Stray Cat Strut [Stubbing Never - lol] - Foreword by the Author

Shao Xuan joins a friend in his expedition to a recently discovered archaeological cave. After he picks up an ordinary looking stone he is teleported to a different world and wakes up in the body of a small orphan child. The world he is in now is still in its stone age with primitive tools made of stone and the ways of the people are savage. Savage isn’t the only thing special about the people though, because they have superhuman strength, jump higher than trees and punch stones. In short, they are able to cultivate their bodies. Despite all this, it is a real struggle to survive because of the scarcity of food. Together with Caesar, his pet wolf, he tries to survive in this cruel world.

- Description from novelupdates

The world was once at war with 10 alternate worlds. This was known as the Concept War and our world won 60 years ago. All of this was concealed so no normal people are aware of this fact in the current time.

After the death of his grandfather, the high-school student Sayama Mikoto is suddenly summoned by the giant corporation IAI. He learns this world is headed for destruction due to the acceleration of the Minus Concepts. To prevent this, negotiations must be undertaken with the survivors of the other parallel worlds so their 10 concepts can be released.

And so Sayama is caught up in the final battle to clean up after the Concept War which left behind so much enmity.

Lynn embarks on a fantastical journey to a realm reminiscent of medieval Europe, yet infused with extraordinary magical abilities. Here, the very fabric of reality is governed by the enigmatic theory of magic, which harnesses and manipulates fundamental particles.

However, when Lynn arrives, a harbinger of an otherworldly Renaissance, the tides of change are set in motion, unveiling a thrilling tale of discovery, intrigue, and the struggle for enlightenment.
