Daming: Grandpa Emperor, please get up and sit on my throne!

Forbidden City, Alchemy Bureau.

"It's done, it's done. Let's try it out and see the effect!"

"It's already been prepared. This piece of silk is covered in a lot of grease, dust, and... let's quickly wash it with that... oh, soap that Your Majesty mentioned."

"I'd really like to see if, by simply modifying the recipe for pancakes using oil and sodium carbonate... you could produce something with far greater cleaning power than pancakes? It would also look much better."

"Wow! It really is! It washes so clean! My hands were just covered in grease, but after a quick wash, it's completely gone! Sodium carbonate... something Your Majesty casually mentioned during class, and it actually has such a wonderful use!"

"Fellow Daoist Zhang must have listened carefully. I didn't pay much attention during the previous class."

"..."

The Alchemy Bureau, from the very beginning, did not live up to its name. It was more like a source of chemical production. Now that Zhu Yunhuan had taught them a lot of basic chemical knowledge and principles, these people would of course do what they should do.

At this moment, the people gathered in the courtyard of the Alchemy Department, who seemed a bit noisy and boisterous, were none other than Zhang Yuqing, Ma Rui, Yuan Gong, Liu Yuanran... and other prestigious Taoist celebrities and alchemy masters.

However, these people who were respected as "immortal masters" everywhere outside, squatted on the ground with a look of surprise, looking at a piece of cloth being scrubbed and hands that had just been washed clean of oil.

If you don’t know them, you might think they are grandpas or old men squatting on the street corner watching the excitement. Even heavy snow cannot extinguish their enthusiasm.

Just as everyone was amazed, they heard a familiar voice coming from outside the gate: "Your Majesty has arrived!!"

Hear this sound.

Everyone immediately raised their heads, their faces filled with excitement, joy, and reverence, and asked, "Your Majesty has arrived?"

As they spoke, several people stood up, straightened their robes, lined up solemnly and neatly, and waited with their bodies slightly bent.

Soon, I saw that handsome young face.

They all bowed their hands and said, "Disciples, we greet your Majesty!" Their eyes were filled with undisguised respect, admiration, and even admiration.

They are obviously the so-called highly respected Taoist "famous men" and "immortal masters", each of them is in their forties or fifties if not in their sixties or seventies, but at this moment they act like young juniors seeing their elders!

This look of respect.

It is definitely not something that can be brought by the so-called status or imperial power.

Only sincere respect and admiration can make people feel this way!

After all, for Zhang Yuqing, Liu Yuanran and others, the shock that Zhu Yunhuan has brought to them is already countless. The countless basic chemical principles that they have never heard of or seen before have already directly shattered their original cognition and worldview.

In their eyes, Zhu Yunhuan was the ancient Greek god of chemistry. He was their "master" whom they recognized from the bottom of their hearts, an "elder" who taught them and answered their questions, regardless of age.

"No need to be so polite." Zhu Yunhuan said indifferently.

Everyone stood up, their eyes filled with a desire for knowledge. They looked at Zhu Yunhuan with burning eyes and said:

"Your Majesty is here today, but are you going to give a lecture?"

"It's a coincidence that Your Majesty has come today!"

"Your Majesty mentioned the application of sodium carbonate in a lecture earlier, saying it could be used to make a 'soap' that's much more useful than soap. I've been exploring it on my own, and just got some results today!"

"Yes, Your Majesty, we just tried it, and it worked perfectly!"

"..."

When talking about soap, a group of Taoist bigwigs immediately started talking non-stop as if they were presenting a treasure. How could they still act like masters?

Zhu Yunhuan glanced at the crowd.

A faint smile appeared on the corner of his mouth, and he nodded with satisfaction, saying, "Soap? I saw it, and the finished product does look somewhat like it."

He raised an eyebrow and thought to himself, "As expected of the best worker in the chemical industry! He has gradually grown into a mature worker!"
