An unexpected earthquake caught everyone in the gymnasium off guard.

Fortunately, the earthquake didn't last long, ending in just a few seconds.

What followed was the screen above the Central Martial Arena displaying scenes from downtown.

It was the perspective of a drone.

Lin Zichen looked at the screen and saw the Scarlet Giant Tree in the image, beneath which the land had collapsed into dozens of bottomless caves.

The mouths of the caves were densely packed and seemed like black holes in space that could swallow everything.

A group of well-equipped mechanically modified humans didn't dare to approach recklessly for inspection.

They only dared to release detection robots from a distance, controlling them to enter the caves to explore the depths.

The detection robots had just approached the edge of the caves.

The next second!

Dozens of pitch-black caves suddenly all burst forth with giant shadows several meters long, rushing towards the detection robots wanting to enter the caves with a "buzz."

It was just the blink of an eye.

All the released detection robots were torn into pieces by these suddenly appearing shadows.

The next second, a deafening sound of ammunition pouring resonated.

The mechanically modified humans engaged with the shadows.

However, in less than ten seconds, the mechanically modified humans on the screen were overwhelmed by the continuously emerging shadows, completely vanishing from the image.

Lin Zichen watched the familiar shadows on the screen, his expression becoming very solemn.

Giant Mutant Rats!

The shadows on the screen were the Giant Mutant Rats, missing for several years!

These Giant Mutant Rats were actually related to the Divine Plant Cult!

While Lin Zichen looked on solemnly, everyone else around him was panicking.

"How could there be so many Giant Mutant Rats?"

"It's over, Shanhai City is doomed!"

"I don't want to die yet..."

Everyone present had seen the Sakura Sea Country's rat disaster from ten years ago in video recordings and had studied it in textbooks afterward.

They knew how terrible the scene had been.

They knew how heavy the casualties were.

They knew how terrifying the Giant Mutant Rats were...

It wouldn't be an exaggeration to say that almost half of the Sakura Sea Country had been paralyzed because of it.

Now, the land where they lived was also swarming with Giant Mutant Rats, making everyone present feel somewhat desperate.

"With so many Giant Mutant Rats, it feels like Shanhai City will become ruins just like the capital of the Sakura Sea Country back then..."

Shen Qinghan pursed her lips pessimistically.

Lin Zichen offered a comforting word, "It'll be alright."

Then he stopped speaking and kept his gaze fixed on the big screen above, constantly monitoring the situation downtown.

During this time, more and more people entered the gymnasium, all looking up at the big screen above.

A few minutes passed.

The previously somewhat spacious gymnasium quickly became overcrowded.

Students with a Biological Level of Ordinary Fifth Order and above from the school had almost all gathered in the gymnasium.

They were somewhat anxiously waiting for instructions to head downtown for the rescue operation.

"President, should you organize this?"

A female mechanically modified human walked up to Lin Zichen and stopped, asking him respectfully.

She was the former student union president Zhou Xuehong's personal secretary and had now become Lin Zichen's personal secretary, providing him services and assisting in handling affairs.

Lin Zichen didn't even glance at his personal secretary and said indifferently, "Let the vice president organize it."

He had become president just to earn academic credits and had no desire to manage affairs.

"Alright, I understand."

The secretary said and then walked towards the vice president.

She had never intended to have Lin Zichen organize it; her query was simply procedural, to prevent any later complaints from him.

After the secretary left,

Lin Zichen sensed the presence of everyone present.

Almost all were Ordinary Level creatures, with less than 20 High Level Creatures.

The majority of the school's High Level Creatures had entered the Origin Land to resist the beast tide earlier.

The ones who had stayed were mainly the administrative staff.

Apart from the administrative staff, there were three High Level Experts from the student council — former president Zhou Xuehong, vice president Tan Wanyi, and the head of disciplinary affairs Han Weifeng.

"Everyone, quiet down!"

The deputy head of the Academic Affairs Office, a man whose body was covered with more than two-thirds metal, stood upright on the Central Martial Arena and loudly addressed the students below.

The students, hearing his words, immediately quieted down to let the deputy head of the Academic Affairs Office speak.

The deputy head of the Academic Affairs Office quickly got to the point, "I believe everyone has seen what's happening on the big screen!"

"Our Shanhai City's downtown area has been attacked by the Divine Plant Cult, causing a rat disaster!"

"In this critical moment, as part of the Shanhai University campus, it's our duty to go downtown for the rescue!"

"Now, please everyone line up according to your Biological Level!"

"High Level, over here!"

"Ordinary Ninth Order, over here!"

"Ordinary Eighth Order, over here!"

"..."

"Ordinary Fifth Order, over here!"

Under the deputy head's loud commands,

The students moved to their respective places, forming formations in an orderly manner.

Seeing that everyone had lined up, the deputy head of the Academic Affairs Office spoke again:

"This mission will be very dangerous, but it is also an opportunity!"

"The Giant Mutant Rats are certainly fearsome, but for us, they are a rare Evolution Resource!"

"Usually, we must evolve to High Level to be qualified to enter Origin Land and encounter so many Exotic Beasts!"
