Looking at the team carrying six mortars, they were divided into three groups and left the abandoned houses one after another. As tonight's commander, Hu Biao also has a more important task. The first explosion of tonight's operation will be initiated by Hu Biao himself.

Bypassing the Japanese army's guard post at the wharf and port, Hu Biao, who was standing by the river, began to warm up. Next, Hu Biao needs to dive into the water and dive next to the ship anchored in the harbor. When you go into the water in this kind of weather, you can imagine how cold it will be.

If he didn't warm up in advance, Hu Biao was also worried that it would be the same as the previous time in Shanghai. Feeling his body slowly heating up, Hu Biao poured two sips of high liquor before going into the water. After suffering a loss, Hu Biao will naturally remember this lesson.

Although he knew that Hu Biao was going to sneak into the port and blow up the river ships parked in the harbor by the little devils. But Hu Minyi and others were still ordered by Hu Biao, and no one was allowed to go over. When Hu Biao returns, he will join them in attacking the dock warehouse.

Taking off the cotton clothes and pants that were in the way, Hu Biao quietly slipped into the icy river water. Even if he was mentally prepared, when his body was soaked in the river water, Hu Biao couldn't help but bared his teeth and said: "Damn, this river water is really cold!" ”

Hu Biao, who had winter swimming experience in his previous life, adapted to the river for a while, confirmed that there was nothing wrong with his body, looked at the ship anchored in front of him, took a deep breath and dived into the water. On the dock side, searchlights patrol the river from time to time.

To Hu Biao's surprise, the Japanese army moored five river ships in the port, but did not arrange patrol boats, and only set up searchlights on the high part of the pier. It can also be seen from this arrangement that the Japanese army was not at all worried about the surprise attack of the national warships from the river.

Just think about the embarrassment of the Republic of China Navy almost existing in name only, it is understandable that the little devil will be so relieved. In the final analysis, today's national government can compete with the little devils except for the army, and the navy has basically withdrawn from the combat sequence.

As for the other air forces, they can only occasionally compete with the little devils. If you want to be like a little devil and provide air force support to the army units, it is not very possible at all. It is a rare opportunity to blow up the ship, and Hu Biao naturally will not miss it.

At present, the several inland river ships anchored in the port are all sharp weapons used by the little devils to control the Yangtze River. If it is blown up and sunk, it is believed that within a short time, this port will also be abandoned by the Japanese army. A ship that is sunk will inevitably block the waterway of the port.

In order to prevent the little devil from attacking Nanjing along the Yangtze River, the only remaining ships of the Republic of China Navy sank themselves in the Jiangyin fortress, and the combat plan of the little devil advancing by land and water had to be completely abandoned. But this kind of behavior is indeed too tragic.

In contrast, now the little devil has the strongest naval force in Asia, and has basically completed the blockade of the Chinese sea outlet. Even in the inland waters, the Japanese army still ran rampant. These inland river ships are where the confidence of the Japanese army lies.

But for Hu Biao, who came to Runzhou City this time, he felt that these ships were an eyesore. If these ships are not blown up, Hu Biao will feel uncomfortable. Blowing up and sinking these ships, I believe that the little devils will be distressed and sad for a while!

It is Hu Biao's responsibility and obligation to fight behind enemy lines and constantly block and create trouble for the little devils!

Hu Biao, who scuba for a while, then surfaced to change his breath and continued to dive towards the ship, did not take long to swim to the side of a ship with the largest tonnage. According to the situation of prior reconnaissance, the troops on board the ships were stationed in the barracks of the city.

The Japanese army, which had not yet formed a river defense unit in the south, was bound to strengthen its control of the Yangtze River in the future in order to control this important water passage. These ships and troops were prepared by the Japanese army to control the waterway of the Yangtze River.

Swimming to the side of the ship, which could not be illuminated by the searchlight, Hu Biao, who could finally breathe heavily, took out a homemade flying claw from his personal space. After taking a deep breath, throw it onto the ship in front of you and hold it firmly in place.

Following the rope hanging down from the flying claws, Hu Biao climbed the rope. If the little devil also arranged for a sentry to be on duty on the ship, maybe Hu Biao wanted to get on the ship tonight, and it would become relatively troublesome. It's a pity that the little devil didn't!

Hu Biao, who successfully boarded the ship, felt the coolness of the cold wind and drizzle caressing his body, and couldn't help but say: "Damn, doing this work in this weather, it's really cold!" Hurry up and finish early! ”

Hu Biao, who muttered a few words, stood on the river ship of the little devil, looking at the searchlights on the dock that strafed the river, and was still very careful to hide his figure. After a closer look, Hu Biao quickly entered the ship's internal engine room.

