Don't try to cultivate immortality; mortals live longer than immortals.

Soon, the helicopter door opened, and several figures dressed in special operations uniforms came into view. Each of them was muscular and looked very tough.

But what's even more striking is the oppressive aura emanating from them.

The spiritual energy fluctuations are equally powerful!

"Golden Core Stage!"

"They are powerful members of the Demon Suppression Army!"

Soon, people below recognized their clothes.

The Demon Suppression Army is the top combat force of the Immortal Alliance!

Today, Guixu is still able to enjoy a peaceful and comfortable life, not only because of the "Qiankun Hunyuan Protective Array" left behind by Lin Tianzun, but also because of the arduous and extraordinary battles fought by the warriors sent by Guixu and its affiliated interfaces in the outer orbit space.

They formed various legions to withstand dangers from all directions.

The Demon Suppression Army is one of the best among them, with outstanding military achievements over the past two thousand years!

Leaving aside the college students, even Duan Xuan felt that these cultivators in front of him were different from the teachers he had met before.

Although the teachers at Shuiyun Daoyun Academy, the highest institution of learning on Mercury Star, are mostly at the Golden Core stage, even if they are at the same level, their strength is still significantly weaker than that of the cultivators in the Demon Suppression Army.

This is not to say that the teachers are weak. On the contrary, their basic skills are very solid, and the power of their cultivation techniques and treasures is extraordinary.

However, there are some things that cannot be remedied simply through cultivation.

At this moment, these warriors from the Demon Suppression Army exuded an inexplicable aura.

It's hard to say whether it's oppressive aura or malevolent energy.

But one thing is certain: they are not to be trifled with; each of them is a veteran of countless battles.

"Hello, fellow students. My name is Zheng Lei. As you can see, my comrades and I are all members of the Demon Suppression Army."

"Over the next few days, I will be your instructor, and your mission this time is to go to a cultivation world called Azure Sky."

"Now let me give you a brief introduction. The Azure Sky Cultivation Realm is one of the more powerful realms near the Ruins of Return. It is vast in area and has countless cultivation sects of all sizes."

"What you are about to participate in is the Crimson Trial."

"What, the Crimson Trial?"

A gasp rippled through the crowd; they were clearly startled by the name.

The school instructor named Zheng Lei laughed and shouted, "What are you afraid of? Does the Immortal Alliance think you'll go and die?"

"The so-called Crimson Trial is nothing more than a trial jointly organized by the Azure Sky Cultivation World to help low-level cultivators advance. It's nothing special."

About ten minutes later, with the explanation from the instructor surnamed Zheng, everyone finally understood the mission they were about to face.

Unlike Guixu, the Qingqiong cultivation world, despite countless years of development, remains stagnant in an agricultural era.

Simply put, it's classical cultivation of immortality!

Here, without the aid of technology, their methods of acquiring rare and precious materials, refining elixirs, and cultivating spiritual herbs are all very primitive and in a state of ignorance.

Therefore, the Foundation Establishment Pill, which is not particularly precious to Guixu, is extremely rare in the Qingqiong Immortal Cultivation World!

The reason is simple: the raw materials for refining Foundation Building Pills must grow in extremely harsh environments.

You can think of this environment as a small instance or a secret realm.

Such secret realms are extremely rare. In the Azure Sky Cultivation World, apart from the top-tier forces, other sects and families usually need hundreds of members to be qualified to share such a small instance.

Whenever the medicinal herbs ripened, disciples at the Qi Refining stage were dispatched to pick them.

As you can imagine, obtaining something so precious has nothing to do with being peaceful and harmonious. In this small instance, the most basic logic and rule of the cultivation world is followed—survival of the fittest!

Let alone cultivators from rival sects, even those from close sects or even disciples from the same sect might turn against each other in the dungeon in order to obtain more spiritual herbs and exchange them for more contribution points.

Therefore, of the cultivators who enter each time, only one in ten emerges, which is why the term "Bloody Trial" came about.

"Long ago, the Immortal Alliance combined quantum technology with the laws of space, thus breaking the constraints of the spatial barrier."

"However, during Lin Tianzun's time, he simply couldn't be bothered with these backward cultivation circles."

"But things are different now. They are taking advantage of Guixu's weakness to invade this place. Under the organization of the Immortal Alliance, Guixu will naturally launch a fierce counterattack."

"For example, this trial has already pre-anchored the passage to the Azure Sky Immortal Cultivation World. The multi-dimensional barrier-breaking spirit array can accurately teleport you into the instance."

"Instructor!"

Just as Zheng Lei finished speaking, someone raised a hand and asked a question: "So, after we complete the mission, how do we return to the Ruins of Return?"

"Three days!" The instructor smiled slightly and made a gesture: "Don't ask me about the specific details. I'm just a rough man and don't know the specific technical principles. In short, if you haven't perished in three days, you will be automatically teleported back here by a mysterious force."

"Don't worry, you are not the first batch of college students to participate in the experiment. Although the interface you go to is different each time, the technical principles are similar. And the technology is now very mature, with an error rate of less than one in 100,000."

"Of course, if something really goes wrong, you'll just have to pray for the best."

A burst of laughter reached my ears.

Clearly, none of the students believed their luck could be that bad.

"Instructor, what is the purpose of our trip? Could it be that we're here to collect spiritual herbs for refining Foundation Establishment Pills?"

"Of course not." Zheng Lei shook his head and sighed, "In our Guixu, the Foundation Establishment Pill is nothing special."

"The raw materials needed can all be obtained through vertical farming, using controlled nuclear fusion for energy, and AI for precise control to carry out large-scale production. Why would you need to take such risks?"

"Your mission is not to seize resources, but to sabotage; in simpler terms, to prevent the other side from bringing the raw materials out of the secret realm."

"Furthermore, you must kill as many disciples from those hundred or so sects who are participating in the trial as possible. Don't underestimate them just because they are currently only low-level cultivators. Once they grow up, they may become a problem for Guixu."

"After all, no one knows if there will be geniuses among them, or future chosen ones with ridiculously good luck who will grow up to become cultivators in the Integration or even Mahayana stages."

"So every time you kill one more person, you are contributing to the Void and reducing a lot of trouble in the future."

"As the saying goes, prevention is better than cure..."
