Qi Fengtian didn't say anything anymore, and came to the pile of spiritual weapons to see what was suitable for her. In fact, if you think about it carefully, she really doesn't know what kind of spiritual weapon to use. Qi Fengtian looked at the pile of swords, rods, hammers, knives, bows and arrows and other spiritual weapons!

"Sister, what's wrong with you?" Dudu looked at Qi Fengtian's frowning brows, a little puzzled! Could it be that my sister is not happy to see so many spiritual weapons?

"I'm thinking, what kind of spiritual weapon should I use! I don't seem to have anything to do with it! Qi Fengtian said that she was very helpless, she used things that could be used as weapons in her previous life: kitchen knives, fruit knives, hammers, and guns, the first three things don't need to be thought about, they are indispensable in life, as for guns, this is the only thing she uses to be handy, but unfortunately this world does not have them. I've only seen swords and the like on TV.

"This is easy to do, I'll find it!" Dudu swallowed the last piece of chicken in his mouth and found it in the pile of spiritual weapons! It turned out that because of this, he thought his sister was unhappy!

"Found it!" Dudu held a piece of broken iron-like things, walked on his calves, and ran towards Qi Fengtian!

"Dudu, are you sure this is a spirit weapon? And not a piece of broken iron? Qi Fengtian took the broken iron in Dudu's hand suspiciously, looking left and right, it didn't look like a spiritual weapon, but like a piece of broken iron that had not been exercised.

At this moment, the broken iron struggled in Qi Fengtian's hand! Qi Fengtian was a little strange, and before she could let go, her hand was cut open by the broken iron. The blood stuck to the piece of iron was absorbed, and Qi Fengtian vaguely felt the connection with the piece of broken iron! Before she could say anything, the iron flew into her dantian and stopped steadily in the dantian.

"This guy has a very stubborn temper, he refused to contract with Sister Yunqing at the beginning, but now he didn't expect to be unexpectedly contracted by your sister!" Dudu finally recovered from the fact that Broken Iron was contracted by Qi Fengtian, and sighed!

"Huh! Dudu, what's that piece of broken iron? Qi Fengtian was also dumbfounded for a while. She didn't expect that she would contract a piece of broken iron by mistake.

The iron in Qi Fengtian's dantian trembled, as if to express Qi Fengtian's dissatisfaction with asking it to break the iron.

"She is a piece of divine iron that my sister got before, that is, it doesn't have much consciousness yet, and my sister wants to practice it into a spiritual weapon, but it was burned for a long time with the Tianyan Divine Fire, but it didn't melt, but it made it conscious. After many realizations, it can be turned into any weapon you want, and its level also increases with the master's level! At that time, I didn't let it contract with Sister Yunqing, but now I hit it by mistake, but I was contracted by you, sister, and now it is unhappy to be inexplicably contracted! Dudu said, gloating a little. He really didn't expect the iron block to be contracted, and he was looking for it just to try his luck.

"Ruyi! Will you call it Ruyi in the future? Qi Fengtian listened to Dudu's words, and suddenly felt that this name was very suitable for it. To be honest, it is indeed a very suitable spiritual weapon for her, as for the level, the stronger she becomes, the stronger it will become.

Ruyi trembled when she heard Qi Fengtian's words, and stayed quietly in the dantian.

"Dudu, is there any way to speed up your cultivation?" Qi Fengtian was very satisfied with Ruyi's reaction, and she suddenly thought that although her sister was a ninth-order junior soul master, it was still too low. Obviously, she forgot that she was only a fifth-order junior soul master. Although Grandpa's level is not low, he is already a Soul Sect, but his cultivation is endless, and the higher the level, the more difficult it is to cultivate, and it is best to speed up his cultivation.

"Alas! It's all to blame sister, you are too busy and don't understand the sky space clearly at all, otherwise you wouldn't have thought of asking me now! "Although Dudu doesn't want to hit Qi Fengtian, my sister really doesn't know much about the sky space.

"Ugh! Then let's take a look at the sky space first! "Don't mention it, Qi Fengtian really forgot that she didn't fully understand the Firmament Space, she was too eager to improve her strength.

Dudu began to take Qi Fengtian to understand the firmament space. After completely understanding the Empty Sky Space, Qi Fengtian was excited for a while, and then calmed down, the more the Sky Space went against the sky, the greater the responsibility she had to bear.

