Zhan Chen was most proficient in five element tribulation formation because he had already arranged it in the Zhan family estate back in his home town.
But, five element tribulation formation couldn't be considered as a top grade formation technique. So, Zhan Chen decided to skip it as he searched for an ideal formation technique for himself.
Zhan Chen scanned through the difference paintings hung on the wall. His eyes lit up as he saw a painting which was hung at the corner most positio of the wall.
"Eight trigram slaughter formation", Zhan Chen recognised the formation technique immediately. He was somewhat familiar with this formation as it could be considered as one of the most complex formation, he had come across in his life.
Zhan Chen had a solid grasp on this technique. So, he looked no further and pushed his soul consciousness towards the painting where he found the Eight trigram slaughter formation technique.
