Seeing Li Chong walking out of the secret room, he came to the entrance, and returned the jade plate to the secret room.

Inside the jade plate are ten plants that look like they are about to wither, it is the withered heart grass that Li Chong has been looking for for a long time, in the Fallen Holy Land, he originally said that he could ask Zhao Yunyan for the withered heart grass, but at that time, Li Chong, who was originally there for this under the life-and-death situation, forgot about it.

"Hey, hey, it's just the right time, Li Chong, I'll teach you the alchemy now, due to the limited time, the purple spirit pill must be refined as much as possible!"

"Now, but I have never been in contact with the art of alchemy, there are only two pieces of purple spirit flowers, and if you fail once, it will be less than half, if you fail twice, you won't even think about the purple spirit pill" Li Chong frowned a little.

"Wrong! There are no two times, only once, two pieces of purple spirit flower are the minimum requirements for refining the purple spirit pill, the medicinal effect of the purple spirit pill successfully refined is several times that of taking the purple spirit flower alone, if it is only one piece, there is not much medicinal effect at all, so I decided to refine two pieces at one time, there is only one chance!"

"Are you mistaken, big brother! Desperate, even an alchemist at the level of an alchemist at the level of an alchemist does not dare to say that he is absolutely sure that he will succeed in refining an elixir that has never been refined at one time, not to mention that I am still a person who has never had experience in refining pills" Li Chong immediately almost burst out, staring at the Decepticon and shouting.

"What is an ordinary alchemy master, I am a real alchemy master, rest assured, I have absolute confidence that I will refine the purple spirit pill at one time, don't worry, first of all, I will tell you the way of alchemy.

"Alchemy, alchemy, what else to say, I don't know if it's only seven days," Li Chong said impatiently.

"You are wrong, the way of alchemy is the foundation of alchemy, if you don't understand anything, then 100% will fail in alchemy" Speaking of the way of alchemy, Batian suddenly had a grandmaster demeanor, looking at Li Chong with a serious look.

"If there's a fart, let it go!" Li Chong was directly speechless and said impatiently.

Batian didn't bother with Li Chong as before, but spoke silently.

"To make a long story short, alchemy is actually a means of neutralizing the medicinal properties of the elixir, and every elixir bred between heaven and earth contains innate medicinal properties, which is why a medicine can be used to treat a disease so targeted."

"The medicinal effect of each elixir is different, and the nature is not unique, some elixirs are rich in a variety of medicinal properties, some of these medicinal properties may be very useful to monks, and some may not only be useful but fatal, and alchemists are professionals who neutralize these medicinal properties, they are generally very familiar with the medicinal properties of many elixirs, so as to refine the elixir that is only good for the monk and has no harm."

"I know what you said, let's talk about the key" Looking at Batian and saying one by one, Li Chong was very helpless, he had already understood these big truths, so it didn't matter if Batian said it or not.

"You stinky boy! Since you say so, then I'll say something you don't know, there are many kinds of alchemy methods since ancient times, including water refining, fire refining, thunder refining, and other refining methods, each different alchemy method has its own different advantages, but it has been passed down to the present day and is basically a habitual method of using fire refining."

"Hmm, isn't alchemy all about refining with fire, how can there be so many refining methods you said?" Li Chong asked with some puzzlement, he had only heard of refining pills with fire, and he really hadn't heard of anyone refining pills with water, thunder or something.

"Don't you know everything?hahaha, why don't you know now?" said Batian with a smug smile.

"Who knows what the hell you said, I'm a modern monk, and I'm not an old antique like you," Li Chong pouted.

"Whether it is water refining, fire refining, or even thunder refining, it is actually the same, it is all through guò aura to remove the impurities in the elixir and some medicinal properties that are unfavorable to the monk, leaving it beneficial to the monk."

"Then what kind of alchemy method are you good at?" Li Chong asked with some curiosity.

"I—I said I'm good at refining my own methods, do you believe it or not?" said Batian, who began to boast again.

"Just blow it, you, just your spirit, my master just releases you every day, and you can't learn so much," Li Chong shook his head in disbelief.

"If you don't believe it, sooner or later you will know, okay, let's go on to say that there are five points that are particularly important in alchemy, one is the Dan prescription, the second is the medicinal materials, the third is the Dan furnace, the fourth is the divine sense, and the fifth is the environment."

"So complicated?"

"Of course, the Dan recipe is the method of refining, not to mention the medicinal materials, the Dan furnace is a necessary alchemy weapon, the divine sense control is the key to the success of refining, the environment is also very important, there is no distraction in the alchemy process, otherwise the previous efforts will be wasted. Batian explained very strictly, and Li Chong remembered these five points vividly.

"The Dan Fang of the Purple Spirit Pill has already told you, and you have prepared all the materials, the Dan furnace is ready-made here, your divine consciousness contains green lotus in the sea, and there are many mysteries in the divine sense, in terms of alchemy, it is simply a congenital gift, and you don't have to worry about the environment, the only thing you lack is experience, this experience is not something that can be taken shortcuts, it needs to be continuously accumulated, but you can also rest assured of this, because there is an alchemy master right in front of you."

