The Troublesome Hero Among the Heroes

When the morning sun rises in the east, small black spots fly in from a distance. These black spots are getting more and more, and finally they gather into a cloud of dark clouds.

Countless vampire bats are flying back to this habitat from all directions. They circle outside the cave entrance on the mountainside, and then fly into the cave in an orderly manner.

On another mountain more than three hundred meters outside the cave, Charles was eating breakfast while frowned watching the cave. Things were a bit unexpected.

Only when he came, he discovered that the mouth of the cave was about 70 meters high and about 60 meters wide. It stretched slowly into the mountain for a hundred meters like a bell mouth, and then quickly shrunk.

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

Assume that the area at the top of the cave is 60×100m, and there are at least 150,000 densely packed bats.

Judging from the vampire bat he caught last night, a vampire bat weighs about 600 grams. If each bat sucks blood of about ⅓ of its body every night, they can At least 30 tons of blood must be sucked.

According to the calculation of the vampire bat's activity radius of 20 kilometers in one night, the animals in the surrounding area of ​​more than 100 square kilometers will be finished in a short time. It will be sooner or later that they enter the villages and towns to attack humans as they did last night. thing.

This is a bit beyond Charles’s expectation. The Principal’s description of the situation is not clear. He at first thought the cave was only 30 to 40 meters high and wide, so that it could at least be used with rockets. tidy.

Now this cave is too big, there are too many bats, and there are not enough rockets, and the long-range attack methods such as "Treasure of the Lun", the pea shooter, and the corn cannon are used to start the bat group. , The bats that burst out in an instant are likely to exceed the firepower projection intensity. After the bats in the front block the attack, the bats in the back will break through the line of defense.

Maybe it's impossible to kill all vampire bats at once, they will harm other places if they escape.

Charles thought for a while, let's do a miracle vigorously.

In the battle to capture the dead at Space Gate, he once cast a fire wall tens of meters long, ten meters wide, and several meters high. This extremely pure Fire Element wall instantly A group of undead Knights burned to 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 through the past can block these vampire bats and burn them to death. By the way, the cave can be disinfected.

He remembers that bats carry a large number of bacteria and viruses. If they are not properly disinfected, they might be another source of disease infection.

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

He opened the "Soul Vision", densely packed bats are connected together on the interface.

At this time, a moth appeared again, and a string of light spots appeared behind him on the interface. Looking back, a battallion team of nearly a hundred people was walking towards this side.

The legs of mosquitoes are also meat, and the EXP of the vampire bat is also EXP, and the number of hundreds of thousands should be enough for him to reach Level 51.

Since Chapter 903, after burning the soul with the chaos and sublimating the soul, his strength has been further improved. Although the number of levels has not changed, it has changed from blue to purple. Up a step.

Now that he has been promoted to Level 1, the power of his body to get back feed is extremely impressive.

But this kind of thing is personal privacy and will not be told to others.

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

Hands are fast and slow, and Charles immediately starts to use magic.

There are a large number of Wind Element and Water Element around the cave, as well as some Earth Element. In addition, it is the basic element that a large number of people can only feel.

The spirit strength, which is too strong to violate the rules, spread out, and the spirit strength grasped the basic elements one by one, and then affected them, making them become extremely pure Fire Elements.

Besides several hundred meters, the crusade team composed of Knight and soldiers in the castle led by hero and his partners suddenly stopped, and a fiery red Fire Element suddenly appeared outside the cave, giving them to Shocked.

These Fire Elements quickly gathered together to form a gem-like crystal clear and near-transparent fire wall, blocking the entrance of the cave.

White smoke began to rise from the place where the cave was in contact with the wall of fire. The limestone that made up the mountain was decomposed to release a large amount of carbon dioxide, and the generated quicklime was falling down.

The plants on the side were also dried instantly, and then burned.

Charles could feel that the vampire bats at the entrance of the cave felt bad. They were so startled that they were flying around, and the sound of their arms could be heard behind the wall of fire.

He began to manipulate the half-meter-thick fire wall to advance to 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 startled by the heat flew around, no longer the calmness of the past, many bats collided in the air.

It didn't take long for Charles to see piles of ash-gray ashes on the ground, which were burnt by vampire bats that fell on the ground.

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

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

Charles' consumption is very high, but under the restoration of the "battlefield perpetual motion machine", he consumes and replenishes at the same time, and the consumption is definitely within an acceptable range.

Dong hero rushed over with his partner, and stared at the white cave in amazement outside the entrance of the cave. The hot air rushed towards him, not knowing whether to advance or retreat for a while.

Charles ignored them and continued to do his own business.

At this moment, a blood-sucking bat Bat King with a wingspan of ten meters rushed out from the depths of the cave, its body exuding the light of scarlet.

It realized that it had to escape today, so it sucked a lot of blood of the same kind around it, accumulated energy, and tried to break through the life-threatening wall of fire.

Charles didn't find it because the density of bats here is too high. The souls of ordinary bats are connected to cover up its existence.

Bat King, the blood sucking bat, underestimated the temperature of the wall of fire. The people on the other side of the wall only saw a ball of flame flying out of the wall, then falling to the ground, burning alone.

Charles continued to move forward slowly, the crystal clear and near-transparent 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, several meters wide.

Charles dissipated the wall of fire and got in.

There were also a dozen vampire bats that got in, and Charles used Fireball to kill them when they came in.

In the depths of the cave is an underground river, dark, I don’t know where it leads to.

He took out the lamp and looked around, and 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 into the rock look like no one has walked for a long time, and some stalactites have been erected on them.

He walked forward along the steps without the slightest hesitation.
