Under the guidance of several civil engineering construction masters, the 600 training soldiers spent nearly two months building a small street, various houses, and even two three-story buildings.

Of course, the houses are rough, with bare masonry and reinforced concrete.

But what is the difference between the exquisite decoration and the rough masonry in the final outcome of the artillery fire? For both warring sides, it was a grave of death. What the teaching team has to do now is to try to climb out of this grave of death, and even if they want to die, they must have the ability to pull a few more Japanese soldiers as backs.

In the process, they learned not only how to build houses, but also the structure of various houses, and learned to build fortifications based on houses.

Moreover, under the reminder of Zhang Ruhao, several master builders are also fully devoted, not only to teach everyone to build houses, but also to teach soldiers how to build fortifications stronger, from street fortifications to field fortifications, several civil engineering experts simply showed all their skills, and even a few people because of disagreement, in the training ground to fight red.

Several white-faced scholars have been in the barracks for two months, and they are also contaminated with a trace of military rudeness, if it is not for someone to pull them, it is probably not impossible to stage a full martial arts.

However, there was also a great interest in this, and the instructors who began to study the construction of fortifications together with the soldiers were much more direct than the civil engineering experts. In order to teach the team, Langtuanzuo took out almost all of his family background, a total of six twin-mounted 20mm machine guns were transferred to three, and 82 mortars were quite a lot, but Langtuanzuo was afraid that the power was not strong enough, and even transferred one of the two baby Bofors mountain guns from Zhao Ergou Artillery Battalion for training.

For this reason, Zhao Ergou tearfully confessed that Li Guobin, the deputy captain, must treat his baby well, and when he left, he was reluctant to leave, so he almost didn't kiss him on the barrel of the Bofors Mountain Cannon.

The instructors directly set up twin machine guns and Bofors mountain guns to bombard the fortifications, and if they collapsed, it was wrong, and if they didn't collapse, they were good, and on the real battlefield, the Japanese army still had 150 heavy guns or even larger calibers, and no one dared to joke with their own lives.

It can be said that the two months from early October to late December benefited the soldiers and instructors who worked as construction workers. In the past two months, what they have learned is the technique of saving lives, and as the backbone, after returning to the companies, they will bring back these things they have learned in the teaching team, which is also a part of Captain Liu's assessment of them.

Liu Lang felt that this method was very good, so he had already stuffed a total of five special forces into the teaching team, including Shi Datou, Cai Dadao, Niu Er, and Zeng Shui and Erkou who had just been called back from Rehe in the north.

Street fighting is also a necessary skill for special forces, and special forces who are already proficient in field warfare must master this. At the end of the year, when the special forces who have gradually begun to withdraw from the northeast and the two special forces located in the Sumanda Sea return, this will also become their training ground.

When the 10 red instructors dressed as lieutenants and captains of the newly formed 61st Brigade appeared at the training base of the teaching team, it was already mid-January. More than three months have passed since Liu Lang put forward the demand for instructors to the Red Central Committee.

It's not that these red officers don't want to come, but they really can't.

It turned out that when the red troops arrived in Wuqi Town and the local red troops joined forces to announce the end of the strategic transfer, the bald bosses once again used the method of the red Soviet base areas, using the warlords of the four provinces of Gansu, Ning, Jin, and Shaanxi around northern Shaanxi to carry out a thorough blockade of northern Shaanxi, not to mention that all caravans were not allowed to enter the area, even ordinary people were extremely difficult to enter, and anyone who entered the area was regarded as defecting to the enemy. For this reason, I don't know how many ordinary people who visited relatives and friends were killed by them.

In such an environment, even if it is as strong as the Chinese business group, it is helpless, and at most it can only reach the border of Shanxi and Shaanxi, which borders northern Shaanxi, and is politely driven back by the local garrison.

Liu Lang naturally couldn't go to Comrade Lao Yan to dredge up, with that person's shrewdness, I was afraid that as soon as the words came out, Liu Lang's mind would be guessed by him. Even if you don't say it now, once you have something to deal with Liu Lang in the future, a big hat of collaborating with the enemy will immediately be buckled on Liu Lang's head, with the temperament of that old man in Shanxi, it is almost impossible but inevitable.

