Before Su Chen, the strongest move was Lei long. He released it twice a day to make money.


    However, after obtaining the flame spirit root, Su Chen''s strongest move should be replaced by the divine refining fire. The power of the divine refining fire is so strong that once released, even Su Chen may be unable to resist.


    But after going to shengtianzong, the terrible fire of divine refining had to be sealed, which was more embarrassing.


    Most of the skills searched from the seven star sword pavilion are Kendo skills. For Su Chen, there is no practical use value except returning them to skill points. There are only a few fire skills, which are not on the table.


    It would be more practical if we could get an imperial fire skill before arriving at shengtianzong.


    Knowing Su Chen''s request, the black phoenix thought for a moment and said, "master, you can talk to my eighth sister. She has a wide range of contacts and knows many experts. Maybe there will be some ways."


    "That''s the only way."


    At night, Su Chen knocked on the door of the purple Phoenix.


    After waiting for a while, the purple Phoenix opened the door lazily. She was only wearing a thin gauze skirt, leaning on the door frame and said, "little brother, it''s not appropriate to knock on a woman''s door in the evening."


    "Er... I''ll come back tomorrow."


    Su Chen was about to leave, but the purple Phoenix grabbed her wrist and dragged her into the room.


    Su Chen stumbled and almost didn''t fall on the purple Phoenix. Fortunately, he reflected, quickly stabilized his body and walked around the purple Phoenix.


    On purpose!


    Su Chen was helpless and wanted to pit an honest man like me. There was no door.


    The purple Phoenix giggled and didn''t say much. She invited Su Chen to come in and sit down.


    The warm sea breeze blew in through the pager. The purple Phoenix''s gauze skirt swayed with the wind, and her white thighs loomed. She twisted the snake''s waist and sat down, stretching the graceful curve of her body.


    But Su Chen was also a rule. She didn''t look at her at all.


    After a while, the purple Phoenix seemed to think it was boring and didn''t bother to tease Su Chen. He asked, "what does your little brother want?"


    "Is there an imperial fire skill? I can exchange ten bottles of Phoenix blood."


    The imperial level skill is still expensive. Of course, according to the real value, Su Chen''s Phoenix blood is the real priceless treasure for the Phoenix family.


    But after all, Su Chen is asking for purple Phoenix, and it should take the initiative to raise the price.


    Anyway, he is vigorous. Ten bottles of blood are just drizzle.


    The purple Phoenix giggled, "if it had been before, I would have promised without hesitation, but..."


    "What do you say?"


    "To tell the truth, I have refined a lot of holy Phoenix''s blood before, and the blood strength has been greatly improved. If I continue to refine holy Phoenix''s blood, the effect is much worse than before."


    Su Chen frowned and said, "ten bottles are not enough, then twenty bottles."


    "Deal."


    Shit, this woman is so poisonous.


    However, as long as you can get the fire imperial level skill, it''s easy to say anything.


    The purple Phoenix opened the storage ring, searched for a moment, and handed a red warm jade to Su Chen.


    Su Chen got the first mock exam, and felt that this warm jade was very hot, which contained a strong flame smell.


    However, there are many cracks on the jade piece, and it is incomplete.


    "This is an ancient incomplete skill I got in a secret place. It''s called ''Jiuyang true formula''. I once practiced it for my seventh sister. Her Huofeng constitution is very consistent, but there are many fragments of this skill. How much you can understand depends on your nature."


    Er, after working for a long time, you get me a incomplete skill?


    However, Su Chen doesn''t have any opinion. After all, he has a system in hand, and the incomplete skill has no impact on him, and this incomplete skill is often powerful.


    Su Chen immediately released twenty bottles of blood and exchanged the Nine Yang true formula with purple Phoenix.


    After Meizizi''s farewell, Su Chen immediately returned to the room with warm jade and sat cross legged. Her mental power began to flow into warm jade and absorb the skill information recorded therein.


    "Ding, congratulations on the host''s understanding of the new skill ''Jiuyang true formula''."


    Er, it''s too fast. Su Chen hasn''t read it carefully yet.


    The talent brought by the flame spirit root is really powerful.


    Su Chen immediately entered the skill library interface and checked the introduction of the Nine Yang true formula.


    But this time, Su Chen was a little silly.


    Nine Yang Jue... It''s a divine skill!


    Divine level


    Surprised my grandpa!


    Su Chen didn''t expect that the Nine Yang formula would be a divine skill. It''s too cheap.


    "Twenty bottles of blood in exchange for a divine level skill, making a lot of money!"


    "Nine Yang true formula: the divine level skill was created by the ancient fire demon true monarch by integrating the fire system skill theory of all ethnic groups. It is suitable for all ethnic groups to practice. However, due to the high requirements for practicing the Nine Yang true formula, no one can practice after the fire demon true monarch fell, resulting in the loss of the skill."


    Too demanding?


    Su Chen smiled. His flame spirit root was in his body. He was afraid that you were demanding?


    There are ten layers in the Nine Yang formula. Su Chen first looked at the consumption of skill point upgrade.


    At this look, Su Chen has a fool''s eye.


    Does the upgrade of divine level skill consume so little?


    It only needs 80000 skills to upgrade to level 1, 400000 to level 2, 2 million to level 3, 10 million to level 4 and 50 million to level 5


    Not only the initial skill point consumption is less than blink, but also the multiple of leapfrog doubling is only five times, which is completely different from the upgrade consumption of other skills.


    "System, what''s the reason?"


    System: "the number of skill points consumed by skill upgrading depends to some extent on the cultivation difficulty. If the host has a flame spirit root, the difficulty of cultivating fire skill will be greatly reduced, so the skill points spent on skill upgrading will also be reduced."


    "And this hidden setting?"


    Su Chen hasn''t found it before. Is it because his other talents are great and average, so this hidden setting is not displayed?


    Anyway, this is good news.


    Su Chen directly consumed 2.48 million skill points and pointed the Jiuyang true formula to the third level.


    He can''t wait to test the power of the Nine Yang formula.


    After the upgrade, Su Chen immediately felt that there seemed to be an extra meridian in his body.


    A fiery red, as if filled with hot meridians of magma.


    When the vitality moves to this meridian, it will be ignited immediately, produce variation, and the power seems to become more surging and irritable.


    What a grumpy spirit!


    Su Chen took a deep breath and immediately came to the bow deck and urged this special variant fire against the sky.


    In an instant, a raging flame erupted from Su Chen''s palm.


    The color of the flame is crimson.


    It is more intense and deep than the red of ordinary flame, just like thick blood.


    The crimson flame dances in the sky and can change into a different state of mind with Su Chen''s mind!


    Su Chen''s heart moved. The flame turned into a red giant sword and chopped fiercely towards the sea!
