After I Created the Myriad Worlds, Another World Invaded

Wu Hang unexpectedly obtains an ordinary crystal ball, only to discover that it contains a separate world.

Inside the crystal ball, Wu Hang becomes the creator, moving mountains, filling seas, summoning wind and rain.

With a few deft moves, he brings countless civilizations into being in his world: technological, magical, immortal, fantasy, mythological, and more.

But just then,

their home planet is invaded by another world, and the human alliance is routed.

With humanity on the verge of extinction,

an army united from countless worlds pours out of Wu Hang's body.

Invading army: "Pull back, now! This Blue Star alliance is made up of demons. We fight the tech troops, then the magic troops, and the immortal and fantasy troops are even more ridiculous. One sword strike, one punch, and they wipe out a million of our soldiers!"

Invading forces: "We thought we were facing the lowest-level life-bearing planet. Why does it feel like we're up against every race in the cosmos?"

The blurb doesn't do it justice. This book is also known as: I've Become the Creator of All Worlds, So Why Am I Being Invaded?, I Am the Creator of All Worlds! Building an Army of Transmigrators!, and I Alone Ascend Blue Star.
