Tossing and turning, crossing the grassland.

It took Yue Guanchao and them half a month to follow the convoy of Yongsheng Commercial Bank across the steppe to the snow-capped mountains northeast of Lake Baikal.

At this time, it is August and September, and the autumn of Lake Baikal is coming, and the pine forests everywhere are dyed, as if the mountains are burned and beautiful, and the surface of Lake Baikal in the distance is as flat as a mirror, rippling with the blue sky, and the lake water occasionally hits the shore, stirring up countless snow-white splashes.

If you look further to the northeast, you can see the snow-capped mountains stretching from the West Siberian Plateau, along the streamlined Lake Baikal, scattered in the basin between the banks of the northeast corner, forming a geographical landscape of snow-capped mountains and basins.

It can be seen that the upper forests of the basin are full of beauty, and then look up at the high mountains, the autumn wild mountains around the basin are creeping below, and the snow-white and cold kaolin snow mountains are layered together, like the gods standing quietly by the lake in the distance.

Their car stopped in a mountain basin not far from the snow-capped mountains, and then entered the nearby ancient city of Yasa!

According to John Hua, the ancient city of Yasa is the northernmost town of the Mongolian steppe, and beyond that, there is the inaccessible West Siberian Plateau, which is beyond the real border.

The ancient city they went to was mainly inhabited by the Yasa people, belonging to the northernmost nomadic people of the Mongolian people, and the towns they lived in were also called Yasa or Yasa City, in addition to the ancient city where they were located, there were also many large and small Yasa cities scattered on the northern grassland, but the scale was not as large as the ancient city of Yasa where they were located.

The city of Yassa, where they lived, is called the ancient city because it has been a settlement of the Yasa people since the time of the previous dynasties, and the pastures on the shores of Lake Baikal are rich and woodland, and they do not need to migrate to distant places to graze and live, and for hundreds of years, they have formed a semi-sedentary and semi-nomadic life, and they have lived in this ancient city for three or four hundred years.

When you enter the city, you can see that the structure of this ancient city is circular, and the streets in the city have not been planned, but have been divided according to the outline of natural buildings for hundreds of years.

The houses are arranged along the streets in all directions, and most of the houses are two-story stone buildings or simply single-storey wooden buildings, leaving few gaps between them, and occasionally you can see a few steeped churches, rippling with clear and distant bells.

As you walk, you can see the tall chimneys in the courtyards of the buildings everywhere, and they smoke billowing up, making the sky over the whole ancient city ethereal and unreal, and the clouds and fog are around.

Along the city wall of the ancient city of Yaku, you can also see the dome tents scattered everywhere in the grassland, as if the outside of the city wall is scattered with mushrooms of different sizes, it can be seen that the Mongolian people are mixed and gathered, cattle and sheep are herds, livestock are everywhere, noisy into pieces, it can be seen that in addition to the Yasa people, there are many people living in various banners and tribes of the grassland, and it is also an ancient city with many ethnic groups.

They entered the ancient city, found the inn where some caravans rested, sent most of the things into the inn room, and were led out of the ancient city by John Hua to the nearest snow-capped mountain to them.

Near the shores of Lake Baikal, they learned why Baikal was called the North Sea.

This lake is hundreds of kilometers long before and after, and the widest part is also forty or fifty kilometers, shaped like a crescent moon embedded in the Siberian plateau, any river and lake on the Mongolian steppe can not be compared with him, as long as someone crosses the vast steppe to the northernmost point, it is absolutely impossible to ignore Lake Baikal, with his huge size, it is reasonable to say that it is the ocean located at the northernmost tip of the steppe.

For thousands of years, Lake Baikal has always been the pearl of the steppe of the Mongolian people, the jade of the snowfield, and the North Sea of the Central Plains civilization.

As mentioned earlier, during the period of Emperor Wu of the Han Dynasty, Su Wu was not afraid of the power of the Huns, shepherding sheep here for 20 years, after he returned to the Han Dynasty, he observed the situation in the North Sea, as well as the situation of the grasslands along the way when he returned, all of which were told to Emperor Wu of the Han Dynasty, so that Emperor Wu of the Han Dynasty had a rough grasp of the national conditions and landforms of the Xiongnu in the northwest and the customs of the people of the grassland, which provided great help for the follow-up Han family to chase the Xiongnu in the north.

In the Tang Dynasty, the Tang Dynasty soldiers exterminated the Eastern Turks, and from then on, the East Turkic territories including the Hexi Corridor in the west, the Xing'an Mountains in the east, the Yinshan Mountains in the south, and the West Siberian Plateau in the north were all under the management of the Tang Dynasty.

At that time, including the area where Lake Baikal is located, was divided into Xuanque Prefecture by the Tang Dynasty, and the local tribal leaders served as the governors and governors of the prefecture, and managed and implemented the imperial system.

In the Yuan Dynasty, the emperor of the Yuan Dynasty also subjugated the people in the forests on the shore of Lake Baikal and divided it into Lingbei Province.

It can be said that although Beihai flows out of the hands of the Central Plains civilization intermittently, it still maintains an inextricable relationship, and has never been truly independent of the Central Plains civilization and Central Plains culture.

