As the bronze plate said, this consciousness clone of the Lord of the Underworld is an excellent sparring partner. It is powerful, extremely experienced in combat, and understands the laws of space. The most important thing is that the battle with Xu Yang will be stopped in moderation and will not bring serious injuries to Xu Yang.

Looking at the bronze plate and putting away the mirage, Xu Yang was happy in his heart.

"Okay, next, I should also check the success of this plan, the harvest it brings!" Xu Yang landed on the ground, collecting treasures in the area where the corpses of the blue-eyed pterosaur, the Hell Xi Shizun, and King Jin Tai fell.

There are not many treasures on the body of the Hell Xi Shizun, and as a loyal elder of the Hades Clan, he naturally handed over the secret key to the Hell Stone Shizun and waited for the unified exchange of treasures. And on King Jin Tai's body, Xu Yang really found several treasures, among which there were even two drops of Shizun blood marrow!

"This is also strange, if King Jin Tai had taken the Shizun Blood Marrow beforehand, his injuries would definitely have recovered more quickly. Why did he delay and wait for the master of the underworld to exchange the wound medicine?" Xu Yang was a little puzzled. The blood marrow of the World Venerable is actually a treasure that greatly replenishes qi and blood and enhances life potential, if King Jin Tai had used it earlier, the injuries caused by the holy corpse to him would probably have healed long ago.

"What about people's hearts...... King Jin Tai probably felt that it was not worth it to use his own treasures to treat his injuries and then work for the underworld. Therefore, he would rather wait and let the Hades spend the key to exchange the treasure for him in order to achieve psychological balance...... It is estimated that the keys he obtained by himself were basically collected by the Stygian Stone. The obscene old man who was transformed into a bronze plate shook his head, quite emotional, which was very incompatible with his obscene atmosphere.

Xu Yang put away the blood marrow of the World-Honored One, put the rest of the useful items into the storage ring, and finally walked towards the huge body of the blue-eyed pterodactyl.

This is a real spirit beast, not those puppet spirit beasts constructed with the power of runes in the outer black palace. So. After the death of the blue-eyed pterodactyl, the corpse did not disappear.

"Tsk, this is a genuine spirit beast, and there are not many spirit beasts in the current Tianxuan World. Bronze plate sighed.

Under the prompting of the bronze plate, Xu Yang first collected the blood of the blue-eyed pterodactyl. Then the whole body is peeled off and calcined, and finally the flesh and bones are dismembered.

The spirit beast was full of treasures, and Xu Yang deliberately used two empty storage rings, one to store flesh and blood, and one to store treasure bones.

"The pair of eyes of the blue-eyed pterosaur are an excellent material for refining treasures, don't let it go. Looking at the pair of pupils as large as wheels on the bloody skull, the bronze plate reminded.

Xu Yang took off the eyes of the blue-eyed pterosaur as he said, and they were inside the skull of the blue-eyed pterosaur. But he found a soft white light!

"What is this, could it be the Inner Pill of the Blue-Eyed Pterodactyl?" Xu Yang held his breath, the quality of the Spirit Beast Inner Pill was very high, and it could even refine high-level holy medicine, and its value was immeasurable.

"How can it be so easy? Spirit beasts have spirits, and they often shatter Neidan at a moment before they die, and it won't be cheap for you. "The bronze plate is quite experienced, "I want to obtain the spirit beast Neidan." Unless you use overwhelming strength to completely control the spirit beast, and then slaughter it. However, people with this kind of strength are at least at the Saint Emperor level, and they don't look down on the spirit beast Neidan. ”

Sure enough. That soft white light was not some Neidan. Xu Yang probed his palm into the white light and grasped a cold object. He pulled it out and looked at it, but it was a secret key.

This key radiates a brilliant sheen, as if carved from a diamond. At the end of the key. There are four Venus. This logo, which represents this key, is a four-star key.

"It turns out that the secret key is hidden in the skull of the spirit beast, how did you put it in?" Xu Yang was a little puzzled.

"There are more means, and you can master the technique of distorting space, and you can do what you think is unthinkable. The obscene old man who had been transformed into a bronze plate shrugged and smiled, "Well, now, you're still too tender." ”

Xu Yang smiled helplessly and shook his head. Cultivating to a higher level, his vision is also one level higher, his current realm is not high, and he only has a preliminary understanding of the laws of space, and he has not even reached the level of "first glimpse", let alone the skills of distorting space.

And after Xu Yang got this four-star key, the illusion space also changed a lot. The original sky dome began to rumble and crack, revealing the cyan ceiling, and the plain under his feet was also fragmented, revealing the same cyan floor.

Almost instantly, the illusionary space of the Black Palace No. 54 completely collapsed. When the scene was frozen and Xu Yang looked around, he could only see four bronze walls and four light gates.

"I see, after killing the spirit beast and obtaining the secret key, the illusion space will automatically collapse. So...... The White House on the fifty-fiveth, has appeared?"

Xu Yang looked at the east wall, and sure enough, he found that the black light door on the wall slowly turned white.

"Okay, the matter here is over, let's take a look at what treasures there are in this underground palace, the largest No. 55 White House. ”

Xu Yang raised his feet and walked towards the light gate of the White House on the 55th.

In the Black Palace of the Thirty-fifth Dynasty, a group of elders of the Imperial Beast Clan gathered.

"Haven't found Elder Jin Taiwang yet?" said Jin Taixu, who was sitting in the center, with a gloomy face.

"Nope. I have sent a lot of messages to Elder King through the Transfiguration Array, but there has been no response. As for the sound worm, it was not handed over to Elder Jin Taiwang in the first place, and it was impossible to notify him. A Royal Beast Clan World Venerable next to him shook his head and sighed.

"This innermost Black Palace is so difficult to ......break through," Jin Taixu frowned and said, "With the strength of the old man, the black-backed flame dragon that touched the No. 45 Black Palace can only support the time of a stick of incense, and it is almost impossible to kill it." If Elder Jin Taiwang was here, the two of them might have a chance of winning together. ”

On the five-color stone square, King Jin Tai killed two Hades in a row, although it was Xu Yang who persecuted, but to a certain extent, the suspicion of the Royal Beast Clan against him was also dispelled a lot. Therefore, when Jin Taixu encountered difficulties, the first thing he thought of was King Jin Tai.

"Elder Jin Taixu, it's not a way to just wait. In the past few days, we have almost swept the outer black palace, and only the eight innermost black palaces can't gnaw down...... But the best treasure is in the White House of the Fifty-Five!" A Royal Beast Clan World Venerable shook his head and sighed, "If I knew this, I shouldn't have synthesized those three-star keys into a four-star key! I can't get to the White House of the Fifty-fifth at all, what's the use of the four-star key?" (To be continued, please search, better update and faster!)
