Pyros and the Boulder

"What's with all the machinery coming through here?" asked Hu Tao one morning. "They're building a quarry at the Old Regisvine" said Bennett. "About time they added something new to that frostland of a mountain" added Xiangling. "Guys, I'm worried about something" Yoimiya said. "What are you worrying about?" said Hu Tao. "That boulder on top of the mountain, I feel like if they start working, the boulder might come down and cause you excessive amounts of damage" explained Yoimiya. "Don't sweat about it, Yoimiya, if that boulder falls, the workman would just smash it into tiny bits, it's not like it's gonna roll around the entirety of Teyvat or anything, so just try to ease your mind, luv" assured Hu Tao. "You may be right but there's something else I should mention" continued Yoimiya. "And what may that be?" the others asked. "In the night, sometimes I see a face just looking forwards, looking like it doesn't want to move its spot" Both Xiangling and Hu Tao just burst out laughing. "Oh ho ho, Yoimiya, you can't be serious, a boulder having a face, this isn't some silly TV show" said Xiangling. "Well, Yoimiya, you've certainly given us a good laugh, but like I said, there's nothing to worry about" Hu Tao finished. Yoimiya said nothing and just went to the Old Regisvine to inspect the boulder from a better view. "Yeah, that boulder's been there for years, it just kinda showed up one day and never left, we just never thought to bother it until now, interesting, huh" said Qiqi, but Yoimiya had her full focus on the boulder. Some machines were digging hard into the mountain side and then, "The boulder's moving!" shouted Yoimiya. "Don't be ridiculous, it will just fall and break into pieces" replied Qiqi. But she was wrong, the boulder descended and pounded the ground, it was rolling towards Yoimiya and Qiqi. "Run as fast as you can!" Qiqi said. The boulder was following the two with immense speed, they made it on Mondstadt where they'd thought they had lost it. "What happened" asked Bennett while being startled. "There's a boulder running loose, it's heading straight to here, everyone move to Liyue!" ordered Yoimiya. Everyone left just in time as the boulder arrived at Mondstadt. It smashed a few houses before heading to Liyue. "It's heading for my restaurant!" cries Xiangling. "Forget your restaurant, you rather be intact or be flattened like dough?!" asked Amber breathlessly. "You're right, let's keep going!" answered Xiangling. The boulder completely demolished Dori's house, it was nothing but shambles. Then the boulder was now in Sumeru, it was heading straight to Klee's hideout. "You know, Lisa, it's such a fine day, I can almost hearing the wind blowing" said Mona obliviously. "That's not the wind, that's a boulder heading for the hideout!" said Dori and Sayu. "Everyone out quickly!" warned Klee. Then finally the boulder stopped as it made contacted with the hideout, followed by a explosion. Luckily, the Dendros' hideout and themselves were not harmed. "What was that?!" exclaimed Lisa. "Can't we just go one day without our lives being in danger?!" complained Mona. Amber, Nahida and Qiqi inspected the damage firmly. "Looks like we need to build another hideout" sighed Nahida. "Well, the important thing is that everyone's okay, right Amber?" "This was an act purely setup by something out of our comprehension" Amber finished gravely. "We've should've left that boulder and it's habitat, alone"
