It only took four days for Echeng to change the king's banner at the head of the city.

On the day of the fall of the city, Huang Zu set himself on fire in the Taishou Mansion - not that he was so strong that he wanted to die in the city, but understood that with his relationship with the Sun family, the matter would only be settled if he died.

Otherwise, the life of the Huang family in Nanjun will definitely be difficult in the future......

It was Huang Zu who was not optimistic that Liu Biao would be able to defend Nanjun, so he had to die in the city today.

After the fire of Taishou Mansion appeared, the defenders of Echeng surrendered more quickly, and soon Sun Ce completely occupied the urn city, began to collect prisoners, and at the same time entered the city, rushed directly into the fire, and brought out Huang Zu's unburned head!

……

"Gongjin, I'll leave it to you after that, and I'll be back in a month and a half." Sun Ce took a box and said to Zhou Yu.

"You can go with confidence, and you will also put a stick of incense on my uncle for me." Zhou Yu said.

After the capture of Chukou and Echeng, there will be no strong resistance to Xiling in the north, Yunmengze water system in the west, and Luo County on the north bank of the Miluo River in Changsha County in the south, that is, the east gate of Jingzhou in the south of Jiangxia and north of Changsha.

Now the Yunmengze water system is still very rich, it doesn't seem to have subsided for most of it in the future, it is still the lake group with a circumference of thousands of miles, the important ancient battlefield of the Three Kingdoms, Chibi, and it is also in the Yunmengze water system, if you go directly to the west from Jiangxia, you can only use the water army.

And to the north, it is to break through Xiling, which is a real tough battle.

As for the south......

The four counties of Jingnan are similar to the south of Jiangdong, the county seat is sparse and the mountain people are dense, especially the southernmost Wuling County and Lingling County, which are all barbarian rampant places.

Therefore, in history, from the end of the Eastern Han Dynasty to the beginning of the Three Kingdoms, the ownership of Jingnan has always been very arbitrary.

During the Three Kingdoms period, Jiangxia has always been the bridgehead of Eastern Wu, and the most elite Nanjun and Nanyang have always been under the control of the north.

As for the four counties of Jingnan...... After Liu Biao's death, Nanyang and Nanjun surrendered to Cao, Liu Bei and Liu Qi also easily obtained the annexation of the four southern counties, and when the Jiangdong people came, the four southern counties were persuaded by Lu Meng to surrender......

Especially Wuling County, in the southwest of Jingzhou, that is, next to the south of Yizhou - to be more precise, next to Nanzhong, the so-called Nanzhong Barbarian, Wuling Barbarian is just the name of the Han people, in fact, the barbarians in this area are connected into a piece, and there is no distinction between Nanzhong and Wuling.

Even during the negotiations between Wu and Shu, Wuling County was often ignored and only the other three counties were discussed.

Since the mobilization of troops in the four southern counties, it is basically because of the rebellion of the barbarians or the rebellion of the local forces in Jingnan, and it is rare for the two forces to fight for this place.

To a certain extent, it also shows that from Liu Biao to Sun Quan, they did not really control the four southern counties at all, and this situation was not really alleviated until the Eastern Jin Dynasty was dressed in the south.

Naturally, Zhou Yu has no intention of moving troops to the south now, and the situation in Jingnan is still waiting for Chen Gong's "tiger and wolf".

As for the north...... Unless the situation changes, Zhou Yu will also wait for the victory on the Huaihe battlefield to avoid the damage caused by the attack.

During the period when Sun Ce left, Zhou Yu only needed to recover the three counties of Shaxian, Xiapheasant, and Zhouling, and there was no difficulty, or even ...... All it takes is a letter of persuasion.

Anyway, after waiting for the battle situation on the North Road and the South Road, Sun Ce decided to take Huang Zu's head and go back to Jinling to report - of course, mainly to go back to Wu County to worship his father, but nominally to report on his work.

At the same time, only Ling Tong - Zi Gongji, that is, the first young general to rush into the city before, can be regarded as the first achievement.

