After thinking for a long time, Jack found a way to combine his unlimited physical potential with another power that could enable him to have 100 tons of strength in 3 years, allowing him to solve various problems he had.
But this would cost billions of FP to be what he wanted. Fortunately, in abilities that involve potential, he could buy only a much weaker version of this ability. Therefore, Jack wanted to wait until he left the Negative Zone to buy this ability and thus have as much as possible.
"System, I want to buy unlimited magic potential with the FP I have. I want to see what I can create after buying this potential," said Jack.
[Your FP is not enough to buy unlimited magic potential.]
Hearing this, Jack was shocked. He wanted to buy this ability with 2 million FP and heard that it was not enough. He understood that he could become a god with it and use magic outside the Marvel multiverse, which is why he wanted to buy it now.
But even with over 190 million FP, he could not buy this ability. This showed that even though he had reached a high level of magic compared to Doctor Strange, he still did not have enough to have unlimited magic potential.
"System, why can't I buy unlimited magic potential? I have a power close to Doctor Strange's, which can fight Dimension Gods. I should be able to buy the potential to become a weaker god," said Jack.
[It seems you did not understand when you asked the first time. The kind of god you can become by buying unlimited magic potential is not a weak god, but rather a god capable of easily destroying the entire multiverse.]
[With unlimited potential, you can learn how to use time magic, space magic, reality-altering magic, and even learn to create life with magic in just a few years.]
Upon hearing this, Jack was shocked and finally understood how shocking unlimited potential for magic was. After all, if he could learn to do all of this without anyone teaching him, he could easily create spells to destroy weak gods and the Marvel multiverse.
He could remember some anime characters who had such magical power, but he thought that this was more of divine power than magic. But at least he was excited knowing that this could be possible.
Certainly, such a nearly divine power would cost billions of FP, but Jack knew how to achieve this level of power more cheaply. When he increased his strength with unlimited physical potential to over 200 tons, this magical potential would cost less than 1 billion FP.
Jack could buy jutsus or Chakra elements that would make him a little stronger. Perhaps he could buy the jutsu and experience to unlock the Eight Inner Gates, but the system said that without greatly increasing his regeneration and resistance, Jack would die just by opening the fourth gate.
After all, Jack's current body strength is several times stronger than Rock Lee's body without using the Inner Gates, and the Chakra used to increase strength is thousands of times greater than Rock Lee's.
Even so, Naruto characters wouldn't be able to hurt the Hulk much before they died using the Eight Inner Gate, Jack needed to use the fourth gate to attack the Hulk with the same force and his muscles and bones would break.
That's why Jack didn't want to use this suicidal technique unless it was necessary or until he significantly increased his regenerative capacity. With a strength of 100 tons, he would have a very high regeneration and could even use the seventh gate without dying and thus could even hurt the Hulk.
"System, I want to use all my FP to buy the power to absorb any type of energy permanently to increase my strength and be immune to that energy. I want this power to be able to absorb the power of radiation, the power coming from the sun, cosmic power, and especially the power of the Infinity Stones," said Jack.
Jack had been thinking about this power for months and had improved the idea in the last few days. With his over 190 million FP, Jack knew he couldn't absorb a lot of power from the sun, cosmic energy, or the Infinity Stones, but this power had excellent synergy with his unlimited physical potential.
With this power, Jack wouldn't be immune to all types of attacks, he would only be immune to the powers he absorbed that indirectly attacked him. But this would allow him to survive in space and the Negative Zone without dying.
The main benefit of this power was that with it, Jack could possess the Infinity Stones without being killed by them and could even absorb a small amount of their energy. Even a small amount of energy from an Infinity Stone would be enormous for him to absorb.
The power to absorb energy from the sun was a weak copy of Superman's power, but if he could absorb a few various types of energy, he could increase his strength much more quickly than through training.
This time the system took a while to respond to Jack, as it seemed to be calculating how much power he could absorb with over 190 million FP. Although it would be little, it was a start, and since it was a type of potential, it wouldn't cost billions of FP, even if it could turn him into a god someday.
[The system praises your creativity and imagination. This power can be created. It won't absorb much power since it's permanent, but it will combine well with your unlimited physical potential and make you immune to the Infinity Stones as long as someone doesn't use them to attack you directly,] the system finally responded.
Jack immediately agreed to spend all his FP. He knew he could earn more FP over time, and he was greedy for the unlimited magical potential he could have soon. With this power, Jack knew he could face Thanos in a few years.
Soon, Jack felt an intense heat in his body, and his body glowed again as it hadn't done in a long time. Jack could sense, with his magical capacity, that various types of energy were slowly entering his body.
[As you know, this power won't make you resistant to any type of energy attack. You're only immune to passive energy. The closer you are to a large body of energy, the more energy you can absorb,] the system warned.
There is a power stolen from the MC, I said that his initial power would not be discarded, the initial power he bought was cheap because it was just potential, but he may have to use billions of FP to get stronger even through that power and from others and also from other things in the Marvel universe like the infinity stones.
