In the cave of the sea of clouds in the lonely mountain, Wu Yan sat on the stone bench, looking at the small stove on the stone table in front of him with a strange face.

The small stove has now reverted to an ordinary appearance, except for the smooth and delicate outer wall and the simple and elegant shape, even the faint dark green light has disappeared. Ten moirés and two strange and intricate symbols, there is nothing unusual about it.

For a whole night, the intricate symbol on the outer wall of the small stove adsorbed a little green soil about the size of a grain of rice, but the inside of the stove had a drop of transparent liquid the size of a soybean.

The function of the mysterious green soil, Wu Yan has discovered one point, that is, buried under the herbs, it can quickly ripen the herbs, and even the ordinary herbs can be spawned into hundreds or even thousands of years of elixir, of course, the premise is that Wu Yan is willing to use more green soil to ripen the herbs. But how did this new transparent liquid that appeared in the furnace come to be and what is the use, Wu Yan was a little confused.

Could it be that the ten clouds of clouds absorb the moonlight to form this drop of liquid, and what is the use of this liquid?

Wu Yan Muran's face suddenly moved, and he decided to conduct a thorough test of this small furnace and green soil, as well as this newly appeared transparent liquid. He was bound to discover the secret of this little furnace thoroughly.

Do what you think. Wu Yan is not a person who drags mud and water. After careful consideration, he first continued to choose a suitable place in the Thousand Grass Valley, and continued to collect green soil and transparent liquid with a small stove.

After repeated attempts and observations during this period of time, Wu Yan has discovered some characteristics of green soil. The mysterious green soil cannot be stored directly in a small cloth bag or an ordinary container. At first, he collected the green soil in a small cloth bag, and he accidentally found that the aura in the green soil was lost unconsciously, and basically if it was not treated, the aura on the green soil would be completely lost in about five days and turn into ordinary plaster.

However, if the green earth continues to stay on the small stove, the aura will not be lost. Later, through continuous comparison and experimentation, if you use a bronze container to contain green earth, the aura of green soil will be preserved for a long time, and the rate of loss of aura is very slow. Therefore, the green soil he now collects is contained in a delicate small bronze box. This delicate bronze box was given to him by Zhang Tao's father, Zhang Blacksmith. When he went to Gushan Town to customize the bronze box, as soon as Zhang Blacksmith heard that he knew Zhang Tao and was the same door as Zhang Tao, he refused to accept his money for anything. This made Wu Yan appreciate the honesty and kindness of Zhang Tao's father and son.

In view of the honest and honest character of Zhang Blacksmith's father and son, Wu Yan also made a decision in private, waiting for an opportunity to give Zhang Tao a few Qi Gathering Pills that he personally prepared.

After figuring out the properties of green soil, the first thing to do now is to test the properties of the newly obtained clear liquid.

After a few days of observation and experimentation, he was depressed to find that the newly obtained transparent liquid was even more speechless than the green earth. The transparent liquid was indeed formed by the ten clouds of moire through guò absorbing the moonlight. Moreover, this transparent liquid also seems to be full of aura. However, clear liquids are more difficult to preserve than green soil.

As soon as it leaves the small stove, the transparent liquid begins to evaporate. If you can't find the right way to store it, within an hour, the transparent liquid will completely volatilize, especially during the daytime, the volatilization is faster, almost at a speed visible to the naked eye, turning into white gases and dissipating in the air. It's a little better at night, and the evaporation is much slower.

Through continuous experiments and comparisons, Wu Yan has used various metal vessels, small porcelain bottles, small gourds and other various containers to hold transparent liquids, and he found that these containers can not effectively preserve this transparent liquid, only when it is contained in jade containers, this transparent liquid can be preserved for a longer time, and the better the quality of jade, the longer the storage time.

After more than ten days of trial and error, he finally found a container that could temporarily store the transparent liquid, and Wu Yan breathed a sigh of relief and began to test the function of this transparent liquid again.

