"Dear ladies! There are also dispensable lowly men! Rejoice!

Today! South, from the city of Ariedrin, has already brought us a wonderful kill.

But that's just the beginning!

Next, he will challenge the two-headed giant in a row! Dreadclaw! Trolls! Prince Kou Tao Fishman! Beholder! and a berserker powerful enough to make any dark elf tremble!

Whatever the end result, I'm sure you should be able to see what your heart desires most.

Yes!

Today's arena is destined to be bloody!

May the great Queen Rose bless every brave and fearless Dark Elf warrior!

Now, let the show begin! ”

With the innkeeper's impassioned roar, the iron door connected to the arena cage finally slowly opened.

A giant over four meters tall with two heads around his neck was driven out of it with a barbed whip.

He possesses very distinctly masculine features, shirtless without any armor or clothing, and his weapon is limited to a thick, long wooden stick.

But no one would doubt that this thing, once smashed, could turn a living person into a flesh-and-blood filling or patty in minutes.

You must know that although Faeron's two-headed giant is not very smart, and it is dirty and smelly, its combat effectiveness is absolutely unquestionable.

If someone could coin full-body plate armor on a two-headed giant, the behemoth could single-handedly destroy a heavily armed human army, even a formidable heavy cavalry.

Because even the horses and knights who launched the charge would still be fragile like a newborn baby in front of them.

On top of that, the two-headed giant does not have a lifespan and growth cycle of hundreds of years like other giants.

They grow up very fast, almost no different from humans, and their lifespan is about seventy-five years old.

Especially between the eight and ten months of the first year of life, they can quickly grow to more than two meters and have the ability to live independently.

Yes!

You read that right!

It only takes eight to ten months for a two-headed giant baby to turn into a fearsome hunter in the wild.

An adult two-headed giant's strength stat can usually reach an astonishing twenty-three points, and when they raise the thick stick in their hand, their best bet is to immediately turn around and run out of its attack range.

Otherwise, any action such as blocking or parrying is no different from looking for death.

Even with a sturdy shield, there is a high risk of being beaten to death with a stick.

However, just when everyone thought that this two-headed giant was the first monster that Zuo Si needed to challenge, a group of monsters with vulture heads and giant beetle-like bodies were also driven out of the dark passage.

You don't need to ask to know that this is the most characteristic monster in the dark region, and at the same time the most easily encountered monster in the wild-Dreadclaw.

As the name suggests, their most powerful weapon is the curly, sharp hook claws at the front of their upper limbs.

If you walk in a dark tunnel where you can't see your fingers and are ambushed by a dreadclaw, even a warrior as strong as a dark elf is likely to be disemboweled.

There is no doubt that six Dreadclaws plus a two-headed giant will be the first of the next four battles.

Facing so many monsters at once, even a veteran like the legendary ranger Trist couldn't help but sweat for Zuo Si.

However, Zuo Si himself didn't have much reaction to this, casually threw away the half-broken two-handed sword, bent down to pick up the magic giant sword left by Jody's death, turned around and hooked his finger at Venar outside the cage.

The latter hurried to the edge of the cage and asked in a slightly nervous tone, "Do you have anything to order?" ”

"What are the odds of the game now?"

Zuo Si glanced with interest at the tavern owner who was currying favor with the mother of Keyo not far away, and asked.

"Buy one to one if you can survive the first game, one to three to survive the second game, one to five to survive the third game, and twenty to one if you can survive four games to win the final victory." Without thinking, Venal said the odds of the game.

Hearing this answer, Zuo Si instantly showed an extremely cold and cruel smile: "Very good! Squeeze all the money we have and what we can pledge, buy me and win the final victory. Dare to use me as a tool to make money, and even want to manipulate my life and death? This comes at a cost. ”

Obviously, from the time when the tavern owner offered courtesy to the mother of Keyo, Zuo Si had already seen the other party's intentions.

This guy didn't even want him to come out of the arena alive, so he didn't hesitate to take out so many monsters at the bottom of the box at once, just to make a lot of money from it.

Of course, the tavern owner is not the only one who has similar thoughts, there are also a large number of gamblers who will lose if they buy Zuo Si.

After all, this is the city of Mosoblai, inhabited by 20,000 dark elves who are extremely chaotic and evil.

