Xu you a listen, Leng under, then immediately understand the value of Yu Xi.

"Haha, you're right. Oh, I'll just say, you're absolutely true in TV, right?"

Yu Xi said, "how can it be? I guess it casually."

Xu you thinks that now Yu Xi hasn't gathered enough four people. If he can gather enough people by then, they will be enemies, so. He came right up.

"In fact, I can give you this one. It's also simple. It's something that tests your intelligence. But a person can only take one box. I got one of the questions right, so I took it away. But I gave it to you, and I can get it later."

Yu Xi was not polite. He knew that he was making advances. He looked at it and said, "there's Li Yu. Let's go in and have a look. "

"That's right. If we take one box, we will have three boxes, and there will be four boxes inside."

Yu Xi followed him in, which was set up as a room with a sense of science and technology.

There are four tables for boxes, one of which has no boxes.

The other three boxes are well embedded in them.

Li Yu looked at it and asked anxiously, "but I can't do anything. What can we do about that? "

Yu Xi said, "it's OK. I'll help you. Let's go and have a look. "

As we passed by, the radio suddenly rang.

"Welcome to Dr. w's laboratory. Dr. w has died in order to fight against zombies. However, the research results he left behind are now distributed in four boxes. In order to help more human beings with the research results, Dr. w has set up a test for heroes. People who can solve the test with intelligence can take away a box, It contains the secret of saving mankind. "

Yu Xi said to many Yu, "you go first."

Li Yu Yu feels that Yu Xi is just a goddess. The goddess speaks. Of course, he immediately obeys.

Li superfluous hand goes in, an examination question stretched out directly.

Li Yu was startled, but when the question came out, he was already stunned.

A math problem??

Li Yu said, "wipe, I failed in math."

When Xu you saw it, he was confused.

"Wow, I really can't. Fortunately, the one I just did was simpler, which was to unlock a nine palace grid. "

Yu Xi looked and said, "don't move, I'll have a look."

Li Yu looked at it busily, "Wow, can you still solve math problems?"

Joke, how much programming, so much more difficult than mathematics, is not a little bit to solve.

Yu Xi's math is good, especially for this kind of strange looking math problem. Solving the problem is like solving the program of a website, step by step, patiently, and even has a sense of achievement.

Yu Xi quickly wrote up and calculated the mathematical equation of a piece of paper, which surprised Xu you.

"Wow, Yu Xi, people say you are Xueba, but I don't believe it. It turns out that this is not the one your company set up for you."

"What kind of person set up, when I was a Xueba person set up." Yuxi Road.

"What kind of person do you set up?" Xu you asked.

Yu Xi said, "I'm not black all over the Internet."

Poof.

Xu you said, "it's the same, but are you doing the math right. The people watching in front of the TV are quite a few students. You're not doing it right. At that time, people will say that we are scripts. "

Yu Xi said, "there's no way. What I do right is more likely to be said to be a script. Right

"Yes, I will say we will give you the answer ahead of time."

Yu Xi said“ It's good that I can write down the answer step by step, OK

When two people say, Yu Xi has already untied.
