The Top Student Is a Total Badass in a Fight

In fact, I have a conjecture that the elder brother and younger brother are reincarnations themselves. First of all, the younger brother was in poor health. The older brother was like a god of learning. He tried many methods and was reborn many times, but he just couldn't save his younger brother. In the end, he paid a heavy price. He would die at the age of 18, and he would be in a state that he could not learn in many places. He saved his younger brother in one reincarnation, but the younger brother couldn't accept his brother's death. He also followed his elder brother's example and reincarnated countless times to find a way to save his elder brother. The elder brother also had an unparalleled talent in pharmacy because of his obsession with his younger brother's illness.

Brotherly love is warm and reassuring
