Now, the strength in his muscles is definitely dozens or even hundreds of times that of ten days ago.

    His original physical strength is not very strong, but he is also stronger than ordinary people. Now he feels that he can completely disappear even if he punches down a mountain. He is much stronger than before.

    This is the second layer of rebirth, skin refining. Whether people often say skin or muscle, they all belong to the scope of "skin".

    Skin is the soft tissue on the surface of the human body, including our skin and muscle layer.

    This may be different from many people''s understanding, but that''s what the "skin" in the art of rebirth means.

    Zou Yi already knows that the third layer of rebirth is bone refining, but there is no saying of muscle refining.

    Zou Yi now can''t say that he has completed the practice of skin refining, but he can''t continue. He needs to give his body a buffer adaptation period, and then continue to practice after his body is slowly used to the current physical strength.

    He should practice Jiuyang now. Leaving here is the most important and urgent thing at present.

    And his current body, if he practices Jiuyang Jue, I think it will be faster.

    The day when he and nameless left the dark abyss is closer.

    It just takes time and energy to practice any skill or spell. Even if Zou Yi is practicing Jiuyang Jue faster now, it will take a lot of time and energy to break through the second level.

    On the first floor, it took him a year to succeed. On the second floor, I''m afraid it won''t take a short time.

    Nameless continued to try her best to guide Zou Yi to practice Jiuyang Jue. Even if Zou Yi didn''t understand anything, he patiently explained it many times. He didn''t let go until Zou Yi completely understood it.

    With such a responsible master, even if Zou Yi wants to have problems in practice, it is impossible.

    More than half a year later, with Zou Yi''s unremitting practice, he finally became the second layer of rebirth.

    The second layer is perfect, that is, even the skin has reached the perfect state, you can smoothly break through to the third layer of bone refining, and you can begin to practice the third layer of bath fire rebirth.

    At this time, the mana in his body was more than twice as much as half a year ago, and his purity was higher.

    This is like wine. The more alcoholic the wine is, the easier it is to get drunk, that is, it is easier to achieve the purpose of drinking.

    Zou Yi''s body has been transformed many times in this half year. Now he is as strong as a bison. He feels he can knock out a mountain with one punch.

    He vaguely felt that he could destroy a building without any effort.

    He had no chance to fight, nor could he test how strong his body was. He just vaguely felt that compared with him before, he is a god like existence now.

    Zou Yi''s Nine Yang decision and rebirth almost made a breakthrough at the same time, which surprised nobody.

    Nameless was very satisfied with Zou Yi''s performance. After letting Zou Yi rest for a while, he said to Zou Yi, "it''s time for us to leave here, so from now on, I''ll teach you the necessary spell to leave here, the Illuminati."

    Zou Yi and nameless stayed together for more than a year. She was already very familiar with nameless''s character. She knew that nameless was very serious at this time. She absolutely couldn''t talk to him with a smile, so she said in a straight face: "please master teach disciple Guangshu."

    Nameless said: "lightness is a necessary spell to leave here. I learned it originally, but because I have immortal power in my body, when I cast lightness, it will cause changes in the dark abyss, making it more difficult for us to leave. So I tried many times and couldn''t get out of here. "

    Zou Yi said, "then let the disciples perform this light skill to illuminate the way forward for the master."

    Nameless said: "your main task is to use lightness to illuminate the road, so as not to be trapped somewhere after we go wrong. I will try my best to take you out of here and let us see the bright world outside. "

    Zou Yi said confidently, "then please teach me the art of light."

    Nameless smiled: "I''ve already taught you the light skill, but you don''t know what you''re practicing is the light skill."

    Zou Yi was stunned: "when did Shifu teach me the art of light?"

    Nameless said, "do you remember the basic spells I taught you when I first taught you Valley breaking?"

    Zou Yi suddenly said, "it turned out that master had begun to think about leaving here at that time. That''s great."

    Nameless said, "think back carefully all the basic spells I taught you, and then connect those basic spells according to the formula of lightness I taught you to see what changes will happen?"

    Zou Yi said, "I see. Please tell me how to connect those basic spells."

    Nameless haha smiled and said loudly, "follow me and do whatever I say..."

    The nameless laughter was very big, far away, and the sound moved everywhere. He knew that he was about to leave the dark abyss, and he couldn''t restrain his excitement.

    Zou Yi cast dozens of basic spells one by one according to the unknown formula. At last, a light suddenly lit up in front of him, and a light actually appeared between his hands.

    A light as bright as the sun, even the dark abyss can''t stop its dazzling light.

    Zou Yi, who has been in the dark and hasn''t seen any light, felt very dazzling and couldn''t help but close her eyes.

    After his eyes adapted to the light, when he opened his eyes, a bright circle with a radius of ten meters appeared in the dark abyss.

    This is a miracle, because Zou Yi didn''t know how many times she tried various spells before, but she couldn''t make any light appear in the dark abyss.

    The effect of Illuminati seems to be very good. It''s about another advanced spell.

    Everything in the aperture can be seen clearly. The ground is also dark, but on the black ground, there is a very eye-catching small white line.

    The white line in the dark is deliberately left to guide the road. Otherwise, how can it be white? Black and white are two absolutely opposite colors. When they are put together, they are the most eye-catching and attractive.

    The white line is a sign to guide the road, extending straight into the distance until the light disappears, like a place swallowed up by darkness.
