Experience has become a task, which makes many disciples feel fooled.

The dean did not disclose why he was looking for the black-tailed fox, but just told everyone to be careful and safe, with a group of several people.

The two disciples of the Soul Sect did not enter the valley. Among the four disciples of the Dan Sect, only Lin Feng and the other one acted with the disciples of the Wu Sect.

The Black River Valley at night is a bit gloomy and terrifying, and the screams of various beasts and ferocious birds are particularly harsh.

"Follow me and don't run around."

Lu Yu did not stay with most people, but took Lin Feng forward alone.

"Where are we going?"

Lin Feng was a little uneasy, and the unknown darkness always gave people a sense of fear.

"Have you heard the legend of the Black River Valley?"

Lin Feng hesitated and said, "I heard from them on the road that this place seems to be a burial place. Many people died during the war, and they were all buried here. It feels so scary."

Lu Yu said: "The Heihe Valley is located in the Lingquan Mountains, just in the seven cities in the west of Tianyue Kingdom, between Quancheng and Wucheng."

Lin Feng said in shock: "How do you know? Oh, I almost forgot that you were the young lord of Wucheng before."

Lu Yu glared at him and continued: "Legendary: A long time ago, there was a big battle between Quancheng and Wucheng, with the purpose of snatching a treasure."

Lin Feng said curiously: "What treasure?"

Lu Yu looked around and whispered: "My father told me back then that there was a master who was ambushed when he carried the treasures through the Lingquan Mountains. The soldiers from Quancheng and Wucheng were attacked. The number of soldiers in Quancheng and Wucheng was as many as tens of thousands, but the result was blood flowing into a river. The master died in battle, but the treasures he carried were unknown."

Lin Feng said in shock: "You mean that the battle was not against Quancheng and Wucheng, but the ambushing the master together, and the entire army was wiped out?"

Lu Yu said: "The outside world has always thought it was a battle between two major cities, and there were only a very small number of insiders. My father once analyzed that the treasure was probably in the Black River Valley, but he had never found his whereabouts."

Lin Feng frowned and said, "The dean asked us to find the black-tailed fox. Could it be that he went for the treasure?"

"Who knows?"

Lin Feng exclaimed: "Since we are here, why not look around for twenty days?"

Lu Yu said: "I am just thinking about it. Now let's leave everyone's sight first and set up a formation later. I want to search for every move around me."

"The formation? It's also my hands."

Lin Feng's eyes lit up and he was excited.

"Do you want to learn?"

"think!"

"Then let's go."

Under the night, there were a few pairs of eyes behind the two, staring coldly.

Lu Yu seemed to have some awareness, but he didn't say anything. He took Lin Feng over a mountain and disappeared into the darkness.

The owner of those pairs of eyes did not follow, because everyone was together, and it would be too eye-catching to act alone.

Lu Yu found the densest woods and began to set up a formation here.

Lin Feng looked excited and helped pick up stones, insert flags, and collect various array materials.

"In the mountains and forests, the maze formation is the simplest, because we are the Jingwu Soul and have many resources to use. But the formation we are going to set up tonight is not the maze formation, but the small Five Elements Formation, the key points of it..."

Lu Yu explained carefully, demonstrated himself, and completed the small Five Elements Formation with Lin Feng.

"Formation is very important for alchemy refining, because some elixirs cannot be refined with alchemy furnaces. They must be supplemented by heaven and earth and all things, so that involves formations."

Lin Feng exclaimed: "Why do you know everything? It's so awesome."

"Stop flattering, go to the tree to keep an eye on me and protect the Dharma."

Lin Feng smiled, jumped onto the branches, and paid close attention to the situation around him.

Lu Yu sat cross-legged in the small Five Elements Formation, circulating the two soul techniques of the Green Grass Liantian and the Thousand Woods Formation Forest. The little Grass Martial Soul automatically emerged, swaying on his head, very leisurely.

Lu Yu takes grass as his eyes and thousands of trees as his ears, and his perception extends in all directions. Combined with the small five elements array, the search range can be greatly improved.

There are many birds, beasts, insects and snakes in the mountains and forests.

Lu Yu's grass eyes and thousands of trees ears are like a thousand miles of eyes and ears. As long as the area covered by grass and trees can be seen clearly.

One, three, five miles, Lu Yu's perception is constantly extending, and the grass martial soul above his head is shaking faster and faster, constantly absorbing the spiritual energy of the world in the forest in the night sky.

After a moment, Lu Yu's perception extended ten miles away, and a cold breath attracted Lu Yu's attention.

It was in the direction of the Black River Valley, and the cold and evil inexplicable power was invisible and colorless, revealing strangeness.

As soon as Lu Yu's perception approached, he felt like he fell into an ice cave, and even his heart was cold.

"This is……"

Lu Yu was shocked, opened his eyes and stood up, looking into the heart of the Black River Valley.

The night breeze is blowing, the birds are singing crisply, and the empty mountains are quiet. Who is calling you?

Above Lu Yu's head, the grass martial soul emitted a faint green light, and the Wanfa Pond on the third leaf flashed and disappeared, as if it had sensed some breath.

"Come again."

Lu Yu sat down, this time he was searching in a direction, focusing on the situation in the heart of the Black River Valley.

The perception quickly crossed the ten-mile boundary, and there was a river there. The water was turbid, like a black river, with a rotten atmosphere.

Lu Yu's perception went up the river, with lush grass and trees on both sides, piles of corpses and bones on the ground, and various poisonous insects and snakes appeared from time to time.

"That's where blood flows into a river."

Lu Yu searched carefully and found that the spread of his perception was slowing down, as if he was rejected by some evil force.

"This place is indeed weird."

Above Lu Yu's head, on the grass martial soul, the soul power line was swaying and swaying. The Wanfa Pool clearly appeared, prompting Lu Yu's perception to double and continue moving forward.

The Black River Valley is very large, but the area with a mountain of corpses was only a few miles away.

That area was covered by invisible evil forces, which felt like a ghost, and a bit similar to a curse.

After all, there was blood flowing like a mountain, and there was a strong resentment.

If the perception of ordinary people is close to it, it will be affected.

Lu Yu is the Soul Heaven Master. The soul power line and the Wanfa Pool of Xiaocao Wuhun are extraordinary, helping him overcome some difficulties.

After searching for half a day, a bone bead suddenly appeared in the Wanfa Pool, which was embedded inside a thigh bone and could not be seen from the outside.

This bone bead has no fluctuations, and its perception cannot be detected, and it is not known how the Wanfa Pool was discovered.

"Can it be that thing?"

Lu Yu was a little excited and wanted to look for him immediately, but it was strange that Wanfachi actually opposed his idea.

"It's not suitable to get close to you at night?"

Lu Yu could not think of a more reasonable explanation. With his extensive knowledge in his previous life, he could vaguely imagine that there was something strange about the Black River Valley, and the yin energy was too strong at night. His current realm was not enough, and he was a quiet martial soul, and his nature was yin, which was easy to attract bad luck.

The sun shines brightly during the day and the yang energy is strong, making it more suitable to go to those gloomy and weird places.
