I Deliver Express Delivery at Reiki Recovery

Zhou Xuan traveled to a world where spiritual energy was revived and gloriously became a courier boy. I originally thought I could just eat and wait for death, but I unexpectedly awakened the super express delivery system. As long as I deliver express delivery, I can get various rewards. I sent a courier to the instructor who was in class and explained the cultivation method. Send a courier to warriors who are addicted to cultivation, and give them some guidance to help them break through. Send a courier to the customer who is being hunted, and kill his enemies along the way. Delivering a courier to a boss who was in danger, he accidentally killed the ninth-level alien beast that was chasing him with a sword... The courier was delivering it, and Zhou Xuan accidentally became the strongest person in the world! Some people respect him as a holy master, some say he is a top ace killer, and some call him a master of swordsmanship. However, when faced with these titles, Zhou Xuan always smiled slightly: "Actually, I'm really just a delivery boy." This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
