This person is actually a trust arranged by Zhang Hua, named Wang Fei, a native of Longshan City, because his qualifications are not high, so he was not accepted by the Longshan faction, and can only rely on some entry-level exercises to cultivate by himself, at present, there are only nine levels of Qi refining cultivation, there are many such people in Longshan City, most of them are looking for a shop in Longshan City as a buddy, and under normal circumstances, the income is also good, which is much stronger than the general casual cultivation.

And Wang Fei was a guy on the other side of the Earth Fire Furnace Refining Room that Zhang Hua used just now, Zhang Hua promised to give Wang Fei a few elixirs as a reward when the matter was completed, and he followed.

Although Zhang Hua said that he didn't have any spirit stones on his body now, he still had a lot of other pills and spirit weapons that he had refined, in fact, if Zhang Hua sold these pills and spirit weapons, he could also exchange them for a few medium-grade spirit stones, but the value of these things was too low to meet Zhang Hua's requirements at all.

In front of the onlookers, Zhang Hua taught Wang Fei how to use the thermometer, and then watched Wang Fei start to use it according to Zhang Hua's teachings.

Originally, the examiner standing next to him was ready to stop him, but after Zhang Hua stuffed a bottle of elixir, he turned a blind eye, in fact, there are people who love to watch the excitement wherever he goes. No, when Zhang Hua started to greet everyone, a group of people were gathered around, and when Wang Fei came in, there were more and more people around.

In fact, even among those who didn't come around, there were some people who used their divine senses to keep an eye on the situation here. After all, they are all cultivators, not only have good eyesight, but for those who are in a high realm, their own divine sense can also replace vision, and as long as these masters use their divine sense to check, it is easy to know what is happening in the crowd.

Wang Fei began to use his true qi to raise the temperature in the alchemy furnace, originally for people in the qi refining period, only a few people chose to refine the pill by themselves, and the biggest problem was that most of them were wasted when refining the pill, and it was likely that it would take ten parts of the materials to refine a pill in the end, which would lead to the end being cheaper than buying the pill.

According to Zhang Hua's analysis, this situation is actually very simple, the most important thing is that the monk's divine sense in the qi refining period is too weak, and there is no way to use the divine sense to go deep into the alchemy furnace with extremely high temperature, and there is no way to observe the temperature in the alchemy furnace at all times, even if it is observed, it can only rely on the color of the flame in the furnace to observe, this kind of observation requires a certain amount of experience, and even if there is experience, it is difficult to achieve accurate control.

Therefore, as long as you use Zhang Hua's thermometer, you can intuitively observe the temperature in the alchemy furnace.

Soon, Wang Fei had already raised the temperature to about 1,800 degrees, and then Wang Fei began to slowly control the temperature drop, and finally extinguished the true fire in the alchemy furnace, and then took out a snow-white True Yang Jade from the furnace.

The crowd of onlookers let out a sound of amazement, and for a while the people around them began to talk about it, and the shopkeepers of some of the shops had already begun to discuss the value of this thermometer.

At this time, Zhang Hua spoke again: "Everyone, be quiet. ”

After seeing that everyone was focusing on themselves again, Zhang Hua spoke again: "Everyone, I still have two other things, both of which can be used in alchemy, and I will invite this little brother later." ”

Zhang Hua pointed at Wang Fei and said, "Let him participate in the alchemy competition in the future, if you are interested, you can take a look at it together to see if these things I brought can work." ”

In fact, Zhang Hua has been busy refining three things in the past two days, one is this thermometer, one is an accurate balance scale, and the other is a calculator for accurate timing.

To be honest, these three things are not special things for people on Earth, but in this world these three things fill the gap in the corresponding field.

Doesn't it mean that the cultivators of this world can't keep time? Weigh and observe the temperature, but their timing is relatively calculated according to the movement of the sun, and even the second is rarely calculated, of course, the second in this world is not the smallest unit of time, and there are time units such as what flick of the finger and the instant, but this is all imaginary fingers, no one will accurately calculate how many flicks of the fingers and how many moments they have passed, most people are still in quarters of an hour, and even the minutes are not calculated, and the relatively accurate time calculation required for alchemy has become a problem.

Weighing is also, although there is a scale in this world, but there are few scales here that can be accurate to grams, so Zhang Hua's scale that can be accurate to milligrams is extraordinary, if everyone can control the dosage of elixir more accurately in the future alchemy, there will not be so many waste pills.

The thermometer can control the temperature at the time of alchemy, and for the alchemy method that used to rely on experience or divine sense to confirm the temperature, in the case of using a thermometer, the success rate of alchemy will also be greatly improved.

Zhang Hua made these three high-precision measuring instruments, although it is far from the highest level of measurement on the earth, but it has surpassed the world for an era.

Originally, the organizer of the alchemy competition didn't want to break the rules for Zhang Hua, but he couldn't stand the constant noise of these onlookers, and some people in the organizer were also a little interested in Zhang Hua's few things, so they agreed to Zhang Hua, but he also said that even if Zhang Hua wins, there will be no prizes.

