After some exploration, Wang Wei discovered that the appearance of the light curtain was related to the tattoo bracelet on his hand that others could not see.

The key at the top of the bracelet is the key that opens the light curtain.

As for the following, after Wang Wei's experiment, we found that the light curtain is expanded and reduced, and the shape, position and distance of the light curtain are changed. Then, some keys operate on the light curtain interface.

Of course, Wang Wei also tried it. The operation of the light curtain is not only with the keys on the tattoo, but also with your hands to touch it. It is as simple and convenient as a smartphone, but there is an extra choice for the tattoo keys.

There are basic information such as time calendar and weather on the light curtain.

Looking at the calendar marked March 25, Wang Wei couldn't help but feel a little confused.

Before the time travel, he clearly remembered that it was October 22, but the calendar span on the light curtain was a few months away.

He speculated three possibilities in this situation.

First, I have been traveling through time for several months.

Second, during the time travel, the date was disordered and errors were generated.

The last possibility is that the time displayed on the calendar is not the time on earth, but the time of this world.

Wang Wei also felt that the last one might be the most reliable.

Because the time display next to the date also proves this, it happened to be 9:45 in the evening.

The clear weather and the twelve-degree temperature are even more consistent with the current situation.

In addition to these basic displays, there are many app icons on the light screen that Wang Wei is familiar with or unfamiliar with.

The first one is the icon of a certain degree that is shaped like a bear's paw and is known for its powerful search function.

The second icon is a note, which is a short video of a certain sound on the earth.

The third icon is a small shopping cart shape, but fortunately it was not a Taobao in the previous life.

As for the back, there are many icons, but those icons are displayed in gray, and outside the icon, they are displayed with words that have not been unlocked.

Wang Wei tried to click on the ununlocked icons, but there was no response at all.

Then, he turned his eyes to the certain degree icon in front of the light curtain.

After hesitating for a long time, I pressed my heart with a trembling heart.

You will know if it's a certain degree.

To be honest, a certain degree provides considerable convenience to the lives of modern people to some extent.

To know something, just move your fingers.

From astronomy and geography to trivial matters, there are few things that it does not know about.

If a certain degree on the light curtain is sure to be useful, then Wang Wei is not afraid of not being able to survive in this primitive world.

I don’t know how to burn pottery, smelify iron, and plant these things, but I can ask a certain degree.

Detailed tutorials can be found above for each.

When he opened the browser, Wang Wei closed his eyes because he was afraid of seeing something that disappointed him.

Then a crack opened the corner of his eyes and looked towards the light curtain.

In an instant, his eyes widened and his face looked ecstatic.

Opened!

The browser is actually open.

With excitement, Wang Wei typed a few words on his browser.

[What should I do if I travel to the primitive society?]

He typed the Enter key with anticipation. Wang Wei thought he would enter the search interface, but he didn't expect that when the screen turned, a few big words appeared on the screen.

[Insufficient traffic, please recharge!]

Wang Wei was stunned for two seconds, his mouth opened, and his heart suddenly sank to the bottom of the valley.

I thought that if I escaped from the earth, I could get rid of the problem of insufficient traffic by the end of the month.

Who would have thought that even if you escape from the Milky Way, you would still be controlled by the three major communication companies?

But by the way, I have become a primitive person, so where can I have money to recharge!

After clicking the screen muffled, Wang Wei entered the recharge interface.

After glanced at the balance, Wang Wei was surprised to find that his balance was 10.1 yuan.

After thinking for a long time, Wang Wei realized that when the old man sold his bracelet before traveling, he said it was a 9.9-inch sale, and he gave him twenty. As a result, he came here before he had even found a change.

The extra ten yuan and one cent should be the change money, and now it has become your own balance.

During this short period of time, Wang Wei felt like he was riding a roller coaster, with orgasm one orgasm after another ups and downs.

No matter what, it is good news to have money on your bracelet.

He checked the traffic packages and finally found that ten yuan was only enough to buy a traffic package worth ten yuan.

Without any hesitation, Wang Wei directly clicked to buy.

After seeing the balance change, Wang Wei returned to the browser again.

After re-entering the search content, Wang Wei typed the Enter key again.

But to his surprise, the search content did not pop up, but a prompt box popped up.

[Detected that the balance is insufficient and the traffic is limited, it is recommended to use the traffic to upload videos first, earn money, and then search.]

[Tip: If the balance is not enough to purchase a traffic package and the traffic is used, most of the functions of this product cannot be used, and subsequent functions cannot be unlocked.]

[ps: You can open a short video of a certain audio and upload a short video for fifteen seconds. The number of views and the number of likes will be directly converted into balance. If there is any reward, this product will charge a fee of 50%, and the rest will be converted one to one.]

[Friendly Tips: In view of many factors such as language, humanistic environment, and living habits, the content you search with this product will be based on the Chinese search content of the planet numbered dguien58656213 (after all, you can't understand the language of searching on other planets). In the future, it will be called Earth according to your language habits.]

[Note: The distance between the earth and this planet is too far away, and the traffic consumption is quite large. Therefore, it is not recommended that you use this product to watch movies, watch TV series, listen to music, etc. If you force it, the traffic consumption will exceed your imagination!]

After carefully reading all the prompts, Wang Wei spent almost two hours studying a short video of a certain music video and the last unlocked icon shopping cart, and finally figured out the function of this bracelet.

For now, this bracelet has only three functions.

The first is to use the browser search function to obtain the knowledge you want.

The second is to shoot videos and upload them to a short video of a certain music video. You can make money by likes, browsing, rewards, and comments, and the money will directly become your own balance, but it is not clear how much a like can be converted into.

The last function is the shopping cart.

In the shopping cart, you can buy everything that can be made by the current social civilization.

Simple ones such as stone axe and wooden spear.

More complex things are like waterwheels made of pure wood, horse-drawn carriages, etc.

Even food can be purchased directly. The processed fish and venison look delicious, making Wang Wei salivate.

However, all metal objects and ceramic products do not exist, perhaps because he has not mastered the methods of smelting metals and burning pottery for the time being.

The products inside made Wang Wei dizzy and drool.

But one drawback is that those things are not cheap.

An ordinary stone axe costs dozens or even hundreds of dollars depending on the shape and size.

A short bow of one meter costs hundreds of yuan.

In the end, Wang Wei reluctantly turned off the light curtain, afraid that if he continued to watch, he would get red-eye.

After all, most of the things in the shopping cart are bought by me in a hurry but I don’t have the money.

When he was on Earth, Wang Wei was a poor man.

When he arrived in this world, he thought he would get rid of the troubles of money and create happiness with his hands.

But when he opened the bracelet, he found that he was poorer than on earth.

Wang Wei studied this bracelet for several hours. When he looked up at the sky again, the moon had passed the peak of the mountain that Wang Zhuang said.

The bonfire was much smaller, and many tribe members curled up tightly in their sleep.

After looking around, Wang Wei found a thick wooden stick and pulled out the beggar fish that had been burning in the fire for several hours.

While adding firewood to the fire, wait for the soil outside the grilled fish to cool down.

The temperature is very low now. After only ten minutes, the soil on the surface of the grilled fish became cold.

Wang Wei walked to the lower vent and gently knocked it with a stone. The crispy soil instantly fell off in one piece, revealing the hot fish inside.

From the cracked hole of the mud block, a white mist rushed out.

What I brought was also the aroma of grilled fish.

This fragrance is fatal to hungry people.

The fish was burned in a bonfire for a full few hours.

With the protection of soil, the water is locked to a certain extent, and there is no situation where the grilled fish turns into coke.
