Jiang Yi and the Heavenly Phoenix Emperor's inference was correct, the Immortal Gu did possess a great magical power that could roughly probe the area where Jiang Yi was!

This magical power is the unique skill of the Emperor of the Hades, and it has only been passed on to the Underworld, and as long as any human race, demon race, and the Hades have been locked in the breath, they can explore the area where he is through this secret technique.

However, this secret technique is flawed, or the Immortal Ancient has not reached the realm of the Immortal Emperor. If it was the Emperor of the Underworld, he would be able to find Jiang Yi in an instant, but the Immortal Gu couldn't do it, he could only sense Jiang Yi in the nearby area. So he mobilized a large army to search carefully within a radius of thousands of miles, and at this moment he also arrived at the nearby interface, the Celestial Realm!

He has mobilized tens of millions of royal clans, tens of millions of underworlds, surrounded thousands of miles in a radius, and is still mobilizing large armies.

All the secret realms in the vicinity were being searched over and over again, and he gave a death order to find Jiang Yi and the others, because... He recognized Chihong!

The appearance of the soul of the Fire Dragon Sword means that the Fire Dragon Sword has also been born. The Fire Dragon Sword must be taken no matter who it is, not because the Immortal Gu wants this sword, but because this sword cannot fall into the hands of the human race. The appeal of this sword is too great, it is the representative of the Emperor of Heaven, and it can command the heroes of the world.

The Underworld doesn't even care about the Tiangang Realm and the Heavenly Spirit Realm, if the Qing Emperor wants to lead the troops to bring down these two interfaces, he will definitely ignore it, and taking the Fire Dragon Sword can be worth a few interfaces, and when the Immortal Emperor is born, he can have an explanation.

With such an identity, of course he would not personally look for it, he sent out all the Hades Kings, but the eight Emperor Levels were not sent out, and he was going to take the eight Emperor Levels to besiege and kill them as soon as he found Jiang Yi and the others. Every other day, he would release the secret technique to make sure that Jiang Yi and the others did not leave.

Pity......

After reporting again and again, countless secret realms were searched but no trace of Jiang Yi and the others was found, and there were not even any clues.

He angrily ordered the army to continue to search, and any suspicious places could not be let go, all the underworld in the secret realm must be checked one by one, and he also ordered the tens of thousands of underworld in the nearby secret realm to be mobilized to the Celestial Elephant City, so that he could personally investigate and prevent Jiang Yi from lurking in the underworld.

......

Jiang Yi refined the flame for most of the day, and after making sure that his flame could support ten days and eight days, he asked the Heavenly Phoenix Emperor to teleport him out. The whole person of the Tianfeng Emperor turned into an ice sculpture, and his body was seriously frostbitten, if Jiang Yi came out half a day later, he was afraid that the Tianfeng Emperor would be frozen to death.

"Buzz!"

Putting the Tianfeng Emperor into the Heavenly Cold Pearl, Jiang Yi immediately retreated and cultivated, he chose the first path, continued to comprehend the mysteries of thunder and lightning, and took a few days to comprehend an ice mysteries that were too ethereal, or continue to comprehend the mysteries of thunder and lightning in a down-to-earth manner.

After a day of enlightenment, there was actually another Hades outside, Jiang Yi could only go in and hide, this time it was still an ordinary Hades, and he couldn't explore the cave at all.

After the Hades King finished exploring, Jiang Yi continued to come out to comprehend, but unfortunately this mystery was too cumbersome, he had been enlightened for so long, and he still felt that there was no end, and he felt that he could not comprehend in a short period of time.

"It's not going to go on like this..."

The time was too short, and Jiang Yi had a faint feeling that it was absolutely impossible for him to deduce the meaning of the thunder fire in just a few days, and even if he deduced the great success, he might not be able to control the source of the fire.

Seem... This road is also a dead end?

"Thunder makes fire, thunder can differentiate the five elements of gold, wood, water, fire, and earth, but it's a pity... Thunder can't make ice, and if he could, he would be able to absorb the source of ice easily, no—"

Jiang Yi's mind suddenly shook, how did ice form, isn't it made of water?

