Arthur had only walked about 100 meters since exiting the complex and he knitted his brows, glancing back briefly.
"What's wrong?" asked Carla and Bella simultaneously.
Arthur didn't answer, but shook his head with a wry smile.
This was something he hadn't expected, the woman was following them.
"Let's go this way," he said, stepping into a narrow alley between two three-story buildings.
After arriving there, he jumped onto the wall of one of the buildings and then onto the wall of the other building.
He kept repeating the movement until he reached the top of the building.
Carla and Bella were dumbfounded and confused by his sudden movements.
They wanted to ask but Arthur was already too high above.
In the end, they looked at each other.
"I don't think it's that hard to do," Bella said.
"Can't you just use your wind power?" asked Carla.
"It's hard if it's too high, I'm afraid I'll lose control and fall." Bella shook her head.
