A single cannonball rained down on the ground, and there were thirteen or fourteen above the trench where the wolf was located, and four or five more fell directly into the trench where they were.

These shells were bubbling white at this time, and all the devils stopped swinging their shovels almost instantly, and their faces showed infinite horror.

Only then did they know and immediately screamed in horror.

Sadao Ushijima and Hiroshi Nakagawa were both holding binoculars and watching the engineering units on the battlefield, and shells suddenly fell from their binoculars.

After that, the sappers in the entire trench became frightened and confused, and the three highest-ranking commanders of the devils looked at each other, not understanding how so many shells could actually scare the soldiers on the position like this.

But just before they could figure it out, suddenly the devils in the trenches scattered and fled like crazy hares, and some of the devil soldiers even climbed up the trenches and ran wildly not far away.

This kind of behavior is simply looking for death, because they are already more than a hundred meters away from the fortifications, and exposing their bodies at this time is to put themselves under the fire of Qin Feng's troops.

However, these devil soldiers did not suffer from machine gun fire, because it was too late, and the moment the devil soldiers crawled out, a roaring explosion rumbled through the position......

In particular, the devil soldiers in the trenches were thrown into the sky like puppets in the violent explosion.

In the trenches on both sides, the shock wave of the shell explosion could not spread around, but could only impact in two directions, which made their shock wave more powerful as if it had been clustered.

The explosion of hundreds of bombs was almost like the roar of hundreds of heavy artillery shells.

However, it was so close to the first layer of fortifications that some of the explosives still fell into the trenches.

The ghost sappers who were crowded together were instantly shrouded in huge flames, and the small part of the devil soldiers who escaped from the trenches were directly torn apart by the dense explosion.

Call...... The intense explosion quickly subsided, after all, these shells were carefully designed, with a range of about one hundred and fifty meters.

Due to the different angles of the projectile, its delay time is also different, and Qin Feng set the delay to ten seconds.

But it usually takes five seconds to be fired, which means that these shells have burned for five seconds before they are ejected, stay in the sky for one to two seconds, and explode almost two or three seconds after they hit the ground.

Therefore, in the area covered by bombs, the devil has no hope of letting Li escape.

Whining...... A roaring wind whistled by, and the blood mist that was raised was directly blown away, revealing the appearance of the battlefield at this time.

Mess, mess, stumps and broken arms everywhere, blood and viscera falling to the ground in a mess washed by the blast wave of the explosion.

However, even if the explosion was very violent, it only destroyed the top part of the soil layer that was thirty or forty centimeters thick.

Even beneath the center of the explosion was still flat, and the human limbs and flesh and blood were glaring in the land.

And in the devil's trench, the surviving devil sappers were panicking and crawling towards the rear, and at this moment they didn't even have the courage to stay there for even a second.

The violent explosion of those shells was almost impossible to resist in the trenches, as long as the place was affected, the devils would immediately be swept away by the huge explosion, and the terrifying shock wave was almost enough to make people faint directly.

"Yaga!" The huge explosion also shocked Sadao Ushijima and Nakagawa Guangda, they didn't expect that the most ordinary cannonballs could burst out with such great power in Qin Feng's troops.

They looked at the last remaining barbed wire, and everyone was thinking about what to do next.

They all knew that now that the engineering troops had suffered heavy losses, and Qin Feng was able to use such an attack method once, then he would use it a second time.

Of course, they also knew that such weapons would be very dangerous for them to attack later, because they had to continue attacking the second barbed wire.

However, the barbed wire fence was only about a hundred meters away from Qin Feng's fortifications, and such a distance would definitely cause them to pay huge casualties when they attacked.

After all, they had seen the power of the explosion of the shells just now, and the violent shock wave that hit the explosion could also cause huge damage to their soldiers.

Especially at a five-meter radius of the shells, it is almost impossible to escape, once the dense shells all explode, the terrifying impact formed by the shock wave in an instant is enough to tear countless devil soldiers to pieces.

However, just when all the devils were in a dilemma and were afraid of the cannonballs in Qin Feng's hands, Nakagawa Guang looked at the trench that had been dug up to a small amount, and there was a glimmer of light in his eyes.

"We can use heavy bomb canisters to bombard the defense line of the Chinese people, and the artillery defense of the Chinese people must be extremely weak.

And our heavy projectiles can project a distance of 300 meters, which will be difficult for the Chinese to resist, and the infantry can take advantage of this opportunity to attack. "Nakagawa Hiroshi is worthy of being a seasoned commander, and in an instant he discovered the weakness of the defenders.

When he saw the devil's mortar unit start to move towards them, a cold light flashed in Zhao Jinwu's eyes.

He didn't expect that there would be such a smart person among the devils who could see his weakness at a glance, and immediately ordered all the troops to withdraw, these defenseless weapons, as well as those naked shells, once they were concentrated by artillery fire, the consequences would be unimaginable.

But in Zhao Jinwu's opinion, if the devil wants to use such a trick to overcome the fortifications, it is simply a fool's dream, after all, the power of the mortar bombardier is just like that.

Even the so-called heavy projectiles can't do much damage to the cement fortifications at all, and the devil's attack at this time is completely looking for death.

However, the devil didn't think so, and the devil at this time was bent on destroying the second layer of barbed wire.

They had already planned their operations, and the devil's first goal was to destroy the barbed wire fence and then take down the first layer of fortifications as much as possible.

Then they continued to attack the second layer of fortifications, they had one advantage of their own, that is, troops, they could afford huge losses, while Qin Feng's troops only had two layers of fortifications.

After the destruction of the two-story fortifications, Qin Feng's troops will have no way to retreat, and at the same time, the strength of Qin Feng's troops is too small, once the casualties are huge, then the strength will be difficult to maintain.
