This manga is one of my favorites, It's about a man named Senku manage to make incredible things from scratch in a stone world, and also it's comedic flavor, I highly recommend reading this manga, it will give you an exciting feeling when they just finished their inventions, and also the characters are good too. It has now 150+ plus chapters and it never ceases to amaze every arc in the story. Bunch of cool inventions great character development and has an amazing plot. Well I think you can somehow gain some scientific knowledge when reading the manga cuz the mc always talks about the contents in the table of elements and some scientific things (spoiler) right now i think they plan to go to the moon to defeat the enemy.
