Side, Nicholas. Cage looked at Kane and laughed:

"Haha, Karn, they all say that you are the god of war, after drilling the dog hole this time, you can be named the 'God of War in the dog hole' in the future! Ha ha! ”

Karn was annoyed and tried to go up and beat Cage. However, although Cage can't beat Kane, he is very fast, and it is difficult for Karn to catch up with him.

The two were chasing, and Marin coughed:

"Nicholas, don't be happy, because, this time through the sewers to attack the city, in addition to Karn, you and your special forces must be the vanguard!"

The sewer hole is too small for one person to climb into. Even if you open the iron gate, you can only climb in one by one. Therefore, there are certainly not many people who entered the city in the early days. With a small number of people, it is easy to be suppressed back by the enemy. As long as the enemy repels the first strikers who burrow into the city, and then sends heavy troops to guard the sewers, they will not be able to attack. Because, if you have to climb into the dog hole, as soon as you enter, I am afraid that you will face countless swords......

Therefore, for a fierce player like Karn to take the lead in drilling the dog hole, it is a must. Only Karn could withstand the first wave of counterattack by the enemy guarding the sewers.

But Karn alone could withstand the small group of men guarding the sewers, but it was difficult for him to withstand the large number of enemy men. After all, this sewer exit is not far from the Northeast City Gate. Once the warning is given, a large number of enemy troops will definitely be killed. Even if Karn was strong in martial arts, he could fight ten at a time. Wearing full-body plate armor and not being afraid of swords, you can fight up to 20. But if the enemy came in hundreds or thousands, Karn would also kneel.

So, the warriors who drilled the dog hole behind Karn must definitely be elite. For example, dozens of special forces fighters led by Cage are the best candidates for the first batch of people to enter the city. With the help of these dozens of men, and the narrow streets of the city, Karn was able to hold back the enemy's army from counterattacking. Then, wait for more fighters to crawl in from the dog hole......

……

Of course, the above is Marin's plan. But first, he had to get someone to open the iron door of the dog hole at the sewer exit......

It is said to be an iron gate, but it is not a city gate made of a whole piece of iron like a city gate. Why? Because, this is the sewer exit. Sewage and debris have to flow out. If the iron gate is made into a single piece, how will sewage and debris flow out? Does it stink in the city?

Therefore, the iron gate of the sewer is actually very similar to the iron fence gate of later generations. This is the only way to keep the sewer mouth safe from being drilled into by the enemy, and to allow sewage and debris to pass through and out of the city.

In order to facilitate the solution of this iron fence gate, Ma Lin even wore a mask and personally inspected this iron fence gate in the middle of the night. Marin found that the steel bars of the iron fence gate, although thick, were much easier to deal with than the whole iron gate used for the city gate. As long as the 8 steel bars on the iron fence gate are corroded, the iron fence gate can be opened.

Moreover, Marin observed that the enemy would not come to observe the iron fence gate in the middle of the night. Because, the smell here is really bad.

In this era, Europeans were not like the Ming Dynasty, where peasants specially pushed dung trucks into the city to collect manure as fertilizer in the fields. Therefore, most of the feces in the city are discharged out of the city through sewers. This shows how smelly it really is at the sewer exit.

If it were summer, it would stink so much that it would make people faint. Fortunately, it's winter, and the smell has dropped a lot. However, it's hard to stay here without a mask.

Through the observation through the iron fence gate, Marin found that the defenders inside, about ten meters away, deliberately avoided the stinky ditch. However, if there is a sound from the iron door, someone will still come to check it. For example, Marin deliberately knocked on the iron fence gate, and soon the defenders came to check it out.

It's just that the next way Marin asked people to get this iron fence gate really didn't make any sound, and it didn't alarm any of the defenders......

Marin selected a few reliable special forces fighters, put on masks, each holding a can of paint ingredients (mainly adhesive ingredients), a few brushes, and took turns to lurk at the door of the sewer dog hole in the middle of the night, lightly dipping the brush in dilute sulfuric acid and brushing it on the steel bars on the iron fence gate......

