The key to saltpeter ice making is naturally on saltpeter.

In Jiang Chen's memory, Zhongzhou has the use of saltpeter, such as making fireworks, firing jade glaze, etc., which is called flame salt.

"Flame nitrate, I don't have it in the Spirit Garden, but I need this thing for the Peacock Garden to burn the color glaze, and there should be a lot of reserves there, Xiao Li, you take a few people to get some!"

Although Hai Dafu wondered what the relationship between the flame nitrate and the creation of the cold environment was, Jiang Chen, the "future imperial husband" and "son of the immortal family", opened his mouth, of course he obeyed his words and immediately gave orders.

"Yes!

Deacon Xiao Li no longer had the slightest suspicion, glanced at Jiang Chen with reverence, responded loudly, and walked quickly outside.

"Jiang Gongzi, it is estimated that it will take some time to take this flame nitrate, I will wait until I sit next to me, drink a cup of tea, and take my time. ”

Hai Dafu asked Jiang Chen to drink tea with a fat face, but Jiang Chen was naturally disrespectful and smiled.

The two sat under the pavilion not far from the seven-leaf blood orchid, sipping tea, listening to Hai Dafu casually talk about some rumors about the imperial city, and two quarters of an hour passed quickly, and Deacon Xiao Li walked back with a few subordinates and a few wooden barrels full of saltpeter.

"Jiang Gongzi, what should I do next?"

Deacon Xiao Li's eyes were full of respect and fanaticism for Jiang Chen.

"Take a couple of large buckets, fill them with water, and take a larger container and place the buckets in them. ”

Jiang Chen commanded.

"Yes!"

Deacon Xiao Li and the others immediately took action, and after a while, the container was set up in front of Jiang Chen, and inside the container was a large bucket full of water, and then excitedly began to wait for his next move.

"Isn't Jiang Gongzi going to use immortal magic and directly turn water into ice?

"Hmph, Jiang Gongzi's methods, how can you understand them?"

The two servants of the Spirit Garden stood behind Deacon Xiao Li, whispering in a low voice.

"Shut it all up for me, watch it well!"

Deacon Xiao Li let out a low snort, stopped the small noise behind him, and suddenly, a pair of eyes all looked at Jiang Chen.

"Add the nitrate to the container. ”

Jiang Chen methodically guided the next step.

As pieces of saltpeter with a slight vitreous luster were added to the container, Jiang Chen spoke again.

"Fill the container with water as well, making sure it goes over the barrel. ”

The servants meticulously followed Jiang Chen's orders and poured the water into the container, and the sound of rattling was endless.

"Jiang Gongzi, what should I do next?"

Deacon Xiao Li came to Jiang Chen's side and excitedly waited for his "Immortal Magic".

"Just wait a moment. ”

Jiang Chen didn't turn his head, and quietly looked at the "test site" in front of him.

Wait a moment?

Deacon Xiao Li turned his head suspiciously and looked ahead.

"Goo-dong...... Gollum ......"

Suddenly, the sound began to sound in the container.

"What sound?"

A group of people leaned over their heads and looked curiously, and in an instant, their eyes widened.

"This ...... What's going on?"

In front of their eyes, as the saltpeter melted in the water, the container reacted violently, and the water in the central barrel began to solidify gradually, forming transparent crystals.

"Yes...... Ice!"

One of the servants shouted.

"What?ice?"

Deacon Xiao Li rushed forward quickly, and even Hai Dafu, who had been smiling all the time on Jiang Chen's side, was slightly startled.

"Let's go, sea steward, let's go and have a look. ”

Hearing this voice, Jiang Chen's face did not change, and he finally breathed a sigh of relief in his heart.

After all, he had never done this saltpeter ice, but he just drew a gourd according to the "National Chemical Knowledge Handbook".

Now it seems that the chemical industry of removing putty is popularized, and sure enough, it works!

The two of them walked to the edge of the container together and looked inside.

I saw that in the wooden barrel, most of the water that was originally flowing had condensed into ice cubes at this time, and with the dissolution of saltpeter, the temperature was further dropping.

"There really is such a clever method......

Hai Dafu was amazed.

If Jiang Chen casts the immortal method and cools down and freezes this clear water, it will be nothing, after all, martial arts masters can also use the true yuan to induce the weather to change.

But now, it is the secret that ordinary people can grasp such condensation into ice!

