Jiang Han looked at the five tunnels with a thoughtful expression.
A moment later, he walked to the closest tunnel and began to examine it.
Similarly, Ying Si, Yu Jing, Tang Feng, and other formation masters also began to study the tunnels.
'The tunnel entrance is a formation with twenty-three nodes.' Jiang Han thought and subconsciously frowned.
Ordinary level one formations had nine nodes.
Similarly, level two formations had eighteen nodes, twenty-seven nodes for level three formations, thirty-six for level four, and forty-five for level five.
Considering that, Jiang Han concluded the entrance formation was non-standard.
After all, twenty-three nodes were somewhere between a level two and a level three formation.
'It's five nodes more than a level two formation but four nodes less than a level three formation. Considering that, is it a level two or level three formation?' Jiang Han wondered.