Zhang Hua didn't care about those prizes, and their value was just like two medium-grade spirit stones, although the prizes were still relatively attractive to ordinary monks, for people like Zhang Hua who spent money lavishly, these two medium-grade spirit stones were not useful at all.

After passing the previous two rounds of tests, Zhang Hua actually had the qualifications to open the furnace for alchemy, and this time the test was the most difficult pill to refine in the Qi refining period, called Tongmai Dan.

This kind of pill is actually an auxiliary pill used by monks in the Qi refining period to break through the realm, but it is relatively difficult to refine itself, and it will often refine the waste pill, so the value of this pill has always been very high.

Zhang Hua received the pill prescription provided by the organizer, and after Zhang Hua looked at it, he felt that these few things used for measurement could definitely greatly improve the success rate of alchemy in the cultivation realm.

I saw that the Danfang read: two coins for 100-year-old ginseng, three coins for more than 50 years of Dihuzi, five coins for 100-year-old Tonglong grass, one coin for dried chicken heart fruit, half a coin for fritillary mothers, and finally half a penny for 100-year-old Ganoderma lucidum.

Refining method: simmer to catalyze ginseng, ground skin seed, Tonglong grass three moments, then add chicken heart fruit, fritillary, change the fire refining for a moment, and finally add Ganoderma lucidum, and then change the medium fire refining for a moment, Dancheng.

Looking at this kind of unclear Dan Fang, Zhang Hua sighed: "No wonder it is so difficult to cultivate the alchemy in the True Realm, and if it is written so unclearly, it is necessary for people to explore the experience, so that when refining a new elixir, it is difficult to grasp the essence of it at the beginning, which is why alchemy has become so difficult." ”

Zhang Hua retranslated this Dan recipe: 10 grams of 100-year-old ginseng, 15 grams of more than 50-year-old Dihu seeds, 25 grams of 100-year-old Tonglong grass, 5 grams of dried chicken heart fruit, 2.5 grams of fritillary, and finally 2.5 grams of centennial Ganoderma lucidum.

First, use a simmer of 80 degrees to 100 degrees to refine ginseng, ground skin seeds, and Tonglong grass, refine for 45 minutes, let their medicinal power be released, and then add chicken heart fruit and fritillary, then change to a temperature of 180 degrees to 200 degrees for 15 minutes, and finally add Ganoderma lucidum, and then change to a temperature of about 150 degrees for 15 minutes, and finally use the condensation technique to get the elixir.

Give this new Dan Fang to Wang Fei, first teach Wang Fei how to use his balance scale and the calculator for timekeeping, and then let him refine it according to the requirements of the Dan Fang he wrote, and then Zhang Hua will give instructions from the side.

Wang Fei first used the balance to weigh the elixir provided by the organizer, and found that the number of elixirs provided by the organizer was relatively large, about the weight of three parts written on the Danfang, and first separated these elixirs according to the needs of each one, and then Wang Fei began to refine.

To be honest, this is Wang Fei's first alchemy, although Wang Fei works in a place that provides an earth fire refining furnace for monks, and he has also used the earth fire refining furnace when he has nothing to do, but to say that he uses the earth fire furnace to refine some ores, Wang Fei has also done it.

Alchemy is a delicate job, and if there is a slight accident, the elixir will be scrapped, and the spirit stones that bought the elixir will also be scrapped, so Wang Fei really hasn't tried alchemy.

This time it was Zhang Hua who found Wang Fei, and said that he would give a good reward, Wang Fei agreed to come forward as a trust, originally thought that it was just a simple matter of refining Yang Yu into real Yang Jade, even if Zhang Hua didn't give Wang Fei a thermometer, Wang Fei relied on his experience in dealing with refining furnaces for so many years, and he was able to refine such a thing as True Yang Jade, but now Zhang Hua actually asked him to do alchemy, Wang Fei was very unscored.

However, when Wang Fei hesitated, Zhang Hua directly raised the reward to a Zhuji Dan, and now Wang Fei said that he would try everything, after all, Wang Fei was already a monk of the ninth layer of qi refining, and he had been saving spirit stones for the purchase of Zhuji Dan for the past two years.

Focused all his efforts on alchemy, while controlling the temperature in the Dan furnace, while looking at the calculator, time passed little by little, and the medicine in the furnace was also refined into a slightly clear ointment-like substance, and soon it was the last step, but Wang Fei was so nervous that he forgot how to condense the pill for a while.

This is also due to the fact that Wang Fei has no experience in alchemy, and he has very little practice for spells such as condensation, so he will forget it at this time because of nervousness.

But at this moment, Zhang Hua's voice came from Wang Fei's ears: "Concentrate and calm your breath, hold on to one, and gather and form your spirit." Condensation!"

Following Zhang Hua's instructions, Wang Fei also recalled the use of the condensation technique, condensed the true qi on the alchemy furnace, and then said in a low voice: "Condensation." ”

After completion, Wang Fei slowly withdrew his true qi, and the temperature in the alchemy furnace slowly dropped, only to see that at this time, five soybean-sized pills rolled out of the alchemy furnace, each of which was crystal clear, exuding a slight aroma, and the Tongmai Pill was completed.
