The two ingredients start together, one crucible with silver leaf clover and one crucible with Ningshen flower. Different medicinal materials cannot be mixed together at the beginning.

The heating process of the two crucibles took him ten minutes. Although it could increase the temperature of the heating furnace and cook faster, the melt of the material cooked in this way was difficult to meet the requirements.

The molten silver leaf clover is light silver, and the Ningshen flower is light green, which looks nothing to do with the red of the secondary life potion.

Grasp the handle of the crucible and remove the crucible from the heating furnace, place it on a wooden board, and then take two evaporation dishes, filter out the residue with a filter net, and the remaining light silver liquid and light green liquid leak into the two evaporation dishes, and then place it on the heating furnace for heating.

Evaporation dishes are a test tool for concentrated materials. After uniform heating on the furnace, the excess water will be evaporated, leaving only the concentrated material.

The temperature required for concentration does not need to be too high, which is much lower than when the melted material was cooked just now. When the molten liquid in the evaporation dish is evaporated from light silver to silver, it slowly changes from light silver to a certain extent. After reaching a certain level, Ye Qing turns off the furnace fire, clamps the evaporation dish with a plier and puts it aside to cool it aside.

Both parts of the melt were placed aside and cooled to a certain temperature. There was no explanation on the specific temperature of the agent formula, but it was just said that it was certain, which was a bit tricky.

This is the limitation of the times in the dungeon. There is no thermometer, and it depends entirely on experience. This is also the main reason why it is so difficult to become a pharmacist. It is so deceptive.

Ye Qing had no choice but to use experience to estimate that he could only try a evaporation dish when it was about fifty degrees, pick up the evaporation dish and pour the liquid inside into a flat-bottom beaker, and then gently stir it with a glass cup to make the silver melt inside more even.

Put this beaker aside, and he immediately pours the Ningshenhua melt from the evaporation dish on the other side into another flat-bottom beaker and stirs the green melt evenly.

This step is very important. The stirring should be even, not too slow or too fast, and the speed should be evenly slowed.

These are the steps before preparing secondary life potion, and the next is the most critical step - the fusion of two melts.

Pour the evenly stirred melt into a slightly larger flask in sequence, first, and then Ningshenhua. Because the silver leaf clover is in front of the recipe, gently shake it to allow the two melts to fully merge.

This step is the most critical. Each step cannot be bad. The order of pouring, interval between pouring, and shaking amplitude and frequency must be correct. Small flaws will not fail to refine the potion, but will definitely affect the quality of the potion. However, if each step is a little worse, it will definitely fail after accumulation.

Ye Qing was very unfortunate. He didn't know which step was wrong. He shook it gently for a while and the two melts merged, but failed.

Because the color after the two melts are fused is silver-gray, rather than the red of the finished secondary life agent.

If successful, the two melts will have a wonderful reaction with gentle shaking. The silver and green fuse into completely unrelated red, and it turns into silver-gray, which is a failed product, without any effect. If you take it, it will not only not restore some health points, but will instead cause nausea and vomiting.

It is normal for the refining to fail, and Ye Qing didn't care. Anyway, there are three days to take it slowly.

Next, he did not start the second experiment immediately, but recalled the experiment just now, wrote down every step, and prepared to make a little change in the next experiment.

After three minutes, he cleaned a set of experimental tools and poured out the previous melt residue. It was convenient for him to draw water in the laboratory.

Cool dry the experimental tools, put the second portion of the ingredients into two crucibles, and start heating and cooking.

The previous process is the same, but after filtering the melt into the evaporation dish, he changed it here. He started to concentrate about fifty degrees before, but this time he changed it to fifty-five degrees. He planned to change it every time he tried it, and he tried it more than a dozen times, and he could always try it right.

Concentrate the two portions of the melt into the potion solution again, stir well, pour it into a large flask in turn, and start shaking gently.

But unfortunately, this time it failed. However, this time he was 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.

A small amount of red indicates that there is a certain reaction. Ye Qing knew it and started the third experiment.

This time when the melt was cooled, the temperature he chose was sixty degrees. Even though there was a normal reaction in the fifty-five degrees before, it means that the correct temperature was above fifty-five degrees. He could try the temperature between fifty-five degrees and seventy degrees once, and then he could try the best temperature.

This time it was very good, half of the color turned red, and although it failed, 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 was sixty-five times, but what surprised him was that this time there was no redness.

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

That is to say, the optimal temperature is around 60 degrees, maybe one or two degrees lower, or one or two degrees higher. But no matter what, you should use 60 degrees to complete the task first. As for the perfect temperature, if you have time to try it slowly in the future, you should complete the task first.

Half of the melt turned red at 60 degrees, which means the temperature is right, but his shaking method may be problematic, and the frequency is wrong. We need to improve this aspect next.

Next, the fifth, sixth, and seventh, were closer to success every time.

During the ninth experiment, Ye Qing pinched the flask with his index finger and thumb, and his wrist swayed gently and steadily. He looked extremely skillful. He drew a circle of arcs at the bottom of the flask while he was shaking. If someone looked carefully, he would be surprised to find that the circles at the bottom of the flask were the same size every time, not much more, and it seemed to be as fixed as mechanically.

But Ye Qing didn't know that he was watching the melt in the flask slowly merged under his shaking and turned red.

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

Without checking, he knew that he had successfully prepared a bottle of secondary life potion.

But the result of the checking was not as unexpected as he expected, and it was a bottle of secondary life potion:
