"What are you doing?" Jiang Yuan's muscles tensed. He would take action against Shangguan Ya if there was the slightest disturbance outside. Only by controlling her could he survive in the vast Northern City Alliance.

“We need a pledge of cooperation!” Shangguan Ya’s swivel chair tilted slightly to the side as she reclined and pressed a button on the remote control. A projection was then displayed on the screen behind her.

"Before the beast tide besieged the South City, our people discovered the ruins of an unknown civilization, which contained a large number of things that current technology cannot understand. Today, the excavation of that ruin has reached its final stage!"

On the screen was a magnificent palace, a civilization unlike any other on Earth, and at that moment, Shangguan Ya was pointing a laser pointer at the palace's gate.

"Is this site outside the city?" Jiang Yuan realized that the time Shangguan Ya mentioned must have been quite early, and thinking about it, it could only be possible outside the city.

“Yes!” Shangguan Ya nodded, but before Jiang Yuan agreed to cooperate, she remained silent about the specific location of the palace.

"What do you want us to do?" Jiang Yuan couldn't understand this woman's thoughts. If it really was the ruins of an unknown civilization, would Shangguan Ya really be so willing to cooperate with them?

Something unusual must be going on!

"The Northern City Alliance originally organized an 18-person scientific expedition team, plus a reinforced platoon of combat personnel, with the aim of figuring out the connection between the unknown civilization and the catastrophe!" Shangguan Ya pressed the remote control, and photos of the 18-person scientific expedition team and several officers of the reinforced platoon appeared on the projection screen one after another.

"These are the people who went missing the day before yesterday!"

After all the photos were projected on the screen, Shangguan Ya said in a deep voice.
