Grassroots Immortality

When Lin Xian saw the Soul Devouring Tree, his pupils shrank. The Soul Devouring Tree suddenly grew taller. According to the previous growth progress, it was impossible for this Soul Devouring Tree to grow to such a degree.

At this moment, Lin Xian was surprised, but he also began to ponder.

In just a cup of tea, Lin Xian had a flash of inspiration.

After that, he slowly walked to the side of the Soul Devouring Tree and took out the dozens of crystals he had just collected.

When the crystal appeared, a not-so-obvious suction force suddenly appeared, and a trace of green light slowly floated towards the Soul Devouring Tree like a green silk thread.

Finally, it sank into the Soul Devouring Tree. Seeing this, Lin Xian opened his mouth slightly and felt incredible.

This situation continued, but after about two days, the twelve crystals turned gray.

There was no green "silk thread" emerging from them, and they became the most ordinary stones, just like the crystals collected at the beginning.

Lin Xian finally found the reason. Seeing the crystals turn gray, Lin Xian did not feel distressed.

Because after absorbing the green "threads" in these crystals, the Soul Devouring Wood grew a little bit.

This speed is obviously faster than the natural growth of the Soul Devouring Wood.

After finding the reason and drawing the conclusion, Lin Xian has found one benefit of these crystals - that is, they can become the "nutrients" of the Soul Devouring Wood and accelerate its growth.

With this conclusion, these crystals have undoubtedly become treasures in Lin Xian's eyes, and they are not ordinary treasures.

You know, even if the Qiankun Mirror absorbs the Magic Source Pearl, the growth rate of the Soul Devouring Wood will be accelerated again.

But if they want to become timber, Lin Xian still has to wait at least a hundred years.

Although this time has been greatly shortened, it still feels a bit long for Lin Xian to wait for a hundred years.

But now there is this kind of crystal as nutrient, as long as there are enough crystals, the time for the Soul Devouring Wood to become timber will be greatly shortened again.

Lin Xian doesn't know to what extent it can be shortened, and it also depends on the number of crystals.

Therefore, Lin Xian did not know the specific time, but he knew that as long as he continued to collect crystals and let the Soul Devouring Wood absorb the essence, Lin Xian knew that the result would most likely be a surprise to him.

Lin Xian was recovering his mana in the wooden house. The battle with the Nether Beasts consumed a lot of energy, and it was impossible to recover mana in the Nether Valley.

Even if it was a top-grade spirit stone, the recovery speed was extremely slow.

In the end, Lin Xian simply output all his strength, and after the killing was completed, he directly entered the Qiankun Mirror to recover.

This way, the recovery speed was much faster, and a lot of time could be saved.

After his mana was restored to its original state, Lin Xian appeared in the Nether Valley again.

After discovering the role of the crystals on the Nether Beasts, Lin Xian was also very surprised.

At the same time, Lin Xian was also sighing that if he did not come to the Nether Valley, he would have to wait for hundreds of years for the Soul Devouring Wood to become a material.

In the following time, Lin Xian was not in a hurry at all.

From the initial disgust for these underworld beasts, he also turned to looking for them inch by inch.

When one gap came to the end, Lin Xian turned around and walked towards another gap.

He was going to kill all the underworld beasts in the Nether Valley.

Lin Xian did not take the same path, but he also killed a large number of underworld beasts and obtained a large number of crystals.

These crystals were treasures in Lin Xian's eyes. This time when he came to the Nether Valley, as long as he could get enough crystals to make the Soul Devouring Wood mature as soon as possible, this could be said to be his biggest gain.

When Lin Xian walked out of a gap, the scenery in front of him suddenly changed. The terrain that was originally full of high peaks turned into low hills like hills.

Lin Xian knew that this should be another place in the Nether Valley.

Lin Xian did not hesitate, but just remembered this road.

Then he turned around and walked back, because there were many gaps behind that he had not been to, and there should be many underworld beasts in them.

Now, these underworld beasts are no different from the treasure in Lin Xian's eyes, and he certainly doesn't want to let any underworld beast go.

In this way, Lin Xian cleaned up the underworld beasts one by one, as long as he wanted to get the crystals on them.

When the mana was consumed by half, Lin Xian would enter the Qiankun Mirror to restore his mana, and at the same time put the crystals he got at the roots of the four soul-devouring trees.

When Lin Xian recovered his mana, he left the Qiankun Mirror again and continued to look for underworld beasts.

The strength of the underworld beasts was not very strong, anyway, the underworld beasts that Lin Xian encountered were like this.

Under the attack of the soul-devouring mirror, almost no underworld beast could resist, and they would soon be killed by Lin Xian.

Compared with the demon beasts, the flesh of the underworld beasts was also much weaker, and their attack method almost relied on the unique underworld energy attack.

Of course, there were also those who relied on the flesh to attack, and such attacks became very threatening to Lin Xian.

Lower-level Nether Beasts cannot drive Nether Qi at all, and they can only use their bodies to attack, while higher-level Nether Beasts have learned some methods to drive Nether Qi, and can also use Nether Qi to launch more powerful attacks.

These attacks are not much of a threat to Lin Xian, so, since entering the Nether Valley, Lin Xian has not encountered any trouble at all except for restoring his mana many times.

Lin Xian seems relaxed, but if you think about it carefully, if there is no such heaven-defying treasure as the Qiankun Mirror, Lin Xian would not dare to act like this.

Even if these underworld beasts can't pose much threat to him, he will always run out of mana and eventually die in the Nether Valley.

When Lin Xian appeared in the Nether Valley again, this gap was obviously several times wider than other gaps.

The width of ordinary gaps is only about ten feet, but this gap is several feet wide, and the number of underworld beasts in this gap is far more than other gaps.

Although he felt that this gap was a little different, Lin Xian didn't care much. As long as there were underworld beasts here, he would kill them all.

Recently, the soul-devouring wood in the Qiankun mirror has grown well, all thanks to these crystals. Such a treasure, Lin Xian will certainly not let it go.

When the mana was exhausted, Lin Xian also entered the Qiankun mirror again to restore his mana. This gap is the gap where Lin Xian has gained the most since entering the Nether Valley.

Lin Xian entered the Qiankun mirror three times just to restore.

This is the fourth time. Lin Xian has gone very deep into this gap and also felt a stronger underworld aura.

Lin Xian also had a vague feeling in his heart that this gap seemed to be a little different, so he was also very careful. As long as 60% of his mana was consumed, he would start to enter the Qiankun Mirror to recover.

If he encountered an unexpected situation and his mana was insufficient, it would not be worth it.
