Washington.

Rosen took Tony and Happy and teleported directly to his garage.

Diana bought this house when she worked at the Smithsonian Institution for the convenience of going to work, and she lived here for many years.

However, since Diana became pregnant, she quit her job at the museum and moved to New York. The house here has been vacant, and the family only stays there for a few days when they visit Washington occasionally.

Although there are not many people living there, the house is always cleaned by hired personnel, so it is quite clean. The vehicles in the garage are also regularly maintained, so even if they are recent models, they are definitely in good condition.

"If you need anything, you can use the cars here." Rosen said, turning around and leaving.

"Hey, aren't you going to the hearing with me?" Tony stopped him.

"Why should I go? It's enough to have Pepper accompany you." Rosen waved his hand and said, "Besides, this kind of thing is nothing to you. I believe you can handle it easily.

"That's true." Tony nodded, with a look of "you know me" on his face, and then said: "I have something very important to talk to you about..."

"Let's talk about it after you solve the problem." Rosen said, snapped his fingers and disappeared.

"Wow!" Happy exclaimed, "Is he always this cool?"

"That's about right." Tony nodded.

"That's great." Happy said, "I suddenly feel like your private jet isn't that cool after all."

"I feel the same way." Tony pointed to the car keys hanging on the wall and said, "Stop talking nonsense now and pick a car. We have to leave quickly. If we keep Pepper waiting for too long, you know the consequences."

When Happy heard this, he quickly went to drive.

Rowe and Prince Estate, New York.

"I thought you would be gone for a long time." Diana was sitting on a sofa in the yard, reading a book. When she saw Rosen, she raised her eyebrows at him. There was a hint of provocation in her dignified manner, which immediately made Rosen's heart flutter.

"Is this an invitation?" Rosen smiled and sat next to her.

"No." Diana pretended not to understand what he said and said, "Don't change the subject."

"How long will it take to send them there and back?" Rosen hugged her and said, "Since we have nothing to do now, why don't we go inside and chat for a while?"

"Why do we have to go inside?" Before Diana could finish her words, Rosen picked her up and said hurriedly, "Listen to me, I have good news to tell you."

"Don't worry, we can talk about it slowly later." Rosen said with a smile: "I have accumulated a lot of good news to give you..."

There is no need to describe the process of the two people chatting back and forth. Anyway, it was almost noon by the time Rosen delivered the good news.

Rosen took a shower and went to the kitchen to cook.

It was not until about one o'clock in the afternoon during lunch that Rosen heard Diana lazily talk about her good news.

"The bandage made of a brand new material that you asked the group's medical equipment technology department to develop last time has produced some results." Diana said as she stood up, went to the next room to get a box and threw it to Rosen.

After Rosen opened it, he found two types of bandages that were completely different at first glance neatly stacked inside.

"These two bandages have not yet been officially launched on the market, so they don't have product names. They are internally referred to as Bandage No. 1 and Bandage No. 2."

Diana pointed to the snow-white bandage on the left and said, "Bandage No. 1 is made of high-molecular nano-tech materials. It has basic properties such as water absorption and breathability. What's more important is that the active ingredients on it can lock the wound faster, accelerate bleeding and wound healing."

Rosen took it, tore out a piece, held both ends with both hands and applied a little force.

Boom.

The bandage broke in two.

Rosen looked at Diana and shook his head. "Its tensile strength is too poor. It looks like it can only be used as a bandage."

"Then what do you want to do?" Diana was looked at by him and suddenly remembered the ridiculous game they had played some time ago, and her pretty face immediately blushed.

"Hehe, you know." Rosen grinned twice and picked up bandage number two.

"In the past six months, Spider-Man has been fighting violence on the streets almost every day. The spider silk he left behind has become research material for many scientific research institutions. It just so happens that the researchers in our group are also quite curious about it and have quickly obtained some research results."

Diana said, "Bandage No. 2 is made of optimized and improved spider silk. It is lighter, tougher, more resistant to pulling, and can withstand strong acids, strong alkalis, and fire."

"So many advantages?" Rosen pulled out a piece of No. 2 bandage, grabbed both ends and pulled hard.

Although the bandage was stretched to twice its original length in an instant, it still did not break.

Rosen pushed again, and when he had used nearly half of his strength, the spider silk woven into the bandage finally broke one by one.

This already made him quite surprised and satisfied. He looked at Diana and asked, "What are the shortcomings?"

"First, the cost is a bit high." Diana said: "According to your requirements, making a roll of bandage that is 20 meters long and 20 centimeters wide will cost at least 100,000 US dollars."

"Not bad, not bad." Rosen smiled and said, "I thought you were going to say it would cost 100 million."

"How can it be so expensive?" Diana said, "Another disadvantage is that it is afraid of sunlight. Under normal circumstances, it will gradually age and degrade after being exposed to the sun for about half an hour."

"Doesn't this mean it's even worse than ordinary spider silk?" Rosen said.

"Yeah." Diana said, "So you must pay attention to sun protection when using it during the day."

"Let them continue to improve the synthesis formula and try to overcome this shortcoming as soon as possible." Rosen picked up a roll of No. 2 bandage and said, "How many are there at home now?"

"Each roll is twenty meters long. There are about twenty rolls."

"It's enough for now." Rosen tossed the volume in his hand and said, "Diana, would you like to help me test its performance?"

"Bah, that's a nice thought."

Rosen smiled and said nothing.

Not long after the couple finished their meal, Tony came over.

"I have something very important to discuss with you." Tony looked at Rosen and Diana and said.

"About Stark Industries?" Diana asked.

"Ah."

"You two can just discuss it." Diana picked up the book she was reading halfway and walked away very casually.

"What do you want to do now?" Rosen asked.

"I intend to appoint Pepper as Chairman and CEO of Stark Industries," Tony said.

"What do you mean?" Rosen glanced at him and said, "You feel that you are about to die, so you are preparing to make arrangements for your funeral in advance?"
