Those four people were none other than the four sky kings of the Dragon Division!
Bei Shan's iron chains locked directly onto the legs of the two guest masters, and then the other three sky kings immediately shoved daggers into their chests, ending their lives.
As for the other 30 guards, there were 12 earth kings from the Dragon Division to deal with them.
Within 10 minutes, those guards were all on the ground. The Dragon Blades all stood at the mountainside and watched the chaos happening in the Ryong Family Valley. The J of Diamonds was a bit worried and said, "I don't know how our junior brother's doing right now."
Bei Shan looked at the Ryong Family Valley and faintly said, "It has been over 20 years of planning, yet today, due to his recklessness, we have to have a showdown."
The other three sky kings sighed, "Right now there are still 12 core members and 6 guest masters, it's going to be a bit difficult."
