Chapter 207 (1/2)

After climbing over the body of the giant crocodile, Beiling and Xiaotan move on. Because they had already walked this way before, when they walked again, they quickened their pace unconsciously. A few minutes later, they passed the first strange place.

After another period, they were suddenly enlightened. The tunnel gradually widened and finally connected to a very large cave. Stalactites are distributed on the ground and on the top of the cave. Under the light, these crystals are colorful and various in shape, which is a wonder. Because the surrounding rock walls are rugged, which are hidden by the stone group, you can't see the whole cave at a glance.

”Look for it separately See if there is a tunnel leading to other places. ” Said the sad spirit.

Little sigh nodded and pointed to his side: ”then I'll go there.” Then he walked away.

Both of them have their own lighting equipment, and the sound transmission effect in this hole is good. As long as there is no fork in the road, there is no need to worry about the problem of separation. So Beiling didn't talk about it any more. She went to another direction quickly.

Unfortunately, Beiling's luck is not so good. She soon lost her way on that side. After crossing a pothole of water, she saw a large pool in front of her, which was similar to the one she had fallen into before. But the top of the cave here is closed, and the stone walls surrounding the water pool three sides also declare that this is a dead road.

She turned around all the way, and soon came to the place separate from Xiaotan, and then she went in the direction Xiaotan had just gone. Not long ago, I saw the elongated shadow of light and small sigh behind a rock in front of me.

Xiaotan also heard her approaching footsteps, and leaned back from the corner. ”Did you find anything there?”

”No way.” The spirit replied, and immediately asked, ”what about you? What do you see standing there? ”

”I seem to have found a door.” Small sigh returns a way.

”Oh?” The sad spirit has come to Xiao Tan's side, and she also sees the so-called ”door”.

It's a three-dimensional octagonal sphere. The surface of the sphere is metallic and its volume is larger than that of a refrigerator. It's right in a place that looks like a tunnel entrance. The device faces their side. The color of a piece of metal in the middle is obviously different. When you touch with your hand, a game menu will appear in front of the player. At first glance, it is obviously a very pure game setting, which has nothing to do with the world view of the script.

”Is it a puzzle...” Asked the sad spirit.

”Touch that place with your hand.” Little sigh pointed to the metal of different colors.

The sad spirit took a look at him. Then I stepped forward and touched the place where the little sigh pointed out with my fingertips: ”Oh, this kind of puzzle...” When she saw the topic in front of her eyes, she immediately changed into a relaxed look, and her tone was a little complacent.

”Ah That's the question. ” Little sigh.

”You are standing here. That's what it's about? ” Asked the sad spirit.

”Yes, but as soon as you come here to talk to me, I'll forget all I thought before...” Small sigh returns a way.

”The answer is seventy-five.” As Beiling said this, she drew these two Arabic numbers on the metal with her fingers.

In the next second, the surface of the metal sphere suddenly became the same color as this one. Then it opens slowly from the top like a blooming bud. Pieces of metal plates were folded and laid on both sides of the tunnel and on the ground, unlocking the passage in front of the two men.

And in the middle of the sphere, there is a piece of equipment, which is displayed in front of them at the moment.

Small sigh surprised way: ”you calculate so fast?”

”Small.” ”Sad spirit looked up at him:” I usually have more difficult topics to play when I have fun

The puzzle just now is actually a Sudoku problem of nine times nine, and it has given quite a number by default. It is a relatively simple difficulty, and the game menu does not require players to fill all the empty spaces. It only needs players to figure out the numbers of a few specific points and find the sum.

Even the third grade students can solve the problem, but it may take more time without the help of paper, pen and other recording tools.

To put it bluntly, it's a puzzle that tests the ability of short-term memory, mental arithmetic and logic deduction. It doesn't need extra association or the like. It can be said that it's the strongest item of the spirit of sorrow.

”Your usual recreation is terrible Are you a mathematician? ” Said little sigh.

”I'm good at liberal arts.” Pathetic way, ”besides Where is such a young mathematician? I just graduated in two months

”Is it I always think you're like a science bully. I didn't expect that. ” A little sigh.

”I don't think you're like a doctor. You're as timid as a mouse.”

Xiaotan just laughs and doesn't explain anything. He goes forward and looks at the equipment inside the metal body and says: ”you can pick up this thing. In case you pick it up and bind it.”

”I can't use this at first sight. I'm really picking up binding. I'll take eight achievements to the store.” ”Sad spirit replied:” or you pick up She is right, because the object on the ground looks like a pair of boxing gloves. Players with shooting expertise can't even pull the trigger. It's meaningless to have them.

Small sigh smell speech, then the past will take the goods to the hand.
