For three consecutive days, Niu Er practiced fire control in retreat, and manipulated the spiritual fire to refine the low-level Zhuji Dan, which could allow people to improve their qualifications, open up the muscles and veins of the whole body, and cast the Yuan Qi Dao Foundation.

With the spiritual fire, it is really different, Niu Er's divine thoughts are like silk, integrated into the flames, and the flame intensity can be easily adjusted in each place, so that the pills in the copper furnace are evenly heated, and the essence of each spiritual grass is refined, and there will be no scorching phenomenon.

It's just that this fire is different from others, it doesn't seem to consume true qi, but every time it is used, the qi and blood are weakened imperceptibly, but with its own powerful qi and blood, it can be restored in the blink of an eye, and it doesn't hurt.

In half a month, the technique is gradually proficient, and each furnace can produce Dan, and the rate of Dan is getting higher and higher. According to what he understood, the human Dan master was very strict, taking the number of Cheng Dan as the standard, from one, two to seven or eight now, and every time the technology was improved, the treatment changed dramatically.

Among them, nine is the extreme, and all those who produce nine pills in each furnace are the top grandmasters among the Dan masters, with a high status, and they are more noble than the sect masters of ordinary sects.

In the Mangniu Cave, because he didn't have to worry about the elixir, Niu Er started his career as a Dan Master, although the Dan rate was not high, the Dan Master couldn't stand the abundance of elixir, and he made fire and alchemy day and night, the blood coagulation pill that the demon beast needed after the spirit was enlightened, the bone quenching pill taken during the Qi training period, the Peiyuan Dan that the Jindan realm could increase cultivation, and the infant pill that could help the demon beast get married.

In the cave on the other side, Niu Yu was very angry, jumping like thunder, with a big black face with an iron face, and white smoke spewing out of his nose, which frightened the little demon on the side and didn't dare to breathe.

"You go, call the second young master to me. ”

"Yes. With the next sound, the little demon was like being pardoned, and trotted all the way out of the cave.

There is not much time, Niu Er, who has a comfortable face, walks in with his head in a leisurely manner, the alchemy has been very smooth recently, and the Infant Pill has been refined into eighteen, first give two to Spider Er and let her go to retreat and cultivate, and the rest has to be carefully calculated, where to use it appropriately.

Unexpectedly, as soon as he entered the cave, he was faced with a saliva waterfall, Niu Yu's eyes were spitting fire, his expression was hideous, his eyes were bigger than copper bells, and the water in his mouth was gushing.

"Xiao Er, you are obsessed with pills and waste a lot of elixirs, and the second uncle can still be ignorant when you are young, but you actually took three Yuan Ying in the treasury and took them to refine the medicine, do you know that they are the most important treasures in my Wushan, you ......"

After talking for a long time, seeing Niu Er's frightened expression, his face was moist and flowing down the corners of his face, so he turned his head in embarrassment, sat down indignantly, and his anger turned into a long sigh.

"Second son, it's not that the second uncle is distressed, it's really that those few yuan babies are very important, if they are given to their subordinates, they can make me Wushan have three more yuan baby demons, and their strength can surpass ordinary demon kings. Moreover, if it is difficult for you to get married in the future, you can eat one and you will be fine, but you ...... Hey. ”

Niu Yu was very hurt, although he wanted to educate him well, but he couldn't be ruthless and harshly scolded this pampered nephew, so he could only swallow his anger and turn into bitterness.

Depressed wiped away his saliva, Niu Er didn't dare to attack any grievances in his heart, and came to Niu Yu's side with a hippie smile, and said: "Uncle, don't be angry, it's also useful for nephews to take away Yuanying." ”

"Can I have three more Yuanying monks in Wushan?Can you get married in the future?Can you ......" Seeing Niu Yu's face turned blue, I was afraid that he was really angry, Niu Er quickly took out a jade bottle from his arms and handed it to his eyes.

"Hmm, what is this?" Niu Yu pulled out the cork and sniffed it, a rich aura erupted, and the true qi in his body was about to move, circulating in his body on his own, and he couldn't help but be surprised: "This is an elixir? What kind of Dan is this?"

"Infant Pill. Niu Er raised his head with his chest straight, put on a pose that he thought was cool, and said, "The best pill to help people get married." ”

"What?Infant Pill?" Niu Yu's eyes lit up, looking at the dozen milky white pills the size of a dragon's eye in the bottle, which were full of color, the glow was surging and flowing, and his heart almost jumped out.

It's not that I haven't heard of it, but the name of the Infant Pill is like thunder, and the other other pills in the demon clan can be unknown, but the Infant Pill and the Transformation Pill are the two most widely known pills, but they have always been in the hands of the human race, and it is difficult to see its shape when the monster only hears its name.

slapped Niu Er's head hard, almost slapped the cool calf down, and said with a smile: "Sure enough, it's my good nephew, good, good." It's the second uncle who blames you. With this elixir, why worry that my Wushan can't be vigorous, hahaha......"

Next, the two reckless cows got together and muttered for a long time, and then Niu Er left easily.

Three days later, above the beautiful Wushan Mountain, the aura was surging, and the colorful glow was steaming, converging into a huge whirlpool, surging to the top of the mountain, alarming the little demons within a radius of hundreds of miles to come to watch and discuss.

