"But I really don't know how these people got into the imperial city."

“One or two is fine, but there are seventy-nine people.”

Gu Jiangli sighed softly.

The emperor was deep in thought about the same question when a childish voice broke between them.

"Your Majesty, Your Majesty, I understand."

Gu Jiangli turned around and found that Chen'er had been standing beside him for a long time, and he had probably heard everything he said.

She asked with some doubt, "What does Chen'er know?"

Chen'er's dark pupils shone with confidence and composure as she answered:

"Do you know how they got into the capital?"

The emperor's expression became extremely serious.

"What do you mean by that, Chen'er?"

Chen'er took two steps forward, and the emperor scooped him up onto his lap, making Chen'er the same height as the two of them.

He took out a piece of white paper with simple architectural drawings on it. The simple lines clearly indicated that Chen'er had just drawn it herself.

He pointed to the pattern and said:

"Father, Mother, it's actually very simple. Look here, this is the map of the outermost guard perimeter of the entire imperial city."

“There is only one entrance between the Imperial City and Deer City,” he said, pointing to the upper right corner.

Then, he pointed to several other locations and continued:

"These locations are the various sentry posts on the imperial city wall. After the city gates are closed, the soldiers will stand guard at these places."

"Because these are outposts, a small wooden pavilion, taller than the city wall, will be specially built in these places."

“If the bandits were smart, they would understand that stone walls are difficult to pierce with flying claws, but wooden ones can be.”

“At the hours of Chou (1-3 AM) and Wei (1-3 PM), the officers and soldiers would take turns changing shifts, which means there would be a few brief moments when there would be no one on the sentry post.”

“It’s broad daylight at the hour of Wei (1-3 PM), so they dare not make a move.”

"But the hour of Chou (1-3 AM) is when the night is dark and the wind is high, and the officers and soldiers are also very tired."

"As long as you seize this opportunity, use the grappling hook to firmly grip the sentry post and slowly climb up."

"They might just stay clinging to the city wall, waiting for the soldiers on guard to doze off and then attack. It'll be a matter of two punches, and everything will be fine."

Chen'er spoke fluently, as if he had personally witnessed how these people used this method to enter the imperial city.

Then, pointing to a spot, he said:

"Your subject believes that they must have entered from this sentry post. There is a small grove of trees outside, which would allow them to hide even during the day."

"This is a corner, perfect for hiding. When the hour of Chou (1-3 AM), they will use their flying claws to climb the wall."

"Because we have to wait until the officers and soldiers get sleepy, we will definitely have to stay on the city wall for a while."

"But as soon as the officers and soldiers get sleepy, we can launch a direct attack and catch them off guard. It will be easy to re-enter the city."

With that explained it, both Gu Jiangli and the Emperor understood.

This method sounds a bit outrageous: a group of people hold ropes and cling to the straight city wall like sheets of paper, yet remain undetected.

There is only one reason for this.

Gu Jiangli and the emperor exchanged a glance, both understanding what the other was thinking, and spoke in unison:

"The darkest place is under the lamp."
