A massive word was floating over Hasma’s head.

Mystery Observer’s mouth was gaping wide as he no longer knew how to express his current emotions.

The critical kill effect was a unique effect in > which could be triggered only if enough damage was done on the target’s vital part.

However, the critical effect normally appeared in PVP where a big name player went up against a newbie. On this situation, Wang Yu actually did this when fighting Hasma, a BOSS who was clearly at a much higher level than himself… This kind of bullsh*t was definitely unheard of.

Despite knowing how incredible Wang Yu was, Mystery Observer was still dumbstruck and tongue-tied when he saw how Wang Yu beheaded the BOSS.

What Mystery Observer did not know was that in the background story, Hasma had been beheaded by others before. Therefore, Hasma’s neck was his fatal part and it was reasonable for Wang Yu’s attack to result in such an effect.

Of course, the condition was that the perpetrator had to be one as stable, accurate and vicious like Wang Yu. Moreover, one had to be able to cause as much damage as Wang Yu could.

After killing Hasma, Wang Yu did not go ahead to the corpse to touch him like what Mystery Observer expected him to do. Instead, he jumped backwards to keep his distance from Hasma’s corpse.

Bradley resurrected twice under Wang Yu’s nose so he was naturally going to be slightly wary about this. It was always better to be more careful than careless.

Indeed, ten seconds later, Hasma’s headless corpse suddenly sat up.

Following which, he casually swung his hand and the head on the ground jumped back on his neck.

After swaying his head slightly, Hasma stood up and his HP miraculously went back to full bar.

“F*ck! How?” When Mystery Observer saw this, he couldn’t help but exclaim.

“Ai…”

Wang Yu shook his head and was about to move forward to kill Hasma once more. He wanted to test to see if this fella also had unlimited lives. However, Bradley, who had lost his targets, suddenly turned around.

He swung his staff and started executing magic skills on Wang Yu.

Wang Yu was able to take on Hasma so easily mainly due to his incredible mobility.

As a wizard, Bradley’s skills were either capable of rooting his target to the spot or slowing his target down. With such a disgusting opponent disturbing him from the back, Wang Yu wouldn’t dare to take on Hasma as fearlessly as before.

“F*ck off!”

A depressed Wang Yu cursed as he spread out his wings and flew towards the sky.

After losing their aggro target, Bradley and Hasma spun around for a while before returning to their city gate.

The aggro mechanism of these two BOSSes was enough to make Wang Yu troubled.

Normally, the aggro in dungeons will only cease after death. However, the aggro of these two brothers ceased the moment they couldn’t see their opponent… It seems like besides the fact that these two BOSSes will have a corpse after death, they were basically the same as wild BOSSes.

When the two departed spirits left, Wang Yu landed back on the ground. Almost simultaneously, the resurrected Mystery Observer, Unfathomable Mystery and Five Flagtrees walked over too.

“How? How? Is the BOSS dead?” Once they arrived in front of Wang Yu, Unfathomable Mystery asked Wang Yu desperately.

“Tsk! They’re right there!” Wang Yu lifted his finger and pointed it to the two BOSSes at the gate.

“Eh?”

Unfathomable Mystery replied, “The aggro of these two fellas seems a little weird…”

Wang Yu responded, “Right? The weirdest part is that both of them can return to life after being killed.”

“Hasma can do that too?”

“En!” Wang Yu nodded as he explained his entire encounter with Hasma.

Five Flagtree’s face turned green as she said, “Does… does this mean that we have no way of getting rid of these two BOSSes?’

Dealing with two BOSSes capable of resurrecting to full health after being killed really seems to be an impossible task.

“No way!” Wang Yu shook his head, “A friend once told me that there will never be a BOSS that cannot be killed in this game. It is more likely that we miss something… Everyone, help think if there are any points that we didn’t notice.”

“Points that we didn’t notice.”

Hearing Wang Yu’s words, everyone scratched their chin and thought about it.

From how Bradley could come back to life for the second time within five minutes proved that this was not some kind of resurrection skill. From how Hasma could also come back to life after being killed proved that this was not a question of who to kill first.

When fighting monsters capable of resurrection, the way to do it was either through the skill CD or the order of killing the opponents. The fact that these two fellas escaped these two conditions made everyone scratch their heads.

Just when everyone was cracking their heads, Mystery Observer suddenly commented, “You guys mention that Bradley revived twice?”

“Yes…” Everyone nodded.

“Then it makes perfect sense!” Mystery Observer suddenly exclaimed, “These two BOSSes are symbiotic!”

“Symbiotic BOSSes? No wonder!” Unfathomable Mystery had a realisation as he started nodding his head.

“Symbiotic? What do you mean?”

Wang Yu was confused as he inquired.

Wang Yu was still not completely omniscient to all the terminologies in the game.

Unfathomable Mystery explained hurriedly, “What we mean is that these two BOSSes cannot be killed one at a time. We have to kill both of them together!”

“That’s right!” Mystery Observer added, “Did you guys not see the talents of these two BOSSes? Live and Die Together. Perfect symbiosis!”

“So that’s what it means…”

Wang Yu finally understood after the simple explanation by the two of them.

Wang Yu had noticed the talents of these two BOSSes but because of his inexperience in gaming, he hadn’t come across too many of such unique attributes. Therefore, he didn’t give it much thought and simply thought that that was merely there to show how close the two BOSSes were as brothers.

Five Flagtree was less experienced than Wang Yu so it was normal for her to not notice this.

As for Unfathomable Mystery, this fella was only concerned and enjoying his DPS damage output. Later on, he was busy trying to run away from the BOSS so he didn’t have the time to notice that.

Therefore, Mystery Observer was the only person who noticed this.

Even after determining how the BOSS could be killed, the second hardest question would arise. How are they going to kill both BOSSes together?

From the earlier battles, it wasn’t hard to discern that both BOSSes had to be killed within ten seconds of the other. Therefore, it might not be realistic for them to lure one over to kill first.

However, taking on two BOSSes at the same time was not an easy task as well.

Without considering the possible combinations that these two closely related brothers could concoct together, one must know that both of them were elite BOSSes with high AI. When faced against a group of more than one enemy, they were certainly not going to fix both their aggro on one person.

In this sense, it might be impossible for Wang Yu to think about drawing the aggro of both BOSSes to him.

Among the four of them, Wang Yu was the only person capable of defending himself against Hasma. Additionally, the others were definitely not a match for Bradley without Wang Yu’s constant disturbance.

Switching it around, Wang Yu couldn’t deal any damage on Bradley… So if he couldn’t deal any damage, there was no way he could make both BOSSes die at the same time.

It seemed like everyone got caught up in a vicious cycle of death.
