You have to ask how hot is the Eight Hundred Miles Flame Mountain?

Look at the rocks beneath your feet, the hard stones, all burned to powder, forming a thick layer of lime powder, which is spread on the ground.

As soon as the foot fell, lime powder flew all over the sky, and Yu Duxiu's clothes, boots, and even hair were covered with lime powder.

The crane is clever, refuses to fall, just flies in the air, constantly circling back and forth, this crane is a fairy bird cultivated by the sect with a secret method, can carry people to fly, and has good combat effectiveness, ordinary demon beasts are not its opponents.

"It's a mistake, this eight-hundred-mile flame mountain is extremely vast, and I don't know how to control the clouds, how can I find silk in a short time, if I miss the apprenticeship time because of refining, it will be worth the loss" Yu Duxiu touched his chin, glanced at the limestone under his feet, and then looked at the continuous flame mountain around him with a pair of eyes, revealing a trace of thought: "This fire silkworm likes to survive in the flames the most, and the eight hundred miles of flame mountains can be suitable for the fire silkworms to survive, only in the magma."

Yu Duxiu stepped forward, lime powder flying, even if he was a martial arts master, he couldn't avoid the flying dirt at this time.

Walking and stopping in the Eight Hundred Miles of Flame Mountain, Yu Duxiu finally discovered the unusual thing about the Eight Hundred Miles of Flame Mountain, not all the mountain stones here have been turned into powder, there are still many mountain stones that are still intact, and the rocks that can be preserved under the burning of various flames such as heavenly fire and earth fire, their heat resistance, hardness, and non-secular things can be compared, even if it is an ordinary stone, if it can be tempered a thousand times, it should also be eliminated from the magazine and become the material of the immortal family.

Stomping his feet hard, Yu Duxiu shook his head, this mountain stone is not something that he can shake, what can't be burned by the fire that day, how can he destroy it by himself.

"Where is the fire silkworm" Yu Duxiu looked around, but the next moment, he suddenly felt that the fire bead in his arms emitted a scorching breath, burning his skin painfully.

"Huh?" The treasure moved, and Yu Duxiu suddenly became vigilant, looked around, and seriously felt the surrounding qi.

In the depths of the endless magma, a fire-red cocoon several meters long floats in the magma, and a wave comes from the darkness, the cocoon trembles slightly, stops on the fluctuating magma, seems to be sensing something, and the next moment I see that the cocoon is like a flying boat, bringing waves in the ocean of magma, following the induction in the dark, flying towards the top of the magma, the magma is surging, the cocoon breaks through the air, and jumps on the mountain rock.

stepped on the hard rock, but the next moment I saw a red streamer with a bang, crashing towards Yu Duxiu.

Yu Duxiu has been practicing martial arts since he was a child, coupled with the refining of the ancestral dragon's true blood, his physical body has been transcendent and reborn, far surpassing ordinary cultivators.

When the cocoon attacked, Yu Duxiu thought it was a volcanic eruption and shot out of the rocks.

The speed of the cocoon was so fast that Yu Duxiu took it for a fireball at first sight, and his body trembled to avoid the cocoon.

The fiery red cocoon stopped in the distance, stopping the shockwave, and then it spun again, rushing towards Yu Duxiu again.

This time, Yu Duxiu took advantage of the cocoon to adjust its direction and saw clearly what kind of fireball it was, but a bright red cocoon, constantly rolling in the void, like a flame.

"Fire silkworm" Yu Duxiu said subconsciously.

The cocoon kept colliding with Yu Duxiu in the void, and Yu Duxiu saw clearly, not that the fire silkworm could fly, but that the cocoon woven by the fire silkworm had an elastic force, and every time the cocoon landed, it would slightly adjust the direction, gravity, and then fly up with the elasticity of the cocoon.

"This beast is so cunning, he knows how to use elastic force to gallop back and forth, and collide with me, I'm afraid it's not shallow" Yu Duxiu casually untied the three-pointed two-edged knife behind his back, and then wiped his palm, and the strong bow was held in his hand, bending the bow and arrows, and the arrows instantly crossed the void and shot towards the bouncing cocoon.

The wooden arrows had already turned to ashes before they could get close to the cocoon.

"It's such a high temperature, and the special wooden arrows actually turned into fly ash in an instant, if the body comes into contact with it, I don't know what the consequences will be, but it is possible to be vaporized in an instant."

