After Lin Yuan left the nest for a while, Ni Ji followed him out quietly.

This was not the first time he had sneaked out after Lin Yuan left.

It was dangerous, he knew. If Lin Yuan found out, the trust relationship that he had worked so hard to build would deteriorate in an instant.

But he had to act. He wanted to find out the secrets here and find out why Lin Yuan lost her memory. He wanted to find a way to make Lin Yuan recover and take her away.

Ni Ji sneaked all the way, releasing the sentinel's perception ability to the maximum, and listened attentively to every subtle movement in the distance.

At the same time, I completely suppressed my outward emotions, making myself like an ignorant and unconscious creature, quietly lurking in the darkness.

He has known Lin Yuan for a long time, and they often cooperated in battles. He is very familiar with Lin Yuan's way and style of exploring the world, so he also knows how to avoid Lin Yuan's spiritual perception ability.

It's difficult and dangerous.

All the creatures here are well adapted to the darkness, move silently, and have sharp hearing. They will detect the slightest movement.

You have to avoid all the deformed creatures and not be noticed by Lin Yuan.

For this reason, Ni Ji patiently trained himself for several days to recover both his physical and mental strength.

Quietly, carefully, and with all your strength.

Follow all the way.

At a great distance.

He could clearly hear the unique wriggling sound of the tentacles as they moved.

Lin Yuan is talking to that Teng Lu.

Ni Ji stopped and listened, feeling that they were walking through a long corridor.

He heard what Fujilu said.

"You can turn up his sensitivity tenfold, or even a hundredfold, and then he'll cry for mercy at the slightest touch."

"There are more things that can be done in the mental picture. The sentinel will find that he doesn't even have a chance to beg for mercy. Hehe, that's the most interesting moment."

"You'll get used to it soon and like this feeling. Here, there are many sentinels entering every day, and there are plenty of toys for you to choose from. There's no need to pay too much attention to one person."

"You pamper the sentry too much. He will run away sooner or later."

Ni Ji hid in the dark ceiling, holding his breath, listening to the sound of their footsteps getting farther and farther away.

He counted the distance they had moved forward in his mind and estimated the direction they had turned.

Finally, he heard Lin Yuan's voice, "He won't, he promised me."

That trustworthy voice struck his heart and made his brows droop slightly.

He heard a heavy door being pushed open and Lin Yuan and Teng Lu went in.

Ni Ji waited until they were completely gone, then silently jumped down from the roof and bypassed a mutant guarding the door.

Following the footsteps of Lin Yuan and Teng Lu, we walked into the long passage.

This place is very similar to Lin Yuan's nest, probably they are connected somewhere.

The passages inside are interconnected, with countless forks in the road. The dark corridors are silent, with only the occasional dripping sound from the groundwater dripping from the roof.

This is a huge maze deep underground.

The maze covers an extremely large area. If it weren't for the two people in front leading the way, Ni Ji would never be able to find such a deep place on his own.

He moved forward quietly in the darkness, occasionally turning on the dim flashlight on his shoulder.

As we walked deeper, the decorations on the walls became increasingly gorgeous, and many tall and huge statues appeared on both sides of the long corridor.

Those strange sculptures crouched on the roof and on both sides of the walkways, looking down at the sentinel who was sneaking into the darkness alone.

Ni Ji's fingers gently stroked the wall. The tall underground palace had cold and hard walls made of special metal.

There are countless exquisite murals carved on the smooth and clean walls.

When Ni Ji's fingers slid across the murals, the metal lines glowed softly, revealing the stories recorded in the darkness.

Ni Ji had occasionally seen murals of this type in other polluted areas.

Some fragmentary murals have appeared on the palace gate in Contaminated Area No. 5 and on the inner wall of the cave where the Scarlet Egg is located.

It seems that no one has paid any attention to these paintings.

There is no official organization that has compiled, collected, or made public any of this information. It seems that for humans today, history is irrelevant, and the most important thing is to survive.

