Su Jiu closed her eyes and quietly began to consider what she would have done if she had designed this array.
First, this was a three-ring array. The main reason it was called that was that its three spaces were actually connected. In books on formation arts, those three spaces were also called primary spaces.
The numerous secret chambers hidden within a three-ring array were called subsidiary spaces. Beyond those, there were also numerous intricately interwoven arrays, which were precisely what connected the three spaces. Naturally, punishment teleportation arrays were among them. As the name suggested, they made you undergo something before teleporting you to your intended destination.
If someone ignorant of formation arts mistakenly entered the wrong punishment teleportation array, a nightmarish baptism awaited them. Someone versed in formation arts would naturally notice the hidden doors, but even a Formation Arts Artist who discovered those doors might not dare enter without any innate arts. After all, whether a pleasant surprise or a nasty "surprise" lay inside was anyone's guess.
Take the cultivators following Su Jiu, for instance. She had long suspected that there might be a first-tier Formation Arts Artist among them. Their level was simply too low, and only by learning from her had they managed to puzzle out a little. Even then, they still could not tell whether resources or magic beasts awaited them inside. They had merely seen that every secret chamber Su Jiu took them to contained resources, and assumed all secret chambers did.
Moreover, this three-ring array was not actually an ordinary one. In an ordinary three-ring array, each of the three ring spaces contained one punishment array and one one-way teleportation array, with the one-way teleportation array in the final ring leading outside.
Yet the designer of this array had added a two-way
