Kaecilius was astonished, "You want Kamar-Taj's magic?"
Andrew nodded, "Yes, Kamar-Taj's magic contains rules, and I'm very interested."
Andrew was very interested in Kamar-Taj's space magic; the rules it contained could accelerate his comprehension of the Space Stone.
"I'm willing to give you all my magic in exchange for five hundred years of life."
Kaecilius thought for a moment, then nodded in agreement. To be honest, he profited from this deal.
For a Demon Lord, five hundred years of life is nothing, but for a human, five hundred years is an incredibly long time.
"Very well, let's discuss the second deal."
Andrew took a sip of tea and asked, "Have you heard of Dormammu?"
"Of course, I have. Dormammu was once a mage. Later, he abandoned his physical body and merged with the Dark Dimension, becoming the Lord of Darkness."
Kaecilius nodded, "He has always wanted to devour our universe and is Kamar-Taj's great enemy."
"The Lord of Darkness can resurrect your wife and children in another form."
Andrew asked, "Are you interested in becoming the next Lord of Darkness...'s agent?"
"The next Lord of Darkness's agent?"
Kaecilius was first stunned, then reacted, "You want to become the Lord of Darkness?"
"I'm not really interested in becoming the Lord of Darkness, but Dormammu wants to devour our dimension, and he and I are destined to be enemies. To avoid being passive in the future, I need to strike first."
Andrew said, "Of course, getting rid of him isn't easy, Kaecilius. I want you to go and believe in him, and then, at a critical moment, stab him in the back."
"You want me to be an undercover agent?"
Kaecilius was a bit confused. He had never thought that he would have the chance to be James Bond in this life.
"Yes, you are the most suitable candidate."
Andrew nodded and said, "After it's done, you will become the agent of the Dark Dimension. By then, whether it's eternal life or resurrecting your wife and children, it won't be difficult for you.
Don't worry that Ancient One will have any objections. She'll be too happy to have this trouble with the Dark Dimension resolved.
Also, I will help you block the erosion of dark power, which means you won't become a dark believer."
Kaecilius was somewhat tempted. He asked, "Why am I the most suitable candidate?"
"Because Dormammu will actively seek you out and entice you to betray with Ancient One's secret."
Andrew said, "Dormammu certainly won't suspect someone he recruited himself."
Kaecilius recalled what that book said a while ago and was stunned, "Teacher's secret to eternal life?"
"It seems he has already approached you."
Andrew smiled, "It's not a big secret. The reason Ancient One can live forever is because she has been freeloading off the Dark Dimension's power."
"Teacher is absorbing the Dark Dimension's power?"
Kaecilius's eyes almost popped out. This isn't a big secret? If this gets out, the entire Kamar-Taj will collapse, won't it?
After the shock, Kaecilius shook his head repeatedly. He shouted loudly, "This is impossible! Teacher would never do anything against Kamar-Taj's principles. She has always taught us not to use dark power."
Andrew asked, "Why doesn't she let you use dark power?"
"Because dark power corrupts the heart, and using dark power comes with a price."
Kaecilius said, "Those dark entities are not philanthropists. While They give you power, They will take away your life, emotions, soul, or loved ones."
Andrew then asked, "Do you think Ancient One would be corrupted by darkness?"
Kaecilius answered without hesitation, "Of course not. How could mere dark power corrupt the Sorcerer Supreme?"
"So, the first problem isn't a problem. Let's talk about the second problem."
Andrew continued, "It's true that using dark power must come at a price, but Ancient One created an unprecedented freeloading magic that allows her to use the Dark Dimension's power at will, without paying any price.
In this situation, why can't she use dark power?"
"Freeloading magic?"
Kaecilius looked bewildered. How could such magic exist in this world? Also, isn't this even more outrageous, using someone else's power for free without paying?
Ancient One's tall image in Kaecilius's mind collapsed at this moment. However, although he was dissatisfied, confused, and even angry, it didn't reach the point of resentment. After all, in this life, Dormammu wasn't there to fan the flames.
"Why not use power that's free? What's more, she absorbed the Dark Dimension's power to protect Earth."
Andrew said, "Kaecilius, you should be ashamed. If it weren't for you useless disciples who couldn't shoulder the Sorcerer Supreme's position, why would Ancient One have to endure such hardship?
Working for hundreds of years continuously, do you think it's really that fun? Ancient One has long wanted to retire, but she can't because Earth needs her."
Kaecilius was speechless. After a moment, he said, "Teacher shouldn't have deceived us."
"Telling you would only increase unnecessary risks."
Andrew shook his head and said, "Actually, I've always wanted to learn this magic, but Ancient One probably won't teach me. Let's not talk about that, Kaecilius, are you willing to do this second deal?"
Kaecilius thought for a moment and said, "I want to go back to Kamar-Taj and ask Teacher first."
"Alright."
Andrew said, "Let's complete the first deal first. For the second deal, you can come find me anytime after you've thought it through."
"Okay."
Kaecilius nodded. Then, he exchanged the Kamar-Taj magic he knew for five hundred years of life from Andrew.
The transaction complete, Kaecilius immediately returned to Kamar-Taj. He had to get this matter clarified with Ancient One.
"Combat magic, space magic... Although there's no super-tier magic like Isaac Form, this deal is not a loss."
Andrew nodded. With his ability, he could learn these spells in a day and turn Them into his exclusive spells.
At Kamar-Taj, Kaecilius rushed to find Ancient One. Ancient One was elegantly drinking tea as usual. Kaecilius motioned for the others to leave, then he eagerly asked, "Teacher, you really freeloaded, no, you really are absorbing the Dark Dimension's power?"
"Freeloaded?"
Even Ancient One's hand stiffened for a moment. She said, "I am indeed absorbing the Dark Dimension's power, and I truly don't need to pay a price."
"So it's true."
Hearing Ancient One admit it herself, Kaecilius's emotions were extremely complex: dissatisfaction, anger, guilt, and also relief.
Since Teacher can 'adapt', then he can also adapt.
"Teacher."
Kaecilius exhaled and said, "The Demon Lord proposed a deal to me, and I'm prepared to accept it."
Ancient One asked, "What deal?"
"A deal to scheme against Dormammu."
Kaecilius did not hide anything. He said, "My lifelong dream is to resurrect my wife and children and achieve eternal life. The identity of the Lord of Darkness's agent can help me achieve these two dreams. Teacher, I know I've failed your teachings, but I truly want to resurrect Them."