Ni Ji raised his head and looked at the huge murals in front of him.

This was the first time he had seen such a vast and continuous mural.

The fluorescent lines moved like flowing water following Ni Ji's touch.

A large mural appeared in front of Ni Ji, completely recording the story that had happened.

First, a huge cruise ship, the sailors found a strange egg in the deep sea. It was some unknown creature on the seabed that contained huge energy.

Everyone on the ship was extremely happy. In that era, human technology was highly developed, but energy shortage was the biggest problem facing mankind.

On the mural, a silver-haired man wearing a captain's hat held up the box of insect eggs and said, "We will change the future of mankind."

The lines of light moved and came to the next group of murals.

Most of the crew on the cruise ship began to behave strangely.

The side of the painting is labeled "The Beginning of Human Deformation"

A fierce battle broke out between the deformed monsters and the normal crew members. More and more crew members were infected and mutated. The situation became out of control.

In order to prevent such pollutants from being brought back to land, the captain made a tragic decision to sink the Maria along with all the people on board.

There is an inconspicuous picture on the mural.

The captain locked the box that once held the insect eggs - a wooden box inlaid with exquisite gems, exquisitely crafted and simple in style - into the secret compartment of the table.

Ni Ji frowned and stroked the small mural with his fingers, making it light up again and again.

The captain in the picture looks sad, holding up the small box as if holding on to his last glimmer of hope.

The small box looks brilliant and exquisite, as if it has magical powers, similar to the technology of these walls, which can light up corresponding historical pictures under certain conditions.

It's just a mural. No matter how finely it's carved, you can't see the whole picture.

But Ni Ji felt that the box looked very familiar. He thought for a while and remembered that on the Golden Beach in the No. 5 Contaminated Area, Lin Yuan handed over all the precious energy stones and only hid a shabby wooden box.

It was just a tattered and inconspicuous box, completely different from the brilliant treasure box on the mural.

But Ni Jimin keenly felt that the two boxes were the same thing.

Ni Ji's fingers slowly slid across the lit screens, thinking of the lonely girl.

It turns out that she was alone, searching for some huge truth buried by history.

The lines of flowing water illuminate the pictures. The Mary sank tragically in the sea, but it could not stop the spread of the distortion.

The crew members who turned into monsters crawled all the way back to the shore from the bottom of the sea and entered the human world.

From that moment on, humans were infected in large numbers and transformed into powerful deformed creatures. Cities fell one after another, and the era of great destruction arrived.

The golden age of mankind, which was once glorious and technologically advanced, is collectively referred to by later generations as the "Old Days".

Ni Ji saw this underground city among the many flashing murals.

This was once an underground bunker built by humans for refuge after the deformed creatures spread around the world.

In order to take back the skies for mankind, countless scientists are developing powerful weapons deep underground.

One group of researchers hatched a worm jade, raised the ancient monster to maturity, and mixed its blood into the human body.

Finally, the strongest humanoid weapons at that time were born, the Sentinel and the Guide.

Ni Ji looked down and saw that the sentinels and guides formed a powerful team, carrying mankind's high-tech weapons and fighting back to the ground.

They attacked cities and plundered villages, advancing triumphantly all the way, and taking back piece after piece of human land.

That was history hundreds of years ago.

The mural shows soldiers with high morale, marching to battle with powerful ships and cannons at their backs. The people who see them off are jubilant. Humanity looks very happy.

Ni Ji stroked the wall with his hand, looking at the murals that glowed brightly in the darkness.

There is no record of what happened next.

Why did mankind go from that moment to the present state of decline?

Why did such a prosperous and huge underground city become an empty city and degenerate into an underground lair inhabited by monsters?

Before he had time to think carefully, Ni Ji heard some noise coming from afar.

In the darkness, there was a large-scale rustling sound. What was that? Something wet was moving quickly.

