Reborn as a lotus, she initially refuses to hand it over to the state.

Just as he finished speaking, a window of a dilapidated house was suddenly broken open, and more than a dozen polluted rats rushed out at the same time.

"Fire!"

Gunshots rang out, several contaminated rats were blown apart, and more contaminated rats poured out from all directions, the students' faces turned pale.

Su Wan coldly ordered, "Proceed in groups!"

The battle erupted instantly. This time, Jiahao didn't rush in recklessly. He gritted his teeth and controlled the flames to attack only the most densely packed areas of the rat swarm.

Lin Qingxue followed behind, taking charge of treating the injured students.

A student was bitten on the arm by a contaminated rat, and the wound quickly turned black.

Lin Qingxue's expression changed, and a blue light fell from her palm.

The black energy was forced out.

The student was sweating profusely from the pain, but thankfully his arm was saved. Su Wan was moved by this scene, never expecting that Lin Qingxue's ability could suppress the pollution.

This battle was destined to be anything but easy; there were simply too many contaminated rats.

Undeterred by death, they attacked humans relentlessly, and soon everyone was forced to retreat to an open space at the village entrance.

Just then, a sharp hiss suddenly came from the direction of the abandoned well, and all the contaminated rats stopped moving at the same time.

Then, they parted to the sides like a tide.

A giant rat king, nearly three meters in size, crawled out of the abandoned well.

At the peak of the third tier, Su Wan's expression changed drastically: "All students, retreat!"

The polluting aura emanating from the Rat King was far stronger than that of ordinary polluted rats.

As soon as it appeared, several psychic students turned pale, and it sounded like countless screams were ringing in their ears.

Su Wan gripped her longsword, preparing to take action herself, but the Rat King was extremely fast.

It suddenly leaped and pounced directly on the student who was most seriously injured.

Lin Qingxue's expression changed drastically: "Get out of the way!"

However, the student was already terrified.

The Rat King pounced so fast that its massive body almost became a black shadow, reaching him in the blink of an eye.

At the critical moment, Su Wan suddenly rushed out, holding her long sword horizontally in front of her.

The Rat King slammed down with its paw, causing the blade to tremble violently.

Su Wan was so shocked that she staggered back more than ten steps.

Although the student wasn't directly attacked by the Rat King, he was thrown away by the shockwave and slammed hard against the abandoned wall.

He screamed in agony as his right arm twisted at an unnatural angle.

"Zhao Feng!"

Several students turned pale instantly and gasped in surprise.

Lin Qingxue rushed over and the blue light from her palm landed on Zhao Feng's arm.

Her expression changed very quickly.

On Zhao Feng's wound, there was not only a fracture, but also a black scratch.

The black aura was spreading upwards along the flesh and blood.

Lin Qingxue gritted her teeth and activated the cyan spiritual power within her body to forcefully suppress the pollution.

Zhao Feng was in so much pain that he was covered in cold sweat and his lips turned purple.

"Don't let me become a monster."

Lin Qingxue's heart skipped a beat, and she said, "No, you can hold on."

Meanwhile, Su Wan was already facing off against the Rat King.

With a single, sharp slash, she tore a wound in the Rat King's shoulder.

This rat king is nothing like a normal veterinarian; it has no sense of pain and is too lazy to even dodge.

After the flesh was cut open, a clump of wriggling black flesh was revealed inside.

Su Wan's eyes darkened, and the Rat King let out a sharp screech, the sound reaching everyone's minds.

Several psychiatric students immediately knelt on the ground, covering their heads with their hands, blood flowing from their ears.

"what!"

"Something's calling in my head!"

"Shut up, shut up!"

One of the boys' eyes instantly turned bloodshot, and he suddenly raised his hand, delivering a mental shock to his teammate next to him.

The teammate was caught off guard and was so shocked that his mouth and nose bled.

Su Wan's expression changed drastically: "All mental damage dealers, withdraw from the battlefield! Healers, protect the wounded! Melee fighters, hold them off with me!"

The ninth inning team members, who arrived one after another, immediately filled the defensive line, and a major battle was about to break out.

Abandoned villages were completely transformed into battlefields.

Jiahao stood in the crowd, his face pale. He had always thought that his fire-type ability was very strong.

But seeing the terrifying pressure emanating from the Rat King, he realized that his own strength was nothing at all.

At this moment, a dozen or so contaminated rats pounced from the side, bypassing the main battlefield and rushing directly towards the injured student.

