After Zhang Huan ascended the throne, Jincheng County officially restored its original name Lanzhou, which has always been Zhang Huan's Longyou Jiedu Mansion is located, all the government affairs organs and a large number of weapons workshops are concentrated here, the Longyou Firearms Division specializing in gunpowder is located in a school field in the southeast of the city, which has a two-story wooden structure building.

But at this time, the Longyou Firearms Division has all moved to Chang'an, and the Longyou Firearms Division is only left with an empty building, as well as many facilities for gunpowder testing in the school field, and even the guards are gone, and the entire gunpowder test site is in a state of abandonment, and many children who live nearby always like to come here to play, take a look at this former heavily guarded place, and no outsiders are allowed to enter the mysterious place.

In the past few days, there are always a few strange Turks in the abandoned gunpowder test site, according to what they told the people around them, they are merchants in the Western Regions, and they want to buy this vacant land for storage, and if they want to buy land, they naturally have to investigate first, so these Turks have investigated the gunpowder test site very carefully, where to build warehouses, where to use horse roads, and so on.

Naturally, these Turks are the mysterious disappearance of the Hui State Master Surman and others, after the whereabouts were exposed, the entire Tang Dynasty was full of pictures of the capture of Turan, although the woman on the picture was a little too good-looking, and the reality of Turan was completely different, but out of caution, Surman still let Turan and most of the people temporarily return to China to avoid the limelight, and he himself disappeared in Bashan Shushui.

has been silent for nearly a month, as the capture pictures on the city gate gradually yellowed and fell off, the news of the capture of the Hui spies passed, but Suhrman still maintained enough patience, until more than two months, he began to consider the second task, stealing the formula of the Tang Lei, the Tang Lei is the name of the big cannibal, because the big food has been hit the Greek fire, so in the face of the enemy's mysterious weapons, there is always a sense of fear, and with the battle of Anxi, some of the escaped big food soldiers exaggerated the horror of the Tang Lei. This made the Great Food Caliph even more afraid, so in the terms of the peace talks between the Great Food and the Hui Hui, the first condition was to ask the Hui to get the recipe of the Great Tang Lei no matter what.

Sulman arrived in Lanzhou two hours ago, and before that, he had ordered his subordinates to set up suspicious formations in the Luoyang and Jianghuai areas, and successfully attracted the attention of the Tang Guoan Division. Now he had to get the recipe for Da Tang Lei in three days.

"Master, please come here."

Surman's eldest apprentice, Atru, beckoned to his master from afar, and he had been leading the survey of this abandoned gunpowder test site these days, and he wanted to show off his results to his master.

Sulman had always been dressed in a black robe, and his face was covered with a black veil, so that his expression could not be seen, and he rarely appeared in public, hiding most of the time in the carriage, and when he heard his apprentice calling him, he walked slowly over. It was a scaled-down wooden hut that could be drilled into with a bent down, and Sulman got into it. I saw that the hut was in shambles, and there were traces left by the explosion test everywhere.

"Master, I've been looking for a few days, only there are traces of the Great Tang Thunder in this hut." Atru said as he looked at his master, his eyes revealing a hint of longing to be praised.

Atru was the eldest son of King Qarluq, and unlike Turan, he was sent to Dashi as a hostage since he was a child, but he didn't know how. Ten years ago, he actually fell into the hands of Sulman, and became Surman's apprentice with a group of princes and princesses from small countries in the Western Regions, but soon, except for him, all the princes and princesses were sent back to Baghdad.

He was the oldest. Therefore, he became a great apprentice. Since he was a child, he felt that Shizun was an extremely mysterious person. His whereabouts are uncertain. It's rare to see him once a year. Shizun never taught him anything. He didn't even know if Shizun knew martial arts. He didn't know anything about the master. Nevertheless. Atru was still terribly afraid of the young man in black. He was able to take all the hostages of the nations in Baghdad. He was also one of the highest elders of the Manichaean land. Now he has become a national teacher of the Hui country.

Atru sensible earlier. He had a vague feeling. The true identity of oneself as a master is by no means so simple.

Sulman entered the house and took off the black veil. His pale, bloodless face was revealed. He quietly scrutinized everything in the room. The wooden walls are inlaid with broken porcelain tiles everywhere. Apparently left after the explosion of the porcelain vase. He saw a black spot on the roof. Then he moved to a small table next to him. Stand on it and reach out to wipe the black stains. Atru next to him suddenly breathed a sigh of relief. Shizun doesn't seem to know martial arts.

