Chapter 6173

This situation made Tang Yu very disappointed.

Of course, he can't. now he wants to get in touch with how to use spirit sound stone to refine Shenyin yuan Dan!

So for Tang Yu, Lingyin stone is also very useful.

At this time, Tang Yu found that there were houses to rent in the city. He was stunned for half a day. He could not help but be speechless. When did such a powerful society develop like the earth, and even because of the demand, there was such a rental market.

Therefore, Tang Yuhua spent 80 Shen Yin yuan Dan, rented a set of three rooms and two halls, plus a single door courtyard of alchemy room.

Although the price of 80 Shenyin yuan Dan seems not expensive, in fact, by comparison, a good meal in a restaurant costs only two or three Shenyin yuan pills. You can understand that the price is actually very high.

But Tang Yu was very satisfied.

Because of this small yard, he can temporarily settle down in the city of making Dan and carry out his own plan!

Tang Tang was not satisfied with Tang Yu's idea of staying in the city for a period of time.

However, she also understood that it was not yet the day when the God's house of congenital Daoyin was opened. Even if she soon left Zhidan City, she could only wander on the mainland and do nothing.

It's better to let Tang Yu stay in the city of making Dan and study the printing and engraving skills. It's better to improve his strength by this way. After entering the God's mansion of congenital Daoyin, he has a greater chance of winning. He can find clues related to Xia Shihan and find out Xia Shihan.

At this thought, Tang Tang Tang was relieved and lived in this small yard with Tang Yu.

After Tang Yu came to the small yard, he did not manage Tangtang, but focused on how to extract Shenyin yuan Dan from Lingyin stone!

After reading the pamphlet, Tang Yu felt that he had been trapped by others, because the seemingly thick one actually contained less than 10 sentences, and the total number of words was no more than 100 words.

A hundred words, what can you introduce? Even if introduced, it must be bullshit!

In this way, the pamphlet is also sold for eight Shenyin Yuandan, which is equivalent to one tenth of the cost of renting a house for a month.

Tang Yu understood why his boss didn't let him read it at that time. It seems that the boss knew that the contents of this pamphlet were a trap.

And he also told him that he would not return the goods, probably to stop Tang Yu's mouth!

But Tang Yu only wanted to know how to use Lingyin stone to refine Shenyin Yuandan. He didn't notice the seller's reaction at all. Otherwise, he would have found something wrong.

This also made Tang Yu regret.

But later Tang Yu thought that there was such a thing, and clearly indicated that it was the method of refining Shenyin Yuandan with Lingyin stone. There must be his reason, so Tang Yu studied it seriously.

This reading really made Tang Yu discover some situations.

Tang Yu understood something vaguely. Of course, this was only a combination of his own conjecture and got a method to refine Shenyin Yuandan with Lingyin stone.

As for the result, Tang Yu is not very clear, so he began to try.

Tang Yu didn't expect that the first time he refined it, he would be able to refine shenyinyuan Dan with only a small amount of Lingyin stone.

In fact, just like Tang Yu's own conclusion, he refined it according to his own conjecture. He was depressed to find that he could only extract one Shenyin Yuandan from ten Lingyin stones.

That is to say, this ratio is exactly the proportion found by the engravers of Dancheng in their practice.

Such a result naturally made Tang Yu very dissatisfied.

He has a very high talent for engraving and alchemy. Since refining Shenyin Yuandan with spirit sound stone is a kind of thing for the engraver to practice, it will be easy for him, who has a strong talent.

Therefore, Tang Yu refined it again, but this time, he was very attentive. He tried his best to find out some of the changes.

At last, Tang Yu really found the key point of the transformation of Lingyin stone into Shenyin Yuandan.

In fact, refining Shenyin Yuandan with Lingyin stone is actually only to remove the impurities in the Lingyin stone, and then compress the remaining part to the extreme, which becomes Shenyin Yuandan.

Just at the beginning, Tang Yu didn't know this, so he didn't find anything.

At that time, they thought that Shenyin Yuandan was actually extracted from Lingyin stone and compressed into Shenyin Yuandan.

Therefore, at the beginning, it took a lot of spiritual sound stone to make a divine Yin yuan pill.

Later, they gradually realized that they didn't need to use a certain spiritual sound stone as the noumenon, and then removed impurities, and then compressed the extracted things from other spiritual sound stones into this noumenon spiritual sound stone.Therefore, there is only a few spirit sound stone, can extract a god Yin yuan Dan.

This is because, when removing impurities, they can not completely eliminate impurities, at the same time, there will be some things they need to be removed.

In fact, in essence, a spiritual sound stone can extract a divine Yin yuan pill. As long as impurities are removed, the useful things are not wasted.

After discovering this situation, Tang Yu was greatly surprised.

To remove impurities, we use the mind. For others, the mind may not be enough. However, in the land of Shenyin, no one can compare with Tang Yu's, so it is impossible for others to extract Shenyin Yuandan from Lingyin stone. As long as Tang Yu works hard, he can definitely do it.

So, the overjoyed Tang Yu started the experiment.

In the process of the experiment, Tang Yu realized that it was very difficult to eliminate impurities completely without wasting musical materials.

After countless attempts, Tang Yu consumed almost 50000 spiritual sound stones, and finally achieved the level of refining a divine Yin yuan Dan with only one spirit sound stone.

Although the process was more painful, Tang Yu also got nearly 8000 Shenyin yuan pills.

The extra 3000 pieces, of course, were due to Tang Yu's later proficiency.

Tang Yu spent three days on the experiment.

It made him very dissatisfied.

However, if others knew that Tang Yu only took three days to refine it in a single time. He could extract a divine Yin yuan Dan from a spirit sound stone. I'm afraid he would envy, envy and hate to death!

Especially for those cattle who make profit by price difference, as well as the engravers, it is estimated that they will directly crash into the tens of thousands of meters high wall and suffocate to death!

Once he had done this, he could use a spirit sound stone to refine a Shenyin yuan Dan. Naturally, Tang Yu wanted to do it, and he could extract a lot of Shenyin yuan pills at one time.

He didn't forget that the little guy in the exchange told himself that he had already done mass refining.

Therefore, Tang Yu is equivalent to starting from scratch.

However, this time, I have already had experience, and it is just to turn a single time into a batch. To Tang Yu, it should be a relatively simple thing.

Even if it was simple, Tang Yu spent a day and 10000 spiritual sound stones to achieve this.

"Hooray! Finally it's done! " Tang Yu was very satisfied. He walked out of the alchemy room and came to the courtyard. He breathed the fresh air, as if to vent his anger. In the alchemy room, these people held back their grievances again and again.
