The next day, the mountain tree-lined trails.

Issei stood alone on the training ground, and the other people stood together to observe the results of Issei's training.

"Then use Boostedgear, Issei." Lias commanded Issei.

Since coming up the mountain, Lias has been forbidden to use the artifact, as for the things that Issei used when he was trained by Naraku, Lias didn't know, but on the last day, she herself broke the convention, and Issei didn't know why, Naraku showed a smile of "sure enough".

"Let's let Kiba be Issei's opponent."

"Okay."

At Lias's order, Kiba stood opposite Ichisei, his hands clenching the wooden knife, his eyes extremely sharp.

"Ichisei, activate the artifact before starting the simulated battle, I want to think about it...... Fight starts again after two minutes. ”

"Yes!" Issei followed Lias's words and let the Red Dragon Emperor's cage hand appear in his left hand.

The "supercharging" of the Red Dragon Emperor's cage hand is not endless, and the body can't bear everything, even if the artifact has no limit, the user also has a limit.

Therefore, the Red Dragon Emperor's cage hand actually has two major weaknesses: the first is time - this is a trick, combined with the information provided by Asahir and the information he can see, it can be completely ignored in the state of being banned.

The second is the host, no one can hold the power of infinite units, and neither can gods, but thinking about it the other way, this is also a tactical means that can be used, but at this stage, it is not yet known to Issei.

After doubling twelve times in a row, Yicheng stopped the amplification of the artifact, the artifact has an advantage, the device moves at will, a thought to let it start, a thought to make it stop, stop increasing the strength, how long it can be used depends on the action during the period, the shorter the activity time, the more intense the activity, the shorter the time, Yicheng is not easy to grasp the relationship between the two.

“Explosion！” The voice prompt stops multiplying the force, and this design is quite user-friendly.

"Kiba."

"Yes, Minister."

"Okay, let's go." Lias was crisp and decisive.

Wow, Kiba picked up his sword and hurried, and suddenly disappeared in front of Issei's eyes.

The vertical knife slashes and shoots mercilessly.

Wow...... Boom!

"Huh?!" Lias, Junai, Kitten, and Aisha collectively let out an exclamation.

I saw Issei moving sideways with a flat step, as if he had calculated a trajectory, allowing the wooden knife to slash past his side, narrowly avoiding it.

"Hah!" Kiba squatted and leaned over.

"Boom!" This was the sound of two objects colliding, and Issei pressed down with the back of his left hand to resist Kiba's blow.

Unlike a direct slash with the help of gravity, as long as the lower pick is not the key point of the attack, it can be caught with half of its strength, in other words, the opponent can only exert half of its strength.

“！” Kiba misses one hit and jumps backwards to stretch the distance, and Knight's characteristic is speed, and Kiba makes the most of that.

"I can't imagine what you taught Yisei?" Rias couldn't hide her surprised gaze, and whispered to Naraku, who was staring at the field and muttering numbers.

“50、51…… 57, 58, 59, 60......" didn't pay attention to Lias, and it wasn't until he finished counting that Naraku began to squeak, "It's nothing, I just used him to dodging the attacks of flying props, and after his dodge ability became stronger, he was able to barely avoid Kiba-san's slashes." ”

"Flying props?"

"You should know that space teleportation alone is not lethal, so I have developed a lot of moves based on this ability, among which shooting flying props is one of my moves, although it has no effect on stronger enemies due to conditions, but it is just right for Issei."

"This ......"

"But this doesn't mean that he can avoid the opponent's attacks every time, it's one thing to get used to it, and it's another thing to be able to avoid them all, even if Yicheng is used to dodging flying props, but there is always a difference between melee combat and long-distance combat, and the speed of your [Knight] is not comparable to Yicheng, and it's not useless that your body movements can't keep up with nerve reflexes." Naraku directly said Issei's weakness, "And Issei is still tender, even if he has experience in dodging flying props, but with his ability to be up to sixty seconds, you see, he can't hold it now?" ”

Lias's gaze returned to the battle scene between Issei and Kiba, at this time Issei was no longer as swift as before, after the initial surprise, Kiba quickly adjusted, thinking that Issei's dodge was due to the result of watching his many battles, even so, the way of swordsmanship lies in being fast and accurate, even if he can figure out the trajectory of the move, it is difficult to parry.

