The task of creating the laboratory has been completed ninety percent, and all the task items are only the "polymer analyzer" in the twentieth level monster area, and Song Jian is still very satisfied with the progress of the task.

Hearing Feng Kai's shout, Song Jian first carefully put the light ball in his hand into the package bar, and then turned his head to look at Feng Kai.

Seeing the zombie boss holding a giant sword and walking towards Feng Kai who was only half blooded step by step, Song Jian shook his head slightly, stepped on the ground with his right foot, and a fang-shaped air mass quickly condensed in front of his right foot, roaring and rushing towards the boss.

A deep mark was plowed on the ground, and with a "boom", the "ground tooth protrusion" hit the boss's back, and the entire air mass exploded, like a fierce beast, biting the boss fiercely;

Caught off guard, the boss stumbled and threw himself forward.

Boom!

Another bottle of weakness potion smashed on the boss's body, weakening the defense by 35%, which is extremely deadly for the boss!

At the same time, Song Jian also used a bottle of "Salamander Elixir" on himself, and on the dark red blade, a burning flame appeared, and even the spear held by Feng Kai also appeared with fire.

Intention!

Song Jian's eyes flashed, and a huge crimson cross cursor appeared on the surface of the boss's body, and began to scan the boss's body up and down, and finally, the cross cursor stopped at the back of the boss's heart.

Eyes kill!

The vertical pupil on Song Jian's forehead slowly opened, and a dazzling silver pillar of light bloomed from the vertical pupil, shooting towards the back of the zombie boss like a laser;

Boom boom boom~

Every second, there will be a violent explosion on the back of the boss, and the damage numbers close to 100 points float up from the top of the boss's head, and in five seconds, the zombie boss's qi and blood value has dropped a lot, and finally stays at only one-third of the position.

With a terrible roar, the boss turned around, his eyes were bloodshot, staring at Song Jian, and the hatred value at this time returned to Song Jian's body again!

Bafang Soul Slayer!

With another hoarse roar, the zombie boss carried the attack hard, raised the silver long sword in his hand, and countless cold and icy air currents began to quickly condense above his head.

"Misty grass, here is this trick again!" Feng Kai's frightened face was about to change, and he hurriedly rolled and crawled into the distance, looking at the zombie boss with a frightened expression.

"What the hell did I think before, to provoke such a terrifying existence......" Feng Kai was afraid for a while.

The immortal sword body was still cooling, and Song Jian could only swing the Red Fire Heart Ape Sword and rush towards the BOSS, leaving only less than one-third of the BOSS with qi and blood value, for Song Jian, it was no different from a large gift package that walked automatically.

Dance of Folded Wings!

Bang bang bang~

The two impacts made the zombie boss's body continue to retreat backwards, and the final blow Song Jian jumped high and slashed towards the top of its head.

The BOSS let out an angry roar, and the more than a dozen ice sword phantoms above his head had not yet condensed completely, seeing Song Jian slashing towards him in the air, the BOSS suddenly felt a great threat, it swung its sword directly at Song Jian, and more than a dozen ice sword phantoms that had not yet fully formed flew towards Song Jian;

Song Jian's face changed slightly, he had personally felt the power of these ice long swords, but at this time, he was in mid-air, even if he wanted to, there was nowhere to dodge, so he could only slash at the long sword phantom;

Boom boom boom~

The three or four long sword phantoms collided with the Red Fire Heart Ape Sword, and a roar erupted, and Song Jian also suffered heavy damage.

Boom!

Song Jian's figure finally fell, and the Red Fire Heart Ape Sword in his hand and the boss's silver giant sword collided together, and a thunderous sound erupted from the impact.

A wave of air lifted the boss directly, and his body was suddenly in a floating state;

Song Jianqiang endured a mouthful of blood without spurting out, and with a wave of the long sword, three sword filaments appeared on the surface of his body, and after casting the "Sword Silk" skill, he immediately turned on the "Speed Sword" skill, and for a while, all the attacks poured on the boss like a storm.

With the move "Eight Directions Spirit Destroying Sword" just now, Song Jian endured nearly half of the Ice Long Sword Phantom, and his qi and blood values instantly slipped from nearly seven hundred points to more than two hundred points.

Roar~

A huge desert scorpion beast phantom appeared next to Song Jian out of thin air, and as soon as it appeared, its huge scorpion tail stabbed towards the boss;

Airplanes~

With a slight sword roar, Song Jian's left index finger stabbed forward, and a three-meter-long silver sword qi stabbed towards the boss's back, directly piercing its body, and the floating BOSS let out a painful roar, his face was hideous, and the green veins around his eyes bulged violently, as if they were about to burst open in the next moment.

"Die!"

The long sword burning with flames in Song Jian's hand once again pierced the back of the boss, harvesting his last bit of qi and blood value, the boss's body fell down heavily, and in the floating state, he was completely in a state of defenselessness, and all the damage received would be superimposed with the increase in the number of attacks, and Song Jian's last blow even caused a huge amount of damage of 180%.

Boom!

The boss's body seemed to be carved from ice and snow, and the moment it hit the ground, it shattered directly, and even the silver giant sword in his hand was swirled diagonally into a broken stump.

Feng Kai's gaze immediately fell on the two-handed sword that emitted silver light, and his eyes lit up.

"Like? It's yours! Song Jian glanced at Feng Kai and said.

Although his profession is a sword master, he prefers to use a one-handed sword, and he has no love for two-handed swords, and he now has a school flag in the two-handed weapon column, although the current grade is much lower than the silver giant sword, but it is a growth weapon, and no one knows where the upper limit is.

And if it weren't for Feng Kai's help this time, he wouldn't have collected all the mission items so easily, and most importantly, he saw several loot scattered next to the boss's corpse, among which was a skill scroll that emitted a silver light.

Song Jian walked directly to the boss's corpse and collected all the loot, except for this silver skill scroll, the rest were just some materials, which were not valuable.

Seeing this silver scroll, Song Jian suddenly felt as if there was an attraction, faintly calling him.

"It can't be the sword technique performed by the boss, right?" Song Jian guessed in his heart, and immediately checked the attributes of this skill scroll.

The boss's "Bafang Soul Slayer Sword" left a deep impression on Song Jian, with a short cooldown time, huge power and a group attack skill, if he can obtain such a sword technique, it will definitely increase Song Jian's strength.

However, soon, a look of astonishment appeared on Song Jian's face, and the silver-quality skill scroll in his hand turned out to be not the boss's "Eight Directions Spirit Destroying Sword", but another sword technique.