Looking at the neatly stacked naval shells on the ship, Hu Biao showed a sneer and said: "These little devils, they are really relieved!" ”

The alcohol lamp that had been purchased earlier was lit, and then the fuse was tied to a hemp rope. According to the conclusion of Hu Biao's experiment in advance, under the same height and heat burning, the alcohol lamp burned the hemp rope within an hour.

Without the timing device of later generations, Hu Biao could only use equipment such as alcohol lamps and hemp rope to create a device for delaying the detonation. Even if he knew that this might not be accurate, after the experiment, Hu Biao would be more assured.

Looking at the lit alcohol lamp, he was slowly but surely fighting against the hemp rope. Hu Biao arranged a delayed detonation device in the inner engine room and ammunition depot. In this case, it is equivalent to double insurance.

Regardless of the detonation of the explosive device, the ship will inevitably be blown up and sunk. If both of them are detonated, even if the little devil carries out the shipwreck salvage, the ship will completely lose the possibility of repair.

"It's only an hour, and there are still three ships to blow up, so you have to be quick! Finish the day, next! ”

The detonation device placed in the inner engine room, Hu Biao gave a heavy artillery shell for heavy artillery. As for the ammunition depot, the ship's own shells are stacked next to it. Once the explosion is launched, I believe that the scene will be spectacular.

Putting away the flying claws that had been thrown on the boat to fix, Hu Biao found a fixed object again, tied the rope and pulled the knotted end, and lowered the rope into the river again. Untying the knot begins with force, and the rope is quickly retracted.

Still using the same method, Hu Biao kept taking out the detonation tools he had prepared before from his personal space, and found some useful weapons and ammunition from the little devil's ship warehouse and stored them in his personal space.

What interested Hu Biao the most, and even did not hesitate to find tools from the ships to disassemble, was the single-unit anti-aircraft machine gun installed on the two ships. This machine gun is used alone for air defense, and the effect is only afraid that it will not be too good.

It can be used to fight the thin-skinned tank of the little devil, and it is also used to shoot flat shots, which is naturally powerful. Seeing that Hunter was happy, and there were still a lot of machine gun bullets stored on the ship, Hu Biao naturally wanted to sell some strength to dismantle them.

Although Hu Biao was not very clear about the model of this anti-aircraft machine gun, he knew that this machine gun was also a foreign anti-aircraft machine gun copied by the Japanese army. Installed on ships, it can not only play the role of air defense, but also can be used as a defense of ships.

Looking at the several anti-aircraft machine guns that were successfully disassembled, Hu Biao also secretly rejoiced: "Little devil, good person!" In addition to blowing up the ship, such a big gift is also given for free. I'm embarrassed if I don't treat them well! ”

If the little devil hears Hu Biao's self-talk, it is estimated that he will also be angry and vomit blood. Hu Biao's style at the moment is obviously 'cheap and good'. The problem is that Hu Biao is the only one on the ship now, and the little devil can't hear it.

Knowing that there should not be much left until the time of the explosion, he had to rush back to meet Hu Minyi and others, and Hu Biao did not stay on the ship for long. Even if there are many weapons installed on the ship, he is greedy, but he still can't remove them.

Even for these anti-aircraft machine guns, Hu Biao took a lot of effort, and the little devil was not completely welded to death when he installed the machine guns. In this way, Hu Biao picked up a leak and took the opportunity to take these anti-aircraft machine guns.

Diving into the river again, Hu Biao swam in the same way as before, and avoided the searchlight of the little devil in the way of diving, and returned to the shore safely. Find a dry cloth and wipe the river water off your body.

Putting on cotton clothes and pants again, Hu Biao breathed a sigh of relief and said: "After freezing, I know the preciousness of clothes!" ”

After confirming that there was no problem, he glanced back at the ship that was still moored in the harbor and swaying gently with the waves of the river, Hu Biao also smiled and said, "I'm ready to watch the fireworks!" Such an expensive fireworks display is rare even in future generations! ”

Even if the little devil has a large number of ships at this stage, the cost of each of these ships that have been put into service is not cheap. As soon as it was bombed this time, these four inland river ships anchored in Runzhou Port could only be used as scrap metal for refurnace even if they were salvaged.

The loss of four such inland river ships at one time will be shocking and angry to the little devils! But for Hu Biao, if it weren't for the fact that these four ships were eye-catching and valuable, he would not have personally launched the water to freeze and bomb the ship.

Braving the icy and biting river water, he personally infiltrated and installed explosive devices, and the results of the battle naturally had to be paid by Hu Biao! When the ships were detonated one after another, Hu Biao believed that the entire people in Runzhou City would have complete insomnia tonight!
