The next morning, Lena was woken up by the cacophony of gold and iron. "Who is so early in the morning, disturbing people's dreams!" She opened her eyes angrily and suddenly found that the capsule tent was empty. "What about Brother Xi and Sister Ying'er?"

She hurriedly ran out of the tent and towards the source of the noise. "What is this?" Radia's gaze was drawn to a large metal sphere. And the two Di Feng she was looking for were tinkering with this big metal ball on the side.

"Nana, are you awake? Come and take a look at another masterpiece of Brother Xi. Feng Ying'er saw that Rana appeared, and hurriedly greeted.

Listening to Kaede Shadow's words, Lena ran to the metal ball with great interest. But she looked left and right, and still didn't see any doorway. "Brother Xi, what is this big ball for, won't we sit on it and dive to the bottom of the sea."

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

"Ahh Rana was taken aback, she just said casually, she didn't expect that this big ball was really used for diving.

"Yesterday, Brother Xi and I accidentally rummaged through historical invention materials and accidentally found a structural diagram of a submarine." Feng Ying'er said.

"This submarine was invented hundreds of years ago, although it has been obsolete. But in today's environment, using a submarine is a good idea. Of course, it is also the diving tool that we can make with the current materials. Di Xi added.

"It looks amazing, how did you make this thing?" Rana asked.

"With the design drawings, it's so much easier." Di Xi explained, "In ancient times, if people wanted to build submarines, it was impossible to build them in a few months. But we have the magic of interest. We only need to use our mental power to manipulate the form of the breath according to the design drawings, and we will be able to conjure up all the assembly parts in a short time. ”

"And Brother Xi has simplified the original drawings of the submarine a lot. Now this improvised diving ball is big enough for the three of us to sit. Feng Ying'er said,

"The completion of the diving ball is also thanks to the help of Shadow. The final assembly is all controlled by the mental power of the shadow. Di Xi also hurriedly praised the shadow.

"It's nothing, Brother Xi's help, how can Ying'er not help?" Feng Ying'er said modestly.

"And how do you sit in this?" Rana asked.

"It's easy." Di Xi said, and as soon as he concentrated, the Dream Badge immediately issued a command to the diving ball, and the hatch opened with a hula above the big ball.

"It's quite imposing!" Rana was immediately interested, and before Di Xi could speak, she ran into the diving ball with a puff of smoke.

"Brother Xi, let's follow up too!" Feng Ying'er looked at Leina's back and said helplessly.

"Oh well. If you don't go, God knows what kind of moth the little dragon girl can make. Di Xi had no choice but to pull up Feng Ying'er and jump into the diving ball together.

"There are so many buttons in there, what are they for?" Before the two of them could enter the door, they heard Lena muttering to someone inside. The two were startled and hurriedly jumped in.

Fortunately, Di Xi reacted in time, and when Rana was about to press the button, she decisively grabbed her hand. "Nana, don't move."

"Almost!" Maple Shadow also breathed a sigh of relief, "Nana, don't press it randomly, I'm going to break the diving ball if you accidentally break it." ”

"Got it, I'll stay away from here!" Apparently unconvinced, Rana stepped back with all her might, not paying the slightest attention to the lever behind her.

"Don't want Radium!" Di Xi exclaimed, but it was too late.

"Ahh Lana screamed, and her whole body hit the lever. There was only a loud bang, and the diving ball was activated. The huge sphere is like that

"What can I do?" Rana knew that she was in trouble, and her face changed instantly.

"It's okay, Shadow, you look at Nana!" Di Xi said, and his figure flashed directly into the driver's seat. I saw that he quickly pressed several buttons, and finally stabilized the bumpy diving ball. However, the diving ball did not stop, and still rolled straight towards the sea.

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

"What should I do then?" Unexpectedly, Leina's face on the side changed instantly, and she looked loveless, "I haven't eaten breakfast yet!" ”

"Still thinking about eating!" Feng Ying'er hated the appearance of iron not being steel, "It's not bad if you don't get into a big disaster." ”

"Forget it, this seems to be a kind of guidance. Anyway, the equipment is all in my dimensional bag, so it's out of the way. Di Xi hurriedly came over to play a round. Feng Ying'er eased up a lot.

"Then I'm still hungry!" Leina was still unwilling.

"Take it and eat it!" Di Xi couldn't help it, so he took out a spare stomach pill from the dimensional bag and handed it to Radium, "But Nana, after a while, I may need to rely on your strength." ”

"It's no problem, I'm full, I have the strength." Radium swallowed the pill and immediately smiled all over her face.

"Nana, the task is important, and you have to listen to the command next." Feng Ying'er was afraid that Leina would cause some trouble again, so she hurriedly warned.

"Got it!" Radium grimaced at Fengying'er and said, "Sister Ying'er, I think you're becoming more and more like my mother." ”

"What do you mean by that?"

"It's too wide." Lana muttered quietly.

"Okay, you little girl!" The maple shadow force field barrier opened in an instant, and Leina was locked in at once.

"Sister Ying'er, I was wrong, can't I be wrong?" Seeing that the situation was not good, Rana immediately begged for mercy.

