After a friendly exchange and reaching a preliminary agreement, Chen Yu and Tony left the Serenitea Pot.

Emerging from the Serenitea Pot, they startled Ethan and Pepper, who were carefully examining a floating teapot.

After a brief discussion, Ethan and Pepper also became very interested in Chen Yu's Serenitea Pot.

Chen Yu could only invite them both in as guests again.

When they came out again, Pepper and Ethan expressed that they also wanted a briefcase enchanted with the Undetectable Extension Charm.

Thus, Chen Yu gained two more customers.

The four returned to Tony's mansion and then got busy with their own affairs.

Pepper had to continue cleaning up the mess Tony had made.

Ethan had to go back to Stark Industries for work.

Tony wanted to continue inventing new Iron Suits and also wanted to get back the original MK1 Iron Suit from inside the Serenitea Pot.

He said that the conditions for making the MK1 Suit at the time were too crude, making it unsuitable as a gift, and that he would upgrade the first-generation suit and give it to Chen Yu after he had made the second-generation suit.

Chen Yu said it didn't matter, as he wasn't going to use it for combat anyway, and felt that the original suit had more collection value, so he firmly kept the original MK1 Suit.

Tony was helpless but also gave up on getting back the original suit.

After all, having invented a better second-generation suit, he really didn't care for the original anymore and let Chen Yu do whatever he wanted with it.

And Chen Yu felt that keeping it in his hands was better than leaving it with Tony, where he might accidentally fund his uncle, Obadiah.

He knew Obadiah was the villain in the first movie, but it wasn't appropriate to tell Tony directly, as Obadiah was Tony's uncle.

After Howard Stark's accidental death, Obadiah, as Howard's business partner and friend, became Tony's elder and had always openly given Tony various forms of support.

If he were to tell Tony now that Obadiah was ambitious and had long planned to replace him, and that the terrorists in Afghanistan were contacted by him to kill Tony and inherit Stark Industries' assets.

Would Tony be willing to listen to a magical young boy who saved him?

Or would he be willing to trust an uncle who had accompanied him since childhood?

Given Tony's current wild behavior and arrogant personality, he would be crazy to believe it.

So Chen Yu never mentioned this to him.

Chen Yu sighed, asked Pepper to help contact an oriental garden designer and building material supplier, and then drew a portal to go find Wang to learn magic.

Tony had given Chen Yu access to his laboratory, and Chen Yu saw the blueprints for the new suit he designed.

After seeing them, he was completely bewildered, feeling that he had overestimated himself; with his current knowledge as an undergraduate liberal arts student, he couldn't understand any of it.

He could only remember the general shape of the suit, but what good was that?

Instead of reading a 'heavenly book' at Tony's place, it was better to go back to Kamar-Taj and learn some more magic.

Especially the Mirror Dimension and Images of Ikonn, Chen Yu was envious of their effects.

The former can pull people into a Mirror Dimension space, which is a divine skill for opening up a battlefield; even if the entire Mirror Dimension is destroyed, it still cannot affect the real world.

It can be said that with this skill, there is no need to worry about affecting others during a battle.

Moreover, in the Mirror Dimension space, the caster can arbitrarily twist the surrounding terrain and environment according to their will, giving them a geographical advantage.

The latter, Images of Ikonn, also known as the Illusions of Ikonn, can create countless clones when cast, making it difficult to distinguish between real and fake.

Of course, it can also be used in an incomplete casting state, which is to grow many arms on the back, used to cosplay the Thousand-Armed Guanyin.

For Chen Yu, he currently doesn't need to split into many clones like Doctor Strange.

He only needs to try splitting one out to see if the clone can automatically learn knowledge.

If the clones split by Images of Ikonn can learn and cultivate independently.

Then he can go AFK in the future.

If study time is not enough, he can split into dozens of clones to study day and night, grinding system proficiency.

The Marvel Universe is too deep; he can split a clone and send him to the Marvel Universe to stir up trouble for him.

Anyway, they are all clones, so he's not afraid of them dying.

It can also save on healing items like Senzu Beans, which is simply wonderful.

The only pity is that both the Mirror Dimension and Images of Ikonn are relatively profound magic in Kamar-Taj.

