Mdzs junior in the past

The air in the Gusu Lan library was thick with the scent of aged paper and ink, a stark contrast to the boisterous energy of the juniors. Wei Wuxian, ever the unconventional teacher, gestured animatedly as he explained the intricacies of his latest talismans. "Now, remember, don't touch anything, especially these ones!" he warned, pointing to a cluttered table in the back before being called away by Lan Xichen for engagement ceremony preparations.
Sizhui, ever dutiful, assured him, "Yes, baba." Jin Ling, however, couldn't resist a jibe, "I'll make sure your second crazy son doesn't mess with them." Jingyi immediately retorted, "I should be the one making sure you don't mess with them, young mistress!"
Hours later, the endless waiting began to fray their nerves. "Why is it taking Baba so long?!" Jingyi complained. Jin Ling, ever the pragmatist, scoffed, "Idiot! They're talking serious matters like..." Sizhui finished his sentence, "Uncle's and Huan Uncle's engagement ceremony."
Their boredom was suddenly broken by a strange sight. "Ge, look, there's water leaking from the walls!" Jingyi pointed, a stream of clear liquid cascading down a corner of the roof. "Yeah, really!" Jin Ling exclaimed. Curiosity piqued, the four decided to investigate. As Ouyang Zizhen cautiously approached, he missed a puddle on the floor, slipped, and landed with a loud thud—directly onto Wei Wuxian's forbidden table. "No!" Jingyi shouted, but it was too late. A blinding white light erupted, engulfing them all.
