Chapter 1151

1203. We all don't know how to get in, but Huo Yunshen knows the way. He uses his hand in leather gloves to brush off the frost and snow on the door. Soon, there is a smooth ice surface like a mirror.

Everyone noticed that there were words on it.

Generally, people who don't understand the characters of the Dragon kingdom may not know them, but ye Xun read them subconsciously.

Let ∮ x f (y) dydz + YF (x) dzdx-z [B + F (x + y)] DXDY Find f (2010). "

After reading it, I couldn't help shouting, "i-shit, I'm going to change! It turns out that there is an advanced mathematics problem on it. Don't tell me. You can't go in until you answer it correctly. "

Ye Xun couldn't imagine what a strange person Qi Zhengming was, but there were few questions on the door since ancient times.

What a weirdo!

Jun Yan frowns, "ask me how much one plus one I know, but advanced mathematics, can't!"

Thinking of Xu Xiyan's good performance, Jun Yan turned around and asked, "Xiaoxi, will you calculate?"

Xu Xiyan has long returned what he learned to his teacher. Now, where can he do such a difficult problem.

At a time when there was nothing to do, Huo Yunshen had picked up the dagger and solved the problem on the ice.

The final answer is f (2010) = 2010a-2009b.

When Huo Yunshen focused on the topic, several people were stunned.

There is no harm without comparison. Now you know what is learning slag and learning bully?

Their boss turned out to be a math genius!

Xu Xiyan doesn't know how to worship her man. In a word, she thinks her man is an all-around genius. It seems that without him, she can solve such a difficult problem. It's really powerful.

After giving the answer, the magic time came, and the ice door opened automatically, showing dazzling white light. Several people were slightly narrowed by the white light stabbing eyes.

"Come on, you can go in."

Huo Yun takes Xu Xiyan's hand deeply and goes in first.

as like as two peas in the back of the BOSS, they always feel strange when they see their people pulling the same figure.

Ye Xun also followed, and several people entered the door.

When they came to Lingdao, they found that there was something else.

It seems that there is a huge glass cover on the island. There is no howling north wind and thick ice and snow in the island. It is a paradise and a colorful world.

"I -- rely on --"

Ye Xun can't help exclaiming again, "how can it be a few drops here?"

On the green grass, there are lovely rabbits eating grass, flowers blooming, butterflies flying.

In the distance, there are mountains, waterfalls, gurgling streams, beautiful mountains and forests around.

"Must be an illusion!"

Jun Yan is very surprised. Probably no one would think that there is a paradise under the ice.

"It must be an illusion!"

Xu Xiyan can't believe his eyes. It was just freezing. How can another beautiful scenery appear now?

It's like walking into a strange world full of magic.

And it's not as cold here as it is outside.

As soon as Xu Xiyan came in, he felt the temperature was high. He was wearing a down jacket, so he took it off quickly.

Huo Yunshen took several people into the room. There was a thatched hut in front of him, which was his master's residence.
