Lin Jin, a border guard, died for his country in a border conflict. When he woke up, he traveled to a world of cultivation and became a guard at the wilderness border. What's even weirder is that he has a "border defense system" bound to his mind. As long as he guards the border and kills invading enemies, he will become stronger.
The first task released by the system was actually: "Looking for the lost wife: Mu Qingxue." According to clues, his nominal wife is actually thousands of miles away in the world of cultivation, and may she be the famous and aloof "Liyue Sword Immortal" today?
On one side is the wilderness borderland where wars are raging and demons are invading. With the support of modern tactics and systems, he has repeatedly performed extraordinary feats and become the "Fire Guard" who scares the enemy. On the other side is the ethereal and out-of-reach Immortal Gate of Cultivation. She has a clear sword heart, but due to an unresolved mortal relationship and stagnant cultivation, she is forced to go down the mountain to join the world and slay demons, but she does not know that the "opportunity" she is looking for is the garrison at that gate.
When the war broke out again at the border and hundreds of thousands of demon soldiers were pressing down on the border, she was ordered to come to help and saw that figure at a glance among the thousands of troops. He smiled and asked, "Have we ever met this fairy?" The fairy sword in her hand buzzed, and her heart rippled: "I am very familiar with your sword."
