Just when Yan Fei was planning to gather an army and go straight to the Golden Triangle, news came from Liu Yun's side that something was wrong in the Ten Thousand Demon Cave.

"What's the situation?" When Yan Fei came to the Ten Thousand Demon Cave, he found that everyone had stopped farming monsters, staring at the giant sinkhole in a daze.

"See for yourself." Liu Yun pointed to the pit and motioned for Yan Fei to take a look for himself.

Yan Fei raised his eyes and saw that the undead monsters that were dense before had actually disappeared, and a strange large-scale formation appeared in the Ten Thousand Demon Cave at some point.

And at this moment, this weird large-scale formation was emitting scarlet blood light, and the corpses of the surrounding undead creatures were constantly floating out of blood, flocking towards this big array one after another!

Watching thousands of bloodshots flutter in the air, and finally merge into the big array, and after the weird big array absorbed these bloodshots, the scarlet light became even more enchanting! Yan Fei only felt that his scalp was numb, and his whole person was enveloped by a sense of unknown fear.

"It's not right, everyone be prepared! Then send an order to all the elite legions in the alliance and let them hurry here! Yan Fei had to give the order to gather people.

It didn't take long for the elite fighters of the entire Huaxia Alliance to arrive here in a teleportation array, and Yan Fei immediately arranged defensive tactics.

When the time came to night, the strange array was still absorbing those blood threads, and when a ray of moonlight shone on the center of the array, the situation changed.

The strange array in the Ten Thousand Demon Cave shot out a scarlet blood light, directly dyeing the moon in the sky red! Immediately after, a huge figure came out of the big array!

"Ding! The system announced the whole world, the first world boss, appeared in the XXX point XXX position in Asia! ”

"Ding! Kill the world boss to get great rewards. ”

The announcement of the system took everyone by surprise, grandma's! It turned out to be a world boss, and this time it's going to be a tough fight.

At the moment of the mind, the information of the world boss appeared in Yan Fei's mind:

Undead God of War: Level 80 diamond boss, one of the world's bosses, gathered the lifeless aura of tens of millions of undead creatures, ferocious, bloodthirsty, and irritable.

Health: 100000000, Mana: 50000000, Very High Physical Defense, Very High Magical Defense, Very High Physical Attack, Very High Magical Attack.

Skills: 1. Consecutive slashes. 2. Magic cannon. 3. Ten Thousand Bones Sword Technique. 4. Magic Sound Tides. 5. Ten thousand bone shields. 6. Cold fire of dry bones.

Special skills: 1. Summons an army of the undead. 2. Demonization.

Facing this world boss with a health value of 100 million, Yan Fei gritted his teeth and quickly ordered: "All MT will surround me, take turns to resist the boss, and all the treatments will give me a good idea of MT's HP!" The rest of the people give me crazy output! ”

"Boom, boom!" The MT army rushed towards the boss and surrounded it.

"Roar!" The undead god of war roared angrily, swung his greatsword, and unleashed a combo slash skill at an MT in front of him.

Depend on! So the perverted attack? This MT only resisted 2 swords, and his health dropped by half!

"MT opens the damage reduction skill to resist the boss, and as soon as the damage reduction skill time passes, immediately replace the person to continue to resist!" Yan Fei made tactical adjustments.

"Shield Wall!" The MT immediately opened the shield wall, and at the same time, the nurse's healing skills also fell on his head, and his health finally increased a bit.

"Boom, boom!" Countless magical attacks bombarded the undead god of war, and the undead god of war did not float out of the dense damage value above his head.

"Attention! As soon as the boss opens the group skill, everyone hides for me, it's important to save my life, this is not a copy, it's not a secret realm, and if you die, you can't be resurrected! Yan Fei reminded loudly again.

Hearing Yan Fei's reminder, everyone also became cautious, and those melee professions didn't dare to get close to the boss!

"Listen up to all melee classes, when the boss summons the army of the undead, you just have to concentrate on dealing with these mobs, and the rest of the ranged output professions will attack the boss with all your might!" As soon as Yan Fei gave this order, the undead god of war raised his head to the sky and roared, and countless undead armies came out of the ground around him!

"Kill!" I don't know who shouted, and all the melee professions flocked to the army of the undead, and a big battle immediately began.

"Roar!" The Undead God of War roared again, and countless bone swords appeared in the sky, and in the next second, these bone swords centered on the Undead God of War shot towards all directions.

"MT dodge skills, if you can't dodge, open damage reduction skills to resist!"

"Heal is optimistic about your chosen MT, and the skill casting speed must be fast!"

"Stay away from the ranged profession, wait for the boss skill to pass, and then follow up and output!"

......

Yan Fei carefully observed the battlefield while making tactical adjustments, and at the same time, the attacks in his hands were not slow, and one spell after another kept throwing towards the boss.

When the boss's health drops to three-quarters, the creature frantically uses magic crowd damage.

"Boom, boom!" Under the bombardment, hundreds of MTs fell to the ground, Yan Fei's eyelids jumped, and he made adjustments again.

"Leave the MT above level 75, and return the rest of the MT!"

"Bang bang bang!" The MT that surrounded the boss instantly withdrew more than half, leaving only some powerful MT with a higher level and no lower defense left by the boss's side.

"Roar!"

The undead god of war summoned four green flames, these flames kept rotating around him, and anyone who was touched by the green fire automatically burned green flames on their bodies, and at the same time, their health dropped wildly!

"Rub! Heal the profession with a dispel skill, MT who is hit by the flame quickly leave, this flame will be contagious! After seeing that the green fire burned a piece of MT, Yan Fei had to order to adjust his tactics again.

"Brother Fei, no, the boss is too perverted, MT can't bear it!" Li Li shouted in front.

"All healing professions, in five batches, take turns using group healing skills!" Yan Fei saw that the MT legion in front of him was in a hurry, and immediately ordered the healing profession to brush up the team's blood volume.

The scene gradually stabilized, and the health of the undead god of war continued to drop, and in less than an hour, it fell to less than half.

"Roar!"

This time, the undead god of war directly summoned a bone shield to protect himself, and his defense instantly skyrocketed, and everyone's attacks became more and more difficult.

Yan Fei shouted anxiously: "All the armor-breaking and demon-breaking skills are used for me, and strive to quickly break the boss's bone shield!" ”

"Boom!" Whether it's MT's armor-piercing skill or the ranged class's demon-breaking skill, they all throw it towards the boss, and the health of the undead god of war drops down again.

When the health of the undead god of war dropped to only a quarter, it went berserk and used three skills at once, Ten Thousand Bones Sword Technique, Demon Sound Tide, and Dry Bone Cold Fire.

All of a sudden, Yan Fei's army was beaten, and the original battle formation was suddenly chaotic......
