Wei Zhen and An Xiaoyu didn't find anything in this huge laboratory, obviously someone had already cleaned up here, and the so-called useful things left for An Xiaoyu in the message couldn't be found, all of them were bottles and cans that didn't know their names.

An Xiaoyu was a little frustrated, what his father should have left for him was actually taken away by an uninvited guest, and he didn't know who took it.

Wei Zhen patted An Xiaoyu on the shoulder, the things left by his relatives were gone, anyone would be sad, just stayed like this for a while, Wei Zhen said: "Since there is nothing to gain, let's go back, and when we get to the shelter, maybe we will meet your parents." ”

An Xiaoyu turned around and looked at Wei Zhen's eyes, and the loss in his heart was slightly removed, fortunately, he is not alone now, although Wei Zhen is not very reliable...... However, for some reason, it can give people a feeling of reassurance, so he nodded and said, "Well, that...... Thank you, Wei Zhen. ”

"Thank you for what I did."

"No, it's so dangerous outside, and you won't leave me who I don't know...... You're such a nice person. An Xiaoyu whispered, her tone slight and shy.

"Ah, that's it," Wei Zhen is embarrassed to hear someone say thank you so formally, "It's nothing, I usually get a good person card, hahaha......"

"I'm not talking about the good guy card! I'm just really, thank you very much for your willingness to help me......" An Xiaoyu explained a little anxiously.

Wei Zhen touched his nose and said, "I know, I know, but I think it should be like this, okay, okay, let's go out quickly." Forking this topic, Wei Zhen pulled An Xiaoyu and walked out, An Xiaoyu was obviously a little dissatisfied with Wei Zhen's jumping on this topic, but he also followed him out of the basement.

When the two of them were about to go out, An Xiaoyu suddenly stopped, staring at the desk in the room as if thinking about something, Wei Zhen saw this and asked, "What's wrong?" Is there something wrong with this desk? ”

An Xiaoyu said: "I remember, it seems that I once saw my father have some strange behaviors in front of this table, what did it come from......" She frowned and seemed to be thinking about something.

When Wei Zhen heard this, he saw that An Xiaoyu seemed to be recalling, so he walked to the desk and looked at it, there was a long flat locked drawer in the middle of the desk, and there were three small drawers on each side, but they seemed to have been opened, and the documents inside were scattered on the side, Wei Zhen opened them one by one to check, which were all some documents that were not very important, or that Wei Zhen couldn't understand, and I didn't find anything after turning through them.

Just as he was confused, An Xiaoyu suddenly snorted softly, stepped forward and said to Wei Zhen: "I remembered!" Should be...... Wei Zhen, can you help me lift this table on the right? ”

Wei Zhen sighed, walked to the table, tilted the table with both hands, and the right leg was all off the ground.

An Xiaoyu completely pulled out a drawer on the right side and put it aside, revealing a layer of empty wooden boards below, which seemed to be table legs, but An Xiaoyu was groping around the corner of the table where he was raised, and his palm was slightly lifted upward, only to hear a click, the wooden board that fell to the bottom actually popped up and occupied the original drawer, An Xiaoyu was happy in his heart, and said, "It's okay, put the table down." ”

When Wei Zhen heard this, he flattened the table and squatted down, also interested in this hidden drawer: "Your father is still interested in researching this set of institutions?" ”

An Xiaoyu pulled out the flat and obviously half the height of the drawer, obviously like a wooden box with a lid, but An Xiaoyu didn't rush to open it, carefully looked around the box, and muttered: "I remember that this seems to have some mechanism......

Wei Zhen said: "There are still organs? I said, how do you know? ”

"I usually sometimes peek at my father's work, so it's normal to find this and make a fuss."

"What? Are you okay like to peek at your dad's work? Hey, your paternity is pretty bad. Wei Zhen quipped.

"You ......" An Xiaoyu was angry, but she didn't argue much, because she found a small hole under this wooden box, and said happily: "By the way, this is it!" ”

Wei Zhen leaned over, but only saw a garden hole with a diameter of less than one centimeter, can this be done?

After An Xiaoyu found this small hole, he casually found the refill of a ballpoint pen on the ground, and poked it into this small hole, not big or small, it was just right, and after this refill reached the lid of the wooden box, An Xiaoyu nodded, hesitated and said: "It can be opened, but ...... I always feel like it's dangerous. Therefore, Wei Zhen ......" After speaking, he looked at Wei Zhen with a look of pity on his face.

Wei Zhengang was still interested in seeing what was inside, and at this time, he saw An Xiaoyu saying that this thing might be dangerous, and now he looked at himself and obviously let himself open it, and scolded: "I said that you are grinding to open a box, even if you are a woman, but your guts have been gnawed by dogs at all, right?" I can drive, squatting next to me, and I want to die together. As he spoke, he took the wooden box, and then the whole person walked towards An Xiaoyu.

An Xiaoyu didn't expect Wei Zhen to suddenly come up and take advantage of this, and her heart jumped violently, but she couldn't dodge, so she had to let Wei Zhen stay by.

Wei Zhen didn't feel that he was taking advantage, the initial impression of hating An Xiaoyu hadn't changed at all, at best, it was just the indecisive and good old man's psychology in his heart that had been helping An Xiaoyu, and he would help anyone, so now he didn't think of taking advantage at all, holding the box in his hand, he hesitated, and then opened the lid.

The so-called danger did not appear, and the two looked into the box, but saw a notebook lying quietly in the box, and on both sides of the small hole where the ballpoint pen refill was inserted, an iron piece was separated by a ballpoint pen refill, blocking their connection, and at the iron plate connection was a row of copper wire lines around the wooden box, on which there was a battery circuit and a small packet of light yellow white crystals that did not know what were fixed on the line. There is also a small insulating rod on the open cover, which can be inserted into the negative pole of the battery when the cover is closed, blocking the battery's energizing circuit.

It seems that this is a simple energizing circuit, and if you don't insert an insulator, which is the ballpoint pen refill, open the lid and it will be energized immediately. However, the result of this circuit is that the battery is short-circuited, and the copper wire itself and the copper wire emit a lot of heat, but what can be done about it?

Wei Zhen didn't quite understand, but he was very interested in the crystal that looked like rock candy, and played with it in his hand.

An Xiaoyu took out the notebook and flipped through it roughly, there were quite a lot of experimental records recorded in detail, and there were a lot of photos mixed in, but most of the words were obscure and couldn't be understood at all, but after all, this was An Xiaoyu's father's thing, looking at his father's handwriting, An Xiaoyu also felt cordial.

Wei Zhen watched helplessly, and then said: "Eh, then look at what this crystal like rock candy is, does that note say it?" ”

An Xiaoyu flipped through the notes in his hand and compared the crystals in the box one by one with the photos in them, and soon found extremely similar things, and after taking a look, he exclaimed: "This is mercury thunderate!" ”

"What is mercury ramate?"

"Yes...... It's a chemical bomb! ”

"What......" Wei Zhen's hands stiffened, and he stood on the spot, "Blow up...... Bomb!? ”
