"[Tower of Adversity]

A large underground comprehensive experimental center built before the Lament. It sank into the sea due to the terrain changes during the Lament, and only recently resurfaced.

This research station has a depth of over ten thousand meters reaching the Moho, and there is a trend to continue to expand downwards. At the same time, there seems to be a periodic echo coming from the deep well, as if it is breathing. Therefore, the deep well has also gained the nickname of the Gate of Hell.

Without a doubt, humans do not have the industrial capacity to build such a facility. At the bottom of the deep well, countless mysteries are waiting to be unveiled...

[Exploration Cycle]

The environment of the Tower of Adversity naturally recovers in a two-week cycle, and the data and monsters will be updated after the cycle is reset. The rewards from the data will also be updated.

[Underground Structure]

The Tower of Adversity has 3 areas to be explored, and each area has 4 depths. Only after the explorer has completed the exploration of the 3 areas at the same depth, can they proceed to explore the deeper layers.

[Lineup Selection]

Exploration requires the formation of 3 teams, each to complete the exploration of 3 areas. The Resonators who have already fought will be locked in the exploration area and cannot participate in the exploration of other areas until the exploration of the 3 areas of the same difficulty is completed. The explorer can choose to manually unlock the Resonators, but after the unlock, the exploration points of the current area will be reset.

[Exploration Rules]

Explorers need to conduct multi-layer exploration in each area, each layer of exploration has a certain time limit. If the exploration is not completed within the time limit, it will be judged as a failure; if all the monsters are defeated within the time limit, it will be judged as a pass.

[Exploration Degree]

When the explorer is exploring the surface layer, the relay layer, and the deep layer, the exploration degree will be evaluated in real time according to the explorer's performance. After the exploration is completed, a fixed amount of exploration points will be settled;

When the explorer is exploring the mutation layer, the exploration should be ended as soon as possible to avoid pollution. The faster the exploration is completed, the more exploration points will be obtained at the time of settlement.

[Residual Echo]

In the research station, each area node will have a Master of Illusion. The Master of Illusion has obtained the enhancement of the Lament's Echo, and has a stronger power than the general monsters, and even has rule-like characteristics (such as enhancement effects). The explorer needs to choose the lineup carefully according to the characteristics.

[Reward Rules]

The deeper the exploration, the more information obtained, the more rewards. Every time a certain exploration degree is reached, rewards will be settled at the end of the cycle; when the explorer has completed the exploration of the surface layer, the relay layer, and the deep layer, rewards can be obtained in advance.

[Ability Limitations]

In the Tower of Adversity, it is not possible to cultivate Resonators, use items, change equipment and Echo during the exploration, and some system functions will also be prohibited."
