Cheng Ling opened his eyes and found that Liu Qingyan and the others were still continuing to comprehend the patterns on the wall, so he didn't bother, left a jade slip of sound transmission, and quietly left the library pavilion.

I found a secret place and began to enlighten myself. The Heavenly Demon Sacrifice Technique is divided into three layers, the first layer, which stimulates the true element in the body and burns the essence and blood for a quarter of an hour, increasing its own combat power by one and a half times.

The second layer lasts for two sticks of incense and doubles its combat power, and the third layer lasts for half an hour and quadruples its combat power.

It can be said that the Heavenly Demon Sacrifice Technique is a very powerful secret method. The only drawback is that the consumption of true yuan and essence blood is too large. Every time you use it, if you can't recover it in a short period of time, it will cause a large amount of true essence and essence blood to drain, and in serious cases, it will even damage the foundation of the cultivation path.

"What I have in my body is the diluted sword element of the true element, once it is burned, the power may be even more violent, I don't know if the body can hold on. As for the recovered treasures, the gourd Sword Yuan Pill that I got in the Sword Shrine Secret Realm before should be able to support it for a while. ”

"As for the recovery of essence and blood in the body, we have to find a way to find other treasures!" "Searching the memory in the brain, there are three main treasures of heaven and earth to restore essence and blood, one is essence ginseng, this kind of ginseng grows in the mountains where the aura of heaven and earth is very strong, and it is not difficult to find.

It is a pity that Jing Yuan ginseng can only play an effective role in restoring essence and blood only in a certain year, and Jing Yuan ginseng within 300 years is only suitable for alchemy and strengthening the body, and only more than 500 years can help restore essence and blood.

The second type is the Blood Demon Flower, which only grows in places full of essence and blood, and it must also have sufficient demonic energy. It has a lot of effects, as long as it is bred, no matter how many years the Blood Demon Flower is, it is the best medicine to replenish the essence blood.

However, this flower has a drawback, it contains too much demonic energy, and it is easy to be contaminated by demonic qi while replenishing essence and blood, resulting in delirium, and in serious cases, it will fall into the devil's path. Only when one's own mind is strong, replenishing the essence and blood while refining the demonic qi in it, can safety be ensured.

The last one is the pill, which is called the Blood Essence Pill. It can replenish a large amount of essence blood in a short period of time, but the essence blood pill is a seven-grade pill, and it cannot be refined with Cheng Ling's current alchemy grade.

After thinking about it for a long time, he couldn't solve the problem of sperm and blood loss for a while, so he had to give up. He muttered, "That's it, this secret method comes from the fifth layer of the Canghai Dragon Palace Library Pavilion, presumably there must be people in the sect who cultivate, maybe these treasures can be found in their treasury!"

"Right now, first comprehend the secret method, and at least cultivate to the first level, so that you can increase your combat power. On this trip to the islands, you will definitely encounter unknowable dangers, and only by improving your strength as soon as possible can you get out of the way. ”

He had a lingering fear for the islands, and it took a lot of effort to escape with the help of Yan Hu. Yanhu is a demon general, and the corresponding cultivation realm is the merger period, with its cultivation, it is very difficult to leave the formation, and if a few of them want to retreat with their whole body, their strength must be improved again.

In front of them, Liu Qingyan and Jian Yinghao and others are still comprehending the patterns on the fifth layer, with their qualifications and understanding, they will definitely be able to gain something, and their combat power can be improved again, and they will have a greater grasp of rescuing Bai Suzhen and Hai Gonggong with the strength of everyone.

After thinking about it for a long time, put it aside for the time being, and wholeheartedly comprehend the secret of the Heavenly Demon's sacrifice!

Time passed, and soon three days passed, and Cheng Ling had not received news from Liu Qingyan and others, presumably continuing to comprehend the murals. The Heavenly Demon Sacrifice Technique has made some progress in comprehending it, and it is already the beginning of reaching the first level.

Ten days later, the first level of the Heavenly Demon Sacrifice Technique was completed. Cheng Ling took a long breath and took out a True Yuan Fruit and Yi Tendon Refining Body Pill, ready to test the power of the secret method. There is no corresponding pill to replenish the essence and blood, so it can only be replaced by the Yijin Tempering Pill first.

