"Hehe, I believe that with the talent of Brother Yinhan, I will definitely be able to meet the requirements of the following, as for the roll and leave......" Bi Yan hehe, the red light flashed in his hand, and I don't know when there was an extra fist-sized blood-red spar.

The spar was crystal clear, slightly glowing with a strange red glow, and there seemed to be countless insect-like blood threads in it that were slowly turning, looking a little mysterious.

"This is the Blood Curse Crystal, what Brother Biyan means......" Liu Ming glanced at the spar, and didn't seem to show any surprise.

On the way to this blue and secluded city, Liu Ming also learned a lot about the ghost clan more or less, and knew that this blood curse crystal was a rather ancient thing like a blood oath law deed of the ghost clan.

"Brother Yin Han would be even better if he knew about this thing! This book is precious and abnormal, just in case, you and I might as well swear a blood curse to show our sincerity. Bi Yan said with a smile.

Liu Ming's eyes flashed, and without thinking too much, he nodded and said that he had no opinion.

Seeing this, Bi Yan immediately threw the blood-red spar in front of him, and raised his hand to punch into a magic decision.

The blood-red hedron immediately hung between the two of them, dripping and spinning out of thin air.

After Bi Yan glanced at Liu Ming, he stretched out a finger, forced out a drop of blood from it, and then flicked his finger to make it fall on the blood-red spar.

But as soon as this drop of blood touched this blood-red spar, it turned into wisps of thin hair-like blood, and directly submerged into the spar.

Immediately afterward, the dense insect-like blood in the spar seemed to suddenly come to life, and began to swim quickly in the spar.

Seeing this, Liu Ming also drew a gourd in the same way, and raised his hand to drip a drop of blood on the spar.

As the blood submerged, the speed of the blood in the spar increased sharply, and it seemed that it was about to break through the stone in the next moment.

The two immediately glanced at each other, raised their palms to the sky at the same time, and after making an oath to abide by the agreement, the blood-colored spar hanging between the two of them suddenly burst into blood, and made a "pop" sound, and directly shattered.

Dense insect-shaped blood threads came out from the shattered place**, and under a roll, they turned into two blood rays, one escaped into Bi Yan's forehead, and the other flew into Liu Ming's forehead, and disappeared.

Liu Ming only felt a burst of cold and biting cold air along the center of his eyebrows, straight into his body, and after scurrying around his entire body, he suddenly burrowed into the sea of divine consciousness, turning into a crystalline object in the shape of a blood-colored insect, curled up on the black and white true pill.

He urged the spiritual power in the sea of divine consciousness and touched the blood-colored worm.

As a result, the blood-colored insect did not move at all, as if it was a dead thing, but Liu Ming was still keenly aware of the fierce aura contained in the blood-colored insect.

"Now that the vow is over, I will take my leave, and I will see you in two months. Liu Ming arched his hand, put away the blue book in his hand, glanced at one of the walls of the secret room intentionally or unintentionally, turned around and walked out of the secret room.

After Bi Yan saw Liu Ming out of the room, he slowly sat back on the stone chair, poured a cup of spiritual tea, and took a sip gently.

At this moment, there was a clicking sound in the secret room, and a hole appeared in one of the walls, and a white-haired old man slowly walked out of it.

Bi Yan didn't show the slightest surprise on his face, he was still sipping tea by himself, obviously knowing that this person was here.

"You just handed over the Hell Codex to this ghost clan of unknown origin so lightly?" the white-haired old man looked at Bi Yan and said with a frown.

"Hehe, the book is the most suitable thing to trade with others, because it can be copied by thousands of people, as long as you make an oath, you will always make a profit. The Hell Codex is dispensable to me, and it would be of great benefit to us if we could get a strong arm. Bi Yan smiled and said unappetizingly.

"Even so, this Yin Han is just the early stage of a true pill. According to what you said, thirty or forty years ago, it was just a fake pill cultivation, maybe it was only a true pill that had been condensed in the last few years, and the realm was still not stable! The white-haired old man's expression lagged for a moment, and he snorted coldly.

"This Yin Han is by no means as simple as an ordinary True Pill, you know that my intuition has always been very accurate. In addition, I had also seen him shoot at the beginning, and the Dragon and Tiger Hell Skill he used was indeed quite powerful, and it was already able to stimulate the "supernatural power" of Hell Hell, which was enough. Bi Yan said with a flash in his eyes.

"There is such a thing!" said the white-haired old man, whose face changed, and who was surprised.

"Being able to cultivate the Dragon and Tiger Hell Skill to the end of the world without the premise of an auxiliary method, I'm afraid that there are few people in the entire underworld who can do it, and the power of his divine sense is also extremely powerful, although he didn't say it just now, it is estimated that he has already discovered that you are hiding inside. Bi Yan said with a slight smile.

"Impossible! Even those Heavenly Phenomena Realm City Lords may not be able to discover my Hidden Secret Technique, this son has just entered the early stage of the True Pill, and it is impossible for him to have such a powerful spiritual power......" The white-haired old man was a little surprised when he heard this.

"Hehe, don't believe it, but the stronger this Yin Han strength, the better, it seems that you and I really have hope of catching the Void Spirit this time......" Bi Yan said this, a cold light flashed in his eyes, and he held the spirit tea with a hard hand.

