Lei Luo and Bai Muling walked about halfway up the mountain, and they didn't encounter any other people stopping them along the way, but walked for half an hour without any danger.

Since they didn't know their ranking, the two of them could only hurry up, after all, there were only a thousand ranks, and there were 10,000 people in the valley at that time, which was a one-tenth chance.

"Stop!" As he walked forward, Lei Luo smelled something unusual.

"The smell, it seems," he muttered.

Then Lei Luo sniffed in the air, and then quickly moved forward after identifying a direction, Bai Muling naturally did not have the slightest opinion on this, and hurriedly followed.

Lei Luo walked around the forest following the smell, observing around as he walked, and then continued to move forward cautiously.

When he came to the location of a pit the size of three or five feet, he glanced around, then sniffed in the air with his nose, and then smiled knowingly, knowing that he had arrived at the place.

I saw that in the pit in front of me, there were several corpses of young people lying down, which seemed to illustrate the cruelty of the road to seek immortals, and next to the corpse, there was actually a bright red grass growing.

"This fragrance, this color, this shape, it should be the Heart Nourishing Grass, this is the main flavor medicinal material for refining Guben Dan and other pills," Lei Luo looked at this small grass and said with a slight surprise.

"Is there anything special about this little grass?" Bai Mu Ling asked after seeing Lei Luo's expression.

In her impression, this junior brother of hers is not a person who will be happy when he sees a small grass, on the contrary, such a small grass still grows among so many corpses, which must be a little strange.

At that moment, Lei Luo explained to Bai Muling the effect of the Heart Nourishing Herb and refining the Guben Dan, it turned out that this Guben Dan was a kind of Guben Peiyuan pill that monks below the foundation building period could take, and the effect was to refine the spiritual power in the body, and at the same time it could increase the success rate of foundation building.

Moreover, even if the monk cultivates the basic exercises to the tenth-level perfection realm of Qi cultivation, as long as he takes one more of these Gu Ben Pills, then the spiritual power in his body can be refined a little more, so that the probability of success in foundation building can increase a little bit, about half to one percent.

As for the other pills that can be refined by this Heart Nourishing Herb, the effect on Qi cultivation is not as great as that of the Guben Pill, so Lei Luo did not elaborate on it in order to save time.

"Did you learn these from the books of Lan Jushi's Herb Pill?" Bai Muling didn't expect Lei Luo to be proficient in alchemy, and he was slightly surprised.

At the beginning, he made the decision to let Lei Luo learn to collect herbs and alchemy, but he didn't expect that the other party would work so hard, and before he knew it, he had reached the realm where even the pills of Qi cultivators could be refined.

"The way of cultivating immortals is not just about retreat and penance, sometimes it is necessary to learn a little more to expand your horizons!"

As he spoke, Lei Luo walked to the edge of the pit, then crouched down and looked at it carefully.

"Since this heart cultivation grass is so precious, why can it still grow in this mountain, won't the people in front of it take it away?" Bai Mu Ling asked.

"The age of this grass is about seven or eight years, and it hasn't grown in the last trial, so this time it's just our luck," Lei Luo explained after glancing at the size of the herb.

After explaining, he grabbed a handful of soil with one hand, and then sprinkled it towards the position of the heart cultivation grass, and after seeing that there was no movement in the herb and the surroundings, he continued to scatter another handful, and then carefully observed.

"What are you doing, why don't you go and collect medicine?" Bai Mu Ling said with a puzzled expression.

She was very strange about Lei Luo's behavior, why didn't she go to collect medicine and do some strange things, like a fool, but in her heart she knew that Lei Luo didn't do meaningless things.

"Hmph, these two corpses died here because they went to collect medicine, I wouldn't be such a fool," Lei Luo replied with a sneer.

His hand kept moving, and he kept sprinkling the dirt on it, and in this way, the soil also spelled the sound of "sprinkling", and then gradually submerged the heart-nourishing grass.

