，

It has been more than a month since the destruction of Fuyang County, and along the way, the Qin army has successively broken the four counties of Fuyang, Liuxian, Xiao and Xu, and now the strength of Liu Bang's rebels has shrunk to the first line of abundance, and now the occupation has reached the most critical moment.

Surabaya County, Xiao County

Xiao County is adjacent to Fengpei, and now Li Chen's army is stationed in Xiao County. Although it seems that the capture of the four counties one after another has been a great victory, now Li Chen does not dare to easily attack the Liu Bang rebels on the front line of abundance.

First, since Liu Bang shrunk all his forces to the abundant line, the gap between the two sides has almost reached the point of being irreparable.

Second, the abundant generation is Liu Bang's birthplace and Liu Bang's ancestral land. Fighting here, Liu Bang simply occupies a favorable position and people.

"It's hard."

Li Chen threw the flag in his hand on the sand table, and the entire deduction sand table had been messed up.

"Master Hou, there is no chance of winning."

Chen Ping also had a sad expression, now the rebels on the entire front line of abundance are close to 150,000, although most of these rebels are farmers, hunters and the like, if it is a field battle, these people will naturally not be able to withstand the fight of the Shenwu army. Now Liu Bang is the one defending the city, and these 150,000 people are a piece of rolling wood and stone per capita, which can also bury the Shenwu army.

"Boom."

Just when the two of them were worried, the sand table in front of them was suddenly overturned. The two looked in the direction of the sand table overturning, yes, the person who overturned the sand table was the fool Du Shushao.

"You're insane." Li Chen was startled and looked at this fool angrily.

"I see that Hou Ye is upset when he sees this sand table, so he just overturns it." Du Shushao, a big fool, touched his head and said angrily.

"When you see it, you get upset, so you just flip it."

"Yes, overturn it." Li Chen muttered and repeated Du Shushao's words.

Damn, I have to rely on a fool to remind me at the critical moment.

"Fan Xu, if there is no obstruction from this city wall, we are somewhat sure of winning." Li Chen raised his head and asked Fan Xu.

"Master Hou, if there is no city wall, my old Fan dares to give you a packing ticket, it will definitely be the same scene as Fu Yang chasing rabbits." Fan Hao patted his chest and reassured.

"Come." The sand table had been overturned by a fool, and Li Chen walked to the map and shouted at everyone.

"One step in place, attack Pei County first." Li Chen pointed to the location of Pei County and said.

It's just that attacking Pei County is not an easy thing, Pei County is a big county, rich county. And its location is very special, it is on the transportation hub of the entire Daqin from south to north. Therefore, the city wall of Pei County is not the kind of earth rammed city wall of Fu Yang, but the bluestone city wall of the Eight Classics.

"Master Hou, our artillery can't destroy the city wall of Pei County, I'm afraid we have to go up the ladder." Wang Li reminded.

Even if you use a cannon, you can't fire solid shells, but even this can't destroy the bluestone wall. That is to say, the artillery fire attacking Peixian has changed from a weapon that plays a decisive factor to a weapon that can only be suppressed by artillery fire. In this way, the final means of deciding the outcome actually became the cloud ladder, and the cloud ladder siege was undoubtedly to fight for the lives of the soldiers.

"If you can't blow it up from the front, then you can't blow it up from below." Li Chen took the charcoal pen in his hand and circled the root of the Peixian city wall on the map.

"Blow it up from below, Hou Ye means digging a tunnel." Chen Ping was the first to react and asked tentatively.

"Yes, blow it up from below and set off a big fireworks for this group of rebels." Li Chen said.

"Then we'll have to make some movement up there, or we'll find out what we're digging underneath." Chen Ping voiced his concerns.

Coincidentally, the guard on the gate of Pei County is Zhou Bo again. To say that Zhou Bo and the Shenwu Army are really fateful, when the Shenwu Army broke through Fu Yang, Zhou Bo ran to Liuxian, but Shenwujin didn't long arrive in Liuxian County, it was difficult for a good woman to cook without rice, this Liuxian County is not as good as Fu Yang, needless to say that Zhou Bo naturally did not hold it.

In this way, Zhou Bo ran all the way, and the Shenwu Army chased all the way behind, and now the two sides met again in Pei County. After these battles, Zhou Bo was also discredited, and now the generals of the entire Liu Bang camp call him "Long-legged General" behind his back. If he hadn't had some friendship with Liu Bang, I'm afraid he would have been involved in military law a long time ago.

"Zhou Run, let's meet again, come out and fight with my Lao Fan for a few rounds."

"Zhou Runran, last time in Fuyang, your shoes ran off, let's help you pick them up, do you want more."

The mouths of the Shenwu Army are all very slippery, and scolding outside Pei County is not worth it to mock Zhou Bo.

Where could Zhou Bo bear such an insult, let the soldiers let go of the drawbridge and kill the soldiers out. He and Fan Xu fought for more than 100 rounds, and both of them were a little out of strength and then returned to their own camps to rest.

In fact, in this battle, Fan Xu had at least three chances to capture or kill Zhou Bo alive. But under Li Chen's advice, Fan Xu was not allowed to win, not to lose, but to draw and delay time.

Liu Bang has been a little irritable in recent days, the Qin army is just guarding the gate of Pei County, and they don't attack the city, but they just send troops to scold every day, but the results of these days are basically their own victories and defeats.

Fan Hao dragged time here, and the soldiers of the Shenwu Army underground also turned into groundhogs, digging tunnels in the direction of Peixian all day and night. Of course, Li Chen was not idle, he was in full swing to modify explosives.

The explosives in the Shenwu Army are naturally sufficient, but how to detonate them under the city walls has become a problem. But fortunately, the explosives bag is not difficult to make when the gunpowder tube is enough.

A certain amount of black powder particles are wrapped together, and several equal amounts of gunpowder are bundled into the same shape. In this way, the blast wave generated by each explosive bag in the ground is the same, making it easier to calculate the number of explosive packs needed to blow up this section of the wall.

After the step experiment of the explosive pack is completed, and after waiting for mass production, the next step is to make the lead part. The lead wire is an important factor to ensure safety, if the lead is not safe, I am afraid that the first person to die will not be able to guarantee it.

The manufacture of the lead is actually not complicated, and the wick of this era is no different, it is nothing more than longer and softer. Soak the spun cotton yarn in lamp oil to soften, and then knead the fine cotton yarn into long strips, the biggest difficulty in this process is to ensure that the new cotton thread can not be broken halfway. Finally, the kneaded fine cotton yarn is soaked in nitrate for a day, which will speed up the burning time of the lead.

The explosives package is getting more and more, and it is enough to blow up the county seat of Peixian County. And now the Qin army, which has become a groundhog underground, is getting closer and closer to Pei County, and the excavation work is becoming more and more dangerous. The closer you get to the walls, the later you can alarm the guards in the city. And once the city guards are alarmed, this plan will naturally be abandoned.
