Seeing that a single strike had replenished his depleted spiritual energy, and feeling the purest energy filling his body, Young Master Wang couldn't help but groan.

"Although it wasn't the first time, the feeling of getting feedback is truly fascinating..."

Although Wang Zheng successfully took the head, the demon king did not utter a single word of begging for mercy until his death, nor did he reveal any information about the Fragrant Musk King.

Looking at the data panel, the spiritual energy value surged by 150,000, the precise and accurate calculations highlight its meticulousness.

This once again confirms Wang Zheng's previous conjecture: the reward for killing these demon kings is their own spiritual energy limit.

The sudden surge of spiritual energy reminded Wang Zheng that he should quickly gather his spoils and leave.

After all, judging from the behavior of the Illusionary Fox Demon King, there is a high possibility that there is another demon king hiding deep within Kunxu Mountain.

Although he had defeated the Illusionary Fox King, he had overestimated his father's combat power from the very beginning. Now, his father had been hit by the self-destruction of the inner core and was not in good condition, so he dared not be reckless.

Seeing his father still struggling with the gradually weakening spiritual energy waves in mid-air, Wang Zheng thought that even if he had the ability to recover, the enemy was in the dark while he was in the light, so he still had to prioritize stability.

At worst, I can just go around in circles and come back to the beginning once Dad has fully recovered.

With Chi Yun around, going in circles is no problem at all...

Despite the intense fighting since the start, it only took a dozen minutes from the initial treachery to Young Master Wang's sudden outburst, and then to the Illusion Fox King's self-destruction, which left him weakened and decapitated.

The established goal has been achieved, and even though we killed the wrong demon, it doesn't matter anymore.

Although Wang Zheng still felt a little regretful about the self-destructing demon king's inner core, looking at the enormous demon king's corpse in front of him, he couldn't say he hadn't gained anything at all, could he?

Thinking about it this way, our young master Wang felt much better.

Putting aside the fact that the gained spiritual energy and the consumed spiritual energy cancel each other out, since it's only a kill reward, it's still a bit of a loss. But anyway, I guess I'll just add one Golden Sun Fruit fragment to my collection.

However, the materialization progress he had hoped would increase again remained completely unchanged on the data panel, which greatly worried our young master Wang.

He was even wondering if he needed to kill the Demon King alone to continue increasing his progress.

At this moment, Wang Shengrong finally managed to shatter the energy surge caused by the self-destruction. He put away his Dharma form and slowly descended from mid-air, his face pale, clearly shaken by his reckless actions.

Looking at the demon king's corpse engulfed in raging flames, he curled his lip in disgust at his son, then took the initiative to suppress the flames on the demon king's body.

At this time, the demon king was already dead, and his domain had disappeared. The power of the rekindled candle flames was much weaker, and it was soon completely suppressed.

After disposing of the body, Wang Shengrong noticed his son's furrowed brow and asked:

"What's wrong? Is there a problem?"

Without even turning his head, Wang Zheng proactively cast several holy light spells on his father, helping him recover from his injuries.

His scan showed no major problems.

My dad still has a little over 1000 stamina points left.

The power of the opponent's self-destruction, plus the energy tide, only managed to reduce Old Man's "health bar" by less than a third. Looking at this result, Wang Zheng had a direct understanding of the Demon King's attributes and the power of his self-destruction.

Thanks to Wang Zheng's abundant milk supply, Wang Shengrong recovered completely in no time.

Wang Zheng looked at his father, who had regained his energy but was still somewhat tired, and while putting the demon king's corpse on the ground into his storage space, he replied:

"Two problems. First, killing that demon king did not increase my materialization progress."

Although I had made preparations long ago, this meant that I could not complete the transformation of heaven and earth in a short period of time, which also meant that I did not have the ability to decide the outcome of the battle at critical moments.

As you saw in this battle, that Candle Flame Energy Ball was the maximum power I could unleash in my concealed state, but it's clear that it's far from enough to directly kill the Demon King.

"A sneak attack with a deadly strike, a one-hit kill—that's something only you can do."

Upon hearing this, Wang Shengrong nodded.

"It's already quite good. After all, Xiao Zheng, you haven't even transcended the mortal realm yet, and the energy gap is there. As for the progress of visualization, there might be other factors involved. Killing more will eventually increase it!"

Hearing his father's words of comfort, Wang Zheng didn't think much of it and continued:

"The second problem is that there is likely another Fragrant Musk King here, and it has a close relationship with this Colorful Night Fox. We need to leave immediately..."

Wang Zheng was interrupted by Wang Shengrong before he could finish speaking.

"Why retreat? Isn't this perfect? ​​We'll kill them as soon as they arrive. That was my first time fighting a demon king, and I had no experience. This time, I'll make sure we win."

Wang Zheng was speechless.

"You're making such a racket here, like you're tearing the house down. If that demon king is really nearby, how could you not notice him? Without a chance to ambush him, I doubt you'd be able to defeat these demon kings."

Hearing his son's bluntness, Wang Shengrong immediately became displeased.

"How dare you talk like that? Who can't beat whom? Didn't you see I punched her and smashed her to pieces? You must have gotten some incredible luck, now you're all cocky?"

However, despite his stubbornness, Wang Shengrong was still somewhat aware of his own limitations. After all, the original plan of the father and son was to kill their opponent with a single blow, leaving no chance for the opponent to self-destruct their inner core.

His own son lived up to expectations and created an excellent opportunity to attack, but because he himself held him back and overestimated his own abilities, he ended up in a tough battle.

Seeing the disdain in his son's eyes, Wang Shengrong, after much agonizing thought, finally murmured:

"Although I am better at hand-to-hand combat, I am still not quite used to aerial combat. In addition, I haven't developed this superpower to its best state. Can you lend me that bone knife? I think I'll be able to use it more easily next time."

Wang Zheng didn't say anything about this, but after thinking about it carefully, he also felt that it made sense.

Without the sharpness of this Poisonous Bone Blade, even with the enhancement of the Candle Flame, burning the opponent to death wouldn't be a problem. However, it would probably be difficult to cut through the Demon King's defenses so easily and reap the spoils.

So he handed over the bone knife while offering words of comfort:

"Forget it, forget it, it's already pretty good. At least Mom has half of her spiritual fruit. Let's just consider it practice for next time."

But Dad, you need to be careful. This bone knife also contains the neurotoxin of the venomous python king, making it quite tricky to use. Try it first and see if it affects you.

"If that doesn't work, I also have two large hammers and a Miao sword, but the quality is slightly lower. They're just A-grade alloy with some demon king bone added, so they might not be as satisfying as your fists and feet."
