The higher his strength, the more he can find the depth of martial arts and feel the pressure. He knows that he is not qualified to be complacent.

    Liu Guanyu, ban Xingtian and Mu Lan are all geniuses and powerful.

    However, Luo Zheng knew that these people were not the strongest teenagers in the hundred battles Dynasty, and there were more amazing people who had no chance to contact.

    These people will only arouse his fighting voice, constantly strive to move forward and defeat talents and opponents!

    Until you reach the peak of martial arts!

    Enter the cultivation room and close the door.

    Luo Zheng spread out his palm and there was a folded paper in his hand. It suddenly appeared in his hand when he bowed to the old instructor.

    "It must be given by the old gentleman. I don''t know what it means?"

    When you open the paper, there is a pithy formula with a few hundred words, which is called hidden interest method.

    Under the formula, there are four words: do not pass it on.

    There is nothing else.

    "I don''t know what the instructor means? This formula is very simple, but it is extremely precious. It can control the breath and make people unable to recognize the accomplishments."

    Luo Zheng was puzzled and read the formula carefully. He didn''t find any problems. He just couldn''t figure out why the old instructor, who had never met, would give himself great benefits this day.

    Unable to figure out the clue, Luo Zheng simply tried to run according to the formula. Sure enough, the fluctuation of real Qi completely subsided and his breath converged. He could not see that he was a warrior in the blood quenching realm.

    "Good thing, this formula is used to hide strength, and the effect is excellent!"

    Luo Zheng thought excitedly, "no matter what, we must find an opportunity to thank the instructor in the future."

    After being happy for a while, Luo Zheng put the paper full of formulas into the heaven and earth gourd, and then took out the stone, black iron card and meteorite dragon iron obtained in the ancient tomb.

    Meteor dragon iron is the embryo material of zikun sword among Tongtian 81 swords.

    In the material chapter of Tongtian record refining device volume, meteorite dragon iron is one of the most rare refining device materials and the top Heaven material and earth treasure.

    Only in some ancient Jedi where people can''t reach, can we find them. Luo Zheng''s unexpected acquisition this time can be said to be bad luck.

    According to the refining instrument volume, the power of zikun sword is still above lanli sword, which is extremely amazing.

    "As long as zikun sword is condensed, it can be combined with lanli sword to lay Liangyi star killing array. The power of Tongtian sword array is really revealed. I don''t know what degree it will reach."

    Luo Zheng''s handsome face showed a look of expectation, and he was vaguely worried.

    The quality of meteorite dragon iron is far above the blue fire crystal. It is very difficult for the star stone fire source to refine it.

    After thinking for a while, Luo Zheng did not hesitate too much and offered the star stone fire source.

    Hoo!

    The Yellow gray flame is burning, tightly wrapping the black iron brand and refining it.

    ……

    "Alas!"

    A day later, Luo Zheng took back the star stone fire source and sighed long.

    This daytime star stone fire source consumed half, while the black iron brand only refined one tenth.

    "The quality of meteorite dragon iron is too high. Even if the star stone fire source is completely consumed, it can''t be completely refined. It seems that if you want to refine the purple Kun sword embryo, you need to find a more powerful fire source. Originally, I thought that the difficulty of refining Tongtian 81 sword lies in finding materials. It seems that this fire source is also a great problem."

    Luo Zheng murmured.

    The materials used by the spirit sword Tianzun to refine the Tongtian 81 sword in those days are all natural materials and earth treasures with high quality. Many materials are even far above the meteor dragon iron. If you want to refine the sword, you can''t do it without a high-grade fire source.

    "Starstone fire source is already a three-level fire source, but if you want to refine meteorite dragon iron, you need at least four-level fire sources."

    The fire source is extremely rare. After the king''s family of Qingyan city got the star stone fire source, it has been passed down from generation to generation for hundreds of years. It is regarded as the treasure of the town family, which shows its precious degree.

    It is unimaginably difficult to get a higher-level fire source than the star stone fire source.

    Luo Zheng''s mind turned quickly, thinking and calculating.

    "Like xiaoyueer''s cold lotus fire source, it should be able to refine meteorite dragon iron, but king Rong can get the cold lotus fire source. I''m afraid it took nine cattle and two tigers. King Rong is one of the three different kings of the hundred wars Dynasty. I can only do this with great power. I''m a small pawn. I have no power and no power. It''s too difficult to get the fire source of Lingxiang."

    Luo Zheng understood the importance of power better at this time.

    The more powerful the martial arts practitioners are, the more resources they need to improve their accomplishments. Alone, they need to spend a lot of time earning cultivation resources. The improvement of accomplishments is naturally much slower.

    This is also the advantage of relying on big families and big forces. Once the family attaches importance to it or becomes the hope star of the family, the resources of the whole family will be inclined to it. You can concentrate on cultivating with all your strength and become a natural one day.

