Xiannongyuan’s way of doing things is indeed different from other sects. They seem to be easy to trust others and easily gain the trust of others.

Su Yu just made a verbal guarantee, and Mrs. Cheng took out most of her spiritual medicine without saying a word to prepare for Su Yu's rebirth pill.

Little did they know that this natural behavior had won Su Yu's favor, and this would be of great benefit to all activities in Xiaju Cave Heaven in the future.

Su Yu sat aside and watched. Mrs. Cheng was not afraid that Su Yu would see the pill recipe and refining process of the rebirth pill, because many of the formulas of the rebirth pill are finished medicines, that is, the spiritual medicines that have been refined.

What is the function of the Resurrection Pill? Mrs. Cheng knows better than anyone else, so she deliberately speeds up the pace when refining. Saving people is like putting out a fire. She doesn’t have so much time to prepare.

In the three-legged cauldron in the house, purple fire burned. Mrs. Cheng added spiritual medicine step by step in order, and during this period, she also put pieces of purple spiritual wood into the fire.

Su Yu could see that this purple wood was used to renew fire, and the essence of the flame was much worse than that of his own white flame, so he asked: "Madam, the more the essence of the fire, is the greater the chance of success in refining?"

Mrs. Cheng picked up a scarf and wiped the sweat from her forehead, nodded and said:

"Yes, among the five elements, wood produces fire. The most exquisite fire often comes from wood-based refining tools. Once the purple wood at my hand is burned, there will be no residue. It is considered a very high-quality fire-induced object. Fire produces gold. This is why the earliest elixirs refined are defined as golden elixirs. The higher the essence of the furnace fire, the more beneficial it is for refining, it will be without any harm."

Su Yu nodded, raised his wrist, and a white flame suddenly rose up at the tip of his index finger.

"Mrs. Cheng thinks that my fire is suitable for making fire?"

"ah......."

Mrs. Cheng is the master of fire control, so she can naturally see the white flame on Su Yu's hand at a glance, which is the essence of fire and is the most suitable for use in fire.

Although I don’t know how Su Yu was so capable, I would undoubtedly raise the evaluation of Su Yu several steps deep down.

"Nothing is more suitable than the Blazing Fire,"

After being surprised, Mrs. Cheng hurriedly opened the furnace lid, Su Yuyi understood it, and in a flash of her fingers,

The moment the white flame entered the furnace, it instantly burned the purple fire into nothingness.

Fire burns fire.

The purple blue smoke that originally rose from the cauldron turned into a faint white at this moment.

The first furnace, failed,

The second furnace is almost successful.

The third furnace is almost a semi-finished product.

Fourth, fifth, sixth, all failed.

Just as Mrs. Cheng was anxious that the spiritual medicine was about to be used up, Ciyin arrived in time and threw a large package of spiritual medicine on the table.

Mrs. Cheng was so shocked that her chin was almost falling off. How could there be so many? Who is this little girl? Judging from her appearance, she seemed to think these elixirs were very ordinary.

"Brother, what is she doing?" Ciyin sat down obediently next to Su Yu, holding her cheeks and staring at the furnace.

Su Yu rubbed the child's head and smiled, "This lady is helping the prince to refine medicine. The prince needs to use this medicine to save people."

"Refining medicine?" Ciyin frowned and said, "Is this how it is used to refining medicine?"

Su Yu nodded and said, "Of course."

Ciyin shook her head with a strange expression:

"It is right for the cauldron to be grounded, but it is wrong on the tree. Besides, the fire does not borrow power, so there is no fire power, and the chance of failure will be very high. Moreover, she sent the spiritual medicine directly into the fire. This way, the medicinal power will not be pure. Shouldn't it be necessary to temper the spiritual energy in the spiritual medicine in advance?"

Su Yu was stunned when he heard this, turned to look at Mrs. Cheng, who looked completely confused.

Because she couldn't understand what Ciyin was saying.

So Su Yu relayed Ciyin's words just now,

After hearing this, Mrs. Cheng was dumbfounded: "Miss actually knows how to cultivate alchemy?"

Ciyin shook her head: "I don't understand, but I have seen it a lot. You are ruining things when you refine it like this."

Su Yu recounted it again.

Mrs. Cheng was stunned, fell into silence, and after pondering for a while, she said:

"The little girl is right. If the cauldron is not connected to the ground, it requires a Taoist secret technique to mark the foot of the cauldron into a private land that is stripped out of the heaven and earth. This secret technique is a secret secret that the Taoist sect does not pass on, and I don't understand it. The so-called "take advantage of the situation" is to borrow the wind. This wind is not an ordinary wind, but a rootless wind that does not know where to come and go. I only know the reason, but I don't know where to borrow it."

"As for peeling off the spiritual energy from the elixir and then sending it into the fire, this is of course the most ideal. Unfortunately, my realm is not enough to be able to do it."

