"Lao Fan, add blood!" The thief also looked at the clone that had just been summoned by him, and after disappearing into the palm of the blackened bone dragon boss, he immediately roared, and he was holding an empty potion bottle in his hand.

"Wait!" After Zuna finished speaking, he directly used up the quota of the last doppelganger in the shadow of the undead.

As Mina's doppelganger appeared and moved away from Mina, Mina immediately focused his spirit on the blackened bone dragon boss again.

The current Mina, after wearing the Flame Crown, has been accumulating fire energy, although this also makes him unable to use water, ice, or even wood-based magic, but the powerful lethality of the fire system is not comparable to other systems.

In this battle, which has lasted for 4 hours, Mina's output accounts for almost 99%, but this boss's HP has only dropped by half.

And the thief on the other side also has a way, and now he is very embarrassed, and his combat power is basically negligible for this tall blacken.

But his role is very important, as long as he is still alive in front of the blackened bone dragon, then this bone dragon will not attack Mina.

This is a hidden effect of Mina's Dark Seal, when he faces undead creatures with players or NPCs from the Holy Light faction, as long as the creatures of the Holy Light faction do not die light, then Mina will never be attacked by the undead.

But, of course, he can't rush to the front, otherwise he will be hit by a stray bullet or something, and he will have to lose blood or even die.

The medicine on the thief Youdao has almost been eaten, and this blackened bone dragon is still immune to stun and all toxin damage, so the ability of the thief is completely abolished.

Now he is taking the boss around this altar, but this bone dragon boss is not easy to deal with.

Once far away, it will strafe a large area with that dark breath. Running closer, there is a way to almost kill the thief in seconds. This makes the thief very depressed, and he can only continue to use the clone to attract firepower, and at the same time to contain this boss.

After turning around and shooting a crossbow arrow, the thief immediately jumped away.

And the moment the thief jumped away, a fist that only had bones, but was terrifyingly large, smashed into the position he had just now, and a small pit appeared.

The speed of this blackened bone dragon is very erratic, sometimes fast and sometimes slow, which makes the thief also very distressed, and constantly accommodating it.

To be honest, neither long-range dragon breath nor melee slapping is something he can afford, although his health is very thick, but his defense is not as ironclad as that of a warrior. Moreover, there is a way for thieves who have been using clones, and their health has never been full.

On the other side, Mina's doppelganger, under the control of Mina, constantly plays defensive auxiliary magic such as hydrotherapy or acceleration to the thief, and at the same time, he also has to play an ice-based elemental bird to help the blackened bone dragon slow down and the like.

"It's painful!" The thief also has a way to know how many times he has let out such a wail.

Fight a boss for 4 hours, and only 50% of the health is down, which is beyond the capacity of most players.

"It's better to be in pain than to regret it later, work hard, boy!" Mina teased.

"But...... I regret it now! "Although the thief also has a way to say so, but the action is still as agile as before, every time in the moment of the boss attack, as if he can predict the prophet, he doesn't even need to look at it to know the timing of the dodge.

This kind of ability, Shui Nai also has it, but it seems that it is the first time he has seen that the thief also has such a strong sense of crisis.

"Try hard, it's a big deal, the last knife is good for you." Mina knew that he couldn't give up this boss, and he knew that he wanted this last knife to say so, so he brought it up directly.

"Lao Fan, I love you!"

"Damn!" Mina was shocked, and the Flame Bird on the Elemental Wand almost hit the thief Youdao.

And just when Shui Nai and the thief used words to dissipate the pressure on their bodies, the shadow wolf on the other side suddenly jumped on the back of the bone dragon and bit it hard.

This shadow wolf has long since lost any dissent, and after seeing Minai and Thief Youdao fighting with such a bone dragon that makes it tremble unconsciously, its original little dissatisfaction has almost dissipated.

In nature, wolves, such arrogant and social creatures, tend to be loyal to the head wolf, although the thief is not a wolf, but his strength has convinced this shadow wolf, so naturally there will be no more rebellion.

Therefore, the current shadow wolf is very hard to attack this black bone dragon boss.

Its attack power is much more powerful than that of the thief, and it likes to sneak attack, so it fights well, but the defense is too weak, and you have to rest for half a day after a fight.

"There is a way, with the body, I am going to make a big move!" At this time, Mina suddenly felt a heat all over his body, and after glancing at the skill bar, he immediately shouted with the thief.

"Good!" After the thief finished speaking, he saw the red dots around Mina flying, and after that, all the red dots poured into Mina's elemental wand in an instant, and a purple flame appeared on Mina's wand.

This is Mina's Purple Flame Heavenly Fire, which is basically one of the strongest single fire-based magic spells in addition to the forbidden spell.

And when the thief also used the vanishing skill to throw all the hatred of this boss to the clones around him, Shuinai's purple flame skyfire also fell from the sky.

The purple flames shrouded almost the moment the blackened bone dragon boss slaughtered all those clones, and this high-heat flame with extremely terrifying frightening directly burned the bones of the blackened bone dragon boss to a "click".