They didn't care about the life or death of a mere foreigner, even if this outsider killed the martial arts chief of the third-ranked family, and also attracted the attention of a mistress and several high-ranking priestesses.

They just want to see images of cruelty, gore, and death, and make a lot of money from gambling by the way.

"As you wish!"

Venar undoubtedly felt the unhappiness revealed in Zuo Si's eyes and tone, and without saying a word, he walked towards the bar where he was busy counting gambling money and accepting bets from customers.

It didn't take long for her to convince the other party to convert the entire caravan of goods and slaves into 100,000 gold coins, and then add some messy magic items, scrolls, and cash, and finally completed the largest bet ever made in the entire tavern for 170,000 gold coins.

And this move suddenly made the tavern owner, who was still smug in the last second and seized the opportunity to get rich overnight, become sweaty in the next second.

Because he's not a fool and knows what it means for Venar to bet so high.

This means that Zuo Si has absolute confidence in his own strength!

Confident that even in the face of terrifying monsters like the Eye Demon, the Kou Tao Fish-Man Prince, and the Berserker Demon, he is sure of winning the final victory.

Again, this was terrible news for him.

Because in his arrangement and calculation, Zuo Si can only play the second round at best, and then he will die in the third round.

That's why winning the fourth game will offer exaggerated odds like 20 to 1.

If you don't open it higher, how can you attract the wronged boss to take the initiative to take out all the money in his pocket?

But the problem now is that if Zuo Si really came out of the arena alive, then with the current betting situation, even if the tavern owner went bankrupt and sold himself into slavery, it would be impossible for him to pay the millions of gold coins in his hand to the person who bet.

According to the laws of Mosoblai, those who can't afford to pay their debts will most likely end up worse than being enslaved.

"Boss, do you want to ......?"

Another dark elf male next to him made a throat-slitting motion with a very subtle motion.

As the embodiment of chaos and evil, the Dark Elves live by the truth that nothing has happened as long as there is no evidence.

So expecting them to be honest and follow the rules is completely daydreaming.

In the case of the arena of this tavern, it is not uncommon to manipulate the outcome of a battle through a few small means.

In fact, it's not uncommon to add ingredients to a glass of wine or a bottle of healing potion used to heal injuries at the start of a match, such as some hallucinogenic mushroom powder, or an alchemical poison that dulls the senses and reactions.

In short, when it comes to poisoning and plotting against others, the Dark Elves have a terrifying talent that outsiders can't imagine.

Many of them have successfully poisoned their siblings when they were children.

Of course, if the target is very cautious and refuses to drink anything from a stranger, there are also a large number of traps hidden under the arena floor, which can spew poisonous smoke or fire enough to burn a person alive at any time.

The Tavernkeeper only needs to find a random reason such as to make the battle more interesting, and can activate these traps to cause trouble for the people inside, or even kill them outright.

Anyway, what most guests want to see is just blood and carnage full of sensory stimulation.

As for who killed whom, they didn't care.

"Don't act rashly just yet! At least wait until the first battle is over. The matriarch and eldest daughter of the Obroza family were watching the battle, and I feared it would be self-defeating to play with those little tricks in front of several high-ranking priestesses. ”

The tavern owner hesitated for a long time, but finally gave up on his tempting offer.

Because he didn't dare to bet that the Lady of Kyo, who wielded great power, would suddenly turn her face when she noticed it.

But what the tavernkeeper didn't know was that the conversation he had just had with his men was clearly heard by another dark elf girl hiding in an inconspicuous corner.

Not only does the girl have a stunningly beautiful look, but she also wears a badge on her chest that symbolizes a member of the "Banrui" family.

On top of that, she doesn't wear the serpent's whip, a weapon that symbolizes her status as a priestess of Rose, like most Dark Elf aristocratic women.

Instead, he carried with him a spellbook used to transcribe arcane magic, as well as several valuable magical items.

"Conspiracy, betrayal, poisoning, assassination, Mosob's life in the city is really set in stone." The Dark Elf Maiden sarcastically said in a slightly disdainful tone.

Just as she was about to get up to leave, she suddenly noticed a piercing scream and cheer erupting around the arena not far away.

I saw Zuo Si, who was standing in the middle of the iron cage, actually under the siege of a two-headed giant and six dreadclaw monsters, with a calmness and elegance that cannot be described in words, completed a ring of magic [greasy technique] between the electric light and flint.

