It turned out that, ten days ago, Invincible Base had emulated Shadow Base by having Peanut and Emerald Feather establish a sub-base. However, the reason behind Shadow Base creating a sub-base was due to stockpile and in preparation to advance into Left County. After hearing this, Lin Wu felt that having Peanut and Emerald Feather set up a base was purely an act of exile.
All of this stemmed from considerations of Invincible Base's strategic position.
Shadow Base had strategic plans to move into Left County, an idea also presented by Invincible Base during their strategic meeting. However, they lacked information and strength, and after witnessing the patrolling zombie tides, they retreated from that plan. They then proposed the idea of building a beautiful home with Invincible Base at its center at the strategic meeting.