Sulman wiped a handful of black stains. There was some black ground powder in my hands. He twisted it. I put it in front of my nose and sniffed it. This is charcoal powder. In other words, there are charcoal ingredients in the Datang Thunder Ground formula.

Then. He saw that there was still a black mark in the corner of the house. It's a little different from what he sees now. He climbed down the table again. He bent down and wiped a little black stain on the corner of the wall. The black stain also has a little powder. He put it in front of his nose and sniffed it again. Now he seemed to smell something familiar. He frowned and sniffed again. It is indeed the smell of fire oil. Yes. He's sure. He was all too familiar with the substance.

"Could it be that Tang Lei is also the same as Greek fire. Is it all using the power of fire and oil? ”

Suddenly, Sulman took a step back, stared at the corner of the room, and whispered, "Who is it, come out!" ”

Atru was also frightened and jumped back, and suddenly pulled out the long sword at his waist, only to see a wooden board in the corner of the house slowly lifted, revealing a round black head, and then two boys, one seven or eight years old, and the other five or six years old, came out of the big hole in the dog's hole, they looked at Sulman and laughed, "Surprise you!" The younger boy clapped his hands and laughed.

"Kill them!" Atru clenched the hilt of his sword, and his eyes showed murderous intent, and two children came in under his eyelids, and he didn't even notice it, which was a great shame.

"Don't be impulsive." Sulman glared at him, and suddenly he crouched down and asked the two children with a smile, "Do you all live nearby?" ”

Atru's heart sank suddenly, he never knew that Shizun could speak Chinese fluently.

The two children glanced at each other and nodded in unison, Sulman took out a dozen copper coins and put them on the table, still smiling and said, "Answer me a question and give you a penny, are you willing?" ”

A dozen copper coins were polished yellow and shiny by Sulman, and the two little boys nodded heavily.

"Then let me ask you the first question, did your father or uncle or neighbor work in this before?"

"Yes!" The little boy was the first to raise his hand. "My uncle used to work here, earning two dollars a day."

"Well said, your uncle is very capable." Sulman became an amiable uncle, and he took a copper coin and gave it to the little boy, "And what is your uncle doing here?" ”

"He's specialized in carrying things." The little boy was a little frustrated.

"It's not bad to move things!" Sulman gave him another copper coin, turned back to the older boy, and asked, "What about you?" Do you want to make some money. ”

"Jiro. Let's go! The older boy sensed the strangeness of the strange uncle's smile, and he quickly pulled his companion, and the two ran away, Suhrman staring at their backs and smiling grimly.

"You bring me the uncle who carried things at night, and slaughter these two little cubs for me by the way."

At night, the bright moonlight covered the city of Lanzhou, and in a house in the north of the city, Atru hurried to a house with no lamp. He said respectfully: "Master, we have already tortured him. ”

"Come in!"

Atru dodged into the house, and it was dark. Only on the side of the window was a patch of moonlight, and Sulman lay under the moonlight, staring at the silver-white moon, with a black robe and a snow-white face, as if he were a creature that had absorbed the essence of the moonlight.

"What did he say of value?"

Atru bowed and said: "He has several carriages, which were requisitioned by the government and were responsible for carrying materials, and he said that all the things were packed and stored in the Longyou government office, and most of them had been shipped to Chang'an. There is also a part of the box that is still stored in the warehouse of the Longyou Government Office. ”

"What is Tang Lei?"

"He didn't know either, the defense was so tightly guarded that they only heard loud noises and black smoke rising from the ground often, and nothing else."

"What else? Do you want me to ask, and you only say one word? Sulman turned his head slowly, his gaze unusually cold.

Atru's heart trembled, and he hurriedly said: "All the craftsmen have been brought to Chang'an, and the Longyou Government is also rearranging the items. In these two days, they will all be transported to Chang'an. ”

Speaking of this, Atru hurriedly added: "This person will also be a porter."

The room was quiet, Sulman fell into deep thought, when he stole the secret of the Greek land of fire, only two of the five hundred people he brought with him escaped in the end, he jumped into the sea to escape, he knew very well what this kind of secret meant to a big country, once the secret of Tang Lei entered Beijing, he could not have any chance.

"We'll go now!" Sullman made the decision without hesitation.

Longyou Government Office. That is, Zhang Huan's group of staff. Hu Yong, Du Mei, Pei Mingyuan and others were in charge of Longyou and various places under actual control, which was originally called Longyou Government Affairs Yuan. With Zhang Huan ascended the throne, Hu Yong and others have entered Beijing as officials, this office that was just built a few years ago was deserted, and the Longyou Jiedu Mansion has moved to Shanzhou in Hehuang, this large-scale building complex has lost its aura of power, Zhang Huan has made instructions not long ago, and it will soon be changed to the Longyou Branch of Guozijian.

