Heaven-defying Upgrade System

The fur of this Double-end Coyote was a good thing, but it was now riddled with holes by Liu Fei. He couldn't take it anymore. Now that it was dead, its bones were dead, and there was nothing it could do. However, he could take away the wolf claw that he had trained with great care.    

    

Therefore, Liu Fei cut off the wolf claw from its bones and put it into the system package. Then, he dug into the Double-end Coyote's body.    

    

The inner core of the Demonic Beast was the essence of flesh and blood. It was different from the inner core of a cultivator. The inner core of a cultivator was usually in the upper dantian. It was in the form of a non-material Yuan Spirit, while the Demonic Beast Inner Pill was in the shape of a meatball.    

    

The size of the pigeon egg in his hand was similar to that of a pigeon egg. After washing away the blood stains on the egg with clear water, the surface of the egg was blood-red, and there was a faint green pattern on it.    

    

This was a one-patterned Demonic Beast Inner Pill.    

    

There was a total of ten grades of Demonic Beast Inner Pill, and those without patterns were the lowest grade. After that, there was a one-patterned ___, a two-patterned ___, a three-patterned ___... and finally, a nine-patterned ___. Each line was further divided into upper, middle, and lower levels. Looking at the inner core of the Double-end Coyote, the green line was not very obvious. It should be because he had just cultivated the line not too long ago. It was a low tier one-patterned Demonic Beast Inner Pill.    

    

The Demonic Beast Inner Pill could be used as medicine, or it could be used to craft weapons. It could also be used to set up formations. Its uses were quite extensive. In the outside world, the Demonic Beast Inner Pill was generally a relatively popular item.    

    

However, cultivators could not directly use the Demonic Beast Inner Pill. This thing had a lot of evil intentions. Apart from being processed, if one consumed too much, one's body would also be contaminated with evil energy. Moreover, it was very likely that it would transform from a human into a Demonic Beast. At that time, it would be too late to regret it.    

    

This was also Liu Fei's first time seeing a Demonic Beast Inner Pill. He took it to his nose and sniffed it. The thick smell of blood actually emitted a faint fragrance from time to time.    

    

"I wonder what kind of smell it is?"    

    

Liu Fei was very curious in his heart. Hence, he carefully stuck out his tongue and pressed it against the Demonic Beast Inner Pill. He licked it. Apart from the strong smell of blood, there was actually a hint of sweetness.    

    

Liu Fei found this feeling was quite fun, with a faint fragrance and a hint of sweetness. From time to time, it would impact the thick smell of blood and his taste buds. It made him somewhat silent, and he actually could not hold it in anymore. He could not help but want to swallow the Demonic Beast Inner Pill in one gulp.    

    

Thinking about it, he decided to forget about it. The consequences of directly swallowing this thing was very serious. He didn't want to transform into a Demonic Beast in the future.    

    

"Ding! System side quest triggered. This quest is a permanent cycle quest. Host can choose to hand over the Demonic Beast Inner Pill to exchange for experience points. According to the quality of the Demonic Beast Inner Pill, you can exchange for different amounts of experience points."    

    

"There's such a thing?"    

    

Liu Fei realized that the system was simply too cool. What he needed now was experience points, which corresponded to the cultivation base of War God Continent.    

    

He immediately contributed a Demonic Beast Inner Pill.    

    

[Experience + 10000]    

    

A low-grade one-patterned Demonic Beast Inner Pill could be exchanged for 10000 experience. Liu Fei found that he seemed to have suffered a small loss. A low grade one-patterned Demonic Beast Inner Pill. It could only be exchanged for one-tenth of the experience points of the current realm. If he were to buy it outside... Or refine it into an Elixir, the value of the Elixir would be higher than the value of the Elixir.    

    

However, doing those things required a lot of time. Time was money. Correspondingly, directly submitting a Demonic Beast Inner Pill to exchange for experience points did not seem inappropriate.    

    

Just as Liu Fei submitted the Demonic Beast Inner Pill, a wolf's howl suddenly sounded in his ear.    

