The miserable bones hung above their heads, and Captain Jiang and Professor Zhang glanced at each other, both seeing their doubts and anxieties.

Who are these people? Where did they come from? Why did they come here? How did they get in? Did it have anything to do with their scientific expedition or did they meet by chance? What happened to them?

They don't know anything.

The water in this mysterious dungeon hidden in the belly of Kunlun Mountain is really deep.

Under the guidance of Professor Zhang, Chang Sha used his dexterous ape-like skills to carefully investigate the surroundings up and down the stone steps, and found that a hole appeared under the stone steps not far ahead, which was quite secret, and it was easy to miss it if he did not look carefully.

"Well, these people must have come out of this hole, and they encountered some danger inside, but they didn't expect to encounter a swarm of bats just after escaping. Captain Jiang carefully investigated the situation at the scene and said slowly.

Professor Zhang carefully observed several corpses and found that not only were they not all corpses, but also the same as Fang Cai's helmet, the mutilated parts were very neatly notched, as if they had been cut directly by a large pair of scissors.

Captain Jiang was analyzing that this group of people obviously did not encounter an accident suddenly, but retreated and fled here after being in distress, desperately climbing up, and it was the smell of blood that attracted a swarm of bats and were eaten when they were on the verge of death.

What happened to them? Obviously, that thing was not a mechanism, it would chase and kill, but why were these people so scared that they were desperately trying to climb up until they died.

Everyone untied the safety rope, managed to put down a close and complete corpse, took off the helmet and combat uniform, and halfway Tang Chunjiao endured nausea and a few nails to kill a few bats that flew out.

After searching for a while, there was nothing to gain, Captain Jiang said that it was also reasonable, this level of military personnel went out to perform tasks unless the task required it was impossible to carry objects that could prove their identity, and the action plan was also kept in mind, Professor Zhang judged that the deceased was of Western race according to bone thickness, bone density, epiphyseal healing status and other bone characteristics, middle-aged men between forty and fifty years old, with many old bone injuries, and of course more new injuries.

Originally, this kind of living military doctor Mao Jingqin was the most professional, but Professor Zhang was grateful and cherished, and took the initiative to take the job of a cameo forensic doctor.

Everyone was ready to continue on the road with a stomach full of questions, and now including Professor Zhang, he has no intention of exploring the underground palace anymore, he just wants to take the team out safely, and then immediately contact the central government to ask the army to intervene.

Mao Jingqin suddenly said "ah", everyone hurriedly asked what was wrong, Mao Jingqin waved his hand and said it was okay, but his hand cut a small hole, and he might have touched something sharp.

As soon as everyone breathed a sigh of relief, Professor Zhang yelled "not good", and at the same time, the team members heard the sound of wind and flapping wings in the distance.

Everyone also knows that bats not only rely on their sense of hearing to become the king of the night, but their sense of smell is not low, but they can't imagine that just such a small opening from such a distance is enough to attract a rioting bat swarm.

Soon a flying cloud poured out of the darkness into the searchlight, and the scene was terrifying, and the sight of them fishing was terrifying enough, and now the prey was changed to themselves.

Professor Zhang used the sonic ball again, but this time it didn't work wonderfully, and the bats were still in turmoil, and it was clear that the bloodthirsty primordial jade hope had overwhelmed their sanity.

The gunfire was loud, and he didn't wait for Captain Jiang to give his order

Two modified Type 95 5.8mm automatic rifles were fired, followed by the sound of Type 05 submachine guns mixed with pistols.

The scientific expedition team is equipped with not many weapons, only three Chinese Army housekeeping skills 95 and one special forces QCW05 submachine gun, which is naturally in charge of Captain Jiang and several Chinese Army soldiers, in addition to the military doctor Mao Jingqin and Professor Zhang are also equipped with an exclusive pistol as a self-defense weapon for wild adventures and encounters with dangerous wild animals, which shows that the safety of the scientific expedition team is still more important.

In this case, submachine guns and grenades are better than Type 95, the former has a faster rate of fire, and the latter explodes a piece, but they don't have grenades at all, after all, this is a scientific expedition and not a war, and the imaginary enemy of the weapon is the brown bear and the wolf, and no one will use a machine gun to fight mosquitoes, and although the rate of fire of the submachine gun is higher, but the range is not enough, at this time the soldiers subconsciously chose a more comfortable rifle, and wanted to keep these "blessings" away from them, don't bring them "blessings".

The rate of fire under the full firepower of Type 95 is still okay, Chang Sha and Mo Daonan are both first-class sharpshooters, and they can accurately hit the guns without fail, but after all, this is thousands of carnivorous bats, even if their firepower net can be blocked by full firepower, the amount of ammunition they carry is not allowed.

The safety rope has been untied, and the expedition team is fighting and retreating, the situation is very unfavorable, this is an open cliff that cannot reach the world, and if they cannot find a suitable shelter or expel the bat swarm before they run out of bullets, they will die.

But the bats have been beaten like chickens, and they don't know what fear is, and the death of their own kind has only inspired them to become more crazy beastial.

"Batsuit!!" Professor Zhang yelled.

