Use the Scriptures of Mountains and Seas to Build in the Wasteland

[Reading reminder]: Be careful, it doesn't look good, it's mainly a random writing A girl wakes up from the post-apocalyptic ruins with nothing but a pen and a book There are two gilt inscriptions on the pen: Magic Pen Open the first page of the book: Girl, do you want to become stronger? Summon your own mythical beast On the ruins, there are no living people but there are things that can be used The pen is made of meteorites and cannot be eaten, and the book is made of gold foil and cannot be eaten. When the hungry mountains and seas are hungry, they can only draw cakes to satisfy their hunger. Who knew that everything drawn with a pen could come true I was overjoyed and summoned a mythical beast, but instead I summoned a bunch of little animals that are useless except for being cute and edible. From now on, I not only have to feed myself in this desolate world, but I also have to feed these small animals that I can't get rid of. Especially that chubby guy who looks like a dragon but not like a dragon. He eats everything every day and still can't get enough. Fortunately, the magic pen is useful. It can not only draw cakes but also clothes and houses. As he became more and more proficient in controlling the magic pen, Shanhai drew a house to protect him from the wind and rain. The worthless mythical beasts cleared a clean land due to fighting Weeds grew on the heavily polluted land, opening up the road to farming in the mountains and seas Magic Pen: God entrusted us to you to save the world, not to build houses and farm fields all day long. Shanhai: What's wrong with farming? Only when you're full can you save the world. Later, the small house turned into a villa, and the small vegetable plot turned into a large farmland. Human beings scattered around the world struggling to survive gradually gathered around Shanhai Villa. The villa slowly turned into a village, and then slowly turned into a town. The polluted land was gradually cleaned up by the mythical beasts, and the mutated monsters became the toys of the mythical beasts. Shan Hai: Isn't this just saving the world? They say that people who work hard are the strongest. You don't understand. Magic pen:...... You win Purpose: Protecting the environment is everyone's responsibility
