Although ordinary cultivators—even disciples of super sects like the Mist Hidden Sect and the Dark Pavilion—were in great danger in the Sacred Ruins Abyss after breaking through to the Twenty-seventh Heaven of Near-Saint, Sacred Heart Sect cultivators were far stronger. By cultivating the Sacred Heart Art and the Great Thousand Worlds, they had opened up multiple Small Worlds. Shen Wei and the others, for example, could ignore many of the dangers inside the Sacred Ruins Abyss. They still couldn't enter it freely, but they could reach many places even without the help of the Creation Divine Tree.
The reason Shen Wei and the others had brought the Creation Divine Tree with them wasn't to use it to avoid the many dangers in the Sacred Ruins Abyss. More than anything, they had wanted to use it to track Ling Tian and the others. They hadn't expected the Creation Divine Tree to suddenly "rebel," leaving them with only one path forward: following Ling Tian and his group.
If Shen Wei and the others could ignore many of the dangers in the Sacred Ruins Abyss, then Sacred Heart Sect cultivators who had reached the Twenty-eighth or even Twenty-ninth Heaven of Near-Saint could do so even more. They could even enter the Sacred Ruins Abyss freely, which meant cultivators of that level could pursue Ling Tian and the others inside.
If those cultivators tracked them down, then even if Ling Tian completed his breakthrough and reached the Twenty-sixth Heaven of Near-Saint, he probably wouldn't be their match. They might not even be able to contend with them after reaching the Twenty-eighth Heaven of Near-Saint. Reaching that level would undoubtedly take a long time, which meant that in the meantime, they could very well be hunted down and captured by the powerful Sacred Heart Sect