The team members were stunned for a moment, the batsuit is a relatively difficult to control short-distance gliding tool, used to cross some deep valley terrain that is not wide, but what is the use now, can the batsuit fly better than a real bat?

"Down, the hole!" roared Captain Jiang.

The team members woke up like a dream, they are now facing the same situation as these brothers, but these brothers would rather be eaten alive than climb up rather than retreat into the hole and think about it with their toes, knowing that there is a big horror inside, but the scientific expedition team has not encountered it, and now retreating to the cave is the best choice, as for what will happen next, you have to live in front of you first.

The team members used the bat's suit to glide to the entrance of the cave in an orderly manner, which is only more than ten meters away from the entrance of the cave, there is no problem with the training level of the scientific expedition team, Captain Jiang and several other soldiers adhered to the practice of the people's army, Chang Sha took the submachine gun handed over by Captain Jiang and handed over the 95 type to the instructor to complete the exchange of fire points and change guns, and then grabbed Mao Jingqin and jumped together, stretched his limbs in the air, and the small bionic membrane wings made of high-strength military materials were deployed, and with the help of the power of the air flow, he borrowed a force out of thin air and glided towards the hole, and Professor Zhang and others, who had arrived first, responded at the entrance of the cave。

Unexpectedly, Mao Jingqin's bat suit seemed to have a problem, Chang Sha felt that she was obviously falling too fast, so she was so anxious that she threw the submachine gun into the hole, and stretched out a hand to grab Mao Jingqin's hand, but it was empty.

The entrance of the cave was not big or small, and only one and a half people could stand, and Tashi, who was standing at the entrance of the cave, didn't look at the submachine gun, only stretched out his hand, anxiously hoping to catch his teammate's hand, when he saw Mao Jingqin falling

He almost wanted to take a few steps to catch it, but fortunately, Tang Chunjiao behind him grabbed him so that he didn't let him step into the abyss.

"Mao Jingqin!" Tashi exclaimed urgently.

He finally grabbed Chang Sha's hand, but Mao Jingqin's hand, it seemed impossible for him to catch it.

A roll of the long rope wrapped around Mao Jingqin's waist, it turned out that Master Yasi made a move, and in his eagerness, he subconsciously wanted to throw out the long rope, but soon realized that the length was not enough, and immediately threw out the safety rope, and finally staged a scene of "last second salvation" at the last moment.

However, just as everyone was about to pull Mao Jingqin back, the bats rushed over desperately, and they had already noticed the hole.

Tashi quickly picked up the submachine gun and fired, clearing the obstacle for pulling Mao Jingqin back, Tang Chunjiao's flying weapon danced with bullets, blooming blood flowers in these dangerous black wings, but she was not helping Tashi cover, but covering Mao Jingqin.

The bats swarm pounced on Mao Jingqin like crazy, and for a while they didn't even care about Captain Jiang and Mo Daonan, who were still in the back of the break, until this time everyone realized that the crazy bat swarm seemed to only pay attention to Mao Jingqin from beginning to end, to be precise, Mao Jingqin's bloody hand.

Mao Jingqin grabbed the safety rope with one hand, and the bleeding hand quickly wrapped two circles in the bandage with one hand, but it was too late, the bats that surrounded the inside and outside three times rushed up with red eyes, Mao Jingqin was a girl after all, it was the first time she was so close to these creatures, so close that almost as soon as she inhaled, it was their exhaled breath, and she didn't faint when she really Liu Hulan Qiujin was alive.

A few bats that pounced on her were about to catch her face, but fortunately, Mo Daonan smashed the few around her cheeks to pieces with a single shot.

The situation was extremely dangerous, the team was scattered into three points and surrounded by the bat swarm, Mao Jingqin almost became a meal on the plate, and if Mao Jingqin was not pulled, the broken Captain Jiang and Mo Daonan would not be able to fly back to the crowded cave to meet, but the bat swarm attacked Mao Jingqin like crazy, and they didn't even care about the attacks on both sides, and they were invisibly hit by "attacking the middle road, so that their heads and tails could not be connected" 's art of war and tactics, Tashi Tang Chunjiao, who was standing at the entrance of the cave, could only barely cover to protect Mao Jingqin, and Master Zhang, who was behind him, slowly pulled back the safety rope.

More and more bats were pressed up, and the pressure on the expedition team was increasing, and the situation was stalemate for a while.

What to do?

Professor Zhang's mind was spinning rapidly, and one plan after another was quickly established and overturned in his mind, when a backpack was thrown up, which was Mao Jingqin's medical bag.

There was only one circumstance in which the military physician would give up the medical kit, did she want to......

"Don't, Sister Mao!!" Tang Chunjiao roared in a crushed voice.

Sure enough, Mao Jingqin untied the safety rope that kept her life, and at the moment of falling, she also unwrapped the bandage she had just wrapped.

Then everyone saw that the female military doctor, who had always been gentle and intellectual, fell into the endless darkness like a real angel with broken wings, without rhetoric, without last words, this girl was so gentle and intellectual, even being a martyr, countless creatures with black wings were attracted by the smell of blood and rushed greedily.

"Mao Jingqin!!" Professor Zhang shouted with all his might.
