The Eternal Supreme, Li Yunxiao

Once hailed as the third-strongest expert on the Tianwu Continent, Martial Emperor Gu Feiyang found his cultivation trapped at its peak by the very laws of the world. To break through his limits, he orchestrated an audacious plan, sacrificing everything to reincarnate and begin anew. Reborn as Li Yunxiao, a fifteen-year-old heir of a powerful military family in the Kingdom of Tianshui, he finds himself caught in a storm of invasion, royal succession struggles, and political intrigue. While others fight for power and status, Li Yunxiao sees the bigger picture. Armed with the wisdom and experience of a former Martial Emperor, he calmly overcomes every obstacle on his path toward a single goal: completing the grand design he began in his previous life and laying the foundation for true godhood.