The old man of Shanxi, who has ruled Shanxi for more than 20 years, is the most shrewd businessman, and can judge at any time which side of investment is the most advantageous. In the past time and space, this bald boss was a false and wrongful snake, and secretly he was also eyebrow-raising with the red troops, and even the Japanese hooked up. However, that side did not get what they wanted in Shanxi Laohan, who always firmly controlled Shanxi, his territory, and the Japanese who were dragged out of patience by him with delaying tactics were all scolding their mothers behind their backs, but they were helpless. The old man in Shanxi has any discipline in this regard, and he may not scatter eagles when he sees rabbits.

Since the main force of the red army arrived in northern Shaanxi, although he did not send troops to cross the Yellow River to cooperate with the bald boss's encirclement plan, but it took a lot of effort to spend several months along the Yellow River from the north of the junction of Shanxi Northwest and Northern Shaanxi from Hequ and Baode, south to Yonghe and Daning, and built more than 1,000 high towers and dark forts, each of which garrisoned one or two shifts, and more than one row of troops stationed at important ferries. The total strength of the front line of river defense amounted to as many as four independent brigades.

Therefore, as early as the end of October, the 10 cadres who had completed their underground work and were preparing to go to Sichuan were unable to leave northern Shaanxi for a while. Shanxi was surrounded by the old men of Shanxi with heavy troops like iron buckets, and the Ma Jiajun in Gansu and Ning were wiped out by the Red Army in a battle with a cavalry division, and the Red Army was like a great enemy. The only way to go was to face the Northwest Army and the Northeast Army of Shaanxi, which were about to leave the Red Army.

Liu Lang knew that Zhang Shaoshuai and General Yang, who were sitting in Xi'an, did not want to fight to the death with their soldiers and the red troops, and they were even very interested in the principles and policies put forward by the red troops to establish a united front to resist Japan, although they had not yet sent people to contact each other as they had done in 1936, but they were definitely not so hostile.

Therefore, Fan Xudong, the general manager of the Chinese commercial company, secretly went north to Xi'an, conducted commercial negotiations with Zhang Shaoshuai, and after paying 1,000 tons of fertilizer powder to Shaanxi free of charge and promising to repair the 100-kilometer section of the Sichuan-Shaanxi Highway in Shaanxi at cost price, he finally obtained permission to send a caravan into northern Shaanxi to transport Yanchang oil, and half of the refined gasoline and diesel was also handed over to the Northeast Army and the Northwest Army as taxes.

Neither of the parties is afraid that the other party will poke out this secret transaction, and if either party tells this secret, it will be the rhythm of the collective end of both parties. Of course, with the shrewdness of the heads of both sides, I am afraid that they have already thought of the scapegoat for the golden cicada shelling, and once the matter is leaked, someone will always come out to top the bag. On the one hand, the defenders will accept bribes and connive with enemy businessmen to traffic in enemy funds, and on the other hand, the private behavior of the company's subordinates, and the headquarters of the group will not know about it at all.

However, the meeting between the general manager of Huashang Group and Zhang Shaoshuai was a matter of road construction and sales cooperation with fertilizer powder and steel, as evidenced by a contract. The excuse that the fault is done by temporary workers is not a patent for the future, and the bigwigs have been playing this for a long time.

Moreover, the two sides now have enough power to make the government throw a rat trap, even if the temporary workers can't stand the tank, the upper echelons must pinch their noses and catch the temporary workers, which is the real reason why both sides dare to brave the world's condemnation to reach a secret cooperation.

Liu Lang knew that these two would definitely agree, because these two bold and bold men were even arrested a year later by the bald boss who came to Xi'an to supervise the war, so would they be afraid of a little "smuggling"? Not to mention the temptation of up to tens of tons of gasoline and diesel per month.

After coming and going, it was already mid-December when the caravan took advantage of the night to enter the northern Shaanxi territory and pick up ten red cadres, and after a small half-month trek, when it arrived in Guangyuan, Sichuan, it was naturally January 1936.
