With the help of the fog the old man were able to kill the weaker fallens but it came with a huge energy expenditure


    At this time one of the early-stage Knights discovered where the old man is, it waved its hand and produced two crescent shape energy attack that wished to cut the old man in half


    "[Copy Magic: Velocity Manipulation!]" The scientist poured a lot of his energy on this spell, although he have other spells to block this attack but most of it have a flashy effects


    For example, he can make a barrier made from fire, water, earth etc. However, doing so will make his location known to the other fallens


    The arcs of light stopped in mid-air


    "Ha!!" With a shout the scientist controlled it and it flew back towards the fallen with a faster speed than before


    The fallen was taken aback as it didn''t expect that its own attack would be deflected back to him


    The fallen flew higher to evade but the scientist won''t let that happen, as he let go of his control on the velocity spell he activated another spell


    "[Copy Magic: Wind Lock!]" A thin layer of winds covered the fallen''s body, the wind locked down the unfortunate fallen on its own place and the crescent shape energy managed to successfully behead it


    Wind his mind and tactic the old man killed a fallen with the same cultivation base as him with just a few spells!


    His intelligence was not only in research but also in a battlefield!


    "[Copy Magic: Fog Wolves!]" Another group of wolves were created using the fog in the environment, as usual it went to the weaker fallens and sneaked attack on them


    With this strategy the old man successfully killed all the Warrior Flying Fallens but just like Sun this made his energy reserves to be less than half of his full capacity after all maintaining this sea of fog also consumed a bit of his energy every second. There were still almost ten Knight Rank Fallens remaining and he didn''t know how he can kill all of those


    Sun stared at the four remaining mid-stage Knight Fallens who also looked back and howl


    The two muscular fallens charged towards him while the other two fallens used their long range attacks


    Two fist were flying towards him while two crescent shape energy and a cloud of gray fog shot towards him


    More of Sun''s envy energy came out from him body and his aura intensifies, his hair were being blown by the intense winds and this just add up to his demonic look


    Using the envy energy as a fuel to strengthen his physical attributes, he used his Lance to easily destroy the long range attacks of the fallens


    The two muscular fallens on the other hand managed to punch Sun on his body


    Sun forcefully bear the attacks with using the envy energy covering his body but it still made him to cough out some blood


    "[Hell Flame Magic: Blazing Stamp!]"


    Sun''s hell flames covered his right foot, this time the flames were even denser than before. Clearly, the amount of energy used was higher than the previous attacks and will deal more damage


    Sun did an uppercut kick, the fallen''s head was almost beheaded


    Without resting for even a second, Sun''s Lance that just blocked the long range attacks went to pierced the fallen''s head


    The lance came out from on the backside of the fallen


    Sun withdrew his lance and pulled some distance as the other fallens already launched another round of attacks


    "[Hell Flame Magic: Hell Flame Barrier!]" The familiar dancing black flames once again grew in size and become a flaming barrier that blocked the fallens'' assaults


    This was Sun''s strategy, he can kill a few of these fallens without sustaining much damage but it come with the cost of high energy expenditure and he does not have enough energy to kill all of his enemies


    Trading a kill for some injury was his strategy, after all the envy energy around his body passively gave him some protection


    "[Copy Magic: Magic Enhancer!]" A large amount of energy was absorbed by the old man''s grimoire and it shown with a bright light. This light revealed his location to the fallen''s inside the sea of fog. This spell will make the user''s next attack to be more powerful than normal


    "[Copy Magic: Mist Poison!]" A few cloud of fogs flowed inside all of the Fallen''s body, this was the old man''s gambleThis tale has been unlawfully obtained from Royal Road. If you discover it on Amazon, kindly report it.


    He only left some energy to maitain himself on the sky and the sea of fog


    When the fog entered all the fallen''s mouth, nose and ears it went towards their brain


    As if the fallens didn''t felt anything they all charge towards the old man


    The old man made the fog much thicker than before and used a spell to let the wind carry him out from sea of fog immediately


    The old man landed on the rooftop on one of the buildings in this city


    He closed his eyes and willed the fog inside the fallens to put everything into this last one attack which can be considered a gamble


    If he succeeded then all of these early-stage Knights will die, leaving only the mid-stage fallens to Sun


    However if they don''t succeed then Sun will face another group of fallens and their death was already almost certain


    The fogs slammed towards the fallen''s brain, surprisingly it met with no resistance and the fog destroyed the fallen''s brain easily


    Even the old man was shocked, if he do this to human supernaturals the humans won''t just let these fog kill them but instead use the energy inside them to destroy the fogs


    Surprisingly the fallens just let themselves be killed and the old man just credited it towards the fallens'' intelligence


    The old man looked towards Sun''s direction and looked at him with worry


    Surprisingly, the fallens changed their strategy. Instead of before where they let the muscular fallen to attack him in a close range now it only stood guard towards the two remaining long range attackers


