Strongest Wife Guard

Even the Three Sovereigns and Five Emperors had to respect Lin Xuan. In order to fulfill a promise, he had to complete one of his Dao Fruits and ascend into the Windy City.
From then on, Lin Xuan became a berserker who protected his wife.
Was his wife in danger? Close protection. His wife was unhappy? Take it with you.
Any expert or cultivator would be lying on the ground in front of Lin Xuan.
