The Tokai Trough is a lithospheric extension of the Ryukyu Trench, with a total length of about 840 kilometers and nearly 100 kilometers at its widest point, with a total area of more than 246,000 square kilometers.

The average depth here is more than 1,000 meters, and the water depth where Lu Zheng dived and landed along the edge of the continental shelf in the East China Sea was about 1,200 meters, far from reaching the deepest place.

The trough has a variety of landforms such as mountains, hills, ridges, trenches, basins, and plains. The terrain near the trough slope on the east side is complex, with mountains, dense ravines and undercurrents, which is not suitable for long-term development.

The most important thing is that Lu Zheng's current Dragon Palace belongs to the level of Hebo Water Mansion, which has the front hall, the back hall, the middle hall, as well as the Dragon Pond and the Living Water Vortex Pond, which are placed in the river, and the scale is incomparably grand.

But in the extremely vast trough, the poor one is similar to a roadside thatched house.

This is definitely not the East China Sea Dragon Palace that Lu Zheng wants.

Therefore, his plan is by no means as simple as simply manifesting the Dragon Palace. He wanted to find a flat and vast plain, set up Hebo Water Mansion as the center of the Dragon Palace, and then transform the surrounding environment to restore the legendary coral, swimming fish and frolicking, gorgeous and bright East China Sea Dragon Palace.

Of course, this is only an idea at the moment, and where to start is still up for debate.

After activating the Water Dragon Diagram, no matter how Lu Zheng poured the Heavenly Water True Night, the Hebo Water Mansion showed no sign of advancing towards the Sea Dragon Palace, and it seemed that it had encountered a bottleneck.

Lu Zheng only vaguely felt that the Dragon Palace he inherited should be missing something important, not a complete Dragon Palace.

As we continue to explore eastward, the slope begins to slow down as the water depth increases, and the seamounts, ridges, and trenches become more and more thin.

After about 20 kilometers, the slope was completely flattened, and Lu Zheng gradually explored in all directions, and preliminarily determined that he had entered a submarine plain, with an area of at least 600 square kilometers, both in terms of terrain and depth. It is basically in line with expectations.

However, there seems to be a dilemma that needs to be solved urgently.

The oceans have been on Earth for 4 billion years, and during this long time, things that have been brought into the ocean by terrestrial rivers and the atmosphere and that have fallen into the ocean floor by human activity. Including soft mud, dust, animal and plant remains, volcanic materials, etc., and even the carapace wreckage of a shipwreck, the number is simply incalculable.

The seabed was so soft that Lu Zheng's dragon claws could penetrate the sediment several meters deep with a little force. Soft mess. And a few meters deep is only the epidermis of sediment, that is, the excavator team that hired Lan Xiang to graduate, if you want to completely remove it, it will take at least tens of thousands of years.

It's so desolate, desolate that it makes my heart palpitate.

The Dragon Palace is magnificent and gorgeous, and the environment around the Dragon Palace must also be magnificent and gorgeous.

This vast and desolate submarine plain needs embellishment, a lot of embellishment. And the most adorning thing in the sea is coral.

There are many kinds of coral images. Tree branches, grass, beehives, lilies, sponges, etc., are bright and beautiful, and the coral bushes that are both beautiful and strange are connected together, which can be called a wonder in the sea.

Pink, red, purple, blue, white, and black are intertwined with each other, like pairs of gorgeous antlers, flowers, jade trees, clusters of trees. It's like a mesmerizing colored forest.

And the role of corals is much more than just decoration, large coral reefs can affect the physical and ecological conditions around them, providing the best living environment for life.

Australia's Great Barrier Reef is the largest and longest coral reef in the world. Fascinating, unpredictable and complex currents are home to more than 400 different types of coral reefs, 1,500 species of fish, more than 4,000 species of molluscs, and even habitats for some endangered animal species such as dugongs and giant green turtles.

A variety of gorgeous swimming fish. Colourful polymorphic corals are abundant, and it is the place where marine life is most abundant.

Coral is not actually a plant, but a marine cylindrical coelenterate.

It is precisely because it is an animal that Lu Zheng has the confidence to ignite the polyps to adapt to the deep-sea environment, turning this submarine plain into a magnificent and gorgeous coral seabed.

Imagine huge reefs, corals in all shapes and colors, and sea anemone sponge needles at hand. The color ranges from white, blue to indigo, brilliant and colorful, and corals also have pale pink, deep rose red, bright yellow, blue green, everything is very vivid, and the sea water is dyed with color.

A wide variety of colorful and varied reef fish swim by in schools. Slender moray eels and sea snakes hide in the corals, revealing their sneaky heads.

Then a group of clownfish, blue kingfish, manta rays, hairtails, bigeye octopus, and plaice shuttle through the ocean, with turtles and humpback whales, completely forming the entire real fish lineup of "Finding Nemo"!

Shrimp soldiers and crabs will cruise in clusters of coral bushes, and in the distance there is a bright and bright glass palace.

This is the grand atmosphere that Lu Zheng imagined the Middle East Sea Dragon Palace should have.

Now, his goal is to create a coral seabed of hundreds of square kilometers to consolidate the sediment that covers the seabed and sweep away all the desolation and gloom here.

The more he thought about it, the more eager he became, and Lu Zheng couldn't wait to rush to Australia immediately and move the entire Great Barrier Reef over.

Of course, it's just a matter of thinking about it, the Great Barrier Reef is Australia's proud landscape, Lu Zheng is a dragon king, not a thief, and he has the confidence to build a bigger coral reef with his own hands, surpassing the existence of the Great Barrier Reef.

Thinking of Australia, Lu Zheng suddenly remembered Orinoah, the Australian girl he met on a cruise ship. Her Jack would never have appeared, and she had clearly been fascinated by Jack, wondering if she was still immersed in grief after all this time.

A journey of a thousand miles begins with a single step, and the construction of a coral seabed is not an overnight success.

Write down the location of the plain and swim into the distance again. Constantly cruising and exploring, Lu Zheng is completely immersed in the thrill of this freedom.

Soon, he discovered a strange sight under the sea again.

Sea Springs!

In the middle of an undersea basin, hundreds of gushing springs are densely packed. What shocked Lu Zheng the most was that what was spewing out of the spring was not seawater, but very pure fresh water.

The spring gushes in the middle of the basin and flows far beyond the land spring, so much so that it forms a meandering and turbulent river of freshwater at the bottom of the sea.

The bitter sea water is gone, but very sweet and delicious fresh water.

This means that Lu Zheng can build an underground city here, an undersea city that can be inhabited by humans, without him having to purify the seawater to survive.

This is definitely exciting news. (To be continued.) )
