Seeing that everyone had already walked cleanly, and Wen Yan comforted Gu Li, who was very grateful with tears in his eyes again, and asked him to take San'er to the room first to rest and suppress the shock, Xie Xiuqi couldn't wait to turn to Erhu: "Erhu, I'm here, but it's for my arson case, according to An Qi, you watched the whole process with my Uncle Lu that day-what's going on?" ”

Xie Xiuqi thought about it, but recounted the suspicions he had told An Qi in the morning.

Erhu nodded, and his face also showed a look of memory: "You are suspicious of Tang County Zunzhi, but the little one has heard Miss Lu and Lord Lu talk about it." It seems that they also have the same suspicions, and Miss Lu is even more convinced that this matter is the work of Tang Xianzun, and the conspiracy to take over the yang - by the way, Miss Lu even thinks that the Fang family may also have a hidden secret. ”

Xie Xiuqi didn't notice Erhu's last sentence, and he had already frowned when he heard the preface: "Then they are still ......."

He asked, puzzled.

Erhu smiled bitterly: "Young master, some things can't be guessed, you have to tell the truth." ”

On the same day, Lord Lu also felt that this case was not big or small, and it was too much of a coincidence. So he instructed the adults in the second room of the county government criminal law to strictly inspect it, and even watched it in person from the side. However, the conclusions reached are also helpless...... I remember that the Torture Room King, who was in charge of the inspection at that time, reciprocated his doubts about Lord Lu in this way-"

The two tigers narrated it eloquently.

"First, if someone wants to artificially accelerate the fire, they can only raise their salary, light more fires, or add fuel to the fire. However, according to the results of the Dharma room, there were no traces of the above in the fire scene: there was no excess firewood and grass ashes, no new fire, and no residue of burning after pouring oil elsewhere, everything was very natural. ”

"And that night it was a strong wind, and the direction was blowing in the direction of the storeroom. In this way, under the wind and fire, the fire is swift and explained. ”

Erhu said helplessly.

Xie Xiuqi groaned, but motioned for Erhu to continue.

Erhu sorted out his thoughts, and continued: "Lord Wang said: Second, and more importantly, if someone does something with his hands and feet, then, under the wind and fire, who can be so magical, control the invisible fire, make it burn just right, and not even leave a trace of it?" ”

"You know, as you said, a little more fierce or a little lighter will make a completely different result, and if there is a conspiracy in it, it is not the god of fire who designed it?"

"Therefore, in the end, the second room of the criminal law can only think that it was a coincidence under the wind and fire, and Lord Lu can only pinch his nose and recognize the identification results."

"And that suspicion is also inaccurate because of this - I haven't found any definite evidence that Tang Xianzun did anything in the arson case, even if there is a suspicion, even if I know that I can use it to counter Tang Xianzun, what is the use?"

In the end, the second tiger said dejectedly.

Xie Xiuqi's face was full of contemplation: "There is no excess firewood and grass ashes, no new fire, and no residue of burning after pouring oil elsewhere?" Firewood and grass ashes and fires are good judgments, if I have to do tricks...... Yes, adding fuel to the fire is the most covert ...... How did the county government inspect the fire where oil had been poured on it? ”

He looked at Erhu inquiringly.

Erhu snorted: "With impurities...... The oil will burn out, but if the oil is splashed somewhere, some microimpurities will remain after incineration, just like the place you splashed, and the impurities can be detected. ”

Xie Xiuqi was suddenly thoughtful, and he couldn't help muttering very subtlely: "So, can't impurities be tested in other places...... But is this the only way to check...... It's easy to think of no impurities...... Fractionation and purification can be ...... It's just that people in this era may not have reached this technology, and maybe they haven't thought of it yet......"

"How do you test the oil stains of the fire in modern times? I seem to have seen it on the Internet, and it seems to be some kind of spectroscopic technology? But I don't understand, and even if I do, there can't be such high-end instruments in ancient times......"

"That's not right! Don't they all say that there are impurities? Yes! Ancient oil is not a highly volatile gasoline after purification and separation in modern times - only gasoline that burns violently and is easily volatilized by high temperatures in the fire will disappear without a trace, and spectroscopic technology is required to detect the traces......"

"So...... There must be some left...... By the way, I can't ......."

Gradually, his eyes slowly brightened.

He pondered for a while, then looked up again and asked, "Is the scene still there?" ”

"Yes." Erhu nodded and said: "Tang Xianzun has always kept it as it is, and he also deliberately built a canopy and sent a special guard to guard it. ”

A hint of coldness flashed in Xie Xiuqi's eyes: "Okay! I expected that! ”

He clapped his hands and smiled.

"Why?" Erhu looked a little confused, and even An Qian and the others, who had been listening quietly on the side, cast curious glances.

