"Damn, it crashed again! This is the second time this week, Professor," Martin complained with frustration. Martin Lewis, hailing from Africa, had been influenced by Chinese construction teams since childhood. She had heard about the generous scholarships available for studying in China, so after graduating from high school, she applied for a scholarship program at Tsinghua University in China. Thanks to her fluent Chinese, she smoothly passed the interview and is currently a second-year graduate student at the School of Materials Science and Engineering at Tsinghua University. It has been six years since she came to China.

The professor was also frustrated with Martin's complaint, as this had never happened before. The issue began when Martin introduced a high-entropy composite material model into the CST software on her computer. The computer would crash during performance simulation. A month ago, in the lab, while sintering a high-entropy metal and ceramic at 2000 degrees, an unexpected composite was produced. Martin named it E29 because it contained 29 different metallic and non-metallic elements. She didn't report this experiment to the professor as the material was still undergoing performance testing. Instead, Martin handed the material from the experiment to her friend Caesar, who worked in the hospital, hoping he could help her test the material's biocompatibility.

Due to the computer malfunction, Martin reluctantly headed back to her dormitory to rest. Walking on the campus, the sunlight fell on her dark skin. The sunlight here was far less intense than back in her hometown, but she knew she had made the right choice coming here. Suddenly, her phone rang—it was Caesar calling. She answered the call, but before she could speak, Caesar's urgent voice came through, "Hurry and come to my lab, quickly!"
