National Island: I Build a Home on the Back of a Giant Turtle

　　 The weight and buoyancy of the submarine have been calculated. When Chu Chen and four mermaids are inside, the submarine will float because the buoyancy is greater than gravity.

　　 The way to make it sink is very simple. Chu Chen threw a large pile of seabed gold directly from the storage space, increasing the weight, and it would sink.

　　 Two tufts of gold under the sea were prepared in his storage space. The largest tuft can make the submarine sink quickly. At this time, the buoyancy is less than gravity!

　　 The middle tuft allows the submarine to hover in the sea. At this time, the buoyancy is equal to gravity.

　　 Put all these seabed gold into the storage space, the buoyancy is naturally greater than gravity again, and the submarine will float.

　　.

　　 What an easy way!

　　 As for power, let the mermaid patriarch use the water control ability, and Chu Chen will also use this ability.

　　 That’s why it is made so fast!

　　 After the manufacturing is completed, the pressure of hundreds of thousands of meters under the sea has been simulated through special instruments. This submarine has no problem withstanding it.

　　.......................................

　　 After the submarine was manufactured, Chu Chen directly loaded this small submarine into the storage space that had been expanded to 6,400 cubic meters, and then came to Turtle Island No. 3, which was already in the center of the sea.

　　 The mermaids are already here.

　　 "Let's go~"

　　 Chu Chen took out the submarine and got in first.

　　 Caiwei, Shanshan, Tina, and the mermaid patriarch all got into the submarine.

　　 One Chu Chen, three mermaids, and one little snake girl.

　　 Under such a weight, the buoyancy of the submarine is still greater than gravity, and it did not sink.

　　Chu Chen threw out the two lumps of sea gold directly.

　　 Then the submarine began to sink quickly.

　　 It's just that, the lower you go, the slower the sinking speed.

　　 Because the sea water is denser.

　　 Chu Chen estimated that for a distance of hundreds of thousands of meters, I am afraid that it would take a long time to dive.

　　 As expected.

　　 After a long time, Chu Chen knew through the instrument that they had finally dived to a distance of 100,000 meters under the sea.

　　 Along the way, I have encountered ancient species a few times, but because they didn't have any sound or light inside, the ancient species seemed not interested in the iron bumps made of gold under the sea.

　　 The submarine continued to dive.

　　 After a few more hours, finally, it reached the position of the lunar core! .

Chapter 150:

　　 "It's coming soon, Brother Chu Chen."

　　 In the submarine, the voice of plucking flowers sounded.

　　 Chu Chen let out a "um", and took away the largest seabed gold in the submarine through the storage space. Then, the sinking momentum of the submarine slowed down and hovered in the air.

　　 When Tang Lei was calculating, she had already calculated that the density of the sea water was more than 100,000 meters deep, and the density of the sea water was different from the above factors.

　　.

　　 After the submarine hovered, Chu Chen clicked a few switches, and then bright lights came on around the submarine.

　　 These lights are naturally made of transparent seabed gold and white crystals.

　　 Otherwise, how could it be possible to withstand such water pressure.

　　.

　　 In deep water, such a strong light can still shine hundreds of meters away.

　　 The holographic screen of the Chuchen Island Master's watch has already appeared in a large number of pictures. This is the picture taken by the high-definition camera arranged around, which is clearer than the naked eye and can see the surroundings.

　　 Now, the distance between the submarine and the lunar core is still more than 100 meters away.

　　 The lunar nucleus with a diameter of ten kilometers is still very large, and only some changes in the curvature can be seen, and it is impossible to see the entire lunar nucleus completely.

　　 The surface of the lunar core was quite smooth. It seemed that after the impact, all the attachments on the surface of the lunar core were knocked off.

　　.

　　 "Irina, leave it to you."

"Um!"

　　 Irina, the mermaid patriarch, activated the water control ability, and controlled the water flow behind the submarine to drive the submarine to move.

　　 The speed is not slow.

　　 The submarine passed along the surface of the lunar core, and Chu Chen also took a close look at the lunar core.

　　 In this way, after more than an hour, the submarine finally passed the lunar core and entered the periphery of the lunar core.

　　 After the submarine fell to the bottom of the sea, Chu Chen discovered that there was indeed a lot of gold on the bottom of the sea around the lunar core.

　　 and they are all unusually large.

　　 "Irina, go over there~"

　　 Chu Chen asked Irina to use the water control ability to push the submarine to a piece of gold under the sea.

