Alfonso beckoned a Beastmaster to come forward, pointing to the man's dragon bones and saying, "Unlike our combat armor, the Beastmaster's equipment not only contains the mother body of the Hive Parasite, but also a whole Tesla Parasite inside."

“Just over two years ago, with His Majesty’s approval, a group of scholars from Muxi University secretly established an electrical engineering research institute to study electric current. They inadvertently discovered a new way to use electrical energy,” Alfonso said uncertainly. “It seems that this method can affect something in the nervous system…”

"Let me explain."

The beast tamer lifted the dragon bone's helmet, combed the parasite's limbs back, revealing the face of a slightly immature young man.

He said, "We have linked the dragon bone with the honeycomb and the Tesla, and by utilizing the characteristics of these three parasites, we have achieved the goal of controlling the war beast with radio waves."

Looking at the young man's face, Cumberland said with some surprise, "You don't look like a soldier."

“Joonella Tilleya, I am a second-year student majoring in electrical engineering at Musi University.”

Cumberland turned to Alfonso, his face full of displeasure: "I had no idea that the kingdom was in such dire straits that it needed student soldiers."

Alfonso shrugged: "Sir, it's not that we want these students to go to the battlefield, but the equipment they're wearing is something no one in the army knows how to use."

Joonella patted his chest and gave a barely passable military salute: "It's all for the glory of the Holy King!"

Cumberland sighed. "Go on."

"Scholars at Muxi University have discovered in experiments that when the Tesla parasite discharges electricity, it generates a force that can affect the magnetic field."

"This electromagnetic force generates electromagnetic field lines, and at both ends of these field lines, free charged particles can be continuously attracted to grow, eventually forming plane waves of different frequencies and wavelengths in various directions of space..."

With a headache, Cumberland rubbed his forehead and shouted, "Change it to a language that humans can understand!"

Joonella said helplessly, "To put it this way, the Tesla parasite can generate an electrical signal, like a sound signal, but this signal is chaotic and difficult to control."

"So, we first link the Tesla parasite with the keel parasite, and then have the user wear the keel, thus achieving neural connection between the person, the keel, and the Tesla."

"Humans can transmit commands from the brain to the keel through neural hooks on the keel. The keel then transmits these commands to the Tesla parasite, which can then release a fixed current and form specific electromagnetic waves according to the human's commands."

Cumberland questioned, "But you still haven't explained how you control the war beasts."

Joonella made a gesture to calm down: "My lord, I'm about to explain."

“Based on humans, keels, and Tesla, we have now connected to a fourth object – the hive parasite.”

"As is well known, the honeycomb parasite is a special type of nematode, which consists of a mother and daughter. The mother can connect with specific daughters and perform transcription, translation, and targeted transmission of information between the two objects."

Seeing the renewed impatience on Cumberland's face, Alfonso said to Joonella, "Keep it simple."

“Okay, we can think of the hive as a megaphone that can lock onto a target. It can transmit the thoughts of the mother host to the daughter host in the form of infrasound, and form the same meaning in the daughter host’s nerve center.”

"However, this method of communication has many drawbacks. For example, it has a short transmission distance and the sound frequency it transmits has a certain limited range, so it can only be used to form a communication channel between humanoid beings."

"Therefore, the scholars at Muxi University hoped to find a way to transmit information to replace the hive. Thus, they discovered electromagnetic waves."

Ioonera pointed to the dragon bones on her body: "Human commands are converted into special electromagnetic waves by the Tesla parasite, and then transmitted from the mother to the offspring through the information channels between the hives."

Ionella turned his gaze to a giant wolf not far away. As the antennae on its dragon bone limbs trembled slightly, the giant wolf seemed to hear an invisible voice. It quickly ran to Ionella's side, then obediently lowered its head, lay down on the ground, stuck out its tongue, and wagged its tail.

Under Cumberland's astonished gaze, Joonella raised the giant wolf's head and pointed to a metal ring around the beast's neck, saying, "This object is the Beast Control Ring, also known as the Beast Collar. It contains a culture medium, a Tesla parasite, and a honeycomb sub-organism."

"When the dragon bones on my body emit electromagnetic signals, these signals will be transmitted to the collar of the war beast through the communication channels of the hive."

"These collars contain spikes that can directly penetrate the nervous system of the war beasts. The parasites can use these spikes to make direct neural connections with the war beasts, and these electromagnetic signals are transmitted to the war beasts' brains along with these spikes."

Cumberland asked incredulously, "You mean, these war beasts can understand human speech?"

"No, strictly speaking, that's not the case. These war beasts can't understand complex words or sentences, nor can they communicate with their controllers... Perhaps this explanation is more reasonable: we simply use electrical current to stimulate the war beasts' brains with some not-too-complex commands, so that they can complete tactical actions."