There are older seniors and old demons, reminding that this is a demon clan master who is impacting the Yuanying realm, and now I am afraid that he has successfully married a baby, and is absorbing the aura of heaven and earth to consolidate his cultivation.

In the next eight days, four people in a row on Wushan successfully got married, and the huge momentum made the demon kings of the surrounding mountains speculate about what treasures they had obtained on Wushan.

In fact, Niu Yu gave a total of five pills, but one person entered the peak realm of Jindan for too short a time, and he failed to marry a baby.

Two days later, Wushan released a message, so that the demon king in a radius of thousands of miles could not sit still, Wushan even got five infant pills, welcome all loose cultivation demon clans to join, or exchange spiritual objects for pills.

In the Mangniu Cave, Niu Yu and Niu Er's two uncles and nephews sat on stone chairs, drinking tea made from spiritual honey, chatting a few words, quietly waiting for someone to come to worship the mountain, and the spider stood behind him, constantly pouring tea for the two.

Unexpectedly, the first one to come was the beautiful and noble and graceful Huo Wushuang, who came in and shouted Niu Yu's heart so much that he almost gave her all the pills.

Fortunately, Niu Er was conscious and argued, crying that he had trekked through mountains and rivers, risked his life, and after a hard life-and-death struggle, he snatched this bottle of elixir from the hands of a Terran alchemist, and finally said that his saliva was dry, so that Huo Wushuang took out a Terran Yuanying in exchange for two pills.

The second one came to the green toad of Jubi Mountain, in the last war, he suffered the most losses, nine Yuanying masters were killed and six injured, all of the survivors were in retreat to heal, and now the red copper mine has to be supervised by himself, and no one can use it.

After some bargaining with Niu Yu, Green Toad used a hundred thousand-year-old spirit grasses and two Terran primordial babies in exchange for two pills, held them tightly in his hands, and left in a hurry.

Next, there were fewer and fewer pills, but the price was getting longer and higher, making the surrounding demon kings almost fight.

However, Niu Er had already disappeared with the spider and the rat demon, and he also took a little guy who couldn't speak.

Time is in a hurry, five years have passed, and Wushan is full of vitality, mining medicine on weekdays, striving for meritorious service to be rewarded by the king, being able to get a pill for cultivation, or being able to transform into a person, and most importantly, you can get a cultivation exercise.

There are also little demons in the mountain glade, holding various weapons, picking up their arms and smashing at each other, and individual cultivators will also make the spirit weapon hover and fly overhead, bringing up pieces of wind, colliding with the opponent's weapon, and sparks bursting.

It's just that in a group of savage demon beasts, a fifteen or sixteen-year-old boy, sweating profusely, his face was flushed, and he couldn't lift his arms, but he still refused to admit defeat, his dark eyes were full of perseverance, and he looked at a transformed demon opposite.

The long wind howled, and a black iron rod came to him, and the green tendons in the young man's hand burst out, and his body rotated, driving the long knife in his hand into the air.

With a sonorous sound, the long knife flew into the air with a soft groan, cut through an arc, and fell between the mountains and rocks.

"Okay, today Xiaoshi insisted on two more moves, and the progress is very fast, haha. "I am deeply relieved to have an old demon on the side.

"Thank you for your advice. After the young man thanked him, he turned around and left, returning to the cave to cultivate.

At the entrance of the Mangniu Cave, two figures stood on the edge of the mountain rock, watching the young man leave from a distance, and one of them said: "This kid is also a stubborn temper, similar to you." Two years ago, he came to the bottom of the mountain alone, and he was already dying, and if I hadn't found the ginseng in his hand with the tooth marks you left, I would have thrown him out long ago. Now that you're back, would you consider taking him as an apprentice?"

"Hehe, I didn't expect the second uncle's eyes to be so good, I also saw that the ancestors and grandchildren were pitiful, so I gave them the half-bitten elixir, but I didn't expect this kid to be bold, and he dared to take it as a token and went to my demon clan territory to learn from the teacher. ”

These two people are Niu Yu and Niu Er's uncle and nephew.

Niu Er, who had left the Mangniu Cave for five years, returned from retreat, and his cultivation actually reached the early stage of the Yuanying, and the one-foot-sized Mangniu Yuanying in the dantian made Niu Yu so excited that he almost drank all the wine in the cave.

The two talked all night, only to learn that Niu Er had actually found a spiritual mine, using the strong aura there, the cultivation speed was fast, and with the assistance of the elixir, it took eight years to consolidate the cultivation of the golden pill and break through the Yuanying realm in one fell swoop.

At this time, I came back to prepare for the tribute once every sixty years, and all the many demon kings under the leadership of the Peng Demon General were all on the day of the tribute, all of them arrived, not only to offer tribute, but also to listen to the demon general's preaching, and to discuss with other demon kings, and exchange the items they needed each other.

It's a long time, and although it's not a long way to go, it's a year to prepare in advance.

It's just that he didn't expect that as soon as he returned to the mountain, he heard that a human boy made a special trip to Wushan to find Niu Er to learn art, which made him feel strange, so he took a look at it from afar.

The young man's name is Shi Xiaosong, born in a small village called Shuangmiao in the north of Wushan, his parents died early, with his elderly grandfather to collect medicine in the mountains for a living, seven years ago he encountered a tiger on the road, and the critical moment was that Niu Er, who had not yet transformed at that time, saved the two grandparents and grandchildren, and also sent half of the old ginseng.
