Summon the Villain: Marvel.

Tony Stark is wearing a well-cut black suit with delicate silver buttons on the jacket and a white shirt with a slightly open collar, which looks both formal and stylish. He wears a high-end mechanical watch on his wrist, the dial is simple and elegant, and the hands are shining coldly in the sun. He wears a small and exquisite single-ear headset on his ear, which looks simple but full of technology, so he can connect and communicate with Jarvis at any time.

Tony walked into the lobby on the first floor of the Umbrella headquarters, his eyes wandering around. His eyes were full of curiosity and scrutiny, carefully looking at the surrounding Xumagia. They have smooth shapes, elegant movements, and no unnecessary decoration, but every detail shows the texture of high technology.

Jarvis' voice came from Tony's headset, with a hint of mechanical calmness and gentleness, "Sir, are you interested in Xumagia's design?"

Tony chuckled, put his hands in his trouser pockets, and continued to observe the actions of these Humagias. "Jarvis, do you think I should give you a body like this so that you can move around instead of staying in my equipment all the time?"

Jarvis was silent for a moment, as if he was thinking seriously about the proposal, and then responded, "Sir, this is indeed an interesting idea. However, I think I can better serve you in my current state. Although the Humagia are flexible, their capabilities and data processing speed are far inferior to my current efficiency."

Tony nodded, the corners of his mouth slightly raised, "Jarvis, you are always so pragmatic. However, sometimes having a body that can experience the world in person may bring some unexpected pleasures."

Jarvis' voice was a little relaxed. "Sir, your consideration is very thoughtful. However, I prefer seamless management and monitoring in the virtual world. If you need it, I can always provide you with the most accurate information and analysis."

Tony smiled slightly, with a sly look in his eyes, "Okay, Jarvis, let's keep the status quo. But remember this proposal, maybe one day I'll want you to try it."

Jarvis responded with a hint of humor, "Understood, sir. If ever you decide to let me have a physical body, I'll be looking forward to that moment."

Tony Stark walked into the Umbrella Park, taking a confident and steady step, and went straight to Kreutz's laboratory. The park was shaded by green trees, lush flowers and plants, and various high-tech buildings were scattered in an orderly manner, full of a sense of the future. The sun shone through the gaps in the leaves and sprinkled on the ground. The air was filled with a faint fragrance of flowers, making people feel relaxed and happy.

Kreutz's laboratory is located in the center of the park. It is a silver-gray building that towers into the sky. Its exterior walls are as smooth as a mirror, reflecting everything around it. There is a huge glass door at the entrance of the building, which opens automatically to welcome Tony. Tony walks into the laboratory and sees a huge genetic modification and biological experiment area.

The laboratory was brightly lit, surrounded by various high-tech equipment, flashing a cold blue light. The white laboratory table was filled with sophisticated instruments and test tubes, and the researchers were wearing white lab coats, performing various experimental operations with concentration. The air was filled with the smell of disinfectant, with a hint of coldness and seriousness.

Tony's eyes swept through every corner of the laboratory and saw several researchers busy in front of a huge transparent incubator, which was cultivating various strange creatures, some of which even looked mysterious and had strange shapes. The monitoring screen next to the incubator displayed various data and charts, and the flashing lights made people feel as if they were in the future world.

"Tony!" Kreutz came out from a corner, wearing a white lab coat, with messy hair, but his eyes showed a hint of excitement and concentration. He walked quickly towards Tony, with a warm smile on his face, and stretched out his hand, "Welcome to my lab, old friend!"

Tony smiled, shook Kreutz's hand, and patted his shoulder gently, "Kreutz, long time no see. Your laboratory is really amazing. Every time I come here, I feel like I have entered another world."

Kreutz smiled, his eyes sparkling with pride, "Tony, you are always so polite. Over the years, we have made a lot of progress in genetic modification and biological experiments. Come, I will show you around."

Tony nodded and followed Kreutz through the lab. They walked past rows of fluorescent lab tables and busy research teams, while Kreutz introduced and explained in detail the progress and results of each project.

