The two ingredients are started together, a crucible for silver leaf grass and a crucible for Ningshenhua, and different medicinal herbs cannot be mixed together at first.

It took him ten minutes to heat the two crucibles, and although he could raise the temperature of the furnace and melt faster, it was difficult for the melt of the material to meet the requirements.

The boiled Silver Leaf Grass is pale silver, and the Tranquility Flower is pale green, as if it had nothing to do with the red color of the secondary life potion.

Grab the handle of the crucible and remove the crucible from the furnace, put it on a wooden board, then take two evaporation dishes, use a strainer to filter out the slag, and the remaining light silver liquid and light green liquid leak into the two evaporation dishes respectively, and then put them on the heating stove to heat.

The evaporation dish is a test tool for concentrating materials, and when heated evenly on the furnace, the excess water will be evaporated, leaving only the concentrated material.

When the melt in the evaporation dish is evaporated because of the excess water, and slowly changes from light silver to silver, after reaching a certain level, Ye Qing turns off the furnace and uses a tongs to pick up the evaporation dish and put it aside to cool it slightly.

The two parts of the melt are put aside to cool to a certain temperature, and the specific temperature is not stated in the formula of the elixir, only that it is certain, and there are some cheats.

This is the limitation of the times in the dungeon, there is no thermometer, it is all based on empirical estimates, which is the main reason why it is so difficult to become a pharmacist, it is too cheating.

Ye Qing had no choice, so he could only estimate it empirically, first try a time when it was about fifty degrees, pick up the evaporation dish and pour the liquid inside into a flat-bottomed beaker, and then gently stir it with a glass to make the silver melt inside more uniform.

Setting this beaker aside, he immediately poured the tranquilizing flower melt from the evaporation dish on the other side into another flat-bottomed beaker and stirred the green melt well.

This step is very important, the agitation should be even, not too slow and not too fast, slow and even.

These are the first steps in the preparation of secondary life potions, followed by the most critical step - the fusion of the two melts.

Pour the evenly stirred melt into a slightly larger flask in order, silver leaf grass first, calm the god flower later, because the silver leaf grass is in front of the formula, and then gently shake to let the two melts fully fuse.

This step is the most critical, each step can not be bad, the pouring order, the interval between pouring, and the frequency of shaking must be correct, a small flaw will not make the elixir refining, but it will definitely affect the quality of the potion, but if each step is a little worse, it will definitely fail to accumulate.

Ye Qing was very unlucky, he didn't know which step was wrong, he shook it lightly for a while, and the two melts fused, but they failed.

This is because the color of the two melts after fusion is silver-gray, not the red of the finished secondary life potion.

If successful, the two melts will have a wonderful reaction with gentle shaking, and the silver and green will merge into a completely unrelated red, and he will turn into a silver-gray, which is a failure, and has no effect at all, not only will it not restore a little health, but will make people feel nausea and vomit.

It's normal for refining to fail, Ye Qing didn't care, anyway, there are three days, you can take your time.

He then didn't immediately start the second experiment, but recalled the experiment he had just done, wrote down each step, and prepared to make a slight change in the next experiment.

After three minutes, he cleaned a set of experimental tools, poured out the residue of the previous melt, and brought water into the laboratory, which was also convenient.

Cool dry the experimental tools, place the second ingredient in two crucibles, and begin to heat and cook.

The previous process is the same, but after the melt is poured into the evaporation dish after filtration, here he changed it, before he started to concentrate about 50 degrees, this time it was changed to 55 degrees, he was ready to change it every time he tried, try more than a dozen times, and always try it right.

Concentrate the two parts of the melt into the drug stock solution again, stir well, pour them into a large flask in turn, and start to shake gently.

Unfortunately, this time it failed, but this time he was somewhat surprised, he saw a small amount of red in the melt, and the other colors were not silver-gray, but silver with green, a strange color.

There is a small amount of red, indicating that there is a certain reaction, Ye Qing knows it in his heart, and starts the third experiment.

This time, when the melt was cooling, he chose a temperature of 60 degrees, even if there was a normal reaction at 55 degrees Celsius before, it means that the correct temperature is above 55 degrees, and he can try the temperature between 55 degrees and 70 degrees Celsius once, and then he can try the best temperature.

This time it was good, half of the color turned red, and although it was the same failure, he was in a good mood.

I have to say that when a person does something seriously, he will not feel that time passes quickly.

The fourth attempt, he chose the temperature sixty-five times, but to his surprise, this time there was no trace of red.

He immediately understood that the temperature was too high, and the temperature was too high, destroying the medicinal properties, so it was a complete failure.

In other words, the optimal temperature is around 60 degrees, maybe one or two degrees lower, maybe one or two degrees higher. But whatever, let's finish the task at 60 degrees first, as for what the perfect temperature is, I will have time to try it slowly in the future, and now I will finish the task first.

At 60 degrees, half of the melt turns red, indicating that the temperature is right, but there may be something wrong with his shaking technique, the frequency is not right, and the next step is to improve in this area.

Next, the fifth, sixth, seventh, each closer to success.

When the ninth experiment, Ye Qing's index finger and thumb pinched the flask, and the wrist shook flexibly and steadily, looking extremely skillful, and the bottom of the flask drew an arc between his shaking, if someone looked carefully, they would be surprised to find that the circle drawn at the bottom of the flask was the same size every time, no more than a little, as if it was fixed like a machine.

However, Ye Qing didn't know that he was watching in surprise as the molten liquid in the flask slowly fused and turned red under his shaking.

First it is a light red, then it becomes darker, then deeper, and finally it becomes a pure red.

He didn't need to look at it, he knew that he had successfully concocted a vial of secondary life potion.
