This process would take some time. 12 billion was not 1.2 million. With so many people, it would take a long time even if they were released. In addition, they needed to organize the team. So, it took Zhao Hai and the others five days.
Five days later, when melgen had finished organizing her team, Zhao Hai and the rest set off. In just a moment, Zhao Hai and the rest appeared in the sky above soul weapon city. The one billion undead slowly appeared outside soul weapon city, surrounding the entire city.
Zhao Hai's group's huge commotion naturally could not be hidden from the jilbenh brothers. The two of them immediately noticed Zhao Hai's group and the increasing number of undead outside the city.
Their expressions changed. A wave of mental power swept out and mobilized the entire city's Army. At the same time, they activated the magic array and prepared to defend against the enemy.
