About this book

A tournament of young Underlords is approaching, with great clans and sects around the world preparing their disciples to compete. The Blackflame Empire's youth are not yet strong enough to participate, so the Akura clan places the empire's elites in a specialized training ground where advancement is faster and more rewarding. Lindon and his team seize this opportunity to gain everything they can from the experience, though doing so creates new rivals. Only those who reach Underlord will emerge as winners.
