This Lord is Very Scientific - Chapter 822 - 754:

The Soaring Dragon Continent is a world of summons, you can only become strong if you become a summoner! Yue Yang, an average high school boy, was suddenly transported into this world. When he woke up, he was greeted with a lot of worried faces and found out that he had assumed another person’s identity. Turns out he’s the good-for-nothing third son of the Yue Family, who had just recently drowned himself because of a failed engagement. Unlike the third son of the Yue Family who was useless in summoning, Yue Yang succeeded in making a contract with a summoning grimoire on his first try, even when the other guy failed for the past fifteen years. Others would have a headache making contracts with beasts afterwards, but countless beasts tried to gain favour with Yue Yang instead, acting like a good kid before him.

'A self-centric Female Lead, lost-in-love Male Leads, and useless extras who will die. On top of it, this world will not be here for long because of that ancient threat. So, what should I do now?'What kind of world was a world of Female-Oriented Fantasy romance? One filled with tinted glass and roses? Life should have been easy here, right? Wrong! Layla had read this book before, and she knew what happened.“Those useless leads left this world in a shamble! I need to do something about it before it gets destroyed. If I am going to live here, I need to ensure this world stays alive long enough. Who has time for romance when the world will end soon?”Her goal was set, and her life was laid out. Layla was going to use whatever she could to secure her second life.Everyone was a useful piece from here on, and Layla used them well to achieve her end goal. This might be a world based on a fantasy romance, but she would ensure it would not repeat it's ending.______Note: It has a strong Female Protagonist as the MC. No romance, no harem, no yuri.

“I can’t accept this! I can’t! Even as a ghost, I’m going to spend eternity cursing that your relationship will shatter like glass! Break apart like a pair of mandarin ducks that fly away from each other!” With such a persisting obsession, it would be difficult for the vengeful departed spirit to move on.

Three thousand years ago, gods and Buddhas disappeared all over the sky, and the inheritance of practice was broken. It was not until the ancient civilization was destroyed that spiritual energy recovered. Ten thousand races took advantage of this to invade.

Five hundred years later, the human race gradually rose up and began to fight for control of the land of China, and counterattacked all races.

Three hundred years later, Fang Yi, the Lord of the Great Dao, slaughtered all clans, destroyed all the heavens, stepped out of the myriad realms, and fought against the Dao of Heaven.

In desperation, Fang Yi sacrificed blood to eight hundred small worlds, reversed time and space, and was reborn nineteen years old.

In this life, he wants to live a more relaxed life, perfect his Dao Xin, and conquer the Dao of Heaven again.
