"This algorithm is too rudimentary."

Fang Tianfeng shook his head slightly and said helplessly, "I'll teach you a method that can calculate quickly and make it difficult for others to understand."

In fact, the abacus is sometimes more useful than the computer. In the past, the calculation of the nuclear bomb in Huaxia was carried out with the abacus.With the abacus and formula, Lu Zhi can calculate the desired number in a short time.

Coupled with the help of Arabic numerals, even if the account book is given to others, the other party will not be able to understand.

It can not only ensure the efficiency, but also ensure the security of the account book, and will not be tricked by others.

"Ah, thank you husband."

Lu Zhi's face was happy, she never doubted anything Fang Tianfeng said.

"But before that."

Fang Tianfeng suddenly made his move, picked up the girl in front of him by the waist, and walked towards the bed in the way of a princess hug.

"Husband, husband."

Lu Zhi is no longer an ignorant child. With her pretty face flushed, she knows what will happen next.

……

Lu Su is very strange, if my sister wants to find her, she can come directly.

Although Lu Mansion is not small, it is not big either. Her and Lu Zhi's room is not far away, and the two sisters have a good relationship and often sleep together.However, today Lu Zhi asked a maid to inform her.

The maid did not dare to lie, even if she was given ten courage.

Although Lu Su is a little quiet, she is after all a lady from a scholarly family. This is a fact that cannot be changed.

"elder sister."

Lu Su knocked on the door of Lu Zhi's room, and she heard gasps from the room.

Although it was very weak, she could hear that it was her sister's voice.

Both she and Lu Zhi belonged to their daughters, and the courtyard was divided for them separately.Therefore, except for their two sisters and the cleaning maid, no one else is allowed to enter here.

Therefore, no matter how loud it is, no one will hear it.

"Crench--!"

The door opened, but it was not Lu Zhi who appeared in front of Lu Su, but Fang Tianfeng who was naked.

"Husband, husband."

Looking at the towering thing, Lu Su couldn't help but feel hot.Subconsciously, he turned around and wanted to leave.

However, since it is here, it is not so easy to leave.

Before Lu Su could take a step forward, Fang Tianfeng hugged him back and carried him directly into the room, closing the door.

Then, Lu Su saw Lu Zhi who was panting heavily on the bed, as if he was tired from strenuous exercise and had no strength at all.

"Sister, what happened?"

Lu Su became worried all of a sudden, she thought that Lu Zhi was sick.

But it's not like, how can anyone get sick without wearing clothes?

"You'll find out soon enough."

Fang Tianfeng lightly touched the girl's earlobe, and then began to undress very skillfully.

……

"Guest officer, what would you like to eat?"

Fan Kuai looked at the young man in front of him with a pleasing smile, but he was a little puzzled why the other party's chin was so clean and hairless.Could it be that he has been tortured?

Most of the people who are tortured are fighting to make the other party too serious, or beat their wives to death.

"Of course it's dog meat!"

Yi Xiaochuan had a proud look on his face, but he didn't know that at this moment, someone behind him was already staring at him.

Chapter 049 Mobile phone sees mobile phone again (for collection)

Fang Tianfeng was planning to go to Xianyang, but he saw Yi Xiaochuan on the street swaggering across the city on a horse.

So, he dismissed the idea.

Instead, he turned around and went back to the mansion, and then gave Lu Zhi and Lu Su the grass.

But this is not enough insurance, that unscrupulous spicy chicken father-in-law, it is estimated that he may cheat himself.

So I have to stay for a few more days until Yi Xiaochuan and Liu Bang are gone.

Fang Tianfeng asked the county magistrate, and in a few days it will be the day when the chiefs of the pavilions from all over the world will take the Qianshou to Xianyang to serve corvée.Therefore, Liu Bang will definitely take people to Xianyang, and Yi Xiaochuan is also someone who can't be idle, so he will definitely go with him.

So, just wait until they leave.

"Pheasant, can you draw?"

Fang Tianfeng was lying on the bed, hugging from left to right, but suddenly asked.

"I'm sorry, husband."

Lu Zhi shook his head apologetically, his tone full of guilt, "I, I haven't learned these skills, but maybe a little bit faster."

