A stream of Nine Shadows Yellow Spring thunder qi emanated from Lei Yu's body. As soon as he approached the white mask, the white mask stepped back as if he had seen his master, not daring to make a mistake at all.

"Open!"

Lei Yu smiled slightly on his face and said softly.

As Lei Yu's voice fell, the white light mask trembled, and the white light became more dazzling, but then the white light receded like a tide, and in just a moment, the prohibition that was originally shrouded in the high platform dissipated.

This is a prohibition specially arranged by the Ice Devouring Demon King, and only the Nine Shadows Yellow Spring Thunder Qi can break it. Now, Lei Yu released the breath of the Nine Shadows Yellow Spring, and this prohibition was destroyed in an instant, without causing him any harm in the slightest.

The light faded, and the original scene was finally revealed on the high platform on the left. On the high platform, a gray pouch lay quietly on it, without the slightest thunder power fluctuation, like an ordinary pouch, but Lei Yu would not think so, this is the seal of the Ice Devouring Demon King, it is absolutely impossible to be so simple.

"It's a space bag, I wonder what's in the tunnel?"

Lei Yu's face showed a hint of curiosity, and he slowly walked into the high platform.

With his right hand stretched out, Lei Yu got the space bag without hindrance.

Playing with this space bag in his hand, Lei Yu's divine thoughts had already disappeared into the space bag. In an instant, a white light appeared in Lei Yu's divine thoughts, dazzling and accompanied by thick thunder fluctuations.

"What is this?"

Lei Yu gasped, and only when the white light disappeared did he see the scenery inside.

This is the light that countless Yin attribute thunder source stones bloomed from, dazzling, and a powerful thunder force fluctuated out, like a vast ocean, incomparably magnificent, immeasurable.

The internal space of this space bag is very large, about the size of a radius of several miles, and at a glance, it is full of dense Yin attribute thunder source stones, shining with silver light, full of an incomparable beauty.

"This is to empty a Yin Attribute Thunder Source Mine!"

Lei Yu sighed, there must be at least hundreds of millions of Yin Attribute Thunder Source Stones in this, except for Thunder Source Mine, it is impossible to have so many Yin Attribute Thunder Source Stones.

Shen Nian swept the space in the space bag, Lei Yu's face couldn't help but show excitement, these Lei Yuan Stones are all Yin Attribute Stones, and the level is very high, and the Thunder Power contained in them is also extremely strong, with the help of these Yin Attribute Thunder Source Stones, the Thunder Source Stones he needs for promotion in the future can be solved.

These Thunder Source Stones can at least support him to be promoted to the Thunder Infant Stage, which means that he doesn't have to worry about the strong Thunder Power in the future.

Moreover, not only that, but there are also some cold-attribute refining materials among these Yin-attribute Thunder Source Stones, which are all top-level materials, which will also be of great help to him in the future.

It can be said that the harvest on this first high platform has made Lei Yu ecstatic. Originally, he thought that the Ice Devouring Demon King would collect these Yin Attribute Thunder Source Stones in an extremely secret place, but he didn't expect to get these Thunder Source Stones so easily.

Lei Yu took out a Yin Attribute Thunder Source Stone from the space bag and held it in his hand, it was shining silver, which was more pure and easier to absorb than ordinary Thunder Source Stones.

A white light poured out from the Thunder Source Stone and entered Lei Yu's body, and a comfortable expression appeared on his face, as if he was about to ascend to the Immortal.

He cultivated the "Nine Shadows Yellow Spring Thunder", and if he wanted to be promoted, he had to have a large amount of Yin attribute thunder power. Now, these Lei Yuan Stones can be regarded as taking over his urgent needs, and cultivating in the future will definitely be twice the result with half the effort.

After a while, the Yin Attribute Thunder Source Stone in Lei Yu's hand began to slowly turn gray, and the thunder power conveyed was not as pure as before, after all, the thunder power contained in a Thunder Source Stone was limited, and it could not meet the huge needs of his body at all.

Lei Yu pinched his right hand, and the Lei Yuan Stone in his hand suddenly turned into a pile of powder, floating in the air. The thunder power in this Thunder Source Stone has been completely absorbed by Thunder Feather and has become a waste stone.

His eyes were on the other two platforms. This first high platform did not disappoint him, and the remaining two high platforms must not be ordinary either.

"Hehe, I'm more curious about the treasures on the remaining two high platforms now. ”

Muttering to himself, Lei Yu walked towards the high platform in the middle.

This high platform is also arranged with a layer of prohibition like the high platform on the left, but when Lei Yu approached, this layer of prohibition disappeared, and he didn't even need to say "break".

A trace of excitement appeared on Lei Yu's face, and a second treasure appeared in his eyes. It was a boxy brocade box, about the size of a palm, with a yellow thunder talisman attached to it, as if to suppress the treasure inside.

The thunder talisman was attached horizontally to the treasure box, very old, without the slightest spirituality, and it seemed that it could turn into ashes at any time.

This is an ancient thunder talisman, the rune on it Lei Yu does not know a word, it was pasted by the Ice Devouring Demon King himself, but after 100,000 years, this thunder talisman has also lost its efficacy, and it has no effect.

Lei Yu stretched out his hand and wiped it, the thunder talisman attached to the brocade box changed instantly, the yellowed paper couldn't withstand the impact of external force, just a little force, this thunder talisman dispersed like dust, silently, it was the strength of the years, and there was no trace left.

