He Luo's inheritance has a lot of origins, and what he has learned is the orthodox innate way of the Immortal Dao. This was originally the ancestor of the world's Dao, and his cultivation to the highest depths could even be like heaven and earth and even the universe. But this arithmetic has always been mysterious and obscure, and it has been difficult to pass on since ancient times.

In his opinion, although what Gui Yuan talked about was closer to the practical path than the heaven and earth avenue, it was rare to be self-contained, and the context was clear and easy to use, and there was something wonderful about it, which could supplement what he had learned. So he asked again and again, and Gui Yuan also happened to have the intention to show his talent to the judges, and he picked and chose some practical and interesting things that did not arouse too much suspicion and told He Luo.

"The connection between cause and effect in the world is so delicate that even if the cause is exhausted, it may not be possible to calculate the effect. And knowing the effect does not mean that the cause can be reversed. ”

Gui Yuan pointed out a page in the record book to He Luo, "This is my note on improving the preparation method of the Qingling Pill. ”

He Luo looked at the place she was pointing, and sure enough, a lot of data was densely recorded with strange symbols.

Gui Yuan continued: "The Qingling Pill is an elixir that nourishes spiritual energy, which can help the cultivation of qi and the cultivation of disciples in the foundation building period. It's a pity that this flavor pill is easy to refine and difficult to become, it is made of several kinds of main medicines that have the five elements of gold, wood, water, fire and earth respectively, the subtleties are difficult to grasp, not to mention the high rate of waste pills, even if it finally becomes a pill, the five elements of the qi in it are often not balanced enough, and the medicinal properties are greatly reduced.

"I took a total of more than 100 of these Spiritual Pills, and then carefully recorded the difference in the spiritual power of each of them. ”

Gui Yuan flipped the relevant records to He Luo, and she pointed her finger at the last line and explained carefully: "You see, according to the results of the final record, among the hundred pills, the water spirit power is the most insufficient, a total of fourteen, and the number of wood fire gold spirit power is almost the same, ten pieces, ten pieces and eleven pieces respectively. However, the elixir with insufficient spiritual power of the earth line is the least, only five. ”

Gui Yuan looked at He Luo, who was half a head shorter than him, with a smile on his face, and found the rare joy of educating children, "If you were a Dan Master, how would you use this record to deduce cause and effect to improve Dan Fang?"

He Luo was stunned for a moment and did not answer immediately, although he didn't understand alchemy, but this question seemed to be clear at a glance, the water line lacked the most, and the earth line lacked the least, so naturally the proportion of some water-attribute herbs should be increased. However, since Gui Yuan asked so, the answer would naturally not be so simple.

Gui Yuan didn't wait for him to think deeply before continuing to say: "I reverse the cause, and I feel that we need to increase the proportion of herbs for the spiritual power of the earth line first, not the water line. ”

A flash of inspiration flashed in He Luo's mind, "Ah, yes, why didn't I think of it at first, it was the waste pill rate." ”

"Exactly. Gui Yuan also admired He Luo's quick reaction in his heart, "The data of Tuxing's spiritual power seems to be the most problematic, it doesn't really mean that this kind of spiritual energy in the raw materials is enough." In fact, it is because the central earth is very important to the formation rate of the Qingling Pill, and the lack of other spiritual qi is just a lack of medicinal power, but it can always successfully refine the pill, but if the earth-based spiritual qi herb is lacking, it cannot unify the five elements, and most of the refining is a waste pill. ”

"Most of the pills that lack soil have been refined and wasted, and they have not been able to become pills. This is the real reason why there are only five of the finished products of the Qingling Pill. ”

He Luo laughed sincerely, as if a child had eaten a candy with a novel taste, "Although it is a small way, it is really interesting." ”

Gui Yuan didn't care about him either, and gave another example, "When two armies fight, increasing the thickness of the armor can effectively increase resistance, but it will also cause inconvenience due to excessive weight, so the best choice is to strengthen the most lethal parts." The emperor ordered the armor of the generals who had returned from a hundred battles to be examined, and found that the armor on the arms and legs was scarred, followed by the cuirass, and the helmet was the least damaged. “

He Luo raised his eyebrows, "Because the person with a head injury died directly on the battlefield, and there was no chance to come back in armor." ”

"That's why reinforcing the helmet that looks the least problematic is the right way to improve the soldiers' chances of survival. ”

She concluded: "I call this survivorship bias. We also remind ourselves from time to time that what we see is often only part of the truth, but if we ignore the missing part of the past, we are afraid that it will be very wrong. ”

He Luo nodded and said solemnly: "My generation is still introspecting at that time and working hard to train himself, so that he can fully grasp the cause and effect like the ancient powers. "He usually looks like a child, but when he says this, he is very serious.

Although Gui Yuan is a big fan of quantum theory, and does not agree with the determinism of knowing all cause and effect, he also knows that there are many magical peculiarities in this world. She heard that the mysterious Immortal Sect disciple in front of her had faintly counted himself in the category of "my generation", so she hurriedly struck while the iron was hot and asked many questions. Although He Luo couldn't tell her the true method of cultivation, there was no obstacle to learning from the same way. The Immortal Dao is inherently mysterious, just "the number of the Great Yan is fifty, and its use is forty and nine" There are countless learnings in this sentence, which seems simple and easy to understand, but every word can be extended for three days and three nights. One of them spoke vividly, the other listened interestingly, and the more they talked, the more they entered the alley, and they both felt that it was much more pleasing to each other.

In the end, He Luo returned to his usual smiling demeanor, but said meaningfully: "It's a pity that I can't figure out the origin and destination of the two young ladies. After saying that, he turned around and said goodbye, and sang all the way to climb the branches and break the willows.

Longan vaguely made out that it seemed to be a poem,

Xinghai Fucha invites the bright moon, and Yunshan Imperial Sword visits Cuiwei.

Only then did he drink the new ripe wine in the world, and look for the old Fangfei on the fairy road.

The cinnamon branches in the nine-fold sky are cold, and the three-life stone is dreaming back.

The people of the past have gone to the old garden, and the green cliff is still waiting for the white deer to return.

She pondered the poetry, but she was at a loss to grasp the point. Thinking about it, it shouldn't be a bad thing for the judges to turn around, so I don't know how many points can be added.

It's just that now the day of opening the mountain gate is not far away, and her cultivation is also at a critical time, so too many things need to be arranged one by one. Longan was already a little distressed after wasting half a day, so he left in a hurry.

========= the words of the author divide the line ==============

Bowing to thank everyone for their support, the absent day was bathed in a happy reward rain, and the second level of the 500 collection achievement was achieved.

So I got up at 6 a.m. with great motivation and insisted on delivering the Sunday chapter (definitely not because I couldn't sleep because of jet lag). In the next few days, I have to go to eat, eat, buy, buy, and the fairy market of Kwai Ying Xianyuan once every five years is also going to open. Osmanthus longan and bright moon fairy are waving small handkerchiefs, please come and cheer more!
