Indeed, at this moment, the Thunder Sword True Man is not as confident as he appears.
If it weren't for his previous experience, having directly wielded the Two Diagrams Map, an Immortal Treasure of Quasi-Taoist Monarch level, to enter the formation, he would surely be full of confidence.
However, after the previous experience, although he successfully escaped, he naturally raised the level of danger he's perceived about the Eight Trigrams Divine Array much higher, so this time he must ensure to accomplish his main objective in the formation.
Thus, even though he is confident, caution is the best policy; he still decides not to allow Water and Fire Taoist to join him in action, avoiding delaying matters or encountering unexpected events.
