MTL - The Record of Unusual Creatures - Chapter 1730 Constance

A 30-year-old NEET is reincarnated into the body of an otaku that choked to death on instant noodles. As he comes to grips with his new life, he realizes that this world is subtly different from Earth. The denizens of this world are far better looking, and this new world also possesses futuristic technology as well as mysterious Yin Yang masters!

I was reincarnated into another world, and I’ve brought the Horadric Cube from Diablo II with me.
Being a knight is cool and all, but being a wizard is pretty neat as well.
So, which one will it be?

Lu Lingxi died.

As a child born by his parents through precise genetic matching, for eighteen years of his life, he lived entirely for his brother, who had leukaemia. He was his brother’s shadow, a “medicine reserve bank” for his brother’s treatment needs.

Umbilical cord blood, stem cells, bone marrow… whenever his brother needed it, he would have no choice but to quietly lie on the operating table.

Until the last time, when his brother needed a kidney and he never came off the operating table.

When he opened his eyes again, Lu Lingxi became a teenager with the same name Lu Lingxi.

Freed from the shackles of his fate, he possesses the mysterious ability to communicate with plants.

Raising flowers, gardening and running a farm, Lu Lingxi begins a very different life!

Upon waking up from the dream, Josie traveled from the 21st century to Chicago in 1943, becoming a poor boy wandering the streets.

World War II? For Josie, who is still underage, it is too far away.

As an orphan, how he can survive in this age is the most important thing.

Fortunately, he has a plane trading system. In this era, being a master of time and space can make a good life if you think about it.

However, a few months later, Josie, whose life had just improved a little, looked at Captain America, who was singing and dancing with a group of girls on the stage of the war fundraising benefit performance, and fell silent.

It’s over, Barbie Q is over.

This is Marvel!
