"Boom" A dazzling ball of fire suddenly burst out in front of him, Kuroki only felt a heat wave in front of him, and in shock, Kuroki tried to lower his body and shrink to the corner of the wall, but he was directly lifted up by the rushing air waves. Along with the two companions behind them, the Kuroki trio were pushed against the wall behind them by the blast of air, and then were blasted out of a large cloud of blood mist by the flying fragments. * Before the dust dissipated, Lu Yuan in the corridor had already rushed into the room.

"Smack... Syllable... Lu Yuan, who appeared in the room in a flash, didn't care at all about the rifle that had been raised in the hand of the Japanese soldier on the windowsill, but just shot the other party down from the windowsill with one shot, and then turned the muzzle of the gun and replenished the guns one by one for the other Japanese soldiers in the room. Dong Peng and others, who were left on the 4th floor by Lu Yuan, heard the rapid gunshots coming from downstairs, so they immediately followed Lu Yuan's instructions and threw down two * bags from the window.

"Boom" "Boom" There were two loud noises downstairs, and the ladder erected by the Japanese army under the outer wall was immediately destroyed by the explosion, and the Japanese soldiers on the ladder could only cry wolf and fall heavily to the ground. The sudden change made Suzuki Sausai and others who were watching the battle from a distance look dark, especially Suzuki Saushiro, who couldn't understand why the opponent had so much ammunition and equipment.

Lu Yuan, who was alone on the second floor, had already cleaned up two rooms in a row at this moment, and two bullet holes finally appeared on the sleeves of his military uniform. Luckily, he was not injured by the bullets fired by the Japanese army, but Lu Yuan was shocked into a cold sweat, and now it is not the time for the operation to be suspended, and Lu Yuan, who still needs to maintain strong combat effectiveness, does not want to lose his combat effectiveness so early. "Keep on the offensive and make sure the battle ends before dark." Suzuki Sasai, who was watching the battle from a distance, was also beaten out of anger and immediately ordered to increase the intensity of the attack.

After all, the Japanese army had the advantage in numbers, and once they made up their minds to attack, the Japanese army immediately broke out with a strong fighting spirit. A large group of Japanese soldiers rushed in through the main entrance of the building, and while Lu Yuan was busy cleaning up the Japanese soldiers in the room on the second floor, these Japanese soldiers who rushed into the large regiment on the first floor began to build a ramp under the broken stairs using bricks, rubble, tables and chairs. Although the ramp is not fully connected to the second floor, as long as you go up to the ramp and run, as long as you are a normal person, you can jump from the ramp to the second floor without any effort.

With this slope, the Japanese army continued to climb to the second floor, while Lu Yuan was alone, and there was no way to resist the attacks of so many Japanese troops at the same time. "Boom" "Boom" The * thrown by the Japanese army burst out in the corridor continuously, and the huge impact force of the head-on collision made Lu Yuan, who was hiding behind the bulletproof shield, tired to cope. With the * fragments splashed by the explosion, although it did not pose a threat to the bulletproof shield, the shock wave after the explosion consumed a lot of Lu Yuan's physical strength and energy.

In desperation, Lu Yuan had no choice but to retreat into the room behind him, and then stepped on the tables and chairs that had been prepared a long time ago, and climbed back to the third floor through the temporary holes. Lu Yuan seemed to have given up on the 2nd floor, but in fact it was not, Lu Yuan, who returned to the 3rd floor, immediately took out several melon-sized holes in the corridor floor on the 3rd floor, and then threw them down continuously from these holes*.

In just a few breaths, explosions rang out in the corridor on the second floor, and the Japanese soldiers who had completely occupied the second floor were caught off guard and were killed and wounded in the continuous explosions. "Nani? They dug holes in the ceiling? When the news came back, Suzuki Saonishi was shocked, this was only to the second floor, and there were also the third and fourth floors above, and if the enemy had drilled holes in the ceilings of all the corridors to drop * and *, then the next battle would be even more brutal.

As the battle progressed, the situation was indeed as Suzuki Saonishi expected, Lu Yuan firmly guarded the 3rd floor, and used those holes in the floor to keep throwing * and * to attack the Japanese troops downstairs. Lu Yuan's throw* has a variety of ways and means, some * will fall directly at the feet of the Japanese army, and some * will be tied to a rope by Lu Yuan and will unexpectedly explode on the top of the Japanese army's head.

Finally attacked the second floor, but the Japanese army had to pay heavy casualties and losses, but Lu Yuan took the opportunity to throw down the * bag from the staircase, turning the slope that the Japanese army downstairs had worked hard to build into useless ruins. The battle continued, but the Japanese troops who continued to attack had to once again erect ladders under the outer walls, and the Suzuki Brigade, which had been ordered to ensure the appearance of the headquarters building intact, could only attack in this way.

