At 100 years old, he joined the army in place of his granddaughter, and became a national war god.

Su Mu transmigrated into the body of a centenarian. In a time of war, his wife and son were all killed by foreign enemies, leaving him and his twelve-year-old granddaughter to depend on each other. He originally planned to raise his granddaughter and live out his old age in peace, but then the government conscripted soldiers and wanted his twelve-year-old granddaughter to join the army!
"One for each household, or I'll burn them all!"
Seeing that his granddaughter was about to be taken away, Su Mu, leaning on his cane, stepped forward.
"I'll enlist in the army in my granddaughter's place!"
The room erupted in laughter. A centenarian going to join the army? He'd be more like sending himself to his death!
Little did anyone know that while everyone was laughing at him, Su Mu had already awakened the [Centenarian War God System] and accepted the mission to join the army.
On the battlefield, this centenarian veteran went berserk!
An arrow pierced the clouds, and the enemy commander-in-chief was killed on the spot!
One man, one gun, taking the enemy general's head amidst a sea of ​​soldiers!
One man defends the city, intimidating an army of 100,000!
The enemy troops were terrified: "Never mess with that centenarian!"
The emperor personally greeted him: "Elder Su, how many years have you lived?"
Su Mu smiled faintly: "I'm a hundred years old this year, I can still kill for another fifty years!"
From then on, the centenarian veteran swept across the battlefield, turned the tide of battle, protected his home and country, and fought his way to become a national war god!
