After listening to Ning Yuan's words, Ling Mu was even more convinced that the elder in the Sword Valley must be guarding something, and there must be something in the Sword Valley Abyss, but Ling Mu was naturally not qualified to know these things.

However, Elder Ning Yuan is not running out of oil now, and his lifespan is still very long, so there is only one reason why he needs the Ice Demon Spring, and that is that he has been injured, and he has been injured very terrifyingly.

Although most injuries will heal on their own, if they are too serious, it will take a long, long time, and it will also delay their cultivation.

Just like a dream of Liangqiu, two thousand years ago, the dantian was broken, although it is constantly being repaired, but even after two thousand years, it is still not repaired.

The Ice Demon Spring contains the most primitive life force in this world, and no matter what kind of injury people have, they can be completely healed.

"Is Elder Ning Yuan seriously injured?" Ling Mu asked the doubts in his heart.

Ning Yuan sighed and looked at the Sword Valley in the distance, "Back then, Wen Ze and I wanted to explore the secrets of the depths of the Sword Valley, the depths of the Sword Valley, which is called the abyss. However, the Sword Valley Abyss has always been a place that the Ancient Sword Sect avoids talking about, and at that time, no one knew what was there, but they all sent elders to garrison in Sword Valley, but they never let anyone take the next step. At that time, Wen Ze and I were young and vigorous, and we were full of curiosity about the Sword Valley Abyss, so I agreed that when the two of us were stationed together in the Sword Valley again, the two of us broke the ban and went to the Sword Valley Abyss. ”

Only then did Ling Mu understand why Wen Ze and Ning Yuan had been demoted from elders to the management of orchards and medicine gardens.

"I can't talk to you about the following things in detail, you can't know yet, but I can tell you that Wen Ze and I were injured there, and we were almost incurable, although it was not fatal, but our strength declined from the Sage to the Heavenly Pole Mirror, and the two of us were punished for this, I was punished for guarding the medicine garden, and Wen Ze was punished for guarding the orchard, but this was also the best result for the two of us. We made an irreparable mistake. Even if Ning Yuan recalled the events of that year, he couldn't help but feel a little sad.

After all, it was the mistake he made at the beginning that would make it happen, so that the elder could not leave Sword Valley.

Ling Mu quietly walked in front of Elder Ning Yuan, and said quietly, "Elder Ning Yuan, didn't I say that I got the Ice Demon Spring? But this time I didn't get one drop or two drops, but a little more. ”

Ning Yuan, who was originally still disappointed, heard Ling Mu's words, and suddenly shook his whole body, and asked with some trembling, "Ling Mu, what do you mean kid......

"That said, I still have a lot of Ice Demon Springs. ”

After speaking, Ling Mu took out a bottle of Ice Demon Spring, which was not big but full of ten drops, which was enough for a person's life.

"Elder Ning Yuan, these Ice Demon Springs will be given to you, but you must keep them secret for me. I'll give it to Elder Wen Ze personally. Ling Mu admonished, after all, the fewer people who knew about this kind of thing, the better, and besides, among the nine elders of the Ancient Sword Sect, there might still be traitors.

After taking Ling Mu's Ice Demon Spring, Ning Yuan looked a little excited, "Don't worry, I will never reveal it to the second person, you have to be more careful yourself, remember not to expose it." ”

No matter who knew that Ling Mu had a lot of Ice Demon Springs, he would immediately ask him not to talk nonsense.

After all, the Ice Demon Spring is too tempting, the Fountain of Life at the beginning of the birth of the world, even if it is an old monster that is about to enter the earth, it only takes a drop to live for a hundred years.

Of course, one drop or two of others may not be able to snatch it from you, but Ling Mu has such a large amount, it is a very terrifying existence.

Of course, Ling Mu didn't tell anyone the number of his Ice Demon Springs, because there were so many that no one believed Ling Mu when he said it.

Elder Ning Yuan's Ice Demon Spring was just about to go back to retreat, when he suddenly thought of something, turned around again, and said to Ling Mu with some embarrassment: "Ling Mu, do you have time to help me clean up the Spirit Sucking Grass in this medicine garden." ”

The effect of the land that Ling Mu had cleared last time was really good, and the elixir had grown six times faster, making Ning Yuan's mouth smile crookedly.

However, there was only that one, and before other places could deal with it, Ling Mu went to the Beihai Demon Cave.

But fortunately, now Ling Mu is back, and he has returned with so many Ice Demon Springs.

Ling Mu looked at it, he was now needing a large amount of spiritual energy, and the spiritual sucking grass seeds in this soil were having spiritual energy, although there was very little spiritual energy in a seed, but there were so many places in this medicine garden, the number of spiritual sucking grass seeds was a very terrifying existence.

As long as Ling Mu was able to absorb them all, it would not be a problem to break through to the fifth level of the Huang Yuan Mirror.

"Okay, Elder Ning Yuan, even though you are in retreat and cultivating, leave it to me here. Ling Mu agreed to it, which was beneficial to him.

Ning Yuan nodded, "Then I'll leave it to you here, I'll go to retreat." ”

As for taking the Ice Demon Spring, Ning Yuan was a little impatient, his two thousand years of injuries were likely to heal in a short time.

After speaking, Ning Yuan returned to the room where the demon vine was incarnated.

Ling Mu did not delay, but came directly to the middle of a field.

Ling Mu closed his eyes and felt the aura of this heaven and earth, and soon Ling Mu found those spiritual sucking grass seeds buried in the ground.

"Gather!"

Ling Mu used the "Spirit Swallowing Technique" to mobilize the aura between heaven and earth, and all the aura around him was converging towards Ling Mu's dantian.

Ling Mu's dantian seemed to have a powerful suction, not only was the spiritual energy between heaven and earth sucked away, but even the spiritual sucking grass that grew outside was also sucked away and gradually withered.

However, Ling Mu did not absorb all of them without a bottom line, the sky only absorbed the spirit absorbing grass, as for the elixir, Ling Mu didn't dare, these were all Ning Yuan's treasures.

Slowly, all the surrounding spiritual sucking grasses withered and died, and Ling Mu extended the scope of spiritual energy absorption to the land.

Beneath the ground, there are countless soul-sucking grass seeds, which are always waiting to germinate.

But this time they didn't have a chance, and the only trace of aura left in their seeds was seized by a strange force.

They were powerless to resist, and the moment the aura was taken away, they were completely dead and would never sprout again.

With the soles of Ling Mu's feet as the center, the spirit sucking grass seeds buried in the ground began to die slowly, first one foot, then one zhang, and in this way, slowly In the land within a radius of ten miles around Ling Mu, there was no longer a seed of spirit sucking grass.

All the seeds were seized by Ling Mu and died, while Ling Mu's own obtained a large amount of spiritual energy, and the fourth drop of spiritual liquid in the dantian gradually became full.
