Yun Tian naturally knew that the red blood grass was highly poisonous, and he didn't dare to pick it off with his hands, but with a wave of the Kunyu sword, a stream of sword qi shot out, and a big hole appeared in the ground, and the red blood grass flew up.

As soon as it left the soil on which it depended, the red blood grass seemed to have lost all its provisions, and the red light on the grass disappeared in vain, leaving only a small grass floating in the air.

With a wave of his hand, Yun Tian grabbed this red blood grass. The red light of the red blood grass is highly toxic, and now that the red light has dissipated, it is naturally not toxic, otherwise how to use the medicine.

If it is poisonous, it can also be refined into some poison pills.

"Whew, what a rich blood!"

Taking a deep breath, Yun Tian felt the thick qi and blood, and he was overjoyed, put away the red blood grass, and Yun Rou continued to walk deeper.

Getting a grown red blood grass, this is pure good luck, with this red blood grass, Liu Yun is completely able to refine a "red blood pill", with this pill, Yuntian's qi and blood spirit will increase a little, why not?

There are not many medicinal materials, the more medicinal materials the better, the more medicinal materials, the more elixirs refined, and the more effects there are.

Yun Tian and Yun Rou had just left the place where they were picking grass, and the space here suddenly distorted at a speed visible to the naked eye, and finally turned into two large eyeballs.

These two eyeballs are not the same, one eyeball is pitch black, eerie and exudes a rolling demonic aura, at first glance, it is a product of the Demon Dao Sect.

There is also an eyeball that is milky white, the light on it flickers, and the bursts of nine-colored glow flash on the eyeball, like a nine-color rainbow, full of fairy energy, and it is a fairy thing at a glance.

These two hugely different eyeballs glanced at each other at the same time, and then each seemed to let out a cold snort, and they didn't pay attention to each other, but set their eyes on Yun Tian and Yun Rou in the distance.

Even if Yun Rou is a cultivator of the Jindan Realm, he did not find the existence of these two eyeballs, which shows that these two eyeballs are much more powerful than Yun Rou.

After a long time, the two eyeballs blinked and watched Yuntian and the two disappear from sight, and then the two eyeballs looked at each other again, the light in their eyes flickered, and the space was infinitely distorted under their gaze, and a big battle seemed to happen at any time.

"Old man, you have been with me for tens of thousands of years, and now that my destined person has come, you can't trap me anymore, and when I go out, I will kill the dragon realm and kill the dragon clan cleanly, especially the dragon that suppressed me back then, I want to let him break his body into ten thousand pieces." ”

This pitch-black eyeball, looking at the milky white eyeball next to it, suddenly emitted a vast, ancient, vicissitudes of sound fluctuations.

"Okay, do you think that with your current strength, you can find the gate of the Dragon Realm? Even if you find the gate of the Dragon Realm, you will only be completely dead, you still stay here obediently, waiting for your destined people to rescue you!"

The white eyeballs smiled disdainfully, and there was also a wave of voice fluctuations, "Besides, your destined person is here, my destined person is also here, and I may not be able to trap you, but now is not the time to say this, the Emperor of the Underworld sent you here, and naturally he has his plans, you should be careful, so as not to cause the anger of the Emperor of the Underworld." ”

"I don't need you to say this, my current strength is not as good as one ten-thousandth of what I used to be, but as long as I break this sealing array, I will have thousands of ways to restore my strength, and I will definitely beat you all over the ground when the time comes.

The black eyeballs didn't admit defeat at first glance, and the eyeballs blinked.

"That's not necessarily, don't forget, my body has already come, as long as I fuse the body, you will only be plundered. The white eyeballs said lightly.

"That's true, but you'll only be able to recover half of your power, and it's almost impossible for you to defeat me completely. ”

..........

After a long time, the two argumentative eyeballs suddenly turned into two fine lights, and disappeared into thin air as if they had never appeared.

The conversation between these two eyeballs, Yun Tian and Yun Rou naturally didn't know, at this time, Yun Tian encountered another treasure, this treasure is still a medicinal material, but this medicinal material is very special.

