The Path to Immortality Begins with Mastering the Coffin Board

Unfair version: After waking up after rebirth, Lin Yu found that he was in a coffin. Before he could draw a circle and curse Heaven. He discovered that this coffin was actually left by the last emperor in the world, the Thunder Emperor, and it was made from the eternal soul tree, the most precious treasure in the world. Get rich! But the next second, a sky-devouring demon dog jumped out of the coffin. This is a heaven-level spiritual beast. Kidnap, kidnap, kidnap! From now on, with the emperor's coffin in hand, I own the world, and with the devil dog at my side, who can compete with me? Countless years later, the dark history of God Emperor Haotian slapping people with coffin lids and letting dogs out behind closed doors was left in the world. Serious version: Why do natural spiritual objects have strange auras? What is hidden in the dark world? Who is the real culprit in the conspiracy that happened thousands of years ago? Why are there only saints in the world, but not emperors? All the mysteries were slowly unveiled due to a journey to find water.