As a result, the group of monsters slipped and fell to the ground at the moment when they were about to rush closer.

In particular, the two-headed giant, which weighed more than two tons, directly crushed one of the dreadclaws into a meatloaf when he fell.

The hard shell of the latter's body did not play any protective role at all, but squeezed out the flesh and internal organs under the huge external pressure, making a muffled thud.

One of the kidneys flew out of the middle of the shell, landed on the ground less than a meter away from the girl, and then bounced high.

As a very rare arcane magic user among dark elf women, the girl was completely shocked by the right timing of the magic in front of her, and not only subconsciously stopped, but also stared at the man in the cage who looked younger than herself.

Next Second......

Zuo Si used an even more gruesome way to complete the lore of five dreadclaw monsters and a two-headed giant.

He lifted his finger and aimed it at the Two-Headed Giant's eye and shot a large expanse of hot, deadly white steam.

One Ring of Magic [Steam Jet]!

This is a magic spell with a very similar power and range to the [Burning Hand], which can affect all creatures within a fan radius of about ten meters in front of it.

When the terrifying heat of steam sprayed into the eyes of the two-headed giant, the behemoth immediately fell into a frenzy due to unbearable pain, picking up the deadly club in his hand and smashing wildly.

Before the two dreadclaws could react to what was happening, they were blown out in the head by a thick wooden stick that fell from the sky.

When the other three dreadclaws found out that their companion had been killed, they didn't bother to pay attention to Zuo Si, who was hiding far away, and turned around and attacked the two-headed giant.

Due to the effects of greasy spells on the ground, they were unable to get up from the ground for a short time, and could only wrestle together on their stomachs in an extremely ugly and savage manner.

Among them, the dreadclaw monster waved its sharp hook claws and constantly left terrifying and hideous wounds on the giant's body, and the giant couldn't see anything because his eyes were burned by steam, and when he felt that something was attacked, he immediately swung the club in his hand and smashed it.

In this way, the injuries on both sides are getting worse and heavier, and the blood is flowing more and more.

Finally, when they were all exhausted and could no longer move, Zuo Si walked over with the giant sword in his hand, ending his tragic life one by one.

With just two rings of magic, the two-headed giants and dreadclaws that required an entire Dark Elf patrol were easily dealt with.

Not to mention the ordinary dark elf audience stunned, even the Lady of Keyo, who had always maintained a high posture, couldn't help but get up from her seat, with an expression of disbelief on her face.

There is no doubt that this kind of fighting style, which is full of skill and wisdom, is completely opposite to the performance of killing Jody with pure swordsmanship and brute force just now.

What's more, Zuo Si also showed arcane spellcasting abilities for the first time.

Poof!

Poof!

Poof!

The Dark Elf Maiden only felt that her heart was beating wildly, and her brain was completely filled with an inexplicable excitement and excitement that could not be described in words.

Because she found that the spell-casting skills displayed by the young man in the iron cage in the battle just now were the "improvisation" that her father, as an archmage, often emphasized.

Regardless of the level and power of a spell, it is only based on whether it is suitable for the current environment and situation, and through observation, understanding and analysis, you can decide which spell is most effective.

Thinking of this, the dark elf girl immediately rushed to the side of the arena iron cage like crazy, and shouted at Zuo Si, who was wiping the bloodstained sword body, "Hey! Stranger! How did you do that? ”

"Huh? What and how? ”

Zuo Si was slightly stunned for a moment, raised his head and stared at this dark elf girl who was still very beautiful and beautiful even by the standards of human beings in modern society.

"Magic! Just when you used magic! The girl hurriedly added.

"Ahh That's just the result of a long period of combat experience. After all, the two-headed giant and the dreadclaw monster are not intelligent creatures, and their weight is very amazing, and such a monster will inevitably have a very strong impact when it falls, so the greasy spell will play a good role. As for the [Steam Spray], it is simply to make the two-headed giant go berserk, thus inducing these two groups of monsters to kill each other. Zuo Si explained with a smile.

Because he suddenly found that the girl in front of him was different from the other chaotic, evil, and bloodthirsty dark elves around her, not only had a pair of very bright and clear eyes, but also full of curiosity, and a strong desire for magic.

"I see!"

The Dark Elf Maiden nodded thoughtfully.

