From these two doubts and the series of footprints, Fu Jun came to a conclusion:

The mysterious woman entered through the window of the small study, secretly sprinkled a puddle of oil on the side of the flower bed, and cut off the branches of Wang's favorite begonias.

Huaisu once recalled that Wang gave a soft "huh" before slipping. At this time, I thought that Wang should have walked here, saw that the flower branches were wrong, and stepped forward to check, and the pool of oil played a role at that time. Wang stepped on the frozen oil stains and almost slipped, but fortunately was supported by Shen's mother and Huaisu.

At this point, Fu Jun came to a conclusion and a doubt.

The conclusion is: the mysterious woman is very familiar with Wang's preferences, knows that Wang likes to walk by the flower bed in the east corner after dinner, and attaches great importance to the sprinkling of golden begonias, so she will deliberately destroy the flower branches to lead Wang to step on the oil traces.

However, this is also where the suspicion arises: Is this woman going to great lengths and taking great risks just to let Wang slip on it without danger?

You need to know that there are a bunch of maids and servants accompanying Wang's walk, and there are people to support him, how can he slip lightly?

The answer is clearly no.

So, what is her purpose?

Wang slipped and fell shortly after, but soon became seriously ill and soon died. Is it a coincidence that the time from the onset of illness to the death of the child is very short?

Fu Jun clearly remembered that Lu Yizheng, who was skilled in medicine, once said that the Wang family was just a little weak, and he only needed to wait for the spring of the next year to be fine. And from the day of Wang's death to the beginning of spring, it was only ten days. And Wang's illness was critically ill just before the beginning of spring, is this a coincidence?

No, it can't be a coincidence.

The mysterious woman's purpose of taking a risk and climbing through the window will definitely not be as simple as just letting the Wang family slide. In particular, the woman was very familiar with the life and rest of the Wang family, and she must have known that Mother Shen and the others were very protective of the Wang family, and the act of sprinkling oil was blind, which was very inconsistent with her previous actions of deliberately loosening the window.

At this point, the answer is almost imminent.

The purpose of the mysterious woman entering through the window must be for a bigger scheme, such as putting the Wang family and the place of death.

However, what is the connection between putting Wang to death and trying his best to cause Wang to slip?

Fu Jun recalled again that Huaisu and Shen's mother both said that after Wang slid a little, he was helped into the room, and then drank medicine, and soon said that he was sleepy and went to bed to rest. By the time they smelled blood, Wang had already fainted in a pool of blood.

As far as Fu Jun knew, the medicine prescribed by Doctor Lu did have some soothing ingredients, and Wang sometimes slept for a while. It's just that in Huaisu and Shen's mother's description, Wang's sleepiness that day was heavier than usual, and he was sleepy after drinking the medicine for a while.

Fu Jun's intuition was: there must be something wrong with the medicine that day.

However, after the fact, Dr. Lu had carefully investigated the dregs and found no suspicions. And all the people and things related to the boiling of medicine, Fu Geng has also sent someone to check, and there is no problem.

From this, Fu Jun can only deduce a seemingly impossible conclusion:

The poison is directly in the medicinal decoction. And after the Wang family used the medicine bowl, he handed it over and washed it, and the traces on it had been annihilated.

This is the conclusion reached using the method of elimination.

According to this inference, another suspicion arises:

How did the woman put the poison directly into the medicinal soup?

During the boiling process of Wang's medicine, Shen's mother and others took care of the whole process, and unless someone cooperated, it was impossible for the woman to put the medicine in the bowl.

However, if there had been such an internal response, the woman would not have had to spend so long loosening the window of the courtyard wall of the small study, and going through the window to cut off the branches and sprinkle them with oil. Wouldn't it be safer to do so for such reasons?

From this, it can be seen that at least in Wang's room, this woman has no internal response. Even the person who nailed the window, Fu Jun thought that the possibility of this person being used was much higher than the possibility of internal response.

Then, this poisonous feces must have been put into the decoction by the woman herself, but the timing was very clever and unnoticed.

Based on the facts he knew, Fu Jun had a rough inference, and this inference was also drawn from the mysterious woman's seemingly unjustified behavior:

The mysterious woman's main purpose in making Wang slip was probably to cause chaos.

According to Shen's mother's later recollection, when Wang slid away, everyone was frightened, she and Huai Su both screamed, and there was a lot of chaos in Qiuxi House. At that time, Wang's medicine had just been boiled, and according to Lan Ze, who was boiling the medicine, recalled, after she put the medicine on the table, she heard a shouting outside, saying that her wife had slipped and fell, and she was so frightened that she hurriedly ran out.

I'm afraid that's what the mysterious woman wanted.

When that chaos appeared, everyone ran to Wang's side, there was no one in the house, the medicine was on the table, and this was the best time to take the medicine.

Fu Jun even thought that as long as the poison could be poisoned, whether it was put in a bowl or in a crockpot where the potion was boiled, the woman didn't care.

Her purpose is to poison her, and as for whether someone will find out afterwards, she shouldn't have thought about it so much. Judging from the way she cut off the flower branches and sprinkled grease stains, she was completely reckless, even if she was found out afterwards, she didn't care.

In addition, Fu Jun also believed that the medicine must be colorless and odorless, and it was very difficult to find. This idea was only thought of by Shen's mother after she handed over Wang's medicine box to her.

Since there is a secret medicine of Nanshan Kingdom in this world, there must be other secret medicines. As long as the right medicine is chosen, Wang's red disease will be ten points worse, and Wang's already weak body will be unable to bear it due to excessive blood loss.

However, all of the above is just Fu Jun's inference after all. There was a lack of evidence, and no further information could be obtained from Wang's body. No matter how precise Fu Jun's inference is, it cannot be confirmed.

If this inference is true, then the second suspicion arises:

That woman is not a person from Qiu Xiju, and she has to find an opportunity to poison her, so she can only find an opportunity by observing the situation of Qiu Xiju at all times.

So, where did she observe the movement of Qiu Xiju? Fu Jun believed that it was impossible for a raw maid or servant woman to be exposed to the noses of Mother Shen and Huaisu for a long time, and the probability of being discovered was too high, and it was impossible for that woman to do such a rash thing after risking to climb through the window.

Then, she must find a place where she can not only hide, but also observe the movements of Qiu Xiju at all times, where is this place?

Regarding this question, Fu Jun thought about it for several days, until she suddenly remembered the locked room in Fu Geng's small study, and then suddenly it dawned.

She found an excuse to let Fu Geng open the room, and then found an opportunity to take Fu Geng, and did a simple survey in that room, and as a result, by the window drawer of the room, she found a woman's long hair. And the window in that room was as Fu Jun expected, the latch was not plugged in, but just closed. (To be continued.) )