It's the tentacles. They are moving away from the center of the temple at an extremely fast speed.

They ran straight towards their direction without hesitation.

Ni Ji's pupils shrank.

Discovered!

He turned and ran out.

The passages here are complicated and the vision is pitch black. But Ni Ji is a powerful sentinel with superb perception and extremely fast speed.

When he ran at full speed, almost no one could catch up with him.

The mutant guarding the entrance of a passage noticed the movement and just as he raised his head, a flash of blood-red knife light passed by and cut it in half.

The sentry jumped over its stump and ran away without stopping.

He could feel countless monsters gathering behind him and chasing in the direction he was running.

Among them, the sound of the tentacles crawling and surging mixed with the sound of water is the most obvious, with great momentum and a tight bite.

She was angry.

Ni Ji thought so while running away.

If I get caught by her again this time, maybe she won't be like last time and let me go so easily.

Maybe, I will die at Lin Yuan's hands.

This thought flashed through the sentry's mind, and he felt sad and didn't want to think about it anymore.

With long legs flying, a figure rushed out of the dark tunnel like an arrow.

At the tunnel entrance, the mutant waiting there was huge, with a humanoid head and a long snake-like neck.

Ni Ji rushed out of the cave, drew his sword, stabbed the monster's skull with the sword, and flipped over its head covered with long algae.

This is a fork in the road, with two roads.

Turn right to the forest garden's lair, and turn left to the escape staircase to the upper floor.

Turn left and run upwards to escape from this underground abyss. But it is probably impossible to break down again and return to Lin Yuan.

Turn right and enter the cave of the forest garden. You are doomed to be captured as you are surrounded by many monsters.

Afterwards, he would most likely be executed, imprisoned, or die in those familiar white hands.

The sentry standing at the fork in the road stopped.

The long-necked mutant caught up, its pale neck like noodles wrapped around it, and it opened its bloody mouth, trying to bite the outsider to pieces.

At that moment, facing the monster's dripping saliva, Ni Ji felt a sense of despair in his heart, and he almost wanted to let the monster bite him to death.

I really don't want to face Lin Yuan and her disappointed and angry face.

The red blade continued to grow like a sharp claw. Ni Ji held the knife in both hands and split the giant mutant in half from the crack in its skull.

The long sword was bright red as it chopped down along the long neck, tearing the python-like monster apart.

The blade's force did not abate, red light flashed out, ferociously and domineeringly, chopping the monster's body into pieces.

When Lin Yuan caught up, she saw her sentinels chopping up the bodies of countless deformed creatures around her.

He sat on a pile of bloody flesh, holding a long knife with a ferocious look on his face.

Countless mutants rushed in from all directions and crouched in the darkness, making low guttural sounds.

They had surrounded him, but he was so frightened that he dared not move forward.

Lin Yuan's tentacles moved around and took her to the platform. She perched on the high ground, staring at the sentinel sitting in the circle of monsters.

When Lin Yuan found out that the sentry had deceived him, the anger in his heart was like boiling water. No matter what, he couldn't suppress it.

She actually didn't understand why she was so angry.

Fujilu is right, many humans and many sentinels enter this place every day.

The one in front of her was disobedient, so she could just abandon it. She could just go up a few floors and catch another one. It would be easy to get any number of sentinels she wanted, no matter what kind.

She actually doesn't mind being deceived. Teng Lu always smiles in front of her, but she actually knows that Teng Lu hides a lot of things from her. She just doesn't care, at least she's not angry.

Why? When I found out that Ni Ji had deceived me and tried to leave me, I felt so angry?

Lin Yuan couldn't understand.

Fortunately, he did not run away, but returned to the outside of the nest and waited for me here.

Lin Yuan walked around the sentry and felt a little better.

If he had not turned back to the nest but instead fled towards the ground, she didn't know what terrible thing would have happened.

