After Star Han agreed to treat Onlooker's legs, they discussed and decided that Onlooker would temporarily move to Star Han's rented place for the convenience of treatment. In order to expedite her recovery, Onlooker immediately made a few phone calls and then urged Star Han to take her to his home, as if afraid that he would change his mind once he left.

Seeing her anxiousness, Star Han sighed and said, "You don't have to worry like this. I promised to help you, and I will do my best. Did your parents agree to let you stay at my place?" It would be troublesome if her parents didn't agree, but it would also save them some trouble.

"They don't care about me. My dad only knows how to make money, have affairs, and keep mistresses outside. He never comes home. One day he's at a club, the next day at a fashion show. He has no time to care about me. Even if I die, they won't know," Onlooker said with some resentment.

"There's no need to rush like this. I also need to tidy up my place and prepare a room for you to stay in," Star Han said.

"It's okay. As long as there's a place for me to stay, I don't mind. Take me there now," Onlooker said.

Due to Onlooker's physical condition, they took a taxi directly to Star Han's home. When they arrived at the front door, Onlooker couldn't walk, so Star Han had to carry her upstairs. Just as they reached the top of the stairs, they ran into Yu Ya, who had returned from school. Yu Ya saw Star Han coming back and said happily, "Brother, you're back! I've been waiting for you for so long." However, when she saw Star Han carrying a beautiful girl in his arms, her expression dimmed for a moment but quickly recovered. She asked, "Brother, who is this?"

Star Han hadn't paid attention to the situation. He felt a bit awkward. He brought a girl home without even telling Yu Ya. It was somewhat uncomfortable. He introduced them, saying, "This is my younger sister, Yu Ya. And this is my online friend, Onlooker." Then he immediately turned to Yu Ya and said, "Her legs are a bit problematic. She came here for treatment."

"Yu Ya, I hope you don't mind me calling you that. You're so beautiful," Onlooker admired.

"I don't mind. Thank you for the compliment. You're even more beautiful than me," Yu Ya quickly responded to Onlooker's praise.

Seeing that the two of them got along well, Star Han breathed a sigh of relief. He immediately said to Onlooker, "You must be tired from the journey. Let me take you to your resting room. Rest well, and I'll treat your legs tonight."

Star Han brought Onlooker to his former room and said, "You'll be staying in this room from now on."

Onlooker casually agreed and then said, "Star Han, no wonder you didn't take me seriously. It turns out you have such a beautiful sister accompanying you."

Hearing her words, Star Han quickly clarified, "Don't say that. She's my sister."

"Sister? She's definitely a good sister to you. But I'm afraid she's the kind of 'sister, you sit in the front of the boat' sister. You can't deny it. It seems like she has deep feelings for you," Onlooker teased.

"Is that so? Don't make baseless assumptions. We really don't have anything between us. You should rest well," Star Han said as he walked out, ignoring Onlooker's doubtful head-shaking. Did Yu Ya really think that way? Star Han couldn't help but wonder. To be honest, spending so much time with Yu Ya every day didn't leave him completely unaffected. After all, Yu Ya was now an adult. And sometimes, it seemed like Yu Ya was intentionally or unintentionally showing her charm in front of him. Star Han always reminded himself that she was his sister and that he shouldn't cross any boundaries. That's why they got along without any issues. But now that Onlooker brought up the matter again, Star Han realized that he might need to find a solution, or else trouble might arise in the future.

In the living room, he saw Yu Ya still sitting there and approached her, asking, "Sister, is there something you need?"

"Oh, nothing. Is Onlooker the person you met online, Brother? She's really beautiful. But what's wrong with her legs?" Yu Ya asked.

"It's a nerve problem. Her muscles have atrophied. If we don't treat it now, it may become untreatable. However, I'm not completely confident," Star Han said with some concern.

"Brother, do you like her? Otherwise, why would you help her with her legs?" Yu Ya suddenly asked.

"Well, it's hard to say. I didn't know about her leg problem initially. It was her request, and I couldn't refuse. I'm only helping her with the treatment. Once her legs are healed, we'll have nothing to do with each other," Star Han explained helplessly. Why do girls always ask such questions?

"Oh, I see," Yu Ya said, somewhat unbelieving, but she didn't ask further. It's good that she didn't ask. Star Han was also troubled by how to explain this situation.

That evening, Star Han unfolded the sofa and set up a makeshift bed for himself, preparing to sleep on it. Since the house only had two rooms, he didn't feel comfortable asking the ladies to sleep on the sofa. However, in the end, after discussing with Yu Ya, they decided that Onlooker would sleep in Yu Ya's room, and on weekends, when Yu Ya returned, the two of them would sleep together, allowing Star Han to continue sleeping in his own room. Star Han saw that they seemed to get along well, so he agreed.

