Chapter 458: The Doctor of the Waterworks Department Got Mad

Yuanruan: [That’s great. After all, you haven’t had any systematic training, so you’re quite talented.]

System: [That's true. After the doctor from the Du Shuisi came up with this method, many people in later generations also liked to add some ingredients when burning stones. Later, some people added some more ingredients and actually made three-in-one soil.]

Yuanruan was very surprised when he heard this: [Sangangtu? The predecessor of cement? It's amazing.]

This one word "amazing" immediately made everyone look sideways.

People can't help but wonder, what is cement? What is cement? How powerful are they?

System: [Yes. Although cement mortar still has its shortcomings, it is better than today's glutinous rice paste walls. It is extremely strong and the building will last longer...]

As people listened, they were amazed: it turned out to be such a good thing!

The officials were all a little agitated, especially the doctor from the Water Conservancy Bureau who was in charge of building the canal. If Qi Yue hadn't intervened in time, this man would have been exposed because of the focused look he gave Yuan Ruan.

Everyone was expecting the system to tell them the formula, but unfortunately the system only talked about the development history of cement, but did not explain how the mortar was specifically synthesized.

Later, the system actually changed the topic, and the court officials felt disappointed and anxious.

The Junior Secretary subconsciously looked for the Crown Prince's location. After a moment, he realized that the Crown Prince, who was the best candidate to take over, was not there!

The Junior Chancellor sighed in his heart and hesitated for a moment. Just as he was about to step forward, he heard the Third Prince's still pale voice.

The Third Prince asked, "Sir, why does adding some vinegar make the stone easier to break?"

The doctor from the Water Conservancy Bureau looked at the Third Prince in confusion, but still answered honestly, such as how he happened to think of it, and finally carefully added that it was just his own random guess, and he boldly tried to verify it carefully.

The Third Prince nodded seriously and said, "Master, since vinegar can damage rocks, if the enemy attacks the city and they use vinegar to splash our walls, will the walls break?"

The doctor of the Du Shui Si was confused. Why would His Royal Highness the Third Prince ask such a stupid question?

He explained dryly: "It shouldn't happen. On the one hand, the soldiers guarding the city won't give them a chance to be jealous, and on the other hand, they can't burn it..."

The Third Prince nodded as he listened, and suddenly asked, "So that's how it is. A large amount of vinegar will damage the rocks. Is there anything that can make the rock wall stronger after adding it?"

The officials raised their heads suddenly: !!!

Here it comes, the familiar feeling is here!

Your Highness, has your pot tradition been passed down?

"Hiss." The Junior Secretary clapped his hands suddenly and said in a very cooperative manner, "Your Highness the Third Prince is right! Sir, Doctor of the Water Conservancy Department, do you have any new research on the construction of canals and city walls, such as the preparation of glutinous rice?"

The doctor of the Water Conservancy Department also understood: the Third Prince and the Junior Secretary were singing the same tune in an attempt to bring up the topic of cement formula again.

The doctor of the Du Shui Si said: "It's not that I don't have any ideas. For example, many of our earthen bricks are made from boiled glutinous rice soup mixed with lime slurry containing gravel and clay. So, if the thickness of the glutinous rice soup is improved, will there be any..."

System: [The glutinous rice is thick...it doesn't matter much. 】

Du Shui Silang was delighted and continued, "There is also soil. Sometimes you can see that different colors of soil have different hardnesses when mixed together..."

System: [Ha! This person is really sharp. The mineral components in the mud and sand are different. For example...]

The doctor of Du Shuisi's eyes became brighter and brighter.

He usually likes to study the formulas of these things, and has accumulated many questions in his mind, but unfortunately no one can answer them for him. However, now, the system can answer them all.

Thinking of this, the doctor from the Water Conservancy Department became more and more excited as he spoke, and at the end he was not concerned at all with the formula of the bricks. He almost wanted to recount all the difficulties he had encountered in building the canal over the years.

When Shao Zhanshi heard the words of the Doctor of the Water Conservancy Department, he was like a wild boar that had been released from its cage. He went crazy all the way and figured out "what kind of weather is best for opening the mountains"... Even the system went astray and there was no way back.

Shao Zhanshi became anxious.

He desperately winked at the doctor of the Du Shui Si: "San Cement! Cement! The key point!"

But the doctor from the Du Shui Si Department was so drunk that he saw nothing.
