Looking at the stone pestle and mud in front of him, Olga opened his hand.

    Because it is the magic of blood awakening, it does not need to sing spells or any preparation. A blood red fireball with a diameter of about 15 cm and releasing high temperature is generated in an instant, floating between his palms and illuminating everything in the cave.

    Whew!

    With his thought, the fireball flew out automatically and hit the obstacle covering the hole.

    Boom!!

    Like a bomb explosion, the sound echoed in the cave, and the blood red flame splashed everywhere.

    When Olga removed his magic and manipulated the flame to go out, he saw a big hole about three or four meters deep. According to Olga''s memory when he blocked the hole, another shot should break through all obstacles and penetrate the channel.

    So he gathered a fireball. The size and temperature were almost the same as before, but now he didn''t use fireball, but compressed the blood inflammation violence into a ball by virtue of spiritual force.

    Boom!!

    There was another explosion. When the fire went out, Olga began to observe the results of this round.

    The depth is about two meters. There are still some obstacles, but there are not many!

    However, he did not rush to start, but estimated the power and consumption of using fireball and not using fireball to directly compress the blood inflammation into a ball.

    The power of not using fireball is about half less than that of using fireball, but the consumption is about four times greater, that is, nearly eight times the gap.

    Next, he found a place to experiment with other spells and newly acquired talents, so he had a rough idea of his current strength.

    Sitting on a messy ground, after recovering the magic and physical strength consumed by the experiment, he licked his lips, stood up with a smile and walked to other parts of the forest.

    The next step is the second step to explore where you belong in the food chain of the howling forest

    ---------------

    The demon, who looks like a werewolf with a shell, feels that his life is being absorbed. His unwillingness makes him lift up his strength and try to make a final struggle.

    But how could Olga, who was aware of his intention, do what he wanted.

    With a faint hiss.

    Olgana had pierced his chest and stirred the tail of his body with great force with the high temperature of blood inflammation. He directly cooked its internal organs from the inside and shook them.

    Kill him instantly!

    The opponent''s rank is [little devil], which is stronger than the previous ape devil.

    However, unlike before, Olga''s strength has undergone a qualitative transformation. The opponent who had to fight to decide the outcome has no combat value!

    From beginning to end, Olga''s hands were useless. An instant blood spell [soul Impact] made his spirit hurt and fell into a trance. After that, his tail directly pierced through his chest, absorbed his vitality, and forced him to be weak. He could only be hung by Olga like dried meat.

    He tore off one arm of the corpse. Olga''s mouth, which was about the same proportion as that of normal humans, was directly split close to his ears, and a row of sharp teeth appeared. Then he took a hard bite at the food in his hand and tore off a large piece of meat.

    In this way, he took snacks, ate while walking, and wandered to other places

    The body hanging on the tail has been sucked into a mummy and thrown into the grass to feed flowers. After all, whether you are a devil or a human, you should take care of the environment!

    After leaving the cave, he had been wandering for a while. On the way, he met more than ten [little demons], seven or eight [young demons], and hundreds of demonized creatures produced in the howling forest.

    The ancestors of those demonized creatures, different from demons, are mostly from other planes, and finally stay here for various reasons.

    Their offspring absorb the magic in the bottomless abyss, drink the water of the abyss, eat the plants and animals of the abyss, and experience the pollution of the abyss. No matter what their original character is, they will become bloodthirsty and evil.

    The demonized creatures in the howling forest have high and low strength. The strongest should also be the [lower demon] level, and the weakest is a little weaker than the [young demon]. However, most of them have a common feature, that is, they have good fecundity, otherwise they would have been killed by endless demons!

    While Olga wandered in the howling forest for a long time. No matter demons, demonized creatures or even demonized plants, he did not encounter any one who reached the level of [lower demon].

    His plan to compete with the [lower devil] failed.

    Calmly across the stone pestle, the tail behind him quickly stabbed out, ignoring the other party''s simulated environment and optical stealth ability. He hit the key with great accuracy, stabbed directly from its brain, and stabbed the demonized creatures hidden in the stone pestle.

    For Olga, who has the ability of energy vision, the ability of invisibility is meaningless unless it exceeds his observation range and is immune to the additional effects of energy vision. It is not as real as the most basic fireball technique. At least he can watch fireworks.

