What could 'the way life should be a novel' imply?

A young man with an extraordinary mind is off on an exciting adventure when he mysteriously wakes up in the body of a feeble slave-guy in a different, rich in quirks world. The main character, a selfish jerk, would use extreme means to achieve his goals. However, he never allows his base instincts to overrule his sense of decency. He always pays back both good and bad deeds. Will his (terrible/excellent) mentality help him make a fresh start? Will he get through misfortunes and hardships of the new world?

The way of a Demon Lord- since the beginning of time, countless demons dreamt of it but few dared to tread on it, and even fewer reached its end. But the rarest of them all were some special demons who were not allowed to step on it, because if they were to become a Demon Lord- even the other lords would have to bow their heads. Abhorred and hunted by all, they could not do anything but hide till their lifespans came to an end. But for the first time ever, one such demon chose to do otherwise. Follow Adrian Darkheart as he uses his special demonic power, superior intellect and innate brutality to walk the path of chaos and destruction and become the greatest Demon Lord ever.

English is not my first language so please take care of me and if you find mistakes in it tell me I fix it as soon as possible. Max Winchester died due to an "accident" while reading the novel after his death he meet God who allowed him to travel through and do whatever he think best but on condition to make Protagonist's life miserable. He also gives him the strongest system [Netori system] that help him steal Protagonists Woman, Chances, Luck, etc Why does God want to make that Protagonist's life miserable? And why [Netori system] given to the max let's find out. (English will get better after chapter 38.) I don't own a book cover, I find it online, If creator wants me to change it just message me, I will remove it.

When I died I didn't expect to wake up with dark beings of immeasurable power looming over me. I didn't expect to be given new life in a brand new world. Now, armed with a powerful system that makes me stronger after every fight, I might be the last thing standing between the multiverse and absolute annihilation. As I complete quests, defeat foes and become stronger, I still don't know if I'll be able to save this world, my old world and all the worlds in between. "And below... the MAW beckoned..."

"A Villainess should be strong," she thought as she vaporized an entire lake. The day Estelle Clareste was born, she already had the memories of Kirisaki Reina, a 21-year-old woman living in modern Japan. From a Villainous Duke's daughter, to the world's leader, and suddenly a Goddess?! Estelle's past, was it as simple as she first thought? Or was there something more lurking behind? Will she achieve her goals, or will she meet her downfall before that? -Photo not mine, I found it on Pinterest ^^-

Dropped. Don't read this. *** Various monsters came out from mysterious gates that appeared all over the world. Along with this incident, humans also gained power and were called hunters. Radmilo Laiv is a hunter with the power to control time. He spent his life serving the world government and becoming a hero. However, he was killed because his power was considered a threat to the government. It was a stroke of luck that Radmilo could return to the past because of his powers. In this life, he doesn’t want to be a hero anymore. Should he play the evil role and become a villain? *** The cover is mine, commissioned by @erminea_ on IG 暂停。
