"The reason why the fire heart is burned first is because when I checked the Dan furnace, I found that the Dan furnace has fallen into disrepair, and the furnace wall has become thinner, making it difficult to maintain heat, so it must be heated first so that it can reach a normal temperature when the medicine primer is added. After speaking, Shi Mu walked over from the door frame of the back chair and touched the Dan furnace.

"I see! I said why do I follow the correct steps every time to refine, but I can't refine it every time, it turns out that the temperature is not enough! It's really confusing!" Huoxin slapped his head, unable to complain about his stupidity, he only knew how to read from the script, but he didn't know how to improvise, and he didn't know how long he stayed in this step.

Gu Shan behind him couldn't help but lower his head, he didn't find such a simple question as the Dan Emperor, he was really ashamed.

Ignoring the self-esteem of the two of them, Shi Mu found a chair and sat down, crossed Erlang's legs and continued, "As for the last medicine, the reason why the water tail grass is chosen instead of Luohezi is because this Luo Shen Dan is a water attribute pill, and the main ingredient in the herb is the water element, so the water tail grass can naturally play the same role as Luohezi, and the second reason is ~~~"

"Oh!" "I understand!" Before Shi Mu could say the second reason, Gu Shan suddenly opened his mind and shouted excitedly, "The second reason is also related to the Dan furnace!"

Only Huoxin was left alone in the field, so he didn't know, "Master, what are you talking about?" I don't understand, it stands to reason that Luohezi is more than the watertail grass of the watertail grass, there should be no reason to replace it, even the watertail grass is also a water attribute, but the water elemental spiritual power that Luohezi can provide for the Luoshen Pill is far more than the watertail grass?"

"Silly apprentice, isn't it because of your broken Dan furnace? Oh no, you... You... Your ancestor has said that the walls of your Dan furnace are thin and can't retain the temperature, and Luohezi not only has water attributes, but also contains a large amount of ice attributes!

After speaking, Gu Shan looked at Shi Mu embarrassedly and asked, "Master, hehe, is what the apprentice said right?"

"Well, the child can be taught, haha" Shi Mu looked at this bad old man and was quite modest in his quest for knowledge, and his heart was also happy, and he laughed and said, "Actually, do you know? This Luo Shen Dan originated from..."

"Hey, little brat, it's almost there, if you don't say anything after a while, you'll start inking!" Ling Yu'er couldn't complain about Shi Mu's verbosity, and any thing could start from the origin of 100,000 years ago, and there was no one.

"Oh, haha, don't talk about this, since the apprentices and grandchildren are so obedient, I'll give you a gift for the teacher~" After speaking, Shi Mu picked up the pen and paper and began to wave.

"Oh?" Gu Shan and Huo Xin watched curiously as Shi Mu waved on the paper, not knowing what he was writing.

I saw that the wooden pen was strong and powerful, the pen walked the dragon and snake, and with the brush back and forth on the paper, there was a whirlpool of aura in the space!

And at the center of this vortex is precisely that piece of paper.

"Gushan, Huoxin, are you ready?" Shi Mu asked as he looked at the two of them with a wicked smile.

"Ah, what are you going to prepare?" Master, "Gu Shan and Huoxin looked at me with a blank face, I look at you, I don't know what it is.

Before the two of them could react, they saw that Shi Mu had stopped writing, and the moment he put down the pen, a red light suddenly appeared on the paper, illuminating the entire three layers.

Immediately afterwards, the weather outside the window suddenly changed suddenly!

The sunlight in the house suddenly turned cloudy, without a trace of light, what a few people didn't know was that at this moment, the birds and beasts outside the Baicao Hall had been scattered, and the people had already fled in all directions, and outside the range of the Baicao Hall, there were dense crowds of people around them. At the same time, they were chattering.

"I'll go! Look, this is the Heavenly Tribulation! The red Heavenly Tribulation! It's the first time I've seen it!"

"yes, what kind of person is this to break through in the city?

"That's it, is this for the whole city to bury him? I really hope this thunder will kill him!"

"Ahh

The ancient mountains and fire hearts in the house also felt this strangeness, and said in unison: "Dan Tribulation!"

After a powerful pill comes out, it will definitely break the balance of spiritual power distribution in this world, which is intolerable by heaven, and the sky will descend on the heavens to eliminate it!

But looking at the four-grade and five-pattern Luoshen Pill in his hand, Huoxin didn't feel the slightest echo of spiritual power, could it be!

