After the banquet was dismissed, the five of them cleaned up the dining table and kitchen together, Xi Mo and Lu Xiaoman made an appointment to send her to class tomorrow, and they and Le Lun drove He Feng and Chu Rui away respectively.

Lu Xiaoman washed her hands, entered the chemistry laboratory, and began to do chemical experiments on the discarded spirit stone, she has been busy with the study of the spell side, and she has no knowledge of the physical and chemical properties of the discarded spirit stone.

The waste spirit stone left by the mining of the spirit vein is a resource waste that has no value even for making spirit beads, the texture is hard, and it can not be reused, so it can only be thrown on the spot on the waste rock field next to the mine.

These discarded spirit stones, which are regarded as garbage, are free experimental materials, Ye Zhou has his own hands and methods to break these stones into small stone particles of uniform size, Lu Xiaoman spread out a beaker on the table, put one in each beaker, pour different concentrations of acid and alkali solution in turn, and let it stand at the current room temperature to see if there is any reaction after a period of time.

Then, putting aside the observation experiment to be waited for here, Lu Xiaoman took another set of tools out of the empty beads, found an idle empty room and set them one by one, and began to prepare for the air composition experiment.

How Lavoisier determined the composition of the air back then, Lu Xiaoman copied the experience of his predecessors, but the material used for the experiment was not mercury, but another kind of easy-to-heat refining metal spiritual material, because the reference material said that all spiritual materials can be used, but the monk used spiritual materials to do experiments relatively quickly, and he was not afraid of wasting materials due to improper fire temperature control.

Ye Zhou Fengyuan and Xiao Heilong gathered around the door to watch, when Lu Xiaoman was about to start heating the utensils, Ye Zhou flicked his fingers, and flew out a trace of Dan Fire to envelop the utensils, his fire temperature was high, the metal took half an hour according to the general melting speed, Ye Zhou's Dan Huo only used half a stick of incense to burn the metal into an off-white powder, looking like dust.

The next experimental step is to follow step by step, first calculate the oxygen, after the verification is completed, the remaining mixed gas is pressurized and liquefied to continue the separation experiment, and finally a bottle of mixed gas containing aura is obtained, according to the reference data, the proportion of aura in the air composition is not high, even the aura content in the first-class empty bead is only about the same as the proportion of carbon dioxide under normal conditions, so Ye Zhou's people think that aura can be classified as a rare gas, and when the monk is cultivating, the skin meridians of the body will only absorb aura, If you use air as a raw material to prepare Reiki, you can separate it to this step, and you don't have to force a pure and impurity-free Reiki, although it can be done, but it will cause a large increase in cost.

However, Reiki is a colorless, odorless, and water-soluble gas, and it is precisely because it is soluble in water that there is a water body rich in Reiki such as Lingquan Linghu, and because the solubility is not large, excess Reiki will overflow into the air.

In the same way, once the sealed container of the aura is opened, the aura inside will immediately merge with the air, so how to use the aura is a difficult problem, and the reference materials do not have this answer, obviously Lu Xiaoman has to figure it out by himself.

Lu Xiaoman solemnly labeled the bottle, sealed the mouth of the bottle, and carefully held it in his hand to look at it, his eyes as if he was looking at his beloved lover.
