After returning to the palace, Zhangsun Wuji first looked for a blacksmith to forge a set of rollers according to the blueprint.
Then he went to the palace to see Li Shimin.
When he told Li Shimin about the function of the roller and how it was invented by Qin Yun, Li Shimin widened his eyes.
"Are the wheels you mentioned really that powerful?”
"That's right, Your Majesty. You didn't see it, but when several grain carts rolled off the cliff, even Hou Junji couldn't find a way to get them up. In the end, it was the Crown Prince who pulled out these rollers and pulled the carts up.”
"His Highness the Crown Prince said that this roller could lift anything weighing thousands of pounds. General Hou and I tested it on the spot, and it turned out to be true.”
Hearing Zhangsun Wuji's words, Li Shimin stepped forward and carefully examined the roller.
This was invented by his son, so he naturally had to look at it carefully.
"Demonstrate it for me now.”
"Alright, let's use the stone lion outside the hall to demonstrate."”
Under Zhangsun Wuji's command, a few guards tied up the stone lion.
Then, under Li Shiming's gaze, Zhangsun Wuji began to pull the chain.
The stone lion slowly rose under the influence of the iron chain.
"How is this possible?"
Seeing this, Li Shi Min's eyes widened.
He knew how heavy the stone lion outside the hall was. It weighed at least a thousand pounds.
But now, he was actually hung up by Zhangsun Wuji with one hand.
"Your Majesty, how is it? This invention is not bad, right?”
Li Shi Min was shocked,"That's right, I didn't expect Yun 'er to have such abilities. You're indeed my son."”
"If this thing is used to build the city wall, it will definitely save a lot of effort.”
"Your Majesty, the Crown Prince said that it would be more convenient to draw water if it was used on a well."”
Li Shi Min was stunned, then he nodded and said,"Yes, I wouldn't have thought of it if you didn't say so. Pass down my decree now and mass produce it before promoting it.”
"Yes, right, Your Majesty, I have another matter to report.”
"What is it?"
"Recently, the aristocratic families in Chang 'an City seem to be buying a large amount of food. I don't know what they are trying to do.”
" Buying food in bulk?"
Li Shi Min frowned and said,"These aristocratic families are all doing business. Isn't it normal for them to purchase food in large quantities?”
"It's mainly because the grain they bought this year is several times more than before.”
Li Shi Min was shocked.
One had to know that these aristocratic families would only purchase food in large quantities under special circumstances.
Now that they suddenly increased their acquisition, could it be that something big was about to happen?
"Father."
At this moment, Princess Chang Le walked in from outside.
"Zhi 'er, why are you here?"
After these days of recuperation, Princess Chang Le's illness had already recovered.
Princess Chang Le ran over and hugged Li Shi Min's thigh,"Where did Brother Yun go? I haven't seen him for a long time. I don't know why, but I miss him so much when I can't see him.”
Li Shi Min was startled, and then a bitter smile appeared on his face.
He thought to himself,'This silly girl, he's your brother. Of course he'll think about it if you can't see him.'
Upon recalling that it had been a while since she last visited Qin Yun, she said,""How about this? Since Imperial Father is free today, I'll bring you to see him.”
"That's great. I can see Brother Yun now.”
"Ancestors, I'll leave the promotion of the rollers to you.”
"Don't worry, Your Majesty. I will definitely complete the mission.”
Zhangsun Wuji cupped his hands.
Li Shimin brought Princess Changle, Fang Xuanling and Du Ruhui and left the palace.
In White Cloud Monastery, Qin Yun treated the commoners every day as usual.
When he saw Li Shiming with Princess Changle, Fang Xuanling, and Du Ruhui, he said in surprise,"Your Majesty, why are you here?"
"Brother Yun."
Without waiting for Li Shimin to speak, Princess Changle ran over and grabbed Qin Yun's hand.
"Zhi 'er said she missed you, so I brought her here to see you."”
Qin Yun stroked Princess Changle's head and said with a smile,""Princess, you've just recovered from your illness.”
Princess Changle blinked." I'm bored to death staying in the palace every day. Brother Yun, can you take me to play?"”
Li Shimin suddenly felt his heart ache when he saw how much Princess Changle liked Qin Yun.
The two of them were siblings. If their identities were made public, he could get Qin Yun to bring Princess Changle out to play.
But now, he couldn't do that.
"Zhi 'er, come here quickly. Your Brother Yun still needs to treat the people."”
As he said this, Li Shimin found that the people's mouths were dry and cracked, as if they hadn't eaten for days.
"What's wrong with these commoners? Why do they look so listless?”
Qin Yun said," These commoners are refugees from other places in Chang 'an. As the aristocratic families have been purchasing food in large quantities recently, it has resulted in a shortage of food. Therefore, even if they beg, very few people will give them food.”
"Strange, why would these aristocratic families suddenly purchase a large amount of food?" Li Shi Min frowned.”
Qin Yun said," It's because Chang 'an Fortress is about to have a rainstorm. When the time comes, there will be a flood. They are buying food now so that they can earn a fortune when the flood occurs.”
Hearing this, Li Shi Min said in surprise,"How did they know that there would be a flood? And how did you know, young abbot?”
