Infinite-Dimensional Summoning: Crimson Twin Tails

I simply transmigrated to an ancient world where martial arts reigned supreme.

Yu Yi originally planned to rely on characters summoned by his System to quietly work his way to the top, never expecting to reach his peak right from his debut.

One Crimson Sky from Aria, and a million-strong army was wiped out.

One Sword of the End from Tohka Yatogami, and an entire nation vanished without a trace.

Yet Yu Yi always thinks there are even more powerful experts in the world, unaware that the strongest ones are right by his side.
