Be a Good Elder Brother with the System (Qing Chuan)

Juan Gu read the story about Prince Qing's rebirth before going to bed, and when he woke up, he transformed into the big brother in the story. A bolt from the blue! Has he turned into the eldest brother Yin Yin who had to be the prince's whetstone because he was the longest in the line? The two have been in love and fighting each other for more than thirty years, both of them suffered losses and neither ended well? After the prince was reborn, he learned his lesson and began to deal with the disgraceful elder brother. In the end, he ended up with a cannon fodder brother who was even worse than his previous life? ! The future is gloomy. Fortunately, he awakened the system in time, and the mall sells everything, including butterfly pills, detoxification pills, vigorous pills, contraceptive incense, male and female birth pills... System: "Are you worried about your future situation? Are you heartbroken by Kowloon's seizure of the heir? This system is the best helper for the host to protect itself!" Juan Gu, who was hopeless, quickly said: "Okay, let Khan Ama give up the idea - no longer let me be the prince's whetstone. The ability to protect my life depends on you!" . The reborn prince Yinreng was also shocked. Everything in this life has actually changed beyond recognition: Most of the brothers are mysteriously missing? ! All the sons of Khan Amma were only these few: The eldest brother who is good at martial arts, he is the prince himself, the third brother who is Xiwen, the fourth brother who is practical, the fifth brother who is generous and fat, the sixth brother who died young, and the seventh brother who is crippled by nature. The too few heirs led Khan Amma to cherish every child. Kowloon seizes the direct descendant? No longer exists. A battle between the heirs? He no longer exists. There is nothing wrong with this big brother! Yinreng dares to swear that he is definitely not the reckless and impulsive elder brother in his previous life! Who is he? But... Looking at the kind-hearted and eldest brother in front of him, who was waiting for him to go to the study together, Yinreng felt that it didn't matter who he was. The important thing is, it's best not to change it back for the rest of your life! This big brother... Is pretty good. Note when reading the article: 1. Kowloon's inheritance was lost to Butterfly, but the remaining elder brothers will still be born reasonably. In the whole story, only the reborn prince has the memory of rebirth, and the male protagonist has the memory of time travel. The other elder brothers are no special. Intention: As long as you work hard, you can live towards death no matter how dangerous the situation is.
