My Multisystem In Isekai

But Calista, who was on the sidelines, understood that her team had just lost their best chance of defeating Rebecca. The girl had seriously managed to upgrade her level by relying on the potion midway between the fight. Not only that but she had also managed to absorb the potion completely which meant that the increase in the mana level of Rebecca was bound to be more than normal.

The tables had turned on Merion High School as their opponent had not only recovered her mana but had also managed to evolve during the match which would have definitely enhanced her fighting strength.

Calista was sure that the girl in the field had definitely become a C rank mage by taking the evolution potion which was not the very best thing for her team. Her strategy needed to be changed if they wanted to survive past this round. Considering the circumstances, she was not sure that her team could make it past that round and into the finals.

She attracted the attention of Nadia on the field and asked her to play defensive. Right now, they needed to make time for themselves. Her team needed to build up confidence since they had to fight a C rank mage now. The competition between the two teams no longer looked unfair since a C rank mage was now on the opposing side.

Rebecca was still lying on the ground in a dazed manner as she was still not able to understand what that magical energy from her womb had been that had helped her complete her evolution so easily.

The white bearded old man in the stands on the other hand was so excited that he was barely able to keep himself from jumping up and down on his place. He kept looking in her direction in order to attract her attention and when she finally looked at him with a confused look that said that she was still unaware whether her strength had improved or not, he gave her a thumbs up. He wanted to tell her so badly that she done well for their school, she had done something no one else could have done. She had turned the odds that had been against her from the beginning in her favour. Now they had a chance to go into the finals. He wanted Rebecca to do her best.

Rebecca felt that the shouts and excited roars of the old man were quite funny but her confidence that had died while fighting the trio had come back a little.

Rebecca stood up from the ground slowly. Her dust spattered clothes were in disarray so she started by dusting herself off and managed to do so in a dignified manner. It was then that she finally found the unending reservoir of mana inside her body. This was what an infinite battery must feel like because to her there was no end to the power that she was able to feel within her body. The jump from the D rank mage to a C rank mage came with a considerable power level increase. She was just feeling its exaggerated effect since she had newly advanced to C rank.

Unconsciously, a smug smile formed on her face as she felt her own power.

"I am indeed a genius."

She had finally found her prideful self once again by doing something that others kept telling her with their eyes was something inconceivable for them.

Rebecca had never thought that she would be in this kind of a situation ever. A crisis could only be averted at the very last moment because she was able to burst out with an immense power that she had managed to acquire mid fight just to defeat the opponent that had been too difficult for her before. This wasn't a normal situation at all.

The reason was that this was something that only happened to the protagonists of the stories that she had grown to like in her childhood. Whatever the reason may be, Rebecca finally felt that she wasn't an extra at least on this day. For today, or at least during this fight she truly was the protagonist. She had earned at least that much by going through so much pain.

She was curious to see the results of her transformation as she had now advanced a stage. She looked at her palm as she tried to transmute it into diamond just like before. The mana that mobilized inside her body was a tremendous amount compared to before but the result astonished her even more. The sparkling and glittery diamond skin had now changed to become charcoal black with a lustrous shine. The color of the diamond defense had changed to pitch black which was both crystalline and lustrous in looks and looked tougher than before as well. She found the change to be quite interesting.

At the same time she felt that the diamond skin had increased many folds in strength. She wanted to experiment with her newfound strength until she had gotten a hang of her true abilities. She didn't have to especially care about her mana since the amount of mana she had was probably more than all the mana combined of her opponent team members.

After she had evolved into C rank mage, she had far surpassed her peers in terms of the amount of mana she could hold at any given moment. Therefore, she could probably waste some of it practicing which might also help her acclimatize with her new body and her bursting strength.

The next thing to test was her lethal laser attack. Since her diamond transformation skill had changed a lot, she was expecting that the laser should have improved by several degrees as well.

She looked towards Nadia who had been attacking her nonstop and fired a laser at her. To her surprise, the laser had changed its color as well. It was the same color as the color of her improved diamond transformation skill. Not only had the color changed, the attribute of the skill had tilted towards destruction as well. It was something that was meant to pulverize everything in its path.

Nadia was almost unable to dodge in time. This was the first time she had encountered such a fast paced attack. In fact, this was the first time that Rebecca had used such an attack on her. Previously, Rebecca had been too exhausted to even think of launching a laser attack at her opponent.

Nadia was barely able to dodge when all her senses went on full alert and her brain started sending out response signals with lightning so as to save her from the calamity that was heading her way.

Even so, it had been a very close call and Nadia had barely thrown herself out of the way.

The laser was too fast to be seen by the naked eye. It could have taken any one by surprise let alone Nadia who had been busy being a bombardier.

Nadia for fear of being caught off guard once again, conjured a shield of mana around herself in order to block a similar sneak attack. Now that her opponent had the mana to retaliate as well, she too had to think of defensive measures to ensure she wouldn't lose instantly to her opponent.

Rebecca on the other hand felt as if she was traipsing on the clouds. The laser that she had difficulty firing off before was as easy to fire as the flick of her wrist.

​ She had a feeling of unprecedented control over the laser that she had just fired. Gears in her mind began turning as she continued to imagine what she could do with that increased control.

As a result, she decided to experiment some more as Nadia was no longer a threat to her after having lost most of her strength. She was the perfect guinea pig for her to test her new strength on. She forgot about the match for a while and played with the lasers.

She tried to use the newfound control over the lasers but found it slightly difficult at first. There was something that she had failed to grasp as if she had missed something important but was unable to remember what it was.

After firing two more lasers that were skilfully dodged by Nadia by getting out of their path she finally started to get the hang of it. She left a trace of her mana on each laser that she shot. The trace of mana acted as an antenna or a signal transmitter for her to exact control over the fired off laser. This was what she had been missing all this while. She wondered if the result would be as she had expected.

In fact, she hadn't been sure about it at all. She had gotten the idea from Kacie who had used the same trick to control her weapons. The difference between the two was that Kacie was like a puppeteer controlling her weapons with strings made of mana, while Rebecca was closer to what could be called a psychokinetic using mana as a transceiver at both ends.
