At the bottom of the furnace is a knob that controls the amount of oxygen and adjusts it so that the temperature inside the furnace is constant.

Dai Lan's eyes were glued to the color of the temperature display area, keeping it a pale blue color all the time.

From time to time, there is a "crackling" or a temperature similar to that of boiling water, and the pressure valve on the top of the furnace intermittently spews out white mist.

I don't know why, Dai Lan began to be inexplicably nervous, constantly circling around the room, and his palms were covered with sweat.

It stands to reason that the drug equation described in the "Selected Tang Poems" is categorically not wrong, and Uncle Signori's alchemy furnace is also very easy to use, and the powerful trauma medicine should be at hand.

But Dai Lan still has no bottom in his heart. If it fails, the Thor Blade is gone, and the Robertson family is in jeopardy. Of course, Miss Emily's position is even more precarious.

After more than a few months in the Middle Ages, Dai Lan still has respect for the entire Robertson family, although he hated the damned Great Elder Galero very much. He didn't want to see one of Nuoda's families end up like this.

Even without the Robertson family as a backer, he would have a lot of trouble in Dundee City or in the search for Bruno.

Under tremendous pressure, Dai Lan's pharmaceutical products can only succeed and not fail!

Most of the fine sand in the hourglass fell, and two full hours passed silently, and Dai Lan's neck began to stiffen.

"Mr. Dai Lan, according to the heat, it should be about the same." The old butler reminded.

"Yes, that's right." Dai Lan nodded and said, "Can you sense the quality of the medicine that has been refined?" ”

Murray shook his head and said in a deep voice: "My dear Mr. Dai Lan, the frequency formant of this drug is quite low, and coupled with the temperature interference of hundreds of degrees in the furnace, I can't judge it for a while. ”

Dai Lan let out a sigh and sighed, "Okay, I'll have to stop and take a look." ”

Dai Lan took out a popular parchment book from the small leather bag James had given him, which he had bought at the grocery store for seven copper tors.

For the subsequent comparison of medicines, Dai Lan carefully recorded various parameters such as the weight ratio of the medicinal materials, the temperature and pressure in the furnace. At the very beginning of these data, a Roman numeral "I" is written, representing the first version of the trauma medicine.

When recording, Dai Lan kept an eye on it. He didn't use common English or Gerke. And most of the writing is his native language, Huaxia Chinese script. In some key places, he even created his own symbols that only he could understand, and kept them firmly in his heart.

Alchemy is different from steelmaking, the quenching process cannot be carried out, and the temperature in the furnace must be slowly lowered to room temperature, so as to ensure that the useful components of the medicinal materials are not lost.

After nearly half an hour, the heat-sensitive material changed from light blue to green, bright yellow and then deep red, and it was time to remove the drug.

Touching the still warm furnace wall, Dai Lan's heart "knocked" and kept beating.

Turning the handle, I slowly opened the door, and a puff of hot white smoke rushed out. Dai Lan was almost out of breath and coughed vigorously.

What made him happy was that with this heat wave, a burst of fragrant flowers and plants wafted out, which made people indescribably comfortable.

On the one-foot-square tray, there were several thumb-sized red pills scattered on them, and the smooth surface was still glowing under the sunlight.

Dai Lan felt a heat in his head, and then Murray's voice came: "Great! My Mr. Dai Lan. I have just conducted a spectroscopic Fourier analysis, and the composition of this drug is very close to your Yunnan Baiyao in Huaxia, and even the proportion of cellular active enzymes is more reasonable! ”

Dai Lan frowned, and said curiously: "Yunnan Baiyao, that is our Huaxia first-class secret prescription, how do you know its composition?" ”

"Well, that, don't be angry when you say it." The old butler Murray was stunned and said sarcastically: "You underestimate the strength of our British Empire's MI6. Some of the agents got a lot of information about the drug from various sources. Although it is not comprehensive, with MI5's world's most advanced spectroscopic comparison laser and supercomputer system, we still deciphered the prescription of Yunnan Baiyao. Even if there is a slight deviation, the error is definitely less than one thousandth. ”

"Shameless! It's shameless! What has been handed down by our ancestors has been deciphered by you British! Dai Lan rolled her eyes at the air disapprovingly.

"Hehe, when it comes to deciphering and copying technology, your Huaxia Kingdom is the number one in the world!" Murray covered his mouth and laughed.

Dai Lan licked her lips, pointed to the small pills in the tray and said, "Do you think this medicine can be used well?" ”

Seeing Dai Lan divert the topic, Murray tried his best not to laugh out loud, and said seriously: "Well, I don't know about this." Why don't you find a dog to try? ”

Dai Lan scolded in his heart: If you say it, you don't say it!

The young man read the original text of the book several times, and felt that it was still not reliable enough. Because when describing the temperature in the book, a general range is used, presumably the author is not sure which temperature is the most suitable.

This is not difficult to understand, after all, the book was written before the Middle Ages. At that time, I didn't know much about the concept of temperature, let alone how to artificially control it.

To refine this batch of pills, Dai Lan only used one-third of the raw materials. He simply divided the remaining herbs into two parts, and refined them at different temperatures, labeled "II" and "III" respectively.

Now he can test with confidence.

By the time all the medication was done, it was late at night. The moon climbed the branches, and a few dogs barked in the distant crops. Dai Lan's stomach also began to growl.

Packed all the medicines separately, touched a few cold raw potatoes from the indoor cellar and threw them into the alchemy furnace to heat, and in a short time, the roasted potatoes with golden mouths were placed in front of Dai Lan.

This is probably the first time in human history that an alchemy furnace has been used as a cook's oven.

The most familiar with this kind of trauma and trauma medicine is the James who licked blood on the tip of the knife. It would be more appropriate to let him preside over the drug test. At the same time, according to James's experience, it can also be compared with the most popular Jacob family trauma drugs on the market.

If the medicine he refined was superior, the Robertson family's borrowing crisis could be solved.

Thinking about tomorrow's drug test, Dai Lan felt excited. But due to mental tension all day, my head hit the pillow and fell into a groggy sleep.

He didn't know that on the other side of the corridor outside the door, Rachel had already poked out half of her head, and a pair of big watery eyes were staring at the glimmer of fire shining from under the door of Dai Lan's room.
