The next day is the first Sunday after the little one goes to school.

The little guy didn't think it was interesting to go to school and be bored at home, but with the balance bike plug road, it's different.

A group of friends made an appointment to go riding together, but sure enough, Su Yuanyuan and Wei Xiaoshuang didn't come, and the little guy didn't realize it yet.

I had a lot of fun playing training games with the rest of the children.

But because the weather was too hot, it didn't take long for me to move to an indoor playground, and there were so many children at once, how to play it was interesting.

There is a large family in the family, so naturally Fang Yuan doesn't want to take the little guy with him.

So early in the morning, he drove with Ding Heping to see Chen Chao.

Director Cai Zhongcheng, who gave Chen Chao the main knife, has already come from Coconut City, and he is an old acquaintance of Chen Chao.

It was also quite surprising to see Chen Chao, and he also knew a little about the economic situation of Chen Chao's family at that time.

didn't expect that after two years, it was him who came to give Chen Chao the main knife, which can be regarded as fate.

Director Cai came today to make a final comprehensive diagnosis of Chen Chao's body, evaluate the success rate of the operation, and reduce the risk of surgery.

Fang Yuan went to pay the remaining balance payment, and then listened to Director Cai's diagnosis with Ding Heping.

Overall, the recovery is good, and Chen Chao's original physical fitness is okay, so it is a blessing that he has not been scrapped in the past two years.

As for the specific success rate, it is impossible for Director Cai to say clearly, because there are countless risks and accidents that cannot be sold during the operation.

However, if the probability is not large, it is afraid of scaring family members or patients and does not dare to operate.

Therefore, it is generally said that if there is no accident, the probability is very high.

Therefore, Fang Yuan and Ding Heping listened to it, and this was an answer that had no reference value.

Chen Chao's mentality is very good, he has no fear before the operation, anyway, can it be worse than now?

He also joked with Fang Yuan that if the operation hung up, he would be able to justifiably repay the debt.

In addition, he could also get a billion, tens of billions of underworld coins from Fang Yuan to go to the underworld to spend flowers.

It's a lot of money, so what is there to worry about, it should be Fang Yuan who is worried.

When it was almost nine o'clock, Song Xue also came with Xiaoshan, and she would be here with her father all day today.

Fang Yuan and Ding Heping also said goodbye and left first.

Ding Heping and Li Youwei made an appointment to go diving together.

Fang Yuan didn't join in the fun, but went to the furniture market to buy a smart electronic lock.

He had never paid attention to this part before, and he was very surprised to learn about it.

In addition to the normal combination lock, there are fingerprints, voiceprints, face recognition, and so on.

It can be said that the development has been very comprehensive.

But the price of the lock is also quite expensive, I remember the kind of padlock when I was a child, it was only a few dollars.

Later, there were only a dozen bullet locks.

But now, even an ordinary anti-theft lock costs about 100 yuan, and a better one is 7 or 800.

Therefore, electronic locks are more expensive, thousands of dollars cheaper, tens of thousands of dollars more expensive.

Fang Yuan chose the most expensive one, because he was afraid that the cheap one would not be able to withstand his toss.

This electronic lock looks quite tall, in addition to supporting key unlocking, it also supports fingerprints, passwords, faces, magnetic cards and voice control.

It's very comprehensive.

What Fang Yuan wants is not these functions, but the hardware that supports them, and it is convenient to go back and make magic changes.

So when I returned home, I directly brute-force the original system.

I wanted to see what to learn from, but I found that it was very rubbish, and there was no value worth learning.

Just this thing sold for tens of thousands.

Fang Yuan suddenly felt that the smart sweeper was really sold at a conscience price.

So Fang Yuan directly formatted it, and then modified Dabai's intelligent program and wrote it in.

But the chip of the smart lock cannot catch up with the circle specially ordered from the network.

So in terms of intelligence, it must have been deleted, but its face recognition was retained, and fingerprint and voiceprint contrast functions were added at the same time.

Such a high-precision intelligent electronic lock is complete.

