Jack followed the A.O(Ancient One) to kamataji where he spent time to train in all kind of sorcery either from the memory he copied from Loki or the training the A.O gave him to control his powers, and what I mean by powers is his energy, as for his physical strength it has already reached a level where the A.O didn't know a good method for him to train in it.
for Jack, he kept his overclocking state always open so that he could learn much faster, also his started unlocking the new abilities that he gained from the "golden sentry serum" like:
+ Molecular Manipulation: he could control all kind of matter at a molecule level he can literally disintegrate heart and erase it from existent, with a thought, he can also create anything he wants as long as he knows it structure from a cellular level making, he is sure that even if he met a strong being and in turn he turned him into ash, he can recreate his body.
at the same time he also started to notice that his weight is way, way heavier than "normal", he estimated that he was weighted more than 30 tons and this all brought by his cells density and his compressed muscles and bones.
also his brain evolved into a quantum brain, a 4 dimensional brain making his normal thinking like when he is in an overclocked state, and when his 4D brain activate his overclocked state he would be like 1000 of quantum computers working at the same time on the same problem if he wishes so, and this allowed him to learn all of kamatajis' magic knowledge and Lokis' in one week, he even went beyond as he started creating his own magic.
not only this, but he can also use telepathy to read, control, the mind. as for his other new abilities, there are:
+ Photokinesis: Jack also has the superhuman ability to generate, control, and emit light. This ability to produce hard-light constructs may be similar to those of Dazzler.
- Light Projection: Having absolute control over the light he produces, he can control its direction, frequency (color), amplitude (intensity), and duration. Jack can produce numerous effects with the light he manipulates. He can simply cause a bright glow all about his body. He can create a pulse of light on the order of several tens of thousands of lumens of power per second (the sun produces at most 10,000 lumens of brightness at noontime), which temporarily blinds people with its brilliance.
- Energy Blasts: Jack can generate light, heat, kinetic force, and other forms of energy as powerful blasts and explosions of a yellow color. These blasts are usually generated from the hands and eyes. The maximum power of these blasts is unknown. He can be sure that this ability is capable of burning Hulk's skin and leveling up a whole city. He can also emit omnidirectional blasts that were able to eliminate anything he wants.
+ Biokinesis: Jack can basically cure anything he wants from scratch to incurable diseases without the Horse Talisman and if he added the talisman power he can literally cure anything even if the person had a missing arm or leg. Hell, even if he has only half a body.
+ Resurrection: Jack can use his strong WILL to resurrect any dead being by calling the soul back, he first experimented on mice as he brought a group of mice to life after he killed them with a thought, but he was discovered by the A.O who was shocked but still explained to him that the resurrection he was doing is harmful to the balance as he was literally using his will to bring the soul back from the underworld, but he told him that if he wants to do it safely he needs to gain the approval of the law of death, life, and soul to make a safe resurrection, or else, if he continues to do it like this he may bring unforeseen damage to the person he wants to resurrect.
+ Power Sharing: Jack discovered that he can share some of his powers with people he wants, but Jack tried to merge this ability with his magic, and in terns, he created a strong magic that allows him to give anyone he wants any ability he can think of.
Jack also discovered that he can grow his body size from an ant to a giant with hundreds if not thousands of meters tall.

3 years later
As the training of Jack continues, the A.O was astonished that Jack can learn at such a high-speed everything he taught him and even create new magic based on his imagination, leaving the poor A.O feel like a dog who lived in vain, he even started having Ideas of making Jack the next supreme magician of Kamataji, but he dismissed it as he understands that Jack is only here to train.
Jack who had no idea that his training almost changed the fate of Dr. Strange, was happy as he finally created a magic seal after 6 years of hard work, this seal will limit his physical strength so that he can learn to control it slowly in time.
not only this, Jack also kept track of what is happening outside, especially Robert Reynolds the future Sentry, he is still a young boy, because when Jack arrived, it was already 1945 the end of the W.W II and according to his understanding Steve Roger became Captain America in 1941, and there is still more than 10 years before he becomes the Sentry and Jack won't stop him, because he wants to fight with him.
..........
next morning, the A.O went to Jacks' room, he knocked on the door, and said: "Jack come to the training field ".
inside the room there is a silver-haired handsome man with his eyes closed he floated in the air as he meditates, the moment heard his voice he opened his eyes, they flashed with a blinding light.
Jack stopped his meditation and disappeared the next moment. On the training field, the A.O was standing in the middle of it closing his eyes waiting for Jack. The next sec. he opened his eyes as he looked at Jack who appeared in front of him with a bitter look.
