Basalt has some notable characteristics, that is, it usually appears black or dark green, and there are many small bubble-like holes between the rocks, which look like they have been drilled by small insects.

This is a volcanic rock with a long history, most of which are formed when volcanic magma is ejected.

However, both basalts have different properties and structures.

As far as Wu Liang knows, basalt is actually just a general term. This kind of rock has been divided into many categories in later generations, and different basalts will also show different special features.

Unfortunately, Wu Liang did not major in geology and archaeology, and his understanding of basalt was only superficial, so he was unable to conduct a more in-depth analysis and study of this "fairy mountain".

But it is undeniable that some basalt is indeed magnetic, even strongly magnetic, and the mountain composed of this kind of basalt will naturally form a unique magnetic field, thus affecting everything around the mountain.

In later generations, there was a similar valley in China.

That valley is called Nalengela Canyon. It was once known as the "Gateway to Hell" and also known as the "Kunlun Death Valley". It is very famous throughout the world.

It is said that the Narengrad Canyon is filled with wolf furs, bear bones, hunters' steel guns and lonely graves on barren hills, while the herdsmen living in the Kunlun Mountains would rather let their cattle and sheep starve to death in the Gobi Desert because they have no fat grass to eat.

He dared not let him enter the Kunlun Mountains, an ancient and silent valley with lush pasture.

Even the geological team that went to work nearby encountered terrible things when they entered the valley, and some people almost died in it.

Later, after an investigation by professionals, it was finally discovered that strong magnetic basalt is distributed in this area, so the magnetic anomalies are extremely obvious and distributed over a wide range. The deeper you go into the valley, the higher the geomagnetic anomalies are. And those in the "Kunlun Death Valley"

The death incident is most likely related to the strong magnetic field in the canyon... But so far, this is just a theoretical speculation, and no one has come up with the most direct evidence.

Until this moment.

Wu Liang finally found out the cause of the abnormality in the compass.

But at the same time, he also began to feel slightly worried.

Could the terrible things Big Dog encountered before be related to this abnormal magnetic field? Will the parallel small world also be affected by the magnetic field?
