The iron sheet is in a triangular shape, only the size of a palm, light as nothing, but very hard, not belonging to any kind of material that Li Yi knows, and what is even more strange is that the iron sheet seems to be engraved with a few lines of small characters, but it is covered by some strange filth, no matter how Li Yi wipes it, it can't be wiped clean.

It seemed that the filth did not grow on the surface of the iron sheet, but on the inside, like a cloud, enveloping the few lines of small words.

"I don't know what to write?" Li Yi didn't give up and wiped it desperately.

Suddenly, there was a pain in the finger, and the fingertip was cut by one of the edges and corners of the iron piece, and blood flowed.

One drop of blood, falling on top of the piece of iron, disappeared in the blink of an eye.

The next moment, the iron piece flashed with a burst of cyan light, and an ancient whisper sounded in his ears, the voice was extremely heavy, like substance, every note hit Li Yi's ears heavily and engraved in his mind.

"Ah------h

Li Yi hugged his head, feeling an incomparable pain, and his head was almost bursting.

Suddenly, a burst of golden light lit up in his mind, as if someone was holding a sword and carving words in Li Yi's mind.

He was no longer in pain, but his whole body became stiff and numb, his blood stopped flowing, and his heart stopped.

After what seemed to be 10,000 years, the golden light finally faded, and Li Yi's body regained consciousness, but he didn't move, because an ancient text was engraved in his mind.

"Demon Refining Technique"!

"The First Miraculous Achievement of Antiquity...... Cultivating this exercise, you can refine the ten thousand demons in the world, refine their essence and blood, seize their supernatural powers, and combine the strengths of ten thousand demons in one, which is enough to reverse the universe and live forever!"

People cultivate mana, demons practice supernatural powers, some powerful demon beasts, born with a variety of incomparably strong supernatural powers, with a gesture, there is the power to destroy the world.

When the Terran monks confronted the demon clan, they were always at a disadvantage, and they often needed to be in groups to be able to kill a demon beast, just because the demon clan had magical powers.

Li Yi was dumbfounded, and it took a long time before he came back to his senses, and pinched his thigh hard, convinced that he was not dreaming.

"The World...... How can there be such exercises?"

Just as he was shocked, suddenly there was a sound of hurried footsteps above the cave.

Li Yi hid the iron piece in his arms, jumped up, borrowed strength on the stone wall of the cave one after another, jumped on the ground, and saw that not far away, a disciple came over, his face was covered with a white cloth, his arms were straightened, and he was carrying a wooden barrel, which was tightly covered, as if the wooden barrel contained a fierce beast and poisonous snake, for fear of running out.

Li Yi lowered his head, just wanting to leave.

"Hey, aren't you afraid of stink?" the man said in surprise when he saw that he didn't cover his mouth and nose.

Li Yi knew that this person mistakenly thought that he was also here to throw away discarded goods, and he didn't want to be noticed that something was abnormal, so he responded: "It's good to get used to it, what do you have in this bucket?"

"Alas, bad luck, Senior Brother Zhang in the alchemy room, a few days ago, he was whimsical, and he got some snake demon blood out of nowhere, and wanted to refine it and use it for alchemy, hey, you said that the snake was very poisonous, and a drop of blood could poison ten people, is it so easy to refine? The man grumbled.

After Li Yi listened, his heart moved.

The snake is a kind of winged, able to fly monster beast, extremely poisonous, terrifying, although not the kind of powerful demon beast with supernatural powers, but in the ordinary demon beast, it is one of the best existence.

"In the "Demon Refining Technique", it is said that you can refine all the demons in the world, so can you also refine the blood of this snake demon?" Li Yi thought for a while, his eyes flickered, and he suddenly said: "Senior brother, I'm used to the smell here anyway, why don't you let me help you deal with it." ”

The man looked overjoyed and said, "Really, that's great, but you have to stay away, and be careful not to let this poisonous blood get on you, or the consequences will be terrible!"

As he spoke, he handed the barrel to Li Yi, thanked him, and walked quickly, as if he was afraid that he would regret it.

Li Yi didn't go far, he left the valley with his heels, came to a secluded forest nearby, took a deep breath, opened the lid of the barrel, only smelled a fishy smell coming to his nose, his mind was dizzy for a while, and he hurriedly retreated a few zhang away, breathing, and felt a lot better.

"The blood toxicity of this snake demon is so strong, it will be poisoned even if you smell it, and I don't know if the Demon Refining Technique can be refined?" Li Yi really had no bottom in his heart.

"But you have to give it a try!" In the end, he still made up his mind and began to comprehend the mental method of "Demon Refining Technique".

His comprehension is not bad, just because he is not valued by the family, it is difficult to make progress in his cultivation, but the "Demon Refining Technique" is extremely profound, and everything he thinks and thinks is a different way, and he can't be guessed by common sense, which is very different from what he usually learns.

