In the training hall, scattered students walked around, heading to practice.

Compared to the raging storm outside, this place was much calmer, and most people didn't know that Longshou City was in turmoil at this time.

In the middle of the stairs, in a four-star second-order physique cultivation room, black squares flew horizontally, staggering impacts.

The star track sweated like rain in it, and the starstream sword in his hand trembled, precise and skillful, splitting each black square that struck.

The muscles of his right hand were tense, and the green tendons were bursting out, and there was a clearly visible tremor gradually increasing, which was caused by the recoil of the thunder frequency sword magic circuit.

Any attack will inevitably bring feedback, and the feedback of the Thunder Frequency Sword Technique is especially obvious and intense!

If you want to inflict a powerful lightning impact on the enemy, you have to bear the corresponding recoil, although Star Rail has not practiced this type of magic application before, but it has already been experienced in the duel with Manna and Kangwu, and it is not too difficult to cast it at this time.

As the star orbit became more familiar with the recoil, the impact frequency was constantly strengthened in order to feel how powerful the lightning frequency impact could be.

When the frequency oscillation reached about 400 times per second, he felt that he was almost at the limit, although he could go up further, but if it was not a frequency that could continue to fight, it would not be very meaningful.

"400......" Star Rail frowned slightly, this level was not much different from what he expected, but he was still slightly disappointed in his heart.

After all, the stronger he can bear, the higher his strength, and he urgently needs to improve himself now!

Judging from the records of the Book of Thunder, the Thunder Frequency Sword Technique can increase the impact frequency by about 150 times per second for each level of the four-star level, and between 300 and 450 is the excessive level of the four-star second order to the four-star third order, which means that he is now basically at the middle and upper level of the four-star second order.

It can also be inferred from this that Kang Wu should have just entered the fourth-star second order, but he still has a thunder beast body, and it is difficult to guarantee that the Witt family will not prepare him to deal with this game, so the star track can't be more careful.

As he pondered to himself, the black square offensive in the training ground began to slow down until it came to a complete stop, and Star Rail realized that the time had come.

Sweating profusely, he was a little unsatisfied, but it was already dusk, and he and Lisa had made an appointment to have dinner together, and it was inconvenient to stay longer.

He looked at the Starstream Sword, and was quite satisfied with the circuit design this time, with the cooperation of high-quality liquid silver and the core of the Thunder Bird, the energy efficiency of the magic guide reached 60% A-level, which was already slightly beyond his expectations.

After all, time is limited, and his understanding of the lightning frequency oscillation circuit is not deep enough, and he will optimize it when he has time, and he may be able to sprint towards the S-level magic guide energy efficiency.

As for the other magic weapons, he decided to remake them later, after all, the Flash Wolf King's leather has limited strength, and it can no longer meet his needs, and it is too time-consuming to find materials again, and he is now more eager to unlock the pass card and go to the seventh layer to have a look.

The situation in Dragonhead City was getting more and more serious, and he was worried that once there was a riot, there would no longer be this golden opportunity.

Thinking about his next plan, Star Trail left the training ground and headed straight for the library attic.

It was getting late, and the night overshadowed the dark clouds, pulling the dragon head city into the night.

The riots in the city have gradually subsided, and the flying ships in the sky have begun to gradually decrease, and Rheinfel took advantage of the weakening of the vigilance to sneak back to the Dragon Song King Academy with an understatement by taking advantage of the loopholes in the core circle.

He walked slowly to the training ground, stood in the doorway and glanced around, his eyes falling on a loop recording room.

There, it's a place to rent a star track!

Rheinfel raised his eyebrows lightly and came to the green-robed old man, the green-robed old man glanced at him, his eyes closed slightly, "It's you again?"

"The seniors have a good memory. Rheinfel smiled leisurely, "May I ask, what is the room for over there?"

Rheinfel is pointing to the loop recording room of the Star Track!

The green-robed old man glanced at it, his brows furrowed slightly, "That's the loop recording room." ”

Rheinfel suddenly pointed to the recording room and said, "I want to rent that." ”

The green-robed old man frowned even deeper, "Why?"

"Do you need to give a reason for the loan?" said Rheinfelch.

"You don't need to give a reason for renting, but ......" the green-robed old man narrowed his eyes, "The burning room is randomly assigned, and few people specifically ask to rent a certain one, and it's still that one!"

"Oh?" said Rheinfelden, "is there anything special about that one?"

"You're here for that kid too?" asked the green-robed old man.

Rheinfel's eyes lit up, and then he smiled: "You have discovered this, can I go and meet him?"

"It's not like you're going down the river at all. The green-robed old man snorted coldly: "You don't know that kid at all!"

Rheinfel didn't expect the old man in front of him to be so ruthless, and couldn't help laughing: "Whether I recognize him or not, I will go to see him, it won't violate the rules here, right?"

"He just left. The green-robed old man said coldly: "Also, that recording room is rented by him for a long time, and he can't rent it to you, so you can go." ”

"Left, where did you go?" asked Rheinfel.

"Do you think I'll know?" the green-robed old man looked at him coldly, "People outside the school, I advise you not to make more trouble, the current Longshou City is not peaceful, and that kid has an extraordinary background, you are careful to steal chickens and rice." ”

"Do I look like a villain?" Reinfel pretended to examine himself.

"I don't care what your role is, anyway, you can go. The green-robed old man waved away.

"Then I'd better rent a five-star ninth-order training ground. Rheinfel put down a pile of silver coins, "Three hours." ”

The green-robed old man frowned, as if he was hesitating.

"You have so many prohibitions here, and you're still afraid that I won't be able to make a living?" said Reinfel.

"Hmph!" the green-robed old man snorted coldly and gave a pass card to Rheinfel, "It's good that you know that there are prohibitions here, don't try to take advantage of it, I'll keep an eye on you." ”

"Understood. Rheinfel laughed loudly, picked up his pass and walked up the stairs.

The green-robed old man kept staring at Rheinfel until he entered the training room, then frowned and withdrew his gaze.

"Another unfathomable fellow, how many people is that kid going to provoke?!" the green-robed old man muttered to himself, but when he saw Rheinfel enter the training room, he was still a little relieved.

He knew very well that this was the core of the Dragon Head City Great Array, and his protective ability was second only to the palace, and he was not worried about what waves that young man could make.

This idea is naturally no problem for ordinary people, but he doesn't know that the person who entered that room is the only person in this world who has reached the peak of magic circuit cracking ability and personal strength.

The core of the current Dragon Head City Protector Array is nothing but nothing to him!
