Reincarnated in Battle Through the Heavens, Helping Xiao Yan Become an Emperor

[Transmigration] + [System] + [No Harem] + [Decisive and Ruthless] + [The Path to Invincibility] After accidentally transmigrating to the Dou Qi Continent, Lei Ling was just one of the millions of descendants of the Lei Clan. That is, until he awakened a System at the age of fifteen. From then on, he cultivated the Nine Springs Returning Spirit Art, devoured Heavenly Flames and lightning, and made the acquaintance of Xiao Yan. Together, they dominated the Jiama Empire and eventually became emperors. But when he faced Hun Tiandi, Lei Ling was dumbfounded. Hun Tiandi: Bet you didn't see that coming! This old man has been reborn too! And this time, I brought backup! Lei Ling: I don't care if you're reborn or how many helpers you have. I'll scatter your ashes along with theirs!