Wu Yan thought that since the green soil could ripen herbs, this transparent liquid was also obtained from a small furnace, did it also have this function?

So he selected a few herbs as experimental samples and transplanted them into the southwest corner of the Yunhaidong medicine field. He first dropped a drop of liquid on top of a selected herb with a small jade bottle, then put away the jade bottle and squatted next to the herb to observe the changes in the herb.

To his disappointment, after a few days of observation, he found that the herb did not seem to increase the appearance of the year at all, except that it had become more verdant and full of medicinal energy.

Still not giving up, Wu Yan chose another hydrangea for experimentation. As a result, to his surprise, this hydrangea also did not increase the appearance of the year at all, except for becoming more medicative.

Wu Yan was a little depressed. Could it be that this clear liquid, like the morning dewdrops, although beautiful, has no other use?

However, after more than ten days of repeated observation and comparison, Wu Yan still found something special.

He found that the herbs that had been dripped with a clear liquid were much more apotently augmented than those that had not been dropped, which showed that the clear liquid must have a special purpose, but he had not yet discovered what the biggest use of this transparent liquid was. Moreover, after careful observation, he also found that the herbs that had dripped through the liquid seemed to have some black-gray impurities expelled from the leaves and rhizomes of the herbs.

This discovery made Wu Yan feel a little gratified. From this point of view, it shows that this transparent liquid is still useful, at least it has the medicinal qi to purify the herbs, discharge the impurities of the herbs, and make the herbs more spiritual.

Moreover, he also found that if the herbs that had been dripped with transparent liquid were ripened with green soil, the herbs obtained were no longer ordinary herbs, but legendary elixirs. The Ziyang Pill prepared with this elixir, after taking it, was actually very beneficial to his cultivation at the seventh layer of the current Qi Refining Period.

During this time, in addition to testing the use of green soil and transparent liquid, Wu Yan's cultivation did not delay. He had prepared Ziyang Dan again. It's just that since his cultivation of the "True Technique of Qi Cultivation" reached the seventh layer, the effect of Ziyang Pill on his cultivation has become minimal, even if he uses the Ziyang Pill prepared with the hydrangea that has reached a hundred years of ripening, the effect is still very limited. This is also a point that makes him quite distressed.

However, now the effect of using this Ziyang Pill prepared with this dripping transparent liquid Hydrangea has returned to the feeling of rapid improvement when I took Ziyang Pill on the fourth layer.

Wu Yan, who was still a little unrelenting, continued to test this transparent liquid. After all, the process of obtaining this transparent liquid looks very mysterious and powerful, so he doesn't believe that transparent liquid is only used for this purpose.

After trying the herbs, Wu Yan changed a few poisonous herbs for experimentation.

This experiment surprised Wu Yan. Even, without any psychological preparation, Wu Yan almost lost his life because of these poisonous weeds. So much so that in future experiments, Wu Yan had to take some Qingling Powder every time, and then put a special mask on his mouth before he dared to continue the experiment on poisonous weeds.

This transparent liquid dripped on the poisonous weeds, which actually made those poisonous weeds, which were already very poisonous, several times more violent, and seemed to have a spiritual appearance. This made Wu Yan very surprised and depressed.

This transparent liquid dripped on the herbs that were very useful to him, as if there was not much change, how could it be dripped on the poisonous weeds, but the effect was so obvious? Could it be a poisonous spiritual liquid?

In order to understand the doubts in Xingxing, and to verify an idea that had popped up when he first got this transparent spiritual liquid, Wu Yan decided to use animals to try this transparent spiritual liquid.

When he first got this kind of transparent spiritual liquid, he had a bold guess, could this spiritual liquid be taken directly? After all, the transparent spiritual liquid gave people the feeling of full of aura, and it looked very good, and even seemed to be very delicious.

Thinking of this, Wu Yan bought four black cats from Gushan Town for experiments.

He had seen a rumor in many texts that black cats generally had nine lives, and seemed to have an innate super-acute perception of poisons and ghosts. He felt that it was only fitting to use a black cat for this experiment.
