If Heaven hadn't given birth to me, I would be arrogant.

How high must the vision of a Great Luo Golden Immortal be? How could he possibly be interested in a cultivation technique from the mortal realm? Zong Ze clearly remembered the disdain in Xiao Hei's eyes when he gave him "Hundred Battles to Form an Army," a technique that was definitely top-tier in the Holy Word Continent!

But today, Xiao Hei is so enthusiastic about "Slaughtering the World" that he even had the idea of ​​borrowing it to read. Doesn't that mean "Slaughtering the World" is something special?

"What, Little Black! You also think this 'Slaughtering the World' is amazing?" Zong Ze's tone was somewhat sarcastic. "How could this trashy mortal cultivation technique possibly catch the eye of a Grand Luo Golden Immortal like you, a level two demon beast?"

"Mortal my ass!" Xiao Hei's tone was completely different from his usual playful and angry tone; instead, it was very serious: "I suspect that this cultivation technique is not a mortal technique at all, but a top-level technique of the Witch Clan. I just don't know how it came to this world and was obtained by your grandfather!"

"The top-tier cultivation technique of the Witch Clan?" Zong Ze and Xiao Hei communicated through mental energy, which required virtually no time. After this exchange, Zong Xiaozhang was still gathering his power: "Could you be referring to the legendary cultivation technique of the Twelve Witch Ancestors?"

"No!" Xiao Hei shook his head: "The Twelve Witch Ancestors are very powerful, but there is actually an even more powerful being above them. Although he was born later than the Twelve Witch Ancestors, his strength far surpasses that of the Twelve Witch Ancestors!"

"What?" Zong Ze was shocked. He had read the "Classic of Mountains and Seas" in his spare time back then. He knew that the Twelve Ancestors of the Witch Clan were already the pinnacle of the Witch Clan, after all, they were transformed from Pangu! Who would have thought that Xiao Hei would say that there were beings in the Witch Clan even more powerful than the Twelve Ancestors of the Witch Clan!

“Yes!” Xiao Hei sighed softly, “This person is Chi You. Although he was born later than the Twelve Witch Ancestors, he relied on killing to dominate the world. Even in the Immortal Realm, Chi You is a sect leader-level existence, terrifying beyond measure!”

"A lifetime of slaughter?" Zong Ze exclaimed in surprise, "You don't mean to say that my grandfather's 'Slaughtering the World' is the cultivation technique practiced by Chi You, do you?"

"Dream on!" Xiao Hei glared at Zong Ze: "If your grandfather had been practicing Chi You's techniques, he would have exploded and died long ago. I suspect that the 'Slaughtering the World' technique that your grandfather is practicing is very likely a technique created by the cult leader Chi You when he was in the mortal realm!"

"What do you mean?" Zongze asked!

"Because just as your grandfather was gathering his energy, I sensed a trace of the aura of the Chi You Cult Master!" Xiao Hei's tone was tinged with fear!

"Okay!" Seeing that his grandfather seemed to be about to finish gathering his energy, Zong Ze agreed to Xiao Hei without hesitation: "When my father starts teaching me 'Slaughtering the World,' I'll show it to you as soon as possible!"

At this moment, Zong Xiaozhang had finished gathering his energy. To outsiders, Zong Xiaozhang appeared to have grown at least fifty centimeters taller, and the battle blade in his hand emitted a brilliant golden light that was so dazzling that people couldn't even open their eyes!

"Hey ha!" Zong roared arrogantly, slashing his battle sword at the city wall with all his might.

A loud clang of metal clashing rang out, making Zong Ze's eardrums ache. The sound lingered, echoing and reverberating for a long time.

A moment later, Zong Xiaozhang retreated to his original position. Zong Ze could see that his grandfather had used all his strength in that strike. At this moment, Zong Xiaozhang seemed to have lost all his strength and could not even stand steadily!

"How...how is it possible?"

Although he was completely exhausted, Zong Xiaozhang's face was filled with shock!

Originally, after several court debates, Zong Xiaozhang discovered that his grandson was too clever. The moment he was summoned to test the city wall, Zong Xiaozhang guessed that Zong Ze's burning of the city wall for ten days was probably a way to reinforce it!

Previously, Zong Ze had no cultivation ability and was ridiculed as an idiot by everyone. Therefore, Zong Xiaozhang strongly supported Zong Ze in using his wisdom. In Zong Xiaozhang's view, although his grandson could not cultivate, it would be good if he could become a being like the Cloud Soaring Saint!

However, Zong Ze is now able to cultivate, and his cultivation talent is unparalleled. Zong Xiaozhang wanted to take this opportunity to warn Zong Ze that even the greatest wisdom cannot overcome superior strength.

Therefore, Zong Xiaozhang exhausted all his strength to unleash this strike. In his view, as long as he could make his grandson understand the importance of strength, it would be worth it even if he collapsed a city wall due to exhaustion!

However, Zong Xiaozhang hadn't expected that his confident strike wouldn't cause any damage to the city wall. The moment his sword touched the wall, he knew that not only had his attack failed, but the wall's sheer strength had also caused him minor internal injuries from the shockwave!

Zong's initial boast that it would take continuous attacks to penetrate the city wall was actually a humble statement. In his own view, even if he couldn't break down a section of the city wall with a single all-out attack, he could at least make a large hole!

As a result, the city wall was completely unharmed, with only a faint white mark indicating the attack it had suffered. On the contrary, it was he, a top expert of the Holy Word Continent and a powerful martial god, who suffered a backlash. How could this not shock Zong Xiaozhang!

"Xiaoze!" After catching his breath for a while, Zong arrogantly asked, "What exactly happened to this city wall? It was clearly built of mud, so why did it turn into this after you burned it? When I slashed at it with my sword, it felt like I wasn't slashing at mud, but at an iron mountain!"

"Haha, Grandpa!" Seeing that his idea had actually succeeded, Zong Ze couldn't help but laugh: "What iron mountain? This is clearly a steel wall! Hahahaha!"

"Steel wall?" Zong asked, puzzled. "What do you mean?"

"Uh... Grandpa, let me explain slowly!" Zong Ze knew that he had let something slip in his moment of pride, but since his grandfather had asked, he had no choice but to try to make up a lie to explain!

“My master once told me!” Zong Ze said slowly, “After iron powder is forged at very high temperatures, it will transform into a very, very hard substance. My master called this substance steel! He said that steel is extremely hard, and ordinary ironware simply cannot compare!”

Seeing Zong Ze's furrowed brow as he fabricated a lie, Xiao Hei beside him grinned wickedly: "Keep fabricating... I'll teach you to show off with all this high-tech stuff from Earth all the time. Now look what you've done, keep fabricating... keep going..."

Xiao Hei was naturally deaf to Zong Xiaozhang's words. After listening to Zong Ze's explanation, he hurriedly asked a question that made Zong Ze even more worried: "So, according to what you said, can we use your method to burn all the city walls of our entire empire into your kind of... uh... yes, steel walls?"
