In this report letter, Ma Guilan not only told a very secret story, but also left clues and evidence. According to Ma Guilan's instructions, as long as the person who gets this reminder letter will understand the origin and source of those pieces of evidence.

The first is the most important hairpin for Taoist priests, that is, the hairpin for Emperor Jiajing. Not only is it pure gold, but also an inconspicuous place on it is engraved with the words "Miaozhen" two small seal fonts, and only such an emperor in the entire Ming Dynasty has this kind of hairpin. This hairpin is not only unique and has no semicolon, but no one will dare to pretend to be it. Pure gold jewelry is not nothing, but the use of pure gold jewelry by men can only prove that this person has a particularly high status. Whether it is a noble or a minister of civil and military affairs, as long as it is a person of status, he does not dare to be too public. Although the feudal lords who lived in their own fiefdoms had no scruples, they did not dare to openly use pure gold ornaments. The public use of male pure gold jewelry is equivalent to publicly proving that he is the only person in the world, that is, the emperor.

Although Emperor Jiajing lived almost the same life as a Taoist priest in his later years, he was also different from ordinary Taoist priests in details. In order to let people who knew and did not know Emperor Jiajing know who Emperor Jiajing was as soon as they saw Emperor Jiajing, the eunuchs tried all the ways before they came up with this method. It can not only not affect Emperor Jiajing's mood, but also let the people in the palace know that this is the master as soon as they see Emperor Jiajing. In order to make everyone recognize who Emperor Jiajing was when they saw it, the eunuchs persuaded Emperor Jiajing to use pure gold Taoist hairpins. For this reason, the great eunuchs did not put a lot of thought into it, first of all, they had to persuade the group of Taoist priests who were serving Emperor Jiajing in the palace, so that they could speak in unison. The Taoist priests would not only ask the gods but also fortune-telling, and the great eunuchs asked them to tell Emperor Jiajing directly, that Emperor Jiajing had many wooden characters, and that he should try not to use wooden objects close to him when he was cultivating. Emperor Jiajing was very convinced of this, and rarely used wooden ones except for the table used for the chair he sat on. As for the jade, the great eunuchs made a small mistake, which deliberately made Emperor Jiajing dissatisfied with the jade jewelry. When a little Taoist priest visited Emperor Jiajing with his master, he inserted a jade hairpin on his head, indicating that it was deliberately arranged. As the little Taoist priest bowed and got up and other big actions, this jade hairpin that had already been done with hands and feet not only fell off, which made the little Taoist very embarrassed, but also this jade hairpin was broken. Although Emperor Jiajing did not blame the little Taoist priest in person, Emperor Jiajing replaced all the jade hairpins he used afterwards, and Emperor Jiajing didn't want to lose his temper in front of everyone. Therefore, Emperor Jiajing, under everyone's step-by-step arrangement, finally agreed to use pure gold Taoist hairpins. This pure blonde hairpin has also become a strong piece of evidence, a strong physical evidence that Emperor Jiajing is the father of Ning'er's child.

Children's clothes are not only made of tribute fabrics in the palace, but also authentic craftsmanship of the Needlework Bureau. This set of yellowed and slightly discolored small clothes is enough to prove that this thing comes from the palace and is not from the people, that is to say, this child is not an ordinary child. Dacade cloth bags are used to wrap children, especially newborn children. There were not only the child's body fluids but also some blood stains on the package, I don't know if it was the child's or the child's mother, Ning'er. But this brocade wrap is also not simple, the fabric and craftsmanship on it are not ordinary, even if the pattern is still a dragon. This is a package that can only be used by the royal prince, and it can also prove that this child is not only from the palace, but also a small master with status and status. On top of that, there is also a small footprint on this package, a bloody footprint that a child accidentally imprinted on the package with blood. Not only is this footprint very clear, but there is no other contamination in the vicinity, indicating that this bloody footprint was deliberately imprinted. Qin Tai thought of Ma Guilan's words, and boldly guessed that this was deliberately printed on the package by Ma Guilan when everyone was not paying attention. Palm prints and footprints are the same, and everyone is different, so they play a very important role in solving crimes. Qin Tai had used palm prints to catch the murderer many times, so he understood that this footprint played a great role in this case. Although this footprint is a newborn child's, as the child grows up, the foot will grow, but the lines on it will not change much. According to this footprint, it can be determined whether the reincarnated celestial master, who is now almost called a living immortal among the people, is really that child.

