I saw Ye Tianyun's thunder seal suddenly getting bigger, with powerful thunder power flashing on it, suppressing the thunder spirit liquid.
The two forces of thunder collided in the air.
Under the suppression of the thunder dragon soul, Ye Tianyun's thunder seal fell into a disadvantage.
Under the attack of the thunder dragon soul, Lei Yin actually flinched a little.
"The soul of this thunder dragon is so fierce? Dad, do you want to break the soul of this thunder dragon?"
Ye Chen looked at the struggling Thunder Dragon soul, and his expression changed slightly.
Although this thunder dragon soul is a broken soul, it is a dragon after all. Its natural arrogance penetrates deep into the soul and cannot be easily surrendered.
Not to mention being swallowed by a magic weapon.
"This thunder dragon's soul is much more precious than Song Yuande's thunder seal. It cannot be broken. If this soul is broken, its value will be greatly reduced."
Ye Tianyun shook his head and said in a deep voice: "First absorb the outer part that has been refined into Thunder Yuan Liquid."
As soon as he finished speaking, Ye Tianyun made a hand seal, and all the energy in his body poured into the thunder seal in the sky. Suddenly, the thunder light flashed, and a powerful suction force suddenly burst out from the thunder seal, swallowing it crazily.
With the power of this Thunder Yuan Liquid.
This thunder essence liquid is the product of Song Yuande's natal magic weapon being melted by the fire spirit. Basically, some junk materials have been removed, and the rest are the finest thunder attribute materials.
Even if Ye Tianyun's natal magic weapon does not swallow up these thunder essence liquids, just another weapon refiner can use these thunder essence liquids to refining a high-quality magic weapon.
"Town!"
Ye Chen gave a low drink, made a hand seal, and the power of chaos in his body burst out, forcibly suppressing the thunder essence liquid in the air.
Suddenly, the thunder essence fluid trembled violently, but it was still slowly swallowed by the thunder seal.
As these thunder essence liquids were swallowed up by the thunder seal, some strange runes slowly appeared on the surface of the thunder seal.
It's like a rune transformed from the power of thunder.
With the appearance of these runes, the aura of this thunder seal suddenly surged.
As the sound of thunder rang out, the aura on the thunder seal exploded, just like that, it jumped from the level of the best spiritual weapon to the mysterious weapon.
As the thunder seal broke through to the mysterious weapon, the aura around Ye Tianyun actually strengthened a little.
As the master of the Thunder Seal, under the influence of the enhanced Thunder Seal, the true energy in Ye Tianyun's body also surged.
"Finally arrived at the mysterious weapon."
Ye Chen's face showed a hint of joy.
It has reached the level of a mysterious weapon so quickly. It is obvious that the materials used in Song Yuande's magical weapon are very precious, otherwise Ye Tianyun's thunder seal would not have been able to achieve a breakthrough so quickly.
There is still more than half of the Thunder Essence Liquid left. Judging from this situation, there is indeed a chance for this Thunder Seal to become a quasi-celestial weapon level existence.
"Swallow!"
Ye Tianyun made secrets with both hands, controlling the thunder seal to wildly devour the thunder essence liquid.
As the thunder seal is promoted to a mysterious weapon, the suction force has been significantly enhanced.
Even the soul of the thunder dragon was somewhat unable to withstand the devouring of this thunder seal.
"Roar!"
Angry dragon roars rang out.
I saw that the soul of this thunder dragon suddenly erupted with a powerful aura, and an extremely profound power of thunder exploded, bombarding Ye Tianyun, Ye Chen and others.
"Are you going to risk your life? A ray of remnant soul actually has some intelligence, so you can be used as the weapon soul of this thunder seal."
Ye Tianyun was not surprised but happy, with a touch of excitement on his face.
"Broken!"
Ye Chen snorted softly, and the zhenqi surged around his body, directly shattering the power of thunder.
"Seal!"
Ye Tianyun gave a low drink, made a seal with both hands, and a sealing character suddenly flashed out, suppressing the thunder dragon's soul.
Suddenly, this letter was like a big net, directly sealing the soul of Thunder Dragon.
Click!
With a loud clicking sound, the thunder dragon struggled violently, and it even shattered Ye Tianyun's sealing technique.
"Seal!"
Seeing this, Ye Chen made a sealing tactic with both hands and also made a sealing tactic.
Two runes, one on the left and one on the right, completely sealed the Thunder Dragon.
"Dad, take advantage of this opportunity and devour the Thunder Dragon."
Ye Chen said in a deep voice.
"Okay!"
Ye Tianyun nodded, and with a thought, the thunder seal suddenly fell down, directly hitting the thunder dragon's soul.
The next moment, the thunder seal and the thunder dragon merged directly.
Violent thunder suddenly erupted from the thunder seal at this moment.
Ye Tianyun's expression changed, and he actually felt that the thunder seal wanted to escape from his control.
"Town!"
Ye Tianyun made seals with both hands and shot out seals one after another towards the thunder seal.
As these seals are integrated into the thunder seal, the thunder seal gradually stabilizes, and the aura is also growing rapidly.
"It's almost done."
When Ye Chen saw this, he breathed a sigh of relief.
The thunder seal slowly stabilized, and it was obvious that the soul of the thunder dragon had been suppressed.
After all, the soul of this thunder dragon is not very strong. Now as long as it is suppressed by force, it can be slowly refined.
With the help of the soul of this thunder dragon, this thunder seal will definitely be able to transcend the category of top-grade mysterious weapons and enter the realm of heavenly weapons.
Suddenly, streaks of thunder appeared above Ye Tianyun's head.
Countless thunders slowly emerged and roared angrily towards Ye Tianyun.
At this moment, not even the formations Ye Chen arranged around him could block the thunder that filled the sky.
At the same time, the aura of this thunder seal was improving rapidly, and it was quickly upgraded from a basic mysterious weapon to an intermediate mysterious weapon, and then reached a high-level mysterious weapon.
As the level of the thunder seal increases, more and more thunders appear above everyone's heads, as if they don't want the thunder seal to successfully break through.
Boom!
There were bursts of thunder from the thunder seal, and a thunder dragon was seen hovering around the thunder seal.
A mighty breath spread suddenly.
"Finally, we have reached the top-grade mysterious weapon."
A flash of light flashed in Ye Chen's eyes.
This is the first time that Ye Chen has seen a magic weapon progress so quickly.
In less than an hour, it went from a top-grade spiritual weapon to a top-grade mysterious weapon.
Boom!
As if feeling the breath of the thunder seal, these thunderbolts suddenly appeared above Ye Chen and others, roaring towards the thunder seal.
"What a huge thunder tribulation. Is this the thunder tribulation that occurs when a magical weapon is promoted? This is too powerful."
Ye Chen looked at the lightning disaster above his head and frowned slightly.
The intensity of this thunder catastrophe is not even weaker than the Yuan Hai catastrophe when Su Xiyue opened up the nine-foot Yuan Hai.
Ordinary top-grade mysterious weapons that break through to heavenly weapons should not attract such a powerful thunder disaster.
According to the posture of this thunder tribulation, it seems to be completely destroying the thunder seal.
"Is it because of the soul of the thunder dragon?"
Ye Chen frowned, looking at the thunder dragons surrounding the thunder seal, a hint of speculation emerged in his heart.
