Granddad's cabin No, the big house has four floors, two floors above the ground and an attic, and a cellar room under the ground.

Lu Zhengkang's bedroom is arranged on the second floor. The corridor of this floor is in the middle, facing north and south, with master bedroom in the East and two guest bedrooms in the West. However, it is used to store sundries. Lu Xuefeng cleaned up an hour and three minutes before he ordered out a decent room. When he first entered, Lu Zhengkang even saw a pile of fat rats rolling round in the corner of the wall. In the dark room, his green eyes were staring at Zu for a moment Sun Liang is not afraid of people at all.

After cleaning up the bedroom, Lu Xuefeng buried the mouse body with thick ash in the mud at the door.

When the old man was busy, Lu Zhengkang noticed that there were tattoos on his back, sweat, white shirt and flesh, and large tattoos were looming out.

Lu Xuefeng turned around and gave him a smile, "son, wait a little longer, I'll get you a mattress."

Lu Zhengkang was stupefied, a little confused, and his mind was full of thoughts.

What's the way of this granddad?

Lu Xuefeng took the mattress from the attic. It's an old mattress. It's not uncommon, but it's not everywhere. Now people sleep at home with cushions are high-grade goods, not only the temperature is controllable, but also has massage function, can also concave fit the curve of the human body soft pit, let the sleeper as if in the cloud. In Lu Xuefeng's hand, the outer skin is camouflage. It should be a traveller's sleeping mat. It's just a bundle when rolled up. It can sleep one or two people when spread out.

It was very popular twenty years ago. When people were rich, there were more donkey friends.

The 20 flat guest bedroom is packed with broken wallpaper, the furniture is wiped with a wet rag, the air conditioner is used for ventilation and dust removal, and finally it is a very good room under the soft light.

Lu Zhengkang officially checked in with his bags.

Today is Friday, January 16, 2082, December 18.

Lu Zhengkang lay on the bed for a while. The bedding was cool. Fortunately, it wasn't damp. It should have been dried. As long as it wasn't damp, it could always cover the heat. There is an air conditioner in the house, but the heating is not enough. There should be something wrong with the air conditioner. It's buzzing during operation, which makes people suspect that there are 1000 bees flying around in their ears.

Look at the time. It's almost two o'clock in the afternoon. Lu Zhengkang opens his mailbox and has no news.

Why duck?

You guys forgot about us? Oh, they are traveling. Maybe they are in the middle of the journey now. They are very busy.

But my parents? They don't comfort us! Is it hard to drink forget baby milk?

Lu Zhengkang laughs when he thinks about it. Anyway, he has nothing to do. He takes out the VR device and starts online classes.

The art class he signed up for uses virtual Sketchpad to draw on the Internet, which requires VR, that is, virtual reality equipment, a pair of headwear glasses and a pair of handles. This kind of technology has been developed for more than half a century, but it is still not out of the rut.

When using VR, the biggest concern is that the user's environment is limited. Although the current algorithms add non Euclidean geometry, which can compress a large amount of virtual space, so that the user can visit a large area in a relatively small environment, this is a temporary solution but not a permanent solution.

Now it is said that the breakthrough of VR lies in neural connection, which directly converts digital signals into neural signals to the brain, so that people can enjoy the immersive experience in sleep.

Unfortunately, the VR simulation cabin scam that shocked the world at the beginning seriously dampened the public's confidence, leading to the underinvestment of technology companies in this field, bankruptcy and transformation. It is said that several of them have switched to the direction of food.

However, there are always large companies insisting on it. Almost every three or five days, we can hear that XX laboratory has a new breakthrough in the VR field, and the heat is still high. Maybe one day when we wake up, we will find that the simulation module is officially on sale.

Lu Zhengkang put on his flimsy VR glasses and saw a piece of beach in the early morning. There was a hazy white light on the horizon in the distance, while the sky was a picture of deep space simulated by software. The famous Crab Nebula cruises in the southeast of the sky. The Milky way is high and colorful.

Here is his own set of operation interface, click open online course software, start a new day of learning.

Learning is really a pleasure That's bullshit.

Lu Zhengkang scribbled over and over again, then deleted and started again.

If only my system is the kind of stupid operation that people can learn without learning? It's a pity that even if you study with a little savvy, you have to practice hard over and over again. And talent is really important. Without that talent, no matter how long you practice, you won't have any problems.

The only advantage is that the skills trained by the savvy point will not be forgotten by the body. That is to say, after Lu Zhengkang has learned the modern fighting skill, even if he doesn't practice it for ten years, he can still do it with the same agility as long as he has enough physical quality. Routine will not be forgotten, but body function will decline.

In the same way, if he learns a language with his savvy, even if he doesn't practice it for several years, he can still speak well as long as his voice is not bad and his tongue is not broken.

Ding -

when Lu Zhengkang carelessly draws lines, the system suddenly pops up a message to check the system in VR, giving him the illusion of Russian dolls.Look at the news. I didn't expect that the one who cares about Laozi most these days is a broken system.

"You have a new specialty."

Oh, Ho, surprise. Let me see what the most intimate small system can bring

Wishful thinking (rare): you often have some ideas that are out of line with the times. Combined with your extraordinary early wisdom, you give the impression that you are a dreamer who likes wishful thinking.

Effect: personality charm increased slightly, nonlinear thinking strengthened.

Lu Zhengkang: Thank you so much!

Xiaolu was so angry that his hands trembled. He suddenly drew a good curve as Picasso's abstract painting. He was so angry that he left the virtual Sketchpad far into the sea. You are a little broken system. Who gives you bad habits and how to comment are all weird. Is it the legendary Maoming Yin Yang master hiding in the system?

Online course software warning: "please continue to learn, your behavior will be recorded by the system."

Lu Zhengkang was silent for a moment, and then he pointed out a sketchpad.

Learning is a very high pressure thing.

All afternoon, Lu Zhengkang practiced painting for two hours, then watched popular science drama for one and a half hours. At half past five, my grandfather knocked on the door.

Lu Xuefeng didn't wait for Lu Zhengkang to open the door, just said a word to eat, and then went downstairs.

Lu Zhengkang ran into the living room, only to find a guest at home.

A tall and thin young man with a scratchy beard was sitting on the dining table. His greasy long hair covered his head like a deer hunting hat. He was holding his rice bowl and was rowing in the electromagnetic cooker with chopsticks. The strong smell of mushroom rushed to Lu Zhengkang's nose. He swore that he had never seen such a disgusting and rude person.

How can there be a guest who can cook without waiting for the host?

The young man turned to see Lu Zhengkang and gave him a smile. He was a bit shy, which was totally inconsistent with his bold behavior. However, as soon as he opened his mouth, he revealed his quality. "Kid, come to eat. Let's eat first. Let's starve your grandfather to death."
