The strange sound of "buzz, buzz" echoed in Chen Lingfeng's ears, he shook his head, and the strong white light just now made his eyes only see a faint scene.

A group of heavily armed men in black, dressed in standard gear and armed with special firearms, broke in.

"Don't move, even if you're all new humans synthesized from animal cells, I guarantee these guns can make a big hole in you." A man in black wearing a mask in the lead gestured to his men behind him, and soon the cold guns were pressed against the fireflies.

"The operation went well, as you expected, they will appear here, and it is valuable to stay here for half a month." The masked man in black reports the situation in the teleportation room to a communicator hanging from his ear.

Soon he nodded incessantly, as if the person on the communicator had already given the next order.

Taking advantage of the gap for the man in black to report the situation, Demolition quietly reached his waist and pulled out a round ball the size of a coin and held it in his hand.

"Okay, order from above, escort them out, everyone be mental, these guys are ruthless characters." The leader of the man in black turned off the communicator and gave orders to his subordinates.

Ning Yu looked around, except for Chen Lingfeng, everyone's eyesight had basically recovered. Headshot gently moved his finger at her, and Ning Yu nodded knowingly, motioning for him to take action immediately.

The man in black escorted the firefly team towards the portal of the teleportation room, and when he was about to reach the door, the blaster stealthily threw the ball in his hand into the air.

The ball slammed into the metal baffle of the wall with a crisp sound, and the men in black immediately searched around for the source of the sound, but before they could react, a large amount of smoke suddenly rose from the ball.

Immediately afterward, the blaster threw out a few more balls, and the teleportation room immediately became a pot of porridge, and the smoke drowned everyone out.

"Come over here." The sound of condensing rain sounded vaguely in Chen Lingfeng's ears, and then a slender and warm touch came from his hand, and he was immediately taken aside.

Fearing from the root of the threat to their lives, the men in black who were engulfed in smoke all gave up their previous orders, opened the safety of their guns, and fired at the surroundings.

Bullets ejected, bursts of fire from the muzzle of the gun, and only a few dark shadows could be seen swimming in the smoke in the brief illumination. Then came the sound of sharp blades tearing flesh and blood, and the smell of blood that began to spread through the air.

Death plunged the black-clad soldiers into an even more desperate panic, and the bullets rained down wildly, but in the flicker of fire, the cold metal bullets all shot into the bodies of their comrades.

The screams came and went, and by the time the smoke cleared, only corpses were left all over the ground except for the members of the Firefly Squad.

"Bang" The sound of weapons falling and running outside the portal door can be heard.

Foxfire threw his hand, and the short knife in his hand came out of his hand and flew towards the wall next to the portal door.

The blade of the knife cut through the wall as easily as if it were inserting a piece of tofu, and the footsteps outside the door stopped abruptly.

The group walked out the door, and Demolition took two weapons of the corpse in his hand.

In the corridor outside the teleportation room, the black-clothed soldier who had just taken the lead stood stunned, the short knife burning from the fox fire was across the bridge of his nose, just the right distance, and the blade was just cutting through his flesh.

"Don't run so fast, I need you to lead the way." Foxfire patted the black-clad soldier on the shoulder, smiled and pulled the short knife across his eyes from the wall.

The black-clothed soldier finally regained his strength, and reluctantly took a step towards the outside of the research institute with the firefly team.

The interior of the institute is almost intact, with all kinds of facilities such as lighting and access door locks functioning normally, except for the empty and relatively old ones, which are indistinguishable from the previous institutes.

Everyone turned through many mechanical induction doors, and finally reached the exit of the research institute, Ning Yu turned around and motioned for everyone to slow down.

"Tell me, who ambushed you here?" Foxfire kicked the black-clad soldier leading the way in front of him.

Before the black-clothed soldier could reply, a needle was nailed to his forehead at a rapid speed, and some blood-red liquid was injected into his body.

"Don't ......" the black-clothed soldier spat out two words in pain, and then his body began to twitch uncontrollably.

"Blast, shoot at his heart, be fast, don't wait for him to mutate!" Ning Yu watched as the black-clothed soldier lay on the ground twisted, and immediately let the blast press against his chest and shoot him.

The special bullet "Bang" opened a large hole in the chest of the black-clothed soldier, and his body immediately stopped twitching, and on closer inspection, his arms and face had begun to change rapidly, and it was expected that if he was not killed in time, he would soon become a mad beast.

"Come out, don't hide anymore, do you think that after so long, we will forget about you, or are you testing something." Foxfire shouted in the direction of the exit of the institute.

"Oh, I said Miss, do you welcome your old friend in such a tone?" At the exit, a slender and slender man walked slowly.

With a pair of small, round-rimmed glasses perched on the bridge of his nose, a gentlemanly and elegant smile on his face, his hands in the trouser pockets of a tailor-made black evening gown, and his gestures were elegant and aristocratic.

"Disgusting guy, although you are my type from head to toe, only your brain, which is full of extremely distorted and perverted ideas, makes people not interested in anything." The fox pressed his hand to his chest and vomited.

"Really? I always thought we were going to be a good match. It seems that you are better suited to stay in those solutions that cool your organs. The man stopped, put his hand over his face, revealing only one eye, and began to laugh maniacally.

"Doctor, you haven't changed at all." Ning Yu indifferently drew his long sword and prepared to attack.

"Let... I'm coming, I'm ... Always... Very... Hate him. Blade stood in front of Ning Yu and pulled out the twin knives at his waist.

"Hahaha, isn't your stammering problem still cured?"

"Multi-piped... Business! Blade spat out, and rushed towards the doctor like a ghost.

The doctor put away his smile and looked at the rushing blade, he didn't intend to meet it, but retreated sharply.

Blade didn't think much of it, and followed the doctor's footsteps out of the institute.

Two figures rushed out of the institute, their blades moving faster, catching up with the retreating doctor, their knives flying and slashing at the doctor's throat.

The Medic just smiled, twisted his body in mid-air, and dodged the blade's attack.

Blade was about to continue his offensive when a huge black shadow flashed in front of him.

In the next second, he couldn't see what was hitting his chest at a very fast speed, and the blade didn't have time to dodge and block, only to feel that his chest was like hitting a hard boulder, his throat was sweet, a mouthful of blood spurted out, and the whole person fainted with a muffled snort.

The crowd heard the snort of the blade and hurriedly followed it out of the institute.

Ning Yu felt apprehensive in her heart, she was clear about the blade's ability, but the other party could make him faint to death with one move, which showed that the enemy hidden in the dark was not easy to deal with.

The long sword was unsheathed, and the sword strike condensed with frost energy slashed into the air towards the black shadow that hit the blade.

"Bang" Before Sen Han's sword strength entered the black shadow's body, it was shattered by another powerful impact slam.

Ning Yu was keenly aware that something was entering her body.

The long sword then reversed, stabbing into the void to shatter the power of the sword.

The "snap" long sword hit accurately, but Ning Yu's hand did not come with the touch it should have, but the powerful force seemed to firmly absorb the sword body, almost making her unable to hold it.

Gradually, Ning Yu saw the true body of the powerful force clearly.

The moment he touched the other party's gaze, Ning Yu, who was as calm as water, had a frightened expression for the first time, his eyes were wide open, his long sword was finally taken off, and the corners of his mouth trembled and squeezed out two words.

"Instructor!"
