Li Jiancheng finally successfully transformed the green salt into white table salt, and he was very happy.

"Slow down, Xue Li and Su Dingfang obey orders!"

"The last general!"

"The two of you must keep it a secret today, and you must not say a word to outsiders about what you have seen and heard today, and in addition, quickly bring to the palace the two gentlemen of Muhammad al-Azubn and Caliph Morikud."

"Yes! The last general commands! After Xue Li and Su Dingfang brought in Muhammad Aziben and Caliph Molikud, Li Jiancheng had already finished taking a bath and changed into clean clothes. When Muhammad al-Azibn and Caliph Mori Kud came, they immediately knelt down and saluted Li Jiancheng:

"Your Royal Highness the Crown Prince, your faithful servant Muhammad Azubn salutes you."

"Your Royal Highness the Crown Prince, your faithful servant, Caliph Moriku, has to salute you." Li Jiancheng replied:

"Two gentlemen are exempt. I've been neglecting the two gentlemen these days, and the two gentlemen are still used to living here! Muhammad Aziben and Caliph Molikud stood up after hearing Li Jiancheng's words, but their expressions were still respectful, and they did not dare to be disrespectful. For the last three days, although Muhammad al-Azibn and Caliph al-Molikud ate and drank every day in their dwellings, and went to sleep after eating and drinking, none of them spoke to Muhammad al-Azubn and Caliph al-Molikud, and they were not allowed to go out, and sometimes, eavesdropping on what the guards said:

"Hey! What the hell do you think these two people in it are coming from? Let's watch it so closely here. ”

"Hey! I heard the porter Lao Song say that these two are the two Hu merchants of the Western Regions that His Royal Highness rescued from the market hooligans, and also took back the green salt in their hands, and His Royal Highness the Crown Prince personally ate salt with the two of them. ”

"Yo! It's a good life to hold the two! Let His Royal Highness the Crown Prince test the salt with them. ”

"Hey! Look at what you said, these two 'masters' are not good people, as soon as they entered the house, they were beaten by the two little highnesses with a blue nose and swollen face, this is not counting, if something happens to our prince at that time, the ladies have said it, these two people will be cut with a thousand knives, and they will be buried with our prince together. ”

"What are you talking about?"

"Oh! Sue-sama! ”

"A few of you have stood at your posts, and you have forgotten your last name after only a few days of coming! Be clear, just stand at your post, don't talk nonsense, when the time comes, it will reach the ears of the prince, and I won't be able to save your heads. ”

"Yes, yes, yes! The little one understands. "Every time they heard the city council that guarded them talk like this, Muhammad al-Azibn and Caliph Molikud would touch the head on their necks and be afraid that they would go to see their Allah that day. Now that his head has been saved, his life has been saved, and he has also been involved with His Royal Highness the Crown Prince, the heir of this empire, how can he be unhappy!

"Your Royal Highness the Crown Prince, you are so polite, it is our honor to be able to serve you, and what are you used to and not used to." Although Li Jiancheng was wary of Muhammad Aziben and Caliph Morikud, he was still very satisfied with the attitude of the two of them:

"Two gentlemen, all your green salt in the palace have been bought, and in a few days to pick an auspicious day, the palace will personally take you into the palace to meet the father of the palace, and let the father give you an edict when the time comes, so that you can go to the Western Regions to get more salt like this." As soon as Muhammad Aziben and Caliph Morikud heard that they could meet the supreme ruler of the Tang Empire, they immediately softened with excitement, and Li Jiancheng hurriedly asked people to hold them up:

"Oh my God! O Allah! It is wonderful to be able to meet an emperor in my lifetime, and I believe that this honor is willing to let me die. ”

"Yes! Allah! Thank you for your blessing that I have met such a good master as His Royal Highness the Crown Prince, and for being able to make me so honorable again, thank Allah. Muhammad al-Azubn and Caliph Morikud constantly praised Allah in Islam in front of Li Jiancheng.

"All right, go down! Xue Li, Su Dingfang, you have ordered the whole mansion to hold a banquet tonight, and treat everyone in the whole palace, etc., these days with the father to eat light food, it is also hard for them. ”

"Yes!" Su Dingfang and Xue Li took the order and left. In the evening, Li Jiancheng came to the family banquet living room, Zheng Wanzhen and Yang Yan dressed up to greet them, and the two brothers Li Chengdao and Li Chengxun sat motionless at the table like two little adults.

"Yo! It's all here. ”

"Yes! It's waiting for you! Husband, today's dishes are all made by me and Yan'er, you must try it today. ”

"Okay!"

