Captain America Steven joined S.H.I.E.L.D. after the Battle of New York and is now following Natasha around the world. Tony has been locked up in his studio since his return to Los Angeles to work on his new armor, while Hawkeye goes on vacation after the fight.

Kerr returned to his apartment in Queens after taking care of things, and when he came to the door of his apartment, he found Peter sitting in front of the door, reading a book. "Peter, why are you sitting in the doorway?" "Mr. Kerr, my aunt has gone out and hasn't come back, and if mine forgets to bring it, I'll have to sit outside." "I see, come to my house for a meeting, and you will come there when your aunt returns." "Is that okay?" "Of course."

At Kerr's invitation, Peter came to bring Kerr's room, Kerr poured Peter a glass of water, Peter sat on the sofa and looked at the book quietly, this is a book on physics, Kerr asked, "Can you read this book?" "Of course, it's just hard, and there are some things that I can understand."

"If there's anything you don't understand, you can tell me." Peter's expression was a little confused. "I'm a physicist, so I can understand general physics problems." "Mr. Naker, do you know what this place is all about?" After Kerr identified himself, Peter asked his own question, which Kerr answered carefully, and finally Peter became more and more impressed by Kerr's knowledge.

When Kerr heard the sound of the door opening, Kerr knew it was Peter's aunt who had returned. "Peter is supposed to be your aunt back." "Thank you, Mr. Kerr, I'll go back first." After saying that, Peter opened the door and went outside. Peter's aunt was puzzled when she saw Peter coming out of Kerr's house. "Well, Peter forgot to bring the key, so at last Peter sat at the door, and before I was there, I called him to my house to rest for a while." "Is that so? Thank you so much, Mr. Kerr. "No thanks."

In a week, Kerr is also going to Los Angeles, and I'm going to start modifying his armor, this time Kerr is going to add two energy gauges to his armor, and use the energy from his scepter and cosmic magic to use it on the armor, and the different energy characteristics will bring different effects to the armor.

As for why he went to Los Angeles, he mainly thought that it would be difficult to get the equipment to modify the Warframe in New York, so Kerr's best option was to go back to Los Angeles, where his old lab was located, and she was more familiar with it, so Kerr would be more efficient there.

Hill followed Kerr on a plane to Los Angeles, and after arriving in Los Angeles, of course Kerr had to visit Tony, and when Tony arrived at the villa, Kerr learned from Little Pepper that Tony had been in the studio for more than a month and hadn't come out, and she had been worried about Tony's state, but Tony had always been disgusted with Pepper discussing his physical condition. She hopes that Kerr's arrival will bring Tony some help.

With Pepper's hope, Kerr arrives at the lab and sees Kerr working on a suit of armor. "Hey Tony, what is the set of your armor updated?" "This should be Mark 25." Kerr looked at the armor with two huge heads on his arms, "Are you using this armor to decorate the house?" Kerr quipped, "Why, this is what I used to make a hole in your house." ”

"Okay, then wear this armor to my apartment and make a hole, I heard I haven't been out for more than a month. It's time to get out for a walk. Kerr said. Kerr looked at Tony's somewhat tired eyes, knowing that Tony hadn't had a good night's sleep in a long time.

"Okay, how about we go cheeseburger together?" Tony said. "Of course, you can go now." Kerr said, and then the two of them drove Tony's Rolls-Royce to a burger joint and ate cheeseburgers.

"How are you doing during this time?" Tony asked. "Of course, I've lived a fulfilling life. And there are no aliens, the Hydra is dangling in front of my eyes, and there is no fight and no explosion. Listening to Kerr's words, Tony suddenly thought back to the scene of the Battle of New York, and the scene of him holding a nuclear bomb and rushing to the portal. Suddenly, he put down the hamburger in his hand, and looked weak and began to lose his footing.

"What's wrong Tony, what's wrong with you?" Kerr quickly helped Tony, "I'll take you to the hospital." ”

Tony grabbed Kerr and sat back down in the chair, "I'm fine, I'm just a little tired." "In that case, I'll send you back to rest." You just don't drive. Kerr and Tony didn't eat any more burgers, and Kerr drove Tony back to Tony's home.

The days that followed were when Kerr modified his Warframe, but Kerr encountered difficulties, and after two months of experimentation, Kerr still couldn't find a suitable way to make the Warframe compatible with energy.

Reluctant to give up, Kerr experimented again for a month and still had no results, Tony has been updating his armor in the studio for these two months, and he will only come out of the studio when Kerr goes to visit him, Kerr has always felt that Tony should be something else, his state is very abnormal, but he can't say what's wrong.

In the past few days, several major events have taken place in the United States, and terrorist bombings have occurred in various important places in the United States, and the person who claimed responsibility for the explosion was a man named Mandarin, who claimed to be the leader of a terrorist in the Middle East, and what he did was a lesson to the President of the United States. And no, it's still on TV to spread his videos.

One day, Tony came to a restaurant for dinner at the invitation of Colonel Roddy, and at the same time, Tony also called Kerr, who was upset by the modification of the armor, so he accepted the invitation. Kerr watched the news on TV that the war machine was painted in the color of Captain America and that the president would send him to arrest Mandarin, and Kerr couldn't help but complain, "If you change to Captain America's color, you will be called Iron Patriot?" "The name War Machine is so bloody, it would be better to replace it with War Machine." "What's going on with that Mandarin, can you tell me a little bit seriously?" Tony has been attacked by terrorists, so Tony is very concerned about things about terrorists, and this Mandarin has so many terrorist attacks on the United States that it has seriously caused panic among people. "Tony, it's classified, all I can tell you is that there were nine explosions, and people only know about three more. The most important thing is that no one has found the detonating device, there is no shrapnel at the scene, and now the pentagon is in a panic, and we can't even find any information about Mandalin, so he thinks it appeared out of thin air. Colonel Roddy whispered to Tony and Kerr.

Kerr heard a lot of problems from Colonel Roddy's words, such as not being able to find Mandarin's information, and not finding Mandarin's traces, this kind of thing rarely happens, as long as Mandarin exists in this world, Kerr believes that this person will show his feet. Colonel Roddy continued: "Since the Great New York War, even aliens are not worth mentioning, but this matter concerns the whole of America, so the danger caused by terrorists is more feared than any aliens. ”

Colonel Roddy's words reminded Tony of the Great Battle in New York, he became weak and anxious again, Kerr noticed his state, and Kerr asked with concern: "Tony, are you okay?" ”

Tony staggered out of his chair and went outside to put on his armor, "Jarvis, check my body." "Sir, everything is fine with your body, and my diagnosis is that you have a severe anxiety disorder." "How so?" That's when Kerr and Colonel Roddy walked out and looked at Tony. "Guys, I think I'm going to go first." With that, Tony flew away. "Tony, what the hell is going on?" "I don't know, judging from his condition, he must be suffering from severe anxiety. There's nothing we can do to help him. Kerr said.
