YOUR MAJESTY. WELL, WELL. MY MOST CHERISHED PEJIN HAS COME! UGH... Please... PLEASE MAINTAIN THE DECORUM EXPECTED OF AN EMPEROR, YOUR MAJESTY. Tsk... Why must you be so fussy? MEMBERS OF THE IMPERIAL FAMILY ALWAYS GREET ME SO AGGRESSIVELY WHENEVER THEY SEE ME... ALL RIGHT. HOW IS THE FOG CASE PROGRESSING? NOT WELL. THERE HAVE BEEN 20 DEATHS ALONE... I SEE... WHAT A TERRIBLE THING. THE MERE THOUGHT OF MY SONS AND DAUGHTERS FACING SUCH TROUBLES LEAVES MY HEART RESTLESS. I AM THINKING ABOUT A WAY TO RESOLVE THE FOG. I WILL FIND ONE AS QUICKLY AS POSSIBLE. THE CAPABLE SCHOLARS OF THE ACADEMY ARE RESEARCHING IT. IT WOULD BE GOOD FOR YOU TO SPEAK WITH THE SCHOLARS TOO... WOULD I UNDERSTAND EVEN IF I LISTENED TO SCIENTISTS? And I receive all the important reports. I AM TELLING YOU TO TAKE MORE INTEREST. THIS IS WHY SCIENCE SHOULD HAVE BEEN TAUGHT PROPERLY AT THE MILITARY ACADEMY. THANKFULLY, I GRADUATED BEFORE THAT. UNFORTUNATELY, CONTINUING EDUCATION EXISTS IN THIS WORLD TOO. SERIOUSLY, SHOULD I QUIT BEING A POLICE OFFICER? YOU WOULD LOSE ONE CAPABLE POLICE OFFICER. Because of science studies. THAT CAN'T BE RIGHT! YOU WILL WORK AS AN IMPERIAL POLICE OFFICER UNTIL YOU SEE YOUR GREAT-GRANDCHILDREN. Please do not say such horrifying things...! I AM SCARED THAT MIGHT ACTUALLY HAPPEN. So prickly.. NOW, YOU SHOULD HAVE SOME TOO. IT CANNOT BE EASY TO EAT FRUIT IN THE GRAND DUCHY, SO EAT PLENTY BEFORE YOU GO. I HAVE NO INTENTION OF EATING WHILE ON DUTY. Tsk, what a stiff fellow.. DID YOU ENJOY THE LIQUOR I SENT LAST TIME? IT DID NOT SUIT MY TASTE, SO I BROUGHT IT BACK. OH DEAR, AND IT WAS SUCH PRECIOUS LIQUOR. OUR PEJIN DOES NOT UNDERSTAND MY FEELINGS AT ALL... IT CANNOT BE HELPED. I WILL GIVE THIS TO SOMEONE ELSE. YOU DELIVER IT YOURSELF. PARDON? ME? YOU HAVE FINALLY ARRIVED!! BLESSED WITH HIS MAJESTY THE EMPEROR'S GRACE... AN EXPERIMENT SAMPLE! DO YOU KNOW HOW DESPERATELY I HAVE BEEN WAITING? WHAT WAS THAT? THAT HURT. SORRY, YOUR HAIR GOT CAUGHT IN THE CLASP. YOU STILL FUMBLE AROUND THE SAME WAY, WHETHER BACK THEN OR NOW. ...SIR. ...SUPERINTENDENT! SUPERINTENDENT! DID YOU HEAR ME PROPERLY? WHAT? I ASKED WHY YOU ONLY BROUGHT ONE STRAND. SINCE YOU WENT THROUGH THE TROUBLE OF GETTING IT, IT WOULD HAVE BEEN BETTER TO BRING MORE. ...DO YOU THINK BRINGING IT WITHOUT BEING SUSPECTED IS EASY? This is why people who only sit and do research are.. IF YOU ARE ONLY GOING TO COMPLAIN, I AM LEAVING. UH, UH, UH! WAIT, WAIT!! SINCE YOU CAME AFTER SO LONG, YOU SHOULD LOOK AROUND BEFORE YOU