"Husband, you try this braised pork, which I made with my own hands, and this steamed duck, which is made by Yan'er's sister. And this peeing shrimp. It's all done for you by our sisters, you've worked hard these days, thank you well. Zheng Wanzhen and Yang Yan kept giving Li Jiancheng food, and it was really difficult for the two of them, it turned out that no matter how busy Li Jiancheng was, he would accompany the two of them for a while, but since Li Jiancheng announced the retreat, Zheng Wanzhen and Yang Yan have been difficult to see Li Jiancheng, and several times Zheng Wanzhen and Yang Yan took Li Chengdao and Li Chengxun to see what Li Jiancheng was doing, but they were all blocked by Xue Li, because of Li Jiancheng's strict orders, Zheng Wanzhen and Yang Yan did not dare to disobey casually. Now that Li Jiancheng has finally come out, he is naturally very attentive. Li Jiancheng tasted every dish, and the taste was sweet, but it was slightly astringent. I also felt some fine particles between the teeth. As if seeing that Li Jiancheng was a little dissatisfied with the dishes, Zheng Wanzhen explained:

"Xiao Chengdao and Xiao Chengxun are not used to eating light food, so my sister and Yan'er tried to find a way to use sugar as a seasoning, and I don't know how many ingredients have been wasted these days to develop these dishes." As soon as he heard Zheng Wanzhen say this, and saw that Li Chengdao and Li Chengxun were eating with relish, Li Jiancheng said in his heart: "The current sugar is gray sugar, and generally speaking, it is used as a child's food, and it is really difficult for the two brothers." At such a young age, he suffered with adults. Well! Gray sugar, if this palace can turn gray sugar into white sugar, wouldn't it solve the urgent need again. Thinking of this, Li Jiancheng held the hands of Zheng Wanzhen and Yang Yan silently, and said affectionately:

"Two ladies, it's really hard for the two of you these days. Tonight, the husband will behave well. Zheng Wanzhen and Yang Yan looked at Li Jiancheng shyly, and their eyes secretly glanced at Li Chengdao and Li Chengxun brothers, the brothers don't look at people small, but the ghosts are big, they are all monkey spirits and monkey spirits, and they only care about eating, and they don't look at Li Jiancheng's meaning. The next morning, Li Jiancheng looked at the two women who hugged him, remembered the madness he had with Zheng Wanzhen and Yang Yan last night, and gently took Zheng Wanzhen and Yang Yan's hands away. Got out of bed lightly. To the palace maids and eunuchs at the door, he said:

"The two mothers worked hard last night, you are so waiting, there is something in the palace now, don't disturb the rest of the two mothers. In addition, go and bring Xue Li and Su Dingfang to the palace. ”

"Yes!" Xue Li and Su Dingfang heard Li Jiancheng's call and hurriedly ran in front of Li Jiancheng:

"The last general will see His Royal Highness the Prince, I don't know what His Royal Highness the Crown Prince has to tell Weichen."

"The two Qing families, this palace has another confidential matter for the two Qing families to assist." As soon as they heard that Li Jiancheng had another confidential matter for the two of them to assist, the academic qualifications and Su Dingfang were even more overjoyed in their hearts. Let's go back soon:

"Please ask His Royal Highness the Crown Prince to instruct, and the ministers will definitely assist, even if they go up to the Sword Mountain, and go down to the fire, the ministers and others will not frown." Li Jiancheng nodded, and took Xue Li and Su Dingfang to the courtyard where Li Jiancheng tested the salt first. Xue Li and Su Dingfang felt very strange: "Your Royal Highness the Prince, what's the matter, hasn't the matter of salt been resolved?" Why are you here again? In addition, a stove was built in this courtyard, and a few strangely shaped pipes made of bamboo were inserted into the stove. However, Xue Li and Su Dingfang had doubts in their hearts, and they didn't dare to say anything on their mouths.

"Xue Li, Su Dingfang, you go and get a packet of gray sugar for the palace. I took a large water tank and the clean gauze that I used to go back to the main palace and brought some more to the main palace. There is also lime water and clay pots. Xue Li and Su Dingfang didn't dare to ask more, so they hurriedly went to the warehouse to get a bag of gray sugar and a large water tank. Li Jiancheng opened the sack, stroked the gray candy body, broke a little and chewed it in his mouth, and suddenly a sweet feeling came from his mouth, but then there was an astringent feeling, and there were many rough fibers on his tongue, Li Jiancheng lifted the sack and poured it directly to the big water tank in the courtyard, and in the blink of an eye, most of the sack fell, Xue Li, Su Dingfang and others all screamed. Putting down the remaining half sack of sugar cubes, and pouring the prepared lime water into the water tank, stirring vigorously, the sugar cubes in the water tank began to slowly disappear. Li Jiancheng looked at Xue Li and Su Dingfang, who were stunned next to them, and said:

"Mix them well and strain them with gauze. Just like when you filtered the salt. Xue Li, Su Dingfang and the others all found it interesting, and each took a big wooden stick and began to twist it vigorously in the water tank, but at the same time, they also looked at Li Jiancheng suspiciously:

"Your Highness, we used vinegar at the beginning, but now we use lime, won't all this sugar be ruined."

"You will know after you can't destroy it, Xue Li, you go and make a fire first, Su Dingfang, you go and prepare gauze."

