He is not the only instructor of the special combat team, and Li Yifeng is in charge of the training of military quality, and he will participate in the training even when Chen Xiu is free.

"Instructor."

Chen Xiu nodded, "Let's gather." ”

"Yes!"

Today, Chen Xiu is going to give them a lesson on first aid.

Soon, a hundred people gathered in front of Chen Xiu.

"Everyone knows that whether it is on the battlefield or behind enemy lines, working underground, even ordinary people, can be injured." Chen Xiu spoke, "If you are injured, many times, you will not have the conditions to seek medical treatment, not to mention the frontal battlefield, generally behind enemy lines, lack of materials, lack of medicines, and even, when you do underground work, you can't seek medical treatment openly, at this time, what should you do?" ”

This was the first time Chen Xiu had given them a medical course.

Everyone found that what Chen Xiu said was very reasonable, not all troops had medical conditions, and Chen Xiu had already told them about the nature of their work, and many times, they had to carry out special tasks.

"So, what I'm going to teach you today is some first aid knowledge, some emergency trauma treatment, and even the treatment of gunshot wounds."

……

"Mr. Sack, here, it should be like this." Zhang De's face was black, and he drilled out from under a machine.

"Oh yes." Sack nodded, his face excited, since Will left, he had become the chief engineer of the base, so, he was still very grateful to Will for being able to recommend him for this position. Then, one project after another, as well as several new students who have just graduated from school, undoubtedly gave him a great boost. "De, you come out first, I'll try to start it and take a look."

The mortar barrel manufacturing process relies on traditional mechanical cutting and grinding of materials to achieve the desired geometry.

And the manufacture of mortars, the most important thing, is the manufacture of body barrels.

"Okay." Zhang De answered, then stood up and watched Zak start the machine.

At the base in Liuba County, everything is developing in an orderly manner according to the plan, except for some progress that has been stranded because the problem has not been solved.

The time is also very fast to May.

……

"Come, let's draw out the recent offensive line of the Japanese army. At the beginning, they surrounded the west side of Xuzhou from the north and south. In the south, the 9th and 13th Divisions marched north along the west bank of the Beiqi River and the Vortex River from the Bengbu area, and on the 13th, after capturing Mengcheng and Yongcheng, they attacked Xiaoxian and Dangshan in Jiangsu; The 3rd Division entered the Dayingji area from Bengbu and attacked Suxian. In the north, the 16th Division crossed the canal from Jining, Shandong, and on the 14th, after capturing Yuncheng, Shanxian, Jinxiang, and Yutai, it advanced to Fengxian and Dangshan in Jiangsu; The 14th Division crossed the Yellow River from Puyang, Henan, and after trapping Heze and Cao County in Shandong, it went straight to Lanfeng, Henan; At the same time, after the 10th Division handed over the operations in the Hanzhuang and Taierzhuang areas to the 114th Division, it crossed Weishan Lake near Xiazhen and attacked Peixian. A lieutenant general of the national army held a small wooden stick and pointed to the map, "Do you see anything?" ”

"The purpose of the devil is to encircle and annihilate our main force!" A major general was shocked!

"Commander, do the devils really want to surround our main force?"

"Hmm." One of the generals nodded, "At the moment, it seems that the devil's intentions are like this. ”

"What about Xuzhou?"

"It depends on what the chairman means." The admiral spoke, sighing, "Order the troops to continue to hold on until a new military order is issued." ”

"Yes!"

In mid-May, when the increasingly tragic battle reports from the front continued to reach the case of Chairman Jiang of the Wuchang Kuomintang Military Committee, Xuzhou was suddenly faced with a serious crisis, which calmed down his brain, which was a little dizzy because of the victory in Taierzhuang. Chairman Chiang suddenly realized that the intention of the Japanese army was to encircle and annihilate the main force of the Chinese army in Xuzhou.

"Yunong, immediately call He Yingqin, Bai Chongxi, Chen Cheng, and Feng Yizhong to come over!"

"Yes!"

Afterwards, several people went to Chairman Chiang.

"Take a seat."

"Sit down. Recently, the situation on the front line is very bad, various places have fallen, and Xuzhou has a situation where it is about to be surrounded. All see, what are the thoughts. ”

……

"For today's plan, we can only let Li Zongren be under his command and avoid a decisive battle with the Japanese! Evacuate! in order to keep the main force from losing! ”

"Eh, it looks like that's all there is to it."

Chairman Jiang closed his eyes and sighed, "Then, send a telegram to General Li Zongren and order his troops to avoid the decisive battle, evacuate Xuzhou, and break through quickly." ”

"Yes!"

……

When an evacuation telegram was placed on the table, Li Zongren could only sigh, and only in the morning did he see that the devil was intending, and in the afternoon, he received the evacuation telegram. If the main force is beaten by the Japanese, it will be even more difficult to lose.

On the 16th, the Fifth Theater ordered all units to break through to the mountainous areas on the border of Henan and Anhui. The Chinese army fought and retreated, and the formation was not chaotic, and they retreated to the west and south in an orderly manner. The Japanese army blocked one place, the Chinese army rushed to one place, and everything was broken, and the army gathered in the south of Henan and the north of Hubei, and all roads rushed out of the encirclement one after another.

In order to avoid a war of attrition with the superior enemy, when the enemy forces from all walks of life were encircling Xuzhou step by step, Li Zongren ordered the defenders of all walks of life under his command to retreat to the mountainous areas and lakes and marshes after a little resistance, and carried out guerrilla warfare of "breaking the whole into pieces" and entangled with the enemy for more than a month.

"Tuanza, the devil has retreated." Iron Pillar spat out, and although they retreated safely, he was more or less injured.

Zhou Wen nodded, "The devil wants to encircle and annihilate our main force, but the devil can't imagine that our commander will send an empty city to them." ”

"Haha, too."

"Tell the brothers, rest for a while, we have to continue the march."

"Yes!"

……

"Sure enough, the yield of a rotten apple is actually dozens of times that purified by our laboratory!" Wang Yanran sighed, "If that's the case, how can we get our high-yielding strains!" ”

"Sister Yanran, don't worry, I heard that Zhang De seems to have received a suggestion from Brother Chen, and he is researching what ultraviolet lamp, saying that it is for us to mutagenesis, maybe it will be useful then!" Wu Qian smiled and reassured, who will tell her that she obviously studied chemistry, but now she is doing biological work.

"Eh, hopefully. Now we're ready for everything else. Wang Yanran looked at the entire workshop, a large number of glass cabinets, and even they had prepared a large batch of culture medium, including 1% glucose solution, 80% alcohol, 1% lactose, 1% calcium carbonate...... Wait, but right now, there's just one high-yielding strain left! Everything is ready, only the east wind is owed!

"If the high-yielding strains can be made, then, as soon as we start producing here, it will be the real daily profit!" Wu Qian smiled, "Even Brother Chen's arsenal doesn't make money like us." ”

"You, this medicine, it will definitely be put in Liuba County Hospital at that time, and it will make money, it's good if you don't lose money!" Wang Yanran was helpless, "However, we have to make foreigners' money!" ”

"Sister Yanran said yes!"
