When explaining the defense of Nanjing, Wang Haitao focused on the use of ground types and the construction of fortifications. At this time, Wang Haitao brought the civil engineering experience of the People's Liberation Army summed up in the war that later generations learned in the classroom. For Wang Haitao, this is a confused account, and he doesn't know what kind of results will be brought by using the things of later generations to influence the present.

However, Wang Haitao's remarks opened the eyes of the officers of the Eighth Route Army who were listening to the lecture, and it turned out that the defensive positions could still be built to this extent, and if they had learned these things earlier, there would not have been so many officers and soldiers sacrificed in the previous battles. After Wang Haitao finished speaking about the defense of Nanjing, ten days had passed. Many of these officers came to Yan'an directly from the front-line troops, and although they only stayed for about ten days, some people could not sit still, and there was still a lot of military affairs in the front-line troops.

The CCP side could only end this training, and at the same time ordered another group of officers to come to Yan'an to participate in the training. Wang Haitao has been in Yan'an for more than half a month, and he has not had time to get a straight and in-depth understanding of the strength of the Chinese Communists, and it just so happened that the new officers who attended the lecture had not yet arrived, so Wang Haitao also proposed to the Chinese Communists to take this opportunity to go to the defense area of the Eighth Route Army to have a look.

The Chinese Communists readily agreed to Wang Haitao's request and arranged for General Zuo Quan, deputy chief of general staff of the Eighth Route Army, to accompany Wang Haitao on a tour of the defense area. General Zuo Quan returned to Yan'an this time to report to the Central Committee on the situation in the Taihang Mountain base area, just in time for Wang Haitao's arrival, so he stayed. Wang Haitao wanted to drive out, but considering that the places he wanted to go to were mostly mountains or ravines, and it was inconvenient for cars to pass, he rode away with General Zuo Quan.

The first stop Wang Haitao went to was the Huangyadong Arsenal, the Huangyadong Arsenal is not large, and the equipment is far from advanced, but its significance is by no means ordinary. This is the largest arsenal owned by the CCP, and the ammunition it produces is the largest source of ammunition on the CCP's side, in addition to the seizure department, so the CCP also attaches great importance to it.

Wang Haitao was accompanied by only two guards, but General Zuo Quan was surrounded by one of his own guard platoons. Wang Haitao deeply regretted the untimely death of General Zuo Quan, and during the conversations along the way, General Zuo Quan's optimistic spirit and firm belief in the victory of the war against Japan aroused Wang Haitao's respect and favorability. Wang Haitao planned to equip General Zuo Quan with a platoon of new weapons before he left Yan'an and returned to the Taihang Mountain base area, which might allow General Zuo Quan to escape.

After walking for two days, when approaching the Huangyadong Arsenal, Wang Haitao and his party encountered a very strict examination by the Huangyadong guard troops, and General Zuo Quan was also prepared for a long time and showed a letter of introduction issued by the headquarters of the Eighth Route Army. Even so, Wang Haitao and the others were only allowed to enter the interior after they were all disarmed. The director of the Huangyadong Arsenal personally received Wang Haitao and General Zuo Quan and took them to visit the entire Huangyadong Arsenal.

To be honest, there are not a few intact machines and equipment in the entire Huangyadong Arsenal, and the only old-fashioned lathe is regarded as a treasure and will not be used easily. The arsenal could not produce guns at all, it could only be reloaded, and the most produced were the ones that were not very powerful*. And when repairing firearms, only some minor problems can be repaired, and major problems cannot be repaired.

After visiting the Huangyadong Arsenal, Wang Haitao was very disappointed, just knowing that this Huangyadong Arsenal was very ugly, but he didn't expect it to be so ugly. Not to mention the inability to produce guns and ammunition, even the self-made * is very powerful because of material problems, so the reloaded bullets have a short range and unstable trajectory, which can only ensure accuracy within tens of meters.

However, during the visit, Wang Haitao also saw that both cadres and workers in the arsenal were carrying forward the spirit of diligence and thrift, and they would never let go of anything that might be used, and at the same time, everyone rushed to do the hard work. Perhaps it is with this spirit that the CCP can develop and grow step by step, thus winning the final victory!

From the Huangyadong Arsenal, Wang Haitao did not see the equipment and technology that surprised him, but saw a hard and simple style, a serious and rigorous work attitude, a down-to-earth work spirit, a positive spiritual outlook, and saw that everyone's heart was full of hope and belief in victory, which may be the reason why the CCP can have the last laugh!

After leaving the Huangyadong Arsenal, Wang Haitao and his entourage went to the newly built penicillin pharmaceutical factory of the Chinese Communist Party, which was guarded more tightly than the Huangyadong Arsenal. After Wang Weikuan led Wang Haitao and General Zuo Quan into his office and talked to Wang Haitao, Wang Haitao realized that this pharmaceutical factory was already under the direct control of the Central Committee of the Communist Party of China, and the headquarters of the Eighth Route Army had no right to give orders to it.

It turned out that after this pharmaceutical factory was built and the first batch of finished penicillin was produced, it was directly controlled by the Central Committee of the Communist Party of China because of the huge effect of penicillin, a special drug on the wounded. In addition to supplying the front hospitals, a small amount of penicillin is now produced to exchange necessities with the Soviet side. In the eyes of the Central Committee of the Communist Party of China, this pharmaceutical factory is already a more important existence than the Huangyadong Arsenal.

