The hydra is about 20 meters long, and its waist is relatively swollen due to its nine heads, which are relatively small, but each of them is the size of a bucket.

From the very beginning, Ning Bizhen was in full swing, several six-pointed stars appeared, and the three-legged fire crow, the Tanabata wind speed cat, the night marten, the blue-eyed golden-eyed beast, and the young red dragon were summoned.

Counting the Han Jade Rabbit, there are a total of four lord-level demon pets and two leader-level demon pets, and as for the six-armed Naga given to her by Li Changsheng, she is still very weak.

The hydra, which was originally about to attack Ning Bizhen, forcibly stopped its forward trend, and the snake pupils of the nine heads shrank for a while, and looked at Ning Bizhen's six demon pets with frightened eyes.

The hydra's gaze was mainly focused on the three-legged fire crow, it was not afraid of the cold jade rabbit, but from the three-legged fire crow it felt a strong threat, if you count the other demon pets, faintly smelled the danger of death.

Deadly crisis!

The hydra shivered, and it subconsciously wanted to burrow back into the mud pond and use the large amount of silt accumulated in the mud pond to protect its life.

It's a pity that although its reaction is fast, in the end, the opportunity has been lost, and how can it outperform Ning Bizhen's six demon pets.

Under the command of Ning Bizhen, the six demon pets launched an attack on the Hydra in unison.

In the sky, the three-legged fire raven swooped down, its body spinning rapidly, as if turning into a small tornado, and its sharp beak glittered with cold light, pecking at one of the Hydra's heads.

The Jade Rabbit jumped up, its speed and bounce were excellent, and it also jumped in front of one of the Hydra's heads, and waved a punch, its fist was small, but it sounded a strong sonic boom.

Meow~

The Tanabata Wind Speed Cat fanned its azure wings, and suddenly rushed forward, the cyan mark on its forehead flickered, and a layer of cyan light curtain appeared on its body, on which countless trembling wind blades were attached, and it also crashed into one of the heads of the hydra.

On the ground, the night marten exuded a rich black energy, and countless black light points quickly converged, turning into a dark flame giant sword several feet long, breaking through the air and slashing at one of the heads of the hydra.

As for the Blue-Eyed Golden-Eyed Beast and the Young Red Dragon, they were slightly weaker and could only attack one of the Hydra's heads together.

In the blink of an eye, the five heads of the Hydra were attacked.

Hiss ~ Hiss ~ Boom ~ Bang ~ Boom ~

In the frightened and abnormal roar of the hydra, its five heads seemed to be made of tofu, and they were instantly exploded by Ning Bizhen's six demon pets, either falling to the ground, or exploding into a cloud of minced meat or blood mist.

In an instant, the hydra was left with only four heads.

Roar~

The hydra let out a roar of pain, and the remaining four heads were filled with a thick look of horror, there had never been a moment when it would face such a strong crisis.

After the five heads were broken, the hydra's severed limb regeneration properties came into play, and fine granulations grew from the fractures of the five heads, and it only took a few minutes for the five heads to complete the rebirth.

It's okay to say it in normal times, but this is still too slow for the current Hydra.

Without any hesitation, the hydra went directly into the mud pond, wanting to use the muddy mud pond to avoid the confrontation with Ning Bizhen.

Thundered~

The next moment, six pillars of light of different colors fell on the mud pond, and suddenly there was an explosion, as for whether it exploded or not, it was not clear.

This mud pond is too big, full of 100 acres in size, and the depth is unknown, and it takes a lot of time to drain and evaporate.

However, Ning Bizhen only has a water-based demon pet like the water-avoiding golden crystal beast, and he is still at the leader level, so he has nothing to do about the hydra cowering in the mud pond for a while.

Ning Bizhen looked at Li Changsheng and asked, "Changsheng, is Danwang Beppu in the mud pond?"

Li Changsheng didn't answer immediately, the wings of illusion extended from his back, and while feeling the traction on the map, he flew towards the mud pond.

