"Success or failure in one fell swoop, siege!" Wang Linjian pointed to Kunyang.

"Kill!" Tens of thousands of vanguard troops flocked to the city of Kunyang.

On the tower of the city, Ren Guang commanded the Zhuge Lian crossbow battalion, and the company flipped and shot into the enemy soldiers that hit, whoosh! Countless arrows rained down from the sky, causing the enemy soldiers to fall in pools of blood, and there were extremely terrible screams.

However, the enemy army still rushed forward in a swarm as if it had been beaten with chicken blood. Even if there is death and no life, there are piles of bones, and they will never retreat.

Ren Guang's scalp was numb when he saw it.

The enemy army fell in the thousands, and the soldiers in the back immediately took the place.

Zhuge had only 1,000 crossbowmen, and after a wave of blows, he had to delay a little time, replace them with arrows, and then shoot again.

"Give me a ladder!" The vanguard general Gao Chong shouted angrily, looking at the countless soldiers who fell to the ground, Gao Chong's eyes were red.

He rushed to the city gate to command, and he was brave and fearless.

Hohoo! A battalion of 20,000 people marched to the bottom of the city.

Before climbing the wall and ladder, he was pushed down the city by the Han army defending the city, and fell down with the ladder, as well as countless soldiers who climbed the camp. A wall of more than ten feet fell down, and people became flesh and blood.

Several waves of siege ended in failure.

Gao Pet gritted his teeth: "Give me artillery, hit hard!" ”

"Reload, shoot!" 50 artillery pieces were pushed to, at a distance of 200-300 paces below the city, boom! The cannon burst into the chamber and exploded over Kunyang City, with a deafening sound.

The artillery fired in unison, the power was huge, but compared with the reinforced and heightened Kunyang city wall, it was like a mayfly shaking a tree.

After the shell exploded, it left only a black mark on the city wall.

"What?" Wang Lin was shocked, the reward given by the summoning system couldn't knock down the city wall.

After attacking for half a day, he did not take advantage of the slightest advantage, and he also lost his troops, so Wang Lin had to order to return to the army to rest.

"Kunyang City is so strong, what should I do?" Wang Lin frowned a little.

Jia Xu half-squinted his eyes and said: "It is not possible to attack by force, our army has suffered too many casualties." ”

"I wonder what the gentleman has planned?" Wang Lin knows that Jia Xu is a person, as long as he speaks, it shows that he already has a strategy in his chest.

"Didn't Your Highness bring a special force? Playing Kunyang just came in handy. Jia Xu woke up Wang Lin with a word.

Before leaving, Wang Lin brought a team of construction troops, which were best at digging tunnels, digging underground tunnels into the enemy's city, and breaking through from the inside.

Playing red eyebrows and bronze horses has been tried repeatedly, and even the battles have been victorious, and people have sent the ace army.

"What the gentleman said is very true!" Wang Lin nodded yes.

Wang Lin summoned the engineer commander and asked him to act tonight, within fifteen days, to dig the tunnel into Kunyang City.

......

In Kunyang City, the Marshal's Mansion in the North.

"Sir, I'm always feeling restless these days, will anything bad happen?" Liu Xiu and Liu Bowen are discussing countermeasures.

"What is the lord worried about, you might as well say it directly." Liu Bowen was a strange person who would be a god in later generations, so he naturally guessed Liu Xiu's thoughts.

"That Wang Lin is a strong opponent, to put it bluntly, if I attack a strong city like Kunyang, I will use skill, not strong." Liu Xiu thought about it empathically.

"The lord has a point. If there is an enemy's internal response in the city, come to the inside and the outside..."Liu Bowen was deducing, after all, this product is known as a half-immortal, which is more mysterious than Zhuge Liang.

"Then there's another possibility." Liu Bowen is arranging hexagrams, trying to determine the good and bad of things through hexagrams.

"Sir won't want to go with me, will he?" Liu Xiu smiled dumbly.

"I'll count 123, let's talk about it together." Liu Bowen had light in his eyes.

"Tunnel siege!" The two almost blurted out.

