"That's the power of The Energy Book! It would be too much of a slack to just store it as a book. Feeling the energy in his body that he had never seen before, Casillas smiled wildly and happily.

The form pattern of the Book of Energy has increased his efficiency in extracting and using Dormammu's energy by an unknown number of times. If in the past, his efficiency was just a suction pipe, and he took some energy from the dark dimension without a mouthful, then at this moment, with the assistance of the form mode, he was equivalent to opening a water pipe in the dark dimension, continuously opening the sluice gate and draining water.

Generally speaking, such a huge influx of energy would make him unable to withstand the influx of energy and explode, after all, the energy of the dark dimension is indeed quite dangerous compared to the mages, and Dormammu, as the master of the dark dimension, will not think too much about wasting his strength to purify and filter his power for Casillas, so that they can borrow it more efficiently. Being able to open the permission to borrow Casillas is already based on the other party's face in handing over his soul and everything.

Of course, if it is the ancient one, Dormammu is still happy to pay more, and the conditions can also be discussed. After all, such a powerful disciple, placed in the dimensional demon gods, is also fragrant, worthy of the demon gods to devote themselves to cultivation, and even negotiate on the issue of treatment with a good voice. If the demon god is compared to the boss of the human world, the powerhouses in the monolithic universe such as Odin and the Ancient One are compared to employees. Have you ever seen an employee who can slap the table with the boss and the boss has to endure it? The Ancient One is of this level. The future Scarlet Witch can also be said to be of this level to some extent.

But Gu Yi obviously has no heart to take refuge in Dormammu, she has Emperor Weishan behind her, and there are many other spare tire options, Dormammu? Who's that?

Even if Dormammu took care of it, in terms of the energy extraction strength of the dark dimension, ten Casillas were not as good as one ancient one. But that was when he didn't equip the Book of Energy.

Now he has the Book of Energy to help him filter and purify, store and release the power of the dark dimension, like a valve, flexibly adjusting and providing the corresponding amount of energy according to his body and needs.

He can mobilize one by himself, but in Morphology mode, he can use the technology of the Energy Book to use it for ten points! The metaphor of the image is that Stark's combat effectiveness without wearing a steel suit is not high, but Stark's combat effectiveness wearing a Mark suit will be rapidly increased according to the technology of the Mark suit, and it will be effortless to be a hundred.

The various forms and patterns of the Book of Energy, for Casillas, are equivalent to Stark's various Mark suits. Well, self-adapting and compatible, self-upgrading drives all dimensions and transcendent versions.

Casillas now has the equivalent of an extra external energy source, he only needs to mobilize one part of the energy in his body, and the energy book will naturally help him make up for the other ones he wants.

Of course, because of a series of programs such as self-adaptation, upgrading, filtration, purification, perception, etc., it is understandable that a considerable proportion of the extracted energy will be lost when it is supplied to the user.

At least Casillas understands well. He is not a low-level mage who doesn't understand anything, even if the ancient one wants to use the power of the dark dimension, he needs to filter the erosion of the dark power and other attributes that affect and distort the user's mental consciousness, as well as the due loss of the burden in the process of transforming into pure magical energy used by the mage.

So even if the loss rate of the Energy Book is a little beyond the standard, Casillas only considers that this is the price it deserves. After all, it is necessary to drive the use of the energy book to drive the supply, isn't it? The Lord's dimensional power is as majestic and vast as the sea, and the little he consumes is at most a small insignificant wave in the sea.

But this consumption can make his strength quickly climb to the point where he can compete with Gu Yi. In particular, morphological patterns have all sorts of magical effects.

The huge array shrouded the entire suspended platform, and the power of all alien dimensions within the array would be limited and reduced, and only through the energy book behind him that the energy was continuously stored and transformed would not be affected.

Transparent like ice, the irregularly shaped spatial blade emerged from Casillas's hand, in the form mode of the Book of Energy, he had already found that the power of the surrounding dimensions and the magical energy in the body of the ancient one mage were decaying rapidly, he rushed towards the ancient one, and the spatial blade in his hand stabbed the ancient one's body viciously.

The brilliance of the magic collision splashed on the platform, and the two figures went back and forth fiercely in a dangerous battle, and the ancient one seemed to be really affected, retreating under Casillas's attack, not only could not maintain the earlier suppression of Casillas, but in turn there were signs of being suppressed by Casillas.

A surging force of magic burst out between the two, and Casillas, who bore the brunt of the blow, staggered back two steps again, but quickly gained a foothold. For his second miss, this time he showed a lot of calmness, and even had a look of surprise.

"It seems that you have realized that in this forbidden demon realm, your magic energy will only be used less and less, no matter how careful you are, how long can that energy support you? You should die, Supreme Mage. Casillas' gloomy and gloomy face added a chill to his words. He wanted to see from Gu Yi's face that she showed emotions such as fear, fear, or despair in the face of death, but he carefully observed for a few seconds, but he could only see Gu Yi's unwavering, unchanged calm.

Casillas rushed forward with the spatial blade again, this time far more fierce and brave than before, as he found that his current magic resistance and defense were terrifying, and he had a steady stream of energy to repair his damaged body with magic. On the contrary, the Ancient One Mage will only become weaker and weaker within the Forbidden Demon Realm. It's like a fish that has landed on the shore, if it can't get back into the water quickly, it can only struggle to face death weakly.

Casillas's current plan is to exchange injuries for injuries with the ancient one as much as possible, frantically consuming her remaining energy and physical strength, and time is on his side!

