The day of departure...
Leng San dispersed some of his gold coins to the five branches of the Azure Dragon Sect all over the martial world and had the former elders of the Beastly Devils Society, who were now the Supreme Elders in each branch of the Azure Dragon Sect, take care of them.
Another part was kept within the treasury of the Fortress of the Sea God, overseen by his two wives, because when he went to the other realms, these coins would be worthless.
For the Sky Viper, Leng San had sent her to be with the old snake because he did not want her to risk danger with him. As for Mr. Black, after all the years of good care combined with his increased knowledge, Leng San could cut off the connection between the dragon and the Beast Spirit Sign at the last moment before he left.
