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

"Can……"

Zhou Ran looked aggrieved and wanted to argue his case. He was a freshman who had just started university, and only three months had passed since he enrolled. The school year was not even over yet, so how could he have had the opportunity to come into contact with talismans and magical artifacts?

Do you think the teacher will teach this required course to me at this time of year, even though it's supposed to be a compulsory course next semester?

However, he had only uttered one word when Zheng Lei cast a spell, and in an instant, Zhou Ran's voice turned into a series of barking dogs, which immediately caused the crowd to burst into laughter.

"This guy is amazing."

"Yeah, they're incredibly stubborn, going against the instructors again and again. They really don't know what death means."

"He's a clown, you should stay away from people like that."

……

Duan Xuan sighed. This time, his friend hadn't actually been spouting nonsense. It was a pity that his first impression was so bad. Sigh, this is just like the story of the boy who cried wolf!

After a slight hesitation, Duan Xuan did not speak up to defend Zhou Ran. It wasn't that he wasn't a good brother, but rather that if he tried to explain, he would expose the origins of the three of them.

Shuiyun Daoyun Academy is the number one cultivation academy on Shuiyun Star. The three of them are in the top class, which can be described as geniuses among geniuses, making them stand out too much among all the junior college students.

Although it didn't seem like a big deal to have it exposed on the surface, for some reason, Duan Xuan felt uneasy and decided to keep it as a trump card.

So he remained silent.

And this is just one of the reasons.

Secondly, he wanted to explain that it would take a lot of time, and with only three days left until the trial, Duan Xuan didn't want to affect everyone's cultivation progress because of his own reasons.

As for the use of ritual implements and talismans, what should be done?

Yes, Lingyun just whispered in my ear that it's not difficult. An ordinary student might need several weeks to master it, but both I and Zhou Ran are Heavenly Spiritual Roots. Although there is still a huge difference in our aptitudes, mastering it in a short time is no problem.

So there's no need to rush this!

This was just a minor incident that quickly passed, and no one took Zhou Ran's words to heart from beginning to end.

After all, what just happened proved how unreliable this kid is. Everyone thought he was just having a personality tantrum and trying to get attention.

Zheng Lei then didn't waste any time and made the most of his time to give a lecture to everyone.

He then took out a similar military backpack, removed the technological equipment inside, and personally demonstrated to the students how to use it and the key points to note.

As expected, the logistical equipment provided by the Immortal Alliance included not only weapons, but also all sorts of practical items.

For example, right now, Zheng Lei is holding something that looks like a contact lens.

It's very thin, and looks almost completely transparent.

"What is this?" a student couldn't help but ask.

Zheng Lei smiled and put it in his glasses, explaining as he did so, "This is a nano-spiritual energy value detector."

"As its name suggests, it has two functions."

"Firstly, it's similar to a miniature radar. When a cultivator approaches, it can issue an early warning. Combined with divine sense, this high-low combination can reduce the probability of being ambushed by 92.1%..."

"Secondly, it can also roughly estimate the combat power of a cultivator through spiritual energy reactions."

"For example, if a mortal has no spiritual energy fluctuations, their combat power is set to 0."

"The combat power of the first level of Qi Refining is about 5. Of course, everyone's situation is different. Some people will have a higher number, and some will have a slightly lower number, but there is a reasonable fluctuation value."

"At the first level of Qi Refining, even the most talented person will find it difficult to exceed 10. Correspondingly, no matter how trashy or outrageous the cultivation technique is, the minimum combat power is usually guaranteed at 3 points."

"As for the specific combat power at each stage, there is a dedicated database in the Nano Spiritual Power Numerical Detector, which you can check and compare yourself."

"By the way, the instrument provided by the Immortal Alliance is only a simplified version of the basic model, which can only measure combat power up to the mid-Foundation Establishment stage at most."

Zheng Lei added a reminder.

Everyone was overjoyed, as this was a wonderful thing, and they all started to test and tinker with it.

Duan Xuan was also very curious and took out the nano-spiritual energy value detector.

This is a thin, very soft lens. When you hold it in your hand and squeeze it, it feels like a water droplet. At first glance, it looks somewhat similar to a regular contact lens, but it is more beautiful and more high-end. And there is only one lens available, so you can choose to wear it in your left or right eye.

As for how to wear it, it's very simple. You just need to hold it with one hand, just like putting in eye drops, and gently squeeze it. This mysterious device will then fall into your eyes very smoothly, without any discomfort throughout the process.

Ding!

A soft sound came from my mind, followed by the sound of the nano-spiritual energy value detector starting up.

System self-check!

Soon, a semi-transparent image appeared in Duan Xuan's left eye, like a huge holographic projection screen, displaying lines of numbers and letters.

"What is this?"

Duan Xuan was very surprised and couldn't help but mutter to himself. Just as he was about to study it in more detail, a silvery laugh came over.

"Host, don't be surprised. This nano-spiritual energy value detector not only serves as a tool for detecting combat power, but also has the effect of radar early warning. At the same time, it also integrates navigation maps, identification and detection of rare and precious materials, real-time communication, and environmental parameter detection, making it a very practical technological treasure and arguably the best aid for cultivators."

"Oh, it has so many uses?"

Duan Xuan couldn't help but show a look of surprise on his face.

However, I still have some doubts. The navigation map, the identification and detection of rare and precious materials, and instant messaging are all easy to understand. But what is this display and detection of environmental parameters?

"This is a very useful function, so please don't underestimate it, host."

Lingyun's melodious voice, as sweet as a nightingale's, reached my ears: "Let me give you an example. You are about to embark on an adventure in the Azure Sky Immortal Cultivation World, and those dungeons and secret realms will certainly be filled with all sorts of dangers. In addition to cultivators and demons, the influence of the environment should not be underestimated."

"For example, you might encounter miasma, poisonous fog, or even traps and swamps. Because it's a different interface, even the most basic gravity environment, oxygen content, and pH value of the water may be quite different from those on Mercury Planet."

"Don't underestimate these things. Although cultivators are very adaptable, they can still have a significant impact, and may even bring about a huge crisis unintentionally."
