The reason Stark was here all started from a few hours ago when Adam hastily came to find Shiller.
Adam, after being abused by the Iron Demon God, King of Brightness, and Goddess of Glory together, finally gave in and was penned in. Don't forget, there were not only familiar faces from the cosmos among the onlookers at that time, but also Annihilators and Ravenous from the Antimatter Universe.
Because of the existence of The Sanctum, Dimensional Demon Gods in the cosmos are quite familiar with each other. After all, they often gather together based on human concepts of time, receiving gifts as members. For Dimensional Demon Gods who live such long lives, it's like stewing in the same pot every day, familiarity is unavoidable.
So, these two suddenly appearing strangers caught everyone's attention. At this time, the Annihilator and the Ravenous were planning to sneakily lure Galactus somewhere else and capture him.
Usually, Galactus, who is in a state of extreme hunger, needs the guidance of the Star-swallower Envoy to move. Galactus is highly intelligent, on a scale of nine or even ten, so as long as they captured the Star-swallower Envoy, they could definitely lure Galactus into a trap.
But in this universe, three Demon Gods chased a higher-level being across the cosmos, not knowing how many planets have been destroyed in the process. Galactus seemed to be here to break up the fight but, in reality, it was he who started dinner even earlier than the Dimensional Demon Gods.
Although Galactus is inherently deficient, and always ravenous, with no sense of reason once hungry, after a big meal, he has a moment of clarity. When he saw two sneaky figures running towards him, how could he not know what they were up to?
But, Galactus was momentarily unsure whether to resist or flee. After all, he was brought here by the guide of Infinity, who was currently managing the cosmos, to mediate the disputes. Infinity knew that this crowd would definitely cause a lot of damage. Instead of wasting energy to repair, why not feed Galactus all at once and expect him to play some role?
Now, the people originally engaged in the fight had stopped, and swallowing these two insignificant things held no interest. He decided to take advantage of his remaining strength to consume the wreckage in the surrounding area while he could, not wasting his title as the cosmic janitor. This thought crossed Galactus's mind as he decided to ignore the Annihilator and the Ravenous, turning his head and leaving.
But their main target was Galactus and the Annihilator, who had been in the Antimatter Universe for many years, didn't have much understanding of Material Universes like this one. They only felt that Galactus, although one of the supporting Gods of the cosmos, didn't have strong power. With a quick fight, they could easily capture him, right?
Thinking this way, the Annihilator and the Ravenous lunged towards Galactus together. Galactus, indeed, wasn't easygoing. He also wanted to fight these two annoying pests.
But his nature was driven by hunger. This universe had just been plowed over by a few fighting gods, making it a feast for Galactus. It's like asking a hungry man who hasn't eaten in seven days to stand on a pile of steaks. Who could resist diving in to eat, eat, eat?
Galactus turned his head and ran, yet his sufficiently clear mind allowed him to think of a way to trouble these two. He finally bellowed, "There are foreign Demon Gods trying to kill me! There are foreign Demon Gods here, not from this universe! They want to kill me!"
The Dimensional Demon Gods were still around, having just finished watching the fight. Upon hearing Galactus's words, they immediately focused their attention on the Annihilator and the Ravenous.
After several years of militarization training in The Sanctum, all the Demon Gods in this universe have been fully trained. If something happens anywhere in the cosmos, they will instantly pack up and be ready for departure, able to sing the song "Goodbye Mom, I'm Setting Sail Tonight" twenty times in three seconds.
So, within just a few short hours of Stark and their battle, most of the Demon Gods from all over the universe gathered here. It wasn't just one or two, or even one or two hundred Demon Gods, but thousands of hungry wolves lurking in various dimensions.
Galactus, who had deliberately lured enemies, disappeared in the blink of an eye. The only things left were the Annihilator and the Ravenous, now seeing an endless cosmos behind them filled with pair after pair of greedy eyes.
They, of course, heard Galactus's final call. Originally, Adam had disappeared and Thor had vented his anger, and the three were preparing to disperse. But Galactus's shout made Stark reconsider.
"Wait, don't go yet!" Stark stopped Thor and Loki, looked around, and said to them, "You know that big guy just now was Galactus, right? About him, I have a plan..."
Earlier, Shiller had transferred the soul of the Cancer Universe Galactus into his own brain. Although Eternity rebooted the universe, he didn't dare to reboot Shiller, so the spirit of the Cancer Universe Star-devouring Engine naturally ended up with Shiller, who later gave it to Stark.
At that time, Batman's mind was still in Stark's head. The limited time and valuable research material fully stimulated the research potential of these two most genius scientists in the universe.
Batman knew he couldn't take this thing with him, at least not at present. So he, of course, seized this precious opportunity as much as possible to research it. Stark knew that Batman would leave sooner or later, although he didn't say it, but he truly cherished the opportunity to collaborate in research with another super genius.
