20 kilometers, which is basically a blink of an eye.

The attack wave continued to move forward, and the armies of Heavenly Cultivators and Ghost Cultivators continued to retreat, and at this time, they had all retreated to the front of the position.

"10 km more! All weapons ready! Highest level of defense! All logistics units are ready to replenish any supplies! All the machine gunners and gunners all take double posts! If someone is sacrificed, replace the next group immediately! Rotate every ten minutes! Stay ready to fight! This attack was unusual! Repeat! This attack was unusual! ”

Looking at the defense line, you can see far away, and the monster is no longer moving forward like an ocean, like a mountain, pressing up towards the defense line!

This is a completely different attack from the previous ones! The opponent directly created several times the previous offensive force on the attack surface that was exactly the same as the original, and pressed towards the side of the defense line!

Among the black-pressed monsters, some balls of various colors were constantly emitted: some of those balls were sent by the artillery on their side, and some were greetings from the Heavenly Cultivators and Ghost Cultivators when they attacked.

But whether it was the roar of the cannon or the devastating tricks of the Heavenly Cultivators and ghost cultivators, against the backdrop of the sea of monsters that seemed to be monstrous, they were like some small pebbles thrown on the huge waves, and they didn't play a big role.

Many Heavenly Cultivators had already returned to the defense line, and when they reached the back of the third layer of defense line, they were already directly paralyzed on the ground: their yang energy had already been exhausted.

But even so, the monster army didn't seem to have diminished at all: the monstrous black wave seemed to still be tens of meters high, which looked very amazing!

And now the distance is less than 10 kilometers.

Bai Fan and a few others all stood behind the defense line and looked over there, but Bai Fan still didn't capture the information he wanted to capture.

Those monsters, each of them is completely generated by yin qi, so in front of Bai Fan, the whole is a sea of yin qi, there is no way to find a place where yin qi is very concentrated, plus the other party seems to be deliberately concealing his yin qi, it is difficult for Bai Fan to find where there is stronger yin qi.

Everyone else also looked at Bai Fan: for Lady Liberty and Hua Song Li, Yin Qi was completely unfamiliar to them, and it was difficult for them to find the real place.

Thousands of artillery guns fired in unison on the defensive line.

Then, about five kilometers away, the anti-aircraft machine gun began to roar incessantly.

Although the anti-aircraft machine guns are not so powerful, they are too dense: in addition to the first line of defense, the second and third lines of defense are basically full of all kinds of anti-aircraft machine guns roaring, and the density of fire is unbelievably large.

If you look at it from the other side of the line, you will see that the back of the line is like a huge construction site: it is divided into seven floors from top to bottom, there is a huge cannon every fifty meters, and then there are machine guns everywhere, ant-like soldiers up and down, and large elevators constantly send tons of ammunition up, and the whole thing looks like an ant's nest.

At this time, there were still three kilometers to go from the defensive line.

At this point, the thickest distance of the defense line had been reached: the bullets and shells had almost become an iron wall, chewing everything that was close to the defense line, and the corpses of the monster army had piled up to almost higher than the first line of defense! And it's still getting higher!

Are these monsters trying to use corpses to get past the defenses? Now it seems that this trend is very much in place!

But the other party has been suppressed, there is no doubt about it.

"Looks like their tactics have failed! In this way, you will not be able to break through the defense line of the Great Wall! Lady Liberty said very seriously.

And everyone else basically agrees on the same opinion.

And Bai Fan still didn't say anything, but continued to observe.

Soon. The corpses became more and more in front of the position, almost piling up a slope, and then those monsters began to step on the corpses of their own people, almost using this slope to charge!

And this caused a certain amount of trouble to the Great Wall defense line.

Any firing weapon requires a certain range of shots: that is, the distance and range of the shot, and the opponent piles up a slope in front of him with a corpse. This made it difficult for many low-positioned machine guns to fire.

But now it is impossible to send a clean-up force out to clean up the corpses, so they can only continue to shoot, and the machine guns in the upper echelons are starting to play more roles.

And by this time, the monster army had approached the whole direction: they were almost using corpses as their armor, constantly extending towards the forward position.

This way of advancement, I'm afraid that only the monster army has this ability.

In the main direction of attack, the monster army was almost paving the road inch by inch with corpses, while Bai Fan looked ahead and watched the surveillance.

"This time they got under the line much faster than before, and the losses were almost a fifth of what they had before!" The statistician frowned and said, "Although their losses are increasing sharply now, they can still advance directly to the foot of the defensive line!" ”

Bai Fan frowned, and suddenly ordered: "Prepare emergency plan No. 1!" ”

This order took everyone by surprise.

Emergency Plan 1 is the one to be used in the most urgent situations: to confirm that the line of defense has been breached, and then to close the gap at all costs!

"Bai Fan, there is no trend of the defense line being broken now. What do you mean by that? Xiongjin looked at Bai Fan puzzled and asked.

Bai Fan shook his head: "It's not that simple! The line of defense will definitely be broken today! You're going to see it! I don't know exactly how it was breached, but it will! ”

Bai Fan's explanation was not clear, but everyone understood that Bai Fanjue would not talk nonsense, so he could only continue to watch, not knowing what would happen at that time, but he could only continue to watch.

At this time, basically the entire Great Wall defense line was fighting, but the main battle broke out on the great plains in the core area, and the other side was almost paving the way forward with his life: almost inch by inch.

Although it was very slow and slow, it was still tenacious and unyielding towards the defense line little by little.

Everyone was shocked when they looked at it: if they fought like this, of course, they would eventually be able to get under the defense line, but the sacrifice they would have to pay was probably unimaginable for the monster army!

"If they're going to break through the defense, let them break through like that!" Everyone is one evaluation.

And that's when things suddenly changed!
