Pen Pal Empress, Milk Me to Become the Supreme King

"Cultivation as an immortal is too difficult! Who can lend me fifty spiritual stones to help me in an emergency?" Qin Fen, the abandoned son of the sect with rubbish qualifications, stuffed a complaining letter into his mailbox at the most desperate moment in his life. Unexpectedly, this letter appeared in front of the anxious and panicked Empress of the Immortal Realm. The empress looked at the straightforward request for help, and her heart, which had been calm for hundreds of millions of years, actually felt a little ripple: "Interesting, I am bored, so raising a trumpet seems to be fun?" So, the empress replied. With a few drops of immortal beast juice, Qin Fen broke through on the spot. Qin Fen challenges geniuses from all walks of life with a book of immortal skills. From then on, Qin Fen's life style changed drastically. He writes letters when others are doing hard work, he writes letters when others seize treasures, he writes letters when others are close to death... He is writing letters of thanks to the boss. Let's see how a good-for-nothing boy becomes the Supreme Being of all worlds by the empress far away in the fairy world with the help of a mailbox!