Silently reciting the secret method in his heart, his right hand is connected to a number of tricks, and the Heavenly Demon is activated. The momentum of the whole person skyrocketed instantly, his eyes turned blood-red, and the powerful sword momentum soared into the sky, all around

The air seemed to be cut and cracked.

With a sword in his right hand, he struck it out, and the mountain wall was bombarded and burst open, and the flying rocks turned into dust.

"This sword, without fusing sword intent and sword momentum, only used one percent of the strength. The power has reached twice as much as usual, and the increase of the sword yuan is really strong. ”

The sword yuan and essence blood that stopped burning in an instant, after a while, there was a feeling of weakness in the body, and he hurriedly swallowed the Yi Jin Refining Body Pill, holding the True Yuan Fruit in his hand to recover the loss.

After a stick of incense, the true yuan was recovered, a little thinner than before, and it had little impact. However, the essence blood is missing one percent, and the medicinal power of Yi Tendon Refining Body Pill only restores the strength of the body, but it cannot make up for the consumption of essence and blood, but fortunately, it only loses one percent, and it can be recovered in just a few days.

"It seems that we still have to find a way to get the treasure of restoring essence and blood! Ten days have passed, and I don't know how well the Sword Brothers and their comprehension have been. ”

As he was hanging, the sound transmission jade Jian vibrated and took it out and listened to it, it turned out that Jian Yinghao and the others had all completed their enlightenment, and asked him where he was? Cheng Ling replied, and made an appointment for everyone to gather on the first floor of the library pavilion, and then set off.

Back in the library pavilion, Jian Yinghao and the others were already waiting in front of the door.

Cheng Ling smiled and asked, "What do you have gained?"

Sword Hero laughed and said, "The fifth layer is good, I have obtained a heaven-level top-notch sword technique, and I have gained a lot!"

Liu Qingyan said: "I'm not bad either, get a spell!"

"Boss, I also got a sword technique, but unfortunately it's not as strong as Brother Sword, it's just a heaven-level high-level. ”

"Brother Ling, I have obtained a heaven-level high-level body method, and my life-saving ability has been greatly improved. ”

"Master, I got a sword technique, it is a second-grade sword skill, it can only be very difficult, and I haven't understood it thoroughly!"

"Sect Master, I got a fist technique!"

"I also got a body method, which is not bad!"

The people told them all about what they had learned.

Cheng Lingxi said: "It seems that everyone has gained, not bad! It's a pity that the pattern on the wall can't be taken away, otherwise if you visit it a few more times, you may be able to get more." ”

Jian Yinghao smiled: "Brother Cheng, you left the earliest, you must have a greater opportunity, and you haven't told me what to wait for?"

Cheng Ling smiled and said, "I got a secret method to increase combat power, and I gained a lot!"

Everyone exclaimed, and they all showed envy, the secret method! That is not easy to obtain, Cheng Ling's opportunity is really good. It's just that everyone has their own secrets, and this kind of inheritance will not be easily passed on if it is not voluntary!

It's not that Cheng Ling is unwilling to teach them the Heavenly Demon Sacrifice Technique, it's just that although this secret method is powerful, it requires extremely high conditions, and without pure true yuan and abundant essence blood, it is difficult to cultivate successfully, not to mention the supplementary medicine, it is beneficial and harmless to barely cultivate.

He said, "Now that we're done exploring the Library, let's go look elsewhere!"

The crowd agreed, as he continued to explore.

It was still Cheng Ling who took the lead and continued to search for the place where the treasure was hidden. Circumventing the mountains and coming to a secluded valley, Cheng Ling noticed something unusual.

At the entrance of the valley, it seems that there is a formation guarding it, and it is impossible to see the reality inside. He turned around and told everyone about the situation, then sat down cross-legged and deduced the formation nodes.

