For each outer disciple's question, Lu Xuan answered them in detail one by one.

He has been cultivating spiritual plants with his heart for many years, and after entering the sect, he has made up all kinds of knowledge about spiritual plants, so he knows many types of spiritual plants well.

When faced with various problems, either go to the critical point or peel back the cocoon to solve the problem of spiritual planting at the root.

This made everyone present admire and have a clearer understanding of Lu Xuan's attainments in spiritual plants.

Half a day passed, Lu Xuan said goodbye to everyone, returned to the side hall, and recuperated for more than half an hour.

When he returned to the main hall again, Lu Xuan found that there were actually half more monks in the field than in the morning, and there were three monks in the early stage of foundation building, mixed in the group of outer disciples, looking at Lu Xuan on the stage with expectation.

"In the afternoon, I will mainly talk about various cases of spiritual plants with incurable diseases, if you have problems that are difficult to solve, you can bring them to the stage, and we will study and discuss them together."

Lu Xuan said in a deep voice.

"Brothers, then I'm welcome."

A young monk stood up and clenched his fists and stepped onto the stage.

"Please help me take a look."

His spiritual power surged, and a talisman shot out, and immediately, a wide water curtain appeared in front of everyone's eyes, and there was a clear image on the water curtain.

The talisman is a second-grade water mirror talisman, which can be rubbed down by selecting a target, and after being excited, it can maintain a water curtain with a clear image for a period of time.

In some places in the spiritual world, this kind of water mirror charm is extremely popular.

At this moment, the clear image on the water curtain is presented in front of everyone.

In a pool of black mud, there is a white and flawless lotus flower, and there is a faint black gas lingering on the lotus.

"This lotus is called Rotten Water Lotus, a second-grade spirit plant, because it is at a critical moment of growth, I am afraid that transplanting it will have a greater impact, so I use this water mirror talisman to rub it down."

"Recently, somehow, a faint black gas appeared on the branches and leaves of the rotten water lotus, and I couldn't find the source, so I finally dispersed it, and it appeared on the plant again after a day or two."

"I have a lot of use for this rotten water lotus, and I am really anxious to encounter this situation suddenly, and I ask Uncle Lu to help me take a look with all of you, thank you!"

The young monk said solemnly.

"Could it be a spirit plant mutation?"

"It doesn't look like it, the black gas is just on the outer layer of the rotten water lotus, it shouldn't be a change inside the plant."

"Is it possible that there is some kind of insect infestation?"

……

There was a lot of talking.

Lu Xuan thought for a moment and asked the young man.

"Did the nephew carry the black mud from the pool with him?"

"Yes, yes."

The young man hurriedly took out a small bottle from the storage bag and opened the mouth of the bottle, revealing most of the black mud inside.

From time to time, black bubbles burst on the surface of the black mud, and the moment the cork is opened, you can smell a strong smell of decay.

"Uncle Shi suspects that there may be something wrong with this black mud?"

Lu Xuan nodded lightly and took out a spirit firefly spirit seed from the storage bag.

He put the spirit seed into the black mud, and a blue light fell on it.

The Spirit Firefly Grass is just a non-grade spirit plant, the growth cycle is short, and the cultivation method is simple, under the effect of the Wood Cultivation Technique of the Lu Xuan Dacheng Realm, and mixed with a trace of green wood source qi, in less than a moment, a slender and tender green spirit firefly grass grows out of the black mud.

If you look closely, you can see that there is an extremely faint black gas lingering on the delicate leaves.

"This ...... What's going on? ”

The young monk exclaimed in surprise, and everyone in the audience also concentrated and calmed down, paying attention to Lu Xuan's movements.

"Master, nephew, this black mud should have been taken from someone else, right?"

Lu Xuan continued to give birth to the Spirit Firefly Grass and asked.

"That's true, this rotten water lotus needs to grow in the rotten spirit soil, so I took a lot of rotten mud from a secret realm, but I didn't expect it to harm this rotten water lotus."

The young monk muttered to himself, his expression a little incredulous.

"If what I expected, there is a wisp of filth hidden in this black mud, which can be dispelled with corresponding talismans or magic weapons."

As the grass grows taller and taller, the black gas on the leaves also increases.

Everyone who saw this scene already believed in Lu Xuan's judgment for eight or nine points.

"There are often all kinds of breaths in the growth environment of spiritual plants, among which aura is the most common.

In addition, there are special auras such as evil energy, yin energy, and evil energy, which are not easy to evaluate simply.

The same breath can not only promote the growth of some spirit plants, but also greatly harm most of the other spirit plants. ”

"Therefore, in the process of cultivating spiritual plants, it is necessary to identify the surrounding spiritual energy well and provide the spiritual plants with the best growth environment."

Lu Xuan concluded.

The young friars stepped down with great gratitude.

After that, several outer disciples came to the stage, either with spiritual plants, or directly asking questions, and Lu Xuan patiently solved them one by one.

"Uncle Lu, it's been two and a half years since I obtained this hydrangea spirit seed, but I haven't bred a spirit plant for so long, so I don't know what's wrong."

"If it can't be cultivated again, the vitality in the spirit seed will probably pass away and become a waste seed."

A handsome-looking young man stepped onto the stage, holding a dark purple spirit seed in his hand, with a somewhat eager expression.

Lu Xuan took the spirit seed and put it into the spirit soil, and soon got the question about the abnormality of the spirit seed.

"Senior nephew, this hydrangea spirit seed should come from the depths of the earth, right?"

"That's true, I got this spirit seed in an underground secret realm that is thousands of feet deep, and the inability to conceive it has anything to do with this?"

The handsome young man was thoughtful.

"Hydrangea spirit plants usually grow in normal light environments, and the spirit seeds you get, because they have lived deep underground for a long time, have undergone generations of changes, and have completely adapted to the underground environment, and they can't give birth to spirit plants when they are brought back to the normal environment."

"So, you only need to plant this hydrangea spirit in a cool and dim cave, and bury it in the spirit soil at a depth of about twice as much as usual."

Lu Xuan proposed a detailed solution, and after the beautiful young man went down with gratitude, he turned his head to look at everyone in the audience.

"This hydrangea spirit seed should be able to bring you some inspiration."

"Cultivating spiritual plants also needs to be taught according to their aptitude, and cannot be brought into fixed methods and processes."

"You can establish a more intimate relationship with the spirit plants, understand the needs of the spirit plants, and adjust the planting methods according to their needs, so that they can always maintain a good growth state."

He used this hydrangea spirit seed, which could not give birth to plants, as an example, and said to the outer disciples who were listening to the class.

"Uncle Lu, I have a three-grade green jade branch in my hand, and it has suddenly become extremely abnormal in the past two days, can Uncle Lu help me take a look?"

Suddenly, an indifferent voice came, and Lu Xuan followed the voice, and a Qi Cultivation Consummation Cultivator who looked a little gloomy was looking at this side.
