Yu Fei stared coldly at the middle-aged man, and the aura fluctuations in front of him continued to rage around his body. The middle-aged man felt the aura fluctuations emanating from Yu Fei's body, and he was not weaker than himself at all, and with the fact that his own subordinates provoked Yu Fei just now, I am afraid that today's things will not be good! Just as the middle-aged man's mind was constantly changing, Yu Fei's voice slowly sounded.

"Say it, how do you want to die?" Yu Fei's cold voice sounded in the ears of the late-stage Golden Immortal powerhouse like a demon god from hell, and when he heard this voice, the late-stage Golden Immortal powerhouse trembled violently in his heart, unable to speak.

Looking at Yu Fei's expression, the middle-aged man frowned, if the black boss joined forces with him, even if he was afraid that he would not be able to get out today. The middle-aged man was extremely unwilling, but things had developed to such a point that even if he was ten thousand unwilling, there was nothing he could do. The middle-aged man's expression changed for a while, and he saw two streamers flashing on his hand, and as soon as those two streamers appeared, they exuded a strong aura fluctuation.

Immediately after, the two streamers flew in front of Yu Fei, and Yu Fei directly reached out to catch the two streamers. As soon as I started, I felt an extremely surging aura fluctuation from the two streamers. Looking at the two beads in his hand that were slightly smaller than his fists, Yu Fei was slightly surprised in his heart, these two beads turned out to be two sixth-order immortal beast spirit cores! You know, Yu Fei once wanted to buy the sixth-order immortal beast spirit core and inlay it into his god-killing martial arts, but it was simply priceless!

With the growth of his current strength, the ordinary fifth-order immortal beast spirit core can't keep up with his own consumption at all, and the power of the arrow he shoots is also extremely limited, and there is only a little bit of power with the crystal long arrow, but in the explosive state, it is only the level of the late immortal, and the number is extremely limited. But right now, these two sixth-order immortal beast spirit cores are tantamount to sending charcoal in the snow for Yu Fei, and the sixth-order immortal beast spirit cores are very valuable, if they really want to sell, I am afraid that they will reach millions of spirit stones and a sixth-order immortal beast spirit core.

If these two sixth-order immortal beast spirit cores were embedded on the Divine Killing Martial Arts, I am afraid that the power of the Divine Killing Martial would almost double, and it could be regarded as adding a talisman to himself in the next spiritual energy tide. Yu Fei received the two fairy beasts into his ring, which was regarded as accepting the middle-aged man's apology. When the middle-aged man saw Yu Fei accept the immortal beast spirit core, he didn't care about the pain, hugged his hand, and quickly retreated with his clansmen. At this time, his heart was dripping blood, and he regretted coming so recklessly, he really lost his wife and lost his soldiers! Two sixth-order immortal beast spirit cores, even if he got his hands on it, it would take a lot of effort!

After the middle-aged man left, the black boss came to Yu Fei's side excitedly, took out a bead with strong wind attribute aura fluctuations from the ring on his hand and handed it to Yu Fei, laughing and said, "This brother, you did me a lot of help just now! I also have one here, I will give it to you directly!"

Feeling the aura fluctuations emitted by the six immortal beast spirit cores that the black boss stuffed into his hands, Yu Fei was slightly shocked in his heart, this fairy beast spirit core was much more powerful than the two fairy beast spirit cores that the middle-aged man had paid for him just now!

Just when Yu Fei was about to excuse himself, he heard the voice of the black boss, hugged Yu Fei's shoulders intimately, and slapped his chest thumping: "Brother, if you refuse, don't blame me for turning my face!

Hearing the words of the black boss, Yu Fei showed a wry smile on his face, this black boss is really hospitable! Seeing that the black boss insisted, Yu Fei was not polite, and received the sixth-order immortal beast spirit core into his ring, seeing Yu Fei's movements, the black boss nodded with satisfaction, and he was happy with a mouthful of big white teeth.

After Yu Fei received the two sixth-order immortal beast spirit cores into the ring, Yu Fei turned his head to look at the black boss on the side and asked, "Brother Hei, brother has something unknown! I wonder if Brother Hei can tell me one or two?"

When the black boss heard Yu Fei's words, he grinned, and a solemn expression appeared on his originally smiling face, and said, "Brother wants to ask about the aura tide, right?"

Yu Fei nodded, he believed that this black boss had been here longer than himself, and that he had lived in the Spirit Beast Forest, so maybe he should know some clues about this.

Seeing Yu Fei nodding, the black boss continued: "Brother, it's not that the elder brother lied to you, and I don't know much about the spiritual energy tide! However, it is said that when the spiritual energy tide erupted, someone saw it from a distance, and it was the appearance of a palace! It is very likely that it is the Demon Emperor Hall used by the Demon Emperor in the past!"

"Demon Emperor Palace?" Hearing the words of the black boss, Yu Fei showed a puzzled look on his face.

Seeing Yu Fei's puzzled expression, the black boss continued: "According to legend, this Demon Emperor Hall is a super-level immortal weapon, but because it is too mysterious, no one knows what this Demon Emperor Hall looks like!"

The puzzled look on Yu Fei's face was even stronger, even if the Demon Emperor Hall was a super-level immortal weapon, it was impossible to have such a strong aura, even if it was completely constructed of aura, it was simply impossible! Yu Fei faintly felt that this matter was probably not that simple!

"Brother, listen to my advice!It's best not to get close to the Demon Emperor Palace!" Saying this, the solemn expression on the black boss's face became even stronger.

"Why?"

"According to legend, the Demon Emperor Hall has given birth to an extremely terrifying instrument spirit, and the strength of that instrument spirit is probably not below the Yuan Heaven Immortal, and even surpasses the cultivation of the Yuan Heaven Immortal!"

Just when Yu Fei doubted the truth of the news, Li Lao's voice sounded from the bottom of Yu Fei's heart: "Little guy! If that thing is really the Demon Emperor Palace, maybe it really has such terrifying strength! Because, that Demon Emperor Palace is a treasure that was once lost in the Cloud Sea! And the most terrifying thing about the Demon Emperor Palace is that it can store a large amount of spiritual energy, so much that you can't imagine!"

The lost treasure in the sea of clouds and mist? Yu Fei's heart was flooded with turbulent waves, and a wave of excitement surged up, it was the first time he had heard of the immortal weapon that could store spiritual energy!
