In the gloomy room that blocked the light, four Dao boys stood on the floor, and this environment made them think that the town envoy in front of them was going to plan a conspiracy that would not see the light, and that they would have the honor to participate in it, and their status would be improved in the future.

The silhouette of Li Zhen's envoy was hidden in the shadows, and he could only be heard floating out: "Using the iron casting skills learned from Zhao Laodao, I also cast a few containers, and it looks like this." ”

He took out the paper from his sleeve, and Lu Tu stepped forward to take it with both hands, and when he leaned in front of his face, he saw that it was a thing that looked like a Dan furnace, but the size of the logo was only about a foot. He was suspicious in his heart, what kind of Dan can be refined in such a big Dan furnace?

"After Daochang Zhao starts alchemy, I will teach you how to dispense medicine and how to test, now go back to the caster first, and I will personally go to Guanli on the day of alchemy."

They were confused, they didn't understand Li Siye's intentions, it didn't seem to be a conspiracy, could it have something to do with alchemy?

"Let's go down."

The four of them withdrew from the room and walked out from the back door of the town envoy's mansion under the leadership of Yan Xiaosi.

On the way back to the Taoist temple, the curiosity and suspicion in the hearts of the four of them became more and more serious, and they speculated: "Tell me, what is this asking us to do?" Dispensing again, and casting again? ”

"I know," Lu Tu said with his hands behind his back and pretending to be profound, "Master said that the Danding can be refined into a golden pill that prolongs life, and it can also be refined into a very poisonous poison. The general may have asked us to refine poison and throw it into the river from upstream, which could poison tens of thousands of troops downstream. ”

"Nonsense, what poison pill can turn an entire river into poisonous water? In my opinion, the general is going to ask us to practice a kind of strong vajra pill, and after eating it, our strength can increase by five times, and we can even jump ten feet high. Feed it to the Shule army, and 6,000 people can destroy 100,000 troops. ”

"Alas, this is still like a little, but it's not, in my opinion, the general is engaged in a kind of formation eye, when the formation eye is opened, there will be fog, and there will be a spirit in the array, but if a strong enemy enters it, he will lose his mind and kill each other."

"You're even more unproductive, but I heard from Master that when you put too much saltpeter in alchemy, it's easy to fry the furnace. Do you think this is ......?"

The other three scoffed: "Can you have a little imagination and just fry?" The envoy Li Zhen personally intervened? There is Yanzhou stone grease in the army, which burns endlessly after being ignited with phosphorus fire! Also fry! ”

The four of them walked towards the Taoist temple in a noisy commotion.

……

In the early morning of the second day, Li Siye bid farewell to Silu and Bian Lingcheng outside the gate of Shule City, and the young Silu put on the Turkic collared robe, wore a felt hat, and stepped on sheep felt shoes, like a Guo Jing.

His eyes wandered back and forth in the crowd, but he didn't see the figure he wanted to see, and he couldn't help but panic and be disappointed in his heart, blaming him for being stupid, and he couldn't ask yesterday, "Can you come to see me tomorrow?"

He retracted his gaze in disbelief, and after saluting Li Siye, he turned over his horse, stretched out his hand and pulled the reins of the horse, and finally glanced at the city gate, and his eyes suddenly lit up.

He saw the blue and green skirt Mei Er walking out with his sister-in-law, she was wearing a goose-yellow cardigan, with a concubine-colored veil between her arms, and the golden hairpin swayed and smiled and beckoned to him.

A smile also spread across her face, and she straightened up and bowed to everyone, thinking that she was looking at herself now, and that the way he was now was exactly what she expected.

As the horse team drifted away, he turned back on his horse and looked at the city wall of Shule in the distance, as if there was still a touch of green skirt there. Bian Lingcheng saw the nostalgia in his eyes on the side, so he raised the corners of his mouth and smiled: "Little Khan has looked back several times, is he worried about whose little lady?" ”

The attendants around the overseer laughed loudly.

"The little khan must have never been in the business, and he doesn't know how to pick flowers and break branches."

Si Lu was furious, but he didn't know how to fight back, the mouths of these vulgar laymen were blasphemy against her, how did the philistines know what he thought, she was different from anyone else in the world, she was a star rising in the sky, and she could only be seen from afar.

……

Zhao Daochang received the dansha he wanted from the merchant from the Central Plains, which was as much as thirty catties. There is everything on the Gobi Desert in the Western Regions, but there is no such thing. For these cinnabars, he didn't know how much money he spent, how many favors he sought, and it took a lot of effort, and he even wrote five or six letters, so that his senior brother could spend money from Jiugong Mountain to consign Dansha to the merchants who came and went to the Western Regions, and it also cost three times to bring Shule to pay for the goods, which was more expensive than buying a hundred catties.

