Cao Xuan touched the fire gun in his hand, and walked into Tongguan with Fa Zheng's people unhurriedly, and along the way, the eyes of Fa Zheng and others were paying attention to the thing in Cao Xing's hand the whole time.

A strategist like Fa Zheng is well-informed, but he also showed a strong interest in this thing in Cao Xing's hands, which is enough to show that this thing in Cao Xing's hands is very extraordinary, and even Fa Zheng once called it a treasure, because Fa Zheng saw the power of this kind of thing with his own eyes, and directly blew up the city wall of Tongguan.

Cao Xing looked at the inquisitive eyes of everyone, hehe, and the others smiled, and said to them that this kind of thing is called a fire gun.

This kind of thing, which began in the Yuan Dynasty and was best developed in the Ming Dynasty, can be said to be the first generation of metal tubular shooting firearms in ancient times, that is, the predecessor of the pistol in later generations.

This was originally an era of cold weapons, and it took more than a thousand years from the emergence of hot weapons in the market, and it was almost impossible to create hot weapons in this era, but Cao Xing had already made gunpowder out when he was running for the state pastor, and once gunpowder came out, this kind of hot weapon had the possibility of being born.

So at that time, Cao Xing thought of such a thing as a firecracker, but Cao Xing's body only had theory, no practice, this matter was naturally handed over to Ma Jun to do, when Ma Jun saw this kind of thing, obviously he was also very curious, Cao Xing directly told him a series of principles about firecrackers, mainly through the piston to propulsion, although Ma Jun was stunned at that time, but with his ingenuity, in a new research for a whole year, finally developed this kind of thing.

Although this is only the first generation of firecrackers, whether it is range or power, it is definitely not as good as the hot weapons in the future, but then again, through the joint efforts of Cao He and Ma Jun, this kind of thing has been perfected a lot, and Cao Xuan believes that it has been greatly improved at least compared to when the firecrackers first appeared in history.

In ancient times, the steelmaking industry was actually very developed, and solid ecological steelmaking technology had appeared in the Spring and Autumn Period, and in the founding period of the People's Republic of China, there was decarburization steelmaking technology, and in the Three Kingdoms period, there was a hundred steelmaking technology.

It is rumored that the reason why they are famous all over the world is because their whole body is made of steel, so they can blow short hair and sharpen iron like clay. And most of the weapons of that era were made of bronze or iron, so the weapons that could be made of steel were naturally very luxurious, both hard and tough, much higher than contemporary weapons.

When Luoyang was first built, Cao Xing arranged a large number of steel-making mills, coal smelters, etc. in Luoyang, moved all the industries of later generations, and gave Ma Jun sufficient funds, there was only one purpose, to make Ma Jun rest assured of steelmaking, he Cao Xing wanted the best steel in contemporary times, all equipped with such things as firearms, so when the gunpowder was launched, there would be no explosions and other phenomena.

Then Cao Xing went through a series of transformations, anyway, the range of the firearm in his hand now is about forty or fifty steps, which is about the same as the crossbow machine in his hand, but the power has increased a lot, after all, the spherical bullet is full of gunpowder.

As for the thing that gives Tongguan a fatal blow, it is called an explosives bag, and the explosives bag is much simpler, take a sack full of explosives, and then take a lead to directly detonate the explosives, as long as the amount of explosives is enough, a Tongguan is nothing, and a city can be blown up.

After Fa Zheng and the others listened to Cao Xing's narration, they were all amazed. It can only be said that this kind of thing is really amazing, but Cao Xing is laughing, and the magical thing is still to come in the future.

In this way, Cao Xuan led people into Tongguan, and Chen Hu also rode a horse with people, and pulled the dying Li Wei over, Li Wei had to kneel in front of Cao Xing at this moment, it was crying bitterly, and there was only one request, that is, I hoped that Cao Xing could spare his life.

However, Cao Xing smiled at him, and just said: "I will spare your life, what do you do to me!" ”

Hearing this, Li Dao was completely dumbfounded, and his eyes were already filled with endless despair.

It didn't take long for Cao Xing to publicly kill Li Dao, and then he was sued to the world, so Cao Xing's reputation has also reached a new level, after all, Li Dao is full of evil and tyrannical expropriation, and he has long been hated by people all over the world. Today, Cao Xing gets rid of this wicked person, and his reputation will naturally increase day by day.

