The melodious piano music dispelled the sound of Zhang Tingxiu's stir-frying, and Zhang Tingxiu's mood became a lot more cheerful.

The little head shook and followed the rhythm of the music, and before I knew it, the meal was ready.

The two sisters sat down together and enjoyed the food, and Zhang Tingxiu didn't say anything about a quiet person at the table, let alone eat quietly.

chewing on food in his mouth, and chattering; "Sister, why did your brain suddenly become better? What the hell is going on! ”

Zhang Xiaoyun was a little ...... by these words Tomorrow, [Brainy?] Does it mean that you didn't have a good brain before? 】

Zhang Xiaoyun was inexplicably annoyed by Zhang Tingxiu's words, and Zhang Xiaoyun slapped the table domineeringly and said viciously; "How about we play quiz!"

Zhang Tingxiu looked at Zhang Xiaoyun in a daze, and then her eyes became disdainful; "Cut...... It's up to you...... Also quiz! ”

Zhang Tingxiu thought about it for a moment and remembered what she saw on the Internet, so she asked.

Zhang Tingxiu coughed in makeup; “13。 1 yuan for a bottle of soda, after drinking two empty bottles for a bottle of soda, ask: you have 2o yuan, you can drink a few bottles of soda at most"

Zhang Xiaoyun is so smart at this moment, he doesn't pretend to be colorful; "There is no problem with 2o bottles at the beginning, and there is no problem with the subsequent 1o bottles and 5 bottles, then divide the 5 bottles into 4 bottles and 1 bottle, the first 4 empty bottles are replaced by 2 bottles, and after drinking, 2 bottles are replaced with 1 bottle, at this time, the number of empty bottles left on hand after drinking is 2, and these 2 bottles are replaced by 1 bottle"

Her riddle was answered by Zhang Xiaoyun instantly, which made her feel extremely annoyed, and Zhang Tingxiu continued to ask; "There are two incense sticks that are not evenly distributed, and the time it takes for the incense to burn is one hour, what method can you use to determine a period of 15 minutes?"

Zhang Tingxiu's thoughts; [Hehe, you can't answer it instantly, it's definitely going to be drafted!] 】

And Zhang Xiaoyun only thought about it for a few seconds and replied; "Suppose the two sticks of incense are A and B, and light the two sticks of incense at the same time, where A lights both ends and B only lights one end, so that when A burns the ember, it takes 3o minutes, and then the other end of B is lit until B burns the ember, which is 15 minutes."

I saw Zhang Tingxiu's face surprised, as if she had seen a ghost, and slapped the table viciously; "You must have known the answer! Otherwise, how could you have answered it in an instant. ”

Zhang Xiaoyun looked at Zhang Tingxiu playfully and said lightly; "You! At! Envy! Jealous! I! ”

Zhang Xiaoyun had a bad smile on his face, and he kept beating him when he spoke, but he pretended to be extremely forced, and he was beaten to the extreme.

Zhang Tingxiu clenched her fists, eager to swing a punch on Zhang Xiaoyun's face.

Zhang Xiaoyun said lightly; "Alright, now let me ask you."

Zhang Xiaoyun thought for a moment and said; "A group of people had a ball, each with a hat on their heads. There are only two types of hats, black and white, and at least one black one. Everyone can see the color of other people's hats, but not their own. The host first asked everyone to see what kind of hat other people were wearing, then turned off the lights, and if anyone thought they were wearing a black hat, they would slap themselves. The first time the lights were turned off, there was no sound. So I turned on the lights again, and everyone looked again, but when they turned off the lights, they were still silent. It wasn't until the third time that the lights were turned off for the third time that there was a sound of crackling and slapping. Q: How many people wear black hats? ”

Zhang Tingxiu instantly felt that her IQ was not enough, which ...... This kind of topic is too complicated.

Zhang Tingxiu is such a cute and cute author, no matter how you think about it, she has no clue.

