Chapter 33: The Eve of the Tunnel War

It is said that after the scouts entered the tunnel, they marched all the way to Changsha City, and also made measurements and various marks along the way. This tunnel is unusually wide, wider than any tunnel dug by the Shu army in the past. Perhaps Lu Xun planned to transport a large number of soldiers into the Shu camp for a sneak attack in a short period of time, so the tunnel was dug very wide.

It's just that he probably didn't expect that one day, this wide tunnel would cheapen the enemy. At first, the passage continued to go down, and when it came to a depth of one zhang, water began to accumulate on the ground, and it seemed that the groundwater here was quite abundant. A long line of soldiers lined up, and the fish carried water out with wooden barrels, there was no way, and the keel waterwheel in this kind of place was not easy to erect, so it could only be drained by the most primitive method.

Fortunately, the tunnel is wide enough, not to mention that many people walk side by side at the same time, even if you take a carriage, there is no problem. And the Shu army has tens of thousands of people, so manpower is not a problem, but it really took some effort to get the buckets together.

The scout waded through the water all the way down, and according to the measurements, it was supposed to reach the deepest point at the bottom of the moat, where the water level was already chest-deep. After bypassing the bottom of the river, the tunnel turns upwards and the water level slowly becomes shallower, until it is out of the waterlogged area, which is not far from the ground.

The scout arrives at a pile of bricks and rubble that blocks the entrance to the tunnel. Comparing the measurements of the scouts in the tunnel with the aerial hot air balloon reconnaissance data, intelligence analysts quickly found the location of the entrance to the tunnel.

Balloon scouts took a detailed look at the place with telescopes from the air, and found that it was an abandoned manor house about 20 feet from the city walls. The entrance to the tunnel is likely to be inside a collapsed house on the manor. It is speculated that the Soochow people should have started digging tunnels in this house before, perhaps to hide people's eyes, or maybe simply to shelter from the wind and rain.

Anyway, no matter what the reason, the opening of the tunnel should be in this house, as for why the house collapsed, it is estimated that the reason is also very simple: after the failure of the sneak attack, the Dongwu people deliberately knocked down the house in order to avoid the Shu army from pursuing from the tunnel, and used the bricks and rubble of the house to block the tunnel entrance.

The Soochow people not only blocked the tunnel entrance, but also arranged a small team of soldiers around the tunnel entrance to guard it. The aerial scouts even saw in their telescopes that at intervals there were people lying on their heads with their heads lying on their sides, presumably with a large urn buried underneath their heads. This is using an urn to monitor the movement underground.

It seems that Lu Xun is not unpredicted whether the Shu army will counterattack with the help of his tunnels, and he has also taken sufficient precautions. is worthy of being a wise man in Eastern Wu, and it is really not easy to match.

Soon, all the information was gathered in front of Liu Hou's case, along with a map full of various markers. The brainstorming military meeting was reconvened, and the generals continued to discuss the next course of action.

Liu Hou nailed the map to a wooden board that was erected, held a small stick in his hand, and pointed to the map to teach, which looked like a teacher holding a whip and pointing at the blackboard to teach:

"Looks like this is the opening of the tunnel. But this place has been blocked, and the Dongwu people are heavily guarded here, so it is basically impossible to launch a sneak attack from here, and it seems that our plans need to be adjusted slightly. ”

"Not only that, but please look here." Guo Youzhi didn't have a whip, so he could only point to a road in the map, "This is a pond, a very large pond, with an incredible amount of water, enough to flood the entire tunnel." And the tunnel just passed by this pond, and in this location, the closest place to the pond, there were about a dozen people with hoes lingering for a long time, and everyone think about it, what do they want to do? ”

As he spoke, Guo Youyi circled the location of the pond on the map, and then clicked his finger a few times at the place where more than a dozen people were staying.

Except for the vulture bone and the Ehuan nerve firing arc are relatively long, and the head rotation speed is relatively slow, everyone else is not stupid, and they all heard what Guo Youzhi meant.

"With all the power of their hoes, the dozen or so men can dig a passage between the pond and the tunnel in less than a quarter of an hour, and then the pond water will pour into the tunnel. What a vicious Lu Xun. Guan Xing hated the authentic.

"It seems that Lu Xun is more cunning than we imagined. He didn't completely block the tunnel, it turned out that he was planning to yin us. Fortunately, we have complete air supremacy, and their every move cannot escape our eyes. ”

This hot air balloon is like an early warning aircraft and spy satellites, with them, the Shu army and the Eastern Wu army are completely asymmetrical in information, if this still can't win this battle, Liu Hou should really go back to hit tofu.

"In the light of these circumstances, we must pay attention to two things: first, we cannot attack from this original opening. There are too many guards here to sneak attack. We had to avoid this opening and dig a new opening in a weakly guarded spot, so that we could carry out a sneak attack without us knowing.

Also, in addition to having few guards, this place used to make a new opening must also meet one condition, that is, the tunnel is very shallow and very close to the ground. Because the enemy is everywhere with urns to listen, our slightly more vigorous digging action will be detected by the other party. Therefore, the thinner the surface of this exit, the better, preferably thin enough to be pierced with a gentle shovel, so as not to be heard by the other party's urn as much as possible. ”

Liu Hou said so, he also knew that it was impossible to find a place where the ground was as thin as paper, after all, there were people walking on the places where the tunnel passed, so these places must have a certain thickness, otherwise it would be impossible to bear such a large weight. It seems that this task is not so easy to complete, and silent excavation is not so easy to do.

He hates Wengting very much now, and he really doesn't understand how the ancients were so smart and could invent such a technology, which is simply the predecessor of sonar.

"The second point is that we must deal with the dozen or so people by the pond as soon as possible, or we must deal with them silently, and then control this place. Their presence is too harmful to the entire tunnel. Therefore, this point has become a place that must be defended, and it cannot be snatched back by the Soochow people no matter what. After the start of the war, this will become the key point of the whole battle, and it will be an important factor in the success of our 'indecent assault' operation. Therefore, it is necessary to send heavy troops to guard here, and there is absolutely no room for loss here. Liu Hou was categorical.

Guo Youzhi pondered for a while and said: "A certain view of this place must be a relatively superficial place in the tunnel, and it is better to open the tunnel mouth here." When the time comes, our soldiers will continue to go out from here, and there will be no need to worry about whether they can defend it or not. ”

"Mr. Guo, why do you see that this is a superficial place?" Zhang Bao, who was unwilling to be lonely, finally said something and asked this question that everyone wanted to know.