The CCP's behavior Wang Haitao is understandable, as a CCP that is controlled everywhere and isolated, using penicillin, an advanced drug, to exchange some necessities with the only ally, the Soviet Union's big brother, Wang Haitao really can't say anything, but Wang Haitao still wants to return to Yan'an to remind the CCP that products can be exchanged, and technology must not be exchanged. This big brother of the Soviet Union is actually not very kind.

Wang Haitao and General Zuo Quan walked outside non-stop for six days, and the CCP sent people to report that the second group of officers who were listening to the lecture had arrived in Yan'an. Although Wang Haitao still wanted to take a look around, he couldn't let these people who came to listen to the lecture wait for a long time, so he could only rush back to Yan'an with General Zuo Quan. As soon as he returned to Yan'an, General Zuo Quan said goodbye to Wang Haitao and wanted to rush back to the Taihang Mountain base. Wang Haitao was so good at saying that he let General Zuo Quan stay for another three days.

In the past three days, Wang Haitao threw General Zuo Quan's guard platoon to Tangshan Leopard, asked Tangshan Leopard to conduct emergency training for them, and at the same time asked Tangshan Leopard to draw out a platoon's equipment and distribute it to them. Wang Haitao didn't know if this would change history and save General Zuo Quan's life, but he still wanted to give it a go. Three days later, when the rejuvenated platoon of soldiers lined up behind General Zuo Quan, Wang Haitao knew that there was only so much he could do.

After sending off General Zuo Quan, Wang Haitao began to attend classes every day, and ten days later, this group of officers who came to complete their training again, counting the days, Wang Haitao also stayed in Yan'an for nearly forty days, and it was time to leave. In the past two days, Wang Haitao inspected the scene of the training of the Central Guard Corps, and the things that should be taught to the Central Guard Corps have been taught to Tangshan Leopard without reservation, and it is up to them how much they can learn and how much they can play on the battlefield in the future.

After the inspection, Wang Haitao decided to conduct a debriefing exercise with the Chinese communists two days later, and this debriefing exercise also received great attention from the Chinese communists; how much has the Central Guard Corps learned in the past month, and how much has changed will be reflected in this debriefing exercise. Wang Haitao also came up with a plan for the report exercise, which was agreed by the Chinese communists.

In this debriefing exercise, Wang Haitao's two companies were still the Blue Army, and one battalion of the Central Guard Regiment and one reconnaissance company were the Red Army, but the difference was that this time the blue side was used as the defender to guard the hilltop position, and the red side was used as the attacker to attack the hilltop position. The live-fire report of the separate artillery brigade was also added before the exercise.

In the blink of an eye, on the day of the debriefing exercise, the same place, the same crowd of people. After the leaders of the Central Committee of the Communist Party of China and the commanders of the Eighth Route Army were seated on the viewing platform, it was supposed to be the troops of the Central Guard Regiment and Wang Haitao entering the field, but before these two troops entered the field, there was a roar of engines in the distant scene accompanied by the loess sky.

Listening to the voice, Wang Haitao knew that it was a truck dragging the artillery over, and sure enough, in the dust, heavy trucks dragging 75-caliber field guns appeared. A total of 50 trucks dragged 50 field guns in front and behind, causing the people who had never seen so many artillery pieces and the officers and men of the Eighth Route Army to let out huge cheers.

At this time, even these leaders on the spectator stood up excitedly, after all, the CCP's troops had never had so many advanced artillery pieces at once. The convoy passed through the viewing platform in turn, and it really had a bit of a taste of a military parade in later generations. Coming to the open space about a kilometer from the observation platform, the truck stopped, and the officers and men of the Independent Artillery Brigade jumped from the truck, and they untied ten guns from the truck and began to skillfully set up the gun emplacement.

Five minutes later, all ten artillery pieces were in place, and the ten mounds of earth that were used as targets had already been set up three kilometers away. At this time, the artillerymen began to aim, adjust the muzzles, load live ammunition, and everything went in an orderly manner. After the preparations were completed, the commander consulted Wu Ting, the commander of the artillery brigade, and after receiving the order to open the artillery, he ran back to his original position, and the red flag held high fell downward, shouting: "Open the artillery!"

In a deafening burst of artillery, the ten field guns fired shells one after another, and the artillerymen quickly withdrew the shells, and then reloaded, and the new shells were just loaded, and the explosion of shells was heard in the distance. According to the flag, three out of ten shells hit the target, and the other seven were close misses. After three rounds of artillery fire, all ten mounds were hit, which made Wang Haitao breathe a sigh of relief.

Of course, this result is only qualified in the eyes of Wang Haitao, but in the eyes of these leaders of the Communist Party of China, it is a very good result, so these leaders of the Communist Party of China have smiles on their faces. Commander-in-Chief Zhu and Deputy Commander-in-Chief Peng also came to Wang Haitao in person to express their gratitude to Wang Haitao again. It is no wonder that these leaders of the CCP are full of smiles, because now the CCP's troops finally have an artillery unit that can really take action.

Amid the cheers of the officers and soldiers of the Eighth Route and the people, the Independent Artillery Brigade drove a truck and dragged the artillery out of the exercise ground, and at this time, the Red Army of the Central Guard Regiment and the Blue Army under Wang Haitao drove into the exercise ground in full armed. With the experience of the last exercise, the Central Guard Regiment of the Red Army has relaxed a lot in this exercise, and the chief referee of this exercise is still General Peng Dehuai.