Considering this incredible possibility, the two of them put their eyes together on the restless piece of paper in the room at this moment, seeing that it was red and shining, as if it echoed with the Heavenly Tribulation, resisting each other, if I didn't guess wrong, this Dan Tribulation was coming for this piece of paper!

"Look at your appearance, have you guessed it?That's right, this Dan Tribulation is for the Dan Fang I just wrote, hehe, whether you can take this Dan Fang for a while, it depends on your performance~" After speaking, Shi Mu's consciousness sank into the sea of knowledge and exchanged it back to Ling Yu'er.

"What! This Dan Tribulation is aimed at Dan Fang!" Gu Shan couldn't say it all.

He has lived for more than two hundred years, the level of the pill is more than six grades, the quality is more than five lines, and it will usher in the red pill tribulation, he has not heard of it, although he has never seen it, but a pill recipe actually angered Tianwei!

What kind of anti-heaven pill is this! Could it be a seven-grade or even eight-grade pill?

Thinking of this, Gu Shan's forehead had already begun to sweat wildly, completely frightened by everything in front of him and his own conjecture.

Hurriedly looked at the fire heart on the side and shouted, "Silly apprentice, what are you still doing in a daze! Hurry up and release the spirit technique! Protect this Dan Fang!"

"Oh! I know, Master!" Huo Xin didn't have time to hesitate, and hurriedly propped up a fiery red defensive light curtain above the room with both hands, and Ling Yu'er on the side who was pressed by the momentum of the Spirit King's peak that came out of his body hurriedly ran the Heavenly Dao Refining Body Determination to resist.

Gu Shan did not hesitate, and took out a disc-shaped spirit weapon from the space ring and controlled it in the air, and the moment it was intertwined with the fiery red light curtain, the ability burst out instantly, and the light curtain was thickened by I don't know how many layers.

Even so, the two of them did not relax in their expressions, staring at the Dan Tribulation that could attack at any time on the ceiling.

And Ling Yu'er on the side, the spiritual power consumption of this day has already been overdrawn, and all the remaining spiritual power in his body is used to run the Heavenly Dao Refining Body Decision.

"This Shimu little fart, don't let me know in advance what you want to do! If the master sells this today, you can wait to stay in the ring for the rest of your life!" Ling Yu'er complained helplessly.

At the same time, in a certain corner of the Tianwu Continent, a middle-aged man wearing a black robe and asking a nine-layer Dan furnace pattern on his left shoulder looked at the sky, his brows furrowed slightly, and he muttered to himself, "Dan Tribulation, it seems that I have to go, Tianwu Kingdom!"

Similarly, the crimson Dan Tribulation suddenly condensed at the foot of the dignified King City, which naturally alarmed the master of this realm, Bai Yi, the king of the Heavenly Martial Kingdom!

"My poor boy, for my father, I will avenge you! If you dare to touch my Tianwu Tianzi, I will definitely want him to connect the nine clans!" After speaking, the man clenched his fists with both hands, clenching his fists to the point of clucking. The person who spoke was dressed in a golden dragon robe, caressing the unconscious white-haired young man on the luxurious bed, his eyebrows furrowed, and his eyes were full of anger except for a little sadness.

"Meet Your Majesty, meet the Three Princes! Qi Your Majesty, a red heavenly tribulation has appeared above the Hundred Grass Hall!! The evacuation of the personnel has been completed, and then we will all listen to His Highness's arrangements!" A silver-armored guard hurriedly rushed into the Third Prince's Palace, and said eagerly.

"Red Heavenly Tribulation? Dan Tribulation!" Bai Yi jumped up directly from the side of the bed in surprise, came to the outside of the house in an instant, turned to the guards in the palace and said, "Immediately gather all the Spirit Emperor Marshals in the Imperial Palace! Hurry to Baicao Hall!" After speaking, the spiritual power operated, and a silver long sword under his feet soared into the air, and disappeared in front of the guard's eyes with a whoosh.

"Hahahaha!Dan Tribulation!Baicaotang Dan Tribulation!Hahaha," Bai Yi laughed as he galloped in the air.

"Dan Tribulation, it means that at least the five-rank pill has come out! It must be the old man of Gushan! Haha, if there is one more five-rank pill master in the country, then those few beasts who are eyeing me will no longer be my Tianwu opponents! This Tianwu Continent will be my Bai family sooner or later! It is really my Tianwu's luck! Hahaha"

As he spoke, another spiritual power was injected under Bai Yi's feet, and the Lone Moon Sword suddenly sped up, speeding towards Baicaotang, and in his field of vision, several small black shadows who were rushing quickly followed.