With gentle movements and attentive expressions, they repeatedly brushed back and forth on selected nodes with brushes dipped in dilute sulfuric acid. In that scene, those who don't understand it think that they are brushing the sauce on the barbecue on the bamboo skewers...... There was a faint background music in the air - "Hee-hee, hee-hee, oh-oh......"

……

The dilute sulfuric acid, which was added to the paint binder, did not flow down as easily as before, but stuck to the steel bar and flowed down very slowly. In this way, the dilute sulfuric acid can have enough contact time with the steel bars of the doghole iron fence gate.

But despite this, several members of the special forces took turns to fight, and it took several nights of work to finally corrode and break several important steel bars...... Moreover, because they didn't make any noise, they weren't discovered by the negligent defenders...... Mainly, the defenders were reluctant to approach and judged the threat only by their voices. After all, according to common sense, if you want to destroy the iron fence gate of the sewer exit, the sound should generally be earth-shattering......

……

Marin was thrilled to learn that the iron fence gate of the Dog Cave in the sewers of Siena City had finally been corroded. Then, turning his gaze to Karn and Cage, who looked unnatural, he smiled:

"It's up to you, if you can withstand the enemy's counterattack and lead the army to open the Northeast City Gate from the inside, you will be the first merit!"

……

Karn and Cage didn't talk nonsense, and dozens of special forces fighters began to change their full-body plate armor......

The mountain infantry corps led by Marin originally did not carry plate armor, but only rhinoceros leather armor and wood chip armor. After all, it is inconvenient to go over the mountains with plate armor. However, Saqqara's Fourth Legion brought it. The Fourth Legion took the main road, and naturally was not afraid to carry baggage and plate armor.

Considering the danger he might face if he got through the dog hole, Marlin arranged for someone to go to Saqqara and get dozens of sets of plate armor for Karn, Cage, and dozens of special forces fighters to change into. In this way, after they enter, they are not afraid of the enemy's sword, and they can more easily withstand the counterattack of the enemy army, so as to wait for more people to climb into the dog hole......

……

While Karn and the others were wearing plate armor and preparing, Saqqara's Fourth Army launched a large-scale feint attack in the direction of the Northwest Gate in advance to attract the enemy defenders to converge in the direction of the Northwest Gate to relieve the pressure on the side of the Northeast Gate.

When he heard the shouting and killing sound coming from the direction of the northwest gate, Marin looked at the time and nodded:

"Alright, Karn, let's go! Remember, after defeating the counterattack of the retreating enemy, quickly lead people to capture the tower of the northeast gate. The city gate must be full of debris at this time, so don't worry about it. As long as the tower is occupied, our large army can set up ladders to climb up. Finally, we occupy the city gate hole and slowly clean the masonry and debris in the city gate hole! ”

"Understood!" Karn, Cage, and dozens of Special Forces fighters replied in unison.

Then, Karn, the "Devil Muscle Man", took the lead, carrying a mace, and touched the iron fence of the Dog Cave in the sewers......

At this time, after the operation of several special forces fighters brushing sauce, the steel bars on the iron fence gate of the sewer dog hole were already only a trace of it could fall off. However, Marin had not asked them to break the steel bars that were about to fall. Mainly, it is afraid that the enemy army will find out. After all, although the enemy is reluctant to approach this sewer dog hole, they sometimes take a look from a distance. Therefore, when Marin asked his subordinates to corrode the 8 steel bars, they did not corrode and break, but corroded so that only a trace remained, and as long as they were lightly broken, they would break......

Karn made his way to the iron fence door of the sewer dog hole, set the mace aside, and then easily broke all eight steel bars that were still connected to the iron fence door in one fell swoop. Then, with a quick lift, the mace was taken into the dog's hole and into the city of Siena......
