wouldn't be able to pass it."

"Because what this king wants to test is not the answer, but the idea!"

Li Ke was not looking for an answer, but wanted to see the simplest and most direct way of thinking.

"You need to remember that money is constant. It is just so much money. It doesn't increase or decrease. If you earn, you will lose. If you earn, you will lose as much."

"The person who bought the shoes earned 30 renminbi for a pair of shoes and 30 renminbi for change, so he earned 60 renminbi."

"Old man Zhang exchanged 50 Wen for a fake check, and then old man Liu returned 50 Wen to him. He neither made nor lost."

"Then there is only one left. The shoe buyer earned 60 coins, so the old man Liu naturally lost 60 coins."

Li Ke said the correct way of thinking.

The money will not increase, as much as you earn, he will lose as much.

This is the simplest and most direct.

Both Xie Wan'er and Wu Meiniang were thinking this way, so their answers were quick and accurate.

What fake checks, what change, what lost money.

It's all smoke bombs, it's all twists and turns.

As long as you have a strong logical judgment ability, you can see through these smoke bombs at a glance.

Find the most core and fundamental information.

"Your Highness, the villain has been taught!"

Xie Quan really realized it, and at the same time felt that he was too ashamed.

A person who has lived and been in business for so many years.

Even worse than the two girls!

Xie Wan'er is his daughter, he already knew that Xie Wan'er was very smart, so he didn't feel ashamed.

But he had never seen Wu Meiniang before, and she looked younger than his daughter, but she was able to give the answer at the same time as Xie Wan'er.

It made him feel so ashamed.

As expected of the people around His Royal Highness King Wu, there really are no mortals!

"Okay, you should pay more attention in the future."

Li Ke waved his hand, this thing is talent.

"Miss Xie will stay by my king's side from now on."

Now that Xie Wan'er has given the answer he wanted, she is naturally qualified to stay by his side and become a female secretary.

"Thank you His Highness King Wu!"

Xie Quan and Xie Wan'er immediately expressed their thanks.

Afterwards, Li Ke had someone move another desk into his study.

Yesterday, I moved a desk to Wu Meiniang for her office use.

Unexpectedly, another Xie Wan'er came today, so naturally another table had to be added.

Just like that, sitting in the study.

Li Ke sat at the main seat, and Wu Meiniang and Xie Wan'er sat at two tables on either side.

The atmosphere in the study suddenly became subtle.

Wu Meiniang and Xie Wan'er couldn't help but glance at each other, and they both saw fighting spirit and dissatisfaction in each other's eyes.

Obviously, both of them saw the other's mind.

Don't you just want to enter the palace?

Don't you just want to be Li Ke's side wife?

Since everyone has the same purpose, they are naturally competitors!

Both of them secretly made up their minds in their hearts. In the future work, they must perform better than each other!

"You should deal with these matters first, and ask the king if you don't know what to do."

Li Ke directly threw a bunch of documents to Xie Wan'er.

These are various reports from various industries.

He used to read it by himself, but now that he has a female secretary, it is natural for the female secretary to go through it first.

Filter out the most valuable information, and then he will look at it.

This will not only not affect the industry, but also save him a lot of time and energy.

"Yes, Your Highness!"

Xie Wan'er nodded seriously immediately.

Fighting is fighting, fighting is fighting, don't take Li Ke's words as a joke!

She still understands this truth.

Once he disappoints Li Ke at work, he will probably be kicked out directly.

Therefore, she will complete the tasks assigned by Li Ke with great care.

Moreover, as soon as Li Ke came up, he gave her these confidential documents to handle.

It also showed Li Ke's initial recognition of her, and she couldn't live up to this trust.

In this way, Li Ke has two more female secretaries with extremely good looks and high IQ beside him.

With the assistance of these two female secretaries, he felt a lot more relaxed these days.

"It seems that I need to train more helpers. I just need to control the overall situation by myself."

Li Ke had a rare few days of rest, and accompanied Zhao Nanyan to have a good time in Chang'an City.

He also personally experienced the feeling of hunting on horseback.

Before, at least he fell and hit his head while hunting.

But now, with the saddle and stirrups, he is much more stable on the horse.

However, he didn't have the archery skills he could inherit from his original body, so he returned empty-handed.

But he doesn't care, hunting doesn't have to be prey, just be happy and relax.

"Husband, you can't say that you went hunting today."

Sitting in the carriage, Zhao Nanyan covered her mouth and smiled softly.

Hearing this, Li Ke couldn't help shrugging his shoulders, looking indifferent.

As for bows and arrows, he hasn't had much contact with this thing in modern times.

Moreover, modern bows are all compound bows, which are too complicated in structure and have too many parts.

Before he crossed over, some netizens really mentioned the compound bow.

He also looked at the drawings and principles of the compound bow in the follow-up.

It is also necessary to install pulleys on the bow to save effort.

If it is made, it is indeed a very strong bow, but the difficulty is a bit high.

"Forget it, when the time comes, draw the blueprint and find a group of people in the Ministry of Industry to study it."

Li Ke's attitude towards this is actually indifferent. If you can do it, you can do it, and if you can't, it's okay.

Anyway, his army will definitely use muskets and artillery in the future.

It's all hot weapons, who is still fighting with you?

Sir, times have changed!

After the carriage returned to Chang'an City, it drove on the street.

Li Ke suddenly saw a group of Tubo people through the window of the carriage!

The reason why they can be recognized at a glance is that their costumes are obviously different from those of Datang.

Moreover, Li Ke noticed that these Tubo people seemed to have a high status, and people from the Ministry of Rites were receiving them.

He thought, wasn't everyone planning to fight some time ago?
