After clearing the remaining Japanese troops from the position, the KPA launched an attack on the last three main buildings: the Kwantung Governor's Office War Department Building, the Sino-Russian Dosheng Bank Building, and the General School Assembly Hall, which happened to be three-storey, two-storey, and one-story respectively.

At this time, hundreds of Japanese soldiers who hid in these three buildings each set up rifles at the windows and gates of each building to put up their last resistance. The People's Army quickly dispatched troops, first surrounded the three buildings, then set up machine gun and mortar positions, suppressed the buildings with fierce fire, and also sent some soldiers with good marksmanship to snipe the Japanese soldiers at the window.

After a short time, the Japanese troops in these three buildings were suppressed by the fire of the People's Army, and the gates were opened, so the People's Army immediately organized troops to assault these three buildings.

Due to the narrower terrain inside the building, the assault could only use squad and platoon troops, with one platoon on each floor. Since the Kwantung Governor's War Department building had three floors, the actual number of troops invested was one company, but the three platoons were invested in turn. The 1st Company of the 2nd Battalion of the 1st Marine Regiment was responsible for the assault on the Kwantung Governor's Office War Department building, and the 1st Platoon was the first to attack.

Before launching the assault, platoon commander Liu Fuxi first ordered the squad leader and deputy squad leader of the platoon to put down their rifles and load the Type 96 pistol with the handle, and each other soldier would make up for it. In the training of urban warfare, the KPA has carried out some exercises in fighting inside buildings, although they have not practiced much, but the basic points are still remembered, the first one is the battle inside the building, and the main weapons are Type 96 pistols and *.

After preparing the weapons, the soldiers of the 1st platoon immediately launched an assault on the War Department building of the Kanto Governor's Office under the cover of fire from other troops, and only two soldiers were shot in the whole process, and when approaching the gate, the platoon commander Liu Fuxi first threw a * into the door, and when the smoke of gunpowder had not yet dissipated, he rushed into the gate with the deputy platoon commander Wang Litian, and raised the Type 96 pistol, regardless of 3721, it was a burst of random fire, which is also the basic principle of the internal battle of the building, that is, * open the way, plus random fire suppression.

After the smoke cleared, all the soldiers of the 1st platoon entered the building. The Kanto Governor's War Department building is symmetrically arranged on the left and right sides of the central axis, with the entrance and lobby in the middle of the building, the staircase on the opposite side of the lobby, and a long horizontal corridor in the building, with rooms distributed on both sides of the corridor.

Liu Fuxi immediately ordered the 1st shift to be responsible for cleaning the room on the left side of the lobby, the 2nd shift to be responsible for cleaning the room on the right side of the lobby, and the 3rd shift to guard the lobby, and to respond to the 1st and 2nd shifts, so that they could block the Japanese soldiers upstairs.

At this time, several Japanese soldiers on the second floor wanted to go downstairs to join the battle, but as soon as they appeared, they were killed by a burst of random shooting by the People's Army, so the Japanese soldiers on the second floor did not dare to go downstairs easily.

The soldiers of the two squads attacking the left and right rooms were divided into two parts, led by the squad leader and deputy squad leader respectively, and attacked the rooms on both sides of the corridor.

At this time, the doors of all the rooms were closed, and only in front of the door of the first room on the left, a squad leader stood with a Type 96 pistol, a soldier holding a rifle in his hand, holding a gun in a half-crouching position, the position of the two men was slightly on one side of the door axis and at an angle of 45 degrees to the door, and on the side of the doorknob, there was also a soldier holding a * and standing against the wall. Then one of the soldiers kicked the wooden door with his foot, and after kicking the door open, the two soldiers on one side of the doorshaft immediately fired a continuous fire, suppressing the soldiers in the room, and the soldiers on the side of the doorknob pulled the string* and threw it through the door.

After the explosion, the KPA soldiers entered the room, only to see 4 or 5 Japanese soldiers lying in the room, and 2 or 2 Japanese soldiers who had not yet lost their breath, but they were also injured in many places and screamed miserably. The KPA was also not polite, stabbed each of them twice, completely ending the lives of the two Japanese soldiers, and then exited the room and attacked the next room.

This set of tactics was of course taught to the KPA by the crossing soldiers, and it was actually one of the anti-terrorist tactical training programs in the old room. Although it seems simple, it is actually a tactic summed up from countless similar battles, and it is quite effective in actual combat. Although the Marine Corps is not a professional counter-terrorism unit, it will also train some counter-terrorism tactics, after all, counter-terrorism warfare was one of the main forms of warfare before the crossing.

Of course, the KPA has embraced simplified tactics, but in this era, it is completely sufficient. In contrast, the performance of the Japanese army can only be described as amateurish, although the quality and actual combat experience of the Japanese army are above the KPA, but the small-scale battles in this kind of building are quite epiphytic, so under the tactical attack of the KPA, room by room was cleared.

