Since 1935, Japan's infiltration into North China has been pressing down on layers of pressure, directly posing a threat to the Pingjin area. At the same time, the Japanese Navy has also strengthened its troops to Shanghai. Not only did the Japanese fleet berth at the estuary of the Yangtze River and along the Huangpu River for many years, but the Japanese Marine Corps also deployed heavy troops in Hongkou and Zhabei areas in Shanghai. In response to this situation, the National Government has stepped up the construction of the Wufu and Chengxi national defense lines, and held a large-scale offensive and defensive exercise in the mountainous areas between Lishui and Jurong in southeastern Nanjing in January 1936. (The historical large exercise was held in the autumn of 1935. Due to the plot needs, Lao Wan refused the exercise until 1936, and he also joined the exercise unit to the exercise unit that did not participate in the exercise at that time.)

The three German model divisions, the 36th Division, the 87th Division, the 88th Division, and the Central Military Academy Teaching Corps, which had been trained by German consultants for five years. The exercise was divided into two armies, the 87th Division of Wang Jingjiu and the Central Military Academy Teaching Corps led by Gui Yongqing were the Red Army, which simulated the Japanese army's attack on Nanjing after breaking through the national defense line. Song Xilian's 36th Division and Sun Yuanliang's 88th Division were the Blue Army, the 36th Division arranged the Jurong front line, and the 88th Division arranged the Lishui.

All the troops participating in this exercise were equipped with German equipment, and they were the most elite troops in China, the direct line among the direct line. The new German general counsel Farkenhouse and the Central Military Academy Education Director and the Commander-in-Chief of Beijing and Shanghai Security. At the suggestion of Farkenhouse, this exercise started from a practical perspective and carried out live air missile confrontation.

According to the exercise regulations, each participating unit entered its respective designated areas one day in advance. In addition to the 87th Division and the 36th Division, the 88th Division faced the Central Military Academy Teaching Corps. Although the three regiments of the Central Military Academy Teaching Corps had a 14,000-strong 88th Division, which had 14,000 troop 4.00. However, the Central Military Academy Teaching Corps was stationed in Nanjing and was the most well-equipped unit and was directly under the command of German consultants. Moreover, the corps directly under the sergeant battalion, artillery battalion, cavalry battalion, automatic convoy and other direct troops, which were much stronger than the 88th Division in terms of firepower and individual quality. In a sense, the 88th Division had to bear much pressure than the 36th Division who was also defending the 36th Division.

As the main force of the 88th Division, Shen Xiuwen's 264th Brigade where he was located was responsible for the defense of Lishui. The 527th Regiment deployed Huangshan, Luoshan and Chihushan positions in the eastern part of Lishui, and the 528th Regiment defended Lishui County. Shen Xiuwen's first battalion was arranged by Zhu Chi in Tuanshan, the only commanding heights in the northeast of Lishui County.

"Tuanshan is the barrier of the county town. If Tuanshan is lost, the county town will have no danger. Restoration, this time it is a mule or a horse, but I have to pull it out and slip away." After the defense meeting, Zhu Chi patted Shen Xiuwen's shoulder and instructed.

"Please rest assured that the regiment commander is in the position. He teaches the corps that no matter how crazy it is, our 88th Division is not a vegetarian." Shen Xiuwen said loudly.

"Okay, let them teach the corps to open their eyes this time. Humph, I want to see how the corps can break through the defense line of our 88th Division in two days. My 528th Regiment will block them in Lishui for two days." Zhu Chi also said with dissatisfaction.

The three model divisions of the Great Master and the officers of the Central Military Academy's teaching corps were all from Huangpu. Many of them were classmates. Shortly after the 88th Division was transferred from Sichuan to Nanjing, Huangpu classmates had to get together. Gui Yongqing, the commander of the teaching corps, Zhou Zhenqiang, the deputy commander and commander of the 1st regiment, and Zhang Kunsheng, the deputy commander and commander of the 3rd regiment, were both classmates of Huangpu First Phase. When the exercise plan was announced, Gui Yongqing and Zhou Zhenqiang told Sun Yuanliang shamelessly at a party that they taught the corps that could break through the defense line of the 88th Division within two days. Sun Yuanliang was so angry that he told this matter at a meeting of officers above the division camp. Now the 88th Division is united and must be held for two days no matter what.

When Chen Xiuwen returned to the Tuanshan position, his three companies had already begun to dig trenches and lay out defense lines. After Chen Xiuwen walked around, he frowned and said to the three company commanders who were following him: "This kind of defensive position cannot be done, it must be re-arranged."

