The alchemy house in Zuo Ningshan is not far away. When Liu Zhuo and Lao Yu came to the alchemy house with the materials in hand, Zuo Ningshan had been waiting for a long time, or in other words, Zuo Ningshan had not left the alchemy house for half a month.

Liu Zhuo looked at it curiously.

The entire alchemy room is extremely huge, and it seems very empty. In the center is erected with three legs in the bronze alchemy furnace, which is full of cold air from afar. Obviously, this alchemy furnace is not an ordinary product.

Under the alchemy furnace, an old man with gray hair, tall figure and very wide shoulders were sitting cross-legged, with a chess table in front of him, with two black and white sons on it. The old man's face was born with seriousness, and now he was focused, holding a chess book in his hand, and he was stunning.

Old Yu was no longer surprised. He walked up to salute and said, "Uncle Zuo, the materials for refining the Gu Ling Pill are ready."

Zuo Ningshan slowly lowered the chess score at this time. He stood up and glanced at the two of them, then turned his eyes to the alchemy furnace in front of him, and said, "You have no convenience in your left hand, so let the disciples next to you take care of the heat, you can go back."

Lao Yu nodded respectfully, put down the materials, and then left the alchemy room.

At this time, Liu Zhuo was looking at the curious eyes. The old man in front of him, who was said to be almost two hundred years old, couldn't help but feel uneasy.

He had heard other disciples in the Medicine Collection Hall discuss that this serious Master Zuo had already practiced the basic skills to the top, and was at the thirteenth level of the Qi Refining Stage.

The one he is best at is the fire magic. In addition, his elixir skills are extremely clever. Most of the pills in the Five Mountains Sect are written by him, so in the eyes of many disciples, he has a very high prestige.

Zuo Ningshan glanced at Liu Zhuo who was standing motionless and placed his eyes on various spiritual medicines on the ground.

He didn't even ask Liu Zhuo's name, but just pondered for a moment and said, "I'm going to start refining elixirs, don't make any sounds."

Seeing Zuo Ningshan's serious look, Liu Zhuo couldn't help but wonder, and nodded in a regular manner.

Then, Zuo Ningshan's eyes flashed. With a wave of his sleeves, a large amount of materials placed in front of Liu Zhuo were suddenly rolled up in the air.

Dozens of spiritual medicines were floating in the air, and then they rotated around Zuo Ningshan's tall body. According to a certain proportion, different spiritual medicines gathered together and divided into many portions.

Liu Zhuo stared at these spiritual medicines and began to secretly remember and speculate in his heart what the elixir of Gu Lingdan should be.

"rise!"

Zuo Ningshan whispered, and pinched several magic tricks in his hand as fast as lightning. The tip of his finger began to flash a dark red dazzling light.

As several magic tricks were completed, Zuo Ningshan raised his hand and waved his hand. A five-clawed red dragon formed by the fire three meters long condensed by fire emerged out of nowhere.

Next, Zuo Ningshan pointed his fingers and a little light appeared on his fingertips.

The fire dragon also circled around his body, and at the same time, various spiritual medicine balls floating around Zuo Ning Mountain were constantly being swallowed by the fire dragon.

When the Fire Dragon swallowed all the medicinal materials into his belly, waves of strange medicinal fragrance began to spread wildly in the entire pill room.

Liu Zhuo took a sip of air and felt refreshed. He could clearly feel that at this moment, the content of spiritual energy in the alchemy room had increased significantly.

After the fire dragon transformed from the fiery fire surrounded Zuo Ningshan for several consecutive circles, Zuo Ningshan pinched a magic trick and shot it into the fire dragon's body.

The next moment, amid the crackling and explosion of flames, the hot fire dragon roared silently. It opened its bloody mouth and countless golden spherical liquid was spit out.

"go!"

Zuo Ningshan pointed with his right hand, and the huge lid on the elixir furnace opened itself, and then the balls of golden liquid penetrated into it.

Bang!

The alchemy furnace was covered again, Zuo Ningshan's expression changed, and the glow in his hand flashed constantly. He pointed to the fire mouth under the alchemy furnace, and the five-clawed fire dragon above his head penetrated into the inside of the alchemy furnace with great momentum.

Suddenly, bursting flames began to burn on the top of the elixir furnace for no reason, making the medicinal smell in the elixir room even stronger.

Zuo Ningshan took a breath just now. With a wave of his sleeve, two spirit stones flew out of his sleeve bag, and fell into Liu Zhuo's hands.

"Every three hours, throw a spirit stone in, understand?" Zuo Ningshan pointed to the "leak" next to the alchemy furnace and said coldly.

Liu Zhuo looked at the two low-level fire spirit stones in his hand, nodded with a quiet expression and said, "I understand."

Zuo Ningshan didn't say anything. He glanced at the Dan Furnace, which was so strong that he sat back to the chess table, picked up the chess score and continued to study Go.

"This uncle is really fascinated by the way of Go." Liu Zhuo couldn't help but sigh in his heart. He put away the spirit stone and sat aside alone, but he was secretly recalling the recipe for Zuo Ningshan's refining Gu Lingdan just now.

With extraordinary memory, Liu Zhuo has kept the approximate types and amounts of medicines in mind, but he also knows the way of alchemy, and the requirements for the amount of medicines for each flavor are very accurate, so such a vague amount is naturally not possible.

If there is no accurate formula for Gu Ling Dan, you can only change the amount of the spiritual medicine and continue to experiment. If you have more experiments, you may happen to be successful."

Liu Zhuo couldn't help but secretly said: "Uncle Zuo's alchemy technique relies too much on his own cultivation. I may not be able to master it now. It seems that I have to find a replacement method."

Thinking of this, Liu Zhuo couldn't help but frown.

There are two problems before us:

First, it is the precise amount of various spiritual medicines when refining the Valley Spirit Pill.

The second is the technique of alchemy, and the alchemy furnace is also a big problem.

These are not problems that can be solved in a short while. Liu Zhuo secretly remembers them in his heart and can only find a solution in the future. Now he does not dare to meditate and practice, otherwise he will be in trouble if he misses the temperature of the pill.

So while watching the Dan Furnace, Liu Zhuo couldn't help but look at Zuo Ningshan who was studying chess scores.

Zuo Ningshan was holding the chess score in his left hand, and the middle finger and index finger of his right hand were intertwined, holding a white piece. He didn't look at the chess table with his eyes, so he landed on the chess, obviously comparing the chess book to play the score.

Although Liu Zhuo had never played Go, he also roughly knew how to play Go by reading some classics about chess by his predecessors.

While idle, Liu Zhuo focused on watching the movements on Zuo Ningshan chessboard.

After a little bit of observation, Liu Zhuo couldn't help but become very interested in the way of Go.

In the final analysis, Go is still a game of victory, the essence is: whoever covers a large area will win.

So it is not difficult to learn. Liu Zhuo just watched from the side. With his meticulous thinking, he could see some of the achievements. Zuo Ningshan was obviously an ancient book, and the subtle techniques in it were quite ancient.

Before we knew it, three hours had passed.

Liu Zhuo looked up at the "leakage" next to the alchemy furnace. Seeing that the time had arrived, and the fire in the alchemy furnace gradually weakened, he took out a spirit stone and carefully delivered it into the alchemy furnace.

As soon as the spirit stone entered the alchemy furnace, with a "boom", the flames in the furnace surged again. Through the gaps in the fire mouth, Liu Zhuo could even see the five-clawed fire dragon roaring inside.

Then, Liu Zhuo returned to a place not far from Zuoning Mountain and sat down cross-legged.
