Huo Chi stood in the center of the "phone booth", thinking carefully about how to find the little golden key in this mess.

The key is not the same as the previous thing, it is not a living thing, and it should not be possible to find it through the materials at hand.

Huo Chi felt like he was in an escape room-like game now, but the game he was facing had no hints at all, and the time limit was so short, how could he escape from here?

Huo Chi was thinking quickly, but his eyes didn't stop at all. He kept searching for the little key in the pile of objects, and suddenly, a picture of a small piece of gold caught his attention.

The color is very similar to the key, isn't it the key? Huo Chi glanced at the time, it was already 2:15, and he had been delayed for more than forty seconds since just now.

There are still three hearts, and Huo Chi decided to gamble. He carefully reached out and touched the little golden spot, trying not to touch anything else.

When his hand finally touched the bright spot of gold, the picture suddenly shook violently, and then, one of the three hearts in the upper right corner of Huo Chi's vision was deducted.

Just when Huo Chi felt a little frustrated, he found that the bright spot of the gold he had just touched gradually became larger, and then, it squeezed out of the picture and fell to the ground with a click.

The golden thing was about two fingers wide, and it looked like a regular cuboid, and there seemed to be two bumps at the top of the cuboid, huh? It looked a bit like a battery.

"An alkaline battery?" Huo Chi picked it up, the appearance of this battery is golden, and there seem to be a lot of patterns on it that Huo Chi can't read, he looked at it for a while, and felt that these patterns should be useless, but why did the battery fall out of the picture?

The game deducted Huo Chi's heart, which means that he clicked it wrong, but the battery that was wrongly clicked fell out, which is strange. Could it be that this game is not just about finding your sister, but also has some decryption elements?

Huo Chi gestured at the brown door, and it didn't look like it could be opened with a battery drive.

Since that door doesn't make sense, shouldn't you find something that can use the battery?

Huo Chi looked at the picture and glanced at it for a while, and he really saw something that needed batteries.

It looks like some kind of baton, but the baton as a whole looks rectangular, which is very different from a cylindrical baton.

Huo Chi felt as if he had seen such a thing somewhere, by the way, wasn't this the handheld metal detector that the security guard held in his hand when he used to ride the subway?

It dawned on him that the key was metal, and could this metal detector be used to find the missing key?

But the pile of items is so messy, is there other metal mixed in it?Huo Chi looked closely, but felt more and more that the metal detector might really work. Because don't look at the piles of items on the walls, but when you look at it, there really isn't anything made of metal.

I don't know if there is metal underneath these things, Huo Chi can't see the situation under the pile of items, but time is constantly draining, and it doesn't leave him any time to wait.

A decision must be made as soon as possible, Huo Chi mustered up his courage and reached out and pointed at the metal detector. The picture immediately shook, and a heart was deducted again.

Huo Chi has less than a minute left in his time, and there is only one heart left. Seeing that the metal detector was slowly squeezed out of the picture, Huo Chi hurriedly stepped forward to catch it.

The metal detector was still a little heavy in his hand, and he opened the battery cover under the grip, and sure enough, as he guessed, there was no battery in it!

Huo Chi decisively stuffed the battery inside, closed the battery cover, opened the metal detector, and began to sweep the wall.

The sensitivity of the handheld metal detector is not very high, so Huo Chi has to be more careful to sweep closer to the wall little by little, lest he miss anything.

There were still twenty seconds left, Huo Chi had just finished sweeping the two walls, and in addition to the wall of the gate, Huo Chi still had a wall to try his luck.

The metal detector in his hand didn't make any sound, but Huo Chi's heart was pounding, he was actually very unsure in his heart, after all, all the clues he found were deducted from his heart. And it's a coincidence that the battery is in your own hands, can you find the key?

"Woo-" The metal detector suddenly sounded, and Huo Chi repeated it twice where it came from, making sure that the sound was coming from the only exposed floor tile that had not been piled up by objects.

Where is the key? Huo Chi wondered in his heart, but the sound made by the handheld metal detector when it swept over here meant that there must be metal in this place.

There were less than ten seconds left, Huo Chi gritted his teeth and let go! Isn't it the floor tiles? He reached out and pointed at the floor tiles.

The ordinary-looking pattern of floor tiles suddenly opened, and there was a hidden compartment under the floor tiles, and the small golden key was in the dark compartment. At the same time, the countdown time was finally fixed at 0:01, which was really a thousand shots.

Huo Chi stretched out his hand and took out the small key and walked to the door. He inserted the key into the keyhole of the doorknob, and the flat doorknob suddenly clicked, and then the door opened.

Outside the door was the familiar gray corridor, Huo Chi, who had been trapped in this small space for a long time, rushed over without hesitation, and the door disappeared immediately after closing behind him.

Huo Chi looked at the metal detector in his hand and said, "Abu, I really want to forget to take what I can eat in there." ”

"Didn't you take it?" said Abu.

"What do I take?" Huo Chi looked at the metal detector and was blinded to find that there was indeed a line of small print on the handle of the detector: golden eel horn.

Golden eel horn?Huo Chi felt a little dizzy, isn't this a handheld metal detector? This thing is actually a monster thing?

He played with the metal detector in his hand a few times, and realized that the small print did not seem to refer to the metal detector itself.

By the way, there's a battery in the detector. Huo Chi opened the battery cover and pulled out the battery inside. Sure enough, the small print slipped out along with the battery, is it really a battery?

Last time, I ate mats, stones, and bricks, but this time it was even more awesome, and I had already started to eat batteries, Huo Chi was speechless for a while, and clicked on the flickering monster eating guide.