If he can get the Thunder Water into the door, then maybe he can resist this terrifying low temperature? Not to mention absorbing the source of ice, as long as he can get close to the source of ice, won't all problems be solved?

Derivation of the beginning and derivation of the Dacheng are completely different, the last time he deduced Lei Xinghuo only took a small half a day, and at this moment he has time completely.

"Good!"

Jiang Yi took a few deep breaths, calmed down his mood, and dispelled the distractions in his mind and settled down again. He began to comprehend from the beginning, starting from the thunder and lightning to differentiate the elements of gold, wood, water, fire, and earth, and he patiently gradually comprehended and deduced.

Time passed quickly, and this time Jiang Yi was lucky, and he didn't have the Hades King to investigate, but this time his progress was not as smooth as last time.

Maybe it was the last time he was in deep retreat, or maybe the last time he was inside the source of fire, and the last time he went very well. This time, he has been enlightened for a long time but has not yet started, and he doesn't care about anything, so he continues to meditate with his heart.

Half a day later, the Immortal Gu in the Celestial Elephant City was furious!

All the nearby underworld tribes were summoned to the Celestial Elephant City, and the Underworld personally explored without any problems, and all the secret realms were searched four or five times, but Jiang Yi and the others were not found, and no trace was found.

The secret technique passed down by the Emperor of the Underworld will never have a problem, and the Immortal Gu has personally tested it a few times without a problem. This shows that Jiang Yi and the others are indeed lurking nearby, and the reason why they are not found must be the incompetence of their subordinates.

He summoned those eight Emperor-level Hades Kings, combined all kinds of intelligence and information, and finally locked his eyes on more than eighty secret realms, and he decided to send these eight Emperor-level Hades Kings to personally explore these more than eighty secret realms.

More than 30 of these more than 80 secret realms are dead places, and the remaining more than 50 secret realms are relatively large, and the terrain is very complicated, he believes that Jiang Yi and the others are definitely lurking in these more than 80 secret realms.

The eight emperor-level Hades kings personally set off with their own armies, and the Hades Gu asked them to take the armies separately to explore these more than eighty secret realms and cross-explore, so that they would definitely not be left behind.

He still didn't go out himself, but sat in the Celestial Elephant City, the strength of these eight emperor-level was not much weaker than him, and the Immortal Gu believed that these eight Hades would definitely be able to find Jiang Yi and the others.

Coincidentally!

The first to explore the secret realm near the source of ice was Jiang Yi's old acquaintance Mingdi, because the secret realm of the source of ice was far away from the celestial realm, and there were still several secret realms to be explored in front of him, so when Mingdi arrived at the death place of the source of ice, it was already a day later.

The combat power of the Immortal is ranked second to last among the top ten emperor-level Hades kings, but the aura on his body is also very terrifying, the general Immortal King's aura can only probe the secret realm, and cannot spread to the bottom, but the aura of the Stygian can easily permeate below.

"Huh?"

When the aura of the underworld spread into the cave, he found some traces in the cave, the glacier inside obviously had traces of melting, although all of them were frozen at the moment, but it still felt that there were traces of man-made.

The strange thing is-

There was a deep pit in the cave that was melted out by flames, but at this moment, the pit was all frozen, the temperature inside was terrifyingly low, there was no flame at all, and Jiang Yi seemed to have evaporated in the world.

The temperature under the glacier is even lower, and the glacier here is so frozen that the aura of the underworld cannot penetrate it. After carefully probing a few times, he took the Immortal Qi back and immediately ordered: "Send a summons back to tell Lord Stydi, there is a problem in this dead place, please come over in person." ”

"Buzz!"

After the aura receded, a pair of eyes under the glacier suddenly opened, Jiang Yi was actually frozen by the glacier, there was no flame on his body, but his face was very ruddy, as if he was not afraid of the cold at all.

His body moved slightly, the glaciers around him cracked and cracked, and he grinned excitedly: "The sky will not kill me, thunder will give birth to water, aquatic ice, ice all things, I will no longer be afraid of the cold in the future, and the cold and heat will not invade......"
