Cui Heng crossed over, and the system told him that this is a world of high-level immortals. Immortal kings roam freely, fierce beasts are everywhere, and if the powerful people disagree with each other, they will explode the galaxy and destroy the world, which makes him tremble. He provided a 300-year protection period for novices. As long as they are in the protected area, they will not suffer any harm. So, Cui Heng started the 300-year journey of cultivating immortals. During these 300 years, people have entered here by mistake one after another Some come from humble backgrounds, have worked as monks and beggars, but have great ambitions to bring order to the world and save the people. As a princess, she only wants to find her elder brother, not to become a fairy, but to wait for him to return in the world of mortals. Some are weak and sick, but they dream of going to the world, hoeing the strong and helping the weak, and becoming a generation of chivalrous women......... Cui Heng is based on making friends The mentality of kindness gave them a little bit of help. Three hundred years later, the novice protection period of the system ended, and Cui Heng finally made his golden core, and walked out with a trembling heart. Only to find that this place is actually just a world of martial arts!
