Bai Bing, who ran back to the house, saw Xu Wei and Dongfang Bai coming towards him before he could ask questions.

"Xiaoice, Master and Elder Taishang have something to deal with, you stay here, don't run around." Dongfang Bai rubbed Bai Bing's head and instructed.

"Hmm!"

Bai Bing nodded, standing at the door prettyly, his crystal flickering gaze on Xu Wei and Dongfang Bai.

After hesitating for a while, her pretty face turned red, and she couldn't say what she thought in front of Dongfang Bai.

After all, it's too shameful to think like that, and if you want to say it, you have to tell the big brother secretly.

Xu Wei and Dongfang Bai left the bamboo forest courtyard together and went to the Zongmen Spirit Grass Planting Base.

Walking on the road, Xu Wei opened his mouth and asked, "Tell me, when did you find that the spirit grass began to wither?"

"Returning to Elder Taishang, according to the disciple who took care of the spirit grass, the large-scale withering of the spirit grass suddenly appeared yesterday, and there was no sign of it before. Dongfang Bai said beside him.

"So you've been investigating for so long, what are the results of the investigation?"

Xu Wei felt helpless about this, and he needed to help with such a trivial matter.

But he's also really bored, and he should find something interesting to do, or he'll just have to hang out outside.

Thinking about it this way, the broken bead of the black dragon has to find a time to return it to the dragon clan.

That's right, the dragon ball, which is regarded as a heavy treasure by the black dragon and has to be delivered to the dragon clan when he is dying, is a tattered in Xu Wei's eyes.

Dongfang Bai said ashamedly: "This ......"

"Returning to Elder Taishang, we have checked the soil of the Spirit Grass, the degree of Spiritual Qi in the Spirit Grass Garden, and the quality of the Spirit Grass, and we have found no problems, and there is no problem in the operation of the disciples who take care of the Spirit Grass, and they are completely in accordance with the Spirit Grass operation process. ”

"Well, in this way, the reason why the spirit grass is withering is because of other reasons. ”

After Dongfang Bai said this, Xu Wei was really interested.

Soon, the two of them came to the spirit grass garden, and they were greeted by bursts of spirit grass fragrance, which was very pleasant.

"Are you sure this is a spirit grass garden, not a weed garden?"

Looking around, the garden is basically a first-level spirit grass, at most it can refine some first-level elixirs, and the second-level spirit grass is very rare, which is why Xu Wei can't ask like this, just because these spirit grasses are really too rubbish.

However, it is also understandable that the tenth-level spirit grass is garbage in Xu Wei's eyes, not to mention the current situation of the Sun Moon Divine Sect.

Except for him, the Supreme Elder, the overall strength of the Sun Moon Divine Sect was not at all in the Xuanhuang Realm.

"Ahem......"

Dongfang Bai couldn't help coughing, and glanced at Xu Wei charmingly.

Knowing that Elder Taishang is a cow fork, we are not as bullish as you, I am really sorry.

"Elder Taishang, you're finally here"

The second elder Tao Niang saw Xu Wei from afar, stepped forward quickly, and took a group of disciples from the Spirit Grass Garden to salute Xu Wei, and said, "The old body begs the Supreme Elder to save these spirit grasses!"

As the person in charge of the Spirit Grass Garden, Tao Niang is undoubtedly the most concerned about this Spirit Grass Wilting incident.

"Get up, take me to see the withered spirit grass!" Xu Wei beckoned and said straight to the point.

"Elder Taishang, please come here!"

Under the leadership of Tao Niang, everyone bypassed a courtyard and came to the side.

Here, you can see a large spiritual field.

The spiritual energy contained in this spiritual field is much higher than that of the spiritual field in front of the courtyard, and the soil is much darker.

In the spiritual field, all the half-grown spiritual grass has withered, the leaves are black and yellow, and they are listlessly pulling, and when they are pulled out, the root system has festered.