"This is our latest gene editing platform," Kreutz said, pointing to a complex machine with a series of ever-changing gene sequences displayed on the screen. "Through CRISPR-Cas9 technology, we can precisely cut and repair specific gene sites. This platform can not only repair genetic defects, but also enhance the disease resistance and adaptability of organisms."

Tony nodded and looked at the data on the screen carefully. "This technology is really amazing. How did you solve the off-target effect? ​​I remember that this has always been a big problem with CRISPR technology."

Kreutz smiled proudly, "We have developed a new Cas9 variant that can more accurately recognize the target sequence while greatly reducing the off-target rate. In addition, we have combined a machine learning algorithm to predict and avoid potential off-target sites, thereby improving the accuracy of editing."

Tony's eyes flashed with admiration. "This is indeed a major breakthrough. How did you obtain the training data for your algorithm?"

"We have collaborated with multiple gene databases around the world to collect a large amount of gene sequence data," Kreutz explained. "With this data, we are able to continuously optimize our algorithm and improve the accuracy of our predictions. In addition, we have conducted a series of experimental verifications to ensure that our technology is equally reliable in practical applications."

Tony nodded and continued to follow Kreutz. The two came to another experimental area, where there were several large incubators, in which various organisms were cultivated.

"These are our genetically modified organisms," Kreutz pointed to one of the incubators. "Through gene editing, we can give these organisms new abilities. For example, in this small rodent, we have enhanced its immune system so that it can resist a variety of infectious diseases. At the same time, it also has the ability to repair itself and can heal wounds quickly."

Tony looked closely at the creatures in the incubator, his eyes full of curiosity. "Are there any ethical issues in the genetic modification of these creatures? How do you deal with these issues?"

Kreutz's expression turned serious. "This is an issue we have always taken very seriously. All our experiments strictly follow ethical standards and have undergone multiple levels of review and approval. In addition, we have set up a special ethics committee to oversee our research and ensure that no unnecessary harm is caused to organisms."

Tony nodded to show his understanding, and his eyes moved to another incubator, which contained a strange plant with leaves flashing a faint fluorescence.

"What is this?" Tony asked curiously.

"These are fluorescent plants that we have bred through gene editing," Kreutz explained. "These plants are not only ornamental, but can also provide a weak light source at night. We hope that through this technology, we can reduce energy consumption and create a more environmentally friendly lighting solution."

Tony smiled appreciatively, "Your research is indeed very promising, not only in the medical field, but also in environmental protection."

Kreutz nodded and continued to lead Tony forward. They came to an independent laboratory with a huge device that looked like a high-tech bioreactor.

"This is our latest bioreactor," Kreutz said. "With it, we can produce genetically modified cells and tissues on a large scale. This will provide a more efficient and economical solution for medical research and treatment."

Tony looked at the device carefully, his eyes sparkling with interest. "What is the production efficiency of this device? Can it meet the needs of large-scale applications?"

"We have conducted many tests and the results are very satisfactory," Kreutz said confidently, "This bioreactor is not only highly productive but also has stable quality. We believe that it will play an important role in the medical field in the future."

Tony nodded excitedly and smiled with satisfaction. "Kreutz, your research is really exciting. I am very happy to see that these technologies have developed so rapidly in your laboratory."

Tony suddenly stopped, a trace of emotion flashing in his eyes. He looked at this high-tech and futuristic laboratory and said softly: "Kreutz, the resources and scientific research capabilities of your Umbrella Group are really amazing. You and Zhan Ji Lingma are both the best I have ever seen."

Kreutz smiled slightly, with a hint of humility and satisfaction in his eyes, "Tony, you're too kind. I only have such opportunities and resources because I am in Umbrella. These achievements are inseparable from the support of the Umbrella Group. If you join us, I believe you will be the one to manage the Iron Legion."

When Tony heard this, the corners of his mouth slightly raised, and his eyes flashed with a hint of pride and confidence. He gently patted Kreutz's shoulder, and said with a bit of teasing, "Kreutz, you are really good at complimenting people. But Iron Legion, if there is a chance, I would like to cooperate with you and see what miracles we can create."

Kreutz smiled sincerely and nodded. "Tony, no matter what, we are looking forward to working with you. Your talent and wisdom will surely bring us more breakthroughs and progress."
