"What the hell is this made of? It's so hard and so resilient. ”

Tu Niu Niu exclaimed, Tu Tiantian on the side also looked like a ghost, the Ziwei Sword Star Fall that the two of them slashed together turned out to be just like this.

"I'll try. ”

Zhen Kana stepped forward, and the flames around him suddenly exploded, as if the whole person was bathed in flames, and the black fog floating around him was directly avoided from afar, blooming with light.

Then, he threw a punch, and a huge fist shadow formed, like magma condensed.

The foreign object also sensed the threat, and quickly dodged to the side, but the Magma Fire Fist followed directly as if it could track it.

Bang...

The flames exploded, as if the red-hot stove had suddenly burst open, sparks splashed everywhere, and where the fire fist fell, a huge fire pit burned out, burning flames.

Then, one by one, all four of them froze.

The foreign body changed again, and only a pair of black viscous substance like soft clay remained, constantly changing shape, and finally turned into a small black sword.

The small sword was formed, and a powerful sword intent suddenly burst out, sweeping the heavens and the earth, everyone couldn't help but bow their heads, and they couldn't help but have a thought in their hearts, in front of this sword intent, everything was an ant-like existence.

Not only that, but the soul has been greatly affected, as if in the face of such an existence, they are willing to sacrifice their souls, and this is the supreme glory.

Spooky moment, however, suddenly someone moved.

Yiheng held the red thunderball in his hand, and slapped the black sword with one palm, which was also a release of the small magic technique.

The little black sword seemed to have a spirit, looking at the thunderball that was flying towards it rapidly, and suddenly turned around and fled, so fast that it disappeared in the blink of an eye.

At the same time, that powerful sword intent also dissipated like that, disappearing without a trace.

Tu Niu Niu, Tu Tiantian, and Zhen Kana were all covered in cold sweat, and they were almost about to leave their bodies just now.

The three of them looked at each other, not understanding what the situation was, and they all looked at Yiheng.

"It should be some kind of evil spirit, which can affect people's minds and amplify emotions, I have encountered it before. ”

Yiheng explained that he had seen it before when he devoured the Blood Melting Fruit, but it was much weaker than the little black sword explosion.

In the distance, Han Qianxue and the mysterious princess walked up, and the princess, who had never spoken, suddenly spoke, her voice hoarse.

"I didn't expect that between the four foreign objects, there was still a sword spirit hidden. The god of the gods is really determined, and the old body just now is planted. ”

Where is Yiheng's firm mind, but it was the black coffin that helped him dispel the evil qi, so it was not affected.

"Does the old woman know what it is?" Yiheng asked as he changed the subject, and everyone also looked at the mysterious princess.

Wang Po bowed up and looked at the dim sky, felt the cold wind blade, and tapped the ground under her feet with the ghost staff in her hand, and explained.

"A sword moat, the power of the domain, even if ten thousand years have passed, the sword intent has not completely dissipated. The sword intent that broke out just now should be a trace of sword intent from the God Refining Emperor at that time. ”

A trace of sword intent turned out to be such a terrifying coercion, and it was hard to imagine how powerful the sword from 10,000 years ago should be.

"However, this sword intent has already been corroded by Yin Qi, contaminated by evil qi and given birth to demon spirits. That little black sword is no longer a spirit weapon, but a brake weapon. ”

Wang Po half-squinted, and her words gave people a feeling that the little black sword was easily untouchable.

The Evil Weapon will infect the mind that is being used, and will eventually turn the wielder into a bloodthirsty soul-devouring being, and if it does not have a powerful mind that absolutely crushes the soul of the Evil Weapon, it cannot be controlled at all.

"If I'm not mistaken, that little black sword was made by the sword intent absorbing the Immortal Flowing Iron, right?" Yiheng looked at everyone, and there was an excited light in his eyes.

There is no yang flow iron, the unique iron of the Yin Wind Abyss, and only the dark abyss of the dark sky can produce this kind of iron.

Pure black, unshaped, non-yang flow iron is a kind of flowing iron, which can change its form with the mind, and is an excellent supplement to iron for casting weapons.

"Is that the Yangliu Iron?, so there must be this kind of iron around here?" asked Tu Niu Niu excitedly, glancing around.

"There should be, our destination is already ahead, so let's recharge here. ”

Han Qianxue said softly, her face was pale, and she looked a little weaker than before: "If anyone digs up more Yangliu Iron, I hope they can sell me some." ”

"Let's dig it!"

There was a treasure underground, and the four of them glanced at each other, and they immediately moved.

Yiheng took the Supreme Spirit Soldier in his hand and began to look around, but in the end he didn't find any special location, and there were the same small stones everywhere.

Naturally, only the stone monster was more likely to come into contact with the Yangliu Iron, and the little black sword was hidden in its body.

With this inference, Yiheng found the pile of stones that the stone monster popped out of before, and began to dig a pit.

Everyone found a spot they liked and started digging, but they dug for a whole day and found nothing. But the next day, it was different.

"Hey, little brother of the gods, have you found anything?"

Tu Niu Niu suddenly came up, looked at Yiheng in the deep pit and roared, with a smug smile on his face.

"Hey, you're digging fast, hahaha, and sure enough, you're also using storage to transport soil. I just dug up a pound, but there are impurities in it. ”

After saying that, Tu Niu Niu turned around and left again, but showed off elsewhere.

Yiheng was a little speechless when he heard this, but he was not discouraged, the spirit of the evil weapon chose to live here, it must not be so simple, and he would definitely gain something if he dug deeper.

One day, two days...... Five days have passed in a blink of an eye, Han Qianxue and the old woman are busy with their business, which is very mysterious, and Yiheng and they are also busy digging treasures.

