The so-called "Blood Demon" is actually the re-evolved form of the Red Giant, the fifth form.

After observation, these Western Regions Zahu infected with "blood poison" have five stage forms:

The first stage of the "ordinary homeless" form: thinner than ordinary people, with an average height of less than 1.7 meters, agile movements, fast running, amazing strength, lazy behavior, no abnormal reaction except foraging for food without being stimulated, with an instinctive group nature, will follow the group action;

The second stage of the "Strengthened Soldier" form: Individuals who absorb the blood mist that overflows after the death of the same kind are strengthened, with an average height of about 2 meters, and the three-dimensional attributes of their physique are twice as strong as those of the "Wanderer" form, and they have strong self-healing power under the shroud of blood mist, and will actively wander to find targets to attack, but will not attack their own kind, and their skin is red due to the increase in body temperature;

The third stage of the "atavistic orc" form: the further evolved individual, the average height is about 2.2 meters, the three-dimensional attribute of the physique is several times stronger than the "enhanced soldier" form, the rapid evolution leads to the rapid growth of hair and minions, the skin is tough and defensive, the behavior is manic and aggressive, and will only follow the instinctive action like a beast;

The fourth stage of the "Crazy Blood Flame" form: the average height is about 2.5 meters, because the further increase in body temperature causes the hair of the whole body to fall out, and the whole body is shrouded in high-temperature blood mist, which can condense blood mist and turn into blood flame to enhance the destructive power, completely lose his mind, and even attack the same kind around him;

The fifth stage of the "Berserk Giant" form: the average height is about 3 meters, the skin is congested and red, the pores will spray high-temperature steam, forming a defensive layer that can resist the damage of battle qi, and the behavior is berserk and has a strong desire to destroy, and will actively hunt the same kind as food to supplement itself;

In the sixth stage of the "Blood Demon" form, the red giant obtains a large amount of nutrients and enters a state of rapid evolution after hunting its own kind, resulting in a rapid increase in size.

The height ranges from 3.5~5 meters, and the skin tension cannot withstand the swelling muscles and ruptures and peels off, exposing the subcutaneous blood-red muscles and white tendons, which looks like an enlarged version of the human specimen, but the body surface will flow plasma-like substances to protect the exposed muscles......

Does that sound like "Attack on Titan"?

Although the size is not so exaggerated, the problem is that they will absorb blood mist and grow rapidly, and they are always in a state of rapid evolution, and if they are allowed to evolve, the devil knows if they will grow the 60-meter-tall super giant in the anime.

Moreover, the thirty-meter-high city wall of Yumen Pass was no longer able to stop the attack of the Blood Demon.

They are able to jump three or five times their height out of thin air, and rely on their jump acceleration and their own body weight to break the rock surface of the wall with their claws and climb up with their strength.

If it weren't for the members of the Infinite Knight Order who were in charge of patrolling desperately preventing the other party from climbing the city wall, and persevering until Bai Yuqi, who got the news, rushed to kill the Blood Demon, once it invaded the city wall, I am afraid it would cause huge casualties.

But what's bad is that after the corpse of the blood demon killed by Bai Yuqi fell down the city wall, it caused a large number of "blood slaves" to divide the corpses and fight for food, which instead led to more blood demons!

The most troublesome thing about this kind of monster is that it will evolve, although it can kill them, but the dead blood slave will cause the same kind to evolve, and the more you kill, the faster you will evolve!

At the same time, the first Blood Demon climbed the city walls, which seemed to remind those blood slaves who would have only roared and wandered under the walls.

The large amount of flesh and blood gathered behind the city stimulated these manic monsters, and they began to imitate the behavior of the blood demon sprinting to climb the city wall, and launched an assault on the front line of Yumen Pass.

After being shot down by the Tang army defending the city again and again in the process of climbing, these blood slaves even learned the method of "stacking Arhats", scrambling to climb up with the bodies of the same kind, which looked like the scene in a movie "World War Z" that Bai Yuqi had seen in later generations.

The growth rate of the disciples under his command is still a little slower, and they have begun to be unable to keep up with the changes in the situation, although they can barely resist the attack of the blood demon, but it is difficult to kill the other party.

As a result, the blood demon who kept breaking through the defense line and climbing the city wall, forcing Bai Yuqi to be like a firefighter, kept running on the defense line of Yumen Pass.

Although after obtaining the [Spatial Power] status, Bai Yuqi has unlocked the ability to teleport in space, and can rely on [Flash] to quickly teleport along the Jade Gate Pass for support.

But it can't go on like this, no matter how strong he is, it is difficult to avoid such a long line of defense without making mistakes.

Bai Yuqi, who was on fire for a while, simply put a big move, and a [Cluster Summon] summoned the mountain guard of Zhongnan Mountain.

Because humanized animals are different from ordinary people after all, they are more in line with the image of "monsters" in the cognition of ordinary people.

In order to prevent the ignorant humanized animals from frightening ordinary people, or being used by humans with complex minds, leading to conflicts between the two races.

Therefore, unless necessary, Bai Yuqi has always restricted humanized animals to the range of Zhongnan Mountain in the Qinling Mountains, and did not allow them to leave the mountains without permission and appear in front of people.

But in the current situation, youkai or something is obviously nothing, no matter how scary it is, can it be more scary than the blood demon?

Whether it is a bear demon or a pig demon, as long as it can help, it is a good demon, and I believe that the Tang Dynasty soldiers and civilians who have been demonized by the world have tempered a big heart, so that they will not even be able to distinguish between right and wrong.

A large number of humanized animal races under the leadership of the brain beast Shi Wukong appeared on the walls of Yumen Pass in groups, and they with innate size and strength advantages were much easier to deal with than the ordinary Tang army.

Compared with humans whose strength has improved more slowly, simple-minded humanized animals have evolved much faster than humans when they stay in Zhongnan Mountain, a treasure land of immortals where the aura turns into fog, all day long.

As soon as it appeared, it forcibly suppressed the surging blood slaves, and suppressed them under the city walls...... The strong and strong humanized animals use heavy weapons, most of them are totem poles strengthened with [King Kong wood], big sticks and mallets or something, as long as the blood slave dares to show his head, according to the heavenly spirit cover is a mallet, simple and rough but effective.

However, the blood slaves who were blocked in their offensive may have been inspired by the sight of the Tang army defending the city, and there were actually tall blood demons and red giants, who picked up the smaller ones around them and used them as cannonballs, and smashed them on the city wall regardless of whether they died or not!

Although there was no accuracy, the tenacious blood slave did cause serious losses to the Tang army after being thrown onto the city wall, and even flew directly into the city, and the battle situation entered a white-hot state at once.

Bai Yuqi saw that the situation was out of control, so he simply didn't hide it, and a summon of the undead called the Regeneration Heroic Spirit Legion over, let's fight!
