With a whoosh, a sea of fire materialized around Ling Feng’s body, the scorching aura of the Origin Flame instantly filled the entire practice field, and above the field, a solidified Chaos Beast of Fire Origin sat cross-legged upon it.

Ling Feng looked at the Demon King indifferently; he was indeed confident in the Laws of Fire. From the beginning, Ling Feng first came into contact with the Power of Fire, whether it was the Hell Black Flame or now the Origin Flame.

"Ling Feng, are you ready?" the Demon King said calmly.

Ling Feng nodded, indicating he was all prepared.

Suddenly, the Demon King glared, gripping that Flame Spear, gave a low growl, and then flung it toward Ling Feng.

The Flame Spear charged directly toward Ling Feng, a glimmer flashed in Ling Feng’s eyes: "Good coming!"

Saying so, his hands clapped, the Chaos Beast sitting atop the sea of fire roared as it charged toward the Flame Spear.

One was Origin Power, and the other was ordinary Power of Fire. Ling Feng knew clearly which was superior and which was inferior.

But what shocked Ling Feng happened once more; the Flame Spear actually pierced through the Chaos Beast’s body, blasting it apart, crazily charging at Ling Feng.

"Not good!" Ling Feng was startled, quickly erecting a thick fire wall in front of him, yet the Flame Spear still penetrated the fire wall, heavily striking Ling Feng’s chest.

Ling Feng spat a mouthful of fresh blood, luckily the fire wall previously blocked the Flame Spear’s offensive, plus Ling Feng’s body was incredibly tough, only then withstood the attack of the Flame Spear.

However, this strike truly left Ling Feng shocked. His body was comparable to a top Divine Artifact; even without a fire wall for defense, ordinarily the Power of Fire shouldn’t harm him at all, but...

Ling Feng half-kneeled on the ground, unable to fathom why this was happening!

"Ling Feng, do you still not understand?" At this time, the Demon King’s voice resounded in his ears: "If you haven’t seen through it, then it means you’re far from enough!"

Cold sweat poured down Ling Feng’s forehead; only now did he realize he might not be as strong as he imagined.

"It’s control!" Ling Feng slowly said at this moment: "Whether it was the prior Spatial Barrier or the later Flame Spear, Father-in-law, your control over the Energy Laws has reached a peak state!"

"Though the Flame Spear’s Power of Fire was ordinary fire power, you focused all its strength into the attack without leaking a bit! In contrast, my strength is dissipated rather than concentrated despite being Origin Power, which led to my failure, isn’t that so?"

The Demon King showed a "worthy of teaching" expression: "Correct, apparently you’re not hopelessly stupid! Since you can see through the secret here, it shows you’ve realized your shortcomings!"

"Indeed, what you’re lacking is control—control over self, control over laws, control over all things!" the Demon King said indifferently: "I also admit, your body is a treasure mountain right now; for ordinary enemies, you just need to crush them with immense power. But Ling Feng, don’t forget, the foes you encounter later won’t be those in the Azure Sky Realm, but those in the Half-step Immortal Realm or even Immortal Realm!"

"Your previous techniques against opponents might work for lower-level cultivators but have minimal effect on those whose realm has reached a certain extent!" the Demon King said: "I also know you’re worried about the Mad Doctor, but with your current strength, you’re definitely not the Mad Doctor’s match!"

Ling Feng gritted his teeth: "But the Mad Doctor is only half-step Immortal, and his main body Tooth of Greed was severely injured, I still have the chance to defeat him!"

The Demon King said: "But do you know how long the Mad Doctor has lived? How many clones he once had? How many experiences he’s gone through? How many years he’s immersed himself in the study of laws?"

Ling Feng was silent; he wasn’t particularly clear about any of this. Hearing the Demon King say this, he realized he had never truly understood his enemy, nor did he know his real strength.

"Know yourself and know your enemy to win a hundred battles; you know nothing about the Mad Doctor, yet dream of defeating him?" the Demon King laughed coldly: "And you now know, the Mad Doctor’s main body is the Tooth of Greed. Such a top Chaos Supreme Treasure may be difficult to repair, but likewise, trying to destroy it is nearly impossible!"

"Then what should I do? Am I to watch him devour my planet, harm my relatives?" Ling Feng shouted hoarsely: "I’ve fought so long, been through countless life-and-death moments, what is all this for, if not for my homeland, my loved ones? You want me to watch them die, how is that different from killing me!"

The Demon King sneered: "Then you want to hit a rock with an egg? Ling Feng, you’re far from enough; you don’t know yet how many terrifying things there are in this world, Chaos Supreme Treasure is but one among them!"

"You’ve lost, better sober up here honestly!" the Demon King said indifferently: "Whenever you’re sober, come to see me; if you remain blind to reality, I don’t mind imprisoning you."

Finishing, the Demon King turned to leave, leaving behind a shattered Ling Feng standing dazedly in the center of the practice field.

Ling Feng’s ears kept echoing the Demon King’s words, words like a curse making Ling Feng’s mind restless!

Thinking his current strength was sufficient, but unexpectedly turned around and was totally crushed by the Demon King, was he really lacking so much?

Ling Feng was confused, his eyes filled with perplexity and bewilderment, he even doubted if everything he did was worth it, if everything he did had any meaning.

Watching the dazed figure standing in the practice field, a woman slightly sighed and came to the Demon King’s side: "Brother King, don’t you think this is somewhat excessive? Ling Feng is still quite excellent, you might easily crush him completely like this!"

The Demon King sneered: "Rather than let the Mad Doctor kill him, I’d better reveal this reality to him; if he truly can’t withstand it, then perhaps we’re wrong about choosing him!"

The Witch looked at the Demon King: "Brother King, I didn’t expect you to have such high expectations for Ling Feng, if I’m not mistaken, you’re planning to personally seek out the Mad Doctor, aren’t you?"

The Demon King’s body shivered, then coldly said: "Why should I seek out that madman, boring!"
