………………

As soon as the three Black Water Yin Fox Kings died, the remaining Black Water Yin Foxes suddenly lost their backbone and swarmed like headless flies. They no longer had the momentum that had started to surround Nie Yun.

Take advantage of his illness and kill him!

With a thought in his heart, he summoned the black flames from the space in his body, and then one man and one snake rushed towards the remaining black water fox in front of him.

………………

At this moment, Nie Yun didn't need to deliberately use "Seven Kills with the Wind Sword". Every time he swung the Wind Shadow Sword in his hand, the sharp sword energy escaping from the blade could kill all the black water foxes within a radius of ten meters. kill!

Countless system prompts came one after another in Nie Yun's mind. Not long after, all the remaining fox groups in the huge blood palace formation were wiped out by this man and the python again.

"The stock of 'Rejuvenation Pill' is running low, so you have to use it sparingly."

Nie Yun's spiritual consciousness penetrated into the space within his body to count the remaining quantities of various elixirs, and he suddenly smiled in his heart: "However, since the quality cannot be improved, then use the quantity to increase it. Wouldn't the effect be the same?"

Thinking of this, Nie Yun did not take the remaining "Rejuvenation Pill", but took out a large handful of "Super Qi Replenishing Pill" from the space in his body, stuffed it all into his mouth, and recovered The spiritual power lost in the Dantian.

"As the saying goes, we share blessings and share hardships."

Nie Yun turned his head and looked at Hei Yan, whose head was as big as a bison. He smiled maliciously and said, "Open your mouth."

When Hei Yan reluctantly opened his terrifying mouth that could hold a carriage, a stench mixed with the smell of blood hit his face.

After smelling this stench, Nie Yun almost vomited out last night's dinner.

"Shut your mouth, you are so disgusting!"

Nie Yun took out five or six "Super Qi Replenishing Pills" from the space in his body and threw them into Hei Yan's bloody mouth. He patted Hei Yan's huge, hard and cold head with his palm, frowned and said:

"Hurry up and restore your spiritual power. Otherwise, if the "Soul Transformation Powder" outside the formation dissipates, then it will be much more difficult than now if we use "Monkey King Honey" to lure the Black Water Yin Fox over for hunting. ”

At this moment, there is one person and one python. To outsiders, he is just a young man in ragged clothes. His hand is caressing the head of a black python that is twenty stories high.

Any scale of the giant python was bigger than the young man's head, especially this terrifying giant python that seemed to choose anyone to eat at any time. It actually nodded frequently under the young man's touch and seemed to be enjoying it.

Such a weird and disharmonious scene was happening right in front of me. If any outsiders saw this scene, their jaws would drop in shock!

………………

Not long after, the spiritual power in one person and one python returned to its peak state.

Nie Yun looked up, and with a thought, an entrance several feet wide slowly appeared on the edge of the blood palace formation.

At this moment, outside the entrance, most of the originally gathered group of black water foxes had dispersed. Only a hundred or so of them were deeply poisoned by the "Soul Transformation Powder" and were already lying on the ground unable to move, waiting to die.

The remaining black water foxes are actually not very powerful, otherwise they would not be able to escape. In just a few seconds, all the black water foxes on the ground were captured by Nie Yunzhao.

"Now the "Human Soul Powder" in the underground secret passages has been absorbed by so many foxes and has dissipated to a negligible state. In about half an hour, all the "Human Soul Powder" in these passages will be dissipated Lost."

"We can no longer lure the beasts. Without the help of Soul Transformation, if we face a herd of this size, the benefits and risks will be completely unequal."

Nie Yun just took a brief look and saw the current state and situation of Huahunsan, and very wisely chose to stop immediately. Instead, he began to collect the souls of the black water foxes that he had slaughtered, and immediately began to make Huahun Powder again.

Nie Yun is confident in his own strength, but he is never arrogant.

He knew very well that without the help of this "Transformation Soul Powder", he would not have been able to hunt so easily among such a large number of beasts, and still be unscathed in the end.

