The false sun hangs high in the air, casting shadows on everything in this world, as well as light and heat.

Lu Yuan and Su Mei have been thinking in the sun for a long time.

Lu Yuan’s inference about the world puzzle here is basically acceptable to Su Mei at present.

But you also need to review the questions in the world.

But how to examine this question is a question.

Could it be that you need to write and draw a picture of the sunset in the desert on the big stone to pass?

If this question is really like this, then Lu Yuan and Su Mei will still make it easy to break it.

After all, this is too cruel for non-art students.

Even art students, art students also broadcast and host musical instrument art.

"I've thought about it." Lu Yuan suddenly said.

"What are you thinking about?" Su Mei asked.

"Think about what the world wants us to answer." Lu Yuan said.

Su Mei felt that she hadn't thought of anything.

"Really?" Su Mei hoped to believe Lu Yuan.

"Yes." Lu Yuan nodded.

He jumped out of the pool water, which was one meter deep, almost flooding his lower abdomen.

The water is warm.

Lu Yuan turned around and stretched out his hand to Su Mei.

Su Mei nodded and jumped into the water together. The two of them moved forward together in the water.

"Can you tell me a little?" Su Mei asked.

This pool is very large.

As mentioned before, the radius is enough for three or four miles.

So it will take at least an hour to walk from one end to another.

Fortunately, Lu Yuansumei has enough time and will not be tired or hungry in this world.

So you can easily move forward.

"Yes." Lu Yuan said: "Look at this pool of water."

"I see this bowl, it's big and round, right?" Su Mei said with a curl of her lips.

"Well, look at this side, it is long and wide." Lu Yuan shook his head and said.

They had been looking at the pool of water for a long time. The pool of water was very clear and there was nothing inside.

"There is still the sun here." Lu Yuan continued.

The two of them said while wading in the pool.

"There is also a Gobi Desert here." Su Mei said.

Until this time, Su Mei still couldn't guess what Lu Yuan wanted to say.

Although nowadays, the two of them are already in harmony.

But now, I really can't understand each other, I'm so sorry.

"This may be a math problem," Lu Yuan said: "But I'm not sure, but I want to try it."

"What to try?" Su Mei asked.

"Try to open the door." Lu Yuan replied.

"By the way, you see, this situation is like what we saw on the bronze door before, about the scene when the earth was first formed."

Lu Yuan said this, and Su Mei remembered it a little.

When the earth was just formed, lightning and thunder were roaring and heavy rainstorms were storms.

The whole world is a thin pot of hot soup. Through Miller's experiments, it can be proved that the Earth gave birth to the original organic matter in this situation, and thus had the opportunity to slowly produce the earliest organisms like bacteria.

It can be said that bacteria are the most ancient residents of this planet.

Then what?

Su Mei feels a bit like that. There are pools and suns here. The temperature is almost the same as the temperature of hot soup, and there may be various inorganic salts.

"But there is no volcano erupting in the lightning and thunder here?" Su Mei asked.

"Because this is a test question, they don't want our lives." Lu Yuan said: "In short, this place can be roughly regarded as simulating the environment of the original earth."

Su Mei thought about it and felt that it still made sense: "But shouldn't this be a geographical issue?"

"No matter how bad it is, it is a biological problem?"

"Why did it end up becoming a math problem?"

Lu Yuan reached out and touched Su Mei's head: "Because this is a math problem."

After some conversation, the two of them slowly came to the other side of the pond. They could see that the big white stone was standing here, which was the most conspicuous sign here.

Lu Yuan climbed up the pond wet and came to the edge of Dabaishi with the water stains on his body. The water stains on his body slowly disappeared and he couldn't see it for a while.

Su Mei stood by the far side, waiting for the boy's performance.

I saw the road far away, stretched out my fingers, and began to write on the stone.

Lu Yuan wrote: "11=2."

Su Mei was shocked.

And the traces left by the fingers of the long road can really be left on the white stones, and they are almost black handwriting, which is very conspicuous.

The road was far away and he continued to write: "12=3."

“13=4.”

“14=5.”

Su Mei just watched Lu Yuan quietly write down all additions within ten on the stone.

At that moment, I was really confused.

But it's hard to say anything.

"Do you want to write a multiplication formula?"

"Wait." Lu Yuan said.

Continue to write on the slab: "10-1=9"

“9-1=8.”

Lu Yuan continued to write down subtraction within ten.

"The next is multiplication?" Su Mei asked curiously.

She had decided to watch Lu Yuan start his performance.

Lu Yuan nodded.

Continue to start writing: "1*1=1."

“1*2=2.”

"Can't you multiply the nine-nine-nine table?" Su Mei continued to ask.

Lu Yuan shook his head: "I think it shouldn't."

Su Mei was covered in black lines and watched Lu Yuan do division within ten again.

Is this bronze gate civilization just depends on your kindergarten problems?

Lu Yuan finished writing addition, subtraction, multiplication and division within ten.

The black handwriting on the white stone slowly disappeared.

Then, the same sound sounded in Lu Yuan and Su Mei at that moment.

Or it is an incomprehensible sound, but you can clearly feel the meaning.

It means “I understand.”

Lu Yuan smiled and said, "That's good."

Then, Lu Yuanjing wrote a lowercase e on the white stone.

Then.

“e=2.718281828459…”

The road is far away and down, writing, writing, writing ten, hundreds of flavors, and even thousands of them, and writing the entire white stone slab full of them.
