Lu Chen was startled, and sacrificed the Bagua True Fire Furnace in his body, the moment it appeared, the entire cave suddenly let out a violent roar, only to see that the Jiuding Dan Furnace began to shake continuously, and countless colorful lights shot out, all converging towards the Bagua True Fire Furnace.

"It's really a real furnace of gossip. ”

Jiang Yi screamed in surprise, his face full of incredulity.

"As soon as the gossip furnace came out, everyone worshipped. Danzu smiled and said, "Put it away quickly, otherwise my pot of pills will have to be discarded." ”

Lu Chen was stunned for a moment and said, "Master, why did I also sacrifice the Bagua True Furnace when I was in the Holy Burning Square just now, but it didn't cause any changes in Dongfang Yu's Black Dragon Pill Furnace?"

"Didn't you hide the breath of the real furnace at that time, so why did you say anything about it?"

"Oh. Lu Chen nodded: "Doesn't that mean that if I try to compete with him next time, I can directly exude the breath of this true furnace, and I can directly abolish his Dan furnace?"

"Don't do that. Danzu hurriedly stopped and said: "Dongfang Yu's Taoism is not enough, so he has not sensed the breath of the Bagua True Fire Furnace, if you meet a powerful alchemist, even if you hide it in every possible way, it is very likely that you can see the true fire furnace deity." ”

"Let me tell you the truth, the value of the Bagua True Fire Furnace is comparable to an artifact, before your cultivation is insufficient to protect yourself, don't sacrifice the Dan Furnace at will, it is likely to lead to death, don't think that Danshi can only refine Dan, they are known as the richest cultivators in the world, they have the most spirit crystals in the world, and their cultivation is much more powerful than ordinary people. ”

Lu Chen frowned slightly, nodded and said yes, his cultivation is not more than refining gods, maybe any Dan master can also knock him down to the eighteenth layer of hell, it is indeed better to keep a low profile.

Think about it again, now that he has a variety of magic weapons, plus the soldier word trick in hand, even if he meets a monk who is one realm higher than him, he also has the ability to fight with it, plus the weight of the soldier's mantra, Lu Chen can even kill people by two levels, but thinking about this big week, many Dan masters are already in the realm of stepping on the wilderness, so that Lu Chen needs to at least reach the realm of chaos before he can fight with the monks of the realm of stepping on the wilderness.

Danzu waved with one hand, and a purple Dan furnace appeared in his hand and handed it to Lu Chen: "This furnace is called the Purple Refining Furnace, it is a Ding Xuandan Furnace, I will give it to you, in the future, you will refine the Dan, just use this, gossip real furnace, before you have absolute strength, don't use it indiscriminately." ”

"Master Xie. Lu Chen took the Dan furnace and carefully put it away, looking at Jiang Yi's stunned appearance next to him, Lu Chen smiled, touched Jiang Yi's head and said, "Little junior brother, what do you think of Dongfang Yu's Black Dragon Dan Furnace?"

Jiang Yi immediately swallowed a mouthful of saliva and said, "It's definitely a good furnace, although it's not as good as this purple refining furnace, it's not much worse." ”

Lu Chen laughed and said, "It won't be long before Senior Brother will go and get it from Dongfang Yu and give it to you." ”

"Really?" Jiang Yi looked excited.

"Words count. Lu Chen replied.

In the following time, Lu Chen began to learn the art of alchemy with Danzu in this deep mountain, and this learning was a year.

Danshu is broad and profound, ever-changing, and even if it takes a lifetime to comprehend the mysteries, it will never be learned.

In the past year, Lu Chen has learned a lot from Danzu, and he has a deeper understanding of Danshu, coupled with the assistance of the Bagua True Fire Furnace, Lu Chen's understanding of the mystery of Danshu can be described as a genius, in just one year, Lu Chen can refine the three-grade elixir, and now, he is sprinting towards the four-grade Xuandan, but he has repeatedly failed, even though those top-level alchemy secret methods in the true furnace have been half deciphered by Danzu, Lu Chen still can't refine the four-grade Xuandan.

I learned from Danzu that the Gathering Spirit Pill is the most common and basic kind of pill, which only needs to be refined by spirit crystals, and does not need to add any other materials, so there is no need to control the power of other medicines, which is the basic and introductory in the Dan technique.

Other pills with different effects need to add many special materials, and the mystery of control is also multiplied, which can be described as quite difficult, Lu Chen spent a year refining the three-grade Gathering Spirit Pill, but he couldn't refine the first-grade Alien Pill.

According to Danzu, the top Dan Saint can even refine special pills such as the True Dragon Pill and the Alien Beast Pill, using the Alien Beast as the main ingredient and the Spirit Crystal as the auxiliary, refining the Alien Beast Pill, which can summon the ability of the Alien Beast.

The pill that Lu Chen gave to Danzu a year ago has been studied by Danzu, and it seems that he wants to refine a top-level alien beast pill, but Danzu has spent a year, but he still hasn't been able to refine this pill, which shows how difficult it is.

Now, Lu Chen is not only impacting the four-grade Xuandan, but also studying the refining of the Alien Pill, the Void Pill and the Illusion Pill are also the Alien Pills, but they are all the most basic, and when refining, they need to add some Void Techniques or medicinal materials that change their appearance to refine them.

Although it was just an ordinary elixir, the control of it was much more difficult to refine than the Gathering Spirit Pill, Lu Chen recalled that he had repeatedly obtained the Illusion Pill, which was really lucky.

