"Kai! Come here. I think I have found something." Isabelle shouted. Although most of the ornaments were already covered with dust, she could still somehow figure it out due to the slight difference from an ordinary wall.

After wiping out the dust with her hands, she saw a certain symbol.

Hearing her voice, he quickly came to Isabelle to see what she found. "This is a symbol?"

The drawing consisted of a few horizontal lines with a dot between them.

"I am not sure." Isabelle shook her head. "I thought it was a morse code at first, but the dot and the line were not aligned. So, I tried to see the other symbols, but they were in a similar pattern with lines and dots. Maybe a language?"

"I am not very sure." Alex shook his head. "Can you find something on the internet? Maybe a published paper or record?"

"I have tried, but I can't find any related results about this. I can find a few pictures of this, but I don't think I can find anything more than that." She was slightly disappointed since there was no use in her finding this thing.

"Well, the internet has already found this so that we can ask someone in the base regarding this symbol." Kai nodded, assuring her it was fine. However, a weird feeling suddenly crept in his heart as if something was calling for him.

"Kai?" Noticing this, Isabelle frowned and checked his body.

"Do you find something? Or maybe hear something?"

"No. I didn't hear anything weird, but there is this feeling that makes me a bit anxious." Kai pressed his chest while Isabelle checked his face. He looked a bit pale, so she tried to help him sit on the ground.

"What is that feeling earlier?" Kai took a few deep breaths. He just got slightly uncomfortable after having that feeling, but he was fine now.

"I don't know. I didn't feel anything." She shook her head.

"There might be something here since you have such a reaction." She narrowed her eyes.

"Yes. I believe so."

"What did you feel? Can you describe it to me?" Isabelle feared that the feeling earlier was a kind of danger during this mission. Hence, it was better to stop the investigation before they got to the point of no return.

"I think I am fine. The feeling itself was a kind of anger. I don't feel there is something wrong with my body from that, only a bit uncomfortable because of it." Kai thought for a moment. "Still, if I need to choose a word to describe it, it's anger."

"Anger?" Isabelle frowned.

"Yes." Kai paused. "That anger is not directed to me. No, I should say that the one making this symbol was angry. He/she was expressing that in this symbol…I mean, like how a painter or any other creative jobs, they could somehow transmit their emotion when doing their job, right?"

Isabelle nodded in agreement.

"It's a kind of like that."

"It still doesn't make sense. Why could you feel it, but I couldn't? If it's something like that, I should be able to feel it too."

"Don't ask me."

"Besides, the symbol is literally on the top corner of a corridor. Are you sure this is it?" She asked again, confirming everything.

"Yes. The feeling indeed came from this symbol."

"I still can't understand the situation. Should I call Evan here?"

"I think I am fine. I don't feel anything more right now, so maybe it's a one-time thing."

Isabelle remained hesitant, but she decided to nod her head, trusting Kai's decision. "Alright. But I should keep accompanying you while we are looking around. If we pass Tasha, I will hand you over to her."

"Yes, thank you." Kai took a few deep breaths and rose from the ground. He stretched his body a bit to see if there was anything wrong or not.

After confirming there was no more discomfort, he nodded to Isabelle as if saying he had recovered.

"How many symbols have you found?"

"Let me calculate the symbols in this room." She narrowed her eyes while beginning to scrub the sand off the symbols to see whether they were really a symbol or not.

In the meantime, Kai checked all the symbols to see whether he would feel the same thing again. He even helped Isabelle in scrubbing the dust off.

Unknowingly, they had spent a few hours just to clean them up, but the result was amazing.

Isabelle and Kai had their back touched as they looked around.

"This…Do you see what I see?"

"Absolutely. I think we need to call everyone else." Kai nodded with a serious expression.

"I agree, but don't you want to count them first?" She asked. "I can help you there. And you don't have any more discomfort, right?"

"Yes."

"I believe this is a kind of language," Isabelle said while counting the symbols in the corridor.

"I have the same opinion, but there is nothing like that on the internet. If we have some kinds of experts deciphering the symbols, we might be able to learn the truth about what happened."

