Because of Rong Zhen, Lu Zheng changed his previous decision, because Rong Zhen, as the highest military commander of the entire northern border, also has the status of a prince, and can directly inquire about the local administration.

Qingluan was a little hesitant to speak.

Rong Zhen shook his head gently at him, and then said to Lu Zheng: "If you want to find the prisoner, I'm afraid it won't take too long, how about within three days?"

Lu Zheng also knew that Rong Zhen had a heavy responsibility and had just recovered from a serious injury. He was very surprised that he came to pick him up in person. He didn't intend to delay his time, but if this case was delayed, the evidence would only become less and less, so he was willful. But he didn't expect Rong Zhen to be so tolerant of him, which made Lu Zheng relieved and a little apologetic to Rong Zhen.

"Three days are enough. I will definitely solve the case as soon as possible."

Rong Zhen nodded, and suddenly reached out and touched Lu Zheng's head: "You seem to have grown taller."

Lu Zheng was stunned by his sudden action.

Rong Zhen raised the corner of his mouth slightly: "You go and do your work, I won't follow you."

Lu Zheng quickly came back to his senses, his eyes wandering around but not looking at him, hesitating: "Your injury hasn't healed yet, you should rest first."

Rong Zhen sighed: "You too, remember to take the medicine before going."

"Oh...oh."

After Lu Zheng left the room, Qing Luan frowned and said to Rong Zhen: "Your Highness, your injury..."

Rong Zhen shook his head: "It's okay. Don't stay here, go help him."

"Your subordinates have to protect your safety."

"It's not that the king is sick and can't get up, Why do you need such protection? " Rong Zhen knocked on the table lightly, "He is unfamiliar with the place and he is still young, I am afraid he will be bullied. You follow him, at least you represent my face, do you want me to go there in person?"

"I dare not." Qingluan sighed in his heart, and felt deeply that his own prince was too concerned. He saw that Master Lu was very capable, and his eyes seemed to see into people's hearts. How could he be bullied? I am afraid that others were bullied by him and helped him count money. But since Rong Zhen had given such an order, Qingluan did not dare to disobey, and could only obey the order and leave the room.

They borrowed the courtyard of a local gentry, which was not far from the crime scene, so Qingluan used a few jumps to get to Lu Zheng's side.

Lu Zheng was a little surprised when he suddenly saw Qingluan: "Brother Qingluan, what do you want?"

Qingluan held the sword and said lazily: "Master Lu, is there anything I can help you with?"

Lu Zheng knew from his attitude that he must have been ordered by Rong Zhen. He smiled lightly: "I don't have anything to do, I just need a few guards to help. You should go back to protect the King of Chu, his safety is more important."

Qingluan frowned: "Although I think so, but since His Highness has already ordered it, I'd better do it. You can send me with confidence."

"I really don't need any help." Lu Zheng laughed, and seeing Qingluan was still stubborn, he compromised, "Okay, in that case, I'll trouble Brother Qingluan to accompany me to the other houses where fires broke out."

Qingluan nodded, and after a while asked again, "Do you really think that someone else set the fire, and it was more than one house?"

Lu Zheng shook his head, "I'm not sure, but I think it's a bit suspicious that there are so many fires in such a small area. I asked the people here before, and although fires are often easy to break out here, they usually happen in summer or autumn, and not just in a small area."

"Then what kind of person do you think the murderer is?"

"We have to first determine whether this is just a simple incident or a serial arson case." Lu Zheng sighed softly, "Although I hope it is the former."

Qing Luan touched his chin: "I heard that the murderer used something that can even burn soil and rocks. I have never seen such a thing, except..."

Lu Zheng was listening to him carefully and asked hurriedly: "Except what?"

"Except for the fire thunderbolt!"

The two came to the courtyard where the fire first broke out in the ruins of the post station. Qingluan said, "Zhuque once sent people to sneak into the Jie camp and stole several fire thunderbolts. After they were ignited, the power was extremely strong. A wall as thick as a palm would be blown up in an instant. If this thing could not touch water and was prone to malfunction, I'm afraid that the cities ahead would have been captured by the Jie people."

Lu Zheng shook his head: "That thing did not make a loud noise." In fact, after hearing Qingluan say this, Lu Zheng suddenly had a bold guess, but he couldn't be sure for the time being.

Qingluan guessed: "Maybe this Fire Thunderbolt can be used in other ways without making a loud noise?" He suddenly felt excited. "If someone can really make something like this, can't our Northern Frontier Army use it to fight back against the Jie people?"

