I Just Became an Immortal, and the System Asked Me to Do a Novice Task

Jiang He's eight hundred years to achieve the true fairyland shocked the heavens, but coincidentally with the invasion of foreign tribes from outside the territory, the fairy world was in chaos. Jiang He was faced with the choice of joining the war or retreating to the rear. At this moment, the system awakens and allows Jiang He to return to Novice Village. How should Jiang He make a decision... Thousands of years passed in the blink of an eye. In the human world where Jiang He was, there were as many Mahayana as dogs, and true immortals were everywhere. When the aliens invaded again, the Emperor of Heaven was forced to go down to earth in person and beg Jiang He for help. Jiang He just smiled faintly: "It doesn't matter, I will take action."
