My Items Can Upgrade-Chapter 462 - 217: Is the World Itself a Marvel?
Inside the ocean, microorganisms began to appear.
At this time, the upgrade finally came to an end.
[World lv.2: 0/2000 (...the small world already has microorganisms; cannot upgrade.)]
The diameter of the secondary small world, as expected, directly doubled, and the planetary diameter became 200 kilometers, with a significant increase in land area.
Yang Yuan looked at the small world along the coast that already showed some green, and with a thought, accelerated the day-night cycle of the small world once again.
During the upgrade process, day and night will also alternate, but no experience will be generated.
Because the day-night cycle during the upgrade process belongs to the upgrade state, which is a feature of the world itself.
Once the day-night cycle stops, this small world may collapse because the essence of this world is the sun and moon, or rather, the power of yin and yang.
Soon, two thousand days passed, and the experience was sufficient again.
However, this time, Yang Yuan did not upgrade directly but continued to gather experience, preparing to accumulate enough in one go to advance to the Marvel level.
After an unknown period, the experience was finally sufficient.
Only then did Yang Yuan begin the upgrade.
He planned to let Zhao Jiayan and others enter the small world once enough experience was gained and set off alone to seek the Game Government’s headquarters, which would be faster.
As before, one second outside is equivalent to a year inside the small world.
Therefore, in the upgrade state, the day-night cycle of the small world is extremely fast, so fast that outsiders cannot see the situation inside the small world clearly.
"Rumble..."
The small world experienced large-scale volcanic eruptions again, which is the method of expansion for the small world. Energy erupts from the depths of the core, increasing the land area through magma and other means.
Water vapor and others also need to be ejected from the underground through volcanic eruptions, spread across the entire surface, and then fall to the ground through rainfall.
During volcanic eruptions, there are flashes of lightning and thunder, as the essence of this world is actually the magnetic field.
Even the sun and moon cannot be separated from the main magnetic field of the small world; it is the magnetic field that binds the sun and the moon to the earth’s core.
Thus, the operation of the sun and moon can truly cause the alternation of day and night and truly change the internal flow of time.
As before, one second outside equals a year inside, and after three minutes outside, 180 years have passed in the small world.
During these 180 years, the changes within the small world were massive.
Firstly, volcanic eruptions brought a large amount of organic matter, allowing the microorganisms on the surface, especially in the ocean, to evolve rapidly.
As a result, algae and other initial plants appeared.
Subsequently, various single-celled organisms were born.
At this point, the small world upgrade concluded, successfully reaching level three, and the diameter of the small world’s planet doubled again to 400 kilometers.
With enough experience, Yang Yuan continued upgrading.
In the blink of an eye, another three minutes passed, and 180 years transpired within the small world again.
During these 180 years, the single-celled organisms in the depths of the ocean began evolving into the earliest fish species.
However, that was all the progress made, as the upgrade ended, and the small world reached level four.
The level four small world could already accommodate organisms, as a large amount of water vapor and various particulates formed the world’s atmosphere.
Then the atmosphere scattered light, creating blue skies and white clouds, no longer the previous pitch-black.
It’s worth noting that during the upgrade from level three to four of the small world, the size didn’t change at all. The real transformation mainly concerned biodiversity, as single-celled organisms evolved into various fish species.
But at this time, the fish species were still small organisms.
Yang Yuan continued upgrading.
To advance from level four to five took five minutes, equivalent to 300 years within the small world.
During these 300 years, volcanic eruptions and land expansion happened again, with the ocean naturally expanding crazily.
The world will of this small world seemed to focus mainly on ocean development, as most organisms were concentrated there.
The land area was much smaller than the ocean.
This discovery made Yang Yuan wonder if the Earth of the past was also developed with a focus on oceans because life emerged from the sea?
Of course, this thought just flashed in his mind, and he didn’t dwell on it, considering countless years had passed and tracing back was meaningless.
In upgrading from level four to five, not only did volcanic eruptions occur on land, but also in the ocean.
Countless organisms were killed by toxic substances, yet countless others evolved crazily to adapt to the environment.
As a result, some medium to small organisms appeared.
The diameter of the small world doubled again, reaching 800 kilometers.
Afterward, advancing from level five to six caused the planetary diameter to soar to 1600 kilometers. During this period, ocean life frantically adapted to the environment and evolved wildly, with large organisms beginning to appear.
How big were they?
The largest ones were over ten meters long, which would be considered behemoths on past Earth without extraordinary factors.
And in the current small world, it was also a purely natural world with no extraordinary factors.
Perhaps because the essence of this world is the magnetic field, even the yin and yang (sun and moon) are the positive and negative poles of the magnetic field.
Yang Yuan didn’t pause and chose to continue upgrading.
Advancing from level six to seven was very quiet, just like advancing from level three to four, with no volcanic eruptions or land expansion, mainly focusing on biological changes.
