Why did Uncle Yang bury himself in the tent?

As the old sheepskin became more and more ill, he lied to Hu Bayi that there might be yellow leather to retaliate after his death, so he asked Hu Bayi and others to bury himself according to his method. But after the old sheepskin was buried, Hu Bayi found something was wrong, so he dug up the place where the old sheepskin was buried in time, and because of the funerary objects buried with Long Fu and Wong Tai Sin, there was yellow leather to rob it, and because of the lunar month in Long Fu, it attracted thunder fire, which led to the old sheepskin and yellow leather being hit by thunder fire! It is reported that in the novel "Ghost Blows the Lamp to Yellow Skin Grave", Chen Man, a blind man, speculated that the old sheepskin might have seen a vision in the white rock cave, and learned about the Yuan Sect dragon sorcery of burying naked bodies upside down, so he swallowed the bronze Long Fu, a feng shui secret weapon, so that this sorcery could be used as a dragon god to bless future generations. But the old sheepskin didn't accumulate that virtue, but wanted to go against the sky after death. After all, people are not as good as the sky, and finally there is no dragon. Although the technique is exquisite, the bamboo basket draws water with a sieve in the end. On the one hand, he was bound by his son's silks, on the other hand, he was dug out of the ground and struck by lightning. It is doomed in the end.
