I use Yugioh to battle the multiverse

I have a new story Detective Conan villain if anyone wants to try my new book

...

When the destroyer arrives, all the preparations are completed.

The giant metal spider (2500 atk 2500 def) quickly rushed to the town with the clear intention of squashing it halfway, its attention suddenly shifts to those crusaders using skill to lure it. The giant spider rushes to its target, which is the Crusaders. They run away, leading it to holes, where four spider legs sink into and get stuck.

"Now use it, Aqua." At Kazuma's command, she summons her wand, and a large amount of mana gathers around her, summoning five magic circles.

"Sacred Dispel" A giant white beam shot onto the giant spider's magic shield, but unlike in the original world, the spider knew her intention, so it used the stationary turrets to fire at the holes, freeing itself, and a giant turret appeared on its back, firing laserbeam back, clashing with the Aqua spell.(firing my laser cannon)

"I can't hold it much longer, Kazuma," Aqua said, trying her best to fight back but is slowly falling as the Destroyer's mana is infinite compared to her large mana reserve from her people's faith. It won't be enough, and if she can't break the shield, they will be doomed.

The other weaker magicians tried their best to help, but they couldn't do much. When Aqua is screaming for her life, Kazuma puts the pill in her mouth, making her swallow it. She almost thought that Kazuma's hatred hurt so much that he waited for the chance to throw poison at her. After a while, she feels her stats suddenly increase for a person already maxed out on stats. It is such a treasure that she can bypass the limit to increase it permanently in ways she has never heard of before, but now is not the time to worry about it as her output energy is now equal to the Destroyer.

Suddenly, Mana appears right beside her, using a technique similar to Aqua's, pushing back the beam. All the time, Mana is studying Aqua spells. Even if there are differences in the magic systems of this world, there is still some similarity, so Mana can create a weaker version of Aqua Dispel, helping her push back and destroy the magic shield.

Once the magic shield breaks, all the magic users suddenly feel the darkness surrounding them. This darkness is very comfortable and increases all the magic users' power. Ir even recovered their mana. Wiz the beautiful lich is the person who got the most from it. The feeling is almost like descending to cloud nine; it's very addicting and makes her almost forget about the destroyer, but luckily, Kazuma wakes her up. Of course, all of it came from Katsu's field card, Yami.

With such a magic boost, all of the magic users use their magic like crazy once the destroyer is weakened. Wiz and Megumin use their exploding magic together to send a giant exploding critical damage to the machine.

Once the machine falls, everyone cheers, but Kazuma knows that won't be the end, and the alert confirms his theory.

"Warning all spellcasters to flee, the machine has a magic-immune phase two and recovering ability." The cheers ended abruptly as the machine stood back up. The metal around the destroyed part recovers as many layers of magic shield appear. With its hard body and now immune destruction magic, it is almost unbeatable.

"I knew this mission wouldn't be easy. It's up to you next, Katsu and Gwen, "Kazuma sighs

Katsu has been summoning all his cards. Revival Jam has already turned into a sacrifice to summon Summoned skull, Kuriboh summons to help him bear damage in the case of injury, even if all his trap cards and spell cards are laid out. Mana had already returned to him to combine with him and Kaiser, Vorse Raider. Gwen, on the other hand, grows enormously into Way big.

At this time, all the monsters lured by the adventures are used as a distraction for the mobile fortress.
