Li Ang moved in the direction from which Shin's voice had come from, gradually approaching a large room in the deepest part of the corridor.

The door was closed, there was no keyhole, and there were no chain hooks, and Leon tapped it with a dagger, but there was a muffled sound of a special structure of reinforced concrete and concrete.

"Squeak...... Squeak crunch...... Squeak~"

The door opened, revealing a narrow passage that could only be passed by one person.

Leon took a deep breath, held his breath, and slowly slipped in, and through the faint light, he saw rows of iron shelves at the end of the passage.

A mangled body hangs from an iron shelf.

The mutilated bodies were men and women, old and young, in a variety of postures, some were bitten to death by sharp teeth, some were chopped to pieces by axes, some were pierced through their stomachs, and some retained their intact appearances.

Leon knew that the owners of these shells were the alien legions that participated in the slaughter of human countries, many of which were mutated beasts summoned from the earth, and even some androids and mutated plants.

They are trapped in cold steel cages, quietly waiting to die.

Leon looked closely for a few minutes, and found that their muscles were atrophied, their bones were fragile, their body temperature was draining rapidly, their pupils were dilated, their lips were purple, and they seemed to have been dead for a long time.

"Looks like I guessed wrong." The dense runes contained an inexplicable fluctuation. "Bowing down" is like praying, and it is like worshipping something.

A wisp of green smoke hung from the old man's head, and it seemed to be a thin skull, his eyes closed and silent.

"What the hell is he trying to do? Do you want to summon an evil god to come? Leon's eyebrows furrowed, and his heart beat faster.

At this moment, a faint green flame suddenly lit up in the corner of the secret room, illuminating a vague picture.

The scroll is made up of countless fragments, with only a few twelve, each of which is lifelike and vivid.

On the left are three masked men dressed in black.

On the right side are six strong men who are more than two meters tall, wearing armor and helmets, holding spears and halberds, riding on horseback, they are wearing silver and gray battle robes, swords hanging from their waists, majestic and majestic, and the killing aura permeates the whole body, just like a heavenly soldier and a god general.

The four patterns on the left side are four majestic cities, some of which have a golden scepter on the top; Some are carved with hideous ghosts, fierce lions and tigers, strange fish and birds; Some are four white-clothed men with delicate faces; There is also a pitch-black portal.

The pattern in the middle depicts an ancient dynasty, with a raging fire burning in the palace hall, and four giant stone pillars entrenched with hideous dragons and phoenixes.

Each of the four motifs corresponds to an emperor and a queen, and in front of the palace hall stands a majestic statue of a majestic warrior wearing blood-red heavy armor and holding a giant blade, its head inlaid with a dazzling sapphire, and the fire burning in its eye sockets.

"Is this the so-called 'four phases'?" Leon whispered.

In the center of the scroll, an old man in black with a wrinkled face and a hunched body is worshipping the warrior sculpture reverently, with words in his mouth and an old and hoarse voice.

Then, he looked up and looked around with burning eyes, as if he could look through the walls into the depths of the chamber.

The old man stood up, walked towards the scroll, reached out and stroked the sculptural head, and whispered, "You are finally here." ”

As soon as the words fell, the scroll shook violently, and the four patterns slowly disappeared, only the mighty giant appeared again, and the armor on his body quickly fell off and fell to the ground.

The old man in black laughed, walked up to the giant, and reached out to grab the giant's arm.

Click!

The dark underground cell suddenly brightened, and the giant turned into crystal-clear pieces that were stacked into a crystal staircase that led to deeper secrets.

"Here, it deserves to be called the 'sacrificial hall'!"

The old man in black looked up to the sky and roared, shaking his eardrums.

……

"This is the so-called 'sacrificial hall'?"

Leon hid in the shadows, looking at the magnificent sacrificial hall from afar, his heart beating wildly.

Thousands of meters high, this sacrificial hall occupies an entire underground passage, and the dome is made of thick alloy plates, emitting a faint dark red light.

In addition, the whole building is richly furnished, the walls are inlaid with various rare treasures, the floor tiles are also a rare material with a lot of price, and even the carpet under the feet is made of some kind of precious animal skin.

The sacrificial hall was empty, except for a round table in the center, which was covered with clean yellow satin.

There was a corpse lying on the yellow satin, with wrinkled skin, vicissitudes of life, gray hair, eyes closed, and no scars on the body, but it had lost its vitality.

Leon squatted in the shadows, looked at the corpse for a long time, and suddenly thought of something, and hurriedly took out his pocket watch to check the time.

Five seconds had passed since he entered the "sacrificial hall".

"Damn, what's so dangerous here!"

Li Ang was anxious and hurriedly retreated to the underground cell.

"Bang!"

As soon as Leon pushed open the iron door, he heard a dull crash inside, as if some behemoth had collapsed inside.

Startled, he hurried into the house and saw the strange woman in the cloak sitting on the ground, holding a round egg.

"What is this?"

Li Ang was stunned for a moment and looked at the egg carefully.

It is the size of an egg, translucent, and contains a liquid-like substance, with countless intricate symbols floating on its surface, vaguely outlining a beautiful female face.

The woman's face is lifelike, her eyebrows are full of charm and enchantment, her body is slender and exquisite, concave and convex, curves are graceful and seductive, her chest is straight and firm, her waist is soft and slender, and her black hair flutters like a waterfall.

"This ...... How could it be ......"

Leon rubbed his eyes, convinced that the face was what he remembered.

He was so shocked that he couldn't believe what he was seeing.

That corpse is actually ......

"This is the 'Sacred Egg', one of the only three remaining Sacred Eggs in the world."

The witch spoke slowly, gesturing to her bosom, "I've searched the entire underground ruins, and only found this one.

This is where our hope lies, and when hatched, we will have extraordinary abilities that will lead us to conquer the world. ”

Leon glared at the witch and asked, "Hatching?" What to hatch? ”

"I don't know."

The witch shook her head, handed the egg to Leon, and said, "You take it first, we must get out of here, or we will be discovered." ”

Leon took the egg and looked around, seeing that there was only one tunnel that meandered and stretched deeper.

"What is this?" Leon pointed to several skeletons on the ground and wondered.

The witch glanced at it and said indifferently, "It's the corpse of the guardian." The environment here is too dangerous to stay long, so let's get out of here. ”

"Oh." Leon nodded in agreement, and followed the witch as he scurried down the narrow tunnel.

Soon, Leon saw a sudden opening up in front of him, a huge arch bridge spanning the entire space, and the river under the bridge was turbulent and surging.

"That's the underground river, which runs through the entire mountain range."