In this way, the two of them researched the structure of the Cancer Universe Star-devouring Engine deeply and quickly, in a manner that is unimaginable for people, even gods.
The results they came up with were even more astonishing. Batman didn't take anything from this universe. He just deeply imprinted all the research data of the Star-devouring Engine into his mind.
As a result, not long after he returned to the DC Universe, he deduced half the life equation out of thin air.
Those who were familiar with Darkseid would know that the Life Equation and Anti-Life Equation could be described as the frames of code of the universe. These things were not something that the human race could understand and take advantage of, let alone deduce them out of nowhere.
Apart from the beneficial effects Batman gained because he was the 'favored child' of DC, his research on the Star Devouring Engine was also invaluable. This showcases how much they had gleaned from that period of study.
And what Iron Man got was no less than what Batman got. Although he didn't deduce any cosmic formulas, he had the advantage of fighting on home ground. His research even surpassed Batman's in depth.
As mentioned before, the real reason Iron Man invited Batman to do research in his mind was that Stark had set a super challenging task for himself – it was to alter the cosmic constants.
The thinking of a top student is - if my answer is wrong, it's not because I'm wrong, but because the question is wrong. Being held back by material science, Stark firmly believed that it was not his material but the world that was wrong.
During the study of the Star Devouring Engine, Stark embraced the same idea throughout, and as a result, he really discovered a bit of a trick.
Humans truly can't change cosmic constants, just a low-level life, humans have no relationship with the rules, and even observing is very difficult, let alone directly changing.
But in theory, as long as humans can persuade a being that can change cosmic constants to change the constant, it can also be considered that humanity can change the cosmic constant.
Then someone may ask, why would a god who can modify cosmic constants be willing to help humans to do so? For this answer, please see Shiller.
Of course, Stark had neither the interest nor the patience to threaten the gods with a huge furball. Straightforward as always, the thinking of the Iron Man Demon God convinces others physically. Knocking out a god with a hammer, treating him like a mecha, stepping into it to control and change constants are also the same.
Since becoming the Iron Demon God, every time Stark picked up a hammer, everyone looked like a nail. His brain was full of wisdom; anyone could be a mecha that could be started, including Galactus.
The Star Devouring Engine was also an engine, like a galaxy is a river. As long as it is an engine, it belongs to the Iron Demon God. Galactus fainted in hunger. Why not take him home and transform him into a mecha, wrap it up in breadcrumbs, and deep-fry it golden brown? Even the Iron Man next door was drooling.
Sure, Stark holds the soul of a Star Devouring Engine in place, but the problem is that it comes from another universe. The swords of the previous dynasty can't kill the officials of this dynasty. Although the engine has the same effect and can be activated, it can't change the constants of this universe.
Why wait for a good day when you coincidentally encounter the planet devourer of this universe? Isn't this a good time for a crash course?
Stark explained his thinking to Thor and Loki, Thor thought Stark was too radical, and Loki thought Stark was too conservative.
Thor thought that Stark's tactic of rushing up to punch Galactus was too crude. Instead, he should ride on the face of the Rainbow Bridge directly, wrapping the ship with divine power, and knock Galactus unconscious in one shot.
Loki thought that transforming Galactus into a mecha was too cliché, and it was troublesome to put on and off every time. It was better to break his power completely, every person has a set of Admin Systems, with the ability to change code at any time.
Stark thought both of their suggestions made sense. The three of them thought for a while, and thought that how to deal with it was secondary. They had to hurry up and chase Galactus to prevent him from getting away. After catching up, they could go dual action mode. The Iron Demon God charges up to hold him, and Thor knocks him unconscious.
The Galactus who is eating has no brains, which is the reason for the sacrificial ceremony every time a large event is imminent. As long as they were characters with names, they could set up a trap and use Galactus's hunger to lure him into the trap, then twist him into a mess.
While Galactus was thoroughly enjoying his meal in the cosmos, Stark transformed into the Iron Demon God Engine with maximum system output. After rushing up at a lightning speed, he sent a hook punch, immediately followed by a punch from the top down. Galactus was suppressed before he could react.
Thor, like every Asgardian, let out a war cry after he saw the target was under control, followed by a divine charge, a whirlwind slash, and then three punches "bang! bang! bang!". Before Galactus could swallow his food, he was pounded by two Strongmen from the Nine Major Kingdoms, each weighing over 200 jin, and he didn't know where he was.
After Galactus was under control, Thor and Loki hurriedly used divine power to build a cage for him. In the meantime, Stark excitedly went through the Luminous Alliance's Base of Dreamland to Shiller's Tower of Thought and began knocking at his door.
He didn't come looking for Shiller to ask about the next plan, he purely came to tell Shiller some good news -
If he could alter the constants of the universe from the rule layer, could he easily remove Shiller's loneliness from the document, just like removing a line of text?
