Xiao Lingyue calculated the distance while walking.

Since they entered the secret passage, they have already left the Jiang Mansion and are almost at the outskirts of Huaicheng.

"Is the exit hidden on the mountain in the suburbs of the city?" she guessed casually.

Zhan Beihan was too lazy to guess, "No matter where he was, he would know it when he arrived."

As soon as he finished speaking, the secret passage that had been moving forward suddenly turned around, and the faint sound of wind and air began to grow.

The two of them quickly moved forward, and in the next half hour, the inner environment of the secret passage became obviously complicated.

From time to time, turn will appear, and the width will become unstable. The narrowest place can only accommodate one person, but the widest place is like a small room, and there are also wooden support columns to prevent the soil layer above the head.

Collapse.

There are more and more chaotic traces on the ground, with ruts and footprints. It seems that many people have been active here.

"It's coming soon." Xiao Lingyue whispered, and the sound of the wind in the secret passage had become very obvious, whirring.

The candle in her hand could hardly hold back, and the flames were blown to the point of being blown away.

The more obvious the wind sounds, the closer they are to the exit.

"Start up and go out before the Jiang Mansion reports the message." Zhan Beihan said in a deep voice.

Xiao Lingyue simply blew out the candle.

The speed of the two people immediately increased, and they used their light skills to quickly travel. It seemed like two afterimages passed by in the darkness, and hundreds of meters were in the blink of an eye.

Soon, the end appeared.

A steep slope appeared before the two of them. The slope was covered with deep ruts, and several old long hemp ropes were scattered on the slope, and the other end disappeared into the darkness.

Xiao Lingyue stood under the slope, carefully picked up a hemp rope and gently pulled it. "The front is tied and fixed very tightly. It should be used to borrow force when the cart goes uphill."

Zhan Beihan nodded: "Go up and take a look."

The two of them walked up the slope and only walked a short distance of twenty or thirty meters, so they had to stop.

Because there is no way.

A tall and heavy iron door fell at the end of the slope, blocking the road tightly.

The wind they felt in the secret passage before was blowing in through the cracks and breathable holes of the iron door. The more they reached in front of the door, the more rapid the wind became.

The iron door was bare, not even a door knocker, and there were cold and thick stone walls on both sides, as if they were dead end.

Xiao Lingyue tried to push forward and frowned and said, "No, the door is too heavy, and it may not be pushed open by human power. It should be controlled by the organs."

As the only exit from the secret passage, it is an important passage for Jiangfu to smuggle iron ore. For convenience, the arrangement of the exit mechanism will not be too complicated. Otherwise, it will take a long time to open the door. Isn’t that delay?

The question is, where will the agency hide?

Xiao Lingyue and Zhan Beihan looked at each other and looked for each other tacitly.

One is responsible for the left and the other is responsible for the right, knocking on the iron door and the stone walls on both sides, looking for empty places.

This time, it was Xiao Lingyue's turn to be good luck. She pounded the stone wall on the right a few times, and soon a stone made a "dongdong" sound.

Xiao Lingyue's eyes lit up, she groped along the edge of the empty stone, found the groove and broke it hard. The wooden board disguised as an ordinary stone opened like a cabinet door, revealing a rectangular hole inside.