"If you don't mind, can you tell me your name?" Zuo Si quietly probed.

The Dark Elf girl pursed her lips and replied with a smile, "My name is Rizzle, Rizzle Banry, and it's a pleasure to meet you. By the way, the tavernkeeper over there doesn't mean anything to you. ”

"Lireel Banry? You're the daughter of Archmage Gongfu? Zuo Si raised his eyebrows in surprise.

He obviously didn't expect that on his first day in Mothorb, he would meet this dark elf woman with almost the same rebellious personality and legend as Trist.

It's just that compared to Trist's upbringing, which was full of darkness, pain, betrayal, and death, Lireel's childhood was obviously much happier.

Because this girl's father is one of the few people in the entire city of Mosobulai who is really qualified to control his own destiny, a legendary mage with a spell casting level of more than lv20.

Even the current matriarch of the first family, Ban Rui, did not dare to call this brother a lowly man when facing him, but wanted to talk to him with an equal attitude and identity.

Therefore, Gongfu Banrui's position in the city is very special, so special that as a man, he even has the right to choose his own spouse, and use the other party as a tool and a doll to vent his desires.

When the archmage learned that one of his mistresses was pregnant and had given birth to a daughter with magical talents, he immediately killed the former without hesitation.

After all, the dark elves are matriarchal, so the first ownership of the child will always belong to the mother.

Only by killing his mother can he take over the custody of his daughter reasonably and legally.

Immediately after, Lireel, pampered by her own father, Gongfu, lives a free life that other Dark Elf children can barely even imagine.

She didn't have to worry about being whipped by a high priestess for making a mistake, she had a mansion of her own, a large number of servants and slaves revolving around her, and even a small zoo to keep the animals she was interested in.

While young Trister was suffering from the ravages and devastation of her sisters, Rizzel could leave home at any time and go to the tavern to drink with the rude mercenaries, throw darts, learn the lingua franca from human slaves from the surface world, and even make friends with each other, sneaking out of Mothor to venture into the dark realms.

It can be said that the childhood of any dark elf compared to that of Lirel would be extremely dark, painful and hopeless.

And it is this unfettered and free life that makes the dark elf girl not as evil as her own compatriots, but a bit as willful as the spoiled rich lady.

Without outside interference, she will soon be on her way to the surface world and become a follower of the Dark Maiden Yin Listur.

But now, Lireel should still be forced by the current head mother of the Ban Ray family, Trill to enter the Spider Church to study religion, and prepare for the future to become a traditional high priestess.

"You know me?"

A look of confusion appeared on the dark elf girl's face.

After all, her fame was only limited to Mosobulai City, and outsiders like Zuo Si shouldn't know about it.

Zuo Si smiled and replied, "Of course! Being a woman and carrying a spell book instead of a snakehead whip in a dark elf city is a bit unconventional, you say? ”

"Hahahaha! You're funny! At least much better than the guys who look in awe when they hear my father's name and family name. If you make it out of it alive, I'll invite you to my house for a drink, how about that? Liriel winked playfully.

"It's my pleasure." Zuo Si agreed without hesitation.

While the two were talking in a whisper, the closed iron door at the back of the arena finally opened again, and a large group of goblin slaves rushed out of it, hooked the corpses on the ground with iron hooks, and dragged them into the nearby sewer that led to an unknown place.

However, considering that food is relatively expensive in the dark region, the dark elves have a habit of never wasting food.

Eighty percent of these corpses are processed and then fed to slaves or carnivorous monsters to eat.

After the body was cleaned up, the tavern owner, who had an ugly face, walked up to the front desk again, barely squeezing out a smile and shouting at everyone: "Look! Soth from Aridlin City!

The most courageous warrior of the Great Rose God Queen!

Kill a two-headed giant and six dreadclaws without much effort!

What a glorious achievement!

Next, to make the combat even more challenging, I decided to bring the most terrifying Eyefiers of the Shadowlands into play.

Rejoice! The people of Mothoblai! You're about to enjoy a great fight. ”

Hearing the word Eye Demon, many of the dark elves present couldn't help but gasp.

Although their dark skin gives them great magical resistance, they can't hold up for a few rounds in the face of the endless rays of the Eye Demon, and they will be charmed, petrified, dissociated, or even die directly from the powerful negative energy rays.

