Many teams have been sent out from below, but the team led by Lu Wu has not seen anyone for a long time, which makes Li Zhang very anxious, and he is also looking for people to inquire at the moment, and by the way, he also collects news from the underground.

As a result, Li Zhang soon found that these teams that sent people up all encountered the situation that the road ahead was blocked, but they still didn't dare to come up, for fear that the ghost beggars would dig up the blocked place and escape, so they could only send people to guard it to the death, and including Lu Wu, there were still some teams that did not come up, and it was likely that they did not encounter this situation.

However, Li Zhang was still a little anxious, and he couldn't wait to go down to check the situation by himself, but he also knew that he didn't have the ability to go down to the pit, and he was not even as good as an ordinary servant when he went down to the pit, so it was better to stay on it honestly and not make trouble.

After waiting for about two hours, it was already nearly evening, and finally the remaining teams sent people out one after another to contact, these teams did not encounter the situation that the road ahead was blocked, but they encountered the stubborn resistance of the ghost beggars, although these ghost beggars were inferior in weapons, but the space in the pit was narrow, it can be said that it was easy to defend and difficult to attack, so they couldn't fight for a while.

Lu Wu was the last to send someone out, and Li Zhang also immediately rushed to investigate, but found that neither Lu Wu nor the wild dog came up, and according to the people who sent out, after they first encountered the road blocked, the wild dog took them around another pothole, and as a result, they encountered the stubborn resistance of the ghost beggars, and the other party even built a rudimentary defense in the pit, which made them unable to kill at all, and now they can only guard the passage to prevent the ghost beggars from escaping.

With one news after another, Cheng Lin, who was in Kaifeng Mansion, also rushed here at this time, and after inquiring about the situation at the moment, he carefully checked the map again, and then showed a contemplative expression, because according to the collected news, most of the passages were blocked, and some of the remaining passages were easy to defend and difficult to attack, this is not a problem of fewer people, after all, with the terrain in the pothole, it is useless for more people to go down.

"Otherwise, we can only defend it, even if the ghost beggars in the pit have food, they must be limited, and we will consume them day by day, and they will always be consumed to death." At this point, someone spoke.

"No, if it's late, it will change, in addition to being good at drilling holes, ghost beggars are also good at making holes, what if they open a new channel to escape during this time?" However, as soon as the above person's voice fell, someone immediately spoke out against it, and this person's concern was also very reasonable, so the others also nodded in agreement after hearing it.

While others were discussing how to proceed with the next move, Li Zhang was carefully looking at the drawings in front of Cheng Lin, this picture was the original drawing drawn by the wild dog, and the places where the various potholes were blocked on it were also marked, and the remaining potholes were also easy to defend and difficult to attack, especially the potholes were not on a plane, some of the potholes were overlapped, and some had huge slopes, which brought great difficulty to the attack.

However, Li Zhang soon saw something from the drawings, only to see that he suddenly picked up the pen next to him, and then made a few marks on the potholes: "Cheng Fuyin, the remaining potholes are easy to defend and difficult to attack, since this is the case, let's stop attacking, just plug them up!" ”

"Huh? Li Duwei means ......" Cheng Lin said with a puzzled expression when he saw Li Zhang's operation, because Li Zhang actually blocked all the remaining potholes, so the ghost beggars couldn't get out, but how could they attack it?

"Cheng Fuyin, please see, in this area that is guarded by ghosts and beggars, there is a main pit and seven or eight branch lines, I just looked at it, the northwest branch line is the highest, and the sewage used to flow into the main pit from here, but if we replace the sewage with oil, hehe~"

Li Zhang didn't say anything more when he said this, and Cheng Lin and the others couldn't help but feel excited, and the scene of countless ghost beggars wailing in the fire flashed in their minds. Speaking of which, their gang of people are civil officials in the end, unlike Li Zhang, who has mixed up on the battlefield, so I didn't expect such a ruthless method to be normal, of course, it may also be that they cherish their feathers, even if someone thinks of it, they don't want to say it, after all, this method is really hurtful.

"Ahem, what do you think of Captain Li's method?" Cheng Lin was stunned for a moment, and then asked for the opinions of others.

"I think it's doable!" At this time, someone was the first to agree, and then the others also nodded, which made Cheng Lin also nod with satisfaction, and then immediately ordered to plug all the potholes that could not be attacked, leaving only the branch hole in the northwest direction, and at the same time requisitioned a large amount of fire oil to the army.

When it was almost the second watch, the fire oil was finally delivered, and the remaining passage was also blocked, and then Cheng Lin personally led people to the location of the northwest branch cave, where there were also people from the government to guard, and then barrels of fire oil were poured down, fire oil is lighter than water, so it can float on the surface of the water, and flow along the terrain to the main pit and other branch holes.