In the following days, Star Han lived a very disciplined life. He went to school during the day, treated Onlooker's legs in the evening, and spent his free time trading stocks online, with Onlooker providing advice. He never asked for Onlooker's real name, and they both tacitly avoided discussing each other's personal matters. Yu Ya and Onlooker got along well and had conversations filled with laughter.

Treating Onlooker's legs went smoothly for Star Han. It wasn't as difficult as he had initially imagined. Perhaps he had underestimated his own abilities, or maybe Onlooker's condition wasn't as severe as he had thought. In any case, these things weren't important. What mattered was that they could treat Onlooker's condition without much trouble. However, it would probably take a few months or half a year for Onlooker's legs to fully recover.

In order to stay updated with stock trading, Star Han subscribed to several newspapers to keep himself informed about national affairs for reference when trading stocks. Stock market fluctuations were often closely related to current events, and China's stock market had a close connection to politics.

This time, he did pay attention to the newspapers, starting with international news to see if there was anything worth noting. One piece of news caught his attention. Country A and Country B were on the brink of war. Although it hadn't been officially declared, everyone knew it was only a matter of time. Of course, where there's war, there are also opportunities. As the war progressed, it would inevitably affect the stock market. If he seized the opportunity, he could make a substantial profit.

Star Han discussed his thoughts with Onlooker, and she agreed that it was a great opportunity. If they played their cards right, they could earn a significant amount. However, she said, "This is a big deal. I think we should consult someone more knowledgeable. I used to interact with many stock traders online, and there was one particularly skilled person. He was said to have been a prominent figure in the stock market. He later quit for unknown reasons. I met him quite by chance. He was kind to me and often said that I had the potential to be a great stock trader. If I had been interested, he might have taken me as his disciple."

"Oh, really?" Star Han was somewhat skeptical.

"Yes, even if he turns out to be a fraud, there's no harm in consulting him," Onlooker said.

"Well, give it a try then!" Star Han replied casually.

It didn't take long for Onlooker to contact the person. Judging from his voice, he sounded like an elderly person. After listening to Onlooker's words, he immediately agreed to help and even pointed out a few stocks worth buying. Star Han carefully considered the stocks he suggested and realized that if things developed normally, those stocks indeed had great potential for profit. He couldn't help but admire.

In the following days, Star Han closely followed the progress of the war. However, he didn't buy any stocks because the timing wasn't right. Buying now would be a waste of his energy without any real benefits. The real opportunity would come with a turning point in the war. It was a war with a known outcome; it was only a matter of how long it would last and the price paid.

Due to B country's guerrilla warfare tactics, the progress of the war was slow. By the second week of the war, there were doubts about A country's government's claims of a swift and decisive victory. Some even believed that the war would become a protracted conflict, and the final outcome would be a pyrrhic victory. As a result, the prices of many related stocks began to decline and reached their lowest point by the end of the third week.

One day, when Star Han returned after class, he practiced the Clear Mind Technique for a while. Suddenly, an idea came to mind. He quickly turned on the computer. Due to the war's impact, several stocks' prices had almost halved. Star Han told himself, "Now these stocks' prices are far below their value. Once the war ends, they will surely rise again."

Regarding the outcome of the war, there was no doubt among the public that it was only a matter of time. These stocks were unlikely to fall further. If he seized the opportunity, he could reap substantial rewards.

Star Han believed his judgment was correct and mobilized two million in capital, overdrawing fifty percent of it, to invest in these stocks. However, right after placing the order, he started to feel regret. He had risked all his capital this time, and if his judgment was wrong, he would truly be left with nothing. Star Han regretted not the act of placing the order but the fact that he had invested too heavily, leaving himself no room for retreat.

For the next few days, as soon as Star Han arrived home, he would check the computer to see if the stock prices had risen and if there were any turning points in the war. He appeared exhausted in class every day, and Onlooker had to comfort him.

Fortunately, his persistence paid off. It didn't take long before the war took a major turn. The previously deadlocked situation was broken, and the war became completely one-sided. Commentaries stated that the war would soon come to an end. Stock prices began to rise, and in no time, they doubled from the price at which Star Han had purchased them. At this point, Star Han sold all the stocks he held. He had heard a saying, "You can profit from both going long and going short; only the greedy ones miss out on profits." Although it wasn't a famous saying, Star Han remembered it. After selling everything, he calculated that he had invested two million and overdrafted one million, which amounted to three million. In this buying and selling process, he had almost tripled his capital. After deducting various fees, he still had over five hundred thousand. In other words, within just over ten days, Star Han had earned nearly three million. He had never made so much money before and was extremely delighted. Star Han thought to himself, no wonder so many people want to trade stocks. Sometimes, the money in the stock market comes too quickly. He left three million in the stock market as his capital and transferred the rest to his bank account.
