"Good fellow, there's something there! Fang Yao, you're okay, I'm Zhu Shao! ”

With a look of admiration, Zhu Shao took out four rectangular stones about three centimeters long and two centimeters wide from the inside of these bears.

A number was deeply placed on each stone with a carving knife.

"I think it's the work of the mystery man, and these numbers are what the mystery man wants us to discover." The corners of Fang Yao's mouth finally hooked up the arc of victory.

Zhang Huixin said: "Wait a minute, Fang Yao, take a closer look, the stone that has just been taken out of the belly of the five-colored bear, this is an Arabic numeral 9, but there seem to be two horizontal bars engraved on the left side of this '9'. ”

Fang Yao frowned slightly: "It's indeed two horizontal bars, the mysterious person is really, and he didn't forget to make things difficult for us when he was about to end." ”

Stein took the stone and looked at it carefully: "This must be an equal sign, and since it is an equal sign, it means that if the numbers in these stones have a certain arrangement and combination, then we must find out the pattern, and place the stone with the numbers '9' and '=' in the last position." ”

Qin Lanzhi said: "I agree with Mr. Stein's speculation. ”

Equal sign? Math?

Fang Yao was no longer puzzled: "Since it is sure that it is an equal sign, then take a closer look at what the symbols on the left or right of each stone are, and then you can determine the order of the numbers." ”

However, everyone's eyes looked closely at the remaining three stones, only to find that they were only three numbers, without any hints of addition, subtraction, multiplication and division.

The stones are the "5" taken from the belly of the brown bear in the northern cabinet, the "3" taken out of the belly of the brown bear in the southern cabinet, and the "8" taken out of the belly of the brown bear in the western cabinet.

Zhang Huixin said: "Now it is clear that 9 is placed in the last place, and the meaning of the mysterious person is to use the three numbers 5, 3, and 8 to form a set of mathematical operations with a result of 9. ”

Ah, I don't have a headache, I'm not very sensitive to mathematics, it's better to say that liberal arts girls are more interested in mathematics or literature......

Fang Yao was still secretly spitting bitter water, and when the others didn't react, Zhu Shao blurted out: "This is too simple, 8 minus 5 times 3 equals 9." ”

Fang Yao was quite surprised: "Huh? So the order is 8539, it's that simple? Zhu Shao, how did you react, haven't you been in a state of confusion all the time? ”

The eyes of the others were also focused on Zhu Shao's face.

Zhu Shao was a little embarrassed: "Fang Yao, don't say I'm confused!" It's you and Xu Yueren who speculate about the mysterious people's 'twists and turns', I'm just not good at it. I'm not good at reasoning, I'm good at mental arithmetic, and no one is my opponent! ”

Qin Lanzhi said modestly: "Indeed, I have memorized many things, and my mental arithmetic ability is still a little behind Zhu Shao. ”

Xu Yueren said: "Since Zhu Shaodu has already come to the mouth of the Heavenly Chapter, let's believe it!" His wise saying, 'Whoever will be on it' is just right here. ”

Stein and Niu Xi had no objections, Fang Yao breathed a sigh of relief and checked the tablet: "There are still nearly 20 minutes left, we have plenty of time to rest." ”

"But Zhu Shao, I still have to ask responsibly, are you sure it's this combination order?" Just in case, Fang Yao asked Zhu Shao, who was very arrogant, for the last time.

Zhu Shao shook his head impatiently: "Nonsense, such a simple thing, be cautious!" After the mystery of the previous headache brown bear was solved, there was no difficulty in putting the finishing touches on it. ”

Fang Yao knew that it would be useless to worry about it any longer, and the possibility of secretly arranging and combining many numbers and arithmetic methods was not as refreshing and crisp as Zhu Shao provided. They are all excluded.

No longer hesitating, Fang Yao said loudly: "Since this is the case, then everyone will completely relax and relax, and after ten minutes, I will fill in the answer." ”

The ten-minute break did bring a valuable correction to the team, and the fatigued brain cells were fully relieved, and everyone's fatigue state could not be said to be swept away, but it could also be called a lot of improvement.