The rest of the other materials, he needs to look for in the vast land of the west of the moraine, in the past all the Taoist priests of the Nine Palaces, he is best at collecting materials in the wild, all kinds of stones and soil, alum, crystal, chicken blood, amber, gold, silver, copper, iron, tin ore can be distinguished.

The four apprentices were not afraid of hardship, and they carried cloth bags full of ore he collected, in addition to these things, they also collected a lot of saltpeter, and learned from Daoist Zhao to distinguish the difference between real saltpeter and miscanthus salt.

After returning to the Taoist temple, Zhao Zheng prepared to pound the medicine hammer and stone mortar, and the three apprentices not only helped the master to pound the materials, but also made a large wooden hammer and a stone mortar the size of a pot, and put the saltpeter into it and mashed it until it became a fine salt-like crumb, and charcoal and sulfur were also concocted in the same way.

When Lao Dao opened the fire alchemy, he was also curious to see what the apprentices were tinkering with, what was the use of them dealing with so much saltpeter?

When they took out the Dan furnace, but it was something the size of a melon, Zhao Daochang couldn't help but sneer, how could such a large Dan furnace be enough, but if it was used to deduce the alchemy process, it could be tried.

General Li also rode to the wall, it seemed that he was very concerned about the effectiveness of his refining pills, Lao Dao was suddenly full of energy, and he didn't need his apprentice to fan the fire, he personally waved the banana to master the fire, and the fiery red hearth reflected his face.

He turned his head from the Dan furnace, squinted his smile and said loudly: "General, please be relieved, I have been immersed in the Dan Dao for decades, this furnace can definitely be made, if it becomes two Dan, you and I will each eat one Dan!" ”

Li Siye shook his head and said, "I don't take pills. ”

"If you don't take the pill, can it be dedicated to someone?"

"Not really."

He laughed loudly, turned around and continued to refine the pill, and those disciples ran back and forth, running to Li Siye from time to time to report to him. He also said that the proportion of saltpeter is seventy into five, the proportion of sulfur is one into two, and the charcoal is not very clear. He didn't have any suspicions, Dan Fang said that there was a fire alum method, in order to instantly make the fire blazing and increase the cohesiveness between the Dan stones.

It seems that there is also alchemy over there, and Li Zhenenvoy also went to see it in person, as if he was more interested in that Dan, and the apprentices were tinkering with it, and it was not a climate. After the golden pill here is completed, he will be attracted by this furnace pill, mixing the gold with mercury water and then melting it into the pill, after becoming a pill, the color is golden and gives birth to a strange aroma, and anyone who desires immortality can not refuse when he sees it.

Zhao Laodao suddenly turned off the fire, and a puff of white smoke came out of the mercury extractor on the top of the furnace, which enveloped the entire Danfang in immortal qi, and he carefully put the shovel in it and took out three purple-red pills densely covered with golden spots.

He laughed excitedly, and was about to let General Li also palm his eyes, but he saw Li Siye covering his ears with his hands and looking into the distance, and his three disciples were also hiding far away, waiting for a reaction to turn around...... Rumble!

The explosion set off a small area of wind and waves, and the rumbling sound was already ringing in his ears.

Zhao Laodao staggered, the pill in the shovel fell to the ground, he shook his head vigorously and wanted to lie up, but a sharp tinnitus sounded in his ears, which was even more terrifying than the thunder of the low clouds, almost bursting his eardrums.

He looked up in the direction where the voice came from, where the courtyard wall had collapsed in half, and there was a deep pit in the ground, and the apprentices' melon pill furnace had been blown to pieces. Here Li Siye was pulling the reins of the black horse hard, and the horse was frightened by the explosion, so he cowered back and jumped and peed out.

He stroked a handful of his long messy hair, got up from the ground in a rage, pointed at the four culprits and yelled, "You bastards! I told you in advance that saltpeter is easy to fry! How are you all matched! It exploded so violently! ”

Who knew that these four apprentices had no shame on their faces, looking at Lao Dao with a trace of sympathy in their eyes, and then looked at Li Siye, as if waiting for his decision and fate.

"What's going on?" Zhao Laodao panicked and asked Li Siye.

Li Siye turned over on the horse, and said indifferently while hugging the horse's neck: "Daochang Zhao, please forgive me for not telling you in advance, this is what I want, it has something to do with alchemy, and it has little to do with alchemy, it can help me defeat the enemy, kill the enemy in a hundred steps, break the city in a thousand steps, if the thunder shakes, it will alarm all directions." ”

Zhao Zhengyi's eyes suddenly widened, and his mouth recited the name of the Taoist temple: "Thunder Temple? ”
