[Urban high martial arts + family feud + sister crematorium + single female protagonist + multiple female supporting characters + invincible growth flow] My brother was stabbed through the heart by his enemy in order to save me. Before he died, he asked me to take good care of my parents and protect my sister. But from that day on, the entire Gu family felt that I had killed my brother. My mother hated me to the core, and my three sisters regarded me as an enemy. All the thoughts they missed about their brother were given to another person. But I, the heir to the Gu family, have become the biggest joke of the Gu family. Until that day. For an outsider, they handed the knife to me with their own hands. It was also that day that I finally understood. Some family ties are not worth my life to keep. Some people are not worthy of letting me continue to give in. From now on. The genius of the Gu family, the martial arts monster, the heir to a hidden family... I no longer have to prove myself to anyone. Because when I reached the pinnacle of martial arts and took charge of the Gu family. They will eventually understand. What the Gu family really lost was never Gu Changkong. It was Gu Changyuan who Gu Changkong wanted to protect at all costs.
