After leaving No. 7 Third Avenue, Feng Bujue did not immediately rush to the cemetery in the north of the town, but continued to move towards the address of the fourth recipient.

He is a very methodical person and does not disrupt his plans lightly.

According to the route he had set in advance, after delivering the ninth letter, it was the most reasonable and time-saving plan to go around the cemetery.

Therefore...... Although he couldn't get the third letter out at the moment, he was still prepared to stick to the same route and wait for more information to be collected......

…………

Ten minutes later, Fourth Avenue, 10. 】

Brother Jue stopped in front of a familiar house, walked through a familiar piece of turf, stood on a familiar porch, and knocked on a familiar door.

Bang Bang Bang –

"Open the door! Velocity! Feng Bujue shouted while patting.

Soon, there was a sound of familiar footsteps upstairs, the door was opened a crack, and in the shadows behind the door, a familiar voice sounded: "Who are you looking for?" ”

"Postman, deliver the letter." Feng Bujue replied to these two words in a very fast voice, and skillfully showed the documents, and then continued, "Do you accept it?" ”

"No...... No. 4 Fat Man uttered only one syllable.

Brother Jue interrupted the other party rudely: "How many digits is your instruction code?" ”

"Uh......" the other party hesitated for half a second, and replied, "Four...... Four-digit ......"

"Is the first one one?" On the way here, Feng Buju had an idea, he wanted to use the characteristics of these recipients to "answer all questions", and rely on a set of targeted questioning methods to set out the specific values of the instruction code.

Pity...... This kind of behavior will naturally not succeed...... The system wouldn't allow such untechnical flattery.

"I can't answer that question." The tone in which the fat man said this sentence was indeed a bit of a game NPC.

"Oh......" Feng Bujue was not too surprised, because he also knew that this method would fail nine times out of ten, he just asked with the attitude of giving it a try, "That's ...... Is this number bigger than 5555 or smaller than 5555? ”

"I can't answer that question." Fat Man Number Four repeated the same answer in the same tone and voice as before.

"Is this an odd or even number? Is it a prime number? Is it a lucky number? Feng Bujue asked three more questions in one breath.

"I can't answer any of these questions." Fat man number four said he had no comment.

"Okay." Feng Bu was calm and at this point he could be sure that the recipients could only reveal the "type" (number, not letter or other) and "number of digits" of the instruction code.

"Is there anything else you can do? It's okay, just hurry up. Two seconds later, Fat Man No. 4 couldn't wait to give the eviction order.

"Before leaving, I want to ask by the way......" Brother Jue once again used the method of dealing with the second fat man, preventing the other party from slamming the door shut, and continued, "Are you a clone?" ”

"What are you talking about? I don't understand. Fat Man No. 4 replied.

"Oh?" Feng Bujue's eyes moved slightly, and he secretly said in his heart: "It's not that I can't answer this time...... But I don't understand......"

"If you don't know the code, I won't accept it, please reply." Five seconds later, the fat man No. 4 saw that the door could not be closed, so he simply put down this sentence and turned to go upstairs.

This time, Brother Jue didn't try to break in again. He just walked back on his bike and headed for the fifth address.

"Hmm...... Pretty much understood. He quickened the pace of pedaling and the pace of thinking, "The responses of these recipients to the questions were...... 'can answer,' 'can't answer,' and 'can't understand or give feedback.'" "Judging from the results of the trial, the information that can be answered is the most basic clue to solve the puzzle that I urgently need at the moment; Some temptations that are too direct or opportunistic about the answer to the riddle are classified as 'unanswerable', and 'incomprehensible or unanswerable' indicate ...... Scripted, these NPCs are unable to provide clues and answers to the corresponding questions. ”

When he thought of this, his expression became solemn: "Things are more complicated than I imagined...... In short, it is better to try again after going to the next address and confirm it. ”

…………

To cut a long story short, by 11:30 a.m., Feng had run out of addresses for the first nine letters.

Except for the first and second recipients, none of the recipients of the third to ninth letters received the letters.

However, Jue Ge still managed to confirm his previous inferences from them, and asked for the number of bits of their instruction code one by one.

Starting with the one on Third Avenue and ending with the "Fat Man Nine" on Ninth Street, the instruction codes for these seven people are: three digits, four digits, five digits, six digits, seven digits, eight digits and ten digits.

“OK…… It's almost time to get in touch with my 'ghost' colleague. After leaving the room at 3rd Ninth Street, Feng jumped on his bicycle and looked up, "According to the map...... On the way to the cemetery, you will pass by a shop, where you should be able to get the paper you need to send your letters......"

Along the way, he has found out the details of writing letters to ghost postmen: letters sent to ghost postmen do not need envelopes and stamps, as long as they follow the correct format of the letter and write the contents directly on a blank piece of paper. However, the paper on which the letter is written must be clean, the writing must be neat, and the wording must be polite and precise.

Of course, even if the sender strictly followed these requirements...... Will the ghost postman reply to the letter after receiving it, and how often...... Also unknown.

"Anyway, I ......already have a pen to write letters," Feng Bujue read as he rode his bicycle, "If the store is open, I can still buy some food and drink by the way, and replenish my ability." Even if it's not open normally, it shouldn't be difficult to get a piece of paper or something......"

Just as Brother Jue was thinking, he suddenly ......

Whoop Boom Boom Boom ...... The familiar voice came from the fog again.

"Coming back?" Brother Jue's eyes quickly caught the tire marks on the ground, and he knew that his "colleague" was going to pass by again.

"Alas...... Brother will make way for you. Feng Bujue said a word silently in his heart, turned the head of the car, and rode to the side of the road.

He thought that the ghost postman would pass by silently as he did when he first met him, but unexpectedly, he didn't expect it to ......

Whew-

With the sound of a breaking wind, a roll of newspaper suddenly appeared in mid-air and landed accurately in Jue's bicycle pocket.

Judging by the trajectory of the newspaper...... It seems that the ghost postman threw it when he passed by Brother Jue. R1152
