It seems that making money, even in the backward Tang Dynasty, is not an easy task. It requires long-term thinking and strict planning.

He sighed, feeling negative, that's all, at least he still made a lot of money.

Shen An's mind was quick and he quickly adjusted his mood and turned the ship around.

With Li Shimin's support, Du Shui Ye is able to secure his position. He is not the stubborn person Shen Quan is.

This well and the water in the well are now his resources. In addition to supplying good water to the imperial city, he must make proper use of the added value of the well.

The well water in the small tank has almost been separated. Although the water from Yujing is of high quality, it is still a natural water source and inevitably contains various metal ions, lime and other impurities.

Now, after neutralization and filtration of the alum solution, all the impurities have precipitated. Ah Qian looked at the yellowed slag at the bottom of the jar and wondered: "Weird, the water from Yujing also has scum!"

"This is the best water in the capital!"

"This is how natural water is. As long as it is treated, the water quality can be further improved." Shen An scooped out a ladle of water and looked at it under the sun. Sure enough, it was clear and translucent, better than pure natural water.

Unfortunately, alum water purification has side effects. It is aluminum ions that can adsorb impurities in alum.

Excessive intake of aluminum is harmful to the human body. It may affect intelligence and cause mental retardation. Of course, this side effect is extremely slow and will only occur after long-term consumption.

Otherwise, make it a high-end small bottle of drinking water and sell it in small quantities.

In Shen An's eyes, there are business opportunities everywhere, and he can make money even by grabbing a handful of loess. While he was sitting there dreaming about getting rich, the courtyard door was knocked open again!

"It's not good!"

"Something big happened!"

Fang Yiai barged in almost staggeringly, out of breath.

Shen An put down his work, walked over calmly and handed him a cup of tea.

This man was always startled, and he didn't take it to heart at all.

"What's going on?"

"Speak slowly."

Ever since she overheard her parents' conversation, Fang Yiai rushed to Shanhefang without stopping. Until now, she was in a panic and her brain couldn't function normally at all.

All I kept saying was, "It's broken, something big has happened!"

Seeing him like this, the calm Shen An couldn't keep calm anymore. He suppressed his temper and waited for a long time before Fang Yiai recovered.

"Shen An, that jade plaque was given by His Majesty!"

"You shouldn't sell!"

"ah……"

Shen An's brain suffered another nuclear attack. There was a bang on the back of his head, and a stinging pain surged up.

"Don't be anxious, talk carefully!"

Fang Yiai took a deep breath, drank two more cups of tea, and finally adjusted her mood. Then she relayed the overheard conversation to Shen An in detail.

Firstly, Shen An was originally interested in the origin of the jade plaque. Secondly, even his dull mind realized the seriousness of the matter.

Li Shimin was kind to his ministers and often gave them his favorite things, such as calligraphy treasures and swords.

But I have never seen him reward anyone with a personal jade token.

The phoenix and orbs on the jade plaque were all decorations often used by the royal family. Why didn't he notice it at the beginning, and he stupidly sold it, thinking he had made a huge profit.

Li Shimin's loud voice suddenly sounded in his ears: Is Shen Quan's jade medal okay?

well enough?

Bar?

Damn it, the origin of this jade plaque must be quite complicated.

The two of them were as anxious as ants on a hot pot, especially Shen An.

He suddenly thought that now he had become Li Zhi's savior. With this bad boy's virtue, he would come to his door in less than ten and a half days.

At that time, if his fate is unfavorable and he meets Li Shimin again and brings up the jade plaque, what will he do?

"Erlang, can you think of a way to steal the jade token?"

"What?"

"Steal it out?" Fang Yiai looked at Shen An blankly, and Shen An was also anxious and confused, and said: "I will return all the money to you, you can think of a way."

"This...is really not possible."

When things have reached this point, Yi Ai can only tell the truth.

"You don't know that Lao Fang regards the jade plaque as more important than his life. He hides it in his arms every day and never leaves his body for a moment."

"I simply can't do it."

"Moreover," when he was about to start talking, he paused again. Shen An hurriedly asked: "What's wrong?"

Fang Yiai's mouth curled up like a crab, and Shen An narrowed his eyes, feeling an ominous premonition.

"Erlang, who told you that jade tablets are sacred objects?"

"Mrs. Fang?" he asked tentatively.

"No..." Fang Yiai lowered her head, not daring to look at Shen An. Shen An patted him on the shoulder and told him not to worry.

He can bear it whether it is a blessing or a disaster, he just wants to know the truth.

The trust of his friends doubled Fang Yiai's confidence. He gritted his teeth and finally spoke.

"Because of this jade plaque, my mother and Lao Fang had a quarrel. I eavesdropped outside the window and found out the truth."

"My mother persuaded Lao Fang that the jade plaque should be returned to you, but Lao Fang refused to obey and kept it no matter what. Shen Lang, in fact, I am no less worried than you are. You don't know Lao Fang's temper. He does things Always considerate and extremely decent.”

"But this time, he actually took the risk and kept the jade plaque with him. This is really strange!"

"With my mother's reminder, Lao Fang will definitely hide the jade plaque even more tightly. I won't be able to get it at all."

If so, it's going to be tricky.

The water that was spilled cannot be recovered, so Shen An can be thick-skinned and try to get the jade token back. But looking at Fang Yiai's nervous look, you know how much Fang Xuanling values ​​the jade token, even if he If you want it, Laofang won’t give it to you.

Sad!

"Mr. Shen, I ask you something, and you must agree!"

Fang Yiai, who had always been laughing and joking, suddenly took Shen An's hand and looked at him with a solemn expression. Shen An was extremely stressed.

"If you have anything to say, just say it." The corners of his mouth twitched and he smiled unnaturally, for fear that something would happen to the second roommate again.

"You must not tell His Majesty that the jade plaque is in Lao Fang's hands."

"Don't worry, I won't tell you!" Someone also took the second-in-command's hand and shook it again and again.

Fang Er, Fang Er, are you stupid?

The jade medal is now Shen An's concern. How could he mention it to Li Shimin so easily?

Shen An's heart was in a state of turmoil, and he could neither sit nor stand.

No matter how much he calculated, he never could have guessed that the ancestral jade medal was actually a gift from Li Shimin. Now that he had saved Li Zhi's life, according to the normal development of the plot, he would definitely have to show it in front of Li Shimin's eyes in the future.

If one day he thinks about the jade plaque, where can he get it?

Where can I find a 3D printer?

But the problem is that things like jade plaques cannot be copied in 3D!
