Chapter 1609 The Natural Barrier of Thersorn
The Sersorn star system is vast.

While individual stars may not have abundant resources, the overall energy reserves are sufficient and balanced due to the large number of satellites.

Logically, such a "fat piece of meat" would easily be targeted by a civilization that has just entered the star level and is in a stage of resource scarcity.

But in fact, Thersorn has never experienced a real large-scale foreign invasion in its development to this day.

All of this is due to the unique geographical disadvantages of Sersorn: the star field is filled with magnetic nebulae, and once you enter, you will be caught in the violent and chaotic electromagnetic field, which will eventually destroy your ship and kill you, making it a losing proposition.

While these violent electromagnetic storm fields were a disadvantage against external forces, they served as a natural barrier for the early stages of civilization in the Thersorn Cluster, keeping dangerous external forces at bay and providing them with a stable window of opportunity for development.

Subsequently, with the development and progress of civilization, the Sersorn gradually mastered the eruption patterns of the turbulent magnetic nebula, using the natural magnetic storm field as an outer defense, and step by step built the current star field pattern.

During their escape from Annemo, Lin Fan and his group encountered a massive turbulent magnetic nebula.

Pale gray-purple misty clouds covered the sky, looking dreamlike, but in reality, they concealed danger.

To avoid the spacecraft being interfered with by magnetic fields and gravity, which could lead to fatal malfunctions such as electronic instrument failure and circuit burnout, they originally planned to travel around the weak magnetic field at the edge of the nebula.

Unfortunately, the dilapidated spaceship malfunctioned frequently and was difficult to control. In the end, it crashed into the thin mist area on the outer edge of the nebula, grazed the edge of the strong magnetic transition, was slightly pulled by gravity, and was thrown into FW-73.

It's all thanks to Lin Fan's extraordinary skills; anyone else would have been dead eight hundred times over.

Large swaths of turbulent magnetic nebulae were constantly moving and erupting on the outskirts of the Sersorn star system, and ordinary small and medium-sized starships had no way to suppress them.

Large engineering ships can activate high-power energy fields and directional repulsive forces to temporarily calm the high-speed rotating particles with disordered magnetism and forcibly open a short-term channel.

However, this operation can only be applied to the outer buffer zone. Moreover, this operation is short-lived, energy-intensive, and once the energy is removed, the nebula will return to its original state, making it extremely cost-effective.

Advanced civilizations do have better breakthrough mechanisms, but those at level four and above are no longer obsessed with resource plundering and are focused on pursuing higher levels of civilization advancement, so they do not pose much of a threat.

The unique geographical environment helped the Sersorn ward off external enemies, but it also brought them unique troubles.

The entire star field is filled with regions of weak space, nebulous turbulent zones, gravitational distortion points, dense areas of interstellar dust, and gravitational equilibrium points of celestial bodies.

Those points, whether visible or invisible, vary in form, but because of their weak spatial structure, they are all prone to forming temporary spatial fissures.

The crack itself is not scary; what is scary is the spatial channel that is accompanied by spatial oscillations and the leakage of energy from the displaced field.

This might not convey a concrete sense of crisis, but if we say that the Zerg rely on the spatial pull of these channels to deploy their forces and invade planets, wouldn't that create a vivid image?
These Zerg tunnels are not standard interstellar wormholes, but rather temporary wormholes built on weak points in space, belonging to the category of spatial rifts.

They typically have no fixed coordinates, appear randomly, have varying channel sizes, and their lifespan depends on the local spatial field energy, ranging from a few hours to several days.

Just like in a fabric, where the yarn is sparse, holes are easily formed, and things from the back of the fabric can easily seep through the holes.

Cracks naturally form in interstellar space, but there are just a lot of them in the area of ​​Thersorn.

This is also one of the reasons for deterring foreign invaders: after going through great lengths to break in, they still have to be constantly on guard against the Zerg that could appear anywhere...

Instead of spending so much effort, it would be much faster and more convenient to just go to the nearby stars like Annemo.

These Zerg invaders, who came from spatial rifts, are completely different from the Gros who invaded Lan Star.

