Regarding the Immortal Soul Grass, Lin Feng learned all the information about it from Ye Ming before, and he only knew that it was an extremely rare Nine-level spiritual medicine that could be used to refine the Immortal Soul Pill and its basic appearance characteristics.

However, in the memory of the Blood Demon Lord, there is extremely detailed information about the Immortal Soul Grass, because even in the era before the catastrophe, this kind of spiritual medicine only exists in legends and is used to refine the Immortal Soul Pill. It is only one of the functions of this kind of spiritual medicine, and there are many magical functions in the rest. However, Lin Feng only cares about the Immortal Soul Pill, and it is better not to mention the others.

The growth conditions of the Immortal Soul Grass are very special. It requires the most important factor, that is... the Soul of the Immortal!

This is the name of "Immortal Soul Grass".

Immortals can take the initiative to warm up the plants with their own immortal soul energy, day after day after year. After a long period of time, even an ordinary weed will undergo incredible mutations after constantly absorbing the immortal soul energy, and eventually grow into a top-level spiritual medicine, which is the "Immortal Soul Grass". It is simple, but it is actually an extremely long process, and it may not be smooth sailing. If there is a slight mistake during the period, you will lose all your efforts. Even if you don't make any mistakes, it will take more than ten thousand years to raise a mature immortal soul grass.

In the memory of the Blood Demon Lord, the immortal Yueyun once cultivated a fairy soul grass, but accidentally failed for eight thousand years.

In addition to the active cultivation of immortals, there is another situation where the immortal soul grass can naturally be generated. The immortal soul grass generated in this situation also requires a necessary environment, that is, the place where the immortals fall!

After the immortal falls, the remaining immortal soul energy after his death may naturally grow the immortal soul grass. However, the probability of growing mature immortal soul grass in this case is very low, at least it is much lower than that of the careful cultivation of living immortals.

And how powerful an immortal is, how could it fall easily? The "wild" immortal soul grass is naturally rare in ten thousand years. Even so in the fairy world, let alone in the cultivation world. Generally speaking, it is impossible for the immortal soul grass to appear in the cultivation world, unless it is passed down from the immortal world.

However, now, in the Yueyun Realm, there is a very special situation, that is, the catastrophe change 20,000 years ago, and the battle of immortals in this guide world!!

In that battle, in the memory of the Blood Demon Lord, it was confirmed that the Immortal Yueyun died on the spot. After he fled from the battlefield, there was a fierce battle where the connection and the boundary were broken. There was also a very high possibility that other immortals would fall.

In other words, in this remnant immortal world, there were at least one, and even many immortals, and it is very likely that they would have fallen here! And 20,000 years have passed, and it is entirely possible to grow mature immortal soul grass!

This news is even more important to Lin Feng than any other spoils he got, so now after cleaning up and adjusting his best condition, the first thing he wants to do is to look for the Immortal Soul Grass.

With the memory of the Blood Demon Lord, he is probably more familiar with the remnant immortal world than anyone else. He already knows where he is at this time, not far from the catastrophe battlefield back then, and should be in this remnant realm!

This residual area is the central area that led to the world back then, so the spiritual energy of the heaven and earth here is so strong that it gave birth to powerful monsters such as the giant hill beast he had seen when he first came.

...

After coming out of the cave, Lin Feng followed the memory of the Blood Demon Lord and sneaked towards the back of the mountain.

The reason why he said "slide" is because it is too dangerous here. Even if he has fragments of the secret treasure of the Creation Realm, he doesn't have to worry about the special environment. Even if his strength has improved a lot, he dare not take it lightly at all. If it is too silly, such as flying directly, it will cause attacks from level 7 or even stronger monsters, it will be troublesome.

Lin Feng has an invisible cloak, and now he has an "empty hidden technique". As long as he is careful, the safety factor is still very high. Even if he encounters a level seven monster, he can avoid it safely. Although it is not fast, he is very smoothly heading towards his destination.

However, after walking for about a hundred miles, Lin Feng found that the terrain environment he saw was almost completely different from the one in the memory of the Blood Demon Lord. It was not that the memory of the Blood Demon Lord was wrong, but that the environment had changed. This was no longer the beautiful place with clear mountains, clear waters and fairy charms in the memory of the Blood Demon Lord, but it turned into... a piece of ruins.

At first glance, until the end of the sight, there is a desolate and desolate scene. The number of animals and plants is becoming more and more rare. Almost every mountain peak is incomplete. There are thousands of ravines and ravines on the earth, and the traces of battle caused 20,000 years ago are still clearly visible until now.