The firmament space is not very large, only two mountains and a plain, Dudu said that the firmament space will grow with her strength, as for how far it can go, he doesn't know. On a hill, some spirit trees were planted, and the trees were full of ripe spirit fruits. Qi Fengtian also picked a few to eat, which were particularly sweet and very delicious, Qi Fengtian's evaluation. On the other hill are some trees, and in the middle of the two hills there is a lake, not very large, only the size of a basketball court. There are two treehouses and one wooden house by the lake, all of which are natural tree houses made of growing trees; There were green leaves on the top of the treehouse, and when Qi Fengtian saw it, he liked it for a moment. According to Dudu, it was he who was so bored that he let the tree grow in the style of a house, and the tree house next to it was made by the egg, on the grounds that it wanted to make a home to sleep in. Next to the lake, there is also a one-acre large medicinal field, in which a lot of medicinal herbs grow, all of which were planted when Dudu was fine. Miraculously, there is a tree next to the medicine field, and under the tree there is a pool of spring water, which is the size of a cubic meter. The water comes out of the trees. Dudu said that the tree is called the Nirvana Tree, and the spring pool is an artifact made of 10,000-year-old cold jade, and only in this way can the Nirvana water flowing from the Nirvana tree be preserved.

"Nirvana is regarded as rebirth! Nirvana water can cleanse the muscles and marrow, reshape the meridians, remove impurities from the body, and increase the speed of cultivation. In other words, even if you are a wasted person, as long as you use Nirvana Water to succeed, you will become a genius! Dudu looked at Qi Fengtian's eyes that were getting brighter and brighter with his words, and laughed!

"This Nirvana water is really a good thing, but it's a pity that there are too few of them!" It's only one cubic meter, which is really a lot! Qi Fengtian looked at Nirvana Water with some pity.

"Sister, that's because you don't have enough strength! Because the space of the sky is limited, so the water of nirvana is also limited! Moreover, ten drops of Nirvana water are enough for one person! "It's not that Dudu wants to deliberately hit Qi Fengtian, it's a fact.

"Huh! All right! It's a matter of strength again! Be content! Qi Fengtian was not entangled, and began to think about when to use Nirvana Water.

"Sister, you'd better learn alchemy first, and then use Nirvana water!" Dudu knew what Qi Fengtian was thinking.

"Why?" Qi Fengtian looked at Dudu with some puzzlement.

"The whole process of using Nirvana Water is extremely painful, but you have to stay awake, and reshaping your muscles and veins will flow a lot of blood, and if you don't take the blood-replenishing pill in time, you are likely to bleed to death!" Although Nirvana water is good, it also carries great dangers, and if you are not careful, you may lose your life. That's why Dudu hopes that Qi Fengtian can learn alchemy first.

Qi Fengtian listened to Dudu's words, and did not rush to use the Nirvana Water, but instead carefully studied the alchemy methods and various elixir formulas in the Heaven Devouring Decision. After fully mastering the alchemy techniques and formulas, Qi Fengtian went out of the space and asked Qi Jingtian for a large number of medicinal materials from the first grade of the pill to the third grade of the pill, and by the way, she told Qi Jingtian that she was going to retreat for a period of time. Qi Jingtian didn't know what Qi Fengtian wanted medicinal materials to do, thinking that she just wanted a few plants to finish the trouble, but when she saw that Qi Fengtian had almost emptied the entire warehouse containing medicinal materials, she almost vomited blood in anger, but Qi Fengtian had already retreated, so she didn't know.

Qi Fengtian began to learn to refine the elixir. As for the flames, she wasn't worried at all, the Heavenly Flame Divine Fire that came with cultivating the Heaven Devouring Decision was enough for her. In the first few times, Qi Fengtian had been failing again and again because of his poor grasp of the heat. In the end, Qi Fengtian gave up alchemy, and instead learned to control the flame, and only continued to do alchemy after being able to control the flame 100%. This time, it was a success, six medium-grade pills. After that, he continued to refine, and after a few more times, he was already able to refine a perfect quality pill.

"Whew! It's finally done! "Half a year has passed in the firmament space, and half a month has passed in the outside world. Qi Fengtian basically cultivated in the morning and started alchemy in the afternoon, and she had already been able to refine the three perfect quality pills. The four-pin pill should also be fine. And the medicinal materials taken from Qi Jingtian were all used up. As for the strength, it has also reached the eighth order junior soul master.

Qi Fengtian freshened up, and accompanied Dudu for another day before leaving the firmament space.

"Sister, you're finally out of the customs!" After Qi Mutian learned that her sister was in retreat, she also retreated, and this time, she had already broken through the junior soul master to the intermediate soul master. She had been waiting outside Qi Fengtian's room for a day.

"Mu Tian has already reached the intermediate soul master! Yes, it's progressing fast! When Qi Fengtian saw his sister, he knew that her strength had taken another step, and he was happy for her. At least while she was in retreat, my sister wasn't idle.