"Grandmaster, where is it, why didn't I see it?" Li Chong said with a snort, looking around.

"I'm blind to you, I'm the one who deceives you."

The five secret rooms are not large, each of them is only more than fifty zhang wide, but the breath exuded by each secret room is different, which is the breath of the five elements of gold, wood, water, fire, and earth, and this secret room is obviously specially prepared for monks with different spiritual roots of the five elements.

"Oh, it seems that you have put a lot of thought into the arrangement of this secret room" After seeing the five secret rooms, Li Chong's eyes lit up, and in the five secret rooms, he clearly sensed the fluctuations of the aura of the five elements of gold, wood, water, fire, and earth, especially the metallic and fire attributes, and the ** he majored in were these two attributes, so he was particularly sensitive.

"This is the small Yuan Gathering Five Elements Array specially arranged here by the predecessors of my Heavenly Sword Sect, not only can it absorb the different spiritual energy of the five elements, but the five small formations can also form a large array, absorbing a large amount of the spiritual energy in the Nine Elements Gathering City" Guo Yu explained, saying that this small Yuan Gathering Five Elements Array, a touch of pride appeared on his face.

"The formation is a good formation, but unfortunately, even if it can forcibly ingest the aura, it is empty talk in this era of lack of aura, compared to before the shattering, this aura is not even a fart at all" Ba Tian said with some disdain, he has always been a master and a low eye, and he doesn't pay attention to these.

"These five secret rooms were originally reserved for my disciples with outstanding achievements in the Heavenly Sword Pavilion, but now since the seniors want to borrow them for a few days, then from now on this place is a forbidden place, and the seniors can retreat again, and I will send you as soon as the things you want arrive."

"Okay, you can step back, by the way, don't let people know that I'm here, otherwise I won't be responsible for causing trouble, just put the things I want at the door of the secret room, don't bother me" Li Chong nodded, and then reminded.

"Senior, don't worry, I will definitely restrain the tongues of my disciples," Guo Yu promised, and then turned around and left the fifth layer.

"Wow, I didn't expect to be so tired of pretending to be a master!" Seeing Guo Yu walking away, Li Chongchang breathed a sigh of relief. Then he walked into the secret room with the strongest fire attribute aura.

"Hey, hey, hey, although it's faked, but you kid has a lot of benefits!"

"One hundred thousand spirit stones, my one hundred thousand spirit stones!" Li Chong shouted, he was not going to give so many spirit stones to Guo Yu, but Batian reminded him at that time that he must give them, Li Chong's heartache at that time, what made him most uncomfortable was that he had to pretend to be very indifferent when he gave 100,000 spirit stones.

"Okay, put a long line to catch a big fish, why are you in a hurry, besides, the spirit stone is not yours, it's okay, the things I listed are worth far more than 100,000, you have to treat people like Guo Yu with both soft and hard, otherwise it will not be good to show the stuffing" Batian persuaded him.

Li Chong thought about it and felt that it was also, anyway, it was not his own spirit stone, there was nothing to be reluctant to, and after thinking it through, he took a good look at the secret room in front of him.

The temperature of this secret room is very high, several times higher than that of the outer door, if it weren't for Li Chong's cultivation of the fire attribute Burning Sky Fire Spirit Technique, he would not be afraid of fire but very friendly, even he would not be able to stand it.

There are not many things furnished in the secret room, except for a ground fire vent in the center and a half-zhang high alchemy furnace, the whole secret room looks very empty.

"This is too ordinary, isn't it, just a broken furnace?" Li Chong glanced at the entire secret room with some disdain.

"It looks simple, it's not like the ordinary on the surface, the walls are carved with formations, in addition to the spirit gathering array, there are also dozens of formations such as sound insulation array, meditation array, cold spirit array, fire gathering array, protection array, short-distance perspective array, etc., the people who have seen this arrangement of the secret room have indeed spent some thought" Li Chong's body Burning Heaven Ding fragment flashed, and then the illusory figure of Batian came out of it, and Batian looked at the secret room with praise and said.

"How can you see so many formations?" asked Li Chong with some puzzlement.

"Hmph! I said that I have all grandmaster-level attainments except for the Heavenly Machine Technique, and you still don't trust me," Batian said very proudly.

"Cut! hahaha, but I still don't believe it!"

"Good !!, I'll let you see my alchemy attainments next!" Batian was very unwilling to distrust Li Chong, and as he was talking, a bright light suddenly flashed on a place on the wall of the secret room, and then a picture appeared in front of Li Chong and Batian.

The picture is the entrance to the fifth floor of the Heavenly Sword Pavilion, that is, the entrance not far from the five secret rooms, at this moment, there is a very beautiful-looking female cultivator who came here with a jade plate, so the female cultivator looked around, put the jade plate at the entrance, and then retreated tremblingly.

Seeing Li Chong walk out of the secret room, come to the entrance, and return the jade plate to the secret room.
