A little red light flew closer, and under the illumination of the night pearl, Li Muran finally saw the true face of these red lights.

It turned out that there was a group of pitch-black bats, each of which was several feet in size, more than ten times larger than ordinary bats, and that little bit of red light was the bloody eyes of these bats.

"Bloodthirsty bats, first-class demon beasts, only active at night, often live in dark places, and are good at eating the blood of humans and animals. Li Muran's mind immediately appeared with the relevant records in the classics.

Although the bloodthirsty bat is only a first-level demon beast and its strength is low, if it only encounters a lone bloodthirsty bat, Li Muran doesn't care about it at all, but there are at least twenty or thirty bloodthirsty bats here, if they are besieged by it, it will be very bad.

Li Muran's sacrifice of dozens of zhang talismans turned into a ball of fireballs the size of a foot, bursting in mid-air, and in the huge roar, the flames splashed everywhere, completely illuminating this ravine.

Some of the bloodthirsty bats that couldn't dodge were suddenly swept up in the flames of the explosion, and they disappeared in an instant, but most of the bloodthirsty bats were able to shake their wings to avoid it, and each opened their mouths to spit out a burst of invisible sound waves, blocking out the splashing flames.

Not only that, these bloodthirsty bats also spewed out sound waves towards Li Muran, and after this invisible spell hit the vajra cover on Li Muran's body, the vajra cover shook slightly, although it couldn't break the vajra cover, but it made the vajra talisman lose a lot of vitality.

This is the "sonic technique", which is said to be the only spell that the bloodthirsty bats can do, and to Li Muran, a sonic wave is insignificant and cannot be a threat, but if these twenty or so bloodthirsty bats continue to spew sound waves like this, he can't bear it!

"It must be decided!" Li Muran's mind moved, and his hands simultaneously cast the Flame Explosion Technique, and in a few moments, four or five fireballs shot out in a flash, hitting one of the bloodthirsty bats.

If other disciples saw this scene, they would be surprised, among the disciples who had only cultivated for more than a year, it was already rare for them to be able to skillfully perform the Flame Explosion Technique and successfully cast the Flame Explosion Technique with a snap of their fingers; those who could perform two or three Flame Explosion Techniques in a row were also considered geniuses, and they were proud of it; and a person like Li Muran who could open his bow left and right and perform the Flame Explosion Technique with both hands at the same time, and it was a continuous cast, which could be said to be unique!

However, Li Muran can only do such smooth spell casting in the night environment, and he can't do it in the daytime environment.

The bloodthirsty bat hurriedly spat out sound waves in front of him, but several flame blast spells struck continuously, immediately crushing its invisible sound waves, and the bloodthirsty bat also turned into smoke in the flames.

Li Muran concocted the spell again quickly, and under the sacrifice of several flame explosion techniques, another bloodthirsty bat was killed in an instant.

However, at the same time as he killed the two bloodthirsty bats, the other bloodthirsty bats swallowed another sonic wave technique and attacked in front of Li Muran.

The vajra cover on Li Muran's body vibrated violently under the invisible sound wave attack, and the golden light gradually dimmed, and it was precarious.

"It's still too slow to kill demons like this!" Li Muran's heart moved, and with a stretch of his arm, he pointed at the most dense place of the bloodthirsty bats, and stirred up the Dark Moon Crossbow hidden in his sleeve.

Suddenly, the three spirit stones inlaid on the Dark Moon Crossbow turned into flying ashes at the same time, and the three quintessential Heaven and Earth Yuan Qi were absorbed by the Dark Moon Crossbow and converged on the three short arrows. Immediately, three short arrows shot out in a volley, fast and urgent, mixed with a sharp whistling sound.

Although the bloodthirsty bat flies very fast, it is obviously much worse than this short arrow, and the bloodthirsty bat cannot dodge, so it can only spit out sound waves to protect itself.

"Puff puff!" A few soft sounds, three short arrows lightly pierced through the invisible sound waves, piercing the body of the bloodthirsty bat.

Each short arrow killed at least one bloodthirsty bat, and one of the short arrows also pierced two bloodthirsty bats at once.

"This Dark Moon Crossbow is really invincible! It's just a pity that it can't be used continuously!" Li Muran secretly said in his heart, the Dark Moon Crossbow only has three arrows, and if he doesn't take back the short arrows after shooting, he can't continue the next round of attacks.

Li Muran touched it in his arms, and nine black flying knives as thin as cicada wings were taken out by him, and then his hands flung around, and in the sound of brushing, several bloodthirsty bats were also hit by the flying knives, and they were instantly killed or injured.

These flying knives are incomparably sharp, and the bloodthirsty bats are only first-level demon beasts, and they can't resist them head-on.

However, Li Muran was not a fugue monk, and after the Flying Knife Artifact was sacrificed, he could not be made to take it back on his own initiative.

Although Li Muran killed half of the bloodthirsty bats in a moment, there were still more than a dozen bloodthirsty bats that refused to leave and continued to besiege Li Muran.

"You have to use a higher-level talisman!"

