Training

As time passe Jack started having control over his powers and because he kept his quantum brain activated he started realizing the truth about his divine powers and in this process, he could use it to intervene with the law that governs the Universe, but not in a large scale, but he understands that if he wants to do it in large scales he need to be a multiversal being capable of wiping out at least a universe.

Whis who was training Jack was shocked by the progress he made but he didn't show it on his face, but he can be sure that Jack has basically surpassed Beerus-sama and for this, he decided to teach him Ultra Instinct that allows the users to automatically react to any threat without the need to acknowledge it and defend themselves.

Their body can also move and adapt while in battle on its own, allowing them to attack and defend simultaneously without thinking.

However, this ability is not an absolute guarantee against all danger because if there is no genuine danger to his being as they were such obscure threats then the sub-conscience mind will not see it as life-threatening. Additionally, it does not make one completely aware of their surroundings to the point that they can avoid specific hazards, even relatively harmless ones, which is exemplified humorously by Whis when he steps in poop while explaining the technique to Goku and Vegeta.

Jack who was training stopped because Whis called him, once he understood that Whis wanted to teach him Ultra Instinct, he only smiled because he already has a quantum brain and his reaction is faster than the speed of light, but he still agreed to learn it, because he won't keep his quantum brain active all the time for a simple reason, and that is, once he does so, he will lose his emotions to better control and have advance calculation, this is not what he wants, he doesn't want to be a machine, so Ultra Instinct is good to learn.

3 month passed,

under Jack hyper state, he grasped the most basic Ultra instinct, to be exact only the tip of the iceberg, he can predict if someone wants to hurt him, but only the most basic, Jack can be sure that this is like when Spider-man uses his spider senses, so he understands one thing and that is Ultra Instinct is related to the six sense of the human body, so the only way to make it stronger is either by practice or learn a special cultivation method(oth: hhh, Saint Seiya is coming soon)

Whis is now holding a pudding while watching Jack training with heavy equipment reinforced by a gravity device on the max.

........

2 years passed,

Jack was sparing with Whis and in the process of these 2 years he told him about his 12 abilities, but he didn't disclose what they are, only told him their uses so that he can have better understanding and control over them, and Whis really did not disappoint him, he completely changed him either spiritually or physically, Jack also wondered why he couldn't transform into an SSj, but after a lot of meditation he understand that the energy he control is an advanced energy that is way ahead the 'ki'

used by other creature, just like the Hakai used by Beerus, so to say Jack may or may not be able to transform (oth: hmmm, well, it depend on what the readers want).

For Beerus Hakai, Jack was really gonna copy it in these years but when he thought about he didn't want to at the moment because he first wants to control his powers and in these 2 years he did it, he knows just waiting for Whis to go on a small trip to earth so that he can start his plan.

Whis: "Jack are you coming with me to earth to taste their food"

Jack: "oh, no it's ok, you can go ahead I will stay and train more"

Whis glanced at Jack then smiled: "as you wish, just don't wake up Beerus-sama or you may get into trouble"

Jack laughed: "please master Whis don't make these kinds of jokes I'm still too young to die"

Whis shrugged his shoulder as he took his scepter and taped it on the ground, a colorful light enveloped him and Whis disappeared from Jack's sight.

Jack sighed with relief and looked at the direction of Beerus and smiled, Jack walked slowly tell he arrived in front of Beerus room he activated his C.S, once he did he scanned Beerus and copied his Hakai, the moment he did it Jack returned to the training field, he sat in loutus position and started inspecting his body, as he did so he found a purple infinite energy residing in his lower dantian, Jack closed his eyes and used his spiritual energy to see what is happening, once he did so he found an amazing change started taking place in his cells, all his divine energy started changing or to be exact evolving, it devoured every shred of the Hakai Energy his lower dantian sent, and what is weird is that the purple energy that resides there seem inexhaustible, not only this he found that it has the same characteristic that the space stone have, thinking for a moment he comes to a conclusion that the Hakai is a law that tends to destruction, everything it touches will seize to exist, and his divine energy is absorbing this law, making it more violent yet harmless at the same time, of course, harmless only for him, this happened not only to Hakai but also to the space stone, he gained more contol and othoraty over it, Jack is really wandering, what would happen when he collects the six inifinity stones, would the inifinity appear infront of him? these are the question that Jack can answer after he collects all of them.

never mind back to Jack's cells, as his cells kept absorbing the Hakai they started going out of control, but just as they started in Jack soul the tiger talisman started shining brightly, as it started balancing the energy in his body to reach perfect harmony, Jack who was closing his eyed didn't know that the moment he started scanning Beerus, the later started waking up from it, and this proves how scary Ultra Instinct is, and this is not even the complete one.

Beerus who started waking felt a familiar energy signal coming not far from him, he yawned as he started concentrating on these signals, and the more he did so the more he got serious until he completely woke up.

Beerus: "now, who is that man? and where is Whis? doesn't he know that it is forbidding for mortals to come here" as he said that he looked at the direction of Jack?
