Long before the colorful light curtain in the basement disappeared, Bai Buwei cultivated to the peak realm of the early stage of foundation building in the secret room of the other world, and was only a line away from breaking through to the middle stage of foundation building.

After the disappearance of the colorful light curtain, due to the transfer of a large number of spirit stones from the underground spiritual veins of the other world, so that there was no shortage of spiritual energy supply when cultivating, Bai Buwei would insist on cultivating almost every night, even if he did not use spirit stones to provide spiritual energy cultivation during the special training period, he also tried to absorb thin spiritual energy from the air for cultivation.

After cultivating like this, when the Vajra Immortal Divine Skill broke through to the Zhongcheng realm, the Great Yan Dao Technique and the Great Yan Refining Divine Determination both made breakthroughs.

The breakthrough of self-cultivation to the middle stage of foundation building not only increased by nearly half of the spiritual power group, but also absorbed the spiritual energy faster, which in turn made the spiritual liquid accumulation in the qi sea more abundant, and the divine sense was also strengthened a lot, and it was able to detect movements twenty miles away.

Compared with Bai Buwei's progress, satisfaction with university life, and smooth part-time work, which makes him happy, the state security department and the personnel of the Abnormal Ability Bureau in Anping City are not in a good mood.

Since the end of August, with the help of the mysterious master, that is, Bai Buwei, Liu Gang and other personnel of the Ability Bureau have captured the Great Elder of the Heavenly Fire God Sect, the Second Elder and a number of other evil ability personnel in one fell swoop in the depths of Daheng Mountain, causing the number of evil ability personnel in Anping City to shrink sharply and decrease, and the entire Anping City has also become much more stable.

After interrogating the Great Elder, Second Elder of the Heavenly Fire God Sect, and other cadres, the Anping Ability Bureau successfully found several dens of evil dao organizations, but unfortunately the building had already been emptied, and the results of the battle were not further expanded, as for Huang Hu, the leader of the Heavenly Fire God Sect, he did not have any information, and he did not know where he was or what he looked like.

The Anping Abnormal Ability Bureau will not easily let go of this group of evil organizations that seriously threaten social stability, and continue to devote great energy to paying attention to abnormal events in Anping City and even the surrounding areas, hoping to discover the lair of the evil organization, and finally catch the mastermind Huang Hu.

It's just that after learning that the Great Elder and the Second Elder of the Sect were arrested, Huang Hu, who was cautious by nature, promptly issued an order for all the people in the Sect to stop all destructive activities, mainly to hide themselves, and at the same time find a way to find out the origin of the mysterious master, so the actions of the Anping Ability Bureau were nothing.

If the abnormal personnel of the evil organization do not come out to make trouble, the Anping Abnormal Ability Bureau has no way to investigate, and gradually shifts the focus of its work to continue to search for mutated animals and plants, and the search for these mutated animals and plants is not only used to study and extract spiritual energy-related substances, but also to prevent trouble.

Fortunately, mutated plants that contain aura and can independently gather aura, except for some plants that can emit poisonous gas, are basically not dangerous at present, and most of them grow in the deep mountains and old forests, and will not take the initiative to destroy the harmony of human society.

Those mutated animals containing aura are different, most of them have a certain lethality, and can move freely, and continue to grow in strength, maybe that day will come out to destroy the environment of social stability and development, it is necessary to take advantage of their weak hours to remove hidden dangers in advance.

At the end of early October, Liu Gang and other personnel of the Anping Abnormal Energy Bureau went deep into the depths of Daheng Mountain to search for mutated animals and plants as usual, and the aura detector found that there was an abnormal situation of aura in an underground cave, showing that the aura content was much higher than the normal value.

So, Liu Gang and the others prepared all the lighting facilities and protection to go down to the cave to find out, but they didn't expect to find any mutated plants or other natural treasures containing aura, but they encountered a group of bats.

What is even more unexpected and terrifying is that there are many mutant bats in this group of bats, not only flying fast and acting quickly, but also emitting ultrasound waves that can affect the mental condition of the brain, which will produce a sense of fainting.

Although Liu Gang and other personnel of the Anping Ability Bureau were not ordinary people and did not faint due to the attack of sound waves, many people felt uncomfortable, which in turn affected their speed and agility.

The attack of the mutant bats was not just a sonic attack, as the sound waves were emitted, many mutant bats quickly approached some of the Anping Ability Bureau personnel, opened their mouths and teeth to bite the exposed necks of these personnel, and actually sucked blood.

Under the influence of a variety of factors, many Anping Abnormal Ability Bureau personnel were bitten by mutant bats on their necks and sucked a lot of blood, and at the same time, the wounds were sore and numb, and their brains became more and more drowsy, obviously the mouth teeth of mutant bats contained highly poisonous.

The personnel of the Anping Ability Bureau, who were dazed by the stroke, first let out a cry of pain, and then continued to grab the vampire bat nailed to the neck with both hands, and those with slightly stronger willpower and not weak willpower successfully grabbed the vampire bat with a piece of flesh and blood on their necks, while those with slightly weaker willpower were powerless to resist the vampire bats and gradually fainted to the ground.