After killing Li Wei, Cao Xuan and the others should go to Chang'an, Chang'an has now lost their last defense, so it is effortless to say that Cao Xuan occupies Chang'an. So far, Cao Xing has already included Si Li, except for the Chaoge generation, all of them under his rule.

Cao Xing's territory became bigger again, and his reputation spread all over the world, especially the fire guns and explosives bags used by Cao Xing in this battle, which amazed people all over the world.

However, not long after Cao Xing occupied Chang'an, new troubles reappeared, and Chang'an Road continued to go west, that is, into Hanzhong, which can also be described as a very large city, and is the gateway to the territory.

However, it is because Cao Xing has been advancing all the way, so it has aroused the vigilance of many people, and Zhang Lu, the Taishou of Hanzhong, was the first to line up with Chen soldiers and made a series of defensive preparations for Cao Xing, which can be said to be impermeable for Cao Xing.

If it is said that Cao Xing and Zhang Lu have become neighbors now, and Zhang Lu is on guard against Cao Xing, then forget it, but the key is that there are still two people who want to jump out and do something, and the two of them are Liu Yan in Yizhou and Han Sui in Liangzhou.

Liu Yan of Yizhou is also the current King of Shu, although he does not appear many times in the Romance of the Three Kingdoms, and he seems to be an unknown person, but if it is placed in political history, this Liu Yan can also be said to be a generation of heroes, and the abolition of Shi Limu was proposed by him.

It was his suggestion that aggravated the demise of the Eastern Han Dynasty and deepened the division of the major princes.

Liu Yan occupied the part of Yizhou, although Yizhou is not populated, but the land is vast and sparsely populated, the land is fertile, easy to defend and difficult to attack, and it is difficult for ordinary people to break in. Therefore, Yizhou, which is far away from the war, has also developed very rapidly in recent years.

Although Liu Yan just wants to be a king of Shu in peace, but the overall situation of his youth is still there, he knows that he can't allow others to sleep soundly in the couch, if Cao Xing further lays down Hanzhong, then the next step will threaten his territory, so he also began to support Zhang Lu openly and secretly, and even let Zhang Lu continue to send troops to attack Cao Xing, so it caused a certain amount of harassment to Cao Xing's boundary.

As for Han Sui, who is now the king of Liangzhou, it is also not a fuel-efficient lamp, although he used to have a cooperation with Cao Xing, and now there is still a deep trade between Qin and Liang, after all, the two places are too close, but it is because of this proximity that Han Sui is uneasy, Han Sui was born in Liangzhou, and he also wants to cut off Liangzhou, so that Liangzhou is firmly in his own hands.

Therefore, he naturally rejected Cao Xing and continued to expand his territory there, but his sworn brother Ma Teng, who is now King Yong, has a very friendly attitude towards Cao Xing, which makes him feel deeply uneasy, so it is reasonable for him to be more wary of Cao Xing.

Whether it was Han Sui or Liu Yan, they all adopted a method, that is, to use Zhang Lu in front of them as a shield, so that Zhang Lu could find ways to prevent Cao Xing for them.

Although Zhang Lu has only one Hanzhong and there are not many soldiers and horses, Zhang Lu has established his own sect in Hanzhong, called Wudou Mijiao, anyway, there are still quite a lot of people who believe in this sect.

This is a bit like the original Golden Rebellion, Zhang Jiao used to be an authentic common man, but because he established the Yellow Turban Sect, there were many people who responded to him, and many people believed in him, willing to die for him, including Zhou Cang before, and now Zhang Lu seems to have done this.

Under his call, the people of Hanzhong seemed to be very repulsive to Cao Xing, and even a few times the patrol team on the border of Cao Xing passed by a farmland, looking for Lao Long to escape a few bowls of water to drink, and even the one who paid for it, but after the patrol troops drank Lao Long's water, they were immediately poisoned, and in the end only two escaped back, but they were all dying.

For this situation, Cao Xing was naturally very angry, he wanted to send troops to attack, but was stopped by Fa Zheng, Fa Zheng just explained a problem to Cao Xing, that is, most of the people in Hanzhong are like Zhang Lu, so Zhang Lu seems to have become the emperor of the soil in that place, he has achieved the point that all the grass and trees are soldiers, if Cao Xuan really sends troops to attack.

