Li Muran and the others stayed in front of the second layer of the seal for several months, and after being unable to break or wear down the seal here by various methods, they could only return in a huff.

Only Hua Yuncong stayed here, closely monitoring the changes in the seal here to confirm his previous inference that the power of the seal was slowly weakening, and in hundreds of years, it would reach a low point.

Li Muran returned to the cave mansion located in the dense forest and continued to meditate and cultivate.

The mysterious grass was slowly growing, its seventy-ninth leaf had matured, just like the others, and the eightieth leaf was still a young shoot, showing no signs of blooming at all.

Since it would take a long time to break the power of the seal, Li Muran chose to retreat and cultivate. Not long after he advanced to the late stage of the Yuan Shen, the fourth layer of the Taixu Sutra was also being cultivated, and the Demon Gate Alchemy Technique had just been completed, and there was still a lot of room for improvement in all aspects, and it did take a long time to practice.

And the environment of this demon land is quite uncomfortable for Liu Chenfeng and other spiritual cultivators, but for Li Muran, there are also advantages and disadvantages, and there are some unique cultivation environments that cannot be found in other parts of the spiritual world.

This sealed land is extraordinarily calm, and the high-level demon beasts have basically been killed by all the sword cultivators, and there is nothing sinister here, and they cannot pose a fatal threat to these sword cultivators.

There is no conflict of interest between the sword cultivators, they are all disciples of the same sect, and they already have the same affection, plus the agreement between them under the leadership of Li Muran before, they will not do anything to each other.

As a result, everyone cultivated separately, and occasionally they would learn from each other to verify the exercises, and everyone regarded this sealed land as the Heavenly Sword Valley, but this place was even more silent than the Heavenly Sword Valley.

Unlike Li Muran, the cultivation of these sword cultivators was mostly concentrated in a few large spirit valleys. As for those magic valleys, except for the occasional person who went to investigate and see if there were any treasures to discover, no one cared about them for a long time.

Not long after, even Hua Yuncong gave up the idea of leaving here early, he left a few monitoring formations before the second layer of seals, and then returned to the Spirit Valley to practice.

Gradually, everyone was cultivating, except for the Spirit Valley, where many disciples had gathered somewhere, no one walked around such a large sealed place, as if these disciples had never come.

The sun, moon and stars are not visible in the sealed place, but there are also changes in light and darkness. When it is brighter, it is day, and when it is darker, it is night. The time of day and night is no different from the outside world. It is expected that the passage of time here is no different from the outside world.

Ten years and ten years have passed, except for the continuous improvement of everyone's cultivation, it seems that nothing has changed. However, the power of the seal here is also slowly weakening as Hua Yun expected, and it seems that as long as you wait enough time, when the power of the seal reaches a low point, it is indeed possible to leave here.

Two hundred years have passed.

The cultivation of all sword cultivators has somewhat improved. The first to advance was the fifth disciple Nie Xin, who advanced to the middle stage of the spirit body after less than sixty years of penance; after another few decades, the tenth disciple Wu Heng and the eleventh disciple Fang Tianao had both advanced to the early stage of the spirit body, and only the ninth disciple Zhang Zijing was still trapped in the peak realm of the late stage of the Yuan Shen Dynasty and failed to break through the bottleneck.

Decades ago, the eldest disciple Liu Chenfeng, the third disciple Sword Idiot, and the sixth disciple Meng Li also advanced to the middle stage of the spirit body, and only the fourth disciple Hua Yuncong delayed a lot of time because of the study of the formation and failed to advance, however, these disciples are all extremely talented, as long as time is given, Hua Yun will inevitably advance from the middle stage of the spirit body.

The news of the advancement of these disciples came frequently, which made Li Muran quite amazed and envious. The Heavenly Sword Old Man really has a set of disciples to select, his vision is really sharp, almost all of these disciples can advance to the spiritual body stage and continue to improve their cultivation, maybe in the distant future, some of them will be able to advance to the Mahayana stage!

Li Muran has also cultivated to the peak of the late stage of the Yuan Shen Dynasty from just advancing to the late stage of the Yuan Shen Dynasty in the past two hundred years, but he has not yet felt the opportunity to break through to the Spirit Body Stage. Generally speaking, it is not an overnight achievement to maintain the realm of the peak of the late Yuan Shen period for a long time before you can gradually gain a sense and finally break through the bottleneck.

After two hundred years of penance, everyone has greatly increased their cultivation, and their strength has naturally increased a lot, while the power of the seal is weakening. It is not impossible to break through the seal and leave here in another three to five hundred years.

That mysterious little grass also has ninety-nine eighty-one leaves. Li Muran's estimate is roughly not bad, this grass only grows a new leaf every ninety-nine years, and every time it grows leaves, it will usher in a catastrophe. After the eighty-one leaves had grown, there were no young shoots in the grass, but a pink bud appeared at the top of the grass not long after.

