Chapter 1187 Abnormal

"Okay! Daoist friend Lu, please come this way!"

Mu Yuanshan led the way, while Lu Xuan and Zhang Jingxian entered an area covered by a towering tree.

Only when you walk down can you truly feel the amazing appearance of the ten thousand year old spiritual tree.

The trunk diameter is unknown, and branches of different lengths spread out, piled up like a small mountain, and the surrounding area is filled with extremely rich and pure vitality.

But it doesn't look very good at the moment. There are countless gray spots of different sizes on the thick trunk, and the gray spots reveal a dead atmosphere.

"Daoist friend Lu, wait a moment."

Zhang Jingxian stopped, and Mu Yuanshan, who was in the front, took out several green formation flags and waved them casually. The formation flags merged silently into the restriction under the spiritual tree.

"In addition to the two Yuanying fellows guarding the cave, there are also powerful restrictions under each sacred tree, which ordinary Yuanying Zhenjun cannot break."

Lin Jiangyuan on the side transmitted a message to Lu Xuan.

After more than ten breaths, layers of green curtains appeared under the spiritual tree, and a light gate that could only allow one person to pass through appeared in front of everyone.

Everyone entered in a line.

After entering, Lu Xuan flew up and stopped in front of a gray spot about ten feet in diameter.

"Fellow Daoist Mu, when exactly did these gray spots appear?"

He asked softly to Mu Yuanshan who also flew up.

"The larger the area, the longer it appears. The largest one has been there for nearly two years."

Mu Yuanshan was clear about the changes on the ten thousand year spiritual tree, and pointed to the largest gray spot.

Lu Xuan nodded gently and observed the ten thousand year spiritual tree carefully.

"These ten thousand year spiritual trees in the Shenmu Cave Heaven are of infinite value to the Shenmu Sect. The branches, leaves, rhizomes, spiritual liquids, and spiritual flowers and fruits are all rare treasures and can be regarded as the foundation of the sect."

Zhang Jingxian slowly introduced to Lu Xuan.

"The whole body is full of treasures..."

"Over the years, I don't know how many treasures have been contributed to the Shenmu Sect. No wonder the entire sect is famous in the cultivation world for various high-level spiritual medicines and elixirs."

Lu Xuan sighed in his heart.

A layer of hazy light appeared in his eyes, and his consciousness carefully explored the gray spots and the surrounding spiritual tree trunks.

Although he did not use his special ability, after all, he had cultivated countless spiritual plants over the years and consulted many spiritual plant materials in the sect. He can be called a spiritual plant master.

"..."

"It still doesn't work."

He retracted his consciousness and looked solemn.

That's right, so many spiritual plant masters in the Shenmu Sect didn't see any problems. If he could find the root cause without using external plug-ins, it would be a bit disrespectful to the entire Shenmu Sect.

"Fellow Daoist Lu, have you found anything?"

Zhang Jingxian asked in a deep voice.

"These gray spots on the ten thousand year old spiritual trees are already completely dead, as if the vitality inside was directly plundered by something."

Lu Xuan pondered for a moment and said.

"Several spiritual plant masters in the sect also thought the same after checking."

"But we can't find out what kind of strange monster insect or strange evil spirit has sneaked into the Shenmu Cave Heaven. We turned it upside down and didn't find anything abnormal."

Zhang Jingxian sighed lightly.

"Or maybe there is something wrong with the ten thousand year spiritual tree itself."

"It's just that Lu needs to study it carefully and collect the normal and gray spotted trunks of the spiritual wood for experiments."

Lu Xuan said slowly.

As long as it is a spiritual plant, he can get detailed information after planting it, but the ten thousand year spiritual tree is so huge, and it has an unusual meaning for the Shenmu Sect. Unless it is absolutely necessary, he can't dig out the roots of the spiritual tree and plant it again.

"After pretending to test for a few days, go to the roots under the spiritual tree to take a look."

He thought secretly in his heart.