"Indeed. Maybe they did find this back in the days, but their research disappeared when the world became a ruin. After all, other than those that were already spread over the internet, most of the classified data were destroyed when the magical beasts overturned the civilizations."

"Yes. They saved it online after all. Well, I can certainly agree with that kind of treatment since it's easy to get into their online database. But now we are completely clueless about this." Kai let out a long sigh.

"Haha…We can only work hard for it." Isabelle brushed the matter off with a laugh.

"By the way, how is your relationship with Evan? Everything is fine, right?" Kai asked.

"Yes. Evan always hesitated in our relationship because we were Zodiacs. However, thanks to your medicine, he stopped hesitating, so our relationship isn't that brittle anymore. Thank you."

"No problem. I still want to laugh at the fact that we first start from oppositions…Especially due to an idiotic reason." Kai chuckled.

"I am embarrassed to see the past me. To think I was that immature. Well, that loss woke me up, and I am glad to know you as a friend."

"Me too." Kai smiled. "Well, if you have trouble, just call me, especially if the matter is regarding Evan. I will kick his ass for you."

"You don't need to. My kick is the strongest…For various reasons." Isabelle smirked.

"Evan seems to be scared of you that much. I wonder what will happen when…Never mind." Kai decided to stop before he mentioned the matter about the little girl from the EU Base.

"If you are talking about Elisa, I don't have a problem myself. Although it feels suck, I can somehow understand if that happens. I mean, in the past, I was taught to be someone's mistress because I didn't have talent, so now, I don't really have a problem as long as he is open to it." She shrugged. "Well, I have talked to Michelle, Tasha, and Ayaka and learned a lot from them. I just need to make sure he doesn't stray from his path. Besides, like you, he also respects me as a woman and acknowledges my opinion. As long as he doesn't have a drastic change, I believe our relationship will remain the same."

Kai smiled and nodded. "I wish you the best."

"Thank you." Isabelle smiled. "By the way, I have finished counting. There are seventy-four symbols."

"Hmm?" Kai furrowed his eyebrows.

"What is it? Do you find something?"

"I don't know. I feel like the number is very familiar." Kai frowned. "Where did I hear it…No, I didn't hear it, but…"

After contemplating for a few minutes, he suddenly picked up his device and browsed the research paper again. "Take a look at this."

Isabelle came closer to him and looked at the article.

"There are many Nazca Lines. Hundreds are simple lines and geometric shapes, but more than seventy are zoomorphic designs. Do you mean these zoomorphic designs? What is zoomorphic anyway?"

"It derives from the Greek, meaning animal and shape or form. It can be considered a symbol for an animal." Kai explained.

"So, does this mean something?" she asked.

"I think so. They might have the same number as the Nazca Lines for animals, so I think the Nazca Lines and these symbols are related. For example…"

Hearing this, Isabelle continued his words and came to a realization. "They are the names for animals?"

"Yes." Kai nodded with a serious expression.

"Then, do you find anything about the earlier feeling?"

"No. But I still believe that symbol is somewhat special."

"I will take their pictures and mark the one that you deem special. I want you to ask Evan to check your condition and ask them to come here." Isabelle still felt concerned about his condition even though there was nothing happening during the past few hours.

"Alright, alright. I will do that."

"Then, hurry up." Isabelle rolled her eyes.

"Fine." Kai then walked across the corridor, heading straight to Evan's position with his ears as his guide.

In the meantime, Isabelle picked her device and started recording a video while taking some photos. She tried to look at the symbol that made Kai weird from any angle, but nothing happened to her, so she thought Kai was a special case.

Just like how he solved the mystery in Easter Island, he might probably get something from this place as well.

She shrugged and continued her job.

Kai also found Evan after walking for a few minutes.

"Evan. Can you take a look at my condition?!" Kai shouted from afar. His voice echoed in the corridor.

But to his surprise, Evan didn't answer him or anything as if he didn't hear him.

"Evan?" Kai furrowed his eyebrows. According to his ears, there was nothing wrong with the sound in Evan's body. It was normal, but Kai still took out his swords while approaching with caution.

Suddenly, Evan turned around.
