Crossbowmen.

What's worse is that after retreating into the cave passage, the crossbowmen can no longer attack at will, and the rear formation cannot support the front formation. However, once the crossbowmen are weakened by a close attack, the gap between them is three

More than four times! This undoubtedly strengthens the determination of the vampires to hunt down!

It wasn't until the angels carefully retreated to the entrance of the cave that the situation changed slightly.

Under the command of Liu Yifei, the angels began to use the heaven patrol to summon creatures to block the entrance of the cave.

The small number of summoned creatures is just right here, while the angels are responsible for blocking the upper half of the passage, which is not too big. The front half attacks. The back half begins to quickly heal companions and the summoned creatures below.

Several undead servants who are good at summoning have been used to the extreme by Liu Yifei!

Compared to the summons from heaven, vampires are obviously more afraid of those huge numbers of undead cannon fodder! Because these guys can't suck blood, they can't ignore their attack power. Instead, they are starting to regain their disadvantage little by little by the Angel Corps.

But the enemy is not stupid either.

After realizing that the pursuit was hopeless, the vampires did not continue to fight. Instead, they retreated decisively and retreated to their stronghold again, waiting for the order to charge again...

This battle was like a short but fierce storm! It started suddenly and ended even more unprepared~

"Tch! That's why I said that I hate dealing with these commanded mobile troops. It's so troublesome..."

Liu Yifei sighed secretly, and finally had no choice but to exit the mine.

In this battle, Liu Yifei estimated that he beheaded at least four thousand vampires! He definitely weakened the enemy by more than one-tenth~

What makes Liu Yifei extremely heartbroken is...

Damn it!

More than four hundred strong crossbowmen died!

This is the result of Liu Yifei and the others' desperate efforts to protect him!

Otherwise, none of the more than a thousand strong crossbowmen who entered the cave early would even think of exiting!

However, despite this, this is still a result that Liu Yifei cannot accept!

Judging from the proportion, this seems to be a "reciprocal" war of attrition. Judging from the absolute numbers and total military strength, Liu Yifei has taken a huge advantage.

However, this was a failure for Liu Yifei!

The experience of strategic mode made Liu Yifei understand that if he wants to become stronger as he fights, he should not consider how to destroy the enemy as quickly as possible. Instead, he must learn to protect himself.

When the military strength cannot be replenished, unless it is a particularly important fighter plane worth fighting to the death, the first thing to consider is to protect yourself.

Because once the troops start to lose, even if it is small at first, a vicious cycle will soon form!

Because the weaker the total combat power of the army, the longer each battle lasts. The more severe the losses will be!

In this mission, it is obvious that Liu Yifei and the others are unlikely to get more supplements~

And now Liu Yifei lost more than 400 strong crossbowmen before the main dungeon was even opened...

Damn it!

This is strategic-level "direct firepower"! It is an important data that needs to be prioritized more than combat power!

Combat power means "the firepower output that the troops can cause", such as spearmen, the "combat power" after gathering into a group is very high.

But if you can't catch up with the enemy and are kited by the enemy, you will be like a zombie. No matter how high your combat power is, it is useless. If it cannot be converted into actual "firepower", it will just be the enemy's prey~

The advantage of long-range attack troops is that they are absolute "firepower troops" and can convert combat power into actual firepower output as soon as possible!

And this is especially true for the crossbowmen as a "strategic unit"!

Their value has been fully demonstrated in the last battle~

Such an important unit, Liu Yifei, only had 5,000 in total, and he suddenly lost more than 400...

Nima is still protected by angels and resurrected!

Otherwise, the casualties will at least double!!!

Liu Yifei was so anxious that he wanted to curse!

However, after thinking about it...Liu Yifei suddenly discovered a problem...

Will the enemy take the initiative to attack?

Hold!

Then why didn't their angels attack when they entered in the first place?

Liu Yifei seemed to have grasped some key and immediately started experimenting!

The third time, he brought five hundred light knights into the cave, adding and subtracting all the way. Even if the value fluctuated between one hundred and one thousand, the enemy did not move at all.

The second time I brought the Saints.

When the number of saints reached three hundred, the enemy decisively launched an attack!

Depend on!

Actually watching people order dishes!!!

But this time Liu Yifei and the others came prepared, but they didn't take advantage of them.

The Saints quickly retreated to the red channel. Immediately an angel called to block the door~

After repelling the enemy, Liu Yifei began to run around the cave again to lay out his plan...

The fifth time he entered the hole, Liu Yifei used a "life-threatening" style of play!

The three hundred saints still retreated into the passage immediately, but they didn't retreat too far. They didn't even turn the first corner of the passage.

The angel in charge of the road closure didn't know if it was due to negligence. The air route was not completely blocked, but a small hole was opened!

Seeing an opportunity to take advantage of it, the vampires went berserk again and rushed forward desperately to attack the defense loopholes!

And the angels and celestial hunters are also good this time~

They no longer stare at a vampire to kill. Instead, they use various group attack methods to continuously deduct the vampire's life in large areas. At the same time, they also control the loophole very strictly. Only three or two vampire bats can be released every second.

The speed of flying.

Of course, it still looks amazing, that is, the speed at which the enemy kills vampires has been significantly reduced. And the vampires are constantly breaking through the blockade and rushing towards the enemy's "back array"!

Almost at the same time as they broke through the angel's defense line, the entire tunnel suddenly echoed with the violent sound of horse hooves!

The next moment, bright knights suddenly rushed out from more surrounding tunnels in an endless stream, directly using the secondary charge speed to knock away the vampire army~

Although it was impossible to achieve the ultimate charging effect in such a place, the vampire bat's own strength and physical attributes were too weak, and it still suffered an almost devastating attack from the Bright Knights!

In particular, the enemy attacked the side of the vampire army. Not only did they severely damage the attack target, but also injured and killed countless vampires. They also received no counterattack from the vampires. They made a huge profit in vain!

What's even more shameless about these light knights is that after they succeeded in attacking, they actually ignored the pursuit of the vampire bats who reacted around them, and turned over and began to retreat collectively!

More than a thousand bright knights suddenly emerged, divided into about twenty groups. Each group had a squadron of knights. When they rushed out, they spread out in a fan shape to attack the enemy. When retreating, they quickly merged into a line and evacuated along the way they came.

Come and go like the wind, with perfect discipline. Like the most well-trained knight!

And the heavy iron armor they wear also ensures their safety, which is enough to withstand the attacks of surrounding vampires. Even if they lose blood slightly quickly, they can quickly recover their blood through various self-healing methods, and they are not afraid of the pursuit of vampire bats.

"Chase! Kill all these arrogant knights! Let them know who owns the world here!"

A scream suddenly came from the vampire group, obviously the other hero was unhappy~

But just when he ordered his descendants to hunt down the retreating Knights of Light, suddenly another group of Knights of Light emerged from deeper, closer to their vampire stronghold!

The Bright Knight who just rushed out used a fan-shaped attack formation to wipe out all the enemies around the tunnel exit~

It’s just that this time these knights didn’t turn around and run~

on the contrary!

Before the vampires could react and fill the gap, the clear sound of horse hooves suddenly came from the tunnel again!

The next moment, another squadron of knights pounced on them, following the attack route of their teammates in front and clearing out a group of vampires again!

And in front of their attack route... is the stronghold of the vampires!
