The system is the king of the counterattack master

Without understanding what she meant, Han Xiaodong also bent down and looked into the raised gap.

With the light of the wolf-eye flashlight, he could see that the gold plug was covered with a curved gold cover, and below it was connected a cylinder that was two circles smaller than the cover. There was a long strip about two centimeters in the middle There is still a certain distance between the bottom end of the flat hole and the countertop, and the entire plug can only be pulled out about five centimeters, and it seems that something stuck it below.

"Isn't this a drainage hole?" Han Xiaodong looked at He Xi in surprise.

He Xi shook her head blankly, as if she had lost her mind and was just doing mechanical movements.

"It looks like it's used to pour water into the countertops. It doesn't make sense. Why do you pour water into these tanks? For washing tanks?" Duan Muxiu raised his head after seeing the round hole, and rubbed it gently. Rubbing his face, he muttered to himself in puzzlement.

"It's filled with something, but it's not water. If I had to guess, I think it should be strong acid."

He Xi's gaze was still dull, and his voice was not loud, but it shocked both Han Xiaodong and Duanmuxiu.

If these four holes are filled with strong acid into the groove, then the flow direction of these strong acids...

The two people moved their gazes to the human-shaped depression at the same time. Although it wasn't too deep there, it was definitely the lowest point of the whole platform.

"Damn it, isn't it! Is the depression of this table just to pour acid into it?!" Duan Muxiu couldn't imagine the cruel scene: the person lying on it was gradually corroded by the strong acid slowly flowing through his body , the soul was writhing desperately in pain, but the body didn't listen at all, allowing the acid that slowly flowed down their bodies to turn their backs into a pool of bones, while the acid water combined with the flesh and blood was slowly filling up. The countertop, finally fused with the acid in all the grooves, forming rivers of red that flowed down the hollow below the body.

"It should be correct. These holes pour strong acid into the wiring on the countertop, and then collect it in the middle. When people are almost corroded, you can open the drain hole in the middle, and let the strong acid and flesh flow down the drain hole together. , to nourish something down here." He Xi looked at the human figure and explained, but the focus of her eyes was not on the human figure, as if she saw a farther time and space.

"How did you find out?" Han Xiaodong couldn't help asking, maybe this is what K was going to tell him just now, but He Xi saw through it, it seems that he really underestimated this woman.

"It's gold. I've been thinking about why they use gold. No matter how beastly they do it, this is an experimental facility after all. They will never spend a lot of money for such a waste of money for no reason. The only explanation is, This thing must have an irreplaceable role for him." He Xi explained.

"Anti-acid!"

Han Xiaodong immediately understood what she meant.

Gold is not comparable to copper and silver in terms of electrical conductivity and thermal conductivity, but it has a very special advantage, that is, it is particularly strong in acid resistance. Only aqua regia can cause damage to it, and it also has a strong resistance to acid Oxidizing, will not rust, let alone oxidation reaction, so for this kind of test that will produce violent reaction, gold is the best conductor.

"This circuit board is not conducting electricity at all, but is exporting the human energy cluster, which is the soul!" K added the last piece of the puzzle in Han Xiaodong's mind.

"These bastards!" Han Xiaodong couldn't help gnashing his teeth and burst out a foul mouth. This test bed under their feet, I don't know how many innocent souls have been "diluted and decomposed" here. Every inch of it is soaked. Full of Chinese blood.

"Damn it! Cutting up these bastards won't let go of their hatred!"

Anger almost made him lose control, and now he understands that the golden object in front of him is actually an extremely terrifying instrument of torture, and those who are placed on it will also suffer the most terrible death in the world—being tortured alive Corroded away.

The three of them were speechless for a moment. This was a terrifying discovery. If people really have souls, then this huge test bed must be full of grievances that can't go away.

"Let's go, I'm not feeling well." He Xi first suggested that such a scene is indeed a difficult thing for a girl to accept. No matter how tough she looks, she has lost her composure several times today. This time, it can be seen that she is also a female student in her bones, but she looks more domineering.

Now that she personally uncovered the secret of this test bed, it was somewhat unacceptable to her. After all, this was a bloody crime that had been buried in the ground for more than half a century. It was impossible to say that there was no fluctuation in her heart.

"Let's keep looking forward. If things go on like this, I don't think Zhou Hao and Xueqing's situation is optimistic. We need to be vigilant." Duanmuxiu said lightly, with a swollen face, looking at the golden table in a daze. .

Han Xiaodong nodded, and was about to get up with his backpack on his back, but He Xi grabbed him and said in a low voice, "Help me, I can't get up."

Han Xiaodong tactfully set up He Xi. He didn't know if it was because He Xi squatted for too long, or because he was so frightened by what he discovered just now. In short, he didn't intend to ask, and this kind of time is not suitable for asking.

After walking around the test bench and returning to the corridor, the three of them glanced at each other with incomparably solemn expressions.

But Duan Muxiu seemed to have thought of something, said "wait a minute", then returned to the table, took the flashlight up and down, left, and right, and finally stood still beside the table.

"Hey, what are you doing? Hurry up and leave." Seeing his abnormal appearance, He Xi thought to himself that he must be possessed by evil spirits again, and hurriedly frowned and shouted.

"Don't you find it strange?" Duan Muxiu said to himself with his back to the two.

"What's so strange? What's so strange, just tell me." The cracking of the secrets of this test bench is enough to make one's scalp tingle, and He Xi's patience is almost exhausted.

"It's solid." Duan Muxiu said without thinking.

Han Xiaodong supported He Xi, and the two walked quickly back to the table, looking at the place where Duanmuxiu's flashlight irradiated. It was a corner of the test bench. The whole corner was cut from a single piece of wood without any gaps.

"What do you mean?" He Xi asked angrily.

"He means, if your deduction is correct, how did the sulfuric acid get in there, am I right?"

Han Xiaodong looked at Duanmuxiu, his face was extremely pale in the peripheral light of the flashlight.

"You mean...my deduction is wrong?" He Xi looked at Duan Muxiu suspiciously, but she really hoped that her deduction was wrong, because the reasoning just now was too shocking.

Unexpectedly, Duan Muxiu just shook his head very slowly, his head was shaking very slowly, as slow as an old-fashioned shaking head fan.

Han Xiaodong and He Xi were very anxious to see him, but they saw him stretch out his hand slowly, and tapped his feet heavily with his index finger: "I mean, there is another layer under this one."
