After Gatekeeper No. 7 came out, the road leading to the lower level became fast and shaky. Several passages were on slopes, and people had to slide down half-lying down.

There are also many places where you need to use climbing tools.

The forward speed was extremely slow, but the altitude dropped quite quickly.

It was pitch dark in the passage, and headlamps and flashlights could only cover a very small area. The passage turned around several times, and I thought it was the end. Only when I arrived did I realize there was another cave.

After descending to this altitude, the rock formations were relatively moist, and mineral veins had appeared. Most of them were worthless miscellaneous mineral veins. They only dug out channels and used wood and steel frames to support and maintain them, but they did not over-exploit.

About 5 hours further down, the Black Abyss enters an extremely open rock interlayer area.

The rocks here are clustered in flakes, with large gaps between the flakes. Toward the area where he was at the moment, the interlayer gaps could accommodate an adult walking half-crouched.

Many years ago, when the Hei people discovered and excavated the special rock formations here, they had already released and diluted the gas contained therein. At a vertical height of more than 10,000 meters underground, experienced practitioners will not feel chest tightness or shortness of breath, nor will they suffer from lack of oxygen.

coma.

Here, traces of human life and abandoned equipment are scattered everywhere, and some people even hide garbage in the crevices of the rocks.

Anyone who goes down to the ghost stream for experience will be warned that the sanitation and ecological balance in the ghost stream need to be maintained. Garbage must be packed in bags and placed at the gate guard camp or at a temporary resting place on the way. Every once in a while, the clan will send someone to deliver supplies.

Take away the garbage generated by human activities.

Quality is a thing that varies everywhere. Some people strictly abide by it, while others don't take it seriously.

The man was sitting in the dark without turning on the lights. He had to save power before arriving at his destination. There was a flat boulder under him, which was unexpectedly warm to the touch.

Heiyuan was greatly puzzled. He touched the surrounding stone surfaces and found a difference in temperature.

Driven by curiosity, without taking a break, he began to test the temperature of the rock.

The cracks in this layer of rock were not completely parallel, but were closed at one end and open at the other. The deeper he explored, the higher the temperature, but the narrower the cracks. In the end, he could only cling to the stone surface and reach out to touch it.

...There is something strange... Hei Yuan thought to himself.

In order to get the most accurate temperature, he took off the watch and placed it in different positions.

The difference between high and low temperatures is about 5 degrees, which is very noticeable in the body.

On a stone surface less than 10 square meters, there is a temperature difference of 5 degrees, which is an abnormal situation.

The man didn't know much about the situation in the ghost stream, so he had to suppress his doubts for the time being, rest for a while and continue on his way.

In the next few hours, the journey became much smoother and more complicated. He had to cross back and forth between the gaps in the rocks to find a way to the lower level.

Gatekeeper No. 8 is under this rock formation. The space here is larger, as if it had been hollowed out by large equipment.

Like an egg lying between two thick layers of rock.

When Hei Yuan arrived at the camp, his eyes were all attracted by the leaders of the three two-story ghost vines. Guard No. 8 had no time to pay attention to the visitor. He kept his eyes fixed on the barrier and tried hard to maintain it.

of completeness.

The space here is extremely wide, which is very suitable for the growth of otherworldly plants such as ghost vines. There are also mechanisms on the space rock walls that can emit light. Black Abyss finally does not need to use electronic equipment for lighting.

Hei Yuan's arrival surprised No. 8. He was a master at controlling his emotions. There was only a trace of doubt on his face, but it disappeared immediately.

"You are here to practice at this time. You are not very good at picking the time. What is it called? Which doll is it from?"

"Black Abyss."

When the young man announced his name, the guards who were trying to maintain the barrier were shaken, and this oversight directly led to serious consequences.

A leader vine of the ghost spirit vine struck the inner wall of the barrier, creating a crack.

No. 8's face was sweating profusely, and his hair and beard stuck tightly to his skin, as if he had just been fished out of the water.

Black Abyss predicts that if such a mistake happens again, the barrier will be broken.

The guard waved his hands faster and weaved them tightly on the barrier. After ten breaths, he was able to stop the barrier from breaking.

At this moment, No. 8 has already run out of gas and energy. The spiritual energy in his body is exhausted and he can no longer maintain it for much longer.

Just like No. 7 eating instant noodles, No. 8's despair at this time is greater than fear, and there is nothing else to think about except desperately maintaining the barrier.

"The token leading to the next level is in the camp tent. You can find it yourself." He paused and asked with difficulty the suspicion in his heart. "If you can come down safely, tell me what happened to the upper barrier? Is the Ghost Vine rioting?

Already?"

Heiyuan didn't say anything. These guards had special status. They all came from the torture hall to exchange their sentences. They were more or less responsible for the lives of several innocent people. He would not be stupid enough to tell the truth at the first meeting.

"Do you know me?" Heiyuan did not change places and remained where he was when he first came.

