The soldiers of the fleet came to their senses at once, and they looked in astonishment in the direction where Khudun had fallen off the deck.

Among the small ships that were originally full of Japanese samurai standing around the warship, there was no longer a single figure left, and the small boat was empty. The soldiers saw a Japanese man with a long knife and a bloody face.

"There are assassins." On the nearest warship, one of the generals shouted.

He suddenly felt a shade around his neck, and his vision was suddenly full of blood. Behind him is a sword-wielding Japanese samurai.

Patches of samurai rushed to the deck with swords waving their swords. The soldiers of the Yuan Dynasty were horrified to find that the number of Japanese who had followed the fleet had reached such a large number, and the dense flow of people swarmed like black spots. The deck, which had been silent without a single sound, was suddenly filled with shouts and killings. The soldiers of the Yuan army struggled to resist with the weapons in their hands, and the sound of fighting and metal crashing mingled together, playing a graceful death music.

In the distance, black spherical machines slowly move towards the sea below sea level.

Nan Qiyun's group drove the submersible all the way to follow the Yuan fleet here.

In the historical records, in 1274, Kublai Khan sent Kudun to the east to invade Japan, but just a few hours ago, the Japanese shogunate fleet and the Yuan army fleet successfully completed the rendezvous.

They came to this familiar sea again, this time, more than a thousand years. What Nan Qiyun's team did not expect was that as early as more than a thousand years ago, at the sea level above the Mariana Trench, the ruins continent had already appeared in the world, and they could see clearly in the telescope, the magnificent buildings, and the dazzling golden light that emanated out of nowhere, the continent that brought fear and domination to mankind, just like this, appeared in front of their eyes again, and in the long river of history in the past. In other words, the continent moved towards the trench abyss at least once later before humans discovered the ruins continent on the ocean floor again. This kind of conscious infiltration and aggression seems to have been planned and implemented by the "black body" more than 1,000 years ago before the building was built.

Nan Qiyun saw that the fleet had stopped below the ruins continent, and in order not to affect the next move of the Yuan army and cause some unnecessary trouble, the submersible slowed down and observed the sea area in an almost stationary state.

Until the sound of chaotic fighting was heard in the distance. Nan Qiyun looked through the periscope and saw a figure falling from the deck of the ship at the front of the fleet.

The submersible approached slowly.

Kudun's wound was painful from the irritation of the sea, and he struggled desperately. Blood seeped outward, staining the waters around him red, and he looked at his fleet. The sound of fighting on the deck had gradually thinned out, and the figures of the soldiers fell on the deck, and the blood that flowed out slowly flowed down the side of the ship along the gap between the decks. The samurai stood on the deck, in a stiff and strange posture, and they held long knives with blood, and on the blades, blood dripped down the blades of the blades on their faces, and they seemed to be unaware.

Standing at the edge of the deck, their bodies slowly leaning downward.

Blood-colored waves in the sea.

When Kudun looked up again, there was no one on the deck, the golden light in the sky had completely receded, and dark clouds once again shrouded the sky, and in the blurred vision, it seemed that a large black shadow had been seen again, circling and dancing in the sky.

He felt a strange feeling of fatigue in his body, and slowly, he sank into the sea. Out of the corner of his eye, he saw a black iron ball not far away. He had never seen anything like it, and through the transparent window in the center of the iron ball, he could see the figures inside. The desire to survive began to stimulate him strongly, and he swung his whole body desperately and swam towards the iron ball.

He looked at the world in the iron ball, in that small space, four people gathered around the table, as if discussing something, behind them, was a black flat luminous object, Hu Dun did not know what it was. With all his might, he slammed the glass window, once, twice.

"Team leader, that person." Han first pointed to the figure outside the window, and could see the blood gradually spreading in the seawater.

Nan Qiyun didn't pay attention to Han Xian's words, he just glanced at Hu Dun, who was on the verge of death, and his face was expressionless.

Han Xian understood what Nan Qiyun meant, and glanced at Hu Dun sympathetically.

The violent thrashing made Kudun's fatigue even stronger, and he felt a great feeling of vertigo, and his vision blurred at a rapid pace. Excessive force caused the scrolls and maps hidden in the robes to fall out. Driven by the seawater, the two scrolled pictures were spread out and surged with the currents of the sea. Hu Dun saw Nan Qiyun's expressionless eyes, he knew that he probably wouldn't be saved, and his eyes revealed deep despair.

