She was about to "commit suicide" as soon as she traveled through time. In desperation, the scientist girl used Arabic numerals to save her own life. She originally just formed an alliance with him for revenge and made money by making glass. Unexpectedly, with his help, she actually made the elusive generator and light bulb. They made a lot of money, and she wanted to retire with Li, but he regretted it: "I saved that child, you owe me three things." She said: "The world only knows that the divine fire is bright, but they don't know that it can kill people invisible. I will help you subvert the country and help you take revenge. You let me go!" So, they overturned the country together, and he regretted it again: "I gave up this country, let's wander around the world together, okay?"
