In the bizarre four-dimensional time and space, in the endless river of time, there are ups and downs of time.

Here time loses its absolutes, and dimensions are unpredictable.

On the long river of new human time, the timeline that diverged from 2011 A.D. is dense like the Ganges sand.

The Ancient Snake is still on the nearby timeline, devouring the low-dimensional information in it, and after years of research, scientists have also discovered some secrets of the Ancient Snake.

The low-dimensional information in the timeline is a kind of "food" for the ancient snakes of the time.

To be precise, the ancient snake is stripping away the time state of three-dimensional space-time, which is why after being devoured, there are only irregular fragments left inside, and these irregular fragments are still difficult to repair.

The reason for this is that it is stripped of the state of time, or the information of the rules of the existence of the universe, which is equivalent to the loss of the "soul" of a time node.

The purpose of the ancient snake devouring these time states is naturally for eternity, and if it does not devour the time state for a long time, it is very likely to die completely.

Yin Donghua put down the latest research report in his hand, the four-dimensional creature of the ancient snake is not a single individual, but a huge population.

Their footprints are all over the four-dimensional space-time.

In the biosphere of the primitive carbon-based planet, there are parasitic scavenging bacteria and fungi, which are the lowest level in the biosphere and an important component of the entire biosphere.

The ancient snake family, in the ecological niche of the four-dimensional space-time, is similar to the microorganisms of the carbon-based planet, assuming the function of space-time decomposers.

In Yin Donghua's view, whether it is four-dimensional space-time or three-dimensional space-time, the interlocking ecosystem is an inevitable mechanism to maintain the dynamic balance of dimensions.

The ancient snake that constantly devoured the period inside the timeline quickly cleared the creatures of three-dimensional space-time, which could effectively suppress the scale of three-dimensional creatures and strangle a large part of the civilization in three-dimensional space-time before ascending.

This brutal purge is an indispensable mechanism for any dimension.

Without this elimination mechanism, the creatures of all dimensions, under the long-term reproduction, will not only explode in number.

With the passage of time, the best of these creatures will also complete the transformation of the civilization level at a certain moment.

In this way, it will inevitably lead to a very terrible phenomenon, that is, the continuous promotion of low-dimensional civilizations to high-dimensional civilizations.

Since there is a zero-dimensional of the lowest dimension, there must also be a highest-dimensional dimension, and when all civilizations are promoted to the highest dimension, the civilizations that have entered this stage are already unable to ascend.

It's like in the blue star of the Common Era, humans occupy the highest ecological niche, and if one day, the dynamic equilibrium in the ecosphere fails.

Cyanobacteria multiply wildly in water bodies and evolve into cyanobacteria people; Trees cover the entire landmass, solidifying carbonaceous gases in the atmosphere; Underground are swarms of rat-men......

The ecological balance is out of balance, and the consequence is that the entire planet will enter an hopeless death after the final madness.

If we say that the Blue Star in the Common Era has a difficult way back, that is, to advance to the interstellar civilization stage, so as to expand the resources of the ecosystem and delay the arrival of the ecological collapse.

And the civilization that has been promoted to the highest dimension, once there is an ecological imbalance, there is really no way back.

Due to the self-balancing mechanism of each time and space, the interlocking dynamic equilibrium is the basis of the universe that must exist.

The Ancient Snake is the decomposer in the four-dimensional space-time, specializing in clearing the low-dimensional creatures in the timeline to ensure that there will not be too many low-dimensional civilizations to advance.

As for those civilizations that have successfully promoted, they are naturally in charge of the top predators in the four-dimensional space-time.

Because the promoted civilization will inevitably crowd out the ecological niche of these apex predators, the contradiction between the two is natural and difficult to reconcile.

Whether it is the promotion of civilization to victory, or the original predator to maintain position, in the struggle between the two, it is very likely that one side will be eliminated, or even both will be killed.

In this way, the ecological balance of the dimension can be maintained.

……

Yin Donghua, who was in thought, was awakened by a prompt sound.

[Researcher Chen Fen from the Institute of Four-Dimensional Biology came to visit in Conference Hall 106.] ］

The people of the Four-Dimensional Biological Research Institute? Yin Donghua hurriedly unfolded the dimensional passage and flashed into the past.

In the 106 conference hall, five scientists were sitting in their seats, discussing in a whisper, and Yin Donghua's figure appeared.

A short-haired female scientist among the five stood up and stretched out her hand to him: "Team Leader Yin, I'm glad to meet." ”

"Researcher Chen has been waiting for a long time." Yin Donghua also stretched out his hand, and the two of them shook it lightly.

Chen Fen didn't say any nonsense, and directly explained his intentions: "This time I led the team here to test the product just developed by the institute, which is the approval document of the Science and Technology Commission and the Ghost Secret Service. ”

After taking the document and flipping through it, and after confirming that it was correct, Yin Donghua took Chen Fen and the five of them to the Dimension Harbor, which is a special internal facility for the Ghost Secret Service, and it is also the only way to go to the Four-Dimensional Satellite City.

The group took a time ring spaceship, set off from Dimension Harbor, and entered the bizarre four-dimensional space-time.

After about 5 hours of time inside the spaceship, it entered a large and concealed time ring base.

This base floats in a four-dimensional space-time, with a radius comparable to a cosmic island, but this scale, in front of the timeline, is like a bacterium with a diameter of several hundred nanometers on a 12-lane highway.

The base is codenamed "Four-Dimensional-Tianshui Satellite City", which is under the jurisdiction of the Ghost Secret Service, and its main function is to be a transfer station for four-dimensional space-time, monitoring the ancient snake and the surrounding area.

As soon as Yin Donghua got off the spaceship, he took the group to the monitoring center of the base, and after explaining his intention to Su Xiaoguo, the head of the base, he exchanged the current situation of the ancient snake in the period.

Looking at the period ancient snake on the virtual display screen, Chen Fen turned his head: "I basically understand the situation of the period ancient snake, I also brought the experimental product, can I arrange the experiment recently?"

Su Xiaoguo checked it, looked up and said a time: "There is a time period in 6 days, about 83 minutes." ”

"83 minutes? Not enough, I need at least 17 hours. Chen Fen frowned slightly.

"Is that so?" Su Xiaoguo can only readjust the project schedule, adjusting some unimportant projects and those that can be postponed to the back.

"15 days later, 20 hours."

"Thank you very much." Chen Fen nodded.

"It's a matter of duty."

After arranging the date of the experiment, Chen Fen and the others did not leave, but continued to prepare in Tianshui Satellite City, and she attached great importance to this experiment.

Similarly, Yin Donghua also stayed here temporarily, and he received instructions from the headquarters to cooperate and ensure the smooth progress of this experiment.

Half a month has passed in a blink of an eye.

In the vastness of the four-dimensional space-time, there is still a strange place.

The researchers brought by Chen Fen carried out a final inspection of the experimental products and then sent the equipment into a time-ring spacecraft.

The unmanned time loop spacecraft departed from the dimension harbor of Tianshui Satellite City and sneaked towards the dense timeline in the distance.

At this time, in the monitoring center of Tianshui Satellite City, Chen Fen, Yin Donghua, Su Xiaoguo and others were all waiting for the spacecraft to arrive at the designated location.

After about 3 hours, the ship finally arrived near the Ancient Snake.