His hand finally hung down weakly, and his body slowly fell towards the depths of the ocean.

"Dead?" Nan Qiyun finally spoke. It's not that he doesn't want to save people, on the contrary, he sees a person die in front of his eyes, even though he has the ability, which can almost be regarded as a great torture for him. But he knew he couldn't save him. At a time when all history is moving forward according to its original trajectory, according to the assurances given to the government by the tracers before carrying out the "retrospective" plan, no member of the group shall do anything that is detrimental to the normal development of history, except at the last moment of the destruction of prehistoric civilization. If the person in front of him has carried out the act of rescuing him, then a life that should have died at this time in history will continue to live in this world against the original development trajectory of history, which will cause a serious time paradox, and every next action of this survivor, every person and everything that will be contacted, may affect or even greatly trigger a series of chain reactions to a certain extent, and the collapse of the rules of time and space may be caused by this. Since there is no theory and practice to prove the consequences of the impact on history after the retrospective stream, all actions after the retrospective flow must be taken cautiously.

Han Xian nodded.

Chu Han got up from the cab. "I've manipulated the instrument and brought the two scattered diagrams."

Wet scrolls and maps are unfolded on the table. "Xu Fu?" Chu Han was the first to recognize the Confucian scholar dressed as a scholar standing on a boat in the scroll.

In the picture, the huge palace stands in the air, and in the palace, you can see dense black shadows.

Everyone's faces are not very good-looking. The information described in this scroll means that the present time of the "black body" civilization has been pushed forward by nearly 1,500 years. From the beginning of the Qin Dynasty to the completion of the edifice system, it is very likely that prehistoric civilization began to penetrate into human society more than 2,000 years ago, and human beings did not know it. It wasn't until recently that they began to show their fangs.

They know the legend of Penglai Wonderland, but they really can't connect with the ruins in front of them, and then according to the Mariana Trench area marked on the map, it can be roughly judged that the Yuan Dynasty's action in 1274 was not to conquer Japan to the east, but to some extent reached some kind of cooperation with Japan, and jointly came to the ruins continent to find something.

"The art of immortality." Nan Qiyun blurted out. The reason why Xu Fu was able to get the strong support of Qin Shi Huang was because he wrote to the first emperor that Penglai in the East China Sea could find a cure for longevity, this kind of illusory medicine has always been the common and unremitting pursuit of the rulers of all dynasties, and the rulers of the Yuan Dynasty are likely to send such a large fleet and military force for this purpose, and do not hesitate to lower their prices to act with the island country of Kyushu.

Regarding the record of Xu Fu, he has not been heard from since his last trip to Penglai Wonderland, and there has been no record of him in the history books since then.

It's just that unexpectedly, the so-called Penglai Wonderland is actually the ruins continent that spans the sea level in front of you.

"Team leader, there's a situation above the sea." Chu Han looked at the sea outside the periscope, and then he said to Nan Qiyun.

An image of the current state of the Mariana sea level was projected above a table in the center of the submersible.

Nan Qiyun could feel the sea water around the submersible vibrating violently, and the currents constantly hitting the submersible's fuselage, making a dull sound. Above the sea, the wind gradually increased, and finally there were huge waves. Fierce winds began to rage over the sea. They saw that around the ruins continent, the black mist began to gradually spread outward, gradually covering the entire sky, and under the dancing of the wind, the sea was filled with this thick black mist.

In the sky, a black shadow in the shape of a human being, like a ghost that cannot be dispersed, floats in the air. The huge ship was whipped up by the wind and then smashed down, torn to pieces by the waves, leaving only the wreckage to sink and float on the surface. The whole world seemed to be shaken by a violent wind, and the gray-black waves crashed against everything on the sea.

Although the submersible has extremely good stability and can not be affected in such a harsh environment, Nan Qiyun can still vaguely feel the violent vibration of the outside world.

The black mist slowly dissipated, Nan Qiyun was stunned for a moment, and then he raised his head to look at the other three people.

Look at each other.

After the storm, the black gas dissipated, and the huge ruins continent suddenly disappeared into the stereoscopic image. Chu Han immediately looked towards the sea level through the periscope. In the gray-black world, the huge shadow has completely lost its original figure. A behemoth, under the cover of the storm and black mist, disappeared into this world without realizing it. Nan Qiyun did not have time to conduct further investigation of the current living site.

"You guys, do you feel like something is wrong with your eyes?" Han Xian asked.