After two hours of enlightenment, I was still confused, like reading a book from heaven.

Finally, his perseverance is outstanding, the more he doesn't understand, the more he refuses to give up, he stumbled for a long time, and suddenly had an idea: "This exercise treats the orthodox way of persuasion as chaff, which can be called a great rebellion, and it must not be understood with normal thinking, it is better to put aside prejudices first, maybe it will be different!"

Thinking about it like this, and looking at it again, it didn't take long for me to have some eyebrows.

Although these Xu Meimu are extremely ridiculous crooked and heretical in the eyes of a normal person, Li Yi didn't care at all, followed the vine and touched the melon, kept groping, and saw that in the early morning of the next day, he breathed a sigh of relief, and finally had a little bottom in his heart.

It turns out that this exercise is full of loopholes at first glance, but if you find the right context and comprehend it completely, all the loopholes will be closed at once and become seamless, which is really a miraculous skill of ancient times.

"Perhaps only the great power of the ancients can create such miraculous feats!" Li Yi secretly admired and was completely impressed.

Walking towards the wooden barrel, the volatilized poisonous blood qi was no longer harmful to him, but under the urging of the "Demon Refining Technique", it was refined into a trace of pure life essence and integrated into his flesh and blood.

Looking at the terrifying snake demon blood in the barrel, Li Yi gritted his teeth and sank his palm into the demon blood.

A sharp and intense pain spread from his palm to his whole body in an instant, and he felt as if his hand had reached into a volcano, being swallowed by lava little by little.

The blood of the snake demon can be corroded even by mana, let alone flesh and blood?

The sharp pain in his heart almost made Li Yi faint, and he could feel that the blood of the snake demon was eroding his body.

But after he stabilized his mind and urged the "Demon Refining Technique", the snake demon blood shrank at a speed visible to the naked eye as if it had encountered a natural enemy.

Streams of majestic life essence poured into Li Yi's body, strengthening his musculoskeletal body, purifying his body, and forcing out all the impurities in his body, all of which were black dirt.

His flesh was constantly being transformed, becoming purer and more powerful.

It's like the second development, but it's not the development of the body, but a qualitative change, after fusing the blood of the snake demon, his bloodline is no longer a human bloodline, but a half-human and half-demon, able to continue to cultivate mana like a human, and at the same time has a strong physique unique to the demon race.

I don't know how long it took, but the blood of the snake demon was finally refined.

Li Yi clenched his fists and felt a majestic force surging out, as if a flood beast was about to rush out of his body.

A punch was blasted out, and I saw that wherever the fist went, the incomparably hard boulder had a deep fist mark, and his face suddenly showed disbelief.

"This ......"

Li Yi was a little incredulous, his realm was still Tongxuan Yizhong, but the power of this punch was even a few points stronger than that of ordinary Tongxuan Duo disciples, almost comparable to the peak of the Duo Xuan.

And he didn't even use mana for this punch, otherwise the power would have been stronger.

He was ecstatic, feeling the thrill of having power for the first time.

Then, he began to meditate and cultivate, and found that the speed of absorbing the aura of heaven and earth was several times faster than before, and the blood of the half-human and half-demon greatly strengthened his affinity with the aura of heaven and earth, and the meridians and dantian also became stronger, and after a week, the mana increased almost at a rate visible to the naked eye.

Within a day, his long-stagnant realm broke through from the middle stage of the first to the late stage, and finally reached the peak, although he failed to break through the shackles and step into the double level of Tongxuan, but the capacity of his dantian was far larger than that of ordinary people, and the strength of mana was no worse than that of the second one.

"I didn't expect that the blood of ordinary demon beasts was so useful!" Li Yi suppressed his joy and secretly longed, "If I refine a powerful demon beast with supernatural powers, I don't know how strong my strength will be?"

Early the next morning, Li Yi left his residence, walked through the square, and came to a huge stone monument on the south side of the college.

The name of the stele is called the Bounty Tablet, and whoever in the academy needs to find someone to help can issue a bounty order here.

All kinds of reward orders were dazzling to look at, but Li Yi felt that the rewards were too low, and the highest was only a few dozen merit points, so he didn't make a move, and suddenly, a reward order attracted his attention.

Under the bounty order, there was a deacon disciple of the Refining Pavilion, who said with a full heart, "Does anyone dare to accept this order?"

The above task requires a team of four people to go to the outskirts of the Netherworld Forest, find a wind wolf cub that has recently been detected, and cut off its tail and bring it back, published by an elder of the Refining Pavilion.

