Regudu is preparing to build weapons for Du Wu. He said to Du Wu and the others: "You can practice around here, although the environment here is hot, it is very suitable for people who practice martial arts to cultivate, the rich fire attribute aura here has the effect of tempering true qi, you can cultivate here much faster than in other places." When everyone heard this, they all dispersed, looking for a suitable place to cultivate. I saw them standing, sitting, lying or lying, in a variety of strange postures. Among them, Reyriza's body is upright, with his left hand behind his back, his right hand stretched out to the sky, and his two fingers pointing to the sky, and his whole body is like a sharp sword piercing the sky. Ruyi is meditating cross-legged, looking at his nose and nose and asking his mouth and mouth, his hands are knotted into flower fingers, and his expression on his face seems to be smiling rather than smiling, which is very holy.

Du Wu didn't go to practice, she asked Regudu: "Uncle Re, don't you need a helper to build, I have also learned from my blacksmith master for a few years to build, I can give you a hand, I also want to learn from you the technique of building." ”

Re Gudu said: "Originally, I needed a helper, but your heart of the stars has an extremely high melting point, and you need to use the hottest part of this pure yang true fire to calcine, so you can, I don't know if you can withstand the temperature there?"

Du Wu asked, "Is this hottest place the center of the magma lake?"

Re Gudu said: "No, this pure yang true fire is the same as other flames, divided into outer flame, inner flame and flame heart, ordinary people think that the flame heart has the highest temperature, but in fact, the hottest is the outer flame, that is, the part that has just entered the flame." Take this place as an example, it is about ten zhang away from the center of the magma lake, which is the outer flame of pure yang true fire, and the temperature there is quite difficult for me to resist, and every time I go there to build, I will be greatly injured, and I need to recuperate for a month or two to recover. To build a normal weapon, you still have to be ten feet away from the outer flame, and I usually build it there, because there are no materials that need a hotter flame. But this heart of the stars is not successful, its melting point is extremely high, and it is only possible to burn it when it reaches the outer flame, and I am afraid that you will not be able to stand the high temperature there. ”

Du Wu smiled and said: "Uncle Re, I have something on my body that can withstand the high temperature here, I just feel a little hot now, and I haven't been able to resist it, and I can also stand the heat of the outer flame." ”

Re Gudu Daqi asked: "Oh, what is it that is so magical, this pure yang true fire is ranked among the seven treasures of Qiankun, and ordinary treasures are extremely difficult to resist." ”

Du Wu took out the Holy Water Spirit Bead from his arms and said, "Uncle Re, this is the Holy Water Spirit Bead, which happens to be one of the Seven Treasures of Qiankun. It shouldn't be a problem to resist the heat of pure yang true fire. ”

Regudu's jaw dropped in shock, and he said that this girl has too many treasures on her, and it is the chariot of phantom silver, and it is the heart of the stars, and now she actually took out a treasure in the seven treasures of Qiankun.

It took a long time for Regudu to come back to his senses and said: "With this treasure, the difficulty of building will be reduced a lot, I was still worried, but now it seems that the task can be easily completed." Wait a minute, you don't have to do it, you just need to take the holy water spirit bead to protect my heart and let me keep the spirit platform clear. ”

Du Wu hurriedly nodded in agreement, Re Gudu took Du Wu and walked along the stone platform to the center of the magma lake, Du Wu felt that with every step, the temperature would rise a little, and the holy water spirit bead would also emit more cold air to resist the high temperature. The two of them walked straight to the place ten zhang away from the center of the magma lake, which is the place where the outer flame is called by Regudu. The temperature was already unimaginably high, Du Wu stretched out a hand out of the range covered by the Holy Water Spirit Bead, and felt that his skin quickly became dry, as if he had been pricked by a needle. Hurriedly retracted his hand. Du Wu urged the innate true qi to stimulate the power of the Holy Water Spirit Bead, so that the cold qi emitted by the Holy Water Spirit Bead formed a protective cover, enveloping her and Re Gudu in it.