At this time, not far in front of Yuntian, there was a small underground lake, and in this lake was not water, but ice. Yes, it's ice, a kind of ice that exudes a biting chill, and in the center of this lake, there is a transparent crystal more than a foot high.

This crystal is a foot high, and the cold air is surging on it, just like an ordinary ice crystal, but inside this ice crystal, there is a turquoise grass like a tree branch.

This turquoise grass resembles a branch, with no roots or leaves, and is completely bare, which is particularly mysterious. And the twig-like grass glowed green, which was particularly dazzling in the ice.

Looking at this bare grass, Yun Tian and Yun Rou glanced at each other, and they could see the surprise in each other's eyes, as if this turquoise grass was a great treasure.

"Heavenly Jade Cold Ice Core! This is actually Heavenly Jade Cold Ice Core!" Yun Tian said with a slight shock as he looked at the turquoise grass.

The "Heavenly Jade Cold Ice Core" is not jade, but a kind of grass, that is, the grass wrapped in ice in front of Yuntian's eyes.

This grass does not have the slightest feeling of grass and trees, but feels like jade, so it has the name of Tianyu, which is naturally beautiful. And Tianyu is wrapped in ice, like an ice core, so it has the name "Tianyu Cold Ice Core".

The medicinal herb of Tianyu Cold Ice Core only grows in the 10,000-year-old ice, and lives by absorbing the essence of the 10,000-year-old ice.

Once the marrow of ice is formed, the heavenly jade will turn into a turquoise color, and the cold is pressing, and a trace of cold can freeze a piece of land.

This herb has only one effect, which is to increase the flexibility of the bones, and it can purify the bone marrow, making it as transparent and pure as ice. To put it bluntly, the Tianyu Cold Ice Core is a kind of medicinal material for refining the body.

This herb is extremely rare, countless times rarer than the Red Blood Grass, and it is rumored that it is only found in the depths of the ocean.

And now that this medicinal material has appeared in the ground, can Yun Tian not be surprised, but he didn't think about why, as long as the medicinal material is in hand, there is no point in caring about the rest.

Yun Tian nodded to Yun Rou, Yun Rou understood, and an invisible mana poured out of her body, and with just one blow, she broke through the 10,000-year-old ice in the 10,000-year-old cold ice lake, which was harder than steel, and turned into countless ice crystals, fluttering in the wind, Yun Rou's heart moved, and grabbed the Tianyu cold ice core that was more than a foot high in the center of the lake.

Without the slightest hindrance, the mana hand easily grabbed the Tianyu cold ice core wrapped in ice, and then landed in front of Yun Tian's eyes, and suddenly, Yun Tian felt a piercing chill, as if his blood was frozen.

As soon as Yun Tian's spirit moved, he blocked this chill from his body, and then with the help of Yun Rou, he put the cold ice core with the cold ice into the space treasure bag.

The 10,000-year-old cold ice can completely freeze and shatter the steel, and the physical body can't get close at all, so Yun Tian will let Yun Rou use his mana to collect the jade cold ice core of this day.

And the cold ice wrapped around the Tianyu cold ice core also has the effect of protecting the medicinal properties, so Yun Tian will put the cold ice into the space treasure bag together, otherwise after a few months, the medicinal power of the Tianyu cold ice core will be lost a lot.

After collecting the Tianyu Cold Ice Core, Yuntian did not stay, and continued to walk towards the depths of the earth, this journey was extremely peaceful, and he did not meet a single demon beast or earth demon at all, but found a lot of medicinal materials.

The quality of some medicinal materials is not even below the cold ice core of Tianyu, such as "Nine Turns Cold Lotus", "Nine Light Grass", "Condensing Grass" and so on.

Along the way, Yun Tian collected hundreds of medicinal herbs, all of which were medicinal herbs that were more than a thousand years old, and this underground world was completely a natural medicine garden in his eyes.

And the deeper you go, the more types of medicinal herbs there are, and these visible benefits are accepted by Yun Tian one by one.
