After all these twists and turns, I saw Su Xiu, and from the mouth of this eyewitness, I learned that the arsonist was the arsonist, but this arsonist was not what Zhu Changluo wanted.

After all, Zhu Changluo and the others are not Li Mi, for the existence of black impermanence, whether they believe it or not, they are in awe in the end, and they can't be like Li Mi, not only are they not in awe, but they also ignite their fighting spirit.

Their thoughts are actually similar, maybe Su Xiu encountered intimidation and used these words to trick them, or maybe Su Xiu was really frightened, so he mistook the arson.

But one thing is undeniable, according to what Su Xiu said, after the arsonist set the fire, the fire grew rapidly, and it was not time to rescue at all.

Through the investigation of the fire site, Li Mi had already come to this conclusion, so from this aspect, Su Xiu's description was not nonsense.

In the end, they are knowledgeable, not to mention anything else, just talking about Li Mi's side, there are many strange people, especially Sarufei Sasuke, who wants to hide like a ghost and swagger in front of ordinary people, it is not impossible to do it.

Especially since it was already night, it should not be difficult to achieve such an effect under the cover of darkness and firelight.

In any case, Su Xiu's description is so much, he is indeed an eyewitness, and he does provide a suspect, as long as he finds this person, he can solve the case, clear the suspicion, and rescue Zhu Youxiao.

However, the problem seems to come back again, this person is even more difficult to find than Su Xiu, if he is really the eighth master black impermanence, then he has to die in the underworld to find it, or find a heavenly master like Zhang Guoxiang to summon the soul.

Even if he is not black and impermanent, he can confuse the real with the false, which shows his ability, such a character is intentionally hidden in the capital full of people, and it is even more impossible to find it.

Zhu Changluo also knew this very well, so he told Zhu Youxiao's situation, and then said to Su Xiu: "Are you willing to testify for Wu'er and go to the Golden Palace to talk to the emperor?" ”

Although Su Xiu is only Qin Tianjian's subordinate to the eight pins, he does not dare to discuss the government in vain, Qin Tianjian has always maintained neutrality, and will not openly support Zhu Changluo or Zhu Changxun, let alone get involved in the dispute over the country, this is the rule of Qin Tianjian.

However, Su Xiu is an upright person, as his father said, he is a very disciplined person, in the words of later generations, he is upright and principled.

He firmly believed in what he had seen and heard, if Zhu Youxiao was wronged because he did not come forward, his conscience would not be able to pass, so he promised Zhu Changluo.

"The minister is willing to go to the temple to testify!"

When Zhu Changluo heard this, he was overjoyed, but he turned his head to look at Li Mi, who was still frowning and didn't seem to approve of this approach.

"Sir? Sir, think it's inappropriate? ”

Zhu Changluo could see that Li Mi did not hide it, and said to the two.

"I also have something to say, Zi Bu is silent, and he is in awe of gods and ghosts, which is a good thing, but depending on the occasion, you can imagine that if you take Su Xiu to the Golden Palace, face the civil and military officials, and say that it is the fire set by the black impermanence, you have all wronged Zhu Youxiao, this child, how do you think His Majesty the Emperor will feel?"

As soon as Li Mi said this, it was like a basin of ice water poured on his head, and Zhu Changluo also woke up instantly.

He also really feels sorry for his son, and he has reached the point where he doesn't care about it, these things don't matter in private, a small place like the county government hall may be able to take it out and say it, but if you really want to get it to the court, who dares to talk about it, it's just something that a madman would do!

Zhu Yijun didn't like him very much as the prince, even after going through so many things, he still didn't feel at ease with him, if it weren't for Ye Xianggao's assistance, and the Zhan Mansion in the East Palace was full of talents, Zhu Yijun would not have worried about Zhu Changluo at all.

If he makes such a crazy thing because of Zhu Youxiao again, the impression that falls on Zhu Yijun's side will be even worse!

Zhu Changluo figured this out, immediately wilted, and said to Li Mi: "Sir, how should this be good, how can this eighth master be found?" ”

Li Mi came back to his senses from his contemplation and said to Zhu Changluo: "His Royal Highness the Crown Prince doesn't have to worry, we may not be able to find anyone, but we can find fire, as long as we find fire, we can find people!" ”

"Fire?" Zhu Changluo was also confused, and Su Xiu also questioned on the side: "The eighth master uses purgatory karmic fire, and it is not an extraordinary thing, where can I find it!" ”

However, Li Mi smiled and said nothing, looked at Xiang Mu and Shi Chongsheng, and then said to Su Xiu: "Are you sure you are seeing a blue flame?" ”

Su Xiu puffed up his chest and said to Li Mi: "Su Mou acts carefully and never lies, not to mention that the stakes are very important at this time, and Su Mou guarantees his life for every word he says!" ”

Seeing Su Xiu like this, Li Mi also nodded and said, "That's good." ”

Li Mi didn't care about these anymore, pulled Xiang Mu and Shi Chongsheng to the side, and asked in a low voice, "The second elder should know what kind of fuel can produce such a flame, right?" ”

Xiang Mu and Shi Chongsheng actually already had their own ideas, after all, they were instrument-makers, and they were often exposed to Li Mi's novel ideas, and gradually their superstitions such as black and white impermanence faded, but there was some meaning of "advocating science".

"If what Su Xiu said is right, it should be oil, but the smoke of ordinary oil is too big, and the flame can't be so pure, it must be refined oil!"

