Yu Lin walked to one of the trash cans, and just lowered his head to look for it, only to see an admission ticket lying quietly at the bottom of the bucket.

The entire trash can, not even a single scrap of paper.

Yu Lin took out the admission ticket from the bottom of the bucket, confirmed that the admission ticket was written in his name, and then put the admission ticket in his pocket with peace of mind.

On the side, Ji Xiao looked at his clues dumbfounded, and before he could analyze it, he saw Yu Lin find his own admission ticket from the trash can, and immediately exclaimed:

"Sister Lin, you found ??!"

Yu Lin bowed his head.

Seeing that everyone was analyzing their own clues and already had ideas, Ji Xiao decisively chose to hug Yu Lin's thighs:

"Sister Lin, save me!"

[Hahahahaha

[Laughing to death, worthy of being my goose in the sky, able to bend and stretch hahaha]

[I have to say, Ji Xiao's luck is really awesome, and the eyes of hugging his thighs are the same]

[You see Ji Xiao's eyes when he saw Yu Lin when he found the key, hahahaha, really, shocked]

Seeing Yu Lin agree, Ji Xiao hurriedly presented his clue card with both hands.

Yu Lin took it, glanced at it briefly, and subconsciously sighed: "It's really different from the first clue card." ”

The clue card handed over by Ji Xiao was densely packed with words, and even the font size was visibly twice as large as Yu Lin's.

[Help, hahahahaha

[I'll go hahahaha, can this dense still be called a clue hahaha, it's better to find the clue directly if you have time to solve it hahahaha]

[Your sister Lin is a little humorous and has a lot of humor on her body hahahaha]

[Yu Lin's emotion I can laugh to death hahaha, I almost laughed when I just ate]

Ji Xiao's clue card is a high school math space vector problem, not surprisingly, the final solution should be a coordinate.

Just the stem of the question is already densely written with two lines of words, not to mention the complex graphics drawn under the title.

[Dead High School Knowledge Suddenly Strikes Me]

[I am a high school student, saying that this question is not difficult, but it is very troublesome to calculate, and it is impossible to do mental arithmetic]

[I'll go, I'm already starting to have a headache when I look at this number, and I can't move an inch without giving me paper and pencils]

[I'm a college student, and I can't understand it anymore, but my intuition tells me that this question is difficult to calculate]

Yu Lin roughly swept the whole question, and then said in a casual tone: "The calculated coordinates are (2,1,3), find out if there is a place marked with a coordinate system in the corner, and then you have to find the reference system." ”

Ji Xiao slowly typed three question marks, constantly feeling that his three views were refreshed, he hesitated and asked:

"Sister Lin, what are you ...... Mentally calculated? ”

Yu Lin nodded subconsciously, yawned and said lazily: "It's too troublesome to find paper and pen, just use this result to try it first." ”

Behind the Xuanmen Mathematics is the calculation between the huge Zhoutian Bagua, and the hexagrams corresponding to each moment are different, and in order to master them, the ability to mentally calculate in a short period of time is essential.

Therefore, Yu Lin basically scanned the question at the moment when he had already calculated the answer in his heart.

But apparently, what seemed to her to be a habitual behavior was a completely explosive effect in the eyes of others.
