In the eyes of those big people who covet the highest power, some things are too small, but no one knows how much of a role these small things can play.

Luo Xixiao is not a small person, as Li Linfu's former confidant, the ranking is still above Ji Wen, Luo Tong, is a well-known title in the capital, especially for those officials.

Although his fame is not as great as that of Zhou Xing and Lai Junchen in the previous dynasty, the role he plays is not inferior at all.

Such a cool official actually has a day in prison, but unfortunately there are no firecrackers at this time, otherwise it will definitely set off a buying boom in Chang'an City.

Firecrackers were invented by the Chinese people, there is no doubt about this, the basis of firecrackers is black powder, how it was discovered, later historians still have debates, but it is roughly impossible to get out of the Tang Dynasty, the Five Dynasties this period, the reason is very simple, the Tang Dynasty worshiped Taoism, Taoist priests in the history of China, played a role not only for the ruling class to calm the internal contradictions of the loose religion, but also many other roles, such as doctors, politicians, tourists, and the most important one.

Chemist.

Legend has it that black powder was the first to be discovered in the process of refining the elixir.

Li Bai is just a rookie Taoist who has just entered the Tao for less than two years, and his Taoist age is not as long as Li Tengkong, and his cultivation is estimated to be not as deep as the latter except for fighting, but Liu Ji doesn't care, what he values is not the other party's preaching ability, but others.

"Brimstone...... Nitrate? ”

The former is easy to explain, it is a light yellow powder with a special taste, which will not be unfamiliar to any Taoist priest, and the latter, which is also recorded in Taoist classics, Li Bai's memory is very good, and he directly memorized those records.

"Someone got a kind of thing first, its color is similar to Pu Ni, such as holding snow without ice, strong burning, purple and green smoke, still ash, keep boiling, such as Pu Ni, the cloud is real saltpeter."

This record comes from a strange person named Tao Hongjing, he was a great alchemist in the Northern and Southern Dynasties, the so-called alchemy, in fact, is the early biopharmaceutical and chemical experiments, but what can be obtained in the end, there is no quantitative basis, but for a Taoist priest, this is a sacred cause, related to the art of immortality, but also Liu Ji fooled him, the biggest reliance.

Because, with the efforts of the Taoist priests, it has been infinitely close to the production of black powder, and in a few decades at most, it will appear in the Taoist classics, then it is very likely that the finished product has appeared, but no one realizes what that means.

He needs this epoch-making product, as a soldier, or a special soldier, he has been exposed to countless types of gunpowder, but most of them require a complex chemical system, which is precisely the field he is not good at, it doesn't matter, step by step, Liu Ji believes that one day, a scientific and rigorous system will be born in his own hands.

Because he has insights from thousands of years later.

Fortunately, in this era, Taoist priest is a decent and promising profession, at least Li Bai has changed from half-believing to being suspicious, and Liu Ji directly pointed out the direction and location for him.

"Qinghai?"

"Qinghai, originally belonged to the Tubo people, now, is my Tang Dynasty under the rule of Lintao County, outside the city ten miles there is a mountain name, the mountain produces sulfur, saltpeter, will be quarried, milled into powder, mixed with charcoal, there is gunpowder smoke, the smell is heavy and pungent, not approachable, will damage the limbs, hair and skin."

Li Bai raised his head and thought about it, and said uncertainly: "You know everything, what else do you want to do?" ”

Buddy didn't have time to look for it, Liu Ji said earnestly: "I have the responsibility of the imperial court, it is difficult to stay away, I heard that Mr. has always liked to travel, although Qinghai is far away, it is also the land of my Tang Dynasty, don't you want to go to see it, write poems to remember?" ”

By the way, find out where these things are buried, whether they are good or not, of course, this kind of extraneous meaning, he believes that such a smart person as Li Bai will be able to hear it.

Sure enough, Li Bai's face was already a little moved, and Liu Ji hurriedly struck while the iron was hot.

"This is a matter of privately asking Mr. as a reward, and there is another entanglement of money, and I hope you don't shirk it."

Li Bai's eyes lit up, but his mouth said: "If you really want to go, how can you break the bank." ”

"Yes, Gao Shi, the secretary of the King of Geshu County, the new Lintao Taishou, Mr. recognizes him."

"Thirty-five Lang, is he an official there?"

"Exactly, my father is on an errand in the Ministry of Culture, and he came down a few days ago, I'm afraid he will take office next spring, if Mr. is interested, he might as well go with him."

As soon as Li Bai heard this, he immediately made a decision, it was a good excuse to go with his friends, and in his heart, out of Longyou is Qinghai, which is not far from Guanzhong.

Seeing that he agreed, Liu Ji breathed a sigh of relief, in this era, if you want to find a geological expert, there is still only one choice, Taoist priests, only they have both leisure and corresponding knowledge.

fooled Shixian to find a mine for himself, Liu Ji felt that this was the biggest achievement since the crossing.

Although there are still white flags hanging in the house, Li Linfu's funeral has long been over, and the coffin is also buried on the side of the emperor's mausoleum under the gift of the Son of Heaven, and he did not return to his hometown and enter the earth as he wished.

Today's Prime Minister's Mansion has become the county government's mansion, his eldest son Li Xiu, demoted to attack the county prince of Guangling, several of the former sons, and some idle officials, and the eldest son-in-law Zhang Boji, because of this trip to Tubo, was directly promoted to the Ministry of Rites, and will preside over the New Year's Day ceremony in the coming year, which can be described as full of spirit.

Who knows, just a few months later, things will take an unexpected turn.

"Rohi was impeached? When was this. ”

"The day before yesterday, I heard that the Son of Heaven ordered to take people on the spot, but this time, I'm afraid that I have already locked it into Beijing."

Zhang Boji said worriedly, and Li Xiu glanced at him: "Do you have anything to do with him?" ”

"It's not just a certain family, but also a father-in-law."

"Are you worried that they are dancing the sword in Xiang Zhuang, and they mean to be Pei Gong?"

"Zheng Ang is a dog raised by Dr. Yang, Dr. Yang has always been at odds with our house, he suddenly made a difficulty, did he just want to pull out a certain family?"

Li Xiu looked at him silently, and what he remembered in his heart was his father's words before he died, he thought it was just a worry, but it turned out to be effective so quickly.

"If Yang Guozhong still doesn't give up, a certain family enters the palace to ask for the supreme, Boji, you think about it carefully, decide early, don't wait until the prisoner car enters Beijing, it will be too late."

Zhang Boji's hands and feet were cold for a while, Li Xiu's words made it clear that he would not be in this troubled water, but if the officials didn't do it, then what was the purpose of so much hard work?

How he was willing to give.