Ning Bizhen hurriedly asked the three-legged fire crow to escort him.

When Li Changsheng stopped, he was in the sky above the center of the mud pond, and the traction direction of the map in his hand changed, trying to drag him to fly down.

"Well, just below the mud pond!"

Li Changsheng nodded and immediately flew back to Ning Bizhen's side.

"That's not going to be easy!"

Ning Bi Zhenxiu's eyebrows furrowed slightly, and she couldn't think of a good way for a while.

The Silent Forest was too dangerous, and it was near the territory of the Black Dragon Harikuchi, so they naturally wanted to open Tanwang Beppu as quickly as possible.

"Next!"

Suddenly, Li Changsheng threw two things to Ning Bizhen.

Ning Bizhen took a look and found that they were two orbs, one blue and one yellow, faintly emitting the corresponding light.

This is naturally the Cangxuan Ding Water Bead and the Cangxuan Ding Earth Bead, which can weaken the power of the hostile goblin's water and earth skills, and can also control the water flow and soil, mainly depending on the realm of the demon master.

With Li Changsheng's realm, if she controls two orbs at the same time, she can also control a range of tens of meters, but Ning Bizhen is different, she is a fifth-order demon master, and her control range must far exceed Li Changsheng's.

"I didn't expect you to have such a good thing!"

After Li Changsheng gave the effect of the two orbs to Ning Bizhen, Ning Bizhen sighed and couldn't wait to start the experiment.

Boom~

Ning Bizhen immediately injected a spiritual power into the two orbs, and the two orbs emitted a misty light together, automatically levitating in front of her.

The next moment, countless muddy water rushed up from the mud pond, and under Ning Bizhen's control, it turned into dozens of water dragons and earth dragons.

Boom~

The water dragon rushed directly to the river on the side, and for a while, the river swelled and surged down the river.

The earth dragon landed on the ground a hundred meters away, and in a few breaths, it was piled up into a mountain of earth, and it was still growing rapidly.

Hundreds of acres of mud ponds began to flow at a speed visible to the naked eye, and a larger and larger pothole appeared in the same place.

Ning Bizhen controlled the two orbs and said, "I can control a range of two or three hundred meters, and it won't take more than a few minutes to drain the muddy water here!"

When the two orbs were pulled out of the muddy water, the hydra under the mud pond was obviously startled, and its three corpse gods jumped violently, already feeling a serious death crisis.

Once the mud pond is completely dry, it is the time of its death.

Until then, it must be ready to save itself.

Under the mud pond, the hydra immediately moved to the edge of the mud pond, and the remaining four heads began to dig frantically into the hard ground at the edge of the mud pond.

Soon, Hydra dug a large pit large enough to hold it.

It immediately burrowed into it and continued digging ahead, preparing to dig a tunnel to escape.

This is also the only way Hydra can think of to escape.

In the face of life, Hydra is willing to give up territory.

However, the Hydra is not as good at burrowing as the Treasure Hunt Mouse, but its body is still very large, and it will take a lot of work to dig a passage for it to pass through.

In addition, the hydra, which has only four heads left, has a big gap in digging speed from its peak.

Boom~

With Ning Bi Zhen's continuous input of spiritual power, the two orbs began to spin drippingly, and a certain connection occurred between the two, which improved the efficiency.

In just two or three minutes, the mud pond finally bottomed out, and the whole mud pond was rapidly drying up.

After all the muddy water was pumped out, a large pit with a size of 100 acres appeared in the same place, and the deepest part was tens of meters deep.

In this large pit, the trace of the hydra has been lost.

Because the smell of the pit is so strong, it is difficult to sense the whereabouts of the hydra using the sense of smell.

However, this does not mean that Ning Bizhen does not have a way to track it.

"Marten, night tracking!"

Ning Bizhen pointed to the severed head of the Hydra and commanded the Night Marten to perform the bloodline inheritance skill inherited from the Nine-Eyed Mink.

The night marten stared at the severed head of the hydra, and its six eyes flashed with a strange light.

