She rushed to the clinic and begged Fu Zhun to have his men find some limestone, clay, and sand.

"What new idea have you come up with this time?" Fu Zhun was puzzled, but he naturally complied with her and sent out guards.

Zhou Li sighed with a worried expression, "Could it be that the young boss is tired of studying food and wants to switch careers to become a craftsman? No way! My happiness for the rest of my life depends on the young boss!"

That's utterly absurd. Su An scoffed and couldn't resist kicking him. "An eighty-year-old mother drinking porridge? You're shameless and disgusting!"

Zhou Li immediately grinned slyly and dodged away, but the next moment he received a gloomy warning look from Fu Zhun.

He shut his mouth and sheepishly slipped away.

He was trying to create some tension for the prince, didn't he? Look how big the small business is growing!

Su An winked and smiled, deliberately whetting Fu Zhun's appetite: "If you want to know about my new research, then you'll have to trouble Your Highness to find me the materials."

Fu Zhun understood Su An's personality; the fact that Su An had taken the initiative to bother him meant that she must be in a hurry.

He beckoned and dispatched his secret guards again.

Clay and sand were easy to find, but limestone took a while to find; it was eventually discovered at the foot of a mountain.

Su An couldn't wait to take the limestone to the kiln pit and calcine it at high temperature to produce lime. Then he buried himself in his work and began to ponder it.

She fumbled around in the yard trying to figure out the proper mixing ratio of the three types of soil, but found it was more difficult than she had imagined.

I tried several times, but either I added too much water and the soil became too soft, or it just wouldn't mix at all!

"Sigh! What a long and arduous journey!" Su An's back ached, and he collapsed on the ground, covered in dust and exhausted.

When Fu Zhun came over, he saw her supporting herself on the ground, looking sadly at the sky.

Her whole body was covered in dust, and her clean little face was also covered in mud.

"What trouble have you encountered?"