Because Sun Ce is going to go to Wu County to worship in the future, someone must stay in Jinling, Zhou Yu is going to sit in Jiangxia at this time, Sun Ce brought Ling Tong, who made meritorious contributions, and he can also ask for merit for him.

……

At this time, the white map of Jinling had just received the news of the "appearance of the repeater" - it only took three days to send the news back to Jinling from Jiangxia, which was already the result of the construction of the signal tower.

Now that Jiangxia is also controlled by the General's Mansion along the river and in the south, the signal tower will also be laid, and it will definitely be faster in the future!

"Seven arrows in a row...... Cumbersome and need to be erected...... It can only be fired in bursts, and cannot be stopped...... Seventy paces at range......" Bai Tu looked at the repeater described in the letter.

When the military information was issued, Sun Ce had already seized a batch of physical objects, but the time for the physical goods to be sent back to Jinling was much slower than the news, and now Bai Tu could only see the description in the letter.

"Repeater...... Could it be the 'Zhuge Repeater'? Wolong has come out of the mountain? Bai Tu was a little worried.

After all, when it comes to the repeating crossbow of the Three Kingdoms period, the first thing that comes to mind must be the "Zhuge repeater".

What is the specific principle of Zhuge Repeater, Bai Tu does not know, because there is no reason that has been handed down, and the imitation of Zhuge Repeater in later generations is also strange.

Some can shoot multiple arrows in a row after pulling the trigger once, some shoot one arrow after pulling the trigger each time, some need to be wound multiple times, but they don't need to be loaded every time, and some even fire ten arrows in a row at once......

The result of using only a handmade wood and iron machine to imitate it is not ideal, especially since every time you pull the trigger, you can shoot an arrow, and you can put multiple arrows on a magazine change - this kind of imitation that theoretically seems to be the closest to a repeater, and you can only shoot cardboard from twenty meters away!

Twenty meters, changed to the measurement standard of the Han Dynasty, that is, thirteen or four steps.

Later, Ma Jun of Wei also improved the repeater and made a single soldier crossbow, which could be fired hand-held, but ...... In the later period, both Shu and Wei gave up the repeater, which shows that this thing is still very flawed.

It's just that in the world of Chengji, Bai Tu didn't dare to relax his vigilance, and cold weapons such as crossbows were originally within the scope of the Ministry of Industry's research.

However, only the specially appointed master craftsmen of Jingkou City are conducting research in this area, and Pang Tong is only responsible for "inspection".

After all, with Pang Tong's ability, there are still many things that only he can do, and Bai Tu is not ready to let him be distracted by "organ learning" anymore.

These will not be useless work, even after entering the age of firearms, the equipment of guns is indispensable as a basis!

And you must know that the time when guns became the rulers of the battlefield was actually much later than artillery, and artillery had become an element of the battlefield in the 17th century, which had more advantages than any catapult and heavy crossbow, and the performance of guns completely surpassed that of cold weapons, which was already a matter of the 19th century - during the first Opium War in the late Qing Dynasty, guns had not surpassed bows and arrows in performance.

Even if Bai Tu has the knowledge of a hard drive, it is impossible for cold weapons to be eliminated for a long time.

"I hope that the sample of Jiangxia repeater can make the progress of the Ministry of Industry faster." Bai Tu muttered to himself.

He was worried about "Zhuge Kongming", not "Zhuge Repeater......

Just equipped with a repeating crossbow, the combat effectiveness of the Jingzhou army is still limited, as if the battle report in front of him now - the mouth has still been defeated by Sun Ce.

However, if it was Wolong out of the mountain, Bai Tu would also feel some pressure.

Though...... Zhuge Liang should only be nineteen years old now, but the name of the person, the shadow of the tree, the ten philosophers of the dignified martial temple, whether ancient or modern, are the most shining one in the Three Kingdoms era, not to mention the side...... It's just a game with the theme of the Three Kingdoms, with Zhuge Liang as the prototype, and the number of times it is placed on the cover is also the most!

As for the other "guest" who was supposed to arrive in Jinling soon, Bai Tu didn't care so much, and just asked Kong Rong about that person......
