Copper represented wealth in the eyes of ordinary people in the Song Dynasty, but in the eyes of Lotte, copper is not as simple as money, because in Lotte's view, copper can play a greater role in money, that is, to make artillery.

Artillery was used as a weapon that changed the history of world wars, and it did not appear in the era of the Song Dynasty. Some people will say that in the Song Dynasty Renzong Dynasty ministers Zeng Gongliang and Ding Du spent five years compiling the "General Essentials of the Martial Arts", Song Renzong also wrote a preface to this book, and clearly recorded a total of more than a dozen different styles of cannons, including single cannons, double cannons, five-cannons, seven-cannons, tiger squat cannons, column belly cannons, whirlwind cannons, combined cannons, lying car cannons, car cannons, traveling artillery carts and so on.

After Lotte's careful study, the "cannon" recorded in the "Wujing General Essentials" is not the artillery of later generations, but the "stone bag" that fires stones, and it is also a catapult, because the "Wujing General Essentials" clearly writes that this kind of cannon is artificially dragged and fired, and it is not the real meaning of the artillery in later generations at all.

Lotte to silver for copper money, naturally has its own ideas, artillery belongs to large castings, in the Northern Song Dynasty, iron smelting technology is not mature enough, so the quality of cast iron is not easy to control, so iron can not be used to make artillery, and iron and copper are difficult to melt, the furnace temperature is more difficult to control, melted molten iron is easy to produce a large number of bubbles, will remain in the cooled cast iron open throwing holes, because of the existence of these pores, it is very easy to make the artillery explosive.

In the history of the later generations of the Braided Dynasty in the experience of a hundred years of national humiliation in China, there was a batch of self-made artillery, the explosion rate was as high as forty percent, because the smelting technology was not up to standard.

Copper has good ductility, not as brittle and not easy to rust as pig iron, the melting point of iron is much lower, and the fluidity of copper is much better than that of molten iron, so the porosity effect produced is much smaller, so it is most suitable to use copper to make artillery.

After controlling the silver mines in Dongying Shimane, Lotte had a large amount of silver to exchange for copper coins, and the silver flowing into the market filled the gap in the currency circulation of copper coins, and did not have any impact on the currency circulation of the Northern Song Dynasty.

The operation of the ticket number is normal, and the operation of the semicolons distributed in the various roads is also good, and the large amount of investment in the early stage has begun to return, and because of the turnover of the imperial court and various taxes, these semicolons have begun to make profits.

Money can make people's eyes open, and Le Hou Ye looked at the surplus data on paper, and his mood was obviously not ordinarily good.

When it came out of the Huapiao, the sun had already set in the west, emitting a golden-red light, and the whole Bian was shrouded in it.

As the so-called remnant sun is like blood, in this layer of almost blood-colored light, the killing machine appeared without warning.

In the private room of the restaurant opposite the Hua Piao, a thin crack suddenly flashed open in the wooden window, and several sharp arrows glowing with black blue light poked out, and the tips of the arrows pointed directly at Lotte's vital points.

As long as a little skin is detected, the toxin will flow into the body with the blood to make people's lives hang by a thread.

In ancient times, there were not a few people who died of arrow sores, for example, Emperor Taizong of this dynasty, Zhao Kuangyi, also died because of the arrows of the Khitan people, and the arrow sores attacked every year and finally died.

Seeing Lotte coming out, the driver who was parked on the side hurriedly drove over.

The archer who was ambushed in the opposite restaurant was very clear, and the carriage came to block Lotte's figure, and he could only wait for a few breaths in Lotte.

Approaching the late spring of March, Biandu is already full of flowers, and the weather has warmed up, but occasionally there will be a touch of cold wind blowing, which makes people feel like a spring breeze.

A gust of spring breeze passed, and Lotte, who was waiting for the car to come, felt a little chilly, goosebumps popped up inexplicably on the back of his neck, and even his hairs stood up, and he couldn't help shrinking his neck.

At this time, Lotte Ear can clearly hear several "boom" sounds coming into the ear, and then there are "whoosh" and "whoosh" sounds.

After staying in the northwest and Western Xia for nearly a year, and experiencing the battle on the battlefield, Lotte immediately felt bad, and could hear these two different sounds, which were the vibration of the bowstring and the sound of the arrow breaking through the air.

The speed of sound transmission is more than 300 meters per second, and the speed of arrows is more than 40 meters per second.

"Officials beware!" Wu Song reacted more quickly, and Wu Song, who was guarding Lotte's side, immediately blocked his body in front of Lotte.

A muffled snort came from Wu Song's mouth, and I saw that two arrows were inserted into Wu Song's back shoulder and leg respectively at the sound of breaking the air, and at the same time, Lotte's figure was also thrown to the ground by Wu Song.

While! While! While......

Several sounds sounded, only to see a number of arrows landed on the stone road where Lotte was standing, and then it was bounced high, and then several screams were exhaled, apparently innocent passers-by and the account man who sent Lotte from the ticket number had arrows......

Sudden changes sudden, before and after just a few breaths.

"Protect Master Hou!" The screams and arrows that fell to the ground made the guards who were guarding Lotte react, and they used their bodies to block Lotte and Wu Song who fell to the ground, and at the same time, Lotte's carriage also drove over, blocking between the restaurant and Lotte and Wu Song.

"The assassin is in the restaurant opposite, go and take it!"

The guards who reacted shouted one after another, picked up the guys on their waists and rushed towards the opposite restaurant one by one.

Since he resigned from his official position in the court that day, Lotte began to strengthen the guards around him, in addition to the imperial city guards assigned by Zhao Kai, some of the guards around Lotte were carefully selected by the army, and the salary was far beyond the past.