At present, the government government is in the transition period, the government is very messy, all kinds of documents accumulated over the past few years are piled up, dozens of officials are responsible for screening all kinds of materials every day, useful classification and boxing, useless ones are burned one by one, this work has been carried out for nearly two months, and it is gradually coming to an end.

Lanzhou City is different from Chang'an, there is no neatly planned square here, there is no square wall, residential areas and commercial areas are mixed together, it seems a little messy, in the dead of night, occasionally you can see some people who like to travel at night.

Lanzhou has completed its historical mission, has been restored from the political and economic center of a local government into an ordinary frontier state, the major military camps in the city appear empty, most of the troops are stationed in Guanzhong, Lanzhou's garrison is not much, now there are only 2,000 people left, mainly stationed along the Yellow River, there is almost no garrison in the city, the daily security is in charge of the Wuquan County officials, but only the government government has a garrison of 500 people. Their task was to escort the last batch of materials back to Chang'an.

The sky has begun to appear dark clouds, the moon appears and disappears in the dark clouds, and the earth is also bright and dark, which seems a little weird. Five black shadows quietly appeared in the woods of the Longyou Government Office, Atru crouched on a tree, carefully inspected the garrison here, not far behind him, Sulman covered his whole body in a black robe, tall figure, like a strange dark warlock, he covered his face with a black veil, no one knew what he was thinking or seeing.

The entrance to the warehouse was about fifty paces away from them. Three teams of 20 Tang soldiers were constantly patrolling alternately, and I don't know if there was a hidden sentry.

"Atru, go!" An irresistible voice came from behind Sulman's black veil. Cold and lifeless.

Atru felt that he was a manipulated puppet, and he couldn't have a little idea of his own, he didn't even know the words of Datang, so how could he find the things he wanted, but he didn't dare to say a word, jumped off the tree, waved his hand, and led his three companions to fly towards the entrance of the warehouse a hundred steps away.

Surman was the only one left in the woods, and he watched coldly as the Great Apprentice vanished. Suddenly, like a mutated demon, he actually flipped a heel fight in the air, like shooting a powerful arrow, and his slender body shot straight away.

Atru and the others had already climbed into the warehouse through an air window, and several people stood on the spot, all a little at a loss, the warehouse was tall and wide, and it was dark inside. There were no lights, but as their eyes got used to it, they saw something that was jaw-dropping.

I saw countless large boxes piled up like a few hills, at least thousands, and many boxes were buried deep inside, and they couldn't be seen outside, to find the Datang Lei formula they wanted in these thousands of general-looking boxes, or even just a line of text, it was tantamount to looking for a needle in a haystack. What's worse is that several of them don't understand the Tang script at all. Several people looked at each other, not knowing where to start.

"Come here! Move this out of the way. ”

Sulman's ghostly black robe suddenly appeared above their heads. I don't know when he came, a few people were stunned for a moment, and immediately ran over, only to see their national teacher pointing to a box and saying, "This is it, move them." ”

Several people carefully moved the boxes open, which contained books or documents, which were very heavy, and each box had a white note pasted on it, and they only knew one fire character, but there was no box in front of them.

"Move out of the way here, too."

I don't know how long it will take, Shizun has reached another box mountain a hundred paces away, but he is obviously above him, and Atru is as if he has seen a ghost, and his heart is terrified.

"And move out of the way here!"

"It's the same here."

For a whole hour, the four of them were moving the box, nearly four o'clock, they were exhausted, at this time, Suerman had disappeared, he drilled down from the cracks to find the box he needed, finally, he was also a little tired, leaning on the box to close his eyes and recuperate, he only had a hope of coming here to find the formula of Da Tang Lei, after all, this place is much looser than the guards in Chang'an, he only hopes that there will be a little omission in the process of transferring the documents, and the formula he needs will be left in a few words, but he has been looking for it almost overnight, he still didn't find the box he wanted for the firearms division.

Sulman sighed secretly, ten years ago, he used 50,000 taels of gold to buy off the guards, entered the secret room where the Greek fire recipe was placed, but touched the mechanism and almost died, is this time he also going to follow the same old path?

