Ming Ruo and Si Haochen walked in the direction of Yunlai Inn. Today, there are many stalls on the street, and many people are talking in a low voice.

"Do you know why Princess Nanrong's convoy stopped just now?"

"Why?"

"The palace car collapsed."

"Ah... Is that palace car made of paper? How could it collapse?"

"It may be that the princess is too heavy, hahaha..."

"However, that princess is really tall, and the wife of Zhao Butuhu's family is half a head short..."

"Really? That's too high..."

"When the princess changed the carriage, I saw it with my own eyes, it was so tall and strong..."

"I heard that this princess is going to marry our Donghuan's prince..."

"Which prince should I marry? Kong Wu's third prince is better. If it were the weak fourth prince, I'm afraid..."

Mingruo's mouth twitched. If the Eighth Princess heard the discussions of the melon-eating crowd, she would be so angry that one Buddha would be born and the other Buddhas would ascend to heaven.

Mingruo was completely sure at this time that he was not dazzled just now, and the two silver lights should be hidden weapons and other things. The carriage collapsed because it was attacked, but the strength was very accurate. The carriage went forward for a long time before it broke. Even if it was checked, it would not be as good as the teahouse where they were dining.

Mingruo raised his head to observe Si Haochen's expression, and could not see any clues. Mingruo sighed, he didn't even notice it when he "conspired to commit the crime", and it was even more impossible to find anything now.

It's too consuming brain cells after guessing: "Did you do it?"

"I can only say..." Si Haochen smiled slightly at Mingruo, "I didn't do it alone."

According to Si Haochen's estimate, the car would collapse only after walking the next street, so that it would not be blocked on this street and affect their return to the inn. But he did not expect that the national teacher who "ignored the world" also took action...

"Ah..." Ming Ruo smiled and held Si Haochen's arm, "You must have ruined the god-like senior brother..."

"We are taking action at the same time. Why is it that I was leading him to ruin him? It wasn't him who led me to ruin me?" Si Haochen smiled dissatisfiedly. This time it was just a small punishment and a big warning. In the future, the Eighth Princess will dare to bully his princess, so don't blame him for killing him.

"Then you two are quite in tune with each other." The two silver lights did appear at the same time, "What hidden weapon did you use?"

"A piece of silver."

"It's amazing!" If you really use some hidden weapon and don't recycle it in time, you will easily be caught. But this broken silver is not like a "tool of crime". Secondly, it is picked up and spent without waiting for someone to investigate.

Mingruo and Si Haochen walked back to the inn all the way, and Mingruo bought several fresh and interesting gadgets.

As soon as they entered the door, Ah Yi stepped forward and reported, "Master, the emperor's people have come here and will arrive tomorrow."

"Oh." Si Haochen curled a smile on his lips, "You go and arrange it and go to Dongshan Villa tomorrow morning."

"Yes." Ah Yi took the order and left.

Mingruo's eyes rolled. At the beginning of this trip, Mingruo felt that Si Haochen was in a hurry. He was very relaxed and contented in the traveling.

But, according to Ayi's opinion, Emperor Danxu was looking for them, right?

"Is something wrong?" Ming Ruo pulled Si Haochen's sleeve.

"Don't worry, it's okay." Si Haochen leaned on the soft couch, patted the seat in front of him, "Come here."

Mingruo sat over and grabbed a strand of hair from Si Haochen's chest and circled it: "Is there anything that is difficult to deal with? You can tell me, maybe I can help."

"A small matter is a small matter, and you don't need to work to be a beloved concubine." Si Haochen remembered another thing, "The coal I found in the northwest before is much resistant to burning than charcoal. Lu Qiaojiang said that if you use it well, you can refine a large amount of refined iron." Si Haochen held Ming Ruo's cheek, "Do you know how much he has made, huh?"

Mingruo's eyes flashed slightly: "Coal can also be calcined into coke. If it is refined with coke, it can produce metals that are tougher than refined iron."

Si Haochen was stunned. He knew that there were metals that were tougher than fine iron, such as black iron. But black iron ore was more scarce than gold mines and could not be used to build weapons and armed forces: "Are you talking about black iron?"

"No." Ming Ruo took out a scalpel from his medical bag, "That's it."

Si Haochen had seen Ming Ruo use a scalpel more than once, and he also knew that the small blade was extremely sharp. Si Haochen took the scalpel and played with it in his hand: "What kind of ore was used to make it refined?"

"It's iron ore." Mingruo used his knowledge of physics to roughly talked to Si Haochen about the principle of steelmaking, and then said, "You can understand that the more thoroughly the impurities in iron ore are removed, the tougher the metal can be obtained. This process of removing impurities requires the help of high temperatures. Therefore, if you can get fuel at a higher temperature, you have the opportunity to get purer iron.

Of course, with the current technical means, it should be difficult to make pure iron like a scalpel, but it is more tough than refined iron, and it is completely possible to achieve it."

"Ruoer." Si Haochen pressed the little girl into his arms, "How can you be so smart? You really can't become a little fairy?"

Si Haochen knew very well that what Mingruo knew was not explained by a word of "intelligence", but apart from intelligence, he didn't know what to say. The more he saw her uniqueness, the more he was accompanied by her joy, there was also inexplicable panic. He had to be strong enough to be qualified to stand on par with her to protect her.

"..." Ming Ruo rolled his eyes, "Are you not afraid of me being a fairy?"

"What are you afraid of?" Si Haochen raised his eyebrows.

"Are you afraid I will eat you?" Mingruo smiled and looked treacherous, "Let me tell you a story about a ghost."

"Tell me." Si Haochen supported his head with one hand and leaned on the couch.

Mingruo talked about it later and deliberately stretched out his hand and clawed it on Si Haochen's chest: "Just digging out Wang Shengxin and eating it."

Si Haochen was unmoved and let her play.

After Mingruo finished speaking, Si Haochen smiled and said, "Thank you for your hard work in your beloved concubine, I have received education for my husband."

"Ah?" Ming Ruo was a little confused. This was a ghost story and not an idiom story. What did he teach?

"Didn't I mean that those beloved concubines are all demons and ghosts that can't be close to you." Si Haochen looked like I understand everything and you can rest assured, "I have recorded it for my husband."

"..." Ming Ruo instantly petrified, she really had no intention of this.

"Puff." Si Haochen thought that his princess looked so cute.

"Forget it, just do whatever you want." Everyone has their own opinions, and my boyfriend sees himself defending his sovereignty...

"Tomorrow we will go to Dongshan Villa to see the corn we planted." Si Haochen walked down Shun Mingruo's hair, "I'll ask someone to take Lu Qiaojiang over there, and you can teach him how to make coke."
