A day later, the star shines on the Federation, above the East China Sea, 1300 kilometers from the eastern coastline.

Although most of the territory of the Federation is built on the "Tianyuan continent", there are many pearl like islands scattered in the vast sea area to the east of the continent.

These islands are surrounded by the rich resources of the ocean, and they are also valuable relics left by the East polar countries.

There are towns on many islands. Even among the largest islands, there is a big sea city with a population of more than 1.5 million.

Therefore, there are countless flights every day, carrying countless people and materials in spar boats, between the mainland and the islands.

At the moment, a crystal floating boat from Tiandu city is like a turtle with wings, swimming in the sky.

At the end of the sea and sky, there are dark clouds, lightning and thunder, and the super storm "cuckoo" is rushing across the ocean, setting off huge waves.

In the depths of the ocean, the undercurrent is surging, and an active submarine volcano wakes up completely, bombarding the hottest and most violent forces in the depths of the earth. With the change of the earth's crust, the volcanic eruption converges into a devastating tsunami!

In order to avoid natural disasters, the spar lowered its altitude and accelerated its speed, trying to reach its destination before the storm and tsunami hit.

At this time, from the bottom of the spar floating boat, between the crevices of the landing gear, a group of "things" fell down and fell to the sea.

The power surge brought by the natural disaster hit the surrounding waters one step earlier than the tsunami and storm. The monitoring magic weapons on the spar boat were disturbed, and they did not notice the small "foreign matter" falling.

"Wow!"

This group of "things" fell into the choppy ocean, without even a little spray, it was swallowed by the sea and sank straight to the bottom of the sea.

Lee has successfully dived into the ocean.

"Shua!"

Almost to the bottom of the sea, he extracted the Xuangu battle armor blood demon type. After the completion of colonization, he started the crystal brain and scanned the bottom of the sea.

"Bo! Bo! Wave

On top of the light curtain, the topographic map of the sea floor gradually became clear, and a slightly flashing spirit vein wreck appeared in the corner of the light curtain.

Li Yao also extracted dozens of small beads from the Qiankun ring. As soon as he let go, small beads filled with gas came out of the sea one after another.

This is a weather buoy used to capture meteorological data and analyze the intensity of tsunamis and storms.

After releasing seven or eight beads, Lee started the underwater propulsion unit he had just added. It was like a big fish shuttling between the undercurrents.

Soon, he found the remains of a huge vein.

It is the remains of the "Ti Mn nodule vein" discovered 100 years ago as shown in the data given to him by Professor Mo Xuan.

The drained vein, hundreds of kilometers long, is like a hollowed out dragon, quietly lying between the folds of the sea floor.

Li Yao dived into the vein, traced back to the source, swam all the way and released the weather float. An hour later, he found the undersea mining base at the end of the vein.

This mining base, as a whole, is radioactive, just like a giant crab, which is a huge undersea city.

There is also a pipeline for refining super tough metals to the sea, and there is a huge floating platform above the sea.

Li Yao sensed a very strong power fluctuation. Many underwater special crystal warships and elite armored division with powerful power fluctuation were active nearby.

The large-scale air circulation array, which absorbs oxygen from the sea and replenishes fresh air inside, is also surging with strong psionic fluctuations. In Li Yao's crystal brain, it makes a "hissing" sound and runs to the limit.

After a careful observation, Li Yao found that around the undersea mining base, at least hundreds of Armored Divisions and seven or eight crystal warships were building "undersea psionic anti Botti".

Although the tsunami and storm have little impact on the seabed, they are still meticulously carrying out safety operations. It can be seen that this base is very important to them and can not be ignored.

That's right.

This undersea mining base belonging to the "Qinglei faction" has been sealed up for decades. However, during these decades, the undersea mining technology of the Federation has not made great progress. Simply from the perspective of operation, there is still no mining value here.

What is the force that makes this undersea mining base operate again and protect it so tightly?

Lying in a dark trench, Li Yaozhe emitted an extremely weak dark light, scanning all the details of the seabed mining base, including the weakest link.

Half an hour later, he collected all the data, turned and left, sped up and swam to a place 300 kilometers away, which had been calculated for a long time.

"Broken vein trench, with a depth of more than 55700 meters, is the third largest trench in terms of the depth of tianyuanxing discovered by the Federation so far."

Li Yao floats above the broken vein trench, quietly overlooking the magnificent scene below.

The broken vein trench is like a dark abyss. Even when the surrounding sea water comes here, it will continue to fall, forming an incredible scene like "underwater waterfall".

