Wood and fire are more profound and are the supreme mysteries. It''s too difficult to master them.


    However, Luo Zheng is not in a hurry. Everything needs to be understood slowly. Once it is natural, he can ascend to the sky step by step!


    Luo Zheng kept running the Tongtian sword array and didn''t waste any time trying to figure out the mystery of the law of lightning all the time.


    Suddenly, Luo Zheng felt that a powerful force was injected into his body.


    "OK, it''s finally finished!"


    Tongtian sword array finally refined the three demon pills. All impurities and alien blood energy were refined.


    Only the last pure dragon blood was left and poured into his body.


    Kaka, Kaka


    His body made a sound, and tough scales grew out of his skin and flesh.


    However, for a moment, on Luo Zheng''s forearm, thirteen egg sized scales were born, glittering and translucent, emitting a mysterious and powerful luster!


    "Dragon scale, real dragon scale!"


    Luo Zheng didn''t expect that dragon scales grew on his body.


    Just now he could clearly feel that his strength increased a lot with each scale.


    Moreover, the long dragon scale is a kind of dragon blood in the body, which changes and reflects from quantity to quality.


    "Hahaha, what a great power. The strength of the flesh has reached an unprecedented level. I didn''t enter the realm of cultivation, but my strength has doubled with the increase of the strength of the flesh!"


    Luo Zheng was overjoyed. It can even be said that his strength has not only doubled.


    Because, after a period of continuous speculation, he has gradually integrated the super electric crack light fist and the law of lightning into fencing.


    The improvement of swordsmanship is bound to increase its strength, which is beyond doubt!


    Boom!


    At this time, he suddenly opened his eyes, and a great force immediately came in from outside the prohibition.


    This muscle strength seems to be directly transmitted from outside the flower picking Buddha field, through time, space, and even the field is unstoppable!


    Luo Zheng moved and immediately stepped out of the prohibition and out of the quiet hall.


    He knew that the plan could not keep up with the changes. It was likely that there were changes outside. There was no time for him to slowly improve his accomplishments.


    Fortunately, this time his strength has been improved.


    "Luo Zhan, it seems that the castle ruins outside are about to open. Let''s go out!"


    The figure of the flower picking Buddha also appeared, and there was a faint golden light on him. During this period, his accomplishments seemed to have improved.


    As soon as he finished speaking, the flower picking Buddha waved his palm, which had closed the field, and their bodies appeared.


    However, no one noticed them at this moment.


    I saw everyone flying towards the castle, the huge city gate has been opened, and everyone is scrambling!


    Although Luo Zheng and Nianhua Buddha reacted very quickly, at this moment, half of the people rushed into the castle.


    During Luo Zheng''s closed door practice, many martial artists kept coming.


    There were only a few hundred people, but now there are more than a thousand!


    "Buddha, let''s go in and have a look."


    Luo Zheng suggested.


    This kind of remains preserved from the ancient times is a huge treasure for martial artists, and no one will let go.


    Although this huge castle is made of soul devouring magic stone, it is very dangerous.


    But cultivating martial arts is always dangerous. It''s worth taking the risk when encountering such ancient relics!


    "Go!"


    They said to go, and they used the birth method.


    go by like the wind!


    They immediately surpassed many masters who rushed to the castle, and their body shape shot into them instantly.


    When entering the castle, Luo Zheng''s first impression was that it was cold, wet and dark, which made people feel cold and dangerous.


    Inside the castle, there are countless dense passages. These passages are extremely wide. I don''t know where they lead, and the divine consciousness can''t explore to the end.


    In fact, after entering the castle, everyone found that the five senses and six senses were restricted.


    The extended distance of divine consciousness is only one tenth of the original.


    "The castle seems to have arranged an array. Even the main space of the sword is restricted, but fortunately, it is only half suppressed, which is much better than divine knowledge!"


    Luo Zheng''s heart moved and suddenly stretched out his hand to catch the void.


    He caught a black gas that didn''t know when it was lurking in the dark!


    This black gas, silent, invisible and intangible, seems to be completely integrated with the whole castle.


    Roar!


    The black gas was caught by Luo Zheng and roared into a big mouth full of fangs. Instead, it wanted to devour Luo Zheng''s arm.


    behave in a vicious and unrestrained way!


    Luo Zheng smiled coldly, and the whole arm burst out the power of lightning. The purple light flickered. At once, the big black mouth burst open and turned into white smoke!


    "It''s a demon soul, and it''s only a very weak form. It seems that you must be careful!"


    Luo Zheng looked dignified.