In an instant, the Night Marten's forehead slowly cracked, revealing a fist-sized pitch-black eyeball, shooting out a black light that landed on the severed head of the Hydra in the blink of an eye.

The next moment, a dark aura appeared on the skull, twisted in the air, and then landed in the big pit, flying towards the entrance of the passage hidden by the hydra.

The dark aura ignored the dirt and disappeared directly into the entrance.

"There, on!"

Ning Bizhen immediately stepped onto the blue-eyed golden-eyed beast and directly pulled away the dirt that blocked the entrance, revealing a dark passage, and the sound of digging dirt could be faintly heard.

Hydra hasn't dug a passage yet!

The unfinished passage was less than a hundred meters, and at the end of the passage, the hydra was still digging in the dirt, and when a dark aura appeared in front of it, it was visibly startled, and immediately realized that it had been exposed.

Ning Bizhen was moving forward while controlling the Cangxuan Dingdi Bead and quickly expanding the passage.

The passage dug by the hydra was already relatively spacious, and it was expanded by Ning Bizhen like this, even the size of a young red dragon could easily pass through.

"Kill it!"

With Ning Bizhen's voice sounding, the six demon pets quickly rushed into the passage and appeared behind the hydra.

Naturally, the hydra did not sit still, and under the effect of the regeneration properties of the severed limbs, the five lost heads had already appeared in silhouette, and they had more or less regained some strength.

In the next moment, the four complete heads of the hydra erupted, spewing out a four-colored pillar of light, and the five heads that appeared in silhouette continued to dig a channel towards the location of the river.

As long as you escape into the river, you can escape.

The Jade Rabbit let out a chilly breath and collided with the four-colored pillar of light in the blink of an eye.

The Hydra was obviously not in its heyday, and the four-colored pillar of light was naturally not the opponent of the Ice Breath, and after a pause, the Ice Breath began to suppress the four-color Breath and continued to rush towards the Hydra.

The Hydra's eyes showed a fierce light, and it immediately detonated the four-color pillar of light, directly blasting a large crater in the passage, and the cold wind pressure and energy tide could only spread to both sides.

At this moment, the three-legged fire crow spewed out a pillar of flame with red and gold, directly dispersing the energy tide and falling straight on the Hydra.

Roar~

The hydra roared in pain, but its five unformed heads were still digging into the ground, and it could already hear the sound of the water.

Ning Bizhen naturally guessed the intention of the Hydra, she immediately controlled the Cangxuan Dingdi Bead, and the ground in front of the Hydra quickly solidified.

Boom~

The Hydra's unformed head slammed into the ground, and he found that the ground in front of him had become as hard as iron, and the digging efficiency was far less than before.

Its eyes showed a look of despair, knowing that it had lost the possibility of escaping, the hydra hurriedly lay on the ground like pushing a golden mountain and a jade pillar, revealing a surrendered appearance.

Ning Bizhen naturally couldn't see it, and the eyes of the hydra lying on the ground showed a cruel look.

The Hydra is very intelligent and cunning, and if it is only a temporary contract, it is likely to betray its master, and even fight back at a critical moment.

"Kill!"

Ning Bizhen knew the habits of the hydra very well, even if the hydra had a lot of value, she didn't have the idea of planting a bomb next to her, not to mention that the value of the dead hydra was not very low.

It's better to be dead, it's a hundred!

The Hydra raised its head in horror, and the last thing it saw was a colorful glow of energy, directly drowning it.

Roar~Roar~

Ning Bizhen's demon pets unleashed two long-range attacks in a row, and in the colorful energy tide, the voice of the hydra became weaker and weaker.

Bang~

The passage shook violently, but under the action of the Cangxuan Dingdi Bead, it did not collapse, the nine-headed head of the hydra had been cut off, and the huge snake body was paralyzed on the ground, and there was no longer life.

After Hydra's death, Li Changsheng and Ning Bizhen began to disassemble Hydra's corpse.

