The last three kingdoms

Chapter 1192
When the siege battle entered a stalemate, it was very beneficial to the Han army defending the city. The Wu army is now trapped in food and grass, and the time for combat is limited. After all, the food and grass expenditure of 20 horses is definitely not a small amount. , although Lu Kang has ordered Zhu Wan to forcibly collect food and grass around Luoyang, Liu Yin seems to have made preparations in advance, and implemented a solid wall to clear the fields around Luoyang. The ground was green and yellow, so although Zhu Wan tried his best, he couldn't collect much food and grass.And this is a drop in the bucket, and it can't solve Wu Jun's urgent needs at all.

As the coach, Lu Kang was under a lot of pressure. Sun Xin was in charge of the siege, so he could just focus on the siege, but for Lu Kang, he needed to consider all aspects of affairs, the issue of food and grass, and The coordination of the Kwantung Army and the problems of the Han Army in Xingyang and the Han Army in Luonan, all these aspects need to be considered and dealt with by Lu Kang.

With the depletion of food and grass, the time left for Lu Kang is getting less and less. There is no progress in the matter of siege, and the surrounding situation has deteriorated. A lot of soldiers and horses came, but to deal with the ace cavalry army of the Han army, the army of the Three Kings of Kanto was obviously not enough.

As for Luonan, there was no good news. Although Sun Xiu had already gone north to Luyang, Lu Kang had no idea whether he could hold back the 10,000+ Han army in Luonan.

Sun Kai's tunnel attack plan had been reported to Lu Kang a long time ago. Although Lu Kang believed that tunnel attack was not reliable, under the current circumstances, tunnel attack was one of the few options. Lu Kang couldn't be sure if he couldn't make a surprise attack. In the current situation, he could only treat a dead horse as a living doctor.

Fortunately, the way of siege, such as the tunnel siege, is progressing very smoothly. Compared with the current situation, the Han army did not notice the Wu army's actions and took effective measures. For Sun Kai , is undoubtedly the biggest advantage, now that the Wu army has dug the tunnel under the city wall of Luoyang, as long as it persists for another three or two days, the Wu army can attack Luoyang from the tunnel and launch a sneak attack.

In fact, the most difficult part of the tunnel has already been dug. The most difficult part is how to dig under the moat. Authentic soldiers will also be drowned alive in it.

This was of course a problem that Sun Kai had to overcome. The moat in Luoyang was connected to the Luoshui River. It was wide and deep. When tunnels were dug under the moat, great care had to be taken.Sun Kai adopted the "U"-shaped method, that is, when digging below the moat, use the section that is dug deeper to avoid the upper water flow.

Wu Jun's tunnel is not just as simple as digging a passage. First of all, the passage must be kept unobstructed, and there must be no landslides and water seepage. While digging forward, a large number of beams and columns must be used for support. As long as it is durable, even if a large army passes through here, it can be supported.

Now Wu Jun has dug under the city wall, and the most difficult part has been dug through. The rest is to choose the exit in the city, and everything will be done.

In the past few days, Liu Yin has also boarded the city walls of various places in Luoyang to inspect, to fill in the gaps and see if there are any unfinished business.Liu Yin naturally saw the Wu army camp not far from the east wall.

It stands to reason that Wu Jun's camp usually chooses a place some distance away from the city to set up a stronghold. In this way, it is possible to prevent the army defending the city from launching a sudden attack, thereby disrupting Wu Jun's plan.

The other three sides are relatively normal, only the Wu Jun camp on the east side seems a bit out of place, but Liu Yin didn't take it too seriously at first, after all, he has seen such a way of camping.

But Liu Yin soon discovered that after the siege was over every day, when the Wu army retreated, they did not all enter these camps, but retreated to another camp that was farther away, which made Liu Yin feel It's very strange, could it be that these tents are used for something else?
Thinking of this episode, three words popped out of Liu Yin's mind: Tunnel warfare!
It is not uncommon in history to dig tunnels to attack the city. In fact, as long as the siege lasts for several months, there will be such means as digging tunnels to attack the city. However, tunneling is an auxiliary means of attacking the city. Is it possible? Will Wu Jun adopt this time-consuming and labor-intensive method in the limited attack time of more than ten days?
So Liu Yin immediately ordered several pits to be dug in the city, and a huge urn was buried for the soldiers to hide in.This method is the most effective way to deal with tunnel siege. As long as the Wu army takes action, the soldiers sneaking into the urn can hear some abnormal noises, and based on the sound, they can further confirm the location of the tunnel. .

Sure enough, Liu Yin's suspicion was confirmed, and the Han soldiers listening in the urn could clearly hear the movement coming from the ground.

After receiving the exact information, Liu Yin did not take action immediately, but further monitored Wu Jun's movement to confirm the specific location of Wu Jun's tunnel and exit, and took corresponding countermeasures.

The most effective way to deal with tunnel siege is to attack with water. As long as the water from the pool or well in the city is led into the tunnel, no matter how many people are inside, they will all be drowned alive.After Liu Yin determined the location of the tunnel, he led the pool water in Luoyang City to the vicinity of the tunnel. Since he wanted to play, he would play with a big one.

Finally, the soldiers listening in the urn could not hear any sound, and reported it to Liu Yin, and Liu Yin understood that the Wu people's tunnel had been completed, and the Wu people might not dare to act during the day, only at night, they would take advantage of the emptiness. Only when you move will you launch an attack.

It was night, and Sun Kai personally led thousands of elite soldiers into the tunnel one after another, preparing to launch a surprise attack on Luoyang City at midnight.

But at this moment, a disaster suddenly fell from the sky. A flood of water from nowhere suddenly poured into the tunnel. The water was so strong that the entire tunnel was filled with rat holes. Countless Wu soldiers poured in densely. This time, there was not even a chance to struggle for their lives. The pool of water poured down, and thousands of Wu soldiers were drowned alive in the tunnel.
