Elder Li is still Elder Li, and he will always have that angry temper.

Ling Yi, who was dragged by him and staggered away, couldn't help but roll his eyes, he couldn't figure out how Elder Li was so anxious to do the matter of alchemy.

As soon as the fire was about to pass, he easily let go of Ling Yi's sin of making him wait stupidly all night, in Elder Li's heart, punishing Ling Yi was far less important than his own furnace of elixir.

I have to say that although he was still wary of Elder Li, Ling Yi also admired his persistent attitude.

The people who can do one thing to the extreme are all masters from all walks of life, and Ling Yi believes that Elder Li is this kind of person.

Entering the thatched house, just like last time, Elder Li pulled Ling Yi to open the mechanism, and the two of them entered the Dan room built underground together.

The stairs leading to the Dan Room were only halfway through when Ling Yi felt a wave of heat surging from below, and he could already see a fiery red light flickering at the end of the stairs.

When I really walked into the Dan room, I saw that the alchemy furnace in the middle was already raging.

Elder Li sniffed vigorously, carefully distinguishing the smell of medicinal herbs coming from the furnace from the scorching air, and then nodded with relief, "It's okay!"

If it weren't for the fact that he couldn't leave last night with the half-refined medicinal materials in this furnace, Elder Li would have wanted to rush to Ling Yi and beat him up.

"Here, let's get started!"

Elder Li let go of Ling Yi's hand, walked to the Dan furnace by himself, looked through the observation hole, and then grabbed another handful of medicinal materials that had been prepared next to him, and with a wave of one hand, the internal force gushed out, and the lid of the furnace was lifted by him.

The herbs were accurately put into the Dan furnace, and when I heard a bang, the lid of the furnace was tightly closed.

This handful of medicinal herbs was thrown in, and I don't know how it worked, but the blazing fire was actually suppressed a few points at this time.

Ling Yi's feeling here was more direct, and he obviously felt that the temperature in the Dan room had also dropped a lot because of this.

"It's your turn. ”

Elder Li turned his head to look at Ling Yi.

"Master, what should the disciple do?"

The light of the fire in the furnace was reflected in Ling Yi's eyes, just enough to hide the fact that he had opened the Red Fire Pupil.

Long before entering the Dan Room, Ling Yi had always kept the red fire pupil open, silently observing all the details around him, once he found that there was something unfavorable to him, Ling Yi was ready to say nothing, turned around and was about to run.

However, everything was quite normal now, and with his own safety ensured, he didn't mind helping Elder Li refine the pill.

However, Elder Li's next sentence suddenly made the situation less normal.

"It's very simple, you first squeeze out a drop of your heart blood and drop it into the furnace. ”

Elder Li commanded as a matter of course.

"Bloody?"

Ling Yi was shocked.

Heart blood, also known as heart blood, is the essence of everyone's heart, the purest source of essence blood, once the heart blood is lost, the light will be a serious injury, and it is not impossible to die on the spot.

Elder Li's mouth is to take his heart's essence and blood?

Although it was only a drop, Ling Yi could resist it, but how to get this effort?

Could it be that he took a knife and cut open his chest and pinched his heart directly to squeeze blood?

"Why are you stunned, squeezing blood!"

While Elder Li was taking care of the Dan Furnace, seeing that Ling Yi was not moving, he couldn't help but urge urgently.

"I ...... The disciple didn't know how to squeeze out the essence of his heart. ”

Resisting the urge to turn his head and run, Ling Yi replied honestly.

"I don't even know this, how did your master teach you?"

When Elder Li heard this, he immediately blew his beard and glared angrily.

"Then you have to ask my master. ”

Ling Yi was speechless, spread his hands, and looked at Elder Li with a sincere face.

Isn't this just his master?

Elder Li patted his head, he was also in a hurry.

"Boy, listen to me......"

Glancing at the Dan Furnace, Elder Li, who knew that he couldn't wait for a long time, hurriedly said to Ling Yi, and at the end, he asked urgently, "Is it clear?"

"This ...... It's clear, but Master, if you squeeze out your heart's work, it will damage your disciple's vitality a lot!"

Ling Yi was not in a hurry, and said slowly, looking embarrassed.

"Humph!"

How could Elder Li not understand his careful thoughts, and he was not ambiguous, he directly threw out a pill, and snorted angrily: "Is this enough to compensate for your loss?"

Ling Yi raised his hand to take it, but before he could understand it, Elder Li's words followed, "What, don't you know?"

"Didn't you tell people everywhere that the apprenticeship gift that the old man gave you was a fifth-level pill bone cleansing pill?"

"This is ......" Ling Yi was overjoyed when he heard this, and couldn't help but be surprised: "This is the Bone Cleansing Xuandan?"

Elder Li sneered and teased, "Haven't you eaten it all?"

"Hey...... Isn't that a disciple unwilling to weaken your alchemist name Master outside!"

Ling Yi pretended not to understand, and also believed that Elder Li would not casually take a pill to deceive him, and while laughing, he took out his medicine bottle and put the Bone Cleansing Pill into it with great dignity.

"Can we begin?"

Elder Li was already impatient.

"Yes, yes!"

Getting a fifth-level pill as a reward, Ling Yi was full of energy, just a drop of hard work, and getting a fifth-level pill was enough to make up for his shortfall.

He didn't hesitate at the moment, according to the method taught by Elder Li, wrapped the meridians around his heart with internal force, and then simulated the action of squeezing, and slowly pressed his heart with internal force.

Suddenly, a sharp pain came, and Ling Yi's face suddenly turned a little pale, but a drop of essence blood in his heart was also squeezed out of his heart by him, carefully protected by that internal force, and flowed all the way to the ring finger of his left hand along the Sanyang meridian of his hand.

Elder Li had already prepared, and in the morning, his fingers were bloody, and a silver needle immediately pierced it.

His silver needle was hollow, and this thorn not only pierced Ling Yi's ring finger, but also sucked that drop of heart blood into the needle, and carefully took it out.

Only then did he wave his hand again, the lid of the furnace was lifted, Elder Li raised his hand, and Ling Yi, who had inhaled the silver needle, was impartial and flew into the Dan furnace.

Thereupon......

Boom ————!

The huge red flames rose into the sky, and the momentum was so strong that the ceiling above the two of them was filled with a rolling heat wave, and it looked like a sea of fire was floating above the two of them.

This drop of hard work was more than ten times stronger than the blood effect that Ling Yi casually made at the beginning, the alchemy furnace was no longer visible here, and all that could be seen was a huge pillar of fire.

"Qiangang Soul Devouring Fire, it's really powerful!"

Elder Li was stunned for a while, and praised it in his mouth, only then did he come back to his senses, and hurriedly threw the medicinal herbs he had prepared and put aside, including the five-colored grass, into the pillar of fire, and began to chant words in his mouth, constantly pinching his hand and calculating something.

At this moment, Elder Li's expression was extremely focused, as if he had forgotten that there was a person like Ling Yi beside him, and his whole body was devoted to the huge red pillar of fire in front of him that seemed to be able to incinerate everything in the world.

But Ling Yi's body trembled violently at this moment, and his face was even more red.
