Refining the Shen Yuan Spear requires six main materials, among which the 10,000-year-old cold iron stone Lei Yu can be replaced with the thousand-year-old cold iron stone bought in the Lishui Pavilion, although it can't play the maximum role, but it is enough The blood spirit stone can be replaced by the blood spirit knife, as a Dan soldier, I am afraid it is better to use the blood spirit knife instead than using the blood spirit stone.

As for the thousand-year-old blood jade and the treasure house of the Purple Spirit Ice Monarch family, there is no need to worry. And although the Black Evil Stone was not available for a while, Jun Wuxian got some news of the Black Evil Stone, as long as he looked for it carefully, he may not be able to find it.

Only the last thing, Yin Yuan Jin, does not know the whereabouts, no one knows where the real Yin Yuan Jin of Lu Dao is, even Jun Wuxian can't know. Because the Yin Yuan Gold is too precious, it has not appeared for many years, and it is rumored that the Yin Yuan Gold has long been exhausted, and there is no Yin Yuan Gold on the Thunder Continent at all, and there is only a small existence in the starry sky of the universe.

Therefore, this is the last item, Yin Yuan Jin, which has become the key to Lei Yu's refining of the Shen Yuan Spear. If you can't find Yin Yuan Jin, even if you put together the other five things, it won't be of much use, and you won't be able to refine the Shen Yuan Spear at the end.

"Lei Yu, you wait here for a while, and I'll go back immediately and bring the thousand-year-old blood jade and purple spirit ice. ”

Jun Wuxian said, and didn't wait for Lei Yu to speak, the breeze blew, and he drifted away, nowhere to be found.

"This old boy is still in such a hurry. However, boy, you don't have to worry too much, Jun Wuxian has always been affectionate, since he promised to hand over the thousand-year-old blood jade and purple ice to you, he will definitely do it, you just wait!

Yin Ming said, as a friend who has been friends with Jun Wuxian for tens of thousands of years, he naturally understands Jun Wuxian's temperament.

"Senior, I'm not worried about this, but I'm thinking about the whereabouts of Yin Yuan Jin. Now, the four main materials have been collected, and the Black Evil Stone has also been found, leaving the most important material, Yin Yuan Gold. If there is no Yin Yuan Jin, everything is in vain. ”

Lei Yu said, with a solemn expression on his face.

"You're right. However, the boat is naturally straight to the bridge, you don't have to worry too much, you can also see that we have collected five main materials, only one is missing, it is impossible to fall under the last one material. ”

Yin Ming reassured, but there was also a hint of uncertainty in his tone.

Yin Yuan Jin, this material still existed in ancient times, it is a Yin attribute metal, but with the passage of time, there is also the mining of cultivators, the amount of Yin Yuan Gold has been very small, and there has been no news of Yin Yuan Gold in the last thousands of years, it is very likely that Yin Yuan Gold has been extinct in the Thunder Continent, and Yin Yuan Gold can no longer be found.

If this is really the case, Lei Yu's previous plan will be completely ruined, and the Abyss Spear will not be able to be successfully refined, which is undoubtedly a huge blow to Lei Yu.

Hearing Yin Ming's words, Lei Yu's mood also eased a little, even if he wanted to get Yin Yuan Jin now, he had to calm down, after all, Yin Yuan Jin did not appear for no reason, and he still needed to look for it slowly.

Lei Yu calmed down and crossed his knees on the ground, since fantasy is useless, it is better to recover his strength and wait until he goes to find Yin Yuan Jin by himself in the future.

Suddenly, this barren mountain was quiet again, Lei Yu and Yin Ming did not speak, each thinking about it, waiting for Jun Wuxian to return.

A quarter of an hour later, a fresh breeze emerged again, and a moment later, Jun Wuxian's tall figure reappeared in the barren mountains.

Lei Yu has been waiting for a long time. ”

Jun Wuxian had a smile on his face, standing on top of the barren mountain, giving people a very close feeling, making people unconsciously have a good feeling, and he couldn't see his true face at all, he was actually one of the ten demon kings of the Hell Demon Sect, the Desperate Demon King.

"Senpai, you're here. ”

Lei Yu opened his eyes, he didn't expect Jun Wuxian to come back so quickly. It's just that considering the cultivation of the other party's Immortal Thunder Stage, even if the clone in front of him is only the cultivation of the Thunder Infant Stage, this distance is nothing to him at all.

"Well, I've been looking for it in the treasure house for a while, but fortunately, the thousand-year-old blood jade and the purple spirit ice are still there, so I brought these two things with me. ”

Two space bags appeared in Jun Wuxian's hands, and with a wave of his hand, in a moment, this space bag floated in front of Lei Yu.

"Thank you, senior!"

Lei Yu had a smile on his face, and took the two space bags, just now Jun Wuxian agreed, but now he really got the thousand-year-old blood jade and purple spirit ice, this feeling is naturally a little different, which makes Lei Yu a little excited.

Shen Nian didn't enter a space bag, the materials in it were all auxiliary materials, Lei Yu just glanced at it, and after making sure that there was no problem, he put away this space bag.

Then, Lei Yu's gaze fell on the second space bag, and his divine thoughts entered it, and he immediately saw the situation in the space bag. This is a small space with a radius of about ten zhang, which is not worth mentioning at all. It's just that Lei Yu didn't dare to take it lightly, and his breathing became a little nervous. This was the place where two important materials were placed, and he naturally didn't dare to underestimate it.

In this space, there are two areas, each with two things. In Lei Yu's mind, these two places were probably the places where the thousand-year-old blood jade and purple ice were placed.

