However, a lot of refining materials have been collected.

Not all of the hundreds of stone chambers are as empty as Yang Kai’s first one investigated. Some stone chambers are piled with a lot of materials for refining tools. Most of these materials are ore and some strange things, which are all preserved year round without being damaged.

There are really a lot of numbers.

There are hundreds of stone chambers, even if there is only one-tenth of the things that Yang Kai collects, they should not be underestimated.

Yang Kai was not satisfied because the harvest was somewhat different from his expectations and was not as rich as he imagined.

However, after investigating along the way, Yang Kai discovered something that interested him, that was, the deeper the deeper the fire spirit gathered in the holes, the richer and more refined it was.

This is easy to understand. The lower the ground lung fire pool, the closer it is to the source of the fire pool. When he starts to refine Xuanyin Kui Water, he has to find the wall hole lined below.

Two days later, Yang Kai had already penetrated deep into the deepest part of the Earth Lung Fire Pool. At this deepest part, there were only two wall holes left without investigation.

The two wall holes were built in a deep location. At first glance, they were used for the most outstanding weapon refiners in the sect. One left and one right, not far apart. The entrance of the cave looked ordinary and had no novelty. However, since Yang Kai had seen the universe inside some wall holes, he knew that if he didn't look deep and carefully, he would never know if there was anything else in these wall holes.

Hopefully, she would find some discoveries. Yang Kai thought secretly, and casually found a hole on the left. His body swayed, shooting towards the hole like an arrow from the string.

The next moment, Yang Kai appeared in the wall hole passage. After standing firmly, he kept walking and continued to go deeper.

This wall hole was hundreds of feet deep. Yang Kai walked for a long time but still couldn't reach the end. While he was amazed, he became more and more excited. It was indeed the wall hole for the most outstanding weapon refiners in the sect. The depth of the construction seemed to be a little different, but I didn't know if there was anything good inside.

After walking forward for more than a hundred feet, a hint of white light suddenly came from the front. The light was soft and not dazzling. It even had some effects of calming the spirit and calming the soul. When Yang Kai saw this hint of white light, he felt his whole body relax and inexplicably felt a pleasant thought.

The speed under his feet was a little faster, and soon Yang Kai rushed into an extremely huge stone chamber.

This stone chamber is more than ten times larger than any of the hundreds of stone chambers he has investigated in the past two days, and the sky is dozens of feet high. I don’t know what exquisite methods have been arranged. Even though the stone chamber is deep in the ground, the air is still clear and there is no turbid feeling at all. This alone cannot be compared with other stone chambers.

Other stone chambers have a more or less a suffocating feeling.

And around the stone chamber, there are only eight white balls the size of fists, and the white light is emitted by these eight balls. Wherever the light passes, it has a magical and stable soul effect.

Yang Kai raised his eyebrows, and his eyes swept over the eight balls for a moment, then he placed his mind in the entire stone chamber.

However, after he had investigated this stone chamber, he felt extremely disappointed, and couldn't help but sigh. This stone chamber was built so magnificent and magnificent, and he thought that some good things must have been stored in it.

I don’t know that this stone chamber is like most stone chambers. There is nothing else except for a huge refining furnace in the middle.

The formation in the stone chamber is also still operating, extracting the most pure part of the firepower in the earth lung fire pool. It took tens of thousands of years to bake this huge furnace and cauldron, and it has never stopped.

When Yang Kai's eyes swept on the refining furnace, the buckwheat ground lit up and he grinned.

He found that the refining furnace was not damaged and was preserved in full!

He had found hundreds of refining furnaces in those stone chambers before, but no matter how high the grade or quality the refining furnaces were, they were scrapped and useless after tens of thousands of years of burning.

Among them, there are even many furnaces and cauldrons at the Void King level, which makes Yang Kai feel very distressed.

Now, he actually found a complete refining furnace here. No matter whether it is a coincidence or something, the quality of this refining furnace is definitely not low, and it must be a secret treasure of the virtual king level.

Only a refining furnace of this level can have the opportunity to preserve it.

While Yang Kai was happy, he quickly began to look for the control center of the stone interior formation.

Unlike other stone chambers where there is only one stone pier as the control center of the formation, there are four stone piers in this stone chamber, which really took Yang Kai a lot of effort to completely stop the entire formation.

He had never practiced the icy cold attribute technique, nor did he have a secret treasure of this attribute, so he could only wait for the temperature in the refining furnace to slowly emit.

About a day later, the red light on the refining furnace gradually restrained. Although it still looked extremely hot, Yang Kai was not weak in his own strength and was not afraid.

