While scientists and the public were speculating about Drow Venus and the ancient Sahara, Lu Yuan had once again come to the Atlantic.

After Lu Yuan left the Sahara, he returned to Yingzhou with metal plates.

In the days when he returned to Yingzhou, Lu Yuan spent the rest of his time studying metal plates, except for going to the ward to accompany Sun Jia on time every day.

After half a month of research, Lu Yuan finally confirmed that the map on the metal plate is the North Atlantic region today.

The city shown on the map is likely to be the main city of Atlantis, Poseidonia.

After confirming the information on the metal plate, Lu Yuan did not set off immediately, but made sufficient preparations first.

This time, he was going to the Atlantic Ocean, where the average depth was close to 4,000 meters.

Without the right equipment, it is up to him to complete the exploration.

After Lu Yuan's research, he quickly sent out procurement information like major related enterprises in the world.

After three months of waiting, when all the required equipment was in place, Lu Yuan went to the western country closest to his destination.

After staying in the West for less than a day, Lu Yuan sailed into the Atlantic Ocean alone.

After three days of sailing, Lu Yuan finally reached the target sea area.

Had lunch on the sea and rested for another half hour.

Lu Yuan entered the ocean for the first time, and the temperature of the sea water was still relatively low this season.

However, this did not bother Lu Yuan.

He dived to the bottom of the sea as fast as he could, and when he reached 1,500 meters below the surface, the life in the ocean began to decline dramatically.

Just when Lu Yuan felt that everything was going well, a feeling of palpitations suddenly rose in his heart.

This was a very dangerous feeling, and Lu Yuan hadn't felt it in many years.

The last time I encountered this feeling was in the submarine pit southeast of Yingzhou.

Lu Yuan felt as if he was being targeted by something.

He instantly raised his vigilance, and in order to ensure safety, he also took out the Yao Light Sword and the spear that he renamed the Black Dragon Lance at the same time.

He slung the spear on his back, holding the Yaoguang Sword in his hand.

After getting ready, he let go of his divine sense with all his strength and continued to move towards the bottom of the sea.

Now Lu Yuan's divine consciousness can be released 1,500 meters away.

Only creatures that are 1,500 meters within his perimeter will not be able to evade his detection.

Lu Yuan continued to dive, and the sense of crisis in his heart became stronger and stronger.

He knew in his heart that danger was getting closer and closer to him.

If it was before Sun Jia's accident, Lu Yuan would have chosen to retreat long ago.

But this time he didn't flinch, he knew that if he really wanted to save Sun Jia, he needed to at least reach the cultivation of the Jindan stage.

If you want to break through the Jindan period, you need a lot of energy, and it is definitely impossible with the current external energy of the earth.

His only hope now is to find all kinds of treasures left over from the major ruins of ancient times, and let himself break through the foundation building period first.

Then find a way to go to other planets to get more energy.

The Atlanteans are a very developed energy civilization, and if they can find their main city, Lu Yuan believes that they will definitely be able to obtain some magnetos containing energy.

Although the energy in most magnetites cannot be directly absorbed, it is also good as an energy source for one's own interstellar voyages in the future.

Therefore, it is impossible for Lu Yuan to retreat, and Lu Yuan is also very confident in his own strength, he believes that even if he can't beat him, it should still be possible to save his life.

With such a mood, Lu Yuan approached the bottom of the sea step by step.

More than ten minutes later, a huge monster appeared in Lu Yuan's divine sense.

"North Sea Monster!"

The first thing that jumped into Lu Yuan's mind was this word.

What appeared in Lu Yuan's consciousness was a huge octopus.

At the same time that Lu Yuan discovered it, it also discovered Lu Yuan.

One person and one monster confronted each other like this, and both sides felt a great danger in each other's body, so neither side dared to act rashly.

Taking advantage of the confrontation, Lu Yuan also began to observe the huge octopus in front of him.

The octopus is at least 150 meters long, and it has eight huge tentacles.

It has huge compound eyes on its head, and two rows of huge suction cups on each tentacle.

Lu Yuan stared at the octopus's suction cup, and felt a tingling on his body.

Octopuses often have suction cups that are more than 5, 10 or even 20 times their body weight.

Lu Yuan swallowed his saliva, judging from the weight of the octopus in front of him, the power of his sucker must be amazing.

Although his body is very strong, it is not certain whether he can resist the gravity of its sucker.

At this time, Lu Yuan also thought of the scientists' research on octopuses.

Some scientists have studied that octopuses have two brains.

It is also the most intelligent creature on the planet, and its intelligence is definitely above that of humans.

If it weren't for the fact that the lifespan of an octopus is too short (the lifespan of an octopus is generally only three years), it would be the octopus that rules the earth.

"This octopus in front of me is not easy to deal with. ”

Lu Yuan was thinking about how to deal with the octopus fish in front of him.

The octopus in front of him quickly mimicked the form of a sea snake.

When Lu Yuan was feeling strange, the octopus monster that mimicked the sea snake had already launched an attack on Lu Yuan.

"Oops!"

Lu Yuan was shocked in his heart, and quickly dodged to the side, and at the same time, the remote light sword in his hand also launched a counterattack.

"Bump"!

After all, it was a battle under the sea, and Lu Yuan was definitely inferior to the octopus monster in terms of flexibility.

In the first encounter, Lu Yuan suffered a big loss and was hit by the octopus monster.

And his counterattack didn't hit the octopus monster at all.

Lu Yuan's heart sank, he knew that today's battle was not easy to fight.

Fighting at the bottom of the sea, the flexibility of one's body is obviously not as good as that of an octopus.

However, he was not too worried, although his body was not as flexible as an octopus, he was not slow to escape.

If you can't do it, you can still choose to escape, of course, this is the last forced choice.

Now I don't have to fail, my remote lightsaren is an energy weapon, not a vegetarian.

Lu Yuan believed that if he was attacked by his own remote light sword, the octopus monster would also be unbearable.

After the second brief confrontation between Lu Yuan and the octopus monster, a fierce battle broke out again.

This time the two sides are no longer tentative.

This time, the two sides fought for more than an hour.

The battle between the two alarmed all the creatures of the surrounding sea.

Received the image of the battle, and the surrounding sea creatures fled.

During the battle, Lu Yuan was hit by the octopus monster at least ten times.

The same Yao Light Sword in Lu Yuan's hand also gave the octopus monster two ruthless blows.

Since it was the second time, the octopus monster actually sucked Lu Yuan with its tentacles and wanted to suck Lu Yuan to death.

Lu Yuan just took advantage of this opportunity to cut off half of the octopus monster's tentacles with one sword.
