Here, Mo Hanqing and Mr. Gu followed a group of officials to an extremely remote small courtyard to the west of the Prince's Mansion.
Only one lamp was lit in the main building in the courtyard, emitting a dim light in the silent night.
Not long after the officials entered the main building, the lights came on one after another.
After a moment, all the lights went out instantly, and the entire courtyard fell into darkness again.
Mr. Gu turned his head and explained in a low voice to Mo Hanqing: "Your Highness, there is a tunnel behind this small building. The prince and the officials went along this tunnel to another courtyard. That courtyard It is even more remote, surrounded by woods, and there are heavy troops guarding outside the woods."
"Yeah." Mo Hanqing responded lightly.
"Should we... follow him now, or wait a while?" Master Gu hesitated for a moment and asked Mo Hanqing.
"Wait a while." Mo Hanqing looked at the small building in front of him and said to Mr. Gu: "Let's go to the main building first to explore and see what's inside."
"Yes." Master Gu responded in a low voice, then followed him and sneaked into the small building secretly.
It was dark inside the building, and nothing could be seen without a light.
Mo Hanqing took out a luminous pearl from his sleeve robe, blocked part of its light with his sleeve, and looked around.
Master Gu followed him step by step, looking around.
This small building looks like a library, with rows of bookshelves inside, and each row of bookshelves is filled with books.
Mo Hanqing and Master Gu walked through the rows of bookshelves, but did not notice anything unusual.
"Your Highness, this seems to be a library." Mr. Gu lowered his voice and said to Mo Hanqing: "The previous spies also wandered around this building and found nothing unusual."
"Yes." Mo Hanqing nodded lightly, but when Master Gu didn't notice, he put his sleeves against the bookshelf and shouted in a low voice: "Black python, go."
A black shadow quickly emerged from his sleeves and disappeared in an instant.
"Your Highness?" Lord Gu faintly heard his voice and couldn't help but raise his head and look towards him.
"Wait a moment." Mo Hanqing stood expressionless, her dark jade-like eyes staring straight at the dark figure wandering between the bookshelves.
Pythons' eyesight is not very good, but when they catch prey, they can rely on the temperature of the animal to identify its location.
Although the books in this library have no body temperature, once a certain book is taken by someone, that person's body temperature will remain on the book.
Before the residual heat disappears, the black python can rely on its own sensing system to find the touched book.
Sure enough, in just a moment, a fully bound book was thrown down, and the black python had quickly re-entered Mo Hanqing's sleeves.
Mo Hanqing lowered his eyes slightly and looked at the book lying on the ground. After a moment of silence, he suddenly spoke to Mr. Gu: "Mr. Gu."
"Ah?" Master Gu turned his head and looked at him respectfully.
"There is a book on the ground." Mo Hanqing raised his chin towards him, his eyes fixed on the book on the ground without moving.
Master Gu followed his line of sight and looked over, and sure enough, a book was lying there quietly.
