At Ten, I Was Ordered to Guard the Border. Now I'm a Sword Immortal, So Why Are You Crying?

??? Wait, I'm only ten years old, and you want me to guard the border?

Gu Fengming transmigrates to an immortal martial world and becomes the illegitimate son of the old emperor of the Great Feng Dynasty.

The emperor dies and a new one takes the throne. By law, all noblemen's illegitimate sons within the Great Feng Dynasty must be sent to guard the human race's border.

The human border lies with the Hundred Thousand Mountains at its back and countless demon clans before it. Anyone sent there is all but certain to die.

Fortunately, his System awakens, and Gu Fengming obtains the Drunken Sword Immortal template, instantly becoming a Great Sword Cultivator of the Thirteenth Realm.

“One drink, and I drain the rivers. Another, and I swallow the sun and moon. A thousand cups can't make me fall, for I alone am the Drunken Sword Immortal!”

He guards the border at ten, slays a demon king at eleven, and shocks gods and ghosts at twelve...

When word of this reaches the imperial court, the empress is so frightened that she bursts into tears!