Ciyin held her chin and pondered for a moment, then looked at Su Yu: "Brother, why don't you let me try it. How good is her level not as good as mine?"

Su Yu did not translate this sentence, so as not to hurt Mrs. Cheng's self-esteem.

Whatever Child Ciyin does, she has always been extremely reliable, and Su Yu completely trusts this.

If the child hadn't said what he said just now, Su Yu really didn't dare to let her try, but now he is in a hurry to seek medical treatment. Anyway, Mrs. Cheng always fails.

"Are you sure?" Su Yu asked.

Ciyin smiled and said, "Just look at the medicines on her desk, I guess the ones that have been refined are not high-quality pills. I can guarantee success once, so don't worry, brother."

This child... is always so popular, Su Yu said happily: "It's not too late, you can get started."

"Brother, I'll prepare some things later, it'll be fine in a while."

After saying that, Ciyin plunged into the ground with her head.

After a while, Ciyin came back, and she saw a serious expression on her face, holding a light golden branch in her hand.

"The prince moved the tables away and made room."

Su Yu raised his hand and whipped it, and the miscellaneous items on the table scattered, and a large piece of open space in the center was immediately released.

I saw Ciyin pick up the branch, lie on the ground, and start to gesture quickly.

Su Yu and Mrs. Cheng stood in the corner, both of them with surprised expressions.

In a moment, a complex pattern of a circular and hexagram in the center appeared on the ground. When Ci Yin was drawn, the branch in his hand just happened to be used up.

"Hehe, yes, no stroke is wrong," Ciyin clapped her hands with a smile, "The prince moved the cauldron to the center of the rune."

Su Yu did as he said, and cooperated completely to start.

When the cauldron was just moved to the center of the pattern, the three thick furnace feet suddenly left the ground, only half an inch from the ground, but they were floating above the runes as steady as Mount Tai.

The original ink-colored cauldron suddenly turned into bronze, showing a sense of ancient vicissitudes. The countless runes engraved on it are now hidden in the rays of light.

Mrs. Cheng was stunned, unable to bear to blink, staring at Ciyin's movements in her hand for a moment,

"Brother, fire,"

Ciyin opened the cauldron, and Su Yu bounced his finger and sent out a white flame.

"Warm the furnace first, and wait until the yin and yang energy is produced in the furnace, then it is time to release the spiritual medicine."

Then, Ciyin took out a small blue and white porcelain cup, without any guidance from Mrs. Cheng, and arranged the order of tempering the elixirs in no way.

Then Su Yu guided the spiritual energy from the spiritual medicine bit by bit and sent it into a small blue and white porcelain cup.

Ciyin held the small cup, staring at the flames in the furnace and murmured:

"There is a universe in the furnace. In the small world in the furnace, all things run according to their way, water and fire complement each other, and yin and yang are harmonious."

"alright,"

Ciyin opened the small porcelain lid and sent the spiritual energy into the furnace in one breath. She looked at Su Yu with a smile:

"The fire leverages the momentum to activate the time in the furnace, causing the stars to change and time to fly. This is what is called a ten-year-old elixir, and a hundred-year-old elixir. In fact, it depends on whether the borrowing is good or not."

Su Yu nodded repeatedly, "Well, yes, you're right."

Ciyin smiled sweetly and took out a palm-leaf fan.

The fan in her hand seemed to be made of some grass and trees. It was yellow in color, and it looked a bit old and relatively worn.

But Su Yu knew that this fan was definitely not simple.

Sure enough, Ciyin raised her hand and waved her fan, and a breeze visible to the naked eye was sent into the furnace.

For a moment, the fire in the furnace rose up.

Above the cauldron, thick white light smoke rose up instantly like clouds, and a strong fragrance of medicine instantly filled the house.

Seeing this, Su Yu hurriedly led the dan fog out of the house. For a moment, the woods were filled with mist and clouds.

The disciples of Xiannongyuan stopped their movements at the same time and looked at the tree house in surprise.

"Master's wife has made great progress in her alchemy skills. Oh my God, this pill fragrance is so strong. I'm afraid this time it will be a furnace of ground-grade spiritual elixirs."

"It's worthy of being a master's wife, it's so amazing."

"I have refined the earth-grade spiritual pill. Will he dare to look at us with his nostrils in the future?"

In the tree house, Ciyin put away the fan after swinging it three times in a row and said:

"No, this pill can't stand the wind anymore. Next is to go to the Fire Condensation Pill. Brother, please drain the fire bit by bit, remember to slow down."

Su Yu nodded, "Okay."

When the white flames in the furnace were absorbed by Su Yu, no smoke rose on the cauldron, but the fragrance of pill became more and more intense.

I saw Ciyin standing in front of the cauldron, pinched out a strange magic formula with both hands, and shouted in a low voice:

"Yin and yang are pure, add oil to life, add three grades of medicine, spirit and qi essence, install the furnace and set up the cauldron, gather and refine the Quanzhen,"
