The passage was dark and deep, as dark as ever, with mist and mist floating in it, exuding an unknown and terrifying aura.

"This damn black mist has been devouring my true energy! Fortunately, my cultivation level has now entered the late third-level innate stage from the middle stage of the third level, and my true energy has become much stronger." Ye Xing thought to himself, and his eyes moved.

Looking into the depths of the passage, he immediately stepped forward.

The passage was poorly lit, very dim and narrow, only about one meter wide.

We walked forward, zigzagging left and right, and after about a hundred meters, our eyes suddenly widened.

Ye Xing came to a large dungeon.

The black stone floor, black stone walls and black stone roof constitute this eerie black stone dungeon. The size and layout of the dungeon are the same as the dungeon of Ren Tianxie, the old man in black.

The only difference is that there are no so-called iron chains and shackles in this black stone dungeon. There are only pitch black iron rods connecting the roof and the ground, dividing one third of the corner area of ​​the black stone dungeon.

A small iron prison.

And there was an old man in green robe imprisoned in the iron prison. His green robe was in tatters, covered with dirt and grass blades. His hair was as messy as a chicken coop, and he looked unkempt.

At this moment, I saw that the old man in green robe was looking attentively, writing and drawing on the black stone ground with his fingers, and mumbling something in his mouth.

"This person should be the Yao Lao that Senior Ren said!" Ye Xing's eyes were full of expectation, and he immediately walked forward and came to the iron prison.

"Tianyang flower and Diya grass are the main herbs for refining the Heaven and Earth Guiyuan Pill. But the properties of Tianyang flower are too strong, and the properties of Diya grass are cold. Heaven and earth are separated, and yin and yang are in opposition. If they are forcibly fused together,

I'm afraid these two elixirs will be punished

Waste. Logically speaking, supplementing with starlight fruit can neutralize the medicinal properties of both of them. Why did I only use the starlight fruit supplemented with Tianyanghua and Diya grass to refine the middle-to-low-grade Tiandi Guiyuan Pill?

What is the reason for this?"

Across the iron railing, Ye Xing finally heard clearly what the old man in green robe was talking to himself. He seemed to be studying the formula of a pill.

It's just that he was so focused on his research and thinking that he didn't seem to notice Ye Xing's arrival.

"Junior Ye Xing pays homage to senior, you should be the senior Yao that Senior Ren calls you!" Ye Xing bowed and greeted him loudly.

The sound is not loud, but not quiet either. Logically speaking, it should be audible at such a close distance.

However, the old man in green robe didn't seem to hear Ye Xing's greetings. He was still writing and drawing on the ground, immersed in his own world and studying the formula of the elixir.

Sometimes I think hard, sometimes I meditate, sometimes I frown, sometimes I scratch my head.

"The quality of the middle-to-low-grade Tiandi Guiyuan Pill is too low. I'm afraid half of the medicinal properties of Tianyanghua and Diyaca have not been exerted. Could it be that the medicinal effect of Xingguang Fruit is too weak to neutralize Tianyanghua?

And the cold property of Diya grass?" The old man in green robe began to think hard again, scratching his head vigorously with both hands.

His hair, which was already messy, became even more messy due to scratching and crisscrossing the hair strands.

"Senior Yao, Senior Yao!"

Seeing that the old man in green robe didn't respond, Ye Xing couldn't help but call out twice more.

"That's not right. Starlight Fruit is also a rare spiritual fruit. In terms of rarity, it is not much less valuable than Heliotrope and Diya Grass. It stands to reason that it is fully qualified to be worthy of these two elixirs."

The old man in green robe looked extremely distressed, "But the actual refining effect can only produce less than half of the medicinal properties of Tianyanghua and Diya... this..."

"Hey, by the way, could it be that the medicinal properties of the Starlight Fruit have not been fully exerted?" The old man in green robe patted his head and suddenly realized, and he was extremely excited, "Haha, yes, yes. It must be like this. The medicine of the Starlight Fruit

effect

If only half of it can be exerted, naturally it can only neutralize half of the arachnid. Only with the dew of night sky can the medicinal effect of star fruit be fully exerted, and then fully neutralize the agarwood.

