Battle Through the Heavens: I Became a Fellow Disciple of Xiao Yan, the Strongest Supporting Character

【Transmigration + System + Invincible + Thrilling + Overwhelming Might + Playing the Fool to Catch the Tiger】 I woke up one day in Battle Through the Heavens, having transmigrated with a System. I grew up alongside Yan Di and Xun Er, as close as brothers and sisters. After awakening the Ultimate Supporting Character System, I learned its purpose was to stay by Xiao Yan's side and help him become Yan Di. With the Dou Di Bloodline, I became Yao Lao's disciple and won the Queen's heart. One Flame Lotus and one long sword, two brothers roaming the continent together. When Heavenly Flames appear, all other flames submit; When the Star-Slaying Sword emerges, ten thousand swords follow! Above Zhongzhou, the Flame Lotus lays waste to all; When the Seven Kills strike, who would dare disobey? This story is all about companionship. I'll find opportunities of my own without stealing the original protagonist's chances, and ultimately become the strongest beneath the Dou Di realm! Watch me write my own legend and forge a different kind of Battle Through the Heavens!