    Although he can evade these attacks but flying also used some of his energy and this will just exhaust him further


    Sun gritted his teeth and flew towards the three fallens protecting each other


    Doing this will give him a chance to kill but it will also endager his life. What he was doing was the same as someone throwing a ball towards you but instead of evading you run towards the source closer, this will lessen your chance of evading


    An arc of gray light passed Sun''s body and it cut some of his hair, if he didn''t evade in time he will face some serious consequences


    As he come closer towards the fallens the frequency of attack become higher and some of these attacks barely missed him and landed a few centimeters on his body


    Thankfully, he have his envy energy protecting him


    The old man watched this nervously and looked at the arc of lights and fog that passed Sun''s body. He felt nervous as if something was not right


    When Sun was just a few meters away from the fallens instead of shooting out long range attacks again. The two long range attacker fallens waved their hands towards their own body


    Sun was confused by this but he brandished his Lance and thrust it towards the muscular fallen


    However, the old man''s face was full of terror


    "NO!! DODGE!!" He shouted but it was too late


    All the crescent shape gray light and gray fog didn''t disappeared when it missed and passed Sun''s body


    The previous attacks flew back and landed on Sun''s back


    The more than ten attacks heavily injured Sun''s body, if not for the envy energy covering his whole body he was dead for sure


    Still, blood flowed out from the injuries on his back and blood also continued to leak out from his mouth without a stop


    The old man''s grimoire once again hovered in front of him, unlike before where it shone with a single colored light now the light from the grimoire become a messy variety of light


    About a hundred light covered it, some are fire red while some are blood red. Even just the color red has a various type of it. It was as if all the colors represented something and that was the actually the case!


    The old man''s grimoire has a hundred page and he can use it to copy a hundred magic spells. The hundred light each represented a spell


    The old man used the remaining energy inside him to let the wind in the surrounding carry him towards Sun''s location


    Another group of winds covered Sun''s body and carry him to be far from the fallen


    At this time all of energy inside the old man was fully used up however, instead of being weak his aura rose and made the winds tremble


    "[Ultimate Magic: Myriad of Spells!!]" The old man''s life force were used as a fuel


    About a hundred circle of energy ball were created around them. These balls of energy quickly changed into a variety of spell with different magic attributes. These magics were not your usual magic, their size quickly enlarged and the energy on it become much denser


    Some of the spells flew and landed on Sun''s body and quickly cured his body. The remaining spells aimed towards the three fallens


    The muscular fallen made a gray barrier to cover them while the other two shot out another group of their attacks to destroy some of the spells coming to them


    However, with almost a hundred powerful spells attacking them it was more than enough to reduced them into just a pile of flesh


    The muscular fallen''s barrier was not even able to withstand even just a full second as it was immediately destroyed


    Sun''s body fully recovered and he looked towards the old man


    The light around the scientist''s grimoire vanished and the small amount of lifeforce inside him were also slowly vanishing


    Without the spell supporting him the old man started falling from the sky but Sun caught him


    The old man''s vision become blurry as his life force were already on the brink of exhaustion


    He looked at Sun''s face and it was as if he saw a familiar child on Sun''s silhouette


    "C-call me cough! G-grandpa D-derry"


    Sun''s eyes moistened, this was the first time he heard the old man''s name


    Stopping the tears from flowing out from his eyes, he cleared his throat so that he will not choke


    "G-grandpa Derry"


    The old man smiled lovingly "t-take care of yourself, o-okay?"


    "N-no! I won''t let you die!" Sun was not able to stop the tears from falling and he become indenial on the things happening to him


    Some supernaturals can do some simple healing on other people by using their energy to let the injured man''s cell to absorb and use, although it was not actually healing but just giving energy to the body to heal it. Sun wants to do that unfortunately, his energy was destructive in nature and will just burn on the old man''s body


    "No! You can''t die!" Tears continuously flowed out from his eyes, this old man was the first one to treat him with kindness and even sacrificed himself to save him. How can he let this old man die?


    "Anything! Is there anything I can use here?!"


    Sun''s mind furiously worked thinking of any possible solutions


    However he doesn''t have a healing skill and his raw energy was destructive


    Sun though of his envy energy, aside from boosting his power and making other people to feel a lot of envy its nature was not destructive like his normal energy


    Sun poured out all of his envy energy to the dying old man on his arm


    "Please work! Please work!" Sun didn''t believe in God but now he prayed that if there is really a God he begged it to help him


    Although the old man has healing spells but those will only work on wounds and not the depletion of life force that is why he only used the healing spells on Sun


    As Sun was just focus on pouring his envy energy towards the old man he didn''t know that when the energy entered the scientist''s body it also entered his ''sea of consciousness'' and was absorbed by his soul