"Hey, I found a crack that seemed to contain the residue of non-yang flow iron. The sound of slaughtering cattle came from the depths of the earth again.

Yiheng was not a little surprised, because there was also a crack under his feet, and the little black snake had already entered it.

Although he hadn't dug anything in the past few days, he was getting more and more excited, which showed that the piece he had dug had been absorbed by the little black sword, so he was in the right direction.

"I have to be good, how can this be empty down here? Hey, I saw a swift black shadow. ”

Soon, Tu Niu Niu yelled again, and then, Tu Tiantian and Zhen Kana also spoke, and they also saw a black shadow.

"It turned out to be a little black snake. ”

Tu Niu Niu seemed to have gone deeper underground, and suddenly roared loudly, followed by a loud noise, as if he had moved his hands.

"Brother Shenming, don't be kind, that little snake ran away to you, you raised it!"

Tu Niu yelled, then jumped out of the pit to the ground, and hurried to the entrance of Yiheng Cave. And almost at the same time, Tu Tiantian and Zhen Kana also came.

"I said, what are you looking at me like this?" Yiheng hurriedly jumped to the ground, looked at the three of them and sneered, "It can't eat much." ”

"It's not that you can't eat much, it's that you don't have any leftovers. Zhen Kana said calmly, and then spread out his palms, "Divide." ”

"What is this snake? Why do you have such a big appetite?"

Tu Niu Niu was not in a hurry to ask for no yang flow iron, but looked at the little black snake on Yiheng's shoulder curiously, looking strange.

Hearing that there was a snake, the mysterious princess also rushed over as soon as possible, and after seeing the little black snake clearly, she was shocked: "Xiaoyou, where did you get it? Can you sell it?"

The little black snake suddenly arched up, and the snake letter sprang out, with a fierce look. Yiheng hurriedly comforted him, this old woman was very mysterious, but she couldn't be provoked, and maybe he still had to ask the other party.

"Not for sale. Yiheng said categorically, "However, it seems that Wang Po knows what it is?"

"A little bit of it. Wang Po looked at the little black snake, her eyes bloomed with black light, and she said faintly, "With it, you will definitely become the enemy of the dragon clan, so it is better to sell it to me and refine it." ”

"The seniors laughed, if you don't want to talk about it, skip this topic. Yiheng said with a cold face, trying to suppress the anger in his heart.

"The old body is also for your good, and I think you have also discovered that it is extremely sensitive to the things of the dragon clan. Wang Po did not give up and continued to persuade.

"You don't have to worry about it, with me, no one can hurt it. Yiheng touched the little black snake's head and comforted it not to worry.

"Xiaoyou is really ignorant and fearless, this snake is called the Nether Dragon Shadow. It's a snake, but it feeds on dragons, how can the dragon clan allow it to exist like this?"

Wang Po looked at Yiheng, as if she was questioning, and as if she was admonishing.

"All things in heaven and earth, there is a way to exist, and the way of heaven can tolerate it, even if it is a dragon clan, it is not qualified not to tolerate it. ”

Yiheng looked serious, this is his reason.

"It's such a big breath, then I can only wish Xiao Youyun luck. The princess shook her head, and turned to leave.

"Wait. Yiheng suddenly called out to Wang Po and asked, "Do you know what the soul bound spirit is?"

"Oh, why are you asking this?" Wang Po suddenly turned around and stared at Yiheng carefully, but she didn't find any aura like a yin ghost on Yiheng's body.

"If you can, please let me know, Miss Han doesn't want Yang Flow Iron, you can exchange it for it. Yiheng looked at Han Qianxue and asked for advice.

"Mrs. Wang?" Han Qianxue shouted softly, obviously she wanted to be without Yang Liutie, and the purpose of their trip had not yet been achieved, and they still needed Yiheng's help, so there was no need to stiffen the relationship.

"Ask what it is, do you want it?" Wang Po looked at Yiheng after being silent for a while, and asked.

"Yes. ”

Yiheng replied, about the soul binding, he looked through many ancient books, and the records he found were related to the ghost path.

"A spiritual object refined by a secret method is used to forcibly control the soul, and I can refine the soul with the soul binding spirit, in exchange for ten catties of non-yang flow iron. ”

The old woman smiled, her wrinkles were all squinted together, and when the words fell, she added: "Be pure." ”

"Then I have to wait until I go back to find Master Zhu Yitai Zhu to refine. ”

Yiheng replied, but he was still a little distressed, a pound can buy 50,000 yuan of crystals of non-yang flow iron, and Wang Po actually opened his mouth to be ten catties.

"No, you are too underestimating the Nether Shadow Dragon, even dragons can eat it, so naturally it is very easy to refine and purify the Yang-free Flowing Iron. Wang Po looked at the little black snake and said.

"Xiao Hei, take as much as you take, spit it out. Yiheng looked at the little black snake, touched its head, and said seriously.

The little black snake obediently spat out a large pile of black mud mixed with various stones and dirt, and then spit out a cloud of black gas to envelop it. After a while, there is only pure viscous black mud left, which is no yang flow iron.

"Well, it's all resting, let me serve you. Tu Niu Niu rubbed a pair of big hands, stepped forward excitedly, and then took out a large basket of iron boxes and began to collect.

"One catty, two catties ......" Tu Niu Niu counted excitedly, and finally there were thirty boxes in it.

"Can't you take some bigger props?" Looking at the small iron boxes, Yiheng couldn't help but bury a sentence, "Thirty catties, I'll take ten catties, and how about the three of you divide the remaining twenty catties?"
