Everyone watched as they watched in shock, took out a scratch paper, brushed a few formulas, and began to calculate them with a little concentration.

The teaching director is going crazy, Xu Chengyu is a well-known good baby, why is he messing around now!

It must have been broken by Gu Yao!

He turned his head, only to find that Gu Yao was looking in one direction, and the corners of his mouth were upturned......

Can this kid still laugh?

The psychological quality is really good.

Xu Chengyu quickly figured out the answer, "According to my calculations, the suspect's height should be around 178cm." ”

Gu Yao: "Thank you for my 183cm." ”

The director stared at his shoes suspiciously, "You didn't put on the height insole, did you?" ”

Gu Yao: ......!!

Soldiers can be killed, but not humiliated!

He said coldly: "The net height is 183cm, put on shoes 185186cm." ”

Director:...... What to do if you suddenly have a heart congestion.

"Teacher, there is one more thing that can clear Gu Yao's suspicion." Xia Xi's voice is soft and sweet, not in a hurry, "A girl's size 43 is 26.5 cm, and a boy's size 43 should be 27 cm." ”

One by one, the people in the class seemed to have watched a TV series, and a thought popped up in their minds:

Knowledge is power......

The fat man was the first to coax, "Ouch, it's a trick!" Abuse lynching! Forced confession! ”

Gu Yao spread his hands, "Teacher, I'm so weak, how can I rob elementary school students?" It's good that they don't rob me. ”

"Shut up!" The dean of teaching was annoyed and angry, "What is Gu Yao talking about? Didn't rob elementary school students, but you were terrible? You can't run away from fighting! Give me a 10,000-word review tomorrow! ”

Gu Yao reminded, "Tomorrow Saturday." ”

"Then pay it on Monday! Recite it in front of the whole school when the flag is raised! ”

The dean left in a huff, and the onlookers dispersed.

Gu Yao returned to his position, supported his face with his elbows, and squinted at Xia Xi, "Little short legs, you know a lot." ”

Xia Xi said shyly: "I just saw ...... before"

"What a humility! Xixi, I declare that you will be my sister Xi! Our seventh middle school F4 officially debuted today! ”

Xu Chengyu: "What is F4?" ”

Fatty: "You don't know that?" flower-four, four flower-like beautiful boys. Few. Woman! ”

Xu Chengyu: "...... Teenager, I can understand, is there any inevitable connection between beauty and you? ”

Fat man: "Ahhhhh Brother Yao, you have to administer justice for me! ”

Gu Yao said calmly: "The three of us are flowers, and you are chemical-fertilizer." ”

The fat man, who was a scumbag, was about to vomit blood, so he asked Xia Xi pitifully, "Sister Xi, what did he mean?" ”

Natsuki hesitated and said cautiously, "Chemical fertilizer." ”

Xu Chengyu added, "Referred to as chemical fertilizer. ”

Fatso:......!! I can't live this day!

Huh~ Pity him for being a scumbag in elementary school, and it is difficult to survive in the gap between these three school tyrants.

"Good, go buy a few buckets of instant noodles and come back, dad is more love-you."

"Who are you taking advantage of? Who wants to be your son!! ”

Gu Yao threw his wallet over.

The fat man changed his words in a second, "Daddy, I'll go back when I go." ”

Xia Xi was amazed, picking up the dogleg skills of being a little brother, she is still far from the fat man......

The fat man bought instant noodles and came back, he didn't know where to bring back a hot water kettle, poured hot water one by one, and handed Gu Yao a bucket flatteringly.

"Brother Yao, I added braised eggs and ham sausages to you!"

Gu Yao let out an "oh" and handed it to Xia Xi casually, "Hey, little short legs, don't learn it, it's stupid to learn again, eat some junk food to replenish your body." ”
