Qi Ji opened another pack of napkins, and this time the pattern was completely different from the one he opened in the previous pack.

This time, the pattern that can be seen on this napkin is two baby birds and a huge black bird beast, and there is a number 5 on the back.

Qi Ji found another similar pattern in the same pack of napkins.

But the difference is that the pattern on this napkin is three baby birds and a black bird beast, and the number on the back of the napkin is 6.

Qi Ji quickly figured out through mental arithmetic that the baby bird represented the number 1, and the black bird represented the number 3.

The fat man, the blonde girl, and the short-haired girl all had question marks on their faces. The three of them had no idea what Qi Ji was doing.

The three were surprised to find that they were almost useless and could only do some menial work. They were all awkward for a while.

Next, Qi Ji opened several more packs of napkins, which also had repeating patterns.

He had already calculated the repeating patterns, so he simply chose to skip them.

After a while, Qi Ji found another napkin with a different pattern.

When he unwrapped the napkin and spread it out outside the window, he was surprised to find that there were exactly four patterns this time.

He looked at the napkin carefully and found four different kinds of flowers on it.

The floral patterns are very delicate and although small, they look very realistic.

Qi Ji was surprised to find that he didn't recognize these flowers, but he didn't take the initiative to use his talent to explore them.

This time, Qi Ji saw that the number on the back of the napkin was 3!

"What's going on? There are clearly four flowers, why is the number 3?" Qi Ji frowned.

He thought about it and then turned his attention to the patterns of the flowers.

This time he discovered that one of the four flowers was withered. The entire flower had withered to the point that only the branches and some scattered leaves were left.

Qi Ji quickly guessed that the flower represented the number 0.

Because the withered flower is dead, in a sense death represents the number zero.

In order to prove his guess, Qi Ji took out another slightly different napkin from the pack.

This time, only the three vibrant floral patterns were drawn, and there was a number 3 on the back of the napkin.

Qi Ji pulled out a few more sanitary napkins and found that the remaining ones were duplicates of these two.

Then the remaining three flowers all represent the number 1, so the 8-digit password is complete.

But there is still an important question, which is in what order the password should be entered. Qi Ji thought.

Qi Ji picked up several napkin bags that he had opened earlier and began to observe them. It didn't take long before he thought of an important clue.

That’s the production date of the napkin!

Qi Ji's eyes suddenly lit up, and he checked the production dates of these four types of napkin bags.

And as expected, the production dates of these four types of napkin bags were different.

"Among them, the one with the bird and animal pattern was produced the earliest, in January this year; the one with the butterfly and caterpillar pattern was produced the second earliest, in March this year; and the last four kinds of flowers were produced in May this year."

"Now we can form a three-part password, but we still need to sort the order of the three parts of the password..."

After a brief thought, Qi Ji's eyes lit up, and he said confidently, "A chick grows up and becomes a bird or beast, a caterpillar turns into a cocoon and finally turns into a butterfly. The first four digits of the password should be 1353, and the last four digits, if I'm right, should be 1110."

"Three flowers represent the number 1, and the withering of the flowers means the end, and the number 0 is placed at the end. So the final password should be 13531110!"

After hearing Qi Ji's explanation, the three of them opened their mouths wide.

"Damn it! Brother Qi, do you have to be so perverted? You can even think of this!" Niu Wu said in shock.

The blonde girl and the short-haired girl also looked horrified. They had never thought that the napkin placed casually on the folding table could be the clue to pass the level.

What’s more important is that they found that Qi Ji’s operation was continuous and it was simply amazing.

"If my guess is correct, the three flowers that haven't withered should represent different seasons. The three-digit code should be arranged in the order of the blooming seasons. However, if these three flowers all represent the number one, this step can be ignored." said the blonde girl.

After hearing this, Qi Ji nodded approvingly. He had thought of this.

The key is that he doesn't recognize any of these three flowers, so he is too lazy to go through the extra verification steps.

"Let's go!"

Qi Ji was the first to come to the password door and entered the eight numbers. Not long after, the heavy metal door opened automatically.

Seeing the metal door open automatically, the three people looked at Qi Ji with deep admiration in their eyes.

Qi Ji smiled slightly and went straight into the sixth carriage.

When the four people entered the sixth carriage, they all felt that the carriage was very hot.

"Damn, why is it so hot? The temperature should be almost 40 degrees. What's going on?" the fat man said speechlessly.

Sweat also began to appear on the foreheads of the blonde girl and the short-haired girl. It was obvious that they were not used to this high temperature environment.

"Welcome to the sixth carriage. This will be the end of your game. Pass this level and the test will be over."

At this moment, the same hoarse and heavy male voice suddenly rang in everyone's ears. After hearing this, the nerves of the four people couldn't help but tense up.

"To pass the level, do whatever it takes to escape and enter the final carriage! Warm reminder: The current temperature is 38 degrees, increasing by 2 degrees per minute. The time limit for passing the level is 8 minutes. The less time you take, the higher the score!"

…

"Boss, we have to rely on you this time! We don't ask for any extra points, as long as we don't get deducted!" said the short-haired girl.

The blonde girl nodded in approval, because after going through these levels, she helplessly discovered that she had no clue at all in such a short time.

Maybe you can give yourself more time and solve the puzzles in the car, but each level has a time limit!

So the blonde girl simply hugged the thigh. Although her score might not be high in the end, she was undoubtedly extremely lucky.

Because if she hadn't met the big boss, she felt that she would be in a terrible state. Whenever she thought about the points deducted after failing a level, she couldn't help but tremble all over.

"Brother Qi, I have to rely on you. After we go out this time, you will be my boss Niu Wu! From now on, I will be at your disposal." The fat man said with a smile on his fat face.

Qi Ji was speechless when he saw the people in front of him behaving like elementary school students.

"How do you know I can definitely pass this level!"

"Boss, I believe in you! If you can't pass it, no one else can." The blonde girl said firmly.

"Brother Qi, you are the most awesome person I have ever met, no doubt about it! I believe in you!" Niu Wu said with admiration on his face.

…

Qi Ji shook his head helplessly, not intending to pay too much attention to it, and just looked around the carriage.

He found that the top of his head was covered with sunlamps, which were very bright, which was why the temperature in the room was so high.

Qi Ji's eyes quickly locked onto several constantly rotating gears in a large groove not far to the front left, which drove their respective rods to move together.

After looking carefully for a while, Qi Ji discovered that the mechanism was missing a part.

At this moment, a prompt suddenly appeared in his mind, proving this point.

[There is a gear missing in this mechanism. If you add this gear, the whole mechanism can achieve true full movement, thus driving the door of this level's carriage to open. Note: This mechanism controls the opening and closing of these two doors at the same time, so this level is not as simple as you think.]
