The craziest upgrade system

Blood Palace, Black Throne, Nie Yun sits on it.

This kind of soul refining method is not an ordinary burden for Nie Yun now. This time, Nie Yun rested for two full hours before he regained his composure.

"This is the last step and the most critical step. Success or failure depends on this!"

Nie Yun whispered softly in his heart.

What he has to do now is to use the tempered soul essence to glue the flagpole and flag surface that have been separated and refined by Nie Yun to each other and make them into a whole.

This refining method is undoubtedly inferior. The best method is to directly refining the entire Ten Thousand Soul Banner during the refining process, so that the subsequent adhesion steps can be omitted. .

But there is no other way. A clever woman cannot make a meal without rice. In the final analysis, it is still Nie Yunqiong...

The previously refined flagpole and flag surface were laid flat on the ground. The flagpole and the body of the green water Yin python were integrated into the large flag in front of him now, and the flag surface was sewn together with the fur of the black water Yin fox. Therefore, the entire flag showed an infiltrating jet black color.

As Nie Yun took out a bottle of soul essence and slowly poured it on the connection between the flagpole and the flag, the soul essence fell on the connection like water, splashing with phantom-like fluorescence, and finally dissipated in the air.

At this time, an unexpected sight happened.

Under Nie Yun's gaze, these soul essences slowly moved around, as if consciously. Every time he moved an inch, he froze in place, and then spread outwards again.

One bottle, two bottles, three bottles...

After a while, the soul essence in his hand was used up. However, for now, only three bottles of soul essence are obviously not enough.

Nie Yun frowned slightly: "I only have three bottles of soul essence in my hand. At the current progress, at least ten bottles of soul essence are needed to completely connect this Ten Thousand Soul Banner. Once the refining process starts, there is no way to stop it. Even if I hunt down the black water foxes to collect their souls now, it’s too late..."

Now Nie Yun must find a way to solve this problem. Otherwise, at least the refining will fail and all resources and materials will be scrapped. At worst, it may even backfire on himself, and the gain will not be worth the loss.

Nie Yun quickly checked the inherited memories in his mind, trying to find a way to deal with it.

But unfortunately, the more Nie Yun looked up the inherited memories, the uglier his face became.

The ghost inheritance is the inheritance of the saint. It is almost omnipotent and covers thousands of things, but at this moment, there is no way to deal with it. It's not that the inheritance is not good, but that Nie Yun is too weak. He can't use most of the secret techniques at all!

In response to this situation, there are no less than a hundred ways to deal with it recorded in the ghosts. The simplest and most direct method is to directly set up a large formation to extract all the souls of all living creatures within ten miles and sacrifice them together with the unformed Ten Thousand Souls Banner. This will fill up the gaps in the remaining two bottles of soul essence.

But can Nie Yun use this method?

Nie Yun cannot use it.

Why? Is Nie Yun a bitch?

Because Nie Yun was too weak, he was unable to set up a formation that could cover a ten-mile radius.

What is now in front of Nie Yun is a dead end. No matter how hard he tries, the Ten Thousand Soul Banner and all the resources and materials refined this time are destined to be scrapped.

The wisest thing to do now is undoubtedly to stop immediately, give up all resources and materials, and protect yourself from backlash.

"My strength is still too weak. If I also had the strength of a saint, how could I be subject to such restrictions? I would directly sacrifice blood to all living beings within a radius of ten thousand miles, and by then this Ten Thousand Soul Banner will be accomplished!"

Nie Yun sighed in his heart, the phantom-like fluorescence reflected in those black eyes, but they looked more determined.

Obviously, Nie Yun doesn't want to give up!

Gradually, a crazy idea emerged in Nie Yun's mind.

He summoned Hei Yan from the space inside his body, and after whispering a few words to each other, Hei Yan's expression also looked very solemn.

Nie Yun's idea was very simple, which was to open the Blood Palace Formation again and use Monkey King Honey to lure the Blackwater Yin Foxes over.

The difference from before is that this time Nie Yun is collecting souls and at the same time, he is using all his strength to activate the Soul Cleansing Pond to refine the soul essence and add it to the Ten Thousand Soul Banner. This process will involve a lot of Nie Yun's mind.

In other words, Nie Yun had no way to free up his hands to help Hei Yan, and could only rely on Hei Yan to face tens of thousands of foxes on his own.

Once the black flames cannot withstand it, both the person and the python will suffer. Black flames will be seriously injured by the attacks of the foxes, and he himself will fail to refine all the materials, and will suffer backlash.

This time, it was different from before, because all the Soul Transformation Powder in Nie Yun's hand had been used up, and there was no soul for him to refine again. Without the restraint of Huahunsan, that is to say, the fox group this time is many times stronger than before!

Nie Yun activated the spiritual power in his body, and the ghostly spiritual power continued to gush out from his palms like spring water, and finally condensed into a pool about ten feet in size in the air - the Soul Cleansing Pond!

The Ten Thousand Souls Banner that is being adhered is located under the Soul Purifying Pond. With this arrangement, as long as the soul essence is refined out of the Soul Purifying Pond, it will drip on the Ten Thousand Souls Flag, and the refining process will not be interrupted. Break.

"Are you ready?"

Nie Yun looked at the huge Black Flame beside him.

Hei Yan did not speak, but silently nodded his carriage-sized head.

Nie Yun stuffed the remaining two hundred super qi-replenishing pills and half of the rejuvenation pills into Hei Yan's mouth from the space in his body.

"Go!"

As soon as he finished speaking, the Blood Palace Formation opened instantly, and the fragrance of Monkey King Honey appeared again.

Nie Yun maintained the operation of the soul purifying pool while staring closely at the entrance of the formation. It is impossible for him to let in all the tens of thousands of foxes outside at once. As long as the number reaches a certain level, he will immediately close the formation entrance.

....................................

A quarter of an hour later.

Corpses are everywhere.

Black Yan's ferocious and huge body has many claw marks, and many old wounds have some blood stains on them at this moment.

But fortunately, these are just minor injuries and nothing serious.

As long as the Black Water Yin Fox reaches adulthood, its strength can basically reach the second level, and only a few can reach the third level.

As for the fourth-level Black Water Yin Fox, also known as the Fox King, under Nie Yun's investigation, there were only three of them who died under Nie Yun before.

Logically speaking, as a fourth-level monster, Heiyan should be able to deal with these little scumbag foxes with ease!

This is indeed the case, but it is difficult for two fists to defeat four hands. If there are too many foxes, they will inevitably be injured.

It's not that Nie Yun has never thought about reducing the number of foxes entering the formation, but if he does this, the number of souls will be reduced, and the refined soul essence will not be enough to maintain the refining of the Ten Thousand Soul Banner.

"Hei Yan, can you still hold on? I'm going to let down a wave of foxes and come in."

Nie Yun glanced sideways, glanced at Hei Yan who was resting, and continued to focus on the soul purifying pool in front of him, refining the soul of the black water fox that had just been collected, and said softly.
