Immediately, Li Yu looked at the holy beast in front of him with cold eyes, and said in an indifferent voice: "I don't know what the seniors mean by this?

He shook his head slightly, and then the Flame Monarch said, "I will abide by the bet, but your Heavenly Thunder True Qi, if you add my Heavenly Fire, the two of us can form Thunder Fire True Qi."

Before Li Yu could speak, the Flame King continued: "But because your Heavenly Thunder True Qi is guided down by yourself, and my Heavenly Fire True Qi is relying on external objects, so ......."

Thunder Fire True Qi, Li Yu was suddenly shocked in his heart, although he didn't know what kind of existence Thunder Fire True Qi was, but it must not be easy to be so valued by a tenth-level holy beast.

"Senior, is there a difference between what you said?", Li Yuqiang held back the question in his heart, and immediately asked, because he already felt that if he achieved the Thunder Fire True Qi at that time, it would be at least twice as powerful as the current Heavenly Thunder True Qi.

Nodding slightly, then the Flame Monarch said in a slightly helpless voice: "The difference is very big, if we all achieve Thunder Fire True Qi, then my Thunder Fire True Qi is the acquired Thunder Fire True Qi, and your Thunder Fire True Qi is the Innate Thunder Fire True Qi."

"Brother Flame, I've only heard that there were four true qi in ancient times, but this thunder fire true qi is the first heavenly fire, could it be that the thunder fire true qi is stronger than the four true qi?"

The Dark Demon Monarch also looked at the holy beast in front of him with a puzzled expression, after all, the four great true qi of the ancient times had long been a legend, especially the cave void true qi of the four true qi.

"That's just the ignorance of the world, in fact, the real four true qi of the ancients are not what you imagined, the true qi of cave void, the true qi of killing, the true qi of heavenly thunder, and the true qi of reincarnation are just scratching the surface."

"The real four true qi of the ancient times should be the true qi of time and space, the true qi of killing, the true qi of thunder and fire, and the true qi of reincarnation, among which the true qi of time and space, and the true qi of thunder and fire, must be led by the true qi of the cave void and the true qi of the heavenly thunder before it can be achieved."

Listening to the Flame Monarch in front of them, Li Yu and the others finally understood the reason, but there was one thing that made Li Yu's heart feel a shock, and that was his Seven Star True Qi.

If it was the Seven Stars True Qi, it would be fine, but since Li Yu used time and space in the Seven Tricks Ghost Tower to shuttle, Li Yu always felt that his Seven Star True Qi seemed to have a trace of connection with the Cave Void.

Now that he has heard that the two of the four great true qi of the ancients, the true qi of time and space and the true qi of thunder and fire, the time and space that he comprehended, shuttling, could it be the true qi of time and space, one of the four true qi of the ancients.

As soon as he thought of his seven-star true qi, it was very likely that it was the space-time true qi of the four true qi, Li Yu suddenly felt a heartbeat in his heart, the four true qi, if he was achieving the thunder fire true qi, then he would have the three major true qi in his body.

"So I want you to work with me to achieve Thunder Fire True Qi, although it is only the day after tomorrow, it is enough to compare to ordinary True Qi", the Flame Monarch said in a slightly expectant voice.

There was not the slightest hesitation at all, and Li Yu was also looking forward to it in his heart, because the Flame King had also said that if he achieved the Thunder Fire True Qi, it would be the Innate Thunder Fire True Qi, that is, the real Four Ancient True Qi.

Immediately, the Flame King told him everything he had to do, and the black-clothed young man in front of him, because it was related to his own interests, so the Flame King did not have the slightest sloppiness at all.

Subsequently, Li Yu and the Flame Monarch simultaneously activated the true qi in their bodies, and suddenly the Heavenly Thunder True Qi, the Heavenly Fire True Qi, and the two domineering true qi instantly entangled with each other and rose to the sky.

The two holy beasts behind him quickly retreated, even if they were holy beasts, but the true qi that belonged to Tianwei was not something they could compete with, not to mention that now it was actually Heavenly Thunder and Heavenly Fire.

"Such a powerful breath, it seems that this thunder fire true qi is indeed the four great true qi of the ancients, even I feel a palpitation", the heavenly armor looked at the one person and one beast in front of him, and there was a trace of envy in his voice.

The Dark Demon King nodded in the same way, but he didn't say a word, just stared at everything in front of him......

Heavenly Thunder True Qi, Heavenly Fire True Qi, just like two close brothers, slowly began to merge, and at this moment, Li Yu and the Flame Monarch were dripping with a drop of natal essence blood at the same time.

Whizzing

After the fusion, the thunder fire true qi was divided into two halves in the blink of an eye, and they shot into the body of a person and a beast respectively, and one person and one beast were all bodies for a while, and then stood quietly in place, not moving.

However, the aura around him became even more powerful, and at this moment, the true qi on the body of one man and one beast was no longer the pure black and fiery red that it used to be.

Li Yu's true qi turned red and black, while the true qi of the Flame Monarch was faintly red and black, and the gap between the acquired true qi and the innate true qi was unusually large.

Boom, a loud bang resounded throughout the Flame Mountain, and then in the sky above the Flame Mountain, thousands of miles of thunderclouds suddenly gathered, and the thunderclouds flashed with the power of pure black thunder and lightning.

"It's going to start, let's retreat, the thunder tribulation is not something we can resist", after saying that, the Dark Demon King and the Sky Piercing Armor quickly shot backwards again.

As soon as the two holy beasts left, the thunderclouds above the nine heavens suddenly slashed the power of thunder and lightning as thick as the thickness of the Dao arm, and directly slashed at the already unconscious Flame Monarch.

But what he didn't expect was that the power of thunder and lightning slashed at the Flame King's body, and the Flame King didn't even move, as if it wasn't him at all.

The power of thunder and lightning was still splitting the Flame King, and soon, the power of thunder and lightning that was splitting the Flame Monarch began to slowly melt into his body, but a trace of heavenly power in it was blocked outside.

The Flame Monarch achieved the acquired Thunder and Fire True Qi, so the innate power could not enter his body at all, but this was the case, the Flame Monarch at this moment had a painful look on his face.

A painful roar then rushed into the sky, and the roar seemed to anger the thunderclouds above the nine heavens, and then the power of thunder and lightning became more dense, like a downpour, crackling and splitting.

The Flame Monarch was still in a coma, and he didn't know what was going on, he just roared towards the sky, and the power of thunder and lightning that slashed at it, except for Tianwei, the rest of the heavenly thunder attributes were completely absorbed.
