MTL - After the Eldest Sister-in-law Died Young, Dai Wen Remarried. - Chapter 520 opportunity

This is the 40,000th year of the Empire's dominance over the Galaxy. The glory of the Great Expedition has long been buried in the dust of history. Su Yu has transmigrated here, opening his eyes to the ruins of a planet in front of him, utterly bewildered.On this planet, there are war machines that stretch for thousands of kilometers, now broken to the extreme, alien beasts whose roars can shatter mountains and rivers, and radiation alien beasts whose mere movement causes further destruction to the surrounding environment—There is everything here, except hope.Whether willingly or not, Su Yu struggled to survive for three years and finally inevitably contracted radiation sickness, seemingly about to become one of the despairing.Until his Profession Panel, capable of infinite job transfers, finally activated.“Ding!”“Detected that the host has met the prerequisites; do you want to take the profession of [Mechanic]?”“Completing this job will allow you to gain profession experience through daily maintenance, recovery, and assembly of mechanical creations, leveling up the profession, and with each upgrade, you receive an enhancement amplification of your physical attributes...”Looking at the pile of broken gun parts in his repair room, an unprecedented light lit up in Su Yu's eyes!Years later, at the core of the Empire, at the highest point of the Terra world, Su Yu, the Mechanic from Ruins Star, Ghost Shadow Blade of Dead Silence Wilderness, Initiator of the Giant God Soldier Project's Restart, Governor of the Shattered Star Region, Master of Mechanical Ascension, Supreme Throne of the Forging World, looked at the torrent of steel gathering below and commanded with a wave of his hand![Our goal is to make the (second) (crossed out) Empire great again!]

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.

I came from hell, looking for redemption! –“Revelation”

Well, this is just a story. …