"It is rumored that the ancient immortals, who comprehended the Tao and reason between heaven and earth, created all kinds of magical powers, and simplified these kinds of magical techniques, so that ordinary people can also have the ability to win the heavens, but I didn't expect that Jiang Gongzi would have such a method......" Speaking of this, he quietly turned his eyes to look at Jiang Chen.

"Little Doyle. Jiang Chen didn't think there was anything, so he dealt with it casually.

And so it was......

Seeing that Jiang Chen did not deny his words, Hai Dafu nodded secretly, his guess was as accurate as ever!

"Jiang Gongzi, the seven-leaf blood orchid has been saved, and it is ripe and expected, this matter should be reported to Your Majesty. Hai Dafu said busily.

"It's nature. ”

Jiang Chen smiled faintly and exhaled a big breath in his heart.

His younger brother finally ...... Finally saved!

..................

In Jingyang Palace, the empress's bare feet were resting on the case, and she was holding a chapter in her hand for review.

"This old woman really doesn't take me seriously anymore!"

Ji Xianyue bit a mouthful of silver teeth, slapped the piece in her hand on the case, and kicked the air hard.

"Your Majesty is angry. ”

Chu Qing, who was dressed in light armor, stood behind the empress, getting close to her body little by little, and the true yuan surged, eliminating all the heat that had not dissipated in late summer and early autumn.

Chu Qing stuck tightly behind the empress to help her dissipate the heat, and at the same time, he recalled the woman who made the empress gnash her teeth.

Su Muqing, the prime minister of the Great Zhou Dynasty, is called the left minister because the civil officials of the Great Zhou Dynasty respect the left.

In that year, after Ji Xianyue killed the rebel in the 100,000 army, the world was in chaos, and then the left minister came out of the mountain, but after half a year's effort, he solved all kinds of chaos and re-stabilized the mountains and rivers.

Inside and outside the government and the opposition, there are even military and His Majesty, and there is a saying that there is a left minister, and the prestige is extremely high.

And the empress and the left minister, although they were still good at the beginning, and they joined forces to calm the chaos, but after the world stabilized, the contradictions between the two gradually appeared.

Nowadays, although it has not reached the point of being on the same footing, the open and secret battles in the court are also indispensable.

And even if Ji Xianyue's martial arts talent shocks the past and the present, after all, she is only a little girl in the prime of her life, and when facing the scheming Zuo Xiang, she suffered a lot of losses, and she could only lose her temper in Jingyang Palace.

"Hmph! This woman also came to ask about the current situation of the seven-leaf blood orchid, and I said why is she so kind, it seems that she knew that the waste in the Spirit Garden can't even raise a single flower!"

The empress was furious: "If it weren't for the fact that the Seven Leaf Blood Orchid is really useful for my martial arts cultivation, I really want to pull out this flower and throw it on the old woman's face!"

"Now, I have to ask the old woman!"

The more you think about it, the more angry you get, and the more you take a step back, the more you lose.

"Bang!"

In front of the angry empress, the poor case was dealt a heavy blow again.

"By the way, Qingqing, then Jiang Chen went to treat the seven-leaf blood orchid, is there any result?"

After losing her temper, Ji Xianyue's eyes moved, and she looked at Chu Qing, and her eyebrows seemed to ...... Looking forward to it?

Chu Qing shook his head and said, "I'm afraid I'm going to disappoint Your Majesty, that kid surnamed Jiang sat in front of the flowers for two hours yesterday and didn't do anything, so he must be helpless and determined to sit still." ”

"That's ......"

Hearing Chu Qing's words, Ji Xianyue suddenly felt a little excited.

It's one thing to save the seven-leaf blood orchid or not, and in the empress's heart, there are a little other, unspeakable thoughts.

If Jiang Chen can rejuvenate with his magic hands, maybe ......

It's a pity, now it seems that this Jiang Chen is just an ordinary person.

"In that case, then forget it, Qingqing, you go and pass on ......"

"Your Majesty!"

Ji Xianyue was halfway through her words, when suddenly a voice came from outside the hall, interrupting her words.

"Come in!"

She frowned, looked at the personal maid who hurriedly ran in, and reproached, "What's so frizzy?"

"Your Majesty!"

The maid took a breath, saluted respectfully, and spoke quickly.

"That seven-leaf blood orchid ......"

"What's wrong with the seven-leaf blood orchid?" Ji Xianyue stood up suddenly.

"Seven-leaf blood orchid, ...... I was saved by Jiang Gongzi!"