But Feng Ying'er ignored it and sat next to Di Xi by herself. Seeing this, Di Xi secretly gave Feng Ying'er a thumbs up, "Ying'er, you still have a way." As a mother in the future, there must be a set of ways to educate children. ”

"Brother Xi, look at what you said." The thin-skinned maple shadow blushed without suspense.

"Plop!" At the same time, the diving ball finally fell into the sea, but soon it was floating again.

"Okay Nana, if you don't move, I'll let Shadow let you out." Di Xi still has compassion for Leina.

"Brother Xi, I promise you, sit next to you obediently." Rana immediately pretended to be pitiful.

"Shadow, look?"

"Okay then, but no matter how naughty you are, you'll still be locked up." With a wave of Feng Ying'er's hand, the force field barrier disappeared immediately.

Rana hurriedly burrowed between the two of them like a loach, and said flatteringly, "You two are the best." Brother Xi, how to operate this big ball, you can show us. ”

"Well, you see. This button is the start key. As he spoke, Di Xi pressed the red button. Two propellers immediately stretched out from under the diving ball, "Full speed ahead!" Di Xi gave the order, and the propeller immediately spun rapidly, and the diving ball rolled up waves and quickly headed towards the destination.

"And how does it dive?" Rana asked again.

"It's this button." Di Xi pressed the blue button on the left again. A punch hole was opened on the side of the diving ball, and the huge suction force sucked the seawater directly into it. As the water continued to be inhaled, the diving ball began to sink gradually.

"There was a vacuum between the cockpit and the outer wall that we were in. As the ball sucks the seawater in, the overall mass increases, and the ball naturally sinks. When we're done, we'll drain all the water out and we'll be able to float. Without waiting for Rana to ask, Di Xi briefly explained the principle of the diving ball to her.

"Now it seems that this big ball is not as amazing as it seems." Knowing the mystery, Radia was visibly disappointed.

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

"That's right, thank you, Shadow." Di Xi hurriedly closed the water intake, and the diving ball stopped descending and suspended in the middle of the sea.

"Nana, I'll show you another one of the fun." Di Xi said, pressing the green button again. A slender, black cylinder immediately popped off the roof of the cab.

"What's the glass on this for here?" Curious about the baby, Rana hurriedly got up.

"See for yourself." Feng Ying'er said.

With Feng Ying'er's approval, Rana immediately raised her eyes as if she had been pardoned. "This is? What a view from the sea! Rana was a little surprised.

"This is actually a periscope made by applying the principle of refraction of light. I have to say that the people of ancient times really possessed extraordinary wisdom. Di Xi said with infinite emotion.

"That's right, now our detection tools are either normal particles or spirit search. But I didn't expect this primitive tool to be so wonderful. Feng Ying'er also agreed.

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

"A good idea? Do you have any good names? Di Xi asked.

"Yes, how about calling it the Nautilus?" Maple Shadow suggested.

"I'm afraid Verne will sue us for infringement." Di Xi replied.

"That's called the Golden Merry!" Rana suggested.

"This right seems to be encroached upon even more."

"Brother Naxi, it's better for you to come by yourself." Rana said impatiently.

"Let's just call it 'Liuzhu'" Di Xi had no choice but to come up with a random name.

"It's a bit famous." Lena didn't object to the name.

"Brother Xi, I still have a question." Feng Ying'er asked suddenly.

"Shadow, please."

"Who is that Verne?" Feng Ying'er asked curiously.

"This, this doesn't matter." Di Xi said blankly.

"Alright, crew Nana. Lower the periscope and we're going to dive into the deep sea. Di Xi ordered in a matter-of-fact manner.

"Yes, Captain!" Leina also quickly entered the role and immediately put away the periscope.

The Liuzhu began to absorb water again, sinking at full speed. Di Xi pressed the yellow button with his hand, and the ball wall in front of them immediately opened, and a transparent observation window appeared in front of their eyes. The view of the bottom of the sea is unobstructed.

"That's what the bottom of the sea looks like!" The three people on the Liuzhu, including Lena, had never seen anything from the bottom of the sea.

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

"It's just that there's nothing in the sea!" Rana said with some disappointment.

"There's no way around that, it's just a saltwater lake after all. In fact, the effects of radiation are still very severe, and it is not surprising that there are no marine life. Di Xi explained.

"Alright, go through that narrow waterway ahead and we'll be in the real sea." Di Xi pointed ahead and said.

"I hope there are still signs of life there." Maple Shadow prayed secretly.

"Everyone, hurry up, I'm going to speed up." After speaking, Di Xi pressed the acceleration button. Several more propellers stretched out from under the diving ball, doubling its speed in an instant.

As soon as the Liuzhu entered the waterway, a powerful air current rushed into its face, causing the diving ball to jolt for a while. "Be careful that it's the current, the shadow is on you!" Di Xi said to Feng Ying'er while controlling the Liuzhu.

"Roger!" Feng Ying'er didn't dare to slack off, and immediately opened a stance barrier outside the sphere, trying her best to resist the invasion of the current.

"Shadow, hold on, we're going to rush over!"

"Brother Xi, Sister Ying'er hold on, come on." Rana was also very anxious on the side, but unfortunately she couldn't help, so she could only keep cheering for the two.

"It's just a little bit there." Di Xi pulled the lever to the end, and the Liuzhu accelerated violently, finally getting rid of the encirclement of the current and rushing into the real sea.
