Hearing this, Yu Changqing was startled at first, and hurriedly used his divine sense to explore the surroundings, and found that there were no reinforcements from other demon clans, and he suddenly wondered why this demon clan had found him and said these words.

But on the surface, Yu Changqing pretended to be domineering, and said in a skeptical tone: "That kind of sword from five thousand years ago actually has something to do with my old husband?

"What? don't you believe it?" The red-haired man also saw the suspicion in Yu Changqing's eyes, so he said jokingly.

After speaking, I saw the red-haired man's laughter even louder.

On the other hand, Yu Changqing's face was slightly angry, and he said: "Hmph! Then you have to tell the old man what it has to do with the old man!"

The red-haired man showed a hint of sarcasm on his face, and sneered:

"Dead old man, do you know that the dragon-shaped beast you just dealt with is the sword spirit nine-colored glass dragon of the phantom glass sword, if the sword spirit is destroyed, the phantom glass sword hidden in the empty song mountain is an ordinary glazed sword!"

"Phantom Glass Sword Spirit, what does that have to do with the old man?" Yu Changqing's eyes showed a hint of disdain.

On the surface, Yu Changqing deliberately pretended to show the red-haired man, but in fact, he was secretly thinking about the credibility of what the demon clan said.

And it was even related to the battle between humans and demons five thousand years ago, and he actually said that the two people who defeated the Demon Venerable and the seven demon generals at the beginning were completely because of the merits of the two divine swords.

Yu Changqing is skeptical about this matter, he can't believe everything, but he can't disbelieve it has always been his style of doing things.

However, he was even more puzzled as to why this demon clan, who was also one of the inheritors of the seven demon generals of the demon race, wanted to inform him about this.

At this time, I saw the red-haired man speak again: "In that battle, we were completely defeated, and we even had no power to fight back, and we lost eight leaders, including the Demon Venerable!"

"But some of our demon soldiers escaped back to the demon domain by luck, and the people in our demon clan are very tall and mighty, all of them are brave and good at fighting, and they have never known the word "fear"!"

"But at that time, when they fled back to the Demon Domain, they were all full of fear in their eyes, as if they had seen something extremely terrifying!"

After saying this, the red-haired man suddenly stopped, showed a strange smile, looked up at Yu Changqing, his eyes were full of strange colors, and said:

"Why don't you guess what those demon soldiers saw that would make them so scared?"

Yu Changqing didn't answer the red-haired man, only stared at the red-haired man, and said coldly, "What do you mean?"

The red-haired man smiled and continued, "Two divine swords flew into the sky and turned into two giant beasts, one was a glass dragon that emitted a nine-colored glow, and the other was a strange-looking beast wrapped in purple thunder and lightning!"

"Whenever a demon touches two of these two giant beasts, or is hit by the magical powers of these two giant beasts, it will immediately turn into a pool of black ash.

"Even the demon generals of the tens of thousands of years of seven-vein inheritance of the demon clan joined forces to last a pillar of incense in front of these two giant beasts, and in the end, they ended up like other demons!"

"It was also the original Demon Venerable Lan Yu who relied on the Demon Clan's Supreme Treasure Silent Demon Sword to barely survive the attack of the two giant beasts, but in the end, he was still killed by the two divine swords penetrating his body at the same time!"

"This is everything back then, if it weren't for those two swords, everything that happened to our demons would have happened to your human race!"