Fang Yao used the brown watercolor pen to write the four numbers "8539" on the notepad.

Xu Yueren suggested: "Fang Yao, it's better to write down the operation formula that Zhu Shao said just now, so as not to be denied by the mysterious person." ”

At this moment, before Fang Yao could start writing, the radio sounded: "Do I look like someone who denies it?" As long as you write out the four-digit password of 8539, the Demon Team will officially clear the customs. The key is on the inside of the watercolor pen. ”

So here?

Fang Yao bit her lip lightly, and a sense of being teased jumped on her face.

Xu Yueren also shook his head helplessly, took the watercolor pen in Fang Yao's hand, unscrewed the tail part, and dismantled the refill, and sure enough, the small key contained in it fell to the ground with a bang.

Fang Yao picked up the key and said to everyone: "Although sometimes the key is hidden close at hand, if we don't complete the problem and go to find the key, I'm afraid the mysterious person won't let us clear the level." So, in the next level, we still have to clear the level, get the key in a dignified manner, and shut up the mysterious man. ”

Everyone was very convinced of Fang Yao's leadership, and they also admired her wisdom and reasoning skills.

So, the puzzle of the third level was officially overcome, and Fang Yao opened the door and led the team members into the room of the fourth level.

The door to the third level closes again, and everyone is in the fourth level.

As soon as they entered the fourth level, everyone found an antique wooden coffee table with a kettle, as well as six small white closed jars of uniform system, and they didn't know what was inside.

To the right of the six small white jars, there was a man with a dark light-proof glass jar torn off the label and instructions, and a large black jar, apparently made of terracotta.

At the same time, next to these jars, three cups were placed.

The first cup is a jeweled jade cup with a long "handle" extending from the body of the cup, like a small tail.

The second cup is earthy in color and the characteristics are not as prominent as the first.

The third cup is more of a bronze curio than a cup.

It is the three kinds of cups of different shapes, as well as the jars, glass bottles, and small jars.

And, of course, the kettle, which is the most "normal" thing.

Next to the coffee table, there is an iron bucket there, filled with clean water. There is a scoop floating on the surface of the water.

The appearance of the water scoop and clear water, and then linked to the kettle, this combination is clear at a glance. In other words, this level must be solved with "hot water".

Overall, this messy set of things is piled up in the center of the room, taking up a lot of space.

Near the exit, is where the noteboard is located.

Unlike the silent clipboard that appeared in the previous level, this time the board has a clear question on it. And it's a long list, which makes people look like they have a headache to death!

Everyone followed in the footsteps of Fang Yao, put aside a series of strange items in the central area for the time being, came to the memo board shelf, and read:

Question 1 – Please use the correct utensils to drink the liquid in the glass jar and the liquid in the black jar separately.

Question 2 – Please find a way to taste the contents of the small white jar in turn.

The third question - please arrange the white jars correctly according to the color rules.

These three questions are unified in declarative sentences, but the difficulty is so great that everyone who has finished reading them has been beating back in their hearts.

Unlike the previous level, which seemed to be foggy and had few clues, the previous level only needs to find the "core" of the problem, and you can pass the level, in other words, it is a strong and meticulous logical reasoning ability.

In this level, it is not only necessary to test reasoning, but more importantly, to find the "answer" in vague prompts, which requires the knowledge reserve of the counterpart.

The fourth level is essentially a combination of the second level and the third level!

The difficulty has increased dramatically!

Fang Yao took a deep breath, pinched his palm with his thumb, and muttered to himself: "You can't give up, you have to do things one by one, and you won't know until you work hard!" ”

"The angels have a sea of light, although I don't want to admit it, Zhao Ting's sinister woman's IQ is also very high. I can't throw in the towel! ”

Cheering herself up, her eyes were no longer confused, so she raised her voice: "Everyone do what the prompt board says now!" ”

Seeing that Fang Yao was so combative, the others also lifted their emotions and came to the coffee table!
