Time Travel at the Same Time: We Are All in Trouble

On the first day when Xiao Tiancai traveled across the heavens, he found himself being beaten at the same time. On the verge of death, he unlocked the All-Heaven Bathing Club - sharing all the inner power, chakra, devil fruit, and divine power of law. When new members join the club, they are first ranked by seniority. Twenty or so of them grab snacks and play games in the pool with their butts naked. They complain about the stupid plots in their respective worlds when they have nothing to do. When something happens, they collectively stack buffs and go back to reduce dimensionality to attack. Be a hero in the world of martial arts, catch gin in the world of Conan, help Naruto chase Sasuke, accompany Luffy to save Ace, beat the hypocrite Yue Buqun, beat the double standard Tang San, work all the way from kindergarten to the ancient Purple Cloud Palace. Others are vying for supremacy in the sky, and we are all in trouble, but we are all invincible. Stranger, Douluo, Coiling Dragon, Swallowing, Covering the Sky, Journey to the West~~~ and more worlds are open
