At the end of September, after Zhang Cheng's lawyer helped Zhang Cheng spend more than one million dollars to auction off American ginseng, Zhang Cheng did not rush to alchemy and medicine, but first tasted the medicinal properties and tested the vintage, and then used the dead wood spring technique to activate and plant American ginseng into a small medicine garden opened by himself in the vineyard.

Anyway, my cousin was not in a hurry to use it these days, and for the rest of the time, Zhang Cheng began to use the help of the computer to do a lot of calculations every night. According to the size of the main drug, it is most appropriate to calculate how many auxiliary drugs to be matched, furnace temperature, and the number and frequency of adding water.

This is the benefit of the computer age, in the past, it was necessary to use the abacus, abacus, pen, ink, paper and inkstone to calculate and count for several days or even ten days, but now it can be solved in a few hours.

Everything was ready, and Zhang Cheng waited until the first weekend of early October. Not only will there be two days off this weekend, but the second Monday of this month is Columbus Day to commemorate Columbus's discovery of the New World, so that Zhang Cheng will have three days and three nights if he doesn't go out to play, which is enough.

Zhang Cheng took out the Dan furnace he used in his previous life from the Qiankun bag, and the Dan furnace with half gold and half silver as the material, weighing nearly 100 catties, was wiped inside and out, and Zhang Cheng felt extremely familiar when he touched it for the first time, like shaking hands with an old friend he hadn't seen for many years.

The oak scraps of the surrounding hills are left over after the workers make oak barrels, and the way to heat the United States in winter is nothing more than burning electricity, oil, natural gas and firewood - in fact, the Americans burn firewood and the Chinese people use disposable chopsticks not to cut down the primeval forests in the world as some advertise, and the growth cycle of commercial fast-growing forests is only a few years is not a non-renewable resource.

If no one uses disposable chopsticks or paper, the merchants who grow poplars will lose money and cut them down and plant other commercial crops, which is a real blow to forestry and the environment. The United States has a lot of waste of paper and wood, but because of the large amount of commercial fast-growing forestry and the recycling of paper, the original forest has not only been preserved, but the forest coverage rate is not low.

Because coal burning has strict regulations on the emission and filtration of smoke, so the average household does not burn coal directly, and only thermal power plants burn coal - or only those who can be equipped with the most advanced equipment to filter coal soot and dust dare to burn coal. Therefore, it is not surprising that the average American does not know honeycomb coal.

After igniting the firewood at the bottom of the furnace, Zhang Cheng poured the first five-gallon of mineral water into the Dan furnace and waited for the water to be heated. After measuring the water temperature with three thermometer measurements, Zhang Cheng set clock alarms on his mobile phone, and the time span between the first alarm and the last alarm was as long as 30 hours.

Seventeen minutes later, the mobile phone rang for the first time, and Zhang Cheng put the first main medicine, wild ginseng, into the Dan furnace along with several auxiliary medicines.

An hour and thirty-seven minutes later, the alarm went off again, and Zhang Cheng added a gallon of mineral water.

The flame under the Dan furnace has been controlled to burn at a uniform rate, Zhang Cheng has already set up prompts to add water or medicine according to the mobile phone alarm, and after eighteen hours, all the medicines that have been prepared for the herb are all added, and it is also because this piece of Dough wild ginseng is a little older, and it is not possible to boil it for so long to urge all its medicinal properties to be released.

Twenty hours later, the sun rose and set, and Zhang Cheng, who had only eaten some snacks and drinks in the middle, controlled the flame to be half smaller than just now, and the time for adding water became a fixed half-hour liter, and continued to refine the pill with a simmer.

Thirty hours later, the golden sun rose again, and Zhang Cheng no longer added water and firewood, but waited for the flame to go out and meditated and practiced in the same place. It's also a way to relax your mind and body.

Thirty-eight hours later, Zhang Cheng opened his eyes and exhaled the turbidity in his chest to sweep away the physical and mental exhaustion, and at this time, only forty or fifty degrees of residual temperature was left in the Dan furnace, which was just enough to open the furnace.

Open the warm lid of the furnace, a burst of fragrance from the mouth and nose into the spleen and lungs, the medicine in the furnace has been practiced but not all over.

Zhang Cheng took out a silver slender flat spoon from the Qiankun bag, gently scooped up the golden liquid in the semi-solidified state on the Dan furnace, and then carefully poured it into a one-foot-high mutton fat white jade bottle.

The newly combined medicine is in such a semi-coagulated state, and it will slowly harden after a long time, and if it is kneaded into pills according to the amount of each time it hardens, it is an elixir.

After taking out two and a half bottles of semi-solidified golden liquid, there was still a paper-thin layer of golden liquid on top of it, which could no longer be fished out. Under the golden liquid, you can see that there is only some semi-congealed black liquid left, which is blocked by the paper-thin golden liquid and suppresses the strange taste, if the golden liquid is a beneficial ingredient to the human body, then the remaining black liquid is the toxin in various drugs and is also a harmful ingredient to the human body.

Of course, these toxins cannot be left, Zhang Cheng dug a soil pit in the ground and poured them all into it, and the plant toxins can still be degraded by the soil.

After cleaning up the temporary alchemy and medicine site, Zhang Cheng cleaned the Dan furnace with clean water inside and out, and wiped the Dan furnace dry little by little with a cotton cloth.

"Old man, I've worked hard for you again." After holding the Dan furnace, Zhang Cheng took it back to the Qiankun bag.

After a month of hard work in his spare time, he got two bottles of semi-open pulse drinking medicine, which was half more than Zhang Cheng expected before opening the furnace. According to the calculation that a person can open up the eight veins of the Qi Jing by taking three tablespoons of medicine in three days, the Kaimai Drink refined this time can cultivate about 50 martial arts wizards who are unique in ten thousand.

Of course, this martial arts wizard is also superior and inferior, Lu Bu is a martial arts wizard, but Pan Feng is also a martial arts wizard.

Although the medicine can not be preserved for hundreds or thousands of years, it can still guarantee the efficacy of the medicine within a hundred years of sealed storage in a jade bottle, and the medicinal properties will slowly pass and weaken after a hundred years until deterioration occurs.

In addition, this time, Zhang Cheng had the impression that it was the third time to refine the Open Pulse Drink, and it was about the assistance of the computer to accurately dispense the medicine, and this time it was also the most common to combine the Open Pulse Drink, which almost reached the sum of the number of refining the Open Pulse Drink twice in the previous life, and it was a success, Zhang Cheng felt very proud of this, and the craft was not rusty, or with the help of the Dream Sutra, the last time the medicine was refined, it seemed that it was yesterday.

What is more troublesome than refining medicine is the experimental medicinal properties, which are similar to modern medicine, after the finished medicine is refined, animal experiments must be done first, animal experiments are no problem, and then human experiments are proven to be effective and safe, before they can be given to my cousin.

Animals are okay, and it is okay to have money to buy tigers, lions, pythons, and crocodiles in the United States, but where to find humans who are willing to take medicine?

In the past, after Zhang Chenglu had a few spells, those who were willing to come to try the immortal medicine were afraid that they would be able to expel a few miles. Now I'm afraid I'm going to have to put some effort into doing this kind of thing.
