MTL - Ninja World: Insect Princess From Konoha - Chapter 29 take an exam

Aaron, a wildlife biologist, became a military strategist right after a global war between nations began.He never wanted to participate in the war but he had to, because he wanted to continue his studies on endangered species the moment the war was over, but to his surprise, everyone in his unit were killed, including him, and the next thing he knew, Aaron woke up in the body of a young noble having a similar name to his.However, he also noticed he had awoken in a world different from Earth.In this world, demonic beasts ran rampart with only one thought in mind, causing them to feed on anyone they see, be it humans, elves or even magical beasts as well.During his first encounter with a magical beast, Aaron awakened a system which allowed him to bond with magical beasts and to obtain terrifying abilities from these bloodcurdling magical beasts, so he used his experience as a wildlife biologist to help make it easier for him to bond with these beasts.However, Aaron also noticed he could evolve these beasts if their loyalty towards him had reached a certain level, so he vowed in his heart to grow strong enough to protect those he cared about in this world with the hope of living a happy, peaceful life where he'll be able to focus fully on his passion as a wildlife biologist.

Cheated on by her fiancé weeks before their wedding, Sara, vowed to never love again. Men could not be trusted, especially with a woman's heart. She had made the mistake once, and that was more than enough for her. Never again would she make the same mistake to give her heart to another.But her resolve began to waver when she came across her new boss, Alexander Legend, a man whose reputation in his expertise and ruthlessness in business preceded him. Respected and feared by many, but to Sara, he was an annoying pest she wished she never met. Too persisted for her liking yet, she finds herself falling, slowly melting in his presence. Getting used to his stolen kisses and hugs and sometimes anticipating them.°°°°°Excerpts“You will fall for me, Sara. One day, I'll have your heart too,” Alex drawled. His voice had a seductive allure that had her heart racing. The fact that his hand was leisurely resting around her waist didn't help her either.“Try as much as you want to,” despite her body begging for his touch, Sara was determined to reject him today and any other day. She couldn't make the same mistake again. “You won't succeed in your seduction. NOT NOW. NOT EVER.”Alex smirked, kissed behind her ear and her body trembled, much to his satisfaction. That was all he needed to keep purising the stubborn woman in his arms right now. “We shall see, Miss Ambrose,” he cooed and then released her. He returned to his seat and asked in a professional tone. “What is my schedule for today?”

When he woke up, Lin You found that the world had changed drastically.

Monsters of all races roar and bombard wildly, field magic cards form a deep sea out of thin air, royal tombs, skyscrapers, and trap cards are infinitely possible.

Duellist colleges and universities all over the country are rising, and the miracle secret realm is full of dangers.

This is a world where all people chase cards, and the era of card duelists shines.
