Only then did he put the dragon scale flower into the ring, and when he looked up, he suddenly saw a large clump of red grass.

"Dragon Vein Grass!"

Li Mo rushed over with an arrow step and couldn't help but laugh a few times.

It's really hard to come by, who would have thought that there really is such a treasure in the underground of this dangerous place where countless mysteries were buried.

Moreover, this must be another place where the entrance is inaccessible, so the materials that grow here are not obtained.

Don't look at these flowers and plants are only eight or nine inches long, but these things are all a hundred years long, that is to say, every grass and tree is a thousand years old.

Xiao Hei also screamed happily at this time, nibbling on a bunch of flowers and plants.

Li Mo couldn't help but smile when he saw it, these things born from dragon qi were great supplements for Xiao Hei, who was not a purebred dragon, and there were a lot of these things, so he didn't need to be stingy, just let it eat enough.

The further you go, the more dense all kinds of exotic flowers and plants become, and there are few plants in the outside world, but here they are growing in large clusters.

Even if Na Yuanzhu couldn't absorb the power of Longyin Tianhe, taking out these materials would be enough for those stewards to obediently write a letter of recommendation.

Go deep all the way, and harvest a lot along the way.

Half an hour later, a light suddenly flickered ahead.

Li Moding looked at it, and immediately sighed lightly: "Dragon Qi Earth Fire!"

When the words fell, he couldn't help but get excited, and rushed over in three steps and two steps, grabbing the dragon qi and earth fire in his hand.

The blue earth fire is like a small dragon coiled together, circling and circling, vivid, as if it is about to break free from the palm of its hand at any time.

Li Mo immediately took out the Dan furnace and stuffed the dragon qi earth fire, dragon scale flower, dragon vein grass and other materials into it.

After that, the Nine Towers were sacrificed to refine the fire technique, and the elixir was refined on the spot.

The dragon qi earth fire is the best of the earth fire, it is absolutely rare in the world, even the chalcedony earth fire has no room to compare with it at all.

It takes decades for the average person to consume it.

And even if Li Mo had a third-class spirit bone body, he didn't dare to swallow it hard.

This thing has a very strong ferocity, and once it is detected that it is imprisoned in the body, it will smash the whole body to pieces.

To swallow it is to kill yourself.

Therefore, the ancient predecessors have long studied the best way to absorb the dragon qi and earth fire, that is, to use various spiritual materials to refine the dragon qi and earth fire into pills.

Naturally, the Cheng Dan process requires absolutely superb skill.

But once it becomes a pill, the ferocity of the dragon's qi and earth fire will disappear completely, and it will be controlled by people.

Li Mo was engrossed in refining the elixir.

Dragon Qi Earth Fire is not easy to come by, and once it fails, there is no possibility of finding it.

Li Mo also showed an unprecedented cautious look, sacrificed the chalcedony earth fire, and devoted himself to the alchemy process.

The whole person seems to be one with the Dan furnace, and Lingtong can see the changes in the materials in the furnace at the moment.

Time passed slowly, and on this vast spiritual material land, he was the only one sitting quietly here.

Xiao Hei ran happily around the area, looking for all kinds of food.

It wasn't until half a day later, when the danxiang overflowed, that Li Mo's cautious expression relaxed a little.

When the Dan was completed, Li Mo opened the lid of the furnace and saw an Earth Fire Pill lying quietly in the middle.

"It's finally done. ”

Exhaled lightly and wiped half a drop of sweat oozing from his forehead, Li Mo completely relaxed.

Then, he swallowed the Dragon Qi Pill into his mouth in one gulp.

In an instant, Dan shattered the dragon, and a pure earth fire power erupted, permeating the whole body.

And the earth fire is more like a living thing, stretching its body with teeth and claws in its body.

Li Mo was secretly surprised, he didn't expect that even if this thing was no longer ferocious, it still had such a strong instinct.

He hurriedly gathered his true qi to control it, and then slowly sent it towards his abdomen.

Even if the earth fire becomes a pill, the power it contains is unimaginably huge.

There seemed to be a big mountain pressing on his shoulders, and people couldn't help but secretly breathe.

Li Mo mobilized ten percent of his true qi and pressed the earth fire towards his abdomen.

Every nerve, every meridian was straightened, as if it would break at any moment.

Rao is Li Mo, and he is also under considerable pressure at this time.

But more than that, it is the fighting spirit that will never admit defeat.

Inch by inch, inch by inch, it took more than half an hour for Li Mo to finally incorporate the dragon qi and earth fire into his belly.

At this time, the dragon qi earth fire instinctively wrapped the triple chalcedony earth fire, and then there was no longer any abnormal movement.

Li Mo stood still, letting his body slowly adapt to the impact of the ground fire, and only after he was completely accustomed to it did he let out a long breath with a smile on his face.

Now, as long as you wait until the dragon qi earth fire slowly devours the triple chalcedony earth fire, then the dragon qi earth fire will directly grow into the quadruple realm, helping you become a ground-level second-grade Dan master.

