The demon core is a kind of energy crystallization unique to demon beasts, and it is also the source of the ability of demon beasts, and it is the fundamental symbol that distinguishes beasts from demon beasts.

The snake and horse beast is the pinnacle existence of the third-order demon beast, but its demon core is no more than the size of a little finger, Qin Yin gently lifted it up with two fingers, and came to the front of him to take a closer look, but saw that this demon core was an irregular hexahedron, crystal clear, and there was a faint liquid flow in it, holding it in his hand, he could even clearly feel the surging energy in this demon core.

"Hmm, this is ......" Qin Yin took a step and stepped over a piece of ice slag and was about to walk towards the cave of the snake, horse and beast, but in the corner of his sight, he saw a small embroidered bag in a pile of ice slag.

This embroidered bag is turquoise, embroidered with bamboo and plum, small and exquisite, even under the low temperature of Qin Yin's ice and frost, it is still intact, after getting it, this small embroidered bag is exuding a trace of warmth.

"Isn't this the legendary space bag? It looks like a small bag on the outside, but the space inside can hold a space bag that is more than ten times or even dozens of times the size of an ordinary bag?"

Taking this space bag and looking at it carefully, Qin Yin recognized the origin of this embroidered bag after thinking about it for a while, and a touch of ecstasy swelled up in his heart.

The value of the space bag does not need to be described, and the materials used to make the space bag are also extremely precious, and the most scarce of them is a material called space crystal.

Qin Yin has carefully searched for some information about the space bag in some Zhiyi anthologies, although he can't say that he knows the space bag well, but at least he still knows a lot about how to collect the objects in the space bag and other popular usage.

I saw him gently bite his fingers and smear the gushing blood on the mouth of this dark green space bag, and then, a wonderful feeling came to his heart, and at the moment when the blood was smeared all over the mouth of the bag, there was a unique connection between him and this embroidered bag, as if he was connected to a special space that could be given up at the end of his fingers.

This space is about a foot square, and it is filled with a dozen or so small jade bottles, several coats, and three paper cheats.

"Out!"

Qin Yin's heart moved, and he silently recited in his heart, and suddenly, a secret book selected by his own mind magically appeared in his left hand, as if it was originally there.

Holding back the excitement in his heart, Qin Yin roughly flipped through the cheats book in his hand, and found that it was a Xuan-level low-grade knife technique, called "Blue Blood Knife", the knife technique is sharp, and the moves are deadly, which is a unique study born from the battlefield combat method.

"Close!"

Although "Blue Blood Knife" is sharp, it is only a Xuan-level lower-grade exercise after all, and Qin Yin, who has already begun to study the half-style residual move of "Ice Spirit Cold Light Technique", has improved his vision a lot with the intensive study of this half-style residual style, although this Xuan-level lower-grade knife technique is mysterious, it takes a certain amount of time to study, but he generally remembers the number of ways of this knife method, and with his mind in mind, he put this secret book into his bag.

"Out!"

After putting the cheats of "Blue Blood Knife" into the bag, Qin Yin's mind moved, and the next moment, a small jade bottle appeared in the palm of his hand, pulled out the stopper, and a strong medicinal fragrance came to his nose.

"Scattered Flower Jade Dew Pill, a medium-grade healing medicine, one is worth five thousand gold, and one bottle is three, this Cheng Jiu's family background does not seem to be simple. ”

Qin Yin, who had lived in Lord Wen's place for a while, recognized the name and grade of this elixir at a glance, although the Scattered Flower Jade Dew Pill of this medium-grade healing medicine could not be compared with the top-grade or even the best elixir provided by Lord Wen, but after all, Lord Wen was the only daughter of the Great Xia Military God, and he was also the county lord of the Great Xia Emperor, and his power and wealth were not comparable to ordinary families, so this medium-grade wound medicine was just an ordinary thing in the eyes of Lord Wen. However, in Qin Yin's eyes, this wound medicine is a great thing, especially in the Liubo Mountain Range, there are many dangers, I don't know where those powerful demon beasts are hiding and waiting, there is a danger of being injured at any time, and there are some wound medicines on their bodies, which are enough to deal with some situations.

Counted the items in the space bag, a total of nine bottles of scattered flower jade dew pills, another bottle of Qingyun Dan, two cans of snow clam cream, twenty golden tickets, three cheats, a peculiar jade pendant, and several sets of brocade robes and other clothes, Qin Yin quickly discarded some of the clothes that he didn't need, and threw the backpack on his body into the space bag, but the moon shooting bow on his body was too large to fit into the space bag, and it could only be carried on his shoulder.

Following the path that the snake and horse beast crawled over before, Qin Yin easily stepped into the cave of the snake and horse beast, and was greeted by a pungent smell of smoky hot and dry breath, and the cave was extremely dim, but for Qin Yin, who had broken through the innate realm, all this was not a problem, with the light leaking from the cave entrance, after walking through a winding narrow road, his eyes suddenly opened up, and there was an arc-top cave with a radius of more than ten zhang.

The four walls of this curved cave are inlaid with thick bluestone slabs, and there are several small ventilation holes diagonally above, leaking a few rays of light as thick as little fingers, making the cave dim but not dark.

This cave has obvious artificial traces, I don't know who opened it, and I don't know how many years have passed, the bluestone wall is mottled and dilapidated, Qin Yin carefully observed everything in this cave, Leng Bufan's feet were mixed, as if stepping on a soft flesh with some temperature, through the light leaking from the top of the arc, it was faintly visible that it was a human corpse, but this corpse was black, as if it had been coated with a layer of ink, and its whole body was swollen like a big fat man, but from the outline of the face, it could be vaguely distinguished that it was Ge Ning, a brocade-robed young man who had entered the cave with Cheng Jiu。

Qin Yin took a few steps back, frowned, more cautiously, and looked around carefully, the muscles and flesh all over his body were stretched like a tight bowstring, and for a while, only the sound of Qin Yin's long breathing was left in this dim cave.

From Ge Ning's death, it is not difficult to infer that he must have been poisoned during his lifetime, but as far as Qin Yin knows, although the snake and horse beast are extremely ferocious, with a snake head and a horse body, it is actually a non-poisonous demon beast, that is, in this cave, there must be a poisonous source that Qin Yin has not yet discovered!