A tentacle reached out and bound the sentry's wrists, and the tip of the tentacle lashed the skin on the back of his hands.

The sentry resigned himself to his fate and threw away the bloody red knife.

Another tentacle swam up, wrapped around his tight penis, and lifted him up.

The bound sentry turned his head away and whispered, "No one else."

From all directions, the mutants lurking in the darkness let out mocking screams and growls.

Lin Yuan only said one word, "Get lost."

No one understood what she was thinking, but every underground creature knew that she was furious.

Want to stay and watch? The noisy mutants all retracted their necks and dispersed in an instant.

Ni Ji was tied up by the tentacles, dragged all the way back to the nest, and thrown to the ground.

The bonfire in the den had long gone out by now, leaving only the flickering glow of the charcoal in the embers.

Ni Ji looked up and saw Lin Yuan perched on the wall.

Her expression was cold, like a sculpture wearing a ceramic mask.

Ni Ji thought of the murals he had seen and the strange sculptures standing in the corridors of the temple.

From those murals, he knew that in this polluted area isolated from the outside world, in this dark underground city, there once was a huge creature with powerful spiritual power, called a god, who supported the operation of this world.

Now the monster is gone, and Lin Yuan has taken its place.

Looking at Lin Yuan, who had no expression on his face and had completely lost his memory in the darkness, Ni Ji felt an unspeakable sadness and anger in his heart.

Now he knew why the Queen sent only one guide, Lin Yuan, to go deep into such a dangerous contaminated area.

Although I don't know for what purpose.

But it was obvious that they sent Lin Yuan deep in here to complete such an impossible task.

The purpose is to make her look like this and become the pillar here.

Ni Ji had many good teammates, all of them were very nice and lovely people.

However, they were sent into the contaminated area by the upper levels of the White Tower and lost their lives for no reason.

Now, he has nothing left but this guide.

His only companion, a warm and strong girl.

But those people sent her here again, causing her to lose all her memories and turning her into this cold and heartless person.

She is obviously such a good person, as warm as the moon.

Those people wanted her to fall into the abyss, become a man-eating god, and live forever in this dark underground.

The fire of hatred burned in the sentry's heart, turning that red heart into a piece of hot iron.

He hated this filthy world and the white tower that seemed pure white.

He thought angrily that as long as he was still alive, as long as he had a breath left, even in the most dilapidated form, he would one day climb back to the white tower and overthrow the stinking tower and the corrupt empire.

In the dim nest, there was the sound of dripping water.

A dark red flame smeared on half of Lin Yuan's face, while the remaining half was plunged into deep black.

This place no longer looks like reality, almost like a dream.

A scarlet and terrifying nightmare that Ni Ji had once witnessed.

He looked at Lin Yuan's face, which looked cold and distant.

On the battlefield, most of the time when they were together, Ni Ji was the more rational and calm one. Lin Yuan's thinking was very jumpy and sometimes very emotional.

But Ni Ji knew that Lin Yuan was actually more resolute and resolute than himself. As long as she was determined to do something, even if he pulled her and begged her, she would still go forward resolutely without looking back.

Now that she has completely lost her memory, she might really punish herself ruthlessly.

This time she was really angry. After all, she was the one who was deceived.

The girl with a cold look was crouching in the dim nest. She had an expressionless face as she walked down from the crisscrossing walls of the pipes.

Ni Ji felt an inexplicable panic in his heart.

He repeatedly reminded himself that he was a soldier who had experienced many battles and that no physical torture or interrogation would be unbearable for him.

Even if he was abused and tortured, he could endure it. Wasn't the physical torture he experienced in his life enough?

As long as Lin Yuan lets him live, there is still chance and hope.

Ice-cold tentacles wrapped around his limbs and secured them in place.

Ni Ji looked at Lin Yuan with disdain as he came to him, and said coldly with his lips slightly parted,

"To punish you for lying, I'll raise your sensitivity tenfold."