While thinking about it, Yu Duxiu put away the longbow, and after carefully dodging the blow again, he saw the three-pointed two-edged knife in Yu Duxiu's hand suddenly stabbed out.

"Zizi" The sound of the gold and iron exchange sounded, Yu Duxiu's three-pointed two-edged knife was worthy of being a magic weapon, the flame could not help him, and the big cocoon touched, but did not cut the big cocoon, but the sound of gold and iron intersection.

The next moment, the mana of Taiping Dao was poured into the three-pointed two-edged knife, but I saw a blood-colored silk thread flashing on the bright blade of the three-pointed two-edged knife, as if it was a winding earthworm, or a blood-colored spirit snake, a suction force came out of the three-pointed two-edged knife, and the next moment I saw a drop of blood like a flame flying out of the extremely strong cocoon, which was a burning flame.

The flame was instantly absorbed by the three-pointed two-edged knife, and the temperature of the three-pointed two-edged knife rose sharply in an instant, as if it was like a red-hot soldering iron, so hot that people couldn't hold it, and the water vapor in Yu Duxiu's hand gathered, was constantly evaporated, and then converged again.

There was a shrill chirp from within the cocoon, as if it was angry, as if it were roaring.

The cocoon was trembling, and the whole mountain was trembling slightly.

Yu Duxiu's face became more and more gloomy, the fire silkworm in this big cocoon was boundless, and he was here to capture the fire silkworm, not to deliver food.

This fire silkworm was hidden in the big cocoon, and it was already the first to be invincible, and Yu Duxiu couldn't think of any way to break through the opponent's defense at this time.

Facing an already invincible opponent, how should this battle be fought?

However, God seemed to be helping Yu Duxiu, but he saw that the trembling cocoon was instantly still, from high-speed movement to sudden stillness, which was a strict disobedience to the picture, breaking the law of movement.

"Click", although the sound is not loud, but it is like a thunderbolt in Yu Duxiu's ears, I saw a fist-sized hole appear at the top of the big cocoon, a strange flame came out, and the hard rock underground was ignited instantly, it was a rock that had experienced countless flame calcination, and it was actually ignited by the flame in the big cocoon, I don't know what kind of terrifying creature was bred in this big cocoon.

In Yu Duxiu's shocked gaze, he saw a "big snake" that was as thick as a thigh and a long and winding body squeezed out of the narrow hole.

The answer is yes, because he saw it with his own eyes.

This is not a snake, this is a fire silkworm, a fire silkworm that has lived long enough.

Taking advantage of the fact that the fire silkworm had not completely crawled out, Yu Duxiu made the first move, and the three-pointed two-edged knife in his hand shook and slashed towards the body of the fire silkworm.

There was a cold light in the eyes of the fire silkworm, and a pair of eyes seemed to have feelings, staring at Yu Duxiu deadly, and did not resist.

With a "bell", Yu Duxiu's three-pointed and two-edged knife slashed at the head of the fire silkworm, but he couldn't cut it anymore.

"So hard" Yu Duxiu suddenly withdrew the three-pointed two-edged knife, and the fire silkworm still moved his body unhurriedly: "Boy, Ancestor, I have thousands of years of Taoism, this body of skin and flesh has been scorched by countless flames, and it is three points harder than that iron stone, although the treasure in your hand is good, it seems to have been traumatized, and it is still sleeping, a sleeping magic weapon can help me."

"It's troublesome" Hearing that this fire silkworm actually spoke human words, Yu Duxiu's heart sank, and he could speak human words, coupled with the thousand-year-old Taoism, this old guy is simply invincible to Yu Duxiu, everyone is invulnerable, standing there and letting you kill you can't kill you, what can you do? .

"Ancestor, I have been sleeping for a thousand years, if I didn't feel the breath of the ancient fire-based magic weapon on you, I am afraid that I will sleep for ten thousand years, and then I will directly break out of the cocoon and turn into a supreme demon king and demon saint, although you disturbed the ancestor's sleep, but the fire-like treasure on your body is enough to make up for the loss of the ancestor" The fire silkworm looked at Yu Duxiu greedily with a pair of eyes.

"Fire-like Treasure" Yu Duxiu looked at his whole body, and suddenly remembered the fire bead.

It must have been the fire bead that attracted this fire silkworm ancestor, originally Yu Duxiu was still having a headache how to find the fire silkworm, but now it's good, this fire silkworm not only came directly to the door, but also came directly to a big guy.
