Reborn as an Interstellar Pharmacist

After Luo Yu died, he discovered that he had been a cannon-fodder supporting character in a book. The protagonist of the book was his younger brother, Luo Su. Growing up, he had competed with Luo Su at every turn to win the approval of his family and everyone around him. In the end, he gained nothing, and only made everyone close to him hate him. Only after dying did he finally understand: as a vicious cannon-fodder character, his only role had been to serve as a foil and stepping stone for the protagonist. He had already accepted his fate, but unexpectedly, he was reborn. This time, he had figured things out. Forget being a cannon-fodder or a protagonist. Couldn't he just stay far away from all of it? He didn't want family or friends anymore. He wouldn't compete with Luo Su again. So when it came time to choose his major, he gave up on the mecha program Luo Su had chosen and instead enrolled in pharmaceutical studies, the field he'd always longed to pursue in his previous life. With his exceptional mental strength and the experience of his previous life, he was confident he could escape Luo Su's shadow and make a name for himself in this field. Gradually, he became well known. The medicines he developed had a purity of 90 percent and caused no side effects when taken. For centuries, no one had been able to surpass this achievement. The mental-strength medicine he improved could effectively ease mental instability. It was in such high demand upon release that even the military struggled to obtain it. It was expensive and nearly impossible to find. Years later, when he had become a grandmaster of interstellar pharmaceuticals, he looked back at the complicated expressions of those who had once hated and despised him, unable to hold a candle to him. By then, he no longer cared. The only person worthy of standing by his side was the Empire's God of War. Theme: No matter the obstacles, there is always hope
