In the midst of the groaning, Su Han took the blood crystal the size of a skull that had been condensed by the blood mist of Nadiluo.

From this blood crystal, Su Han felt an indescribable earth-shattering vitality, which seemed to be condensed by qi and blood, and there was an astonishing red light churning within it.

However, this red light did not have the slightest drawback, and Su Han only had one feeling, and that was this blood crystal...... It is a treasure!!

"This thing ......"

Su Han took a deep breath, his eyes flashing: "If this thing is refined, what is refined is the qi and blood in it, and what is refined is the vitality in it!" ”

"Qi and blood are the foundation of people, vitality, and longevity!"

"If you use this alchemy, or swallow it directly, you may have ...... Enhance qi and blood, increase longevity! ”

Thinking of this, even with Su Han's knowledge, he couldn't help but breathe heavily.

In this world, if there is anything that is the most precious, perhaps many people have many opinions, because for them, the things they need are different, and the eyes of precious things are naturally different.

But there is no doubt that if you unify it, the thing that increases longevity is definitely the most precious!

Heaven and earth have extremes, longevity is limited, with the increase of cultivation, longevity will be more and more, but after all, it is not endless, sooner or later there will be a day, if you can't break through, it will still go with the passage of time, and gradually grow old, until death.

Especially for those who are powerful in heaven and earth, things that increase longevity can be called treasures!

Although they have an infinite lifespan, their cultivation also determines that it will be extremely difficult for them to break through again.

And once it can't break through, it will sit down to death, and everything will be empty.

Even Su Han in the previous life, when he reached the domination realm, he also felt that although his longevity had skyrocketed, he didn't know how much, but it was still not infinite.

And the things that have survived for so long and increased longevity, Su Han has seen a lot and owned a lot.

But those things are extremely precious, in the Star Field, in the Holy Domain, there are countless people competing for them.

Su Han once saw with his own eyes at an auction in the Holy Domain that there was a 'Holy Blue Flower' that could increase the longevity of a hundred years, and it was bought by a great power at a sky-high price of three trillion holy crystals.

Three trillion, what is this concept?

And what is the concept of Saint Crystal?

The spirit stones of the Longwu Continent are divided into lower-grade spirit stones, middle-grade spirit stones, high-grade spirit stones, and top-grade spirit stones.

And above the spirit stone, in the inferior star field, the spirit stone is not looked down upon at all, and the common currency there is the spirit crystal, and only those who are low in cultivation will still use the spirit stone.

The inferior star field uses spirit crystals, the medium star field uses immortal crystals, the upper star fields use divine crystals, and the sanctuary ...... Use the Holy Crystal!

Saint Crystal can be said to be the highest level of currency in the entire galaxy and starry sky.

If you don't treat it as a currency, this holy crystal will be brought to the Longwu Continent, and each one of them will be a shocking treasure.

It can be directly refined and absorbed, improved cultivation, can refine pills, can refine artifacts, and can also be used to set up arrays......

The usefulness of the Holy Crystal is really too much.

Three trillion holy crystals, if placed in normal times, I am afraid that more than 10,000 holy blue flowers can be bought, but at that auction, there were two heaven and earth powers that were about to reach the limit of longevity, and because the holy blue flowers were useful at that time, they were snatched up by many forces, causing them to find it, but they couldn't find it.

Therefore, there will be a sky-high price of three trillion.

It can also be seen that at the critical moment, how valuable the items that can increase longevity are!

And these blood crystals ......

In Su Han's opinion, even the lowest-level, comparable to the Dragon Vein Realm, can increase longevity!!

"If these blood crystals are sold in the Sanctuary, the price will ......."

Su Han's eyes were bright, and after a while, he smiled bitterly.

With his current cultivation, if he wants to step into the holy realm, I don't know how many years it will take.

Thinking of the scene at the auction at the beginning, when the two heaven and earth powerhouses were fighting for a holy blue flower, their faces were red and their ears were red, and even in a rage, they almost made a move, Su Han's expression was a little strange.

With a slight groan, a cold light flashed in Su Han's eyes, and he suddenly spoke: "Soul search!" ”

The palm of his hand pinched on this blood crystal, and the power of soul searching was directly unfolded!

"Boom!"

Almost at the moment when the power of soul searching unfolded, a shocking blood light suddenly bloomed from this blood crystal.

In Su Han's mind, many memories flashed quickly like flowing water.

In that memory, there is a world.

In the world, everything is blood-red, the ground is blood-red, the sky is blood-red, the sun is blood-red, and the moon is blood-red!

There is no black and white in heaven and earth, and no matter how the years pass, there is only one color, and that is blood red!

And in this world, Di Luo was born in a village, and with the passage of time, he gradually grew up, joined one force after another, and finally after three thousand five hundred years, he reached the cultivation of a one-star demon god, and just consolidated, he was sent here by the army of heavenly demons, and became one of the small leaders of this invasion.

At the end of this memory, a picture flashed.

That was when they were about to come to the Longwu Continent, standing outside the Longwu Star, turning into snowflakes, and when they fell, a figure suddenly appeared.

This figure is none other than Long Lie!

Long Lie watched this scene silently, not knowing what he was thinking, and finally cut open the blood-red passage alive, blocking the countless Heavenly Demon armies behind him.

And Di Luo, already at this time, entered the Dragon Martial Star, turned into snowflakes, and slowly fell.

Through memory, Su Han knew the cultivation level of these extraterritorial heavenly demons, demon disciples, demon people, demon spirits, demon stars, demon babies, demon gods, great demon gods, and demon lords.

There are a total of eight levels, which correspond to the cultivation realm of the Longwu Continent.

And in each level, it is divided into three stars, which are exactly the same as the early, middle, and late stages on the Longwu Continent.

And above the demon lord, Di Luo vaguely knew that there were some extremely powerful people, but what exactly it was called cultivation, Di Luo didn't know, just like the Dragon God Realm, who didn't know the realm beyond the starry sky.

"In the starry sky, there are a total of ten universes, the universe where the extraterritorial heavenly demons exist, is comparable to the galactic starry sky, the so-called demon lord is just a world, or rather, it is just the highest cultivation realm in a planet!"

Su Han muttered in his heart: "I just don't know if a strong man at the demon lord level has descended on the Longwu Continent." ”

He thought of the huge figures that roared incessantly when Long Lie slashed through the blood-colored passage.

They were also seated in a palanquin, but they were much larger than Dillo.

Di Luo's memory flickered too fast, and Su Han searched it in detail.

And as the search continued, Su Han's face became more and more gloomy.
