In the dark night, an even darker demonic aura rose in the hands of the Emperor of the Underworld. Sizzle..." A heart in the palm of the hand, as if pushed by something from the bottom, a trace of buoyancy makes the heart suspended in the demonic qi, a trace of refining sound, there is no flame scorching and roasted meat quality changes.

The Emperor of Hades carefully observed, and after a minute, wisps of black smoke began to scatter and rise from the surface of the heart, drifting away into the air, gradually disappearing in the air, and a huge heart, as the black smoke continued to dissipate, began to slowly shrink, and the fleshy texture of the epidermis also disappeared, and began to become a little black.

In the refining of the demon qi, the heart that shrank smaller and smaller, began to turn and roll up unconsciously, and after a while, the black gas floating into the air gradually faded, until there was no black gas floating out of the heart, the Hades Emperor only then restrained the demon qi, the original black gas, which can be said to be the toxins in the heart, was only refined by a trace in the refining of the demon qi, and now the heart in the hands of the Hades Emperor has become a black thing the size of a walnut, which does not look round and full, but is a little dry, as if it has been stripped of water.

The toxin is gone, so is there still an external qi source in this refined heart? The Hades Emperor looked at it with his black eyes, the blue light source was still there, and the concentration of the light source seemed to be more refined because of the dissipation of the toxin.

The Hades Emperor took this refining heart to his nose and smelled it, and his brows furrowed slightly, "Although the qi source is more refined, why is the quiet aroma lighter, is there anything missing in it?" The dry heart passed through the tongue of the Emperor of the Underworld, and the Emperor of the Underworld, who had a sense of taste, felt a trace of bitterness, and followed the heart into the abdomen and was dissolved by the demon qi, and the demon qi absorbed this source of qi, which was not much different from the past, but this bitter taste made the Emperor feel that something was wrong, "No..." The Emperor of the Underworld read in his mouth: "The demonic qi is useful for medicinal materials, and the effect of refining the potion is not something that the medicinal materials themselves can do, if the demonic qi can also be useful to the heart of the monster, but why does the taste bring a bitter taste, and there is no greater change in the absorption of the qi source" The Emperor of the Underworld was a little disappointed in his heart, "Is it that he thinks too much, and the demonic energy can't play a better role in the heart of the monster at all?"

The Emperor was disappointed, so he walked towards the house, but when his hand was about to open the door, he suddenly understood something in his heart, "No... I'll have to do another experiment before I'm willing," the Emperor of the Dead thought to himself, and disappeared outside the house with a kick of his footsteps.

"Huh?" Borg opened the door from the house, looking out, "I thought it was the king?" and closed the door again.

In the snow, the body of the Immortal Emperor moved extremely fast, and his eyes glanced at his chest, "Fangs... You just stay in my ring for a while, I have something to do now" The ring lightly touched his chest, the light in his clothes flashed, and the fangs were inhaled into the ring, and the body of the Hades Emperor rose into the air, shrunk into a black bat and rushed straight into the air, flapping his winged arms, and the black eyes that appeared looked around for a light source.

"Yes," the Hades Emperor was overjoyed, and there was a group of light sources moving ten miles to the east, "There are still a lot" The winged arms flapped, and the body flew out, "I must figure this matter out." ”

Ten miles away in the mountain, a small cave, just used by some monsters to avoid the wind and cold, but now this small cave is a little lively, different two voices in the cave emitted fierce sound waves, it seems that there is a battle, the two voices are full of hostility.

"Micro~~~" A sound like a pig screaming undulated in the cave, a pig ran back and forth in the cave, surrounded by a group of smaller pincer ants, and seemed to have identified the pig as their own food.

Pincer Ant: C-rank primary monster, shaped like a soldier ant, with white skin like albinism, the size of a domestic cat, black eyes and two tentacles on the top of the head, you can quickly find the prey you need, and there are a pair of pincers with sharp teeth on both sides of the mouth, which seems to be an effective attack weapon, and the elements contained in the body are gold.

"Sizzle..." There are about more than 30 pincer ants to surround the pigs, making a hostile sound to the pigs, running around the pigs, with their own fangs to hit the pincer ants, some pincer ants did not have time to dodge, were hit and flew up, and even some pincer ants were knocked off their antennae.

Although the pig is a lot bigger, but after all, it is fighting alone, I am afraid that it is also because of the wind and cold to come to this cave, so it was surrounded by these pincer ants, if you want to defeat these pincer ants, the pig alone can not be done, after all, the pincer ants have a numerical advantage, the pig looks at the direction of the cave mouth, and rushes out.

"Flutter... Flutter... Some pincer ants blocking the mouth of the cave suddenly spit out some transparent saliva from their mouths "Micro~~~" The fangs also let out a terrible scream, and the fur sprayed by the saliva of the pincer ants raised a trace of white mist "Sizzle..." The corrosive sound shows that there are some acidic corrosive effects in the saliva spit out by the white pincer ants, and other white pincer ants have also become smarter, and they are smaller, and they have to use their own saliva to control the enemy. Flutter... Continuous saliva sprayed onto the pig's body.

