Angelica acted quickly, using the special tools she carried to carefully disassemble the old machines one by one and store them in her storage space.

The information contained in these devices is too valuable to be lost in the impending collapse.

Her movements were swift and precise, clearly indicating that she was well-prepared for such an emergency.

After finishing packing, she didn't leave immediately; instead, she became even more determined to explore further.

Since such an amazing discovery was made at the entrance to the thirteenth floor, there might be many more undiscovered secrets waiting for her deeper inside.

Angelica adjusted her equipment and strengthened her protective magic in preparation for an even harsher environment.

As she ventured deeper, the surroundings became increasingly harsh, and the whispers grew more frequent and clear, but Angelica remained calm, taking each step with extreme caution.

Fortunately, these whispers were just unconscious whispers, so they had little impact.

Using her knowledge of the abyss, she avoided obvious traps and heavily corroded areas, continuing to venture deeper.

During her exploration, Angelica also discovered some forgotten fragments of documents containing ancient languages ​​and symbols that describe the relationship between the abyss and the unspeakable, as well as the efforts of ancient civilizations to seal or control them.

For her, every page of this knowledge was priceless.

Just as she was about to continue deeper into the fourth level, a strong and clear wave of consciousness came. Unlike the previous whispers, this time it sounded directly in her mind, full of warning.

Angelica stopped in her tracks, a sense of unprecedented vigilance rising within her. Looking at the passage before her, she knew that below lay the fourth level, completely corrupted by something indescribable.

Initially, there were only three levels of the Unspeakable Abyss that could be closed. Over time, this number gradually increased to the current thirteen levels.

The abyss can suppress the indescribable, but it is clear that it cannot suppress it for long. It will inevitably be gradually corrupted and assimilated.

She decided to temporarily withdraw and take the existing findings back to a safe place for careful study.

In the abyss, impulsiveness often means death. Angelica is not reckless; she knows how to weigh the risks and rewards.

After confirming that the surrounding environment was temporarily stable, she quickly returned along the same route, checking again along the way to ensure that she had not missed any valuable clues.

Back in a relatively safe shelter near the entrance, Angelica began to organize and analyze the gains from this expedition.

Every piece of equipment and every document could become key to combating the threat of the abyss.

......

Once Angelica returned to safety in the abyss, her first focus was on removing the influence of the whispers from her body.

Although those whispers did not leave a deep mark on her mind, for someone who had been living in the abyss for so long, any potential mental pollution could not be ignored.

They then immediately began processing the data brought back from the first three floors.

She first thoroughly cleaned and repaired all the equipment to ensure that the effects of the corrosive environment were minimized.

Subsequently, she devoted a great deal of time to studying those fragments of documents, using her extensive knowledge and the Abyss's unique translation tools to decode the ancient texts bit by bit, gradually piecing together those lost historical fragments.

In the process, she discovered several key pieces of information. One was the incomplete record of ancient sealing techniques, which, although incomplete, was enough to inspire her to improve existing defense technologies.

Secondly, there is a description of a special material that is said to be able to inhibit the erosion of unidentifiable substances to a certain extent, making it an ideal material for making advanced protective equipment.

Thirdly, there are clues about an organization that was dedicated to researching and combating the forces of the Abyss, whose members may have left behind more valuable knowledge and technology.

To verify these theories, Angelica decided to conduct a series of experiments.

She began concocting special protective potions, attempting to enhance her equipment with newly discovered materials, and simulating the basic structure of sealing techniques, hoping to create a small-scale experimental protective field.

After confirming that all the data was useful, Angelica took all the data back to the shelter and handed it over to the shelter's researchers for study.

Inside the shelter, the researchers showed great interest in and attention to the data and samples that Angelica brought back.

They quickly formed several specialized teams, each responsible for equipment restoration, document translation and interpretation, new material research, and the practical application of sealing techniques.

The atmosphere in the entire shelter became tense yet full of anticipation because of these new discoveries.

Angelica personally oversees the progress of each research project, working closely with experts in various fields to ensure the accuracy and applicability of the findings.

In the research of new materials, scientists, under Angelica's guidance, have successfully refined a compound called "shadow resist agent". This material has shown strong resistance to unidentifiable energy in experiments, laying the foundation for the manufacture of a new generation of protective equipment.

Meanwhile, the team developing the sealing technique also made a breakthrough inspired by Angelica's ancient documents.

Combining modern divine magic theory, they designed an improved defensive array that can not only effectively block the intrusion of whispers, but also weaken the power of abyssal creatures to a certain extent.

After numerous simulation tests, the initial prototype of the magic array showed encouraging results in the laboratory.

The translation of the documents revealed more secrets about the ancient organization, the "Night Watchers."

This organization not only possesses ancient wisdom for fighting the abyss, but has also left behind a series of hidden relic coordinates, which are said to contain the core results of their research.

Angelica decides to personally lead an expedition to search for these ruins, following the guidance in the documents, hoping to find more keys to fight against the abyss.

Based on the deciphered coordinates of the ruins, Angelica and her team quickly located one.

Looking at the ruins before her, Angelica sighed. She had been to this ruin before, but she never expected that there was another ruin hidden beneath it.

This is like a nesting doll.

According to the information, Angelica quickly arrived at the entrance to the ruins. It was clear that the visible ruins existed first, while the ruins below were built by that unknown organization.

Looking at the mural in front of you, who would have thought that it was a hidden entrance?

As the door slowly opened, Angelica suddenly frowned, because she sensed a whispering presence. Could it be that below lay some unspeakable ruins?
