"What's wrong, mom?" Hua Bao, perched on Jiang Yan's shoulder, suddenly stretched out a vine towards the direction of Yunding Tower.
After staring for a while, he saw nothing unusual.
Retracting the vine and scratching his head in puzzlement, he said, "Mom, I didn't detect anyone or anything abnormal."
"It's nothing; I might have been mistaken," Jiang Yan took a deep breath to calm herself and picked up the telescope to look towards Yunding Tower again.
"Mom, are you talking about those planks nailed to the glass windows?" Hua Bao finally noticed something peculiar.
Jiang Yan clutched the telescope tightly and swept the entire building from top to bottom, her frown deepening, "Yes."
The part of the building exposed above the ground had its glass curtain walls completely covered with wooden planks.
At a glance, it was unusually eerie.
Jiang Yan had seen such reinforcement with wooden planks on buildings in television broadcasts before.