"Boom!" A dull voice came.

Issei held his head in one hand and kicked out, and Kiba quickly dodged.

"Ichisei! Attack with mana! Once you've created a mana condensate, launch it in the form you can imagine! Lias called.

"Yes!" Yicheng concentrated his consciousness and magic power in the palm of his hand, and for some reason, Yicheng found that his attention was extremely easy and condensed into a line, and the heat came from the palm of his hand, and a condensed magic force the size of a grain of rice was formed.

"It's so small!"

"Launch it."

"Ahh The magic condensation came out of his hand, and the moment he got out of his hand, it became as big as a boulder, but unfortunately Kiba still flashed in style.

Just as Issei hung his head and was about to raise the white flag......

"Boom!"

Only one sound.

The magic condensation collided with the mountain, there was no explosion, there was no amazing action, it passed through the center, and opened a huge tunnel for the mountain for free, and you could directly see the scenery on the other side, and the style changed instantly, and a broad road was directly opened along the way.

"To be honest, even I was shocked." Regardless of the disbelief on his face for the time being, Lias was also surprised, "What a surprise you gave me today, Naraku-san. ”

"It's okay." Naraku said noncommittally.

"After the magic power is released, it can still be condensed and not dispersed, to be honest, this kind of attack can't be done if you don't have a certain degree of control over your artifact, in just a few days, Yicheng can actually improve so much."

"It's just a trick, Issei hasn't achieved this kind of control yet, since I've participated in the special training, then of course I have to get some results."

"Thank you so much!" Lias glanced at Naraku, and without waiting for Naraku to speak, she walked straight to Issei.

"How does it feel?"

"Uh...... The magic power has been pumped a lot...... "Issei is floating under his feet and is weak, but because his physical strength is a little better than the original book, it has not yet reached the point of losing his combat effectiveness.

"Of course, that blow just now has the level of a high-level demon."

"This ...... Is this really what I did? Issei was still incredulous.

"Have a little confidence in yourself, Issei!" Lias cheered for Issei.

"At most two times, you won't have the strength to fight again, and you can hold it yourself."

After saying a few words in the end, Naraku ignored the reactions of everyone behind him, and directly opened the interdimensional space and left the training ground.

"The artifact of spatial teleportation is really convenient! But this distance can still be teleported at will, and the artifact can be used at will, if it is really like Ichisei said that he is only seventeen years old, then Naraku, this man must not be underestimated. "But it seems that he really only approached us because of Issei, and it was only when he had something to do with Issei that he suddenly appeared." ”

"Does Lias think she's thinking too much?"

"I'm familiar with everything in the Koma King Academy.,Naraku didn't 'emerge with Yicheng until the second year'.,It's too much of a coincidence.,If it's obtained at the same time as Yicheng.,The speed of his familiarity is too fast.,This doesn't rule out the possibility that he's a genius.,And,A person who just got an artifact.,Can deal with our affairs so indifferently.。

"What's more important is the time when Naraku-san's appearance."

"When the fallen angel was planning something in the town, Naraku suddenly came into our sight, the fallen angel likes to win over the artifact holder, I can't guarantee that Naraku is not one of them, his mind and strength are extremely good, and even his artifact will not be as simple as it is said, Grigori should not let it go."

"The Minister's speculation."

"Ah...... I also know that there is not much evidence to back it up, but I am not afraid of 10,000, but I am afraid of what if, if I really wronged Naraku-san, I will naturally apologize. Lias laughed to herself, "But I might just be jealous." ”
