”How... How is that possible? ”

Although he lacked any strength, Ye Xiaozhang's face was full of shock!

Originally, after a few court debates, Ye Xiaozhang had realized that his grandson was too smart. The moment he called him over to experiment on the city walls, Ye Xiaozhang had already guessed that Ye Fei's Ten Days of Burning Fire was probably a way to strengthen the city wall!

In the past, Ye Fei did not have the ability to cultivate, so he was mocked as an idiot by the crowd. Therefore, Ye Xiaozhang strongly approved of Ye Fei using his own wisdom, in Ye Xiaozhang's opinion, although his own grandson couldn't cultivate, but being able to become an existence similar to the Saint Hai Xuan was still very good.

However, Ye Fei could cultivate now, and his talent was also peerless, Ye Xiaozhang wanted to use this opportunity to warn Ye Fei, no matter how strong his intelligence was, it would not be able to match up to his strength.

Therefore, Ye Xiaozhang exhausted all his strength to make this cut. In his opinion, as long as his grandson understood the importance of strength, it would be worth it even if he himself lost all his energy and collapsed a city wall!

But Ye Xiaozhang had never thought that a slash filled with self-confidence would actually not cause the slightest bit of damage to the city walls. The moment the sword in his hand collided with the wall, he knew that not only had his slash failed, it had even caused some light damage to his internal organs from the recoil of the wall!

In the beginning, Ye Xiaozhang said that he would need a continuous attack to break through the city wall, but he was merely being modest. According to him, if he were to use his full power, even if he could not break down one of the walls, he could at least make a big hole!

As a result, nothing happened to the city wall, only a faint white mark showing that it had been attacked before. On the contrary, it was his own, the top expert of Miracle Continent, a person with the strength of the War God who had suffered a backlash.

”Fei!” After resting for a while, Ye Xiaozhang asked: ”What exactly is going on with this city wall? It was obviously made of mud, but why did it become like this after being burned by your fire? When I cut down with my blade, I didn't even feel as if I was chopping at mud, but at the top of an iron mountain! ”

”Haha, Grandfather!” Seeing that his plan had succeeded, Ye Fei naturally couldn't help but laugh. ”What iron mountain? This was clearly a steel wall! ”Hahahaha!”

”Steel wall?” Ye Xiaozhang was confused: ”What do you mean?”

”Ugh …” Grandfather, listen to me explain it to you slowly! ” Ye Fei knew that he had leaked everything he was proud of, but since his grandfather had asked, he could only think of a way to lie and explain it!

”My master told me this before!” Ye Fei said slowly, ”After being calcined at a very high temperature, the iron powder will turn into a very, very hard substance. My master calls this substance steel! He once said that the hardness of steel is extremely high.

Seeing Ye Fei who was lying with a troubled face, Xiao Hei who was at the side laughed sinisterly: ”Fool, continue to make things up …. I told you to get some of the high technology on Earth to show off every now and then. ”I can make it up really hard …”

Of course, Ye Xiaozhang couldn't hear Xiao Hei's words. After hearing Ye Fei's explanation, he hurriedly asked a question that made Ye Fei even more distressed, ”Then according to what you have said, can we use your method to burn down all of the Empire's walls? ”Ugh …” ”Right, steel wall?”
