    It was another day of high-intensity work, and we returned to the department tired and smelling sour.

    "I can finally sleep." A Le stretched.

    "sleep?"

    "What's wrong? Is there anything else?"

    "It has just begun. A lot of physical evidence has been extracted from the scene, and the results must be obtained in the shortest possible time."

    "What?"

    "If it were normal, I would let you go to bed, but you have to help me tonight."

    "I x, you want to kill me, right?"

    "Congratulations, you are able to answer quickly. Go to the trace examination room."

    "Honestly, are you jealous because I publicly chased Ye Qian?" As soon as I sat down on my front feet, A Le followed me on the back.

    "The case can't be solved, I have no intention at all. Take it." I handed the log with the wire tied to it to A Le.

    ¡°Can there still be fingerprints on the wooden pile?¡±

    ¡°Fingerprints are only a small classification in traces. Today we will focus on analyzing the logs, wires, knots and woven bags extracted from the site.¡±

    "What meaning can be derived from these analyses?"

    While Ale was talking, I had already classified the four types of physical evidence and placed them on the trace inspection table.

    "Start with the logs first." I turned on the multi-band light source in the inspection room. This light source is conducive to observing some small traces.  A Le imitated me and put on the filter glasses and turned his head over.

    "According to Lao Xian's speculation, the log was most likely cut from a growing tree. If you want to know which tree the log came from, analyzing its trace characteristics is a necessary step."

    "Is it something like annual rings?" A Le searched his mind and came up with a term.

    "Grown rings are only one aspect. We classify the organizational characteristics of wood into five major categories in trace science."

    "Five major categories?"

    "Yes, they are the bark characteristics, wood ray characteristics, tube hole characteristics, pith characteristics and growth ring characteristics of trees. The bark characteristics are easy to understand and do not need to be elaborated.

    "Wood rays are the only ray-like traces on the log cross-section. Wood rays can be divided into several types according to the degree of recognition. Those that are very obvious within the naked eye's visual distance are called 'extremely wide wood rays', and those that are clear to obvious under the naked eye are called'  Broad wood rays' are called 'medium wood rays' that are easily visible to the naked eye, and are called 'fine wood rays' that are visible to the naked eye. The ones on our log belong to the 'wide wood rays'.

    "Then there are the pore characteristics. The pore characteristics of trees include wood conduits and resin canals. The presence or absence of wood conduits is the biggest difference between broadleaf trees and coniferous trees. Only broadleaf trees will have conduits, while coniferous trees often have resin canals.  Resin canals are special pores surrounded by secretory cells that can secrete resin. They can only be seen under a magnifying glass. Judging from this feature, this log was cut from a broad-leaved tree.

    "Once again, the characteristics of the pith. The pith is also the core of the tree. It is the primary woody part composed of the first annual ring. It is located in the center of the trunk and is surrounded by xylem. It is a soft parenchyma tissue. The shape of the pith of different tree species  They are different in size and size, which can be used as a reference for unified identification.

    ¡°Finally, there is the growth ring feature. As seen on the cross-section of a tree trunk, the concentric circles surrounding the pith are growth rings, which are the process of cell division formed by the tree, cell maturation of new xylem, and accumulation of mature xylem.  Formed, it represents the traces of tree growth, which can also be used as a basis for analysis and comparison.

    "The above are general characteristics. We can also use some independent characteristics of trees, such as discoloration characteristics, knot characteristics, wormhole characteristics, scar characteristics, etc." At this point, my throat was already a little dry, so I scratched  He took a sip from the water cup and said: "It's not like before, where deforestation is very serious. Nowadays, the country has a very strong awareness of environmental protection. Illegal logging is illegal. If the suspect has a criminal record in the Forestry Bureau, then we have  target. Even if he is not caught, the logging movement is so big, it is not impossible if a witness appears. With these characteristics of the trees, we can make a unified identification of the tree stumps from traces. As long as we can compare  With two or more characteristic points, the suspect is absolutely indefensible!"

    "You are so cruel." A Le gave me a very fair evaluation.

    After explaining the theory eloquently, the next step is to record the characteristics in detail.  As the saying goes, it is easier said than done. I could finish the theory in 10 minutes, but it took me nearly 10 hours to study and record it. I don¡¯t know how long it took, but the sound of cockcrow accompanied the sunrise.

      Ah Le, who had not slept for two days, fell asleep on the table at some point.

    There is less than an hour left before the agreed meeting time. Although the body is extremely exhausted, the spirit has not fallen down yet.

    The bell rang at 9 o'clock in the morning. I put away the experimental data and woke up the sleeping Ah Le. Feeling like I was stepping on cotton, I stumbled into the conference room.  (Remember the website address: www.hlnovel.com
