Canglan Tribulation: Sword Breaks the Sky

[Fantasy cultivation + genius flow + upgrade flow + multiple heroines + no system] There are many powerful people in Canglan Continent, and there is an undercurrent surging under a catastrophe. Ever since I was little, there is a saying that has always been lingering in my ears. "The weak punches the strong, and the strong punches the stronger. The greater the ability, the greater the responsibility." But I am not a powerful person who can change the world with a wave of my hand. I cannot be as compassionate and loving as a saint, protecting all living beings behind me. But I will follow my own path in my own style. I will practice my whole life just to protect what I cherish, but I hope to have a clear conscience and clear thoughts. Just a few decades after the Canglan catastrophe, the five regions were in turmoil. Let's see how the Fenghua young man was summoned to join the tribulation, how he could shake the world with one sword and become the supreme immortal emperor.
