Although the black king Python demon king cannot refine three sword Qi, these sword Qi are also difficult to pierce his body.


    The black king Python has reached the realm of demon king. It has lived for nearly 500 years. Its body is extremely tough and can''t be broken easily.


    Luo Zheng ignored it and showed no expression. He gave full play to his swordsmanship to the limit.


    At this time, the black king Python was restrained. Luo Zheng immediately targeted the other two demon kings, pierced them with three swords and killed them.


    After entering the yuan military territory, his control over vitality was more exquisite. Although the Xinyuan sword code had no breakthrough, its power was more terrible.


    "Xinyuan sword code!"


    Luo Zheng''s eyes are as bright as electricity. The three swords in front of him interweave a heavy sword net, which gives full play to all his strength to the limit!


    At this time, his sword speed is faster and his sword spirit is more sharp!


    Whoosh


    Countless sword Qi immediately stabbed in front of the other two demon kings. These sword Qi took the key and pierced their eyes.


    The two demon kings were born in the two demon families of golden winged eagle and Juli flying bear. Their strength and speed are unparalleled, but with their speed, they still can''t escape the attack of Xinyuan sword code, so they can only connect hard.


    Boom, boom!


    Both demon kings burst out powerful attacks, collided with the sword Qi and made a loud noise.


    Luo Zheng defended the three demon kings with swordsmanship, which caused a situation of equal strength!


    If this kind of thing is spread, no one can believe it.


    These three demon kings are extremely powerful in the demon family and at the same level. They are all heterogeneous demon families with talent, supernatural power and terrible strength.


    At this time, the three of them could not help Luo Zheng, which is really unimaginable.


    Even the three demon kings themselves felt it difficult to accept. They couldn''t believe it. When they went all out, they couldn''t help Luo Zheng!


    Luo Zheng kept forging swords, honing his sword skills, and constantly comprehending the mystery of Xinyuan sword code.


    Gradually, he felt the mystery of Xinyuan sword code.


    "Sure enough, when you get started, you start first. When you are young, you can see the sword. These can be achieved through the explosion of powerful Qi. When you are young, you can move the sword, but it is a sword beyond space."


    Luo Zheng constantly fights with the three demon kings, repeatedly displays Xinyuan sword code, and finally understands it.


    "If you want to cultivate Xinyuan sword Scripture to Dacheng state, the most important thing is to improve the power of sword Qi, that is, the quality of vitality! Dacheng state is that when your mind moves, the sword Qi immediately penetrates into the space and kills your opponent!"


    He immediately understood why no one in Nanhai sword school could cultivate Xinyuan sword code to Dacheng, because this sword skill needs high conditions to achieve Dacheng.


    Luo Zheng suspects that ordinary swordsmen, not to mention the yuan elephant realm, even the yuan Dan realm, may not be able to practice swordsmanship to great success.


    Because the sword Qi penetrates the void and reaches the point of heart beating sword, the quality of sword Qi is very strong, and it is difficult to achieve in Yuan Dan realm.


    "It seems that this sword skill is just suitable for me to practice. My vitality quality is much higher than that of the same level. Maybe I can penetrate the void when I enter the Yuanxiang realm!"


    Luo Zheng fought fiercely with the three demon kings, understood swordsmanship and improved swordsmanship!


    His sword became faster and faster. Although he could not reach the Dacheng state of heart sword, he also killed the three demon kings with scars all over.


    Although these sword wounds could not really shake the root of the three demon kings, they also made them extremely cold.


    In the face of their opponents whose accomplishments are far inferior to their own, they have fallen into a passive situation and are difficult to win!


    "Damn boy, his strength is so terrible and powerful!"


    "This Terran is so terrible that it''s a monster!"


    "Go on, if we go on like this, we will not only kill him, but also be taken advantage of by him!"


    The three demon kings were so frightened that they even gave birth to retreat.


    "Want to escape? It''s too late!"


    Luo Zheng saw the intention of the three demon kings and immediately moved in his heart. Heikan sword and lanli sword flew out. The big five element sword array immediately operated and the five color sword Qi multiplied.


    "Big five element sword array, kill!"


    The five color sword Qi immediately spread all over the world, condensed into three huge swords, and cut off towards the three demon kings.


    "What kind of skill is this? How can it be so terrible!"


    The three demon kings shouted, and their hearts were filled with deep panic. They felt the breath of death.


    The attack from Luo Zheng''s Xinyuan sword dictionary just made them have more skin injuries and could not really break their physical defense.


    But the power of the big five element sword array cooled their hearts.


    They immediately turned around and ran away. They tried their best to rush out of the big five element sword array!


    Shua Shua!


    However, the sword Qi attack was faster. The three sword Qi were immediately cut off, leaving deep visible bone scars on their bodies.


    The three demon kings did not resist at all and turned into a body. One python, one bear and one eagle were hurt and fled outward.
