Follow suit.

Yi An pulled another vulture, quickly stole it, and then obtained a third-grade blood crystal.

He only has the strength of a first-rank early stage spirit martial artist now.

Although the comprehensive strength is strong, the realm is not improved, and the spirit element in the body is not enough at all.

What he had to do now was to quickly reach the middle stage of the First Rank Spirit Martial Master.

In addition to stealing physique, he also doesn't let go of spirit.

His physique has reached the middle of the first grade, and his spirit is still lacking in shortcomings, and only when the two data are synchronized can he enter the middle of the first grade.

Fortunately, it's only the first wave of monster charges now, and they can't get up the wall in a short time, so they don't need to rush to kill yet!

"I'll pull the monster over, Xiao Hei, you can cripple it."

After killing three vultures in a row, Yi An took out a one-grade body Yuan Pill and took it, recovering the lost spirit yuan, and then facing the little black path in his arms.

Although Xiao Hei has not yet reached the strength of the third grade, its comprehensive strength is very strong, after all, it is a spirit beast!

"Meow~"

Blackie jumped on his shoulder and screamed.

"Whoosh~"

The vitality poured in, and the chains flew out, quickly wrapping around a vulture, which was pulled back by Yi An.

The vulture was bound by chains and landed on the city wall, Xiao Hei screamed sharply, jumped up violently, the cat's claws grabbed the vulture's neck fiercely, and the other three limbs stepped on the vulture's body, and the sharp claws pierced into its body, and the vitality damaged the vulture's internal organs.

Yi An hurriedly stepped forward and stole it, and after stealing, he killed the vulture with one palm.

With Xiao Hei's help, his pressure was greatly reduced, and he continued to pull monsters and kill monsters.

The others didn't know why Yi An did this, but they didn't dare to be distracted, and honestly took the arrows or filled the elixir to deal with the monsters that attacked the air.

It's already getting dark.

The lights above the city walls shone on, and everyone did not rest and continued to fight.

If the vitality is insufficient, the backup team will be on the line.

Take turns fighting.

But in the huge dense forest outside, the monsters seem to be infinite, and there are constantly monsters rushing out of it, and all of them are dying.

After an hour, Yi An was tired and out of breath.

During this time, he killed forty or fifty vultures.

Both physique and spirit reached 450 points, and both Yuanquan and Linggong expanded by one point and became a mid-rank spirit martial artist.

After becoming a mid-stage spirit martial artist, his physique and spirit reached 465 points, each increasing by 15 points.

"It's still the fastest improvement in strength in battle, let's see if we can reach the second-grade spirit martial artist today!"

Yi An took the next piece of third-grade blood crystal, replenished the vitality in his body, licked his lips excitedly, and the chain in his hand flew out again.

Trapping a vulture again, he proceeds to steal and then obtain the Blood Crystal.

"The monster has stormed the wall, melee preparation!"

At this time, a grandmaster at the city gate shouted.

"Ah......h

When the grandmaster's voice fell, Yi An saw that outside the city wall near the city gate, many green snakes, rats and poisonous frogs climbed up on the corpses under the city wall.

The students who were thrown into the monster pile were torn into blood foam by the monster in the blink of an eye.

Seeing this scene, Yi An's face turned pale, not only him, but even some of the students around him who saw it were also pale and their bodies trembled.

"Ah~"

At this moment, another terrible cry sounded, and a student was bitten off by a mouse without hurrying to dodge.

"Don't look at it, if you don't want to be like them, just be serious with Lao Tzu!"

Yi An yelled at a few pale freshmen behind him.

The old student has experienced the secret realm, his expression is very indifferent, and his emotions have not fluctuated much, probably used to seeing this scene.

As there were casualties, some of the students became depressed.

"Don't be timid because of small casualties, this is war, casualties are inevitable, we as warriors dare to fight without fear, we don't want monsters to kill into the city and slaughter our relatives, so we take up arms and kill these beasts, kill!"

As if feeling the oppression of the students, a general in the military department shouted.

"Kill!"

A group of military warriors and soldiers shouted in unison.

These military warriors, armed with sabers, slaughtered the monsters that climbed up, each fierce and abnormal.

The morale of the students seems to have returned a lot, and they all gritted their teeth and continued to kill monsters.

Yi An looked at the monsters that kept climbing up in the distance, and he glanced under the city wall in front of him again.

The city wall he was on was far from the city gate, but there were still many monsters below, and even the mountain of corpses had piled up to two-thirds of the city wall.

Damn, they can't be allowed to rush up, and once they do, I don't know how many people will die.

Yi An scolded secretly, jumped up violently, and landed on the city wall, "Give me cover!" ”

When Xiao Hei, Fang Yuhao, Xu Hai and Zhao Yang heard Yi An's words, they all moved closer to Yi An and helped Yi An clean up the monsters around him.

"Oh~"

A fireball came out of Yi An's hand, and the fireball was small, only the size of a pigeon's egg.

"Make Lao Tzu bigger!"

With a roar, he poured all the aura in his body into the fireball.

All of a sudden, the fireball became dozens of times larger, the size of a basketball.

He had been fighting with his vitality before, and if he hadn't used his aura, if he didn't use his aura, his aura would stay at 50%, half of his aura and half aura.

His current spiritual element value is 67%, that is, 50% is aura.

As the fireball grew larger, his spirit value was finally reduced to only 27%, and 40% of the aura in his body was drained.

Seeing the fireball in his hand, the faces of the surrounding students all showed shocked expressions.

Not far from them, it was Yanhua's students, and it was Sun Ji who fought with him in Yanhua who led the team.

Sun Ji was also shocked when he saw the fireball in Yi An's hand.

This kid turned out to be a spirit martial artist, if he had used spirit skills in the first place, I would have been defeated a long time ago!

It seems that he didn't want me to lose so ugly before he released the water, I'm not as good as him!

He clenched the broadsword in his hand and sighed secretly.

"It's all for Lao Tzu to die!"

Yi An shouted, and the fireball in his hand was thrown towards the bottom of the city wall.

"呲呲~"

The fireball fell on the mountain of corpses below the city wall, and instantly burst into flames, and all the corpses of monsters that were burned emitted a smell of meat, and after a few seconds, they were all burned to ashes.

The fireball released by the spirit master is not comparable to ordinary flames.

If you get it, you will burn it!

The monsters that had originally rushed forward all stopped when they saw the raging flames.

These low-level monsters are not intelligent, but they can sense the threat from the flames.

The city walls were full of corpses, and these monsters had hair except for the green snakes, and the flames had a tendency to burn the plains, and began to spread along the city walls.

As the flames spread, all the monsters on the corpse mountain were burned to death, and the monsters that rushed forward stopped one after another.

For a time, the pressure on the students on the city wall was greatly reduced.

"The corpses below are burned, the monsters can't come up for a short time, everyone defends against the air attack monsters!"

The aura consumption was too great, and Yi An, whose face was a little pale, commanded the students around him.

"Brothers, kill!"

Xu Hai held a vitality gun, poured vitality into it, and attacked a group of crows rushing in the air.

The other students also recovered from the shock and began to deal with the air raid monsters.

"Whew~"

Yi An jumped down from the city wall, breathed a sigh of relief, and hurriedly swallowed a spirit pill to restore the aura in his body.

He is a spirit martial artist, and he needs to use the Gathering Spirit Pill.

The twenty Gathering Spirit Pills in the system warehouse were all handed over to him by Fu Chen earlier.
