Hei Yuan did not help Zhang Chengliang suppress the growth riot of the ghost vine.

Firstly, Zhang Chengliang was very powerful and a mid-level high-level cultivator was enough to cope with the situation at hand. Secondly, if this person wanted to follow him, he had to come up with something. Finally, Heiyuan quickly arrived at the center of the planting area. He had a clear understanding that this

A riot started because of him and will end because of him.

The center of the planting area coincided with the destination of his trip, so it was not a big deal to solve the immediate trouble easily.

It would be strange if the guards and the disciples of the medicine hall who were in trouble knew what was going on in Heiyuan's mind.

...

According to the predictions of Guard No. 10 Zhang Chengliang and Heiyuan's own assessment, the road ahead was a bit dangerous, but it was not as complex and changeable as the terrain in the Guijian Mountain cave above his head, and a lot of heavy rock climbing equipment seemed redundant.

After taking a short rest, Heiyuan abandoned some of his heavy equipment and set out on the road lightly.

His speed was not slow before, but it was faster this time.

The passage to the center is still complicated and needs to be repeated repeatedly. Sometimes it will circle back and forth several times before a new passage appears.

Zhang Chengliang also mentioned on this point that the people who come down for inspection have special footwork. Characters like the patriarch have already learned to teleport over long distances. As long as they have been to a certain place and marked it, they can reach it in a few breaths.

Only experienced practitioners like Hei Yuan who break in for the first time will be trapped in the complicated passages for a day.

About five hours later, Heiyuan, holding the special token given by the clan leader, finally saw the research room in the middle of the planting area.

It's not so much a research laboratory as it is a small camp built with stones and a barbaric style tribe.

The tribe is covered with a barrier, and from the perspective of the black abyss, there is no movement at all.

The leaders of dozens of 2 or 3-story ghost vines were frantically beating the barrier with their vines, trying to break them and break in. Maybe the human flesh and blood inside was too sweet, or maybe it was the guys from these medicine halls who usually

The methods used to test them were too harsh.

Anyway, as No. 10 feared, the Medicine Hall disciples are in trouble.

Heiyuan kept approaching with the token in hand, and the special wave produced in the token was received by the leader of the Ghost Vine. The frantic slapping movements stopped, and those guys stopped and tilted their heads to look at the intruding humans.

The tallest guy among the leaders seemed to be the leader of this group of leaders. He stretched out a cane and the ghostly human face carefully moved in front of Hei Yuan, looking very cautious.

Heiyuan put the token in front of him and said coldly: "What are you doing, why don't you retreat?"

The ghost was a little afraid of the token and struggled for a few seconds before nodding and retreating.

Seeing that the leaders gave in, the leaders obediently put away their violent canes and cleared the way to the research room.

After retreating, Heiyuan found a dozen new ghost vines next to the dense vines and roots of the ghost vine leader group. They were less than half a person tall, and the vines were still very young and not dull in color.

He didn't have the ability to show ghosts, so he was blocked by his parents like a kid.

After the ghost vines stopped attacking, the area around the outer boundary of the laboratory returned to calm. These little guys, who were just a few days old, tilted their thick, yet-to-be-grown heads and looked at humans curiously.

Some brave ones even use the vines to slowly move closer to observe and transform into melon-eating plants.

The plants grew wise, not knowing whether to be happy or sad. Hei Yuan moved forward silently, carefully guarding against the tall guys behind him.

When I walked to the edge of the barrier, I could clearly see what was going on inside.

The disciples wearing the standard uniforms of the medicine hall were lying on the ground. Only 2 or 3 were still in a meditative posture, pinching the sword in their hands, barely supporting the barrier.

The doors of several houses were wide open, revealing some details inside. With just a glance, Heiyuan found that most of the people in the houses had also fainted and fell to the ground.

To solve the immediate problem, he must enter the barrier.

...I wonder if the token given by the patriarch can be used to enter?...

He tried to call out to the two medicine hall disciples who were maintaining the formation, but received no response.

Taking a few deep breaths, Heiyuan stepped towards the barrier.

The barrier of this central research room is no better than any other guarding barrier. It is solid and thick, like a thick layer of membrane that covers the entire research room. Black Abyss can enter, but it is quite difficult.

It was the first time he felt such a viscous material outside the abyss space.

They tightly wrapped Hei Yuan's whole body, leaving no gaps.

The man's entire body was neither inside nor penetrated by the substance.

His entire face was pulled back by something, deforming and looking hideous.

Fortunately, although the action was difficult, it was still passed.

The moment they penetrated the barrier, the two Medicine Hall disciples maintaining the formation seemed to feel something, and their eyes were heavy and slightly raised.

The moment they saw it, they all fainted.

The barrier disappeared at a speed visible to the naked eye.

Fortunately, Heiyuan held the token given by the clan leader. When the clan leader came in person and the barrier disappeared, the restless hearts of the ghost spirit vine leaders were stirred up again, and they all turned their heads to look here.

