Yamaguchi was brave and had a good mind. Judging from the failure of the first charge, Yamaguchi understood immediately that the key to taking down the Buyunshan position was that it had to break through the barbed wire in front of the trenches.

As long as these annoying barbed wire fences still exist, his soldiers would not be able to rush to the enemy as quickly as possible and perform the bravery of the Great Japanese Imperial Warriors. Because of the barbed wire fence, the Chinese could hide in the trenches and comfortably use machine guns and other weapons to easily tear the brave soldiers to pieces. In response to this point, Yamaguchi Katsu immediately concluded that the barbed wire fence must be solved, and the continuous bombing just now was also for this purpose.

The shelling was very moving and the attack was very fierce, but the result was not very good. I observed the front position of the next Buyun Mountain through a telescope. Yamaguchi ordered the artillery and artillery to be suspended. Now the commando covers the engineers and starts attacking. Since the cannon cannot be used to solve the problem, then let's see the engineers.

In the telescope, Sun Liechen clearly saw that the Japanese soldiers rushing up this time were completely different from the last time. Nearly a hundred Japanese soldiers who did not have weapons were carrying ladders or wooden boards for climbing the city, and some were carrying bulging sacks that were probably filled with soil on their shoulders, rushing towards the front of the position quickly.

"Damn little Japanese!" Sun Liechen was a little surprised and instantly understood what the Japanese were trying to do. Using ladders, wooden boards and earth bags to deal with the blocking of the wire mesh, this method seemed a bit simple, but the effect was not bad. As long as the Japanese could press these things on the wire mesh and pave a way forward, their advantage in front of the trenches would be gone.

"Machine gun! Mortar! Grenade launcher ready immediately!"

Zhang Zuoxiang, who also reacted, hurriedly issued an order, in order to defend the defense line, he could not let the Japanese succeed in any case. Faced with such a situation, he even used unused mortars, grenade launchers and other weapons in advance. You must know that these treasures were originally planned to be used in critical situations, in order to hit the opponent with a surprising surprise. But now, Zhang Zuoxiang knew that it was not the time to hide his weakness. If the Japanese could not stop the attempt, his defense line would face the point of fighting directly with the opponent.

Eight hundred meters, seven hundred meters, six hundred meters....

In just a few dozen seconds, the Japanese army's charge was almost in front of him. When the Japanese army rushed to a distance of 500 meters, the ready-made machine gun positions first began to strafuse, although many Japanese soldiers were defeated in an instant. However, the engineers who were covered by the commando did not suffer too many casualties.

"Quick! Quick! Quick!"

The commando squadron leader shouted anxiously, directing the accompanying machine gun to mount the machine gun to suppress the opponent's firepower, and urged the engineers to move forward quickly.

It may be easy to run for nearly a thousand meters with empty hands, and it is not a big problem to run with weapons. However, the engineers are not combatants, and they are carrying so many "tools" on their shoulders. It is not so easy to quickly rush through the fire blockade to reach the destination. Although there is a cover from the commando, as they get closer and closer, the casualties of the engineers gradually begin to rise. Seven or eight engineers fell down in just a distance of nearly 100 meters, but the remaining engineers didn't look at their comrades hit by bullets. They gritted their teeth and rushed forward desperately.

Fifty meters, forty meters, thirty meters...

It was about to reach the barbed wire, and the entire commando team had more than 50 casualties during this journey, but everything went smoothly. They were finally about to reach their goal. As long as they could complete the task, all the efforts were worth it.

Suddenly, a sharp and strange howling sound broke through the sky, and dozens of small black dots flew from behind the Zhong** team's position to the charger at a speed visible to the naked eye.

"What is this?" Several guys who were fast-footed had rushed to the barbed wire. The engineer who was about to put the ladder and other objects on it subconsciously looked up, and a puzzled thought passed through his mind.

If you want to talk about shells, the shells seemed a little smaller, and they didn't hear the earth-shaking roar of the cannon just now. But if it weren't for shells, why did the Chinese throw these things? Are you planning to use this iron block that is not much bigger than a fist to kill them?

Time was only a moment. Before these guys could figure it out, mortar shells and grenade distillation bombs fell to them. With the sound of not too violent explosions, the soldiers who squeezed together were blown up. A few unlucky guys were thrown into the sky with the wooden boards they carried, accompanied by a piece of broken flesh, wood, mud and other garbage scattered everywhere like raindrops.

"Bombardment! It's shelling! The Chinese have cannons!"

The soldiers with courage were afraid of being covered by cannons. Although the Chinese cannons seemed to be different from the familiar cannons, they could also kill people. What scared the Japanese soldiers even more was that at such a distance, the cannons could not adjust the angle and land on their heads, but the Chinese cannons did this and were shot extremely accurately, which made the Japanese soldiers feel scared.

