“There’s a slight design flaw in the joints of this mechanical arm.”

Ethan, who was capable of designing the first generation Iron Suit with Tony, immediately spotted the defect when he saw Chen Yu fiddling with the abandoned Iron Suit arm on the ground.

Chen Yu listened to Dr. Ethan but couldn't find any flaws even after carefully examining it for a long time.

An amateur sees the excitement, a professional sees the details.

Chen Yu thought the Iron Suit arm was perfect and would definitely be an eye-catcher at home.

However, in the eyes of a professional, the problem was immediately apparent.

Ethan squatted down, pointed to the palm and surrounding joints, and explained to Chen Yu: “From a design perspective, Tony probably intended to install flight stabilizers and an impact laser cannon on the new Iron Suit arm, but he clearly overlooked the recoil issue. Also, these structural designs on the arm aren’t good. If the impact force is too great, it could easily cause the pilot's arm to fracture. I suggest he modifies it like this…”

Chen Yu could understand the first part of what Ethan said, but when he started offering suggestions for the Iron Suit arm, Chen Yu became a bit confused.

It was like listening to someone say: “I personally believe this spaghetti should be mixed with #42 concrete. Because the length of this screw will easily affect the excavator's torque. When you drive it in, it will instantly produce a large amount of high-energy protein…”

Every word was understandable, but when put together, it felt completely nonsensical, and he couldn't grasp the underlying logic.

His brain simply wasn't enough.

Is this the world of science and engineering giants?

Seeing Chen Yu's bewildered expression, Dr. Ethan patted his own head and said apologetically: “Sorry, it’s a work habit. I used to explain problems to graduate students, and now it’s become a conditioned reflex.”

Perhaps Ethan's eloquent discussion affected Tony,

but Tony didn't show any displeasure. Instead, he waved his hand, had jarvis save and close the almost-finished blueprints, and turned to Ethan, saying: “Ethan, this armor arm was just made casually based on a sketch to see the effect. It's not a formal piece of work at all, and besides, all those problems you mentioned have already been solved.”

“Solved? Then there's no problem. What material are you planning to use for the new Iron Suit?”

“I’m planning to use titanium alloy fiberglass to make the second-generation Iron Suit. It's very light and very strong.”

“What about the internal shock absorption system?”

“It's still being perfected, but I already have an idea. I'm going to invent a highly elastic viscous polymer…”

Then he threw out another string of technical terms, leaving Chen Yu in a state of bewilderment once again.

Watching the two start discussing the armor animatedly, Pepper shrugged: “Tony is always like this. He gets completely lost in thought when he talks about his inventions. Chen Yu, what would you like to drink? Milk? Juice? Or coffee? We also have tea bought from the East, would you like to try some?”

“Just a glass of plain water, please. Thank you.”

Although Chen Yu didn't understand what the two of them were saying, he tried hard to remember it.

These were insights into mecha design from great minds. He quickly jotted them down, thinking they might be useful when he completed his task of designing a magical mecha.

Chen Yu only listened for half an hour before returning to the living room with Pepper.

He couldn't understand it, not at all. Without a foundation, this stuff was more taxing to listen to than magic.

Pepper truly treated Chen Yu like a child. She opened a laptop and had Chen Yu watch “Tom and Jerry” cartoons to pass the time, while she continued to handle company affairs on another laptop.

Chen Yu wasn't actually a child, so how could he be attracted to “Tom and Jerry,” which he had watched n+1 times in his childhood?

Seeing the familiar scene of Tom chasing Jerry, and realizing that Tony and Ethan's conversation showed no signs of stopping, he decided to glance at it to pass the time.

Soon, Chen Yu was engrossed in the screen,

He watched five episodes of the cartoon continuously until he felt someone tap his shoulder, and then he suddenly snapped out of it.

Who stole my time?

This cartoon was truly terrifying. Even though he already knew the plot, he still watched it with relish like a child.

“Long time no see, Little Wizards! So glad to see you!”

Tony had now changed into a refined suit, looking as if he was about to attend a banquet.

Chen Yu was now certain that the nickname Tony gave him was intentional.

His naming talent was terrible, as smelly as his father's socks.

Looking at the culprit who gave him such a terrible nickname, Chen Yu wasn't so polite.

He really didn't want his nickname “Little Wizards” to spread throughout New York and even the world in the future: “Tony, call me Chen Yu, or address me as Wizard Chen Yu. This is the final warning; I don't want this terrible nickname to get out!”

Tony looked indifferent: “Terrible? I clearly think this nickname is cool! I'm even eager to hold a press conference to announce it!”

“Then if you do that, I'll just have to silence you permanently.”

Tony sat on the sofa, with his arm resting on the back, looking indifferent: “Really? Are you going to kill me with your little wand, shooting out green zapping lights? Oh my, that's too terrifying! Don't you agree, hahaha…”

Pepper and Ethan couldn't help but burst into laughter at Tony's exaggerated performance.

Indeed, Tony was still Tony. Even if he had changed somewhat, he was still a playboy with a loose tongue.

Chen Yu decided to give Tony a small punishment to teach him some respect.

He pulled out his wand from his backpack and cast a Tongue-Tying Curse directly at Tony.

Tony, who was laughing loudly, suddenly felt something was wrong with his mouth.

His tongue suddenly stuck to his palate; they were tightly glued together, and no matter how much force he used, he couldn't pull his tongue down.

Tony suddenly made “hmm hmm hmm” sounds, then tried to pull his tongue in his mouth with his hand.

Pepper was frightened by Tony's reaction and quickly went to check on him.

“Mr. Tony, your tongue is currently controlled by an unanalyzable force. External force cannot pull your tongue from your palate. According to analysis, unless the entire tongue is removed, surgery cannot resolve your current state. He who tied the bell must untie it. It is recommended that you apologize to young Mr. Chen Yu, Mr. Tony.”

Listening to the intelligent butler jarvis, Tony quickly raised both hands, indicating surrender.

Seeing Tony raise his hands in surrender, Chen Yu removed the spell controlling Tony's tongue.

Feeling his tongue return to normal, he rubbed his chin with his hand, then said to Chen Yu: “A magical experience. I suddenly felt like I couldn't control my tongue. Can you tell me how you did it?”

Chen Yu wiggled the wand in his hand: “Naturally, it's magic.”

“Magic?” Tony rubbed his face, “Although I was mentally prepared, I still didn't expect something from a children's story to actually exist.”

Tony accepted Chen Yu's explanation. After all, his worldview had already been shattered five days ago, and it was time for it to be rebuilt.

So, he curiously asked Chen Yu: “Can magic achieve other effects?”

Chen Yu nodded: “Invisibility, flight, teleportation, curses, object transfiguration, hypnotic control, and so on.”

“Sounds cool, and very dangerous.” Tony nodded seriously and said to jarvis: “jarvis, note down what Little Wizards Chen Yu said, and remember to remind me later.”

“Are you trying to trick me into talking?”

Chen Yu became a little alert.

This guy Tony isn't starting to conceive anti-XX series armor already, is he?

Then he slowly relaxed.

Never mind, his anti-XX series armor always gets beaten; he's never successfully countered anything.

Besides, all the spells he knows are from another world. If he wants to design anti-wizard series armor, he won't cooperate and won't provide a sample. The most he can design is anti-mage armor.

Anti-mage armor, what does that have to do with me, a wizard?

How about Mordenkainen's Disjunction?

It will turn all your various armors into dust.
