According to Zhang Zhanren's understanding, the Blood Sacrifice Formation in Ninety-nine Dragons City was more than ninety-nine percent complete. There was only one last step left before it would succeed.
In other words, the three holy fire emissaries were waiting for his message to be sent over so that they could complete the last step of the blood sacrifice array. Therefore, it did not take long.
It had been an hour since he sent the message to the three holy fire emissaries. The blood sacrifice array should be almost complete.
Once the Blood Sacrifice Array was set up, the three Sacred Fire Emissaries could activate the Blood Sacrifice Array and hatch the eggs from afar to kill Zhu Wuwan.
As long as Zhu Wanhao died, he would have completed this mission. Moreover, it was one of the more important parts of this mission, obtaining the resources and treasures to advance to the ancient giant.
