After listening to the questions of the mountains and rivers, Jiang Nong's emotions gradually calmed down. After pouring a cup of hot tea for the two, he continued his sermon:

"The old man was as puzzled as you at that time, and began to study the next day. In order to find out the cause, I did a lot of experiments, taking into account all the relevant elements such as fire, electricity, electrolyte, temperature, humidity, smoke, etc., and even restored the fire scene to simulate the accident. About a month later, I finally discovered the secret!"

Seeing that Jiang Nong stopped again when he said the key point, Shanhe immediately urged: "What is it? Uncle Shi, don't gasp for breath at the critical moment, okay?"

Hearing this, Jiang Nong's face first crossed a wicked smile, giving people the feeling that he was deliberately selling off.

After an interval of three or five seconds, he moved the small stool under his buttocks forward a few points, lowered his voice and preached to Shanhe:

"What the old man said next is all confidential matters, don't tell others, understand?" After seeing Shanhe nodding in agreement, Jiang Nongfang continued:

"According to the results of the old man's experiment, there is indeed a void-breaking element in the hollow-breaking leaf, but it is not the same as the hollow-breaking element in the hollow-breaking fruit. ”

"What's the difference?"

"The void-breaker hidden in the leaves is more like the void-breaker in a dormant state. It is difficult to detect until it is activated by a specific condition. Even if it is refined, it does not have the effect of enhancing the dantian, and it is far from the normal state of the void-breaking element. ”

"Dormant?" Shanhe scratched his head as if he didn't understand, and said, "Breaking the Sky Element will still sleep?"

"Alas, the old man is just making an analogy, why are you so stupid little baby!" Jiang Nong said angrily:

"To say that it is 'dormant' is not really sleeping, but rather to the lack of a certain conditional transition. It is only under certain conditions that it can be transformed into a true void-breaking element, which is why the old man has not been able to find it for the past ten years. ”

"Oh, so I need to convert......"

"That's right! Only after transforming and activating it can it be compared to the Void Breaking Element in the Void Breaking Fruit. The old man also guessed that the void breaking elements in the Broken Empty Fruit should all come from the branches and leaves, but if they want to converge and transform under natural conditions, the process is not only complicated but also takes a long time, which is why the Broken Empty Fruit has to wait five years to mature. ”

After listening to Jiang Nong's explanation, Shanhe nodded slightly, probably understanding the truth.

But the most important thing about the transformation of the void breaking element was that he had not yet learned, and it didn't take long for him to ask:

"Uncle Shi, what are the conditions for activating the Void Breaking Element in the Void Breaking Leaf? I have gone through all the information you gave me, and I have not found any records. ”

Seeing Shanhe ask about this, Jiang Nong frowned, and sighed lightly:

"Alas! Although the old man has figured out the so-called conditions, he cannot realize them at all! There is no record in the information, so the old man did not write them down for the sake of secrecy. But in fact, the old man told you what the conditions were a few days ago, have you forgotten?"

"Ah, you, did you tell me?," Shanhe said with a confused expression.

"Hehe, just when you and I met for the first time!"

Hearing what Uncle Shi said, Shanhe's thoughts quickly froze on the night of the competition a few days ago. While thinking about it, he guessed:

"Is that the condition...... The question you gave me at the time?"

Seeing that Shanhe had guessed the answer, Jiang Nong nodded slowly:

"That's right, if you want to activate the void breaking element in the leaves, you must first heat the leaves to 420 degrees, and then decompose them with healing techniques, so it is possible to activate it! At that time, it was the first time I met you, and I was not very familiar with you, so I can't tell you the meaning behind this matter, hehe, you won't blame the old man, right?"

When he first participated in the competition, Shanhe really didn't understand why Shi Bo had to force himself to do such a strange question. And now after listening to Jiang Nong's experience, Shanhe can be regarded as understanding the truth and understanding it. If it were him, he would definitely not tell such a confidential thing to a person who met him for the first time, and immediately nodded and replied:

"Uncle Shi is cautious and right, I can understand that. However, Shi Bo discovered this condition as early as 10 years ago, why hasn't he been able to ...... today?

was asked by Shanhe like this, Jiang Nong lowered his head on the spot, and there was a long sigh in his mouth, and it was not difficult to see that he was also helpless about this matter.

Picking up the teacup on the table, I just wanted to take a sip, but I found that the tea in the cup was already cold, so I went back to the house and poured a new pot of tea. After bringing it out, Fang sat down and said:

"Ten years ago, when the old man discovered the activation conditions, he thought that it was hard work, and the emperor god Yin could finally come out! But who knows that the world is unpredictable, and in the next ten years, the development of the emperor god Yin encountered another problem, trapping the old man in the same place. ”

After adding a new cup of tea to Shanhe, I listened to Jiang Nong preach to Shanhe while drinking tea:

"The last time in the Broken Void Valley, when the old man asked you to decompose the Broken Void Leaf, you should have noticed that the Broken Void Leaf is extremely strong in nature, and it is very resistant to heat and corrosion, and ordinary high temperatures can't help it at all. But once the temperature exceeds 400 degrees, the broken leaves quickly collapse like hot ice cubes, and they cannot be retained at all. Over the years, the old man has tried a lot of methods, whether it is the secular world or the cultivation world, but no matter what, as soon as the 400 degrees are crossed, the broken leaves will be melted by the high temperature. Even if there is an occasional trace of crimson ashes, the content is ridiculously low, and it does not meet the old man's expectations......"

For what Jiang Nong said, Shanhe, who had a "heating" experience, is particularly agreeable.

He remembered very well that at that time, in the Broken Void Valley, the Broken Void Leaf in his hand began to fall apart after 400 degrees, and it was indeed difficult to preserve.

"Uncle Shi, according to what you say, haven't you succeeded once in the past ten years?"

"Alas, I'm ashamed to say it, it's true!" Jiang Nong replied with regret in his eyes:

"Truth be told, the best result so far was your attempt in the Void Valley. The remnant leaf you left behind is the biggest success the old man has seen in the past ten years!"

When the temperature of the mountains and rivers rose to 420 degrees in the Broken Sky Valley, the Broken Sky Leaf in his hand "self-immolated" on the spot. In the end, only a red remnant was left less than the size of a tiny fingernail.

For this reason, Shanhe was quite ashamed and felt that he had not completed the exam questions of his uncle.

But now that I heard it, that little residual leaf was actually the best result in ten years, and this news really surprised Shanhe.