With a "click", the cup in his hand was directly pinched into powder and fell.

The white-haired old man Zeer's expression was cloudy, as if he was wondering what Bi Yan meant just now.

......

After Liu Ming left the VIP building, he didn't have the heart to participate in the next auction meeting, so he left Ruiyou Pavilion directly and returned straight to the inn where he lived.

Walking into the secret room of the inn, he waved his hands again and again, and a ray of light wrapped in the array flag shot out from his hand, and they all disappeared into the room, and after laying several layers of prohibitions one after another, he walked to the center with peace of mind and sat down.

Immediately afterwards, he flipped it with one hand and took out the blue book given by Bi Yan, and wrote four big characters in ancient script on the cover, "Hell Codex".

With a light breath, he opened the book, and the lines of small words and patterns on the pages were clearly arranged, which immediately attracted all his attention.

Little by little, time passed.

An hour later, Liu Ming closed the book and tilted his head, his face showing a look of thought.

There wasn't much content in this classic, and after he had already cultivated the sixth-level Dragon and Tiger Hell Technique, he didn't seem to have encountered any bottlenecks, so he quickly read through the contents.

According to his judgment, the records in this book are indeed all experiences in the cultivation of the Dragon and Tiger Hell Gong, and some of the understanding of the exercises makes it feel like a sudden opening, and many of the details that were not originally mentioned are mentioned one by one, which is very inspiring.

In addition, there are some tricks to the exercise of this technique, and many insights are refreshing to him.

However, it recorded the auxiliary method of the Dragon and Tiger Hell Gong, which made him a little puzzled.

According to the classics, when the cultivation of the Dragon and Tiger Hell Gong reaches a high and deep level, at each stage, some foreign objects are needed to integrate into the Dragon Tiger Gate Hell Gong in order to break through the bottleneck and greatly increase its power.

"Blend in with the outside world, I see, I see. "Because in the Dragon and Tiger Hell Gong classics he got back then, it had already mentioned the idea of relying on the assistance of foreign objects, so Liu Ming was not very surprised to say this in the classics......

According to the auxiliary method, when the Hell King practiced the Dragon and Tiger Hell Gong, he actually incorporated a large number of extremely precious heavenly and earthly treasures into the exercise, so that the power of this exercise could be greatly increased.

Of these treasures of the underworld, Liu Ming only knew one of the treasures of the "Cold Flame Pycedony Jade", which was extremely precious, and was said to be a kind of yin attribute spiritual material that could strengthen the physique, and had not appeared in the Nine Shadows for hundreds of years. As for several other heavenly and earthly treasures, I have never heard of them, but judging from their names, they should all be yin attributes.

"Since the Dragon and Tiger Hell Skill can be integrated into these Yin attribute treasures, it should also be able to be integrated into other external objects. Liu Ming pondered for a long time and muttered.

Thinking of this, he said that he would do it, and at that moment he took out several precious Yin attribute heavenly and earth treasures among the tributes of Cold Water City, since it was difficult to sell, he simply took them and tried them himself.

Liu Ming first picked up a spirit grass that was as black as ink, which was one of the tributes of Cold Water City, the Ghost Grass of the Dead Grass.

This thing contains a very heavy cold aura, which may be useful.

After looking at it in front of his eyes for a while, he rubbed his hands, and the black qi on his body gushed out, wrapping this ghost grass inside.

There was a soft sound of "snort", and the ghost grass was crushed in an instant.

Liu Ming's expression froze, and he hurriedly followed the method recorded in the classics, trying to integrate the cold spiritual power in the Ghost Grass into the billowing black qi transformed by the Dragon and Tiger Hell Skill.

Two hours later, the black qi on his body slowly dissipated, and some of the cold qi of the Ghost Underworld Grass was integrated into the Dragon and Tiger Hell Skill, but it did little to improve the power of the exercise.

"It seems that this Ghost Grass and the Dragon and Tiger Hell Sect are not very compatible......," Liu Ming muttered to himself, and then picked up a black jade box on the ground, which contained a black jade-like crystal.

A black gas came out of his hand, enveloping the black jade crystal inside......

In the next three days, Liu Ming tried seven or eight kinds of precious materials in the tribute in a row, but the results were not ideal, only one kind of Xuan Blood Condensation Crystallization effect was not bad.

However, if you want to greatly increase the power of the Dragon and Tiger's Hell Skill, you need a large amount of Xuan Blood Condensation Crystal, and Liu Ming only has such a small piece in his hand, which is still one of the tributes paid by Cold Water City to the King of You, which is obviously worth a lot of money.

It is simply impossible to rely on this Xuan Blood Condensation Crystal to increase the power of the Dragon and Tiger Hell Skill.

"Could it be that it cost so much to get this Hell Codex, and it doesn't even play much use......" Liu Ming could only shake his head and smile bitterly.

Maybe he could find some other treasures in the future and try it slowly, but Bi Yan only gave him a time limit of two months.

"That's right!"

Liu Ming's eyes flashed, and he suddenly thought of something.

With a wave of his hand, there was an extra black gourd the size of a foot in his hand, which contained nearly a thousand drops of Styx heavy water that he had spent twenty years condensing. R1152
