The huge deck fell into an inexplicable silence.

Everyone's eyes were swept together and locked on the cabin door.

They were anxious to know what Qin Yu was preparing for the second phase of training.

Squeak!

The closed cabin door was pushed open in response.

Beibo, who was obviously thinner, appeared again in the pupils of everyone.

However, the eye-catching scene made their pupils contract suddenly.

"Teacher, isn't this the incomplete Hailou Stone handcuffs, how did you get it out?" Luffy asked first.

As soon as these words fell, everyone's nerves were pryed, and their eyes were locked on Qin Yu's body.

If they remember correctly, these sea floor stone handcuffs were still obtained on the Shampoo Islands not long ago.

"Yes, this is the sea floor stone." Qin Yu patted the dust on his body, Huo Ran stood up.

"It is also the second phase of training for your three demonic fruit abilities."

For those who use Hailou Stone to train the demon fruit ability, for outsiders, it is simply whimsical.

However, as the reincarnated Qin Yu, he remembered it clearly.

In the original book, Luffy and Kidd were detained in the Rabbit Bowl in the country of Hezhi, wearing handcuffs from Hailou Stone.

Still able to fight and compete with each other.

In the end, Kidd, who had been held for a long time, was able to get under the eyes of many people with the ability of artificial demon fruits after wearing Hailou stone handcuffs.

Slid out of the rabbit bowl.

This is enough to show that Hailou Stone has a restraining effect on the devil fruit ability.

However, this restraint can use its own strength to resist.

It is precisely because of this speculation that Qin Yu set this as the second phase of the training program.

"Teacher Laxus, can we still move with this thing on?" Smog's cheek muscles could not help twitching.

Faced with this problem, everyone present was obviously holding this idea, and looked at Qin Yu.

After all, in their cognition, Hailou Shi is the nemesis of the devil fruit ability.

"Oh, you are still too young." Qin Yugan laughed and directly picked a Hailou stone handcuff in Beibo's hand and caught him.

The violent scene made Smoger and others nervous.

However, in their eyes, Qin Yu, who is also a devil fruit ability, is not soft on the ground.

"Isn't it weird!" Qin Yu said with a playful smile: "In the consistent cognition, the devil fruit ability person will be restrained by Hailou Shi, but the restrained strength is only the devil fruit."

"Although, it also has an impact on the body, but to a certain extent, the strength of Hailou Stone for its own strength and the domineering three colors will be infinitely weakened."

Speaking of which, Qin Yu's five fingers on his right hand were slightly clenched, and the dark and ink-like domineering colors quickly covered the entire arm.

The footsteps took a sudden step, and the whole person disappeared out of thin air like a ghost.

Appeared again, and had come behind Sauron.

The violent scene shook everyone's nerves.

Do not!

It should be said that this has subverted their cognition.

In their cognition, once the devil fruit ability touched the sea floor stone, it was the fish on the cutting board.

"Are you surprised?" Qin Yu handed Hailou Shi to Luffy with a smile.

When he subconsciously took it, the whole person fell to the ground like a deflated balloon.

"No, I feel like I can't lift my body anymore. Sauron, please help me quickly." Luffy said feebly.

This is indeed a real Hailou stone!

If it were said that they had doubts about the handcuffs of Hailou Stone in Qin Yu's hands the moment before.

Then Luffy's attitude now undoubtedly broke the only trace of doubt in their hearts.

In this world, those who really have fruit ability can ignore the influence of Hailou Stone to a certain extent.

Of course, only Qin Yu knows that what he has is only the dragon-killing magic given by the system, not the phantom beast thunder dragon fruit.

Not to mention Hailou Shi, even this piece of sea can't play any role in him.

He did this only to make Smog and others more convincing in his training.

"Teacher Laxus, you mean that as long as we are adapted to the sea floor stone and restraint on the body, then that means our own strength has broken through the limits?" Smoog couldn't help asking.

"Once the teacher can do this, he can still fight under the restraint of Hailou Stone. Can he ask the general's position?"

The inexplicable urgency mixed with the hurried words.

As a member of the Navy, the general is their most important evaluation criterion.

"Teacher, am I able to become One Piece!" Luffy quickly and feebly came out.

Looking at the two ambitious guys, Qin Yubai glanced: "You really are generals and One Piece are street cabbages, can you get it by playing with your mouth?"

"However, if you can successfully pass this training, I think it will not be too far away from the goal."

"Next, I prepared five standard handcuffs with sea floor stone content. You start with 20%, and strive to fully adapt within a month."

"Got the teacher!"

Smog and Luffy echoed anxiously.

Qin Yu motioned to Bei Bo to distribute the Hailou stone handcuffs, then looked at Ai Yin from the side and said, "Have you not written down the key points yet?"

"In fact, these training methods, as long as you master the method of cutting the sea floor stone, it is easy to copy. The most important thing is that you are unique, students with strong potential and toughness."

Speaking of which, Qin Yu rubbed Ayin's head and said, "The road ahead is still very long, and you need to master it yourself."

"Ah?" Ai Yin suddenly awakened, and after closing the hand in her hand, there was a hint of strange color on Qiao's face: "Teacher, what you say makes people feel as if they will leave at any time. Suddenly leave us? "

In Ayn's eyes, it was a great honor to invite from the naval headquarters and the chief instructor of the new barracks.

It is the only one in the navy that, in a sense, can play a decisive role as the marshal position.

It can be said that no navy member can resist this temptation.

"Oh, this kind of thing is not what your little head can think about, let's try Hailuishi training with a purity of 20% first." Qin Yu smiled and backhanded, handcuffed a Hailou stone in Ai Yin's wrist.

The sudden scene made her feel an electric shock instantly.

Feeling powerless, the footsteps stumbled and fell directly into Qin Yu's arms.
