"The Fourth Killing Formation?" Zhu Xuan Er asked in astonishment.
"According to the legends, there are spirits in heaven and earth that form ten natural killing formations," Ling explained. "The ten killing formations are all extremely terrifying. The Second Killing Formation to the Tenth Killing Formation can even wipe out Shattering Void Tiers."
"Then what about the First Killing Formation?" Zhu Xuan Er couldn't help but ask.
"The First Killing Formation...?" Ling Han paused. "It's also known as God Killing Formation!"
"Could it really kill gods?" Zhu Xuan Er cried out.
"That's right." Ling Han nodded. "The First Killing Formation can erase even gods—the world's greatest killing formation. However, knowledge of formations was lost, so who could set up such a killing formation now?"