The key is that he understands the organs of Byzantium, but he doesn't know anything about the organs of the Tang Dynasty, the mysterious ingenuity of the ancient country of the East is far more than that of Byzantium, Suhrman was just about to stand up, but he felt that his robe was hooked by the nails of the box behind him, he turned around and carefully removed the robe from the nails, suddenly his eyes were straight, and on the box behind him, there were three words clearly written on the firearms division, although the light was dim, he could see it clearly, yes, it was it!

There was nowhere to find the iron shoes, and it took no effort to get them, and Sulman remembered this ancient oriental proverb, and he couldn't help but be surprised and delighted. But he did not rush to make a move, but carefully examined the boxes around him, there were only three boxes in total, and he looked up at the sky through the air window, the moonlight was bright, and the night was deep. After this darkest hour, the sky should be bright.

Sulman took out a glittering dagger from his arms, and with a slight stroke, the wooden strips of the box were cut off by three pieces, and he quickly removed the plank from the side, and the contents of the box were all ledgers at a glance, and Sulman took out a copy casually. I hurriedly browsed a few pages in the faint moonlight, which seemed to be paid for labor, and three carriages were used on a certain day in a certain month. Pay five times

He threw away the account book in his hand, and pulled out a more old one, Suerman's heart suddenly thumped, this is an account book for the purchase of various materials, he saw at a glance the purchase of charcoal on May 7 300 catties, charcoal, he remembered the charcoal powder he touched in the hut, it should be it, but Suerman was still very cautious. He went out again to find the book of labor expenses just now, and in the page of May 7, he found one of them, 300 catties of charcoal, and 50 pounds of powder.

Charcoal powder, which is indeed one of the ingredients of Datang Lei, with the first harvest, Suerman was in good spirits, and he opened another box, which was full of letters. He didn't have time to look at the fiefdom carefully, only glanced at the letter cover, and kept turning over more than two hundred letters, and suddenly, he was attracted by a letter, which seemed to be a letter written by the Firearms Department to the combat military, and the letter cover read: A few explanations for the improvement of the power of the earth-shaking thunder, and there are two words below it, Suerman knows that the official documents of the Tang Dynasty have provisions for recording copies.

Shocking thunder. Sulman muttered to himself. "It turns out that the Tang Thunder is called the Heaven-Shaking Thunder."

He immediately tore open the letter impatiently and read it hastily: the reason for the weak explosive power of the military's reaction to the earth-shaking thunder three months ago had been ascertained. Guy used the oil for Dunhuang production, after three months from the Persian purchase of Persian oil 500 barrels, the obtained oil powder is pure, and the original formula in the charcoal powder reduced to two percent, salt reduced to one into five, yellow wax reduced to half percent, oil powder increased to sixty percent, and then added dry paint one or two, fixed powder one or two, so that the power of the new earthquake thunder is stronger than the old earthquake thunder more than three times

Reading this, Suerman was so excited that he almost roared, fire oil powder, charcoal powder, salt, yellow wax, dry lacquer, and fixed powder This is all the recipes of Datang Leidi.

However, he still restrained his inner agitation, and found the record of March last year from the purchase book, the first line was to purchase 500 barrels of Persian oil and pay 300 yuan.

That's it, Sulman trembled his hands, and when he carefully put the letter and the ledger into his arms, the sky was already a little light, he looked at the piles of documents again, sneered, took out the flint, click! Click! There were two sounds, and a blue flame appeared in his hand, and he lit the wooden box containing the letter, and in a moment, a wisp of black smoke came out.

"Master, what are you doing here?" Atru cried out in surprise.

"Nothing!" Sulman said expressionlessly: "Since I can't find what I want, I'll burn the traces with a fire, and we'll go to Chang'an again." ”

"But

Atru wanted to say that he could come back tonight, but he couldn't say a word because of Shizun's gloomy face.

"National teacher, someone is coming." One of his men screamed nervously when he heard hurried footsteps outside.

"Let's go." As soon as Sulman's words came out, four cold rays of light suddenly shot out of his hands, and suddenly sank into the chests of the four people, and the four of them screamed, their faces turned black in an instant, and they fell to the ground and died.

Sulman slowly walked over to Atrudi's corpse, kicked him, and sneered cruelly: "Don't blame the master for killing you, just blame you for knowing too much." ”

With that, he turned around, like an extremely dexterous ape, climbed the wall, and threw himself out of the window. With a bang, the door of the warehouse was kicked open. Walk the water! The anxious shouts of the soldiers were chaotic

Thick smoke billowed over the government office, the streets were full of people running to put out the fire, a carriage was lowered by the curtain, a miserable white face disappeared behind the curtain, the carriage accelerated, and left Lanzhou City silently.
