Nan Qiyun woke up three hours earlier than the action time. At five o'clock in the morning, the sun had not yet risen, but the sky was already a little white. The light of the moon had gradually thinned, and in the distance, a bright star could be seen shining in the sky, which was particularly dazzling, and Nan Qiyun knew that it was the morning star.

Hundreds of miniature submersibles assembled last night were lined up on the beach, and quite a few members of the detachment had already woken up from their sleep.

At about seven o'clock, a detachment of 1,000 people set out for the deep sea level of the trench in the waters of the Mariana Islands. According to the information obtained by Nan Qiyun, the explorer Chen Tian was launched at about ten o'clock in the morning, and the plan of the thousand-man detachment was two hours earlier than the plan.

The sea was calm, and the deepest dive in the ocean had never exceeded 15,000 kilometers before Chen broke the record. In the current understanding of mankind, 15,000 meters seems to be the limit of the depth of the ocean.

Once the geographical coordinates are confirmed, the plan begins. Hundreds of submersibles are dispersed to the bottom of the seabed in a sea area of one square kilometer according to the predetermined plan, because the passage of the abyss on the bottom of the sea is too narrow, so hundreds of submersibles need a certain amount of time to pass through in turn, according to Nan Qiyun's calculation in advance, it takes about an hour or so for all submersibles to pass through the channel, so that after passing through the channel, there can be more than an hour to prepare in all aspects.

This is the first time in Nan Qiyun's life that he has taken a submersible. In the vast sea, the light emitted by hundreds of submersibles is like twinkling stars in the dark night, cruising down in this darkness.

The beauty of nature lies in its eternal unknowability and endless explorability. It is precisely because human beings can never fully understand and grasp the mysteries of nature that they continue to move forward.

Silence pervades every molecule in this air, and Nan Qiyun can't help but have a deep admiration for the first warrior who bravely explored this deep sea to break the limits of human beings. At that time, he alone accomplished what can be called the greatest discovery in the history of mankind. Now that hundreds of submersibles are sinking together, he feels such a strong sense of loneliness in this extremely quiet space, but Chen Tian has resisted this feeling.

The probe detected a large area of architectural ruins below.

"Arriving at the destination, all the machines disperse and assemble in the sea above Hall 108." Nan Qiyun said to all the team members through the communicator.

"Note, turn on the mental anti-interference device, isolate the visual illusion of the palace ruins, repeat, turn on the mental anti-interference device. Everyone is on alert. Nan Qiyun added, in the previous site exploration operation, the other team members were damaged in the hallucinatory reflection of the ruins, and they almost died here, after the ruins continent appeared, it showed the great power of the prehistoric civilization ruins, which must be guarded against. For each of them, there is a lesson from the past, and there can be no second mistake.

At 10:30 a.m., all the members of the detachment assembled in the planned sea area. Nan Qiyun looked at the time, if there was no error in the estimation of the time, Chen Tian's diving operation would have passed about thirty minutes. Out of the protection of the historical trajectory, this plan, except for the last link to erase the existence of the "black body", all the rest of the actions must be implemented on the basis of not affecting the original development process of history, the task of the thousand-person detachment now is to wait quietly, for the world in this time and space, they must face what will happen next as a spectator.

An hour later, a small green dot of light appeared on the detector. The depth reading is now 30000.000 meters.

"He's coming." Han Xian said.

"Everybody pay attention to the target." Chu Han looked out the submersible observation window. He could already faintly see the light of the submersible reflected in the sea above.

The distance is getting closer. The members of the detachment could clearly see the figure of the submersible piloted by Chen Tian. This is a spherical smooth-bore submersible, and the body of the ball has been slightly deformed due to the strong water pressure, giving it an ellipsoidal shape. Through the pressure-resistant glass of the submersible, a small square table can be seen in the submersible, and a tall figure sits next to it, holding a wine glass that sways with wine in his hand. The sea area was pitch black, and the members of the detachment had turned on the anti-detection function when they were riding submersibles, so Chen Tian did not find the hundreds of submersibles near him. He quietly dived towards the ruins of a prehistoric civilization. He will soon arrive at the site of the building.

No. 1 looked at Nan Qiyun, she had already begun to prepare an anti-pressure diving suit, in addition to Nan Qiyun, the other three people in the group were to stay in the submersible to respond.

"Wait." Nan Qiyun waved at her.

Half an hour later, Chen Tian's figure appeared in front of Hall 108.

Nan Qiyun froze. "All members, head to the ruins and follow the target." He gave the order.

Above the ruins building, nearly a thousand black dots quickly moved downward. It didn't take long for all the members of the detachment to arrive at the entrance of the ruins building. There is no sea water here anymore. The team members took off their heavy wetsuits.

They saw Chen Tian walk out of Hall 108, he paused outside the palace for a moment, lowered his head as if thinking about something, and then turned around and walked towards Hall 107.

All the members quietly followed in battle formation. Wright walked at the front of the detachment, and he was the first to quietly approach Hall 107, and after observing the situation inside, he gestured to the other members of the detachment that they could enter. Under the command of Nan Qiyun, more than 1,000 members of the detachment quietly entered the interior of Hall 107 in turn. Wright was left by Nan Qiyun near the perimeter of the main hall to be on guard.

In the empty hall, a long staircase rises in front of the members from the bottom up. It had been more than 300 years since Nan Qiyun last came here, and in his impression, there did not seem to be such a conspicuous building here, except for the bones found at that time.