As for Chen Yu's current knowledge reserve of Kamar-Taj magic, it can't be said to be none, but only a slight dabbling.

He is still in the stage of desperately devouring books.

When he has read most of the books in the Kamar-Taj Library, he will be able to learn these two profound spells.

It's a long and arduous journey.

During the last week of his vacation, Chen Yu's life was basically a three-point line.

In the morning, he went to the Library at Kamar-Taj to devour books.

In the afternoon, he went to Tony's laboratory to observe the progress of Tony's design for the MK2 Iron Man Armor.

In the evening, he went to the warehouse address Pepper had given him for construction raw materials and put all the raw materials into the Serenitea Pot.

As for the construction blueprints, Tony had jarvis search the internet for garden designs, then combined them and generated construction blueprints based on structural analysis.

Copying? What copying? It's an AI's work, how can it be called copying?

Anyway, Chen Yu also felt that no designer would visit his Serenitea Pot and then jump out to point at his nose and accuse him of plagiarism.

So, with no psychological burden, he took the design blueprints given by jarvis and started playing a giant Lego game in his Serenitea Pot.

As the vacation was nearing its end, before leaving, Chen Yu found Tony again.

He asked him to help build a children's pistol.

And he gave Tony a bullet, asking him to make a firearm according to the specifications that could fire this bullet.

The shape should preferably be a miniature version of a Desert Eagle.

Tony was puzzled by Chen Yu's request.

But he still had jarvis control the computer to use the forging machine to create two children's Desert Eagles.

The reason Chen Yu asked Tony to help build the pistol was that he had recently received a box of ten bullets with subtle attributes when completing daily tasks by helping an old lady cross the road.

【Item Name: origin bullet x10】

【Description: origin bullet is a Magical Artifact from the Type-Moon World. It is made from the powdered ribs of a certain human, condensed using soul engineering, and sealed as the core into ten of sixty-six bullets. It possesses the soul attributes of 'severing' and 'binding,' but unlike repair, the target object, once severed and bound, undergoes irreversible 'deterioration.' If used against a Magus, the origin bullet will sever their Magic Circuits and then crudely reconnect them, causing all of their Magic Circuits to short-circuit and run wild.】

Well, a special bullet for Magi, capable of making the opponent's Magic Circuits run wild and irreversibly damaged.

This is also the source of Kiritsugu Emiya being called the "Magus Killer."

He just didn't know how it would fare against wizards.

Chen Yu thought of Professor Quirrell, who was still lurking in Hogwarts.

He prepared to give two guns to Harry for self-defense and, incidentally, to verify the effect of the origin bullet on wizards.

Wonderful, killing two birds with one stone.

Putting the children's Desert Eagles made by Tony into his backpack, Chen Yu then asked Tony with some interest, "Do you have a small projector that can directly project videos in the air? I want jarvis to help create and synthesize a video, and then project it into the air, preferably with sound."

Tony looked at the inexplicably excited Chen Yu and asked with some confusion, "Why are you asking about these things?"

"Oh, it's like this, there's a bad guy hidden in our school, and I'm going to give him a little psychological shock."

Tony rummaged through a corner of the laboratory and threw Chen Yu a sci-fi-looking, palm-sized triangular holographic projector, explaining how to use it.

Then he had jarvis help Chen Yu make the video, while he continued to work on modifying his new armor.

Anyway, he had already helped make the guns, so this little bit of extra work didn't matter.

With jarvis, creating a lifelike video was a very easy task.

Following Chen Yu's description, it only took half an hour to perfectly replicate all the tasks Chen Yu had mentioned.

After getting what he wanted, Chen Yu bid farewell to Tony, saying he had to go back.

After Chen Yu disappeared from his sight, after a while, and confirming that Chen Yu had not returned.

Tony had jarvis restore the files that Chen Yu had synthesized, edited, and then deleted.

He opened the video that Chen Yu had named "Azkaban Admissions."

As a result, a wail from Tony soon echoed in the laboratory.

Perhaps this kind of performance art was still too avant-garde for people of this era.

"Fuck you! Chen Yu, give me back a pair of eyes that haven't seen this video!"