Most of them lacked high intelligence, relying solely on instinct to invade, reproduce, and even kill each other, causing considerable suffering to the early stars of Thersorn.

However, with the development of civilization, people have studied the laws of rift channels and mastered the method of destroying spatial channels: as long as the spatial base around the spatial rift is destroyed and the ex-situ energy is offset, these temporary channels will shrink and collapse on their own.

Then, in key high-risk areas, a matrix of small floating base stations will be deployed as gravitational anchors to continuously release directional weak gravitational fields, creating a stable magnetic field grid to suppress and block them.

This is like adding reinforcing framing to a loose wall, tightening and shaping the originally loose spatial structure, and increasing its strength. When the Zerg attempt to tear through space and create a passage, the reinforced weak areas will significantly increase the difficulty of tearing, directly preventing the creation of most small temporary wormholes.

However, not all punctuation marks work consistently.

The reason why Zerg wormholes are formed, besides the weak spatial structure, is also due to the continuous outflow of extraterrestrial energy.

In other words, the space on the Zerg side was constantly expanding and compressing outward due to an irresistible force, until a weak point was successfully breached, and the Zerg emerged through the channel opened by the alien energy and maintained continuously.

When ordinary sealing methods fail to stop excessive extrinsic energy, wormholes become inevitable.

At this point, it is necessary to actively project a reverse force field generator or a negative gravity energy bomb into the fissure. Inside the wormhole space, the leaking ectopic energy is counteracted and neutralized to establish a reverse traction, break the channel balance, and cause the wormhole to collapse, shrink, and eventually disappear.

But simply blocking it won't stop it.

The enormous anatomical energy is completely beyond the control of individual will; it continues to expand, accumulate, and surge outward, eventually finding a breakthrough.

Therefore, Sersorn carefully arranged and actively channeled the energy: at the edge of the star field, in the gaps of the turbulent magnetic nebula, he deliberately left enough weak points specifically for the release of detached energy.

Meanwhile, on the inner side, a closed composite force field was established, consisting of numerous space stations and fixed fortresses. This field was designated as the front line of the battlefield, allowing for real-time monitoring of the Zerg's movements and limiting uncontrollable threats to a controllable range.

In this way, the turbulent magnetic nebula and the spatial rift together form the first natural line of defense for the Sersorn star system.

Border fortresses serve as a second artificial line of defense. They can not only monitor and control the spatial activity of the surrounding area, but also form a certain ring force field to prevent the massive wormhole rift from extending into the star field, thus keeping the war firmly at the edge of the star field.

The Noah was able to enter safely because it had connected with the official Sersorn and established real-time migration coordinates.

Otherwise, if Therthorn could simply shut down a nearby matrix magnetic field or randomly open a rift wormhole, the unsuspecting Noah would not benefit much.

It can be said that after years of development, Therthorn has formed a mature defense system.

Apart from the unavoidable incursions of alien beasts on the borders, which necessitate the deployment of sentries to guard and defend the area year-round, most areas within the star field remain stable.

However, nothing is absolute.

The only current solutions for the wormhole problem are "dredging" and "blocking," which have not been able to completely eliminate the threat of wormholes.

Aging equipment, sudden spatial vulnerabilities, and powerful impacts from external energy sources can disrupt the stable order of life from time to time, bringing safety risks.

Local residents are used to this, and nearby sentries even see it as an opportunity to make a name for themselves.

But for the crew of the Noah who were seeing this scene for the first time, everything was extremely novel.

This large wormhole rift appeared near the host planet Prim, and all surrounding shipping lanes were completely blocked. The Noah's departure plan had to be put on hold, waiting for the wormhole to close completely.

When Antonio found out, he was all excited again, jumping around as if he couldn't wait to get to the scene and find out for himself.

Noah also decided to take advantage of this rare opportunity to observe the enemy-repelling process of the Rift Wormhole up close.

Happy Children's Day!! (*^▽^*)
The story of Thersorn is basically over, and a new volume has begun, haha.

Fight! Fight! And the foreshadowing I planted eight hundred years ago is finally about to be revealed.

I hope you all enjoy the new story.

Love you all! (heart emoji)
