The System Arrived Early, and the Security Guard Said I Was Slaying a Dragon?

Lu Fan traveled through the world of martial arts. This world entered the era of cultivation hundreds of years ago. Unfortunately, Lu Fan's qualifications were mediocre. He had only been at the second level of Qi Condensation for two and a half years. In this case, Lu Fan directly chose to avoid the detour of his life for thirty years, applied for a job as a security guard at Linhai Martial Arts University, and entered retirement mode. At this moment, the golden finger, which had been delayed for several years, finally arrived, but before Lu Fan could be happy, he discovered... There seemed to be something seriously wrong with the system! Alarm! Danger! A third-level mutated star beast, the bloodthirsty mosquito, has been detected near the host. The host is too weak. Please run away for the sake of your own life! Alert! Alarm! Looking at the blood-sucking mosquitoes flying in the security room, Lu Fan fell into deep thought. When Lu Fan wiped out that hateful blood-sucking mosquito with one click... [Host... The host is awesome! With the second level of Qi Condensation, cross two realms and kill the third level star beast, the bloodthirsty demon mosquito, and be rewarded with a hundred years of cultivation! Reward the prototype of Sword Intent! Reward swordsmanship and open up mountains with one sword! Next, the system's more outrageous prompts appeared one after another, a patterned spider, it must be a fourth-order mutant star beast, a loach that fishermen often use to make nests... It must be a fifth-order dragon! As time went by, Lu Fan gradually understood that his system... Seemed to be three hundred years early? ! All the mutant beasts with extremely vicious reputations have not grown up yet! Lu Fan looked at the "fifth-level dragon" twisting in his hands with a serious look on his face. "In that case... Then I will fight with you mutated beasts who will cause harm to Blue Star in the future! Today we will not only distinguish between superior and inferior, but also decide life and death!"
