"Let's go! Come with me to meet someone! Liu Baochang got up and went straight to the shoe rack to change into leather shoes, "You are all about it, he can give you a spoonful of stew alone!" ”

In a courtyard in the countryside on the outskirts, Zhang Yicheng saw a very strange-looking old man, with a bright red and dazzling rosacea nose like hawthorn on his mantis-like cheeks, and his eyes blinking like mung beans. Under Liu Baochang's introduction, Zhang Yicheng learned that this person's name is Yang Qingsheng, an old Chinese medicine doctor, and the adopted son of Yang Zhao's adopted son Yang Liwan is a child adopted by Yang Liwan in 1945, that is, the year of Japan's surrender, so he took such a name. What makes Zhang Yicheng's heart flutter is that this person not only knows the family affairs of the Yang family, but also knows how to tell fortunes and read feng shui in traditional Chinese medicine.

"Grandpa Yang, when he sharpened his knife, he couldn't wake up no matter what, and he slashed me with a knife, and in the end, I stabbed his heart and yang veins with a toothpick to wake him up!" After explaining his intentions, Zhang Yicheng completely described Feng Xiangjing's symptoms and the fact that he was cut to Yang Qingsheng.

"Can't wake up?" After listening to Zhang Yicheng's narration, Yang Qingsheng squinted his little mung bean eyes and pondered for a long time, "It's like yesterday!" Yang Qingsheng frowned and shook his head, "It turns out that there is really such a strange disease!" ”。

"Yesterday?" Zhang Yicheng frowned, "Please ask Grandpa Yang for advice!" ”

"Young man, do you know this person Gu Yin?" Yang Qingsheng blinked and glanced at Zhang Yicheng.

"......Familiar," Zhang Yicheng frowned and thought, "It seems to be ...... The one who invented the compass? ”。

"It's a bit of knowledge...... Yang Qingsheng smiled and nodded......

According to Yang Qingsheng, "Yesterday's Disease" is an ancient disease, and the earliest record of "Yesterday's Disease" can be traced back to the Eastern Han Dynasty.

As early as the two-week period, people's cognition of the phenomenon of reincarnation and rushing of the soul was still in the embryonic stage, because there was no concept of "resentment" at that time, and people often attributed the reason for the phenomenon of the soul haunting, rushing and not being able to reincarnate to the dissatisfaction of the deceased with the burial location and burial goods, and only then would they make waves after death. This also directly led to the prevalence of burial and burial during this period.

Since the beginning of the pre-Qin Dynasty, the concept of "resentment" was born, which is tantamount to a historical leap forward for the number of yin and yang, according to a hexagram book called "Hexagram Yanlu", the first in Chinese history to conduct systematic research on "resentment", and the research results are actually applied to all kinds of sacrifices and rituals called Gu Yin, in Gu Yin's view, "the spirit of the wish, the death is restless", which means that the attachment to the wish, so that people can not die peacefully, "the spirit of the wish" has become the earliest origin of the word "resentment".

As early as the Warring States period, the Chinese invented Si Nan, and Gu Yin discovered the weak response of the magnet to the change of yin and yang almost at the same time, and based on this weak reaction, made the earliest compass in China, called "Si Geng", on the basis of Si Nan.

With the help of "Si Geng", Gu Yin was the first to reveal to people the mysterious connection between resentment and reincarnation: that is, people with different methods of death, age, and gender will have different resentment after death. This discovery overturned the previous statement that "the deceased was not satisfied with the tomb or burial goods, so they would make waves", and at the same time, it also had a positive guiding effect on the development direction of the future sacrifice and rituals, and people began to shift their attention from the tombs and burials to the rituals and rituals themselves. It's just that due to cost limitations, this kind of way of dissipating grievances regardless of the cost can only be the patent of high-ranking officials and nobles, and ordinary people can't afford to toss it anyway.

In the second year of Guanghe of the Great Han Dynasty (179 AD), with the invention and popularization of papermaking, Xu Shiyuan, a Taoist official of Wudou Mido Motoji (1), used low-cost paper to invent a simple, economical and effective way to dissipate grievances, that is, the legendary "Caodu" (the main raw material of papermaking is straw), and its basic principle is to use paper people and paper objects instead of real people and real things for sacrifice, and then add Taoism to resolve grievances, and suddenly reduce the cost of the sacrificial ceremony to the acceptance range of ordinary people, in the development of later generations, Paper figures began to be replaced by magic tools such as charms and puppets (2), and the cost of "grass" was further reduced, and the word "grass" gradually evolved into today's "superdegree".

At the same time as the invention of "grass", a rare strange disease also attracted Xu Shiyuan's attention, the most typical case is the county governor Lu Gu of Yandao County, where Takezhi is located, because he bought a horse and contracted the disease, as long as he stood at the door in the middle of the night and cried wolf, disturbing the neighbors, and "not waking up, there is no way to stop it".

