Yuan Shu was obviously preparing to personally protect Shouchun City this time, so it was no wonder that Yuan Shu would send an envoy to Zhu Wei's side.

Since Yuan Shu wants to defend Shouchun City, he naturally hopes to have more chances of winning, so it seems that he sent an envoy to Lu Bu's side, maybe it is also true, maybe he has really said that Lu Bu has moved, so that he can be more confident to stay in Shouchun City and defend it.

But no matter what, in the original history, Cao Cao, Lu Bu, and Liu Bei attacked Shouchun, and Yuan Shu left four generals plus 100,000 soldiers and horses to defend the city, but now although Zhu Wei has been added to participate in the attack on Shouchun, Yuan Shu's side has also become Yuan Shu personally defending the city with nearly 150,000 or 60,000 troops.

With Zhu Wei's army also officially sending troops from Hefei to the direction of Shouchun, the situation of the four coalition forces besieging Shouchun has also been achieved, but the battle situation in Shouchun City is indeed a little unpredictable.

This Shouchun City is indeed an unusual big city.

Shouchun City is the end capital of Chu during the Warring States Period, and it was originally the last royal capital city built by Chu State in order to continue the national fortune and migrate to Jianghuai, so Shouchun City can be regarded as the second largest city in the world after Yanxiadu, the capital of Yan State, in the capital of various countries during the Warring States Period.

As mentioned above, the location of Shouchun has natural barriers such as Bagong Mountain and four rivers in theory, and specifically to this Shouchun City, it is a huge city with a water in the north, Dongjindu in the east, West Lake in the west, and Shilitou in the south, covering an area of about 25 square kilometers.

Among them, the south and north two city walls are six or seven miles long, the east and west two city walls are about four miles long, the city wall is six or seven stories high, the bottom of the city wall is about forty or fifty steps wide, and the city guard city above the city wall is also nearly twenty or thirty steps wide, which can allow Yuan Shu's soldiers to arrange various means of defending the city on it.

Therefore, although Shouchun City seems to be located in a low-lying place, it is also like a behemoth, lying on the plain formed between the waters of the Jianghuai River.

Although the walls of Shouchun City are mainly constructed of rammed earth, they can be filled with glutinous rice juice and stones as the base, so the city walls are also strong and abnormal, and they cannot be easily destroyed.

At the same time, although the huge Shouchun City has four gates in the east, south, west and north, there are also urn cities like military forts built outside the walls of the four gates.

The height of the city wall of this urn city is about two people lower than the main wall of Shouchun, but there are also three or four stories high, five or six steps wide, and in addition to the south gate, the urn city gate of the east, north and west gates are not in the same straight line as the main city gate, the west urn city gate is open to the north, the north urn city gate is open to the west, and the east urn city gate is about four steps parallel to the main city gate.

In this way, if the foreign enemy wants to attack the gate of the urn city, he will attack from the side near the direction of the main city wall, and will naturally be assisted by the defenders on the main city wall.

The most important thing is that this kind of urn city structure is outside the city wall, which can make the Shouchun city wall appear concave and convex structure, so that the defenders on the city wall can have more attack surfaces to attack the attacking enemy.

I have to say that Yuan Shu re-strengthened Shouchun City, the capital of ancient Chu, to form a Jianghuai city that was easier to defend and difficult to attack.

The huge city can accommodate more than 100,000 troops and nearly 100,000 people under Yuan Shu's account, so that Yuan Shu has enough troops to defend the city, and if necessary, tens of thousands of young people can be requisitioned to use it.

The strong city walls and the external urn city can also greatly improve the defense of the city, not to mention that there is a moat at least twenty steps wide outside the city wall.

The turbulent water of this moat connects the Huaishui and Huai River, which gives Shouchun City a natural protection, and it is not easy to fill the channel on such a moat.

Even if it is now the four allied forces of Zhu Wei, Cao Cao, Lu Bu, and Liu Bei besieging Shouchun City, it is still not an easy thing to break through the city.

Relatively speaking, the south gate of Zhu Wei's main attack is easier than the other three city gates, after all, the urn city gate outside the south gate and the inner city gate are on the same line, as long as the urn city is captured first, you can directly face the main city gate in the inner city.

But this Shouchun City is even more difficult to fight than the Xiangyang City that Zhu Wei faced before, and Zhu Wei's attack on Xiangyang City was also entered through the Water Gate, and it was not really attacked by force, but now this Shouchun City is afraid that there is no possibility of tricks.

There are indeed two small water gates in this Shouchun City on the north gate, but the north gate is Cao Cao's attack area, so naturally Zhu Wei can't use it, and the water gate of Shouchun City is not an official city gate, just a small waterway connecting the inside and outside of the city, and Yuan Shu is easy to construct a defense of the urn city inside.

Just like what Zhu Wei and Cao Cao roughly agreed before, now Zhu Wei, Cao Cao, Lu Bu, and Liu Bei are camped about two or three miles outside the square gate of Shouchun City, and then they each contracted a city gate to attack, but the main thing is that they are fighting separately, and there is not much intention to join forces.

However, after Zhu Wei's army camped outside the south gate of Shouchun, Lu Bu and Liu Bei quickly sent envoys to Zhu Wei's side, but they asked Zhu Wei's side for help.

Compared with Cao Cao and Zhu Wei, Lu Bu and Liu Bei are weak after all, and they also have no siege equipment.

But the current situation is that they didn't even have a chance to get close to the Shouchun city wall before they could fill the moat of Shouchun.

Therefore, Lu Bu and Liu Bei both asked Zhu Wei to borrow siege equipment, obviously they had already heard that Zhu Wei had a cave house car that could safely fill the moat, as well as a thunderbolt trebuchet for siege, a siege arrow tower or something special equipment, so they all wanted to borrow it from Zhu Wei.

Of course, Lu Bu relied on the old connection with Zhu Wei, and the two sides were allies, so he sent Chen Deng as an envoy to ask Zhu Wei for siege equipment.

And Liu Bei was much more polite here, only saying that he was borrowing, and he was willing to give some trading things as a thank you.

After all, Liu Bei and Zhu Wei actually don't have much contact here, Zhu Wei was targeting Xuzhou's side before, but he only befriended Lu Bu but didn't hand Liu Bei any olive branch.

Obviously, Zhu Wei has some disdain for Liu Bei, who now relies on Cao Cao to garrison troops in Xuzhou Xiaopei.

Liu Bei also knew about his own affairs before, so although he knew that there was a transaction between Zhu Wei and Lu Bu between grain and war horses, he only looked at it with envy, but he didn't mean to take the initiative to climb the relationship.

But this time Liu Bei still took the initiative to send someone here, and the messenger sent was Liu Bei's brother-in-law Mi Zhu, but Zhu Wei suspected that Liu Bei came to ask for siege equipment this time, regardless of his face, and it was very likely that Cao Cao's meaning was behind it.

After all, in terms of the relationship between the four alliances today, the relationship between Lu Bu and Zhu Wei is relatively close, and the relationship between Liu Bei and Cao Cao is relatively close, so Liu Bei should be looking for Cao Cao's help to support the siege equipment, and should not come to Zhu Wei, who has nothing to do with it.

But now Liu Bei actually took the initiative to find Zhu Wei and found Zhu Wei, who had nothing to do with him, which is a bit unusual......
