Bleach: Traveling Through Byakuya, Ichigo Becomes Stronger by Torturing Him

He accidentally traveled to the Shinigami world and replaced Byakuya Kuchiki. He was about to face Ichigo Kurosaki, but what if he didn't inherit Byakuya Kuchiki's fighting experience? Fortunately, he obtained the system, and he could become stronger as long as he defeated his opponent. Looking at Kurosaki Ichigo, who still didn't know the true name of the Zanpakuto, Byakuya Kuchiki showed a strange smile. Kurosaki Ichigo: "I don't know why, but Kuchiki Byakuya is always a little stronger than me. How can I defeat him?" Zaraki Kenpachi: "Kuchiki, come and fight, I will definitely beat you today!" Aizen: "How is it possible? How could he kill me?" Yhwach: "Although I proposed the five special battle powers, Kuchiki Byakuya has surpassed the five battle powers. He is my lifelong enemy!"
