This was how onmyōdō was defined in the Hundred Demons World.
The foundation of all onmyōdō was controlling the weather, and that was also its ultimate goal.
Wind, fire, thunder, lightning, clouds, fog, ice, snow, rain.
In other words, every meteorological change on a planet.
At present, only Abe no Yoshihira—the son of Abe no Seimei and grandson of Hagoromo Fox—had reached this level in the Hundred Demons World.
Yet during the four hundred years Abe no Seimei had spent as the Lord of the Underworld, he had raised the upper limit of onmyōdō once more.
He had mastered the ability to use gravity to control the orbital trajectories of planets.
He called it Astronomical Manipulation!
In the Human Realm, this ability could affect celestial bodies of all sizes within the solar system.
Although it had only a minor effect on large planets.
It could still alter Earth's gravitational environment.
Completely destroy human civilization on the surface and achieve the "purification" he envisioned.
Theoretically, he could even pull down a few meteors from the asteroid belt like Issho and precisely bombard any location on Earth.
Because with the Taiyi Liuren Divination Board in his grasp, he was the most precise "humanoid guidance system"!
But the Underworld had no Starry Sky, nor did it have a universe.
Naturally, Abe no Seimei could not use Astronomical Manipulation here.
However, he could use it normally within this Reality Marble, where mental landscapes could be materialized.

The next moment, he held his hands out before him, and a twisted, bizarre ring instantly formed between them. Within the ring was a chaotic dimension of alien space.
As Abe no Seimei's voice fell, an even larger bizarre ring appeared out of thin air above Imu's head.
Karna, Falcon Dragon, and Albertrion could clearly sense
