The Hero Who Troubles the Heroes

When the morning sun was rising in the east, small black dots flew from a distance, and these black dots became more and more, and finally gathered into a dark cloud.

Countless vampire bats are flying back to this habitat from all directions, circling out of the mountainside openings, and then flying into the holes in an orderly manner.

On another mountain more than 300 meters away from the cave, Charles frowned while watching the cave while eating breakfast. Things were a little unexpected to him.

When he came, he discovered that the entrance of the cave was about 70 meters high and 60 meters wide.

Assuming that a vampire bat hangs upside down on the roof of the cave needs a space of 20×20 cm, then 25 bats can be hung in one square meter.

Assuming that the area of ​​the top of the cave is 60×100m, there are at least 150,000 bats in it.

Judging from the vampire bat he caught last night, a vampire bat weighs about 600 grams. If each bat consumes a body weight of blood every night, they will **** at least 30 tons of blood in one night. .

Calculated based on the 20-kilometer radius of activity of the vampire bats in one night, the animals in the surrounding more than 100 square kilometers will be finished soon.

This was a bit beyond Charles's expectations. The fact sheet given by the principal was unclear. At first, he thought that the cave was only 30 to 40 meters high and wide, so that it could at least be cleaned up with rockets.

Now this cave has too much space, too many bats, and not enough rockets. Moreover, after using long-distance attack methods such as "Treasure of Yi", pea shooters, and corn cannons to startle the bat swarm, the bats that burst out instantly are very large. It may exceed the firepower projection intensity. After the bat in front blocks the attack, the bat in the back will break through the defense line.

Maybe it's impossible to kill all the vampire bats at once, and their escape will harm other places.

Charles thought about it for a while, let's work out a miracle.

In the battle to capture the undead at the space gate, he once cast a wall of fire that was tens of meters long, ten meters wide and several meters high. This wall composed of extremely pure fire elements instantly set a team of necromancers on fire. into ashes.

Here, the wall of fire can be flattened to a height of 70 meters, a width of 60 meters, and a thickness of half a meter. Sweeping over it can block and burn these vampire bats to death, and by the way, the cave can be disinfected.

He remembered that bats carry a large amount of bacteria and viruses. If they are not properly disinfected, they may become a source of disease infection.

So he put on the protective suit again, put the oxygen cylinder on his back, and then teleported to the bat cave.

He opened the "Soul Sight", and the dense bats were connected on the interface.

At this time, another moth appeared, and a string of light spots appeared behind him on the interface. Looking back, a large team of nearly 100 people was walking towards this side from a distance.

Mosquito legs are also meat, and the experience points of vampire bats are also experience points. Besides, the number of hundreds of thousands should be enough for him to rise to level 51.

Since Chapter 903, he burned his soul with chaos in chaos and sublimated his soul, and his strength has been further improved. Although the number of levels has not changed, it has changed from blue to purple, and has stepped up a step.

Now that he has leveled up, the strength of his body's feedback is extremely impressive.

But this kind of thing is personal privacy, will not tell others.

Now someone comes to grab experience, that is naturally not allowed.

Quick hands, slow hands, Charles immediately began to use magic.

There are a lot of wind and water elements around the cave, as well as some earth elements, and there are a large number of basic elements that only a few people can feel.

The foul mental power spread out, and the mental power grabbed the basic elements one by one, and then affected them, making them into extremely pure fire elements.

A few hundred meters away, the crusade team consisting of knights and soldiers in the castle led by the brave and his partners suddenly stopped, and a fiery red fire element suddenly appeared outside the entrance of the cave, which shocked them.

These fire elements quickly gathered together to form a wall of fire that was as crystal clear as gems, blocking the entrance of the cave.

White smoke began to rise from the area around the cave in contact with the fire wall, and the limestone that formed the mountain was heated and decomposed to release a large amount of carbon dioxide, and the resulting quicklime was rushing down.

The plants on the side were also dried in an instant, and then burned.

Charles could feel that the vampire bats at the entrance of the cave had already felt bad, they were so frightened that they flew around, and the sound of their arms flapping could be heard behind the fire wall.

He began to manipulate the half-meter-thick wall of fire to push into the depths of the cave at a speed of five centimeters per second, ensuring that every place in the cave was sterilized by high temperature for ten seconds.

Those vampire bats that were shocked by the heat flew around, and they lost their calmness in the past, and many bats collided in the air.

It didn't take long for Charles to see piles of gray-white ashes appearing on the ground, which were the ashes of the vampire bats that had fallen on the ground.

Not long after, the quicklime on the top and sides of the cave began to fall down, and the cave was instantly white.

The wall of fire moved forward slowly and firmly, and countless vampire bats flew towards the depths of the cave, but there was a dead end.

Charles' consumption is very large~www.readwn.com~, but under the recovery of the "Battlefield Perpetual Motion Machine", he consumes and replenishes, and the consumption is definitely within an acceptable range.

The cave warrior rushed over with his partner, and stared at the white cave outside the cave entrance in a stunned manner. The hot air rushed towards him, and he didn't know whether to advance or retreat for a while.

Charles ignored them and went about his business.

At this moment, a vampire bat king with a wingspan of ten meters rushed out from the depths of the cave, its body exuding blood-red light.

It realized that it had to escape today, so it sucked the blood of many of the same species around it, accumulated energy, and tried to break through the deadly wall of fire.

Charles didn't find it, because the density of bats here is so high that the souls of ordinary bats cover up its existence.

It's just that the Vampire Bat King underestimated the temperature of the wall of fire, and the people on the other side of the wall only saw a flame fly out of the wall, and then fell to the ground, burning alone.

Charles continued to move forward slowly, and the crystal clear wall of fire continued to burn up every space until the end of the cave.

At the end of the cave there is a channel leading to the depths, a few meters wide.

Charles dissipated the wall of fire and burrowed in.

A dozen or so vampire bats also got in, and they were killed with fireballs by Charles, who was chasing in.

In the depths of the cave is an underground river, pitch-black, and I don't know where it leads.

He took out the lamp and looked around, then found a row of steps on the bank of the underground river leading to the upper reaches of the underground river.

These steps carved out of the rock look like no one has gone for a long time, and some stalactites have been erected on them.

He walked down the steps without hesitation.
