In this world of wizard and magic, he embarks on a journey to explain magic with science. One day, a dragon takes him away.“This is not in line with aerodynamics? It does not satisfy the Kutta condition, Circulation Theory of Lift and Bernoulli's principle either? How can it fly? Is there a special power source in its body?” Richard could not help saying as he glances down at the huge dragon he was riding on. “Well, I need to research this.”“By the way, you said you kidnapped me to find a playmate for your daughter. That doesn't sound like a good reason, right?”“Roar!” the dragon hollers furiously and waves its wings, soaring into the sky.Will Richard be able to continue on his journey of exploration and unravel the mystery of the wizarding world?

In her previous life, Jiang Yan's mother was murdered by her stepfather under the guise of celebrating their wedding anniversary with a trip abroad, and Jiang Yan herself, holding a huge inheritance, was locked by him in the basement of a villa and had one of her hands mangled. As natural disasters became more frequent and the apocalypse descended, the stepfather's family, hiding in the villa waiting for the apocalypse to pass, ultimately set their sights on Jiang Yan...With the opening of her eyes, Jiang Yan was reborn three months before the apocalypse. After activating her portable Space and successfully taking her revenge, she, now in possession of a massive amount of funds, started a global shopping spree: yachts, helicopters, off-road RVs, weapons, amphibious boats, necessities for clothing, food, shelter, and transport; everything from five-star delicacies to tasty street food hidden in remote corners... she bought and hoarded them all, bringing everything into her Space!Seeing that there was only one month left, Jiang Yan began a cramming-style learning binge: shooting! Flying planes! Driving boats! Hand-to-hand combat! Agricultural Planting! She even learned how to operate an excavator from the Red Xiang Technical School!In July, a double typhoon that caused seawater backflow starting from Japan marked the beginning of the apocalypse. A super high temperature wave followed right after, sweeping across the globe, along with torrential rains, earthquakes, pest infestations, extreme cold, nuclear contamination, mutation of animals and plants... one natural calamity after another ensued!While others fought over a packet of instant noodles or half a bottle of water, Jiang Yan was leisurely planting vegetables, raising fish, sitting comfortably in her safe house with air conditioning on, and enjoying her hot pot meal~PS. This entire story is fictitious.

He—an enigmatic and cold-blooded soldier with a mysterious background.
She—a ruthless and bloodthirsty spy.

Xu Shiyan was reborn back to forty years ago, the second day of his wedding.

Shui Lingling’s daughter-in-law has just entered the house, and everything is off to the best start.

Farming, hunting, going to the mountains to dig a big ginseng, life in the 1970s was actually quite good.

I didn’t have much skill in my previous life, and I don’t have any grand wishes in this life. I just want to live a good life with my daughter-in-law and cultivate my daughter into a talent.

The eldest daughter likes to write, so let her take the Chinese department of a key university.

The second daughter likes to sing and dance, and the art school is good.

As for that bastard son, the prodigal son, he didn’t have a chance to stuff it back into his mother’s belly in his previous life, so he just wanted to be born in this life.

But why are some things different?