Even Li Yao's mind swayed for a moment, giving birth to a kind of indescribable shivering feeling that he would be sucked into the earth's core by the trench.

The deep sea, do not know how many secrets hidden, and how many dormant people everywhere cold, scared beast!

Taking a deep breath, Li Yao extracted a bright yellow colloid from the Qiankun ring, crushed it with his psionic power, turned it into a ball of powder, and scattered it into the abyss of the sea.

This is the fish swim bladder essence of the golden spirit purple scale fish, some kind of bottom sea animal's favorite.

Lee waited patiently.

Ten minutes later, something came from the abyss.

First of all, a colorful streamer roared out, and groups of almost transparent, beautiful fish, each with only the length of Li Yao's fingers, but the fish's mouth turned into a thorn. Instead of attacking him, they ran up in panic!

Then, a pair of small blood red eyes appeared. Their owners were "deep sea thorn sharks" with thorns and spiral teeth in their mouths. They were one of the most dangerous hunters in the tianyuanxing ocean. When they were hungry, they even hunted other sharks at will, so they had another nickname, the "fierce shark"!

However, these "ferocious sharks" are also like frightened rabbits, passing by Li Yao, ignoring him and the small fish in front of him and rushing away.

"Boom! Boom! Boom

There was a roar from the abyss of the sea. The sound wave penetrated the heavy sea water and Lee's crystal armor and exploded in his cochlea like a crystal bomb.

Clumps of muddy water, like thick smoke, erupted from the abyss.

Then, a whale, more than 300 meters long and covered with gray folds, darted out of the abyss!

It's like a small crystal warship. Its head is covered with solid bone armor. Its mouth is wide open and its tusks are covered with hairy tentacles. For most of its prey, including the "fierce shark", it doesn't need to chew at all. It can be inhaled directly with the sea water!

Even Li Yao, when facing this huge iron armored baleen whale, can't help but feel a little frightened.

However——

"Shua!"

Before the giant baleen whale could swim out of the abyss, it was caught up by a very strong, dragon like tentacle and rolled up!

The diameter of this tentacle is more than three meters, and it is covered with suction cups. Around the suction cup, there are rings of protrusions similar to sharp teeth and blade. They wrap around the body of the baleen whale, deeply embedded in flesh and blood. No matter how hard the baleen whale struggles, it can't break free!

"Click!"

When the tentacles were tightened, cracks appeared on the hard bones of the baleen whales. Thousands of suckers squirmed at the same time, releasing corrosive acid, melting the flesh and blood of the baleen whales, inhaling the tentacles and sending them down the abyss!

The armored fin whale is in agony, struggling at the edge of the trench. The hardest rock on the bottom of the sea is smashed by it, but it is useless.

Behind it, in the abyss, new tentacles came out, like seven or eight hungry poisonous dragons, holding their heads high and staring at their prey.

A moment later, they drew a perfect arc back, like a full bow, and pulled it hard.

"Bang! Bang! Bang

With each stroke, a large piece of flesh and blood can be torn from the baleen whale. Soon, the struggling strength of the baleen whale gradually weakened, and it was entangled by these tentacles and dragged back to the abyss.

"Chi Liu, Chi Liu! Chuckling, chuckling

In the abyss, there was the sound of swallowing, which made the scalp numb, and occasionally there was the sound of bone fragmentation.

When Li Yao swam over the abyss, he only saw that in the dark, the skeleton of the armored baleen whale was dragged into the trench by something.

Li Yao licked his lips, extracted a triple six barrel rotary bombardment gun, and fired it towards the depth of baleen whale skeleton!

"Boom boom boom boom!"

The underwater special psionic explosive burst out a series of flashes in the abyss, which also stimulated an earth shaking roar.

"Roar!"

For a moment, the earth was shaking and the undercurrent was surging. It seemed that there was a volcanic eruption in the abyss, and a new undersea mountain was rising!

Seven or eight tentacles shot out like cannonballs, almost hitting Li Yao. Then, a huge object of five or six hundred meters floated from the trench!

It's like a towering hill. There are no eyes on the balloon like brain bag, but it's full of folds, each of which is covered with serrated tusks. At the top of the head, it's like an organ like a sea anemone, with fluorescent tentacles swaying wildly and colorful lights changing!

The huge body is supported by nine stout tentacles. There are dozens of jet holes under the body, which can help it adjust its angle accurately, jet forward quickly, and stimulate the speed and agility that are not consistent with the huge body!

This is the most terrible beast in the ocean of Tianyuan star, the abyss Troll!
