"Your Majesty, these solutions need to undergo multiple filtrations before arriving at the boiling workshop here."

"The Imperial Grandson's cooking methods are divided into coal-fired cooking and solar-powered cooking!"

"Solar energy?"

Seeing that Li Shimin was interested, Zhang Anan immediately pointed to a large, gleaming silver pot.

"It's that big pot. As long as you point the pot at the sun, it will concentrate the sunlight and boil the brine!"

Li Shimin immediately became interested upon hearing this.

"Have someone demonstrate this for me!"

"promise!"

Zhang Anan was an old man here. When the craftsmen saw that Zhang Anan wanted to see the solar cooker, they immediately told two people to operate the lever to control the solar cooker to face the sunlight, and then place the iron pot filled with brine at the focal point of the solar cooker.

Li Shimin observed very carefully, not missing a single detail. However, even so, when the brine boiled, he was still completely bewildered—how could this stuff be boiling!

However, just as he was about to touch it, Li Jue stopped him.

"Grandpa, be careful!"

"Li Jue?"

"I'm just curious why this thing can be heated!"

Upon hearing this, Li Jue immediately took out a piece of wood and placed it at the focal point of the solar cooker. In almost the blink of an eye, the wood was ignited.

"Grandpa, this thing is extremely hot. If you reach out and touch it, you might accidentally touch the hot spot and something terrible could happen!"

"Oh oh oh..."

"Can you tell me why this thing heats up?"

"able!"

"Actually, this thing is very simple. It's just like how we feel warm when we bask in the sun. The solar cooker uses its concave shape to concentrate more light into a single point, which can then provide heating."

"Oh oh oh..."

Li Shimin listened, nodding his head, but felt like he was just wasting his time.

Even though he didn't understand, he was still very happy. After all, this powerful weapon belonged to his eldest grandson, so he didn't need to worry about it being harmful to him.

"Da Sun, how much salt can your workshop produce every day?"

Li Jue calculated with his fingers and said.

"Under normal circumstances, it would be tens of thousands of kilograms. With a little overtime work, it wouldn't be difficult to gather 100,000 kilograms!"

"hiss……"

Upon hearing this, Li Shimin gasped. Looking at the overwhelming array of unnamed production equipment on Li Jue's side, and then at the group of good-for-nothings following behind him, he couldn't help but feel a surge of emotion.

"Times have changed!"

Li Jue nodded upon hearing this.

"Grandpa, times have indeed changed!"

"I know why you've come. If you're really worried about these members of the imperial clan, I can give them some shares so they can live a life free from financial worries."

"But... they can forget about getting involved in the workshop's operation and management. Anyone who dares to lay a finger on it will have their hand chopped off!"

Princess Jiujiang and the others had long been rendered powerless by Li Jue. Now, seeing how advanced Li Jue's workshops were, completely overwhelming their traditional workshops, they were utterly convinced.

Therefore, before Li Shimin could speak, they all knelt down with a thud.

"Crown Prince, we have no other desires, we only beg you to spare our lives, and we will be content, sob sob sob..."

"You don't need craftsmen anymore?"

"No, I don't want it!"

"Stop making a scene?"

"Stop fooling around!"

"good!"

Li Jue was never a stingy person. Seeing that they had finally quieted down, he immediately said generously.

"I'll give each of you a workshop. You can choose between salt and iron!"

"ah?"

Li Jue's sudden generosity stunned everyone, and some of the more timid ones even shook their heads repeatedly.

"No, no, no, we dare not accept it..."

Li Shimin also looked at Li Jue with a face full of surprise.

"Grandson, what exactly do you mean?"

Li Jue smiled bitterly upon hearing this.

"Grandpa, industrial development is a long and arduous task; relying on your grandson alone is not enough..."

"For the Tang Dynasty at present, producing tens of thousands of catties of steel per day is already quite good, but it is far from my grandson's goal!"

"My grandson's goal is to produce hundreds of thousands, millions, or even tens of millions of kilograms of steel per day!"

"hiss……"

"Grandson, what do you need so much steel for?"

Li Jue chuckled upon hearing this.

"Build a train!"

"Build a ship!"

"Build an airplane!"

"Build cannons!"

"Build machines, build bridges, build dams..."

"I want to transform the Tang Dynasty into a paradise on earth!"
