[Monster killing upgrade + spiritual energy recovery + foreign enemy invasion + savior + no heroine + reverse time travel + low storage system + technological immortality]
My name is Hu Guang, I am a minor repairman in foundation building and very poor;
While he was picking up rags in the cave, the wall was suddenly broken by the flood;
When I came to the new world, the treasures here were packed by the pound, and I grabbed box after box;
Kill monsters and change into new clothes; exchange shotguns for cannons and I will become the king.