Based on this bloody footprint, Qin Tai guessed that the blood stains on the brocade might be Ning Er's. When a woman gives birth, she will bleed, and this blood is normal for the mother. Besides, it is impossible for a newborn child to produce so much blood, and if there is so much blood, the child will not be saved. The blood stains on the brocade could only be the child or the child's mother, so Qin Tai boldly guessed that the blood on it must have been left by the child's mother, Ning Er.

Ma Guilan only kept a total of three items, but these three items are not simple, and they explain the identities and origins of these three. Emperor Jiajing's hairpin, Ning'er's blood, the child's footprints, and the things that can only be used by the masters in the palace are enough. Once these things are exposed, not only will Emperor Jiajing's face have no place to put it, the dignity of the imperial family will be gone, and even the reputation of the imperial court and the government will be greatly reduced. Ma Guilan knew the seriousness of this matter, so she didn't dare to collect it closely, so that the things were not searched by Ning'er, and indirectly saved Ma Guilan's life.

Qin Tai basically knew the ins and outs of the matter, but he still had a few questions that he couldn't solve. First, how does Ma Guilan keep these things. It is believed that Ma Guilan explained that Ma Guilan kept these things separately. Where does Ma Guilan put her things so that she can be safe and assured, and what have been kept well for so many years? Second, how did Ma Guilan get Ning'er to agree to go back here? Isn't the thing in Ma Guilan's hand the last thing Ning'er wants to see? As long as Ma Guilan doesn't die, this thing is not exposed, and it will be over, why did Ning'er agree to let Ma Guilan come back? Anyone would wonder if Ma Guilan's return would make it more likely to expose the secret? If anyone else was Ning'er, she would definitely not let Ma Guilan come back. What is Ning'er's purpose in doing this, does Ning'er have any other plans? Third, Ma Guilan has been guarded in this small place for a long time, how does Ma Guilan know about things outside? Who told Ma Guilan the secret of the Divine Cult? How many secrets does Ma Guilan know? Fourth, Ma Guilan went from where to the news of the disappearance of the altar owner, so she decided to use this opportunity to leave the place of custody. You must know that Ma Guilan has been pretending to be obedient for so many years, if there is no time to be fully sure, Ma Guilan will not do this. Who told Ma Guilan that the opportunity had come? Who secretly helped Ma Guilan? Who attracted the attention of the organization and allowed Ma Guilan to escape the pursuit of the organization? Fifth, Ma Guilan has secretly returned to her hometown and lived as her sister Ma Yuelan, almost cutting off any contact with her predecessors, and who told Ma Guilan that there have been several major riots outside these days? In addition to the ordinary people in the place where these things occurred, the general government does not know that it is not clear, who told Ma Guilan so powerfully?

Qin Tai not only raised questions, but also tried to explain the problem according to what he knew about Ma Guilan. At this time, Qin Tai was not only Qin Tai, but also had Ma Guilan's way of thinking, or Qin Tai used Ma Guilan's thinking to think about problems. Although this substitution method is incomprehensible, Qin Tai feels that it is very practical to do so, and by thinking about the problem with the thinking of the criminal or the insider, he can deduce the mentality and criminal process of the criminal or the insider, so as to prove and implement the conjecture in Qin Tai's heart. Qin Tai fantasized about himself as Ma Guilan, a person exactly like himself mentioned in Ma Guilan's letter, and then thought about these questions, hoping to find clues or answers.

A girl appeared in Qin Tai's mind, a girl who was only seven or eight years old. She was not only naïve but also poor, in order to be able to eat enough, in order to be able to live a good life, she agreed to her mother to go to other places. When she got into a carriage with a group of children of about her age, she was still daydreaming, a daydream that would never come true.

As soon as the picture turned, the girl came to a strange place, a big place that was tall and big enough to scare people to death. The people there are not only eccentric, but also fierce. The men are gloomy, the women are fierce, and when they see them, they either beat or scold, and they don't feed them. These people repeatedly warned the children that they were just slaves, no longer human beings and more undignified, and that if they did not obey, they would be beaten to death or thrown into the pile of dead men and starved to death. The girl was scared and cried, but no one paid attention, and several familiar girls hugged each other in pain and comforted each other.
