Yin Yuan Jin, Yin Yuan Jin, which Lei Yu had been looking for for a long time, finally appeared, and his heart was naturally extremely excited.However, considering Xie Xinran's identity, Lei Yu's heart couldn't help but be conflicted, and he didn't know what to do.

Yin Yuan Gold must be obtained, but getting Yin Yuan Gold from Xie Xinran's body is another matter. Judging from Lei Yu's heart, he definitely didn't want to ruin Xie Xinran's affairs. However, refining the Shen Yuan Spear required Yin Yuan Jin, and for a while, Lei Yu was in a dilemma.

"Boy, don't think about it so much, since Nangong Ziyan ordered the Refining Hall to refine the Natal Thunder Soldier for Xie Xinran, and also announced the refining materials, this originally shows that Nangong Ziyan values Xie Xinran. Even if you take the Yin Yuan Gold away, Nangong Ziyan will definitely refine other natal thunder soldiers for Xie Xinran, so you don't have to worry. ”

Yin Ming comforted, he knew that Lei Yu had walked into a dead end, and only by letting Lei Yu's heart figure it out could he really make his own decision.

Hearing this, Lei Yu nodded, and his analysis was not unreasonable. Nangong Ziyan ordered the Refining Hall to refine the Natal Thunder Soldier for Xie Xinran, which in itself was an indication of attitude.

Moreover, she also announced the materials for refining the Natal Thunder Soldier, this attitude is even more worth mentioning, obviously the Nangong family's attention to Xie Xinran has reached an extreme, even if he takes the Yin Yuan Gold this time, Nangong Ziyan will definitely refine a Natal Thunder Soldier for Xie Xinran.

Therefore, he is not very worried about Xie Xinran. Xie Xinran's genius must have been discovered, and the Nangong family didn't pay attention to it, and even the marriage with the Xiao family was abandoned, it is conceivable that Xie Xinran will definitely become the mainstay of the Nangong family in the future.

"Well, that's the only chance. If you miss this time, I'm afraid you won't get the Yin Yuan Gold again. ”

Lei Yu made a decision, the Yin Yuan Gold was too precious, and it was possible that this Yin Yuan Gold of the Nangong Family was the last piece of Yin Yuan Gold on the Thunder Continent. If you can't get this piece of Yin Yuan Gold, the Shen Yuan Spear will no longer be able to be refined.

"It's good that you figure it out, although Xie Xinran is your woman, you can also compensate her in other ways in the future. However, Yin Yuan Gold is different, you must get it, otherwise, you will not want to refine the Abyss Spear successfully. ”

Lei Yu figured it out, Yin Yin was naturally excited, the Shen Yuan Gun was the thunder soldier used by the Nine Shadows Emperor at the beginning, and he also wanted the Shen Yuan Gun to reappear in the world, reproduce the majesty of the Hell Demon Sect, and once again shock Yunzhou, and even the entire Thunder Continent.

Five days later, on a dark night, in the alchemy hall, a black shadow floated out of the room, quickly heading towards the depths of the Nangong family.

The Nangong family is very vast, and according to Lei Yu's understanding during this time, there are at least thousands of cultivators living in it, which is very huge. In this area, there are many places with formations, prohibitions, and strong defenses, and it is extremely difficult for outsiders to enter the Nangong family.

At this moment, Lei Yu turned into a shadow and walked among the Nangong family, slowly walking towards the depths of the Nangong family. He was dressed in black, with only two eyes on his face, and he walked silently, running in the heavenly palace of the Nangong family.

He walked very carefully, and he could only go a few miles in half an hour. In the past half an hour, he has encountered many patrols that have been strictly patrolling the Nangong family, and he has almost been discovered several times.

Fortunately, Lei Yu's strong body skills allowed him to evade the patrols of these patrol teams. It's just that since then, he has been more careful and doesn't dare to be careless. After all, this is the Nangong family, and once it is discovered, I am afraid that it will only end up in death.

"It's really well defended, it's only a few miles away, it's so tight, it seems that it will be difficult to reach the Refining Hall!"

Lei Yu stood on the roof of a temple, he was dressed in black, and there were several layers of forbidden places arranged around his body to ensure that he would not be discovered.

His divine thoughts felt the surroundings, and waves of thunder fluctuations surged, which was very complicated. Among them, some fluctuations were very powerful, much more powerful than Lei Yu's divine thoughts, and they were the aura emitted by the cultivators of the Lei Dan stage.

And for those temples with a powerful aura, Lei Yu wisely chose to avoid them, after all, compared to the Lei Dan stage cultivators, Lei Yu was still far behind.

Lei Yu restrained his breath and did not emit a single breath. And under the temple, a team of cultivators walked under this temple and did not notice the existence of Lei Yu.

Lei Yu secretly breathed a sigh of relief, the Nangong family is indeed a big family, and the guards in the mansion are extremely strict, even Lei Yu has to deal with it carefully.

