Although after the destruction of an explosion, the devils destroyed it again when they evacuated, in the eyes of professional He Quanhui, this area still has traces to follow.

"Look, this trace." Pointing to the fan-shaped impact groove on the ground, He Quanhui said: "Although it is a little vague, if you shovel away the floating soil above, I estimate that the deepest place is at least ten centimeters, I don't know what kind of conventional bomb can have such an effect, you look at the reinforced part of the concrete, it completely disintegrates." ”

"I know, it was burned." Zhang Ran pointed to the concrete gate of the cave.

He Quanhui's movements were very fast, and after taking pictures of the area at the door, he walked towards the gate, Zhang Ran and the others quickly followed, and before He Quanhui in front of him really walked into the swarthy cave, Tang Xiaobing suddenly shouted: "Wait a minute, Geiger counts." ”

"How much?"

The Geiger counter detects the radiation index, and if there is a change, it proves that there must be a radiation source in the cave, although the index is still very low, but everyone must pay attention to it.

"It's still within the scope of protection, I'll notify you in time if there's a situation, Thunderbird, I'll go ahead." Tang Xiaobing took a few steps abruptly, walked at the front of the team, and turned on the two tactical searchlights on the shoulders of his combat uniform, which immediately illuminated the dark cave with white flowers.

Because of the protective clothing on their bodies, Zhang Ran and the others moved a little slowly. They didn't know that after the oil deflagration, a devil named Yamaki had come in, and because of the explosion of the laboratory's own device, it was easier for them to cross this path - a large number of obstacles were swept away by the blast wave of the explosion.

"This is the hangar, good fellow, it's a mongoose!" Tang Xiaobing also recognized the wreckage of the helicopter lying on the ground, which was close to falling apart or shattering, this ability was recognized by Zhang Ran, about the fact that there were mongooses in the devil's base, Tang Xiaobing They didn't know in advance, Zhang Ran thought that he changed to Tang Xiaobing's position, and he might not be able to recognize these wreckage at a glance.

"Thrust, yes, there is a future, in the future, the guys who drink oil in our mercenary group will be handed over to you." For Tang Xiaobing's performance, Wuying also showed considerable recognition, and what she said was basically equivalent to Zhang Ran's meaning.

"Hey."

Tang Xiaobing smiled excitedly and said, "Boss, it's strange, it stands to reason that after we come in, the radiation index should change, but the instrument shows that there is basically no fluctuation." ”

"Do you still want the index to go up? Basically, in this case, it is certain that the radiation is not the source of the explosion, but it is only dispersed because of the explosion, and the distribution is relatively even, it seems that we don't have to worry about the problem of radioactive materials, Thunderbird, how is the situation there? ”

What He Quanhui carried on the Thunderbird was mainly a biochemical indicator detector, but what surprised him was that the air quality in the entire cave had reached the standard so far, that is, there were no viruses or chemical weapons remaining.

Could it be that everything is a misunderstanding, and the devils are not doing any anti-human research here?

"Head, come on, there's a corpse here!"

Tang Xiaobing's call made Zhang Ran and the others quickly get closer, and in the wreckage, Tang Xiaobing found a space pressed by a broken wall, perhaps because of the effect of a strong explosion in the cave space, this truncated wall collapsed, but it formed a triangular space.

Because of the protection of the broken wall, this triangular space was not subjected to the impact of the explosion head-on, and what was exposed to the sight of Tang Xiaobing and others was the corpses that Yamaki had seen, the corpses of young women. Although there is the protection of the broken wall, the high temperature is unavoidable, because the corpse that died of lack of oxygen has become a charred corpse at this time, and only the corpse buried at the bottom is basically kept in its original state.

But even if it is coke-like, it can't stump professionals like Zhang Ran and Wuying, just from the proportion of flesh and bones, the two of them can roughly deduce the gender and age of these corpses.

"It's all young women, there is no dust in the mouth, and the body is not deformed by impact, it doesn't look like it was shocked to death."

Zhang Ran nodded, agreeing with Wuying's analysis. He looked at his surroundings and said, "If the air in this cave was directly drained because of the explosion I made, then these women should have died of lack of oxygen, and I killed them." ”

"It's not your fault, I think it's probably certain that the devil is here to conduct some kind of human experiment, either biological or chemical."

"The lab is here, come on!"

He Quanhui was not interested in the discovery of Tang Xiaobing and others, and turned around with a tactical flashlight, and finally discovered the road to the laboratory that Shan Mu had walked. Although after the explosion, this road has been obscured by the wreckage, if it weren't for He Quanhui's careful enough, I'm afraid he wouldn't have found it at all.

Hearing that they had found the laboratory, Zhang Ran and Tang Xiaobing both gave up their observation of those corpses and turned to gather around He Quanhui.

