White-haired Old Soldier: One Man Guards the Nation's Gate for Ten Years to Prove Himself Emperor

Upon waking up, Li Canglan found himself transported to a world of advanced martial arts where countless races were invading. Here, he became an unparalleled genius and a martial arts grandmaster at the age of 20. Unfortunately, during the invasion of countless races, Li Canglan led his men into battle, only to be besieged by them, resulting in severe injuries and his retirement.

Eighty years have passed in the blink of an eye, and Li Canglan has become a dying, white-haired old soldier.

His wife was killed by the myriad races because of that battle, and Li Canglan also suffered from injuries every day. Fortunately, his son was successful and he had grandsons and granddaughters, so his later years were quite fulfilling.

Just as Li Canglan was waiting for his life to end, the Billionfold Sacrifice System awakened, and he began his journey to the pinnacle of life.

[Ding! Sacrificing the Profound Rank Blazing Sun Technique, a critical strike of ten thousand times is achieved, granting the Supreme Nine Suns. The Nine Suns soar across the sky, scorching heaven and earth!]

[Ding! Sacrificing a low-grade Purple Sun Fruit resulted in a critical hit of ten thousand times, obtaining the supreme holy medicine, Purple Jade Divine Fruit!]

[Ding! Sacrificing the Earth-Rank War God Technique, a ten-thousand-fold critical hit was achieved, and the Battle Saint Technique was obtained!]

………………

Li Canglan thus lived a second life, continuing his invincible path from eighty years ago.

When all races invade, Li Canglan carries a blood-red coffin on his back, guarding the nation's gates alone, and suppressing the world with a flick of his finger!
