Han Leng stayed in the classics building for three days, because there were too many classics here, even if he found the type of books, he would not be able to read them in a while, because he was worried that the spiritual power in his body would disappear faster and faster, so he could only look for books as soon as possible to find a way to restrain the dissipation of spiritual power.

In just three days, Han Leng became famous again, and the title of a scholar began to circulate in the sect, saying that there was an inner disciple who soaked in the classic building all day long and looked through books, and never stopped for a moment, I am afraid that it was the longest reading time in the building since the founding of the sect, even if it was the classic administrator, he couldn't help but be impressed by him, and sometimes the classic administrator still thought very distortedly in his heart, this product would not be a book without a spirit stone, and he wanted to prostitute himself in this classic building.

After three days of sleepless frantic reading, Han Leng's whole person was sluggish, if it weren't for the spiritual power, I'm afraid he would have been tired and lying down, he is now listless, the dark circles under his eyes have also come out, and his unkempt appearance looks like a street begging.

He didn't know how many books he had read, and he didn't find a way to seal his spiritual power, but he made up for the history and knew some things that happened in the cultivation realm in the past, it was really a period of ups and downs, but Han Leng's mind didn't stay too long in that magnificent ancient time, he had to solve his own problems first, otherwise the realm would fall and find someone to reason with.

With trembling hands, he pulled out a thick ancient book from the shelf, the top of which was covered with a layer of fine ash, and it seemed that no one had taken a book from this shelf.

"The Formation Encyclopedia. Han Leng read the name on the book, and then looked through the book without much hope, what was recorded on it were some ordinary formations, and it was not written how the formation was arranged, but it simply explained the role of the formation.

Han Leng had actually come into contact with formations earlier, such as the Demon Slayer Array, as well as the Xuanling Sect's Sect Protector Array, these all belonged to the category of formations, and once the formations were arranged, they could exert amazing power, and some formations could even trap the monks of the Yudan Period, but they were all relatively advanced formations.

Han Leng didn't know anything about how to arrange the formation, the formation had a complete system, if it wasn't for the painstaking study of it, he wouldn't have made any achievements in the formation path at all, Han Leng was now even improving his cultivation was a difficult thing, and he had no time to study any more formations.

After reading the Spirit Gathering Array and the Gravity Array, Han Leng had lost interest in looking back, firstly, because he had consumed too much energy, and secondly, because he felt that he might have found the wrong direction, and if he changed another category, he might be able to find a way to control his spiritual power.

But just as he was about to put the book back, a flash of inspiration suddenly appeared in his head, and the ghost sent the god to turn the page back, and then he saw a formation called the Locking Spirit Array.

This formation can block the spiritual power in a certain space, so that it cannot be separated, usually this formation is used in the magic weapon or puppet that needs to store spiritual power, which can greatly increase the power of the magic weapon.

"This formation seems to be able to seal the spiritual power in my body..."Han Leng muttered to himself, his already dim eyes suddenly glowed with a glimmer of brilliance, he secretly wrote down the name of this formation, and went to the bookshelf on the other side to record the detailed pattern of the formation and walked over.

There are only two bookshelves for these formation atlases, and there is only one book on each bookshelf that supports the scene, it seems that the books that record the detailed formation are also relatively scarce in the cultivation realm, and his heart immediately cooled half, because the lock spirit array mentioned in the book just now is actually a relatively old formation, and he is very worried that there is no record in these books.

Han Leng simply tried his luck, he quickly read all these books, and the brilliance on his face suddenly dimmed again, there was really no formation diagram of the Locking Spirit Array, but there were still a few words about the introduction of the Locking Spirit Array.

The book reads: "Because this array is too complex, the requirements for the person who creates the magic weapon are extremely high, and the yield is very low, which makes the consumables for building the magic weapon increase, so this array was lost five hundred years ago." Puppets mostly use spirit stones to directly provide spiritual power, and grooves are also carved in the magic weapon to place the demon beast inner pill, so that the user can directly transmit spiritual power into the magic weapon, and the effect is better than using the lock spirit array..."