Suddenly, a black shadow suddenly appeared from the two corpses, and this black shadow flew straight towards Lei Luo, extremely fast, and after looking at it, there was a trace of turquoise in this black shadow, which was actually a small turquoise snake one foot long.

"It's you who are waiting!" Lei Luo didn't panic at all when he saw the green snake rushing towards him, and after holding the red light saber in his hand, he directly raised his hand with a sword, and after a sword blow, he split the green snake into two parts.

Looking at the corpses of the two little snakes that were still struggling violently, Lei Luo calmly stepped forward and gave it a kick, completely crushing the snake's body into a puddle of flesh.

"How did you know that there would be a little snake hiding, and how did you force it out?" Bai Muling couldn't help but ask when he saw Lei Luo's action of killing the green snake in one go, as if he had expected it.

This feeling was as if the other party knew that the little snake was in ambush when they approached here, so she thought a little more highly of Lei Luo's methods.

"There is a hint of toxicity in the Heart Cultivation Grass, and when it grows, it exudes a strange medicinal fragrance, which naturally attracts the surrounding poisons to get closer," Lei Lu explained.

And he was not idle in his movements, this time he went directly to the pit and turned the herb up with the surrounding soil, because the poison had been killed, so there was no other danger.

"I sprinkle dirt in this pit, it will make the poison think that I am going to fill this hole, but any animal with a little instinct will stop me from moving, or simply leave the hole, this green snake is really a trick!"

Lei Luo explained what he had just done, and then took out a special jade box from the storage bag, put the herb in its entirety, and carefully kept it.

"It seems that with my junior brother, I can still learn a lot of things," Bai Muling teased, and then watched Lei Luo come out of the pit.

"The way of cultivating immortals, we are still in the initial stage, you just need to know some heaven and earth spiritual objects, and there are guardian beasts next to the cherished medicinal materials," Lei Luo glanced back at the pit, and then said.

He had also heard these from some folklore, but next to the spiritual material spirit treasure against the sky, there must be some powerful demon beasts guarding it, which should be the same reason.

"Then it seems that we will all have to fight with the beast in the future," Bai Muling chuckled lightly after hearing Lei Luo's words.

"If it is really a precious heaven and earth treasure, the level of the surrounding demon beasts may be very high, I think that the IQ of those high-level demon beasts is actually no less than that of humans, so I really regard the demon beasts as beasts, but I will suffer!" This time Lei Luo solemnly reminded.

For demon beasts, especially high-level demon beasts, he is very longing and curious, because he has heard from some people that the intelligence of high-level demon beasts will be as smart as humans.

Moreover, high-level demon beasts, when they cultivate to a certain strength, they can even turn into human form, spit out human words, maybe after turning into human form, these demon beasts can also control the flow of magic weapons and do the same thing as human monks.

However, Dongyue Kingdom, including the surrounding areas, has not heard of any rumors of demon beasts that have become humans, not even the demon beasts of the Jindan period, let alone the realm of higher realms.

After collecting the herbs, Lei Luo and Bai Mu Ling chatted about some rumors about demon beasts as they walked, but most of the time he was talking about Bai Mu Ling and listened to it.

Due to the delay in collecting medicine for a while, they couldn't help but speed up the pace and move forward, after all, the number of places is limited, I am afraid that some people will rush straight away, and now they have reached the top of the mountain.

Along the way, they didn't encounter any herbs, nor did they encounter any so-called natural treasures, and some only had bloody corpses.

When Lei Luo saw the corpse on the ground, he suddenly stopped, and then walked to the corpse and observed silently, just in Bai Muling's doubts, he looked at several corpses in a row.

When Bai Muling was about to ask what was on Lei Luo's corpse, he raised his hand and signaled, and then quickly moved forward in one direction.

Seeing this, Bai Muling hurriedly followed, but she was a little curious in her heart, why Lei Luo's face became solemn after looking at a few corpses.
