: 448th Bottomless Hole

With continuous offensives, the middle and lower reaches of the Yangtze River were slowly recaptured by humans. On the other hand, Commander Wu Xiong led his troops to the south from Lu Province, crossing the Huai River smoothly, and gradually linking the liberated areas with Li Yuanhong. .
Although good news came frequently, Li Yuanhong was still worried, and looked at his watch from time to time, as if calculating what time. Finally in September, before the portal was about to open, Li Yuanhong disappeared again.
On the second day of Li Yuanhong’s disappearance, several airships flew over to Siberia. At this time, China was still in the late autumn season, and many places were still blooming with willows and greens, which was completely vibrant. But at this time, Siberia had already had several games. It's snowing, and in many places, the green has no meaning.
Li Yuanhong came here at this time not to travel, but to find a base, the base of the subterranean tribe. There, there is a portal that is about to open. Li Yuanhong wants to experiment with this portal to see the original Naga. How to use the crystal that the female curator gave to herself.
To close this portal, Li Yuanhong must go deep into the territory of the cavemen. If he is not careful, he will be discovered by the cavemen. When these cavemen give themselves a urn to catch turtles, they can't eat them.
The reason why Li Yuanhong chose the cavemen to start was mainly because he had dealt with these cavemen many times and knew about their various attributes, and he had pitted them several times, causing these blind men to suffer heavy losses. That wave of aliens is the weakest, these cave people. Of course, Li Yuanhong would not be careless because of this.
Those who came with Li Yuanhong this time were all system soldiers. Li Yuanhong did not bring a human. This kind of thing was too dangerous and involved many private matters, so Li Yuanhong did not bring anyone.
Walking down the mine, the cave stretches downwards. It used to be a cave in the Soviet era. It seemed that the Soviet Union was studying the center of the earth, but it stopped after hitting more than 10,000 meters. According to some rumors, they It seemed that they saw the gate of and saw the evil spirits. In order to prevent the demons from coming to the earth through the portal, they had to blow up the lowest level and stopped further digging.
But according to the news that Li Yuanhong got from Naga, it was just a coincidence that these big noses dug into the portals of the alien world. At the beginning, the energy of the portal was insufficient, and only some low-level wild animals and creatures with low-level soul states in the alien world Send it over. However, these strange beasts are also stronger than the creatures on the earth, and those scientists who are doing scientific research are almost wiped out by a single face.
Fortunately, the Soviet Union had a strong military capability at the beginning. Later, it sent many special forces and used many super-tech weapons at that time to destroy these alien creatures. If the energy of the portal was enough at the beginning, it would send a level 4 minotaur or something. A dozen Medusas will come, and it is estimated that half of the Soviet Union will be wiped out.
Li Yuanhong went down the tunnel. There was originally an elevator going straight to the bottom, but since the tunnel was abandoned, the elevator has been out of electricity. Fortunately, when the mine was excavated, the elevator was out of order, so he was around the elevator. , Dug a circle of circling passages.
Li Yuanhong is walking through this channel now. The passage was very dark, and Li Yuanhong was forced to light a torch and walk in the dark and silent passage. After a long time, it was easy to make people feel mentally depressed. The threat to Li Yuanhong was not an enemy attack, not darkness, but the possibility of taking it at any time. Facing the tunnel collapse.
This tunnel was excavated more than half a century ago. Although the wood used for the support is high-quality wood, many of the wood has been decayed due to the invasion of time. Li Yuanhong accidentally touched a piece of pillar wood, and the wood was immediately shattered. , Until now, Li Yuanhong didn't know when this tunnel would collapse.
Li Yuanhong walked down the tunnel for two hours without reaching the bottom. Fortunately, he came to a platform. It was a large area with many equipment left, but it was also rusty.
"Everyone, take a break and be alert!" Li Yuanhong looked at the platform and found that there were traces of crawling by unknown animals, and many luminous plants grew around it.
Li Yuanhong took out the water bottle and took a sip. In order to fight, Li Yuanhong must always stay vigorous. Li Yuanhong looked at his watch. He estimated that it was three to four kilometers deep from the ground. If it is on flat ground, it would take only ten minutes to walk three to four kilometers, but the underground tunnels would go around and take time. Be vigilant, so the speed is naturally not up.
When Li Yuanhong was thinking about how to go next, he suddenly felt that something fell on his head. Li Yuanhong immediately raised his head and looked up. It was okay not to look at it, and he was shocked.
