He is a legendary soldier king who made the world tremble, but he lost his memory during the mission and became the "contract husband" of an ordinary single mother and the "father" of his cute four-year-old child. When bad luck came and his wife and daughter died tragically because of him, he woke up in blood and fire, but it was too late. Time gave him the cruelest mercy - to return to the seven days before the tragedy. In this life, Lu Yanluo returns with the power of the God of War and endless regret. While uncovering the lurking deadly threat, he must learn to be a true father and lover. Faced with his wife's alienation and distrust, he embarked on a journey that was more difficult than any battlefield: chasing his wife clumsily, protecting his cute baby, and in the cyclic countdown, using his life to atone for his sins and win back the ordinary happiness he had missed.