At first, Xu Shiyuan also thought that this was caused by offending some evil ghosts and beasts, but in a conventional way, Xu Shiyuan couldn't see anything on Lu Gu's body, and in desperation, Xu Shiyuan simply gave up the traditional Taoist scheme and deduced Lu Gu's previous life from the innate sixty-four hexagrams, but got a result of "good and happy law, died in panic", which means that this person's previous life "is likely to be engaged in a business related to music and law, and his death is likely to be related to the galloping horse", combining some ancient books with this hexagram, Xu Shiyuan boldly speculated that Lü Gu's previous life was Xue Tan, a famous musician of the Qin State (3).

In the literature, Xue Tan fell from a horse and died on the way to enter the palace for Qin Jinggong Gele, and learned the news that Xue Tan fell from a horse and died in a "generation of famous voices", Qin Jinggong also lamented greatly, although the cause of his death was his own fall from a horse, but after all, it was also a "work injury", so he ordered a thick burial, since it was a thick burial, which naturally also included a large-scale sacrificial ritual, although Gu Yin had already put forward the concept of "resentment" at that time, and the sacrificial method had changed, but due to the limited development of spells, although the sacrificial ritual was huge and luxurious, However, the effect of dispersing grievances is far inferior to the "grass" invented by Xu Shiyuan, resulting in Xue Tan's resentment not completely dissipated.

In the process of studying Lu Gu's case, Xu Shiyuan found through the observation of other souls that any soul that can be reincarnated normally is not 100% free of resentment, as the so-called gold is not enough, no matter how advanced the smelting technology is, it is impossible to practice gold with a purity of 100%, and the same is true for the soul, no matter how huge the Dharma is, it is impossible for the soul to be completely free of resentment, the reason why it can be reincarnated is that the resentment is small enough not to affect reincarnation, and Lu Gu's symptoms are very likely to be because the soul resentment in the previous life is too big. The effect of the sacrificial ritual on dissipating resentment is relatively limited, resulting in its resentment happening to the critical point between being able to reincarnate and not being reincarnated.

In Xu Shiyuan's view, if the speculation that "Lu Gu was Xue Tan in his previous life" is true, then Lu Gu's symptoms should be attributed to the residual resentment in his previous life, and according to the records of ancient books, Xue Tan fell to his death, and the biggest resentment is likely to come from the mournful anger generated by not being able to sing for Qin Jinggong. Xu Shiyuan simply came to a bold inference: not only Lu Gu was the reincarnation of Xue Tan, but even the horse he bought was the reincarnation of the horse that fell to his death, but because the horse did not have a birth date and could not be deduced by the innate sixty-four hexagrams, this inference could not be verified.

At that time, cases similar to Lü Gu were rare, and there was no effective treatment, not even a disease name. After experiencing Lu Gu's case, Xu Shiyuan simply conducted a relatively in-depth study of such symptoms, and came to the conclusion of "resentment", the so-called "root of resentment", refers to a medium that triggers the residual resentment in the previous life, although in the era of no "grass", those souls like Lu Gu who are not dissipated are everywhere, but not everyone will show symptoms, the reason why Lu Gu will get sick is to buy a horse, among them, the role of the horse is the "root of resentment" of Lu Gu's illness. Finally, Xu Shiyuan also gave a general name for such symptoms as "Yesterday's Syndrome", which is the so-called "If you wish to be yesterday, you must use yesterday to solve it." This means that if the resentment is brought about by a previous life, it must be solved against the origin of the previous life, and the "yesterday" here does not refer to "yesterday", but to "yesterday".

"Not every horse is a 'root of resentment', Lu Gu is a county prince, and there is naturally more than one horse in the family, the reason why the newly bought horse can become a 'root of resentment' is probably that this horse is inextricably linked with his previous life!" Yang Qingsheng said, "And the truth is very likely to be the same as Xu Shiyuan's inference, that horse is the reincarnation of the horse that fell to death in Lu Gu's previous life, Xue Tan!" ”

"Do you mean that Feng Xiangjing, like that Lu Gu, has suffered from 'Yesterday's Disease', and that Japanese knife is Feng Xiangjing's 'root of resentment'?" Zhang Yicheng asked.

"As it stands, that's it!" Yang Qingsheng said, "This disease is all due to coincidence, it is rare since ancient times, Xu Shiyuan's treatment method is to infer the congenital sixty-four hexagrams combined with ancient historical books, I don't know the congenital hexagrams, and there are no ancient books, I can give him Feng Xiangjing a diagnosis, just because that period of debt is my old Yang family's family affairs!" According to Yang Qingsheng's view, Feng Xiangjing, like Lu Gu of the Han Dynasty, also encountered the "root of resentment" by chance, which triggered the "Yesterday's Disease", and Feng Xiangjing himself has a 99% probability of being the "reincarnated spirit child" of his adoptive father's adoptive father Yang Zhao.
