Here's the translation of the passage you provided:
At this moment, Qin Hai also took out a sound transmission talisman from his chest and sent the news of this place to the other members of the Chongwu Guard.
"The other Chongwu Guard members will be here soon. I'm too tired and need to rest for a while, so I'll leave the guarding to you."
After saying this, Qin Hai closed his eyes.
Fang Yuan sighed. Having to guard... he was also worn out and barely holding up...
But there was no choice. He braced himself and stayed on guard. With the crocodile demon's dismembered corpse lying nearby, no demon would dare to approach, surely.
Fang Yuan's assumption was completely correct. After a while, everything remained peaceful, with no events occurring.
Demons are capable of thinking, and they had long since avoided this area. Any demon that glanced over was simply showing disregard for its own life.
Fang Yuan relaxed slightly and refocused on the Book of Virtue. The accumulated virtue points had actually reached an astonishing 16,000...
Despite battling tirelessly through the demon tide, the virtue points from that were only half of what he had gained from the crocodile demon, but it was still considerable.
After all, Fang Yuan's account had previously only held a bit over 1,000...
Now, with the demon tide and the wealth from the crocodile demon combined, Fang Yuan felt as though he had suddenly become a nouveau riche.
This journey to the Henglin Mountains had made Fang Yuan even more certain of one thing: strength is the ultimate truth in this world.
With that in mind, his next steps were clear: to firmly grasp the truth in his hands, so that he could better influence others with virtue.
Since there was nothing else to do for now, he might as well level up and boost his health at the same time.
By the way, he still didn't know how to cultivate the Four Realms.
Although the Book of Virtue could give him stat points, Fang Yuan still needed to understand the specific cultivation principles or at least have them recorded in the Book of Virtue.
He turned to Qin Hai, hoping the elder could guide him.
However, the next moment, Fang Yuan frowned.
He realized that at some point, Qin Hai had already lowered his aged head.
This old man had used some secret technique to fight against the crocodile demon, completely overexerting his potential. Was he finally out of energy?
Fang Yuan sighed. Qin Hai could truly be called a good person.
After all, he had sacrificed his life to prevent the demon tide from destroying Songyun County.
What confused Fang Yuan, however, was the Chongwu Hou. Why, instead of coming personally, did he choose to send his Yin spirit from miles away to strike the crocodile demon, leading to the death of one of his generals?
Had something been holding him back?
"Rest in peace, Qin Hai..." Fang Yuan murmured softly. "In your next life, may you cross over to another world and live a life of ease as a gatekeeper."
"Who are you telling to rest in peace?" Qin Hai's annoyed voice suddenly sounded as he lifted his head and looked at Fang Yuan with eyes almost rolled back into his head.
"??! You're not dead?" Fang Yuan felt embarrassed. What a waste of his emotions.
"I'm just tired, taking a rest. Death won't come so easily," Qin Hai shook his head. "It's just that the side effects of that secret technique have destroyed all the channels I had opened. I can no longer be a warrior..."
Qin Hai's voice was filled with regret.
Sensing the mood was getting heavy, Fang Yuan tried to comfort him, "Actually, this might be better. You can now enjoy your later years in peace."
Fang Yuan realized he was good at making sharp remarks when arguing, but when it came to comforting others... he wasn't so good at it. He came off rather awkward.
Qin Hai, however, gazed at the sky and sighed, "Enjoy my later years? I'm only a little over a hundred, this is the time to keep fighting!"
Fang Yuan had no words in response. After all, in this era, that didn't seem like such an unusual statement.
"Stop thinking about such sad things," Fang Yuan said. "It's a good thing you're still alive. Why don't you teach me how to cultivate the Fourth Realm?"
It would also change the subject and give Qin Hai something else to focus on, taking his mind off his melancholy.
So you want me alive just to teach you? Qin Hai glared at Fang Yuan but still began to speak:
"There are three hundred and sixty-two channels in the human body, and only through these channels can we absorb the spiritual energy of heaven and earth."
"So, what we need to do is use our true essence to open each channel and construct a spiritual conduit between them, allowing the body to communicate with heaven and earth."
"The Fourth Realm is called the Opening Channels Realm—the final step before absorbing the spiritual energy of heaven and earth."
"I see. Sounds simple enough..." Fang Yuan, understanding the principles, was about to command the Book of Virtue to start when he heard Qin Hai continue:
"Of course, if you have an Opening Channels Technique to help, the process will be much faster, and it will even give birth to a divine power."
Please don't speak while breathing heavily...
Fang Yuan nodded in response, "Then when I get back, I want the best Opening Channels Technique from the Jianghai Palace."
Fang Yuan felt confident in making that request, given his achievements in the Henglin Mountains.
"Alright," Qin Hai agreed without hesitation, clearly ready to assist.
At that moment, several figures appeared in the distance, rushing towards them.
Each was dressed in silver flying fish attire, with the Chongwu Guard insignia on their heads, except for one individual—an undercover spy, Yan Nan, the Commandant of the Zhenfu Division.
When the Chongwu Guard arrived and saw the gruesome crocodile demon corpse, they were all stunned.
A Fifth Realm Demon Lord, the tyrant of the Henglin Mountains—was really dead like this?!
"Qin Lao, you're too strong!" Yan Nan stared at Qin Hai in shock, as did the other members of the Chongwu Guard.
To defeat a Fifth Realm with a peak Fourth Realm—this was an incredible achievement!
Every martial artist knew that the gap between those two realms was like the difference between heaven and earth!
"It wasn't me," Qin Hai shook his head and pointed at Fang Yuan, dropping an even more shocking statement. "It was this young genius from the academy."
Upon hearing this, everyone froze in place, eyes wide open, as if they had turned to stone.
What did I just hear?
A mere student... killed a Fifth Realm Demon Lord?!
