Luo Dongyan told Zhang Wenxi in a low voice, and both of them turned their inquiring eyes to Qin Lin.

Qin Lin smiled and said matter-of-factly: "Actually, there are many other things left on the hemp rope that Zhang Xun saw just now, but this microscope is too small, and you can't see it clearly." ”

So what to do? Zhang Wenxi's face was full of embarrassment, the microscope he saw today was already a miracle of knowledge in his mind, and he couldn't even see it with a microscope, did he have to open his eyes to heaven?

Qin Lin was not in a hurry to answer, he glanced at the cow vigorously, and the old cow took out a thick and long thing from the package he was carrying, and ripped off the cloth cover outside, which turned out to be a brass tube with a thick end and a thin end and a length of two feet, the thick end was about the same as the mouth of the bowl, and the thin end was about an inch in diameter, and both ends were inlaid with lenses.

Zhang Wenxi was surprised and delighted: "This, this, dare to ask Qin Shaobao, that was a microscope just now, what is this?" ”

"High magnification microscope!" Qin Lin replied solemnly.

Poof~~ Zhang Wenxi and Luo Dongyan were absolutely overwhelmed, and they couldn't imagine that they would get such an answer if they wanted to break their heads, Lu Yuanzhi and Niu Dali also looked at each other, and Chief Qin urged the ability to play tricks on people, there is really nothing to say.

Zhang Wenxi couldn't help laughing, his face flushed, and he arched his hand at Qin Lin: "So, is Qin Shaobao's 'high-powered microscope' also used like just now?" ”

"Almost," Qin Lin replied nonchalantly.

The weight of the high-powered microscope is relatively large, and it is inconvenient to hold it in the hand, so there is an additional folding bracket with a hollow tray, and Niu vigorously takes out the bracket and installs the lens barrel.

Qin Lin put the hemp rope on the tray and made a gesture of invitation to Zhang Wenxi.

This time, the hemp rope in Zhang Wenxi's field of vision is ten times larger than just now, if the thickness of the hemp rope fibers seen just now is about the same as the little thumb, then this time those fibers look like thighs, and the granular things attached to them also show the outline, and with the focus adjustment in place, it is even more clear that they are some small brown and yellow grains.

Zhang Wenxi was overjoyed when he saw Hunting, and while following Qin Lin's instructions, he asked: "Qin Shaobao, what the lower officials saw seems to be a little distorted and deformed?" But it's still clear. Hey, what are these little particles? ”

The lens grinding technology of this era, of course, can not be compared with the optical industry of later generations, Qin Lin used Western concave and convex lenses to make a high-power microscope, a slight distortion is inevitable, fortunately he can use a large aperture lens barrel to make up for this shortcoming, whether it is a microscope or a telescope, the larger the aperture always has an advantage.

"Those particles, floating in the air, moving with the wind, diffuse everywhere, sticking to our clothes, entering our bodies with breathing, everywhere......" Qin Lin paused and gave the final answer: "That's pollen." ”

Pollen particles are very fine, can float in the air for a long time, it gathers on the stamens of flowers and can be seen with the naked eye, but floating in the air, it can not be detected by the naked eye, so few people notice that in the air they usually breathe, there are actually a lot of unclear pollen, especially in the spring when the flowers are in full bloom, too much pollen in the air can also cause spring ringworm and pollen allergies.

In clear weather, pollen flutters in the wind, gets to people's skin, attaches to clothing, and even sucks people into their lungs, so after a case occurs, you can help solve the case by identifying the pollen.

Not only was there a lot of pollen on the hemp rope of this string of copper coins, but Qin Lin also found the same kind of pollen on other newer hemp ropes, which shows that there are a large number of such plants in the place where the private miners secretly minted copper coins. As long as you identify what kind of plant the pollen on the hemp rope belongs to, it is very likely that you will quickly find it.

For example, if you find out that the hemp rope is camellia pollen, you just have to look for it in the place where a large area of camellia grows in Longyou County.

Hearing Qin Lin's words, Zhang Wenxi and Luo Dongyan were suddenly shocked, looked at each other, and had a look of horror on their faces - even on the "Collection of Grievances", there is no such subtle means as Qin Lin.

"No wonder, no wonder Qin Shaobao ordered the official schools to collect flowers everywhere, it turned out that this was for this! It's really unpredictable! Zhang Wenxi suddenly realized, and praised it repeatedly.

Hehe, Qin Lin laughed dryly, and his old face was slightly red.

If he was a botanist, or if he had a pollen illustrated book at hand, he would have done this a long time ago, but unfortunately he was a forensic doctor and a master of criminal investigation, but he didn't know much about botany, at least he couldn't know what kind of plant it was by looking at the pollen, so he had to ask the brothers in the official school to collect flowers everywhere and bring them back for comparison and examination.

The scattered officials came back one after another, bringing back all kinds of flowers, all of which were placed in the second hall of the county government, and the fragrance of purple and red flowers in the room was intoxicating for a while.

It's a pity that Qin Lin didn't have time to enjoy the gorgeous flowers, so he carried out the comparison and identification work intensively, lying in front of the high-powered microscope to check the pollen of various flowers.

Different kinds of plants have their own pollen, birch pollen resembles blue wet dough, lily pollen is in the shape of earthy yellow beans, and dandelion pollen is small bright yellow balls...... The work was carried out in a tense and orderly manner, and the eyes were sore and unbearable after watching this work for a long time, but fortunately, there was only a high-powered microscope, and the comparison work was very simple and did not require any professional knowledge, so Qin Lin, Lu Yuanzhi, and Niu Dali took turns to fight, and they refused to stop if they did not find out what kind of plant the pollen stained on the hemp rope belonged to.