"Yes." Although their questions were not answered, Xue Li and Su Dingfang still complied with the order. After filtering the lime sugar water, a lot of the rough fibers in the original gray sugar cubes have been removed, and several people have realized it, but now there is a strong lime smell in these sugar waters, and it is definitely not good to eat it, everyone looked at Li Jiancheng and waited for Li Jiancheng's next instructions. Li Jiancheng inserted a bamboo tube into the water tank on the top of the stove, and countless bubbles bubbled out in the water tank, and the carbon dioxide combined with the lime water in the water tank to produce white calcium carbonate, which sank to the bottom of the water tank. Everyone present saw this miraculous scene, and as the bubbles bubbled out, the water tank could be seen with the naked eye that there was suddenly a lot of white substance.

"Your Highness, are you the reincarnation of an immortal and can refine some elixirs of immortality?" Only those immortals can see such a spectacle, in the era of the Wuhu Rebellion, the Han people were slaughtered by the Hu rulers, and later Buddhism and Taoism prevailed, the Hu rulers in order to confuse the Han people, resolve the Han people's dissatisfaction with them, for Buddhism and Taoism to vigorously support, stipulate that Buddhist monasteries and Taoist Taoist temples can be exempted from taxes and servitude, in order to avoid taxes, in the peak of monks and nuns, one-tenth of the country's people became monks, Taoist priests and nuns, and later came to the Northern Zhou Dynasty after Emperor Wu took power, Deeply felt the harm brought by the monks to the Northern Zhou regime, ordered all the monks, Taoists, nuns must all return to the world, Buddhism and Taoism weakened in the Great Zhou, however, Emperor Wu of the Northern Zhou Dynasty was in power for only a dozen years before he died, and later Yang Jian Dai Zhou, when he was a child, he lived in the Buddhist temple, and had special feelings for the Buddhist temple, Yang Guang ascended the throne, Buddhism and Taoism have many people who have contributed to the force, and it is the official position of the great seal of Buddhism and Taoism, that is, Li Yuan in order to promote his divine authority of the monarchy, and also claimed to be the descendant of Li Er, the old monarch of Taishang, and vigorously commended the TaoistsTherefore, many people in the world still believe in the flow of immortals. Li Jiancheng just shook his head and said nothing, and when there was no more white substance in the water and gradually became clear, Li Jiancheng stopped inflating and ordered several people to re-filter the water tank and remove the white substance. After re-filtering, the water tank suddenly turned into clear water, and there was no longer that lime taste, so I dipped it with my hand and put it in my mouth, only to feel a burst of sweetness through the tip of my tongue.

"Come, taste it too." Li Jiancheng greeted Xue Li and Su Dingfang: Everyone put the sugar water in their mouths as they said, and their faces showed a look of surprise, and Su Dingfang shouted first:

"Your Royal Highness the Prince, you are really a god." Xue Li also nodded at the same time, he could get such sweet water, even honey was nothing more than that.

"Well, go take out the clay pot, fill it up, heat it, and evaporate the water." Xue Li and Su Dingfang both took out the clay pot and began to heat it, half an hour later, with a large amount of water evaporating, the liquid in the clay pot became more and more thick, and when it was already extremely thick, they ordered to stop heating and slowly wait for it to cool. Ordered Xue Li and Su Dingfang to move all the clay pots back to the room, cover them with lids, and re-emphasize the sense of secrecy before leaving. Early the next morning, Li Jiancheng ordered Xue Li and Su Dingfang to lift the lid of the clay pot that had been completely cooled, and there was already red sugar inside. Just before they could sigh, Li Jiancheng re-ordered Xue Li and Su Dingfang to pour all the sand sugar into the water tank, pour in clean water, mix well, and put crushed charcoal into the water. If it weren't for Li Jiancheng's improvement of green salt and the previous sugar, Xue Li and Su Dingfang would never have done this, Li Jiancheng looked resolute and didn't explain anything? Xue Li and Su Dingfang had no choice but to do so. This time the wait was longer, and after another day, Li Jiancheng asked everyone to filter the sugar water, and then heated, evaporated, and cooled. On the third day, everyone was stunned when they reopened the clay pot, the clay pot was snow-white, and they put the snow-white sugar into their mouths with their hands, and the sweetness did not decrease, but this appearance was much better than the red sugar. Li Jiancheng looked at the stunned Xue Li and Su Dingfang, and said proudly:

"See, this is the real sugar, without the slightest impurity." Subsequently, Li Jiancheng took out a few more clay pots, all filled with sugar, and gave them to Li Gang, Yu Zhining, Wang Gui, Xu Jingzong, Huang Wenqing, Di Zhixun, Xiong Kuohai, Kuoling, Wei Zheng and other auxiliary ministers of the Eastern Palace, Xue Li and Su Dingfang also had it. Li Jiancheng also has his wife and children, and the two little guys, Li Chengdao and Li Chengxun, have eaten all the sugar in the entire clay pot, and everyone is full of praise for this sugar. Li Jiancheng said loudly to everyone:

"This sugar will also be a key to open the way to the solution to the salt shortage."
