Mountain Sitting Immortal-Chapter 752: Strong Magnetic Fields.

In fact, many races have tried to invade Aurora, and many have even succeeded in doing so. But the Gem people have always won every war and remained firmly in control of Aries.

Their alertness and preparedness are one of the reasons why they have been able to maintain a strong grasp of Aurora. These are also why they were able to notice the impending arrival of the mothership and prepare for it even before it set foot in Aurora.

To be fair, the special situation of Aurora is the main reason why they were able to notice the mothership even before it arrived in Aurora. This special situation is the strong magnetic field of the Aurora.

Aueor possesses a very strong and active magnetic field. Its strong magnetic field is why it has a larger-than-normal layer of ionosphere in the upper layers of its atmosphere and why there is a perpetual aurora in the sky.

The strong magnetic field was what had caused the end of the spatial tunnel to wobble briefly. The spatial tunnel didn't collapse, but the magnetic field was able to delay the mothership from arriving in Aurora for 10 minutes.

The strong magnetic field made a trip that should have taken less than a minute take more than ten minutes. In that time, the mothership remained at the edge of Aurora and appeared as a large, obscure mass getting closer and closer to Aurora.

When the gem people saw the large, round, and obscure image in the sky, they thought that a giant beast was trying to invade Aurora. What they thought of it didn't matter much, though. What mattered was that they were going to fight the invader.

So the first fortress that noticed the invasion rang the alarm to inform those nearby of the invasion. Then the surrounding fortresses also began to ring the alarm.

The alarm spread outward like that. So in no time, an alarm was ringing all over Aurora. Because of the alarm, even those who were too far away to see the invading beast knew about its appearance and began preparing to repel it.

It would take a long time for the fortresses far away to respond to the alarm and arrive with troops to fight, but for the fortresses that were directly beneath the large and round obscure object in the sky, ten minutes was more than enough time to assemble.

In those ten minutes, an area with a 100-kilometer diameter beneath the mothership had mobilized its troops and prepared for battle. Not every soldier in every fortress in this region was able to assemble in this short amount of time, but the strongest gem people were able to make it in time.

All of them assembled in the same location directly under the mothership. As for the gem people that could fly, they rose into the air to await the arrival of the enemy. Since their fortresses were already standing at a high altitude, they were able to rise even higher into the sky to wait.

Aurora's strong magnetic field also made the layout and the geography of the world different from normal. Because of the strong magnetic field of the world, there is a large magnetic wind current that moves around the world like water in oceans.

There are also islands in these magnetic wind currents. The islands are made of magnetite, which is incredibly magnetic. This makes the islands capable of floating in the magnetic wind currents.

There are large islands that are stable and rarely move in the magnetic wind currents, and there are small islands that go with the flow of the magnetic wind currents like ships. Both of them float in the large invisible ocean that covers the entire surface of the world and form a layer called the highlands.

The highlands are above and block the light of the sun, while the lowlands are below and are dark because of the lack of light. The fortresses of the gem people are in the highlands.

The advantage of the high ground makes it easy for them to respond to invasions like this. Plus, the magnetic wind currents can be used to move and transport things around the world.

These two advantages, combined with their alertness and preparedness, are why the mothership met an army waiting for them when they entered Aurora.

As if this wasn't bad enough, the strong magnetic field was also disrupting mana and making everyone feel uncomfortable. Things were so bad that the golden core within them tried to explode.

The strong magnetic field was also affecting the foundation establishment cultivators with life seeds within them. But the worst thing that happened to them was for mana to leak out of their life seed and flow out of their bodies before joining the magnetic winds current.

But the golden core cultivators were experiencing a worse experience. This is because their golden core contained energy with a higher quality and was tightly bound to their golden core.

The forceful ejection of energy from their golden core will only cause it to explode. So they had to concentrate with all of their mind in order to prevent their cores from leaking any energy in order to prevent them from exploding.

Thor, in particular, had it worse because of his weak mind. Because he had hastened the development of his energy core ahead of his natural cultivation speed, his mind couldn't keep up with his strength.

It was like the time he was controlling a peak third rank golem with the mind of a second mortal coil cultivator. Now, he was controlling a tenth transformation energy core with the mind that is at the third transformation.

This shouldn't have been a problem because the energy core is a part of his body now. But the strong magnetic field current snatched control of the energy core and made it discharge all of its energy at once. So his situation quickly turned into him having a bomb within him.
