Crazy and bad again, the princess is the best in Beijing

Shi Wanwan nodded. "That's right. After burning the stone, it turns into lime. When it comes into contact with water during the lime process, it releases a lot of heat, which can cook eggs."

"The limestone is mixed with clay, gypsum, and iron ore to become cement."

"Cement alone will solidify, but it's not very strong. If cement is reinforced with iron rods, it will become very strong after it dries."

As she spoke, she mixed the cement, fixed the steel on it, and poured it in.

Shen Yi had originally just come to watch the fun, but when he heard this, his eyes lit up:

The old monster is about to use his ultimate move!

He said to his followers, "Hurry up and write down everything the princess said!"

The attendant responded and immediately began recording.

Shi Wanwan continued, "People only know that iron ore contains a lot of impurities, and that pig iron is brittle and weak, making it only useful for making simple farm tools."

"Iron impurities can be removed through high temperatures and forging. When the impurities are reduced, it becomes refined iron."

"Fine iron can be used to make tougher and sharper knives or farm tools."

"So, based on this idea, if we raise the temperature of the iron smelting process even higher, we can smelt the iron into water."

"In this process, more impurities can be removed and higher-purity iron can be obtained."

"Then, through the process of quenching and high-temperature rehydration, the toughness of the iron is further increased, and sharper and more indestructible weapons and tools can be made."

"I figured these out myself after visiting the blacksmith shop. If you're interested, you can give it a try."

She knew a lot about iron and steel making methods, but they involved a lot of chemical formulas and reactions, and these people wouldn't understand even if she told them.

She was able to become a doctor of Western medicine because she had excellent grades in chemistry when she was in high school.

This knowledge can be explained by junior high school chemistry, and it is child's play compared to the chemistry knowledge she learned after studying medicine.

It was also because the technology of the time did not allow it, otherwise, let alone removing some impurities from the iron block, she could have made steel for them!

Someone from the Ministry of Industry was there, so they discussed with her the possibility of refining iron into water.

In everyone's eyes, how could iron, which is so hard, turn into water?

But people in the Ministry of Industry know a little more about this. They know that many things have their own melting points, but the temperature is not high enough.

Shi Wanwan did not hide anything and started discussing it with the officials from the Ministry of Works on the spot.

This part of knowledge is too professional for ordinary people, and they simply cannot understand it!

Shen Yi didn't understand any of this and was completely bewildered, but that didn't stop him from asking someone to write down their entire conversation.

Tian Huaijue was very proud: "My aunt is really amazing, she knows everything!"

Meng Yunting looked at Shi Wanwan who was chatting with officials from the Ministry of Works, her eyes full of admiration.

She had been to the blacksmith shop many times and had never thought about so many questions, so she felt that she was not as good as Shi Wanwan.

But Shi Wanwan is her friend, which means she is also very powerful.

Pei Yushu originally planned to announce the verdict directly, but after hearing the conversation between Shi Wanwan and the officials from the Ministry of Works, he decided to wait until they finished speaking.

He didn't quite understand their conversation, but when he saw the shining eyes of the Ministry of Works official, he knew that Shi Wanwan was right.

He looked at Shi Wanwan. The girl was calm and confident, and her whole body seemed to be glowing.

He suddenly understood why Shi Wanwan had been so calm and composed after the incident, because she was confident.

She knew that she only needed to speak out what she was thinking, and that would be enough to shatter the ridiculous speculation and rumors.

She usually looks quirky, but at this moment she is calm and reliable. Pei Yushu can hear the sound of his own heartbeat.

Xie Xuanzhi looked at Shi Wanwan like this with a smile on his lips. In his eyes, she was supposed to be so radiant, and no one could hide her brilliance.

Shi Qingmei could not accept this fact. In her eyes, even if Shi Wanwan was a little stronger than her, she was only a little bit stronger.

Now, Shi Wanwan has become so outstanding without her noticing, and has become someone she can never forget. How can she be willing to accept this?

She pulled out the hairpin on her head and wanted to rush over to kill Shi Wanwan.

But before she could move, Xie Xuanzhi picked up a fruit on the table and threw it at Shi Qingmei, and she couldn't move at all.

Xie Xuanzhi's eyes were full of disdain. No one could disturb Shi Wanwan's highlight moment.

Although Zhao Zhongze was stupid and disliked Shi Wanwan very much, he was the prince taught by Emperor Qianyuan himself, so he still had some basic vision.

He knew from the eyes of the officials of the Ministry of Works that if all the things proposed by Shi Wanwan could be verified, the national strength of the Tang Dynasty would be greatly enhanced.

He looked at Shi Wanwan with complicated eyes. When did this cousin, whom he had always hated, become so powerful?

By the time Shi Wanwan's Ministry of Works officials had finished their discussion, it was almost dark.

Pei Yushu cleared his throat and said, "If the princess hasn't had enough conversation with the officials from the Ministry of Works, please arrange another time to talk. I must announce the verdict today."

Several officials from the Ministry of Works hurriedly said, "Please come in, Sir Pei!"

Pei Yushu said loudly, "After investigation, it has been determined that Princess Yongning Shi Wanwan did not steal the blacksmith's work. She has nothing to do with this murder case and is released immediately!"

Tian Huaijue immediately led everyone to cheer, "Aunt is the best!"

"Master Pei is wise!"

"Aunt is very talented, she would never do such petty theft!"

Pei Yushu slammed the gavel, and everyone fell silent. He continued, "After investigation, it was found that the timing of Shi Qingmei's appearance at the blacksmith shop was extremely strange."

"This officer has sufficient evidence to prove that she is involved in the murder at the blacksmith shop."

"She also colluded with the people in the blacksmith shop to give false testimony, intending to frame Princess Yongning. Her actions are extremely despicable. She will be imprisoned first, and her sentence will be determined after her other crimes are investigated."

"As for those who gave false testimony in the blacksmith shop..."

He looked at Shi Wanwan when he said this: "I wonder if the princess will hold them accountable?"

Shi Wanwan looked at those people. They were all huddled together and trembling.

She thought of the blacksmith's shop owner and sighed inwardly, "Although their behavior is bad, but..."

After she said this, she walked around the group and said, "But this princess will not punish them as they are first-time offenders and have recently lost their families."

The families of the blacksmiths looked at Shi Wanwan with gratitude.

Pei Yushu said, "Since the princess doesn't mind, I will give her a lighter sentence."

"You all caused trouble at the Dali Temple before, and you have received some punishment. Today, each of you will be given two more strokes of the cane, and this case will be closed."

Everyone breathed a sigh of relief and knelt on the ground to express their gratitude.

Pei Yushu slammed the gavel and said, "Adjourn the court!"