Mission is important, but life is equally important. It is almost impossible to complete the mission under the threat of shelling. Amid the sound of gunfire, neither the commando nor the engineers no longer care about dealing with the barbed wire. They threw down the rag in their hands and hugged their heads and ran back desperately. In a short while, in addition to leaving nearly a hundred corpses in front of the position, the 10th Division's attack was beaten back again.

"Nani? A small cannon that can shoot in a curve?" Yamaguchi was extremely annoyed by another failure of attack that he felt that he could make a breakthrough. When he learned that the Chinese actually had a strange cannon that could hit close range, and was particularly fast and accurate, Yamaguchi Kazuki couldn't believe his ears.

"This is impossible! How could the Chinese have such a weapon? It is absolutely impossible!"

"Your Excellency, maybe it's possible." Just when Yamaguchi Katsuki was angry, Chief of Staff Major General Kim Kubo Wanji reminded him: "When our army attacked the second line of defense, the Chinese army fired such shells, but we did not find such cannon during the capture."

"There is such a thing?" Yamaguchi Katsuki was stunned.

"Yes!" Jin Kubo Manji nodded with a serious expression: "Your Excellency, because the opponent's shelling only a few times at the beginning, the losses caused to our army were not great, so the front-line combat corps did not report it as an important matter. However, as the Chief of Staff, I once heard about this from a subordinate, but I didn't care too much. You, today's failure of the offense, I should bear the responsibility. This is a serious dereliction of duty as the Chief of Staff."

After saying that, Kim Kubo Mangye stood attentively and bowed, waiting for Yamaguchi Katsu's reprimand.

"It's not your fault for this, Jin Jiubaojun. Please ask the soldiers who were fighting at that time and ask them to verify whether they had encountered the same weapon as the soldiers who had just retreated." Yamaguchi Katsuya did not angrily scold the other party, but thought about it thought about it and ordered.

"Hi!" Jin Kubo Manji quickly turned around and left. After half an hour, he rushed back and told Yamaguchi Katsushiro that he had verified that whether it was the launching status of the shells or the sharp sound of the empty space, it could be concluded that the Chinese side did possess such a strange weapon, and there seemed to be two types of weapons, one was slightly larger and the other was slightly smaller. Although the power was not very good, the launch speed was very fast, and it was likely to cause big trouble to his side when attacking intensively.

Yamaguchi Katsuki, who got the answer, didn't say anything for a long time. After a long time, he decided to suspend today's attack. After all, it was almost evening, and the troops were blocked from rushing all the way, so I could find a way to do it the next day.

This night was a peaceful night. It was rare for the 10th Division to not continue the attack at night. The Central ** team, which had a breathing time, was not idle. They continued to improve the fortifications under the command of Zhang Zuoxiang and prepare quickly.

When the sun rose the next day, the 10th Division, which had been resting overnight, began a new day of attack. After considering the whole night, Yamaguchi Katsu decided to adjust his offensive tactics again. He changed the methods of the Japanese army's intensive charge in the past, and broke the attacking troops into pieces, and brought some engineers to attack repeatedly, and still used the ladders, wooden boards, and mud bag tactics he had prepared to deal with the damn barbed wire set up by the Chinese.

The 10th Division, which adjusted the offensive tactics, encountered trouble on the Chinese side. Although each attack could cause some casualties to the Japanese, due to the scattered forces charging different groups, in other words, the Chinese side suffered some losses in ammunition consumption and lethality. Moreover, facing Yamaguchi's "ant moving" strategy, the effect of mortars and grenade launchers also decreased a lot. As the Japanese advance little by little, Zhang Zuoxiang was so anxious that he was sweating.

"Mom, let me slap! Get a cannon for me! Get a cannon!"

The barbed wire before the Buyunshan defense line was twenty meters wide. From morning to noon, the Japanese army used this tactic to push forward by nearly eight meters. If the Japanese still could not stop such an attack, the barbed wire in front of the trench might lose its effect before darkness arrived.

Both Zhang Zuoxiang and Sun Liechen were unwilling to see this scene. In order to stop the Japanese from advancing, the mortarist and grenade launcher fired hundreds of shells and distillation bombs, but the effect was not significant. Apart from killing dozens of Japanese soldiers, the Japanese still could not stop. Seeing this result, they were anxious.

"In this case, the power of mortars and grenade launchers is too small. If we have heavy artillery, we can directly break the little Japanese rags." Sun Liechen said.

"Nonsense, don't I know?" Zhang Zuoxiang gave him a blank look. If he had heavy artillery in his hand, he could make the other party so arrogant? A few shells were taken to keep the Japanese lay on the wire mesh, then the guy was completely ruined.
