Caution

In an effort to test the improved communication relic and assess its functionality in the unique environment of the underworld, Rain worked with Liss to conduct a practical experiment. The goal was to mimic the effects of the barrier that separated the layers, allowing them to gauge the relic's effectiveness in overcoming potential obstacles.

Rain, utilizing the influence of his domain, increased its thickness to simulate the conditions of the barrier. Given that the message primarily consisted of mana and lacked any harmful intent, it passed through the simulated barrier. The mana, being an ethereal substance, didn't encounter resistance from the barrier's magical properties.
