The blue sky turned red and the flowers slowly turned red. Red liquid? No.. It's blood. The flowers were filled with blood.
Nacht was fighting Damnatio, who got turned into Paladin by Lucius, with Black Bulls, his squad.
As Nacht was fighting, he noticed the sky and the white flowers turned red, which was an unexpected thing. But, he knew who did it, he knew.
Nacht's eyes darted around, trying to find the person or rather you. You were the one he's looking for.
Nacht's eyes landed on you as he found, seeing you there fighting the Paladins, he could hear you laughing and you saying.
"๐๐จ๐ฆ๐ ๐จ๐ง, ๐ญ๐ก๐ ๐ฉ๐ฅ๐๐ฒ๐ญ๐ข๐ฆ๐ ๐ฃ๐ฎ๐ฌ๐ญ ๐ฌ๐ญ๐๐ซ๐ญ! ๐๐ฅ๐๐ฒ ๐ฐ๐ข๐ญ๐ก ๐ฆ๐ ๐ฆ๐จ๐ซ๐!" As you kill the Paladins.
Of course, you were in your psychotic mode, the opposite of the calm and gentle you. Now, you were aggressive and dangerous.
You were fighting the Paladins as you laughed, an evil laugh. You kept killing them as you swung your scythe.