And the development of the battle also confirmed his idea little by little. The ancient one is getting weaker and weaker, in the past, he could often cause some injuries to him in just a few strokes, and even staggered to throw him out, but as time goes by, the other party is now entangled with him for longer and longer times in a round, and the energy in his body is somewhat unsustainable.

Casillas even sensed that the mirrored space of the ancient one was trembling slightly, and the surrounding platforms were constantly collapsing, and the whole space looked like it was about to fall into the apocalypse, showing a sense of dilapidation.

All of this shows that the energy of the Ancient One is on the verge of being exhausted, and even the mirror space is unable to maintain it.

Casillas was overjoyed in his heart, and increased his attack, all kinds of magic combined with the spatial blade in his hand to attack the ancient one, consuming the other party, and at the same time, he also saw the opportunity and stabbed the ancient one's heart.

The near-transparent spatial blade cut through all obstacles, inflicting a fatal wound on the Ancient One's heart, and under Casillas' ecstatic gaze, the mirror space sped up to collapse. Soon, as the Ancient One's aura became weaker and weaker, they were able to use the portal to break free from the shackles of mirror space and reappear outside the church where they were hiding.

At this time, swirling sparks flashed from all around, and Casillas and his remaining companions saw that the situation was not good, and immediately opened the portal and got in.

When Mordo and the Mage King came over with their men, all they saw was the figure of Casillas and the others who had entered the portal and left, as well as the Ancient One who had fallen in a pool of blood.

This scene shocked their minds so much that they did not stop Casillas from leaving. They were taken aback by the sudden death of the Ancient One.

In their concept, the ancient one is omnipotent and invincible! She is the strongest of all mages, and she is a powerful character who has a headache for most dimensional demon gods, and her existence is equivalent to the supreme mage itself, and it can be said that she is the spiritual pillar of all mages now! For the mages, no matter how bad things happen, as long as the Ancient One is still around, they will always have faith.

They never thought that they would see the death of the Ancient One! The impact of this scene is as unacceptable as believers seeing their gods being killed in front of the infidels.

……

Silent City.

"Are you okay like this? They still don't seem to be able to accept your death. What was replayed in front of Luke was the expression of the mage king and others surrounding the body of the ancient one, panicked and not knowing what to do.

"They'll always take it. I've been in charge long enough that it's time for the next Supreme Mage. Ancient One's voice suddenly rang out from Luke's side. The Ancient One Mage in the soul state floated to Luke's left side, and looked at the projected picture with him, and said with a calm expression.

"Do you need me to make you a new body?" Luke looked sideways at the soul-like Ancient One.

"No, I can always condense a new body if I need to. The rest should not be my responsibility. Gu Yi is quite free and easy, and it is obvious that she said to let go, that is, to let go completely and unreservedly.

"Then you can go to the Energy Bank, I'm sure Mephisto will be glad to see you there." Luke smiled meaningfully.

"I'm afraid he won't welcome me, but will think that I used to steal power with him." Gu Yi shrugged his shoulders indifferently. Anyway, according to her plan, she will not be resident in the Energy Bank, but will only be responsible for some dimensional affairs. What Mephisto thinks is none of her business.

"The rest really doesn't need me to come forward? Don't need to say goodbye to them or anything? Luke looked at the picture again.

"No, you can tell them when the matter is settled." Gu Yi shook his head, "If it goes well over there later, I'll still have to deal with Dormammu." ”

"Don't worry, haven't you already figured out the most suitable future through the Eye of Agomoto? With step-by-step development, what should happen, will naturally happen. Luke felt the trail of the Book of Energy and whispered.

"Peeking into the future is not a panacea, especially if there is a powerful force in between. In the face of the Dimensional Demon God, how much the power of time can take effect, no one can really be sure. "Ancient one. As an artifact of the Supreme Mage, the Eye of Agamotto should never leave her body, just like Odin's Gangneel and Thor's Mjolnir, but this time she never used the power of time from beginning to end, and even the Eye of Agamotto, which never left her, was lost in Kama Taj. After she decided to step down, it was already a treasure she left to the next Supreme Mage.

……

The door of the Holy of Holies in New York was violently pushed open from the outside, and Casillas, who was still in the Aslan form, strode in with his hands.

In addition to support, as soon as the remaining mages stood up, Casillas used the power of forbidden magic to seal the circulation of energy, and then used the space blade and magic to solve each other.

"We don't have much time, and after destroying the Nexus of Enchantments, we must leave before they get back and destroy at least one of the other enchantments." Casillas shook off the mage's blood stained on the spatial blade and dispersed the forbidden realm, commanding his mages.

Following Casillas, several mages who were deeply eroded by Dormammu's power and whose souls were no longer able to escape from the dark dimension immediately walked towards the hub of the enchantment, and under the magical knowledge instilled by Dormammu's violence, they knew how to destroy and stop the operation of the enchantment.

Soon, one of the three impregnable enchantments began to flicker, as if it had been in poor contact. However, because of the Trinity, when the three major enchantments are connected and supported by each other, the destroyed enchantments can still exist for a while. During this time, it can be quickly restored to normal if it undergoes emergency maintenance and repairs.

But Casillas knew that if he broke one more, the fragility of the barrier would not stop the long-awaited Dormammu from breaking in. He only needs to break any of the other enchantments now to usher in his Lord. At that time, even if the ancient one is resurrected, it will be useless to face Dormammu. All human beings will be able to enjoy eternal life under the power of Dormammu.

"Quick, don't get tangled with them." Sensing a new wave of magic teleportation nearby, the mage king who rushed back walked out of the open portal, and Casillas rushed to the sanctum sanctuary of the next enchantment without looking back.
