The magical, completely incomprehensible energy field made all the technological creations in the group become decorations.

Once inside the energy field, the power armor becomes a veritable steel can, instantly losing all function.

As a last resort, after repeatedly confirming that there were no fatal factors in the external environment, Mu Yunshang ordered everyone to take off their power armor and prepare to enter the temple truly defenselessly.

In front of the pathfinder was a small team of royal guards, followed by Mu Yunshang and others, and behind was another team of guards.

The crowd cautiously marched through the passage.

"It's disgusting......"

Mother looked at the ground with a frown.

With the fluorescence emitted by the spore plants, people can clearly see their surroundings even without searchlights. At this time, the ground is covered with a layer of moss-like vegetation, which is slimy and very uncomfortable to step on.

Slowly, as the crowd advanced, the space around them began to become wider.

When everyone finally walked out of the passage, the scene in front of them completely shocked Mu Yunshang and her mother.

"Good...... It's so big......!!! ”

Mother subconsciously stretched out her hand and gently grabbed Mu Yunsheng's sleeve, stared at the vast underground space in front of her with wide eyes, and exclaimed.

A huge underground cavern is more than a football field just by sight.

Of course, the only people who were shocked were Mu Yunshang and her mother, Sango, they were all people who were used to seeing all kinds of big scenes, and such an underground space was not enough to surprise them just by the area.

It's just—

"What's that? Temple? ”

Mu Yunshang pointed ahead.

In the center of the underground space, there is a strange complex that looks like a temple.

The style of the entire complex was completely different from the architectural style of the alliance that Mu Yunshang had seen when he was on the surface before.

In the center is a large circular building, surrounded by several smaller arc-shaped buildings that serve as satellite halls.

Above each of the satellite temples was a dark blue diamond-shaped crystal that emitted a bright beam of light that shot onto a large crystal at the top of the central circular temple.

"Let's go!"

Mu Yunshang waved his hand, and everyone began to walk towards the temple.

The group was not slow to move, and although the underground space was huge, it didn't take them much time to reach the center of the temple.

It's an altar.

Mu Yunshang looked at the floor of the altar, which had a huge hollow carved pattern.

"This is...... Möbius Ring? ”

"No, Your Majesty, please see, this is an Ouroboros in the state of a Möbius ring."

Coral pointed to the center of the ring, and Mu Yunshang saw that there was a snake head and a snake tail there.

"Hell ............"

Mu Yunshang was amazed.

Of course he was familiar with the Ouroboros, but it was clearly a product of human civilization on Earth.

Walking to the center of the Ouroboros pattern, Mu Yunshang couldn't help but squat down and gently stretched out his hand to touch the junction of the Ouroboros' head and snake tail.

And then—

Rumble!!!!!!!

He seemed to hear a loud noise.

Not an explosion, but a roar that exploded directly in his head.

"It's you......"

"Finally...... Found you......

A murmur that he had never heard before sounded in his head, but Mu Yunshang found that his body was no longer able to move, and he couldn't even speak.

"Hurry up and prepare, you're running out of time......

"The whole world is running out of time......

A strange force spread along the Ouroboros into Mu Yunsheng's body, his pupils gradually turned silvery-white, and a small Mobius ring-shaped Ouroboros pattern slowly appeared on his forehead.

"Smash ——!!!"

The frightened mother ran up desperately, followed by Coral and the others.

However, with the exception of Mother, all those who tried to approach the altar were turned away by an invisible force.

The mother, who rushed to Mu Yunsheng's side, did not hesitate to reach out and grab Mu Yunsheng's arm and try to pull him up, but the moment her hands touched Mu Yunsheng, her mother's body was immediately unable to move.

"Oh......? There was another ......

It was that strange voice that had never been heard before, but this time it was heard by my mother in addition to Mu Yunsheng.

"Well, since this one is also there, maybe ......."

『…… This time, I will completely break out of this cycle."

In a trance, Mu Yunshang and her mother felt that there was a very terrifying existence in the underworld, and they were staring at them with a pair of eyes full of deep meaning.

The power that entered Mu Yunsheng's body through the Ouroboros also entered her body along her mother's arm.

Mu Sasaki, the younger sister who was originally sleeping in her mother's womb, was stimulated by this power and suddenly woke up.

"What is this......!? Not good!'

Feeling the immensity of that power, Mu Sashang found that if she didn't do something, her mother's body would collapse.

Thinking of this, she began to consciously absorb the power that had been transmitted into her mother's body into her own body that had not yet fully developed.

The three of them, including the yet-to-be-born Mu Sasaki, share a steady stream of power through the Ouroboros, and finally reach a very dangerous balance.

Finally, when the Ouroboros no longer provided strength, Mu Yunsheng, his mother, and Mu Sashang fainted instantly.

It was at this time that Coral and the others finally discovered that the invisible force that had been preventing them from entering the altar had disappeared.

"Your Majesty——!!!"

The guards swarmed Mu Yunshang and his mother, O'Neill picked up Mu Yunsheng, and Coral picked up his mother.

At the same time, the ground began to roar, and the entire underground space began to shake.

"It's going to collapse here! Come on! ”

O'Neill furrowed his brow and ordered an immediate retreat.

The group sped out of the underground space at great speed, and when they returned to the underground tunnel, the huge space with the temple finally collapsed.

"Hurry up! This tunnel is about to collapse! ”

"Come on!!"

After discovering that the power that had caused the empire's equipment to inexplicably ineffective disappeared, Night Raven immediately contacted O'Neill and them, and learned that Mu Yunshang and her mother were in a coma, so she immediately ignored the direct control of the spaceship and opened fire to blast the narrow tunnel in front of her and flew all the way over.

At this time, she didn't care if she would break anything.

In the hearts of the Imperial soldiers, Mu Yunsheng's safety far exceeded that of the Holy Land Gaia, which the Alliance cared about incomparably.

Finally, just as the tunnel was about to collapse completely, the ship and Corals managed to converge.
