Grassroots Immortality

Lin Xian explored this hilly area and also harvested three materials that were useful to him.

When he approached a different mountain, Lin Xian was also happy, but also a little hesitant.

The difference of this mountain is that its height should be the highest mountain in this area. Not only that, Lin Xian also felt a more concentrated underworld energy on this mountain.

Lin Xian felt that there must be the materials he needed on this mountain.

Why did Lin Xian hesitate? Of course, it was because he also felt a very strong breath on this mountain, which should be emitted by a powerful underworld beast.

The demon hunter had just fought with the hell demon dog for a long time, and its own consumption was quite serious. It was also a matter of two things to say whether it could help him.

Lin Xian could judge from the breath emitted by this underworld beast that the strength of this underworld beast would definitely not be weaker than the hell demon dog.

If he really encountered this underworld beast, he could defeat it, but Lin Xian was not sure in his heart.

However, after seeing the effect of the soul crystal of the hell demon dog, the attraction of this underworld beast to Lin Xian was undoubtedly irresistible.

After killing the hell demon dog, Lin Xian also placed its soul crystal at the root of the soul-devouring tree. Now, this soul-devouring tree has obviously grown faster than the other three soul-devouring trees.

This also shows that the higher the quality of the soul crystal, the faster the soul-devouring tree grows.

Not all soul crystals have the same effect.

Lin Xian finally couldn't resist the temptation. He also had confidence that even if he couldn't defeat this underworld beast, it would be no problem to escape. As long as his life could be guaranteed, Lin Xian decided to give it a try.

Lin Xian first used the Qiankun Mirror to completely converge his own breath, and then his figure flashed and shot towards the mountain.

In fact, it is called a mountain, or just a hill, just a little higher than the other hills.

Lin Xian roughly estimated that this so-called mountain was only a few dozen feet high, and it was estimated that it didn't even reach a hundred feet.

Lin Xian has come to the foot of the mountain. He plans to collect some minerals in the mountain first. If the underworld beast is really difficult to deal with, he can only slip away.

At that time, at least he did not return empty-handed, and he got some materials.

Lin Xian released his divine sense and explored carefully, not letting go of an inch of the place.

The underworld energy here is so rich that it must be able to breed some special materials. Lin Xian originally came for these materials.

Now that he has discovered the role of soul crystals, of course he hopes to get more soul crystals.

Lin Xian used a long sword to carefully dig in the mountain. After digging out a cave of about ten feet, Lin Xian held a basin-sized ore in the cave with a smile on his face.

This is a piece of underworld silver crystal, which is also a material needed to refine the painted sky halberd.

The scale of this mountain is not large, and Lin Xian has sensed the location of the underworld beast.

The underworld beast seems to be in a cave halfway up the mountain, which should also be where his nest is.

At this moment, Lin Xian had no intention of looking for the Nether Beast. He would not bother the Nether Beast unless he searched the entire mountain.

Lin Xian used the Qiankun Mirror to restrain his own aura to the extreme, carefully exploring every inch of the place, fearing that he would miss a chance to find materials.

Lin Xian came to a place on the mountain, and suddenly, a hint of joy flashed across his face.

After that, his body slowly sank into the ground.

Earth escape technique!

When Lin Xian's body sank to a distance of about eleven feet underground, he also saw a group of Nether Gang silver ore.

Lin Xian took out his long sword, waved it for a while, and dug a big hole in the ground.

Looking at the Nether Gang silver ore in the center of the big hole that was as high as a person, Lin Xian was excited.

So much Nether Gang silver was enough for him to refine the Huatian Ji more than ten times.

Lin Xian certainly would not think it was too much, and directly put this piece of Nether Gang silver into the space of the Qiankun Mirror.

After putting away the Dark Silver, the entrance of a cave appeared in front of Lin Xian as expected. At the same time, an extremely dense Dark Qi rushed out of the cave, and Lin Xian couldn't help but shudder.

When he discovered the Dark Silver Mine, Lin Xian also discovered the existence of this underground cave, so when the cave entrance appeared, Lin Xian was not surprised at all.

Lin Xian did not hesitate, and jumped directly into the cave.

This is a natural underground cave, and the concentration of Dark Qi in it is also the most concentrated Dark Qi that Lin Xian has seen since entering the Nether Valley.

After entering the cave, Lin Xian found that there seemed to be an underground dark river here, and the river water exuded an extremely cold breath and flowed to the distance.

Lin Xian raised his head slightly and looked at the downstream of the river, and at the same time fell into deep thought.

About a meal later, Lin Xian looked up at the river again.

After that, he touched the storage bag with his right hand, and several giant ape puppets appeared in front of him. After that, the giant ape puppets jumped directly into the river.

Because Lin Xian had discovered that there was a material called Nether Crystal Sand in the river, which was also the material he needed for refining.

As for other things, of course he would consider them after he got these Nether Crystal Sands up.

Lin Xian also felt that the Nether Crystal Sands were all over the river. Although the amount was not large, the amount of Nether Crystal Sands increased as the river bottom went downstream.

For this reason, Lin Xian had to control the puppet and keep moving downstream. While salvaging the dark crystal sand, he looked around.

This underground cave seemed to be formed by the long-term erosion of this river. Lin Xian wanted to know where this underground river would eventually lead to, so he salvaged the dark crystal sand while slowly moving downstream.

A strong gloomy wind blew in his face. Even though Lin Xian was a Jindan cultivator, he felt a chill and got goose bumps unconsciously.

For this reason, Lin Xian was also quite surprised. A cultivator like him should not be afraid of cold or heat, and rarely have such a reaction.

I don’t know how long he has been walking downstream. Lin Xian has already obtained a lot of dark crystal sand, at least enough to refine the Huatian Halberd.

But Lin Xian still hasn’t seen the end of this underground river, but when Lin Xian saw the flowing river, he decided to move on.

The fact that the river water can flow also proves that the road ahead is not a dead end and there will always be an exit. Since there is an exit, Lin Xian is very curious about where the exit leads to.
