Immortality Starts from Crossing Wu Dalang

Due to overwork, Wu Lang, who had worked overtime for 5 consecutive days and 16 hours in a row, died suddenly in his sleep when he returned to the rented cabin. Wu Dalang wakes up and travels back to the prosperous dynasty. Wu Dalang is a short dwarf who makes a living by selling cakes and is married to a lovely wife Pan Lian'er. At this time, Ximenda and Pan Lianer had hooked up. Just as the two were plotting how to poison Wu Dalang, Wu Lang, who had awakened the immortality system, smiled innocently: "Don't be afraid, I will be very gentle!" The little black dog is barking next to me. Yes, the owner is very gentle! [This is the first time for a female author to write in this genre. Please give me some pointers, thank you~]
