Regner was overjoyed, he didn't expect that Velles had come this time to teach him his unique knowledge. Although the power of this wave blade is mediocre, it is silent and unleashed, and it is better than a strange one.

And for an assassin, there is no need for super destructive power and great momentum. In the eyes of a good Assassin, the power is just right, and the most important thing is how to use the right amount of power in the right place.

For example, if a person wields a 300-pound hammer, but he doesn't hit the enemy for half a day, then no matter how much strength he has, it will be in vain. And if a person is holding a dagger of 300 grams, as long as he can accurately send the dagger into the heart or throat of the enemy, then this very small force can exert the greatest effect.

And Wellles's wave blade follows such a line of thought, his fighting skill is not particularly serious for the consumption of fighting energy, and even the physical strength consumed by one knife is less than half of the air slash.

But if it is about threat, how can the huge and clumsy air-breaking slash be compared to the silent and untraceable wave blade of Wellles? Such a physical strength saving combat method is just right for Regner, his speed, explosiveness and control are all first-class, but physical strength is an obvious shortcoming, in the case of Cordak alone, if this strong man is pure physical strength, I am afraid that one can top Regner three. Even Vera wasn't much weaker than Regner in terms of physical strength.

Therefore, Verles's Wave Blade can be said to be a very suitable fighting skill for Regner, and even for all the Assassins, this fighting skill is very useful. After all, the guys who are known for their physical strength have all gone to be warriors, and they can fight the enemy without any scruples, who is willing to use their physical strength to fight with others?

"Please teach me, teacher!" Regner said sincerely, if he can master this fighting technique of Vellais, it must be of great help to improve his strength, and in this way, the safety of their group going to the western continent will definitely be improved a lot.

Vellais nodded: "I have already demonstrated it just now, this time, I will slow down all my movements a little more, you pay attention, and ...... Don't accidentally get slashed by me. ”

"Yes. Regner nodded.

Verles took a few steps back, and the figure faded into the darkness.

"Stealth?" Regner thought to himself, the wave blade was silent and invisible, and he vaguely guessed that this fighting skill might be related to stealth, but now that he looked closely, he found that it was indeed unexpected.

Regner looked around vigilantly with the swallowing light, and Velles's wave blade was silent when it came, and if he didn't want to get hurt, he had to be vigilant.

It didn't take long for Velles's attack to float over, and when the wave blade was cast, it would cause the space to fluctuate faintly, and although it was night, Regnar still faintly observed it.

He dodged the attack with a flip on his side, then took a throwing knife from his thigh with his left hand and assumed a defensive posture again.

Virlais's spatial fluctuations struck again, and Regner dodged this time with a lightning shrinkage of his head, and then threw out the throwing knife in his hand as he crouched.

"Ding!" Vellais revealed, his left index and middle fingers holding Regner's throwing knife.

"Very well done. Verles nodded again in satisfaction.

"I just speculated that this move might also be melee combat, which is why I tentatively threw the throwing knife. Regner bowed slightly.

"You guessed it, it's a melee skill. Verles admitted.

"But...... Teacher, how did you attack in a stealthy state?" asked Regner.

Unlike the mage's stealth technique, which makes the mage's invisibility visible to the naked eye, the assassin's stealth uses the fighting spirit to simulate the surrounding environment for camouflage, making the person appear transparent. That's why the best stealth environment is in the dark, because pure black is the best way to simulate.

Because of the need for extremely high control of fighting spirit, the assassin did not dare to make any big moves in the stealth state, and there was no way to attack. Because any big action will break the fragile camouflage simulated by the fighting spirit. Therefore, Regner was very puzzled by how Verles was able to attack while stealth without breaking it.

"Let me start with your opinion. Vellais said with a smile.

Regner thought for a moment, and then he asked Garona in his thoughts, "Teacher, what do you think?"

"I have a clue, but I'd like to hear your opinion as well. Garona said that she was also curious about Regner's insight.

"There are only some speculations, and I'm not sure if that's true. Regner was a little hesitant, after all, he was facing two Sanctuary powerhouses, and if he was wrong about running the train with his mouth, it would be a bit embarrassing.

