After carefully reading the materials required for upgrading twice, Zhang Tuohai silently remembered it in his heart and regarded it as the latest stage goal.

After upgrading the vehicle, it is time to make anti-skid chains.

This thing is a slender iron chain, tied to the tire of the car according to a specific method, which increases the friction of the car and is very useful on ice.

Of course, if you drive a car with anti-skid chains and wander on the asphalt road, you are simply making yourself uncomfortable.

Someone from the road administration department will come to you for tea.

Of course, in this world, there is no road administration department to trouble Zhang Tuohai.

However, Zhang Tuohai still had to ask, otherwise, wearing anti-skid chains would greatly hinder the speed of the vehicle.

After understanding the system for a while, Zhang Tuohai found out.

Although the working principle of this anti-skid chain is similar to that of the original world, it has been upgraded to a car accessory. One advantage is that it does not need to be disassembled and installed by yourself.

When encountering ice, you only need to click a button and the installation can be completed in one second.

When it is no longer needed, just click a button and it can be disassembled in one second.

"It's very convenient." Upon hearing this, Zhang Tuohai felt that the system was very considerate at this point.

Otherwise, let him wrap the anti-skid chain by himself, and he will be too exhausted to figure it out.

Moreover, one of the more kind things about the game system is that in the production materials, the number of materials required is marked, and it does not make any difference whether you are a three-wheeled vehicle or a six-wheeled off-road vehicle.

Even if it's a 20-wheel trailer, it's still the same price to install anti-skid chains.

Zhang Tuohai is equivalent to using two anti-skid chains for nothing.

"Have I finally taken advantage of the system?"

Zhang Tuohai felt so happy that he felt like he could eat two more bowls for dinner.

After finishing making the anti-slip chain, Zhang Tuohai chose to put it away. This thing would be put to use the day after tomorrow.

Next, Zhang Tuohai took out a thumb-sized chip.

This thing is the legendary smart car control system database - the song part, referred to as the music library.

"How do you use this thing? It doesn't have a socket." Zhang Tuohai held the chip and gestured on the console for a long time, but he couldn't find a suitable socket.

"Commander, put it here~"

Xiaoai classmate pops up a slot tray.

There are 12 grooves on this tray, all of the same size.

Zhang Tuohai inserted the chip in his hand into the groove.

Pallet retracted.

[System is being updated...]

【update completed.】

"Commander, there are many new songs. Do you want to play one to try out the sound effects? (｀?ω?′)"

"Then let's play "Love 105° You", and I want Tengger's version, by the way." Zhang Tuohai said.

Classmate Xiaoai:(￢_￢)

Super idol’s smile

Not as sweet as you

August noon sunshine

Not as dazzling as you

…

Tengger's highly recognizable voice came from the player.

It was originally a sweet little love song, but when it was sung by Tengger, it seemed to have a very magical feeling, which made people want to listen to it again after listening to it once.

The cycle goes on and on and cannot be stopped.

Being able to hear this song in this world gave Zhang Tuohai an indescribable feeling in his heart.

Zhang Tuohai decided to do something.

So, he made a thermostatic bathtub.

The thermostatic bathtub is two meters long, one meter wide and 60 centimeters deep. If it were the previous car, it would really not fit in it.

However, Zhang Tuohai has upgraded the car to a level 3 six-wheel off-road vehicle, and the internal space has been repeatedly increased three times, so installing a bathtub is still not a problem.

Zhang Tuohai visually inspected the remaining space in the car and found that at least it would not be a problem to install an independent car toilet.

In order to celebrate getting the information about the next world, Zhang Tuohai decided to consecrate the newly acquired bathtub.

There was a water reservoir on the bathtub. Zhang Tuohai filled it up and then discovered that there was a thermostat on it that could be adjusted to two decimal places.

"It's quite accurate." Zhang Tuohai adjusted it to 42°C, which is his favorite bathing temperature.

After five seconds, the red indicator light turns green.

"So fast?" Zhang Tuohai opened the faucet and tested the water temperature. Sure enough, it had reached 42°C.

Zhang Tuohai was overjoyed and immediately took off his clothes and got into the bathtub.

"Hiss-hiss-oh-hiss-ha~"

When his body was completely immersed in the water, Zhang Tuohai felt as if he had been reborn.

It has been six days since he came into this world.

Although his life is more prosperous than that of most players, he is still wandering on the edge of danger every day, which cannot be compared with the peaceful society before.

What's more, the seventh day of disaster hangs high above your head like a sword of Damocles.

His nerves did not dare to relax for a moment.

Work hard to prepare for the disaster day.

Now, he is finally ready to deal with tomorrow's disaster day, and has also obtained information about the next world.

At least tomorrow, he doesn't need to worry anymore.

He could finally relax for a moment.

Soaking in the comfortable warm water, Zhang Tuohai relaxed his body, letting his body half-suspended in the water, relaxing every muscle in his body, and enjoying a rare moment of relaxation.

Classmate Xiao Ai also switched Tengger's singing to "The Original Scenery of My Hometown".

Closing his eyes, Zhang Tuohai felt as if he had returned to his original world.

I don't know how long it took.

The sound of the game system rang in Zhang Tuohai's ears.

"When the stay time is up, teleport back to the original space."

Then a white light flashed.

Zhang Tuohai opened his eyes and glanced out the window.

At this time, what was outside the window was no longer the ice cave covered with ice and snow.

He returned to the endless desert road.

Looking at the scene in front of him, Zhang Tuohai felt a little bit inexplicably reluctant. He knew that after tomorrow, he would leave here and enter a world full of ice and snow.

"Bah, bah, bah, I must have lost my mind to feel reluctant to leave this place." Zhang Tuohai patted his face to wake himself up.

However, the heat preservation effect of this thermostatic bathtub is really good. It has been three hours and the temperature has not changed at all.

Zhang Tuohai looked at this temperature-controlled bathtub with a little pity.

This bathtub can only adjust the water temperature between 0-50℃ and cannot boil it.

Otherwise, it would also be good to use as an extra large kettle.

Looking at the water in the bathtub, Zhang Tuohai put his clothes in based on the principle of not wasting.

I have been wearing this outfit for six days. It has been soaked with sweat countless times and is a little stale.

However, looking at the clothes soaked in the bathtub, Zhang Tuohai became lazy.

At home, all these tasks are done by the washing machine. When has he washed clothes?

However, he doesn’t have a washing machine now, so what should he do?
