Warlords: Rising from the Northwest Border and Sweeping Across the Powers

Yamashita Tomotake put a lot of thought into the defense of Yuancheng City. Not only did he place extremely dense firepower points on the city walls, but there were also six scattered artillery positions in the city. In order to prevent the enemy's long-range artillery attacks from directly eliminating the firepower points on the high points of the city walls, Yamashita Tomotake arranged a large number of reserve soldiers. Once the heavy firepower on the city walls was eliminated, they would immediately rush up at all costs. At the same time, the artillery units in the city would immediately launch a counterattack.

On the main traffic arteries in the city, Yamashita Fengwu used the residential houses to build multiple fire blockade lines. In case the city gates were breached, the continuous fire blockade lines would cause certain obstacles to the enemy and stop them from advancing.

At this time, Yamashita Tomotake had no way of retreat. Such a big change had occurred on the front line. Even if he led his troops to withdraw, he would definitely be sent to a military court when he returned to the Kwantung Army headquarters. Fujiwara Sanshao and others had already turned into charcoal on the battlefield. Someone had to take the blame for this defeat, and the most suitable candidate was him, Yamashita Tomotake.

After some discussion, Su Zhengyang decided to first let the Viking Division's rocket artillery battalion use their Smokebreaker six-tube rocket launchers to cover the firepower points on the enemy's city walls, and then adjust the strategy and launch an attack based on the battlefield situation.

The German Nebelwerfer rocket launcher, also known as the Screaming Mimi, is inferior to the Soviet Katyusha in terms of range and mobility. In addition, the German army did not attach much importance to rocket artillery units. In fact, the Nebelwerfer was originally used in chemical troops. It can fire 150MM poison gas bombs and smoke bombs. On the one hand, it can attack the enemy with biological and chemical weapons, and on the other hand, it can create a large-scale smoke screen on the battlefield to block the vision and interfere with the vision of the enemy armored forces.

Because of the existence of the Treaty of Versailles, from beginning to end, this batch of Nebelwerfer rocket launchers never actually fired poison gas bombs on the battlefield except during testing.

The long range of 5.3 kilometers and the 150MM caliber high-explosive rockets are enough to illustrate the enormous power of the Nebelwerfer.

Under Zhu Tanyin's command, 4 Nebelwerfer rocket launchers fired a salvo on a gentle slope kilometers away from Yuancheng. Although Nebelwerfer could only fire six rockets at a time and could not catch up with the Soviet Katyusha in terms of visual impact, its power was unquestionable.

Three or four hundred 150MM high-explosive rockets covered the entire city wall and the surrounding areas, instantly blowing a gap in the wall and removing a large amount of heavy firepower on the wall. Under this situation, the Northwest Revolutionary Army, which usually took advantage of the enemy being suppressed by artillery fire to launch an infantry charge, did something unusual under the command of Su Zhengyang and did not attack rashly. Instead, it continued to let observers observe the situation on the city wall and the city area from the commanding heights.

Sure enough, although a Fuso battalion responsible for guarding the south wall was almost wiped out under the fire coverage of the Smoker rocket launcher, in less than a moment, the Fuso side set up a second line of defense in the street area behind the city wall and built a heavy firepower cross network.

If the Northern Expedition Corps launched an attack rashly, they would inevitably be hit head-on by the Tokyo Division on their way to the charge and the moment they rushed into the gap in the city wall.

After listening to the observer's detailed report of the specific information he had observed, a smile appeared on Su Zhengyang's lips.

In the system mall, there is a special rocket shell called No. 150, which also has a caliber of 2MM and can be used by smoke throwers. But in fact, this special rocket No. has another secret. Its alias is phosgene bomb, its scientific name is carbonyl chloride, and its chemical formula is CO Cl.

Normally it is a colorless, volatile liquid with a faint odor, similar to moldy hay. This substance is 18 times more toxic than chlorine, and in low concentrations it affects the victim's sense of smell and taste, making it difficult to detect.

What is even more frightening is that phosgene is a very "insidious" agent. It will not cause obvious symptoms to the victim at the first time, but there will be a certain incubation period, and the time is inversely proportional to the inhaled concentration. If inhaled at a low concentration, phosgene will only cause the victim to shed tears and have a certain degree of suffocation.

However, if the inhaled concentration is high, it will cause chemical bronchitis accompanied by severe coughing and dyspnea, and chemical pulmonary edema will occur within 1-24 hours, leading to death. During this period, the victim will be tortured by secondary organ infections and have to endure the pain of continued damage to lung function.

In other words, the so-called Type 5 special rocket is actually another form of poison gas bomb, a real chemical weapon.

As long as it is launched into the target area, the gas bottles will shatter in the explosion, causing the poison gas inside to spread. The concentration is extremely high and can form a high-concentration poison fog that lasts for an hour on the spot. If it is dense enough, it can make a large number of enemy troops have difficulty breathing and suffocate to death.

It can be said that this is an extremely anti-human and cruel chemical weapon, but for Su Zhengyang, the crimes committed by Fuso in the Northeast are nothing compared to the mere poison gas bombs. Of course, in this time and space, there is also a Chauvin Convention similar to Versailles, which prohibits the use of chemical weapons in war, otherwise it will be condemned and sanctioned by the so-called International Peace League.

In Su Zhengyang's opinion, the so-called conventions and treaties are nothing more than weapons used by the strong to restrain the weak. As long as your own fist is strong enough, will it hurt you to let them condemn and protest?

The price of a Type 300 special rocket is 150 points, which is almost three times the price of an ordinary MM high-explosive rocket.

Su Zhengyang communicated with the system in his mind: "System, I am now purchasing 300 Type 5 special rockets. Can you arrange for their delivery immediately?"

[Reply to the host, since the quantity purchased by the host is not large, it can be delivered to the host's area within three hours. Are you sure to purchase it? ]

Su Zhengyang immediately chose to confirm, and then his thoughts returned to reality.

"Don't worry. Now the Tokyo Division in the city has reached a point of doom and gloom. They have no choice but to fight to the death with us. If we rashly launch a general attack, even if we take down the source city, it will cause a large number of casualties. I have a way to take down the source city without bloodshed. Wait a few hours until a new batch of supplies arrives, and the answer will be revealed."

Listening to Su Zhengyang's words, Liu Chengxu, Gu Chenghai, and Yang Chengjun looked at each other. In this situation, morale is high, shouldn't they charge in at once?

Even if there will be some bloodshed and sacrifice, there will always be casualties in war.

Su Zhengyang's purpose, in addition to avoiding losses, was to try out the power of this so-called phosgene bomb.