Jiahao's pupils contracted. He subconsciously wanted to set a large-scale fire, but then he suddenly remembered Su Wan's words from before.

If you misuse your abilities, you'll kill someone.

Jiahao gritted his teeth and forcefully suppressed the spreading flames.

He raised his hand, and the flames condensed into several tiny rockets, which he aimed precisely at the swarm of rats.

Boom boom boom!

Several polluted rats were pierced by the flames, and the remaining few rushed forward but were killed by the other students working together.

Jiahao was panting heavily, his face ashen. This time, he had no mood for smugness; the battle was becoming increasingly fierce.

The swarm of rats seemed endless.

Pollution rats are scurrying out everywhere, from beneath abandoned houses to ditches and cracks in walls.

Some students were bitten on the calves, and a member of the Ninth Infantry was tackled and almost had his throat torn open by the rats.

Su Wan was held back by the Rat King and had no way to break free.

She already had several wounds on her body.

Although none of them are fatal, the dark energy is constantly eroding the wounds.

While treating Zhao Feng, Lin Qingxue also had to help others suppress the pollution, and her face grew paler and paler.

Her spiritual energy was being depleted too quickly, and she dared not stop. If she did, those bitten by the contaminated rats would likely be completely corrupted by the contamination.

Suddenly, a roar came from the direction of the abandoned well, and the ground began to shake. The cement ground around the abandoned well in the center of the village cracked inch by inch.

A large amount of black gas gushed out of the wellhead. As if stimulated, the Rat King suddenly let out an even sharper screech, and all the polluted rats instantly became even more frenzied.

Some of the contaminated rats even self-destructed, exploding into large plumes of black blood mist.

"Retreat!"

Su Wan's expression changed drastically; she finally realized something was wrong.

The rat king is not the source, nor are these polluting rats. The real source is beneath that abandoned well.

The wellhead completely collapsed.

Black smoke shot into the sky, and deep inside the well, a narrow black crack was revealed, from which came a dense, scratching sound.

Su Wan felt a chill run down her spine: "Contact the branch immediately! Contaminated cracks have been discovered in the abandoned village. Requesting backup!"

Just as the correspondent was about to respond, the Rat King pounced, its target not Su Wan, but Lin Qingxue.

To be precise, it was the cyan spiritual energy in Lin Qingxue's palm.

That power could suppress pollution, and to the Rat King, it was like a natural enemy.

A mad, venomous glint flashed in the Rat King's eyes, and his massive body lunged forward.

"Lin Qingxue, watch out!"

Su Wan's expression changed drastically, but she was too far away. Jiahao gritted his teeth and rushed out, his hands bursting with flames, blocking Lin Qingxue's path.

"Get out of here!"

The flames slammed into the Rat King's face. The Rat King's body only paused for a moment before it slapped down with its claws, sending Jiahao flying. His clothes ripped open at the chest, and blood gushed out.

He fell heavily to the ground and couldn't get up for a long time.

Lin Qingxue's pupils contracted. This time, she did not choose to leave the group, but gritted her teeth and released all her cyan spiritual power.

On the ground, several green vines broke through the soil and tightly wrapped around the rat king's forelimbs.

However, the gap between the two sides was too great, and the green vine only lasted for less than two seconds before it was forcibly torn off by the Rat King.

Just as the Rat King was about to pounce on Lin Qingxue.

A furious roar came from afar.

"You beast, you're asking for death!"

A figure rushed into the battlefield from the village entrance; Lu Cang had arrived.

His entire body erupted with spiritual energy, and he was like a long sword drawn from its sheath, instantly crashing into the Rat King.

The Rat King's massive body was sent flying, crashing into and collapsing a mud wall.

"Captain Lu!"

Su Wan breathed a sigh of relief.

Lu Cang's face was gloomy. He glanced at the tragic battlefield and then looked at the black gas that kept surging from the abandoned well.

"You take the students and evacuate first; leave this to me."

Su Wan gritted her teeth: "This is no ordinary rat swarm; there are contaminated cracks at the bottom of the well."

Lu Cang's eyes darkened: "I saw it."

The next second, the Rat King rose from the ruins once again.

Its shoulders were sunken and half of its face was charred by flames, yet its aura became even more ferocious.

Lu Cang brandished his longsword: "All students evacuate. Ninth Bureau Combat Team, stay behind and seal off the abandoned well."
