The ghost slaves were the ghost king's protective talisman. There were only eight of them in total, and they were practically protecting the ghost king.
Perhaps in this world, there were less than five people who knew about the existence of the ghost slave, and only tie si Jiao and Qin Yu Yan knew about it. Others might not know about it.
In fact, even Li Tian himself had only seen the ghost slave once.
It was also that time that had left a deep impression on him.
He remembered that the ghost king had gone to a country to purchase a very special medicinal herb, but he had been discovered by accident. For people like the ghost king, they would either please him or kill him.
It was obvious that this country was not on friendly terms with the ghost king. They had sent out the entire country's Secret organization to attack the ghost king.
At that time, Li Tian was nearby. After the ghost king noticed the problem, he contacted him and asked him to come over.