During their working hours, the other two officials were not idle:

Zhang Wenxi, as the imperial governor of Zhejiang, wrote the official documents sent to the surrounding prefectures and counties, the orders for the mobilization of the officers and soldiers of the guards, and the submission to the imperial court; Luo Dongyan secretly mobilized a few experienced veterans in Longyou County to recruit people from ten miles and eight townships, and prepared to wait for the results of the comparison to come out, and through these people who were familiar with the local situation, they would work together to find the hiding place of the private casters.

But from noon to night, the three Qin Lin, who were busy in the second hall, had not yet come to a clear conclusion.

Luo Dongyan couldn't help but tug at Zhang Wenxi, and said in a low voice: "Brother Zhang Nian, what do you think of Qin Shaobao? ”

"In the same year, Qin Shaobao's knowledge of learning has been perfected, what else can you not believe?" Zhang Wenxi frowned, stopped Luo Dongyan, and walked into the second hall again: "I don't know what difficulties Qin Shaobao has?" Lower officials may be able to work a little. ”

Qin Lin, who was looking at the microscope, turned around and startled Zhang Wenxi, only to see that Qin Lin's eyes were red, his eyes were bloodshot, and a tear was sliding down his cheek.

"I haven't found it yet," Qin Lin rubbed his red eyes, dipped a white towel in cold water, and scratched his scalp: "This thing is a bit weird......

From noon to evening, at this time, the second hall lit a big candle and shone like day, and Lu Yuanzhi took over from Qin Lin to continue the comparison work.

The pollen of hundreds of plants has been compared, and no one has been found to be exactly the same as the one stained on the hemp rope, which makes Qin Lin wonder.

According to it, pollen can be stained on the hemp rope in large quantities, which means that this plant appears in patches, with a considerable scale, and the official schools sent out to sample will not be invisible, but in fact, the official schools have even taken some relatively rare rare plants, but there is no such pollen.

Could it be that there is a mistake in the direction of detection?

Qin Lin sorted out the relevant situation in his heart, and in the Wufeng Maritime Warehouse, through weighing and analysis, it was determined that the private coins with insufficient copper content came from Quzhou, and Longyou belonged to Quzhou; Before his death, the shopkeeper Du hinted that there was something unusual in Longyou County, and it was very unusual that he did not carry out the purchase of copper coins as soon as possible; The private coins obtained from the pillow box of the Du shopkeeper, as well as the newer private coins collected on the market, and the hemp rope used to string the money are all produced in Longyou County...... All kinds of facts are definitely not coincidences, and there is nothing wrong with the direction of detection!

Perhaps, the lieutenants missed a sample collection?

Qin Lin called the officials and schools to ask, did they miss some tall trees, or ignored some low shrubs or grasses?

The officials and schools all said that they collected very carefully, and every kind of flowers and trees, as long as they bloomed, were brought.

Qin Lin thought about it, there are even some rare flowers and plants here, there should be no omission, not to mention that many hemp ropes are contaminated with the same kind of pollen, which means that this plant appears in patches and blooms in large quantities, and the officials and schools in Jinyi will not notice it.

Aha~~ Qin Lin yawned: "Sleep first, and then go out to check at dawn, now the mountains and rivers are exhausted and there is no way out, maybe tomorrow there will be another village." ”——

On the other side of the Qujiang River, in the bamboo forest where the bamboo forest temple has become yellow, a white figure stands on the tip of the highest bamboo, white clothes like snow, posture like a fairy, the breeze blows slowly, the bamboo shakes gently, her toes tap the bamboo slightly, the body moves with a certain magical rhythm, and the breeze and the bamboo forest are integrated.

The slight sound of footsteps on the withered yellow bamboo leaves on the ground alarmed the White Lotus Sect Master, and her eyes hidden behind the silver mask suddenly opened: "Who is it?" ”

"Subordinates, knock on the Divine Merit, Shengde, Bright and Great Sage Sect Master!" A bald old monk, holding a food box in his hand, if it is the people of Longyou County, they must know this foolish bamboo abbot of the Bamboo Forest Zen Temple, but he does not worship the Buddha and Guanyin now, but worships the White Lotus Sect Master as a disciple.

"My subordinates inquired and learned that the Qin Demon Leader ordered Ti to ride out and collect all kinds of flowers for him, I don't know what the hell is going on," the abbot of Yuzhu paused, and said with sincere fear: "This place was originally a green bamboo forest, which is very suitable for the Holy Sect Master to cultivate divine skills, alas, it's a pity...... However, his subordinates were also able to prepare this bowl of bamboo rice and eight treasure rice, and worship it here, wishing the Holy Sect Master Feng his body and health. ”

Legend has it that the phoenix "does not inhabit the sycamore, does not eat the bamboo", this bamboo rice is the food of the phoenix, which is precious and rare.

The White Lotus Sect Master nodded indispensably, Yuzhu put down the food and turned to walk away, the White Lotus Sect Master stretched out his hand and made a move, and the food box flew into her hand in the air, opened the lid of the box and tasted it, only to feel that the taste was sweet and sour.

"This kind of thing, Asha should like it very much, right?" The White Lotus Sect Leader thought about it while eating, and was puzzled: Qin Lin, what are you going to do when you collect flowers
