When Zhang Yixing and Zhuo Yuan reappeared in Taiping City, it was a month later.

At this time, the four of them had moved to the courtyard halfway up the mountain in Taiping City, and everything was available in this courtyard: an alchemy room with earth fire, a refining room, and a trial hall, and a spring behind the courtyard was flowing in tinkling dong, revealing the builder's ingenious idea everywhere, which made people happy.

That Lu Fang was the family manager of this courtyard, and seeing that the four of them could live in this courtyard of three thousand spirit stones for one month in just a few months, he admired the ability of the four of them to make money.

You must know that the cost of monks in the foundation building period is not small, if you want to expand the meridians, spirit stones and pills are indispensable, and you have to practice the Yuan Shen from time to time, and the cultivation of the Shen Pill is also essential, so that the cost of a thousand spirit stones a month is not small, this is not the rent, but look at the people-

The courtyard of these five hundred spirit stones is not easy to live in, and I have to go up to the next floor, and I have to live in the three thousand spirit stones for a month, let me calculate, how many spirit stones will be spent this month, this rent is four seven two thousand eight per month, four five two hundred, and the monthly rent per person is seven hundred and five, and the spirit stones used for cultivation -

I've seen the medicine stickers they make in the market, and I haven't seen much business, so it's so profitable? Isn't it that I'm usually used to being idle, a little lonely, no, I have to buy two stickers to try when I'm free, hey...... I'm not looking for a doctor, forget it, as long as I serve several people, it's the right way to get some extra money.

Thinking of this, Lu Fang pinched the small bottle of Turbidity Pill given by Su Xiaolan in the storage bag, and went satisfied.

At this time, Zhang Yixing was standing with Zhuo Yuan in the refining room, the room was very dry because of the earth fire, Zhang Yixing looked at the earth fire and asked Zhuo Yuan: "Is this earth fire good?"

Zhuo Yuan nodded, so the two of them took out fine iron, as well as some large and small boxes.

It turned out that in the crack in the ground, the two found the earth fire generated by the flow of magma underground, Zhuo Yuan made a few boxes with the mysterious stone, and the two of them didn't know what to call the stone, because it seemed to have no weight, so the two gave the stone a name: light stone.

With the help of Zhang and his entourage, Zhuo Yuan smelted the magnet into four square magnets, and put them into the light stone box before the two of them breathed a sigh of relief, and then under the guidance of Zhuo Yuan, the refined iron was roughened again, because there are a lot of refined iron, and it will take more than two months to refine all of them into refined iron.

Now the first priority is to refine enough refined iron first, Zhang and his entourage will first rough the refined iron again, and then Zhuoyuan will refine the finished product.

Then the two of them worked in full swing for more than ten days, during which the Su sisters would also come to serve tea and water if they didn't go to Fang City, and the four of them worked together to finally refine the refined iron used.

At this time, Zhang Yixing said to the three people:

"What should this instrument I want to make be called? I think it's called the spirit pressing machine first, and the function is to crush the lower grade spirit stone and then re-press the spiritual energy into a medium-grade spirit stone."

"I have tested the difference between a low-grade spirit stone and a medium-grade spirit stone, the total amount of spiritual energy of these hundred lower-grade spirit stones is about twenty percent more than the amount of spiritual energy of a medium-grade spirit stone, despite this, it is much more difficult to practice with a lower-grade spirit stone than a medium-grade spirit stone. ”

Zhang and his entourage looked at the three of them and continued:

"You also often use the lower grade spirit stone to practice, and you also know that this lower grade spirit stone not only has to take the Turbidity Pill to clean up impurities, but also use exercises to avoid impurities from causing harm to the body. ”

"And I have also tried the medium-grade spirit stone, and it does not cause much damage to the body, and as long as you usually practice, you can clean up this kind of damage. ”

"If we succeed in making this kind of instrument, the market will definitely not be a problem, and then the spirit stone will roll in, but I am afraid that at that time we will have to worry about how to hide from the world, and not let people find out that the medium-grade spirit stone is pressed out by us with the low-grade spirit stone. ”

"Of course, it's too early to say this, so let's figure it out after we do it. ”

The three of them were a little shocked after hearing this, this matter has a strange idea, under normal circumstances, the medium-grade spirit stones used by the monks are produced from the mine, no one wants to use the low-grade spirit stones to make the medium-grade spirit stones, if this is successful, it is tantamount to an inexhaustible spirit stone vein, no wonder Zhang and his party are very mysterious, the three of them feel that this matter must be carried out very secretly, and they can't reveal the slightest rumor.

Next, Zhang and Zhuo Yuan discussed the design plan, Zhuo Yuan thought of the special surname of the magnet, as soon as there was a magnet, he had to use a light stone to control the magnet, after repeated simulations, the plan was finally finalized, and the two began a new round of work.

After ten days of busyness, six large iron plates two inches thick, as well as two small narrow plates, and a small iron block and a few connecting rods appeared in front of the two of them, and the two did not rest, and soon began to assemble, and soon a six-sided all-iron box was assembled.

Soon the two moved the box to another unused room, as far away from the fire as possible, and then began to experiment, and the Su sisters also returned from the Fang City, and also walked into the room to watch.

"Close", "Release Spirit Stone", "Close", "Grind Spirit Stone", "Pull Space", "Press-"

"Open-" With the voice of Zhang and his entourage, a spirit stone appeared in front of the four of them, Su Xiaoyun took this spirit stone in his hand in surprise, the purple spirit stone looked as translucent as a water droplet, which made Su Xiaoyun not only a little intoxicated.