At this moment, they are standing on the shore of Lake Baikal, there is always an indescribable mood, Yue Guanchao and Song Siyuan also want to see, why does the ghost island that sometimes appears and sometimes disappears appear in the lake? What secrets are hidden in this lake?

"If you want to find Onijima, why don't you send divers down to have a look?" Yue Ercang pointed to the lake and said.

John Wahat waved his hand at them: "We have tried it a long time ago, the depth of Lake Baikal is far beyond that of ordinary lakes, and the shallowest point is nearly 700 meters, and this is only in the shallow area along the shore of the lake, as for the deeper area, considering the water pressure and depth, we do not dare to dive casually, but judging by the ratio of the depth of the shore to the depth of the bottom of the lake, the deepest depth will be at least more than two thousand meters." ”

Speaking of this, John Hua's face became serious: "At such a depth, it would take four or five buildings to fill in the Empire State Building in New York, which is four hundred meters high, from end to end." ”

Looking at two thousand meters alone, it really doesn't feel anything, and now John Hua has found an example for them, that the Empire State Building in New York is at least 400 meters high, and it can be filled with four or five buildings in a row, which is deeper than the seabed and basin in most offshore areas!

Song Siyuan looked at the map in his hand and said: "This is indeed a bit too weird, most of the lakes are composed of the surface of the confluence of the surface rivers into a relatively gentle depression, even if the area is large, the depth is mostly between ten meters and one hundred and ten meters, this is because the water flow can only erode the surface soil, and it is impossible to wash away the rock layers under the soil layer." ”

A lake like this is more than 700 meters deep at the shallowest point, and the deepest part of it is probably already deep into the underground rock formation, and this underwater structure that is hundreds of meters deep is mostly due to the cracks in the rock layers on the ground, and after the confluence of the surface river, it produces a state similar to a lake.

Since the underground fissures range from hundreds of meters to thousands of meters deep, of course, they have created many unparalleled lake depths, but such structures are mostly found in the depths of the ocean or karst landforms, is Lake Baikal also a huge fissure in the rock formations?

Speaking of this, John Hua's tone became mysterious, and he nodded at everyone and said, "When we send divers down to sneak, in addition to finding traces of Ghost Island, we also need to explore the space under the surface of the lake to see what the cause of the lake is?" Judging from the rock specimens we have obtained, the formation of Lake Baikal is related to geological movements in ancient times, in addition to the injection of surface rivers......"

Tens of millions of years ago, the Indian plate and the Eurasian plate continued to squeeze and collide, resulting in the geological movement of the snowy plateau as a whole, and at the same time, the huge force also caused the internal geological changes of the Eurasian plate, forming a crescent-shaped tearing canyon at the junction of the Siberian Plateau and the Mongolian steppe.

Since the location of the tearing canyon is in the basin, which also makes the canyon the lowest point of the surrounding basin, the surrounding rivers, large and small, began to pour water into the canyon under the terrain drop, a process that took tens of millions of years before the canyon was completely filled and the lake they see today was formed.

John Warlord nodded at the crowd: "If there is no water in Lake Baikal, then it should be an underground canyon thousands of meters deep, and with our current technology, the bottom of Lake Baikal cannot be touched at all." ”

Yue Guanchao questioned: "If there really is a ghost island in Lake Baikal, then it should be completely floating, otherwise this water thousands of meters deep will never float up from the depths of the lake." ”

John Hua shook his head at this, it didn't seem to be very clear, Song Siyuan thought about the situation of the lake and said casually: "Just now John Hua explained that the geological structure of Lake Baikal is due to geological movements in ancient times, I am wondering, can Xianbei Ghost Island appear here?" Is it also related to geological movements? ”

After that, Song Siyuan looked at the snow-capped mountains in the distance, and her eyes lit up: "As far as I know, the name of the Siberian Plateau comes from the Siberian Tatar language, where the Siberian Khanate was once established by the Tatars, and was later conquered by the Grand Duchy of Moscow.

John Hua's eyes became curious, as if he also thought that there was a possibility, Song Siyuan continued: "Plate collision is actually the same as an earthquake, and before and after an earthquake, it is precisely the electromagnetic ......field that changes."

Speaking of this, Song Siyuan's thoughts became clearer and clearer: "Before and after the earthquake, it will cause changes in the electromagnetic field, and at the same time, the electromagnetic field will also affect the changes in the magnetic field of the nearby environment, thus causing the distortion of the magnetic field. ”

Under this geomagnetic influence, these islands have the ability to travel between the mirror world and the real world, and due to the characteristics of the island stones, they have also become a medium of communication between the two worlds.

She paused and guessed: "Then if that's the case, is it that we put the yin and yang fish into Lake Baikal, relying on the mutual induction of Xianbei Jinshi, we can find out the approximate location of the appearance of Ghost Island at the beginning, and we also used instruments to detect the tiger talisman caused by Xianbei Jinshi, and there is indeed an abnormal ability contained in it, which causes changes in the magnetic field and magnetic force, thereby affecting the five senses of the human body!" ”
