The rumbling explosion instantly swept across the entire charge commando, with powerful flames burning, and the bounced mud and sand rolling at the legs and feet of the brothers.

But the brothers quickly squatted down, covered their bodies with sandbags as much as possible, and lowered their heads slightly. After the Japanese grenade exploded, they slowly stood up and slowly moved towards the front.

Two or three brothers were injured by shrapnel that exploded, but they were not in danger of life. They still insisted on dragging their injured body and continued to advance forward.

Seeing that Wang Si and his team's attack could not be stopped, the Japanese continued to shoot at the commando in frightened manner, but except for punching a few holes in the sandbag, it seemed that there was no other effect.

The brothers advanced all the way, and when they reached the range of forty meters, they quickly built up the sandbags in their hands one by one, forming a simple protective wall.

The brothers all hid behind the protective wall, held the flower mechanism in their hands to cover the bomb drop team, and used the firepower of the flower mechanism to suppress the heavy machine guns of Huizi, hoping to win the bomb drop team time to drop bombs.

Without hesitation, the bomb-dropping squad rushed over immediately, concentrated all the remaining grenades of the commando, and threw them at the Japanese four 92-heavy machine guns in different positions.

The grenades were like small steel cannons in the hands of the bomb dropping Anban, directly hitting the target to be blown up, followed by a rumbling explosion.

The violent explosion overturned the Japanese heavy machine gun and killed the Japanese machine gunner on the spot. Four machine gun positions were instantly burned by fire, and the heavy machine guns were also destroyed.

All the Japanese machine gunners lost their lives in the explosion of grenades, and the first line of defense that stood in front of Wang Si and the others was successfully broken through.

Because of the effective cover of the commando, four Japanese Type 92 heavy machine guns were destroyed. The main force of the guard regiment quickly launched a charge, followed up with the first line of defense, and looked close to the Japanese's second line of defense.

Wang Si asked the commando to stick to a line of defense, stabilize the position, and wait for an opportunity to rush up to seize the second line of defense of the Japanese, open the East City Gate, and attack the East Gate of Jiangcheng.

But the guard commander couldn't wait. After seeing the front-line position, he couldn't wait to lead his team to attack the Japanese's second-line position and rush across the moat.

Just as the brothers rushed towards the second line of defense of the Japanese, they were attacked by the Japanese Burrow. When the machine guns inside the Burrow shot at the stormtrooper through the shooting port less than ten centimeters from the ground, more than twenty brothers from the guard group died heroically without any warning.

The remaining brothers quickly retreated under the leadership of the guard commander and returned to the front line of the Japanese positions they had occupied before.

"Damn the Japanese, I actually prepared three secret castles for me in front!" The retreating guard commander said immediately. It was obvious that he was so angry that he gritted his teeth at these Japanese.

"What's going on?" Because it was quite chaotic just now, and the tops of the castles were close to the ground, all the Japanese were almost in the strata, and Wang could not see the real situation at all. At this time, when he saw the guard commander and others retreat, Wang Si couldn't wait to ask.

Although the guard commander was talking to himself about the secret castle, he couldn't tell it clearly, and Wang Si didn't understand what was going on, so Wang Si had to ask in person.

"The little Japanese are so cunning. They actually opened a pit on the ground and made a bracket and lid with reinforced concrete. The Japanese hide in such a castle and shoot at our brothers who charge through the shooting port. The brothers were killed and injured!" When the guard commander heard the inquiry, he told him what he saw without any reservation.

"Are you saying that those castles are underground?" Hearing this, Wang Si immediately felt that things were not simple. It seemed that the Japanese had done a good job in the defense here and had been preparing for a long time, otherwise there would definitely be such a solid and hidden defense.

"Yes, I observed carefully. There were three people who fired at us, but I'm not sure if there were any such castles!" said the guard commander immediately.

Obviously, he caused them to suffer a great loss because of the sudden nature of these creepers. Now he was still scared when he thought about it. He never expected that Yoshino, an old Japanese devil, would have such strict defense against Jiangcheng, and he would almost never give them any chance.

"The Japanese's castle is hidden underground, which increases the difficulty of our blow-up!" Jiang Caidie said, as if the second line of defense that the Japanese were connected to was not so easy to break through.

"No matter how hard or difficult it is, we must fight here! Jiangcheng is right in front of us. We can't just watch and rob anything!" Wang Si said immediately.

They had no choice in this battle. They had to fight this battle well and successfully break through the second line of defense of the Japanese to have the opportunity to take down Jiangcheng and open the road to Wuhan.

"But now the Japanese's castle is not a bunker on the ground. It can solve the problem by relying on explosive packs!" Cui Yaolin said immediately after hearing Wang Si's words.

In the current situation, even if they send people to rush over and use explosives to blow up the castle, it will probably be of no use. After all, the castle under the ground is huge at the level of stress, and even if they use more explosives, it will be difficult to achieve, let alone they do not have that much explosive.

"We can only lift the cover of the castle after approaching those castles, throw it directly into the castle with a grenade, and fundamentally blow the devils inside!" Wang Si thought about it carefully, feeling that this is the only way to do it right now.

"But there are machine guns in the castle, so it's not easy for us to get close to it!" The guard commander immediately said. In his opinion, things were far from as simple as they imagined.

They tried the charge just now, but before the brothers got close to the castles, they were defeated and the losses were still huge.

Now I will rush forward again, I believe the result will not be better than before. Apart from increasing the casualties, it has no other effect.

"We can only use the defense line when conquering the front line of positions, use sandbags as cover to cover our bodies, and then charge forward. However, this time we are relatively far away, and it will be considered complete if we have to reach the castle!" Wang Si said with certainty.

He knew that the Japanese in front of him had a strong defense, and it was impossible to break through easily, and they had to find a way to deal with it. Moreover, judging from the current defense of the Japanese, the Japanese's castle may have more than three discovered by the guard commander.

There may be six, or nine, or even more, but no matter how many there are, all they have to do now is to destroy those castles and seize the second-tier positions.

"We can't bring a large explosive pack in this kind of action, we can only use grenades!" Jiang Caidie agreed with Wang Si's statement, thinking that this is the only feasible way at present, but what we need to consider now is the number of grenades.
