"It's poisoning." Leonardo said simply and plainly.

He then restored the body and began to pack his things.

"Poisoned?" Elena was surprised.

"That's right. The coal stove was just a trick, and the real cause of death was drug poisoning. And judging from the results of the autopsy, it should be some kind of biologically extracted toxin."

"Can you find out what kind of poison it is?" Bella asked.

"It takes time." Leonardo replied, "And, tools."

"What tool?" Elena asked, "As long as you can buy it."

With the deep pockets of the Medici family, no matter how expensive things are, they are not a problem.

"I can't buy it." The other shook his head, "Because such a thing does not exist in the world."

"Huh?"

What is it, so rare?

"Because I haven't made it yet."

Leonardo said, pulling out a manuscript from the box.

This is a detailed design drawing.

Both the structure and the lines are very beautiful. It's more of a work of art than a design drawing.

A beautiful painting.

Even if one day it appears on the showcase of the Louvre in Paris, Bella will not be surprised.

"Can it be done?" Elena asked, looking at the drawings.

"As long as the materials are ready, I don't think there should be any big problems." Leonardo said confidently.

It's like a trivial thing, as simple as making a cup of coffee.

"Okay, the Medici will sponsor you, so be sure to do it as soon as possible." Elena said seriously.

"Alright, I'll leave the list of materials behind. When the purchase is complete, I will send it to Mr. Verrocchio's workshop, where I will finish it."

Elena nodded understandingly.

"I've taken a sample of the toxin, so I can bury this lady. May God bring her into heaven soon."

After Leonardo finished speaking, he turned and left.

Lorenzo returned to the bedside and remained by Sofia's side.

Bella accompanied Elena back to her room.

Elena had mixed feelings.

"...... you say," Elena said and stopped, as if she was in a dilemma.

"Are you still worried about your uncle?" Bella could see the tangle in her heart.

Perhaps Mr. Cosimo and Elena did have some contradictions before, but they were not a matter of principle. Elena was only dissatisfied with her father's handling of her brother's feelings.

But in retrospect, it was indeed a bit inappropriate for Elena to ask her father Xingshi for her guilt when she was still unclear about the ins and outs of the matter.

Too impulsive.

And the tone of his speech at that time seemed to be to blame Mr. Cosimo directly for Sophia's death.

Elena did regret it a little.

Bella suggested that she go and apologize to Mr. Cosimo.

Elena was reluctant at first, but after Bella's repeated persuasion, she finally reluctantly agreed to bring a cup of black tea to Mr. Cosimo.

Elena went to her father's room, hesitated for a moment, but plucked up her courage and knocked on the door.

My father was discussing things with the housekeeper.

Seeing the eldest lady enter, Ugo withdrew with great amusement, and closed the door with his hand.

"Ahem—" Elena cleared her throat, "Well, I heard from Miriam, you haven't had a good throat lately, and she made you a cup of black tea. But, she suddenly has something to do, and I ...... I'm afraid that black tea will be wasted, so I'll ...... Only...... I brought it to you by the way."

With that, Elena shoved the black tea onto the table.

"Thank you." Fathers, of course, know the character of their daughters.

"That...... That one...... I did lose my honor today and shouldn't have ...... You shouldn't be yelling at you, but who told you to be so cold? Sophia is so pitiful, even if you don't approve of her and her brother—"

"Elena." Cosimo interrupted his daughter, trying to say something, but couldn't find the right words for a while.

After a while, he let out a long sigh.

"I know you're still dwelling over that," Cosimo's voice was a little helpless, "but believe me, father is doing it for your own good."

"Okay, well, I've heard enough of that. If Bella hadn't asked me to come over...... "Elena turned to leave.

"Elena," Cosimo said in a serious tone, "not me."

Elena didn't answer, just paused, opened the door and walked out.

Ugo returned to the old man's room.

"Miss seems to be sensible." The housekeeper said with a smile.

"Ugh." Cosimo sighed again, "I never said she was ignorant. This child is always stubborn when he is young, and he doesn't know who inherited it."

"I'm getting more and more like Madame."

"Yes, after all, Elena has her blood in her body."

Cosimo looked up, as if recalling the past.

"You really don't have to ...... that."

"No, I don't." "Knowing it will only make them more miserable. Now if you want to complain, let them blame me alone."

Elena returned to her room and saw Bella still waiting for her.

"How's it going?" Bella asked with concern.

"That's it, what else." Elena replied, "But he told me in person that he didn't do it."

"You should be relieved now, right?"

"It's okay, although the old man is not a thing, but he is barely a good person." Elena felt like a stone had been laid down.

Bella remembered that Elena had said something similar when she was at the castle before.

"What the hell is going on, and why are you so at odds with Mr. Cosimo?"

Bella felt that there should be more than just Mr. Lorenzo.

"My mother'......," Elena said calmly, "was gone when I was very young."

"......," Bella was silent.

"It's just gone. However, I don't know where I went, and if I'm still alive."

「……」

"Every time I asked my father about it, he always prevaricated me with various reasons and never answered me directly. Later, my brother and I grew up and felt that we could take on some things. My brother was involved in the family's banking, and I was in charge of running the perfume workshop. When we can all be on our own, I think he should confess the truth to us, right? That's why I'm working so hard, but ......."

Elena spoke, tears streaming down her eyes again.

"I suppose Mr. Cosimo may have a last resort?" Bella stroked Elena's shoulder and comforted.

"No matter what, I'll find out the truth." Elena finally regained her momentum, "Whether it's my mother's affairs or the cause of Sophia's death, I have to find out."

Seeing Elena like this, Bella was finally relieved.

"Ugh." After a while, Elena sighed again, "Judging from the current situation, we can only continue to track down until Mr. Leonardo confirms the type of toxin."

"But," Bella began, "we can start with something else."

"Anything else?"