Standing in front of a bottomless gully, Lin Feng couldn't help but feel a little confused. He seemed to have seen a powerful monk waved his hand and cut a gully on the ground in the battle 20,000 years ago. If he was asked to come, even if he had to attack the ground with all his strength for a day and a night, he would probably not be able to achieve such destruction.

Using the "Splash Technique" to cross this gully, Lin Feng continued to move forward. While trying to compare with the terrain in the memory of the Blood Demon Lord based on the surrounding incomplete environment to confirm the direction, he carefully paid attention to the movements around him. The environment here has become desolate and is easier to be alert than before, but he still cannot be careless, because he already felt that the spiritual energy of the heaven and earth here is also richer than elsewhere. The monsters bred in this environment must be more powerful and must not be neglected.

What disappointed Lin Feng was that he had not picked up any treasure after walking for so long. It seemed that the battlefield had been cleaned up. I don’t know if it was cleaned up by the people who won the catastrophe in that year, or by the monks who came here later in life.

...

Just thousands of miles ahead of Lin Feng's direction, there is a huge valley with an area of ​​hundreds of miles. On both sides are mountains that stretch out and cannot see the end. It looks like a complete mountain range was destroyed from it, forming this valley.

In the cultivation world of Yueyun Continent, only monks above the fusion stage will know that it is said that immortals once fell here, so this place was called the Burial Immortal Valley by later generations.

Legend has it that there are countless treasures in this Immortal Burial Valley, and even immortal heritage. Since ancient times, countless powerful people have come here to search for treasures, but very few can go back alive. As for the specific situation here, it has always been a secret that few people know.

Although we know that this place is very dangerous, since ancient times, the monks who come here to explore have never stopped. All those who have the ability to come to this Immortal Burial Valley are powerful monks.

At this moment, in this Immortal Burial Valley, there was a group of monks, a group of four, all of whom were gray-haired old men, three men and one woman, who were moving forward cautiously.

"Be careful, the front is the area of ​​the gale wind."

The old man in purple robe walked in front looked solemn and whispered a reminder while walking.

The three people behind him looked at each other without saying anything, but their expressions became more cautious. The old woman in white took out a fist-sized blue crystal bead from the object ring. As the Zhenyuan activated her, a dark blue defense cover several meters in size enveloped the four of them.

When the blue light shield was released, everyone seemed to feel a little relieved. Just as they were about to move forward, a cold wind suddenly came to their faces. The four people with the lowest cultivation level were all shaking, and then their faces changed at the same time.

"Not good!! The area of ​​Gangfeng has expanded! Be careful to defend!"

The old man in purple robe shrank his pupils and instantly reacted, and a low shout came out of his mouth. Almost as he spoke, a strange phenomenon suddenly appeared around his originally calm surroundings.

“Woo woo woo woo…”

A strange sound of wind blew out of thin air, even giving people the illusion of howling ghosts and gods. The air suddenly appeared in the surrounding air, with strong blue wind rising flat, sand and stones flying, cracking soil and cutting wood, and countless wind blades of different sizes swept wildly, covering a radius of dozens of miles.

These wind blades were not targeted by the four people on the ground, but they were too dense. In just a few breaths, the four people were attacked by dozens of wind blades. Although most of them were broken by the four people using magic in front of them, several of them still fell on the blue light shield above their heads, which caused a buzzing sound every time. The crystal magic weapon in the old woman's hand trembled, which made her look shocked.

The old man in purple was also gloomy at first, because the power of this gale was stronger than when he came last a hundred years ago, and the scope was expanded. In this way, it would be more troublesome to pass through this area than expected. However, they naturally could not retreat because of this unexpected difficulty. The four of them stopped in place for a moment and adapted to the rhythm of defense. The old man in purple spoke, "Continue to move forward, one person in one direction, don't be confused."

The other three nodded slightly, while constantly attacking the wind blade, and began to move forward slowly.

But at their speed, I'm afraid I don't know how long it will take to pass through this gale wind area...

...

Just as the four powerful monks here walked carefully and moved forward with the gale wind, a figure was also moving forward in the gale wind several miles away. However, this person's situation could be described as "strolling in the garden".

This person was naturally Lin Feng. The wind was sweeping around him, but within ten meters of his body, it was calm. When the wind blades approached him, they were disguised by an invisible force and flew elsewhere.

"Huh?" As he was walking forward, Lin Feng suddenly stopped and turned to look to the left, saying in surprise, "Is there anyone else here?"
