Jiuhuan Xuantian, ten thousand years of immortal rule.
The world believes that flying with a sword is the orthodoxy of the Tao. When monks are defeated in a battle, they jump on the sword and escape into the air. They can travel thousands of miles in the wind and think that it is difficult for ordinary people to catch up. But there is an unexplored iron law of heaven and earth hidden in the law of balance of spiritual entropy: casting spells in the air will continue to overflow free spiritual energy, and the spiritual energy accumulation exceeds the standard, which can range from the collapse of the cultivation base to the tearing of space and triggering disasters in the world. The collapse of ancient civilization was a catastrophe of spiritual entropy caused by uncontrolled flying in the sky and cultivating immortals.
The protagonist, Shen Yan, was born without spiritual roots and could not absorb half of the spiritual energy, so he was regarded as a useless person by the sect and was expelled. Only by awakening the unique "spiritual entropy perception" can he capture the spiritual energy floating in the air, transform ordinary iron firearms, and use the escaped spiritual energy to forge spirit-killing bullets. The higher the monk flies and the crazier his escape skills become, the more spiritual energy leaks out of his body, and the power of the sniper rifle in his hand increases several times.
The elder of the Qingyun Sect was defeated, and subconsciously stepped on his sword and took off into the air to escape, threatening to escape for thousands of miles and no one could stop him. A modified Barrett was set up at the top of Shenyan Mountain, and a shot to the head from 10,000 meters away caused the streamer to fall suddenly in the air. Since then, Xuantian Continent has established an unwritten air ban: monks must never dare to take even a step in the air when fighting.
On one side is the old-line Immortal Sect that adheres to the sword-controlling tradition and controls the power of the sect. Their main plan is to abolish the air ban and kill the "Lord of the Spirit-Eliminating Spear";
On one side are innovative monks who have clearly seen the disaster of spiritual entropy and advocated spiritual weapons to control spiritual energy. They want to unite with the mortal world to establish a cross-domain Hengtiansi;
Furthermore, a rift in Blue Star opened up, and modern military technology flowed into Xuantian. The civilizations of the two worlds spied on, competed with, and checked and balanced each other.