"Say, it's okay to be wrong, after all, this is Velles' unique skill, and it is very unrealistic to force you to see the key at a glance. Garona encouraged.

Regner thought for a moment, and then said to Wellles and Garona at the same time: "I think that this fighting skill may be related to the control of the fighting qi, although the power of your wave blade is not very powerful, but when it is launched, it is silent, and there is no way to do it without extremely accurate fighting qi control ability." And this should also be the key to this fighting skill can be launched in the stealth state. ”

"That's a good point. Garona and Vellais spoke in unison.

Welleis continued: "It's not easy to see that. Now it's up to you to give it a try, and attack while stealth, while trying to stay in the stealth state. ”

Regnar nodded, his enhanced stealth ability made it easy for him to blend into the dark environment, and in this dark night with only moonlight, even Willless's perception of his disciple became blurred.

A few seconds later, Regner's figure appeared not far from Villeres, and the moment he gathered his fighting spirit on his sword, his disguise was out of balance, and he was forced to get out of his stealth state.

Regner was stunned, and then helplessly found himself failing.

"Yes, it's enough to do this for the first time, it seems that you can master this fighting skill quickly, so you can try it again. Verles walked over with a smile, and then whispered a few words in Regner's ear.

Regner's eyes lit up, and he went into stealth again. A few seconds later, Regner swung his sword again to break the stealth, and a strange scene occurred. Regner's figure became blurred again after a few seconds of clarity, and he was faintly disappearing again, but Regner obviously didn't maintain it well, and finally he still showed his figure.

"Failed......" Regna said with some disappointment.

"Very successful!" Welleis nodded with satisfaction again: "Although you have my theoretical guidance, even I have to admire your comprehension ability, I did far worse than you when I tried it for the first time." ”

The teacher praised it. Regner bowed his head slightly.

"And so it was. Garona also sighed in her heart: "Although the secret of this fluctuating blade is a bit worthless to say, but this sneak again, not everyone can do it." If you don't have the help of enhanced stealth, it will probably take years or even decades to master this fighting skill. ”

Stealth again, this is what Verles whispered to Regner just now, and it is also the biggest trick to use the Wave Blade.

Vellais originally envisioned a way of fighting that could constantly attack the enemy while stealth, and the requirement of this idea was to maximize the control of the fighting spirit. However, after two years of hard training, Verles finally found out in despair that no matter how hard he tried, he could not maintain his stealth state while attacking.

For this reason, he thought hard for more than half a year, and finally came up with a way to sneak again. While the first stealth can't last forever, why can't you go back into stealth after the attack?

It has also been proven that it is much easier to stealth again than to maintain a stealth state permanently. At first, Verles couldn't go back into stealth after each attack, but after a few years of practice, he was able to sneak again within seconds of attacking, and after a few years of practice, he was able to stealth again within a second of each attack.

Gradually, he increased his stealth speed to the limit, so that his figure would no longer appear in the eyes of his enemies after each attack. Because he stealthily is so fast that the enemy can't even notice it!

So, it wasn't for nothing that Velles didn't appear when he cast the Wave Blade, he appeared, but no one saw it!

It turns out that this is the secret of the Wave Blade......

Verles told Regner some tips for re-entering the stealth line, and then he pulled out a thin notebook and a small bottle of potion from his bosom and handed them to Regner:

"I think you've absorbed almost all of that notebook that was given to you more than two years ago. These are some of my deeper insights, and if you take them, if you have time to study more, it should be of great benefit. Oh yes, and a detailed explanation of the Wave Blade technique is also available above. As for this potion, it can be regarded as a reward for you. I know that Kordak's werewolf blood will cause you a lot of inconvenience, and this potion was specially made by the alchemists in my guild, although it can't completely solve Kordak's learning problems, but it can guarantee that he won't become a werewolf in two years. ”

Regner solemnly took the notebook and potion, and then thanked him sincerely.

Welleis looked at his disciple, and then continued: "That book not only records some of my experiences, but also records some of my observations and opinions in the Western Continent in the past few years. And this is also related to the second thing I want to explain to you. ”