"It's a pity that I don't have suitable soul materials on my body. I can't refine special soul treasures to collect souls. I can only use secret methods to collect souls one by one. The efficiency of this is really low, and these The souls are collected, and if they are not made into "Soul Powder" as soon as possible, they will dissipate in a short time."

Thinking of this, lightning suddenly flashed in Nie Yun's mind.

"That's not right, I have ready-made materials!"

Where are the materials?

Nie Yun turned his head and looked at the corpse of a green water python that was hundreds of meters long, his eyes flickering:

"This green water Yin python has already reached the level of the Martial Emperor. It has been cultivating beside the Ghost Saint for countless years. Even now that its body has long since decayed, leaving only dilapidated corpses, it is still an extremely precious existence!"

"This is a rare and high-quality material! Although it does not practice the Soul Dao itself, it has been cultivating next to the Ghost Saint for such a long time. Under the subtle influence of the whole body, it is already extremely compatible with the Soul Dao. , it can be regarded as a quasi-soul dao material."

"Let me think about what kind of spiritual treasure is more suitable for refining. It should collect souls, store souls, be easy to refine, and preferably have some other functions, such as being able to assist Nie Yun in fighting... "

Nie Yun's consciousness sank into his inherited memory. After searching around, he found a spiritual treasure that completely met all his requirements - the Ten Thousand Soul Banner!

This is a spiritual treasure that is famous in the world of cultivation and can only be used by pure demonic monks.

The reason why Nie Yun chose this spiritual treasure was that it was very practical, had a large storage space and was extremely simple to refine. Moreover, the souls collected in it can be released to assist oneself in fighting when necessary to make up for one's own shortcomings in group attack.

In addition to this, there is another factor. It is Nie Yun who has a Nahuo flag in his hand. Nie Yun only needs to erase the formation in it, then use it as the main body, and then add materials for refining. This can save a lot of steps and greatly increase the success rate of refining.

After thinking about it, Nie Yun immediately took action.

He walked up to the Green Water Yin Python, searched carefully, and finally selected a relatively complete corpse.

The corpse was completely black, about one foot long, and as thick as an arm. I held it in my hand and weighed it, and it felt like it had the right weight.

"Okay, it's decided that you will be the flagpole!"

"As for the flag."

Nie Yun was thinking in his heart, and then he thought about it, weren't the three black water Yin fox kings just right?

They feed on Yin Qi, which is the same Yin thing as the Green Water Yin Python, and they also suck the Yin Qi produced after dissipating from the Crystal Core of the Green Water Yin Python.

Although these black water Yin foxes are no match for the Soul Dao, they are not repelled by the aura of the Blue Water Yin python. At the same time, this is also the best material Nie Yun can find now.

He walked into the pile of corpses, found all the corpses of the fox kings, and then carefully peeled off all their skins with the Wind Shadow Knife.

"Okay, everything is ready, just the last step of refining is left!"

Although the process of refining the Ten Thousand Soul Banner is simple, there is still one final problem before Nie Yun. That was his level of weapon refining. He was still at the entry level until now. There was definitely no way to refine the Ten Thousand Soul Banner at this level.

But how could Nie Yun not think of this?

Glancing at the system panel, I saw that my points had already exceeded one million, reaching a total of 1.49 million!

"System, I want to refine the Ten Thousand Soul Banner. What level of weapon refining skills should I exchange for?"

Nie Yun whispered in his heart.

【Ding! 】

["Ten Thousand Soul Banners": Xuan level spiritual treasure. 】

[Note: If the host wants to refine it, it needs to exchange for the peak level "Item Refining Technique" to succeed! 】

[The peak level "Item Refining Technique" is priced at 600,000 points. Do you want to redeem it? 】

"Fuck, it's such a stupid system, why don't you go and rob it?"

Hearing the price, Nie Yun almost gasped and cursed in his heart.
