Wink gave the class a few minutes to assimilate the new information before carrying on.
"Due to the Astral Rebirth Path of Power's Sacred Organ being the heart, which increases its functions according to the body's requirement on its own, it is easier for Astral Wave Cultivator to master Wave Burst."
Wink's explanation made perfect sense for the cadets. The Rebirth Heart had always regulated the body's blood flow, increasing it when needed, so it was not odd for it to increase the output of Wave more efficiently than the Evolution Core.
"As for the flaw regarding our inability to keep all the Wave inside the Wave Cloak during Wave Burst. That is where combining the arts came into place."
The cadets saw how the virtual screen above Wink showed two humanoids. One was using Wave Burst, while the other trained in Synergy Flow.
Next, both figures fused, and the class saw how the bursting Wave Cloak grew thicker and its edge denser.
"By mastering Synergy Flow while using Wave Burst, we can limit the amount of Wave dispersed. Of course, training Synergy Flow while your Wave Cloak is bursting is much harder."
Shortly after that, the virtual screen focused on the third humanoid.
"Now that we are over with Wave Burst, it is time to tackle Wave Focus. This art's main principle is focusing our Wave on a single point. If done during Wave Cloak, we will enhance a specific part while diminishing the amount covering the rest of the body."
The virtual screen showed how the humanoid used Wave Cloak before increasing the amount in the right fist. That made the Wave covering the rest of the body grow thinner, diminishing the amount of protection it could provide.
"That is the most basic use of Wave Focus and one that Astral Wave Cultivators must master as it heavily influences a melee battle. However, you are sorely mistaken if you think Wave Focus is just that."
Wink raised his right hand and opened it, showing the palm to the cadets before cutting it with his left index finger. The cut was deep to the point it almost reached the bone.
The virtual screen above them showed a magnified version of the palm, making the edges of the cut clear for everybody.
"Pay attention to the screen and see the might of Wave Focus."
Wink said nothing else before his Essence Wave began to gather in the wound, and not long after, under the awed gaze of the cadets, the cut started to heal with speed visible to the naked eye.
It took Wink less than a minute to heal that wound!
"I used Wave Focus to speed up the regeneration process by giving the tissue more vitality and hyper-activating the red blood cells."
Next, Wink focused his Essence Wave into his eyes and focused on the cadets, making all of them feel that this one could see every corner of their bodies.
"If I focus my Wave into my eyes and the optical nerve, my eyesight improves to a level surpassing that of Old World's telescopes. And the same goes for my other senses such as smell and hearing."
The cadets understood the might of Wave Focus after that description and how amazingly useful it was, both in battle and out of it.
"Wave Focus can also be used for defense, as we can enhance the amount of Wave in our arms before using them to cover our bodies from an attack. Those in higher cultivation ranks can deploy extremely refined uses of this art, which are incredibly powerful."
Wink saw the cadets' attention had peaked and proceeded to deploy a Level 3 Wave Cloak and 200% Wave Burst.
Then under the utterly shocked sight of the cadets, all that Wave focused on his right hand.
"If I conjure a fireball using my right hand, it will be several times more potent than if I were to do it without Wave Focus. And a Level 3 Astral Wave Warrior would have enough strength to land a blow that could surpass the defenses of someone at Level 5!"
Silence reigned in the auditorium as the cadets heard Wink's words. They could not help but wonder how powerful could mastering Wave Focus could make you?
Of course, in that state, the rest of their body was defenseless, but did not using traps and ambushes solve that? As long as they land one blow, it would be game over for the enemy.
"That was Wave Focus. There is no difference between the speed of training of Astral and Essence Wave Cultivators regarding this art. It all depends on your individual talent and hard work. Now I will explain the last of the Four Basic Wave Arts, Wave Transmutation."