    This is also the reason why the talents of rich families come out and emerge in a steady stream. The strong Yu Yue and the weak are always weak.

    The strength of the family determines the starting line of its children.

    Maybe at the beginning, there are not many pills needed, and the difference will not be very large, but with the improvement of cultivation, this gap will become more and more obvious.

    For example, Luo Zheng, after his cultivation reached the peak of blood quenching state at this time, the number of pills needed to break through the state of changing marrow is far from comparable in the state of forging membrane.

    Luo Zheng spent a total of 200 blood nourishing pills when he was promoted from the realm of forging membrane to the peak of forging membrane.

    If you want to break through the state of changing marrow, you need to refine blood like mercury!

    The so-called refining blood is like mercury, which improves the blood quality and density in the body to the extreme, making the blood coagulation like mercury slurry. The amount of pills required in this process is extremely terrible.

    General second rate families will feel hard to support two or three family children to quench their blood, but it is easy for first-class families.

    "Owning Tongtian sword array, I can refine pills hundreds of times faster than others. I''m afraid it''s dozens of times faster than Liu Guanyu''s amazing talent. Moreover, the medicine refined by Tongtian sword array has more pure energy, derived real Qi and greater power. However, I consume a lot more pills than others. If I want to refine blood like mercury, I may More than a thousand blood nourishing pills are needed. "

    Luo Zheng couldn''t help opening his mouth when he calculated the approximate figure. How terrible the figure is, and it''s still the most conservative estimate.

    If it was two months ago, I was afraid to think about it. According to the market price of thousands of blood nourishing pills, it would be at least 3 million taels of gold.

    Even in this blood refining assessment, Luo Zheng had a lot of harvest, plus the pills and gold in the heaven and earth gourd robbed by Zhao Feng, there was still two-thirds of the gap in the blood nourishing pill.

    Two million taels of gold is still missing!

    Luo Zheng couldn''t help smiling bitterly. Others were worried that the speed of refining pills was too slow, but he was worried that the speed of refining pills was too fast, and the pills were in short supply.

    Of course, cultivation can''t catch up with others.

    "Last time, old Jia of Tianfu Pavilion said that after the stabbing Tiger Blade auction, the remaining gold will be handed over to me except for the expenses required by the auction house."

    Luo Zheng thought, "if I didn''t get the means to refine tools, I was afraid that the pill needed for cultivation would be a great trouble. Now all this can be exchanged through refining tools."

    "By the way, the word power and money in the world can''t be separated. Although I don''t have the towering power of King Rong, I can refine weapons. As long as I have a lot of money, even refining weapons can exchange for fire sources, or news about fire sources!"

    An idea suddenly occurred to Luo Zheng.

    Ordinary tool refiners can only refine two pieces of magic tools in a month. Luo Zheng''s method of mental refining is an unparalleled tool refining method. The speed of refining tools is unmatched by other tool refiners. As long as there are appropriate materials, they can refine ten magic tools a month.

    "It''s nearly two months before the winter break. That is to say, I can''t leave the camp of the five beast army until at least two months later. The pill I have can only support my cultivation for three days at most. If I stay in the camp, I can''t get the refining materials, and my cultivation will not be successful. It seems that I have to find a way to leave the camp. Except for the season break Besides, the only way to leave the camp is to go out and perform experience tasks. "

    Soon, Luo Zheng thought of the way to leave the camp. He had a certain idea in his heart. He didn''t think about anything else. He took out the secret script of flying star step and studied it.

    Five days later, Luo Zheng opened the door of the cultivation room and went out.

    "Didn''t the old instructor say it was difficult to sense the power of the stars? Did he scare me?"

    Luo Zheng whispered in his mouth. He had heard that even those with high talent can feel the power of the stars in three months. Without talent, he can''t succeed in ten or eight years. He was still worried.

    I didn''t expect that I felt the power of the stars after only one day of cultivation. Although I didn''t cultivate the flying star step to what an amazing state these days, I was close to Xiaocheng.

    "It seems that my talent is too strong."

    Luo Zheng smiled at the corners of his mouth, summarized it, and came to Wang Nian''s residence.

    Isn''t this fat man working hard? Why did you relapse in a few days? At this time, you are sleeping without practice!

    Luo Zheng shook his head and finally woke up the fat man. He said that he was going to take some training tasks from the five beast army.

    Wang Nian was confused and sleepy. "To take the training task, you should at least reach the level of elite military soldiers."

    "Well, I know. Are you all right?"

    Luo Zheng looked at Wang Nian with some worry. The martial arts practitioners were energetic. They didn''t sleep for three days and nights and wouldn''t feel tired. It''s not normal for Wang Nian to look like this.

    "I''ve been trying to practice the formula of gluttonous swallowing heaven recently. These two days, my appetite suddenly increases and I''m sleepy when I''m full. I don''t know what''s going on."

    Wang Nian murmured.

    Luo Zheng, who dared not sue, ate a cow yesterday. It''s really strange!
