After attacking fortified battles such as Wuhan and Lanfeng, the national * army was deeply impressed by the tenacity of the Japanese army in defending the city, and it can even be said that there was a huge psychological shadow, and it was generally not optimistic about attacking the fortifications.

For example, in the Battle of Lanfeng in May 1938, the 46th Division, which was reorganized by the Teaching Corps, charged at the defense position of Lanfeng City, and the three brigade commanders were either killed or wounded, and the 46th Division was almost completely annihilated. Later, the 64th Army conquered a small village of Luowangzhai, and the chief of staff actually sent a telegram to Commander Li Hansoul to congratulate him, saying that "the reconquest of lost territory since the Anti-Japanese War began with your army."

Yang Tianfeng simply agreed to send troops to help in the war, but he also attached great importance to the difficulties of attacking fortifications. Although he had a steel fist, a grenade launcher, and a shotgun, although he had planned to participate in this big battle for a long time, he still felt that there was not enough time and preparation.

But he also knew a long time ago that the arsenal was working overtime to produce weapons and ammunition that had already taken shape, and then put on new varieties, obviously it would not be able to achieve such production capacity.

During the eastward expansion, two armored vehicles, more than a dozen cars (not counting those that were later repaired) were captured, and a lot of gasoline and some repair tools were also captured in Sucheng. When he saw the stupid oil drum, an idea came to Yang Tianfeng's mind. When he returned to the base area, he recruited people to make it, and soon, the simple, easy-to-build, but properly used and powerful Thunder Cannon, or Flying Thunder Cannon, came into being.

Put the projectile pack, buffer plate, and explosive bag at the bottom of the gasoline drum upwards in turn, and pull the fire rope of the explosive bag to fix it on the gasoline barrel. When used, the projectile package is ignited, and the explosive package is thrown out through the buffer plate, and the explosive package is automatically ignited in flight due to the fire rope being fixed on the gasoline barrel.

It's that simple, although the accuracy is poor and the firing range is short, but in the battle of fortifications, it can greatly make up for the regret of the lack of heavy artillery in the national * army.

The oil drum was reinforced with an iron hoop, and the weight of the projectile, the weight and shape of the explosive pack, the angle of the oil drum cannon, and so on, after dozens of artillery tests, not only basically mastered the data, but also improved the firing range and accuracy. I don't dare to say that it is perfect, but it can still be used in actual combat.

It's up to you to win or lose. Yang Tianfeng sent him away, pacing back and forth in the house, and after thinking about it, he stomped his foot suddenly.

…………

Old boilers, motors, tires, etc., as well as metal pipe fittings that were unloaded from nowhere, were piled up in a warehouse, making Zhao Yurou and Hao Jiaqi a little dazed and clueless.

"These are materials that have just been purchased and seized, and according to the drawings, we are trying to build a cryogenic retort reactor." Yuan Chunlin habitually pushed down his glasses with his fingers, excited and a little forgiving, "It's a pity that I'm just a high school chemistry teacher, with limited knowledge, and I'm shy as the chief engineer, but I don't live up to my name, I'm really ashamed." ”

"Mr. Yuan is too humble." Zhao Yurou looked at Yuan Chunlin's copper-colored complexion, and suddenly felt that she should feel ashamed, under such difficult conditions, people did not lose confidence and were working hard.

"yes!" Hao Jiaqi nodded and said with deep sympathy: "Starting from scratch and starting from scratch, now it is a great achievement to be able to make coal coke and coal tar, and also to carry out rough distillation." It's just that we, who have low eyes and low hands, still need more advice from Mr. Yuan. ”

"Don't dare, don't dare." Yuan Chunlin waved his hand and said, "You two are highly talented students from the Department of Chemistry of Yan University. Although Chief Yang also appointed me as the chief engineer, it was just because I was older and more familiar with this small factory. In the future—"

"In the future, you will still be the chief engineer, and the two of us will definitely ask you for advice with an open mind." Zhao Yurou interrupted Yuan Chunlin with a smile, "Let's work together and make our own contributions to the Anti-Japanese War!" ”

"Mr. Yuan doesn't have to be polite, arrange work for the two of us!" Hao Jiaqi also helped.

Yuan Chunlin rubbed his black hands embarrassedly, thought for a while, and said: "The two of you will first familiarize yourself with the factory, and then read some data drawings to have a general understanding of the current situation of the factory and the work being done." ”

Zhao Yurou and Hao Jiaqi readily agreed, and under the guidance of a technician, they walked around the small factory before returning to the office and flipping through the materials.

With Yang Tianfeng's instructions, the two girls were naturally taken care of, and the office and dormitory were clean, bright, and even a little elegant.

After seeing the information, the two of them understood why Yuan Chunlin was so confident. The work of each stage has been clarified, not only with drawings but also with various data for testing and testing. It can be said that Yuan Chunlin and others are not moving forward in exploration, but rather following the rules and regulations, and are developing along the set path.

