The more underground, the more tortuous and rugged the tunnel is. Many places are blocked by collapses. The tiger god team has just made a hole for one person to pass through. It has to use both hands and feet to get through.

In the endless darkness, occasionally from the tiny gap beside the tunnel, the weak light of the underground crystal leaked out, just like the slender eyes inlaid on the wall of the tunnel, staring at these explorers without blinking.

Li Yao's six people were moving around the cave wall at a very fast speed. Half an hour later, they arrived at 9500 meters underground!

Despite all the psychological preparation, the strange scene in front of them surprised all of them. The narrow end of the tunnel suddenly opened up, but it was a vast underground world, which was at least 100 times larger than the underground world they passed through for the first time. They couldn't see the end at a glance, and everything in the distance was shrouded in darkness.

Ten thousand meters below the ground, there is such a huge void, which is beyond the limit of their imagination.

They even doubt whether they have come to a new world of debris without being aware of it!

The most shocking thing is that this underground cavity is filled with silver liquid at the bottom, and converges into a huge ocean!

Yes, the ocean!

If we say that in the first underground world, silver liquid converged into a lake with a diameter of 100 meters, then here is the vast Silver Ocean!

Blowing out from the darkness around, the mighty strong wind makes the waves on the "sea surface" surge, and a unique microclimate is formed above, condensing a light silver cloud like fog.

But we can't find any living creatures, no matter they are natural materials, local treasures, spirit beasts, or even underground fungi.

Ten thousand meters under the ground, there is a rough sea!

This kind of scene, even if just think about it, makes people feel numb!

The call for help signal of the tiger team came from the depths of this silver sea!

They all looked at each other. Although they were separated by heavy armor, they could still feel each other's dignified expressions.

"The psionic wave here is so strong that it is 100 times stronger than what we perceive on the ground. It should be one of the most abundant psionic places on skeletal dragon!"

"If the skeleton dragon devil really left the cave, it is very likely that it is in the depths of this silver sea!"

"But you see, just now that Silver Lake is so small, it nourishes all kinds of animals, such as luminescent grass, Cynanchum and so on."

"This silver ocean is at least a thousand times larger than the silver lake just now, but there is no sense of the existence of any natural resources and local treasures around it!"

"There are two possibilities, or someone will be the first step, the natural resources and land treasures are searched clean."

"Or, in the depths of the silver sea, there is some powerful existence dormant, which has eaten up all the natural resources, land treasures and spirit beasts!"

Yan Yangtian's inference made the other five people's hair stand on end.

Captain Hong Tong said in a deep voice:

"We have no choice, even if not for the tiger team, we must go down to explore, at least to find out what is hidden below!"

"Otherwise, if the exploration team of the blood demon world opens the cave of the skeleton dragon demon and gets the inheritance of the ancient demon, the strength of the blood demon world will advance by leaps and bounds, and our Tianyuan world will be doomed!"

"If we meet in a narrow road, the brave will win. We spend the resources of the whole Federation to come here, not to go back empty handed."

"Even if there are powerful spirit beasts in the depths of the silver sea, we should kill them all!"

"Vulture, it's up to you!"

Li Yao nodded, and hundreds of magic weapon components were transferred from the Qian Kun ring to help people to refit.

Soon, the arms, legs and back of Liutai crystal armor were equipped with a large number of underwater combat kits that looked like fins.

At the same time, yanyangtian collected some liquid from Yinhai and made preliminary analysis, which confirmed that it was beneficial and harmless to human body.

A series of data about the silver liquid are input into the crystal brain of people.

"Let's go!"

At the command of Captain Hong Tong, six star patrollers jump into the sea of silver!

The density of liquid silver is higher than that of ordinary sea water. When you swim in it, you feel like you're stuck in the glue.

The crystal eye almost lost its function in the silver liquid, so it can only rely on the continuous stimulation of the mind and the feedback of the sound wave to outline the topography of the "seabed".

"Bo... Bo... Bo... Bo..."

The shennian and sonic wave detection systems make monotonous noises and map out the seabed topography.

They dived deeper and deeper, and soon fell to 10000 meters below the ground.

The bottom of the sea is still thousands of meters below, and the topography of the bottom of the sea, which has been mapped out, has stunned people.

Between the rolling mountains, there are a large number of submarine basins. In several basins, there are countless ancient houses and pavilions, as well as huge buildings that look like ancient castles.

One of the tallest buildings is more than 1000 meters high, just like a conical tower.

Ten thousand meters underground, there is a sea!

Thousands of meters under the sea, there is a city!

But I don't know whether it was originally built in the depths of the earth sea or underground, but later it was submerged by the silver sea due to crustal movement?