Digging tunnels is a stealthy way that can take a long time, but once you get inside the city, you can break through the enemy's fortress from the inside without even noticing.

Moreover, this offensive method is difficult to carry out targeted defense, in front of the enemy's appearance, no one knows where the tunnel exit comes from, it may be in a farmhouse, it may be in a sparsely populated place, and it is more likely to be in a busy place, because the noise of people can cover up the noise generated when digging a hole.

"It's hard to do, sir, do you have a good plan?" Liu Xiu had no choice but to sigh.

Conspiracy is a trick played by villains, and the real master is the best at yang conspiracy, just like the siege method of tunnel warfare, you know he will use this method, but you have nothing to do.

A Kunyang city is not big, it is not small, who can do 24 hours without eating, sleeping, and staring, who has the energy to cover every place and every corner of the city.

This is the conspiracy, and there is often no solution.

"It's not completely impossible." Liu Bowen smiled indifferently.

Only a top wise man like Liu Bowen in this world can be calm and calm in the face of the biggest crisis.

"Please sir." Liu Xiuzhen regards Liu Bowen as his teacher.

"Generally speaking, digging tunnels is a big project, time-consuming, costing manpower, material and financial resources, from the other party's point of view, it is unlikely to dig the tunnel too long, it is estimated that it extends from the tunnel mouth to within 1 or 2 kilometers in the city, and the tunnel exit, must be selected in some special places, what is the specific place, one or two sentences are not clear." Liu Bowen pondered for a while and said.

"Sir, do you think this will work?" After all, Liu Xiu came from later generations and can be said to be well-informed.

"Within one or two kilometers of the city wall in the city, it is best to have people patrol 24 hours a day, and set up a fixed checkpoint at intervals, and a sentry officer will stand guard to convey the news in time in case of emergency." Liu Xiu said it very carefully and reasonably.

"I think it's possible. Of course, in order to ensure that nothing goes wrong, it does not hurt to let the patrol people walk a few more steps. Liu Bowen added.

"Then the gentleman will make arrangements immediately." Liu Xiu nodded and said.

Under Liu Bowen's personal supervision and arrangement, a professional patrol team was quickly established.

Day shift from 6:00 a.m. to 18:00 p.m., shifts change every two hours; The evening shift is from 18:00 to 6:00 in the morning, and changes every two hours.

The patrol range is less than 2 km.

In addition to forming patrol teams, fixed checkpoints are set up at various streets, alleys and other locations, and special personnel are responsible for standing guard, which is changed every 12 hours.

Liu Bowen also demanded that all grassroots officials and military officers come to inspect on a regular basis and report any emergencies in a timely manner.

......

In the next fifteen days, Wang Lin only let a small group of troops take turns to attack the city, and did not make any major moves.

But today, Wang Lin went against the norm and ordered the army to storm Kunyang, fighting harder than before.

I can see that Ren Guang and the others will stand on end.

This guy is so good, what a madness!

Wave after wave of enemies, fearless to the death, attacked the city, and fought hand-to-hand bloody battles with the Han army.

I saw blood splashing, and stumps and broken bodies everywhere.

There are enemies, and there are Han troops.

The war was brutal and fought fiercely.

......

A tunnel with a diameter of 1.6 meters and a length of 1.4 kilometers was opened underground, leading directly to Kunyang City.

"Boss, the exit is a green building." The guide took advantage of the bustle of the day to sneak into the city through the tunnels.

"Damn, that's bad luck!" The engineer commander scolded and went to report the situation.

Wang Lin was overjoyed when he heard this, and praised him fiercely.

Later, he made Gao Chong a general, and commanded 50,000 troops to enter the passage at night.

All this is under the control of Wang Lin.

"Liu Xiu, what are you fighting with me!" Wang Lin imagined that Liu Xiu was defeated and captured, and kowtowed to beg for mercy in order to survive.

Xiu'er, my brother won't kill you, he will only let you surrender to me!

Wang Lin YY, thinking of the proudness, laughed out loud: Hahaha...
