Speaking of the timing of picking leaves under the protection of the ice, Shanhe's face was full of helplessness. It didn't take long to see him pointing to the residual leaves in Jiang Nong's hand and said:

"The remnant leaf you are holding now is the best achievement that the disciple has achieved under the dual protection of ice and internal breath. The results seem to have improved a lot, and they are much bigger than the previous ones. But in my opinion, this is really not progress! Because I have selected more than 30 broken leaves for this experiment, but in the end there are only two or three pieces that can be used. The rest of the leaves are either destroyed or not activated, and the waste is very serious. In the future, Emperor Shenyin will be mass-produced, and if it only relies on this unreliable mode of production, it will definitely not work. ”

After talking about the origin of the second broken leaf, Shanhe clasped his hands in front of his chest, and his brows furrowed slightly, as if he had returned to the state of mind at that time.

After listening to the questions talked about by Shanhe, the excitement on Jiang Nong's face quietly receded.

I saw him holding his chin with one hand, staring at the broken leaf in his hand that had survived, and fell into contemplation with the mountains and rivers. About half a minute later, Fang sighed lightly:

"Alas, you're right, such a precarious success rate is indeed worrying. Sanke, you can think so long-term, especially if you are willing to consider the future production of Emperor Shen Yin, the old man is really very pleased!"

If it is placed on weekdays, the ginger farmers who have already had a great harvest will not have any other extravagant expectations.

But today, seeing that there was a jade box on the table that had not yet been opened, Jiang Nong faintly felt in his heart that there was a surprise waiting for him after this, so he asked with a little apprehension:

"Then, what about later, did you think of another way?"

After listening to Jiang Nong's inquiry, under the gaze of the other party, Shanhe slowly picked up the last jade box on the table. Putting it in his hand and not rushing to open it, he opened his mouth and said:

"Internal breath acts as a buffer and makes the conductivity of heat less conductive. When the ice melts when heated, it also absorbs the heat around it and blocks the heat from spreading. Not to mention 420 degrees, even if it is 430 degrees or 440 degrees, as long as the thickness of the internal breath and ice layer is continuously increased, the broken leaves can be preserved intact. Nowadays, how to successfully activate the void breaker under these two powerful thermal insulation layers has become a problem!"

Speaking of this, he listened to the voice of Shanhe and put forward a term that he had never said:

This sounds a bit contradictory, but I didn't have a better idea at the time, so I wanted to give it a try, maybe there would be some miraculous effects? Just like the traditional Chinese medicine prescriptions that have been handed down since ancient times, in addition to the main and auxiliary medicines used to treat diseases, they also need to be decocted with some medicinal materials that dissolve the toxicity of the drugs. And most of these drugs are contradictory to them, seemingly contradictory but hidden in philosophy. ”

Hearing that Shanhe even moved out of the pharmacology, Jiang Nong couldn't help but nodded. But before he could speak, he listened to Shanhe continue:

"The ice layer and the inner layer are like the main medicine in the prescription, and their role is to protect the broken leaves. However, in order to properly reduce the 'toxicity' of these two protective layers, it may be possible to find some drugs that are compatible with them. With this in mind, the disciple read a lot of ancient pharmacopoeia books, and finally selected eight materials with good thermal conductivity and non-toxic and harmless to the human body as experimental objects. ”

"Whew! For more than ten years, the old man has been searching for a way to protect, but you have to go the other way, and increase heat conduction in addition to protection. Hehe, it's a bit interesting, you are bolder than the old man!" After sighing heartily, I heard Jiang Nong ask urgently:

"What is the end result? Are these eight materials useful?"

After saying this for a long time, Shanhe doesn't plan to sell Guanzi anymore. Seeing that Uncle Shi's expression was so eager, he directly opened the lid of the jade box:

"Shi Bo have ever heard of a material called 'Purple Tear Rock', which is light purple and rocky, and when it is naturally formed, it is the size of a teardrop. As one of the commonly used excipients for refiners, the thermal conductivity of purple tear rock is very prominent, and it is non-toxic and harmless, and will not affect any medicinal properties, which is very suitable for the refining of broken leaves. ”

"Purple Tears Rock?" Jiang Nong nodded and said:

"Well, the old man has heard of this thing. Many of the medicine tripods used by alchemists need to be refined with purple tear rock, which does have this effect. ”

After three days of experiments, compared with the other seven kinds of thermal conductive materials, the disciple finally selected the purple tear rock with the best effect as the main material of the thermal conductive layer. For ease of operation, this time I didn't add a separate layer, but instead crushed the Purple Tear Rock and mixed it with water, and after freezing, it became a hybrid protective layer, which I privately called the 'Purple Ice Layer'. ”

The clear water is colorless, but because of the addition of purple tear rock powder, it turns into purple ice after freezing, so the mountains and rivers are so named.

"Until last night, after more than twenty proportional adjustments, an activated Void Breaking Leaf Fang stood out, which made the disciple very excited! Then, in order to ensure that this method was feasible, the disciple tried twice more according to the same proportion, and the results were the same. As for how big the broken void leaf is that is preserved in the end, hehe, Uncle Shi should see for himself!"

As soon as the words fell, Shanhe turned the last jade box upside down in Jiang Nong's hand.

When the jade box was removed, he saw three broken leaves lying quietly in his hands.

If you look closely, the three leaves are slightly reddish, and the interlaced veins on the surface of the leaves are clearly visible.

Although they have been roasted at high temperatures, they still give people a sense of vitality.

As for their size, they are intact except for some inevitable chips and cracks around the edges of each leaf. If you look at it proportionally, its completeness is definitely more than 95%!

Jiang Nong thought he was well prepared, but when he saw the three almost complete broken leaves, he still couldn't suppress his excitement.

On the slightly old face, there was too much emotion gathered for a while, but it looked a little sluggish. I was stunned in place, and I couldn't say a word after a long time!

Seeing that the master didn't react for a long time, Shanhe was a little anxious, reached out and poked Jiang Nong's forearm, and asked softly:

"Uncle Shi, don't be stunned, quickly check and check to see if there is anything wrong with these leaves!"

Under the reminder of the mountains and rivers, Jiang Nong barely came back to his senses.

His heartbeat accelerated again, so that his eardrums thumped, and after swallowing his saliva fiercely, he raised his arm tremblingly and sent three leaves to his nostrils.
