What! Am I the Only Local in a Different World? !

(Dark magic + dragon egg contract + mind reading to see through time travellers + Aboriginal counterattack cool article, what's wrong with me being the only local in the world? I still push the idiot to the ground and beat him!) Zeno lived for ten years before he discovered that the whole town was playing him—— The uncle in the leather jacket shouted "System Mall" into the air, turned around and smiled at him: "Kid, uncle is practicing tongue twisters." The sister in Hanfu said that "we use electric lights there" and disappeared the next day, leaving only a luminous jade pendant. The crystal ball was completely silent to him when he was testing his magic power, but the outsider was shouting in his heart: "Sure enough, the natives have no talent! I am the only time traveler in the world!" Until that day, he bumped into the obsidian dragon being chased in the dark forest. When he was so frightened that he peeed, the dark magic power suddenly exploded in his body, corroding the pursuers into slag. When he woke up, he had an extra dragon egg in his arms and signed a lifelong contract with him. When he reported to the Magic Academy, he thought he could finally get rid of these "drama queens", but at the opening ceremony he heard the voice of his new classmates: "Holy shit! Why does this native have a dragon? The system prompts that he is a dark type?!" I turned around and heard another tablemate: "Don't be exposed! Follow him closely, you will definitely win this time!" Zeno: "..." I am the only local in the world, and I have two time-travelers as brothers? Later, when he controlled the shadow that could swallow the Holy Light, rode on the back of a hundred-meter-long ancient dragon, and looked at the Pope and the system host being rubbed against the ground, he finally understood—— "You guys with hangings may have forgotten that this is my home court."
