This wait is over the New Year. In the first month, Liu Wu and his family made a sumptuous Chinese New Year's Eve dinner, cut some bamboo on the mountain and put it in the fire to burn it loudly, and the little girl jumped around the fire and high-fived, and the mountain had some taste of the New Year.

After the New Year's dinner, Ding Jiugu was driven back to the room by Gu Zuo to continue practicing, her time is Gu Zuo's time, absorb one more spirit stone, and the production capacity after the official start of alchemy will be increased by one more point in the future.

Half a month later, the masons and carpenters who returned home for the New Year returned to prepare for a month to put the finishing touches on it. In the meantime, I also have to cooperate with Gu Zuo to get a few pieces of furnishings.

The sound of ding dong knocking sounded again in the hall, the girl covered her ears and looked at it curiously, Sister-in-law Liu frowned and complained bitterly: "Why did you start digging again, such a good ground, polished!"

......

Throughout the first month, Gu Zuo didn't receive the news of Zhong Senjun's return, all he could do was to practice with Ding Jiugu while supervising the work. This was the month in which Gu Zuo spent the most spirit stones, twenty spirit stones, Ding Jiugu used twelve, and he used eight himself.

After entering February, the total number of spirit stones absorbed by Ding Jiugu reached twenty-four, which was equivalent to the true qi amount of twelve pieces of other monks, Gu Zuo entered her body again and probed once, feeling that it was almost equivalent to a monk in the early stage of qi refining who had practiced for half a year, so he stopped.

Can a Qi Refiner who has been practicing for half a year be able to refine the pill? Gu Zuo decided to give it a try.

Ding Jiugu is already her own apprentice, in any sect, this is her own person in law, Gu Zuo confessed the secret cave on the top of the mountain to her. After taking her into the cave, he took out a small Dan furnace: "This is the Dan furnace that the teacher specially went to the county town to buy for you, the magic weapon Dan furnace that can be used for alchemy, it is not a model product, it took eighty-six times to buy this Dan furnace for the teacher!"

Ding Jiugu was curiously looking around at the mine left by the Wangwu faction, and suddenly heard the number eighty-six, and was immediately shocked, and took it with trembling hands: "This is...... Mine?"

Gu Zuo encouraged: "Through the investigation of your cultivation in the past two months, I think you are better at alchemy, and you can develop in this area." ”

After that, he took out a copy of the "Dan Sutra", which was the "Miaosu Dan Sutra" that he had deleted from the text: "This is the secret method of this sect based on searching for spiritual true qi, and now I will teach it to you, so you have to figure it out with your heart." ”

Hearing that it was the secret method of the sect, Ding Jiugu immediately solemnly said: "The disciple must strictly abide by the secret of the sect!"

With the foundation of Sou Ling True Qi, you can learn everything quickly, because you don't need to start practicing from the exercises, you can get started directly. Gu Zuo carefully explained to her the key to alchemy and the problems that she might encounter in the process, and began to let her get started.

The essence preservation pill itself is not a difficult elixir, it only contains a kind of spirit grass of Yuanyang grass, which belongs to the lowest grade of the elixir, with the thickness of Ding Jiugu's true yuan, it should not be a problem to control the Dan furnace and condense the medicinal materials.

Ten medicinal herbs were put in, and a spirit stone was placed at the bottom of the furnace, Ding Jiugu's expression was slightly nervous, and she began to pinch the trick.

Gu Zuo watched her every move, every step, and every result the whole process, and reminded her to correct it from time to time.

A piece of spirit stone can refine three furnaces of essence preservation pills, in terms of time, a furnace of pills takes about two hours, as long as it is the refining method of searching for spiritual true qi to perform the Miao Su Dan Sutra, Yuan Ying is no different from a qi refiner when he comes, otherwise the heat is insufficient.

In the first hour, the refining process was quite smooth, although there were some stumbles, but the ten medicinal materials had been condensed, and the rest was a matter of heat, which needed to be continuously refined, fused the medicinal properties, and removed impurities.