　　 Then, Chu Chen's mental power reached out.

Submarine gold has a very strong blocking effect on mental power. Fortunately, when making the submarine, Tang Lei engraved some supernatural power patterns inside a piece of submarine gold in front, so that Chu Chen's spiritual power can at least be detected. Ten meters away.

This is enough.

　　 Soon, Chu Chen's mental power "touched" the piece of seabed gold, and then Chu Chen thought about it, and the piece of seabed gold appeared in the storage space.

　　 This is a piece of undersea gold with a length of more than 10 meters!

　　 Such undersea gold, in the past, I didn't even dare to think about it.

　　.

　　 After having successful experience, Chu Chen continued to let Irina control the submarine to move. This time, he picked a large piece of seabed gold.

　　 Of course, it’s too big to fit in.

　　 The size of the storage space now is 6,400 cubic meters. Don't think it is too large, it is equivalent to a long, wide, and high cube.

　　 But don’t think it’s too small, because the storage space is not a cube, and stuff inside is not piled up like ordinary stuff.

　　The things put in are all independent, as long as the total volume of these things exceeds 6,400 cubic meters.

　　 Under the sea gold with a length of more than 10 meters like this, you can still put dozens of pieces.

　　.

　　 Even so, because the surrounding seabed gold is too much.

　　 It only took less than an hour, and all the gold under the sea was loaded into the storage space.

　　 Then, Chu Chen let the submarine float up, put all the seabed gold back into the warehouse on Turtle Island, and then turned back to continue the process.

　　......................................

　　 The second time I dived Chu Chen and let Irina directly use her ability to accelerate, it was much faster.

　　 In this way, once and again, the final time is about 3 hours.

　　 Then.

　　 Chu Chen collected seabed gold back and forth in this sea area at a frequency of four to five times a day.

　　 With this collection, Chu Chen collected it for half a month.

　　 Although it took half a month, Chu Chen's gain was huge.

　　 In the warehouse on Turtle Island No. 1, gold under the sea has been piled up into mountains!

　　 So many sea golds shocked Tang Lei!

　　.

　　 It can be said that the seabed gold collected in the past half month can be used for Tang Lei to do too much.

　　 Whale battleship can build many ships, these seabed gold can also be used to build the armor of ordinary battleships.

　　 As for the submarine gold needed for the mermaids' equipment, there is no need to look for them everywhere.

　　 "You can take a break first."

　　 After working on this matter for half a month, Chu Chen was also a little tired. Fortunately, every night, the little mermaid Caiwei and the little snake girl Tina would press their heads to relieve him.

　　.

　　 These seabed gold are enough for a long time.

　　 When it runs out in the future, the mermaids have also evolved. Then, without Chu Chen's hands, the mermaids can collect these seabed gold.

　　 "Collect again!"

　　 Seeing that it wasn't until the afternoon today, Chu Chen decided to collect sea gold again, and would not do this again tomorrow.

　　 Soon, he dived underwater again, and quickly filled the storage space.

　　 "Go back~"

　　 Chu Chen put all the gold under the sea into the storage space, and the submarine began to float.

　　 "Brother Chu Chen, wait a minute~"

　　 At this time, the voice of the little mermaid plucking us rang out.

　　 "What's wrong, Plucking?"

　　 Chu Chen asked.

　　 "Brother Chu Chen, look at ｀｀~"

　　 Caiwei pointed to the lunar core captured by a high-definition camera on the holographic screen, said.

　　 Chu Chen glanced at it, and suddenly his gaze paused.

Because.

　　 There are some symbols on the top of the moon core!

　　 These symbols are like those carved on the moon core!

　　.........................................

"what is this?"

　　 Chu Chen whispered.

　　 "Go, go over and take a look."

　　 The submarine headed towards the lunar core and soon arrived nearby. Now, I can see more clearly.

　　 There are indeed symbols on the lunar core, which is all composed of seabed gold. There are not only one of these symbols, but many.

　　The submarine moves along these symbols.

　　 Chu Chen discovered that these symbols, covering a large area, formed a huge figure.

　　 Then, in the middle of these figures, he found a door pattern.

"door?"

　　 The submarine flew to the neighborhood. That door, which looked like a pattern, didn't seem to be a real door.

　　 The door is very big, if it is a real door, the submarine can get in.

　　.

　　 Around the door, there are also a lot of patterns, which seem to be some exquisite pattern decorations.
