The powerful, almost explosive energy that filled Shin's body quickly began to transform his physical form.
The energy from the Chakra Fruit could actually be considered gentle; the Otsutsuki clan had refined it for so many years that they had clearly maximized its energy properties.
However, no matter how gentle the energy, if there was too much of it, it couldn't be endured! While the energy was transforming his body, Shin felt that his so-called'steel body' was like a fake, completely collapsing under the energy's surge, then being reborn, only to be destroyed again.
A rushing sound emanated from his body; it was the sound of energy flowing within him. Terrifying energy fluctuations continuously spread through the void. It was fortunate that there was no matter left in this universe; if this were Earth, the energy fluctuations alone would be enough to pulverize the entire planet.
"Ah ah ah ah ah ah!" Under intense pain, Shin roared skyward, his terrifying voice causing ripples in the void itself.
Fortunately, Shin's self-evolution ability played a huge role this time. Amidst this destruction and rebirth, his self-evolution ability developed rapidly, evolving more perfectly each time than the last. In a short period, it achieved a level of evolution more terrifying than what would normally take hundreds of years.
It could be said that this ability was originally meant for those with tenacious vitality; each time they struggled back from the brink of death, their abilities in all aspects would improve, much like the Saiyans, the cosmic cockroaches.
In the original work, Doctor Doom, after lying low for hundreds of years, could only evolve to that extent. If his experiences had been as arduous as Wolverine's, he might have evolved into an Omega-level mutant.
With the continuous activation of his self-evolution ability, coupled with the inherent transformative power of chakra, Shin's body quickly began to accommodate these energies.
Feeling the immensely powerful energy within him, and a physique at least dozens of times stronger than before, Shin gently inhaled and then casually exhaled, his terrifying breath transforming into a cosmic storm.
"I've become so much stronger..." He stretched out his hand, and dark energy gradually spread. The Dark Hole, which could originally only expand to about a dozen times the size of Earth, now expanded to an incredible extent, gradually beginning to absorb the Divine Tree, which had already transformed into an alternate dimension.
When Shin used the Tesseract, he had left a contingency. The Divine Tree was transformed into an alternate dimension, almost like a World Tree, which could serve as the pillar for the dark dimension within his body, increasing the power of his Dark-Dark Fruit.
Under continuous absorption, the original dark dimension also continuously expanded. Furthermore, in the empty dark dimension, land, stars, and even the shape of a World Tree gradually appeared, with each leaf being a tiny world.
Unfortunately, the entire dark dimension was still very small, with a few scattered points of starlight, making it impossible for life to truly emerge.
Shin still wanted to test whether life born in his dark dimension would die if it went to other worlds! It seemed he was still a hundred and eight thousand miles away from reaching the realm of creating life.
It took several months, like an ant swallowing an elephant, for Shin to finally absorb the Divine Tree's alternate dimension, which was almost dozens of light-years tall. At the same time, the dark dimension within his body also expanded significantly. Now, he could jokingly call himself a lord of the universe.
It was also fortunate that the more he devoured, the larger the range of the Dark Hole became. Under this exponential growth, Shin was able to completely swallow this alternate dimension.
The growth of the dark dimension was not very significant for Shin now, but his Dark-Dark Fruit ability had indeed increased by an unknown number of times. With a wave of his hand, creating a real black hole was no longer a difficult task.
However, with his current Kryptonian physique, the Dark-Dark Fruit still lagged a bit behind.
If the Devil Fruit's ability was only slightly behind, then his chakra abilities had suddenly skyrocketed.
To put it simply, the Infinite Tsukuyomi, which previously required the Cosmic Control Rod to cast, was now effortless for Shin. Even if its range were to expand by dozens or hundreds of times, it would absolutely not be his limit.
The Five Elemental Ninjutsu had become so powerful that they were almost at a genesis level. Shin could now even use chakra to flick planets around like marbles.
If he used offensive ninjutsu with full power, its destructive range could even be measured in light-years! He could create incredible seas of fire, lightning pools, and storms, maintaining them almost semi-permanently, not dissipating for hundreds of millions of years.
The temperature of his Fire Release approached the sun's core, his Ice Release approached absolute zero, his Earth Release could easily create black hole celestial bodies, and his Wind Release could form spatial storms in cosmic space that could shatter an entire star system into dust... The chakra system, at this point, once again became Shin's primary combat system, powerful enough to rival, or even surpass, his multi-evolved Superman physique. It was so incredibly strong it was practically limitless.
Even the Otsutsuki clan, seeing the chakra within Shin now, would probably be blinded!
It was too powerful, incredibly powerful. It was almost like compressing a universe into a human body. Shin estimated that if he were to run out into the void and self-detonate, he would likely form a small universe, or rather, a world.
Although it certainly wouldn't form a multiverse like Marvel's, and even a somewhat normal universe would probably be a struggle, forming a universe roughly the size of a supercluster was no problem.
"I never thought the potential of the chakra system could be this strong." Shin clenched his fist. If not for his self-evolution, which allowed his Superman body to evolve many times while absorbing the Chakra Fruit, his current physical body would definitely not match his current chakra volume.
In that case, in a sense, he would probably revert to being like the original ninjas, with powerful chakra but a fragile body.
However, even that relatively fragile body, compared to his chakra, would still be strong enough to blind people.
He surveyed his surroundings. The entire Negative Zone was now completely finished. Aside from the void, there was probably not even a single atom of matter left in this universe. Shin could even feel the entire spatial structure becoming incredibly fragile, a sign that this cosmic space was completely heading towards destruction.