This is a lie, and if Lu Zhi doesn't know Lu Su, he won't even know it.It's just that because she's already in the limelight now, she doesn't want her sister to become weak, and wants Fang Tianfeng to pay more attention to Lu Su.

"Well, it's fine."

Fang Tianfeng nodded, then sat up and took out his mobile phone from his pocket.

A lot of data in this old phone has been transferred to Xia Wei, and some of Gao Lan's artistic photos have also been deleted.Now, there are only some videos of advanced knowledge left in it.

Also, a group photo of Fang Tianfeng and Gao Yao.

As Gao Lan's elder brother and Fang Tianfeng's brother-in-law, it is normal for Gao Yao to take a picture.

"Susu, can you draw this person?"

Fang Tianfeng pointed at Gao Yao on the phone screen and asked softly, "It's very important, it's best to do it as soon as possible."

"Husband, husband,"

Lu Su's eyes were filled with sparkling tears, "I, I won't."

"let it go."

Fang Tianfeng shook his head, and then directly put the phone to Lu Zhi and the power bank.

"Husband, this..."

Lu Zhi held the phone in surprise, but she knew that this thing was a rare treasure.After so many days, she has basically figured out how to use this mobile phone, but how could this kind of baby be given to her?

"It's for you."

Fang Tianfeng said without hesitation, "Also, if there is no electricity, you can use this cable to connect this phone to that cube to charge it."

"Husband, I, I can't have it."

Lu Zhi was moved, but struggled very much. He bit his lower lip and finally refused, "Husband, you need it more than I do. If I'm just at home, I don't need this."

"Don't worry, I have something better."

Fang Tianfeng shook his head and hugged the girl gently, his voice soft and warm, "There are still many videos in here, you can take a moment to watch them, there may be some things in them that you may need. But you don't have to work too hard. Paper is enough for us to make a lot of money.”

"Ah."

With a sour nose, the girl couldn't help crying.After so many days, it's not like she doesn't know Fang Tianfeng's net worth, where is there any other better phone besides this one?

Married like this, what can a concubine ask for?

"Don't move, have a good rest."

Fang Tianfeng looked at the girl who was struggling to get up and couldn't help feeling a little guilty, and quickly held the girl down.I have always attached too much importance to Lu Zhi, and somewhat ignored Lu Su.

Even the mobile phone is enough to subconsciously give Lu Zhi.

However, the rain and dew were all wet, and it was not a good thing for Lu Zhi but not Lu Su.

So, he put his hand into his pocket again, pretending to be picking something.But it was using the deformation function to create a mobile phone exactly like Lu Zhi's for Lu Su.

"Susu, this is yours."

Fang Tianfeng handed the phone to the girl, and looked at the girl's moved appearance and felt a little guilty, and quickly said, "Let's have a good rest today, I still have a few things to deal with."

"Ah."

Lu Su nodded lightly, the tearing pain really made her feel uncomfortable.

Fang Tianfeng quickly put on his clothes and went out, closing the door. He still has things to do.

In the room, Lu Su's expression darkened, "Sister, am I very useless? I can't even complete what my husband ordered."

"Silly girl, your husband is distressed for you."

Lu Zhi helplessly hugged his sister and comforted her softly, "Besides, my sister doesn't know how to draw, it's alright."

Fang Tianfeng soon came to the main hall, but he forgot.

In this age when there is no papermaking technique, how could there be any ladies who can draw?

In fact, the status of Baigong in the Qin Dynasty was not high at all.And people who can paint are not calligraphers now, but painters, one of the hundred craftsmen.

What does it mean?The mason is also a hundred craftsmen, and the status of the painter and the mason is the same.

Moreover, Baigong and these things were selected from slaves and Qianshou forcing them to learn, and no one would take the initiative to learn these things.

In this era, reading and writing are still the most important thing. Even if you learn all these underground skills, it is useless. Slaves are still slaves.

And Lu Zhi and Lu Su are both ladies, how could they take the initiative to learn to draw?

So, this plan can only go bankrupt.

And in fact, apart from Xianyang, I am afraid that there is no one who can paint in the world.

In this era, although there were wanted orders, there were no wanted portraits. They used bamboo slips and wooden slips to write the criminal's information, such as appearance characteristics and the reason for the crime.
