"It is said that after the demon clan cultivates to the realm of the demon king, even if he does not deliberately cultivate, his physical body is comparable to a medium-grade magic weapon, and it is indeed true, as for the red flame turtle, the defense power is almost close to the high-grade magic weapon. Duan Chen couldn't help but exclaim.

The three-headed primordial infant-level rat demon king besieged the Red Flame Turtle, and those attacks fell on the shell of the Red Flame Turtle, leaving at most some marks.

As for the head and limbs and tail of the Red Flame Turtle, the defense is also not weak, and it can also be retracted into the turtle shell at a critical moment, so it is even less likely to be injured.

"Okay, stop looking, it's time to act. Just as Duan Chen was staring intently at the battle in the field, the Seven Demon Lords suddenly reminded.

Duan Chen came back to his senses when he heard this, and he couldn't help but get nervous with his mood.

After all, it takes a lot of courage to fish in troubled waters under the noses of the four-headed primordial infant level demon kings and fierce beasts.

However, when he came to the depths of the Fierce Beast Forest this time, he was originally aiming for the Golden Crow Stone Mine in the Red Flame Turtle's lair, so he naturally couldn't retreat at this time.

At that moment, Duan Chen almost didn't hesitate to apply several concealment spells on his body, and then with the concealment effect attached to the Demon God Mask, his figure disappeared out of thin air all of a sudden.

After being invisible, Duan Chen cautiously flew towards the mountain peak in the distance.

This peak, Duan Chen had been secretly observing for a month and a half, and he knew everything about it, and when he secretly sneaked into the halfway point of the mountain, he immediately saw the secret cave entrance mentioned by Huang Fuyu in the jade slip information.

This cave is located at the foot of the mountain behind the peak, connecting to the nest of the Red Flame Turtle, and at the foot of the front mountain, there is another exit, which is the location where the Red Flame Turtle appeared before.

It can be seen that the secret cave entrance located in the back mountain is only a few feet in size, and it is obviously impossible for the Red Flame Turtle to enter and exit, but it does not know how to form it.

However, Duan Chen didn't have time to care about so much at this time, and after his eyes flashed slightly, he cautiously walked in, and released his divine sense to explore the surroundings.

I saw that the cave was very dry, and as I walked inside, the air became more and more hot.

After a stick of incense, Duan Chen appeared around a corner and stopped, and then glanced forward with his divine sense.

After a moment, with a look of surprise on his face, he walked quickly around the corner and walked forward, and his eyes suddenly brightened.

What appeared in front of Duan Chen at this time was a huge natural cave, with an area of more than 1,000 zhang and a height of more than 100 zhang.

On the top of the cave and on the stone walls, a golden-red ore grows, exuding a fiery aura.

Seeing these golden-red ores, Duan Chen's eyes couldn't help but light up, and there was a faint hint of excitement in his eyes.

These golden-red ores were the best fire attribute material he had been looking for, the Golden Crowstone.

It can be seen that a large part of the Golden Crow Stone Mine in this cave has tooth marks left on it, which is obviously left by the Red Flame Turtle.

Only fierce beasts that have reached the level of the Yuan Infant such as the Red Flame Turtle will eat the best fire attribute material like the Golden Crow Stone as food.

"There should have been a lot of golden black stones in this cave, but most of them were eaten by the Red Flame Turtle, and only this small part remained. ”

Duan Chen looked around the entire cave, licked his lips, and without hesitation, after his figure flashed, his person appeared in front of a golden crow stone mine, took out his tools and began to mine.

After mining dozens of golden black stones in a row, he stopped with a look of unfinished business.

"It's almost time to go. Although there were still many golden crow stone mines in the cave that had not been mined, Duan Chen did not dare to stay any longer, and immediately returned along the same path and returned to the back mountain.

At this time, in the battlefield not far from the mountain peak, the battle between the three-headed rat demon king and the red flame turtle was also carried out at a critical point.

At this time, the Diamond Rat King, the Lightning Rat King, and the Flame Rat King each displayed their own racial talents, and under the greatly increased strength, they were completely suppressing the Red Flame Turtle and fighting again.

Especially the Lightning Rat King, whose strength is faintly the strongest among the three demon kings.

I saw that after he displayed his natural powers, the small handful of purple lightning mark-shaped hairs in the center of his eyebrows continued to burst out of purple thunder and lightning, each of which made the Red Flame Turtle tremble, and his mouth continued to let out a painful roar.

Seeing this situation, Duan Chen, who had already come out of the cave in the back mountain, couldn't help but feel very happy in his heart.

It seems that this battle will soon be decided, if he continues to stay in the cave to mine the Golden Crow Stone Mine, he may be caught by the three major demon kings such as the Diamond Rat King after the battle.

Thinking of this, Duan Chen immediately didn't dare to stay any longer to mobilize the mana of his whole body,

Urging the phantom winged spirit boots under his feet to turn into a flash of magic light and break through the air.

"Huh?" Just as Duan Chen controlled the magic light and quietly left from the back mountain, the lightning rat king seemed to sense something, and his eyes looked in the direction of the back mountain as cold as lightning, as if he had discovered Duan Chen.

However, now that the battle has reached the most critical moment, victory is in sight, and it is impossible for the Lightning Rat King to give up dealing with the Red Flame Xuan Turtle and go after Duan Chen.

After all, a Red Flame Xuan Turtle at the level of the Yuan Infant Demon King was a treasure, and its value was not at all under that small Golden Crow Stone Mine, so it was naturally impossible for the Lightning Rat King to give up the big fish in front of him in order to hunt down Duan Chen, a Jindan monk of unknown origin.

On the other side, Duan Chen flew out for hundreds of miles in one breath with the help of the astonishing speed of the explosion of the Phantom Wing Spirit Boots, a medium-grade magic weapon, and saw that no one was chasing after him, so he slowed down with a sigh of relief and flew towards the outside of the fierce beast forest.

A few days later, he left the Fierce Beast Forest safely, returned to Anyang City, and directly teleported back to the Phantom Moon Demon City through the teleportation array in Anyang City.

Duan Chen, who returned to the Phantom Moon Demon City, did not stay long, and immediately returned directly to the cave mansion of the Fox Immortal Residence.

"Master, you're finally back. "The ghost who had been staying in the cave to cultivate the Blood God Gu was overjoyed when he saw Duan Chen come back, and immediately overjoyed: "During this time, I followed your instructions to give those Black Silkworm Demon Gu blood poison at regular times every day, most of the Black Silkworm Demon Gu couldn't last three days, and only about five hundred survived. ”

"Of the nearly ten thousand Black Silkworm Demon Gus, only more than five hundred survived?" Duan Chen was shocked when he heard this.

Although he had long known that refining Blood God Gu was not easy, after nearly 10,000 Black Silkworm Demon Gu had undergone initial cultivation, only more than 500 had survived, and this mortality rate still made him feel shocked.

You must know that this is only a preliminary cultivation, and after that, these surviving Black Silkworm Demon Gu will have to go through several cultivations before they can transform into Blood God Gu, and in this process, the number of Black Silkworm Demon Gu that can survive is even less.

However, as long as he could successfully cultivate several Blood God Gu that could breed offspring, it would be considered a success for Duan Chen.

"Let's go to the worm room. Thinking of this, Duan Chen immediately set off and walked towards the insect room.
