In terms of the rules of online games, the soul fire is probably the experience value, absorbing a large amount of experience points, you can level up, which is manifested in the rapid growth of plants, and the skeleton soldiers are shining, the reason why they have not been upgraded may be that the experience points are not enough.

Anyway, Grell shoots a skeleton soldier, and the points are all fixed eighty, and if you solve the last one, it's just over three thousand, and a group of skeleton soldiers add up to less than a thousand, which is too little, but also.

So Greel, who was not interested in continuing to observe, immediately raised his Diend gun, aimed it at the glowing skeleton soldier below, pulled the trigger, and fired a beam of light, hitting the skeleton soldier's smooth head, and then exploded a violent spark, and the impact force generated sent the skeleton soldier flying three or four meters at once, falling into the lush grass and trees, and being covered by the vigorous growth of plants.

"What?" Greer was surprised, he could see clearly that the shot did not penetrate the skeleton's head, but exploded above the head, blowing the skeleton soldier away, indicating that the skeleton soldier's defense had increased, or that it had absorbed so much soul fire that its bones had become harder.

Otherwise, the shot just now would definitely easily penetrate its upper skull, and then when it penetrated the soul fire, it would be absorbed by the soul fire, and the scattered soul fire would disperse.

"Does this count as evolution?" Daisy was also amazed, this must have evolved, otherwise how could she block this shot.

"It should be—" Before Grell could finish speaking, he found that the skeleton soldier who had been blown away had risen from the lush gray-black grass, and his whole body was still bare, but at this moment there was no luster at all, only the soul fire burning in his skull, which radiated light from the seven orifices.

More significant changes are reflected in its body, between the chest cavity and pelvis, there are more than a dozen thumb-thick bones connecting it with the spine, supporting the upper body of the skeleton soldier, making its center of gravity much more stable, the original thin bone surface, now covered with a hard layer of the same color, wrapping the joint gap, but does not affect its activity, completely replacing the role of muscles.

"Looks like it's evolved." Grell is sure that the skeleton soldier has indeed evolved by absorbing so much soul fire, which is definitely the worst news, because it means that as long as there are enough soul fire, then the biological strength of the Heim Underworld can continue to increase.

Maybe there are skeleton soldiers with gold, silver and bronze, or death knights, bone dragons or something, and since there are skeleton soldiers, are there still ghosts, crypt lords, lichs, vampires or something, wait, vampires?

Grell suddenly thought of the vampires he had met at the Twist subway station before, he had forgotten about it, and now he suddenly remembered that the vampires should be considered dead or half-dead, and they couldn't be the natives of Midgard anyway.

So did the first vampire go out of the Heim Underworld? If so, it means that there is a secret passage between Heim Underworld and Midgard, or that there was a secret passage that can be found as long as you look for it.

But then again, those low-level vampires are obviously not once or twice when they wander the streets so unscrupulously, so it shows that the vampires hidden in human cities are definitely not one or two, and it is not a matter of one or two days.

"It seems that there are still many things that S.H.I.E.L.D. is hiding." Greer's first thought was Nick Fury and Coulson's talk about 'not letting people know what they weren't ready to know', and apparently the legendary vampire should be one of them.

While thinking about it, Greer pulled the trigger of the Diend gun again, and continued to attack the skeleton soldier below, wanting to see how many shots this seemingly evolved guy could take, and one shot after another hit the skeleton soldier's body, exploding one fierce spark after another.

'Boom! Rumble! Rumble! ’

An explosion echoed through the dark Heim Underworld, and the plants around the skeleton soldiers were shattered by the aftermath of the beam explosion, and a large amount of soul fire flew out of the shattered plants, or was absorbed by the fallen skeletons, or absorbed by other plants, or flew lightly into the air.

"It looks like my speculation has come true." Grell said in a low voice, these plants really have soul fire in their bodies, and once they are killed, they will drift away, in this way, a huge amount of soul fire can really raise an incomparably powerful guy.

High-altitude and long-range attacks, the skeleton soldiers on the ground have no temper, they can't get up at all when they fall to the ground, and each shot can blow up the bones on their bodies a little, and when they hit the nineteenth shot, the bones on their bodies are blown up into potholes, and the ground is full of broken bones.

The twentieth shot was fired, and the skeleton soldier exploded violently, turning into flying bones in the sky, and the highly condensed soul fire naturally left the shattered skeleton soldier and dispersed in all directions, like a dandelion blown away by the wind. Compared to the other skeletons, the soul fire of this last skeleton soldier spreads very slowly, most likely because there are neither skeleton soldiers nor plants, and the source of attraction has been lost.

"It's only two hundred." Grell lowered the diend gun in disappointment, allowing it to absorb at least seven times as much soul fire, but it turned out to be less than three times, which was too little.

Daisy, however, suddenly prided her ears and put her hand to her ear to amplify the voice she received, saying, "Shhhhhhhh ”

Grell held his breath and listened carefully, and after the loud roar of the explosion disappeared, the surroundings became silent again, so that even the small sounds could be heard clearly, and there was a fluttering of wings in the fog in front of him, getting louder and louder, obviously rapidly approaching here, and more than one.

"Something's flying towards us." Greer raised his left hand as he spoke, and the power of the Demon Emperor surged, quickly building a fire-based magic array on his wrist, and then the magic power gathered in Greel's palm, forming a fist-sized fireball, which was thrown out by Greel.

The bright light emitted by the blazing fireball illuminated the area it passed, and after thirty meters away from his hand, it was detonated by Grell with spiritual power, 'Boom! With a bang, the fireball exploded, and the light that burst out in an instant illuminated a large area, exposing a group of horses with rotting wings on both sides of their bodies,

The creatures of the underworld of Haim have been eroded by the breath of death since birth, and a little bit of death, they become zombies, decay into bone soldiers, decay into ghosts, and finally become death, absorbed by the plants of the underworld, become edible fruits for living beings, and then repeat
