"Killing can provide spiritual nourishment?" Li Yuan was first stunned, suspecting he had read it wrong.
Without hesitation, Li Yuan once again performed the Divine Palace Inquiry, and the display was still correct.
Alien Race! These two words flashed through Li Yuan's mind instantly.
Li Yuan had thought about this issue, that only by killing members of the Alien Race could one obtain spiritual nourishment.
Then, could he use Divine Palace Inquiry to identify members of the Alien Race lurking inside civilization?
Li Yuan had only heard of spies from the Alien Race.
Since his spiritual power broke through level 20, the burden of performing Divine Palace Inquiry had lessened a lot, and he had formed the habit of using it on any significant individuals he met.
It was a pity that he had never encountered an Alien Race spy all this while.
Once his spiritual power broke through level 30, performing Divine Palace Inquiry hundreds of times a day was not much of an issue, so he became even more accustomed to it.
right after he returned from the Mingxu Star Realm and hadn't completely left the war base, he encountered one!
But looking at the man who jumped down from the flying vehicle, his attire, appearance, etc., there was no difference between him and the group of people around.
"Is he really an Alien Race spy?" A hint of doubt crossed Li Yuan's mind, as he could not tell from the appearance alone.
The most crucial point was that Divine Palace Inquiry had always followed the rule that "killing the Alien Race could obtain spiritual nourishment"... but it was not a hundred percent confirmation.
"What's wrong?" Li Yang, who was walking ahead, noticed Li Yuan's abnormality.
"Junior Brother, whom are you looking at?" Shi Xiao also sensed something.
"No." Li Yuan shook his head indifferently and looked into the distance, "I just feel that the man in the leather jacket has a strange spiritual aura... it makes me feel uncomfortable."
"Strange?" Shi Xiao was puzzled.
"Uncomfortable?" Li Yang was shocked. He knew that Li Yuan's spiritual power was most likely at the Flying Heaven Level, and his perception ability was terrifying.
The things that Flying Heaven Level spiritual power could perceive were not to be understood by common sense.
"How uncomfortable?" Li Yang asked.
"Teacher, you should know that I have fought with many strong members of the Tianliang Clan in the Star Realm." Li Yuan spoke readily, "This person... just gives me a feeling of being somewhat similar."
"Tianliang Clan?" A hint of murderous intent flitted across Li Yang's eyes, as he had a deep understanding of this Alien Civilization.
"Teacher, it's just a feeling of discomfort, I can't confirm anything," Li Yuan shook his head, "You should know, my perception is very acute."
This was the excuse Li Yuan had thought out.
First, he couldn't expose the Mind Spirit Divine Palace, and second, Divine Palace Inquiry alone couldn't confirm the person's identity as a spy, let alone serve as evidence.
What reason then? Intuition!
As a Martial Path genius with Flying Heaven Level spiritual power, Li Yuan's intuition was evidence in itself.
"Okay, I understand," Li Yang nodded gravely, "I will have him closely watched right away, wait for me."
Saying this, Li Yang had already beckoned over and promptly summoned several Martial Artist officers.
Li Yang quickly explained the reason.
Naturally, Li Yang used other reasons, as he didn't want to involve Li Yuan.
"Understood, President Li."
This Martial Artist officer wearing the rank of 'Major' said solemnly, "I have just reviewed the data; that person is a warriro from the Starry Sky Martial Hall, who had recently applied to enter the Mingxu Star Realm... We will closely monitor him."
The reason given by Li Yang was far-fetched, considering Li Yang didn't even recognize the person.
But as a Top Grade Origin Martial Artist and a Vice President of Kunlun Martial University.
When Li Yang suspected a First Rank Martial Artist was a spy of the Alien Race.
That was the greatest reason and evidence.
"What about the others? Have a look." Li Yuan was nonchalant, not interrupting the conversation, but continuously performing Divine Palace Inquiry, checking the other people he saw.
Everyone appeared normal to his eye, only that man in the leather jacket showed an anomaly.
Soon, the group of Martial Artist officers scattered as if nothing had happened.
"Li Yuan, let's go," Li Yang whispered, "The military will start close surveillance on him from today, examining his many connections, past experiences, previous network communications, etc... If he is indeed an Alien Race spy, he will sooner or later show some telltale signs, and we may even be able to root out a whole bunch of people by following the trail."
"Understood." Li Yuan nodded slightly.
Encountering such an Alien Race spy, it was not best to apprehend them immediately.
Instead, it was better to clarify the entire spy network behind him and then aim to catch them all at once.
As for proactively checking more people?
"Not to mention that I can't expose the Mind Spirit Divine Palace."
"Even if I did and the alliance's high ranks believed that checking hundreds a day wouldn't affect me, but what about thousands? Tens of thousands?" Li Yuan secretly sighed, "If I were to inspect day and night, I could perhaps check up to a few million people in a year."
How many people are in the whole Seven Star Alliance? Almost two hundred billion!!
Li Yuan couldn't complete the check in ten lifetimes.
Furthermore, as far as Li Yuan knew, the vast majority of spies were 'traitors' who sold out their civilization for their own benefit—traitors that Divine Palace Inquiry could not detect.
The actual members of the Alien Race who had infiltrated and were living within human civilization were still very few.
"Better to focus on cultivation."
"If I truly want to perform comprehensive screening, wait until my spiritual power surpasses the Flying Heaven Level, when the efficiency would be at least a hundred times higher," Li Yuan thought to himself. "From now on, whoever I meet, I'll just take a casual look."
The small number of Alien Race spies infiltrating the realm couldn't affect the entire civilization.
But if a being surpassing the Flying Heaven Level were to emerge, it would be of greater importance to the entire Seven Star human civilization.

"To help the entire civilization, I must first protect myself," Li Yuan mused, "With my reputation growing bigger, who knows, I might even provoke assassination attempts by the Alien Race."
"From now on, I will perform Divine Palace Inquiry on every person who gets close to me, to prevent any unforeseen incidents," Li Yuan was very cautious.