"In this way, the coal chemical plant is still very promising and promising." Hao Jiaqi took off her glasses, rubbed her sour eyes, and said, "Now it's mainly a problem with the equipment, but it's not that it can't be solved, just take more time." ”

"Well, although it is difficult to make self-made equipment, it is indeed not an insurmountable difficulty to have drawings to follow, put it together, or let the machine tools of the arsenal process some key parts." Zhao Yurou felt the same way, and remembered one thing again, "If Uncle Hao was here, how good it would be, he is a professor of chemistry!" ”

Hao Jiaqi was silent, glanced at Zhao Yurou from above her glasses, sighed, and said, "Alas, who made me ugly!" You are beautiful, someone hurts, and your family is also stained. My family, and they have to worry about me, and they have to live a hard life under the rule of devils, it's-"

Zhao Yurou didn't expect that her casual remark would cause her friends to be so sad, and even a little complaining, and she didn't know what to say for a while.

"You beg Yang Tianfeng!" Hao Jiaqi sniffled and pleaded: "He is very good to you, and he will definitely agree." ”

Zhao Yurou smiled bitterly, she really couldn't refuse her friend's plea, sighed, and said, "Okay, I will definitely help you with this." Alas, you don't know, I feel like I'm getting a little scared of him now. When I met with him the other day, I advised him not to mistreat the captured Japanese nationals, who were not combatants. But he glared at me and reprimanded me, and said I didn't understand anything. You know, I don't like to hear about this the most. ”

Hao Jiaqi blinked her eyes and thought about it, laughed, and said, "You two, it's really like what the play says, a pair of happy enemies." You see, he cares about your safety, and has transferred you here, which can be regarded as the rear, and is also equipped with guards for personal protection; As for you, you don't show weakness in your mouth, but you also know that he is sometimes fierce, but he can't do anything to you, and he still loves you everywhere. A few days ago, there was a big transfer of troops in the county, and it was said that Yang Tianfeng had stabbed a big basket in Sucheng and was being chased and besieged by devils, don't you also worry about his safety, can't you even sleep well? ”

Zhao Yurou frowned slightly and pondered for a while, then shook her head and said, "It's not like you said, what kind of happy enemies are the enemies of the previous life." Worried about him, as long as it is Chinese, who is hunted down by devils, I am also in the same mood. ”

"Feud in the past, love in this world." Hao Jiaqi saw that Zhao Yurou didn't admit it, and tried to find excuses, so she couldn't help laughing and said, "See how long you can deceive yourself?" Okay, okay, I can't talk about it! I still need your help with my family's affairs, please, thank you, my good sister. ”

Zhao Yurou rolled her eyes helplessly, and also had questions in her heart, is it really like what Hao Jiaqi said?

………………

The sun is about to set, the sky is condensed with a brilliant sunset, and the silky clouds are slowly fluttering.

The group stopped, and the front was already the junction of Xiao and Tong, and according to the prior contact, the corresponding personnel had already appeared, and there were hundreds of them.

"These brothers, we'll send them here." Xu Zhiqiang, who had already served as the chief of staff of the Guo detachment, bowed his hand.

"Thank you for sending me, please thank Chief Yang." It was He Dameng who returned the salute, who had helped Yang Tianfeng when he led his team to attack the devil army from a long distance, and promised to take care of the wounded of the advance team who stayed behind.

After going through many difficulties, He Dameng lived up to his promise, not only protecting the wounded, but also seeking medical advice, so that most of the wounded recovered. After that, He Dameng got in touch with Yang Tianfeng, personally led people, crossed the enemy-occupied area, and sent the recovered wounded back to Yongcheng.

Yang Tianfeng was naturally very grateful, but the way he could be grateful was unexpected by He Dameng and others. Seven or eight people were selected, and Yang Tianfeng gave them aliases and assigned them to the technical training camp to receive training together.

He Dameng and others did not know that there were some other anti-Japanese armed trainees in the technical training camp, all of whom used pseudonyms. After completing his studies, he will carry weapons and ammunition to various departments and go to the battlefield of resistance against Japan.

Long-term vision and overall vision are one of Yang Tianfeng's advantages. He always believed that all the troops that really resisted Japan, especially those around the Third Column, regardless of the size of their strength, would be beneficial to the operations of the Three Columns. Especially after the eastward expansion, he had a deeper understanding.

Seeing the power of the steel fist and the grenade launcher, He Dameng and the others were shocked, but also roughly guessed some of Yang Tianfeng's thinking.

Although the ants are small, they can eat elephants. Wouldn't the effect be even more significant if it could make a lot of ants stronger?

Although it is a bit of an exaggeration to describe the various anti-Japanese forces as mosquitoes, in fact there is not much difference, and they are indeed powerless to resist the Japanese army, let alone conquer a strong stronghold. In particular, after the Japanese army deployed the Type 95 railway armored vehicles, the casualties were not small, and the difficulties were even greater.

The Type 95 railway armored vehicle is a weapon specially equipped by the Japanese army to protect the safety of railway transportation in the occupied areas. It can quickly change from a railway operation state to a highway operation state, and can drive off the railway at any time to pursue the attackers. In terms of protecting the railway line, the threat of fighting Japanese soldiers and civilians is extremely high. (To be continued.) )
