C317 Gift (1/2)

When Xiao Wen fell asleep, the Luoyang City's street drum had already been rung.

As the lights of the myriad families went out, the Luoyang City, which had been noisy for an entire day, finally fell into silence.

There were still lights on in Taiji Palace. palace maid stood under the long porch silently and listened to the anxious footsteps in the hall as they transmitted confused looks to each other.

His Majesty was usually wise and calm, but today, he was extremely agitated. He paced back and forth, as if trying to convey the displeasure of the world's lord.

His Majesty was unhappy, the servants, the palace maid stood even more solemn, the sound of her breathing was also much softer than before.

A streak of light snaked over, and a smile appeared on the face of the yellow clothed servant in front of the palace gate. The foul air that was restrained in her chest immediately dissipated without a trace, as she took two steps forward, bent down, and shouted with a shrill voice: ”Welcome, Empress Dowager.”

In the lamplight, a beautiful lady in a palace dress lightly waved her sleeves while the attendant stood up and stood to one side.

”Has His Majesty gone to bed yet?” she asked.

”Reporting to the Empress, His Majesty has been within the palace ever since he received the report from the Duke of Lu, and has yet to go to bed.” The attendant replied.

The Empress nodded and dismissed them.

Then, the beautiful lady dressed in the imperial costume entered the hall by herself. She was about to speak when she heard the emperor speak. ”Kuan Yin, do you think there is really a method to extract salt from saline soil?”

Although Li Shimin came from a noble family, he was not a reckless hero like Liu Bang. However, he wasn't some existence that wouldn't touch the Yang Spring Water.

The joke about why he didn't eat minced meat was definitely something he couldn't say.

In fact, he was well aware that the salt in the saline soil was poisonous and could not be eaten.

After eating that salt, one's stomach would be bloated to death, not to mention the fact that it would turn purple all over, making them look extremely strange.

If Xiao Wen was standing here right now, perhaps he would explain the same reason as Li Shimin.

In fact, the salt in the alkaline soil can't be eaten because it's not only green … Pui! Sodium chloride, but also nitrate, phosphorus potassium and other impurities.

If he ate these impurities together, he would be courting death.

It would be strange if he ate too much phosphorus and potassium, and his whole body wouldn't turn purple.

In the future generations, Xiao Wen had seen people who could replenish calcium and iron. He had never seen anyone who could replenish nitrogen or phosphorus or potassium. At most, it would be used as an agricultural fertilizer and sprinkled on the crops.

However, Empress Changsun smiled and said, ”I have already heard of the method that the Han Emperor gave us. I heard that the salt in this alkaline land cannot be eaten directly, and needs to be refined, dissolved, filtered, and analysed. In the end, the salt crystallized is the salt that humans eat, just like some medicinal herbs that are obviously poisonous, but after some special processing, become non-toxic and can even treat illnesses.”

”This salt should be the same. Everything in this world is prepared for humans. As long as the correct method is found, all living things in this world can be used. It's just a path to making salt.”

”Although I don't know if this method of refining salt is correct or not, I believe that there must be a method that can extract the best quality salt from the saline soil.”

Empress Sister-in-Law knew that the Tang Kingdom had a huge geopolitical flaw. That was the lack of salt.

Although Song Ming, who was at the coast of China, had never sold salt to the mainland, and the food far to the west was willing to exchange the salt for the Tang Kingdom's silk spices.

But the Qin and Han dynasties had Bashu, Song and Ming dynasties had beaches, and these great Chinese countries all had their own land for the production of salt. Only the Great Tang Dynasty could only rely on other nations in this regard.

In the east, south and north of Great Tang Dynasty, there were three mountain ranges. Although there was an opening in the northeast, allowing them to travel from Guandong, the Han Kingdom, to Song Ming, the road was inconvenient and easy to defend and attack.