Zhang and his entourage took out a medium-grade spirit stone and handed it to Su Xiaoyun for her to compare.

Su Xiaoyun watched it for a long time, and still felt that it was better to make it just now, Zhang and his entourage asked her to use two kinds of spirit stones to test it first, Su Xiaoyun meditated and absorbed the spirit stones, and after a while, he got up and said that the spirit stones that were pressed out were pure.

Zhang Yixing and Zhuo Yuan then pressed five or six spirit stones for the Su sisters to comment.

Soon, the Su sisters lined up the seats for these spirit stones. Zhang Yixing looked at the opening and said:

"I used eighty-five pieces of the spirit stone I pressed first, and the spirit stones pressed below are all decreasing by one in turn, and it is more appropriate for the three Daoists to see which one we should use. ”

After the last few people discussed, they decided to use the eighty-three low-grade spirit stones to press the middle-grade spirit stones, so that it would not make people suspicious because it was too good, and it would not affect the business because the aura was too little.

As for the method of buying and selling, the Su sisters have already thought of a way to hide people's eyes, that is, when someone buys a medicine patch, it can be exchanged, only that it is a preferential measure, but there are also quantitative restrictions, if it is too large, it will be delivered in batches, and this person will not go around publicizing it if he gets cheap.

In this way, although there are a lot of people who trade, if they can keep it secret, they just think that it is just for their old customers, and if someone occasionally asks, it can also be inferred that there are customers who use medium-grade spirit stones to trade medicine patches. In this way, no one would have imagined that this high-grade spirit stone was actually made by ourselves.

Of course, the exchange ratio is still 100 to 1, which is generally the same as the outside world.

Hearing this, Zhang Yixing said: "This approach is relatively safe, but safety has become a problem, after all, sometimes tens of thousands of spirit stones are traded, and there are mixed fish and dragons in that market, and it is not good to be targeted." I think it's better to rent a storefront, and now we don't have to worry about the problem of spirit stones, I think it's okay to hire a few more people to look at the storefront, so that we can also have time for our own cultivation. ”

Zhuo Yuan hurriedly said, "It's no problem to find someone, I can ask my junior sister and junior brother to come over to help." ”

Su Xiaoyun's eyes glared and said: "As long as you have a junior sister and junior brother, we can find dozens of people in Tianxiang Valley with a casual stroke, and leave the matter of finding people to me, I will take people now." As she spoke, she was about to get up, and Su Xiaolan hurriedly pulled her down.

Su Xiaolan opened her mouth and asked: "Big brother will see how many people there are, and then Brother Zhuo will bring people first, if there is still a place, let Tianxiang Valley also have a junior sister, Brother Zhuo thinks this is okay?"

Zhang Yixing said: "You have to look at the store, you have to have two, you have to have two pharmaceutical stickers, and Brother Zhuo has to have one, if you can have a mobile person, so that they also have a time to practice, so that there will be six people, and nothing else will be needed - this spiritual pressure machine is only known to the four of us, and it is only limited to the four of us." ”

"As for the remuneration, I think it will refer to the Chen Lu family, but we have to pay a higher price than them, and this spirit pill and Pei Shen Dan must also be supplied on time, what do you think?"

The three of them just wanted to bring their relatives and friends, and they didn't plan to ask for any spirit stones, not to mention that this medicine patch and spiritual pressure machine were all led by Zhang and his party, and they could be divided into them, but they didn't expect relatives and friends to receive favors when they came, and they didn't know how to thank Zhang and his party.

After a pause, Zhuo Yuan said: "Then I'll bring my junior sister over, after my master immortal went, my junior sister was lonely, and my senior brother didn't take good care of her, so let her come or watch the store, or make stickers, although the other junior brothers are not rich, but there are some relatives to rely on, let Tianxiang Valley come to the rest." ”

Su Xiaolan still had to persuade Zhuo Yuan to bring two more over, so Zhuo Yuan said: "Good men are ambitious in all directions, if they can't even break into this Taiping City, then it doesn't make a difference whether I help them or not." ”

Su Xiaoyun glanced at Zhuo Yuan with a smile on his face when he heard this, Zhuo Yuan's face turned slightly red, and his heart blossomed.

After deciding, the four of them pressed you and me one by one for an hour, and there were five hundred medium-grade spirit stones out of it, this is because the box borrows the power of the magnet, the design is reasonable and simple, and it is very convenient for people to make it, and the four of them are a little happy to do it, Zhang Yixing retreated at a glance, pulled Zhuo Yuan and said:

"Brother Zhuo, I have an idea, I want to refine my flying sword again, Brother Zhuo, let's listen to me first, is it feasible?" and then explained the thoughts in his heart to Zhuo Yuan.

Zhuo Yuan heard it and said: "Brother Zhang's idea should be feasible, I also talked about the Zimu Sword when I heard the refiner preach, but Brother Zhang's idea is even better, we also have this superb magnet now, so let's try it." With that, he walked towards the refining room.

When the next day dawn the two came out of the refining room, Zhang Yixing held the flying sword that had been re-refined in his hand, only to see that the tip of the flying sword was attached to a small sword body with two sharp ends, Zhang Yixing's spiritual power on the flying sword, the small sword body with two sharp points turned on the big sword body, dizzying, the flying sword waved up, the small sword body shot straight into the sky with a 'whoosh', and Zhang Yixing put the sword back in his hand again, and the small sword body flew back with a 'whoosh', leaning on the big sword body and turning around.

Zhang Yixing was overjoyed, stroked the sword body and said, "From now on, I will call you 'Clutch Sword'."
