After deciding to go into the water, Yu Zhen looked for some tools from the tent.

There is no need for diving suits and masks, and he can hold his breath for hours now.

The low temperature at the bottom of the water cannot have any impact on him.

He only took some unopened glow sticks.

This kind of facial utensil that uses chemical energy can still be used normally after more than 20 years.

What he perceives and sees with his eyes are completely different concepts. He is still used to enjoying the beautiful scenery under the water with his eyes.

After thumping, Yu Zhen jumped into the cold water.

The lake water was very clear, and the fish, shrimps and insects around him were attracted by the fluorescent light and kept swimming around him. The weeds under the water were like long sleeves waving, dancing gently in the water.

I quickly sank to the bottom of the water and found that the bottom of the lake was very clean. Some jade and beautiful jade hidden in the stones began to reflect the light of the glow stick, making the bottom of the lake look like a dazzling starry sky, giving people a feeling of time and space disorder and the universe being reversed.

But such a clean bottom of the lake is extremely unusual.

According to the principle, fish and shrimp feces should be quite large over the years.

There are also sand and gravel washed by the water flow, which should also be settled here.

With these little doubts, Yu Zhen continued to swim towards the center of the lake.

The closer you get to the center of the lake, the stronger the spiritual feeling.

This is a very aggressive metallic aura. Although it is hidden in deep water, it still gives people a feeling of fierceness and killing.

Soon, he saw something strange in style, standing quietly at the bottom of the water.

It was a tower top shape, about ten meters high, with a simple shape, surrounded by water plants, and some fish and shrimps were hiding in it.

Yu Zhen came to this thing, reached out to touch it, and found that it was made of bronze.

This place should be underground, at least in the belly of a mountain. Why is there such a tall bronze tower?

He released the Yuan Qi and began to perceive it downwards, and the "eye-watching" scene made him feel even more surprised.

The top of this tower in the water is just a small part of a tall tower.

Its tower body is buried deep underground, reaching more than 300 meters downwards!

Moreover, the tower body is huge, with the largest tower bottom diameter exceeding sixty meters!

This is definitely not a product of modern industry, but in the history of ancient China, which dynasty was able to complete such a huge bronze production?

Even if it can be done, why do you need to build it here?

Just when he was confused, a huge golden spiritual energy was released from the spire of the tower, instantly filling the entire underground lake space.

These spiritual energy are not lethal, but Yu Zhen feels unprecedented danger.

Boom-

A huge sound came from the top of the head, and a giant swam out of the rocks above the lake.

This is a giant dragon made of bronze, with a length of 100 meters!

With the blessing of the golden spirit, the bronze dragon's body, covered with copper verdant, became extremely flexible and lifelike.

Before the rocks were fully exposed, it plunged into the lake and came towards Yu Zhen.

The quiet water was suddenly in chaos, with insects, fish and shrimps running away desperately, but the bronze dragon ignored these things. Its body several meters thick was surrounding the top of the bronze tower, knowing that it was blocked by the rocks on the ground, so it began to swim quickly at the bottom of the lake.

It opened its huge dragon's mouth and sucked everything it encountered into its mouth until it cleared the entire bottom of the lake, then sprayed everything into the downward underground river.

Finally, it returned to the bronze tower, but found that it still could not go down, and suddenly became irritable.

Buzz —

A dull sound seemed to be the roar of a dragon. The two eyes, which had no light, suddenly turned into two burning flames.

This is the fire spirit in its body, so there is no need to be afraid of the lake water at all.

The Azure Dragon seemed to have spirituality, and instantly discovered Yu Zhen, opened his mouth and bit it.

Yu Zhen would not let it succeed. He easily avoided it with his thoughts, and at the same time released the Yuan Qi, completely hiding his breath.

The bronze dragon lost its target and the golden spiritual energy in its body was almost consumed. So after wandering around the bottom of the water for a few rounds, it retracted into the rock above.

A huge bronze tower and a swimming bronze dragon made Yu Zhen even more interested.

He felt that this bronze dragon should want to enter the bronze tower, but for some reason, the tower was closed.

He estimated that this tower was originally completely hidden in stone, but it was sucked by the bronze dragon for many years, and a top of the tower had been cleared.

Then go in and take a look.

As for how to get in, this is very simple.

Just release a large amount of metallic spiritual energy to easily blend into bronze, as simple as earth escape.

It took only a dozen seconds before Yu Zhen arrived at the inside of the bronze tower. There was no staircase leading to the upper floor, but was directly hollowed out to the bottom.

The sealing is very good, and there is no drop of water inside.

As soon as he landed on the flat bronze ground.

Before I could feel it carefully, a crisp sound rang above my head.

bite--

Although this light sound was monotonous and simple, it was like a fairy sound from above the sky, which made him feel enlightened.

He felt that practicing mental power should be a good choice in this place.

So he simply sat down on the spot, held his breath, and prepared to enter a state of meditation.

At this moment, the bells and tripods above the head ring, like the sound of the immortals of the Great Dao!

In just a moment, he entered a new spiritual realm.

It seemed that everything in the world could be completely forgotten at this time, allowing him to fly to the vast universe alone.

The endless darkness, occasionally starry lights, is so lonely and lonely.

Slowly, he "come" to a shining star. The star was not big, and there were more than a dozen small stars surrounding it.

The nine closest to them are relatively large, and there is also a comet with a tail that is circling an oblong orbit.

Is this the solar system?

This is the first time Yu Zhen has experienced this experience in this "intuitive" way, and he suddenly feels extremely novel.

So he continued to explore outside and soon found Proxima Centauri, Barnard Red Dwarf, Woolf 359 stars, Brand 2147 stars, Sirius...

Since ancient times, humans have had infinite desire for the starry sky and explored it in various forms.

There were star maps in ancient times, and there were astronomical telescopes and spacecraft in modern times, but none of them were as clear and vast as they are now.

Yu Zhen was immersed in this endless sea of ​​stars and had completely forgotten the time.

He could feel his spiritual power, and through this star tower, it was constantly spreading into the depths of the universe, reaching further and further beyond his ability.

Boom-

Just as he kept exploring, the bronze tower began to rotate, and in the huge internal space, various attributes of spiritual energy gathered into points. According to Yu Zhen's "exploration", it slowly formed a complex and dense starry sky map.
