Wu Zhangsan asked about the relocation situation while mobilizing materials in Yangzhou City, and the Song army really did not launch a large-scale attack in the next two days, but I heard that siege equipment was being built in the camp, and I heard that Cai Jing recommended two generals to break the Ryukyu Army for Tong Guan.

It is said that Wei Dingguo is the best at using fire to attack people called 'Shenhuo General', and Shan Tingqi is the best at water warfare, and the two will arrive in Yangzhou in a few days, Cai Jing and Tong Guan both feel that with the same good use of water and fire, they will be able to break the Ryukyu thieves.

And in order to cover up the fact that his attack failed, Tong Guan lied that the Ryukyu thieves were powerful, and he fought with them in Yangzhou City to kill the enemy, etc., but the Ryukyu water thieves took advantage of the water to come and go freely, and it was difficult to conquer for a while, so he asked the imperial court to send more manpower, and then send more sailors and so on.

This kind of thing is the usual trick of these traitors, Zhang San is naturally not surprised, but Tong Guan mentioned the problem of the sailor and couldn't help but Zhang San didn't pay attention to it, Da Song paid attention to the fact that the sailor wanted to solve this problem on the water, so his pressure was great.

Just like there are now more than 500 large and small warships gathered near Jiankang, and the number is still increasing, this is the Yangtze River, there are so many ships that he fills up the river to a certain extent, even if you have a big speed advantage, it will become bullshit.

As for the so-called Shenhuo General and Shengshui General, others don't know Zhang San and don't know their details, the so-called Shenhuo General is just pushing the burning chariot like a red child and slamming it, but this thing is really good for breaking the formation, but that thing can't push the city wall, so he has a fart?

As for General Shengshui, this guy is really very watery, very watery, good at attacking with water, not good at water warfare as Cai Jing said, the ancient city walls are generally bricks and soil, if the water is irrigated, the foundation will inevitably loosen and the city wall will collapse, so the effect of this trick is also good.

But Yangzhou is the Yangtze River, Zhang San never believes that he has the ability to block the Yangtze River and release water to flood himself, so Zhang San is not afraid, and there is a canal to the east of Yangzhou, can the canal be blocked? OK! Can it be poured into Yangzhou City?

Zhang San threw this question to his staff department, because Zhang San himself was not very sure, and the water of the canal was not unflowing, the canal and other rivers intersected, and a large amount of water flowed into the Yangtze River through the canal, and Zhang San was not sure.

However, after the calculation and summary of the General Staff, it is basically impossible, the terrain around Yangzhou is open and flat, and there are no conditions for water attack, Zhang San is relieved, since the second general of water and fire is not afraid for the time being, Zhang San still considers the next move.

Now it has been almost a month since the occupation of Yangzhou, and the Great Song Dynasty monarchs and ministers have obviously not suffered enough, and they still have illusions, and their long-term battles are indeed a little underprepared, Zhang San originally planned to fight the Yangzhou campaign for two months, no more than three months at most, so the material preparation is in accordance with this standard.

But now it seems that things did not develop in the direction that Zhang San envisioned, Zhang San cut off the tax revenue of summer grain in Jiangnan, but that was only in Jiangnan, and the large land in the north of the Great Song Dynasty could still provide a large amount of tax revenue, so it can be said that this time was the richest time of the year in the Song Dynasty.

As for the grain, the same is true, the Bianhe River not only connects the south of the Yangtze River but also directly connects the Yellow River and the Huai River, counting on the shortage of grain in the capital, then the grain in other areas cannot be transported, but unfortunately it is the summer harvest now, but it is the time when the Great Song Dynasty is not short of food.

Zhang San now regrets that he had opened the station three months earlier, but unfortunately it was too late to say anything now, and he couldn't blame the General Staff, because Zhang San wanted to limit the General Staff and prevent it from having too much power, and Zhang San made strategic decisions like this by himself.

Xu Guanzhong is a smart person, but he is too smart and knows too much how to protect himself, so he sees very clearly what he shouldn't say and what he shouldn't do.

Complaining can't solve the problem, since it can't solve the problem by creating pressure on the imperial court, since the Great Song Dynasty monarchs and ministers think that the fight can be started, then Zhang San has to find a breakthrough from other people, and the person Zhang San is looking for is Tong Guan.

That's right, Tong Guan is a fortunate minister, but also a delusional minister, he relied on military merits step by step, so it is said that success is also military merit, defeat is also military merit, military merit is very important to him, Zhang San feels that as long as he knows that he can't win, then he will definitely accept the negotiation, as long as his interests are not moved, he will not mind sacrificing part of the interests of the Great Song Dynasty.

Moreover, Zhang San did not ask for much, as long as he could trade normally with the Great Song Dynasty, the Great Song Dynasty personnel were allowed to move freely to the Ryukyus, and the Great Song Dynasty was not allowed to interfere with his own tax collection at sea, just these three points.

Zhang San has the bargaining chips that Tong Guan wants, that is, the credit for the recovery of Yangzhou, Suzhou, and Hangzhou, so Zhang San is now waiting for the arrival of the new army, and after five days the training of the new army is completed, some troops will be able to complete the defense plan, and then Zhang San will be able to play with the opposite side with 30,000 more mobile troops.

It's just that Zhang San didn't expect that he hadn't started playing yet, Tong Guan on the opposite side played a big game for himself first, after the arrival of the two generals of water and fire, Zhang San didn't take it to heart, but he didn't expect that the holy water general on the opposite side gave him an accident.

First of all, Tong Guan ordered the troops to march and camp on three sides and five miles outside the city of Yangzhou, which was equivalent to being under the nose of Yangzhou, and then a large number of people were requisitioned in various camps and began to build low earth walls.

This is a common method of encirclement to build a long wall to prevent the enemy from escaping, breaking through and assaulting his own base, but Zhang San always felt that things were not so simple, and finally sent a message from Shi Qian, which was Shan Tingjue's idea, and the three walls plus the canal embankment formed a fence, and then the upstream water wheel carted water.

The water flow in the south is abundant, so the water level at the bottom is high, so it is still possible to store water in such a fence, Zhang San couldn't help but sigh that he didn't expect to be able to play like this, this guy is really a holy water general, and he plays with the water very slippery.

However, there is no magical suddenness when the plan is known, Zhang San is still in control of the east city wall, and the control of the canal embankment is still in his own hands, anyway, there are still two months before the flood season, Zhang San immediately prepared for them to dig the embankment themselves as soon as they dug the cofferdam.

As for why not in advance? Anyway, now that the other party is digging a ditch, he won't be fighting himself, Zhang San's strategy is to delay, and if he can delay it for one more day, it will take four or five days to repair the wall for dozens of miles anyway.

However, Zhang San felt that the other party should not be so idiotic that he couldn't think of this problem, so they knew that they controlled the canal embankment in their hands and dared to use this strategy, then it could only explain one problem, they had a way to make themselves have no chance to dig the canal when the time came.

There are many methods, such as setting up positions on the opposite bank to snipe the Ryukyu army digging the canal embankment, or setting up warships in the canal, but both methods have a premise, that is, the Great Song army must gain control of the canal!
