Chapter 209 Backtracking
Lin Zhiqing almost subconsciously activated her orbicularis oris and orbicularis oculi muscles, revealing a smile that was almost indistinguishable from her usual one.

Just then, Lu Huai spoke up at just the right moment: "Aqing, this does resemble the Brahmagupta model you mentioned before."

Lin Zhiqing smiled and nodded, "That's right."

That's right, if you cut two squares or two rectangles in half, you will indeed get a triangle.

"Is this the geometry you mentioned before?" Lu Huai continued to ask.

"Hmm, imagine it as a house. If you cut it in half at the two opposite corners, that's geometry." Lin Zhiqing picked up the charcoal pencil, ignoring the cold sweat on his body, and began to draw on the diagram.

Where she couldn't see, Jiang Liuyun frowned almost imperceptibly.

……

"I see, Riemannian geometry is truly profound." Lu Huai looked up from the drawing paper, his eyes shining.

"Yes, that's right, numerology is quite profound." Lin Zhiqing stretched.

Seeing this, Lu Huai immediately stood up to say goodbye: "Aqing, you've worked really hard these past few days, you should get some rest."

"I'll have Aunt Mu see you off," Lin Zhiqing said, getting up and calling to Aunt Mu.

Lu Huai walked out of the house and gestured with his chin towards Jiang Liuyun: "It's about time you went to change your dressing too, let's go."

Jiang Liuyun nodded, and didn't forget to tell Lin Zhiqing, "Qing'er, you should get some rest."

After seeing Lin Zhiqing nod, he walked out side by side with Lu Huai.

After the person left, Lin Zhiqing closed the window and then the door, and the smile on her face finally faded.

She leaned against the door and took a deep breath.

Jiang Liuyun?

Who is Jiang Liuyun?

The heir of the Marquis of Zhenyuan, a living Yama on the battlefield, and an outstanding figure among the younger generation of the entire Dasheng Dynasty.

This exceptionally talented young man happens to be... Lin Zhiqing's fiancé.

Thinking of this, Lin Zhiqing finally managed a genuine smile.

However, the mockery in that smile was completely undisguised.

She sat down at the table, flipped the piece of paper with the triangle drawn on it over, picked up her charcoal pencil, and wrote a large "Jiang Liuyun" on it.

Does Jiang Liuyun truly like his fiancée, "Lin Zhiqing"?
With this question in mind, Lin Zhiqing began to recall carefully.

My impression of Jiang Liuyun dates back to when she first arrived in Dasheng.

At that time, she was not just miserable, she was extremely miserable.

He was falsely accused, imprisoned, and left all alone.

The appearance of Lu Huai, Lu Nanyue, and Jiang Liuyun earned her the qualification to investigate the case.

At that time, time was of the essence, and she didn't even have time to think too much. But now, looking back, she feels that many things don't make sense.

When Lin Zhiqing first escaped danger and talked to Aunt Mu about the Lin family's situation, it was already the second day after the incident.

The next morning, Jiang Liuyun sent someone back to the Zhenyuan Marquis's residence to fetch ginseng and medicine for himself.

But if he really cared about Lin Zhiqing, why didn't he bring her along on the day of her accident?
Even Lu Nanyue brought a medicine box and some of the best medicinal herbs with her.

If he was so anxious that he didn't pay attention to his health, then why didn't he ask about his health at all during the entire investigation?

This is in stark contrast to his later performance.

But for Lin Zhiqing, who was new to the area, Jiang Liuyun was a complete stranger at the time. Lin Zhiqing didn't see Jiang Liuyun from her fiancé's perspective, so she didn't notice this unusual situation.

Moreover, after the apparent culprit was found in the case of her cousin's poisoning, Lin Zhiqing remembered that Jiang Liuyun had come into contact with poisonous smoke when interrogating Biluo in order to help her, so she specially sent medicine over.

Jiang Liuyun looked somewhat surprised when he saw the medicine being delivered.

However, Lin Zhiqing only thought that there was a difference between her behavior and that of the original owner, and did not continue to test her.

Now that she thinks about it, Lin Zhiqing seems to have never understood how the original owner of this body treated Jiang Liuyun, or how Jiang Liuyun treated the original owner of this body.

If the original owner's attitude towards Jiang Liuyun was different from his own, then why did he show a surprised expression?

Besides, there are many suspicious points surrounding Biluo's death that day.

Lin Zhiqing focused her investigation on her cousin's room. Due to her distrust of the Lin family, she chose to have Jiang Liuyun and her cousin interrogate Biluo together.

After Biluo died, Lin Zhiqing focused his suspicions on the Lin family.

After discovering other clues and confirming that the murderer came from the Lin family, Jiang Liuyun was almost no longer a suspect.

Lin Zhiqing was busy proving his innocence at the time and simply didn't have much time to investigate Biluo's affairs.

Looking back now, at that time, the culprit Lin Jingya had not yet revealed herself, and neither my uncle nor my fourth uncle had made a move. The only one who had the opportunity to harm Biluo was Jiang Liuyun.

Why did he target Biluo?
Biluo is the key figure in Lin Zhiqing's exoneration.

If Jiang Liuyun really did kill Biluo, then his purpose must have been to prevent himself from being convicted.

But why?

What reason could make him hate his nominal fiancée so much that he wished she were dead?

To annul the engagement?
Lin Zhiqing pursed her lips. Based on the information she currently had, she couldn't think of any other reason besides annuling the engagement.

Moreover, this reason seems plausible.

In recent years, Marquis Zhenyuan has not only been influential on the battlefield, but his reputation has also been extremely high.

He was particularly praised for treating the disgraced official kindly and not taking advantage of his misfortune to make his son break off his engagement with Lin Zhiqing.

However, this praise is based on Jiang Liuyun's marriage.

Based on her analysis, Jiang Liuyun is dissatisfied with Lin Zhiqing as his fiancée.

But after enduring so many years, earning a reputation for loyalty and righteousness is entirely beneficial to the Zhenyuan Marquis's mansion.

If Lin Zhiqing is kicked aside halfway through, this reputation will be ruined.

From this perspective, if one makes a serious mistake or dies, the marriage will be null and void.

Such a reason could potentially prompt Jiang Liuyun to take action against Biluo.

Lin Zhiqing closed his eyes. The chill in his heart had long since faded, leaving only endless contemplation.

She went through the content she had just compiled again and found almost nothing that made sense.

Upon closer reflection, she recalled several things she had previously overlooked.

For example, she never doubted Lin Jingya's motives for poisoning her cousin and the original owner of the body.

She remembered clearly that, according to Lin Jingya, the reason she resented her cousin was because her cousin had received an invitation to the Spring Banquet.

The reason for the resentment towards the original owner is because the fourth uncle had feelings for the original owner's mother.

This aspect of the original owner's mother can be explained by the portrait in the study.

But where did Lin Jingya get the news that her cousin was going to attend the Spring Banquet?