Dozens of miles away from Lingzhou City, there is a forest sea, called the Netherworld Forest, the reason why it is named Netherworld is that there are some extremely powerful demon beasts living in it, ordinary people dare not approach there at all, and some monks who are not strong enough to break in rashly is also a dead end.

Many people gathered around and exclaimed.

"A thousand merits?"

"This bounty order is worth dozens of ordinary bounty orders!"

"Then you have to have a life to take it, wind wolf cub, is it so easy to deal with?" someone said this, and the enthusiasm of others suddenly cooled down, and their faces were full of frustration and helplessness.

The reason why the wind wolf got its name is because it was born with a magical power, called the wind supernatural power, which can resist the wind, and the speed is extremely fast, faster than lightning, as for how fast it can be, there is no conclusion.

Magical demon beasts are different from ordinary demon beasts, even if they are young beasts, they are also awe-inspiring and inviolable.

"It's just a young beast, you don't have to kill it, you just need to bring the tail back, don't you dare to take it, your courage is too small, right?"

Still no one responded.

"Unless there is a master of Tongxuan Triple or above to lead the team, the danger is too great, and you can't even save your life, so what's the use of the high reward?" an older disciple analyzed.

"yes. The others nodded in agreement.

It's just that such a master, who spends most of his time in retreat and cultivation, is out of nowhere, how could he come to such a place?

"I took this reward order!" Suddenly, a voice sounded, and I saw a young man who was not amazing come out of the crowd and took down the reward order, it was Li Yi.

Everyone thought it was a master who appeared, but when they looked at it, they were in an uproar.

I saw that his cultivation was only one of the most important things, which was inferior to most of the people present, such a waste, he actually dared to take orders?

Aren't they even as good as waste?

The crowd felt like they had been slapped in the face.

"Guy who doesn't know the height of the sky, hurry up and get out of the way, don't be ashamed!"

"If you want money and don't want your life, what can you do?"

The deacon disciple also frowned, and said secretly: "Is this kid here to make trouble? Even if no one takes the order, it won't be his turn!"

"Courage?" Li Yi secretly felt funny, his true strength was actually better than almost everyone present, not to mention that with ancient miracles such as "Demon Refining Technique", he was the nemesis of all demon clans, with this as a backing, he had the confidence to join, just by guts, he was not a fool, he had to be able to die.

"Hero, I'm afraid it's a bear!" A short disciple sneered and walked out, followed by a burly boy and a slender girl, "Give me this reward order, with me Zhang Cheng leading the team, just a wind wolf cub, why be afraid?"

"Zhang Cheng?" Many people were secretly surprised when they heard this name.

This Zhang Cheng is not small, he worships under an elder in the alchemy room, he is proficient in the art of alchemy, his mana is extremely strong, he has reached the peak of the double layer, and he is only a line away from the triple of the Xuan, and it is only a matter of time before he breaks through.

The two behind him, Wu Yue and Bai Muxue, are all his followers, and their strength should not be underestimated.

The deacon disciple was overjoyed, clapped his hands and said, "Senior Brother Zhang personally went out on the horse, that is the best!" said to Li Yi: "Give him the reward order, let him lead the team, and listen to him in everything." ”

In fact, this deacon disciple was very worried about Li Yi, but it was not easy to cross the river and demolish the bridge, so he wanted Zhang Cheng to lead the team so as not to get anything wrong.

Li Yi frowned slightly, but now is not the time to show his strength, not to mention that whoever leads the team is the same, he also saves trouble, so he handed over the reward order to Zhang Cheng.

"Okay, I wish you four success in your horses, go and come back quickly!" the deacon disciple said goodbye.

Li Yi and the others left the academy, passed through the city gate, and rushed in the direction of the Netherworld Forest.

It took me half a day to see a deep dense forest from a distance, covered with dark clouds, and it was quiet all around, revealing a breath of death, which was the Netherworld Forest.

The four of them marched step by step, relying on the map markings on the bounty order, and cautiously marched towards their destination.

Their purpose was only for the wind wolf cubs, and they didn't want to alarm any other demon beasts.

Li Yi walked at the end, carefully guarding along the way, while observing the actions of Zhang Cheng and the others, it seemed that the three of them were not the first time to come to the Netherworld Forest, and they were quite familiar with the route of travel, which areas could be traversed and which areas must be bypassed, all of them were clear.

"It seems that it is not bad for him to lead the team. Li Yi nodded secretly, he had never entered the Netherworld Forest, and if he was to lead the team by himself, he would probably not be able to move an inch.

At the same time, as the wind wolf's lair approached, Li Yi also felt a little nervous and excited in his heart, the power of the wind magic power, he had only heard of it in the past, and today he finally had to witness it with his own eyes.

Suddenly, Zhang Cheng, who was walking in the front, stopped, raised his hand and said, "There is movement." ”
