More than ten minutes after entering the huge cave entrance of the Diyuan Realm, Zhang Tie felt a huge suction force. This suction force did not come from the push of the air flow, but from the changes in the magnetic field inside the cave. Zhang Tie felt
It was like he was sitting in a magnetic elevator. Without any effort from him, his whole body was pulled and wrapped by that force, and he fell towards the underground world like lightning. ↖
The key to entering and exiting the Diyuan Realm passage is to relax, so Zhang Tie did not deliberately control his body, just like drifting down on a boat, letting himself wander in this strange passage.
In this state, even if you don't want to relax, you can't because you can't move at all. Just like a person sitting in an elevator cannot jump out of the elevator, everything in this passage cannot escape from the constraints of this passage.
Not even knights can do it, this is the mysterious and majestic power of heaven and earth.
In the Mountain of Light, Zhang Tie read an article that it was impossible for a four-wheeled knight to try to move in this passage, let alone an ordinary black iron knight.
Zhang Tie tried it and found that even his mental power seemed to be frozen in this strange passage.
After trying it several times, he found that it was indeed the case, and Zhang Tie gave up the struggle completely.
No one knows why there is such a passage, just like no one knows why the stars in the universe are all round. The age of this passage is as old as the planet, and it seems to be one of the original features of this world——
Just like the depression in the middle of the upper and lower ends of an apple. Most fruits have such depressions. Can you wonder why those fruits have depressions in the middle of the upper and lower ends? You would say it is genetically determined. So, yes
Who determines the genes of fruits? Is the shape of fruits the self-evolution and replication of the different types of this world and planet?
After the Cataclysm, when the magnetic poles of the world deflected and the world was turned upside down, and the thick layer of ice and snow covering the passage completely melted, the passage was completely revealed. And the Catastrophe
Before, this was not Bingzhou, but one of the poles of the planet. Now most of the Eastern Continent was the former Polar Continent.
…
In this passage, Zhang Tie felt that he was still, because the relative distance between the knights who entered with him and the flying boat did not change at all. Everyone seemed to be still, but just in this seemingly
In the still state, everyone can see the strange underground light and shadow strips "colliding" towards them, and they are penetrated by them in the blink of an eye like lightning...
The speed was so fast that even with Zhang Tie's mental strength, he could not clearly see what was happening around the passage. All the scenes turned into blurry patches of light and shadow.
Several times, when Zhang Tie concentrated his mental power and the perception of the knight's heart to the maximum extent and stared at the surroundings, Zhang Tie felt as if he had passed through a hollow layer hundreds of kilometers thick and full of lightning. Why is there such a thing underground?
Lightning. Zhang Tie doesn’t know.
The hundreds of kilometers of underground lightning layer passed by in just tens of seconds at the speed at that time.
In addition, there are some strange things that have appeared...
Time seems to slow down here...
Whether it is under the Dragon Cave on the island or where Zhang Tie discovered the Tower of Time under the Kalei Mountains, they are theoretically within the planet's crust or a place where the crust is close to the mantle, but here, it has already penetrated deep into the earth's crust.
, entering the most mysterious inner region of this planet.
For almost three hours, Zhang Tie didn't know that he had gone tens of thousands of kilometers underground. Suddenly, the speed of descent slowly slowed down. Then, just over ten minutes later, everyone suddenly felt relaxed.
The constraints from the mysterious passage that bound everyone suddenly disappeared. Whether they were knights or flying boats, they suddenly regained their ability to move and stabilized their bodies.
In the violent air flow blowing downward, everyone was suddenly sprayed into a vast space.
What caught Zhang Tie's eyes was the glowing red cloud on the dome of the sky in this space. Under the mountain, there were high and continuous hills, and on the horizon in the distance, there were faint
I could see it was a field of lights.
Feizhou and the knights who came down here all flew towards the place with lights in the distance, and Zhang Tie followed them unhurriedly.
After flying closer, Zhang Tie saw that the area with lights was a huge fortress that was ten times more majestic than a Class A city on the ground.
The entire fortress seems to have been standing there since ancient times, with an aura of vicissitudes but mystery.
The walls of that fortress are thousands of meters high. The entire fortress is layered on top of each other, occupying tens of thousands of square kilometers of land. It strangles a choke point and can't even be seen at a glance. There are densely packed trees in the fortress.
Various high towers, those densely packed with large and small towers, are like the sharp thorns on a hedgehog, rising into the sky one by one, with a chilling momentum.
This fortress cannot be built by manpower at all, because the entire fortress, including the high towers in the fortress, shines with a metallic luster. This is actually a fortress made entirely of metal.
To this day, even if the capabilities of human science and technology before the cataclysm are added, it is impossible for human beings to create such a pure metal majestic fortress covering an area of tens of thousands of square kilometers. This fortress has completely exceeded
reaches the limit of human imagination.
Not to mention construction, Zhang Tie even doubted that even if the steel reserves stored in all Grade A cities in Taixia were added together, the total weight would be as heavy as this fortress.
Neither humans in this era nor humans before the Catastrophe have the ability to create such a thing.
There is no doubt that this fortress is a prehistoric relic of the Earth Yuan Realm, a product from an unknown distant civilization.
In the middle of the fortress, which is also the highest point of the fortress, stands the largest metal pyramid that Zhang Tie has ever seen. And further away, opposite the fortress, is another mysterious and boundless world——
Earth Yuan Realm.
This is the Lion Fortress, the most magnificent fortress in the entire human race, the prototype of the battle fortress in this era of mankind, and the most solid fortress in the entire Eastern Continent and Taixia in the underground world.
It connects the Diyuan Realm to the surface of the Eastern Continent.
If this strongest fortress and shield is breached, it means that the demon army will be able to appear directly on the surface of the Eastern Continent and directly attack the core area of the human country. On the contrary, the existence of this fortress will also open up the underground The gate to the world has become the strongest bridgehead for humans to explore the underground world.
In a sense, the Lion Fortress is the hope of the human race to resist the demon race.
