After Ten Years of Guarding the City, I Was Slandered, and I Left the World in Panic?

Aquamarine, Arctic alien invasion. Humans around the world have awakened their supernatural powers and built ice cities to fight against it. Zhang Hao traveled through time to represent China, guarding the Arctic Ice City while signing into the immortal cultivation system. Ten years later, when he was about to achieve the invincible cultivation level of the Immortal Emperor, he was slandered all over the world. Slandering him as the lord of Ice City, who has not killed all the aliens in ten years, is secretly talking with the aliens to betray them, with the intention of betraying all mankind. Those who slander China's superpowers are just being foolhardy and focusing on seizing power. Suddenly, Zhang Hao and Hua Xia lost all their prestige and were suppressed. Zhang Hao was heartbroken by the dead Chinese superpowers and voluntarily resigned from his position as Lord of Ice City. In order to protect Zhang Hao, China also voluntarily withdrew from the Global Association of Superpowers. Free countries, island countries and other countries were overjoyed and arrogantly declared: "Without Zhang Hao and without Huaxia, we will have less burdens and can wipe out all alien races in one month!" But only half an hour later, other countries around the world began to panic: "What's going on? Without Zhang Hao to guard, Bingcheng will be lost so soon?" "Ah? In just one hour, tens of thousands of people died in the United Superpower Association? When Zhang Hao was here before, why didn't he realize that these aliens were so powerful?" Immediately afterwards, in just three days, the aliens invaded the west. In just half a month, the alien race conquered more than a dozen medium-sized countries. In just one month, major countries such as free countries and island countries were in emergency. ... Huaxia, which was only guarded by Zhang Hao, made the foreigners frightened and did not dare to approach. Everyone regretted it and knelt in front of Zhang Hao in the border town of Huaxia, crying in panic: "Zhang Hao, Huaxia, we were wrong! Please, save us!"