    

Liu Fei immediately turned around and saw another Double-end Coyote!    

    

"This... has it come to the wolf's den?" Liu Fei was slightly shocked, then his eyes narrowed, as if he had thought of a bad idea. He waved the treasured sword and charged at the Double-end Coyote, shouting, "Little thief, hand over your Demonic Beast Inner Pill!"    

    

Indeed, as Liu Fei had expected, he had indeed come to the wolf's den.    

    

This place seemed to have been a wolf's den before, but it seemed like all the wild wolves had evolved into Double-end Coyote. After becoming an even more ferocious animal, the Double-end Coyote still adopted the method of living in groups. However, there was a certain distance between each Double-end Coyote, unless there was a heavy enemy invading. Otherwise, these Double-end Coyotes would only hunt for food and cultivate within the range of their own activities.    

    

Liu Fei relied on the suppressive effect of the Flame Dragon Sword Spell on the Double-end Coyote to start a massacre in the wolf's den. He also collected more and more Demonic Beast Inner Pill.    

    

Unknowingly, a system notification rang in his ears.    

    

"Ding! Congratulations to host for leveling up. Current level is 13, corresponding to the cultivation base of War God Continent - Third Sky of Mortal Core Stage!"    

    

With another increase in cultivation level, Liu Fei did not need to waste any more effort to deal with these Double-end Coyotes. It was like a tiger entering a pack of wolves, killing whenever it saw a wolf. It was just some wild wolf cubs that had yet to evolve into Demonic Beast. Liu Fei let them off for the time being.    

    

When the wolf pack noticed that a strong enemy had intruded their territory, they all gathered around, but it was already too late.    

    

At this time, Liu Fei was more familiar with the Flame Dragon Sword Spell. With the consumption of some of his experience points, he had successfully comprehended the second style of the Flame Dragon Sword Spell - Dragon Breath Thorn.    

    

Facing the continuous gathering of Double-end Coyote, Liu Fei started a massacre. When the spiritual energy in his body was insufficient, he did not hesitate to use the Spirit-Resumption Talisman to replenish his spiritual energy.    

    

When the crescent moon was suspended in the air.    

    

Liu Fei had already stepped on the corpses of nearly a hundred Double-end Coyotes. Looking at the mountain full of corpses, Liu Fei suddenly had a feeling of playing a game and farming monsters. He felt a sense of accomplishment.    

    

Furthermore, his cultivation base had also successfully advanced to the Fourth Heavenly Layer of the Mortal Core Stage!    

    

Stepping on the silver moonlight, after Liu Fei dealt with the last Double-end Coyote, he discovered a strange cave. Thus, under the urging of curiosity, he walked into the cave.    

    

A ball of fire lit up in his hand, lighting up the cave.    

    

In an instant, Liu Fei was dumbfounded.    

    

In this cave, there were actually dozens of young wolves waiting to be fed, and a huge Double-end Coyote. They were like a female wolf that had just given birth.    

    

Under a stone platform they were lying on.    

    

They were covered in a kind of silver star-like grass, and their eyes were blinking in the cave. They were extremely beautiful.    

    

"Silver Pearl Spirit Grass!"    

    

Liu Fei was shocked. It was actually a precious Silver Pearl Spirit Grass. He didn't expect this kind of thing to be in this place! A few little wolves that could walk were eating in the grass.    

    

Liu Fei suddenly realized. This Double-end Coyote was cultivated by consuming the Silver Pearl Spirit Grass. That was why there were so many Demonic Beasts on this mountain.    

    

Looking at the female wolf who was glaring at him angrily, Liu Fei mercilessly raised the treasured sword in his hand and killed it with a single strike. After the female wolf gave birth, it was already exhausted, so it was unable to deal with Liu Fei's sudden attack.    

    

"I'm sorry, I only took your Demonic Beast Inner Pill. Your children and these young ones will live on." Liu Fei did not care if she understood or not. In any case, that was what she said.    

    

The female wolf let out a long and miserable howl, and finally died from anger.    

