I accidentally pulled out the black light virus and I became invincible.

Mercer did not go home, but came to the Holy of Holies first. Ganata was not willing to follow her here, so Mercer sent her back to his home first.

Now in the Holy of Holies, without the Ancient One, no one would know that Mercer came here.

He was wandering around the Holy of Holies alone, and with the existence of the Cosmic Rubik's Cube, Mercer could avoid everyone's eyes very well, and no one could see him at all.

"Is my deduction wrong? Are you really going to save that Ancient One?"

Mercer frowned. If this was the case, he would rather not complete this task.

After searching to no avail, Mercer sighed and was about to turn back home when he suddenly stood where he was. A gentle gust of wind blew on his face, causing him to turn his head instantly.

The location he is currently on is the highest floor of the Holy Sanctuary. It is considered the office of the Supreme Mage. Normally no one would come here.

There were many weapons and books placed here, including magic weapons and magic books. Mercer looked away after taking one look at them. In his eyes, these were just a pile of rubbish.

Mercer walked to the bookcase on the right and looked at the books on it. He clearly felt that the wind was blowing just now.

After standing in front of the bookshelf and staring at it for about ten seconds, Mercer grinned and said, "It's old stuff."

Mercer stepped forward, space ripples appeared on the bookshelf, and he passed directly through it.

Behind the bookshelf, as expected, there is a dark passage.

The path is made of stone bricks. Many of the stone bricks have grown moss and look like they have been there for a long time.

At least I can be sure that it was definitely not built in the past hundred years.

In this atmosphere, Mercer could vaguely guess what would be at the end of the trail. He moved and quickly jumped towards the depths.

The path was not deep, and after a few seconds, Mercer could already see the wall at the end.

Dark, damp, and narrow, these are Mercer's three views on this trail. "This is simply a perfect place to imprison people, and it is too villainous."

"Who... is here?" A weak voice sounded at the end.

Hearing this voice, Mercer was startled and looked up. At the end of the path, there was a small platform similar to an altar. There were pillars erected on both sides of the platform, and a black chain shot out from the top.

Between the two chains on the left and right, the person trapped is that familiar face, Ancient One!

"You, how did you become like this?"

Mercer hurried over and took a closer look. The body of the Ancient One in front of him looked a bit unreal.

Soul body?

The state of Gu Yi in front of him can be seen even by an ordinary person standing here. His body is illusory, and his original feet are empty, and they have dissipated until the middle of his thighs. He is completely in the state of a soul.

"After so many years...you...are the first person to come to this...place. Who...are you?"

Gu Yi's voice was very weak, and his eyelids were drooped. If Mercer hadn't directly sensed her energy, he would have thought she was about to die.

"That's not important. What's important is that I save you first."

With that said, Mercer was about to dismantle the two magic pillars next to him, but Ancient One stopped him.

"Don't...this pillar has strong protection. No one can open it except her..."

Who was the "she" in Gu's mouth? Mercer knew without even thinking about it. He grinned his big white teeth and said, "Don't worry, I'm a professional in magic."

As he spoke, Mercer opened his eyes wide in front of Ancient One. In the latter's surprised gaze, his blue-green eyes suddenly turned into the Mangekyō Sharingan.

After glancing up and down at the two pillars, Mercer smiled and said, "A simple old trick."

Mercer raised his hands and formed hand seals with his hands. The golden magic power outlined a palm-sized seal in front of him.

The gesture stopped abruptly, and Mercer put his right hand against the seal and slapped it against the two pillars.

The magic pillar that had imprisoned Gu Yi for who knows how many years was shattered from top to bottom.

Gu Yi lost his restraints and fell directly to the ground.

"The seal...is broken?"

Gu Yi looked at the two pillars next to her in disbelief, and then at the smiling young man in front of her. Seeing the clothes she had never seen before, she was stunned for a moment and said slowly.

"What year is it now...?"

Hearing this, Mercer hesitated for a moment and said, "It must have been a long time since your time. I would rather hear how you were trapped here by her."

Gu Yi let out a long sigh and recounted everything.

She was from the mid-seventeenth century. At that time, she was young and extremely talented. She became the most powerful mage at the age of only twenty-three.

At that time, the Ancient One was the most dazzling figure in the magic world, with a prominent reputation. He led the mages at that time to resist many attacks from magic forces from other planets or other dimensions.

Because of this, the power of Earth mages began to spread throughout the universe.

There are also many extraterrestrial magical creatures who see the most fatal limitation of Gu Yi as a human being, which is lifespan.

The lifespan of humans on Earth is about a hundred years, while many creatures on other planets have lifespans of between 150 and 200 years.

At that time, the Ancient One established the Holy Sanctuary in order to protect the earth from attacks by extraterrestrial creatures, and she was also dubbed the "Supreme Mage" by people.

As time passed, Ancient One began to look for new candidates for the Supreme Mage. There were many people with magical talents, but there were no people who could grow to the level of the Supreme Mage.

It wasn't until the age of fifty that Gu Yi began to worry because she never saw a suitable candidate appear.

At this time, she came into contact with black magic. There are decent magicians who protect the earth, and naturally there are also some villains who take the unconventional path and absorb the magical energy of the evil dimension to do evil.

On the way to annihilate these villain mages, Ancient One accidentally discovered Dormammu, a monarch from the dark dimension who made a living by devouring the universe.

His existence was recorded by the Ancient One as "multiverse level" in later magic books.

Once this kind of existence is fully fired, the earth cannot stop it at all.

Among the dangers, there are actually benefits. Ancient One discovered a spell that can absorb the power of Dormammu.

Normally, Gu Yi would not bother to absorb this kind of evil spirit's magical energy to enhance his own strength.

But the important thing is that she discovered that many of the mages who absorbed the power of Dormammu were aiming for immortality.

Therefore, the Ancient One began to have ideas about the power of Dormammu.

"I can absorb Dormammu's power to live forever, so that I can have more time to find a suitable candidate."

As soon as this idea appeared in Gu Yi's head, it spread uncontrollably.

But once this kind of thing spreads, it will cause a huge blow to the entire decent mage alliance.
