Red Flags Stain the Immortal Heavens: Our Soldiers Beat Up the Cultivators

(modern military + cultivation + spacetime portal + war + science fiction + revolution + ensemble cast + awakening of the cultivation world's natives)

That day, a spacetime portal opened in China's southwestern hinterlands, and a feudal cultivation civilization invaded, treating ordinary people like ants.

Waiting for them was the steel defense line of the modern people's army.

We defend our homeland with technology and bring revolution to another world, helping the common people oppressed for ten thousand years finally stand up and live as human beings.

When a rigidly stratified immortal dynasty encounters a modern civilization that believes in the people, this is no simple war. It is the ultimate clash between two ways of life and two paths to the Dao.

A sword sweeps across the Nine Wastes; the red flag rolls up ten thousand layers of frost.

The old immortal laws and order are all swept away; the righteous path of the human world is forged through hardship.