The cold and potent medicinal properties.”

"In this way, we will definitely be able to refine the top-grade Heaven and Earth Guiyuan Pill, and even the best Heaven and Earth Guiyuan Pill is completely out of the question."

As the research on the elixir was completed, the old man in green robe looked very happy, and his heart was filled with a sense of accomplishment. It was like a mathematician had overcome a difficult problem, or a scientist had developed a major invention.

"Hey, boy, when did you come?" The old man in green robe looked at Ye Xing outside the iron prison with a surprised expression. After returning from the world of alchemy, he finally discovered that a visitor had arrived in his dungeon.

"I've been here a long time ago, okay! You just discovered it now!" Ye Xing instantly felt guilty and couldn't help but complain in his heart.

However, Ye Xing did not dare to say such words. He immediately stepped forward and bowed, saying respectfully: "Junior Ye Xing, I would like to pay my respects to Senior Yao. I was introduced by Senior Ren. Senior Ren said that you are the master of medicinal pills."

Wushuang, he asked me to learn the refining method of the Condensing Pill from you, I wonder if the senior can give me some pointers for the junior?"

Ye Xing's attitude was very respectful, and he flattered him without leaving any trace. He was slightly uneasy in his heart. After all, the art of alchemy was extremely precious, and it represented noble status and endless wealth.

"Haha, it's quite rare that the old devil can spit out two good words from his mouth." The old man in green robe smiled and said: "Boy, do you have paper and pen?"

"Yes, yes! I have plenty of pens and paper!" Ye Xing's eyes lit up, he quickly opened the Qiankun bag, took out a large stack of notebooks and handed it to the old man in green robe.

"Well, yes, yes. With so much paper, it will be much more convenient for me to write and draw in the future!" The old man in green robe nodded with satisfaction and asked: "Where is the pen? Pen, ink, paper and inkstone. With just paper, I can write

There’s no way out of this recipe!”

"Don't leave the pen in the notebook." Ye Xing pointed to the ballpoint pens on the notebook and said, "This is called a ballpoint pen, not a traditional brush, but it should be much easier to write than a brush!"

The old man in green robe immediately took off a ballpoint pen from his notebook.

"Where's the ink? Can this pen write without ink?" The old man in green robe looked suspicious and observed the ballpoint pen in his hand curiously.

"You don't need ink. The ballpoint pen has ballpoint ink inside it. Senior Yao, ballpoint pens are different from writing brushes. This is how you hold them for writing!" Ye Xing immediately demonstrated the correct writing posture of the ballpoint pen.

The old man in green robe immediately imitated Ye Xing's writing gestures and started writing.

"Hey, it's really easy." The old man in green robe said in surprise: "How did you make this weird thing? It saves you the trouble of getting ink, it's really a lot more convenient!"

The old man in green robe wrote very fast. He wrote several pages of paper in less than ten breaths. His handwriting was beautiful, between the iron and silver hooks, but there was a vibrant artistic conception in the lines.

"Okay, in addition to the concentration pill, I have written a few more pill prescriptions. You can practice with them first. If you don't understand anything, you can come to me at any time!" The old man in green robe tore off the pill prescriptions from his notebook and handed them to Ye

star.

"Thank you, senior!" Ye Xing looked extremely excited and quickly took the prescription from Yao Lao's hand and started to read it carefully.

The elixir recipe records in detail the formula proportions of various elixirs, as well as the refining methods, precautions and tips, etc.

The first pill recipe that came to my attention was naturally the Taixu Condensing Pill that Ye Xing had always wanted. With the Taixu Condensing Pill, my mental power would be able to increase rapidly in the future, and the speed of practicing martial arts secrets would definitely increase by leaps and bounds.

"Great, I can finally refine the Taixu Condensing Pill. I'm looking at other pills. This senior medicine man is very nice. In addition to the Taixu Condensing Pill that has been extinct in the martial arts world, he also prepared a few pills for me.

Practice with other ordinary elixir recipes!"
