"It seems that this is a new letter to us from the 'actors'!" After reciting the above words silently, Wu Wenhui looked up at Fang Lubai.

Fang Lubai smiled bitterly, his face showed a look of agreement, and then Wu Wenhui turned his gaze to the suppressed letter again.

"This one is also in an envelope? How does it not feel like it was written by the same person? Wu Wenhui looked at the piece of paper and asked Fang Lubai with some uncertainty.

"That's what I just imitated." Lu Zhu replied to Wu Wenhui in a low voice, but his eyes never took his eyes off Fang Lubai's body.

"That's right, this is what I just asked Lu Zhu to imitate, what did you find?" Fang Lubai touched his chin and stared at the two pieces of paper.

Wu Wenhui looked at the two handwritings carefully, and then asked uncertainly: "Do you think the other party is a left-hander?"

"That's right!" Fang Lubai snapped his fingers, and then turned the two pieces of paper in Wu Wenhui's hand to the back: "You see, Lu Zhu has always been left-handed, which is what we all know, so I won't say more."

"How can you tell from my handwriting that the other person is left-handed?" Lu Zhu muttered quietly.

"That's a good question." After Fang Lubai finished speaking, he spread the two pieces of paper together, and then asked Lu Zhu: "Do you usually use your left hand or your right hand?"

Lu Zhu thought for a moment, and then said, "I am usually used to writing with both hands."

"Then why did you just write with your left hand?" Fang Lubai asked a little slyly.

"Purely for convenience." Lu Zhu said without thinking.

"Here, write again with your right hand." Fang Lubai stretched out his hand and tore down a piece of paper and handed it to Lu Zhu. Lu Zhu had no worries in his heart, so he wrote quickly.

Did you see anything? Fang Lubai put two pieces of paper in front of him and asked softly.

"It seems... It seems a little awkward. Lu Zhu also carefully observed his handwriting for the first time, and after thinking for a while, he still said his opinion.

"That's right, it's awkward." Fang Lubai clapped his hands, and then explained the mystery to everyone. "Lu Zhu usually writes with his right hand, but occasionally writes and draws with his left hand, am I right?" Fang Lubai looked up at Lu Zhu and found that he was concentrating on the handwriting in front of him, he simply lowered his head and continued: "According to my observation during this period of time, Lu Zhu should have been a left-handed person before, but for some reason, he turned his hand holding the pen to his right hand, which should have changed his writing method because he was thinking that there was a gap between his own writing and others."

Seeing that Lu Zhu was still silent, Fang Lubai continued: "The most significant feature of forcibly changing the hand holding the pen in this way is that the strength of the writing is not easy to control, but fortunately, Lu Zhu usually uses his right hand, so it is not so obvious, but look at this letter paper." Fang Lubai stretched out his hand and pointed at the back of the letter: "When these characters are written, the nib of the pen is particularly powerful, but the nib of the pen under the force does not puncture the paper, it should be something underneath." And you see here, the strokes in these places are not smooth, and they seem to have been deliberately controlled to achieve the effect, so it looks a little weird. Fang Lubai's fingertips touched the letter paper lightly, analyzing his judgment with everyone.

"This person should be worried that he was found to have a problem with the way he writes, so he changed to writing these words with his right hand, if he hadn't seen Lu Zhu's writing posture, I'm afraid this important clue would have been ignored." After Fang Lubai finished speaking, he looked up at Lu Zhu.

Only then did Lu Zhu realize that he had misunderstood Fang Lubai's intentions, and looked at those words with a flushed face, without looking at Fang Lubai.

"I want to cover up my own characteristics in this way, which proves that the other party is thoughtful and doesn't want to leave any flaws, but unfortunately, there will be a mistake in the hundred."

After finishing speaking, Fang Lubai straightened out his thoughts and said slowly: "Combined with the last analysis, the suspect's height is about 1.7 to 1.75 meters, his weight is 60 kilograms, he is used to being left-handed, he has a good education, it is not excluded that he has a college experience, he has a stable job in Tianhai City, but his income is not considerable, his favorite color is mainly black, and his clothes are basically cold colors.

After Fang Lubai finished saying these news in one breath, he found that everyone was looking at him with stunned eyes, Fang Lubai asked puzzledly: "It's all up to me, hurry up and move, there are only three days left!"

Only then did everyone come back to their senses and write down the analysis that Fang Lubai had just said in their notebooks. Fang Lubai took a sip of water, turned his head and asked Gu Na, "Have you found the address to send the letter?"

Gu Na stood up and put a picture in front of the secret recipe Lu Bai: "This is the address written on the envelope, but it has long been a demolition house, so the address should be a fake address: the mailbox where the letter was delivered is not far away, and the post office is being demolished, so no useful surveillance footage was found." Guna's hand lightly touched the table, and there was a clear sound on the table.

"There seems to be something in the envelope." Gu Na stood beside her, rubbing her arm with her left hand, and then said to Fang Lubai in some surprise.

"Anything else?" Fang Lubai put the picture aside in confusion and grabbed the already empty envelope with his hand.

It's not big, and it's a little hard to the touch. Fang Lubai gently tilted the opening, and a round coin slipped out of the envelope and spun around on the table.

"What is this?" Fang Lubai looked at the coin lying on the table, looked up and asked Gu Na, but the phone wiped it into his pocket.

Gu Na picked up the coin with a piece of paper, just glanced at it roughly, and then said to Fang Lubai: "I know, this is a game currency of a game machine, and many people call it 'lucky coin'"

"Lucky coins?" After Fang Lubai muttered a whisper, he took out another coin from his pocket, and two silver-white coins were placed on the table, glowing with a glimmer of light.

"It's just a very ordinary notebook coin, but there is only one place where this kind of coin can be used as a trading chip." After Gu Na finished speaking, she placed the laptop in front of Fang Lubai.

Her fingers tapped lightly on the screen, and she said slowly: "This is the largest entertainment venue in Tianhai City, and this coin is the universal currency in it."

"What's in this big entertainment venue?" After clicking on the marked place casually, he swiped the simple page with one hand, and carefully browsed the information on it.

Next to the building marked on the map, only some simple information was written, which seems to be some information that Guna found on the computer, and there is no record of more detailed content. Fang showed white eyes, but his eyes looked at the two coins on the table.
