"That thing just turned around and almost collapsed the temple...... Fiona, do you know what that thing is?" Li Huan let out a long sigh of relief, even if he was a qi refiner, facing the undersea collapse, he was not much different from ordinary people.

"Based on what I just saw, I guess it's a sea serpent...... But master, you're now close to the Abyssal Zone, a place that has barely been explored by humans. Fiona said with a serious face: "The terrifying legends about the ocean in the world are almost all from the monsters of the abyssal zone. ”

"Well, I have the feeling that it must be some kind of sea serpent...... There are no monsters in this world. Li Huan groaned.

Sea snakes, although they look like moray eels, are not the same species at all. The thing called "sea snake" in the West is actually the same as the "dragon" said by the Easterners, it is a kind of sea creature, and the dragon is just a creature that exists in fantasy.

The sea serpent is a sea monster with a snake-like body that has been sighted for thousands of years. Sea snakes are usually sighted on boats or on the shore, and sometimes scientists. Although there are many sightings, there are still no clear records to prove their existence, but there is some evidence to be believed.

In 1845, the story of a huge skeleton found in the Citi Nation of Alabama was later put together into a complete skeleton. The skeleton is a 114-foot-long snake skeleton that was exhibited in New York and Europe, but was unfortunately destroyed in the Great Chicago Fire of 1871.

On October 11, 1848, the British ship "Daydalas" returned to Plymouth Harbour from the East Indies, and the ship submitted a report. According to the report, at 5 p.m. on 6 August, when the ship was about 300 miles from Africa in the South Atlantic, Lieutenant Officer Sartoles saw a very strange object swimming towards the warship from the rear. Sartoles immediately reported to his superiors. The captain, two officers, and others rushed to see a large serpent swimming in front of the ship. Witnesses estimated that the sea serpent was 60 feet long and about 15 or 6 inches in diameter as its head and neck as it swam southwest over the "Dedalas" at a speed of more than 10 miles per hour. Captain McQuay said it passed "very close to the side below the stern."

On November 30, 1875, the Illustrated London News reported that the Royal Navy coal carrier Pauline was sailing to the coast of Brazil when it encountered a battle between a sea snake and a sperm whale. According to Captain Dreva "The snake body wrapped around the sperm whale for about two weeks......"

Let's just think it's a sea snake for the time being, it's gone anyway, and it doesn't matter what it is.

Soon, the aftermath caused by the collapse of the temple also stopped, and Li Huan was much more careful this time, putting away the "luminous pearl" and groping under the water completely with the infrared night vision function. Just after the collapse, a large hole was opened in the ceiling, and a lot of things fell from it.

Li Huan used his spiritual power to explore, and it turned out to be a large number of shipwrecks that had become wreckage!

The wrecks are very old, ranging from wooden hull wreckage to rusty metal wreckage. The wreckage is supposed to be silent above the ceiling of the temple, and almost all the places that can rot are gone.

After a catastrophic collapse, the temple had lost its original appearance except for the statue that was still intact. Li Huan looked around and found no useful clues. And Li Huan felt that he should leave here quickly, as soon as the collapsed ceiling and stone pillars were stacked together, everything was buried, and there was nothing else here except a god statue. Second, no one can say who here will not collapse for the second time After a big landslide, Li Huan could feel that the eyes watching him around were gone, and it seemed that even the sea beasts in the sea knew that there was danger here.

But there was no way out of the temple.

Li Huan now has two choices.

Either go back the way you came, or walk out of the place where the collapse overhead. But it was not easy to find the underwater ancient city, and he left without finding anything, which is a bit too inconsistent with Li Huan's character. He was thinking about it when he suddenly heard a "quack" sound not far away, as if something was breaking.

Li Huan followed the sound to find it, only to see that there was a collapse on the ground. Probably just now the ceiling and stone pillars smashed on the ground, the ground could not support this weight and collapsed as a whole, and the collapsed ground actually revealed a blue and faint hole!

"Oh no! This is undersea lava gas!" Li Huan hurriedly stepped back.

Almost instantly, the originally pitch-black seabed turned into a dark blue, blue blinding. The blue flames that erupted from the hole burned in the water, and as the bubbles rolled, they seemed to expel all the darkness. At first, the blue flames were just as tall as a person, and in less than half a minute, the entire temple was filled with blue flames.

What emerges from the hole is not only the flames, but also the continuous bubbles, which come in different shapes and sizes, but as soon as they are caught up by the open flames, they will explode immediately, and then ignite more bubbles. The underwater world, which was originally pitch black, became bright because of the blue fire, and large clouds of blue flames floated in the seawater, some fell on the coral jungle, some fell on the wreckage of the ship's hull, as if several searchlights were turned on at the same time, illuminating the surroundings thoroughly.

A fire broke out in the sea, and it was an apocalyptic sight.

"Master, hurry up!"

"Brother Huan, run, the fire is getting bigger and bigger!"

Seeing the lava gas gushing from the bottom of the sea, almost burning the entire seawater, the two girls on the virtual screen shouted anxiously.

