Tried the Ultimate Rare Mushroom Medicine! 🧪

I'm currently playing with the goal of completing the 'Solo BBQ' mushroom encyclopedia. To fulfill the mission of lining up 20 'Solo BBQ' mushrooms, I've been waiting for the last two to sprout for the past two days. Reaching Cultivator Rank 40 allowed me to purchase the 'Ultimate Rare Mushroom Medicine'. They say this drastically increases the spawn rate of rare mushrooms for a very short time!! So, I spent 24,000 NP to buy it and gave it a try. This is the screenshot after setting the Ultimate Rare Mushroom Medicine before playing an ad video and then playing ads twice!! What do you think? Any remarkable effects... not at all 😢 Does it seem no different from the regular Rare Mushroom Medicine to anyone else? 😅 (For reference, the 'Solo BBQ 20' at the far left of the back row is locked and was already there before using the Ultimate Rare Mushroom Medicine.) In the end, even after using the Ultimate Rare Mushroom Medicine, no more 'Solo BBQ 20' mushrooms sprouted 😭 If I'm going to spend NP, I think it's better to invest it in enhancing the rare mushroom rate boost. The days of waiting for 'Solo BBQ 20' continue.
