"Quick! Fast! Hurry up! Retreat all into the retreat channel! Speed up and retreat! Liu Hong shouted loudly. Under the command of Liu Hong, the soldiers passed through the workshops and warehouses of the explosives factory along the tunnel, and entered the retreat passage one by one.

As I said before, there are two retreat channels for the old kiln factory, and the one that Liu Hong deliberately let the little devil find before is only one of them, and the other one is longer, and this tunnel exit is also more hidden, and it is far away from that tunnel exit, so it was not discovered by the little devil, and this passage has also become the last channel for the retreat of the martial arts team.

After everyone entered the retreat channel, they did not stop, but continued to flee into the distance, and the warriors did not dare to delay, and fled as fast as they could.

At the same time, the murderous little devil rushed into the house, and found more than a dozen tunnel entrances that were too late to cover, the little devil rushed over and fired a few shots into the tunnel, but the martial arts team had already run away, and the tunnel was not straight, they shot at the tunnel entrance, naturally there was no effect.

"Your Excellency Shaozo, those hateful people have all run into the tunnels, what should we do now? Do you want to go down and chase it! Captain Kitada asked with a frown.

Nobuhiko Kamiya glanced at one of the tunnel entrances, frowned and asked, "How many tunnel entrances are there in total?" ”

"About a dozen." Captain Kitada replied.

Kamiya Nobuhiko lowered his head and glanced at it, and couldn't help frowning and said: "The earth eight roads are extremely cunning, and they have been operating here for many years, they must have a back hand, the terrain in the tunnel is narrow, and it is difficult for the imperial army to enter it, but it will give these hateful earth eight roads a chance to take advantage of." After suffering the loss last time, Kamiya Nobuhiko naturally didn't dare to go down into the tunnel easily.

Captain Kitada frowned deeply and asked, "What should I do, Tuba Road has been operating here for many years, and the tunnels below are intricate, so it really shouldn't be easy to go down." It's just that these dirt roads must be prepared, if there is enough food and water in the tunnel, they can hide in the tunnel for a long time and not come out, and we have no way to deal with them. ”

"Humph!" Nobuhiko Kamiya snorted coldly and said, "If they don't come out, can't we find a way to force them out?" ”

Captain Kitada hurriedly asked, "I don't know what your Excellency's plan is?" ”

Nobuhiko Kamiya frowned and thought about it, and said with a sneer: "Didn't they hide in the tunnel and refuse to come out?" Then we will return to others in their own way. ”

Captain Kitada frowned and said, "I am humble and dull, and I hope that His Excellency Shaozuo will advise." ”

"Smoked! Didn't they hide in the tunnels and refuse to come out? Then let them all suffocate inside! Immediately ordered people to cut fresh grass and light up these holes, so that a large amount of smoke will be generated, and if we block the holes, all this smoke will pour into the tunnels. Their tunnels are very long, and there will definitely be exhaust holes, where there is smoke, and then we will use the same method, light the fresh grass to block these exhaust holes, so that more smoke will pour into the tunnels, and when we plug all the exhaust holes, the whole tunnel will be filled with smoke, and then I will see where these abominable dirt roads can hide. Nobuhiko Kamiya said through gritted teeth.

"Your Excellency Shao Zuo is wise, and you will arrange someone to do it." Captain Kitada hurriedly responded, and then began to order people to cut weeds nearby according to Kamiya Nobuhiko's method.

At this moment, a violent explosion suddenly sounded in the distance, and Nobuhiko Kamiya's face changed slightly, and he found that the site of the explosion was about a kilometer away from the old kiln factory, and a cloud of dust rose on the ground after the explosion.

Then the second explosion sounded, this time the explosion site was only seven or eight hundred meters away from the old kiln factory, and soon the third explosion sounded, this time the explosion site was only five hundred meters away from the old kiln factory.

"Baga Ya Road! We were fooled! Evacuate~! Nobuhiko Kamiya's face changed dramatically, and he suddenly shouted loudly, then turned around and ran.

At this time, the fourth explosion sounded, and the explosion point was only two or three hundred meters away from the old kiln factory, and after the explosion, the ground collapsed, forming a large crater.

At this time, the Japanese puppet soldiers in the old kiln factory also realized that something was wrong, and heard Kamiya Nobuhiko's reminder, and suddenly became a mess, one by one they were frightened and fled for their lives.

Nobuhiko Kamiya was the first to realize the danger, and this old devil was also very shrewd, knowing that it was too late to run out, so he turned around and ran onto the roof, climbed the embankment with a roll, and ran quickly towards the river.

"Boom~!" A violent explosion suddenly sounded, and it can be clearly seen from a distance that a huge mushroom cloud rose in the old kiln factory in an instant, and the earth torn by the firelight came out of the ground, and the houses in the old kiln factory collapsed instantly, and the brick and tile fragments were blown up and flew around, and the dust that was blown up went straight to the sky, rushing out of the ground at least 100 meters high.

It turned out that Liu Hong had stored thousands of catties of explosives and thousands of catties of sulfur, saltpeter charcoal and other raw materials for making bombs in the warehouse of the explosives factory before Liu Hong placed them in the tunnels below the old kiln factory, so many flammable and explosive materials were detonated at the same time, and its power can be imagined, the old kiln factory was destroyed instantly, and more than 200 enemies who attacked the old kiln factory were also swallowed up in an instant.

In order to avoid the shock wave generated by the violent explosion from impacting the martial arts team in the tunnel, Liu Hong did not directly detonate the explosives under the old kiln factory, but gradually detonated the four explosion points from a distance, so that the four sections of the tunnel were completely blown up, so even if the shock wave generated by the explosion was large, it would not rush into the narrow tunnel and cause an impact on the martial arts team inside.

However, in this way, there was a time difference, so that Kamiya Nobuhiko realized the danger in advance, this old devil's skills are also quite agile, and he quickly ran into the river, as soon as the explosion sounded, the old devil immediately sank into the river, but he still underestimated the power of the explosion, even if Kamiya Nobuhiko hid in the water, he was still shocked to the point that a stream of blood spurted out of his mouth, and a trace of blood flowed out of his ears and nose, and he lost consciousness in an instant, and slowly floated away along the river.

The smoke of gunpowder was gradually blown away by the wind, and the old kiln factory had completely disappeared, forming a huge pit with a diameter of more than 100 meters in place, which was still burning with raging flames, and a large amount of river water poured in, and the flames were gradually flooded by the river, forming a huge puddle.
