After saying goodbye to Su Shu, Lin Tian didn''t hang out in Wu Fu, and soon returned to his residence.

    Soon after, night fell. When Lin Xi fell asleep, Lin Tian came to the top Pavilion of the hut and took out the Jiuqu essence pill from the brocade bag that Mu Qing gave him. The pill was red gold and faintly fragrant.

    "Start!"

    Lin Tian takes a deep breath and carefully puts the pill into his mouth.

    The pill melts at the entrance and flows into Lin Tian''s stomach like a gentle spring.

    Half a quarter of an hour later, Lin Tian felt that his body was hot, as if there was a fire in his body, and the burning sensation soon spread all over his body. His body gradually became hot, and his bare skin turned fiery red.

    "Right now!"

    Lin Tian knew that the pill had begun to take effect. He immediately started to run the four polar meridians, refining the pill aura that rushed into his body.

    "Hum!"

    Light light flowed on the surface of the body, making the dark Pavilion lit up a little.

    Gradually, Lin Tianxin was shocked. He felt as if there was an aura volcano in his body. The rich aura seemed to rush across his body. The terrible heat seemed to melt him completely.

    At this moment, Dan pill aura filled every corner of his body!

    "What a Jiuqu elixir! It''s a valuable treasure!"

    He said in his heart.

    His body became more and more hot. Lin Tian didn''t dare to be careless. He put his whole heart into the four pole classic to quickly guide the Dan pill aura into the flesh and blood, and refined the flesh and blood again and again with this pure aura.

    An hour later, there was a sudden shock in Lin Tian.

    At this moment, he reached the quadruple!

    At this time, he still had a lot of Dan pill aura in his body, wandering around like a dragon hunter.

    "Keep practicing!"

    The four pole Sutra continues to work, just like the essence of Jiuqu pill. Lin Tian doesn''t want to waste any of it.

    However, now it is different from before. This time, he is no longer simply guiding aura into flesh and blood, but using Zhenyuan as a guide to lead these auras into bones and muscles.

    Harden your muscles and bones!

    "It hurts!"

    In a flash, Lin Tian''s body trembled and he felt severe pain.

    There are nine levels of refining body: the first three levels of refining flesh and blood, the middle three levels of refining bones and muscles, and the last three levels of refining viscera. Now Lin Tian has reached the fourth level of refining body, and immediately begins to refine bones and muscles with Zhenyuan''s guiding spirit. However, refining bones and muscles is more difficult than refining flesh and blood, and the process of refining is several times more painful than refining flesh and blood.

    At this moment, Lin Tian only felt that a sharp blade was cutting his meridians, and a heavy hammer was beating his whole body. The kind of split body pain made him almost roar out, and the cold sweat dropped one by one.

    "Although the martial arts are very powerful, the process of practicing is just suffering!"

    Lin Tianyin scolds.

    Having said that, his cultivation did not stop, but became more serious.

    Zhenyuan guides the aura to refine the muscles and bones, making the muscles and bones tough and firm, and the strength of the warrior also increases greatly. Not only that, at this stage, a part of Zhenyuan will stay in the muscles and bones, forming a micro cycle with Zhenyuan in the flesh and blood, thus greatly enhancing the warrior''s Qi, blood and endurance.

    Lin Tian ran the four extreme Sutra over and over again. Although he was in great pain, he could bear it. Gradually, his skin became normal, no longer as red as before.

    Four hours later, the darkness dissipated and the dawn fell on the earth.

    Lin Tian opened his eyes, spit out a long breath of turbid gas, and then stood up.

    He clenched his fist and moved his body. He felt that the whole person was much more relaxed, his hearing became more acute, his sight became clearer, and his whole body seemed to have endless strength.

    "Refine the body five times!"

    Lin Tian was surprised.

    One night''s practice made him stride directly from the triple heaven to the quintuple heaven, which was a great progress. You know, from triple heaven to quintuple heaven, many people have to spend a year, but now, he just did it in one night, how can he not be surprised.

    At the same time, it also made Lin Tian realize the value of Jiuqu essence pill.

    "You can choose your martial arts skills!"

    After some excitement, Lin Tian thought of the selection of martial arts, his eyes suddenly lit up.

    He took out the notes, poured Zhenyuan into them, and began to contact Su Shu.