"Unlucky!How can there be lava gas here!" Li Huan cursed, and quickly swam towards the place where the ceiling of the temple had collapsed. I thought it was an underground secret passage, but I didn't know it was a drop-in entrance. The blue flames that kept gushing out of the entrance of the cave engulfed everything, and the temperature of the sea began to rise rapidly, and under the light of the blue flames, Li Huan saw that the fish in the temple began to flee desperately. The one who escaped slowly was swept into the blue fire, and was instantly roasted to the point that his whole body turned white, and those who were lucky enough to run away at the first time were also scalded into a strange shape.

The entire temple was suddenly shrouded in the shadow of death due to the eruption of lava gas.

Lava gas can be seen as a variant of natural gas.

Along with volcanic activity, in addition to magma, the most dangerous gases are the volcanoes. When the lava melts, all kinds of heavy metals or flammable gases are filtered out and stored in the magma pipeline, and as soon as the pipeline is opened, these gases will immediately gush out. Because they have been scorched by magma for a lot of years, these gases are extremely hot, toxic, and flammable. Lava can be dodged, but poisonous gases can't.

Beneath this lost city, there must be an extremely active undersea volcano, and just by looking at the momentum of the lava gas eruption, you can know how the city was tortured back then.

It was also the first time Li Huan had seen this terrifying flame, and he left the vent with his hands and feet, swimming out of the crack in the ceiling, trying to stay away from the lava gas. However, although this gas is very terrible, not only flammable but also extremely toxic, it is always a "pent-up" excess gas in the magma pipeline, not a whole natural gas vein, and the eruption will not take long.

Sure enough, within five minutes, the blue flames began to dim and eventually turned to pitch black. Once again, the bottom of the ocean has reverted to a state of darkness, with only the slightly warm currents proving that it was once infused by flames.

"Okay, the lava gas should be drained...... I'll go down and see first. Li Huan breathed a long sigh of relief.

The huge statue of Poseidon, the underwater volcano beneath the city, these discoveries have brought this underwater ancient city closer and closer to Atlantis.

Because of the eruption and burning of lava gas just now, the creatures in the temple have been cleared, and Li Huan can take out the "luminous bead" to illuminate it. The temple was ravaged by the flames, littered with dead fish and grilled shellfish, and the smell of cooked seafood even filled the water. Fish and other sea creatures with bad luck float in the water, giving them an eerie feeling.

Li Huan carefully swam to the place where the lava gas came out again, at this time the bright blue was already prunes, and then there was a faint orange-red light in the depths of the cave, and he could feel a stream of heat, gushing out a volcanic pipe in the cave, there was no doubt. Volcanoes are much more active on the ocean floor than on land, and since they are volcanic pipes, and they are active volcanic pipes, there must be nothing in them.

After Li Huan found out the outside of the pipeline, he planned to leave.

As soon as he turned over and swam two steps, he felt a strong flow of water pulling him, Li Huan looked back, and sure enough, a water whirlpool mixed with mud and sand appeared outside the entrance of the cave, which was spinning at high speed, and Li Huan was led by this force to involuntarily retreat towards the mouth of the volcanic pipeline. He was so shocked that he detonated several spirit balloons in a row, but this force was so great that he couldn't resist it at all.

"Damn! The pipeline broke through the underground cavity, is it all the unlucky things I have to encounter again!" Li Huan scolded: "It doesn't matter if you encounter a lava gas eruption, how can you still encounter an underground cavity!"

The so-called underground cavities are the cavities left behind by lava eruptions.

Once the pipes are opened, the gas in the pipes erupts and seawater fills the caves. Such cavities vary in size, and the seafloor and volcanoes have been active for hundreds of millions of years, so it is not surprising that there is even a cavity of hundreds of square kilometers underground. Think of the goaf oil fields in Saudi Arabia that keep collapsing because the oil is drained and huge cavities are created in the ground. However, this is at the bottom of the sea, and the cavity will not collapse, but it must be filled with seawater to calm down.

This is also the reason why there are often strange whirlpools on the surface of the sea, sometimes the earthquake on the bottom of the sea cracks, and a huge amount of seawater rushes into the cavity, causing huge whirlpools on the sea surface.

If Li Huan was on the surface of the sea, the power of the whirlpool was not worth mentioning.

But he is now at the drain four hundred meters under the water of the drain.

Nearly fifty atmospheres of pressure pulled him towards the entrance of the cave, tens of billions of tons of seawater were pouring into the hole at an alarming speed, Li Huan was able to swim no matter how much he could swim, but under the condition of the whirlpool, he couldn't use his skills at all. The intense pressure from the depths of the passage made the whirlpool stronger and stronger. With his own strength alone, even a Qi Refiner would not have the slightest ability to resist before the influx of tens of billions of tons of seawater.

It doesn't matter if he is sucked in, anyway, Li Huan is not short of oxygen, so it's a big deal to wait for the underground cavity to fill up and slowly swim out. But the problem is that the dark red color inside this sea cave indicates that there is still uncooled magma in the cave!