About 100 meters above is separated by a large thick partition wall, with only a narrow entrance with steps leading straight to the entrance.

On the stairs, a black figure scurried upwards at the interface to the compartment. Nan Qiyun once again confirmed the integrity of the spiritual anti-interference device on his body.

"Keep up with the goal." He gestured to the detachment members.

Wright approached the steps first. The grayish-yellow steps were covered with dust, leaving a series of footprints that led straight to the top.

Everyone followed in turn. Nan Qiyun walked in the rear.

When he looked back, the steps he had walked on were faintly visible, and Nan Qiyun could vaguely see the ground below through the steps. He patted his head, but when he looked at it again, he didn't have the hazy feeling he had just now. Is there something wrong with the anti-jamming device? He thought so.

There didn't seem to be any source of light on the top floor, and the members turned on the illuminators they had with them, and strangely enough, the light from the originally powerful enough lighting device here was also faint, and they could only faintly see the surroundings within a radius of half a meter.

Figures gradually poured into the space on the steps. When the last members stepped up the stairs together, everyone's eyes blinked. It was as if illuminated by countless flashing lights, and without warning, the surrounding scene suddenly became extremely bright.

The members of the detachment let out an exclamation. Nan Qiyun looked around carefully, he couldn't believe his eyes.

Messy footprints, a huge staircase erected in the center, and above the staircase, the familiar entrance, quietly appeared in front of everyone's eyes. This is the place I just left. In the distance, there was also a group of supplies left behind by the members of the detachment to lighten the load.

Visual illusions! Nan Qiyun's heart was suddenly tightened, and when he turned around, the original entrance to the main hall had disappeared. Here, it becomes an enclosed space.

What about Chen Tian? Cold sweat gradually soaked through the clothes. If there is a problem with the mental anti-interference device, then it is very likely that the location of his group of people is not here, and the members of his own group are all staying on the periphery of the ruins, and if there is any mistake, he will even bury these people here.

"Go up the stairs." He glanced at the team members around him, who were not familiar with the situation when they first entered the ruins, and he hesitated to inform them about it.

An even more terrifying thought came to Nan Qiyun's mind, if he was in a hallucination now, then whether these people around him, including the team members standing beside him, were real? In the course of the previous operation, almost all of the team members died under the illusion of the ruins building. He took a deep breath and didn't let himself think about it anymore.

After more than a dozen reciprocating cycles, the eyes of the team members gradually dimmed, and everyone seemed to be locked in a closed space with infinite loops, and could only waste their physical strength in vain back and forth in the small hall.

They all looked at Nan Qiyun and stopped talking.

Nan Qiyun looked at these with a look of despair in his eyes.

Suddenly there was a scream from the crowd. A member of the detachment pulled out the dagger from his body and plunged it into the chest of the team member next to him.

His eyes gradually turned grayish.

Nan Qiyun was shocked. He remembered seeing this kind of gray-white sloppy eyes in the process of contacting government officials before.

That was after being completely reproduced by the "black body" and replacing existence. He raised the gun in his hand and pulled the trigger. The crowd screamed one after another, and dozens of daggers were drawn together in an instant, splashing a large amount of blood with the same action.

Dozens of familiar faces, their eyes covered with a dull gray. Order is in chaos. In just a few tens of seconds, almost all of them began to kill each other.

There is a little more warmth on the face. When he turned his head to look again, a blood-soaked knife came straight to his neck, and Nan Qiyun fired without hesitation.

He was grabbed by a strong hand behind him. Nan Qiyun subconsciously wanted to resist.

"Calm down." Wright said, injecting the tranquilizer into Nan Qiyun's forearm. The mind cleared up all at once.

He noticed that his clothes were soaked with blood, and in front of him, the members of the group who had participated in the operation fell to the ground.

He was holding a laser weapon with a hot muzzle and a little white smoke.

Nan Qiyun was a little stunned. "Them?"

"Dead." Wright hesitated for a moment and pointed to the gun in Qi Yun's hand. He shook his head.

Nan Qiyun's heart chuckled, and the feeling of dizziness was overwhelming.

"You mean、、、、、、" He was speechless for a moment.

Wright's eyes were filled with sadness, and this was the second time he had faced such a number of deaths so closely. "That's it when I came," he sighed, "and then, you swept down the last man. ”

The thousand-man detachment, except for Wright and Nan Qiyun, were all killed.

Nan Qiyun almost didn't react, he looked at the dead people in front of him, and then looked at the gun in his hand. The clenched hands suddenly lost their strength, and the body of the gun fell to the ground, making a "clang" sound.

His eyes suddenly became extremely frightened, and his hand was uncontrollably stretched out towards the dagger between his legs.

It was only a short fraction of a second, and Nan Qiyun's speed was unbelievably fast, and Wright subconsciously used his hand to stop him. The raised hand stopped in mid-air, and the dagger stabbed straight into Wright's throat. Wright looked at Nan Qiyun, his pupils dilating at an extremely fast speed.

In his last glance, he met the eyes of Nan Qiyun looking at him.

It was an off-white with despair written on it.

Wright's body fell in front of Nan Qiyun, and his hand rested on Nan Qiyun's feet. The armband of the "Trident" on the arm was drooping down, and the white letters "America" were stained crimson with blood spilled from the spatter. Underneath him, a pool of blood slowly poured out.
