Recently, the fleet on the front line of Asgard found that the fleet of the demon clan has been decreasing, decreasing without warning, and the ghost motherships that were several million away from the previous defense line are now estimated to be more than one million left, and the other ghost motherships seem to be missing and disappearing in the past few years.

In a few years, the Asgard side has absorbed a lot of technology from the latest spirit ships of the demons, and has greatly upgraded the fleet of the Asgard, adding energy beam weapons and spirit shields, and most importantly, through the Yuanshen control device, the entire fleet has become a whole.

The biggest breakthrough of Asgard is that after several years of careful research, the space restoration technology can finally be put into practical use.

The research spirit ship where Nuwa's doppelganger is located has contributed a huge amount of power in various studies for a long time, and through the warp speed vehicle in the demon race's brand new ghost mothership, they have synthesized some data on force space, and based on these data, they have carried out a huge amount of evolutionary calculations.

Then, based on these calculation results, we first began to carry out a small-scale space storm repair operation in the space storm of the Archaeopteryx, and through something similar to the star door lock, the research ship made a very safe and stable passage in the space storm, and directly let the research spirit ship reach the vicinity of the original demon channel.

At this time, the demons don't know that this opening can already come out, the most important thing is that this opening is a bit small, compared to the two giant passages on the periphery of the Sky Star Domain and the Tianqiao Star Domain, you can pass through a large number of ghost forest motherships, this passage is too small, only about three kilometers in diameter, a giant ghost forest mother ship can occupy the entire channel, it is very troublesome to go in and out, and only some ground troops can be transported out, no wonder after so many thousands of years, it is the ground forces to toss again, this channel is not enough for the demons to launch a full-scale attack, the last time the demon tide was still due to surprise, human fragility was beaten so badly。

Later, it's not that the demons don't want to attack, but with such an efficiency of transporting troops, they can't attack.

And now, this passage has obviously been abandoned by the demons, because two better passages have appeared, and the large passages that can support the passage of large fleets together are obviously more in line with the needs of the demons.

......

Nuwa, who was at the entrance of the passage, began to experiment with physical objects to her heart's content, and through the theoretical research of the barrier repair device, similar to the star door lock, made one after another, one after another, some will have some effect, some will have the opposite effect, just like that, in a few years, this passage will be big for a while, and small for a while, and these changes have also continuously improved the spatial architecture of Tianfang, Nuwa's database.

In this way, while adjusting and experimenting, dozens of schemes were made, and today finally came to the most critical time.

"Nuwa, do you think it will work this time?" Tianfang asked.

"After so many years of research, there are dozens of variables that have come out of it, and there are no new variables in the last few times, according to my calculations, the probability of success this time should reach more than 99 percent!" In order to be on the safe side, I made five barrier repairers with different data, which can adjust the frequency of the space barrier, and the frequency of the space barrier has also been determined recently, as long as it can cause resonance, it should be able to make the barrier repair itself, and the next time the demon opens it, it will cost a huge price!"

"If we come to completely repair this barrier, how much energy does it take!" Tianfang looked at the data, the barrier repair still mainly depends on the self-healing ability of the barrier, according to Nuwa's calculation, if the space energy is completely provided from the outside to repair, the energy required is massive, it is possible that all the retraction furnaces in the Asgard Palace are added up, and they can't succeed, the initial research direction is this, every time they are thrown in, not even a bubble comes out.

Later, after several times, the problem of insufficient energy was discovered, and he began to change his strategy and use spatial resonance to trigger the self-healing ability of the barrier, of course, it is also possible that the frequency is wrong, causing this self-healing ability to become self-destructive.

......

"The resonator is ready, start to adjust the frequency, and prepare for charging!" Nuwa used the mechanical arm of the spirit ship to place five blocks full of science and technology at the outer entrance of the black hole, in the form of a standard equilateral pentagram.

Each resonator began to emit light, like ripples, spreading outward, and the five ripples formed a convergence point in the middle of the pentagram, and this convergence point began to vibrate, as if passing through space, and the research ship where Nuwa was also began to vibrate.

"Damn, Nuwa retreat quickly, the space in the radiation area has begun to shake, which may lead to the collapse of the space!" Tianfang looked at Nuwa's real-time data, and hurriedly asked Nuwa to withdraw, in case it developed in a bad direction, it would be troublesome.

The spirit ship fled quickly with a long tail flame, and drove hundreds of thousands of kilometers before it could feel the vibration, so it stopped and used ultra-high power telescopes to observe this passage.

There are still many demons on the Ancestral Star, and they have also discovered this vibration, but they don't understand where the vibration comes from, and they can't panic, because this thing can't be isolated, as long as it's in the space area, they will feel it.

Suddenly, a strong light erupted from that convergence point, and the ripples that had originally fluctuated in a small area spread far away, and the milky white ripples were like ocean waves, washing everything around, the first of which was the space storm that had not yet calmed around the passage.

It was as if an invisible hand had smeared a handful on the graffiti on the sand, the entire sand became smooth, the space storm had all subsided, and the space that originally looked like a steaming space distorted and turned into an ordinary space, and the black crack that had to flicker a few times from time to time slowly became smaller, slowly became smaller, became a small bubble, and finally disappeared without a trace.

The black vortex with a diameter of three kilometers, as if something was squeezing, slowly slowed down, and finally stopped, becoming a quiet channel, and then the white ripples seemed to be like an eraser, every time it fluctuated, part of the black channel was partially removed, and the whole channel became smaller and smaller, just under the annotation of the demons, it became a small bubble, and then the small bubble didn't even send out a wave, and it was wiped clean by the eraser.

The milky white ripples continued to shine, and wave after wave of ripples seemed to be filled with a cheerful smile, rushing in the space, as if going deeper into a deeper place, and the originally invisible scars were also repaired little by little.
