In Battle Through the Heavens, lying down makes you stronger.

In the world of Doupo, Xiao Ran transmigrates and obtains the strongest "Lying Down and Doing Nothing" system, which allows him to level up by simply resting. Despite his incredible ability, he is often misunderstood by those around him, including his disciple, Xiao Yan, who is frustrated by Xiao Ran's laziness. As Xiao Yan faces numerous challenges and hardships, he begins to realize the true extent of Xiao Ran's powers, but the latter remains uninterested in exerting himself. When a catastrophe unfolds at the Soul Emperor's battle with the Flame Emperor, Xiao Ran's sudden appearance in the midst of the chaos sparks curiosity and concern among the powerful figures present, including the Elder of the Soul Palace and Gu Yuan.
