Superman in Marvel: Practicing Devouring Techniques, Unrivaled in the Universe

Marvel Universe.

Stark Mansion in Los Angeles.

"Didi di di di!!!"

As soon as Leon appeared in the basement, all the instruments and lights turned red and the alarm bells rang as quickly as if urging his life.

Daidai held the disinfectant spray, rolled over on a roller coaster and sprayed it at him.

Benben raised the fire spray on the other side, also ready to go.

"That's enough! Stop! Am I a burglar? Why are you making such a big fuss?"

Leon waved his hands at Benben.

The alarm bells and red lights finally stopped.

"Master, you are finally back. It seems that you are not having a good time in the other world." Jarvis' voice appeared.

"Finally? How long have I been away? It must have been more than ten years."

Lyon's heart skipped a beat. If more than ten years had passed, the Shuomie incident might have happened.

"It has been 12 hours and 37 minutes since you left. It is now 7:49 the next morning."

"Ah?" Leon raised an eyebrow. "I've only been walking for twelve hours, and you used the word 'finally'? Jarvis, I think you really need to reload your program logic for word choice and sentence construction."

"Master, these are the words I chose based on Mr. Stark's change in mental state after you left," Jarvis said.

"So Tony missed me very much?" Leon couldn't help laughing.

"I think so. Three hours ago, he would ask if you were back every seven minutes on average."

"What about the three hours just now? Was it once a minute?"

"Mr. Stark fell asleep three hours ago. Now he has been alerted and is rushing down."

"I seemed to hear you saying bad things about me just now?" Tony suddenly popped his head out from the stairs.

He was wrapped in a white scarf and it was obvious that he had just gotten out of bed and ran towards me.

"Look whose Peter Pan is. He finally decided to go home. Did he get wronged outside and come back to complain?"

As soon as Tony saw Leon, his excited expression instantly turned into laziness. He took a crooked step and fell on a chair.

"Isn't it because I'm worried that the empty-nest elderly people at home will be lonely?"

Leon felt a little funny: "I didn't expect that you can't leave me like this, Tony. It's only been twelve hours and you've already started calling my name in your dreams. Should I come back quickly?"

"I called your name in my dream, just kidding..." Tony laughed until he couldn't laugh anymore, "Jarvis said that?"

"What do you say?"

"Shet."

"Watch your language, Tony." Leon sat down at the table next to Tony.

"Sir, I did not tell Master Lyon that you shouted about his sleep talking 17 times in the past three hours." Jarvis complained.

Tony slapped him in the face, "Good, you said it now."

"Sorry, sir."

Tony turned his neck helplessly and looked at Leon again: "So, you suffered in the other world?"

"Why do you say that?" Leon was puzzled. Jarvis had just said the same thing.

Tony spread his hands and looked around deliberately: "It is very obvious that your Super Mark 1 is lost, along with the JARVIS subsystem inside."

His guess makes sense.

After all, Leon was still wearing armor when he left, but was alone when he came back. Something must have happened.

"So that's what you're talking about." Leon suddenly realized, "I left the armor there on purpose."

"The situation in that world is like this..."

He simply recounted the process of his time travel and what happened in the Resident Evil world.

It just omitted the part about studying the fusion of Kryptonian blood and virus.

Tony stroked his chin in thought: "World consciousness, and viruses...very interesting."

"But one thing is strange. You also spent twelve hours in that world?"

"That's right. You mean the speed of time on both sides is the same?" Leon nodded. "I thought of that, too. It's amazing, isn't it?"

Tony clapped his hands: "That's the problem!"

He picked up a box and a pencil and threaded the pencil into the box.

"You must know that the speed of time flows differently in spaces with different gravitational forces... Come on, don't tell me you don't know!"

Tony was serious as if he was in class.

Leon nodded in confusion: "Of course I know this, it's the theory of relativity."

According to the theory of general relativity, the greater the gravity in a region of the universe, the slower the flow of time.

"Excellent!" Tony pushed the pencil through the box.

He pointed to the pencils on both sides of the box and said, "Suppose this box separates two universes, and this pencil traveled through time."

“The left side of the box has more space, while the right side has less space.”

At this moment, the two of them were in the front half of the garage, and the size of the space was very aptly described.

"So!" Tony said, "Assuming that the larger part of the space has a larger mass, and the smaller part has a smaller mass, do you think the speed of time will be the same on both sides?"

Leon was stunned: "No... unless the masses of the two universes are equal, and the mass of the space in the part of the earth where I am is also equal."

"That's right." Tony put the box down and snapped his fingers. "But the chances of this happening are incredibly small. Do you still think it's reasonable for the two worlds to have the same time flow rate?"

It was as if a flash of lightning flashed through Leon's mind.

He frowned, suddenly realizing.

He would think that the speed of time flowing in the two worlds should be the same.

Actually, this is because it is written this way in many novels I have read before.

So he subconsciously thought so.

However, in fact, it is probably precisely this kind of thinking that leads to the same speed of time flow.

Tony looked at Leon's expression of realization before continuing, "I think that when you travel between two worlds, you are probably traveling through time."

"It's not like our world stops functioning after you leave."

“The vast universe will not stop and wait for you just because of your little energy.”

"The truth of the matter should be that you came back and entered this moment in time."

"As for when to start, whether it's the moment you leave or some time after you leave, it should be decided by you."

"And if you choose a different time entry point, your own consumption may also be different."

"You need to experiment a few more times on your own."

Tony once again felt the joy of educating his younger brother and patted Leon's shoulder proudly.

"You have to think more. Having a good brain is not enough. You have to think more, kid." Tony looked like an experienced person.

If he were in a different cultural background, he would probably say that he has tasted more salt than Lyon has walked.

Leon looked at Tony helplessly.

"You're awesome this time, okay?" He sighed.

So Tony became even happier and started humming a tune.

"Okay, take your time to be proud of yourself. I'll go back in time and try again." Leon chose to let Tony be beautiful alone.

"Wait!" Tony stood up suddenly, his white scarf falling off. "You have to take me with you this time. It's only 1% of the energy, one more person doesn't matter!"

"It's very dangerous. Don't get infected with the virus as soon as you go over there..." Leon glanced around and found a triangular light on Tony's chest.

"Hmm? You installed the reactor again. Does that mean you have successfully synthesized the new element?"

Tony smirked, "Yes, I synthesized it two hours after you left."

"I call it Badassium, what do you think?"

The corner of Leon’s mouth twitched: “How should I put it, it’s pretty awesome.”

"If Dad knew you named the new element like that, he would definitely get up and punch you."

"Sorry, the old guy has been cremated and can't get up." Tony has a talent for telling jokes from hell.

"So, will you let me go with you?"

"Hmm... I need to think about it. By the way, who said I don't like to think?"

"Who is it? Who dares to say that to you? Why is this person so annoying?" Tony pretended to look around.
