Although, Ji Tianxing guessed the intention of the Gale Demon King.
But he could neither escape from the dark prison nor fight the Gale Demon King head-on.
In desperation, he could only fly forward with all his strength.
He wanted to rush to the edge of the dark cage and then find a way to defeat the barriers of the dark cage.
However, he flew rapidly for more than ten miles in the darkness, but failed to reach the edge of the dark cage and returned to the same place.
Now Ji Tianxing was really at his wits' end.
He could only use his kung fu to resist the erosion of the evil spirit, and tried his best to think of ways to escape.
"The dark cage has a radius of ten miles. No matter what sword skills I use, it is impossible to break the cage.
The sword technique is useless, so I can only try that magic weapon."
Ji Tianxing murmured silently in his heart, and immediately took out a square golden seal from the space ring.
This is not only the Territory Lord's Golden Seal of the Tianchen Territory Lord, but also a soul-level magic weapon refined by the Emperor himself, the Mountain and River Seal!
Ji Tianxing has never used it since he obtained the Mountain and River Seal.
This time, he wanted to test whether the power of the mountain and river seal could help him escape from the dark prison of the Gale Demon King.
He held the Mountain and River Seal in his left hand and waved his right hand with a solemn expression, using the secret method to control the power of the Mountain and River Seal.
When he shot out streaks of true energy brilliance with his right hand and submerged them into the mountain and river seal, the entire golden seal immediately burst out with dazzling golden light.
"Whoosh!"
The bright golden light spread out, forming a golden light shield with a radius of five meters, wrapping and protecting Ji Tianxing.
The golden light contains sacred and powerful power, which immediately dispels the darkness and blocks the erosion of the evil spirit.
Ji Tianxing felt that the pressure was suddenly reduced, and the infinite evil energy in the cage could no longer touch him.
At this time, the voice of the Gale Demon King rang out from a cloud of magic mist a hundred meters behind him.
"Huh? What kind of treasure is this?"
The Gale Demon King's tone was filled with surprise and a hint of fear.
A sneer appeared on Ji Tianxing's face, and he shouted in a cold tone: "Of course it's a treasure that will kill you!"
When he finished speaking, he made a mysterious seal with his right hand, injecting the majestic true energy into the mountain and river seal.
"Open it for me!"
Ji Tianxing suddenly shouted coldly and activated the mountain and river seals to release an overwhelming dazzling golden light.
The bright golden light condensed into a huge beam of light and blasted towards the darkness behind him.
"boom!"
The hundred-meter-long golden light beam, carrying the power of destroying the world, passed through the obstacles of layers of magic fog and hit the black light barrier on the edge of the cage.
Only a loud "bang" was heard, reverberating fiercely in the dark sky.
The barrier at the edge of the cage was blasted with several huge cracks on the spot, spreading in all directions.
The entire dark cage trembled violently, as if it was overwhelmed and would collapse at any time.
In the dark cage, the demonic energy and black clouds surged violently, and the Gale Demon King suddenly let out a panicked roar.
"How is this possible? You, a lowly reptile, can actually shake my secret magic cage?"
Ji Tianxing saw that the power of the mountain and river seal was really powerful, and his eyes suddenly filled with joy.
"Just now I used the Mountain and River Seal for the first time, and I only exerted 10% of its power, but it was able to shake the entire dark cage..."
He cast the spell again without hesitation, releasing even more majestic true energy and injecting it into the mountain and river seal.
Suddenly, the mountain and river seal released an even more dazzling golden light, condensing into a more terrifying golden light pillar.
"boom!"
The two-hundred-meter-long golden light beam instantly cut through the boundless darkness and hit the barrier of the dark cage again.
Amidst the deafening loud noise, a huge hole was blasted out of the black light barrier on the spot, and dense gaps were opened.
The golden light beam passed through the hole and disappeared in the blink of an eye.
But the cracks around the hole are rapidly extending and expanding, making the entire dark cage crumbling.
Seeing that the dark cage was about to break, the Gale Demon King could no longer remain calm and roared angrily.
"Asshole! You little beast, you can never escape from this king's suppression!"
More than a dozen demonic clouds hidden in the darkness immediately gathered together and condensed into a giant humanoid beast hundreds of meters tall.
It was a giant beast covered in pitch black and covered with scales.
Its limbs are extremely thick and strong, its head is huge, its mouth is wide and flat, and its spine has several rows of sharp barbs on its back.
Moreover, it also has a huge crocodile-like tail covered with black barbs.
This ferocious humanoid beast is the true form of the Gale Demon King!
It roared angrily, pounced on Ji Tianxing as fast as lightning, and slapped Ji Tianxing hard with a pair of giant claws.
Its claws are as big as a two-story building, and the black claws are sharp and sharp enough to crush a thousand-foot mountain.
If Ji Tianxing is hit by the giant claw, he will be seriously injured even if he is not dead.
But Ji Tianxing did not flinch, looking at the Gale Demon King charging towards him with cold eyes, and once again activated the power of the Mountain and River Seal.
"Mountains and Rivers Dragon Shadow!"
The mountain and river seal once again released dazzling golden light, condensing into a golden spear shadow three hundred meters long, exploding with the power of destroying everything, and blasted towards the Gale Demon King.
The Gale Demon King felt the terrifying power of the golden gun shadow, and his body immediately shook, and his eyes widened in horror.
It subconsciously stopped killing, trying to avoid the bombardment of the golden gun shadow.
However, the distance between it and Ji Tianxing was too close, the speed of the golden gun shadow was too fast, and everything was already too late.
"Boom!"
A loud sound like thunder exploded, reverberating violently in the dark prison.
The terrifyingly powerful golden gun shadow instantly penetrated the Gale Demon King's huge claws and hit its thick, strong, scaly left shoulder.
Suddenly, the Gale Demon King was sent flying backwards and hit hard against the wall of the dark cage.
"Bang!"
With a dull loud noise, the black light barrier was shattered and completely collapsed.
The golden gun shadow passed through the left shoulder of the Gale Demon King, flew out of the dark cage, and disappeared into the sky.
The dark cage finally fell apart and turned into overwhelming demonic energy, spreading in all directions.
The Gale Demon King also screamed in pain, and black blood spattered from the wound. He fell from the sky and hit the dense jungle hard.
"Whoosh!"
Ji Tianxing's figure flashed through the surging demonic energy and flew back to the sky above the jungle.
He looked down at the jungle below and saw the Gale Demon King lying miserably in the jungle, still struggling fiercely.
"The soul-level magic weapon is really powerful! It's my first time to use it, and I can release such a terrifying attack before I have mastered the corresponding secret method.
Not only did he defeat the Dark Cage, he also severely injured the Gale Demon King at the seventh level of Tianyuan Realm!
If I can master the secret method of manipulating the mountain and river seals, I will definitely be able to make the mountain and river seals exert their power to destroy the world!"