The huge blood bar of this blackened bone dragon boss also exploded with a damage of nearly 400,000 directly at the moment when the flames were added, and then slowly descended at a steady speed under the afterburns.

Although the duration of the Purple Flame Heavenly Fire is a bit short, it still directly kills this blackened bone dragon boss with a full 8% health.

"There is a way, go on!" After Mina finished speaking, she hit the elemental bird of one again, repeating the work just now.

In this necromantic mountain filled with the breath of the necromancy, the undead's blood regeneration speed is so fast that it is overwhelming, and it can directly recover % of the speed per second, which basically makes Mina's elemental Asuka fight without much temper.

If Mina didn't have such a skill that could burn blood a lot, he wouldn't be in the mood to fight again.

In fact, this blackened bone dragon boss relied on this trick to get into what it is now. As for the other attacks, they were only able to suppress its health regeneration speed.

"Okay!" The thief, who had just rested for less than half a minute, had to run in front of the blackened bone dragon boss again.

So, the battle between the two, a dragon and a wolf, began again.

After holding on for another 4 hours, Mina and they finally grinded the HP of this boss to the level of 5%, and now as long as Mina has another Purple Flame Skyfire, then it will be basically relieved.

However, at this time, the blackened bone dragon once again entered a state of rage, not to mention the rapid increase in speed, and its body also began to emit black light.

"And the ultimate?" Seeing that the thief here also had a way, he immediately thought of this, so he didn't think much about it, and directly launched the wind element incarnation of the Wind Thief, intending to survive this trick first.

I saw that the black bone dragon's bone hand with black light tore the body of the thief and the dao fiercely, and at the same time, the shadow wolf that skipped over and intended to protect the lord was also torn in half, and a critical blow damage of more than 50,000 slowly appeared.

Mina shuddered as she looked at the black energy claws that were almost 2 meters long.

Even an elite-level pet like a shadow wolf, which is not weak, has to be killed in one move, and if this move hits the player, who can survive it.

"Lao Fan, how long is it left!"

"Half a minute." It would take more than half a minute for Mina's Purple Flame Heavenly Fire to complete the accumulation of Flame Energy. "There is a way, you retreat first, I will block it with the undead projection!"

Shui Nai knew that the thief could no longer stand it, under the incarnation of the wind element, although he could not be physically harmed, but the attack of this blackened bone dragon obviously carried the energy damage of the dark attribute, plus repairing the body would also consume the upper limit of the stamina value, once the upper limit was used up, the thief would have to be almost the same.

"Good!" The thief also knew that he wouldn't be able to hold out for half a minute, so he began to quickly sweep out.

Although the speed of the blackened bone dragon has increased a lot, the thief in the state of the wind element incarnation has also increased even more, and it has disappeared all of a sudden.

At this time, a vampire projected from the shadow of the Minai Undead quickly rushed to the bone dragon and launched an attack on it.

Although it was shattered to pieces by the black energy emitted from the bone dragon at the moment of attack, it successfully attracted the attention of the black bone dragon, causing it to no longer run in the direction of the thief.

"Well, you'd better come back!" At this time, Mina suddenly found that the hollow eye sockets of the blackened bone dragon were staring at him.

"Wait, I'll be back!" The thief also knows that the current water is dangerous.

"It's too late, I'll run away first." Shui Nai looked at the blackened bone dragon that had already rushed over, and it was too late for time, and that huge black energy claw had already come.

After Shui Nai activated the retreat, the extremely sharp black energy claws of the blackened bone dragon directly cut out four claw marks four meters deep on the ground.

Half a minute later......

"Uh, your hands?" The reappeared thief also had a way, and he couldn't help but be a little surprised when he saw that Mina's entire left hand was gone.

"It's cut, it turns out that in the state of retreat, once it is damaged, the effect will be deepened a lot, and it is a miscalculation." As he spoke, Mina activated the Light of Life with the Ring of Life, and after repairing his injuries, he suddenly set his sights on the Ring of Life.

"Youdao, take this, if I wait to use the Purple Flame Heavenly Fire and haven't killed it, you can directly activate the light of life on it, if it doesn't work, just come a few more times." Mina glanced at the bone dragon that was rapidly recovering, and couldn't help but be ruthless.

The light of life is Mizuna's life-saving move, and generally speaking, it will never be used until the end.

"Okay!"

At this time, the blackened bone dragon boss who was still guarding the altar had slowly risen to 10% of his health with the help of the necromantic breath.

"Up!" Shuina looked at the Purple Flame Heavenly Fire, which had already completed its energy reserves, and immediately rushed out, while the thief Youdao also followed.

I saw that Shuinai's purple flame heavenly fire quickly shrouded the top of the head of this blackened bone dragon boss, and the blazing purple flame actually burned the bone dragon's skull this time.

However, even so, it still failed to burn the blackened bone dragon boss to death.