I saw that the top of the cave was full of bats. These bats were the size of a washbasin, and these bats turned out to have red eyes. Li Yuanhong quickly opened the real eye to check the state of these bats:"
Mutant carnivorous bat
Level: Level 28
Variant carnivorous bats evolved from insectivorous bats. Due to their larger size, stronger strength, and weaker insects, they can no longer satisfy the bat’s appetite. Therefore, carnivorous bats began to appear carnivorous, and any creatures that appeared within their hunting range , Will be attacked by him.
Skills: sonic detection, resonance, ghost attack
Sound wave detection: The bat’s own skills can accurately locate the opponent no matter where the opponent is.
Resonance: By emitting sound waves at the same frequency as the opponent's brain, it interferes with the opponent's actions and even makes the opponent lose resistance.
Ghost attack: The bat is a ghost in the dark. He can melt into the darkness through his own skin changes, so as to silently attack the opponent and make a fatal blow.
Weaknesses: Bats rely on sound to attack and locate. Similarly, once his sound waves are disturbed, he will become blind and deaf, and even flying will be difficult. "
As soon as Li Yuanhong finished reading the introduction of the bat, he saw that the bats that were hanging on the ceiling of the cave suddenly spread their wings and flew up. With these bats taking off, Li Yuanhong immediately felt that his head was attacked by something. A little bit painful.
"All members are on guard, shields defend, archers and wizards attack these bats!" Li Yuanhong endured the pain in his head, ran under the shield, and gave orders to the soldiers.
The system soldiers acted immediately. These soldiers have already rehearsed for various emergencies. For this situation, there have been plans for this situation, but the sonic attacks of these bats slowed the soldiers' movements. The wizards and archers' Most of the attacks failed. Even if some attacks hit these ghosts in the sky, they would have little effect on thousands of bats.
At the same time that Li Yuanhong ordered to attack the bats in the sky, the bats also began to attack the humans on the ground. The shields of the Shield Soldiers were dinged by the bats, and the impact of these bats was very strong. If the Shield Soldiers were not standing on the ground. As the bats hit from top to bottom, these soldiers had to retreat again and again. Even so, the sword and shield soldiers could only support themselves, holding their shields to resist the impact of these bats, and could not fight back.
And these bats are also good at sneak attacks. Several soldiers standing on the edge of the team were bitten into the gaps in the armor by the bats, and their muscles were torn apart. Some soldiers were even torn away a large piece of meat, and blood flowed out.
The air dissipated, which stimulated the bat even more, so these ghosts in the air were even more frantically looking for an object to start, preparing to bite off a piece of meat to fill their stomachs.
As time went by, the screams of the soldiers around became more and more, more and more people were injured, and some bats even began to rush into the center of the team to attack. However, the human attack has never been effective. , I'm afraid everyone will explain here.
Li Yuanhong quickly thought about coping strategies and began to look at the things in the space. When Li Yuanhong saw the flame grenade, he suddenly thought of a question. These bats can avoid a single magic or bow and arrow attack, can they avoid a large area attack?
Li Yuanhong didn't think too much, took out the flame grenade, opened the lead, waited for two seconds, and threw it directly to the top of the cave.
Seeing something attacking from below, the bat easily avoided it. For this kind of large-target and slow attack, the bat didn't care at all. If they couldn't avoid this kind of attack, they would have been extinct.
The grenade did not touch any bats, directly hit the top of the cave, then bounced back and began to fall towards the ground. When it fell back two or three meters from the ground, the grenade exploded. Although the flame grenade exploded, the damage was not great. But a group of flames spread directly to the outside. Those bats near the grenade did not expect this round and strange creature to spew fire. For a time, a three-meter-square bat was directly lit by the flame. There were more than a dozen bats. They turned into fire bats in an instant, and these bats made "squeak" noises, fell down, and there was no movement in a while.
"Use a group of large-scale magic attacks!" Seeing that the grenade was effective, Li Yuanhong quickly ordered the opponent's magician.
As magicians began to use a wide range of magic, the bats that had just ruled the king suddenly screamed, all kinds of "squeaking" sounds, one after another, but they can't easily avoid attacks when they are there, and they can't easily dodge the attack. Magic made it impossible for them to judge the point of magical attack. In less than a minute, hundreds of bats were killed.
Although large-scale magic is effective, it consumes too much energy to cast. In just one minute, many magicians consume more than half of the magic energy. If it continues, the bats are not wiped out, the magic value of the magicians will be Depleted.
At this time, there are still a huge number of bats flying at the top of the cave. Six to seven hundred bats are still in the air ready to sneak attacks. As the number of bats decreases, the density of bats also decreases. The attack effect of the magician’s spells, Not as effective as before.
