Xiao Yan's eyes swelled with a touch of heat. About to uncover the secret of why the jade box and the stone tablet were indestructible, Xiao Yan couldn't suppress his excitement and urged the demon bloodline, and wrapped three six-star demon cores at once with his fighting energy......

As the six-star demon cores that had absorbed the Emperor's Source Qi piled up around Xiao Yan's body, Xiao Yan's aura and fighting qi fluctuations were also quietly becoming stronger......

Finally, Xiao Yan's aura became turbulent, and the fluctuations of the fighting qi also began to stir, and soon, like a flood breaking through the floodgate, a majestic fighting qi gushed out from Xiao Yan's body, rushing all the demon cores around him towards the surrounding walls of the practice room.

Six-star peak, breakthrough!

Xiao Yan stood up excitedly, exhaled a breath of turbid breath in his chest, felt the fighting qi surging in his body, and couldn't wait to take out the mysterious jade box, just looking at it so eagerly, his hands couldn't help but tremble a little.

Taking a few deep breaths to calm his mind, Xiao Yan's heart moved, and the fighting qi of the six-star peak and the purple-red heavenly fire poured out of his palm at the same time to wrap the jade box. Urging the power of the Heavenly Fire, which fused with the four Heavenly Fires, to increase the output of Dou Qi, several tiny cracks began to spread on the surface of the jade box; Then urge the power of the heavenly fire, and then increase the output of the fighting spirit...... Gradually, under the continuous injection of the power of heavenly fire, in Xiao Yan's worried gaze, accompanied by a burst of 'click' cracking sounds, the cracks on the surface of the jade box became larger little by little, and the jade box began to shake with a small amplitude.

Looking into the jade box through the crack, there seemed to be a layer of airflow blocking the jade box, but Xiao Yan could only vaguely see that there was light circulating inside.

continued to inject the power of heavenly fire, and after about a stick of incense, the jade box full of cracks stopped shaking, and the sound of shattering no longer sounded.

'Open it for me!' Xiao Yan suppressed the excitement in his heart, and with a slight shock of his palm, the jade box shattered and opened, bursting out with two brilliant rays of light.

Xiao Yan narrowed his eyes slightly, staring at what he was holding in his hand, and the color of ecstasy in his eyes surged.

There were two flames floating in his palm!

A ball of dazzling red, through the flames, you can faintly see that there is an illusory phoenix inside! The phoenix spreads its wings at will, and the dazzling red light flies in the air.

The other light was extremely soft, like a faint moonlight, but it gave people an extremely cold feeling, which made Xiao Yan shudder.

Oh, my God! It turned out to be the 'Nirvana Rebirth Flame' ranked eleventh on the Heavenly Fire List and the eighth-ranked 'Guanghan Ice Flame'!

Xiao Yan almost exclaimed. Although he had never seen them, the characteristics of these two flames were too obvious, and Xiao Yan knew their names at a glance, and his heart was already happy.

Reluctantly looking at the two heavenly flames, Xiao Yan took out the 'indestructible' stone tablet.

'Inside the jade box are two top-ranked heavenly fires, what could be in this stone tablet that can't be broken? Xiao Yan thought happily, summoned the Heavenly Fire Ancient Ruler, and smashed it down against the stone tablet.

'When! ”

Sparks flew everywhere, and the stele did not move.

'It's not really going to be bad, is it?' The corners of Xiao Yan's mouth twitched wildly, and his eyes revealed ruthlessness, "Lao Tzu doesn't believe it, Lao Tzu can't smash you even if he is at the peak of the six-star rank!" ”

Xiao Yan was ruthless, picked up the Heavenly Fire Ancient Ruler and slashed it down fiercely. Ten feet, 100 feet, 1,000 feet...... Xiao Yan didn't know how many feet he had smashed, but the stele only lost a layer of stone skin.

'What kind of material, so hard?!' Xiao Yan wiped a handful of sweat and looked at the stone tablet in front of him, and the corners of his eyes twitched.

'Damn, I really don't believe it!' If it doesn't work in January, it's a year, and if it doesn't work in a year, it's ten years, I see how many layers of stone skin you have fallen! After a few breaths, Xiao Yan raised the Heavenly Fire Eternal Ruler again, and was about to smash it down.

But at this moment, the stone tablet that Ren Xiaoyan couldn't smash even if he smashed it violently suddenly shattered by itself!

With a burst of 'popping' sound of stone breaking, pieces of broken stones slowly floated away in Xiao Yan's stunned, and finally suspended in mid-air, each piece was separated by a certain distance, and each piece was connected by a hazy light, and gradually intertwined into a halo of light slowly rippling, and at the same time, a little faint brilliance gathered from all directions, all of which were not in the halo, as if the broken stones were accumulating some kind of mysterious energy.

'This ......' Xiao Yan looked at this scene in amazement, déjà vu, but not sure, he took a step forward and reached out his palm to grab a piece of gravel.

Just as Xiao Yan was about to grasp it, a low roar suddenly came out from the 'Gravel Formation', like a muffled thunder before a summer rainstorm.

Xiao Yan hurriedly withdrew his hand and watched the strange 'Gravel Formation' vigilantly.

The pieces of rubble began to slowly gather, and under Xiao Yan's gaze, they gathered into a human-shaped stone lump.

'Hahaha......' After looking at it quietly for a long time, Xiao Yan laughed wildly, "I can't think of it, I really can't think of it, no wonder this stone tablet is so hard that it is beyond imagination, it turns out that it is not a stone at all, but a spirit seal!" And it's also a spiritual seal without consciousness! ”

At this moment, Xiao Yan's heart seemed to have drifted from the earthly purgatory of magma to the flowery paradise on earth, and every cell was emitting a hearty cheer. (To be continued......)
