Ye Chen looked at Cai Meng'er, wanting to see how she would choose.
Cai Meng'er hesitated as well.
Cai Meng'er knew that with her real strength, she actually shouldn't have made it to the fourth region. It's all thanks to Ye Chen that she could reach here.
Going further, Cai Meng'er has no confidence at all.
And now, she has obtained a defensive artifact, which makes the trip to the "Ancient Forbidden Grounds" worthwhile.
Cai Meng'er's only concern is that she hasn't met her sister Cai Xiao'er yet. Otherwise, she would have already teleported to the safety zone.
After hesitating for a long time, Cai Meng'er finally made up her mind: "Staying here won't help; to meet Xiao'er, I might not even find her in the fifth region, perhaps only in the sixth region. It's also possible that Xiao'er has already teleported to the safety zone and is no longer exploring other parallel spaces."
