The next morning, Lei Na was awakened by a noisy sound of gold and iron. Who disturbed people's dreams so early? She opened her eyes angrily and suddenly found that there was no one in the capsule tent. Where were Brother Xi and Sister Ying'er?

?

She hurriedly ran out of the tent and ran towards the source of the noise. What was this? Radium's eyes were attracted by a huge metal sphere. And the two people she was looking for, Di Feng, were tinkering with the big metal ball.

Nana, are you awake? Come and see Brother Xi’s another masterpiece. Feng Ying’er saw Lei Na appearing and greeted her quickly.

After listening to Feng Ying'er's words, Lei Na happily ran to the big metal ball. However, she looked left and right, but she still couldn't see anything. Brother Xi, what is this big ball for? If you don't know how, we can just sit on it and sneak in.

Under the sea.

Nana, I didn’t expect you to be right this time. Di Xi said with a smile.

Ah! Lei Na was surprised. She just said it casually, but she didn't expect that this big ball was really used for diving.

Yesterday, Brother Xi and I accidentally searched for historical invention information and stumbled upon the structural diagram of a submarine. Feng Ying'er said.

This submarine was probably invented hundreds of years ago. Although it has been eliminated, in the current environment, using a submarine is a good way. Of course, it is also a diving tool that we can make using current materials.

.Di Xi added.

It looks very powerful. How did you make this thing? Lei Na asked.

With the design drawings, everything becomes very simple. Di Xi explained that in ancient times, if people wanted to build a submarine, it would be impossible in just a few months. But we have this magical power of interest gold.

Material. We only need to use mental power to control the form of interest gold according to the design drawing, and all the assembly parts can be produced in a short time.

Moreover, Brother Xi has simplified the original drawing of the submarine a lot. Now this simple diving ball is enough to accommodate the three of us. Feng Yinger said,

The completion of the diving ball was also thanks to Ying'er's help. The final assembly was all controlled by Ying'er's mental power. Di Xi also quickly praised Ying'er.

It’s nothing. Brother Xi is busy, how can Ying’er not help? Feng Ying’er said modestly.

So how do you sit in this? Lei Na asked.

This is simple. Di Xi said, and as soon as he concentrated, the Mengyuan Badge immediately issued an order to the diving ball. The top of the big ball roared, and the hatch opened.

It's quite impressive! Lei Na immediately became interested, and before Di Xi could say anything, she quickly ran into the diving ball.

Brother Xi, let’s follow too! Feng Ying’er looked at Lei Na’s back and said helplessly.

That's fine. If you don't go, God knows what kind of trouble Xiao Longnu can do. Di Xi had no choice but to pull Feng Ying'er and jump into the diving ball together.

There are so many buttons inside, what are they for? Before the two of them entered the door, they heard Lei Na muttering inside. The two of them were startled and jumped in quickly.

Fortunately, Di Xi reacted in time and grabbed Lei Na's hand decisively when she was about to press the buttons randomly. Nana, don't move.

Almost! Feng Ying'er also breathed a sigh of relief. Nana, don't press it randomly, or you may break the diving ball accidentally.

You know, I just need to stay away from here! Lei Na was obviously not convinced and kept stepping back without paying any attention to the operating lever behind her.

Lei Na doesn't want it! Di Xi exclaimed, but it was too late.

Ah! Lei Na yelled, and her whole body hit the operating lever. There was only a loud noise, and the diving ball started. The huge ball was like this

What should we do? Lei Na knew that she was in trouble, and her expression suddenly changed.

It's okay, Ying'er, look at Nana! As Di Xi said, he reached the driver's seat in a flash. He quickly pressed several buttons and finally stabilized the bumpy diving ball. However, the diving ball did not

Stopped and still rolled straight towards the sea.

It seems we can't stop. Forget it, let's just start the mission. Di Xi said helplessly.

What should I do? I didn’t expect that Lei Na’s face changed drastically in an instant, and she looked like she was hopeless. I haven’t eaten breakfast yet!

I'm still thinking about eating it! Feng Ying'er looked like he was hating the iron, so it's good that he didn't get into any big trouble.

Ying'er, forget it, this seems to be a kind of guidance. Anyway, the equipment is in my dimensional bag, so it won't be a problem. Di Xi quickly came over to smooth things over. Feng Ying'er calmed down a lot.

Then I'm still hungry! Lei Na still said unwillingly.

Take it and eat it! Di Xi had no choice but to take out a spare stomach pill from the dimensional bag and handed it to Lei Na. But Nana, after a while, I may need to rely on your strength.

That's no problem. I'm full and I have plenty of strength. Lei Na swallowed the pill and immediately said with a smile on her face.

Nana, the mission is important, you must obey the command next time. Feng Ying'er was afraid that Lei Na would cause some trouble again, so she quickly warned.

Got it! Lei Na made a face towards Feng Ying'er and said, Sister Ying'er, I think you are becoming more and more like my mother.

How to say this?

It’s too lenient. Lei Na muttered in a low voice.

You little girl! Feng Ying'er's force field barrier opened instantly, shutting Lei Na inside.

Sister Ying'er, I was wrong. I was wrong. Isn't that okay? Lei Na saw that the situation was not good and immediately begged for mercy.

But Feng Ying'er ignored him and sat down next to Di Xi. Seeing this, Di Xi secretly gave Feng Ying'er a thumbs up, Ying'er, you still have a way. In the future, you will be a mother and educate your children.

