After re-entering the Central Belt, the weirdness of last night returned.

But soon, the Bai Qi brothers discovered the source of this strange feeling.

Through the intuitive and concrete visual perception of the surrounding forest landscape, they found that after the sunlight shines in, the light and shadow cast in the forest are equally divided.

That is, next to the sunlight shining in, there will always be an equal amount of shadow area.

Very subtle!

No wonder they felt weird when they came in yesterday evening.

Because it is evening, the light is gradually weakening, so the ratio of light and shadow is unbalanced, resulting in visual persistence.

It is a phenomenon in which the vision produced by light on the retina remains for a period of time after the light stops working.

Therefore, yesterday evening, the two of them still presented the light scene of the previous second in their minds, but the dim scene of the next second was already in front of them.

And because this contrast is gradually reflected in the mind as the afterglow fades away, like a frog boiled in warm water, the two of them felt weird at the time, but they couldn't talk about it.

"The ratio of light and shadow here is almost perfect, and I am afraid it is due to the arrangement of the surrounding trees." Zhuge Xiaoqiang analyzed.

"Does it help you study the Bagua Array?" Bai Qi has awakened and his strength has been greatly improved, and the purpose of training has been basically achieved.

And according to the Great White Tiger, most of the things in the central zone were made by Zhuge Xiaoqiang's father, probably so that Zhuge Xiaoqiang could inherit their family's ancestral formation.

So he opened his eyes to the magic of the Heartland.

"There should be, the changes here are probably the key to the changes that can make the Bagua Array derive." Zhuge Xiaoqiang said.

"Then let's take a look around." Bai Qi said.

"Hmm."

An hour later, the two of them had almost walked through the central area, and the result was the same as when they had just entered, the area of light and shadow in the forest was half and half, almost equal.

And, as the sun continues to rise, the area of light and shadow remains the same, but the positions of the two are constantly changing.

That is, the lighting environment in the whole forest changes with the change of the angle of light.

Therefore, when the Bai Qi brothers returned to the place where they came this morning, the surrounding light and shadow environment had changed, and it felt like they had come to a new forest.

And this feeling will continue to change slowly as the angle of the light changes.

In addition, it is not possible to determine the reference frame because of the seemingly irregular distribution of trees among the species, and the height of the same tree species is almost the same.

However, these are not the root causes of the inflow and inaccessibility of the central belt.

What is extremely strange and grotesque is that under the dual effect of light and shadow changes and the distribution of tree species, no matter which direction you go, you will have a feeling of "walking around and coming back" at the end.

Even if you fly into the air to observe and write down the direction, and then walk in the forest, you will be confused as you walk, and it will seem that you are back to the place you just walked.

And not all places in the forest can fly into the air.

Only areas close to the center will fly into the air without feeling unusual. And the farther away from the central area, the more difficult it is to fly into the air.

Because not only will there be uncomfortable vertigo, but also optical illusions and even hallucinations will appear in vision, making it difficult to fly.

So no matter how they go, they can't get out of the center.

As for the reason, the Bai Qi brothers are still unknown.

After that, except for Zhuge Xiaoqiang, who was still walking around, looking for the reason, Bai Qi and Dandan, they had already returned to the big banyan tree.

Because he couldn't get out of the central area and had nothing to do, Bai Qi thought of the idea system he had advanced and could start trying new skills.

Flying Relics!

So, Bai Qi began to practice the dance under the big banyan tree. By applying the power of the mind to one's own shoes, to make oneself float.

However, this kind of operation requires a more precise control of the mind, and it is a skill that takes a lot of time to get used to.

Therefore, Bai Qi kept trying, and the mental fluctuations constantly acted on the shoes, making them float with themselves.

"Mind control, fly!"

However, the rate of each float fluctuates.

And because he hadn't gotten used to it, he didn't dare to float too high, for fear that if he didn't pay attention and fell down, he would die.

……

In the central zone, after getting up every day, Bai Qi is constantly practicing new skills, and Zhuge Xiaoqiang is also constantly exploring the secret of this place, which can only enter but not exit.

Time passes slowly in this way, repeating the same thing day after day.

Two days later, the Mid-Autumn Festival arrived.

And this day is destined to be written in the history of mankind.

Because, according to the latest observations and studies of scientists, the sun is starting to come alive.

This means that the Xiaoice period is coming to an end!!

As soon as the news came out, the world was in an uproar.

Because the impact of the end of the Xiaoice period is immeasurable.

For example, the end of the Xiaoice period means that frozen water resources will thaw, so that the problem of human water shortage can be quickly alleviated.

Moreover, the water systems in the temperate and subtropical zones will be completely restored, so that the industry and agriculture in these regions will be revived, and the material standard of living of mankind will be greatly improved.

But at the same time, the end of the Xiaoice period will lead to a rise in sea levels, and the adverse effects will be very serious.

The first is the question of how to preserve the recreated continent of the world.

If we don't think of a proper solution quickly, the great western continent will once again be submerged in the ocean.

And this is what all of humanity does not want to see.

Especially those who have lived on this land since their ancestors and established a country here, do not want this land of existence to be submerged.

Because if it were to be submerged, it would mean displacement.

And now on all continents, humans occupy far less land resources than foreign beasts.

Once the people living in the Great Western Continent lose this place of survival, how the people of other continents will accept these people who have lost their homes is a problem, and how to settle them after acceptance is another problem...... Eventually, it will lead to a series of livelihood problems.

Therefore, the Great Western Continent must find a way to preserve it.

The second is the problem of sea monster encroachment.

Once the sea level rises, it will be more conducive to sea monsters invading the coastal areas of various continents.

There are already strange beasts on the land, and when the time comes, coupled with the invasion of sea monsters, humanity will once again be in a severe situation.

And this is obviously more serious than the problem of people's livelihood, and it will be a major event that endangers the life and death of mankind!

However, this is only from the perspective of water thawing, and the impact of the end of the Xiaoice period is already so widespread, let alone all-encompassing.

Immediately, the armies of various countries in the world secretly mobilized to take precautions.
