A Hundred-Year-Old Veteran: From the Start, I Slay a God and Shock the World

A hundred-year-old veteran heads to the battlefield. Is this a distortion of human nature, or a collapse of morality?

Xu Xinghun transmigrated to a parallel world and became one of the first soldiers to defend against gods and demons. Unfortunately, he had only average talent and no glorious deeds to his name.

Then, one day, the gods and demons invaded.

Humanity's armies were easily destroyed, and countless martial artists were killed or wounded.

At this moment of life and death, an old soldier carrying a three-foot saber appeared before the world.

Just as he had in the past, Xu Xinghun stood resolute.

Old soldiers never die!

Their heroic spirits live on!

Xu Xinghun struck just once, and the gods and demons vanished.

The world was stunned.

After killing the gods and demons, Xu Xinghun was shocked to discover a strange voice in his mind.

Ding! System activated.

The System that was a hundred years late had finally activated?

Xu Xinghun was at a loss.

Why the hell hadn't the System shown up sooner?

Even more shocking to Xu Xingye was that his grandson was actually the protagonist, and had a System too?
