The death of Shi Fern provides Rollin with 4500 experience points.

In addition, the experience points contributed by several previous Zhongnin, his level was increased by one level again, reaching lv22 (433/6800)... He obtained 5 free attribute points and 1 skill point.

This allowed the free attribute points and skill points on his panel to reach 20 points and 5 points respectively.

······

After glanced at it, Rollin refocused on the battlefield.

At this time, the cave less than 3,000 square meters was covered with corpses.

They were either beheaded by sharp blades, pierced through the chest and abdomen by rock cones, or bombarded by detonation talismans and other ninjutsu. In short, their ways of death were different.

Most of them are blood slaves, almost two hundred.

And the ones who killed them were naturally the grass hidden secrets in the field.

However, while killing these blood slaves, they also paid a considerable price.

Not to mention the sacrificed Shifern and the other four Zhongnin, the consumption of chakra alone cannot be ignored.

Besides, they also used a lot of detonation talismans and ninja tools, which were all used a little less.

It is precisely because of this that they want to fight quickly.

Luo Lin naturally knew their thoughts, but he could not follow the other party's wishes. After all, protracted wars and attrition wars are his specialty.

Compared with the tireless undead, human energy is always limited, and ninjas are also humans. Long-term high-intensity battles will inevitably lead to mistakes.

And this is Rollin's opportunity.

In order to create such opportunities, he must constantly put pressure on the other party.

That's what he thought and did.

······

Leaving Zombie Bear and 50 zombies as guards, Rollin sent out the rest of the undead.

At this moment, there are 5 death claws, 18 vampires, 50 zombies, and nearly 300 blood slaves in the field.

There are only three Shangnin in the Caoyin Village, two special Shangnin, and eleven Zhongnin, with a total of sixteen people.

The comparison of troops between the two sides is almost 23:1.

Under Rollin's control, 50 zombies were scattered among the blood slaves and formed teams at a ratio of 1:6.

Then, he launched an uninterrupted attack on Cao Yin and others.

With the addition of these zombies, Cao Yin Anbu can no longer cut melons and vegetables like before.

Nothing else, unlike the single-digit double resistance of the Blood Slave, the double resistance of the Zombie is around 30 o'clock, almost three times that of ordinary people.

Adding 1,000 health points makes them not instantly killed when facing the attacks of Cao Yin An tribe.

In this way, other zombies and blood slaves can take the opportunity to attack.

It can be said that the combination of zombies and blood slaves is far from being as simple as one plus one equals two. This is a balance point of the "human sea tactic".

Without zombies, no matter how many blood slaves there are, they can only be beaten passively. With these 50 zombies, they can launch an effective counterattack.

Not only that, Rollin also arranged the 18 vampires to the outside of the battlefield and stared at the whole audience.

Unfortunately, after several rounds of skill display, their blood power is not much, and Rollin will not let them take action until the critical moment.

However, with the previous performances, even if these vampires did not take action and just stood there, they could still put a lot of pressure on the Hushin.

As for the five death claws, given their high intelligence, Rollin did not issue specific instructions, but just asked them to wait for an opportunity to launch a sneak attack.

Therefore, they still wander among blood slaves and zombies as before.

However, the people who had seen their cruel Cao Yin did not dare to be careless at all.

All these things made the Caoyin Annan tribe seem to be trapped in a quagmire and unable to move forward and retreat. The "beheading" operation has reached the verge of failure.

······

The snake grass kicked away the two blood slaves in front of them, swung the sword and slashed the zombies behind them, leaving a deep blood mark.

However, before he could take advantage of the victory, he had to take a step back and avoid the claws that were poking out from the side of another zombie and the attacks of several other blood slaves.

This scene not only happened to Snake Grass, but similar scenes also repeated in other Cao Ninjas.

You should know that most ninjas are brittle with high attack and low defense. As long as they are effective attacks, they can reduce their state.

As one goes up and the other goes down, flaws will inevitably appear.

By then, whether it is the Claw of Death, the Vampire, or the Rollin, they will take the opportunity to take the other party's life.

This is the characteristic of the human sea tactics.

······

Sure enough, within a while, a Kushin Chunin was accidentally scratched by a zombie while performing ninjutsu.

The poison of corpse entered his body, causing his condition to decline.

Then, several teams of zombies and blood slaves launched a fierce attack on him, not caring about the interference of others.

Just as he was exhausted from dealing with these attacks, a death claw found an opportunity and successfully attacked. This attack became the last straw that defeated the camel.

Then, after just counting breaths, several scars of varying degrees appeared on his body.

In the end, he was bitten by a zombie and died on the spot, contributing 660 experience points to Rollin.

Although eleven blood slaves and one zombie died during this period due to the attacks of the rest of the people, Rollin felt it was very cost-effective.

In other words, as long as the battle loss ratio does not reach 23:1, Rollin can accept it.

Because this means that the rest of the grass will endure more pressure next time.

Seeing this scene, Snake Grass stopped hesitating, shouted loudly, and said, "Cover me!"

Upon hearing this, several Cao Yin Anbu who were closer to him forced the blood slaves and zombies in front of him to retreat, leaned towards him, and protected him behind him.

With the cover of his companions, Snake Grass was freed up to quickly complete the seal and used a large-scale attack-type fire escape ninjutsu.

I saw three flames spewing out of his mouth, extending more than ten meters in a fan-shaped shape, covering the dense blood slaves and zombies in front of him.

Immediately, a strong burnt smell came, choking everyone unconsciously holding their breath.

And in Luo Lin's eyes, the health of nearly a hundred blood slaves was decreasing at a rate of 150 points per second.

In just less than two seconds, they turned into charred corpses.

As for the zombies, thanks to their nearly 30-point magic resistance, the health reduction rate is slightly slower, about 100 points per second.

Seeing this, Luo Lin mobilized zombies and blood slaves from other places to make up for the seats, and ordered the zombies in the flames to rush towards Snake Grass and others in suicide.

At the same time, he also began to mobilize his magic power and recite the spell of "Corpse Explosion".

A few seconds later, more than a dozen zombies covered in fire stepped over the burnt corpses on the ground, rushed out of the flames, and came to Snake Grass and others.

Faced with such zombies, they can only avoid them for a while.

However, without waiting for them to withdraw, a zombie in front suddenly fell to the ground.

Immediately afterwards, a dull explosion sounded, and the zombie turned into countless flesh and bones, covering a range of five meters.

The magic shock wave directly hurt the internal organs of several retreating Cao Ninja. However, the sputtering bones were blocked by them.

This blow is one of Rollin's trump cards.

The existence of the master-servant contract allows him to end the life of any zombie under his command at any time, and then cooperate with the "corpse explosion technique", which is a human bomb.

The effect is also great. Although it failed to kill any of the Kasumi, the unexpected attack still caused damage to them.