Fang Yuan tried it himself, and the recognition accuracy was particularly high, in order to prevent people from using the photo to open the door.

For example, when you open the door, it will make you open your mouth, blink, or nod your head, and determine whether it is a living person through dynamic capture.

In addition, in order to double insure, after face recognition, voiceprint recognition is also required, such as a password such as "open the door".

As for fingerprint unlocking, it is also combined with voiceprint to achieve the degree of double insurance.

"Your dad just changed the lock, why are you tossing this?"

Fang's mother, who was cooking rice, came out of the kitchen and asked.

"Is the rice cooked?" Fang Yuan didn't answer, but asked.

"It's already burned, just wait for them to come back and eat, it is estimated that Xinxin doesn't want to come back. Fang's mother glanced at the time.

"This thing looks pretty good, but how can I use it?" Mother Fang looked at the door lock installed by Fang Yuan with some curiosity.

So Fang Yuan excitedly explained all the functions to her.

"So you don't have to bring a key when you go out in the future?" Fang's mother said very curiously.

"Of course, high-tech is convenience. "Fang Yuan is naturally authentic.

"It looks quite smart, so is it plugged in, or is it battery-on?" Fang's mother then asked.

"On the battery. Fang Yuan replied casually.

"Then if there is no electricity, how will I open the door?" Fang's mother asked.

"Of course it's with a key?" Fang Yuan replied without thinking about it.

Fang's mother: "......." ”

"In that case, don't you still have to bring the key? Otherwise, you won't be able to get in if the power runs out one day. Fang's mother said disdainfully.

Fang Yuan was suddenly speechless, and could only say, "At least you don't have to bring a key when there is electricity." ”

"How much did you pay for this lock?" Fang's mother asked casually.

"Twenty-three thousand. "Fang Yuan is very unconfident, weak and authentic.

"What, twenty-three thousand, I can buy a door for twenty-three, you just buy a door lock?" Fang's mother said in surprise.

"Isn't this high-tech!" Fang Yuan argued.

"In order to open the door and insert the key a few times, you bought such a high-tech machine for 20,000 three?" Fang's mother said angrily with wide eyes.

"It's not for Shin Shin, it's mainly to make it easier for her to open the door. Fang Yuan hurriedly explained.

"Xinxin, when did she come back with us, we helped open the door, we are such a big living person, are we not smarter than your lock?" Fang's mother said angrily.

She felt that Fang Yuan had earned a little money, so she began to spend it lavishly, if she really wanted to buy something real, it would be fine, but a completely unnecessary door lock, hehe.......

"Mom, it's really easy to use, come, I'll help you enter the information, and then you can try it." Fang Yuan hurriedly pulled her over and diverted the topic.

"I'm very good with the key, so I don't have to use this troublesome thing. Mother Fang said angrily.

"No hassle, no hassle at all. Fang Yuan said with a salivating face.

At the same time, quickly enter Fang's mother's information.

Then he pulled Fang's mother out of the door, locked the door and said, "You look at the door lock now, and say open the door to try." ”

Hearing this, Fang's mother was a little reluctant, and said "open the door" to the door lock.

Immediately a "click" was heard, and the door opened.

"I don't think this is any different from the iron gate in the courtyard!" Fang's mother muttered.

"Mom, I'm going to call Xinxin and them back for dinner. Fang Yuan was afraid that Fang's mother would continue to speak, so he hurriedly ran away.

"Huh......" Mother Fang didn't shout, Fang Yuan had already run away.

"Really, isn't it okay to make a phone call?" Fang's mother picked up her mobile phone and called Lan's mother.

In the morning, Mother Lan and Blue Caiyi took the little one out to play.

As for Dad Fang's going to Mama Blue's new house, the main thing is to find a carpenter to get a dog house for Rhubarb, and there is also a big rooster that the little guy has to bring back, and he also needs a cage.

After finishing the call, Fang's mother put away her phone and said with some loss: "This kid, I think I'm long-winded!"