"How are you, officer?" Shakuchi and Tu Si also hurriedly asked around Lotte.

Falling to the ground, Lotte only felt a little pain in half of his body, and then looked at Wu Song, who was lying on top of him, his face turned blue at the moment, and his breathing became a little short, so he hurriedly sat up and helped Wu Song to sit up: "Wu Song, how are you?" ”

"No problem!" Wu Song shook his head and said, but his face became more and more pale, and then Wu Song called: "Shakuchi! ”

Shakuchi was just waiting in front of Lotte, and he really hadn't seen such a scene, and at this moment, he was also pale and sweaty on his forehead, and hurriedly asked, "What do you have to say from the military attaché!" ”

"The arrow is poisonous, dig out the arrow from me with a knife!" As Wu Song spoke, he took out the Uzi steel knife that Lotte had given him at his waist.

Shakuchi hurriedly waved his hand in fright: "The little one has never done this kind of work!" ”

Wu Song snorted and looked at Tu Si: "Tu Si, you come!" ”

"Little ......" Tu Si was frightened and waved his hand again and again.

"No waste!" Wu Song scolded hatefully, pulled out the steel knife with a choked right hand, and the arrow shot in the leg with his left hand fell.

His pants were cut open by a knife, and a muffled snort came out of Wu Song's mouth, and in the muffled snort, he saw Wu Song stabbing the tip of his arrow with the tip of his arrow, and then slashed it hard, only to see that the tip of the arrow was ripped off alive along with a piece of blood stained with black bruises.

Lotte stretched out his hand and said to Wu Song: "Give me the knife, and give me the shoulder arrow wound!" ”

Sweat as big as a bean fell from Wu Song's forehead, Wu Song nodded and handed the knife to Lotte, "Officials don't have to be soft-hearted, if officials are soft-hearted, Wu Song's life is gone!" ”

I can't be soft-hearted, Wu Song's life can't be soft-hearted, Wu Song is not wrong, Lotte gritted his teeth and concocted it according to the law, cut the shirt on Wu Song's back shoulder, and a piece of arrow was torn off with a piece of flesh and blood, and even when Lotte was under the knife, he could clearly hear the sound of the steel knife scraping on Wu Song's bones, which made Lotte's heart throb.

At the same time as another muffled snort, Wu Song's body tilted, and because of the severe pain, the whole person could no longer support it, and fell into Lotte's arms.

The arrow thrown into his hand, Lotte hugged Wu Song and shouted to Tu Si: "Tu Si, go and find His Royal Highness King Yun, and say that I ask His Royal Highness King Yun to send the best imperial doctor in the palace, the kind of imperial doctor who is good at treating arrow wounds and poisonous wounds." ”

"Yes!" Tu Si hurriedly answered, and ran in the direction of the inner city.

After staying in the army for nearly a year, Lotte looked at the arrow that was taken from Wu Song's body, and he could tell that the arrow was fed with poison, although a piece of meat was stripped off, there was still a little toxin that would flow into the body with the blood. Lotte was ruthless and began to suck Wu Song's wound with his mouth, trying to suck the toxins in Wu Song's body along with the blood.

The mutation was prominent, and at this moment, the people on the street were already in chaos and fled in all directions; The chaos in front of him immediately attracted the attention of the street patrolman, who immediately ran over and asked, "What happened?" ”

"There are assassins on the opposite floor who assassinated my lord!" Shakuchi said busily.

The sound of fighting between the guards and the assassins could be heard in the restaurant opposite, and the people who had dispersed on the street began to gather around the restaurant to watch.

Tokyo City is the Imperial City of the Great Song Dynasty, there are high-ranking officials and dignitaries everywhere, the street is patrolled by errands with blades from time to time, and the security is naturally far better than other cities, and since the founding of the Great Song Dynasty, there have been very few assassinations of high-ranking officials, and a group of street patrols were shocked when they heard this, and they recognized the young man in front of them, it was the Marquis Le who had once served as the Yin of Kaifeng Mansion did not dare to slack off, and hurriedly drew his blades and ran towards the building.

……

The sound of fighting on the opposite floor subsided, and after a while, a guard hurriedly ran in front of Lotte and said, "Master Hou, the three assassins on the opposite floor saw that there was no hope of breaking through, and they all swallowed poison and died!" ”

"Dead?" Lotte raised his eyebrows, and saw that the blood flowing from Wu Song's wound was bright red, and he was relieved, which showed that the toxins in Wu Song's body had been infiltrated by the arrow, so he continued to ask the guard, "Can you see the identity of these assassins?" ”

The guard replied: "Although those three assassins are wearing the costumes of my Great Song Dynasty, but after the hat on their heads is dropped, they have the hair of the party members, and they should be the remnants of the Western Xia Kingdom!" ”

"Hurry up and find Lang, send Wu Song back to the house for diagnosis and treatment!" Lotte said to Shakuseven, and ordered the guards around him: "Follow this official to the opposite restaurant to check!" ”

……

When Lotte entered this restaurant, the shopkeeper and his partner of the restaurant hurriedly greeted him, and bowed to Lotte tremblingly: "Master Hou, the little one is just a businessman who opens the door to beg for a living, and it really has nothing to do with the assassin who assassinated Master Hou......"

Ignoring the shopkeeper, Lotte walked directly to the second floor, and at the same time instructed the guards beside him: "Summoning the Imperial City Division and the official in charge of the punishment of Kaifeng Mansion and the official in charge of the assassin's body." ”

Lotte can't remember how many times he has been assassinated, but what makes Lotte angry is that this is the best Biandu in the Great Song Dynasty.
