AI Sent a Courier to Cultivate Immortality

Su Yunfeng couldn't help but smile, "Cultivating immortals? Isn't that all in novels?" "Not really." The old gentleman turned around and took out a book that was so old that the color had faded, and handed it to Su Yunfeng, "With this "Wandering Immortal Sutra", if you are willing, maybe you can get a glimpse of a corner of the world." Su Yunfeng took the book, and out of respect for the old gentleman, he did not refuse immediately, "Okay, I will take a look, thank you."
