If you don't believe it, just try it out of the cave yourself, what's the danger outside?" Murong Xiu said.

"No, since I promised the Emperor of Heaven, then I must keep my promise, unless there is a call from the Dragon Sword, otherwise, I would rather stay in this cave for the rest of my life, boy, don't grind and chirp, hurry up! Anyway, you don't want to trick me into letting you out," the blood dragon was a little impatient.

"Okay! Since you don't know what to do, then look at the sword!" Murong Xiu said, his figure suddenly burst up, stirring the wind and thunder, stirring up the spiritual power, and a sword slashed out, as if there were thousands of sword shadows, and the sword qi that rushed to the sky cut out cracks on the stone wall, and slashed at all parts of the blood dragon's body.

"That's right, let me see how strong your combat power is now?" The blood dragon roared in a low voice, and the red spiritual power light on the dragon's body rolled up, forming an indestructible spiritual power qi wall, slamming into the thousands of indestructible sky-piercing sword qi that Murong Xiu slashed from, and with the loud roar, Murong Xiu's "Thousand Autumn Thousand Sword Slashes" It actually shattered the blood dragon's solid aura defense, but the power on the sword blade was greatly reduced, and it was not enough to hurt the blood dragon at all, and at the same time, the strong horizontal force that shook back from the blood-colored qi wall also retreated Murong Xiuzhen to a few zhang away.

"Boy, is that what you can do? Look at my counterattack," the blood dragon snorted coldly, his huge body twisted and turned, and the world-destroying spiritual power rushed out, he had been in this cave for thousands of years, so he couldn't be more familiar with the terrain in this area, although his body was huge, it was quite fast and flexible when it moved, and on his dragon body, he would constantly swallow and release a blood-red spiritual power shield to make up for its huge size, which was easy to be hit by the other party.

"Blood Dragon Thunderbolt Gall!" "From the blood dragon's bloody mouth, a small yellow ball the size of an egg suddenly spit out, and the small ball shook in the wind, and it quickly became larger, and the surrounding blood-red spiritual power was entangled, and with a "Teng" sound, a cluster of spiritual flame light circulated around the ever-growing thunderbolt blood gentian, and at the same time, a faint thunderbolt thunder sounded inside the blood gentian.

"Explosion!" The blood dragon roared, and the gentian suddenly burst open, and countless thunderbolts mixed with electric light and flint, like sparks in the sky, slashed towards Murong Xiu, this thunderbolt and lightning in the sky, although it was not as powerful as the "Ten Thousand Thunder Tribulation", but it was not much different, but Murong Xiu was not afraid of the power of thunder, on the contrary, in the face of the violent thunderstorm, she showed a trace of contemptuous smile.

"Hmph! Playing thunder with me, it's just looking for death!'Thunder Spirit Sword Technique!" Murong Xiu pointed his sword obliquely into the air, mobilizing the fierce thunder power of his whole body, those thunder and lightning spiritual power, with the rapid improvement and breakthrough of her realm, has already become more powerful, strong and violent, once it runs, the golden thunder and lightning power will flow all over the body, and there is an arc spark "crackling" outside the body like a substance The sound reflected her surging green veins and blood, and her tall body like a giant in the wilderness, as if she was a thunderous god of war.

The blood dragon never imagined that when such a majestic thunder power of his own slashed near Murong Xiu's golden sword light pillar, it was actually devoured into that sword in a steady stream, and thousands of thunderbolts gathered together, how powerful it was!

The long sword trembled violently and buzzed, even Murong Xiu herself was a little unable to hold it, but she still gritted her teeth and persevered, letting the violent thunder and lightning wash the blades of the giant sword to the fullest, until they merged into a huge river of thunder and lightning, completely pouring into the golden glittering sword body.

"What? you actually devoured my Blood Dragon Thunderbolt Gall, give it back to me!" The Blood Dragon was shocked and annoyed, that Blood Dragon Thunderbolt Gall was almost its strongest killer weapon, and it actually let this kid devour it in a single moment, how could this be? In a rage, its entire blood-colored dragon body also turned into a huge blood-red dragon-shaped giant blade, smashing the endless void, wrapped in monstrous murderous aura, and slashed towards Murong Xiu.

"Haha! The Blood Dragon Thunderbolt Guts are nothing more than that! Do you know what I devoured your thunder power for? Just to give it back to you!" Murong Xiu laughed and threw the sword in her hand into the air, the power of thunder and lightning that she could absorb was limited after all.

Moreover, she also relied on the power of condensing the thunder and lightning of the outside world to induce the "Ten Thousand Thunder Tribulation", not her own thunder power, so the ferocious thunder power blasted by the blood dragon thunderbolt gall, Murong Xiu only stored most of them in the sword, plus the thunder power she possessed, that kind of power was enough to destroy everything.

The two giant blades, each wrapped in an invincible power, the dragon-shaped giant blade is the blade of the origin of the blood dragon, which has its own earth-shattering power, and the Moon Shadow Sword is poured with all the power of Murong Xiu's thunder and lightning, as well as all the thunder power of the thunderbolt gall, and the two spiritual powers superimposed together flow wildly, making the Moon Shadow Sword spit out countless winding and twisted arc golden rays, like a spirit snake dancing wildly, the sound of "boom" is deafening, even Murong Xiu can hardly estimate how powerful the Moon Shadow Sword that appeared is?

The two domineering giant blades finally collided fiercely together, and the Moon Shadow Sword released all the power of thunder, "booming" and destroying the majestic power of the world, directly crashing the dragon-shaped giant blade out, flying messily, "booming" hit the stone wall, the giant blade also became fragmented, incomplete, the power of the thunder, the remaining momentum, slashed on the stone wall, it was actually the stone wall split a one-foot-wide crack, the crack directly led to the outside of the mountain, and the light in the cave was suddenly much brighter.

"What a strong force!" Murong Xiu exclaimed, Yue Chan also nodded with satisfaction, this kind of power is probably not worse than the Ten Thousand Thunder Tribulation, but the Ten Thousand Thunder Tribulation can generate a thunder array, so that the opponent has nowhere to hide, and this thunder blow, in terms of the power of a single critical hit, has exceeded the Ten Thousand Thunder Tribulation.

At this time, the blood dragon, after receiving such a heavy blow, was immediately blown out of its original form, but it had become a blur of flesh and blood, its body was incomplete, and its big mouth kept spitting blood foam, and it was extremely embarrassed to pant with "hum", but it was still suspended in the air, even if it was defeated, it could not lose the dignity of the true dragon.

Murong Xiu wanted to fly out of the cave immediately, but this blood dragon was the key artifact to find the Tenglong Sword, so how could he leave it alone?

"Okay! You've won, you can go!"