    

Liu Fei took out the Demonic Beast Inner Pill in her body. It was actually a high-grade one-patterned Demonic Beast Inner Pill! This female wolf's combat strength was astonishing. It was on a completely different level from the Double-end Coyote outside. If it wasn't for her having just given birth, Liu Fei wouldn't have easily gotten his hands on it.    

    

After obtaining the female wolf's Demonic Beast Inner Pill, Liu Fei wasn't in a hurry to hand it over to the system. Instead, he put it away first. Perhaps he would use it in the future.    

    

After that, Liu Fei took away a large portion of the Silver Pearl Spirit Grass.    

    

The Silver Pearl Spirit Grass had to be harvested. Collecting more resources could bring glory to the family, and it could also help oneself gain prestige.    

    

After keeping the Silver Pearl Spirit Grass, Liu Fei wrapped it with a wolf skin and walked out of the cave.    

    

Just as he walked out of the cave, he suddenly heard the sound of fighting not far away from the mountain forest. It seemed that a disciple of the family had come here.    

    

Liu Fei immediately followed the sound and rushed there.    

    

Very quickly, a group of black shadows appeared in front of him, fighting each other under the faint moonlight.    

    

The ones fighting were two groups of people. There were about ten of them. If one looked closely, one could see that one group of disciples was wearing the Lee Family's family emblem, while the other group was wearing the Liu Family's family emblem!    

    

Furthermore, the disciples of the Liu Family were at a disadvantage.    

    

Although there was a First Sky Mortal Core Stage among the disciples of the Liu Family, it couldn't stop the suppression from one Mortal Core Stage Second Layer and two First Sky Mortal Core Stage in the Lee Family.    

    

Liu Fei only observed for a short while before the disciples of the Liu Family were in a miserable state. One of the disciples was unable to defend himself and was killed by a disciple of the Lee Family. Blood splashed in the air.    

    

"We can't fight anymore, retreat!" One of the disciples from the Liu Family shouted.    

    

The First Sky Mortal Core Stage disciple immediately shouted, "All of you, retreat! I'll stop them!"    

    

"Brother Chuanfeng!"    

    

"Don't worry about me! Quickly retreat and look for the Young Patriarch! Quickly go!"    

    

"Liu Chuanfeng?" In Liu Fei's memory, there was this person in the Liu Family, but he did not have a deep impression of him. He did not expect to see him today, which made Liu Fei secretly praise him, "He is a man."    

    

"Let's go! We cannot let Brother Chuanfeng sacrifice himself for nothing. Let's go and find the young master!"    

    

"Right! Take revenge for Brother Chuanfeng!"    

    

The disciples of the Liu Family quickly retreated. However, when they turned around and ran for a few steps, they immediately stopped in their tracks.    

    

They saw a black shadow slowly walk out of the shadow with its back facing the moonlight. It appeared in front of them and approached them step by step.    

    

"You... Who are you?" A disciple of the Liu Family cried out in shock.    

    

Who knew that when the black shadow walked in front of them, it didn't pay any attention to them. Instead, it coldly said, "A bunch of trash." After that, it moved like the wind and passed through the battlefield. The sword in its hand flashed with a cold light. A scorching fiery light pierced through the Lee Family disciple who was the closest to Liu Chuanfeng.    

    

"Bang!"    

    

The disciple who was stabbed was immediately engulfed by the flame. He didn't even have the chance to scream before he fell stiffly to the ground. His body gradually turned black in the flame.    

    

"Who is it!?"    

    

The disciples of Lee Family were shocked and immediately retreated.    

    

This was because the black shadow that attacked them just now had killed the strongest Mortal Core Stage Second Layer with just a single strike. How could they not be shocked by such a terrifying strength?    

    

Liu Chuanfeng originally thought that he was going to be buried in this trial ground, but the sudden change... It had changed his fate. Liu Chuanfeng looked at the black figure standing beside him. When he saw his face, he immediately cried out in surprise.    

    

"It's you? Liu Fei!"
