In fact, when Niu Er set up a ban that day, he said that he would exchange the fairy grass spirit stone for freedom, who knew that this stingy rat demon, cursed and swore that he would not pull out a dime, and he hid behind people all day long and hesitated, whether to tell Niu Er about his hidden treasure.

On a sunny afternoon, there was a loud noise in the Mangniu Cave, black smoke rose everywhere, smoke was rising, and Niu Er, who was full of smoke and fire, ran out of the cave, gasping for fresh air, but there was Niu Yu's angry shout in his ears.

"Little rabbit cub, you loser's thing, that's a thousand-year-old spirit grass, and there are so many spirit stones, if you dare to refine the pill again, I will suppress you for a hundred years." ”

With a smile, Niu Er quickly slipped back into his hole, took out a cyan copper furnace and threw it on the ground, smashing a big pit in the hard ground.

This is exactly the alchemy furnace that Niu Er obtained in the hands of the god cultivator, and he has nothing to do recently, so Niu Er plans to make some preparations for the Spider Jindan to transform into a baby.

The avenue is difficult and dangerous, and it is difficult to step by step, especially the scattered cultivation monsters who do not inherit the exercises and only rely on the accumulation of spiritual energy, and the breakthrough of each realm is difficult.

For this purpose, the Terran monks specially invented a kind of Infant Transformation Pill, which can assist the breakthrough monk to successfully advance to the Yuan Infant Stage The chance of successfully advancing to the Yuan Infant Stage is increased by more than two percent.

Niu Er is not short of elixir, but he has no experience in alchemy, with the soul search of the Yuan Infant and some of the techniques mastered, he began to refine the pill by himself, more than ten furnaces in a row, none of them succeeded, and wasted a lot of spirit grass, which made Niu Yu furious.

Summing up the reasons for the failure, Niu Er felt that there were two, one was that his fire control technique was not mature and he couldn't do what he wanted, and the other was that he didn't have the heaven and earth spiritual fire in his hand, and every time he used the flame of true qi in alchemy, it not only consumed true qi, but also cost a lot of spirit stones, which was even more difficult to control, so the explosion occurred.

Niu Er learned in Yue Shan's divine thoughts that there are some flames between heaven and earth that can absorb spiritual energy to grow on their own, and if they can subdue a spiritual fire, it will have huge benefits for alchemy, not only saving true qi, but also increasing the chance of becoming a pill.

The reason why Yue Shan was able to become an alchemy master was that when he was young, he got a low-level spiritual fire by chance, but unfortunately he was scattered by a tree root of the old man Tiemu on the battlefield and turned into countless spiritual energy, so when Niu Er saw it, he could only use spirit stones to refine medicine.

Within a radius of tens of thousands of miles from Wushan, only the Fire Dragon Cave is the best at using fire, Niu Er's eyes are bright, and he commanded the spider, and then secretly went down the mountain with his sword and flew to the west.

Along the way, there are steep mountains everywhere, there are no flat places, all kinds of wild beasts are rampant, flowers and plants are flourishing, and giant trees are towering.

About 800 miles or so, there is a black mountain peak rising from the ground, hundreds of zhang high, covered with countless caves of all sizes, occasionally flickering with firelight, blazing hot.

"Who came to my Fire Dragon Cave realm and didn't report his name?"

The fiery red figure fell from the sky, startling Niu Eryi, it turned out to be a fire crow in the infancy stage, after the transformation, a big black face, the feathers of the whole body were red like fire, and it moved.

"Senior, Niu Er in Xiawu Mountain, came to see my brother Huo Wu, please let me know. "Niu Er didn't dare to be presumptuous, after all, it was not his own territory, and it was not worth it if he was beaten.

"It turned out to be the second young master of Niu, please forgive me for not seeing it clearly, but my son-in-law has been in retreat, I'm afraid I can't see you. The black-faced man didn't dare to slack off, after all, his identity was different.

"Ah, can Huo Muyun's predecessors be in the cave?" After the war, many people's cultivation has improved, and retreat cultivation is a common thing, and Niu Er can't be forced.

"Well, the king is also in retreat, and he can't see guests. The man replied honestly.

"Then who else is not in retreat?" Niu Er was speechless, his heart would not be so coincidental, there were countless things in the Fire Dragon Cave, and as a demon king, he also went to retreat. ...

"Well, the eldest lady of my family is here, but it's ....... "The black-faced fire crow seems to have something unspeakable, and he doesn't dare to speak.

"Oh, but what?" Niu Er remembered that there was also a terrifying Huo Wushuang, and he didn't expect that there would be that monster who didn't open his eyes to make trouble.

Dahan looked left and right with a pair of eyes for a long time, and saw that there was no one around, so he cautiously approached Niu Er's body and said in a low voice: "The second master is not an outsider, so I'll just say it bluntly, my eldest lady has not been in a good mood recently." ”

Revealing a 'you know' look, Niu Er suddenly realized, remembering that Huo Wuyi's face was full of scars, his whole body trembled, and a cold air came out of his heart, and he hurriedly said: "Thank you seniors for your advice, then I'll go back first and say goodbye." ”

"Is it Second Brother Niu ahead, since you have come to my Fire Dragon Cave, how can you not come in and sit down?"

The voice was as graceful as heaven, but Niu Er obviously saw that the black-faced man trembled, and a layer of fine sweat beads appeared on his head, and he hurriedly shouted: "Miss Qiqi, Wushan Niu Er Gongzi is here to visit." ”

Niu Er was startled by this person's sudden shout, a little overwhelmed, stunned in place, and saw a dazzling rainbow flying out of the fire dragon cave, fast as a meteor, drawing an arc in the air, and falling in front of Niu Er in the blink of an eye.

