Only then did Ling Mu understand why the elixir between heaven and earth grew so slowly, and it would take at least a hundred years for the elixir to grow in nature before it could be effective.

Because of the existence of the Spirit Sucking Grass, whether it is the elixir that grows naturally or the elixir in the medicine gardens of the various sects, the growth will not become very slow.

Of course, compared with the wild elixir, the elixir in the medicine garden will grow slightly faster because someone takes care of the weeding.

However, since the medicine garden is planted in large quantities, and the place of the medicine garden is very limited, the heaven and earth aura that can be obtained by each elixir will be relatively small, and the actual growth rate will not be much faster than the elixir in the wild, and sometimes even slower.

However, Ling Mu thought that this Spirit Sucking Grass was completely different from the Iron Wood Fly, this Spirit Sucking Grass grew outside, and it couldn't move, as long as he sent some more people to keep patrolling the medicine garden.

"Elder Ning Yuan, then why don't you send more people over to weed, although there are many spirit sucking grasses, they can still be cleaned. Ling Mu looked around and found that the weeds in this medicine garden could still be completely removed.

Elder Ning Yuan smiled when he heard this, and said, "You are wrong, the Spirit Sucking Grass must not be pulled out completely, otherwise the consequences will be very serious." ”

"Why?" Ling Mu didn't understand what serious consequences could be if he pulled out all these spirit sucking grasses.

Ning Yuan stretched out his hand again and pulled out a spirit sucking grass and brought it to Ling Mu, "You look at the roots of the spirit sucking grass. ”

Ling Mu took a closer look and found that there were many dense dots on the roots of this Spirit Sucking Grass, and if the grains were not arranged together, they would almost not be visible to the naked eye.

"It's ...... Could this be the seed of the Spirit Sucking Grass?"

Ling Mu looked at these dense dots and thought of the eggs of the ironwood fly that he had seen in the Hundred Qi Fruit before.

"That's right, these are the seeds of the Spirit Sucking Grass, from the moment the Spirit Sucking Grass sprouts, its roots will continue to grow seeds, and this medicine garden has countless Spirit Sucking Grass seeds. Ning Yuan's tone was a little helpless, and he continued: "And this Spirit Sucking Grass is very strange, no matter how many seeds there are in the ground, there will only be a maximum of four Spirit Sucking Grasses growing around each elixir, and other seeds will lie dormant on the ground, if there is a Spirit Sucking Grass withering or being pulled out, the seeds below will quickly sprout and grow." ”

Ling Mu didn't expect these little weeds to have such a tacit behavior, "Then even if the seeds will continue to germinate, wouldn't it be good to reward them for pulling them out when they break through the soil, what serious impact can it have?"

"After listening to me, the aura that these sucking grasses suck in the process of stretching out is actually very small, but when the sucking grass sprouts and matures, it will absorb a lot of aura, so we will only get rid of those mature sucking grasses, and the growing sucking grass not only cannot be pulled out, but also must be protected. Saying this, Ning Yuan let out a long sigh.

After listening to this, Ling Mu could also understand Ning Yuan's helplessness, but he didn't understand why Elder Ning Yuan was talking to him about this, he couldn't just want to explain it to himself.

"Did Elder Ning Yuan tell me that I needed to do something?"

Ning Yuan smiled and said: "That day, I saw your sweeping skills in Nanshan City, and found that you can control even the tiny dust, I want you to try, can you suck up all these seeds buried in the ground." ”

"Suck up the seeds in the ground?" Ling Mu was stunned for a moment, then looked at the land and said, "I'll try it." ”

Ling Mu closed his eyes and started the Spirit Devouring Technique, but he couldn't find any traces of the Spirit Sucking Grass seeds, and the spiritual energy in these seeds was even less than the eggs of the Iron Wood Fly.

Ling Mu shook his head, "No, last time I swept the floor, I adsorbed indiscriminately, and I absorbed all the lighter things, but if I wanted to find out the seeds of the Spirit Sucking Grass one by one, I couldn't do it at all." ”

Ning Yuan also knew that he was a little strong, and he just had the attitude of giving it a try and asked Ling Mu to give it a try.

"It's okay, this kind of thing is almost impossible, it's the old man who thinks too much. ”

However, at this time, Ling Mu suddenly found that the aura he had just inhaled into his body with the Spirit Swallowing Technique actually had the aura of sucking spirit grass seeds.

Ling Mu was overjoyed in an instant, and said in his heart: "Although I can't absorb these seeds out of the soil, I can use the Spirit Devouring Technique to directly absorb all the spiritual energy in these Spirit Sucking Grass Seeds, so that these Spirit Sucking Grass seeds will not sprout." ”

Thinking of this, Elder Ning Yuan, who was beside Ling Mu, said, "Elder Ning Yuan, although I can't help but talk about sucking out these Spirit Sucking Grass seeds, I can kill them directly in the soil. ”

Ning Yuan, who was still disappointed, heard Ling Mu's words, pressed Ling Mu's shoulders with both hands, and said excitedly: "What you said Ling Mu is true, you can't deceive the old man!"

"How dare Ling Mu deceive the elders, if Elder Ning Yuan doesn't believe it, as long as Ling Mu is given a day, he can know the truth and falsehood. ”

As far as the strength in front of Ling Mu is concerned, it is still not a problem to get rid of the Spirit Sucking Grass Seeds in a small piece of land.

Ning Yuan really didn't believe it, these seeds were buried deep in the soil, and it was almost impossible to find them one by one and destroy them, "Okay, you can get this medicine garden as you want, but don't destroy my elixir, just come to me directly if you have anything." ”

"Elder Ning Yuan, you can rest assured, you will know if it will work when you come over tomorrow. "Ling Mu originally wanted to use this trick to help Wen Ze deal with the eggs, but he didn't expect that now he would help Elder Ning Yuan deal with the weeds first.

Ling Mu didn't say much, he sat down cross-legged, and once again started the Spirit Devouring Technique, but this time the target of Ling Mu's absorption was no longer the spiritual energy between heaven and earth, but the spiritual sucking grass seeds buried deep in the soil.

Soon, a trace of aura gathered over, although these aura were not many, and could even be described as thin, but Ling Mu was still very happy, because these aura came from the seeds of the spirit sucking grass.

Ling Mu's current power could absorb up to two meters underground, but that was enough, because the seeds of the grass that had been sucked would not be very deep underground. It is only one meter at most, and it cannot germinate at depth.

Soon, the land within a radius of one meter around Ling Mu had been absorbed by Ling Mu, and Ling Mu used the Spirit Swallowing Technique to absorb it five times, although there was no spiritual energy at the third time.

However, for the sake of safety, Ling Mu still used the Spirit Devouring Technique to absorb both sides before he dared to continue exploring around.

One fan, two meters, three meters, four meters, five meters. Ling Mu worked tirelessly to absorb the spiritual energy in the soil to absorb the spiritual grass, although the spiritual energy of these seeds could help Ling Mu's cultivation, but this kind of thing also consumed Ling Mu's physical strength very much, after absorbing the seeds within a radius of five meters, Ling Mu was also completely exhausted.
