In fact, not to mention Japan, even the United States was no different. What's more, originally based on the scientific and technological foundation of the United States, it would not have taken too long to start with the first-generation cloudburst bomb step by step, but the United States was misled by the research direction of the third-generation cloudburst bomb that was ahead of the times, and as a result, the research progress of the cloudburst bomb was much slower than in history, but this is a story for later

Having said that, the regiment commander's concern is not entirely unreasonable, but Hu Weidong has already come up with countermeasures over the years, and the fully armored troops that meet the conditions of the "three defenses" in the field can minimize the lethality of cloud burst bombs, while in tunnels and other fortifications, they can only rely on multiple closed gates to shield the shock wave and negative oxygen effect (it is also possible to change the tunnel network to short tunnels that are independent of each other, but then the power of tunnel warfare will be greatly reduced, and it may not necessarily be cost-effective). ）。 Both of these methods require strong national strength as the foundation, but by the time the powers are equipped with a large number of cloud burst bombs, China's nuclear weapons should have already been developed, right? Again, "it is the people, not one or two new weapons, that decide the outcome of a war." Hu Weidong can't think of a cheap and efficient way now, and it may not be that no one among China's hundreds of millions of military and civilians will think of it in the future. And even if there really isn't a good way, wouldn't the enemy be just as good as our cloudburst bombs? It must be known that according to the current momentum of China's development, it is not impossible to squeeze into the top three of shijie twenty or even thirty or forty years earlier than in history, not to mention that you have powerful weapons, how can it be better than nothing, right?

Due to the limited time, the tunnels dug by the devils in Jinan City were not very long, even though the number of individual cloud burst bombs brought by the 15th Army for actual combat testing this time was not very large. It is also enough to eliminate the devils who are ambushed in the tunnels and shoot black guns. Moreover, the cloud burst bomb has a miraculous effect on any kind of fortification in the world at present, so the devil positions that the officers and men of the 15th Army could only take with great effort are now taken one after another without blood, and the devils who can still resist are also frightened by this mysterious new weapon, even if the commander Itagaki Seishiro personally supervises the battle, there are still people in the Japanese army in Jinan who have begun to surrender one after another. When the 9th Infantry Brigade of the 5th Division of the Japanese Army, which was the first to return from the mountains and was in a hurry to rescue Jinan, was also completely annihilated by the main force of the 15th Army, which had already prepared for the siege and reinforcements, the Japanese troops in Jinan City lost their confidence. Seishiro Itagaki, who could only watch his army fall to the ground despite all his might, sighed and slowly drew his saber

"Your Excellency, General. The empire still needs you! Seeing this, the adjutant said urgently.

"If you break through from the beginning, maybe there is hope. Now the 15th Army of China has surrounded the city of Jinan like an iron barrel, and it is impossible to break through. Seishiro Itagaki carefully wiped the knife in his hand. While replying, "What's more, Itagaki has already left the army once, and I don't want to leave it a second time."

Perhaps the fear of the unknown was too great, and Itagaki's seppuku did not arouse the courage of many of his subordinates, and no less than 10,000 of the 20,000 Japanese troops in Jinan surrendered before the 15th Army attacked the city. However, the order that Itagaki issued to the hundreds of thousands of Japanese troops who were sweeping into the mountains before seppuku, and a telegram he sent directly to the headquarters of the Central China Front in the past of his superiors, almost succeeded in reversing the situation of the Anti-Japanese War

"Didn't go north to rescue Jinan, but chose to go south to join the hundreds of thousands of Japanese troops in southern Lunan?" Hu Weidong made this judgment after receiving a telegram from a reconnaissance plane and a report from the Shandong base area. I couldn't help frowning slightly. Originally, if these Japanese troops left the base area and went north to Jinan, due to the restrictions of the mountainous terrain, they would inevitably be divided into several groups, and their strength would have been inferior to that of the 15th Army, and they would not be opponents if they were divided into troops. In this way, the 15th Army can eat no less than 100,000 devils in one breath without paying too much price, but who knows that the devils suddenly gave up the rescue and went south to join the Japanese army in southern Lunan, and the two armies combined exceeded 250,000 people, which is obviously not something that Hu Weidong can confront head-on with the more than 100,000 people at hand, and it is no wonder that Hu Weidong feels depressed. …,

"It's indeed a wise choice, it should be Itagaki's last life, right? Otherwise, they would have known that I had dug a hole. They did not dare not save it. Itagaki this guy is really not simple, he has disgusted us before, and he can't imagine that he will block us if he dies", Hu Weidong thought of this, but laughed instead, "But after all, I am the one who wins!" And do you think that's all I have to offer? Itagaki ah, itagaki keep your eyes open in hell! ”

Next, Hu Weidong took advantage of the opportunity of the Japanese army in Shandong to retreat south, and divided his troops to attack everywhere at a very fast speed, and captured many cities and dozens of county towns that the Japanese army had actually abandoned in just a dozen days, so that the scale of the Shandong base area expanded rapidly, with an area of more than half of Shandong, and the population exceeded 24 million (in 1931, Shandong had a population of 37 million, and in the following years, the situation in Shandong was relatively stable, and its own population growth and the influx of refugees from other provinces, even though it decreased after the outbreak of the Anti-Japanese War, At this time, the population of the province should also be 40 million to 45 million. ), surpassing any of the other base areas of the Red Party, including the Central Plains Border Region

However, the more than 100,000 local troops and militia guerrillas in the Shandong base area had already been tempered by the flames of war, and after joining up with the main force of the 15 th Army, they were quickly armed with a large amount of weapons and ammunition, and the strength in Hu Weidong's hands suddenly increased to more than 200,000, of which there were 180,000 field troops alone (if the number of new recruits exceeded one-third, the combat effectiveness of the troops would drop by a large margin, and the base areas also needed to retain some troops, so Hu Weidong only selected 70,000 or 80,000 troops from the armed forces in the base areas. Even if it is a decisive battle with the 200,000 or 300,000 Japanese troops in Lunan, it may not necessarily lose.

In addition, even Itagaki Seishiro was a little negligent, he asked the Japanese army in Luzhong to directly give up a large amount of territory and retreat south, although it effectively preserved its strength, but also lost a number of airfields, for a time the Japanese army in Shandong only had two airfields available, Yantai and Qingdao, even if it was stuffed with planes, how many planes could there be? After Hu Weidong realized this, he immediately and decisively demanded that the two divisions of the air force immediately be stationed in Jinan and other airfields that had just been snatched from the devils, thus seizing air supremacy in the Shandong battlefield at once. The only thing that made him a little regretful was that because the devil took the initiative to abandon the airport, the 15 th Army basically failed to capture a few planes this time, but four Japanese 97 transport planes still fell into the hands of the 15 th Army, although the performance of this transport aircraft is simply miserable, but it is always more suitable for air transport than bombers, and it also inherits the traditional advantages of Japanese products - fuel economy (you are welcome to your support, is my biggest motivation. )
