After an unknown period of time, a gust of wind blew through the dark and gloomy passage, causing the light of the oil lamp to flicker!
Then, he put down the oil lamp and touched the wall on the side. With a clang, a small hole appeared in the wall.
Under the illumination of the oil lamp, a mask and a sword appeared in the small cave.
After putting on the mask, he took out the sword and continued walking forward.
In a short while, he had already walked out of the entrance of the passage.
At this moment, he was already in a small courtyard on the outskirts of the capital.
It was obvious that this was the secret passage of the Imperial Grandprince Residence, or rather, it was a secret passage hidden in the heart of His Highness Yuwen Xuhong since he was young.
As soon as he appeared, three black shadows flew towards him and knelt before him. They shouted in a cold and emotionless voice," Greetings, Hall Master!"