Although it took time to write a draft, Zhang Xiaoyun did not write a draft.

If she writes a draft, wouldn't she be inferior, will Zhang Xiaoyun look down on it, Zhang Xiaoyun can also think of an IQ like her, why can't she.

So Zhang Tingxiu has been thinking about it all the time, and Zhang Xiaoyun has already eaten the food and is ready to rest in the room.

She doesn't want to tell Zhang Tingxiu the answer, if the answer is told to Zhang Tingxiu, then Zhang Tingxiu can be relieved.

But at this moment, Zhang Xiaoyun just wanted to embarrass Zhang Tingxiu, who made her keep saying that she had no brains.

So Zhang Tingxiu was forced to do it, although Zhang Xiaoyun had already left and returned to the room, it was no problem for Zhang Tingxiu to take out paper to write a draft at the moment.

After all, Zhang Xiaoyun won't know, but Zhang Tingxiu also has her own arrogance, she definitely doesn't write drafts, she must use her own IQ to come up with it!

So Zhang Tingxiu had insomnia, but at the cost of being hollowed out of her IQ, the answer was finally figured out, and it took more than three hours.

The next day, Zhang Tingxiu proudly ran to Zhang Xiaoyun, crossed her waist and stared at the black circles; "Hey...... I figured out the answer, and the answer is xxx (the answer is very long, so I won't lie about the word count.) )”

After speaking, Zhang Tingxiu squinted and looked up at the ceiling, in her opinion, her stupid sister of this generation would definitely worship herself to death, and call herself 'sister'.

So Zhang Tingxiu was looking forward to it, looking forward to it...... Looking forward to ......

Who would have thought, Zhang Xiaoyun said lightly; "Get out, don't disturb my rest!"

At this moment, Zhang Xiaoyun is still lying in bed and sleeping lazily! was disturbed by Zhang Tingxiu kicking the door open, Zhang Xiaoyun was really unhappy at the moment.

The happy face froze on Zhang Tingxiu's face, and the pretty face quickly warmed up, it was not shyness but annoyance.

The emotions of shame and indignation were wrapped around her heart one by one, Zhang Tingxiu screamed, babbling and threw herself on the bed.

Directly on Zhang Xiaoyun, Zhang Xiaoyun's eyes widened, and he almost vomited stomach acid!

clutching his stomach in pain; "What are you doing!"

And Zhang Tingxiu is already crazy at the moment, embarrassing her with a difficult topic, she didn't sleep well all night.

The question didn't answer Zhang Tingxiu, so she couldn't sleep, so she fell very late unconsciously.

The embarrassed and angry girl scratched Zhang Xiaoyun's body, shouting in her mouth; "Xiao'er, watch the old man pinch your ...... Big, chested. ”

The foul language in his mouth Zhang Xiaoyun was also red-faced, red-faced, heartbeat-heartbeat, and heavy breathing.

So Zhang Tingxiu was kicked out of bed by Zhang Xiaoyun unceremoniously, and Zhang Tingxiu's little face turned red when she stood up.

Fingers trembling and pointing at Zhang Xiaoyundao; "You...... You...... You're so ruthless, I'll kick out of bed! ”

Zhang Xiaoyun looked at Zhang Tingxiu in astonishment, Zhang Tingxiu's young heart seemed to be hurt by herself at the moment, so Zhang Xiaoyun looked at Zhang Tingxiu apologetically.

Scratching his head; "This ...... I'm sorry, did it hurt to fall, or I'll help you rub ......"

Zhang Tingxiu jumped above Zhang Xiaoyun with another leap, and seeing that she was about to press on Zhang Xiaoyun, Zhang Xiaoyun subconsciously stretched out her hands.

Impartial, grasping softly somewhere, Zhang Tingxiu was stunned in an instant, and Zhang Xiaoyun subconsciously pinched and kneaded, disgusted; "What a little ......" (To be continued.) )
