The bomb of Prometheus.

"That is to say, plants don't have eyes. But Monster B, who took over the nervous system of animal-type monster A, is clearly looking around with those eyes. The amount of information picked up by the eyes is enormous. The processing capacity of plants, the most primitive organisms, can't keep up. So Katerina thought that Monster B had something beyond plants. At that point, she thought it was a 'brain'."

Kim Rok-su stopped talking here. He looked at Choi Jeong-su. He had been listening attentively, but when he heard the word 'brain', his expression changed all at once.

"Brain!" Choi Jeong-su shouted. "That's ridiculous!"

"We found something like that in this experiment. I don't know if it's exactly the same as an animal brain, but the water spirit first confirmed Monster A's brain, then went into the plant part to look for Monster B's brain, and found it. By the way, it seems that spirits never forget what they learn once."

"...Don't they forget?"

"They say they remember like to copy everything."

As he spoke, Kim Rok-su couldn't help but think of Cale. It would have been great if he could respond to things as easily as the spirits, and process everything in parallel.

"The spirits have confirmed Monster B's brain, as well as its location and size. Now we have set our final goal. We will destroy Monster B's brain. From now on, we will plan all of our plans with that goal in mind."

Kim Rok-su let out a deep sigh. What I had just explained was the outline of the plan, but the conflict it took to get it through was quite psychologically tough.

Exploring the monster's body to find its weaknesses. This was a psychological burden on a whole different level to fighting the monster directly. Kim Rok-su in particular had never been on the front lines in a fight. It was completely unbecoming for him to think about the dignity of living things.

"Is that the plan? The one you told me to keep quiet?"

"Yes. There's a good chance that Monster B can control the Monster A's ears as well. It would be a problem if that fellow overheard me and put up a defense around the brain. That's why I tried my best to hide the truth of the plan."

"... Was it actually quite difficult?"

"Though it just looks like we were pouring water over the head of that fellow."

"Ah, ...yeah."

Choi Jeong-su looked away from Kim Rok-su. That was exactly what Choi Jeong-su had been thinking when he was looking at the plan in progress.

"The rest is for the wind spirit to receive the report from the water spirit and send it to Katerina. She just have to repeat that. Katerina is the only one who can hear the spirits' voices, so it's the biggest burden on her, but she did it in silence."

Kim Rok-su calmly explained the story, but it was very difficult to get Kim Woo to listen the plan. It was also difficult to explain how he came to that conclusion, but the way to confirm it was based on believing in Katerina and the spirits. With the persuasion of Ki Hi-ran, who intervened, and Lee Su-hyuk, who joined them along the way, they finally managed to put the plan into action. However, Kim Woo wasn't denying everything. What he had a problem with was Katerina, and the method of confirmation that forced them to rely solely on her.

As a result, Kim Rok-su was placed in Kim Woo's custody and protected within his camp. And Katerina was assigned a guardian as a bodyguard.

And so the plan was put into action, and the results are steadily piling up. However, as Katerina said, the proof won't be known until the monster is cut open.
