With the silver taels he had saved since leaving the palace, plus 2,200 taels of two hundred-year-old ginsengs, Fang Ling finally gathered three thousand taels of snowflake silver, and all this was just to meet the female assassin.

After handing over the three thousand taels of silver to Dong Canghai and letting him clean up the various checkpoints of the prison, in the dead of night and day, Fang Ling and Dong Canghai finally went to Dongshan, where the prison was located.

The Heavenly Prison, which means the prison of the Son of Heaven, is ordered to detain important criminals in the name of the Son of Heaven, many of whom are imperial ministers and ministers, and the guards are not inferior to the inner palace.

The guards of the inner palace are generally the elite soldiers and strong generals in the Royal Forest Army, and once there is a disturbance, they can get the support of the outer palace garrison, but it is not only the guards who are firmly entrenched.

Dongshan is one of the five mountains of the Imperial Palace, and the entrance to the prison is at its feet. The prison is to dig up the Dongshan mountain, the inside goes straight down hundreds of meters, and then the surrounding is built with several meters thick boulders, pouring and solidifying, which can be described as an iron wall.

It's like an iron bucket, with three layers inside and three layers outside, and the place is small, so it's more difficult to mix it up than to climb to the sky, let alone want to get out after entering.

The guards are the elite soldiers drawn by the Criminal Department, and the only key that can get through here is a large pile of silver.

Under the moonlight, the entrance of the heavenly prison at the foot of the East Mountain is like a monster with a bloody mouth open, which makes people feel suffocated, and a building is built along the mountain on both sides of the entrance, although there are no people in sight, but Fang Ling clearly feels that countless pairs of eyes are staring at him.

Only then did Fang Ling understand, no wonder he needed three thousand taels of silver to make a point, so many pairs of eyes were open, even if it was five taels, it would cost several hundred taels, not to mention, there were nine layers in this prison.

Leading the way for Fang Ling and the others was a middle-aged man named Ma Chaoge. This person is the deputy general in charge of the power of the prison, although he is only a deputy general, but because he is exquisite, has various connections, and can eat and drink spicy food with him, so he naturally has a lot of henchmen.

With such a network, it is possible to avoid the main general and bring people in. Dong Canghai naturally did not reveal Fang Ling's identity, and Ma Chaoge naturally did not ask, how many secrets are hidden in and outside this palace, and it is a good thing to ask less.

Under the leadership of Ma Chaoge, the two walked down the prison layer by layer along the passage.

The nine-layer prison, the more you go down, the more important the prisoners are held, and the guards are naturally strict, and each layer has a guard guard on the road that must be passed, monitoring every move inside.

The vision in the prison was very dim, only a few torches were inserted in the spiral staircase, the light was bright and dim, and the yin qi came from the ground, which looked eerie and terrifying, and from time to time there was the sound of ghosts crying and howling.

Rao is Fang Ling thinks he is bold, and sometimes he is frightened by this voice.

I don't know how long I walked, but the spiral staircase finally came to an end, and there was only an arc-shaped passage ahead, which was the ninth floor.

The cold air under the ground was like an ice cellar, and compared to the sound of the ghost crying on the previous floors, there was no sound at all, but it was even more terrifying.
