MTL - Study Days at Hogwarts - Chapter 1275 good luck

In the vast and boundless continent Cangtu, there were ancient sects governing the Ten Old Domains, unworldly immortal clans beyond the Blue Sky, and primordial demon gods dominating the dark abyss that together created a great number of brilliant stories over the long course of the history.

The Earth of the future is united under a single government, but not all things are well. The shape of the playing field may be changed, but the powerful still rule the weak.And those who do not conform with the rest of society are exiled to another world. A world that not even the technology of the future managed to tame.It should have been humanity's New World but ended up as nothing more than a penal colony. A place where the exiled are sent to die.Motivated by revenge, Magnus sets out on a quest to bring his own justice to his enemies. For that purpose, he is willing to go further than most others.But then he learns that if he truly wishes to change things, he can only find his answers beyond the gate.Having lived most of her life as an exile, Astra is a woman of few interests aside from survival and climbing the ranks of her clan.To achieve those goals, she certainly won't be squeamish when a chance literally falls into her lap, or will she?———————————————————————————————I am trying to go with a survival/“no modern tech” setting in this one. People from a technologically advanced society are thrown into a world where they can't maintain their tech. They are forced to rely on what the world provides where they have to make do with the limited resources they have and what little of their old technology is still working. Their gene manipulation allows them to have something akin to superpowers, but that doesn't help much against the monsters of their new world. Not sure yet whether sufficiently advanced technology will be discovered later on to count as magic.It turns more political between the various clans later on.

Luo Feng was reborn back in his high school years. From the start, he acquired the Return On Investment System.

[Invest in this coffee shop and you will be able to open many branches in the future. It has an ROI of 100%.]

[Invest in Bitcoins and the price will skyrocket in the future. It has an ROI of 10,000%.]

[Invest in the cute girl who is the deskmate in class and she will become your wife in the future. It has an ROI of infinity.]

Luo Feng decisively chose to invest in his future wife.

…

Many years later, during a press conference, a reporter asked, “Mr. Luo, your White River Investment Company has surpassed Morgan Stanley and Goldman Sachs, becoming the most famous investment management company. In your opinion, what is the most successful investment you have made in your life?”

Luo Feng looked at his wife fondly as he replied, “Don’t ask me. I just live off my wife.”

Parents dead, clan exterminated, body burned, hands mutilated, inflicted with innumerable diseases, tossed into the dump, and even the magic ring with the ghostly grandpa in it has been sabotaged. A reasonable person would roll over and die. Tian isn't that reasonable. And as it happens, neither is Grandpa Jun. A very tough kid meets a very cunning old man. And together, they will shake the heavens. What to expect:-1 chapter a day M-F. Volume 1 is already complete.-2k words per chapter (aprox, some run long) with a longer first chapter.-No Harem-Earned power growth-An MC who isn't a goodie two shoes OR an edge-lord psychopath-A power system based on actual Daoism -Sects, giant monsters, natural treasures, flying swords, spells, talismans, secret arts, and a gentle sprinkling of young masters whose face need rearranging.