Liu Gang and other personnel of the Ability Bureau who were not recruited hurriedly shot the flying bats or drove them away with other objects, while stepping forward to help the fainted companions drive away the vampire bats, and dragged the fainted people back and continued to retreat out of the underground cave.

Vampire bats fly too fast and are too agile for bullets to hit, and other items such as portable daggers can only drive away, making it difficult to kill.

Therefore, after all the personnel withdrew from the underground cave, they did not kill many vampire bats, at most some ordinary bats, and those vampire bats did not stop because of this, chased out of the underground cave, and continued to attack.

Liu Gang and other uninjured people had no choice but to gather the injured and fainted people together, and surround them outside to defend or attack the vampire bats, perhaps because of the light, or maybe the attack was fruitless, and the vampire bats that chased them quickly gave up the attack and returned to the underground cave.

A group of people waited for this to relax, and hurriedly arranged for people to be vigilant around while checking the injuries of the fainted people, and their fainted people were all black, the flesh and blood on their necks were eroding, the blood flowing out was black, and their breathing was weak, even if they were in a coma, they were trembling.

After a little inspection, it was found that the existing conditions could not be treated, Liu Gang commanded the people to fill a bottle of energy liquid for one of the unconscious team members, and then urgently asked the bureau for help to arrange an ambulance, and the uninjured people carried these unconscious team members out of the mountain.

Liu Gang and other uninjured people carried their unconscious teammates on their backs and ran as fast as they could, and soon after they sent these unconscious teammates to an ambulance that rushed to the vicinity of Daheng Mountain, and it is unknown whether these unconscious teammates can be successfully treated.

However, the toxicity of vampire bats is far beyond imagination, although the physical fitness and willpower of these people are far beyond ordinary people, but they still can't withstand the poison attack, and five people with abilities died of poison on the way to the hospital, and several other comatose people are temporarily out of danger after being rescued by doctors, but there is no sign of waking up.

In any case, after this toss, the morale of the personnel of the Anping Ability Bureau has dropped a lot, most of them are worried about the safety of their teammates' lives, and they also have hatred and vigilance for the vampire bats in the underground cave.

If one day these vampire bats fly to the surrounding area and harm ordinary people, it will be quite dangerous, and it is imperative to find a way to wipe out the bat swarm in the underground cave.

After receiving Liu Gang's report, the director of the Anping Abnormal Energy Bureau was heartbroken, and immediately made arrangements for Liu Gang to lead all the personnel of the Abnormal Ability Bureau to Dahengshan again with special steel nets, incendiary bombs, shock bombs, grenades and other weapons.

The instructions were to capture a few vampire bats and hand them over to professionals for research on their own safety, so as to develop an antidote to the toxin, and make sure to wipe out the bat colonies in the underground cavern.

Liu Gang led a group of intact personnel of the Abnormal Ability Bureau to the underground cave again, did not dare to enter the cave easily, and used the instrument to detect any signs in the underground cave, confirmed that the bats had not left, and carefully checked whether there was any abnormal situation around.

After everything is ready, a number of incendiary bombs and shock bombs are thrown into the underground cave, and then people are arranged to spread the net at the entrance of the cave.

A moment later, there was a loud rumbling sound from the underground cave, which shook the surrounding mountains and forests a few times, startled several birds and birds and many wild animals to flee, and then, from the mouth of the cave, there was a sonic attack, followed by bats rushing out.

As early as when throwing down the incendiary bombs and shock bombs, Liu Gang reminded Zhang Wang's guards at the entrance of the cave to be vigilant, so although the many bats that rushed out were caught by special steel nets one by one, although they had a lot of impact.

These netted bats, ranging from normal bats to mutated vampire bats, all opened their sharp beaks and bared their sharp teeth to make unpleasant screams, and bit hard at the steel net, trying to break through the net.

It's a pity that the several members of the Ability Bureau who are guarding the cave entrance and opening the net have high strength and strong willpower, and the sound waves emitted by the mutant bats have a limited impact on the spirit, which is enough to have time to catch the bats that rush out.

Seeing that there were no bats rushing out again, and twenty or thirty bats had been caught in the steel net, Liu Gang came down, changed the steel net, and let a few team members hold it at the entrance of the cave, and then continued to throw incendiary bombs and shock bombs into the underground cave.

After doing this several times, fewer and fewer bats rushed out of the underground cave, and as long as there was no movement for a long time, the step of throwing bombs and spreading the net was over.

Although there seemed to be no movement in the underground cave, and no signs of life could be detected by the instrument, which meant that there might be no live bats in the underground cave, Liu Gang and others were still not at ease, and ordered some weaker team members to continue to spread their nets to guard the entrance of the cave.

Liu Gang led a number of powerful team members to prepare for the necessary defense and attack, and carefully entered the underground cave with lighting equipment to search and check.

The group soon entered the depths of the cave, and found many bats that fell to the ground along the way, and collected them one by one and packed them in special bags, and the deeper they went into the cave, the more bat corpses they picked up.