As expected, Lei Yu's divine thoughts continued to go deep into the space bag, and in the first area, Lei Yu found a blood-red rock, very irregular, about hundreds of catties in weight, the whole body was blood-red, as if it was bleeding, and there was a very heavy evil qi surrounding this rock.

"This is a thousand-year-old blood jade!"

Lei Yu said in surprise, this is not a thousand-year-old blood jade, just a spirit stone that breeds a thousand-year-old blood jade. However, even so, Lei Yu was still very excited, this was a whole thousand-year-old blood jade, which could maintain the effect of the thousand-year-old blood jade to the greatest extent possible and increase the success rate of refining the Abyss Spear.

"As long as I open this thousand-year-old blood jade stone and take out the thousand-year-old blood jade inside when refining, I will be able to obtain the most effective thousand-year-old blood jade, which will be of great benefit to my refining of the Abyss Spear. ”

Lei Yu muttered in his heart, and his face couldn't help but have some excitement.

The thousand-year-old blood jade is the carrier of the thousand-year-old blood jade, and it is very rare to have such a large thousand-year-old blood jade, and it is even more rare as a refining material.

After calming down his mood a little, Lei Yu's divine thoughts poured into the second area again. I saw a purple ice cube lying quietly in the second small area, about the size of an adult's fist, and the purple light flickered, very charming.

"Is this the Purple Ice?"

Lei Yu was a little surprised, compared to that thousand-year-old blood jade, this piece of purple ice was much smaller. It's just that Lei Yu soon found that this piece of purple ice was a little different, and the cold aura emanating from his whole body made Lei Yu feel a chill.

This cold is not cold on the surface, but seems to be able to freeze the soul and has supreme power. Lei Yu was sure that even if he didn't use this piece of Purple Ice to refine the Abyss Spear, this piece of Purple Ice alone could become a very powerful Thunder Soldier, and it would be no problem to kill the opponent.

"I now kind of understand why my predecessors separated these two materials into two areas. Lei Yu said softly, feeling the cold aura emitted by the purple ice and the evil aura emitted by the thousand-year-old blood jade, Lei Yu found that these two breaths were not compatible at all, if these two things were put together, I am afraid that there would be unexpected effects, and the biggest possibility was that the two things were destroyed together, and it would not be good at that time.

"Xie Lu, senior, this is really a bit unexpected for me. ”

Lei Yu said sincerely, a few drops of Lei Yuan liquid were exchanged for such a precious refining material, this is simply a bargain, Lei Yu is a little unsure of what to say, thinking that Jun Wuxian also really wants Lei Yu to refine the Abyss Spear.

"No thanks, these are the things I should do. You are the master of the Hell Demon Sect, and you have the heavy responsibility of recovering the Hell Demon Sect on your shoulders. I'm no longer the Demon King of Despair, but I'll definitely help if I can. ”

Jun Wuxian said with some emotion, the former Desperate Demon King is no longer there, and there is only one Jun family ancestor left, but the regret in Jun Wuxian's heart has never disappeared, and he is still a little worried about the demise of the Hell Demon Sect, and now he only hopes that Lei Yu can revive the prestige of the Hell Demon Sect.

Yin Ming approached Jun Wuxian's side and silently patted Jun Wuxian's shoulder. Although he didn't speak, Yin Ming completely understood Jun Wuxian's mind. Jun Wuxian turned his head and smiled at Yin Ming, everything was silent.

"By the way, Lei Yu, I seem to have found some clues about the Yin Yuan Jin you mentioned. At this time, Jun Wuxian seemed to think of something and patted his head.

"What, senior, did you really find out the whereabouts of Yin Yuan Jin?"

Lei Yu asked in surprise, if he really found Yin Yuan Jin, then Lei Yu could start preparing for refining the Shen Yuan Spear, and he didn't have to go through such a hard time to find materials.

"Jun Wuxian, I know that the Yin Yuan Gold of the Dao has almost been mined, are you sure that you can find the Yin Yuan Gold?"

Yin Ming asked with some doubts, in the era of the Hell Demon Sect, Yin Yuan Jin was no longer common, and now that 100,000 years have passed, it is even more difficult to find Yin Yuan Jin, and he is not sure if what Jun Wuxian said is true.

Jun Wuxian nodded and didn't speak, but there was an affirmation on his face. Apparently, he was not lying.

"Great, as long as I find the Black Demon Stone and Yin Yuan Gold, I can immediately return to the Zixiao Sect to refine the Abyss Spear. ”

Lei Yu said excitedly, he was already a little impatient to get the Yin Yuan Gold.

"Lei Yu, you don't have to be too excited. Although I have found some clues about Yin Yuan Jin, I am not very sure, so you have to calm down and don't rely on me without discovering Yin Yuan Jin by then. ”

Jun Wuxian said, calming Lei Yu's excited mood again.

Jun Wuxian was right, the amount of Yin Yuan Jin was too scarce, and Jun Wuxian didn't dare to be sure. It would not be good if the bamboo basket was empty at that time.

"Senior, where is the Yin Yuan Gold? Whether there is Yin Yuan Gold or not, I will go there. Lei Yu said firmly, for the sake of Yin Yuan Jin, even if the place Jun Wuxian said was the Longtan Tiger's Den, he would have to break through.

"It's not anywhere else, it's in the hands of the Yunzhou Nangong family. Jun Wuxian smiled slightly, somewhat satisfied with Lei Yu's performance.

"Nangong family?" Lei Yu was slightly stunned, but he remembered someone in his heart, and his thoughts couldn't help but drift into the distance.