"Jack, you have already finished your training and you already have a simple control over your powers, now, I'm not asking you to leave but if you want to have higher achievements you have to see the world and experience different lives because your control over your powers start from your control over your emotion and life so, go outside and experience it"
Jack looked silently at the A.O, after a moment of silence he looked deeply and respectively at him as he said: "Thank you master for your teaching, I will do as you say"
As Jack finished his talk he teleported.
....
New York, 1948.
Jack appeared in a small alley, he walked out and started walking, he was really curious as this is the first time he had the chance to see a 1948 New York, he looked like a curious child at everything from cars to peoples, and as he did so did the people he bypass, because of his unusual clothes that made him look like a monk plus his handsome appearance, and his curious face made him look outside the normal.
Jack didn't care about them as he just kept staring everywhere. After he satisfied his curiosity, he changed his clothes to an old-fashioned suit and went to a restaurant to eat.
As Jack was eating he started thinking about his next move, he wants to integrate into this world and learn more about it, he especially wanted to get the ability of Owen Reece also known as Molecule Man, he is one of the strongest beings in the universe and he wants to copy or devour his ability to upgrade his control over molecules to a deeper level, apart from this he wanted to start his new hero career, and he won't be known as "Godfather", at least that is what he wants.
As Jack was thinking about his future plans he started hearing some strange screaming like a person who is screaming underwater, Jack tried to focus on these voices as they were many, and as he did that he was surprised to hear them coming from the ocean, Jack didn't delay anymore and he directly wore the new nano-suit that he created in his free time on kamataji using his abilities, in less than a second before anyone could notice anything Jack finished his food and put the money on the table as he runs to where the screaming is.
As Jack arrived he found a huge city underwater, a more advanced city, he felt like he returned to the 21st, but in a different way, but Jack didn't care anymore as he went directly to a palace where the screaming is heard, once he went in he found blue and white skinned people being killed by a group of mobsters, and a small group on the other side was fighting these mobsters, Jack had already identified who's the enemy as he went directly to the mobsters and nocked them out before they could even react, once he finished he looked at the other side who is looking at him with vigilance and astonishment, because Jack moved so fast knocking all the mobsters down before they could even react.
Jack looked at these Atlanteans' with curiosity especially a woman who and a man who stood out on the group. Jack felt that it started to get awkward as he kept staring at them, so he coughed and said: "Hi there, I'm sorry to intervene here but once I heard the scream from New York I 'run' hear to see what happened and I hope you don't take my action as an offense because I only wanted to help, and you don't have to be nervous because if I wanted to kill you no one can save, as you can see from these group of mobsters"
as they heard him everyone relaxed a little bit but no one made a move to even talk, as the atmosphere started getting colder a man who seemed the leader walked from the group, he looked handsome with dark hair and light black armor that cover only his shoulders, he said with gratitude: "thank you for your help human, my name is Namor McKenzie the prince of Atlantis, I hope you can come to join us in this celebration to thank you for what you did"
Jack nodded at him and said: "I am glad to meet you, Prince Namor, my name is Jack Ming I hope we can get along with each other"
the two shook their hands and laughed, as Namor wanted to bring Jack to sit on a seat he looked awkward at the mess the mobsters did which made him angry and embarrassed, he looked at Jack with an awkward smile: "I am sorry Mr. Jack but I think we may need to change location"
Jack looked at the mess then looked at the awkward Namor, he smiled and lifted his hand a light flashed and then everything started returning to its place like time-back, this strange scene choked everyone here, they all opened there mouth in surprise not only because of the destroyed building being 'repaired' but because everyone they saw dead started opening their eyes which and getting up, the only girl on the group started crying as she runs to one of the people who got up, hugging him and kissing him on his face, he looked old so Jack assumed that he was her father.
After everyone got up and understood the situation they looked at Jack with shock, awe, and respect, Namor who was equally shocked tried very hard to suppress his shock as he looked at Jack and said: "Thank you, Mr. Jack, thank you for saving my people" he shaky voice totally betrayed him, but no one blamed him or even care.
Jack smiled which made his devilishly handsome face more sunny as said: "No problem prince Namor, so shall we continue the celebration... Oh, by the way, what are you celebrating"
Namor did not dare to fart as he looked at Jack seriously: "Mr. Jack, please call Namor as I don't deserve the title of prince in front of you, as for the celebration it is Lord Thakorr birthday and the woman you see hugging him with the middle-aged man is his granddaughter and father who you r..revived him" Namor couldn't finish the last sentence as it was too absurd when even he saw it he couldn't help but tremble.
Jack said: "Oh, I didn't think you have a birthday party here, I hope you excuse me intruding as I also want to have some fun"
before Namor could say anything an old mans' voice said hurriedly: "No, no it is my honor to have you at my birthday party, please come let me introduce you to everyone, plz come with me"
Jack smiled at the old, he already knew which story is happening
