A slightly urgent knocking sound echoed. Inside the office of the head of the Kaidan Countermeasure General Bureau's Investigation Team, Wu Qing frowned slightly while approving documents. However, after glancing over the table to ensure there were no confidential files, he finally said,
"Come in."

"Captain Zhou, what brings you here?"
"Old Wu, it's an emergency mission; we need to use your department's channels in the Eastern Country!" Captain Zhou spoke quickly. Wu Qing was taken aback for a moment before realizing the seriousness and his expression immediately turned grave.
"What mission? What do we need to do?"