Then, Li Mo stood up.

looked left and right, and suddenly found that Xiao Hei was gone.

But there was only one way, and he didn't have to worry, so he walked slowly forward.

There are still a lot of exotic flowers and plants along the way, Li Mo picks them all the way, and the vast underground world extends downward, forming a valley.

Walking into the valley, all kinds of flowers and plants disappear, replaced by boulders of various forms.

Soon, Li Mo heard the sound of "click".

He immediately walked briskly, and saw that in the corner of the valley, Xiao Hei was munching on something.

When Li Mo got closer, he looked at it, and it was suddenly a bone.

The broken bones seem to have gone through an extremely long time, revealing the vicissitudes of life, but they still exude an unusually powerful aura, and there are mysterious lines on the bones.

"Keel!"

Li Mo blurted out.

No wonder Xiao Hei ran away in the morning, this little thing smelled the keel.

That means that this is really the place where the blue-eyed water dragon died, otherwise how could there be a dragon skeleton?

As he thought so, Xiao Hei's body suddenly emitted a dense black light, thick as liquid, and when it swallowed the last bone in its mouth, the black light suddenly expanded.

Black light enveloped its entire body, making it look like a black ball of light from a distance.

Li Mo knew that Xiao Hei was evolving towards an adult body, so he stood quietly in the distance, and at the same time deeply felt the powerful power contained in the dragon bone.

At the current growth rate of Xiao Hei, it will take at least a few years to enter adulthood.

However, through guò devouring the keel, Xiao Hei was able to cross the gap of several years.

It didn't take long for the black ball of light to solidify, like a pitch-black eggshell.

Then, the eggshell cracked, and a black, robust adult Dark Dragon was born.

The body is ten feet long, and the thick black scale armor covers the whole body, and the scars left in the past are gone, as if the physical body has been perfectly transformed.

The sharp horns on that head also became two, longer and thicker, and more powerful at the same time.

"Roar—"

Like a black-armored warrior, Xiao Hei let out an excited roar, spread his wings and flew high in the air a few times before landing.

Li Mo smiled with relief, as if he had seen his child grow up.

However, adulthood is only the beginning of the growth of the dark dragon, as a dragon beast, this thing has a lifespan of thousands of years, far more than humans think, and once it enters adulthood, its combat power has also increased to the late stage of the Xuanyuan realm.

With growth, at the time of a hundred years, you can break through the realm and reach the heavenly dome realm.

After landing on the ground, Xiao Hei shook his body and regained his body like a big black dog.

Li Mo smiled slightly and asked, "Xiao Hei, where is the keel?"

Xiao Hei shrugged his nose and immediately ran forward.

Li Mo followed, and soon found another keel.

This dragon bone is more than ten zhang long, as thick as a bucket, it can be seen that the size of the water dragon is huge, at least hundreds of zhang long, compared to it, the lava behemoth is not comparable.

But unfortunately, there are too many cracks on it, and it can no longer be used as a material.

"I need the whole, I'll give you this one. ”

Li Mo said.

Xiao Hei wagged his tail happily, bit on the keel, and ate it deliciously.

Although the nourishing effect of the dragon bone on it is greatly reduced after being promoted to an adult beast, it is not known how much higher it is compared to ordinary minerals.

Eating a keel, it will not be a problem to increase the cultivation for a year or two.

With such a man and a beast marching in the valley, Xiao Hei couldn't digest too many keels in a day, so Li Mo threw all the broken keels along the way into the ring as food for Xiao Hei in the future.

However, most of the keels seemed to be buried deep underground, making it difficult to excavate, and Li Mo was lucky enough to find a few giant keels in good condition on the ground, which could be used as materials.

At the same time, in the place where the keel remains, there are also some rare minerals, all of which were obtained by Li Mo.

It can be said that this is an absolute treasure, with countless treasures waiting to be discovered.

But time is still quite tight for Li Mo, this underground world is too vast, God knows where the exit is.

Therefore, he didn't want to waste time until he found the exit, and now that three days had passed, if he didn't have time to find the exit, he would miss the game in the steward's field, and all his efforts would be wasted.

So he only took the important materials along the way, and waited until he found the exit before returning back.

The long valley stretched endlessly, and between the staggered extensions of the strata, white crystals protruded and shimmered brightly.

Suddenly, Xiao Hei's "Peng" reverted to his figure, and he let out a low roar.

At the same time, Li Mo also felt a subtle change in the atmosphere.

The cold hairs on his body stood up one by one, which was an instinct born of a long battle.

There must be something terrible ahead of this, otherwise it wouldn't be.

So, one man and one beast cautiously moved forward.

The surroundings are open, but the terrain is constantly lowering, and the atmosphere is becoming more and more solemn.

Li Mo immediately took out the Red Moon Bow, took the arrow, opened his Lingtong Eyes, and observed the situation within ten zhang.

Suddenly, he sensed a force piercing at high speed from below.

Fast, fast to lightning.

Li Mo quickly retreated, no need to say hello, and Xiao Hei dodged at high speed.