And at this time, the thief also came out.

Although as soon as he came out, he was directly targeted by the blackened bone dragon, and the dragon breath in his mouth was already brewing, but as soon as the thief also came out, he shot out a light of life, and then ran to the side.

The Light of Life can forcibly correct the wrong life of the undead monster, which they have long proven.

When the light of life appeared and covered the bone dragon's body, the bone frame of the bone dragon immediately trembled, and at the same time, streams of black gas poured out of the bones, fighting against the green light that represented life.

However, the price of using black gas to resist the light of life is that the original small amount of health is immediately dropped.

"Wow, that's good! You can knock out 100,000 blood at a time, this light of life is very strong! The thief shouted excitedly as he flashed the dragon's breath that spit out, and at the same time another ray of life shot out again.

Although they all knew that the light of life could kill the undead, they did not have the luxury of using this light of life to kill monsters. And in general, there is nothing strange about it that is worth dealing with with the light of life.

"It's the last knife, so don't use props to kill." Shuina looked at the blood bar with less than 10,000 points left, and immediately reminded the thief that there was a way.

If the thieves finally use the Ring of Life to solve this blackened bone dragon, then what they get will definitely be discounted, which they absolutely cannot tolerate.

"Understood." The thief also looked at the light of life on his fingers, and became more confident.

I saw that under the activation of the thief and the dao's doppelganger technique, 9 clones from the blur to the real had already appeared, and then these clones immediately rushed to the bone dragon that was rushing over as if they were dying, and the thief also rushed forward under the repair of the light of life.

Stealth, Stabbing, Backstabbing, Strangling, Shadow Strike...... All kinds of combos and finishing moves come out from one doppelganger after another, constantly beckoning to this bone dragon.

Although such a skill is a bit like tickling for this blackened bone dragon, in terms of quantity, the thief has put a lot of effort into it.

"This guy is too hard......"

"Lao Fan, help add some auxiliary magic......"

The thieves who are fighting also have a way, shouting a few words from time to time to release the pressure that has accumulated in their hearts.

To be honest, he's nervous right now. First, this is the strongest boss he has ever faced, and second, to solve a black boss, which has never happened, at least not to the player.

And as this precious first time, God knows if the system will reward any good things!

"Youdao, your skills...... It's not very powerful! Shui Nai watched the health of this blackened bone dragon slowly recover when the doppelganger was getting less and less, and couldn't help but feel a little helpless.

The Thief's purely physical attack is completely incomparable to the defense against the bone dragon's keel.

"Help...... A helper...... "The thief who was caught off guard also has a way, and now he doesn't even have the energy to speak, so he can only keep jumping around on this bone dragon's body, dodging the bone dragon's deadly attack.

"Then you pray......" Mina finished speaking and began to attack with the Elemental Bird, but he didn't dare to open all the firepower, for fear that if he accidentally killed him, he would be in trouble.

"I'm resigned to my fate." Although the thief said so, he still thrust the dagger into the cracked skull of this bone, and caused the flame of the fire dragon dagger to vibrate.

With a "bang", the flame shock erupted directly in the bone dragon's skull, and the flames that erupted actually erupted from the bone dragon's eye sockets and ear holes.

“30253！”

At this time, a number of damage values far exceeded the normal level appeared on the top of the blackened bone dragon.

At this time, the thief also triggered a 10-fold effect of the critical hit.

"A few more times will be pretty much it, try." Mina immediately used his insight technique to check, and found that under the incineration of his purple flame heavenly fire several times, this part of the skull, which was originally the hardest, was actually burned out to a fatal point.

"Good!" The thief also understands the truth, and the ice and fire double dragon dagger in both hands dances, constantly triggering the special effect of the ice and fire double dragon dagger.

As the last trace of the bone dragon's health was stolen and the fatal blow of the Dao was stolen, the black crippled bone dragon boss also fell to the ground, and then slowly turned into a cloud of black gas and disappeared without a trace.

At this time, Minai and the thief suddenly found that they didn't have any experience.

"This is ......" Just when the thief couldn't help it, an announcement of the whole service suddenly sounded in the ears of the two of them.

"Full Server Announcement: Player Fan Chen and Player Thief also have the way to successfully kill the blackened boss 'Broken Bone Dragon' in Necronomicon Mountain, and won the title of 'Dragon Slayer', and trigger the blackened boss refresh system, the probability of blackened bosses appearing on the whole server increases, and players who kill the corresponding blackened bosses can get unique titles and legendary equipment."

"Legendary Equipment!" Mina and the thief also glanced at each other, and then they both noticed that a dazzling light suddenly appeared where the boss had fallen to the ground just now.

And then came their long-awaited experience.

I saw that the golden light on their bodies continued to flicker, and the experience slot on the attribute panel was actually growing at an extremely fast speed, and every breakthrough would bring a flash of golden light.

Mina's body flickered 5 times before stopping, and the thief also had the experience of getting the last knife, so he flashed one more time than Mina.
