In the middle of Poyang Lake, several ships painted with na symbols were quietly parked on the lake surface. Soldiers wearing exoskeletons stood on the side of the ship, holding rifles, and carefully guarded against the underwater conditions.

On this wasteland, places with water are always more dangerous than places without water. Behind each aquatic plant, there may be the figure of sludge crabs. These alien species covered with heavy armor will not benefit even if they encounter dead claws.

Wearing painted black power armor, Jiang Chen stood at the bow of the boat and glanced at the bottomless lake.

The clear lake surface slowly ripples with discipline. If it weren't for the conclusive information, no one would believe that such an amazing secret was buried under this lake.

Two thousand scientists from all walks of life in research fields, this "treasure" is really important to Jiang Chen.

After a while, a knight walked behind him and bowed respectfully.

"The observer has scanned it with his life detection device, and there is no trace of sludge crab activity within a mile. Our people are also ready and can set off at any time."

"Then let's go now." Jiang Chen ordered.

"yes!"

The fist hit the steel chestplate and made a neat sound. Hu Cheng respectfully saluted and turned around and took the order and left.

Under the leadership of this na Knight, five soldiers wearing amphibious mechanical exoskeletons quickly gathered at the bow of the ship and jumped into the lake in sequence with a command.

Jiang Chen stood at the bow and waited quietly until the advance team underwater confirmed that the lake was safe, and then stepped into the lake.

As a single soldier armor that can cross the nuclear radiation area, the average water depth is only about ten meters, which is naturally no problem for the T3 power armor. After a while, Jiang Chen's feet steadily stepped on the soft lake bottom.

One or two mutated fish swam over and bit the steel shell with their crooked teeth. Jiang Chen waved his hand to drive away these mutated creatures who were overestimating their abilities and walked towards the marked position in the holographic screen.

Like most refuges, this refuge, which is not built, has an entrance with a circle with a diameter of more than ten meters. It is just that it is not embedded in the wall, but is embedded at the bottom of a lake with overgrown water plants.

Time has left no trace of rust on its body, and the shiny alloy seems to have been cast yesterday. In the center of this circular giant door, the words t7 are painted.

"That's it."

A string of bubbles rushed out of the gap in the armor. Jiang Chen looked at the knight who was also wearing power armor and nodded. The string of ruby-inlaid pendants taken out from his waist walked towards the center of the giant steel gate.

"Let me do it." Hu Cheng hurriedly stepped forward to stop the marshal and volunteered.

As a knight of Na, how can you make the marshal take risks?

However, Jiang Chen just shook his head.

"It's okay, there is little possibility of organisms here."

The entire 118 refuge has been incorporated into the banner of Na, and Lu Yihua has no reason to deceive himself.

Only graves require the mechanism of guarding the tomb. If it is to send knowledge and hope to the future, then the person who built this refuge has no reason to put weapons into it.

In the center of the Giant Steel Gate, as Lu Yihua described, a circular concave can be seen.

Jiang Chen put the silver disc at the end of the pendant on it and gently rotated it to the right for half a circle.

The ruby ​​inlaid in the center of the disc is the core of the key. After special gem processing technology, dozens of g of passwords are engraved in the construction direction of the shelter. The secret key made using this encryption method cannot be deciphered even by the computing power of experimental quantum computers.

The current passed through the silver disc.

A string of bubbles emerged densely from the edge of the circular steel giant gate and rushed towards the lake.

With a slight tremor, the Giant Gate began to slowly sink.

"What's wrong here... Marshal, please come out first." Hu Cheng quickly stepped forward to protect Jiang Chen and looked around nervously. The five soldiers wearing amphibious exoskeletons around him also nervously set up the underwater rifle in their hands, alerting to possible threats.

"Don't be nervous, it's just an elevator." Jiang Chen smiled and shook his head, reached out to press down on the muzzle that Hu Cheng had raised, signaling everyone not to be nervous.

Everyone slowly sank with the steel Giant Gate. In less than half a minute, the Giant Gate that had originally protruded to the surface had turned into a deep pit. When the Giant Gate sank to a certain height, the entire Giant Gate was fixed there with a "click" sound like a bullet entering the chamber.

The top of the deep pit began to close, like a dome covering the heads of everyone, sealing the exit.

When the dome is completely closed, the signal lights in the deep pit light up, illuminating the entire space.

Immediately afterwards, the water level began to drop, and only after it was completely emptyed, the vertical well wall slowly moved a door away.

"So this thing is not a door, but an elevator."

He looked around and saw a steep steel wall wherever he saw it. Hu Cheng put away the underwater rifle in his hand, muttered to himself, and took off the tactical rifle at his waist and put it in his hand.

At this time, Jiang Chen had already walked to the open iron door.

But just as he was about to step over the door, he stopped with a frown.

On the open iron door, he saw a familiar sign.

He reached out and touched the raised badge gently, and the fingertips covered by soft alloy followed the lines and swept away the dust on the outline. If he remembered correctly, the company that owns this trademark had a loud name.

"East Asia Heavy Industry..." After retracting his hand, Jiang Chen murmured with this name.

"What's wrong?" Hu Cheng, wearing steel armor, walked to his side, picked up the flashlight and looked at the darkness behind the door, but except for a long and narrow corridor, there was nothing special.

"Where is that string of pendants? Take it down and give it to me." Jiang Chen turned his head and looked at the knight who came down with him, and ordered.

"yes!"

Hu Cheng nodded respectfully, walked back to the center of the circular giant door, bent down and took the pendant out of the groove, and sent it to Jiang Chen.

After taking the pendant from the knight's hand, Jiang Chen waved to the soldiers behind him, signaling them to follow, and then walked towards the corridor.

Under Hu Cheng's leadership, the six people held rifles and protected Jiang Chen steadily.

Soon, the group arrived at the end of the corridor.

Jiang Chen took out the key again and put it on the card reader of an alloy door and scanned it.

After reading the password in the ruby, the alloy door slowly opened, and the cold light that opened successively lit up the dark space. Gradually, he saw a spectacular scene behind the door, and Jiang Chen's pupils gradually expanded, and a surprising color bloomed.

Like Terracotta Warriors, in a space covering an area of ​​tens of thousands of square meters, there are about two thousand oval dormant slept. The white shell is like a goose egg that is slanted, wrapped by pipelines as thick as forearms, entangled with the center's main control computer and life-saving device.

This is not a refuge, but a time machine.

From the past decades ago to the future today, what is carried is the spark called civilization.

"Wait for me here."

Leaving this sentence, Jiang Chen walked towards the big dome closest to him with the indescribable excitement in his heart, and reached out and pressed the button with the words "End of Sleep".

The smooth "cylinder shell" opened a neat slit, and cold white mist sprayed out from the gap.

Like a rebirth after breaking out of the cocoon, the shell of the dormant chamber slowly opened, revealing the girl lying in the shell with her skin as smooth as mutton fat jade.

However, when Jiang Chen saw the man's face clearly, his excitement suddenly felt like a basin of cold water was poured on it, and it quickly cooled down.

Suddenly thinking of something, he raised his head suddenly and looked at the main control computer in the center.

This familiar device...

As if confirming his guess, the cold and silent display slowly lit up, and a man in a suit appeared in the center of the screen.

He sat in an office chair, behind him was the night view of Wanghai City before the war.

The expressionless face seemed to be indifferent to everything.

"Hello, my future friend... Looking at your expression, have you seen me somewhere?" (To be continued.)
