The five Students sat in class with other Jo-lan warriors. Harry stared out the window of the classroom with a bored look on his face.
"I understand that Buern and Josec will need to master the Light's Wound as a Dual Type Technique however how are they even supposed to start augmenting their abilities? We've utilized fused Psychorages and have shared similar dreams but we just kinda did all of these instinctively. We don't have much theoretical knowledge of how these things work" Harry recalled admitting to the elders.
"I see. They must have been relying mostly on Luna's and the Masters' abilities to sync their wills and Josec's Eyes Of The Phoenix to generate the form for a fusion psychorage. However that implies that they would be helpless without the Masters' presence. They need to reach a level where they can generate the form of and sync their wills to fuse psychorages" William Fenix said to Master Andrea.
"They have some understanding of affinities and wavelengths" Master Andrea informed the elders.
"One of their predecessors currently inhabits the Book Of Jo-lan. He is currently holding classes on Dual and Delta Type Techniques and I believe they may have encountered him before. At least Josec should have" William Fenix said.
As Harry sat staring at the window absent mindedly, Josec recalled his surprise in encountering their tutor. He recalled telling the others of his vision of Ryu's battle against the Sun-Song Devil. Their tutor, Josec had informed the others was the inventor of Delta Type Techniques in Kolmnid.
"Josec, Harry, you seem absent minded. I am about to commence my lesson on Dual and Delta Type Techniques" their tutor called out.
"We're listening Master Ken" Josec called nervously.
"I've been told you have some understanding of wavelengths. Would you mind sharing what you know about them?" Ken asked Josec and Harry.
Josec stood up.
"Wavelengths play a role in determining personality types. When one can utilize an improv of an element different from one's elemental affinity, it implies an understanding of people of that elemental affinity. The variations of wavelengths a person can utilize are dependent on the vastness of their experience. A person with vast experience can adjust their wavelength to suit the battle environment. Unique wavelengths that are outside of an opponent's variety of wavelengths play an important role in deciding victory in combat" Josec explained.
"Hmm, he appears to have a thorough understanding of wavelengths" Ken thought to himself. "Well done Josec, I'm impressed" Ken said.
Josec sat down.
"Today, I am going to teach you the basics of Dual and Delta Type Techniques" Ken said.
The Students listened attentively.
"When Jo-lan warriors fuse their techniques, Dual Type Techniques can be utilized. Depending on the elements involved in performing the technique, the power of the technique can be greatly multiplied" Ken explained.
"What of Delta Type Techniques?" Jason asked.
"When more than two Jo-lan warriors fuse their abilities, Delta Type Techniques are born. Delta Type Techniques are more powerful than Dual Type Techniques or Solo Techniques however to utilize them involves a great deal of comprehension over the principles of both elemental affinities and wavelengths. They can usually only be utilized by people with a great affinity for one another" Ken explained. "Some of you may have utilized Dual and Delta Type Techniques before in one way or the other" Ken said.
Josec, Harry, Buern and Estelle recalled the torrential flame stream they generated to break out of Fencer's Cave and they all recalled the various Psychorage Fusions they had employed in combat against the generals.
"Some elements depending on how they are used can greatly amplify the abilities of other elements. These are known as Amplification Dual Type Techniques. Others can serve as catalysts; these are known as Catalyst Dual Type Techniques. There are some Dual Type Techniques that also result in the birth of a new element; these are known as Transformation Dual Type Techniques. For instance the fusion of wind and flame results in the amplification of fiery techniques. When earth and fire techniques are fused, Molten Techniques are born. When water and ice are fused, we have Snowstorm techniques. Heat can also serve as a catalyst to a storm. Do you understand? In a sense, it's like forging an alloy. Though of course, if elements that do not complement one another are fused, the technique could become unstable, become weaker than a Solo Technique or even cancel itself out" Ken explained.
Buern and Estelle seemed to understand this lesson instinctively. Harry and Josec knew about Amplification Of Techniques via complementary elements and they had heard of heat serving as a catalyst to a storm from the Masters right before they prepared to confront Aesakal so they were aware of catalysts. However, they were new to the concept of fused elements giving birth to completely new elements though they were aware of alloys from their lessons back in Ferus Village.
Ken led the Students to an arena to practice their techniques. First, they were to demonstrate Amplification Delta Type Techniques. The five Students demonstrated their wind and flame combination techniques. Next, they were to demonstrate Transformation Delta Type Techniques. Buern equipped her fiery improv. Estelle and Jason did not equip improvs since Estelle had a natural affinity for flame and Jason had an affinity for Forest and Earth. Josec and Harry equipped Earth improvs. The three boys generated great blocks of earth and the girls melted them under intense heat thus generating Molten.
"That's very good. Now you will demonstrate Catalyst Delta Type Techniques" Ken said.
Buern returned to her normal state and began to diffuse a large amount of soil water into the air. Harry flowed air into the water particles. Jason equipped a fiery improv and began to heat the air and water and Josec ionized the mixture with his lightning. Storm clouds were generated and they began to rumble and discharge lightning.
"Well done! The five of you are very advanced in the Jo-lan Martial Arts. All you need to know now is this. Since elemental affinities play a role in determining personality types and wavelength variations are determined by the vastness of one's experience, joki in essence is also a manifestation of will" Ken said.
"I see" Buern said in amazement.
"In other words, to fuse your joki is to fuse your wills" Ken said.
"Thank you Master Ken" the Students bowed respectfully.
William Fenix observed them secretly.
"It looks like they are advanced in the Jo-lan Martial Arts. All they needed was to polish their theoretical knowledge of the Art. I suppose it's about time I tested them" William Fenix said as he approached them.
"Master William" the Students noticed his presence.
"I believe it's about time you began practicing for the Light's Wound Technique" William Fenix said. "I challenge you two, Josec and Buern to a duel" William Fenix said.
"WHAAAAAT?!" all the Students exclaimed in shock.
