Earth Lord and Wither Witch

I dress up as the poorest lord in another world. The castle is leaky and the people under my command have yellow faces and thin skin. When everyone burned the "Wither Witch" in the execution ground, it was said that everything withered when she touched it. But I stared at the cement that solidified rapidly after she touched it, and excitedly held her hand: "Miss, you have a rare talent that can accelerate the movement of molecules!" Come to our territory, get five insurances and one housing fund, and project dividends. Later, the imperial cavalry came to the border and laughed at me as all my men were freaks. I smiled and pointed at the sharp-eyed women in the front row: "Let me introduce, this one is responsible for missile fuel, and that one specializes in gene editing." "As for the road under your feet - it was solidified by the 'Wither Witch' express." Knight Commander, do you think your armor can withstand molecular-level "accelerated decay"?
