Song Shuhang opened a small entrance to the Inner World and said to the Heavenly Emperor, "This is my biggest secret and life-saving trump card. After you enter, please don't destroy it."
Song Shuahang was only being careful because the Inner World's strongest helper, Senior White Two, had fallen victim to the fat ball's schemes, and he did not know how he was doing at the moment.
Otherwise, he would not have had to act with so much caution.
Sister White Dragon quietly turned her head when she heard Song Shuhang introduce the Inner World and said that it was his biggest life-saving trump card, resisting the urge to laugh.
This so-called "biggest life-saving trump card" had almost never actually saved his life.
