Classic of Mountains and Seas, Randomly Select a Tattoo of a Strange Beast

[Decisive killing + not brainless + tight rhythm] Su Chen was at the bottom of Qinglan College for three consecutive years and was ridiculed as a waste every day. Until the age of 18, the academy's monthly Xuanwen suitability test... When he opened the "Book of Mountains and Seas" that he accidentally obtained a few years ago with full hope, what he got was the pig-shaped alien beast "Dangkang", which was jokingly called "Domestic Pig Tattoo"? In the academy test, Lin Langtian's third-grade "Qingfeng Eagle" overwhelmed the audience. When it was Su Chen's turn, he had no hope and silently activated the Dangkang Xuan Pattern. But I didn't expect it! Instantly, the golden patterns flowed, and a huge pig-shaped shadow enveloped the whole place, and auspiciousness overflowed. "This useless tattoo... Actually triggered a strange phenomenon in the world?"