That's right, the depiction method of this Locking Spirit Array has been lost!

This cruel result almost didn't send Han Leng away, he just wanted to find a way to control the dissipation of spiritual power, was it so difficult?

In addition to being disheartened, he also took an inward look at the dantian, and found that those restless spiritual powers had obediently returned to the dantian, but the spiritual power that dissipated a few days ago also made his cultivation drop a lot, and it was estimated that he had wasted at least half a year's spiritual power.

He knew that this time the dissipation of spiritual power out of the body was just the beginning, and maybe there would be another time in the future, he had to find a solution as soon as possible, otherwise if he came two or three times, his realm would really fall.

Han Leng now only knew that the Locking Spirit Array had some use, but the formation diagram was lost, and he returned to Seeking Heart Peak in frustration, only to meet Song Lan and Lu Xun who came back from the mission.

Seeing that these two people were scarred, the blood had not completely dried up, and the smell of blood could be smelled from a long distance, Han Leng hurriedly walked over and asked, "Senior brother, what are you doing here?" Why are you so seriously injured, I have a few bottles of secret healing medicine here, you and Senior Sister can quickly apply it." After speaking, Han Leng took out the medicine bottle, which was all the healing medicine he had prepared in the Xuanling Sect, and the herbs used were all thousand-year-old herbs that he had matured by himself.

Song Lan took the medicine bottle and looked at it, shook his head lightly and said: "I have to go to the extremely cold ice room to freeze and stop the bleeding for this injury, the demonic power of that purple-eyed ape is peculiar, I have used many elixirs in the sect but can't stop the bleeding." ”

Song Lan's face was pale, and Lu Xun was already lying on the stone table, red blood kept pouring out of the wound on her back, staining her clothes red.

Han Leng opened the medicine bottle by himself and poured some into Lu Xun's back, as soon as these medicinal powders touched the blood, they worked instantly, only to see that the blood that was still flowing immediately coagulated, stronger than the cold and frozen ones, after stopping the bleeding, he only needed to regulate his own luck, and the wound would soon heal.

"Senior brother, what kind of medicine are you, how can it work so well, the bottle I bought with hundreds of spirit stones is not as good as your medicine!" Song Lan was taken aback when he saw this, he also quickly poured some medicinal powder on his hand, and then smeared his wound, and with a warm feeling hit, the bleeding wound instantly formed a bloody scab.

With such a miraculous medicine, what do you have to do in the Extreme Cold Ice Room, and it costs a lot of spirit stones to carry out freezing treatment, and you have to endure the torment of low temperatures.

Han Leng coughed dryly, and said in his heart, "The medicinal materials I use in this recipe are all thousand-year-old medicinal herbs, can that be bad? Any medicinal herb can be exchanged for a few high-level magic weapons, how can it be compared to those golden sore medicines that can be exchanged for some herbs casually.

However, although he thought so in his heart, he still said modestly: "These bottles of medicine were obtained from a cave when I didn't come to the sect, and I thought it was useful and kept them." ”

Song Lan showed a surprised expression, and then said with a wicked smile: "Why are you so lucky, can you tell Senior Brother where the cave is, and let Senior Brother try his luck too!"

"Uh... I've long forgotten which cave it is, so let's see how my sister is doing. Han Leng smiled awkwardly, and said in his heart that he would have to make up a new story in the future, otherwise he would always feel suspicious when he always talked about the good things he found in the cave, and he didn't want to talk about the healing medicine now, so he quickly diverted his attention.

Sure enough, as soon as Song Lan heard this, his heart suddenly became nervous, because Lu Xun had already fallen into a coma since he first came to Seeking Heart Peak.

Because Xuan Lingzi had also studied the Tao of Medicine in addition to his practice, Han Leng also got a little medical inheritance from his memory, although he couldn't be at the level of a divine doctor, but he could still do it by checking the severity of his injury.

