Over the next few days, the integrated independent regiment gradually got back on track.

The boot battalion began their training in full swing, and the officers and men of several infantry battalions and engineer battalions became students and entered the classroom.

However, what they learned this time was not any marching tactics, but civil engineering work.

After the battle of Luo Wenyu, Liu Lang deeply felt the importance of fortifications, if there were no strong enough fortifications, no matter how strong the light firepower of the independent regiment was, he was afraid that it would not be drowned under the heavy artillery of the Eighth Division. However, not every time you meet the Japanese army, the Japanese will give the independent regiment a month to let you build fortifications, and not every time the independent regiment will have the opportunity to garrison in the mountains.

In the all-out war that is about to break out in the future, the independent regiment is to fight with the Japanese army in the field, whether it is a plain or a city, everyone in the independent regiment must first learn to use the terrain to build fortifications, only better protect themselves, in order to destroy the enemy more effectively.

The Battle of Songhu is the best example in the future, the Chinese and Japanese invested millions of troops in this plain city, but the superior national army finally exhausted the elite in that flesh mill, in addition to the Japanese with large-caliber naval guns to help, the rudimentary fortifications of the national army are also one of the reasons for its heavy losses.

Of course, the low-lying area of Shanghai, where the terrain is full of water when you dig two feet is also one of the disadvantages.

Two civil engineering experts invited from Chengdu and Zhang Ruhao, deputy of the Huangpu High-level Student New Regiment, were the main lecturers of the two-month civil engineering operation theory and practice class of the infantry of the independent regiment.

The newly expanded artillery battalion does not need Liu Lang to worry about, although all the promised new artillery is not in place, but Zhao Ergou gave Liu Lang a training plan for nearly half a year on the afternoon of the personnel appointment, and a series of subjects such as long-distance artillery marching training, artillery live-fire training, artillery reconnaissance training, infantry and artillery cooperation training, front-line infantry guidance and tactical training and so on made Liu Lang completely impressed by Zhao Ergou.

Needless to say, Deputy Zhang, who has just entered the artillery battalion, may have contributed a lot to this complete training plan. Since Zhao Ergou is working so hard, what else does Liu Lang say? With a stroke of the pen, he agreed to all his requests, even the only one hundred and fifty shells in the stockpile.

There is no shortage of money in the independent regiment, what is lacking is well-trained gunners. The artillery battalion is not the one hundred and ten people in the past, the number of personnel is as high as 390 people, most of them are still recruits who have not even touched the gun body, and at least two hundred and fifty recruits are under the command of the artillery battalion at the request of Zhao Ergou. According to Zhao Ergou, artillery is not suitable for those stupid infantry who impulsively carry rifles when they see the enemy coming up, although he was almost not chased by Chi Dakui to run two laps on the training ground when he said this, but it still sounds like there is some truth, at least the recruits are easier to transform into some.

As soon as Xiao Fenghua's security office was established, he directly took over the defense of the independent regiment base, the three factories located in the mountains behind the base, and the scientific research base of Comrade Lao Ye in the base. It was only at this time that the chiefs of the ministries knew the reason why there was no specific provision for the establishment of the security department in the announced establishment, and that was because he needed time to determine the personnel.

All the personnel of the security department were selected by Xiao Fenghua by various departments, but he needed time to screen, and all the personnel selected by him were all people who performed well in the Battle of the Great Wall and were innocent.

From soldiers to non-commissioned officers to lieutenants, they are almost the backbone of each department.

Seeing that the backbone of his new arrival was transferred away by Xiao Fenghua's security office like this, would the chief officers of each department be willing? found Liu Lang to complain, but was strongly rejected by Liu Lang one by one. Zhao Ergou, who has never suffered a loss, pointed to the nose of his old brother Xiao Fenghua and scolded the consequence that the artillery battalion was arrested three times by the newly established military discipline picket team of the security department, and for two consecutive days, ten people in the artillery battalion were confined, and twenty people stood in a military posture in the playground for the recruits to watch. They were all "sunburned" into pork liver.

So, everyone died down. At this time, everyone in the independent regiment can be regarded as seeing that the security department is a military intelligence department that prevents infiltration and espionage externally, and internally, it is the supervision office that supervises the "hundred officials", and its authority is great!

Liu Lang was also very satisfied with the supervision organization of the independent regiment that he had set up single-handedly, similar to the "Military Discipline Inspection Commission" of the later republic, and only ten days after its establishment, not only was the arrogance of the post-war independent regiment about to come out of the air cleared, but also the screening of a large number of outsiders in the three factories also achieved great results, a total of five workers who were connected with the warlords of various factions in Sichuan, and even found out that two garment workers of Sichuan nationality were directly from the national government, and the largest intelligence agency in Asia, which was pervasive and penetrated, had already shown its might.

Liu Lang secretly rejoiced, if it weren't for the fact that the workers were strictly forbidden to enter the base, he didn't know how much the national government already knew about the Independent Regiment. Of course, this is not the most terrible, the most terrible thing is that China's biggest enemy, Japan, can't be the independent regiment on this side, the Japanese devils over there know how the independent regiment is going to beat them, and that battle is really impossible to fight.

The strength of the security department has been strengthened once again, and in addition to the 40 officers and men with clean net worth, who have the military status of the independent regiment, there are also 200 reserve militiamen who have been recommended by the veterans who have been assigned to live in various villages, and they will be sent to Sichuan and the surrounding areas after half a year of training, to become the eyes of the independent regiment, not to be admitted to the army, but the salary is several times that of ordinary officers and soldiers.

Especially in Guangyuan, where the independent regiment is stationed, all outsiders who enter Guangyuan will be closely monitored.

In addition to the Chinese Business Group, in the next four years, the Independent Regiment will gradually develop and improve its own intelligence network.

Xiao Yangniuer and Fan Ziran had already left the base for Chengdu on the day when the independent regiment was still calculating the reward, and the chemical fertilizer plant of the Huashang Group on the outskirts of Chengdu had been selected, and the two senior executives of the Huashang Group were needed to attend the groundbreaking ceremony.

The address of the iron and steel smelting and manufacturing plant is five miles away from the mountain behind the independent regiment, and the small iron ore mine developed by the independent regiment will provide raw materials for the iron and steel plant, and the land price has been negotiated with the Guangyuan county government, and the construction will start soon.

As the first commander of the Independent Regiment, Liu Lang was naturally not idle.

The scientific research team led by Comrade Lao Ye has already refined the first batch of clinical drugs of sulfonamides in Shanghai, and since returning to the Guangyuan base for half a month, a batch of sulfonamides has been purified again, and the 20 sick villagers selected around the base will become another tester of sulfonamides, and the villagers who have basically been sentenced to death by the village doctor have voluntarily become the second batch of sulfonamide clinical trial "medicine people" made in China after receiving the "condolence money" of 50 yuan per person. It was also their last chance to regain their lives.

I have been using sulfonamides for two days, and I haven't seen much effect on the first day, which is the day when it is announced that they are alive or dead, and whether the second clinical trial of sulfonamides will be successful. If successful, then sulfonamides will be mass-produced and stored, and when sulfonamides are marketed abroad, domestic sulfonamides will also be marketed at the same time.

Liu Lang and a group of high-achieving students from Huaqing University who participated in the development of sulfonamides waited anxiously outside the quarantine area, waiting for the final diagnosis of the 20 patients inside by the military doctors of the Independent Regiment.
