After entering the huge hole of the Earth Element Realm for more than ten minutes, Zhang Tie felt a huge suction force coming, this suction force did not come from the impetus of the air flow, but from the change of the magnetic field in the cave, Zhang Tie felt like he was sitting in a magnetic elevator, and he didn't need any strength, the whole person was pulled and wrapped by that force, and fell towards the underground world like lightning.

The key to entering and exiting the passage of the Earth Metaverse is to relax, so Zhang Tie did not deliberately control his body, just like drifting down in a boat, allowing himself to wander in this strange passage.

In such a state, even if you don't want to relax, you can't move, just like a person in an elevator can't jump out of the elevator, and a qiē in this passage can't jump out of the shackles of this passage.

Not even a knight, this is the mysterious and majestic power of heaven and earth.

In the Mountain of Light, Zhang Tie saw 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 spiritual power seemed to be frozen in this strange passage.

After trying a few times, he found that this was the case, and Zhang Tie completely gave up struggling.

No one knows why there is such a passage, just as no one knows why the stars in the universe are all round, the age of this passage. As old as this planet, it seems to be one of the original faces of this world—like a depression in the middle of the upper and lower ends of an apple. Most fruits have such a depression, can you wonder why there is a depression in the middle of the upper and lower ends of those fruits? You would say it's genetically determined. So, who determines the genes of the fruit? Is the shape of the fruit the self-evolution and replication of the fractal composition of this planet?

After the cataclysm, when the magnetic poles of this world were deflected, the world was turned upside down, and the thick layer of ice and snow covering this passage completely melted, and this passage was completely revealed. Before the cataclysm, this was not Bingzhou, but one of the poles of the planet. Most of the current Eastern Continent is the former Polar Continent.

……

In this passage, Zhang Tie felt that he was stationary, because the relative distance between the knights and the flying boat who entered with him around him did not change at all, and everyone seemed to be stationary, but in this seemingly static state, everyone could see strange underground light and shadow bands "crashing" towards him, and they were pierced by his own lightning in the blink of an eye......

The speed is too fast, fast enough to use Zhang Tie's spiritual power. It was completely impossible to see what the scene around this passage was, and all the scenes had turned into blurred patches of light and shadow.

On several occasions, when I focused the perception of mental power and the knight's heart to the maximum and looked at the surroundings. Zhang Tie felt as if he had passed through a hollow layer hundreds of kilometers thick and full of lightning, why was there lightning underground. Zhang Tie didn't know.

That layer of hundreds of kilometers of underground lightning, at the speed of the time. It's only a few tens of seconds away.

In addition to this, there are some strange things that have appeared......

Over here. Time seems to have slowed down......

Whether it is under the Island Dragon Cave or the place where Zhang Tie discovered the Tower of Time under the Karré Mountains, it is theoretically in the crust of this planet or close to the mantle, but here, it has gone deep into the crust and entered the most mysterious inner area of this planet.

For almost three hours, Zhang Tie didn't know that he had gone tens of thousands of kilometers underground, but suddenly, the speed of decline slowly slowed down, and then, after only more than ten minutes, everyone's bodies suddenly loosened, and the restraint from the mysterious passage that bound everyone disappeared at once, whether it was a knight or a flying boat, they suddenly regained their ability to move, and they all stabilized their figures.

In the violent air flow blowing downward, everyone was suddenly sprayed into a vast space.

What caught Zhang Tie's eyes was above the dome of the sky in this space, a cloud glowing with red light, and below the mountain, there were high and continuous hills, and on the horizon in the distance, it was faintly seen that it was a piece of light.

The flying boat and the knights who came down here all flew towards the place where there were lights in the distance, and Zhang Tie followed unhurriedly.

When he flew closer, Zhang Tie saw that the place with lights was completely a huge fortress ten times more majestic than the first-class city on the ground.

The whole fortress, as if it had been standing there since ancient times, has an air of vicissitudes but mystery.

The city wall of the fortress is thousands of meters high, the whole fortress, layer upon layer, occupies tens of thousands of square kilometers of land, chokes a throat place, and you can't see the end at a glance, there are dense towers of all kinds in the fortress, and those dense towers of all sizes are like the spikes on the hedgehog's body, one by one rising to the sky, with a chilling momentum.

This fortress is not at all built by manpower, because the entire fortress, including the tall towers in the fortress, shines with a metal-like luster, and this is actually a fortress made entirely of metal.

Until today, even if the capabilities of human science and technology before the cataclysm are added, it is impossible for human beings to create such a magnificent fortress of pure metal, covering an area of tens of thousands of square kilometers, which is completely beyond the limits of human imagination.

Not to mention construction, Zhang Tie even doubted that even if the steel reserves in all the Grade A cities in Taixia were added together, they would not add up to the weight of this fortress.

Neither the humans of this era nor the humans before the Cataclysm were capable of making such a thing.

There is no doubt that this fortress is a prehistoric relic of the Earth Metaverse, a product of an unknowable and distant civilization.

In the middle of the fortress, which is also the highest point of the fortress, there is the largest metal pyramid that Zhang Tie has ever seen, and in the distance, opposite this fortress, there is another mysterious and boundless world-the Earth Metaverse.

This is the Lion Fortress, the most magnificent fortress of the entire human race, the prototype of the war fortress of this era of mankind, and the most solid fortress of the entire Eastern Continent and Taixia in the underground world, it is not only the gateway for human beings to enter the Earth Metaverse, but also the throat of the Earth Element Realm to the surface of the Eastern Continent.

If this strongest fortress and shield are breached, it means that the army of the demon race 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 also opened the door to the underground world and became the strongest bridgehead for human exploration of the underground world.

In a sense, the Lion Fortress is the hope of the human race against the demons.