It will only deepen the grievances of the people of Hanzhong against Cao Xing, and even if Cao Xing knocks down Hanzhong, it will be very difficult to manage.

Hearing this, Cao Xing gradually calmed down, and he began to think about what was going on in Hanzhong in history.

After Cao Cao unified the north, he was ready to go west to clean up Liu Bei, Liu Bei occupied Yizhou at that time, Hanzhong was the gateway to Shu, Cao Cao first occupied Hanzhong, and then Hanzhong was robbed by Liu Bei, Hanzhong at that time did not seem to have such a strong resistance, Cao Xing sent Jinyi Wei deep into Hanzhong to understand the people's feelings, and finally came to a conclusion.

Zhang Lu's set of five-bucket rice religion certainly made the local people believe in it, but the economic strength of Hanzhong is not strong, and the living standards of the people, that is, the general level in the late Eastern Han Dynasty, have not reached a high level.

Therefore, Cao Xing finally thought of a way, that is, to open public opinion, not long after, the newspaper this kind of thing came out completely, every day in the newspaper will always publish many world news, on the one hand, it can enrich the spiritual entertainment of the people, on the other hand, this is also a way to make money, more importantly, Cao Xing can also publicize his series of policies to benefit the people, so that more people can understand what kind of person Cao Xing is.

Therefore, Cao Xing temporarily gave up the military operation against Hanzhong, and after completing a series of deployments in Chang'an, he directly returned to Luoyang with people.

Cao Xing's attack on Chang'an reached Lower Chang'an and completed a series of actions that lasted for three months, but in these three months, the world has also undergone great changes.

Since the major princes have been crowned kings, the world has once again fallen into a beacon fire.

First of all, Lu Bu fired the first shot of this battle, at this moment Lu Bu is entrenched in Xuzhou, with Chen Gong as a military advisor, now Lu Bu's temper seems to have converged a lot, after all, after the tribulations of the world, he has also matured a lot, knowing that this world can not only be ruled with fists, so he also began a series of studies.

Of course, the reason why Lu Bu has this series of changes is not only because of the arrival of Chen Gong, but more importantly, Cao Xing is still in contact with Lu Bu.

In the original battle of Chaoge, Cao Xuan could see at a glance that Cao Cao was separating him and Lu Bu, but Cao Xuan chose to plan it.

First of all, Cao Xing clearly knows one thing, with Lu Bu's arrogance, it is impossible to stay under his hands, and it seems to be a good thing that Lu Bu is gone, and the reason why Lu Bu went to Xuzhou is also Cao Xing's advice to Lu Bu.

During these times, Cao Xing also used letters to constantly warn Lu Bu to study more in order to make himself stronger, Lu Bu was unmoved at first, but later began to gradually accept this series of things.

Now Lu Bu occupies Xuzhou, and it can be regarded as having its own base, but there are some subtle changes within them, that is, Lu Bu accepted Liu Bei, appointed Liu Bei as Xiaopei Taishou, and returned Liu Bei's wife, but Lu Bu, who has read the book, also knows one thing deeply, Liu Bei is too tolerant of this kind of person, he robbed Liu Bei's things, Liu Bei can still show that he doesn't care, this kind of person must be guarded against, so Lu Bu has always distrusted Liu Bei.

Liu Bei also seemed to realize that he stayed here in Lu Bu and had no chance of coming out in his life, so on a dark and windy night in a certain month, Liu Bei wanted to open the gate of Xiaopei and welcome some people out, but he was recognized by Chen Gong, and finally Liu Bei was defeated and fled.

This time Liu Bei fled to the direction of Yuzhou, Yuzhou is now guarded by Cao Cao's general Xiahou Yuan, the reason why he opened Xiaopei's city gate is also to welcome Xiahou Yuan, but now things have not been done, so he can only come here in disgrace.

Xiahou Yuan didn't dare to make decisions about Liu Bei's arrival, so he could only report the matter to Cao Cao, Cao Cao's attitude didn't know whether it was okay or not, anyway, Liu Bei also had some fame in the world, and now he was desperate to defect to him Cao Cao, if Cao Cao didn't accept Liu Bei, he would be laughed at by people all over the world, so it was better to accept Liu Bei for the time being.
