Chen Mobai decided to stay.
Tianhe Realm is his greatest opportunity. There is no doubt that he will spend a long time in this world, and in this world full of battles and danger, he can't always keep hiding.
Defending Green Light Island this time can give him a direct view of the large-scale battle level of this world.
Moreover, with the Divine Wood Sect taking the lead, such opportunities are not plentiful.
Even if the Divine Wood Sect can't hold on in the end and has to retreat through the teleportation array, it will surely cause a great commotion, which cannot be hidden. He only needs eight seconds to return to the city. When the time comes, he can dig a hole under his wooden house. If the island is truly breached, he can still hide for eight seconds without any problem.
