The system is the king of the counterattack master

The downward road is dark, and at first the miner's lamp can still illuminate a distance of more than ten meters in front, but as the depth continues, the effect of the miner's lamp gradually weakens, and the air seems to gradually become thicker, swallowing the miner's lamp emitted light.

Han Xiaodong stood still and shone the light backwards. He found that the distance from the light did not change. He frowned. It seemed that it was not because there was something blocking the light in front of him, but because of his position.

"If I go on like this, will I become blind?" Han Xiaodong took off the miner's lamp, shook it forward a few times, and found that the movement speed of the light was not affected, but after a certain distance, it seemed to bump into a wall The missing wall is generally, completely absorbed.

"Yes, the rules are set by them. We have no way to change them. From now on, you have to be careful. This is a very smart passive defense measure. Once the light is completely swallowed, only those who are familiar with the situation can go to the goal. And someone like you who is not familiar with the situation can only walk forward in the dark, and no one can guarantee where you will go or what danger you will encounter, so..."

"So you just need to tell you if there is a way to go straight to the finish line without losing my life here." Han Xiaodong didn't want to hear an explanation at all, he just wanted to know how much his life would be in danger if he went any further.

"No!" K replied very simply.

"Damn! Then go back! Go back!" Han Xiaodong cursed, turned his head and walked back. If there is a maze in front of him, wouldn't he have a dead end?Even if it wasn't a labyrinth, it would be enough for him to have some mechanism or secret passage. You know, this kind of tomb dug by ancient people is the favorite thing to do.

"Don't, don't, it's not like there's nothing you can do!" Seeing that Han Xiaodong really turned his head and walked back, K immediately stopped him.

"Tell me, what should I do?" Han Xiaodong immediately changed into a threatening tone. He knew that K would not sit idly by, and he just came up with a way to ask for credit when he needed it.

"Do you know about bats?" K asked suddenly.

"I know, what's the matter?" Han Xiaodong asked subconsciously, but he immediately understood K's meaning: "Wait! You mean, the sound waves will not be affected here?"

The transmission of light is restricted, but the sound is not necessarily restricted. After all, if several people enter here at the same time, they will not be able to communicate.

"Storage cabinet No. B664, I have prepared things for you, just take them out and use them."

Han Xiaodong put his hand into his pocket suspiciously, and happened to touch an object in the treasure bag, and he knew that this was the puzzle-solving tool K had prepared for him.

He took it out, and looked at it with the light. It was an unremarkable rectangular box with two protrusions on the front. The outer shell felt like metal, very thick, heavy in the hand, and very heavy.

"Why did you give me an electric baton?" Han Xiaodong turned the thing over and looked at it several times. No matter how it looked, it looked like the anti-wolf electric baton sold on the Internet, and he couldn't help but doubt the function of this thing.

"Don't talk nonsense, fingerprints to unlock the lock, this is a high-energy sound wave detector, you can take off the rags on the top of your head." K has always called the things Han Xiaodong collected as rags. He is smart, but Han Xiaodong just likes to search for the lowest level of earth science and technology. It is like picking up leftovers in a garbage dump. There is really nothing worthy of praise.

Han Xiaodong took off the miner's lamp resentfully, and pressed the "electric baton" with his thumb, and the originally black box instantly emitted light blue light, which changed from weak to strong, and finally A three-dimensional dandelion emerged, and after a few swings, it exploded with a bang and scattered in all directions.

"Do you need to be so exaggerated? Isn't it just a sound wave detector? You have a lot of fun!" Han Xiaodong was confused by this weird scene and didn't know what to say. It was the first time he saw K doing such a boring thing. thing.

"It's called a boot animation! What do you know? A guy with no flair. Are you a human?" K immediately retorted. Although he was telling the truth, the last sentence sounded like a curse to Han Xiaodong's ears. .

"So much nonsense! How do you use this thing?" Holding the "electric baton" that was still emitting blue light, Han Xiaodong didn't know what to do next. Although the thing was turned on, he still didn't know how to operate it. Well, after all, K never gave instructions when making things.

"Wait, I'll let you witness the miracle later." K didn't tell him how to use it, but asked him to wait patiently.

After the dandelion drifted away, it gradually drifted away until it slowly sank into the darkness. Han Xiaodong didn't wait for the miracle K said.

"I said, you didn't tease me with a toy..."

Before he finished speaking, Han Xiaodong suddenly stopped talking. In front of it, a passage outlined by blue lines stretched forward quickly, looking like a scene in a science fiction movie.

"Woah...Are you kidding me? You didn't take out such a good thing earlier? Who would use a miner's lamp when there is such a convenient thing!" Looking at the clear and bright passage in front of him, Han Xiaodong felt that the things he had in hand this time The tools are indeed similar to rags. K rarely makes tools by himself, but every time he makes something, it can make people's eyes shine.

"Good steel is used on the blade. What you see now is the virtual picture I created for you with the outline of the sound wave feedback. The sound wave detector in your hand is not yet mature, because it is necessary to let everyone within 50 meters It is full of sound waves and requires a lot of power, so its continuous power supply time is very limited, you'd better find that basement quickly, or you will be stuck in the passage if the power is out halfway, don't say I won't help you."

Hearing this, Han Xiaodong glanced at the detector in his hand, it flickered on and off like a breathing light, thinking that K didn't lie to him, so he hurried forward along the passage.

After walking for about 5 minutes, Han Xiaodong stopped. In front of him, there was finally another fork in the road, but this time it was a crossroad, and there were actually three roads to choose from.

"Sure enough, it's tricky!" Han Xiaodong twitched his lips, thinking that thanks to K's help, otherwise he would have to learn the truth today.

But even so, the bifurcation still caused him quite a headache. The power of the detector in his hand is limited. Say, he only has a one-third chance of choosing the right path.

"Take the road to the left." K suddenly extinguished the images of the other two roads.

"How do you know this is the road? Isn't it only possible to detect a distance of 50 meters?" Han Xiaodong couldn't understand K's approach.

But K smiled triumphantly, and strengthened a small detail of the image on the left channel: "Look carefully, someone left a mark for us!"
