On the shores of Puchang, vast stretches of mudflats stretch as far as the eye can see, a white expanse.

Liu Wei, accompanied by Sharde, Baishi, Chen Lian, and several officials from Loulan City, rode along the edge of the mudflats for dozens of miles.

Following them were the cavalry of the Imperial Guard and Shard's personal guard.

Looking at the vast lake before him, Liu Wei was filled with emotion.

It should be noted that in later generations, this place became the core area of ​​Lop Nur, a forbidden zone of death.

Unexpectedly, 1,800 years ago, there was such a vast and misty lake here.

The water glistens, the aquatic plants are lush, and migratory birds fly about, creating a vibrant scene.

It is the second largest saltwater lake.

Meltwater from the Tianshan and Kunlun Mountains converges to form the Tarim River, Peacock River, Cherchen River, and Shule River, before flowing into this area.

As Liu Wei walked, he searched for information about Lop Nur from later generations.

Suddenly, my eyes lit up – yes, it's potash fertilizer!

What is potassium?

Potassium is one of the essential elements for plant growth and an important component of the three essential elements of fertilizer (nitrogen, phosphorus, and potassium).

As the saying goes, "Nitrogen grows roots and stems, phosphorus grows leaves, and potassium is needed to bear fruit," meaning that without potassium, there can be no harvest.

In the 1980s, scientist Peng Jiamu led an expedition team deep into Lop Nur in search of potassium!

Although Peng Jiamu disappeared in Lop Nur, the scientific expedition team successfully found potassium, thus solving the critical resource problem.

Now that Liu Wei has arrived at his fiefdom in Wuyuan City, Shuofang, the system has rewarded him with 1,000 jin each of sweet potato, hybrid rice, and corn seeds.

Because it is winter now, Yao Guangxiao has already had one hundred experienced farmers, who were rewarded by the system, cultivate sweet potato seeds.

We'll wait until next spring to cultivate and plant corn.

The Hetao Plain is located at a high latitude, and due to its climate, hybrid rice can only be tested in parts of the Yellow River basin and is not suitable for large-scale planting.

However, this potassium fertilizer can improve the soil, which can not only increase the yield of sweet potatoes and corn, but may also allow hybrid rice to survive in the Hetao region.

Liu Wei immediately jumped off his horse and walked into the depths of the mudflats, his steps uneven.

"Your Highness, be careful!"

The crowd exclaimed in surprise.

Liu Wei waved his hand, walked to a shiny puddle, squatted down, grabbed a handful, looked at it, and then stuck out his tongue to lick it.

It's both bitter and astringent!

In his previous life, he was an ordinary employee at a small company, but he studied science and engineering in school and had a certain foundation in physics and chemistry.

Furthermore, he also took the elective course "Postpartum Care of Sows" and read three great books: "Barefoot Doctor's Handbook", "Farmland Irrigation Practice", and "Militia Training Tutorial". He has quite a bit of knowledge about masturbation!

Otherwise, how did he purify the crude salt in the Hetao region?

These crystals are the water from Puchanghai, a saltwater lake. As the water flow decreases in winter, the lake level drops, exposing the lakebed, which is then exposed to the sun.

There was also a pitted and uneven brine that hadn't been dried but was extremely concentrated.

These crystals and brine can be filtered through water to separate them, and the resulting lake salt is rich in potassium.

Of course, we don't have the advanced technology of later generations, but under the current conditions, the only way to extract salt is by sun-drying.

Master math, physics, and chemistry, and you'll be able to go anywhere in the world without fear!

The powerful system increases the population every second, and it has units, generals, and equipment, but it doesn't have a technology tree!

At this moment, Liu Wei regretted spending all his time playing games in college. If he had learned more, he could have put that knowledge to good use!

However, this knowledge is sufficient for most purposes.

Anyway, knowing that the lake water here is rich in potassium, everything is fine.

Liu Wei immediately waved to the back!

Shen Lian, Bai Shi, Shard, and a group of officials from Loulan rushed over.

Bai Shi and Shard were already puzzled by Liu Wei's strange behavior, not understanding why he had brought them to the lakeside.

"You Loulan are guarding a great treasure without even realizing it!"

Seeing the curious looks on everyone's faces, Liu Wei smiled faintly, "The water from this large lake can be used to make salt! It's not only edible, but it can also be used as fertilizer!"

"We've heard about salt production from this lake, but without the Han people's skills, the salt produced is just coarse, bitter salt."

"But this is the first time we've heard of it being used as fertilizer!"

Upon hearing Liu Wei's words, the officials of Loulan responded in unison.

"That's because your methods are wrong!"

Liu Wei laughed and said, "If I were to send someone, they could immediately produce fine, white salt, as white and fine as the snow from the Kunlun Mountains!"

Shard and Whitestone's eyes lit up.

They heard from merchants on the Silk Road that the royal family and nobles of the Han Dynasty used salt that was as white as snow, and that it could also be used as a mouthwash to make their teeth as white as ivory.

I never imagined that the Puchang Sea near Loulan City could produce such snow-white salt.

In this way, thanks to the convenience of the Silk Road, Loulan's wealth will reach an even higher level than before!

If Loulan becomes even more prosperous under her leadership, it will be a fulfillment of her father's expectations.

Sharde looked at Liu Wei, her eyes sparkling with affection.

This prince not only saved Loulan from the iron hooves of the Xianbei and Cheshi people, but also planned to make Loulan more prosperous and a pearl on the Silk Road!

She was about to become his concubine!

I just don't know when this prince will officially marry her and make her the king's woman?

"Rest assured, everyone. I have appointed General Xue as the Grand Protector of the Western Regions Protectorate. He will not only protect the safety of the various countries in the Western Regions, but also lead the people of those countries to a better life!"