As the minutes passed, the soldiers of the Suzuki Brigade could only attack the second floor, but as the Japanese casualties increased, Suzuki Sasei immediately reported his proposal to the top of the dispatch army. Before the new order from the top of the dispatch army could be returned, the impatient Suzuki Sausai began to convene a meeting of his officers, "We can't go on like this, if we want to take care of the headquarters building, we will have to pay more casualties and losses, and it is possible that the entire Suzuki brigade will be filled in." ”

As the commander, Suzuki Zosai should not have said such words from his mouth, but all the people present were his confidants, and Suzuki Zuoxi didn't have to worry that someone would spread his words. Suzuki's words aroused the approval of all the officers present, and the Suzuki Brigade, which has always been the main force in attacking the fortification, has never fought such a breath-holding battle. The dispatch military top brass asked them to deal with the enemy in the building, and they also asked them to ensure that the headquarters building would not suffer too much damage, which was simply impossible, and if it weren't for this, they might have already eliminated the enemy in the building.

He and his officers quickly agreed that all Suzuki had to do now was wait and wait for the new orders from the top brass of the dispatch army. As time passed, Lu Yuan and the others, who did not see the Japanese army continuing to attack, seized the time to recover their strength or set up obstacles, because they knew that perhaps the next attack of the Japanese army would be the last battle. Suzuki's wait was not in vain, and after reading the report submitted by Suzuki Sasai, after they confirmed the casualty figures of Suzuki's brigade, they had to agree to Suzuki's suggestion and immediately revise the previous order.

"Ladies and gentlemen, the dispatch army has revised the order, and the next thing is up to us." Suzuki Sazai, who got the new order, changed his impetuousness just now and returned to the wise look in the minds of his subordinates. "The infantry artillery will be tested immediately, to ensure that the shells of the infantry artillery hit the preset target position, the opponent's combat effectiveness is very strong, and it has a variety of high-power weapons, the attacking troops must be careful to launch an attack with the support of covering fire, and remember to attack blindly."

Suzuki's order was quickly conveyed, and the soldiers who participated in the attack were busy preparing, many of whom did not even carry bayonets on their waists in order to save their strength and lighten their loads. Thirty Japanese soldiers, armed only with rifles and 30 rounds of ammunition, were quickly assembled, and they would be the main body of the attack, launching a new assault on the headquarters building under the cover of light and heavy machine guns and infantry guns behind them.

Although the first shell was only a test fire, the Japanese army fought as seriously as it did, and with just one shot, it turned a window on the third floor into a big hole. Lu Yuan and the others in the building were all shocked, the Japanese army actually began to use infantry artillery, it seems that this time it is more than lucky. "Come out of the room, as I told you, just keep the hallways and stairs." Lu Yuan didn't explain too much to Dong Peng and the others, just hurriedly said a few words, and immediately went down to the 3rd floor to wait for the Japanese army to appear.

"Boom" and "boom" accompanied by the violent explosion of Japanese infantry artillery shells, the headquarters building shook incessantly, and the Japanese troops outside the building also took the opportunity to speed up the speed, with the intention of taking the headquarters building in one fell swoop. Lu Yuan hurriedly opened his full-view map, and found that the red dots from far and near were densely packed with more than 200 people. With such a large number of enemy attacks, Lu Yuan immediately dispelled the idea of going down to the 2nd floor, and in this situation, it seemed that it was the best choice to stay on the 3rd floor and wait for work.

In fact, Lu Yuan never underestimated his opponents, when he went south, even in the face of the best traitor in plainclothes, Lu Yuan would still do his best, lest he cause a big disaster because of his own small negligence. Now, Lu Yuan needs to face a Japanese army that is much stronger than the traitor's plainclothes, and he doesn't dare to take it lightly. With the help of strong fire from behind, a large group of Japanese soldiers rushed into the building, and the long ladder they brought into the building was quickly erected, and immediately Japanese soldiers cautiously entered the second floor along the long ladder.

Waiting for Lu Yuan, who was in the corridor on the 3rd floor, he slowly pulled off the safety bolt of *, and after knocking * on the floor, the smoke* was stuffed into the hole in the floor by Lu Yuan's hands and feet. "Boom" fell through the hole on the second floor* exploded above the heads of the Japanese soldiers, and several Japanese soldiers who had just entered the corridor on the second floor fell in a pool of blood. Lu Yuan, who has a full-view map in hand, can accurately lock the opponent's position without revealing his position, and his advantage is extremely fatal to the Japanese army who attacked the building.

The Japanese soldiers on the first floor continued to follow the long ladder to enter the second floor, and the stairs between the second floor and the third floor had already been blown up by Lu Yuan, and the Japanese army wanted to go up to the third floor, so they still had to continue to erect the long ladder, but Dong Peng and others, who were guarding the corner of the stairs on the fourth floor according to Lu Yuan's arrangement, would not give the Japanese army this opportunity. The Japanese troops who stormed the building had no choice but to reinforce and extend the length of the ladder outside the building, trying to climb directly from the outer wall to the third floor.
