I was called to the capital due to some being wrecking havoc interrupting my experimentation in creating a human chimera that could camouflage among the people but of course the king had to interrupt my experimentation so I flew over and saw all seven heroes gathered and was confused usually this was only for World level threats which only happen maybe once in an eon. The king got up from the throne and said "Have you heard about the Blood Grove that newly formed if not a newly formed blood grove is supposed to be C-rank this one is A-rank at least and it has a master that tortured a dragon we know this due to the master of the blood groves scorn of this B-rank adventurer."
When they brought him out I gasped his wounds covered his body which was slowly getting eaten away by what looked like regular blood But I immediately knew it was Corrupted flesh eater Tree Sap which can only be formed by the most powerful blood grove so I used my magic to remove it and got out one of the empty bottles I had on me and put it inside but it resisted and started to try to eat my mana which surprised me enough that I almost didn't pull it off him.
The king looked at me and said "Yes we have found that the Corrupted Tree Sap also eats mana."
The others looked at me surprised that I could remove the Corrupted Tree Sap that eats mana which requires significant concentration but I did it with minimal concentration.
The king then said "Tell them what happened." He explains what happened to his team and how they were mascaraed by the core but spared due to the master wanting the king to be prepared so he could crush his hopes it seemed.
I then felt a huge mass of mana approaching but it was too fast and I felt a faint dragons mana and yelled "IT IS COMMING THE MASTER OF THAT FOREST PREPARE." my heart started to beat in fear I never had felt such an abundant mass of mana it was about twice mine in size and density meaning he had about 4x times the strength in Mana usage as me which scared me.
Luckily everyone listened to me except the king whom the ball of mana crashed through and I felt like I was a rabbit facing a dragon due to the aura he emitted. I saw a young figure covered in small Blood Borne tattoos which depicted his life and saw his despair and anger was due to no one trying to save his family so I sent out a message to the other universes about him and got a response from a god saying "We have been watching but we may not interfere and yes he has the power of a demi god currently and he is only at 2/10 of his power."
At that I almost collapsed but when I came back to reality he had stood up and was laughing and the paladin was gone due to a mana attack I think. I cast Greater Golem Formation of Diamond He waved his hand and cast Greater Blood Golem three times without using casting circles meaning he was innately a Blood Mage.
He dashed towards Cumort a great friend of mine and I knew his attack wouldn't be light so I Cast A rebound shield but it broke and the fist that hit my friend was knocked into the wall and I coughed out blood due to the rebound force that was transmitted to me by the spell which almost killed me and that was only about 40% of the attack. I looked over at Cumort and his wounds were repairing.
Tur^Ban Ran at him with his great war axe and swing it with all his strength he simply grabbed the blade and said "Nice materials Worthy to pierce my skin unfortunately I can not say the same for the owner." and then punched him causing him to fly back into the wall a spray of blood coming out his mouth and I heard him Use a Death curse Shaleanortan which causes the one cursed to lose all their strength for the rest of the day and then he collapsed dead.
Gasin ran at the thing Its not even human with this power there is no way that the tattoos are accurate in saying this thing was once human and became this way due to Rage. He managed to hit it with his blade but the blade shattered and not even a scratch was on him he simply grabbed Gasin's throat and started to choke him. He then looked over at Hammourn and said "I shall spare you due to the fact that you are not one who ignores those in need then he waved his hand and teleported Hammourn somewhere."
I started to regret all the things I did to the poor but I cast the spell death rattle sacrificing myself and hoping to save the world which had my family in it so I must save them even at the cost of my life I then felt a blood golem hand rip off my arm but I just kept casting this spell as my limbs were ripped off.
