Magic Card: Let Your Monster Attack the City, and You Will Destroy the World?

The will of the universe manifested, and billions of planets were forced to descend on the battlefield in the heavens and divided into two factions! Build a city to resist invasion - lead the monsters to capture the city! But no matter which side you are on, you must first become a card magician and summon magic cards to fight! Fengchen traveled through Blue Star and automatically joined the siege faction. He awakened the structure system and was able to manifest the unconstrained magic cards in his previous life! While the students were still thinking hard about the design of the graduation magic card, Feng Chen had already constructed the top magic card! "I asked you to do your final project, but I didn't ask you to create a true red-eyed black dragon!" "Aren't you a goblin? What the hell is Luo Lekainuo?!" "Are you crazy? You turned the wild boar into a six-star magic card? And the pig-headed emperor?" In Fengchen's hands, Ice Wolf Setsuna, Evil Dragon Spitz, Immortal Crazy Thunder Volibel, Battle Greymon, and Sirus, the Awakener of All Realms, appeared one by one! When the siege started, others had just occupied the target city, but Feng Chen had already led an army of magic cards to sweep through thousands of surrounding cities! Fengchen scratched his head: Sorry, I accidentally destroyed the world~ This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
