"Prepare your weapon. We are going to slay this demon!"
ZeroCheat, XuanLake and Yunyu summoned their own weapons in response:
'ZeroCheat || Level 90 || HP 100% || Class : Tank || Passive: Light Shield.'
'XuanLake || Level 83 || HP 100% || Class : Warrior || Passive: Demon Slayer.'
'Cutiepie69 || Level 75 || HP 100% || Class : Mage || Passive: God of cute stuff!'
At this time, usually, Pupa would come to him and bicker about Yunyu's shamelessness, especially with that passive skill that he never changed. But Yunyu would usually just laughed at it, and their bicker would continue.
[Ah, dang, it's so dull without Pupa. When will he return?]
Yunyu didn't have time to ponder for too long, though. Since the Demon King suddenly summoned his minions to fight with him, three level 60 lesser demons. He jumped back and sat on his throne, waiting for his challengers to fight his minions first.
ZeroCheat looked at Yunyu and then XuanLake. They were sure that they could defeat these lesser demons without a problem. The lesser demons started attacking at the same time with their claws, XuanLake deflected the attack with his sword, ZeroCheat defended himself with his rock hammer, and Yunyu simply dodged it by flying.
However, when ZeroCheat defended the attack, he realized that his mana was chipped instead of his HP. He alerted XuanLake and Yunyu, "Be careful, these demons have Mana burn passive! All their attacks will burn your mana!"
"Yes!" XuanLake and Yunyu said in unison. They were working together in unity.
XuanLake started first by using his attack, "Blitz slash!"
XuanLake dashed and slashed his demon enemy quickly with many slashes until the demon's HP depleted to zero. It made a loud shriek before it died.
Meanwhile, Yunyu used his magic wand and chanted, "I will attack you with this!" Yunyu's magic wand disappeared as it turned into a light particle that shone on Yunyu's forehead. Yunyu picked it up with his index and middle finger, like when he was using that copyrighted Special Beam Cannon attack in world 3.
"Crescent Beam!" Yunyu pointed his fingers towards the demon. A light laser shot from Yunyu's finger, penetrating the demon's heart and killing it instantly.
ZeroCheat was the last. He spun around with his hammer and then raised the rock hammer high, "Rock Smash!"
ZeroCheat smashed the lesser demon with his attack, also instantly killed it. All of them killed the demon minions without breaking a sweat, which made the Red Demon King angrier than before. He flapped his wing and landed between them with his mace. But he didn't move. It looked like he was provoking them to attack first.
"Fine then, I will attack first!" XuanLake crossed his sword to form an 'X' and chanted, "X-Scissor!"
He charged towards the Red Demon King at high speed. The Red Demon King only glanced at XuanLake and whipped XuanLake from the side with his tail, "Argh!" XuanLake was smacked to the side as his health was chipped.
'XuanLake: HP 90%.'
"Brother Xuan!" Yunyu called him XuanLake, he wanted to help, but the Red Demon King suddenly targeted him and attacked with his mace.
"Wha—" Yunyu was shocked when the demon was so close to him when ZeroCheat suddenly jumped in and defended Yunyu with his Rock Hammer.
When the demon mace and ZeroCheat's Rock Hammer collided, ZeroCheat and Yunyu were thrown away by the shockwave, though none of them was harmed.
"Brother Zero, we need to find a way to actually hit him. He is untouchable at this point!" Yunyu said. ZeroCheat observed the Red Demon King who stood nonchalantly, waiting for another attack, then he asked Yunyu;
"Can you find a way to bind him for a moment? We might be able to attack him if he is immobile."
Yunyu nodded with certainty, "I know the tool to bind him! Please protect me when I'm binding him and let Brother Xuan attack!"
Yunyu summoned his wand again and raised it up. He waved it and chanted, "You shall not leave my chain! I summon thee, Yunyu's Love Me Chain!"
Yunyu's magic wand turned into a chain made out of golden beads that circled around him, then he pointed at the standing Red Demon King. Like a snake, the golden chain lashed towards the Red Demon King and spun around him before binding the Red Demon King completely, "Now! Brother Xuan!"
"Okay!" XuanLake got up from the ground and took a deep breath. He pointed the swords' tip towards Red Demon King and chanted his skill, "Take this, Guillotine Cut!"
Red Demon King laughed because he thought he could break free from the chain easily. But to his surprise, the chain was really sturdy. He started struggling to no avail, "ROARRGHH!"
The Red Demon King glared towards Yunyu, who still bound him. He opened his mouth and shot a dark beam towards Yunyu.
ZeroCheat immediately cover Yunyu with his skill, "Light Guardian, come and protect my beloved Yunyu!"
A light shield appeared in front of Yunyu and stopped the dark beam. XuanLake was already charging towards the Red Demon King. He finally realized that he needed to dodge this attack before he took fatal damage.
The Red Demon King tried using his tail to attack XuanLake, but XuanLake could easily dodge it since he knew the trick already. Then it started to desperately attack XuanLake with demon beams from his mouth, but Yunyu started pulling the Red Demon King left and right, so the demon beams missed XuanLake.
"ROARGGHH!!" The Red Demon King roared once more, knowing that he couldn't dodge the incoming deadly attack.
XuanLake dashed, and he cut the Red Demon King's head with his attack.
With that attack, XuanLake had successfully sliced the Red Demon King's head, and it fell on the ground. In normal condition, the monster should be dead by now, but the monster's health bar only dropped to 50%.
'Red Demon King: HP 50%.'
"As expected, he would not die so easily," ZeroCheat commented, then he ordered XuanLake and Yunyu, "Stay guarded! We don't know his next passive!"
They took a few steps back to avoid a similar situation that happened with the Lost Android's explosion.
Although it was already headless, the Red Demon King's body moved on its own and took the head on the ground. He tossed his head to the deep cliff behind his throne, and an earthquake suddenly shook the ground.
They used flight to avoid the earthquake, and slowly, a giant monster popped from the depth of the cliff.
"HAHAHAHAHA!" a burst of loud demonic laughter echoed around the cliff as the Red Demon King returned in giant form.
ZeroCheat did an appraisal of the new monster and was shocked by the change.
'Giant Demon Lord || Level 120 || HP 100% || Passive: Eternal Death || Passive 2: Great Demon Overwhelming Power.'
"Be careful, guys! This is the feared passive, Eternal Death! If you got killed by this Demon Lord, you would die for real!" ZeroCheat warned Yunyu and XuanLake. Yunyu nodded as he took it seriously.
But XuanLake grinned instead. He also did an appraisal and saw that Eternal Death passive owned by Giant Demon Lord. Then he glanced at ZeroCheat, 'It is time to kick you away from my little Yunyu's life.'