    [+ 77 evolution point]

    He raised his head and looked at the dark sky. Olga frowned and thought of some discontent.

    "The efficiency is too slow!"

    Compared with the river bank, the demons all over the mountains fight face to face one by one. They only need to kill all the creatures that come into sight.

    Release the purest killing violence.

    The howling forest is more like a huge hunting ground. The dangers here come from places invisible to the naked eye.

    In the sky, trees, ground, grass and underground, as long as you want, there are hidden hunters everywhere. They gather their breath and hide in the dark, ready to deliver a fatal blow at any time. If you step on the mud casually, there may be several poisonous insects that can spray poison and corrode bones. Even a flower may release toxin to poison its prey, and then stretch out its tentacles to kill it.

    It can be said that the characteristics of the two are completely different. One is training the positive fighting ability of the devil, and the other is honing the malevolence in the devil''s heart and training it as a mature hunter who can face various complex environments and kill prey under various conditions.

    In terms of practical effect, this is a step-by-step way, which is conducive to the growth of demons. Without any mistakes, it can make them more comfortable in external aggression and killing each other.

    But for Olga, there are some small problems. For him who can grow only by continuous fighting and can make up for his defects as long as he has a point of evolution, these guys in the howling forest are hiding and fighting each other, just like guerrillas.

    It''s inconvenient to find!

    After looking for a long time, he couldn''t find many prey. He couldn''t kill as happily as the river bank. He could only play hide and seek slowly, which greatly prolonged his growth time.

    Olga also thought about whether to set off a forest fire and have a grand jungle barbecue, but finally gave up the plan after some attempt.

    Although his blood inflammation can burn the surrounding plants, those plants are all demonized plants. They have their own magic and can resist its burning to a certain extent. It can burn naturally when Olga continues to input magic, but once the magic stops supplying, it will be extinguished in a short time. There is no way to expand into a forest fire in the way of plant to plant.

    Moreover, there is another problem that even if those demons are burned, Olga needs to find their souls one by one. This is undoubtedly bullshit. When he arrives, those souls may not have been cheaper to others.

    This also exposed one of his shortcomings. He didn''t have any ability to collect souls remotely and on a large scale. Although he could burn those souls and make them silent forever, he didn''t have the ability to harvest them in space. At most, he bound them one by one by magic and his own soul power.

    According to his harvest in inheritance and memory, conventional demons must at least have the strength of [lower demons] to harvest souls from a long distance, and the other party can''t be too strong, otherwise they can''t stop, and they will encounter strong resistance.

    As for how to harvest the soul of the strong, the devil generally has three methods: 1. Kill him alive and catch him directly; 2. Lure him to sign a contract and harvest directly with the power of the contract; 3. Find a way to pollute the other party with his own power. When he becomes his own puppet, he naturally has the ability to harvest.

    At present, Olga has two choices and two development routes in front of him.

    One is that when someone in the outside world wants to summon abyss creatures, he takes the initiative to respond with the power of abyss contract, and then shuttles to the other world with the power of abyss, trying to beat the autumn wind before being expelled.

    The biggest problem with this option is that the devil knows who is calling him opposite and what the actual situation is opposite.

    It would be so fucking embarrassing to be bound into the magic array and see several mages laughing at themselves with research tools!

    Every day, there are a large number of demons who make a lot of money by calling from the outside world. There are also a large number of demons who suffer from fishing and law enforcement and become cherished raw materials of bottomless abyss specialties!!

    It''s a technical job that depends on luck. If you''re not sure, Olga didn''t want to try!

    The other is to mix in the howling forest step by step. Although the efficiency is a little slow, there are gains at least. Moreover, no matter how strong the opponent is, the upper limit of strength will be the level of [lower devil]. Olga feels that he can run away even if he can''t fight. As long as he is not blocked and beaten by a large group of demons, there should be no fatal danger.

    After three seconds of reflection and choice, Olga made a brave choice.

    It''s better to fool around in the howling abyss first. It''s not good to walk too fast and be killed!

    Although the devil''s nature makes him eager to kill, wantonly destroy and wantonly destroy in other aspects, the memory of being a human in the previous life also tells him that he will not suffer if he has nothing to do.
