[Slow burn + no System + no harem + not a power fantasy; a wuxia/cultivation/fantasy world, proceed with caution if these aren't your thing]
A spiritual qi revival in a wuxia world (perhaps?)
While everyone else is still caught up in the turbulent jianghu of the martial world, the protagonist has already embarked on the path of cultivation.
In the arena, a martial arts master thrusts a divine weapon at his opponent. Then comes a clang, and the weapon snaps in two.
On the battlefield, as two armies face off, a transcendent being suspended in the sky interrupts them. One finger falls,
“Boom!”
Countless bolts of lightning writhe like silver serpents, unleashing devastating power upon the battlefield below!
The jianghu is still close, but the road to immortality is closer. Flashing blades and armies clashing with swords and spears fade into insignificance before the power to move mountains and fill seas...
When cultivators crush the martial artists’ world of fists and feet, when one person’s army breaks through the ranks of thousands of armored soldiers, when supernatural power overturns the established order of the mortal world, heaven and earth are transformed, and the world becomes a different place.
A young man leaves the green mountains and enters this turbulent, chaotic world. He seeks the righteous path, beholds heaven and earth, and bears witness to the human heart...
Nice. !!!
