The Crimson King.

Using this magic, Reiner was able to enter the quantum world in a short period of time, observe the fluctuating quantum tides, and naturally be able to detect and even use the subtle connection mechanism between the Xosaurons.

After explaining his spells, Reiner and the legendary mages arrived at the bottom of the Rainbow Tower.

This is the base part of the Rainbow Tower, located in the interior of the Floating Continent.

Reiner had never been here before, and this place was only recorded as a rumor in the books of the Rainbow Tower's Great Library.

This is the dungeon.

It is not the gloomy and damp scene that I imagined, the dungeon is made of gray stone, spotless, but rather a bit of a temple.

There were no prisoners in the cell, in fact, the last prisoner held here was three hundred years ago, just after the end of the modern magic revolution, a high-ranking mage, who was held here for three days because he was going to be put on trial.

Since then, there have been no prisoners left in the dungeons of the Rainbow Tower.

But at this time, they were not visiting the prisoners, but the Xenomorph of Sauron.

Walking down the corridor to a room at the end, Reiner stopped and looked at Lord Praggs beside him.

It has the strongest magical wall in the whole continent, and at the same time, the prison is built with extremely strong building materials, and it is difficult for even legendary mages to escape from it.

His Excellency Braggs bowed slightly, and an extremely complex magic array suddenly appeared on the simple white stone door of the room, which formed a series of solid locks, like the gears of the most precise machinery, moving the whole body, exuding a convincing majesty.

But these locks were untied one by one under the gaze of Lord Braggs, the runes dissipated, the circle dimmed, and finally, the stone door slowly moved and opened, revealing a path.

Lord Praggs was at the front, and Reiner was close behind.

It was a dark passageway, different from the bright scene outside the dungeon, where there was nothing to see except a road, and Reiner subconsciously extended it with his senses, only to find that it was not a wall, but an extremely empty field.

"This is an unstable half-plane, and the mages of the ancient Magic Empire have transformed this half-plane fragment into a prison."

Lord Braggs explained.

"In the past, at least two legendary mages and nineteen high-level mages were imprisoned here, and my teacher was once imprisoned here."

At this moment, the group walked on this path, as if they were walking in a dark abyss, there was only a small point of light in front of them, this staircase seemed to be endless, and in the darkness there seemed to be countless monsters with their teeth and claws, trying to tear apart the travelers who visited this place.

"A special illusion has been applied here, and if it can't be broken, then it will be forever walking on the stairs, unable to reach the end of the road ahead or return to the entrance where it began."

Master of the astrological system, Lumia. Lord Calvados walked behind Reina, she explained.

"The immutable vision is easy to mislead, and with a certain amount of visual error, it's easy to get lost, like, do you really think that the ladder you are walking is the only one?"

Hearing the words of Lord Calvados, Reiner carefully observed the staircase, and after being reminded, he soon discovered that there was indeed more than one staircase here, and that some of the stairs were connected to the correct path in such a clever way that it was easy to go astray without warning, to be afraid of the darkness outside, or to look only at the point of light ahead.

Once they go astray, they are visually misled, confused by illusions set up by magic, and eventually walk on a circular ladder until they die.

However, since Lord Praggs is leading the team, these illusions are not worth mentioning at all.

The light grew stronger and stronger, and Reiner eventually saw a strangely shaped building, suspended in mid-air, connected to a staircase, like a block made of stone, quite contrary to the traditional style of the ancient Magic Empire.

Reiner felt a strong sense of déjà vu, and it wasn't until he reached the entrance of the building that Reiner had the same architectural style as the creatures from the previous era in the Dead Lands of the Far North.

"Here"

Reiner looked at Lord Hohenheim behind him, and the other party did not speak, only took a deep look at the building.

"This is now holding a specimen collected from our first encounter with Sauron many years ago, it was frozen by spells, immobile, and completely dormant, and we studied it at the time, but found nothing, so we stored it here for a long time."

Preston said that he had observed the biological tissues of Sauron's xenomorphs, which were similar in composition to other animals, but apparently stronger in structure, and from the examination of the corpses, the creatures were not identical in shape, but the internal structure was strikingly similar, and Preston speculated that they may be the product of gene editing.

As long as you can control your genes, you can change your traits, and the people of the last era must have mastered this technology very well, which is why they created monsters that even they could not destroy through gene editing, and finally ushered in the end of the world.

The square building was very spacious, similar to the one in the Far North, with no doors or windows except for an entrance, except that the items in the building were Reiner's familiar laboratory table, and in the center of the hall was a transparent display case.

Approaching the display case, Reiner sees an ugly creature.

It has a humanoid appearance, dozens of eyes on its head, and six thick, swarthy arms, which end not in palms, but in sharp black thorns, like the multi-legged of insects.

With its two short legs and an insect-like anti-articulation, the monster has two pairs of white wings behind it, which look like a disgusting fusion of humans and insects.

It just lay in the display case, surrounded by countless magic circles, imprisoning it in it, and for fifty years it had not left a trace on this monster, it seemed that it would suddenly wake up in the next second, and slaughter everyone present.

"I'll try to do it while it's hibernating."

Reiner said, holding out a hand that could be seen as the tips of the slender fingers blurred like smoke, emitting particles of light that drifted towards the dormant Sauron xenomorph and melted into it.

In the next moment, Reiner felt a myriad of information flow into his brain, and his eyes widened.
