Ke Lie looked at the question and really didn't rush to answer this time.

Li Jianhua snatched it as he wished, and then he looked excitedly at Brother Duck next to him.

"What's the answer?"

Brother Duck is calculating.

"What's the answer?" Li Jianhua looked at the ten-second countdown, feeling a little anxious.

"Wait a minute, I'm new to chemistry."

Li Jianhua: "??" Damn, I paid 80 yuan to invite you here, you must not have graduated from primary school! !

"Hahaha!" Huang Tianci rolled on the table laughing, "Li Jianhua, you guys are really embarrassing hahaha."

Li Jianhua's face turned green, he was completely confused by this topic.

"Why do I feel that your topic is so simple, but ours is so difficult!!"

He couldn't say they cheated, because the questions were drawn systematically.

Anything is possible.

"If you can't answer, then we're here." Ke Lie sat on the chair, crossing his legs.

Hey, just for fun!

He knew it, his Ah Lin was a genius in all fields!

Qi Lin turned to look at Ke Lie, who blinked at him with a smug smile.

Qi Lin was slightly startled, and then smiled.

So, is this the feeling of youth?

Have friends and play together.

"Hahaha, it's so rubbish, Brother Duck can't do it!" Huang Tianci had been ruthlessly mocking for a long time: "You still call us children, I think you are the children."

"Ten seconds is up." Liu Yao also gloated.

Brother Duck didn't figure it out, and Li Jianhua almost punched him. Damn it, I wasted 80 yuan.

"The answer is A." Qi Lin looked at the question, but he didn't even calculate it.

Sure enough, the answer appeared on the screen, and it was indeed A.

Li Jianhua's face couldn't hold back anymore, Ke Lie and the others have already won four times! !

Win two more times and there's no point in playing!

"Next question." Huang Tianci chuckled.

The next question was a math problem, Ke Lie rang the bell directly, and Qi Lin said the answer.

The correct answer appears on the screen.

"Hahaha."

Li Jianhua sat on the chair with an ugly expression on his face.

That's it, damn it!

How many times have you lost to them!

We will have to call them Grandpa from now on.

Depend on!

He must not lose the last question! !

He looked at the bell, waiting for the question to come out.

However, the moment the topic came out, the bell on the opposite side rang again.

Shut it down, sorry.

He sat down on the chair: "The world is not worth it."

Looking at the topic, it looks like #?...^?& to him.

However, the person on the opposite side gave an answer, and it didn't take two seconds.

He gave the correct answer.

"Did he install a calculator in his mind?" Li Jianhua gave up the treatment.

"Fucking duck brother, refund the money!"

Brother Duck threw the money to him: "If you say you want to hit a primary school student, the person on the other side is not human!!"

After he finished speaking, he slammed the door out angrily. He had never been so embarrassing in his life.

"Are you fucking angry?!" Li Jianhua laughed angrily.

"Hey, grandson, come here, call grandpa, and get ready for your performance." Huang Tianci looked like a villain.

So comfortable!

This feeling is really good!Hahaha!
