The name of the video publisher is Caigou.

The video starts playing.

The picture is a first-person perspective, with a courier box on the other party's table, and he uses a fruit knife to cut open the seal and open the box.

The camera continues to move forward, shining into the delivery box.

There's something extremely weird in there.

It's like a group of earthworms entangled together, hundreds of meat worms wriggle in various ways, and people who watch it are physically uncomfortable.

"Damn, what the hell, disgusting."

The other party hurriedly covered the courier.

The video came to an abrupt end.

A quote from the publisher of the video is attached.

Caigou: [I'm scared to death, you must be cautious when opening the express, there may be something inside.] I resealed the box and set it in the hallway and set it on fire. ]

The video sparked a heated discussion among the player base.

There had been speculation that the delivery box was dangerous, but now it has been confirmed, further causing panic about the delivery box itself.

Many people say that they will not easily unpack the express, or that more people get together to unpack the express and help each other.

It's not uncommon to get gangs in games.

Acting alone and as a team has its own benefits.

Chen Bei looked at the group chat, and then looked at his two express boxes, thoughtfully.

After a while, Leo made progress and sent new news.

Leo: [I got the courier back!] ]

After that, the other party described his experience of picking up the parcel and also shared an important piece of information.

The entire dormitory building is topped out on five floors.

Downstairs is a large courtyard with two courtyard gates, the main entrance is a security booth, and the back door has a courier cabinet.

Outside the door is foggy and mysterious.

Couriers walked in and out of the fog one after another.

At the door of the security booth, a security guard duty announcement was hung.

There is important information on it, Leo took a photo and sent it directly to Chenbei.

It reads as follows.

——

There are a total of four security guards on duty in the security booth in turn.

The names of the security guards were: □ Yi, □□, Sun □, and □ Si.

The day is divided into four time periods, and each shift lasts 6 hours.

The rotation schedule for the four shifts is as follows:

0 to 6 o'clock, morning shift.

6 a.m. to 11:50 a.m., middle class.

12 o'clock to 18 o'clock, evening shift.

18:10 to 0:00, night shift.

Please note the following information.

A security guard is keen to patrol.

A security guard has a bad temper, but his surname is liked by everyone.

A security guard only lets acquaintances pick up couriers.

A security guard likes to guess riddles, and only when he answers correctly will the player be allowed to pick up the delivery. With a riddle, you can guess his last name, and the riddle is: No traffic.

——

Chenbei carefully watched it from beginning to end.

Four of the names of the security guards, □ representing the smeared parts, are hidden.

Obviously.

It is necessary to use known information to derive hidden information.

This is the classic "conditional reasoning".

Leo: [This content is for players to reason about the specific situation of the security guard, and then make a judgment to pick up the delivery in the right way.] If you don't use your brain, it's dangerous, and you might even risk your life. I've cracked this content, it's actually quite simple, think about it for yourself first. If you don't understand, ask me again. ]

Degree Zero: [Okay.] ]

Anyway, there is no courier to come to the door now, it is free time.

Chenbei patiently studied this security information.

At first glance, it looks like a cloud.

When you think about it, it suddenly dawns.

The first is the name of the security guard.

□ 1, □□, Sun □, □ 4.

Only the surname "Sun" is clear, the remaining three are hidden.

The name has one or four numbers, which proves that it is a numerical order.

Sun is in third place, and this is another surname.

An answer is on the horizon.

Hundred family names!

Zhao Qian, Sun Li.

One two three four.

That's the name of the security guard, and it's easy to remember.

Shifts are divided into four time slots.

The last three of these time periods are special.

The middle shift leaves 10 minutes early.

The night shift arrived 10 minutes late.

One leaves early, one arrives late.

It's as if they're all hiding from the security guard caught in the middle.

So the third shift, that is, the security guard on the night shift, he should be the one with the worst temper.

This bad-tempered security guard, his surname is loved by everyone.

That can only be money!

It can be seen from this.

Morning shift?

Lunch shift?

The night shift, Qian Er, has the worst temper and represents danger.

Graveyard shift?

Continue reasoning.

The security guard who likes to guess riddles, the last name riddle is: no traffic.

Zhao Qian, Sun Li four surnames.

Among them, the surname "Zhao" is disassembled, which is to add a piece to the side, corresponding to the meaning of prohibiting traffic.

So it's the security guard Zhao Yi who likes to guess riddles.

There are two security guards left, and one only allows acquaintances to pick up the delivery.

So what counts as an acquaintance?

Since they are acquaintances, they will definitely be able to say the name of the security guard!

Exclude two options.

Then this security guard is one of Sun San or Li Si.

Choose one of the two, even if you use Meng, there is half a chance.

Tatsubei gave his reasoning to Leo and was affirmed.

The latter also made a little addition.

Leo: [I just picked up the courier and found that there was no one in the security booth, only the courier on the shelf.] This proved that the security patrol went, so I took my own delivery and went home safely. ]

Degree Zero: [That would be clearer.] The morning shift security guard loves to patrol, the afternoon shift is uncertain, and the night shift security guard is grumpy and the night shift is uncertain. These two uncertain time periods correspond to the two key points of acquaintances and riddles. ]

Leo: [BingO!] In other words, three time periods of the four-shift post are relatively safe, as long as you make good use of the characteristics of security. Only the grumpy security guard in the third shift, it's best not to provoke it. ]

Degree Zero: [There's another important point.] Since such a large set of twists and turns of additional content has been set up for the security guards, it proves that the existence of the security guards is biased towards rule killing. If you can take out the security guards by pure force, then this set of things is completely meaningless. ]

Leo: [Yes!] If you want to solve the game by force, you can start with the courier, but don't attack the security guards. ]

Zero: [You went to the security booth just now and saw a few deliveries?] ]

Leo: [There are several!] ]

Degree Zero: [You only took one?] ]

Leo: [Well, just one, because I wasn't sure if there were any hidden risks in taking someone else's delivery, so I didn't mess around.] Seven days of playtime, with a minimum of 10 delivery boxes. In fact, you only need to take one to three couriers a day. ]

Zero: [But my goal is to be in the top three.] ]

Leo: [I'll try to help you achieve your goals, but don't be rash just yet, at least make the game clear.] ]

Zero: [Yes, there are only two of the three ways to receive express delivery, and we have not tried one yet.] ]

Say what you say, come out of what.

Not long after that, Zero received a new pickup notice.

[Pickup Notice: Your courier has been stored in the courier locker, please select the correct cabinet to take out the courier according to the pickup code 1245. 】

[Warning: You must pick up the parcel as soon as possible, if you occupy the locker for a long time, your game currency will be deducted according to the timeout rule.] If there is not enough in-game currency, it will become a liability. 】