Li Mi nodded, squinted slightly, and hinted to the second elder: "There shouldn't be many people who can purify oil, right?" ”

Xiang Mu and Shi Chongsheng were also excited, and finally understood why Li Mi said that as long as they found the fire, they could find people!

In fact, Li Mi is not blindly confident, oil sounds very modern, but there have been records of exploitation in ancient China.

In the Northern Song Dynasty Shen Kuo's "Mengxi Writings", there is a description of oil, and it is called oil, which records in detail the process of oil exploitation and utilization by the people in the territory of Yan and Yan, and predicts that this thing will be popular in the world.

And the Ming Dynasty is not to mention.

Before the Ming Dynasty, there were four major inventions in China, and there were also four major inventions in the middle and late Ming Dynasty, that is, the discovery of oil, the invention and improvement of the flintlock pistol, and the treatment of smallpox.

As early as the Zhengde period, the Ming Dynasty had already built the first oil mine in Jiazhou, Sichuan, three hundred years earlier than the first oil well built by the Tsar, and the drilling and drilling technology for oil exploration and exploitation in later generations must have been the first invented by the Chinese, that is, the method and process, which are also recorded in detail in the Tiangong Kaiwu.

Since oil is no longer a rare thing, and even Xiang Mu and Shi Chongsheng know the wonderful use of oil, it shows that it is not impossible for someone to master petroleum technology in addition to the government.

However, it is one thing to master technology, but it is another thing to want to exploit it, salt, iron, carboniferous oil, etc., these are resources controlled by the government, and it is forbidden to obtain them.

What's more, although there is already a mining technology, after all, the means are primitive, the technology is relatively backward, it requires a lot of manpower and material resources, and the extracted oil is only the original use, which cannot be refined and derivative, so the value is not as great as imagined.

If it is mined by the private sector, it cannot be done without the support of the government, and even if it is mined, it will not be of much use.

Therefore, Li Mi temporarily deduced that the raw oil used by this person for purification should come from government channels!

Coupled with the fact that this person can enter and exit the palace and even climb the city tower, this conclusion is not impossible.

He was able to get Wei Zhongxian's support, so why did he work hard to pull up a huge team and spend a lot of resources just to dig up some oil and purify it and then set it on fire?

Therefore, as long as the official records are investigated and the flow of petroleum raw materials is tracked, it should be possible to screen out suspicious people and find a breakthrough again!

And oil is such a thing, but the Ordnance Bureau of the Ministry of Industry is controlling it, and it is the territory of Xiang Mu and Shi Chongsheng, so it seems that the truth is beckoning not far away!

Li Mi analyzed it like this, and Zhu Changluo was also very happy, after all, Zhu Youxiao had been locked up for three days, so he couldn't wait.

Zhu Changluo, Xiang Mu and others rushed back to the Ordnance Bureau in a hurry, mobilized all the scribes, and found all the scribes in the Zhan Mansion of the East Palace, and the mountains of files were moved out and began to be checked.

Li Mi also has a goal, only let everyone search the files related to the Salary Division, so that a lot of time will be saved!

It is not surprising that the charcoal fire used to heat the palace is sometimes used, let alone arouse suspicion.

Without this mysterious "black impermanence", without Su Xiu's detailed description of the flames, and without Li Mi's keen sense of detection and smell, no one would have been able to think of this clue and direction at all.

Now that we have a direction, it's easy.

Everyone didn't dare to blink their eyes, there was only the sound of whirring books in the room, and the old paper piles were full of moldy dust, not that someone suppressed the cough, Zhu Changluo was also very uncomfortable, but he couldn't help it, just stood outside the door and supervised.

Because he knew that with him standing at the door and staring, these people would not dare to steal at all, and they would be able to find out the clues faster!

Just as Zhu Changluo thought, these scribes and stickers quickly retrieved all the files related to the Salary Saving Division.

After all, oil is different from other resources, from the beginning of the imperial court in control, and later Li Mi founded the new camp of Shenji, in order to research and development needs, the official power of oil was handed over to the hands of the Ordnance Bureau.

Especially in the later period, the research and development of new firearms gradually took shape, and Xiang Mu and Shi Chongsheng also had a lot of experience in oil refining, and they controlled it even more strictly.

It is also enough to see the status of the Salary Division in the Ministry of Internal Affairs, and people say that the Salary Division is second only to the Yamen of Jinyiwei, and it is not deceitful, because the emperor's needs are always in the first place.

Therefore, the Salary Savings Division will use purified oil to ignite fires and so on, which also makes the records left by the Salary Savings Division in the Ordnance Bureau extremely complicated.

After the scribes sifted through these files, the rest of the work could only be done by Li Mi.

Because in their opinion, there is no problem with these files, and if they want to find out the clues, they can only be done by Li Mi, the mad dog Yushi, and the others have no trace at all.

Li Mi also has a headache, although he has done the countersignature of Dali Temple from the Institute of Reason, and then to the top of the Imperial History of the Zuodu of the Imperial Palace, copywriting work is no longer a problem, but Li Mi hates this kind of boring document proofreading work.

It's just that at the moment, he is helpless, in order to rescue the mysterious murderer who is suspected of being a black impermanence eighth master, Li Mi can only plunge into the pile of old papers, as for whether it can be effective, Li Mi does not dare to pat his chest, he can only say that he is doing his best!

However, what made Li Mi feel relieved was that this work did not cost Li Mi too much energy, because he quickly found the difference, not because he had a keen perception, nor because he was too lucky, but because of this person's name, frequency and timing of appearance, Li Mi couldn't help but pay attention!
