"This is the Nine Turns Golden Pill that makes people become the pinnacle of the prefecture level?" Li Shimin asked curiously.

"Who did Your Majesty listen to? How could this golden pill make everyone directly become the peak of the prefecture level? When they were in Yizhou, they became the pinnacle of the prefecture level because they were almost all prefecture-level people. Like Du He, he can only be at the peak of the Xuan level, and giving it to his son is to wash the scriptures and cut the marrow for her and lay the foundation, so that it will be much easier to cultivate the Heavenly Silkworm Heart Sutra. Situ Changfeng explained.

"I see! This is always getting more and more outrageous! Li Shimin said slightly embarrassed.

"That's true, my son's body is weak and her internal organs are also weak, so that she can not only recover quickly as an ordinary person, but also have a solid foundation and practice martial arts quickly." Situ Changfeng nodded and said.

"My son has eaten the Nine Turns Golden Pill, so I don't need to practice martial arts, after all, this child has suffered too much since he was a child, and if he can be like an ordinary person, the mourning family will be content." The eldest grandson asked with concern.

"You're right, but the son is congenitally damaged, and if he doesn't cultivate the Heavenly Silkworm Heart Sutra, even if he has nothing to do now, he won't be able to live long!" Situ Changfeng shook his head and said.

"Then let her cultivate." When the eldest grandson heard this, he hurriedly touched his son's head lightly and said.

"If you take this pill, she will fall asleep for nine hours, just let her lie down!" Situ Changfeng looked at the son who was like eating jelly beans, and said with a smile.

When the eldest grandson heard this, he picked up his son and entered the inner room.

"Some small moves of the Yang family, I already know, all this is also expected, this time the Western Turks dispatched, not only Tuguhun, Tubo has signs of sending troops, the Eastern Turks, the Xiongnu, also stationed troops on the border, so there are no soldiers and horses to support Yizhou.

Fortunately, you have achieved a beautiful battle, otherwise once the soldiers come to Yumen Pass, I am afraid that the surrounding war will be inevitable. Li Shimin said gratefully.

"With Your Majesty's strategy, the princes of the court are sitting in all directions, how dare you move, Your Majesty only needs to divide and break the extreme!" Situ Changfeng complimented.

"Divide and break! This is the consistent policy of the imperial court, but it is easy to say, but it is difficult to do, after all, the enemy country is located around the Tang Dynasty, there is not much conflict, and it is difficult to let them kill each other! Difficult! Difficult! Li Shimin sighed.

"It's just because they have no conflict of interest, only eternal interests, no eternal friends!" Situ Changfeng remembered a word, so he replied casually.

"There are only eternal interests, no eternal friends! Aiqing said it so well, I don't know if you have a good plan to teach me! Li Shimin's eyes lit up, and he looked at Situ Changfeng expectantly and said.

"The minister said a little bit of superficial opinion! Please also ask Your Majesty to set the axe right! If something is wrong, don't blame your majesty. Situ Changfeng arched his hand and said.

"Aiqing, but it doesn't hurt to say it!" Li Shimin waved his hand and said.

"I think! If you want to deal with the Turks and the Xiongnu, the simple summary is to win over a group, attack a group, and divide a group......" Situ Changfeng said drawing on the experience of later generations.

"Aiqing wait!" After Li Shimin finished speaking, he summoned the living room, and then sat down and listened to Situ Changfeng.

As soon as Situ Changfeng saw someone writing and recording, he knew that this was a special record of the emperor and the queen's concubine, and these were all materials for the official historian, so he didn't dare to slack off, and began to play seriously.

"The minister thought that he could do it many times, win over the close to the Tang Dynasty and the weak tribes, buy their wool, and sell them some salt tea; Divide powerful tribes, such as the Han Dynasty, or send people to divide, buy, assassinate, or sell them more luxury goods, such as fine porcelain and silk, so that their high-level people are greedy for pleasure; The blow, of course, is those tribes that are not big or small, they are not strong, and they are just used to weaken their strength, and they can also have some unexpected gains. Situ Changfeng explained.

"Wonderful! Wonderful! What Aiqing said is very subtle, but there are still some problems in it. Salt tea is not too much at the moment, how to sell it in large quantities, and attack their middle tribes, aren't you afraid that they will unite and take a bite. Li Shimin high-fived and admired, and then excitedly asked new questions.

"Back to Your Majesty, the minister has a law, which can produce a large amount of salt, as for tea, it only needs to encourage the people to plant a large amount, and it is planted in the mountains and wastelands, which will not delay the cultivation of grain, but also have an additional income." Situ Changfeng explained.

"Aiqing's words are true! There's a way to increase salt massively! Li Shimin got up and grabbed Situ Changfeng's arm, and asked with wide eyes.

"How dare the minister bully the king!" Situ Changfeng hurriedly assured.

"Aiqing, come quickly!" Li Shimin asked excitedly.

As early as the beginning of the conversation between the two, there was no one else in the hall, and now there is just one more living man who works hard, so the conversation between the two is not afraid of leakage.

"When the minister was in Yizhou, there was a salt lake on the grassland, its water was very salty, but it was inedible for people and animals, and if it was eaten for a long time, it would swell, lose sight and other problems, or die, and the herdsmen called it a poisonous salt lake.

Once, after a heavy rain, I went to check and saw many white particles on the edge of the lake, similar to salt, but there seemed to be many other impurities.

After thinking about it, the minister realized that this was the substance left behind by the lake water being dried by the sun, so the minister asked people to level a piece of land, pick up the lake water, and let the sun shine. Sure enough, after a few days, the ground was full of white particles, and after tasting it, it was indeed table salt.

And the surface layer is the same as the refined salt, and those variegated particles are all below.

So the minister collected the salt on it and let the Turks eat it for several months, without any problems at all. "Situ Changfeng This is a method that he only thought of when he discovered the saline-alkali lake, and he finally succeeded after many experiments.

"How's this yield?" Li Shimin asked with concern.

"A thousand people can compare to ten salt wells in Shuzhong, especially in summer! There's no way around it in winter.

However, the minister heard that the sea water is also salty, and there is also a large poisonous salt lake between Longyou Road and Tuyuhun.

Moreover, the minister was wondering if the salt in the lake could be separated from the poisonous substances after it was dried, so could the salt mines in the mountains be integrated into the water first, or dried in the sun, or boiled in a pot to obtain refined salt. Situ Changfeng continued.

"Good! Good! As Aiqing said, in the future, the people of the world will no longer worry about having no salt! Li Shimin's hands trembled with excitement, and he pulled Situ Changfeng's wrist hard, and said with a shake.

"These methods are also the minister's thoughts for a while, how specific, we have to send people to experiment, but these technologies are not yet mature, and they must not be known by outsiders, otherwise others will walk ahead of us, it will become a joke.

Yizhou Yantian, the ministers have been destroyed, only the ministers and guards know, and other places are still for Your Majesty's discretion. Situ Changfeng said seriously.