Soon, at the signal of the tavernkeeper, a huge ball of brown meat slowly flew out from behind the iron door.

Along with it, there are four underground trolls controlled by the Enchanting Ray.

"Wow! This is the Adult Eye Demon? It looks a little scary! ”

Lireel subconsciously took two steps back.

Because she knew very well that the anti-magic force field emitted by the eye of the demon lord was definitely an out-and-out nightmare for the spellcaster.

With his current pitiful spell casting level, he doesn't have the ability to fight against it at all.

But Zuo Si smiled disapprovingly, shrugged his shoulders and comforted: "Don't be afraid! It's just a mere demon. In fact, this creature is not as difficult to deal with as you might think, especially the Eye Demon who has lived in a dark underground environment for a long time, and actually has a very fatal flaw. ”

"Oh? What is the flaw? Lireel asked with interest.

"Yes...... Light! ”

At the moment when the last word blurted out, Zuo Si raised his hand and released a strong flash of light that was enough to blind everyone around him.

One Ring of Magic [Dawn Burst]!

This is a typical Shaping spell, which has the effect of creating a light source that is thousands of times brighter than sunlight within a radius of a few meters around.

Although it does not cause any substantial damage on its own, it can cause blind eyes for a short period of time for underground creatures accustomed to the darkness, accompanied by a strong stinging and burning sensation.

Strictly speaking, [Dawn Burst] should be regarded as a super enhanced version of Zero Ring's [Flash Technique].

When this spell took effect, the entire hall suddenly erupted in a burst of painful wails and screams, and many people covered their eyes while crying and cursing hysterically.

Obviously, Zuo Si's indiscriminate attack had made all the dark elves suffer.

Of course!

As a direct victim, the Eye Demon completely lost his perception of his surroundings in the first few seconds of his appearance.

Whether it was the huge main eye or the eye stalk that grew around the meat ball, they all closed after the bright light flashed.

As we all know, when all the eyes of an eye demon are forced to close, it is when it is at its most vulnerable.

Zuo Si unceremoniously raised his hands and began to chant incantations loudly, completing a series of spells before the audience could regain their vision.

He first forcibly reduced the magic resistance of the Beholder.

A fireball and ice storm ensued, killing the terrifying monster in the Shadows along with the trolls it controlled.

The whole process took less than a minute!

When the dark elves in the tavern regained their sight, all that was left in the arena was half-charred, followed by corpses frozen in ice.

"Damn! What just happened? A dark elf warrior asked his companion in an uncertain tone.

"It's magic! The Outlander used his magic to kill the Eye Demon and the trolls it controlled! ”

Another male warrior next to him replied in a tone of uncertainty.

"Yes...... But isn't he a warrior? ”

"Warriors? No kidding! Which warrior have you ever seen who can use arcane magic above the four rings? This guy is a mage at all! ”

"Nope! Wrong! I think this guy should be a warrior and mage! ”

"No wonder he didn't wear armor! It turned out to be for the convenience of casting spells at any time! ”

Obviously, the dark elves were not as ignorant and ignorant as the ordinary inhabitants of the surface world, and quickly judged some of Zuosi's strength from the battle just now.

While the Warrior-Mage class combination isn't very common, it's not entirely absent.

It's just that there are too few people who can give full play to the advantages of these two professions.

Most of the "tactics" basically either forget to use spells in battle and patronize the sword-swinging and slash people, or they dare not confront the enemy, and only know how to hide behind their teammates to release spells, and they can't give full play to the advantages of part-time fighters.

Seeing that the Eye Demon he had carefully prepared was easily killed, the tavern owner finally panicked, and immediately grabbed his subordinates by the collar and asked sharply, "The only monsters we have at hand are a Kou Tao Fish-Man Prince and a Berserker, right?" ”

The latter hurriedly nodded vigorously: "No...... That's right! Boss! There are exactly two battles left, and we can only send one at a time. As for the remaining slave cannon fodder among the orcs, half-orcs, and bear goblins, they shouldn't be able to threaten the outlander at all. ”

"Damn! Give me both monsters in the next game! Remember! Do whatever it takes! Absolute! Absolute! That guy will never be allowed to come out of the arena alive! Otherwise, I'll screw your head off!" The tavernkeeper threatened viciously.

"At all costs?"