Xie Xiuqi smiled slightly: "This case has not passed the court, but it was only settled in private." If you don't keep it as it is, in case the evidence disappears, what will Tang Xian Ling do to blackmail me Uncle Lu? Although my Uncle Lu is a humble gentleman, he will never do such a thing. But a despicable villain, how could he not live the belly of a gentleman with the heart of a villain - in case my family secretly destroys the evidence, wouldn't the Tang County Order be empty? ”

He said softly, his eyes were already flashing with a slight light: "So, before my sister passes through the door, he will definitely stay as it is, and he can't wait to let the county's elders notarize him, he will definitely not do anything during this period." ”

He sneered.

Erhu suddenly realized: "I see, I said that Tang Xianzun was full of food." ”

Xie Xiuqi sneered again: "He is full, but I also want him to be full like this...... A fire burned so coincidentally? If there is no catty in this, I don't believe it...... If I find evidence from it......"

The second tiger was stunned: "But the fire site is strictly guarded by the county government, and it is strictly forbidden for anyone to touch a single grass or tree in it, and we can't get in......"

He snorted.

A strange smile appeared on Xie Xiuqi's face: "Why do you want to enter?" Sometimes, the evidence can be found through simulations...... The fire just needs to be there so that I can extract evidence in the future. ”

He smiled mysteriously and murmured again.

"Can't you find anything unusual other than I set it on fire?"

"Huh...... With the level of civilization in this era, it is natural that only relatively simple and primitive means can be used...... But...... Hehe......"

For a moment, the room was extremely quiet.

Xie Xiuqi seemed to be wandering for nine days, but Erhu and An Qian were also looking at him nervously.

In just half a day, Xie Xiuqi first shocked An Qian with an amazing analysis, and then turned his hands into clouds and rain in Erhu's house.

At this time, although the two of them were very familiar with the young master in front of them, they gradually had an unpredictable and unfathomable feeling, and they were even more convinced. Although I don't know what the young master is muttering just now, and what he is thinking about at this time, the two of them don't dare to come out.

I don't know how long it was quiet, but when Erhu and An Qian were looking at each other, they saw the young master in front of them clasping their palms, and they were already looking at them.

"An Qi Erhu, if I want to make such and such an artifact...... Is it possible to make it? How? ”

I saw that there was a hint of surprise and excitement between his eyebrows, but he pointed at An Qian and Erhu and made a strange comparison. Subsequently, he seemed to feel that he was not clear enough to draw, but it was Erhu who found a pen and paper ruler, and under the careful outline, gradually, several figures were already on the paper.

The second tiger is already in the clouds: "What is this ......?"

He muttered as he stared at the pile of incomparably strange drawings on the paper.

Xie Xiuqi looked at his painting with satisfaction, thought about it, and gradually marked the size. Immediately, he looked at the two tigers An Qian in the fog on his face, and his heart was already full of self-satisfaction - how can you understand modern engineering drawing?

After thinking about it, he looked at Erhu and smiled: "This is an artifact that will be used to identify the oil stains of the fire, and this picture is a three-view of the artifact that describes it in detail." ”

Immediately, seeing that An Qian and the two tigers were still puzzled, Xie Xiuqi explained to them in detail what is the three perspectives of the main view, the top view, and the left view, supplemented by the dissection to accurately describe the three views of the structure of things, and how to read it.

The eyes of the second tiger were already a little shining.

The drawing method of this picture is quite similar to that of the West, but it is unheard of, and it seems that any artifact can be displayed in fine detail on paper from the inside out...... The young master's graffiti is ingenious and ingenious!

He has changed...... Erhu looked at the graphics on the paper intently, and sighed in his heart.

Although he did not understand how the seemingly strange artifact outlined in this picture could be used to identify the oil stains on the fire ground. But invisibly, Erhu was also quite confident in him, and he completely believed An Qi's previous explanation of the young master's abnormality.

"Young master, the structure of this thing is not complicated, go to the city to find a few craftsmen, and you will definitely be able to make it without any difference."

Erhu thought about it and said excitedly.

Xie Xiuqi was immediately overjoyed: "Then what are you waiting for?" Without further ado, Erhu, you go to find an old craftsman to make this thing well, the sooner it is made, the sooner I can experiment with whether this thing is really useful! ”

"Oh yes, there are still some items needed for the experiment, and you remember to buy them back for Erhu."

Then, after thinking about it even more, he added a list of items to the paper, and finally commanded in a stack.

The second tiger bowed down to answer the order, but An Qian suddenly said urgently on the side: "What about me?" Master. ”

The little girl looked at the three views drawn by Xie Xiuqi with stars in her eyes, and gradually became a little eager to try.

Xie Xiuqi looked at the little girl dotingly and smiled: "You go home with me, I estimate that this thing will be ready at least tomorrow." If you follow the two tigers to do this, who will serve me? ”

He also pities the fragrance and cherishes the jade, and he can't bear to follow the two tigers all over the city, and he has to be instructed everywhere.

The little girl was stunned, but she also understood her young master's kindness, and saw that her eyes gradually turned red.

After a long time, I saw her bow her head: "Then young master, the little maid will go home with you." It's time for dinner just late, what would you like to eat? ”

She wiped her eyes and whispered.
