Immortality, I Can Upgrade All Things Entry

Lin Xian traveled across the deserted continent and unexpectedly discovered that he could upgrade the entries of all things! Many years later, a powerful Nascent Soul came to Lin Xian with humility and said: Please ask the Immortal to add a one-hit entry to his magic weapon. I am willing to buy it with 100,000 spiritual stones. Lin Xian pointed to the back: Queue up, there are still a dozen people waiting outside in the transformation stage.
