"What did you say?" Feng Bujue's attitude was firm. "Let me take it apart?" He snorted. "Are you sick? What if it explodes?"

The homeowner was shocked. "Hey... you're the one who said, 'It's just a letter, not a bomb'..."

"What I say is what it is? Then I also said to accept the letter, would you listen?" Feng Bujue interrupted sharply. "Enough nonsense, hurry up and take it. I still have a dozen or so letters to deliver. I'm very busy."

"No... I refuse." Although the homeowner refused, he didn't slam the door again, nor did he try to drive Brother Jue away. After hesitating for a few seconds, he said, "If you insist on me accepting this letter, recite my 'instruction code'..."

"What code?" Feng Bujue asked suspiciously.

"Instruction code," the homeowner repeated.

"What is that thing?" Brother Jue asked again.

"You don't know? Heh heh heh..." The homeowner suddenly laughed. "Then I'm sorry, I can't..."

"Wait," Feng Bujue interrupted him again. "As long as you say the 'instruction code', you... have to accept this letter, right?"

The homeowner swallowed nervously. "If you can say it... I'll take the letter."

"Oh..." Feng Bujue nodded, and then began to bluff, "When I left, the chief told me a lot of instruction codes, and I'm a little confused..." He squinted at the other party and tentatively asked, "Is your code... a number or English?"

"All instruction codes are numbers," the homeowner replied quickly, but after the words came out, he paused. "Eh? Have they introduced English codes now?"

"Yeah." One of Feng Bujue's great skills was talking nonsense with a straight face. "There are also mixed English and number codes." He paused. "Oh... right, how many digits is your code?"

"Uh... one digit..." the homeowner replied in a low voice.

"One digit?" Feng Bujue looked at the shadow behind the door with a "are you kidding me?" expression, remained silent for a moment, and then asked in a questioning tone, "Um... one?"

"Damn..." The homeowner muttered angrily after hearing the number, reached out and took the letter, and then... closed the door.

[Side quest progress updated] The system voice also sounded at this moment.

"What the hell?" Feng Bujue looked at the door panel, stunned. "What kind of plane... what kind of dong dong... what kind of code? Isn't it just a one? One digit... I could have guessed it in ten tries at most! Are you sick!"

He cursed at the door panel a few times before turning to leave. As he crossed the front yard, he glanced at the game menu and confirmed that the task progress had changed to [Deliver all letters before midnight, current progress 1/13].

"But... come to think of it..." Brother Jue returned to his bicycle and muttered softly, "This guy's behavior is very abnormal, and it doesn't seem to be an intelligence problem..." His gaze instinctively shifted to the temporary work permit in his hand. "After learning my identity, his attitude changed significantly. Although he didn't seem willing, he still answered all the questions I asked..." As he spoke, he put the work permit back into the inside pocket of his jacket. "It seems... this thing is much more useful than I thought..."

…………

Long if there is a book, short if there isn't.

Ten minutes later, Brother Jue arrived at the second delivery address in order: [Second Avenue, Number Nine.]

"Um... at this speed, even if I go to places other than the delivery addresses to do some investigation, there will be plenty of time." Feng Bujue thought to himself as he parked his bicycle, "It's ten o'clock in the morning now, and I have twelve letters in hand. Even if I deliver one every half hour on average, I can finish delivering them before four o'clock in the afternoon, and there will be more than enough time to take a lunch break in between..."

While thinking, he walked towards the door of a house.

The style of this house was almost the same as the one at Number Three, First Avenue, except that the color of the outer wall of the house was slightly different.

And this house also had no mailbox in front of the door, and its front yard was also overgrown with weeds.

Pa pa pa—

"Is anyone home?" Feng Bujue also used the same knocking method as before.

After a brief silence, there was some movement from the second floor of the house, followed by... the sound of a fat man walking downstairs in slippers.

Ka—

A moment later, the door opened, still only a crack.

The inside of the house was dark, and the second homeowner was also standing in the darkness, asking weakly, "Who are you looking for?"

This scene gave Feng Bujue a very strong sense of déjà vu, and he couldn't help but think, "What's going on? Even the voice is the same? Twins?"

"Who are you looking for?" The homeowner asked again when he saw that Brother Jue didn't answer.

Feng Bujue thought for half a second, and directly showed his ID. "Mailman." After saying that, he handed over the envelope. "Delivering a letter."

The concise sentences made the homeowner gasp. "You... this..." He muttered a few words hesitantly, and after a long time, he squeezed out a complete word: "I don't want it! Take it away!"

"Hmph... don't want it?" Feng Bujue sneered. "Do I have to recite your instruction code before you accept it?"

His tone was as if he really knew it...

"You... you say..." The homeowner seemed to still have a glimmer of hope and refused to give in.

"Two?" Feng Bujue asked tentatively.

"Hahahaha..." Suddenly, the homeowner laughed. "Wrong!"

"Three?" Feng Bujue tried another one, anyway, it didn't cost anything to try...

"Wrong..." the homeowner replied again.

"Four?" Brother Jue continued nonchalantly.

"Wrong!" The homeowner raised his voice, interrupting. "Are you planning to recite them one by one?"

"That's right," Feng Bujue replied. "Is that not allowed?"

"Uh..." The homeowner thought for a while. "Allowed..." He gave an affirmative answer.

"Oh, right..." Feng Bujue thought of something else. He continued, "Your instruction code should also be a single digit, right?"

"It's two digits," the other party replied.

"Huh?" Feng Bujue was stunned, and immediately thought to himself, "Hey hey... this doesn't seem good, I thought they were all single digits... but the second guy is two digits... then what if there are seven or eight digits later, even if I have the patience to try them one by one, there won't be enough time..."

"You... can go back now, right?" The homeowner asked without confidence.

Feng Bujue's response was: "Um hum..." He cleared his throat and chuckled. "Heh... eleven?"
