In the face of the assault team, the little devil defense line guarding the back street was broken, and many little devils died under the guns of Wang Si and their charge.

But Kozuka was unwilling to retreat from Yucheng like this, so he reorganized his forces, refilled the gap that had broken through, and then increased defensive firepower.

The light and heavy machine guns that defended the backstreet were only half of Kozuka's team before, but now seeing that the situation was critical, he had no choice but to transfer all the remaining light and heavy machine guns to the front line, and blocked Wang Si's charge with the advantage of powerful firepower.

The dense sound of machine guns and the sound of constantly exploding grenades, combined with the burning smoke, covered the entire backstreet battlefield.

Before the brothers who had just rushed over could gain a foothold in the enemy position, they were immediately counterattacked by fire and were beaten back.

In this way, the devil's defense line that had just broken through was once again returned to the hands of the devil, and after the commando team consumed so much ammunition, it returned to the original point again, and nothing changed at all.

"Fourth brother, as soon as we rushed to the enemy's position, we were hit by the strong firepower of the devils, and the brothers really couldn't beat it, so they had to retreat back in the end." The big man retreated and found Wang Si as soon as possible to report the situation encountered in the battle.

"That's right, our brothers originally thought that those heavy machine guns had all been destroyed by our mortars, but they didn't expect that the little devil still had heavy machine guns!" He Guoqing added at this time.

The brothers were suffering heavy casualties under the machine guns that suddenly appeared on the little devil's side, and he was reluctant to count the casualties, and he felt terrible to death.

"It seems that the little devils are ready for the second hand, leaving some light and heavy machine guns as a backup, after our mortars blow up their heavy machine guns, they can quickly transfer the remaining heavy machine guns to the front line, and resume the previous battle." Wang Si speculated, it seemed that only this explanation could explain everything in front of him.

You must know that when the mortar artillery covered the devil's machine gun array just now, he saw those heavy machine guns blown up with his own eyes, and the devil was able to recover his combat effectiveness so quickly, there seems to be only one explanation.

"If you don't let Lao Chu and them shell the devil's machine gun again, I don't believe that the little devil will have a backup!" Jiang Caidie suggested at this time.

Otherwise, they could destroy the devil's machine gun once, and it wouldn't be difficult to destroy the second time, so she believed that as long as Chu Huaichen and Ma Sancang did it, no matter how many machine guns the devil had, they would be blown into slag.

"Lao Chu, what do you think?" When Wang Si heard Jiang Caidie's suggestion, he immediately turned around and asked Chu Huaichen beside him. It is his basic mercenary principle to know that the artillery must be asked about the shelling before making a decision.

"We don't have many shells left, after this round of shelling, it will mean that the artillery in our hands can no longer sound, and when our assault team arrives at the front line in Changsha, I am afraid that we will have to rely on the burning sticks and devils in our hands to fight hard." Chu Huaichen was very light about the shells of their mortars, so he said honestly.

"Fourth brother, you have to hurry up and make up your mind what to do, Chief Song and their large army are behind us, and they will soon arrive at the back street!" The big man was a little anxious, he knew the current situation, they didn't have much time to delay, they had to cut through the mess quickly, otherwise they would wait for Chief Song and their troops to arrive, and their task of opening the road had not yet been completed, which would make people feel that they were incompetent.

"In this way, I order you to shell the devil's position one more round, take the devil's machine gun position with the least number of shells, and cover our main force to rush up!" Wang Si also knew their current trouble, and knew that delaying it would cause the large army to delay the fighters, so he decisively gave an order and said to Chu Huaichen.

"Yes...... Mission completion guaranteed! Hearing Wang Si's order, Chu Huaichen immediately responded, and then returned to the mortar with Ma San Artillery in time and began to adjust the direction of the shelling.

This is a basic requirement for the accuracy of shelling, and they must achieve the highest accuracy so that they can avoid wasting shells.

This time, they had very few shells and tested firing every day, so the requirements for calibrating the left and right levels were even higher, and the two of them did not dare to slack off in the slightest and did their best as they could.

After a period of debugging, the Ma San Artillery first gave a thumbs up, indicating that the preparations had been completed and that it was time to load the shells.

In less than a while, Chu Huaichen also gave a thumbs up, and his preparations were done, just waiting for Wang Si to give the order to open fire.

Seeing that they were ready, Wang Si got up, raised his right hand at my two mortars that were ready for shelling, and then threw them down from top to bottom.

Chu Huaichen and Ma Sanpao each picked up a shell and slid down at the muzzle of the mortar, and immediately heard the sound of the shell scraping the barrel, followed by two loud bangs, and the two shells flew into the sky under the flames spewed out from the muzzle and smashed into the machine gun position of the little devil.

The devil's two heavy machine guns were shelled almost at the same time, and the powerful artillery fire instantly covered the devil's position, blowing up the little devil's machine gun on the spot, and the devil's machine gunner also pushed the position out of the position with huge thrust and fell to the ground.

Then, as the second shell was loaded into the muzzle, two shells streaked through the air, and then the first two shells flew over and smashed on the other two heavy machine guns of the devil.

The Devil's machine gunner was blown to the ground along with the heavy machine gun, destroying the Devil's heavy machine gun position on the spot.

At this time, Wang Si personally led the brothers to rush towards the front of the devil's position, and kept shooting at the little devils in front of him to ensure that their charge was unimpeded.

Kozuka didn't expect Wang Si's counterattack to be so fast, he thought that after Wang Si's cannonball hit one round, it would turn into scrap copper and rotten iron because there were no cannonballs, but he didn't expect this cannonball to come so quickly, and instantly destroyed four of his heavy machine gun positions in the front.

Many of the little devils around him also died on the battlefield, and with the 38 big covers in their hands, they couldn't stop Wang Si and their charge at all.

"Your Excellency, retreat quickly, the Chinese army has already rushed up, and if we don't leave, we won't have a chance to leave!" Hashimoto said to Kotsuka at this time, and helped Kotsuka to leave as soon as possible.

"Yaga, a samurai of the Great Japanese Empire, even if he dies in battle, he can't do such a degrading thing!" Kotsuka refused to leave, struggling to push away the two devil soldiers around him, but none of those devil soldiers let go and forcibly took Kotsuka away from here.

Takahashi then gave the order to retreat, and all the little devils followed Takahashi and walked towards the south gate.
