Standing in the center of the ruins of the ancient Roman Colosseum, Li Zhang heard the sound of a roaring crowd like a mountain and a tsunami, with blood splattering and limbs flying. However, Li Zhang's heart seemed to have experienced an unprecedented baptism. Suddenly, Li Zhang turned his head and looked to the east, looking through the crowds and through the lively Roman market. There was a wave of waves in the place now called the Vatican, which plucked Li Zhang's heartstrings. He knew that he should leave, because of love and pursuit of the limit. He was leaving without any hesitation.