"Okay, everything depends on Brother Lu."

Zhang Jingxian nodded and agreed, and Mu Yuanshan and others naturally had no objection.

Since Lu Xuan was invited from the Sword Sect from afar, he naturally had to respect the method he proposed.

For many cultivators of Shenmu Sect, they could only try their best.

Lu Xuan took out a fifth-grade sword grass and dug out a piece of normal spiritual wood and a piece of abnormal spiritual wood covered with gray spots.

Several people returned to a quiet cave in the cave.

This is where Mu Yuanshan and his companions practiced. Occasionally, cultivators of Shenmu Sect would come to stay in the cave for a long time, and practice and replenish supplies here on weekdays.

Lu Xuan entered an elegant room and used various spells and treasures to conduct multiple tests on the two pieces of spiritual wood.

Unfortunately, the gray-spotted spiritual wood did not react at all. Even if half a drop of the pure and vital Hunyuan tree sap was dripped into it, it just lay quietly in front of Lu Xuan.

"In addition to the possibility that unknown monsters and evil spirits may invade the cave, or there may be problems with the ten thousand year spiritual wood itself, there may be other situations."

"Stealing."

Lu Xuan looked calm.

Of course, in front of the two Yuanying cultivators of Shenmu Sect guarding the cave, he couldn't say this guess, so as not to be misunderstood by Zhang Jingxian and others.

At the same time, he also believed that Shenmu Sect would also secretly conduct an internal investigation, so he had to bury this idea in his heart.

"Daoyou Lu, it's rare for us to get together, come out and have a few drinks together."

Lin Jiangyuan's gentle voice sounded outside the house.

"Okay."

Lu Xuan removed a restriction that he had casually set up and walked out of the room.

The five people sat together and tasted the spiritual fruits and spiritual wine produced in Shenmu Cave Heaven.

Compared with those cultivated and brewed by Lu Xuan, those spiritual fruits and spiritual wines were not much inferior, and each had its own flavor.

When the wine was drunk, the few people became more familiar with each other, and even Jiang Hengbai, who had begun to question Lu Xuan, became more relaxed, but was a little cold and didn't pay much attention to Lu Xuan.

As long as the other party does not affect him, Lu Xuan will naturally not mind.

"It's a pity that Junior Brother Mu has been guarding Shenmu Cave for hundreds of years. I didn't expect that such a big problem would arise in the final stage of practice, and it would be impossible to have a beginning and an end."

Zhang Jingxian toasted Mu Yuanshan and said with emotion.

"yes……"

Mu Yuanshan sighed.

"There is no hope for me to break through, and my life span is short. I originally thought that I would slowly hand over the responsibility of guarding the cave sky and taking care of the ten thousand-year spiritual trees to Junior Brother Jiang, but I didn't expect that such a sudden change would occur."

"Don't think about this. With Fellow Daoist Lu here, maybe we can successfully solve the spirit tree problem!"

Lin Jiangyuan saw that something was wrong with the atmosphere at the scene and said aloud.

"By the way, the spiritual brew brewed by fellow Taoist Lu is a must in the spiritual world. Why don't you take some out and try it?"

He changed the subject.

"That's exactly what I meant."

Lu Xuan smiled and took out several bottles of spiritual brew such as Huanzhen Sword Liquid and Xinyan Wine.

“I can’t say it’s unique, but it has some characteristics and the quality is pretty good.”

He said with a smile and poured a glass for each of Zhang Jingxian and the other four.

"It's really good."

"Especially this fifth-grade sword liquid, it is actually able to integrate the subtle sword energy into the spiritual brew. It is simply unbelievable!"

"It's a pity that none of us are swordsmen, so we wasted this high-level spiritual brew."

Several people praised him one after another.

The spiritual brews that Lu Xuan took out were of high grade, high quality and unique, and several people couldn't help but appreciate them carefully.

"Um?"

Lu Xuan subconsciously focused his attention on everyone, and a thought flashed through his mind.