Lu Zheng couldn't help but say: "But that man is a murderer!"

Qingluan didn't care at all: "What does it matter? People who achieve great things don't care about trivial matters. As long as he can help us turn defeat into victory, such a crime is not worth mentioning."

Lu Zheng was completely Unable to agree with his words, he could not help but argue: "The country has its own laws and the family has its own rules. This man set fire and killed people, which is a heinous crime. How can we let him go so easily just because he was willing to do so?!"

Qingluan sneered: "I don't know if Master Lu has heard that killing one person is a thief, killing ten people is a bandit, and killing ten thousand people is a marquis. Not to mention that this person has committed a crime now, even if he is a bandit with a long history of evil, as long as he can help my Great Xia to drive out the Jie people, he will naturally be a hero praised by everyone."

"Please forgive me for not agreeing with this!" Lu Zheng raised his voice, "If he committed a crime, he committed a crime! If the court really rewards him for this kind of thing, how will the people of the world view the court, and how will the people who abide by the law deal with themselves!"

Qingluan calmed down, and looked at Lu Zheng with a smile: "Master Lu, you seem to have made a mistake. This world belongs to the Rong family, and this law is also the law set by the Rong family."

Qingluan's words were like a basin of cold water poured on Lu Zheng's head. He suddenly realized that compared to the modern rule of law, in Daxia, everyone is used to the fact that everyone is born unequal. What they rely on is not the law, but the rule of the superior. In fact, Rong Zhen also said something similar, but Lu Zheng did not realize how important this matter was at that time, and Rong Zhen was in the ruling class. But when the same words came out of Qingluan's mouth, it was completely different.

This is a huge gap brought about by the times, and it is not something that can be eliminated by his words. But he will still say what he should say.

Lu Zheng took a deep breath and said to Qingluan seriously: "If there is a minister who is extremely corrupt but has great talent, and the water conservancy project he built saved the lives of tens of thousands of people, is his contribution great or too great? If this person embezzled money for flood control, causing tens of thousands of people along the coast to suffer, then can his contribution still be worth it?"

Qingluan was speechless.

Lu Zheng said again: "What you said about killing one person is a thief, killing ten people is a bandit, and killing ten thousand people is a marquis. This may be realistic, but it is wrong! This is a satire of reality. If you kill ten thousand people to become a marquis, what about killing one hundred thousand people? If the court wants to rule the country in this way, then the superiors can do whatever they want, and the people can only live in fear. How can such a country last long!"

Qingluan's face turned pale, but there was no way to refute it.

Lu Zheng let out a breath. He had been holding these words in his heart for a long time. He used to be confused by such things, but now he is no longer confused. He knew that his views were different from those of people nowadays, and he didn't think he had the domineering spirit that could make others submit with just one word, but this didn't stop him from sticking to his own ideas.

Perhaps this idea seemed unreasonable or outrageous to the world, but Lu Zheng knew that he was right, and he knew what he could do.

Even if there were tens of thousands of people against me, I would still go!

Rong Zhen heard the entire conversation between Qingluan and Lu Zheng. He followed Qingluan out because he was afraid that Qingluan's straightforwardness would embarrass Lu Zheng, but who would have thought that he would hear such a conversation.

Compared to Lu Zheng, who was still immature in front of him at the time, he is now very clear about his own ideas and the path he wants to take.

Rong Zhen suddenly felt a subtle sense of pride, as if he was watching a green fruit gradually grow and mature, the feeling of witnessing the other person's growth. He knew that Lu Zheng was different from them. He said that to Lu Zheng at the beginning, on the one hand, to remind him, and on the other hand, he wanted to see if this young man could really clear the fog and see the path he wanted to take.

Lu Zheng did not disappoint his expectations. Even after going through so many things, he always maintained his unique temperament.

Maybe this is why he had such thoughts about him at the beginning. Rong Zhen thought.

This was originally just an unpolished rough stone, but now under the scrutiny of worldly affairs, this gem has gradually emitted a dazzling light. Rong Zhen did not intend to possess the gem privately. He hoped that Lu Zheng could show his talent and walk his own path firmly. He hoped to be a protector rather than an owner.

Rong Zhen took two steps back. He knew that Lu Zheng could handle these things well and did not need his unnecessary worries. He was not a daughter who grew up in a noble family. His sky was so vast, and he should not break his wings in the name of pampering. He

only needed to quietly guard by his side and witness the day when he was dazzling and famous all over the world.
