Wan Lin's eyes rolled, his minecart has brakes, as long as it goes down slowly.

The silvery-white dot of light below maintained its brightness, not a single flash, maybe it was a treasure chest, maybe it was an ore, but no matter what, it must be a good thing!

Wan Lin began to pack up the things on the minecart, put the level 3 mine mining blueprints, pens and notebooks into his bag, and then fastened two safety belts from both sides.

One is the strap type and the other is the shoulder fitting type.

Even if the entire minecart was flipped over, Wan Lin would not fall out of his seat.

Such a harness is stronger than the one tied on a roller coaster.

After everything was ready, Wan Lin put down the handbrake, put his foot on the brake, and began to slowly drive out of the platform.

This track is bent downward, and there is an almost 90-degree vertical track section, which makes Wan Lin's heart pound.

It's a veritable cave coaster!

Fortunately, this minecart does not roll on wheels, but is powered by levitation.

Unlike ordinary minecarts, the minecart touches the track and is assembled directly with the track using fully enclosed track technology.

The track is also different from the normal track, the two sides of the track are round, just fitting the original wheels of the minecart, and one carriage has four round wheels, and the track just passes through the circular hole.

Coupled with the drive of suspension power, this minecart will not have the idea of overturning at all.

Wan Lin sat in this minecart, his mood began to get nervous, his hands holding the steering wheel were a little trembling, and his feet were a little soft when he stepped on the brakes.

This matter must not be known to others, he is such a big man, he is afraid of riding a roller coaster.

Wan Lin gritted his teeth, this short section of the road slope is relatively small, followed by an almost vertical downhill, and the speed of the minecart is slowly accelerating.

Wan Lin was shocked, and he braked suddenly, and instantly stuck on the corner of the slope, he looked at the vertical track below, and 10,000 grass and mud horses were galloping in his heart.

However, through the track, he could see some reflections of the ground faintly below, and the silver-white point of light before was a little farther away, so he couldn't see it clearly.

Wan Lin was tied to his seat, and because of this pause, he slightly relieved the panic in his heart just now.

But when he didn't see the silver-white light spot clearly, he was anxious and wanted to go down to see, but as soon as his feet were so loose, the whole minecart went down with a "whoosh"!

"Ahh

Wan Lin's sour screams resounded through the mine, accompanied by the sound of steel hitting "ping", "ping", "banging" and "qiang".

Wan Lin's face began to deform slightly in the rushing wind, which caused him to react from screaming and fear, and slammed on the brakes again.

The entire minecart stopped as if it had been stuck.

Because Wan Lin was firmly tied to the seat belt, coupled with the impact of inertia, the bread he ate and the water he drank just now had already gushed into his throat.

That is, he is now so far beyond the physique of ordinary people, and it is strange that he has changed to ordinary people, and at such a speed, he brakes suddenly, and he vomits blood!

Wan Lin quickly pulled up the handbrake with one hand, unfastened his shoulder-mounted seat belt, and suddenly lay on the side of the minecart and began to vomit wildly.

After relieving the strength, the next journey, Wan Lin didn't dare to be careless, after putting down the handbrake, the brake was always stepped on, but he didn't step on it, loosen a little, loosen a little, and slowly went to the bottom.

It was already the bottom of the cliff before, and there is a fault in the cliff here, how deep this mine must be!

Wan Lin sighed, and after the front party had already touched the track at the bottom, he finally breathed a sigh of relief.

What about the silvery-white point of light? Where is it?

Wan Lin raised his head and immediately paid attention to his surroundings, and there were some lights hanging on the walls around him.

He saw a chest on top of a small stone platform on the opposite wall.

It's just that it's not a copper box, it's a silver box, a silver-white box!

Wan Lin immediately took out the level 3 mine mining drawings, pen and notebook, recorded the route just now, and then looked at the surrounding route revealed on the drawing.

I found a route through the small stone platform and drove over it as fast as I could.

Wan Lin pulled up the handbrake, unfastened the strap-on seat belt, jumped out of the minecart, and ran towards the small stone platform.

The silver-white box was still unlocked, and Wan Lin slowly opened the box and found two things from inside.

"Ding! Congratulations on acquiring Level 3 Growth Liquid*1 and Telecommunication Chip*3! ”

Wan Lin had a shocked look on his face, Level 3 Growth Liquid?!

This silver-white treasure chest can even get level 3 growth liquid?!

！！！！

He quickly took out the bottle of level 3 growth liquid in the bag, the bottle was slightly larger than the level 2 bottle, and the liquid in it was slightly more, red, and it didn't look like anything special.

Wan Lin unplugged the level 3 growth liquid, allowing the energy inside to slowly float out of the bottle and merge into the small sun above his head.

Then he immediately checked his growth value.

Sure enough, 100 points! 1 bottle of Level 3 Growth Liquid can increase your Growth by 100 points!

In this way, his little sun growth value has reached 1839!

There are only 161 years left until the year 2000 of Level 2, and when he goes out this time, the growth liquid in the workshop will definitely be enough for him to upgrade.

The level 1 growth fluid is accelerated by 1 year, the level 2 growth fluid is accelerated by 10 years, and the level 3 growth fluid is accelerated by 100 years, so is it possible that there will be 4 and 5 levels in the future?

Wan Lin Mei thought to herself, is the upgrade getting faster and faster?

He put the bottle of the Level 3 Growth Liquid back in his bag, and then took out another item from the chest.

"Communication chip, what is this?"

Wan Lin carefully read the annotations.

I don't know if I don't see it, I laugh when I see it!

Wan Lin was still depressed that the information could not be delivered immediately, but now there is a solution. If you really fall asleep, you will come to deliver pillows.

A communication chip is a chip that can be assembled and applied in various mobile phones, computers and smart brains.

As long as this chip is installed, you can network in all corners of the world, whether it is calling or sending messages, all of them!

This chip will pass all the data to the system, which will pass it to the docking chip.

It is not an exaggeration to explain that it has become a communication clone of the system.

Wan Lin looked at the communication chip in his hand happily, he searched in the system mall according to this name, and saw this product, but this product was grayed out and could not be purchased at all.

So he can only use 3 of them in his hand now.

Wan Lin doesn't need it himself, as long as the system docks his own brain, and the rest can be given to 3 people.

As long as each other knows each other's chip number, it is equivalent to a phone number, and they can confirm the identity of the other party and communicate with each other by phone or information at any time.