There must be a set.

Brother Xi, look at what you said. The thin-skinned Feng Ying'er blushed without any suspense.

Plop! At the same time, the diving ball finally fell into the sea, but soon it floated on the surface again.

Okay Nana, if you don't move, I'll ask Ying'er to let you out. Di Xi still feels sympathy for Lei Na.

Brother Xi, I promise you, sit next to me obediently. Lei Na immediately pretended to be pitiful.

Yinger, do you see it?

Okay, but if you are naughty again, you will still be locked up. Feng Yinger waved his hand, and the force field barrier disappeared immediately.

Lei Na quickly got in between the two of them like a loach, and said flatteringly: You two are the best. Brother Xi, come and show us how to operate this big ball.

Okay, look, this button is the start button. As he said that, Di Xi pressed the red button. Two propellers immediately stretched out from under the diving ball and moved forward at full speed! Di Xi gave the order, and the propellers immediately started to rotate rapidly, and the diving ball

Rolling up a wave of waves, moving quickly towards the destination.

Then how does it dive? Lei Na asked again.

It was this button. Di Xi pressed the blue button on the left again. A hole was opened on the side of the diving ball, and the huge suction force directly sucked the seawater in. As the seawater continued to be sucked in, the diving ball gradually began to sink.

There is a vacuum between the cockpit where we are and the outer wall. As the diving ball sucks in seawater, the entire mass increases, and the diving ball will naturally sink. After we complete the task and drain out all the seawater, we will

It can float. Before Lei Na could ask any questions, Di Xi briefly explained the principles of the diving ball to her.

Now it seems that this big ball is not as magical as imagined. After knowing the secret, Lei Na was obviously a little disappointed.

Brother Xi, it seems you can stop drinking water first. Feng Ying'er reminded.

That's right, thank you Ying'er. Di Xi quickly closed the water inlet, and the diving ball stopped descending and floated in the middle of the sea.

Nana, let me show you something fun. Di Xi said and pressed the green button again. A slender black cylinder immediately popped out from the top of the cab.

What is the use of the glass above? Curious baby, Lei Na hurriedly went up to it.

See for yourself, Feng Ying'er said.

After receiving Feng Ying'er's approval, Lei Na felt like she was being pardoned and immediately raised her eyes. Is this? The scenery on the sea! Lei Na said in surprise.

This is actually a periscope made by applying the principle of refraction of light. It must be said that people in ancient times really had extraordinary wisdom. Di Xi said with infinite emotion.

That's right, our current detection tools are either normal particles or mental search. But I didn't expect that this primitive tool could be so wonderful. Feng Ying'er also agreed.

Brother Xi, do you want to give this big ball a name? Lei Na suggested.

Is that a good idea? Do you have any good names? Di Xi asked.

Now, how about calling it Nautilus? Feng Yinger suggested.

We are afraid that Verne will sue us for copyright infringement. Di Xi replied.

That's called the Golden Meili! Radium suggested.

This right seems to be infringed even more.

Then Brother Xi, you should do it yourself. Lei Na said impatiently.

Let's just call it "Liu Zhu Hao". Di Xi couldn't choose a name casually.

It's quite famous. Lei Na didn't object to the name.

Brother Xi, I have another question. Feng Yinger suddenly asked.

Ying'er, please tell me.

Who is that Verne? Feng Yinger asked curiously.

This, this is not important. Di Xi said blankly.

Okay, Nana crew. Lower the periscope and we are going to dive into the deep sea. Di Xi ordered in a serious tone.

Yes, Captain! Radium quickly got into character and immediately put away the periscope.

The Liuzhu began to absorb water again and sank at full speed. Di Xi pressed the yellow button, and the ball wall in front of them immediately opened, and a transparent observation window appeared in front of them. The scenery of the seabed was immediately unobstructed.

It turns out that this is what the bottom of the ocean looks like! Including Lei Na, the three people in the Liuzhu have never seen what the bottom of the ocean looks like.

Yes, no matter how rough the sea is, it is so calm below the sea. Feng Ying'er couldn't help but sigh.

It’s just that there seems to be nothing in the sea! Lei Na said with some disappointment.

There is nothing we can do about it. After all, this is just a saltwater lake. In fact, the impact of radiation is still very serious, and it is not surprising that there are no marine life. Di Xi explained.

Okay, after passing through the long and narrow waterway ahead, we will enter the real sea. Di Xi pointed ahead and said.

I hope there are still signs of life there. Feng Yinger prayed secretly.

Everyone, hurry up, I have to speed up. After saying that, Di Xi pressed the acceleration button. Several propellers protruded from under the diving ball, and the speed doubled in an instant.

As soon as the Liuzhu entered the waterway, a strong air flow hit him, causing the diving ball to jolt. Be careful of the current, Ying'er is relying on you! Di Xi said to Feng Ying'er while controlling the Liuzhu.

.

Received! Feng Ying'er didn't dare to neglect, and immediately opened a barrier outside the sphere, trying his best to resist the invasion of the sea current.

Ying'er, hold on, we're about to rush over!

Brother Xi and Sister Ying'er, hold on, come on. Lei Na was also extremely anxious on the side, but unfortunately she couldn't help, so she could only keep cheering for the two of them.
Chapter completed!