Of course, the KPA's clean-up was not all effective, some rooms did not have Japanese soldiers, some rooms were non-combatants, and some rooms had a large amount of furniture, so the effect was limited, and in the end the two sides had to fight to the death, but on the whole, the KPA still had a very obvious advantage.

And while the first platoon was clearing the rooms on the first floor, the second platoon also stormed into the Kwantung Governor's War Department building and launched an attack on the second floor, of course, the tactics were exactly the same as the first floor. The next three platoons also rushed in and attacked the third floor.

After about an hour of fighting, the KPA finally cleared all the rooms in the War Department building of the Kanto Governor's Office, killing more than 350 Japanese soldiers, including non-combatants, after all, in such a situation, accidental injuries were inevitable, 27 Japanese soldiers were captured, more than 200 non-combatants were captured, and only 8 KPA soldiers were killed and 21 were wounded.

The battle for the War Headquarters building in the Kwantung Prefecture had ended before that, and the KPA used the same tactics to successfully capture the Sino-Russian Dosheng Bank building and the General School Assembly Hall, eliminating most of the Japanese soldiers in these two buildings and capturing many non-combatants.

By this time, the People's Army had completely broken through the main Japanese position in the Lushun New Town, and had basically controlled the Lushun New Town, and the Japanese army had no large-scale positions in the New Town, and only some sporadic resistance remained.

However, compared with the smooth operation in the new city of Lushun, the People's Army encountered some minor troubles in the old city of Lushun.

After Luo Yue gave the order to attack, the 1st Division attacking the old city of Lushun was also relatively smooth, first successfully occupying the position of the Russian Lushun Kwantung Prefecture Governor's Mansion and Beiyang Hospital, and the attack on Lushun Prison was also very smooth, having broken through the Japanese army's defense line, entered the prison, and started a white-knuckle battle with the Japanese army, and had achieved obvious advantages.

Lushun Prison was originally built during the Lushun period of Russia, mainly to imprison Chinese who resisted Russian rule. After the Japanese occupied Arthur, it was used to hold Russian soldiers captured on the battlefield.

In the Russo-Japanese War in the early stage, the Japanese army captured a total of about 79,000 Russian soldiers, most of whom were sent to Japan for internment, and about 7,000 people remained in China, all of whom were placed in Arthur Prison.

It should be said that the Japanese treated the Russian prisoners quite well, treated the wounded Russian prisoners well, arranged a very rich diet for the Russian prisoners, and in order to take care of the taste of the Russians, not only provided a large amount of meat food, but also specially supplied Western cakes, chocolate and wine, and ate even better than the Japanese soldiers. In addition, the prisoners were given considerable freedom, not only in the prison can move freely, but also have one leisure time in the morning and one afternoon each day, they can go out of the prison and wander around the city of Arthur, because the appearance of the Russians is obviously different from that of the Asians, the language is not understood, and they are penniless, so they are not afraid of them taking the opportunity to escape, and some activities such as sports competitions, stage plays, symphonies, and so on are held regularly.

The reason why Japan treated the Russian prisoners well was nothing more than two points: First, it won the approval of the great powers, and Japan was a civilized person different from other Asian countries; second, the Japanese army abided by international law and had strict military discipline, and was a respectable army.

It was during the Sino-Japanese War of 10 years that the Japanese army caused the Lushun Massacre, which aroused unanimous criticism from public opinion in Europe and the United States Later, Li Hongzhang went to Japan to negotiate peace and was assassinated by Japanese radicals, which made the Japanese government very passive for a time, so in the future, Japan paid more attention to its own international image in foreign wars, and tried to make itself a civilized person.

In the Eight-Nation Alliance's war of aggression against China, the Japanese army had the best military discipline among the Eight-Nation Army, and this time Russia was facing an old European power, and despite the support of Britain, most European public opinion was still biased towards Russia before the war, and Japan paid great attention to these aspects, so it treated Russian prisoners very favorably, which even caused domestic dissatisfaction.

The KPA attack on Arthur Prison made the Japanese army flawlessly take care of the Russian prisoners, so the prison was in a vacuum, and the Russian prisoners could move freely in the prison, at this time most of the Russian prisoners instinctively felt that there was a chance, so they all went out of their rooms, a few people also picked up some weapons, and some officers took the opportunity to organize.

The People's Army that stormed the prison also quickly met the Russian prisoners, because the language barrier between the two sides, and during the war, the two sides could not communicate calmly and slowly, and because of the preferential treatment of the Russian prisoners by Japan, it also contributed to the superiority and arrogance of the Russian prisoners, in their opinion, although they were prisoners, they were also one level higher than the yellow race, so both the Japanese and the Chinese would salute themselves three points.

In a chaotic situation, it was not the side that fired first, which eventually triggered a fierce battle between the two sides.