The Dark Elf's men raised their heads, their eyes glinting with a vicious light.

"That's right! Just do it! I'll take care of all the consequences! ”

With that, the tavernkeeper raised his glass and drank the liquor inside, his face full of madness, like a gambler who has pressed all his chips.

On the other side, the lady of Kayo was sitting in the VIP seat specially prepared for herself, constantly sticking out her tongue and licking her black and purple lips, and commented in a slightly excited voice: "What a good young man, isn't he? I now kind of understand why he dared to speak to me in that tone. ”

"Mistress, would you like to invite him to join our family and take Jody's place?" The eldest daughter asked cautiously.

The lady smiled and asked, "Why not?" It's just that I haven't decided whether to give him the title of acolyte, or the title of martial arts chief. ”

"Father-in-waiting? I'm sorry, Mistress, but I doubt that he is capable of fulfilling this duty at his current age. The eldest daughter glanced at Zuo Si not far away with a slightly playful gaze.

"Hehe, it's okay, I have enough patience to wait for him to grow up and tune him into my favorite shape. And...... Don't you think it's a fun and tasteful game? Mother Queyo said meaningfully.

"Your interest and appetite are as good as ever. Understood, I'll be in touch with him personally when the fight is over. The eldest daughter gracefully owes herself.

Mistress Keyo got up and moved her numb legs a little, stretched out her hand and dragged the eldest daughter's chin, and said in a slightly playful tone: "Don't worry, dear daughter, I will not monopolize this fine young man for too long. Once you've tasted it, I'll allow you to share it with your sisters, just as you did with Jody. Because I found that maintaining this relationship can ease the conflicts within the family and make us more united. ”

"I am touched by your kindness and kindness."

The eldest daughter bent down and kissed the back of her mother's hand deeply.

Just as the mistress was about to say something, a male warrior wearing a noble badge walked over from a distance, lowered his head and reported in an emotionless tone, "Mistress, I noticed that the owner of this tavern is trying to manipulate the outcome of the match.

One of his subordinates had just injected Prince Kotao with a terrifying alchemical potion that could maximize his potential.

However, the price is a maximum of ten minutes, and this Kou Tao Fishman Prince will die in an instant.

Not only that, but he also asked his subordinates to send the drugged Kou Tao Fishman Prince and the Berserker Demon to the field in one go in the next battle.

Apparently he wanted to kill the stranger named Thus.

In addition to this, several others tried to poison the outlander's drink and potion. ”

"Oh? He shouldn't have been hit, right? A smile appeared on the mistress's face.

The male warrior immediately shook his head: "No! Quite the opposite! He drank all the potions and drinks that had been sent to him in question. But what struck me as strange was that after drinking, he not only gave exactly what each additional poison was in, but also had a very precise estimate of the dosage and possible effects. ”

"What do you mean...... Did he drink it on purpose? The eldest daughter's eyes widened in disbelief.

"Yes. What's even more interesting is that he himself did not have any adverse reactions, but all the guys who gave him potions and drinks were poisoned by their own hands in the next few minutes, and his death can be said to be quite miserable. ”

As he said this, the male warrior raised his head and smiled sinisterly.

You don't need to ask to know that he admires Zuo Si's unique way of revenge, and can even be said to worship it.

"Hahahaha! It's getting more and more interesting. Now that Soth already knows who wants to be against him, let's do what this good young man will do. ”

The mistress laughed and sat back in her place, looking at the arena below with expectant eyes.

At the same time, when the old side of the tavern learned that all the men sent to poison had died, and that they had all died of the poison they had inflicted, a bead of sweat broke out on his head.

If it weren't for the fact that his dark skin would have caused his complexion to never change at all, it is estimated that his entire face would be pale by now.

Obviously, anyone who is not a fool knows that this is a means of revenge for the other party to see through their little tricks.

What he really feared was that the guys in front of him who had died of poisoning had no scars from head to toe, and there was no sign of poison in their mouths and noses, it was as if someone had injected toxin into their bodies out of thin air, and it was hundreds of times more than before.

"Old ...... Boss! What are we going to do now? A dark elf male's eyes revealed intense fear.

"Now? Now we can only count on the drugged Kou Tao Fish-Man Prince and the Berserker Demon to fight for energy. ”

The tavernkeeper sat on the ground like a deflated ball in an instant, gasping for air.