"Why can't it work, battalion commander?" Cheng Dean, who had been promoted to the third company commander, asked with wide eyes. The first company commander Zhang Zhengjie and the second company commander also looked at Chen Xiuwen with confusion.

Chen Xiuwen pointed to the forefront trenches of Cheng Dean's third company that had been dug: "First of all, this trench is too shallow to effectively protect the artillery. Second, you see that your three companies are digging their own defense lines. Although there are some levels, this first-line trench setting is unreasonable. Once it is broken, it will collapse on the whole line. And I don't plan to put your three companies on the defensive position at the same time. At most one company is placed on the front defense."

"Battery Commander, although our terrain is strong, will there be too little frontal defense to put a company?" Zhang Zhengjie couldn't help but ask in confusion.

"As long as we have proper tactics, reasonable firepower, and strong fortifications, a company can withstand the attack of two battalions," Chen Xiuwen waved his hand and said.

The predecessor of the troops served in later generations of Chen Xiuwen was the famous Four Fields and Ten Columns, a unit that was good at fighting and blocking defense. It was guarding Heishan at that time, with less defense and more defense. It was not allowed Liao Yaoxiang's westward advance corps to move forward for three days and three nights. The fine traditions of the old troops have been preserved. In defensive and blocking wars, defensive fortifications and subordinates are quite particular.

Chen Xiuwen glanced at the three of them and pointed to the entire defensive position and said, "You three companies cannot fight on their own. They can connect the frontier trenches, and they cannot be single-line. They must be double-line, and they must be deepened and widened. They should be used as a trench that traps the enemy. Behind the trench is our first-line defensive position. Remember, to complete the curved trench, anti-aircraft artillery holes must be arranged in the trench. In addition, foxglove pits must be arranged on the rear side of the trench, machine gun fire must be arranged on the rear wings at both ends of the position to form cross fire. The second-line position is located on the top of the mountain to build an circular fortification. In addition, several mortar positions are arranged on the back slope."

Chen Xiuwen's words made Zhang Zhengjie and others stunned, and Cheng Dean even shouted loudly: "Oh my God, what a big project this is? We only have one day to arrange it. Is it too late?"

"No matter how big the project is, I will be able to construct it overnight before I have time, otherwise a fire from the other party would destroy half of our troops." Chen Xiuwen said with a frown.

Zhang Zhengjie and the second company commander did not dare to say anything, but Cheng Dean murmured in a low voice: "Is it necessary to be so serious? This is just an exercise, and all the air bags are put on."

"Fart." Chen Xiuwenhu looked at Cheng Dean and said sternly: "Exercise is also a battle. I want to stand the teaching team on this mountain for at least two days. If you don't want to do it, get out of here."

When Cheng Dean saw Chen Xiu Wenwan, he immediately lowered his head and did not dare to say anything again.

Chen Xiuwen looked at Zhang Zhengjie and the second company commander. Although they did not speak, the expression on their faces told Chen Xiuwen that it seemed to be a little bit of a big deal. After all, this is not a practical battle. Even in actual battle, they have never seen such a defensive position being arranged.

Maybe they still think that the war is far away from them, after all, they are now all troops guarding the capital. But Chen Xiuwen knew very well that the Japanese would come in next year, and the four troops currently being exercised will join the Battle of Songhu as the frontline to join the Battle of Shanghai, and then the Battle of Nanjing. Their four most elite troops were almost wiped out in these two battles.

Chen Xiuwen snorted coldly and said, "Hmph, you may think that the exercise is not a real war, it's just a formality. But I want to tell you that the exercise is a battle. Do you know why this exercise takes the Japanese attack on Nanjing as an imaginary enemy? Don't think that the Japanese are still far from us. I tell you that the war is not far from us. Maybe one day the Japanese will break through the national defense line to attack Nanjing. At that time, it will not be an exercise, it will be a real sword and gun to fight the Japanese. The Japanese are much more difficult to deal with than the teaching corps. Sweating now means less bleeding during the war."

Zhang Zhengjie participated in the 128th Shanghai War and was very clear about the firepower of the Japanese army. At that time, the 50,000 19th Route Army could not destroy only 3,000 Marines. If they were not facing the Japanese army pretending to be imaginary enemies, but the real Japanese army, their current defensive positions, like the real Chen Xiuwen, could almost destroy them all. His expression suddenly became solemn, and he quickly stood at attention and saluted: "Battery Commander, I will notify my brothers immediately to rebuild the fortifications according to your wishes."

The second company commander and Cheng Dean quickly accepted the orders and reworked the defensive positions again. For a time, the position of the Tuanshan First Battalion became a large construction site.