Like the dragon, the hydra is also full of treasures, but the snake's blood does not have the quenching effect of the dragon's blood, and it does not have scale armor, and its value is not as high as the dragon's corpse, but the difference is not very big.

Li Changsheng mainly collects the blood, flesh and bones of the hydra, as long as they are purified into essence blood, I believe they can be sold for a very high price, not much worse than the hydra itself.

Even he even found a buyer, that is, Shen Haofei, who ranked fourth in the top 100 students of the university.

He has a superb six-headed snake, and the essence and blood of the hydra are naturally very important to him, and he has to buy it even if he goes bankrupt.

Shen Haofei is a fourth-grade fourth-order student of Tiandu Academy, and he will graduate in the first half of next year, and there is no possibility of any rival.

Only by selling resources to those who need them in need can they be sold at a high price.

After packing up, Li Changsheng let go of the map in his hand.

The map shimmered and flew towards the center of the pit.

The two followed the map to the center of the pit, where in addition to dirt and stones, there was also an inconspicuous stone slab.

This stone slab is about a zhang high, the whole body is gray, and there are four big characters written on it, and there is a faint groove at the bottom.

The shape and size of this groove is similar to the map of Tanoo Beppu.

Even if the hydra lives here all the year round and finds this stone slab, but there is no token to open, how can it open Danwang Beppu.

At this time, the map of Danwang Beppu fell lightly into the groove, which happened to fit perfectly with the groove of the slate.

The next moment, the ground shook slightly, and this anomaly did not last long, wisps of light emerged from the map of Danwang Beppu, and then filled the entire stone slab, especially the four big characters of 'Danwang Beppu' on the stone slab, which changed from inconspicuous to shining.

When the brilliance on the slate condensed to the limit, a white light shot out from the slate, and it continued to fall into the void beside it.

The void twisted violently, causing layers of ripples, gradually forming a spatial portal more than two meters high.

Li Changsheng grabbed Ning Bizhen's hand and stepped straight into the space portal.

Suddenly, the world was spinning, and by the time they reacted, the environment in front of them had changed greatly.

The two of them looked around, and found that they were standing on a small piece of land, only a few square kilometers in total, and it was even more barren, with almost no signs of life.

On all sides of the land, there is an endless darkness, with the occasional twinkling star and shooting star piercing through the darkness.

It's a starry sky!

Ning Bizhen looked left and right, and said in a deep voice: "This is a half-plane!"

The half-plane is similar to the ordinary plane, but only in a heterodimensional space of measurable size and finite pathways. Other planes are theoretically infinitely large, and a half-plane may only be a few hundred feet in size, and this half-plane is relatively large.

Theoretically, the half-plane can be artificially created, provided that humans can break through the dimensional space and open up a way to another plane.

Like the secret realm, the half-plane is also attached to the main plane, where oxygen naturally exists, which can be used for human survival.

The king of the demon master has the power to break through the space, this half-plane, since this is Danwang Beppu, this half-plane is naturally related to Danwang.

In this half-plane, there stands a magnificent courtyard, which is also the only building in this half-plane.

The two of them came to the courtyard, which was quite spacious, with a plaque that read 'Danwang Beppu', and a lifelike gilt statue of a human figure standing on either side of the gate.

Li Changsheng recognized this statue, which was the statue of Dan King Chen Mohe.

Squeak~

Li Changsheng pushed open the rusty gate, and a puff of dust flew up, the period when King Dan was active was hundreds of years away from now.

It has not been taken care of for hundreds of years, and this courtyard looks very old and dilapidated, and there are no prohibitions.

The two did not stop, but went directly into the courtyard and began to look at the surrounding environment.

The courtyard has a total of five rooms, namely a bedroom, an alchemy room, a Dan Pavilion, a kitchen, and a reception room.

For the first time, the two came to the nearest alchemy room, which was probably also the place where the pills were placed.

