"The attack is strong and fast, but the attack has a forward swing and can't move during that time, so it's easy to do next! Luo Tianhuan looked at his blood volume, and now he can probably support three minutes under the erosion of the GRT virus, so he must fight quickly......

Luo Tianhuan ran around the experimental field at full speed, paused after running a distance, deliberately letting the black demon attack him, and he quickly planted his own sensor mine in the short time he paused.

Luo Tianhuan has calculated that the black demon's earth-splitting heavy attack and normal attack have 0.5 seconds of pre-swing, after the attack, Luo Tianhuan wants to attack the black demon again, and it will use that teleportation to disappear. So if you want to hurt the black demon, unless you attack the black demon at the moment when the black demon attacks you, but hurt each other with the black demon, that is to find death. Moreover, the range-based skill of Earth Splitting Heavy Attack basically made it impossible for Luo Tianhuan to fight in close combat.

So Luo Tian fantasized that if he couldn't fight in close combat, and his electromagnetic dual guns were energy weapons, which had no effect on the black demon, then he would just use the induction mine to attack the black demon. The induction mine immediately explodes when it senses the surrounding enemies, and Luo Tianhuan only needs to throw it down and run away immediately.

As for Blake, who was lying in a pool of blood, there was a strange scene. Luo Tianhuan ran around the experimental field, throwing a sensor mine from time to time, and the black demon who wanted to attack Luo Tianhuan was always hit by the mine. Even if the black demon used the death spin and wanted to suck Luo Tianhuan over, he could often only absorb a few grenades and blow himself up all over his body. Then taking advantage of the interruption of the death spin skill, during the 5 seconds of the black demon's headache, Luo Tianhuan held the fire spear in his hand and burst his anus frantically. The black demon that was once regarded as a key research project in Project G by Valkyrie Labs is now being played around by Luo Tianhuan in this way, even Blake feels uncomfortable, after all, the black demon he at least thinks is his own proud work.

"Is it really because of the immaturity of the brain in childhood? Blake sighed deeply and shook his head......

"Sure enough, there are a few smart people among the virus bosses, almost all of them are as tendoned as zombies! Listening to the continuous explosions behind him, Luo Tianhuan shook his head helplessly, even if his attributes completely crushed him, he could clear the level without injury. This dungeon is not very difficult except for being infected with the damn GRT virus, and Luo Tianhuan doesn't know why so many people can't clear this dungeon at level 50......

"Boom!! Rumble!!! Rumble!!! ＂

Under a series of explosions, the black demon was blown up all over his body, although the induction mine can only blow up 2000~3000 blood, and the damage is not high, but under the continuous consumption of Luo Tianfan, even the black demon can't stand it. Using the Death Spin is also useless to Luo Tianfan, but will receive a few grenades from Luo Tianfan, and suffer miserably......

"10 seconds to go!! "Luo Tianhuan has calculated, there are still 10 seconds left before the black demon's second energy defense shield is generated, and the black demon's blood volume is not much left, before it can generate the second energy defense shield, he must kill him......

"One last time coming! ＂

The Black Demon only has more than 1,000 HP left, and it only takes a single induction mine to take it out. But instead of continuing to attack himself as Luo Tian imagined, the black demon waved his wings behind his back and rushed into the sky......

The Black Demon intends to launch an indiscriminate energy bombardment, but how could Luo Tianhuan let it succeed?

Luo Tianhuan launched a throwing skill and threw the fire spear in his hand, and that shot directly penetrated the black demon's body, taking away the last bit of blood of the black demon.

A large amount of green blood spewed out, and the black demon's body also fell from the sky, and the flames of the fire spear gradually began to consume the black demon's body......

"Ding! Kill 1 Black Demon (BOSS) and get 100,000 XP...... ＂

"Ding! Congratulations to the players for the upgrade of the Dream Bubble, which has 3 attribute points and 5 skill points that can be freely distributed...... ＂

"Ding! Congratulations to Fantasy Bubble for clearing Valkyrie Labs - Lab of Madness Nightmare difficulty and becoming the first player to clear this quest for the first time......

"Finally cleared! ＂

Luo Tianhuan sat paralyzed on the ground and gasped for breath, from the time he entered the crazy laboratory to now, it took him a total of 32 minutes and 56 seconds to clear the level......

……

At this time, the strategy group formed by the Star Guild was also attacking the copy of the Crazy Laboratory, and they also hit the final boss, the Black Demon......

"Ten thousand swords! Pay attention to protect the output! Fang Hua, you and I are pinning down the black demon! Ma Sancang, the leader of the Starry Sky Guild, yelled at his teammates beside him, this time in the Crazy Lab Four-Person Nightmare Difficulty Dungeon, the Starry Sky Guild dispatched the four strongest elite masters in the guild, including the president, and vowed to be the first to pass this most difficult dungeon at this stage. For this reason, they repeatedly watched the strategy videos of those losers and repeatedly analyzed the skills of the boss, but they only knew the first two for the boss, and they didn't know anything about the giant man-eating flower and the black demon of the last two......

But after all, they are all masters of masters, and the seamless cooperation of the team also brought them to the final boss Black Demon, and saw with their own eyes that the old man named Black was pierced by the Black Demon after throwing the weakness potion.

However, even if the black demon faced the strategy group of the Star Guild, it was choked enough, and now the black demon was also defeated by two-thirds of his blood under the cooperation of the Star Guild strategy group.

"President, it's heavenly! ＂

"Knock it down, it's about to blast with indiscriminate energy! ＂

"Ding! Congratulations to Fantasy Bubble for clearing Valkyrie Labs - Lab of Madness Nightmare difficulty and becoming the first player to clear this quest for the first time......

At this time, an announcement of a system floated over everyone's heads, and for a while, everyone in the Starry Sky Guild was stunned when they looked at the announcement of the system......

"How is that possible?! Twin Sword Flow Dream Bubble!! He's alone!! Ma Sanpao's eyes widened, he couldn't believe all this, such a difficult copy, Luo Tianhuan alone could clear the level, this is simply incredible......

And in the time when everyone in the Starry Sky Guild was stunned, the black demon's black energy ball had been condensed......

"Boom, boom, boom!!!! ＂

"Ding! Team member Wan Jiangui is dead...... ＂

"Ding! Team member Celestial Wolf is dead...... ＂

"Ding! One member of the team died overnight...... ＂

"Ding! Team Leader Xingchen is dead...... ＂

"Ding! The team was wiped out!! Task failed!! ＂