The remaining half-adult spirit grass is very gratifying, delicate and green, exuding bursts of fragrance.

What's even more strange is that the withered spirit grass is scattered and distributed, and there is no pattern at all.

"Elder Taishang, you see, all the grass planted in this spiritual field is blue green grass, the cultivation method is the same, and the planting conditions are also the same, but for some reason, nearly half of the blue green grass will wither?" Tao Niang said bitterly.

"Did you cultivate these blue green grasses yourself?" asked Xu Wei.

Tao Niang was stunned, her beautiful eyes were shining, she looked at Xu Wei in surprise, nodded and said, "Elder Taishang, you are really amazing, you can see at a glance that these blue green grasses are cultivated by us personally." ”

Xu Wei smiled indifferently.

Although he had never planted a low-level spirit grass like Lanlucao, as long as he took a look at Lanlucao, no one could match his understanding of Lanlucao.

Therefore, when he first came to the front of the Blue Green Grass Spirit Field, he knew the reason why the Spirit Grass withered.

At the same time, there was a hint of loss in my heart.

It wasn't a man-made crime, so he had a little expectation that he was ready to play the detective again.

When playing the detective, in order not to bully people, Xu Wei will really make himself a mortal.

"Indeed, these spiritual grasses are cultivated by us by collecting seeds. In previous years, the blue grass was basically harvested from the wild or purchased from the auction house. Tao Niang said.

"Then how much do you know about Lan Lucao?" asked Xu Wei.

"Blue green grass is a second-level spiritual grass with a sweet taste and a neutral temperament. It can be used directly, and has the effects of detoxification, pain relief, and spasmodic. At the same time, it is also an indispensable intermediate spirit grass for many pills, which can reconcile hundreds of medicines and improve the success rate of the formation of pills. It can also be used as a main medicine to refine licorice, which has an obvious effect on detoxification and alleviation of internal injuries. Tao Niang said.

"What about the planting conditions?" Xu Wei continued.

"The blue green grass likes the sun and is slightly shade-tolerant, so it is a positive spirit grass. The requirements for soil are not strict, but I like to be moist, so I specially explained to the following disciples to extend the light time, and replenish water for the blue green grass five times a day, and the amount of water replenished each time is also the most appropriate. Tao Niang said.

"No?" Xu Wei looked back at Tao Niang.

Tao Niang frowned and pondered, and after thinking for a moment, she shook her head.

Xu Wei smiled slightly and led everyone out of the Spirit Grass Garden.

Tao Niang, who was following him, finally couldn't help it, and asked: "May I ask Elder Taishang, what is the reason for the withering of the blue green grass? I don't know the reason, my heart has always been hanging, for fear that the remaining blue green grass will also suddenly wither." ”

"Rest assured, the remaining blue grass will not wither anymore. Xu Wei said.

Tao Niang was stunned, and hurriedly asked, "I don't know why Elder Taishang said this, do you already know the reason for the withering of the blue green grass?"

Xu Wei said as he walked: "Although the level of the blue green grass is not high, it is a very magical spirit grass, which is divided into yin and yang. In the wild, both the negative and the positive are separate, and only during the breeding season will the two intersect. Any idea why?"

Peach Niang shook her head.

She also knew that the spirit grass was divided into yin and yang, but most of the spirit grass was the existence of yin and yang, and the spirit grass that was divided into yin and yang was indeed uncommon.

"That's because, the negative blue and green grass are all tigresses!" Xu Wei laughed, waved his hand, and slowly walked away with Dongfang Bai.

"Ahh ”

Tao Niang, who was stunned in place, suddenly woke up, her eyes were stunned, she figured out the key, she couldn't help but be overjoyed, and fortunately returned to the Lingcao Garden.

And the group of disciples led by Lin Chong were still standing in place with a confused expression, looking at the excited master for a while, and Xu Wei who was walking away slowly.

What is the situation, ask for an explanation?