Three days later, basically figuring out the direction of the formation, he said: "There is a defensive formation in front of me, if you want to break it all, it will take a long time, I will open a passage, and everyone will enter in turn." ”

Everyone nodded in agreement. He began to refine the Formation Breaking Banner. It didn't take long for the array flag to be refined, Cheng Ling set the array flag in different directions, connected the dots with both hands several times, and the four array flags formed a square space, and the dazzling light flashed on the array flag, soaring into the sky for a long time.

After a moment, the eye

The front formation slowly opened.

Cheng Ling said: "Everyone enter quickly, the opening time of the passage is only ten breaths." ”

When everyone heard this, they rushed inside.

Ten breaths of time passed in a flash, and the formation was closed again, but fortunately, everyone had entered the valley.

Cheng Ling looked at the valley, and inside was a space of a hundred zhang square, the size of a football field. Directly opposite a mountain wall protruded, and on the lower side of the mountain wall, two huge stone doors were tightly closed, and several candlesticks were built in front of the stone gates.

Jian Yinghao said: "Brother Cheng, this place looks like the treasury of the Canghai Dragon Palace!"

Cheng Ling nodded in agreement and said, "I'll see how the stone gate is opened first, and whether there are any blocking mechanisms." ”

With that, he stepped forward and took a closer look. After a while, he turned his head and said: "There are no traces of formations and bans, the external formation should be to prevent outsiders from breaking in, and the stone gate here is very ordinary." Brother Sword, take a hand and open it!"

Jian Yinghao stepped forward, and the two of them worked together to push the stone gate outward.

"Click!

A dull voice came out, and the stone door slowly opened. Cheng Ling picked up a torch from the candlestick, pointed his finger, and the torch burned, and entered the stone gate first.

Everyone behind him also picked up a torch from the candlestick and followed Cheng Ling in.

After entering the stone gate, there is a long staircase. The staircase goes down and looks pitch black, I don't know how long it is.

Cheng Ling led everyone down the stairs and walked about a stick of incense before reaching the end of the stairs. In front of you is a hexagonal hall with a portal on each edge of the hexagon. The portal is tightly closed, and it also has the effect of shielding the divine sense, so that you can't see what is inside.

He walked over to the first portal on the left hand side and tapped his hand. The portal stood still, with little effect. Secretly shocked in his heart, with his own physical strength, this shot was not a thousand catties, and there was no movement.

It seems that these portals are not simple, what mechanism should be used to open them, and the use of brute force is never the right means.

He looked around the hall. After turning around twice, I found that there was a palace lamp next to each portal, which was carved into a dragon shape, and the lamp oil inside had long been exhausted, and only the decorative role remained. But the more he looked, the more he felt that the palace lamp was strange.

Thinking of the mechanism settings I saw in the TV series before, my eyes lit up, and I took two steps forward and grabbed the bottom step of the palace lamp. Rotate to the left, not moving! Rotate to the right, and there is still nothing abnormal!

It's a little confusing now, is it all a lie in the TV series, this palace lamp is just a lamp at all, and has no other role.

Everyone stood behind him, all watching quietly, they didn't dare to do it easily. But Bai Yiyi looked at Cheng Ling, and saw that he just kept touching the palace lamp, so he couldn't help it, and stepped forward and said: "Brother Ling, if you like this palace lamp, you will take it away later, why do you always touch it?"

After speaking, he stretched out his right hand and grabbed the palace lamp on the wall, wanting to break it off. Who knew that when she broke it, the palace lamp tilted, making a "click" sound, and the door on the side was opened!

"Oh my day, this can be too!"

Cheng Ling was speechless, looked at Bai Yiyi and said: "Yiyi, you are really a genius, I only know how to rotate left and right, I can't imagine that you can only open the door downward, it's really amazing!"

Bai Yiyi was stunned for a moment, reacted in an instant, smiled without any image, and said: "This girl is amazing! Things that even you can't think of have been thought of by me, wahahaha!"

Jian Yinghao was full of black lines, he naturally knew that Bai Yiyi was a blind cat who had met a dead mouse, with her arrogant temperament, how could she bother to think about the mystery of the palace lamp.

scolded and said, "It's all nonsense, and there is no image of a girl at all." Brother Cheng, don't pay attention to her, let's go and have a look first!"