Li Muran took out a stack of more than ten palm-sized talismans from his arms, and showed a trace of pity on his face, but this look was only fleeting, and then, he did not hesitate to sacrifice all the talismans, and each talisman hit a bloodthirsty bat.

After the seals of these talismans were stirred up by Li Muran, they immediately turned into a thin and long blue light, and the blue light rushed towards the bloodthirsty bat, turning into countless vines in an instant, tightly winding the bloodthirsty bat.

This is a wood-attribute spell talisman winding talisman, this kind of winding technique is a spell that Li Muran learned to use after advancing to the middle stage of the qi vein, and it can only be cast at night when the mana is particularly smooth;

The binding douwen that needs to be drawn to make the winding talisman is very difficult, and it is one of the most difficult types of douwen in the beginner level of the five elements, even if it is a disciple in the late stage of the qi vein, it is difficult to master the drawing of this douwen, so the success rate of the talisman is not high, and the price of the winding talisman will naturally rise. And Li Muran has the help of a mysterious bronze mirror, and he rarely misses, almost as long as he can cast a spell along with him, he can make the corresponding spell rune.

Under the restraint of the winding talisman, each bloodthirsty bat was tightly wrapped in the green vine, and the flesh wings could not be opened, and they all fell to the ground one by one.

Some bloodthirsty bats desperately spewed out invisible sound waves, trying to shake the shackles of this green vine, but the green vine has a strong toughness, and the invisible sound waves alone have almost no effect on it.

This is also a thing, if it is the iron-winged eagle facing this winding talisman, it is not afraid at all, it only needs to fan out the extremely sharp wind blade, it can cut off all the green vine fast knives that the entanglement talisman conjures conjure, and although there are a lot of these bloodthirsty bats, they have no means to instantly cut through the green vine, and they are very restrained by this winding talisman.

Li Muran took the opportunity to lift a golden knife magic weapon, bullied into the side of those bloodthirsty bats who couldn't move, and killed most of the bloodthirsty bats on the spot with a knife, only two or three bloodthirsty bats took advantage of the fact that Qingteng did not completely entangle themselves, struggled a few times and escaped, flew out of the ravine far away, and escaped into the darkness.

"It's finally solved!" Li Muran's heart was relieved, he retrieved the short arrows and flying knives he shot one by one, and then used the golden knife to break open the corpses of the bloodthirsty bats and find out the essence in their bodies.

A total of eleven complete bloodthirsty bat essence elements were found, these were the essence elements of first-level demon beasts, which were of little use to the cultivation of disciples in the middle stage of the qi vein, but they also had a certain value, and they could be sold for a good price in the market. Moreover, there is no need to hand over such things as demon beast materials to the sect.

Li Muran thought: "The first-level demon beast essence element is very limited in the increase of mana, but these bloodthirsty bats are all nocturnal and diurnal, and they have survived in this underground tomb city for so long, there should be something special." The special thing about my divine light is that it can only shine in the night environment, I wonder if these bloodthirsty bat essences will be useful to me?"

Li Muran temporarily put these essences into the jade box and left them to try their effects later.

"Demon beasts choose their nests, and they generally choose the place that is most conducive to their cultivation. Either the Heaven and Earth Vitality is abundant, or there are other strange treasures! For example, the Iron-winged Eagle has set its nest next to the thousand-year-old elixir Mo Lingzhi. When Li Muran thought of this, he held back the smell and searched carefully in this ravine.

Not long after, he found a vein of Darkgold Stone - this is also a common treasure in the Catacombs, Darkgold is very widely used in refining, but the production is not small, so the price is not very high. Li Muran used the golden knife magic weapon to dig out more than a dozen fist-sized high-quality dark gold stones, and he ignored the other scattered small pieces or poor quality dark gold stone mines. Anyway, these treasures are originally of ordinary value, and they all have to be handed over to the sect, and they spend a lot of effort digging more, and the rewards they get are actually not much.

Li Muran checked in the ravine and found nothing else, then left here and continued to explore other places.

An hour later, Li Muran, who was carefully picking a hundred-year-old dark night grass, suddenly his expression changed slightly, he put the dark night grass aside, and then took out a jade talisman from his arms.

This is the transmission note that Master Zixia Dao handed over to him and his disciples, and at this time, the transmission note is constantly flickering and vibrating slightly, which is exactly the reaction when the news is transmitted.

Li Muran entered a spell and unlocked the seal on this transmission note, and immediately a familiar middle-aged man's voice came, it was Zixia Dao.

"Master urgently summoned us and others, I don't know what the so-called matter?" Li Muran's heart sank, but he still followed the master's order and rushed to the place designated by the master as soon as possible.

Li Muran didn't use the Fu Paper Crane, and when he arrived at the designated place, he saw that most of the disciples such as Qingfengzi and Mu Li had already arrived here one step ahead of him.

"The other senior brothers may have the paper crane in hand, so they came quickly. Senior Brother Mu also came so quickly, could it be that he happened to be nearby?" Li Muran thought a little strangely, but he didn't pay too much attention to it.

"Senior Brother Zhao, you came just in time!" Mu Li greeted Li Muran from afar, and shouted excitedly: "Today, we will open our eyes, and the master will personally cast a spell to destroy the demon!"
