As soon as they entered the infirmary, several people smelled a sweet and greasy smell.

On the opposite side of the door, against the wall, there was a tall iron shelf, on which were neatly placed more than a dozen glass jars with a diameter of one centimeter, and inside were all citrine beetles with golden appearances.

There is a laboratory table by the window, on which a green reagent is placed in addition to various instruments.

Veterinarian Zhang glanced at a few people carefully, and suddenly remembered something, pointed at Tianling and asked hurriedly:

"You guys, you're not infected, why are there so many injuries on this guy's body!"

Brother Haoran was anxious, and hurriedly replied:

"It's okay to go downstairs and fall! What about the antidote, is it this on the table? Take it, farewell! ”

Before Brother Haoran grabbed the reagent with his hand, the bald veterinarian snatched it and said prominently:

"Hehe, I want it, but after I experimented countless times, I finally succeeded in making it, do you know why they attack humans like crazy after they are infected with the citrine virus?"

The four of them were obviously a little impatient, and even Liu Suifeng, who had always been calm, involuntarily lifted the curtains frequently and looked out, but they also knew that if they didn't let Veterinarian Zhang finish speaking, he would not be willing to hand over the reagents, so they had to listen patiently.

Because Zhou Muyan is also studying medicine, she asked curiously:

"Maybe it's because you're hungry, and when you get infected, you really want to eat meat?"

Veterinarian Zhang showed a mocking expression, shook his index finger and said:

“No！ It's for breeding! ”

"Breeding?"

"That's right, if it's because of hunger, then why don't they attack anymore after humans are infected with the citrine virus? They breed by attacking and grow their families until the whole world is ruled by the Citrist!

So, you have to stop them, these citrists only follow the instructions of the pathogens, as long as they get rid of the pathogens, it's all over..."

Hearing this, Zhou Muyan nodded suddenly and said, "Isn't the principal here the source of the disease?" Let's go together! ”

Veterinarian Zhang shook his head: "I won't go with you, as a researcher, I will never rush to the front line, the whole body of the pathogen body is covered with crystal armor ten times stronger than ordinary citrine beasts, if you want to kill it, you must use this!" ”

Shaking the green reagent in his hand, the veterinarian continued:

"You have to find a way to pour this tube of reagent into its mouth, the potion can suppress its desire to reproduce in a short time, so that it will lose the idea of attacking, and the crystal armor on its body will become fragile, take this opportunity to solve the pathogen."

After speaking, Veterinarian Zhang solemnly handed the reagent into Brother Haoran's hands, and added a sentence in his mouth:

"Don't be mentally burdened, he's not a good principal anyway."

[Main Quest Update: Kill the source of infection.]

Reward: One attribute point, those who successfully use potions on the source of infection will get an extra black star! 】

Put away the potions they got, and the four of them hurriedly walked out, and only then did they leave the infirmary, and a prompt sounded -

[Member-unpleasant has died]

"Let's go!" Liu reminded with the wind and ran towards the teaching building as if flying.

After a while, sure enough, many citrine beasts had already begun to return, and when they saw the four of them, they roared and surrounded the teaching building!

Fortunately, a few people had already arrived at the back door of the teaching building, and two citrine beasts that came in from the front door were also cut down to the ground by Tianling, with the blessing of willpower, plus the fifteen% attribute added by the totem of the [Eternal Lighthouse], it was very easy to cut down ordinary citrine beasts.

Tianling guiltily glanced at the school gate along the wide open front door, only to see that the originally verdant lawn had been trampled into a mud, and on the mud, there was still a ...... A puddle of flesh and mud, and you can vaguely make out the broken punk coat on the mud.

The poor girl didn't know until she died, but at least two of these people could save her.

A gray corpse dog rushed over, and Brother Haoran stood at the corner of the stairs and shouted:

"Tianling! What are you doing in a daze, come up! ”

Only then did Tianling retract his mind and run upstairs.

"Phew!"

Liu Suifeng closed the electronic door with the wind, drew his sword and slashed the door lock, and the electronic door was damaged and made a "Didi" sound, which once again triggered the protection mechanism inside the door and blocked all the citrine beasts from the outside.

The four of them breathed a long sigh of relief, did not dare to stay all the way up to the third floor, looked at the principal's office with double doors at the end of the corridor, and walked slowly and vigilantly.

Bypassing the corpses of the citrine beasts all over the corridor, before everyone could reach the door, the door of the office was pushed open from the inside!

A bewitching figure walked out of it with a twisted ass, followed by three men in white shirts, these four citrine beasts seemed to retain some sanity unlike the others, and did not pounce directly, but strode with a cruel smile.

Not only are they covered with thick crystal armor, but they also have long crystal spikes on their shoulders and elbows, and the crystal spikes on their claws are much longer than those of other citrine beasts.

The female citristine beast at the head opened her large mouth, the corners of her mouth grinning upwards to the base of her ears, and licked two rows of sharp teeth with her scarlet tongue.

"The corridor is too narrow to be opened, Tianling, Zhou Muyan, leave it to the two of you here, Haoran and I will go first to meet the source of the disease for a while!"

Liu Suifeng explained and rushed over with Brother Haoran, the female citrine beast kicked on the ground with her legs, her left arm was in front of her, and she used the crystal blade on her elbow to crash into Liu Suifeng who was running in front!

Liu Suifeng pretended to block but dodged, and with the help of Brother Haoran's corpse dog, the two broke through the block and successfully entered the principal's office.

The female citrist beast pulled out the crystal blade embedded in the wall, and did not pursue, and the other three citrine beasts surrounded Tianling and Zhou Muyan.

"I'll leave it to you, girl!" Tianling and Zhou Muyan confessed, and then took the lead in attacking!

The two male citristine beasts also set off, one left and one right, and grabbed them in a flanking attack! Tianling squatted down without panic to dodge, his claws brushed his scalp and skimmed, and he directly shaved his head!

At the same time, another male citristine beast stretched out his arms to smash his head, Tianling raised his knife and stabbed it in the abdomen, and a metallic sound came out, although it did not hurt it, but it also pushed it back a few steps.

Tian Ling followed up with the two-step long knife and stabbed again, this time the wrist was raised, and the tip of the knife pierced the throat of the citrine beast, and the elbow was raised upwards and then pressed down hard, nailing it directly to the ground!

Immediately after the sound of breaking wind behind him, Tian Ling didn't have time to completely dodge, three long cuts were drawn on his back, and the corners of his mouth twitched quickly a few times in pain, and he turned around to fight with the remaining two citrine beasts!

On the other side, the female citrine beast that Zhou Muyan faced was extremely fierce, continuously turning her body and sweeping it with the crystal blade on her claws!

Zhou Muyan was helpless for a while and was forced into a corner, and she was about to be torn apart by the crystal blade that came over!

At that moment, she suddenly looked down at the feet of the female citrine, and immediately leaned over and kicked the spinning citrine's feet.

A trace of astonishment flashed in the eyes of the female citrine beast, and the rotating body suddenly stopped and fell to the side, and before she could react, she was pressed to the ground by Zhou Muyan, who pounced on her, and her red palms slapped its face mercilessly, and she scolded fiercely:

"You still wear high heels when you fight, you can't die!"
