The further underground it became, the more tortuous and rugged the tunnel became, and many places collapsed and blocked, and the Tiger God team made a hole that was just enough for one person to pass through, and it was necessary to use both hands and feet to drill through it with difficulty.

In the endless darkness, the faint light of the underground spars that occasionally leaked out from the tiny cracks next to the tunnel was like slender eyes embedded in the cave walls, staring at these explorers without blinking.

Li Yao and the six of them moved around on the cave wall at an extremely fast speed, and after half an hour, they came to 9,500 meters underground!

Despite all the mental preparations, the six of them were shocked by the strange scene presented in front of them, and the end of the narrow tunnel suddenly opened up, but it was an incomparably vast underground world, at least a hundred times larger than the underground world they had passed through for the first time, and there was no end in sight, and everything in the distance was shrouded in darkness.

Ten thousand meters underground, there was a hole of such a huge scale, which completely exceeded the limits of their imagination.

They even wonder if they have come to a new world of fragments without knowing it!

The most shocking thing is that the bottom of this underground cavity is actually filled with silver liquid, and it gathers into an incomparably huge ...... Ocean!

That's right, it's the ocean!

If in the first underground world, the silver liquid converged into a lake with a diameter of 100 meters, then here, it is a vast and infinite silver ocean!

Blowing out of the darkness all around, the mighty wind made the waves on the "sea surface" surge, and a unique microclimate was formed above, condensing a pale silver, cloud-like fog mass.

But there is less than half of the creatures that are searched, whether it is a treasure or a spirit beast, or even an underground fungus, there is nothing.

10,000 meters underground. There is a rough ocean!

This kind of sight, even just thinking about it, makes people's scalps tingle!

The distress signal of the Tiger God Clan's team came from the depths of this silver sea!

Everyone glanced at each other, and despite the heavy face armor, they could still sense each other's solemn expressions.

"The psionic energy here fluctuates so strongly. A hundred times stronger than what we perceive on the ground, it should be one of the most abundant psionic places on the Bone Dragon Star! ”

"If the Bone Dragon Demon really left the Cave Mansion, it is very likely to be in the depths of this Silver Sea!"

"But you see, the silver lake just now is so small, and it has nourished lumen grass, locklock flowers, and all kinds of spirit beasts."

"This silver ocean is at least a thousand times larger than the silver lake just now, but the existence of the slightest heavenly treasure is not perceived around it!"

"There are two possibilities, either someone will take the lead and scavenge all the treasures."

"Or. In the depths of the Silver Sea, there is a powerful existence dormant that has eaten up all the heavenly treasures and spirit beasts! ”

Yan Yangtian's inference made the other five people terrified.

Captain Hong Tong said in a deep voice:

"We have no choice, even if it's not for the Tiger God Clan, we have to go down and explore, at least find out what is hidden underneath!"

"Otherwise, if the exploration team of the Blood Demon Realm opens the cave of the Bone Dragon Demon. With the ancient demon inheritance in it, the strength of the blood demon world must increase by leaps and bounds. Our Tianyuan Realm will be doomed! ”

"When we meet on a narrow road, the brave wins, we spent the resources of the whole federation to come here, not to go back with empty hands!"

"Even if there are really powerful spirit beasts in the depths of the Silver Sea, we must kill them all!"

"Vultures. It's up to you! ”

Li Yao nodded, and called up hundreds of magic weapon components from the Qiankun Ring to help everyone modify them.

Soon, the arms, legs, and backs of the six crystal armors were equipped with a large number of underwater combat kits that looked like fish fins.

Meanwhile. Yan Yangtian collected some liquid from the silver sea and conducted a preliminary analysis, confirming that it was beneficial and harmless to the human body.

A series of data about the silver liquid is fed into the crystal brains of the people.

"Let's go!"

Captain Hong Tong gave an order, and the six Star Rangers jumped into the underground silver sea together!

The density of the liquid silver is greater than that of ordinary seawater, and when it swims in it, it feels like it is swimming in the glue.

The crystal eye has almost lost its effect in the silver liquid, and can only rely on the continuous stimulation of divine thoughts and sound wave feedback to outline the topography of the "seabed".

"Wave ...... Wave...... Wave...... Wave ......"

Divine thoughts and sound wave detection systems, making monotonous sounds, map the topography of the seabed.

They dived deeper and deeper, and soon descended to less than 10,000 meters underground.

The seabed is still thousands of meters below, and the seabed landform mapped and mapped out makes everyone stunned.

Between the rolling mountains, there are large and large underwater basins, and in several of them, there are countless antique houses and pavilions, as well as huge buildings that look like ancient castles.

The tallest of them is a thousand-kilometer-tall tower.

10,000 meters underground, there is a sea!

A few kilometers under the sea, there is a city!

But I don't know if it was originally built in the depths of the earth's sea, or was it built underground, but later it was submerged by the silver sea due to changes in the earth's crust?

"The architectural style of this underground town is very characteristic of the ancient cultivation era 40,000 years ago, but it looks rough and hideous, and there are several huge buildings of unknown significance, which do not look like they are used by immortal cultivators."

"It should be the skeleton dragon demon clan, the wreckage of the secluded city."

