The construction of a large number of submarine cities requires a large amount of oxygen, which is different from the ground.

There is almost no breathing oxygen in the ocean, so a lot of marine plants are needed to produce oxygen!

Walking into the experimental greenhouse, I saw a lot of seaweed immersed in seawater, and the breeder was testing its cold resistance and oxygen production.

Ying Ziyue said: "In the ocean, the most indispensable resource is sea water, so we have to find a way to convert sea water into usable resources."

Nowadays, the technology of artificial sun has become more and more adept. In the experimental greenhouse, the artificial sun hangs high in the sky.

The seagrass irradiated by the sun begins to photosynthesize and produce a large amount of oxygen.

These seaweeds have been genetically modified for generations to maximize the oxygen production of photosynthesis.

The oxygen required for respiration has also been reduced to a minimum!

As long as the two experimental greenhouses alternate photosynthesis, then this submarine city can continuously produce oxygen!

At this time, Ying Ziyue turned on the test instrument, and the oxygen content in the air had reached 30%!

Oxygen diffuses in the submarine city, and it may be diluted, but the oxygen content in it is close to the ground level, which is terrible!

Not only that, Ying Ziyue took Yu Xiu to the outskirts of Atlantis, and he was immediately shocked by the scenery in front of him!(Read more @ mtlarchive.com)

Colorful corals occupy his vision, and each coral is tens of meters tall!

This is no longer ordinary coral, but a colorful coral forest.

These coral forests are on the bottom of the sea, without any light, they actually produce a lot of oxygen!

This coral forest is also the latest research result of the Atlantis Institute of Marine Botany.

By changing the plant genes of corals, these corals can finally produce oxygen at the bottom of the sea, just like forests.

It's just that the life span of corals is greatly reduced. In order to make up for the lifespan defects, the researchers have maximized their reproductive capacity!

As the saying goes, wildfires are endless, and spring breeze blows again!

The oxygen produced by coral forests can not only be used as oxygen supply for submarine cities, the excess oxygen rising to the sea surface can also increase the oxygen content in the atmosphere!

Yu Xiu couldn't help but look at Ying Ziyue. When he built this submarine city, he really took all aspects into consideration..

Today's Atlantis is an unbreakable fortress!

For a civilian submarine city, the problem of oxygen must be solved first, followed by the problems of light and food.

In the experimental greenhouse, land plants that can be irrigated with seawater have begun to grow.

First, there are two kinds of plants, potatoes and sweet potatoes. These two plants have short growth cycles, high yields, and strong adaptability. They are definitely the best choice for solving food problems!

At night, after Yu Xiu returned to his room, he began to sketch and paint the underwater city.

Visiting Atlantis today made him fully understand that this is a magical era, and this is an unprecedented era for human civilization!

Ying Ziyue is also very much looking forward to his results. Once successful, civilian submarine cities will spread across the entire eastern country on a large scale!

When ocean cities began to spread the seabed, it was the second step of Poseidon's plan.

For the advancement of human civilization and for the disasters to be dealt with next, Poseidon plans to speed up its pace! .
