Extraterrestrial Stars? No, That's My Elixir

On the day of the college entrance examination, Chen Xian suddenly rushed out of the examination room. Under the astonished eyes of the invigilator and classmates, they kept looking at the sky and laughing wildly: "It's done, hahaha~ Master Dao is finally done!" Facing the teacher's criticism, you didn't care and still laughed wildly: "I finally refined the stars from outside the territory into a golden elixir!" "From now on, I am the only one in heaven and on earth!" Not surprisingly. You were put in a mental hospital... Because the incident was so bizarre, it became a hot topic and attracted a lot of ridicule. I thought that was the end of the matter. However, seven days later, countless powerful and terrifying extraterrestrial demons tore through the void and invaded Blue Star. When everyone was in despair, Chen Xian transformed into a powerful man in the Golden Core realm and descended into outer space. The Ten Thousand Soul Banner in the left hand and the Human Emperor Sword in the right hand. Behind him is a star-level golden elixir. He was frantically chasing down extraterrestrial demons that were several levels higher than him. The demons outside the territory couldn't stand it any longer: "Killing a strong Nascent Soul is like killing a chicken. Do you call this the Golden Core Realm?" "Blue Star is so scary, I want to go home!" … Chen Xian: "What? You are only allowed to invade Blue Star, but I am not allowed to invade outside the territory?" "Look at my Ten Thousand Souls Banner!!!"
