Catching a Turtle in a Jar

"What is this thing?"

"What happened?"

"When did this wall appear?"

When the people of Ping City woke up, they realized that there were four tall white walls outside the city wall. These four white walls seemed to reach into the clouds and surrounded the entire Ping City in the middle, turning the originally very wide Ping City into a small box.

The people inside could only see the sky above the city wall. As for the sky outside and the land, they could not see anything.

The humans, who were originally calm and composed, finally felt a trace of fear.

"When did they erect these walls here?"

"What's going on? Where's the City Lord? The City Lord must have a way, right?"

"I believe the City Lord and the Sword Immortal will definitely have a way!"

But there were other voices. They ran everywhere, shouting.

"It's over, it's all over!"