He quickly walked to the refining furnace, released his divine thoughts and found that as he guessed, this refining furnace was really at the virtual king level, but the grade was of such quality. He still couldn't judge for the time being, and it should not be lower than the mid-grade level of the virtual king level. The entire refining furnace is as high as five meters high. The same three-legged and two-ear style, unlike the refining furnace that Yang Kai had seen before, was not a dragon and phoenix pattern on it, but a whole strange bird.

Yang Kai looked around the refining furnace and found that he did not recognize the strange bird. It looked like a phoenix, but had a shadow of a crane. The bird's beak was long and its claws were powerful. It dragged three long tail feathers, and its body was elegant and beautiful. The feathers were carved vividly, looking vivid, as if it was about to rush out of the surface of the refining furnace.

Looking at it carefully, Yang Kai secretly recalled the classics he had read from Zong Ao, and when he was thinking about what kind of monster this strange bird was, his face suddenly changed, and his eyes narrowed to the eyes of the strange bird.

At that moment just now, Yang Kai felt like he was being peeped at by the other party.

But when he looked carefully, he found that the strange bird was exactly the same as before, without any hope, which surprised him very much.

However, with such an alert, Yang Kai did not dare to take it lightly anymore. Who knows if there is anything strange in the refining furnace? He kept releasing his mind and carefully checked the inside of the refining furnace. He confirmed that there was nothing else except a pool of burnt materials inside, and then he felt relieved.

This weapon refining furnace is a good thing, and you must not miss it. He cannot use such a huge furnace cauldron to refine alchemy. Since the holy essence in his body was transformed into demonic flames, Yang Kai no longer used holy essence in his alchemy, but used the power of the fire of his divine consciousness.

However, this thing can be brought back for Yang Yan to use. Although she has a stone puppet to help temper the materials, she still needs to use a refining furnace when she refining the secret treasure in the last step, shaping and engraving array.

Yang Yan helped him a lot, and these days he has been trying his best to set up formations for him and refine secret treasures. The two of them also enjoy the secrets of stone puppets and ethereal crystals at the same time. So even if the refining furnace in front of him is a secret treasure of the Void King level, Yang Kai would not be stingy to send it out.

After this decision, Yang Kai released his divine thoughts and wrapped the huge refining furnace. With the divine thoughts moving, he wanted to put it into the space ring.

At this moment, the mutated suddenly burst. The refining furnace, which had already cooled down, suddenly buzzed, and clusters of amazing flames appeared around the furnace cauldron. The flames were almost like a prairie fire, and they were burning towards Yang Kai's spiritual consciousness frantically.

Yang Kai was shocked and quickly took back his spiritual thoughts. This was the case. He suffered a loss. The release of the lyrics was burned to pieces in a short time.

Yang Kai was shocked with a pale face!

His spiritual consciousness possesses the magic of the fire of the spiritual consciousness, which is extremely hot. Even before discovering this earth lung fire pool, the heat of the fifth layer could not be destroyed so quickly. However, the flame bursting out from the furnace cauldron has such power. Wouldn't it mean that the flame is countless times more terrifying than the heat of the fifth layer?

Moreover, the flame was faintly filled with a sense of agility. After repelling Yang Kai's spiritual thought silk, the buckwheat flashed and disappeared again, as if everything just happened was just an illusion and did not happen.

Yang Kai naturally knew that it was not an illusion. He lost so much of his thoughts and had a split headache. How could it be an illusion?

Before he could figure out what was going on, the strange bird carved on the surface of the refining furnace suddenly came alive, and its elegant body flew out of the refining furnace and turned into an extremely beautiful red firebird. The amazing firepower was fiercely emitted from the strange bird. After just a little hovering, it shot directly at Yang Kai.

Yang Kai's face looked extremely ugly, and he exclaimed in a daze: "The weapon is so powerful!"

He immediately understood why the flame was so spiritual, and he understood that being peeped at by the monster bird just now was not an illusion, but a real thing. It was just that the other party was not a flesh and blood body, which made Yang Kai not able to notice.

This is actually a weapon spirit. The weapon spirit born from the refining furnace is not known to exist in itself or was slowly born after tens of thousands of years of burning the earth lung fire pool.

But when Yang Kai thought of this as a weapon spirit of a virtual king-level secret treasure, he became as big as a fight.

He has fought with many people and has also seen all kinds of high-end and low-end secret treasures, but no secret treasure has such a fierce weapon spirit.

Things like weapon spirits are extremely rare.
