Is Being a Master in the Modern World Really Safe?

After Sui An transmigrates to the cultivation world, he binds himself to the Dragon-Aotian System. As he levels up, the people around him look at him with increasingly strange expressions. He asks the System for help. System: [All fear stems from insufficient firepower. Host, you only need to become the strongest, and you'll have no more worries or troubles when it comes to relationships.] Sui An: Got it. After he devotes himself to cultivation and becomes the strongest under heaven... Those strange looks not only fail to disappear, they become even stranger. His fellow disciple, whose talent is inferior to his, is crushed by him at every turn.

Only Sui An didn't look down on his origins, taking him in and raising him from childhood. Under Sui An's earnest guidance, his little disciple grew up strong and healthy, honest and optimistic, never indulging in wine or women. But Sui An never expected that... After faking his death and leaving the cultivation world, he would return to the modern world, where spiritual qi had revived. A transfer student joined his class. The new student was gentle and mild, as emotionally steady as a capybara, and had many little habits just like his obedient disciple from back then. He always called Sui An
