Hu Weidong, who was worried about going on like this, finally made up his mind, "It seems that only by destroying all the more than 400,000 Japanese troops surrounded by the encirclement at the fastest speed at all costs, so that the great powers can see that Japan is bound to fail, and the following work can be carried out!" ”

After receiving a telegram from the General Headquarters of the 15th Group Army, the Central Committee and Taizu quickly approved it, but considering that compared with Kaifeng, the Japanese army occupied Xuzhou earlier, and had a long-term confrontation with the main force of the 15th Group Army, the defense system of Xuzhou was more complete and the total strength was larger, and the Eighth Route Army had been encircling Kaifeng for a period of time, and its continuous attacks and harassment had exhausted the enemy in Kaifeng, so the Central Committee decided to first use the Eighth Route Army as the main force to annihilate more than 100,000 devils in Kaifeng with the assistance of the 15th Group Army, and then combine the strength of the two major group armies. The more than 200,000 Japanese troops in Xuzhou were all wiped out, drawing a successful end to the Central Plains Conference that Shijie had attracted attention.

Originally, with the idea of Lin Biao, the commander of the 27th Army who is currently actually commanding the Eighth Route Army, Kaifeng would have to be surrounded for at least another month before launching a full-scale attack, but Taizu, who was worried that he would disobey his orders, sent him three telegrams in a row, and Lin Biao, who had no choice, had to resolutely obey the order. Fortunately, the central authorities demanded that the 15th Group Army dispatch all heavy artillery with a caliber of more than 105mm to support the Eighth Route Army, which gave him a little more confidence in his heart

At the pre-war preparation meeting, a certain division commander asked the young commander which unit should be the main attack and which unit should feint in this battle, but the commander of the army, who has always been known for his skillful fighting, glared at him fiercely and said sharply, "Our army has one million elite soldiers, as well as thousands of artillery pieces and hundreds of planes to help fight against hundreds of thousands of devils." Do you need to divide any main attack feints? Beat me to death! ”

This order quickly spread throughout the army, greatly boosting the morale of the Eighth Route Army, which had originally added a large number of new recruits. These people were somewhat war-afraid, but after hearing Lin Biao's deliberately exaggerated comparison of the strength of the two sides, their confidence increased greatly. On the other hand, Mr. Lin, who has always been good at fighting skillfully, was not carried away by the idea of rushing to win. On the contrary, a strong attack from all sides is exactly what Okamura Ningji, the commander of the Japanese army in Kaifeng, is most afraid of. Because the Japanese army in Kaifeng at this time was already exhausted after a long period of harassment by the Eighth Route Army, and now the Eighth Route Army launched a fierce attack from all directions outside Kaifeng. On the one hand, the Japanese army lacked a sufficient number of reserves to deal with various emergencies, and on the other hand, it meant that the devils could not rely on rotation to get a chance to rest, while the attacking troops of the Eighth Route Army with strong strength could divide their forces into three parts and attack in turn without stopping, but after two or three days, the devils, who were known for their tenacity, could not hold on. There are even those who go crazy because of severe lack of sleep, and who never wake up when they fall asleep

It is worth mentioning that although the necessary "single-base fuel explosives" have not yet been industrialized (Note 1), even the individual soldier cloud burst bombs with a small charge are currently only more than 1,000 pieces (the charge of one is only 50 or 60 grams, that is, more than 1 tael, and more than 1,000 individual soldier cloud burst bombs only need more than 100 catties). Even if it is prepared by laboratory means, it is enough. In the Battle of Jinan, the individual soldier cloud burst bomb was used again on the battlefield to deal with the devils hiding in semi-enclosed fortifications such as cellars and hidden fortifications, and achieved amazing killing effects, killing and wounding more than 8,000 Japanese soldiers in total, and almost all of them were devils' elite soldiers. At the same time, due to the particularity of the lethal effect of cloud burst bombs, these devils died more and injured less, except for less than three hundred lucky people, the rest all died on the spot or were seriously injured and were all killed by the soldiers of the Eighth Route Army, in fact, this is also to help them get rid of it, burns all over the body are basically incurable in this era, rather than wailing to death in great pain, it is better to die more happily

Of course, this is also because there are too few individual cloud burst shells, so "good steel must be used on the blade", and it will only be used when encountering strong resistance that is difficult to work with conventional play, thus greatly improving the killing efficiency. And after a large number of troops are equipped, they will be used by any enemy they encounter, and they may even be used for fire suppression, and the killing efficiency will definitely drop a lot.

These more than 1,000 individual cloud burst shells not only killed a lot of enemies, but also caused the Japanese army to quickly break through those fortified positions that it thought could withstand the attack of the Eighth Route Army for a long time, which directly disrupted Okamura Ninji's deployment, and the Japanese troops in the city were even more panicked, and under the shouting and offensive of some Japanese officers and men sent by the 15th Group Army to participate in the siege battle, the morale of the army quickly collapsed. In order to avoid the enemy's enhanced version of the "Tearing Down the Wall and Siege Method" and directly eliminating his own headquarters, Okamura Ninji transferred his headquarters many times, which made the morale of the Japanese troops in the city even worse, and the various rumors spread by the Japanese propagandists with loudspeakers in Japanese were even more demagogic.

Under the double blow of spirit and body, in just three days, the Japanese army in the city that originally exceeded 100,000 was only 60,000 or 70,000 left, and it was divided into at least a dozen pieces and could not support each other, although the casualties of the Eighth Route Army at this time had exceeded 100,000, but Mr. Lin's original somewhat uneasy heart finally settled, and anyone could see that the devil no longer had any hope of turning the tables, and at this time, although the old devil Okamura Ningji was reasonable, But he still unexpectedly led the remnants of more than 60,000 people to surrender voluntarily

Note 1: So much so that Hu Weidong even wanted to replace the overly advanced third-generation cloudburst bomb with the old-fashioned first-generation cloudburst bomb, because the industrial production of ethylene oxide is relatively much easier, but the third-generation cloudburst bomb

Not only is the power nearly 10 times greater than that of a generation of cloudburst bombs, but also the production and use are more convenient, the safety in transportation and storage is also obviously superior, and the cost performance is far from comparable to a generation, and although the molecular structure of "single-base fuel explosives" is slightly complex, even under the technological conditions of this era, it is entirely possible to achieve industrial production, so Hu Weidong finally chose to trust the chemists of the Solid Fuel Research Institute, and those chemists did not disappoint him again, and finally achieved solid-state in April 1939" Single-base fuel explosives" are produced industrially. At the same time, with the help of concurrent engineering, the processing problem of the solid fuel column was solved less than a month later, making the development of the solid rocket possible, which was an unexpected surprise (to be continued). )