The pig howled, the intense pain caused by corrosion, so that the pig flowed blood, uncomfortable fell to the ground, a white pincer ant saw the opportunity, clamped its own mouth tongs, and cut the throat of the pig, so that the pig died.

"Sizzle..." The white pincer ant colony was a little excited, and the food finally arrived, but at this time, a dangerous breath came from outside the cave, which made the body of the white tong ant colony shiver unconsciously, and hurriedly looked at the hole entrance.

The figure of the Hades Emperor walked in: "I want this pig's heart!"

Seeing that the Emperor wanted to snatch the hard-earned food of his group, although he was afraid, he also wanted to make a final effort. Flutter... The corrosive saliva in his mouth squirted towards the body of the Immortal Emperor.

The Hades Emperor frowned slightly, a slight pain came from his skin, and the slightest white mist told himself that these saliva were dissolving his skin "Hey~" The Hades Emperor was displeased for a while, "Speaking of dissolving... Your corrosiveness is still a lot worse" A demonic aura burst out from the surface of the Hades Emperor's body, and the saliva that remained on the skin disappeared into the air in an instant, and a trace of mixed blood aura restored the rotten skin to its original state.

The saliva of the white pincer ant continuing to attack the Hades Emperor also melted when it came into contact with the demonic energy, and the helpless white pincer ants saw that the Hades Emperor walked towards the pig without hindrance, and had no choice but to stop attacking "I don't want your food" The Hades Emperor disemboweled, and after taking out the heart he wanted, he left the corpse behind.

In the snow, the Hades Emperor held the heart in his hand, the demonic energy rose again, the slightest black gas dissipated, and the heart shrunk again, becoming dry and dehydrated, but this time the Hades Emperor did not retract the demonic energy, but transmitted instructions to the ring, a bottle of medicine appeared in his left hand, his demonic energy is a product produced by the mixture of the demon's heart toxin and the toxins of various medicinal materials and medicinal properties, the heart has not been refined, maybe it is the addition of less medicinal materials, and now you only need to use ready-made potions to test, you can know whether the monster's heart can refine something new。

Open the cap, the medicine poured into the demonic energy, and at this time, the medicine did not flow to the palm of the hand like the general liquid when refining the potion, but as if attracted by something, floating in the demonic energy, began to move closer to the tumbling dry heart, and slowly fused into a piece, the tumbling dry heart has the integration of the potion, the appearance begins to be injected with water, the dry appearance begins to become full and full, suddenly the heart turns faster and faster, and "bang" after a minute stopped, and a pungent aroma full of extreme temptation was inhaled into the nostrils of the Emperor of the Underworld, and the Emperor of the Immortal retracted his demonic energy violently in his heart.

A round object the size of a walnut fell into the palm of the Emperor's hand, and the Emperor inhaled the aroma from the air again with some intoxication, and confirmed in his heart, "This is the new product I want." ”

Looking at it, the plane of the round object reveals a transparent blackness, as if a trace of light can be seen in the darkness, the shape is round and full, without any flaws, the Hades Emperor lifted this thing, and under the moonlight, it was like a huge black pearl "What should I call you?" the Hades Emperor pondered, "Pills?" or... Oh... It's better to call it a pill! It is mainly based on the heart of the monster, and then assisted by medicinal materials and potions. The medicine is behind, well~ it's called the pill" As soon as the Hades Emperor's fingers were thrown, the elixir was thrown into his mouth, and the small elixir was easily swallowed by the Hades Emperor, who was used to devouring his heart.

"Hmm~" The Immortal Emperor's eyelids jumped, "Hahahaha..." Unconsciously there was a burst of laughter, "This is the new product I want, this is the good thing developed by the demonic spirit" The elixir dissolved by the demon qi in the body, after being turned into a qi source, only a small part of it was absorbed by the demon qi, while the other qi sources were directly integrated into their own fighting qi, such direct integration was more and faster than absorbing the qi source from the demon qi before, and in this way, the qi source directly integrated into the fighting qi was also more retained, the Hades Emperor suppressed his laughter, touched the warmth that suddenly appeared in his lower abdomen, and the corners of his mouth were still smiling. The demon qi refines the toxins in the monster's heart, so it becomes dry, and the elixir fills the trace of deficiency, enhances the amount of qi source, and also brings the benefits of the medicine to the heart, in the elixir without toxins, the fighting qi can be directly absorbed, only a small part will be absorbed by the demon qi and continue to enhance the characteristics of the demon qi, but in this way, there is less toxin, and the amount of qi source is enhanced, so that the pill that can be directly absorbed can be ten times more effective than directly swallowing the heart, and at the same time, it also directly strengthens its own muscles and bones, in other words, a person must have a good physique while improving the level, and the mobility of exercising the body is also essential, and the pill can improve the level of fighting qi, and at the same time, it can also strengthen the muscles and bones of the body, helping the body to use more powerful fighting qi, the elixir... Pills··· Hahahaha..." The Immortal Emperor laughed again, "The era of potions? It's not just the era of potions, who said that there is no shortcut to improving strength, I am the creator of shortcuts!"