There is only no shadow, but for some reason I always feel a little nostalgic for those charred corpses. It wasn't until Zhang Ran's side exclaimed that she walked over as if she had suddenly come back to her senses.

"What's going on?"

"Shadowless, come and see, is this a fragment of bulletproof glass?"

Zhang Ran's voice sounded in the intercom, and at the same time, he turned around, and in the thick chemical protection gloves, he grabbed a palm-sized glass shard.

"Be careful, don't scratch it, the Thunderbird has already found something."

Wuying stretched out his hand to pick it up, but Zhang Ran retracted it suddenly, this bulletproof glass is different from tempered glass, even if the gloves are thick, if they are accidentally scratched, they will regret it.

After Wuying calmed down and put on a cautious posture, Zhang Ran gave her the glass fragments.

"That's right, high-end goods, Thunderbird, what did you find, the instrument alarmed?"

"No, the instrument still hasn't detected anything, you see, these glasses have dissolved, which proves that the temperature generated at the time of the explosion is very high, this should be the source of the explosion, it turned out to be underground, strange, I'll take a look"

Thunderbird He Quanhui is indeed talented and capable in explosives, and in such a chaotic place, he actually found the room where Shan Mu used to stay, and where the large freezer where those virus stocks were stored.

At this time, this room has long been no longer the original appearance, because the detonator itself is those special battery packs placed in the ground, so the entire ground has been blown up, and the refrigerators placed on the ground naturally flew into the sky in the explosion, even the strongest bulletproof glass cannot remain intact under this level of explosion, and even directly dissolved part of it because of the high temperature.

Even if these freezers made of bulletproof glass are intact, the test tubes stored inside will be shattered, and as for the virus in the test tubes, I believe that under the high temperature, there is only one possibility, that is, it will be completely killed.

"I'm sure this is where the explosion came from." When Thunderbird made this conclusion, Zhang Ran came to a judgment and said: "Everyone searched separately, since the devil detonated here, it proves that this is the place where the light is the most visible, and if there is anything found, it can only be here." ”

The four of them began to look separately, but He Quanhui's attention was still focused on the ground that was blown apart.

He not only turned on the tactical flashlight on his shoulder, but also turned on the camera to record the whole process flawlessly.

Maybe it's a kind of human instinct that is engaged in research, when He Quanhui was searching, Zhang Ran and others could still hear his chatter.

"Judging by the magnitude of the explosion, it doesn't look like an ordinary explosive, but a new type of hybrid material, and there are exposed wires here, which seem too thick if used as a detonation"

"It should be the power supply line to make sense"

"I see!"

Suddenly, He Quanhui became excited, and his roar almost didn't scare anyone.

"Shocked, Thunderbird, are you crazy?"

"Shadowless Leader, you have to forgive this kid, he often does this." Tang Xiaobing said disapprerovingly.

Only Zhang Ran, he didn't have any valuable discoveries so far, so he frowned and asked He Quanhui: "What do you understand?" ”

"Look at these places" Even though he was scolded by Wuying, He Quanhui's excitement was still uncontrollable, and he pointed to some power cords exposed in the corners. The power cords were not preserved under the explosion, but even if they were charred black, they could still be seen to be strong.

"Aren't they just some wires?" muttered Shadowless.

"It's wires, but these wires are never used to detonate explosives, there is no need to use so many wires, such thick wires, they extend from the ground to the walls"

Through He Quanhui's explanation, Zhang Ran and others finally understood that it was not an explosive that exploded, but a battery used to power those freezers.

The battery may explode, and people with a little scientific knowledge know that the news of the explosion of mobile phones or power banks around the world every year is endless, but He Quanhui believes that the devil should have used a special battery here, if it is an ordinary lithium battery, even if it is a lithium battery with the highest capacity level, it is impossible to have such power.

"The devils must have installed a separate explosive, right?" Shadowless asked in disbelief.

"Judging from the situation I have checked so far, there should be none." He Quanhui had inspected the explosion point, and in his opinion, the space where the batteries were stored was still very regular even after the explosion, and there was no additional concentrated explosion point, and if the detonator was used, it would definitely leave special marks on the hard rock surface.

Wuying is not very interested in this kind of purely physical and chemical problem, in contrast, she prefers to discover it by herself, so while Zhang Ran and Tang Xiaobing are listening to He Quanhui's explanation intently, Wuying is still continuing her work.

"I found it, Thunderbird, hurry up and test it with your instrument!"

"What did you find?"

Zhang Ran's reaction was naturally faster than that of the Thunderbird, who was immersed in excitement, and he turned around and came to Wuying's side, and saw what Wuying was holding in his hand.

"Be careful, maybe that's the only valuable gain we've had."
