Back then, Serka also wanted to go to the Genius Battlefield, but due to his astonishing talent, he was directly noticed by a Star River level figure and accepted as a disciple. This was a huge news event at the time, and his family benefited greatly from it, elevating the entire family to a major family.
That's why he mocks Jia Yan for possibly being so arrogant because of the Genius Battlefield.