The fiery red Luo skirt, slender thighs, slender waist like willows gently rippling in the wind, a fan in the white jade fingers, Qiong's nose is tall, swan-like snow-white neck, and there is a charming style between the eye waves.

Before Niu Er could answer, he saw the black-faced fire crow bow forward and said in a deep voice, "Miss, Er Niu brought it." ”

"Hmm," Huo Wushuang's tall white jaw nodded slightly, "You can continue to patrol the mountain." Second Brother Niu can be entertained by me personally. ”

The black-faced man was obviously relieved, bowed his head in response, turned to leave, and didn't dare to stay for a moment.

"The second brother came to my Fire Dragon Cave, why didn't he inform my sister?

The eyes were scorching, as if there was resentment, the eyebrows of the jade were wrinkled, and the heart of Niu Er, who was watching, trembled, and hurriedly bowed his head and said: "Sister said and laughed, this radius of 100,000 miles, who doesn't know that my sister has the posture of sinking fish and falling geese, the appearance of a shy flower in the closed moon, and she deserves to be the first beauty of the demon clan." ”

"Oh, did your eldest brother say the same?" Ruhua's pretty face showed a brilliant face, her black hair moved with the wind, and there was a strange brilliance in her eyes, which shot straight into Niu Er's heart.

"Uh-huh, of course. My eldest brother is a real person, although he doesn't say it, but he must think so in his heart, and sometimes he wants to quickly become his own nest of nephews, hehe. Niu Er is very thick-skinned, boasting about his eldest brother, and he is not red at all.

Yanran smiled, charming and moving, and her beautiful face made Niu Er feel a little dazzling, and whispered: "Second brother is coming from afar, let's go to my cave to rest and have a cup of tea first." ”

The posture is graceful, the skirt is lightly swayed, and he walks slowly in the void, but it is as fast as the wind, and he takes a step dozens of feet away, and flies to the fire dragon cave in the blink of an eye.

Niu Erzu stepped on the flying sword, turned into a streamer, and tried his best to barely keep up, feeling that the gap in strength was too big, this was still someone who had not used his natal powers, otherwise he would have been thrown out without a trace.

For a whole day, Niu Er wasted countless saliva and put on more than a pound of spirit bee honey before he was lucky enough to escape Huo Wushuang's hospitality and return to Mangniu Cave.

"The second master is back, and the little one will greet you. ”

Before he could enter the hole, a fat golden mouse sprang out, with a flattering face, nodding and wagging his tail, greeting him.

Niu Er glanced at the rat demon suspiciously, when did the guy who sighed all day long sigh and cursed himself in a circle changed his sex? Could it be that there is a conspiracy?

But I didn't know that the rat demon had been entangled all day, and then heard about Niu Er's heroic deeds on the battlefield, and calculated in his heart that he definitely had a lot of wealth in his hands, and when he saw the tiger who was still babbling and toddler, he was even more stunned, and his eyes almost didn't fall out. ...

The transformation of the demon clan in the world is definitely a turning point in the demon life, and if you succeed early, it can mean that the potential is huge, and you can practice advanced Taoist techniques.

Later, the rat demon carefully curryed favor with Hu'er, paid the price of two spirit grass, and learned from his mouth that there was a transformation pill in the second hand of the cow, which surprised him even more.

All the way back to the cave, Spider was tidying up the cave, Niu Er sighed, and said to her: "Spider, you go and inform the whole mountain demon clan, this young master has offered a reward of 1,000 spirit stones, looking for the news of the spiritual fire of heaven and earth." ”

After staying in the Fire Dragon Cave for a day, Niu Er also learned some information about the spiritual fire. According to the characteristics of the types found by people today, the spiritual fire of heaven and earth is divided into four levels, heaven, earth, xuan, and yellow.

It is said that there is a heaven-level spiritual fire, which can be transformed into a human, cultivating the Dao, burning the river and boiling the sea, refining the heaven and earth, it is easy, and the strength is even comparable to that of a demon immortal, and few masters can surrender.

The Fire Dragon Cave is formed by the gushing of underground fire veins, although there are some earth fires, but they are scattered and domineering, there is no spirituality, and they can only provide the huge fire qi needed for cultivation, and the fairy grass elixir will turn into fly ashes when it enters, and it cannot be used for alchemy at all, even if it is to purify the ore, it is worth the loss.

At a loss, Niu Er could only offer a reward to find the spiritual fire, otherwise the road to alchemy and prosperity of his dream would not be carried out at all, and there would be nowhere to find the pills needed for cultivation in the future.

"Second master, second master, I know where there is a spiritual fire, I know. ”

The golden rat demon jumped up and down in front of Niu Er's eyes, a pair of small eyes full of excitement, and screamed.

"Huh? Do you know what?"

I didn't think that someone would know as soon as I asked, but the rat demon, who had always been depressed, suddenly became positive, which made Niu Er a little uncomfortable.

"I know, I know, there is a spiritual fire next to my cave, according to my grandfather, it has been there since ancient times, and it has been burning until now, and it has never been extinguished. ”

The golden rat demon's eyebrows fluttered and danced, which surprised Niu Er.

From ancient times to the present, there are hundreds of thousands of years, and a spiritual fire has burned for tens of thousands of years, which is definitely beyond the imagination of ordinary people, and it is not an ordinary low-level flame.