The demon civilization is a man-made civilization, and in the early days of the Great Dark Age, it did not have its own culture and inheritance at all, so the cities built by the demon clan at the beginning were all imitations of the appearance of the cultivation realm, and even directly dismantled the mountain gates and houses of the cultivation sect and transported them to their lair.

After 30,000 years of development, the distinctive demon culture was gradually formed, and the style of various buildings, weapons and magic weapons was completely different from the cultivation realm.

Therefore, by studying the shape of the demon building, we can preliminarily determine the age of the construction of this ancient town.

"The cone giant tower in the middle, more than 1,700 meters high, with a diameter of more than 500 meters at the bottom, even if it is not the cave of the Bone Dragon Demon, it must be the core of the city!"

"Wait...... The psionic energy surging above the underwater city was chaotic, and it seemed that a fierce battle was taking place...... It's the Tiger God Sentai team! ”

Yan Yangtian positioned the position of the Tiger God team.

However, the situation of the other party seems to be very bad. The crystal armor was badly damaged, and with the mysterious silver liquid barrier, they tried several times to connect to the communication channel, but to no avail.

"Let's go up!"

There are six members of the bronze team, and the metal fins on their hands and feet swing slightly, like six dexterous sharks. Approach the underwater city.

"Wave ...... Wave...... Wave...... Bo Bo Bo Bo! ”

The feedback from the detection magic weapon became stronger and stronger, indicating that there were one or several powerful spiritual beings in front of everyone.

The spirit silk quickly outlined the appearance of these powerful beings!

There were a total of three submarine beasts, very similar to the lake bottom beasts that the Bronze Team had just encountered, each of them had hundreds of tentacles dancing wildly like snake hair, but their size was at least five times larger, and the diameter of the tentacles was more than half a meter, thicker than Li Yao's thighs!

The total length of the beast is more than 100 meters, and hundreds of tentacles grow in a huge conical carapace similar to a snail, and the carapace is full of holes. It moves by spraying and absorbing water streams.

Although the body moves slowly, the tentacles are extremely dexterous, like hundreds of sea snakes, constantly dancing and whipping, stirring the bottom of the sea.

Li Yao searched for a long time before he sensed the existence of the five Star Patrolmen of the Tiger God Clan's team in the gaps of hundreds of tentacles.

They seem to be badly wounded, and their psionic fluctuations are very weak. Struggling to the death.

"Help!"

Facing the tentacle net composed of three underwater beasts, the six members of the bronze team did not hesitate at all. Shoot away!

Li Yao faced an underwater beast on the left, and the Bloody Wind Slashing Knife conjured up a ten-meter-long sword, slashing a tentacle with one sword!

The tentacles of these submarine beasts are much tougher than the beasts in the silver lake just now, and they can't be forced at all.

Li Yao clenched the handle of the knife with both hands. With all his strength, coupled with the assistance of the crystal armor, he dragged it hard before he slashed the tentacles down and brought out a large cloud of acid. It spread into a blue mist in the sea.

But he was also swept by another tentacle, and hundreds of small holes as thin as the tip of a needle instantly appeared on the surface of the Xuan Bone Battle Armor.

The severed tentacles were not dead, but like sea snakes, twisting and twisting, stabbing at him.

Li Yao's eyebrows were raised, and his face was full of different colors:

"The tentacles of this strange beast, after leaving the body, still have the ability to attack!"

"It seems that this is the true form of the beast under the sea, the beast that lives in the silver lake, because the growth environment is too small, it is congenitally stunted!"

"Then smash all your tentacles, and see if the shards will attack!"

Li Yao gritted his teeth, and the Blood Slashing Wind Knife ignored the hindrance of the silver liquid, stirring up an unstoppable whirlpool, instantly tearing the wriggling tentacles to pieces.

Immediately after, his figure flashed, flashing dangerously through the gaps of the four tentacles, and rushed towards the body of the underwater beast.

The purple lightning blue claw conjured up five claws, mixed with the domineering and tyrannical aura of the desolate beast, and hit the carapace of the beast under the sea!

"Click!"

On the carapace of the beast under the sea, dozens of incomparably subtle cracks appeared.

But immediately from the crack seeped out a milky white liquid, like glue, and the carapace healed again!

"There is such a powerful healing ability, these underwater beasts are so powerful!"

Li Yao frowned, feeling like he didn't know where to start.

The other five members of the bronze team also fell into a bitter battle.

The attack and defense of these three undersea beasts are very powerful, and the severed tentacles can also turn into clones to attack, which cannot be destroyed in a while.

And in the depths of the Silver Sea, there are a pair of bloodthirsty eyes, watching this battle.

"A stupid cultivator, who doesn't know anything about the Bone Dragon Star, dares to venture in!"

"We in the Blood Demon Realm, but we have obtained an ancient demon inheritance that once roamed on the Bone Dragon Star, and we have studied it for three years before we dare to come here to explore and excavate!"

"It's okay, let's use the Bone Dragon Star as the grave and bury all of you, the strongest foundation building cultivators in the Tianyuan Realm, hundreds of millions of light years away!" (To be continued......)
