MTL - Class Teacher System - Chapter 42 Heavenly

One day, the majority of humanity had a collective thought.

‘I wish the world would just collapse.’

And then, that wish came true.

This is a bizarre and mysterious world filled with various sinister cultivation methods. Once a person begins to cultivate, they will either undergo mild changes in appearance and temperament, descend into madness, or become a great elixir for evil beings to consume...Duan Yun, having transmigrated into this world, unexpectedly comes across a supreme elixir cultivation manual, the 'True Explanation of the Jade Sword.'To his surprise, he is a one-in-a-million cultivation genius who, unwittingly, transforms the manual into something extraordinary. Guided by the Jade Sword, he is able to pierce through everything.Later, as his mastery over various methods grows, Duan Yun, carrying the philosophy of 'the enlightened benefit the world,' never keeps secrets and spreads martial arts across the land.Who would have thought...“Duan the Demon misled me! He said this technique enhances yin and yang, but now I can only squat to pee, boo hoo...”“It was the Demon who taught me this 'Seven Parts Returning Qi'. Instead of blessing me, it brought disaster—I either get killed or step in dung. The fortune-teller said I've lost seventy percent of my luck.”“Don't trust a word of what Demon Duan says! The fairy of the Myriad Wonders Palace was supposed to ascend the whole palace to the heavens, but in one night, she was possessed and turned into a demoness, all due to that old demon Duan's handiwork!”...Duan Yun finds this incomprehensible. All he did was practice martial arts, spread techniques, and occasionally emulate the laws of nature, so how did he become notorious as a demon?This is slander!The same techniques cause no issues for me, so the problem lies with you all, not me!

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.
