When Ye Fei stood up, the time had already started the countdown, and at this time, he heard the sound of a rope around him, as well as the harsh sound of metal rubbing.

Looking towards the iron gate, Ye Fei almost didn't burst out of his foul mouth.

I saw that the door was surrounded by countless biochemical monsters, and I could only see the human head stirring. And the plug on the door has actually cracked, and the crack is gradually expanding, as if it can collapse at any time.

couldn't care so much, Ye Fei directly took out the Star of Hope, and he found that this gun could be used in this copy, which saved a lot of effort.

Rushing forward, he shoved the barrel of the gun through the metal door and window, and pulled the trigger on the group of biochemical monsters.

This group of biochemical monsters is diverse and varied. There are very ordinary biochemical zombies, as well as very fast mutant zombies, which are also bloody zombies. There's even the Little Hulk, the Pterodactyl Ripper, the Swift Bug, and more. There are too many, and the door has been blocked tightly, and Ye Fei can't see how much there is outside.

The metal door clanged, and the claws of countless zombies slashed across it, making a piercing grinding sound.

Fortunately, I can accept it, if a timid girl comes to do this task, I'm afraid I will be scared to cry directly.

The star of hope in his hand decisively pulled the trigger, the muzzle of the gun burst with purple flames, and bullets came out of the chamber and swept towards the group of biochemical monsters like raindrops. Since there are so many monsters, there is no need to deliberately aim at all.

The bullet hit them, blooming a green blood mist, because the Hope Star gun has additional attribute bonuses for biochemical monsters, and various attributes are also quite strong, each bullet hit them is a big blood hole. The minced meat flew sideways, and in that kind of scene, just by looking at Ye Fei a few times, he felt that his internal organs began to churn, especially his stomach, and he almost didn't squirt out his dinner.

Bite! Kill a biochemical zombie and reward 30 XP and 2 GP points.

Bite! Kill mutant zombies to reward 40 XP and 5 GP points.

Bite! Kill a Crimson Zombie and reward 100 XP and 20 GP.

Bite! Kill the Hulk and reward 150 XP and 30 GP.

……

It's easy to deal with these guys, but the reward is a bit of a pain, barely enough to cover the ammo.

The Star of Hope was so powerful that it quickly cleared a large area of the doorway. Ye Fei turned on the grenade mode, and there was a round of bombardment in the biochemical monster group.

The grenade also has an additional damage stat bonus, which is comparable to that of a high-explosive grenade. A grenade passed, killing and crippling. Another shot passed, and all the blood was lying on the ground.

It doesn't feel very cool, switch to machine gun mode, and it's a wild sweep against that group of residual blood.

Looking at the various experience point rewards and GP point rewards that were swiping wildly all over the screen, Ye Fei felt very refreshed in his heart, it was simply a feeling of drinking too much.

The golden light floated up from his body, and it was actually upgraded.

Bite! Congratulations on your promotion to Captain 2

The experience was brushed too fast, and Ye Fei's eyes were also flashing, it was so cool to brush experience here, and with this metal door separating it, those biochemical monsters couldn't rush in at all.

After 15 minutes, Ye Fei felt that something was wrong.

You must know that this task is limited, and it is very cool to farm monsters, but the task is to let him clear the level within two hours. And those monsters outside the door seem to be endless, even if they are brushed to death, I am afraid they will not be able to finish brushing.

Get out! You have to kill it!

Patronizing the monster farming, Ye Fei noticed that there was a blue light dot in the upper left corner of the screen, which was the coordinates of the task point.

Get out! Gotta get out!

At this time, Ye Fei saw that the door plug was shiny, stepped forward and clicked the E button, and the metal door opened with a bang, and those biochemical monsters poured in like a tide.

Ye Fei directly switched to grenade mode and slammed the trigger at the door. You must know that the grenade of the Hope Star has a knockback effect, and after killing a biochemical monster with a grenade, it can return 10 points of blood, this attribute is simply an anti-heaven existence in the biochemical challenge mission.

However, just in case, Ye Fei still used a large treatment package, so as not to have any accidents.

Several grenades flew towards the door, exploding a large open space in an instant, Ye Fei directly switched to machine gun mode, and rushed out with the Star of Hope. This bolt machine gun mode and grenade mode are used interchangeably, and there is no need to replenish ammo at all, and there is nothing more cool than this.

Killing a bloody path, Ye Fei almost stepped on the corpses of countless biochemical monsters and rushed out. At this moment, the group of biochemical monsters behind them chased after Ye Fei as if they had been stimulated.

Ye Fei jumped backwards while firing wildly at the group of biochemical monsters. Bullets rained down, and in an instant, a large piece was brought down, and the XP points filled the entire screen.

There was a narrow doorway in front, and Ye Fei went straight into it. It was a narrow corridor with many rooms next to it. From time to time, biochemical monsters will rush out of the room, especially those small Hulks, which will instantly accelerate towards you, extremely fast, and not easy to dodge.

Ye Fei was punched twice by the little Hulk, and his health dropped by a large margin. But fortunately, there is a grenade, and if you go to the monster and shoot a grenade, your health will be full again.

Rushing down the narrow hallway, a hall appeared in front of me. Ye Fei had just entered the hall when a metal door suddenly came down, closing the passage just now.

The entire hall is surrounded by thick walls, and it is impossible to tell where there is a passage.

And there were four large pools in this hall, which were full of green liquid, bubbling and bubbling, and green smoke rose and spread out in all directions.

The room was silent, save for the gurgling of the pool. Ye Fei's face became solemn, because 25 minutes had passed since the countdown above, and there was still an hour and a half left, and he still had an ultimate boss to fight, which was difficult to think about.

At this moment, Ye Fei obviously felt the ground tremble, and four huge bodies crawled out of the pool.

It's the Misty Ghost!

However, the misty ghosts in front of them were different from other misty ghosts, their bodies were covered with green slime, and bursts of dark green smoke were released from their bodies, which looked very strange and terrifying.

Poison Mist Ghost (Premium Boss)

Health: 50000

Armor: 60

Additional Attribute Toxic Mist: Unleashes a toxic mist that deals 5 damage per second to nearby players. (Poison Mist does not stack)

Four high-level bosses! Four poisonous mist ghosts!

When Ye Fei saw these four guys, he only felt a chill down his spine, and cold sweat broke out......