Since the emergence of this bud, the growth of the grass has changed dramatically. Every month, the leaves of the grass will turn yellow and fall off one piece, starting at the very bottom. As soon as these leaves fall off, they turn into wisps of green smoke and disappear on their own. Li Muran wanted to collect this mysterious leaf, but he couldn't do it.

With each leaf dropping, the bud grows a little. Li Muran curiously paid close attention to the changes in Xiaocao, and never left.

On this night, the last leaf finally turned into a wisp of green smoke and dispersed, and the bud grew to the size of an inch. However, the buds are still buds and do not bloom.

Li Muran quietly looked at this slippery little grass, with an inch-sized flower bud on the foot-long stem, which looked very strange.

Suddenly, Li Muran found that the stems of the grass began to turn yellow, at first it was just a small yellow dot, but then it spread very quickly, and when Li Muran noticed this scene, the stems of the grass were almost all yellow and were withering!

And the buds, actually slightly opened, seem to have signs of blooming.

Li Muran is very curious, the blooming buds are a symbol of vitality, but the leaves of this grass are all lost, the rhizomes are withered, and the two are obviously lacking in vitality, why is this contradictory?

What is even more surprising is that it is not only the rhizomes of this little grass that are withering, but all the trees in the surrounding dense forest are withering extremely quickly.

Almost in the blink of an eye, when Li Muran turned around, he saw that several thousand-year-old trees behind him had withered and lifeless, and they had turned into ashes and collapsed.

Li Muran flew into the air in shock, and as far as he could see, the withering was surging around like a tide, and a forest with a small range of areas almost disappeared between a few of them, and where the tide of death passed, there was no vitality!

Even the Thunder Spirit Tree, which was extremely vigorous and at least thousands of years old, turned into a wisp of green smoke at this time and collapsed.

Li Muran was horrified, in this dense forest, the only thing that still has a glimmer of life is this mysterious grass. And the grass obviously couldn't last long, his rhizomes were already withered and blackened, crumbling, as if it only took a wisp of wind to blow through it, and it would be wiped out!

What's even more incredible is that the buds are becoming more and more delicate, and the petals are gradually opening and blooming!

In the midst of a lifeless desolation, only a strange flower bloomed, and this scene was very strange.

"Ah, I understand!" Li Muran's heart suddenly moved, and he thought of something.

"It must be that the vitality needed for this strange flower to bloom is too strong! It should not appear in this realm at all, and the vitality of this realm cannot support its smooth opening, so it has drained the vitality of all the surrounding trees, and even its own leaves and rhizomes are not spared, but it is still difficult to bloom!"

"It's a pity that this strange grass shouldn't be here at all. It has gone through eighty-one catastrophes and lived hard for more than 8,000 years, but it is still unsustainable, and now it is about to be short-lived!"

Li Muran knew in his heart that when this flower blooms, it will run out of vitality, it will bloom vigorously, and then wither and wither.

Sure enough, before the sky was getting brighter and the 'day' of the sealed land was about to arrive, the flower finally bloomed, revealing seven petals and eighty-one thin stamens. However, at this moment, its rhizome finally could no longer support it, turned into a wisp of green smoke, and collapsed and disappeared.

The strange flower slowly fell to the ground, Li Muran guessed that the so-called Taoist law is natural, and things return to their originals, as long as the petals fall to the ground, they are likely to collapse again, turn into a majestic vitality, and return to this land.

And this spirit grass spirit flower will also disappear completely, ending its life cycle that should not have appeared here in the first place!

Li Muran's sleeve robe waved slightly, and a breeze rolled up, holding up the strange flowers. The strange flower floats in mid-air, preventing it from touching the earth.

However, the strange flower is also withering very quickly, and it will only take a moment for it to return to heaven and earth. Li Muran can only delay this process slightly at most, but he can't reverse it!

"Unless—" Li Muran's heart moved, and then he opened his mouth to swallow this strange flower!

"Unless I let it die in my body, let the powerful power it contains be absorbed by my body! In this way, it will not return to heaven and earth, but will be absorbed by me and merge with me!" Li Muran said secretly in his heart.

Li Muran was quite nervous, he didn't dare to forcibly refine this strange flower at all, he could only let it slowly release that amazing vitality in his body.

Li Muran's doing so is extremely risky. He didn't know at all whether his body would be able to withstand the powerful life contained in this strange flower, and he didn't know what the consequences would be after refining this flower. But he knew that this flower was a flash in the pan, and if he did not swallow it immediately, it would disappear and collapse and return to heaven and earth—and he would probably never get such an opportunity again!

When the strange flowers entered the body, Li Muran immediately closed his eyes and sat down cross-legged, running the exercises and protecting his mind!