"Hahaha, let's get to know each other." The man tried his best to suppress his emotions and prevent the leader of the Ghost Vine from succeeding.

"You are Hei Huai's son!"

Perhaps sensing the resistance and hostility in young people's hearts, No. 8 did not talk nonsense and told the truth directly.

"I am your father's cellmate. When he came to the execution hall 25 years ago, he lived next door to me."

Heiyuan was stunned, and with ecstasy in his heart, he asked in a trembling voice: "What is the number of your cell?"

"No. 143, District 12, Xuanbu. Your father lives in No. 144."

"No wonder you came to Gui Stream to practice at this time. I think you have lived in the outside world since you were a child and have never been back to the clan. You don't know the rules of Gui Stream. Alas..."

Heiyuan did not expect that he would meet his father's cellmate here. He had been to his father's cell during the written examination in the criminal hall, and also noticed the situation in the next few rooms. There was almost no one in the cell in District 12. Except for 122

There is a prisoner in the room who is parasitized by insect pupae.

He clearly remembered the names of the inmates in the rooms next to his father's cell No. 144.

In cell No. 143, there lived a man named Huang Ruijun.

In the execution hall, unless the prisoner is released from prison or dies, the sign outside the cell will not be changed.

Huang Ruijun's brand has not been changed, but there is no one in the cell. Heiyuan couldn't figure it out before, but now he finally knows the reason.

However, the next moment, the young man seemed to think of something, and his body could not stop shaking.

...The sign of cell 144 has not been changed, and the people in the room have not died? Then where did he go? Is he also guarding a certain barrier under the ghost stream? My trip to the ghost stream is to see my father

?...

Guard No. 8 seemed to understand what the young man was thinking, and sighed: "Your father left not long after he moved in. I watched with my own eyes as the guards of the execution hall carried his body out."

In just a few seconds, Heiyuan experienced what it was like to go from heaven to hell.

"He...how did he die?" The word "death" was extremely heavy, and Heiyuan was reluctant to mention it, let alone hear the word "suicide" from the other person's mouth.

Guard No. 8's face showed confusion and confusion that Heiyuan could not understand.

"I don't know. I live next door to him and I don't know what happened."

"What's going on?" The young man finally left his previous position and moved closer to the barrier.

"Don't get too close. The ghost vine is going berserk. Be careful of being accidentally injured." No. 8 reminded me kindly.

Then he began to talk about the strange events that happened in the cell next to him.

...

25 years ago, a few days after the catastrophe in the secret realm of the clan tomb, Hei Huai was imprisoned in the execution hall as a traitor by the elders and moved to cell No. 144 in the Xuanbu District 12.

Six months before he came, Huang Ruijun was imprisoned in Room 143 for killing innocent people indiscriminately.

Huang Ruijun told Heiyuan that Heihuai was definitely a tough guy, just like him, he was stubborn and stubborn.

According to Huang Ruijun's recollection, in the month after Heihuaiguan came in, there were more than a dozen waves of interrogators, and they came from various families in the Ninth Prison.

At that time, he still didn't know why Hei Huai, the rising star and the chosen son of the Black clan, became a prisoner. It was only after repeated interrogations that he understood what this person had committed.

"After your father was imprisoned, no matter what the identity of the person who came to interrogate him or which family he came from in the Ninth Prison, he remained silent and refused to answer. Alas..." Thinking of those days, No. 8 still felt his spine go up.

His bones were cold, and he did not tell the young people that they had tried every means to force Heiyuan to tell him what happened in the secret realm of the clan tomb.

The tough-minded man never let go.

"At first I thought your father had made a big mistake, but as time went on, I became more and more suspicious."

"Your father is a very quiet man. In the past, I only saw his name in the top ten on major forum lists. I never thought that one day I would be a prison cellmate with him."

The memories were very long, and Heiyuan could see that Huang Ruijun truly admired his father, and his hostility towards him unknowingly weakened a bit, and he moved closer to him.

"What happened to my father before he died?" Heiyuan asked in a deep voice. His emotions were tumbling in his chest. Of course he knew what his father saw in the secret realm of the clan tomb. Why did the families of the deceased disciples and descendants come to interrogate him?

he.

But he couldn't tell others, it was an agreement between him and the clan leader.

"Speaking of which, there is indeed something strange about it."

"I remember clearly that about a week before your father died, he became a little weird. He would walk back and forth in the cell during the day, mumbling something, like talking to himself or talking to someone.

chat."

"It's not quiet at night either. It often makes strange noises. I couldn't hear them clearly from next door. The sounds were very dull, as if they were made by being stuffed in a can."

"What does it sound like?" Heiyuan asked anxiously.

When the young man asked this question, Huang Ruijun smiled awkwardly and said, "At first, I thought your father was trying to escape from prison and was digging a tunnel."

"Later I found out that it was not the case. The reason given by the execution hall was that your father was in a daze because he had caused a big disaster and could not forgive himself."
