Those who were named by Lin Yu were asked to leave overnight without alerting anyone.
By the time the hazy rays of sunlight pierced the border region, their berths were already empty.
The investigation into internal spies can take several days.
Later, Lin Yu simply gave Chu Zhen one of his golden rules and let him test it himself.
The main problem was that the job was too boring. Every day, it was just about gathering batches of people in the square, scanning one batch and then another batch would come, it was endless. Lin Yu didn't have the time to be in charge of the testing, so he simply researched a special testing method and gave it to Chu Zhen.
When he had some free time, Lin Yu would often wander around the fortress.
On the training ground, the soldiers were sweating profusely as they drilled, their battle cries deafening, and it looked quite impressive.
However, Lin Yu observed that these people possessed immense power of rules but had no idea how to use it, treating the AK like Fire Stick and wasting a valuable resource.
Su Xiaoxiao had somehow gotten closer, followed his gaze for a while, and sighed, "With this level of skill, if the supernatural attacks again, the casualties will probably be heavy."
She pursed her lips. "G-day is so strange. If we had more time, we might have been able to figure out a more advanced cultivation system. Right now, it's just so-so. Those with good talent can still get a grasp of the basics, but those with poor talent will only be half-baked no matter how hard they try."
Lin Yu sensed the hidden meaning in Su Xiaoxiao's words and glanced at her silently.
How could he not see that the system these soldiers practiced was a mixture of many different powers— Martial Dao, cultivation, immortality cultivation... they had taken anything usable and cobbled it together from various sources.
But precisely because of this complexity, it requires a great deal of talent to achieve mastery.
"Sigh~" Su Xiaoxiao glanced at Lin Yu secretly, and seeing that he didn't react, she deliberately sighed loudly.
"Alright, alright, it's just a lack of a cultivation system. Look at you with that gloomy face. If I don't help you, are you going to keep sighing and complaining by my side?" Lin Yu shook his head and chuckled helplessly.
After watching for a while, he figured out a bit of the trick. In fact, even without him, the official authorities of this world would have developed a new system, but the time span might have been quite long, long enough for many people to die.
Since we're already here, let's do a good deed.
"So you have a solution?" Su Xiaoxiao's previously worried expression instantly turned into a smile.
"There is a solution, but ultimately it depends on you." Lin Yu nodded.
Although as an avatar, he did not inherit the original's Heaven-Defying Comprehension, he was still an avatar of Heavenly Immortal (Daluo Heavenly Immortal), so he still had that much insight.
The next day, he had Su Xiaoxiao gather all the soldiers of the fortress in the square. A dark mass of people stood there, staring at him with confusion.
"You must also be practicing the cultivation system provided by the state." Lin Yu stood on high ground, his voice not loud, but it clearly carried throughout the entire area.
"Today I'm going to teach you something new. This system is something I've developed by combining your own cultivation systems with elements you don't know."
"It's not exactly new. Your world actually already had a rudimentary form, but you were just feeling your way across the river, relying solely on a few tattered books to figure things out, so naturally you're far from perfect."
The soldiers below were all stunned, completely bewildered, not knowing what Mr. Lin was talking about.
However, a few clever people understood the hidden meaning in Lin Yu's words.
Chu Zhen was so excited that his face was flushed, and he quickly had someone record a video.
Lin Yu didn't explain further. He raised his hand and made a sweeping motion, and a golden rule appeared in the sky above the plaza, condensing into a mysterious pattern.
"The Tao that can be told, the name that can be named..."
That's right, Lin Yu started preaching directly. This world also has those classic texts, and some experts are studying them, but the progress is a bit slow. Lin Yu's preaching at most accelerated the birth of this system.
In the days that followed, Lin Yu taught them this new knowledge little by little through sermons.
It's not that difficult.
It's simply about telling them how the power of rules should flow with their blood and qi, how it should connect with their breathing and thoughts, and how it should circulate within their bodies.
Ultimately, it's about going with the flow. Rules are part of this world, and you are part of this world. To utilize them, you must understand how this world operates...
After the sermon, the geniuses sat motionless in the square for a long time, while the foolish ones, if they went back and pondered it more, would understand what Lin Yu had said that day.
Chu Zhen was the first to come to his senses during the sermon.
No one knew when, but the old general was already listening with tears streaming down his face.
He approached Lin Yu, straightened his tattered armor, and bent his knees as if to kneel before Lin Yu.
"Mr. Lin, your kindness is immense! On behalf of millions of compatriots on Blue Star, I express my deepest gratitude!"
Lin Yu reacted quickly and caught him.
"General Chu, what are you doing? I'm just telling you about the paths of those who came before us. Besides, how much of it you can absorb is up to you." Lin Yu said, both amused and exasperated.
Chu Zhen stubbornly refused to rise, his voice choked with emotion. "This lecture by the Master surpasses decades, even centuries, of our arduous research!"
Having failed to kneel, he seemed to remember something and cautiously asked, "Mr. Lin, if I may be so bold, could you perhaps record today's sermon... and send it back to Blue Star?"
"On Blue Star, there are countless official researchers. If they could receive your true teachings, our confidence in fighting the supernatural would be greatly enhanced."
Lin Yu waved his hand. "Pass it on, pass it on however you like."
With Lin Yu's consent, Chu Zhen thanked him profusely and went to make arrangements for the funeral.
Seeing Chu Zhen's face flushed with excitement, Lin Yu was afraid something might happen to him.
No sooner had Chu Zhen left than Su Xiaoxiao came up to him.
"Brother Lin~" she blinked her eyes, her smile incredibly ingratiating.
"Could you give me some extra help with your sermons too?"
Lin Yu glanced at her. "Aren't you the group owner? Why are you short of something like this?"
"Oh dear, even the group admin needs to improve! Besides, only when I become stronger can I better protect this world, right?" Su Xiaoxiao persisted.
"Come on, do you? Do you think I don't know what you're up to? You just want to get something for nothing." Lin Yu said with a look of disgust.
"What do you mean by 'getting something for nothing'? This is an investment! Don't you understand what an investment is?!"
Su Xiaoxiao, hands on her hips, declared, "If I ever become powerful, you'll be the first one I protect!"
Lin Yu was too lazy to argue with her and turned to leave.
Su Xiaoxiao stomped her feet behind her, shouting, "Hey! Don't go! Brother Lin~ Brother Lin~"
