The little beast's dull eyes reflected the figure of the first seat of the Chengyang Palace, and it was motionless for a moment, and then it was placed aside by Luoyu along with a pile of sundries.

The corners of the Chengyang Palace's mouth twitched slightly, but before Luo Yu turned back, he regained his usual expressionless coldness.

Summoning a flame in his hand, the first seat of the Chengyang Hall said in a flat tone: "In ancient legends, there are strangers who are born to communicate with each other about a strange power between heaven and earth, calling for wind and rain, and are regarded as the darlings of heaven and earth. One of them was revered as the god of thunder by the ancient ancestors, and legend has it that he finally died with people on the top of Qiongmo Mountain, and then it turned into a thunder field, with dark clouds that did not disperse for thousands of years, and the thunder shone brightly, connecting the heavens and the earth. According to historical records, descendants have found a strange flame on the top of that mountain, which contains the power of thunder. ”

After a slight pause, he continued to say to Luoyu, who was staring intently at the flames in front of him, "This is where it came from. Of course, the mountain called Qiongmo no longer exists, so it is impossible to verify the authenticity of the legend. This spark has been preserved in the Qingning Sect for tens of thousands of years, and it is one of the oldest sparks here, but unfortunately no one has ever been able to fuse, you try it. ”

Swallowing his saliva, Luoyu thought to himself, what a big deal!

Rather than a flame, Luoyu felt that it was more like a gray whirlwind, and countless silver-white thunder and fire like lightning were entwined in it, constantly making a roaring sound. He carefully separated a little divine thought, and poked into it along a small opening in the seal.

Perhaps it was because few people tried to fuse with it, but as soon as Luoyu's divine thoughts penetrated into it, this thunder fire was like a hungry beast suddenly seeing delicious food, and its speed suddenly accelerated, and it suddenly pounced towards Luoyu's divine thoughts!

The eyes of the first seat of the Chengyang Hall lit up, and it really worked! This ancient fire has finally found a suitable owner!

He was happy for Luoyu in his heart, but he saw Luoyu shake his head and took his thoughts back. But the flame was reluctant to let Luo Yu leave, and was about to struggle to leave the seal with him.

The first seat of the Chengyang Hall gently pinched a magic trick to restore the seal to its original state so that the flames would not escape. But the thundercloud whirlwind flame seemed to be alive, as if it had lost its beloved thing, lingering for a long time in the place where the seal had just been opened, refusing to leave, as if looking forward to regaining Luoyu's divine thoughts.

He could see that Luo Yu should still want to try other fires before making a choice, not much nonsense at all, and attracted another flame, still opened the seal a little, and at the same time said: "This is the depths of the Oriental Ocean, under the Wanzhang Trench where a large number of Absolute Yin True Water is gathered, when the heavens and the earth are occasionally turbulent, and the pure Yang Heavenly Thunder and the Absolute Yin True Water are stirring and changing, the Xuanming Thunder Fire was bred by chance. ”

As soon as Luoyu's divine thoughts entered, this random fluttering blue and blue flame suddenly burst out with dazzling blue light, and the whole was condensed a lot, swaying and dancing, like a ribbon winding up with Luoyu's divine thoughts.

But Luoyu still only felt it slightly, and then withdrew. The ribbon-like firelight shook its head and tail in a hurry, and clusters of silver sparks burst out from time to time, as if hoping that such a vigorous dance could be exchanged for Luoyu's favor.

After a few rounds of testing, the first seat of the Chengyang Hall was completely numb, and almost all the flames related to thunder and lightning were very close to Luoyu, and the reactions were more enthusiastic than the other, as if they wanted to escape from the seal and elope with Gen Luoyu immediately.

He had never seen such a situation, and he really couldn't make a choice for Luoyu, so he could only let him choose one by himself.

Luoyu looked at the enthusiastic and beautiful fire in front of him, his eyes were glazed, and he didn't know which one to choose. Scratching his head in confusion, he easily looked away, curiously looking at the more fires around him that displayed the seals.

The first seat of the Chengyang Hall did not urge, and occasionally introduced him to some particularly interesting ones to satisfy his curiosity," ...... Different types of flames require different containers and sealing methods, but generally speaking, the stronger the flame, the stronger the seal. ”

Huh, Luoyu was suddenly attracted by a lattice on the stone wall, and there was also a transparent sealing container inside, which was flickering with dense runes.

According to what the first seat of the Chengyang Hall just said, this should be a relatively complicated seal, but there was nothing in the container, wasn't it a waste of effort? Could it be that none of the people in their Chengyang Hall found the flames and escaped?

Luoyu pointed to the stone lattice and said in confusion: "Lord Shouzao, why is that container empty?"

Seeing that Luo Yu noticed this grid, the first seat of the Chengyang Hall was silent for a while before re-speaking.

His voice was deep, and he said slowly: "It is not empty, but a strange source fire that is formless and colorless, collected on the battlefield in the void of heaven a hundred years ago. At that time, all the extraterritorial Heavenly Demons were either repelled or destroyed on the spot, and many other people from our realm also died there with the enemy in the end......"

Luoyu never expected that the question he asked casually would involve this matter, and his heart beat a few times!

Then he suddenly reacted, this may be a good opportunity to explore the old things, so he forcibly concealed the shock in his heart, deliberately widened his eyes, and asked curiously: "What is the Heavenly Void? What is the Extraterritorial Heavenly Demon?"

As soon as the gaze of the head of the Chengyang Hall touched Luoyu, he knew that his master probably hadn't mentioned these things to him yet, so he briefly introduced a few words, cleverly and quietly avoiding the people and things related to Yinyu Peak.

"There is a world outside of the world we live in. A hundred years ago, a group of invaders broke our boundary wall and led a large army to attack it, and the extraterritorial heavenly demons are the collective name for these invaders, and the heavenly gap is the largest gap in the boundary wall.

"After the decisive battle, both sides suffered heavy casualties, and all the corpses, magic weapon fragments, and various residual energies in the void of the sky were mixed together, forming a violent spiritual power storm, raging and roaring, and no one could approach that area at all. The monks of our realm were still worried that if this gap could not be closed, there would inevitably be endless troubles in the future. But perhaps it was the healing power of the world itself that gave birth to a never-before-seen fire out of thin air nearby.

"I don't know if the generation of this strange flame is related to the various energies that were scorched during the two world wars, but it gradually burned everything near the battlefield, transforming it into formless and substantial source energy, and the sky gradually repaired and healed itself, and then this flame also disappeared without a trace.

"Fortunately, this is a long process, and the Chengyang Hall specializes in collecting all kinds of flames, so it has collected some in advance and kept them, but for the time being, no one has been found to match it. You didn't consume much of your thoughts today, so if you wanted to, you might as well try. ”

Ever since he learned about Yin Yu Feng's past, Luo Yu unconsciously had a sense of responsibility in his heart that even he was not aware of. He just thought that since this strange flame had such a magical origin, and it was also related to the battle of the Heavenly Void a hundred years ago, then he would try it anyway.

Without waiting for Luo Yu to ask more questions, the head of the Chengyang Hall waved his hand to summon the transparent container.

Luo Yu took a closer look and noticed that the scene he saw through the container would twist and shake from time to time, and it was indeed like an invisible flame was tumbling and burning. After careful observation for a while, he nodded solemnly.

Seeing that Luoyu was ready, the first seat of the Chengyang Hall pinched a very complicated magic trick, tapped it lightly, and carefully released the seal through a gap.

Luo Yu still followed what he had just done, and took out a trace of divine thought and wrapped his breath and probed over.

In the blink of an eye, a sudden change occurred!
