While Shen Mu was battling Mephisto, the Ancient One, on the other side, was also engaging her old rival, Dormammu.
As a Dimension Lord, Dormammu himself represented the entire Dark Dimension, and the Ancient One was currently located within the Dark Dimension.
"Dormammu, Earth is not for you to covet. Retreat at once."
After saying this, the Ancient One raised her hand, displaying the mage's symbol, the Crimson Bands of Cyttorak, and then unleashed several bolts of crimson Bolts of Balthakk. The terrifying lightning, with a rolling momentum, struck towards Dormammu, like a giant serpent twisting and turning.
Such conventional magic skills posed no threat to Dormammu. The magic Fire around him surged, instantly engulfing and incinerating them.
The Ancient One showed no surprise at this; after all, they had clashed several times before, and this was merely a test.
Dormammu, of course, showed no mercy.
With a thought, dark energy surged around him, and arrows of magic power flew towards the Ancient One.
The Ancient One, however, merely rotated her wrist, and a bright yellow magic circle appeared, deflecting all the magic arrows as if they were pulled by gravity.
Seeing this, Dormammu opened his massive mouth, and a terrifying energy ray shot out.
The Ancient One's finger twitched, and the magic circle in her hand suddenly stretched, causing the powerful defensive magic, the Ancient One's body of Hoggoth, to appear.
Dormammu continued to increase his energy output, gradually staining the bright yellow magic shield purple-black. Eventually, the magic shield in the Ancient One's hand shattered simultaneously with Dormammu's energy ray, transforming into a myriad of flying purple energy butterflies.
"Ancient One, this time Earth is doomed. Once Mephisto deals with that dragon, you will pay the price for stealing the power of my Dark Dimension!"
Dormammu, his entire body covered in black magic Fire, slowly contracted, gradually transforming into an approximately five-meter-tall dark flame energy creature, and then spoke to the seemingly short, yellow-robed bald mage in front of him.
This was Dormammu, the master of the Dark Dimension, and also the Ancient One's fated adversary.
Originally, Dormammu was just an ordinary mage, and his talent was not particularly outstanding. To gain greater power, he turned his attention to Dark magic.
While attempting to master a powerful forbidden magic, he accidentally discovered the ownerless Dark Dimension. Since he was the first living being to step into it, a broad path to becoming a Dimension Lord was laid directly before him.
Without hesitation, he abandoned his physical body and merged with the entire Dark Dimension, thereby gaining the dark power of the entire dimension, instantly becoming a powerful Dimension Demon God.
After becoming a Dimension Demon God, Dormammu, in order to gain even greater power, began to try and devour other Worlds.
It was at this time that the Ancient One, to prolong her life, began to draw power from the Dark Dimension. For him, the Dimension Lord, this was akin to having flesh carved from his body.
So, he followed the Ancient One's trail, thereby setting his sights on Earth, and thus began his repeated harassments of Earth.
However, every one of Dormammu's invasions ended in failure, because the Ancient One was immensely powerful herself, backed by a White Magic god like Vishanti, and wielded an artifact like the eye of agamotto.
And this time, Mephisto, another powerful Hell Lord, sought him out to invade Earth together, with the latter only wanting the body of a dragon.
This deal was extremely profitable for Dormammu, as he had always suffered from fighting alone.
Although he knew that a body coveted by an entity like Mephisto would not be simple, for him, who had completely merged with the Dark Dimension, even the most powerful body held no attraction.
Because his only way to grow stronger now was to continuously devour other dimensions; the stronger the Dark Dimension, the stronger he became.
"Dormammu, are you so certain Mephisto can defeat that dragon?"
The Ancient One, standing before Dormammu, spoke calmly, seemingly full of confidence in Shen Mu.
"Ancient One, you don't need to feign composure. With Mephisto descending in nearly his true form, no one on Earth can truly match him."
"However, to be honest, if you want to prolong your life, why not fully embrace the darkness? Your Vishanti cannot even grant you eternal life."
"Think about it, I was once just an ordinary mage, far inferior to you in talent and strength, but now, I am the immortal and indestructible master of the Dark Dimension. Powerful magic makes me eternal."
"Embrace the darkness with me!"
Dormammu knew he couldn't defeat the Ancient One, so he began to use words to tempt her.
Although he knew it was futile, all he needed to do this time was to stall the Ancient One and prevent her from assisting the dragon.
With Mephisto's power, it shouldn't take long to eliminate that dragon.
Then, with two Dimension Demon Gods acting together, even the Ancient One would be powerless to resist, and Earth would become his prey.
Unfortunately, he overestimated Mephisto and underestimated Shen Mu.
Outside, Mephisto at this moment found that things seemed to be a bit beyond his expectations; Shen Mu was completely fearless.
He was recklessly squeezing the potential of every cell in his body to gain immense power.
Mephisto, seeing this situation, couldn't sit still. After all, what he wanted was Shen Mu's complete and flawless body. If this body suffered permanent damage due to excessive extraction of potential, it would be a huge loss!
"Stop it!"
Mephisto now completely regarded Shen Mu's body as his own, appearing even more worried than Shen Mu himself.
However, the next moment, Mephisto was somewhat stunned!
Because he could feel a special energy within Shen Mu's body rapidly repairing the damage.
But before he could rejoice, Shen Mu's attack arrived again. The laser heat vision from his eyes, combined with the explosive breath from his mouth, transformed into a rolling torrent of energy that blasted Mephisto.
It continuously pushed Mephisto's body flying towards space.
Although supplemented by the divine power of the Talisman, Shen Mu's combat power was still somewhat reduced in an environment without the Sun.
And now, Shen Mu had decided to have the final showdown with Mephisto!
This forced Shen Mu to obtain even greater power in an extremely short amount of time.
And there was such a method: flying directly into the Sun, allowing the cells in his body to absorb radiation to an overload, but this was a suicidal method.
However, that was for the old Shen Mu, but now, with the power of the horse talisman and the dog talisman as a safeguard, Shen Mu could completely try this method.
He just needed to temporarily suppress the power of the horse talisman within his body, otherwise, as soon as an abnormality appeared in his body, the horse talisman would autonomously expel the excess energy from his body.
"Look, those two monsters are going outside of Earth. Are they going to leave Earth to fight in the Universe?"
And the people on Earth watching this battle, seeing such a scene, couldn't help but feel a glimmer of joy in their hearts.
