It is indeed very rare to have such heavy rain in spring, and the rain in the Qingming season is not fake, but most of it is drizzle, and it is said that the spring rain is as expensive as oil, and the rain can no longer be gentle.

But this heavy rain was like a pour, and it was several hours at a time, and the water in the low-lying places was several feet deep, which made people suspect that it was not spring but autumn.

For Lu Zhao, this heavy rain from the sky is simply like divine help, so that the fierce offensive of the Bingzhou army came to an abrupt end, what could be better than such a thing, the continuous battle made the Jizhou army tired, this heavy rain undoubtedly won them some respite.

Lu Zhao even hoped that this heavy rain would not stop, and it would be best to rain for ten days and a half months, so that when Sima Shi's reinforcements arrived, the crisis in Xindu would disappear.

But Lu Zhao never dreamed that just when he was celebrating with the crown, a devastating disaster had already befallen him, because his fate was in Cao Liang's thoughts.

If it is said that Cao Liang is still hesitant to dig the embankment, this heavy rain will wash away his doubts, peach blossom flood and heavy rain, this is simply a perfect combination, and the flood letter is already a certainty.

The opportunity must not be lost, and the loss will not come again, taking advantage of the time when the water level of the Zhanghe River and the Qinghe River is soaring, it is the best time for water attack, if you miss this opportunity, and wait until the water level falls, I am afraid there will be no chance.

Cao Liang immediately made a decision, and immediately sent Wen Qin to lead a part of the Xiao Cavalry Battalion to the upper reaches of the Zhanghe River, and sent Deng Ai to lead a part of the Yue Cavalry Battalion to the upper reaches of the Qinghe River, and agreed that when the Son of Heaven was the day after tomorrow, both sides would burst the embankment at the same time to release water.

The reason why it was set at the time of the day after tomorrow instead of early tomorrow, Cao Liang had his own considerations, after all, the battalions of the Bingzhou army were still in the low-lying places outside Xindu City, and before the flood came, they had to move first, and Cao Liang had to leave enough time.

Moreover, it is not the best period for the levee to burst now, the flood peak in the upper reaches has not yet arrived, and only when the water level of the Zhanghe River and the Qinghe River rises to the highest point, then the embankment will burst, and the effect will be the best.

After Cao Liang gave the order to the Xiao Cavalry Battalion and the Yue Cavalry Battalion, he immediately rushed to the infantry battalion, gathered all the four generals of the infantry battalion, and Huan Fan announced the order to transfer.

There is only less than a day and a half left before the levee breaks and the water is released, so the transfer of the state army must be fast, otherwise the flood will not be recognized by the six relatives, and if the state army does not have time to withdraw, it will suffer first.

Cao Liang had already planned the place of transfer in advance, although the area around Xindu was low-lying, there were still some highlands in some nearby places, even if the water of the Zhanghe River and the Qinghe River attacked at the same time, these highlands would not be flooded, and as long as the state army withdrew to these designated highlands, they could sit back and relax.

However, the biggest difficulty now is this heavy rain, it has been raining continuously for half a day, and there is no sign of stopping until now.

After all, the entire Bingzhou Army not only has tens of thousands of men and horses, but also countless materials, baggage, and heavy equipment, these things are not something that can be easily given up, and when the Bingzhou Army is transferred, it must consider how to place these things.

However, no matter how difficult it is, after the order to transfer is issued, each battalion must act immediately, and there can be no more hesitation, because when the time comes, the Xiaocai battalion and the Yue cavalry battalion will burst the embankment and release water, and this flood is ruthless, but no one will admit it.

This was the most intense of the big transfers, all four infantry battalions were busy nervously, dismantling tents, packing up, the whole process was done in the pouring rain, and before they could leave the camp, these soldiers were already drenched in soup.

Even if the weather is still extremely cold, even if the whole body is drenched, these state troops still have no complaints, after all, with the help of the power of the flood, it also exempts the lives of the state army, in just a few days, the state army has lost thousands of people, compared with these dead robes, they are drenched in a little rain, how happy it is.

Catapults, crossbow vehicles, siege vehicles, and baggage trucks were also transferred with the infantry of the state, and these equipment were the magic weapons that the infantry battalions relied on to survive, and they could not be out of the way, so they were all in the sequence of priority transfer.

Fortunately, there was plenty of time, and after receiving the order, the men and horses of the battalions were already actively prepared, and the equipment was transferred overnight, and the last group of soldiers left the empty camp only by noon the next day.

Of course, the transfer is not their only task, after reaching the high ground, they have another important task to do, that is, to build a raft.

Jizhou is located in the north, even if there are two rivers such as the Zhanghe River and the Qinghe River in the Xindu area, but the military and civilians of Jizhou can not rely on the water to draft water, after all, the Zhanghe River and the Qinghe River are not the kind of big rivers, the seasonal water flow is more obvious, the water flow is turbulent in the flood season, and the riverbed is bottomed out in the dry season, and the number of fish and shrimp in the water is limited, which is not enough to feed many fishermen.

What's more, even a few fishermen are estimated to have been pulled out in the forced recruitment two years ago, and as for their fishing boats, they were also burned down by the order of Jianbi Qingye.

As for the burning of these fishing boats, some people will ask questions, is this necessary? It doesn't seem to be, but there is nothing wrong with being careful, the walls are clear, and nothing can be left to the state army after all.

Therefore, in the Xindu area, it is almost very difficult to get a ship, and it is obviously too late to build it temporarily.

However, this is not difficult for Cao Liang, shipbuilding requires professional craftsmen, but rafts are not used, on the Jizhou Plain, there are large areas of woodland, and the state army can cut down trees to build rafts. There is nothing difficult about the construction of a raft, it is just a matter of attaching the logs together with nails or ropes.

It's just that the difference between a raft and a boat is that the carrying capacity of a raft is relatively limited, a raft can only carry a few people, while a large ship can sit hundreds of people, so the construction of a raft can only be based on the number of wins, the more the merrier.

Another difference is that the boat can adapt to different waters, even if the water is very deep, there is no need to worry, and rafts are only suitable for use in shallow waters, this is suitable for use in the Xindu area, after all, after flooding the plain, the water will not be too deep.

When Xindu is reduced to a water town, the state army can take a raft and go down the river to reap the victory.