The sky was dotted with white clouds, and below was an empty meadow, and Lu Chen was sitting cross-legged on the grass like this, with a purple refining furnace levitating above his head.

He carefully controlled the Dan furnace above his head, and carefully refined it according to the secret technique in the Bagua True Fire Furnace, refining the medicine while comprehending.

This time refining, Lu Chen had been refining for seven hundred and forty-nine days, and it was already the last day at this time, and Danzu and Jiang Yi were waiting there, waiting for the elixir to come out.

In the sea of knowledge, Lu Chen controlled the heat of the Dan furnace while using his spiritual power to cover every previous deficiency, and then conjured up the phantom of the Bagua Plate, calculating the auspiciousness of each moment.

This is the ninth time in a year that Lu Chen has hit the Four-Rank Xuandan, and the previous eight times have ended in failure, this time, Lu Chen doesn't want to lose again.

Jiang Yi stared at Lu Chen intently, in the past year, his whole person has become taller, and his body has become a lot stronger.

"Master, can Senior Brother succeed this time?" These days, Jiang Yi has asked Danzu the same question countless times: "The previous eight times Senior Brother failed after practicing for less than twenty days at most, this time he actually lasted to seven seven forty-nine days, will he succeed?"

Danzu smiled and pinched his fingers, looked up at the sky, and replied as if sensing the auspiciousness of this day: "I can't say, Lu Chen is indeed a genius, he can have such attainments in a year, it can already be regarded as quite against the sky, if ordinary people want to have today's creation, it will take at least twenty years." ”

"Can't an ordinary person become a Xuandan Master in twenty years?"

"Hehe, some people can't become Xuandan masters even if they spend their whole lives. Danzu smiled and said, "The hour is coming, I don't know if he can grasp the auspicious time of Xuanguang." ”

"Master, look. Jiang Yi pointed to Lu Chen's side and shouted loudly.

I saw that the purple refining furnace above Lu Chen's head began to spin wildly, bursts of purple qi rushed out, straight into the sky, and in an instant, the black sword flew out of Lu Chen's body and was suspended above the purple refining furnace.

"When Xuanguang is auspicious, the furnace is made with a sword. ”

Lu Chen's tightly closed eyes suddenly opened, and two dragon-shaped purple shadows shot out from the center of his eyebrows, quickly submerging into the Dan furnace.

His whole person flew into the air, wrapped the Dan furnace with divine power, and kept refining it, and when the Ding furnace opened, several purple rays of light shot out, connecting with heaven and earth.

Suddenly, the sky was full of light, and Lu Chen was like a golden-bodied arhat, shining in the air.

"Hey" Who knew that at this time, that Danzu sighed, and in an instant, all the light disappeared, Lu Chen withdrew the Dan furnace and the black sword, and flew down from the air with a depressed face: "Failed again." ”

"How could it fail again?" Jiang Yi was puzzled.

In Lu Chen's hand, there was a purple pill, although it was still fragrant, but it disappointed Lu Chen very much: "Master, you said that when the Xuandan is refined, there will be a vision in the sky, it seems that my Dan has not yet reached the level of the Xuandan." ”

Danzu nodded and said: "When the elixir is refined, there will be a fragrance wafting out, and the birth of the Xuandan will attract visions of heaven and earth, if it is a holy pill, it will give birth to spiritual wisdom, and there are even legends that beyond the existence of the holy pill, it will transform into a human form." ”

"Isn't that a demon?"

"Yes, it's a demon. Danzu explained: "It's not just Dan, you look at those heavenly spiritual treasures, won't there also be spiritual wisdom?"

Danzu comforted Lu Chen and said, "At least, if you fail to refine the fourth-grade Xuandan now, there will be no waste pills, and this pill in your hand can be regarded as a good third-grade elixir." ”

"Yes. Lu Chen nodded, threw the elixir to Jiang Yi next to him, and said with a smile: "Little junior brother, this thing will be handed over to you to study." ”

"Thank you, brother. Jiang Yi took the pill and liked it quite much.

During the time in this deep valley, Lu Chen has been dealing with Danshu almost every day, and if he doesn't understand, Danzu will also teach it humbly, during this period, he has refined the pill countless times, and has realized the mystery of it countless times, although the fourth-grade Xuandan has not been refined, the third-grade and below the elixir are quite thorough, and even from time to time, Lu Chen can also refine the general first-grade pill.

Void Pill and Illusion Pill Lu Chen can occasionally be refined, but the effect is not very obvious, when refining Void Pill, Lu Chen integrated the Soldier Character Formula, and the materials of Illusion Pill are very many here in Danzu.

In the end, the Void Pill was able to make Lu Chen tear the Void and move ten miles, but the Illusion Pill was able to make him roughly change his appearance, during this period, Lu Chen was also improving his cultivation through the spirit pill he had refined all the time, and now Lu Chen was already in the realm of the Great Perfection of God Refining, and it was only a matter of time before he broke through the void.

For more than a year, Lu Chen's gourd already contained hundreds of elixirs, which was definitely a great wealth for ordinary monks, but for a Dan master, it was nothing.

On this day, there were bursts of beast roaring out of the cave where the Danzu Jiuding Dan Furnace was placed, which made Lu Chen and Jiang Yi both startled, they looked at each other, as if they understood something, and quickly flew towards the cave mansion.
