The cave started to rumble and Kei had to dodge a pillar that was launched at him. Kei started to think 'What was this? Did the Boss monster escape its room again? Then he started to dodge multiple pillars. 'Is this what I think it is? Is the dungeon really forcefully evolving? But this rarely happens so why is happening now? I have to regroup with the group and ask Steph about it.' Kei after absorbing the Essences regrouped with the group.
"I'm sorry, I went a little ahead of you all. I just sorta entered into a trance and because of it I didn't even notice when I left you all behind so please forgive me." Steph accepts it and Kei asks him" Do you know what is happening here? The most I could guess and it is only a guess from me and it is that the dungeon is evolving but I don't think that would happen because it only happened only in a few cases and it involved an A or B-rank dungeon evolving so I don't a D-rank dungeon should evolve. " Steph pondered on what Kei told him and said, "As of now we don't what is happening in the dungeon so stay close to us and don't go out alone anywhere." Kei nods at that and Steph continues to say to everyone "Be careful guys, we might not know what is happening right now but I think we will soon till that time stay close and never let your guard down." The moment Steph stopped talking an Eclispewolf who was somehow bigger attacked the healer in the group and killed her by biting her head off.
Nobody could react to that attack because nobody could sense the Eclispewolf and they were shocked by it. Then it attacked the next person so fast that no one except Kei could react and he quickly blocked its attack with his blade. Kei takes out Yugen and puts Mana into it and the water starts to twirl around the katana. He dodges an attack from the Eclispewolf and performs a fake attack which the Eclispewolf falls for and moves into the position where Kei wanted it to be and he takes that opportunity. Kei tried to slice the Eclispwolf into multiple pieces but only cuts could make it through because somehow its hide toughened. 'What the hell is this? Usually, I could slice it into pieces even without the Mana but it wouldn't pierce through even though I put Mana in Yugen. This could only happen in one situation and it is when the monster ranks increase that means the dungeon also- 'Kei's thought was interrupted by the man he saved "Thank You for saving I would definitely repay you one d-" but before he could as Kei counterattacks the Eclispewolf which was planning to attack the man who had let his guard down. Kei shouts at the group "RUN! THESE ARE C-RANKED MONSTERS! YOU ALL CAN'T HANDLE IT>" After hearing this Steph took the lead and pointed the group toward the entrance of the dungeon.
Everyone formed a circle with their backs to each other and started to move. Steph stayed behind and shouted, "KEI COME!" Kei cut down the Eclispewolf and looked towards Steph but he was flung away by the Titatanstoned Golem which has evolved into Titanstoned Colossus. Steph rushed towards Kei and was about to take him and rush out of there but he noticed that Kei is absolutely fine. In the end moment Morphy without Kei's instructions covers his body in a protective cocoon but Steph didn't notice Morphy and neither he asked Kei how he was fine because they didn't have any time but he said "It is nice that you are fine, let's go if we stay here anymore then we will be in trouble." Kei sighs and places his hands on Steph's shoulder and says"If we go then all the monsters would be attracted to the entrance of the dungeon and everyone would die. So someone has to stay here to stop the monsters from coming there. I am stronger than you and you know that too so I will stay here. " Steph was hesitant to do that and was about to refute but Kei shouted "GO! NOW! " hearing this Steph started to retreat.
'Finally, he went away. Now I can focus on attacking rather than defending.' Kei thinks this and walks forward while cracking his neck. Zen, Captain, the monsters like some D-rank Eclispewolf, Titanstoned Golem, Dreadweavers and Luminari Weaveants came out and Kei makes a sword out of Morphy and he is holding a blade in another hand. "Let us get this thing started." and they all rushed towards the monsters. Kei already had his depleted after giving almost all of his Mana to the army he made out of Morphy but he still persisted through because of his Mana breathing technique and later he could still recover his Mana after killing the C-rank monsters. This was the reason why he didn't bring out the Mother of Dreadweavers.
Kei dodges an attack from Titanstoned Colossus and Zen blocks an attack from Eclispewolf which was coming towards Kei. Kei then puts Mana into his eyes to perceive the weak points of the Titanstoned Colossus and pierces it through it with his sword and creates a Mana imitation of the blade and slices its head off. He falls to the ground panting a lot as he almost entered the state of Mana exhaustion. 'Protect me, till I'm done collecting the Essences." but he noticed something and it was that some monsters which were destroyed remained destroyed and they were not regenerating as usually they would. But for now, he focused on collecting the Essences.
The first batch of the Essences that he collected caused him to hyperventilate and he almost fell unconscious because he hadn't expected or handle this much Mana to come at one go. He screamed as a Mana wave came out of his body and tossed all the monsters aside and the destroyed monsters of his army instantly regenerated. 'The Essence that C-rank monsters gives out is a lot different from the Essence that D-rank monsters give. It is more potent and refined than the Essences he has ever consumed.' Kei smiles maniacally and says "I WANT MORE OF THIS!! "