Even though this thunder talisman is extremely powerful, it can't resist the power of the years after all, and 100,000 years have passed, and everything has dispersed and dissipated in the dust.

Lei Yu did not hesitate, reached out and picked up the brocade box on the high platform, put it in his hand, and examined it carefully.

This brocade box is boxy, with a layer of crystal jade on it, but Lei Yu knows that this is not jade, but a material that is not gold or jade, and even he doesn't know it. However, since it was able to make the Ice Devourer King rush to load the seal, it was definitely not an ordinary product, and there must be something good.

There was a trace of curiosity in his eyes, and there was also a trace of excitement, and he had come to the extreme abyss with all his might, wasn't the purpose of obtaining the treasure? Now, the treasure was in front of him, and it seemed to be within reach, and Rao was a little excited about Lei Yu's mental cultivation.

It's really hard to get through the iron shoes!

"Smack!"

A crisp sound sounded, Lei Yu opened the brocade box, and in an instant, a brilliant light erupted from the brocade box, and a powerful thunder force fluctuation spread to all directions, which was quite terrifying, and Lei Yu could even feel a wonderful feeling from this thunder power fluctuation.

He couldn't say this feeling at all, it was like a person touching a realm that he couldn't reach, and it was absolutely impossible to feel this feeling without that realm.

Lei Yu's feeling is like this, there is a kind of "Dao" existence in that thunder power fluctuation, which seems to contain a trace of heaven and earth, mysterious and mysterious, unreasonable.

"What kind of elixir is this, and it has such a strong effect?"

Lei Yu's gaze looked into the brocade box, and a white elixir about the size of a dragon's eye appeared in his eyes.

A strong scent of elixir spread out, filling the entire secret room. At this moment, Lei Yu had a feeling of being transformed into an immortal, his body was extremely light, and even with his divine thoughts, he was promoted to a realm of extreme mystery.

It was just a spirit pill, and there was such a powerful feeling, Lei Yu's eyes were full of incredulity, and he stretched out his right hand gently, cautiously, not daring to disturb this spirit pill at all.

In an instant, Lei Yu took out this elixir from the brocade box and held it in his hand. Suddenly, a warm feeling arose from his hand and instantly flowed throughout his body, and a comfortable feeling arose from his body, almost making him want to moan.

This is a superb elixir, with incredible effects, much more powerful than all the elixirs that Lei Yu has seen, and only those powerful alchemists can refine it.

According to Lei Yu's estimate, if you want to refine such an elixir, you must at least cultivate in the Thunder Infant Stage, or even the Immortal Thunder Stage. Otherwise, it would not have been possible to have such a powerful effect.

Suddenly, Lei Yu's heart remembered some records of the Hell Demon Sect, and his face couldn't help but show a look of ecstasy. The Hell Demon Sect is not a sect that is good at alchemy, in the entire Hell Demon Sect, there are only a handful of elixirs that can be spoken, and one of them is similar to the elixir in front of him.

Nine Immortal Pills, which is a powerful and outrageous elixir. It is said that it is a spirit pill, but in fact it is not, this is the result of the formation of a part of the immortal thunder period powerhouse after forcibly breaking into the pill body, and the part of the cultivation of the immortal thunder period powerhouse is sealed in the pill body, which can be described as one of the strongest pills.

After taking the Nine Immortal Pill, you can get a part of the cultivation of the Immortal Thunder Stage powerhouse, and you can fight hard with the real Immortal Thunder Stage powerhouse for a period of time. Moreover, when the medicinal effect of the Nine Immortal Pill is lost, it will not affect the cultivator, and there will really be no side effects.

Moreover, since the Nine Immortal Pill contains a trace of the Immortal Thunder Stage powerhouse's perception of the law, the user can also take this opportunity to investigate the realm of the Immortal Thunder Stage powerhouse, which has great benefits for promoting the Immortal Thunder Period.

How could such an elixir not make Lei Yu excited, this must be the elixir refined by the Ice Devouring Demon King when he had a premonition that the general trend was gone, in order to leave it to the descendants of the Hell Demon Sect and recreate the past glory of the Hell Demon Sect.

You must know how precious the cultivation of a strong person in the Immortal Thunder Period is, if it is not necessary, the strong person in the Immortal Thunder Period will not easily make a move, after all, once the cultivation is lost, it will be difficult to make up for it, at least hundreds of years, or even thousands of years of penance. Although the Nine Immortal Pill was powerful, it had only appeared a few times during the years of the Hell Demon Sect.

It's just that no matter how powerful the pill is, it can't stand the consideration of time, although there is a blockade of the brocade box and the thunder talisman, but the Nine Immortal Pill still inevitably flows out a lot of essence, and the effectiveness is not as good as before, and even he can feel the mottled qi in the elixir.

This is the result of the erosion of the spirit pill, the powerful medicinal power of the Nine Immortal Pill was surrounded by the previous one, and Lei Yu couldn't detect it, but now that he returned to the basics, he felt it.

100,000 years is too long, and it is impossible for the Nine Immortal Pill to hold on, and the essence has dissipated a lot, and it has lost its previous efficacy. However, Lei Yu still did not take it lightly, even if the essence of the Nine Immortal Pill dissipated a lot, it was still a top-grade pill, which was not something he could bear now.