With the fall of the fire oil, the ghost beggars in the cave also quickly noticed, after all, the smell of fire oil is relatively strong, and it floats on the water, so it is naturally easy to be found, which makes the ghost beggars in the cave also guess the idea of the government, so these people also began to rush out desperately, after all, they would rather risk death than burn to death in the cave.

But it is a pity that although there are many sewers in this blocked pothole, each sewer is heavily guarded, and some of the sewers are directly crushed to death by boulders, and it is impossible for anyone to escape, so these people's efforts are doomed to be in vain.

"Ignition!" In the end, I don't know how much fire oil was poured in, with Cheng Lin's order, someone immediately threw down the torch, and a fire immediately burned in the pit full of fire oil, Li Zhang was afraid that it could not be fully burned due to lack of oxygen, so he asked people to go to some workshops to borrow a blower, and the soldiers operated the air to blow in, and let the fire inside burn more and more by the wind, and thick black smoke came out of each drain.

In fact, Li Zhang also knew that there was no need to blow the wind at all, because even if the fire oil could not be burned due to lack of oxygen, the ghost beggars inside would definitely die due to lack of oxygen, but Li Zhang was still worried that there would be fish that slipped through the net, so he decided to let the fire burn for a while, anyway, the fire oil inside had already been poured in, and if it was not burned clean, it would pollute the environment if it was discharged into the Bianhe River.

With the burning of the underground fire, at first from the sewer can still hear the screams of the ghost beggars inside, and even some of the ghost beggars covered in fire rushed out of the sewer desperately, but they were immediately shot by the archers, and in the time of waiting for about a cup of tea, there was no sound in the pit anymore, only the burning sound of the fire, and the billowing black smoke that came out, and even the black smoke was filled with a smell of roast meat.

Li Zhang covered his nose and found a place upwind, trying to avoid the smell of roast meat, but unfortunately this burning area was too big, and now that the rain has stopped, the wind direction has become erratic, one will go east and one will go west, no matter where he hides, it is useless, and in the end he can only wrap a wet towel around his face.

The fire spread along the potholes, and finally the soldiers who stayed behind couldn't stand it, and fled to the ground, after all, although the potholes below were blocked, but in fact they were only blocked by big stones, although people couldn't pass, but there were still a lot of gaps, and now the smoke and fire came out of the cracks, and if they didn't come out, they would have to follow in the footsteps of the ghosts.

The fire burned all night, and by the next morning, the ground that had been muddy due to heavy rain had been dried up, and in some places there were large cracks, and the whole right compartment exuded the smell of barbecue.

"This method hurts the heavens and the peace, aren't you afraid that you will be called ruthless in the future?" Lu Wu was walking on the street at this time, looking at this area and asking Li Zhang next to him.

"Someone has to do some things, and I don't care what people think of me, I just want to have a clear conscience." Li Zhang said quite easily at this time, ghost beggars are known as the biggest stubborn disease in the capital, every year because of ghost beggars cause women and children to disappear countless, and these women and children are extremely miserable, either tortured and died tragically, or sold as prostitutes and **, accumulated over the years, just the case files related to ghost beggars in the Kaifeng Mansion filled three rooms.

"That's right, just ask for a clear conscience, so at least you won't be too tired to live!" Lu Wu showed a somewhat thoughtful expression when he heard this, and then suddenly turned his head and smiled, "Now that the fire has been extinguished, someone will be sent to collect the corpse of the ghost beggar in the afternoon, do you want to go down and have a look?" ”

Hearing Lu Wu's words, Li Zhang's face immediately changed, and he waved his hand again and again: "Excuse me, I still have something to do, Uncle Wu, you should go down with Cheng Fuyin!" ”

Li Zhang didn't want to witness the tragic scene of roasting the living with his own eyes, he was mainly afraid that he would have nightmares, not to mention that the smell of barbecue this day and night had already made him nauseous and wanted to vomit, if he really went down to the pit, I was afraid that he would vomit out all the bitter bile water.

However, Li Zhang finally saw these roasted ghost beggars, because Liu E gave an order to pull the roasted ghost beggars to show the public all over the capital, in order to warn others of the fate of the ghost beggars, after all, although these ghost beggars have been cleared, the drainage potholes are still there, and those blocked potholes have also been dredged again, and new ghost beggars will inevitably breed in the future.

Of course, the imperial court did not have any precautions against this, in addition to pulling the corpse of the ghost beggar to show the public, some key positions in each pit also added strong iron fences, although the iron is corroded, and it may also be destroyed, but it is better than nothing.

However, although the ghost beggar was exterminated, there was one thing that had been pressing on Li Zhang's heart, although he did not go to the pit in the end, but the wild dog went, and he also carefully identified the corpses inside one by one, except for a few ghost beggars who were burned to death, most of them died of suffocation, so the facial features can also be recognized, but the ghost beggar spent a few days identifying them one by one, but he still did not find the body suspected of being Shui Yuanzi.
