"Powerful power, also accompanied by hidden drawbacks, this kind of thing, we can't advise the public, the reason why we will improve the strength without restrictions, because ........."

"Damn, it's gone at the critical moment!"

The handwriting in this paragraph was covered by blood, and Yu scolded loudly, and his mood was not very stable.

Lu Xinghe patted him on the shoulder, didn't say anything, but turned the page and continued to read.

"The birth of this project is to be able to combine the gods with the human body to create a creature that transcends all things, and we call it Satan, but unfortunately for thousands of years, we have not succeeded in completing this work in the true sense of the word, which can help our race return to the top, because the human body cannot be perfectly integrated with the gods. ”

"Until a few days ago, we found a cave in the underworld, and the aura there was actually perfectly balanced with the power of our "Satan", and the experiment was about to be completed, hahaha, this is the project we have been waiting for for a thousand years. ”

"Human experiments!?create creatures!?these brutes!" Yu angrily threw the document to Lu Xinghe, not wanting to read it anymore, "You put it away, go back and hand it to the team leader." ”

Lu Xinghe also gave up, nodded, carefully put away the document, and put it in the Qiankun bag.

According to the above, then it is very likely that they were killed by this "Satan", and of course it is also possible that someone came to snatch something and killed all the people here. Yu calmed down and analyzed.

Lu Xinghe nodded in agreement: "But no matter what, this 'Satan' is gone, for us, there is no harm for the time being, but the premise is that we still have the harvest, and that document can at least let us know what they have done............"

"Who'!!"

A strange aura fluctuation made Yu suddenly turn his head and look in the direction of the underground passage vigilantly, but what made him strange was why he didn't notice it just now?

Bang Bang Bang!

Probably in his thirties, a man with a thin sword at his waist stepped out of the shadows, and the Skyfire Empire's costume clearly symbolized his belonging.

And under the short hedgehog head, his heroic face was full of pleasure, and his smile was mixed with a hint of insidiousness, and his tone was very cold, as if he could kill people between words.

"Interesting, the strength of the martial spirit master level can detect my movements, are you from other empires?"

"Tsk..."

Yu smacked his tongue, a drop of sweat slowly slipped down his forehead, for the mysterious man who suddenly arrived in front of him, he couldn't see through it completely, his strength was at least above the martial spirit, if he wanted to compare, only Ye Bai and the elders would give him this kind of oppressive feeling.

"Put the documents away and go..."Yu glanced at Lu Xinghe's position and said in a low voice.

"What about you?"

"Don't talk nonsense, you only have three seconds, give me all the spiritual power, run!"

The last word fell from his mouth, and the black and dark gold Tang knife had already been pulled out and rushed towards the mysterious man, and Lu Xinghe also circled the man's blind spot at this time, rushing towards the position above the underground passage.

"It's really two impatient people, didn't your parents teach you to respect people?" The mysterious man stood in place and glanced at Lu Xinghe slightly, and then slowly walked forward.

"Hmph, one sword Shura! Ten Thousand Blades Return to the Sect!!"

Yu's figure turned into a straight line, and above the mid-air of the dark gold Tang knife, the wood attribute ability was fully opened, and tens of thousands of Tang knives had already locked the mysterious man in all directions.

"Let's go!"

With a sigh of understanding, Lu Xinghe didn't think much about it, obeyed the order and took the opportunity to slip onto the passage, extremely fast, and then rushed out of the fortress in a few blinks of an eye.

And Yu had already thrown a lonely fight, and used the spiritual power of his whole body to pour into the dark gold Tang knife, and suddenly, the dark golden light was sheng.

"Artifact?? ”

The mysterious man smiled, and at the same time, tens of thousands of blades, and the sword Shura who had defeated Akabane, bombarded his body at the same time.

Boom!!!

The wind and waves were exhausted, and the shattered underground research room had disappeared from its original appearance due to the sudden outbreak of fluctuations, and the powerful blade qi almost collapsed the underground.

"Whew...... Call...... Call......... Damn!"

Yu gasped, his aura had run out of oil at this time, but he couldn't guess how strong this man was.

He raised his head, his eyes fixed on the mysterious man who caught him with a sword between his fingers, and at that moment just now, he clearly saw how fast this guy in front of him drew his sword.

In all directions, every Tang knife was slashed down by its incomparably accurate slash, a whole ten thousand, indicating that at that moment, this person swung the sword at least ten thousand times, and also perfectly collected the sword, and completely wiped out all its blades directly, this unbelievably powerful, where is this person sacred?

"Have you had enough?"

Yu didn't speak, trying to pull the sword out of the mysterious man's hand, but no matter how much force he used, it didn't have any effect, as if the knife was set between those fingers.

"You created the 10,000 blades with strong wood attributes just now, curser. The mysterious man smiled and pushed back the dark gold Tang knife that he wanted to retract.

This made Yu staggered back two steps, but this action still made him ask suspiciously.

"Who are you, and why don't you kill us with your strength?"

When the mysterious man heard this, he laughed and said, "I am not related to you, I am not enmity, why did I kill you?"

"That's true, but aren't you from the Heavenly Fire Empire?" Yu Shenyi glanced at his body and said.

"You said this, I just snatched it from some unlucky bastard, and you really think I'm from some kind of Heaven-Breaking Fire Empire?" the mysterious man asked rhetorically, which made Yu even more confused.

"Then why did you come to the Imperial Institute? ”

"Of course, I won't tell you the reason, hahahaha, but I don't care what contradictions there are between you and the Skyfire Empire, let alone what I do to you. ”

Yu was speechless, he was really not from the Heavenly Fire Empire? He glanced at the mysterious man twice in disbelief, and immediately prepared to catch up with Lu Xinghe.

"Wait, ...... Cursed"

Yu was stopped, but he frowned, he was very unhappy with the title of cursed.

"My name is Yu. ”

"Huh...... So, you just created your own knife technique?"

"That's right, what's wrong?" Yu asked.

"It's interesting, you can create such a powerful spiritual skill by yourself, but it's just a spiritual skill with a body but no soul......"

"Uh-huh???"

The mysterious man did not answer Yu's confusion, and still said to himself: "The will is not firm, as well as the inner confusion and confusion...... "The essence of chaos is that it cannot drive great power, let alone choose anything", this is how your knife confided in me. ”

"........." Yu looked at the dark gold Tang knife suspiciously, and then looked at the mysterious man, but the figure with the hedgehog head had already disappeared.

Yu hurriedly looked around and searched for the figure, but found nothing, "Strange person." ”

"We'll see you again. The mysterious man's voice suddenly echoed in the underground space.

Yu didn't think much about it, this guy's strength was too strong, and it was even worse than the feeling of depression that the third elder gave him.

The strangeness of the personality of a person of this strength is beyond his comprehension.

His feet were turbulent, and he took out an elixir from his bosom and left the ground.

At this moment, Lu Xinghe had already entered the Hals Mountains, but he was not sure of Yu's life or death now, but he could confirm that the strength of that mysterious man must be extremely terrifying.

He didn't stop at his feet, and all he could do was hand over the "Satanic Plan" document to the Order.
