Leo handed all the small gifts he brought back to Aunt Jenny and Uncle George.

On the same day, I also came to Peter's house and gave him a lot of toys, as well as his own Iron Man model, which made seven-year-old Peter Parker really not like it.

In the evening, Aunt Jenny had been teaching Leo, she had promised to come back once a month, but she didn't come back more than a month, so she was angry.

Uncle George was also happy to see this scene, sitting on the sofa watching the ball game, holding a piece of pizza in his hand, and Jenny beating Leo on the side, Leo was always laughing, and the atmosphere was very lively.

The next day, Stark Industries' express delivery came to the door, and several tons of metal no less than gold and titanium alloys were put into the garage workshop.

At the same time, Harpy, who was following, also brought a small box to Leo's hand.

"Leo, what Tony asked me to give you personally seems to be very important. Would you like to open it and take a look?"

The chubby Hapi looked at the suitcase he took all the way, and he was also curious.

In the garage, Leo pressed the switches on both ends of the box, and the surface of the box flicked slightly, and a square metal block appeared in it.

Harpy became puzzled, "Does Tony tell me to bring you a piece of metal?"

Leo, with his faintly shining eyes, saw the reactor in it through the three-centimeter-thick metal wall. The strange thing was that the reactor was not connected to the metal, and the distance between the reactor was about one millimeter.

And this sealed metal block, the way to open it, seems to have no other way other than breaking it open violently.

Hapi stood aside and looked at Leo, covering his palms, and with a light touch, the metal block actually rose straight up, like a lid that was pressed together.

picked it up gently, and light shone from it, and a bright reactor lay quietly inside.

Harpy looked at the little thing in shock. This was the energy core of the steel armor, which he brought to Leo, and he didn't understand it.

Waiting for Harpy to leave, he sat in the car and called Tony, "Tony, did you let me bring an energy core to Leo? Did you install it wrong?"

"Oh, did he open it in front of you?"

Tony who was flying in the air asked, "How did he open it?"

"Didn't you set up a touch switch on the top, as soon as he presses it, the lid rises."

"Hapi, you come back first, that's what I gave to Leo."

hung up the phone, and Tony, who was covered with scratches on Mark 3, returned to his home, "Touch the switch? The lid? Seeing that Leo's control is getting stronger and stronger.

Jarvis helped to disassemble the Mark 3 and take it for maintenance. Tony also sat in front of the computer and couldn't wait to design it. The label at the bottom right corner of the drawing reads, "Mark 4"

Leo looked at the metal lid in his hand, "I couldn't do such a delicate operation before. It seems that the microscopic operation has given me a lot of control."

Looking at the small Ark Reactor, Leo also laughed.

If I absorb the home power supply, the whole street will be out of power, and the wires cannot withstand such a huge current impact.

Therefore, the Palladium Arc Mark II reactor will be Leo's best energy source at present.

With plenty of high-quality metals, Leo's cultivation speed will not drop much.

In the following days, Tony Stark often appeared on the front page news or cover of newspapers or magazines.

The red and gold steel figure is often seen in the sky over the United States

Mark 3 went to a certain battlefield and destroyed all weapons and equipment on the battlefield.

For a while, the wars in some small countries really calmed down a lot. After all, they couldn't be beaten, they couldn't catch up, and they couldn't break their defenses.

Tony just came over to destroy the equipment and then flew away. The weapon was scrapped before it was fired. These are all money.

Iron Man often appeared in news reports. He attracted the attention of the whole world, so there was a wave of Iron Man in the United States.

The handsome red-gold steel jersey was featured in Time Magazine's Man of the Year.

A large number of Iron Man's surroundings have emerged on the market, and the iconic mask has been sold out several times.

Leo stood outside the classroom watching the naive classmates in the playground wearing red and gold masks, running around there, still giving himself the sound of flying with a '' in his mouth.

During this time, Tony Stark can be seen everywhere, television, newspapers, magazines, news reports, he has become a great hero of the United States.

Countless people sing hymns to Iron Man every day, giving Tony Stark a higher position of support.

Soon many small countries began to imitate steel armor.

And a certain issue of Time magazine also specifically highlighted the reactor on the chest of Mark III.

Many people with ulterior motives have adjusted their focus to Tony's energy core and want to reach out and grab it.

But let alone the Ark reactor, even a large-scale arc reactor can't be built.

The technology of the Ark Reactor was completely in Stark's hands, and nothing was leaked.

No one thought that there would be an Ark reactor in Leo's hands.

In the first month, UU reading www.uukanshu.com, Tony would also make two phone calls with Leo, and send another reactor over, along with a few tons of metal.

In the second month, Leo also went to find Tony once, but he missed it with Tony who was out to save the world.

In the third month, Leo came to Stark's home again, and smoothly entered the underground studio.

Mark 4 has been formed.

Leo looked at Tony in one minute, using his robotic arm to wear it.

"Leo, I changed the appearance on the basis of Mark III, reduced the weight, and increased the flying speed a lot."

"Increase the internal space and cancel most of the Mark III connection mechanism to prevent lockup after armor."

"I added a system for filtering and reusing body fluids, and the appearance has become more handsome, right?"

Tony chattered a bit in front of Leo introducing the improvements to the Mark IV.

The mental state seems to be a little excited.

"Mr. Stark, has the reactor on your chest been improved?"

Leo immediately asked the key point.

"Of course, this is the new palladium arc Mark III reactor, which can directly replace the palladium metal plate, and I also made a spare, it will never happen again."

Tony waved his hand, a projection appeared directly in front of the two of them, and a brand new reactor emerged.

"But it hasn't been built yet. It should be done in a few days."

Tony clapped his hands lightly, and countless virtual three-dimensional projections appeared throughout the underground studio.

"Jarvis upgraded again. I upgraded and improved all the systems in the entire studio. Now the entire studio can perform projection."