Han Leng looked at Lu Xun, who was covered in blood, and then tapped a few acupuncture points on her body with his fingers, and finally said with a sigh of relief: "Senior sister is not very seriously injured, after stopping the bleeding, you can recover after a day of rest, how did you and senior sister provoke the fire-eyed ape? That is a famous demon beast on the Hundred Beasts Map, and even the monks at the peak of the foundation building period dare not easily make enemies with it." ”

This kind of powerful demon beast, as long as it is not violated territory, generally will not take the initiative to attack human monks, Han Leng speculated that the senior brother and sister probably broke into the territory of the fire-eyed ape this time because they were looking for something.

Song Lan shook his head and sighed, hesitated for a while before saying: "We are all for the Yang Yanlang of the Cuiyun Peak lineage, originally he and Senior Sister Lu Xun were going to become Taoist couples and double cultivate together, but Yang Yanlang didn't know why, saying that he had been poisoned by a strange poison that required five hundred years of medicinal silver needle grass to detoxify, and said that his life was not long, and he was afraid that after being with his junior sister, he would delay his junior sister's cultivation, so he dragged down the matter of becoming a Taoist couple." In the past few years, the junior sister has been looking for the silver needle grass, hoping to save Yang Yanlang, and this time she broke into the territory of the fire-eyed ape, also because she found a silver needle grass there. ”

"The last time we went, my junior sister couldn't control the fire-eyed ape because of the blue water pupil's backlash. Later, junior brother, you came to the Seeking Heart Peak, and also helped the junior sister heal the soul injury, so we went to the territory of the fire-eyed ape again, this time the junior sister used the blue water pupil to control the fire-eyed ape for a long time, and when I picked the silver needle grass, the fire-eyed ape was out of the illusion, so the two of us were so embarrassed..."

"I see... Senior Sister's Daoist has a strange poison in his body, and he needs to use more than five hundred years of silver needle grass..."Han Leng pondered it carefully, and combined with the memory inheritance left to him by Xuan Lingzi's predecessors, the more he thought about it, the more he felt that it made sense.

First of all, in the current cultivation realm, medicinal herbs have become very rare, and the newly cultivated medicinal materials in the Damen Sect are only a few decades of medicinal properties, and the most precious ones are three hundred years old, and the five hundred years of medicinal materials have been mined almost long ago, and it is difficult to find them in the outside world.

Secondly, Han Leng specially found a record about the silver needle grass, this herb is generally not used to make antidotes, because the silver needle grass is originally highly poisonous, if you use more than 20 years of silver needle grass, you can prepare a simple antidote, but the silver needle grass with a medicinal nature of five hundred years, that is a highly poisonous thing, the monk in the foundation building period is lightly stabbed, the whole body will be paralyzed, if you can't quickly use spiritual power to expel the toxin out of the body, you will die in less than ten breaths.

Until now, even a person with superb medical skills did not dare to easily make the silver needle grass into an antidote, and Han Leng was now a little skeptical that the person who prescribed Yang Yanlang was a quack doctor.

"Senior brother, can you let me take a look at the Silver Needle Grass?" Han Leng said.

Song Lan nodded, and then took out a slender plant from the Qiankun bag, which was the so-called silver needle grass.

Its leaves are rolled together, and the whole body is still green, but the tips of the leaves are slightly blackened and very sharp, and it seems to easily pierce the animal's fur.

Han Leng glanced at it and sighed lightly: "This silver needle grass is full of color, and it seems that it only has medicinal properties for twenty years at most, and only those that have completely lost their moisture and are gray all over are more than a hundred years old." ”

Han Leng knew how to distinguish the year of the medicinal herb, so he could see at a glance that this herb did not have the medicinal properties of a hundred years.

Song Lan was stunned when he heard this, his eyes first flashed with excitement, and then turned into a disappointed look, he shook his head and said, "My senior sister and I were so seriously injured, and we only got back such a medicinal herb, alas... It seems that Yang Yanlang's life is too bad. ”

Lu Xun's body lying on the stone table also trembled slightly, and tears flowed from the corners of her eyes, she couldn't believe this fact, the silver needle grass that she desperately snatched from the fire eye ape turned out to be just a few decades of medicinal properties, how could this be good?
