Lin Chen had a Consciousness Puppet enter the Moon Shadow Pavilion, so he understood more or less the reasons behind Red Soul Hall's attack on Divine Sun City.
The ambitions of these large powers in the Eastern Domain were not limited to the present; they planned to advance toward the Southern and Northern Regions, and they naturally wouldn't overlook the strategically important position of Divine Sun City.
The Jade Cauldron Sect had already been dragged into the quagmire of the Eastern Domain powers' struggle for Divine Sun City, and now, even if they wanted to disentangle themselves, it probably wouldn't be an easy matter.
Therefore, rather than retreating, Lin Chen might as well take advantage of the situation to lead the Jade Cauldron Sect toward a broader world.
The first step the Jade Cauldron Sect needed to take was for Lin Chen to have a strong identity within the Formation Sect, which could then serve as a springboard to aid the Jade Cauldron Sect.