In this alchemy room, the first thing that catches your eye is an alchemy furnace with a height of two feet, engraved with a statue of Zhurong, with nine orifices on it, and the whole body is emerald green, and I don't know what kind of material it is made of.

"Huh!"

Li Changsheng touched it, and he suddenly wondered, because he could feel the heat of the alchemy furnace, this was the first alchemy furnace in hundreds of years, how could it still preserve the heat.

Ning Bizhen hurriedly asked with concern, "What's wrong?"

"This alchemy furnace is a bit weird!"

Li Changsheng did not hide it, carefully opened the lid of the alchemy furnace, and found that there was a blazing flame inside the alchemy furnace.

This flame can be said to be inconspicuous, very similar to ordinary flames, but through the feedback of spiritual power, Li Changsheng can clearly feel that this flame contains powerful energy.

"Bi Zhen, what is this?"

Compared with Li Changsheng, Ning Bizhen's insight is naturally better.

At this time, Ning Bizhen on the side thought for a while, and then seemed to think of something, and said, "This must be an unquenchable fire!"

Unquenchable fire: Alien fire, which contains the rules of unquenchable fire, is known as a flame that will never be extinguished. If the fire pet absorbs the unquenchable fire, the fire skill burn probability of the demon pet is doubled, and at the same time, it can greatly increase the burning time of the flame, forming secondary damage to the enemy. Note: Non-fire demon pets are not allowed to be devoured!

"Unquenchable fire!" After learning that this was an unquenchable fire, Li Changsheng instantly became excited.

Alien fires are very rare, and they are closely related to the rules of fire in this heaven and earth, and have all kinds of strange effects.

If this unquenchable fire is absorbed, the strength of the fire demon pet will definitely be improved, and it can break through the realm with the help of different fires.

Li Changsheng said tentatively: "Bi Zhen, why don't you let your three-legged fire crow absorb this immortal ......?"

"I can't take it!"

Without waiting for Li Changsheng to finish speaking, Ning Bizhen shook her head like a rattle and directly chose to refuse.

"The Immortal Flame is too precious, not to mention that you also have a Blazing Bird, allowing it to absorb it can also enhance your strength!"

"Okay, but if there's anything else that works for you, don't say no!"

Seeing Ning Bizhen's resolute appearance, Li Changsheng had no choice but to accept the entire alchemy furnace.

As for the Immortal Fire, now was not the time, and he was going to wait until he became a Fourth-Order Demon Master before letting the Blazing Bird take it, hoping that it would become a Boss-level Demon Pet.

In addition to the alchemy furnace, there was also a large cabinet in the alchemy room, on which were placed a dazzling array of jade bottles, which were covered with dust.

For hundreds of years, even if this place was once forbidden by King Dan, it has long been wiped out by time.

Ning Bizhen flicked his sleeves, and a breeze blew, directly rolling up the dust on it, and he didn't know where to go.

Li Changsheng casually picked up a jade bottle, and after opening the cork, he smelled an unpleasant smell.

Just like food spoils, pills also have a shelf life, but the shelf life varies depending on the category.

Li Changsheng poured it, and as a result, a gray-black substance was poured out, accompanied by an even stronger unpleasant smell, obviously this bottle of elixir had deteriorated.

In the following time, Li Changsheng experimented one by one, but unfortunately the age interval was too long, hundreds of years, almost all the pills here deteriorated, even if there were no spoiled pills occasionally, Li Changsheng did not dare to take them immediately, and they had to be tested.

After collecting several bottles of pills that didn't seem to have deteriorated, Li Changsheng took Ning Bizhen and left the alchemy room.

The two searched, and there was nothing of value in the kitchen and living room, but Danfang Pavilion was very rewarding.

As the name suggests, the Tankata Pavilion is the attic where various Danfang are stored.

King Dan is famous for his alchemy, and he naturally has a large collection of Danfang, many of which are still rare or even unique Danfang.

In the process of inspecting all kinds of pills, when Li Changsheng saw one of the pills, his hands couldn't help but tremble, and his face showed excitement.
