Chapter 10 Hidden Treasure in the Sea
It is hard to imagine that such a small propeller can produce such a strong thrust.

'Benben' now weighs 60kg, and the thrust generated by the propeller can make 'Benben' leave the ground, which means that the thrust can reach at least 600N.

And this thruster is a pure electric system!
Thinking about it, Cai Jin was extremely excited.

After fully charging 'Benben', Cai Jin couldn't wait to take it to the beach.

Arriving at the beach, 'Benben' automatically switches the walking environment to 'beach' mode, walking very vigorously.

Get into the water quickly.

Cai Jin looked at the operation panel and operated the thrusters for testing.

In the surrounding sea area, within 1 kilometer, the depth of sea water is nothing more than 10 meters.

At this time, there is not much wind and waves.

The power of the propeller was fully turned on, and soon he tested that the maximum speed of 'Benben' underwater reached 10m/s, and the maximum thrust of the propeller was 6000N.

In the underwater environment of seawater, everything appears on the operation panel, the depth of seawater is not too deep, and the light is still sufficient.

The bottom of the sea here is all white and fine sand. Occasionally, sea fish and shrimps will happily drill into the sand. When they come out, they will bring up some algae deposits and swallow them with their mouths open.

This made Cai Jin very curious. As a person who grew up by the sea, he is actually full of yearning for the sea.

The sea is vast and mysterious, and of course it is also dangerous.

They have been told since childhood that they can play in the sea, but not too deep.

"This is a yellow-finned fish?" Cai Jin saw a yellow-finned fish about the size of a palm appearing in his sight, and the yellow-finned fish was swimming freely.

Cai Jin issued an order, and the mechanical arm of 'Benben' stretched out, and quickly and accurately clamped the 'Yellow Fin Fish'.

Then under Cai Jin's control, he quickly returned to the beach, and then released the mechanical arm in front of Cai Jin.

Cai Jin is happy.

If you want seafood, you need to go fishing hard, just let 'Benben' go down and catch it.

Cai Jin had a great time.

When Benben was about to run out of electricity, the temporary puddle that Cai Jin made was full of seafood such as yellow-finned fish, conch, octopus, blue and white crab, and sea bass.

Manipulate 'Benben' to transfer these sea goods from the puddle to the bag.

Satisfied, Cai Jin took 'Benben' away.

For dinner, a delicious seafood dinner.

It is said that delicious ingredients often only need simple cooking, which is true.

There are not too many bells and whistles. The yellow-finned fish is directly boiled in soup with a few slices of ginger. Other seafood such as conch, octopus, blue and white crab, and sea bass are directly steamed.

The whole family ate to their heart's content.

In the early morning of the next day, Cai Jin came to the beach again with a fully charged 'Benben'. At this time, the sea water was already high tide, and more than half of the beach was submerged.

But this is not a problem at all for 'Benben'.

The body of 'Benben' was soon submerged in the sea water. When it entered three meters of sea water, Cai Jin manipulated 'Benben' to turn on the propeller.

Otherwise, at the bottom of the sea, the walking speed of 'Benben' is very slow.

With thrusters, 'Ben Ben' is quite fast.

In the sea, a fully charged 'Benben' has a battery life of only four hours, which means it can travel for an hour and a half.

And at its fastest speed, one and a half hours is enough to travel 54 kilometers!

And you must know that the width of the strait here is only 240 kilometers.

Within this 54-kilometer range, the depth of sea water is nothing more than 50 meters.

"The bottom of the sea is really beautiful!" Cai Jin looked at the screen, colorful fish, and sea shrimps and crabs that he had never seen before!
Suddenly, Cai Jin saw a big hole in a big rock not far ahead from the screen.

"I don't know if there are gentian or eastern star spots in this big hole!" Cai Jin was curious.

Manipulating Benben to go to the big hole, the big hole is pitch black.

Turning on the lights, Cai Jin suddenly saw a big box in the big hole.

The box is in the shape of a cube, about one and a half meters in length, width, and height. The box looks simple and simple, and it is firmly imprisoned by iron chains. It is easy to remind people of the legendary treasure chest.

"I don't know who put this box. It looks like the iron chains are rusty, at least it's been there for decades." Cai Jin speculated secretly.

The 'Benben' mechanical arm easily tore off the iron chain, then bit one of the corners, and pushed towards Cai Jin.

In order to speed up, Cai Jin made 'Benben' float to the surface of the sea with the big box, and then pushed forward quickly.

It didn't take long for the box to arrive.

Cai Jin didn't open the box here, but put the box on 'Benben' and went home directly.

Back home, Cai Jin found a hammer and threw it at the rusty lock.

He smashed it with a bang.

After the box was smashed open, Cai Jin's eyes lit up.

The inside was actually made of very good sealing material, and no sea water got in.

On the top of the box, there are rolls of paintings sealed in sealed bags, and there are three paintings in full.

Taking out the three paintings, Cai Jin did not rush to open the sealed bag.

Because at this moment, he was dazzled by the things underneath.

The small yellow croakers were neatly arranged, glittering with gold, and the impact was unbearable for Cai Jin, who is a multi-millionaire.

After all, the money in the account is just a bunch of numbers.

But these golds are real.

It took a long time for Cai Jin to react.

The small yellow croakers were taken out one by one, and a total of 200 small yellow croakers were taken out.

This is more than that, because under the small yellow croakers are big yellow croakers.

There are a total of 100 of these large yellow croakers!
A small yellow croaker weighs 31.25 grams, and a large yellow croaker weighs 312.5 grams, which means that the gold in this box weighs 37500 grams, or 37.5 kilograms!

The price of gold has risen sharply this year, from 369 yuan/gram a year ago to 500 yuan/gram, which means that the gold is worth 1875 million yuan!

With this gold and the 1000 million yuan just entered into the account, it means that the money for the factory renovation he wants to carry out is almost enough.

Taking a deep breath, Cai Jin took a few deep breaths to calm himself down.

Afterwards, Cai Jin immediately put the gold back into the box, and then carried the box up to the third floor.

At this time, he was quite lucky, fortunate that there was no one at home, otherwise it would be troublesome if there were too many people talking.

After reaching the third floor, Cai Jin opened the sealed bag.

Because of the good sealing, these paintings are well preserved.

He opened a painting and looked at it.

The characters in the painting are lifelike.

A person dressed as an official is sitting under a tree, looking at something seriously.

On the opposite side of the official, a lady is playing the piano.

Behind the lady is a screen with beautiful mountains and rivers painted on it.

It turned out that the official was listening to a lady playing the piano in a courtyard.

Although the whole painting is simple, it has a lofty artistic conception, which makes people have an immersive feeling when they look at it.

Even if Cai Jin doesn't know calligraphy and painting, he can still know that this is a good painting.

And when he saw the author, Cai Jin was stunned.

Then I was very excited.

The author of this painting is none other than Tang Yin Tang Bohu, who was known as the "Merry Talent" in the Ming Dynasty.

Cai Jin's impression of Tang Bohu comes from two films and TV shows, one is the movie "Tang Bohu Spots Autumn Fragrance" by Master Xing, and the other is the TV series "Four Geniuses in Gold Suits" starring Zhang Jiahui.
