After tidying up the insect room a little, song Qingyun took care of the remaining ten bottles of insect food. Gu Zhun went to the medicine garden.

    Gu Zhun was very interested in the medicine garden in the cave. When it was opened up, Gu Zhun specially arranged a gathering array here to make the land gather aura and become more fertile.

    The medicine garden is not big, but it is not small. There is a whole ten Mu medicine field. At the moment, different kinds of medicinal materials are planted neatly.

    At the moment, it is only more than a month away from the planting of medicinal materials. Even with the help of Juling array, Gu Zhun''s growth is not particularly gratifying. Gu Zhun stands by the ridge and looks at these newly emerging medicinal materials with a slight frown.

    After a while, he squatted down directly and dug up the soil with his hand under the puzzled gaze of song Qingyun.

    Layer after layer of soil was dug out by Gu Zhun and received the storage ring. Song Qingyun, standing beside Gu Zhun, was completely stunned.

    She didn''t know what was wrong with her childe. She looked at the medicine garden well and squatted down to dig the ground.

    Also, why dig so much soil into the storage ring?

    It''s not a baby.

    Song Qingyun doesn''t understand, or any other person can''t understand what Gu Zhun''s strange move is about at the moment.

    However, Gu Zhun didn''t explain anything about his behavior. After digging the soil full of storage rings, he turned and walked to his stone chamber without saying a word.

    Back in the stone chamber, Gu Zhun opened the furnace directly and poured the soil in the storage ring into the medicine refining furnace.

    Such a move stunned song Qingyun. If it wasn''t Gu Zhun himself, I''m afraid song Qingyun thought this man was stupid.

    Isn''t it nonsense to pour the earth dug out of the ground into the medicine refining furnace?

    Can this clay be used to refine medicine?

    Song Qingyun was puzzled.

    However, song Qingyun didn''t say anything, because she had absolute confidence in Gu Zhun. She never took an ordinary road, and maybe she had some ideas.

    Of course, soil can''t be used as medicine to refine pills. This is the rule of heaven and earth. Even if Gu Zhun''s medicine is powerful, it can''t be changed.

    He threw the excavated earth into the medicine refining furnace for refining spirit, in other words, refining earth.

    This is a secret method of promoting the spirit of the earth among the nine kingdoms in ancient times, which is called the secret of the ancient medicine kingdom. Later, it was lost with the collapse of the ancient medicine kingdom.

    According to the records in the ancient kingdom of medicine, this method of refining spirit can be refined seven times at most.

    Each refining will enhance the spirituality contained in the soil.

    The holy land after one refining will be equivalent to a time accelerator.

    The speed of time will be ten times faster when ordinary medicinal materials are planted. That is to say, if a medicinal material is planted on the spiritual soil of one-time refining, it only takes one year to grow the medicinal age. The medicinal power contained in this medicinal material is comparable to that of ten-year spiritual medicine.

    Mysterious.

    If it is the spiritual earth for twice, the time flow rate will be increased ten times.

    By analogy, if you can refine a piece of spiritual soil for seven times, if you plant a medicinal material on such spiritual soil, it will mature immediately and reach the medicinal power of a century old medicinal material after only one day of planting.

    Such an increase is simply appalling. Perhaps it is such a kind of alchemy, so in ancient times, this is one of the reasons why the ancient country of ten thousand drugs collapsed.

    After putting the clay into the medicine stove, Gu Zhun selected some other precious medicinal materials according to the special method of refining spiritual earth in his mind, and then began to urge the spiritual power to start refining.

    A burst of crackling elixir and the sound of soil refining sounded. After half a cup of tea, the first refining was completed.

    When you open the Dan stove, you can see that a layer of white treasure light shines out of the medicine stove, which is very eye-catching.

    Moreover, a refreshing fragrance was also passed along. Needless to say, this refining was successful, and more than that, even the earthy smell in the soil was completely removed, which was like a rebirth.

    Looking at the new soil in the medicine stove and the powerful spirituality that came to her face also made song Qingyun''s mood restless for a long time.

    Although she doesn''t know how to refine medicine, just looking at the refining techniques of her childe, she can vaguely feel that her master''s medicine level has reached a peak.

    Even the earth can be refined into this, which is simply refreshing her world outlook.

    However, Gu Zhun was obviously not satisfied with the spiritual land that was only refined once.

    Glancing at the herbs around him, Gu Zhun was still very sufficient at present, so without hesitation, he closed the furnace again and began his second soul refining.

    Compared with the first time, the second alchemy must use more herbs, and the time has doubled.

    At the second opening of the furnace, the spiritual earth in the medicine refining furnace changed from white to green, and the number of spiritual earth decreased.

    In this way, Gu Zhun refined this furnace of spiritual soil five times in a row. If there were not enough herbs around him, Gu Zhun would directly refine these spiritual soil to the top seven times.

    However, due to the limitation of medicinal materials, the color of spiritual earth can only be fixed on a sky blue color.

    When such spiritual soil is taken out of the medicine stove, the great spirit can be said to be no less than any kind of pill.

    So this is why planting herbs on such spiritual soil will get twice the result with half the effort.

    Seeing Gu Zhun pour out the spiritual soil, song Qingyun is not idle, just to help transport the spiritual soil that has been refined five times to the medicine garden of the cave.

    In the next two days, Gu Zhun, song Qingyun and the black water black snake were completely immersed in the medicine garden for the big project of soil replacement.

    Two days later, as the soil in the medicine garden was completely renewed, the herbs became more energetic as if they had lived again. Gu Zhun was finally satisfied.

    After finishing this, Gu Zhun also suddenly felt that his body seemed to have changed, so he didn''t have time to explain anything to song Qingyun, but went back to the stone chamber of the cave alone.

    On the stone bed, Gu Zhun sat cross legged and looked inside at the Dantian. As expected, after swallowing Huang Zhong''s five hundred Qi tripods a few months ago, his blood tripod in the Dantian finally had some unique changes.

    After thoroughly digesting the five hundred Qi tripods, another brand-new blood tripod was split out of Gu Zhun''s Dantian, and the two blood tripods were arranged in Gu Zhun''s Dantian, one left and one right.

    Suddenly, he felt his strength soared several times at this time.

    Moreover, his golden winged Dapeng Jue seems to have made great progress with the change of his blood tripod, and is completely moving from the black skin stage to the silver skin in the second stage.
