Takarakuji de 40-oku Atattandakedo Isekai ni Ijuu Suru (manga)

Takarakuji de 40-oku Atattandakedo Isekai ni Ijuu Suru

 Kazura bought a lottery on a whim and won 4 billion yen.

To evade the hyenas that smelled the scent of his money, Kazura took refuge on an old residence that had been handed down from generation to generation.

When Kazura was investigating the place that would become his shelter, he stumbled on a certain room where it was possible to go into and back from another world.

The culture and technology level of that world was relatively low. The protagonist sometimes brought goods, sometimes brought technological knowledge.

At that world, he would find his true value as a person.

 SPOILERS

Our main character, Kazura, is one lucky son-of-a-bitch. He won 4 billion yen (roughly 51.5 million AUD) in a lottery and then moves into the mountains. He then finds a convenient portal to another world in his hallway and visits this new world and decides to help the villagers of it (he can also move back and forth through the portal). One villager in particular, Valetta, takes an interest in Kazura after he heals her father and other villagers with modern medicine (a vitamin-D supplement). Calling it now, they gon smash. He helps the village more by building water irrigation, and  teaches them to use fertiliser for their crops. Later Kazura bumps into Liese (daughter of the lord overseeing the village), an obvious rival for his affection. Valetta helps Kazura whenever she can and so begins their bonding. Things happen and Kazura gets arrested by the army, then released when they all realise he's a "god from another world". Kazura then goes to met the lord to help him with the kingdom and their food problems, and bumps into Liese again who seems to have fallen for him. Oh and one of the maids looks like she's starting to exhibit feelings for him too...BLAH BLAH BLAH, now all the food that Kazura has brought from Japan and fed to the villagers has made them super strong. and Kazura continues to improve the other world with knowledge and items from his. What could possibly go wrong?...