"The architectural style of this underground town is very similar to that of the ancient repair time 40000 years ago, but it is rough and ferocious. There are also several huge buildings of unknown significance, which do not seem to be used by the immortals."

"It should be the remains of the city where the Dragon demons live in seclusion."

The demon civilization is a kind of artificial civilization. At the beginning of the great dark age, there was no culture and inheritance of its own. Therefore, the cities built by the demon clan at first imitated the appearance of the cultivation world, and even directly demolished the mountain gates and houses of the cultivation sects and transported them to their nests.

After 30000 years of development, it gradually formed a distinctive demon culture. The styles of all kinds of architecture, weapons and magic weapons are quite different from those of Xiuzhen.

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

"The huge conical tower in the middle is more than 1700 meters high, with a diameter of more than 500 meters at the bottom. Even if it is not the cave of dragon demon, it must be the core of the city!"

"Wait... The power surge above the undersea city is very chaotic. It seems that a fierce battle is taking place... It's the tiger team!"

Yan Yangtian locates the position of the tiger god team.

However, the situation of the other side seems to be very bad. The crystal armor is seriously damaged. Coupled with the barrier of mysterious silver liquid, they tried to connect to the communication channel several times without success.

"Let's go up!"

Bronze team six people, the metal fins on the hands and feet gently swing, like six dexterous sharks, close to the undersea city.

"Wave... Wave... Wave... Wave... Wave!"

The feedback from the detection magic weapon is more and more intense, indicating that there is one or several powerful powers in front of people.

Lingsi quickly outlines the appearance of these powerful beings!

There are three underwater monsters, which are very similar to the one that the bronze team just met. Each of them has hundreds of tentacles dancing like snake hair, but they are at least five times larger. The diameter of the tentacles is more than half a meter, which is thicker than Li Yao's thighs!

The total length of the sea floor beast is more than 100 meters. Hundreds of tentacles grow in a huge conical shell similar to Oncomelania hupensis. The shell is full of holes and moves by spraying and absorbing water.

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

After searching for a long time, Li Yao sensed the existence of the five star Scouts of the tiger god team in the gaps of hundreds of tentacles.

They seem to be seriously injured, their power fluctuations are very weak, and they are struggling.

"Help

In the face of the tentacle net composed of three different animals on the sea floor, the six members of the bronze team did not hesitate, but shot away!

Facing a sea monster on the left, Li Yao's blood chopping wind knife turned into a ten meter long sword awn, and hit a tentacle with one knife!

The tentacles of these animals on the sea floor are much stronger than those in the silver lake just now. They can't bear any force at all.

Li Yao clenched the handle with both hands and exerted all his strength. With the help of crystal armor, he cut off his tentacles and brought out a large amount of acid, which spread into a green fog in the sea.

But he was swept by another tentacle, and hundreds of pinprick like holes appeared on the surface of Xuangu battle armor.

The severed tentacle, however, was not dead. On the contrary, like a sea snake, it twisted and stabbed at him.

Li Yao's eyebrows raised and his face changed

"This beast's tentacle, after leaving its body, still has the ability to attack!"

"It seems that this is the real form of the sea bottom beast. The beast that lives in the Silver Lake, because the growth environment is too small, congenital dysplasia!"

"Then grind up all your tentacles to see if the fragments will attack you."

Li Yao clenched his teeth. Ignoring the obstruction of silver liquid, he stirred up an irresistible whirlpool and instantly tore the wriggling tentacle to pieces.

Then, with a flash of his body, he flashed through the cracks of the four tentacles and rushed to the bottom of the sea.

The purple electric green dark claw is transformed into five claw awns, mixed with the atmosphere of tyranny and tyranny of wild beasts. It's in the middle of the shell of a strange beast on the sea floor!

"Click!"

There are dozens of tiny cracks on the crustacean of the sea floor beast.

But from the cracks immediately penetrated out of a milky liquid, like glue in general, so that the shell healed again!

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

Li Yao frowned, feeling that he couldn't start.

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

The attack power and defense power of these three beasts are very strong, and the severed tentacles can be turned into separate attacks, which can't be eliminated for a while.

And in the depths of the silver sea, there are a pair of bloodthirsty eyes, are paying attention to the battle.

"Stupid cultivator, who knows nothing about the Dragon Star, dares to venture in!"

"Our blood demon world, however, has been inherited by an ancient demon who once wandered on the skeleton Dragon Star. We have studied it for three years before we dare to explore and explore here!"

"Well, take the skeleton Dragon Star as the tomb and bury you, the most powerful foundation building monks in the Tianyuan Kingdom, hundreds of millions of light years away."
