At this time, the zombie boss, one foot has been blown off, in a "crippled" state, the movement speed has been greatly reduced, Feng Kai is holding a spear, and he is not fighting hard, but just constantly harassing and attacking around the boss.

Blood crows and blood zombies also pounced towards the boss, although they were not the opponents of the boss at all, they were all split in half by the boss with a sword, but they finally made their own contribution to delaying the boss's time.

At this time, the boss is surrounded by flying ice and snow, and once the blood crow flies to a distance of three or four meters from the boss, the flight speed is built, and the surface of the body will slowly condense ice.

Feng Kai saw that in his status bar, there was a "cold" bad effect, this effect level 3, as long as it was within five meters of the boss, the movement speed and attack speed were reduced by 30%, and there was a certain chance of being frozen.

Feng Kai knew that the BOSS had begun to work hard, and this state would definitely not last, his current task was not to kill the BOSS, but to stay up until Song Jian came out of the physics building, and at that time, the BOSS would naturally be cleaned up by Song Jian.

"Fight, fight, didn't I originally want to take on this boss!" Feng Kai thought in his heart, gritting his teeth and brandishing a spear to keep stabbing out.

"All of them are going to die!"

"Eight Directions Soul Slayer Sword!"

The zombie boss with a broken leg, the lower the blood value, the more courageous the combat effectiveness, I saw that it actually used the power of ice to continuously condense on the broken left leg, and after a while, a big ice lump replaced his left foot.

Although it is still not very convenient to move, at least there is no problem with turning around and moving.

"You can still do this, I said big brother, you do such a good job of prosthetics, why do you want to stay here as a boss, isn't it very promising to be a prosthetic technician!" Feng Kai complained and stepped back step by step.

More than a dozen transparent ice swords condensed above the boss's head and flew towards Feng Kai.

Feng Kai's face changed drastically, and he immediately turned around and rushed towards a small forest in front of the physics building.

These dozen or so sword moves like rattlesnake missiles couldn't be carried by Feng Kai's small body.

More than a dozen white streamers followed Feng Kai closely, as if a shark had smelled blood, and it crossed arcs in the air.

Boom boom boom~

A third of the entire forest was blown up, and the ground was bare, and the surrounding area was frozen cold, and even the big trees on the edge of the explosion were frozen by the ice, and it looked like it had entered the cold winter in an instant.

Feng Kai sat slumped in front of a broken stump, with a frightened look on his face, he had seen the boss attack Song Jian with this move before, and the movement was quite loud, but Song Jian didn't seem to have suffered much damage, but ......when it was his turn to face this move, Feng Kai now even had a feeling that he had hung up.

"It's a terrible move!" Feng Kai was afraid for a while, he was only hit by one of the Ice Long Sword Phantoms, and his qi and blood value dropped directly by one-third, fortunately, this move was a pointing skill, and it was not a lock-on type, otherwise, he might not even want to leave a complete corpse.

"Originally, I was going to single-handedly take on this BOSS...... Feng Kai felt a little pain for a moment, and originally pinned his hopes on infantry mines, but now he found that if there were no five or six infantry mines blasted together, I am afraid it would be difficult to cause fatal damage to the BOSS.

But he can only place one infantry mine at a time, which is a bit embarrassing, just like now, after the boss stepped on one, he was hurt a lot, and the hatred value was firmly locked on him, but he didn't have time to arrange the second one now, so he could only carry the boss's attack and dodge around.

After releasing two ultimates in a row, the boss also looked a little tired, limping towards Feng Kai, replacing the ice lump on his left foot, and with every step, there would be a "click" sound, leaving a puddle of fine ice chips on the ground.

Feng Kai became intimidated by this boss, in fact, he didn't have many skills, only a placement of infantry mines and a set of blue quality marksmanship.

Placing infantry mines is his core skill as a "mine infantry" class, infantry mines don't even need to be made by him, ten will be automatically generated every day, and as the level increases, the power of infantry mines will also increase, which can be said to be his most damaging attack method.

originally thought that he could kill this boss alone, but now it seems that it was just his own illusion, and Feng Kai even had an urge to turn around and run away now.

You know, although the boss's hatred value is on him, as long as he escapes a certain distance, a boss like this who has been staying in one place will not be chased all the time like that ordinary monster, and it should be easy to escape.

"Three minutes, I said that I would drag the monster for three minutes, and now it's only been more than a minute......" Feng Kai's face was cloudy, looking at the boss who was slowly walking towards him, Feng Kai shouted, seemed to have made some kind of decision, turned over and got up from the ground, held a spear, and pounced towards the boss.

Jingle Bell~

In front of the BOSS, Feng Kai was beaten and had no power to fight back, so he could only passively resist, if it weren't for the increase in the recovery speed of the qi and blood value obtained by completing the main quest, I am afraid that Feng Kai would have already cleared his qi and blood value.

In fact, Feng Kai was so desperate, not just because of the three minutes he had just taken, but because he had ambitions for this BOSS, such a strong BOSS, if he killed it, he would definitely burst into good things.

Of course, the big head will be taken away by Song Jian, but Feng Kai should also be able to share some soup to drink, if he doesn't make a little contribution, even if Song Jian gives Feng Kai the items at that time, I'm afraid Feng Kai will be embarrassed to take it.

"Three minutes, three minutes, ah~"

Rumble!

Again, Feng Kai was slashed out by the boss's sword, and his body fell heavily to the ground, feeling that the bones in his body had been shattered.

Burst~

A mouthful of blood spurted out, Feng Kai glanced at his qi and blood value, it had already fallen to one-third, such a low blood volume, if the other party released another big move, I am afraid that he would really hang here.

"Three minutes, three minutes!" Feng Kai muttered to himself, gritted his teeth again and stood up, took out a bottle of potion from the package and poured it into his mouth, and grabbed the spear tightly with a trembling hand.

At this moment, on the third floor of the physics building, a violent explosion suddenly sounded, and with a "boom", the air wave rushed out of the glass, and a figure flew out of the window, still holding an item that flashed blue light in his hand.

Boom~

Song Jian fell to the ground from the third floor, and an injury of more than sixty points floated above his head.

"Fog grass, there is even a self-destruct mechanism...... Song Jian was afraid for a while, almost this device with the "unique" attribute was about to be blown up, but fortunately, at the last moment, he blocked it with his body, and only at the last second, he put away this device.

At this time, he held a ball of light emitting blue light tightly in his hand, and in the transparent ball of light, a miniature console floated quietly in the center of the ball of light.

Seeing Song Jian coming out of the physics building, Feng Kai's eyes lit up and he shouted loudly: "Boss, help!" ”