After another half an hour, Gu Zuo carefully observed from the pores, and half of the ten pills began to glow with blue light. Gu Zuo's furnace of pills can produce nine or even ten pills, and he doesn't know how much Ding Jiugu can do. But as long as she can refine three grains, Gu Zuo will be able to keep her capital, and four grains will make money.

At this moment, beads of sweat the size of beans had appeared on Ding Jiugu's forehead, her face was flushed, and after a while, she finally couldn't help but gasp: "Teacher, I'...... I can't do it......"

Gu Zuo sighed in his heart, it seems that her true yuan thickness still can't support two hours of continuous alchemy, I'm afraid she will need to feed it for another two months to stabilize, and she is still in a hurry.

"I'll take over, you retreat slowly, I'll move in slowly, don't rush ......"

"Teacher, I really can't do it......"

"Bear with me a little longer, and you'll be fine in no time...... Hold on!"

The last three words are still shouting late, in fact, even if it is early, it is useless, the problem is that Gu Zuo entered late, or Ding Jiugu shouted late.

Ding Jiugu's true qi suddenly leaked, but Gu Zuo's true qi didn't have time to fill the gap, and the strong and weak changes of the two true qi were not well coordinated, which suddenly caused a turbulent flow of true qi.

The balance of the Dan furnace was broken, and it tilted to one side, and a white flame suddenly ignited inside, and then detonated the spirit stone on the base, and the entire furnace exploded in the direction of inclination, and with a loud bang, it hit the rock wall and exploded into pieces.

The Dan furnace is a magic weapon, and there is a spirit stone "pouring oil", the destructive power can be imagined, and a three-foot-deep crater was immediately blown up on the rock wall, and the fragments of the furnace and the medicinal materials in the furnace were scattered and splashed, Gu Zuo covered himself with a big sleeve in front of him, so that he and Ding Jiugu were not injured.

Gu Zuo was speechless, and turned his head to see Ding Jiugu's body trembling and her lips trembling, so he forcibly suppressed the regret in his heart and comforted: "Jiu Gu, don't be sad, it's not your fault, it's because the teacher is impatient, well, let's cultivate for another two months, this kind of problem can be avoided." ”

Gu Zuo walked over. Picking up the pieces from the hole that exploded in the rock wall, he couldn't help but sigh as he looked at the broken Dan furnace.

More than 80 treasures bought, just like that, reimbursed, it really hurts!

Ding Jiudan looked at the fragments of the Dan furnace that Gu Zuo took out, and suddenly burst into tears, not knowing what to say, just crying "I'm sorry" repeatedly. She is a person who has experienced hard times, and she has broken more than eighty things, which is almost like losing her life.

Gu Zuo was about to say something to resolve her guilt, but suddenly found that there was something wrong in the sea of qi, so he covered the rock wall with his palm, and the chasing technique was out.

With the feedback of the Photography Tracking Technique, there was something faintly in the stone pit that was blown out, and the spiritual power emitted flickered like a bright light in the sea of qi.

This is the result of the tracking technique perceiving the treasure, just like the five array flags he found back then.

This treasure was hidden behind the stone pit, Gu Zuo took out the Hengyi sword, and immediately excavated.

Ding Jiugu cried for a while, and saw Gu Zuo getting into the bombing pit, and from time to time there were gravel splashing out, and under curiosity, she stopped her sorrowful voice, and when she came to the pit, she saw Gu Zuo struggling to planing stones.

After digging more than three feet deep, Gu Zuo slowed down, and a little dark black gradually appeared on the rock wall, which was in stark contrast to the color of the ordinary stone wall.

After digging for more than half an hour, a black stone with a little fluorescence and the size of a bull's head appeared in front of the two of them, looking at it deeply, like a night sky shining with stars!

Gu Zuo was short of breath, this thing is a real treasure!

Hepthopthumite!
