National Destiny: an 80-Year-Old Veteran Goes to War, Guarding the Country Alone

There are only three points left in Daxia's national fortune. Another defeat, and 1.4 Billion people will be wiped out along with the entire civilization! The hell-level hunting ground for thousands of people was opened. The sky did not select two S-class experts. Instead, it appointed an eighty-two-year-old retired man with 27 old injuries and a crutch to walk - Gu Changsheng. Countries reveled in revelry, and Great Xia was in despair. No one knows that he once had a top-secret code name - "One Man Great Wall"; no one knows that the only national sports auxiliary system that has been dormant for seventy years has been reactivated in his mind. Break black rocks with one punch, kill ferocious beasts with one stick, and cut through canyons with one knife! When thousands of tribes pressed against the country and powerful men from all countries joined forces to attack, Gu Changsheng stood alone in front of the country's gate: "Seventy years ago, I guarded it." "Today, the national gate will still not be breached!" It wasn't until this moment that the whole world understood—— What Daxia sent was not an old man, but a Great Wall that had lived for eighty-two years!
