Taixue enters the fifth grade, which is equivalent to entering the prelude to graduation, and most Taixue students arrange for the fifth grade students to start choosing the direction of their graduation thesis, and then spend two years researching, doing experiments and writing their thesis.

The choice of the topic for the dissertation is very important, and some students even spend half a year choosing it carefully.

Li Jingli is a college flower and a top student in the Natal Academy, but after entering the fifth grade, she is also very confused and entangled when choosing the topic of her graduation thesis. Although the subject of natal science, the school has only one rigid requirement for students to obtain a graduation certificate, that is, the student's own cultivation must break through to the Taoist realm.

Any student who can break through to the Taoist realm can get a graduation certificate, and the graduation thesis is only a supplement to cultivation, and the quality of the graduation thesis does not affect whether the student can graduate, because this discipline and the discipline of battle studies are the lowest requirements for graduation theses among all the immortal disciplines.

But Li Jingli is not an ordinary student, she has very high requirements for herself, and decided to draw a perfect end to her career in Taixue with a perfect graduation thesis two years later.

She began to go into the library to look through a large number of materials, collect all the materials that were useful to her, and thought that after collecting enough materials, she would sift through them one by one, and finally set the research direction of her graduation thesis.

For several days, she soaked in the library, and soon filled two notebooks, she put down the pen, looked at the second one she had written, and frowned, and found the information that was useful to her today and had not finished copying.

She stood up regretfully, and just wanted to get up to return the information, and wait for a new notebook to come back tomorrow to copy, when suddenly on the left side of the two empty seats, sat a fairly familiar figure.

Isn't this Liu Hai junior? Yo, yes, I started to soak in the library in the first grade.

Liu Hai glanced at Senior Sister Li in surprise, he didn't expect to meet her in the library, Bai Yu Taixue still has such a big one, but he didn't pay too much attention to it, handed over a few pieces of scratch paper, and lowered his head to write his experimental design.

There is one last point in the experimental design, and he can't wait to finish it quickly, and then go to the cafeteria to eat something casually, and go to the No. 1 laboratory building of Dan Pharmaceutical College to receive the experimental consumables.

Beauty or something, how can there be a refining elixir that is attractive.

Li Jingli stared at the bangs who kept writing with a brush, then pursed his lips and smiled, put down the manuscript paper, and began to study on his own.

Bangs was in the state, and in less than ten minutes he completed the last part of the experimental design, put down the pen and checked it from beginning to end, without any mistakes or omissions, and hurriedly picked up his things and walked out of the library.

Bai Yu Taixue's canteen is of good quality and low price, Liu Hai bought a few big buns made of lion leg meat on the principle of convenience, and hurried towards the No. 1 laboratory building while walking, and when he arrived, the medicinal materials from the logistics department had already arrived, and after receiving all the experimental consumables, Liu Hai came to the laboratory he applied for.

The moment he entered the laboratory, Liu Hai was really a little nervous, the laboratory is not big, but the instruments are complete, weighing tools, raw material processing instruments, medicine furnace combinations, and all three categories of experimental instruments are available, which can basically meet the refining of any one-turn elixir and the following drugs.

There are only medicinal properties testing instruments, unless it is a human drug test, it is a very complicated thing to use instruments to detect medicinal properties, especially the elixir-level medicinal properties testing, which requires a lot of super-large instruments, and small laboratories can't put it down at all, and these super-large instruments are very expensive, and they are tens of millions of gold coins at every turn, and the school cannot be equipped too much no matter how rich it is. Therefore, usually after the elixir is refined, it can only be taken to the medicinal property testing room equipped with the laboratory building for testing.

Liu Hai turned around in the laboratory, and did not rush to refine Bai Yuan Lingdan, first took out all the consumables and placed them on the disposal table, looked at them one by one, carefully checked the quality of all consumables, especially the medicinal materials, and finally had to sigh that Bai Yu Taixue is different, whether the logistics department is provided free of charge in the laboratory building or paid for the configuration of the logistics department, the quality is very good, and it meets the requirements on their list.

After the consumables were checked, the bangs began to familiarize themselves with the equipment.

This is an important step in the experiment, and familiarity with the equipment can often affect the success rate of your experiment.

It took Liu Hai two hours to get familiar with the experimental equipment, and at the end of the familiarization, Liu Hai went through the teaching materials of the Baiyun Lingelan refining in the inheritance bead in his mind, and read the experimental design he wrote according to the actual situation, and after being familiar with each experimental step, Liu Hai put down the experimental design and began to prepare for the formal treatment of medicinal materials.

Liu Hai applied for seven portions of medicinal materials, one of which was used for the first refining of the elixir, and the remaining seven were used as a comparative test for the optimization of the Ci Mo formula.

The preliminary treatment of medicinal materials generally has five elements, and each method has many subdivisions, which will often be organically combined with the other four methods.

Take the water method as an example, there are water invasion method, blister method, water flushing method, boiling method, water drying method, water milling method, water pressing method and so on.

It took Liu Hai two full days just to process the first medicinal materials for refining Bai Yuan Lingdan, and he didn't go anywhere halfway, except for squeezing time to go to the cafeteria to eat, he stayed in the laboratory to process and test the medicinal materials, and also made various experimental records.

All the raw materials were processed according to the prescription, and finally on the afternoon of the third day, a stock solution was formed, which was exported from one of the medicine furnaces, cooled for fifty minutes, and then imported into another medicine furnace for extraction.

The process of extraction was more laborious than before, Liu Hai prepared dry food, stayed in the laboratory for two days and two nights without going out, and finally began to enter the last step of the elixir refining on the night of the fifth day - forming the elixir.

Liu Hai looked at all the testing instruments, recorded the data in the book, and then sat next to the seventh medicine furnace used in this experiment, and began to meditate, all his energy was placed in the medicine furnace, using the true yuan of the dantian trick **, carefully perceiving every subtle change in the liquid medicine into the pill.

This kind of perception is also learning and academic accumulation.

This is one of the great effects of scholarship on spiritual practice.

The liquid medicine kept churning in the medicine furnace, and finally took shape into a pill in three hours, and at this one, an experiment that lasted for five days was initially over, and Liu Hai was already exhausted, Rao is he had the cultivation of the Taoist realm, and he was also tired from the consumption of five days.

But now is not the time to rest, he was not in a hurry to get out of the pill, the reality sat quietly for a quarter of an hour, summed up the perception of three hours, and then opened the medicine furnace, and a golden ball was placed in the middle, which was the result of Liu Hai's five days of hard work - a white yuan elixir.

Bangs turned to the elixir for the first time, and it was an unsurprising success.
