There's an error in one of the chapter. for an example the miao clan young master bought a 4th realm demonic beast with a high bid 50k. But then on the latter chapter it was changed into a 5th realm demonic beast which is a mistake since the 5th realm demonic beast is rare and Lin mo gave the 5th realm demonic beast to Du clan by auctioning the 4th real demonic beast which the miao clan young master bought.