How could Heiyuan let them succeed? He held up his clan order openly and secretly unleashed his unparalleled spiritual power.

Before the Ghost Vine leaders had time to think about what happened, most of them fell to the ground and fainted.

When the spiritual system meets the spiritual system, the strong will crush the weak.

Without any hesitation, Heiyuan took the lead in rescuing the two medicine hall disciples who had just fallen unconscious.

They stay awake the longest and are easy to rescue.

Heiyuan also had two Ling Ling Pills in his backpack. Each person put one in his mouth. After more than ten breaths, the two of them woke up leisurely.

Their depleted Dantian was replenished, and the chaotic sea of ​​consciousness gradually stabilized.

After all, they were young and had high cultivation. Hei Yuan arrived just in time, and they quickly regained their sanity.

One of them, a slightly older man, about 40 years old, immediately checked the barrier formation after he woke up. He looked at the empty head and was about to yell something bad, but he saw the ghost spirit vine that was running wild and rampant just a moment ago.

The leaders huddled together like bald phoenixes on the ground and stayed as far away from the research room as possible.

At the second glance, he discovered that a strange young man was rescuing his fainted companions on the ground one by one.

He didn't have time to ask what happened and immediately joined the rescue team.

The central research laboratory in the Ghost Vine Planting Area maintains a daily staff of about 20 people, with 10 people resting in their respective residences, waiting for their shifts.

Since the outbreak of the Ghost Vine, all these people have mobilized, desperately burning spiritual energy to maintain the barrier, waiting for rescue. One after another, the spiritual energy has dried up and fell to the ground in a coma.

Rescue finally came.

Most of these people were not sufficiently cultivated and had only reached the low-level peak, so their recovery was quite slow. Fortunately, they were disciples of the medicine hall and they still had medicines in reserve. Each of them was given almost one pill, which was just enough for one round.

If it weren't for the two life-saving Spirit Fusion Pills on Hei Yuan's body, there would still be two left.

The disciples of the medicine hall who had regained their consciousness looked at the strange young man as if they were their savior.

In the end, it was the older man who spoke first.

"What do you call this little brother? We are disciples of the Medicine Hall and are responsible for the daily maintenance of Ghost Spirit Field. Some of us have not been there for 2 or 3 years. This little brother is a bit unfamiliar and we don't know him."

How can ordinary practitioners go deep here, not to mention that Heiyuan still holds a special token, so his identity is definitely not simple.

"My name is Kuronuma, a branch of the Black family. I am the teacher of these Medicine Hall disciples and the head of the research laboratory."

"Down in the dark abyss."

When Heiyuan announced his name, the man heard two gasps from behind him.

"It's him!"

"How could it be him!"

Hei Yuan had heard of Hei Yuan's name and was familiar with it. Before coming to Hei Clan, Boss Qu made a copy of the family tree and gave it to Hei Yuan, considering Hei Clan and Jiujian as the main figures of the third generation and the relationship between them.

This Black Marsh and his elder brother Hei Zhuo are both from the side line of the Black clan. In terms of importance, Black Marsh's line is closer to the main line, so he can hold important positions in the medicine hall and can come to the Guijian Underground Planting Area to become the person in charge.

The planting area under this ghost stream is definitely one of the core secrets of the Black Clan.

Such an important position must belong to an internal member of the Black Clan.

The names of the Nine Supervisors have their own characteristics. In the past five generations, the Hei people like to use single characters for their names, and the five elements are used as radicals among peers. People of the same generation as Heiyuan are all named with a single character next to the three points of water.

This Kuronuma is of the same generation as him.

Knowing the origin of Hei Yuan, the expression of Kuronuma, the head of the research laboratory, was stiff for a moment, but he soon let go and started talking freely with Hei Yuan.

Kuronuma briefly explained his purpose and showed his token. Kuronuma's smile became more relaxed.

"You and I are of the same generation, so don't be too unfamiliar. You call me Senior Brother, and I'll call you Junior Brother Yuan."

"Okay, Senior Brother Numa, what is this laboratory built to study? Why are so many ghost vines planted in the planting area? I have encountered many such magical plants along the way. If you can tell me something, I would be grateful."

The cold-faced young man was able to get the clan leader's token to penetrate this place, and he was from the Black Sophora clan, the main line of the Black clan, and he had the clan leader's trust. These secrets were not leaked to him.

Kuronuma brought the young man to the office, adjusted his breathing a little, and when his face was glowing and his hair changed, he sighed: "It's a long story."

"There is no need to hide these things from you, but before explaining, senior brother would like to ask you a few questions."

"Please say."

This Kuronuma is more than 40 years old, with white hair on his head and deep wrinkles on his forehead, probably caused by worrying day and night. His appearance is still good, his skin is dark and healthy, and his body is strong but not exaggerated.

His temperament is upright but not pedantic, but he is a bit stern. Generally speaking, he is an easy person to get along with.

"What's the name of the pill you fed me just now? I'm not afraid of your jokes. I call myself a disciple of the medicine hall, and I have never seen a pill with such amazing effectiveness."