"Go ahead, I'm going to investigate the situation in the Refining Hall tonight. If there is Yin Yuan Gold in the Refining Hall, take the Yin Yuan Gold directly. ”

Lei Yu made a decision, although the Nangong family was heavily guarded, but with the protection of several layers of prohibitions, Lei Yu believed that as long as there were no major mistakes, he would not be discovered.

The black shadow walked towards the depths of the Nangong family step by step, and every step was very cautious. An hour later, Lei Yu had already penetrated ten miles into the Nangong family, and at this moment, in front of Lei Yu, a huge palace-like building appeared in front of Lei Yu.

This is a majestic building, although it is deep in the dark, but the majestic momentum is still emanating, very remarkable, so that Lei Yu feels a sense of oppression.

Compared to the Alchemy Hall, the Alchemy Hall is the sky, and the Alchemy Hall is the earth. Lei Yu also finally understood why the Refining Hall was called a hall, and the Alchemy Hall could only be called a hall. Looking at the building in front of him, Lei Yu understood where the gap was.

Undoubtedly, the status of the Refining Hall in the Nangong family is much higher than that of the Alchemy Hall.

At the same time, the people who defend the Refining Hall are also much stronger than the Alchemy Hall, according to Lei Yu's understanding during this time, there is a strong man in the Refining Hall in the Lei Dan Period, named Nangong Yan, who is stationed in the Refining Hall all the year round, and is the number one master of the Refining Hall.

"What's going on? Why can't I feel the breath of a strong man in the Lei Dan stage?" Lei Yu hid in the shadows, observing this refining hall.

His divine thoughts radiated out, but he did not gain the slightest. This refining hall was empty, and no one existed. Not to mention a person, not even a cockroach, it can be said to be extremely simple.

All this made Lei Yu feel a little uneasy, this feeling was very peculiar, a few days ago, he also felt Nangong Yan's breath, but today he couldn't feel it.

Nangong Yan is not in the refining hall, and Lei Yu will not believe anything. According to Lei Yu's understanding, this Nangong Yan has been stationed in the Refining Hall for more than a hundred years, during which she rarely goes out, especially in the past ten years, Nangong Yan has never been out of the Refining Hall once, and regards the Refining Hall as her home.

Such a person would come out of the Refining Weapon Palace, Lei Yu didn't believe it at all. He felt as if the situation was a little different from what he had thought.

After observing for a long time, Lei Yu didn't find anything, he could only hear some insect chirping, and there was still no movement in the refining hall, only a thick darkness.

"No matter, I'll go into the refining hall and have a look. ”

Lei Yu made a decision, today he just came to investigate the situation, and he didn't want to alarm anyone, it didn't matter if he had gained anything or not, as long as he could get the situation of the Refining Palace.

Moreover, even if he was discovered by Nangong Yan, Lei Yu believed that he would be able to escape, because he had a domain platform given to him by Yin Yin in his hand, and as long as he activated the domain platform, he could easily leave the refining hall.

He retracted his breath and turned into a black shadow and quickly sank into the refining hall. In the blink of an eye, it disappeared very quickly.

"Is this the Refining Hall?" Lei Yu entered the Refining Hall and observed everything around him.

Lei Yu's first feeling was that the Refining Hall was very large, much larger than the Alchemy Hall, with a length and width of at least more than 100 zhang, which was almost comparable to a small square.

And in this space, it is divided into several areas, each area is a small refining hall, specially used to refine thunder soldiers, and there are earth fire gushing inside, emitting bursts of heat.

However, the flames were black, so there was no brilliance to be seen in the night. However, even so, Lei Yu did not dare to underestimate these earth fires, and the flames that could be used to refine thunder soldiers naturally had their own extraordinary.

At this moment, the refining hall was dark, swarthy, and unreal. It's just that all this is not the slightest obstacle for Lei Yu, and there is no difficulty for Lei Yu to see things secretly, and he can see every small refining hall clearly, and keep everything in his heart.

He was preparing to take away the Yin Yuan Gold in the future, and every place in the Refining Hall was carefully watched so that he could take the lead when refining the weapon.

"Is this the main refining hall?" Soon, Lei Yu finished observing the surrounding secondary refining halls and came to the largest main refining hall.

This main refining hall is much more than the other small refining halls, at least worthy of five small refining halls. Moreover, the color of the earth fire gushing underground was not black, but purple, but it was blocked by a small refining hall, so there was no trace of it outside at all.

"This is the Purple Flame Flowing Fire, one of the hottest flames on the Thunder Continent, no wonder it can become the Earth Fire in the Main Refining Hall. Lei Yu immediately knew what kind of flame it was.

The temperature of the Purple Flame Flame is extremely high, it is easy to melt hard materials, and it can remove impurities on the materials to the greatest extent, which is the best refining flame for refiners. The Nangong family was able to possess the Purple Flame Flowing Fire, no wonder they would attach so much importance to refining.

"Whew!"

A gust of wind blew, for no reason, very strange, but it made Lei Yu's heart feel a chill.

"Boy, didn't I warn you not to come again, and since you don't repent, don't blame me for being ruthless. ”

A cold voice sounded, mixed with a dangerous aura, that made Lei Yu's hairs stand up, and he knew that he had been discovered.