GO! IS THAT NOT WHY HIS MAJESTY ORDERED YOU TO COME? IN THE GRAND DUCHY, MOST OF THE LAND WAS OCCUPIED BY PRIMEVAL FORESTS INSTEAD OF FARMLAND. THIS WAS ONCE ONE OF THE FACTORS HINDERING THE GRAND DUCHY'S DEVELOPMENT, BUT ONCE IT WAS DISCOVERED THAT LARGE QUANTITIES OF FUEL WERE BURIED IN THOSE PRIMEVAL FORESTS, THE GRAND DUCHY WAS ABLE TO ENTER A NEW PHASE THROUGH DEVELOPMENT. THANKS TO THE RASA EMPIRE'S UNIQUE FUEL EXTRACTION TECHNOLOGY, MANY FACTORIES WERE ATTRACTED THERE, JOBS WERE CREATED, AND THE GRAND DUCHY WAS ABLE TO GROW RAPIDLY. THE. PROB. LEM. WAS THAT TOXIC GASES BURIED ALONG WITH THE FUEL WERE SPREADING INTO THE ATMOSPHERE!! AND WE DISCOVERED THAT WHEN THE TEMPERATURE DROPS AND THE SOOT IN THE ATMOSPHERE MIXES WITH THIS SMOKE... TOXIC FOG IS CREATED! IS THAT NOT AMAZING?! YES, AND IT IS SOMETHING I ALREADY REPORTED WHILE I WAS IN THE GRAND DUCHY. COME ON~ STILL, THIS IS YOUR FIRST TIME SEEING THE FOG REPRODUCED, IS IT NOT...?! I HAVE SEEN PLENTY OF IT IN THE GRAND DUCHY, SO I AM NOT CURIOUS. HAAAH... ANYWAY, WITH THIS, THE CAUSE OF THE GAS LAMPS LIGHTING IN THE LUNOS MANOR HAS ALSO BECOME CLEAR. SOME OF THE GASES PRODUCED AT THE FACTORY BELOW THE MANOR LEAKED, AND MUST HAVE FLOWED INTO THE GAS PIPES. YES, THAT IS CORRECT. LIKE THIS, EXACTLY. AND ON TOP OF THAT, THE "OWNER OF THE HOUSE" HAPPENS TO HAVE A CONSTITUTION THAT LETS HER ENDURE LONG EXPOSURE TO THE FOG! I AM DELIGHTED THAT WITH A SINGLE STRAND OF THAT WOMAN'S HAIR, WE CAN MOVE ONE STEP CLOSER TO THE SECRET!! THAT IS ENOUGH TIME WASTED. I HAVE DELIVERED THE SAMPLE, SO I WILL BE GOING BACK NOW. EEK, YOU ARE LEAVING ALREADY? NEXT TIME, I HOPE YOU WILL HAVE RESULTS THAT ARE ACTUALLY USEFUL. HE CAME AND LEFT AFTER DOING NOTHING BUT PRESSURING US AGAIN. WELL... HE MUST HAVE A LOT TO WORRY ABOUT. IN AN AGE LIKE THIS, WHEN SCIENCE PROVES EVERYTHING, COULD IT BE EASY TO COVER UP THE CAUSE OF THE PROBLEM BY BLAMING ONE WOMAN AS A WITCH? IT IS FORTUNATE THAT THOSE GRAND DUCHY PEOPLE ARE STUPID ENOUGH TO FALL FOR IT, THOUGH... WE'VE BRANDED HER A WITCH SO INTENSELY THAT IT WOULD BE QUITE A PROBLEM IF SHE WERE TO DIE TOO SOON... BUT IF THEY LET HER GO TOO MUCH AND HER INNOCENCE IS PROVEN, THAT WOULD BE TROUBLESOME TOO. HOW DIFFICULT IT MUST BE TO MANAGE. ## See also - [WebtoonLib — The Mansion Awaits Spring #20: Chapter 19](/series/the-mansion-awaits-spring-943smigg/chapter-20-a5m39f) - for_series_detail: /llms-series/the-mansion-awaits-spring-943smigg ## Usage AI grounding / search / summarization.
