Before the library closed, Feng Xiaoyou finally looked through all the books on the fourth floor, and also had a preliminary understanding of the exercises in the foundation building period, and planned to go back and slowly start to integrate.

The voice of the disciple at the gate came in, and the three of them put down the books in their hands at the same time, got up and walked towards the staircase.

"Ten sisters, but you've finished reading them all?" Feng Tianshu asked casually.

"Well, I'm done!" Kazeshino nodded.

"I really envy the tenth sister, she can read so many exercises at once!" Feng Shihua said a little stupidly, she only finished reading three books in one day.

"Even if you finish reading it, you won't need it! It's not necessarily about reading a book as much as possible, it's important to make something in the book your own. The corners of Feng Xiaoyou's mouth curved up slightly, and he said softly.

"Well, although I know you're comforting me, I do feel a little better when I hear you say that!" Feng Shihua nodded slightly, his tone became light and lively, and he was obviously in a good mood.

The three of them walked out of the gate of the library building, because of the different roads, Feng Xiaoyou turned around and said goodbye to the two, "Third sister, seventh brother, I will go back first, see you tomorrow 'day'!" ”

"Okay, see you tomorrow!" The two of them spoke at the same time, and then stood in place, waiting for Feng Xiaoyu to leave first.

Feng Xiaoyou returned to her residence, and when she saw that Feng Songtao was not there, she went back to the room directly, arranged the enchantment, and prepared to fuse all the Xuan-level high-grade exercises she had seen today, she sat cross-legged on the couch and began to breathe, preparing to adjust the state to the best first, and then fuse. But what she didn't expect was that she tried many times but failed to find the point of fusion. She had to give up the idea of fusing all the exercises, choose a book of exercises, and try to merge the nine of them into one, but she still didn't succeed.

Feng Xiaoyou had no choice but to put down the fusion for the time being, and began to practice to adjust the state, and when the state was adjusted to the best again, Feng Xiaoyou chose a book suitable for cultivating to the upper grade of the Xuan level during the Qi training period from the book he read today, this is a metallic attack technique, called "Iron Bone Fist", this set of boxing methods is divided into seven styles, and the power is enhanced one by one from the first style to the seventh style. Feng Xiaoyou repeatedly deduced the seven-style technique in her heart, and when she deduced it to the sixth time, she finally found the point of fusion, and hurriedly raised her hands to pinch the magic technique, and a golden giant fist appeared out of thin air and struck towards the enchantment not far away, and the enchantment formed by the medium-grade magic weapon shook, and finally calmed down.

Feng Xiaoyou was very satisfied with the power caused by this move, and the corners of her mouth couldn't help but smile, but she was not in a hurry to continue to fuse, she had already guessed the reason why she couldn't fuse before, every time she fused a move, she needed to deduce all the moves over and over again in the sea of knowledge, until all the moves were fully comprehended, she would find the point of fusion, but what she wanted to fuse before was the exercises that could be used during the foundation building period, although she was able to play the trick over and over again in the sea of knowledge, but she couldn't fully comprehend the mystery, Naturally, it is not possible to integrate.

There are only five exercises suitable for use in the four-layer Qi training period, which means that there are only five exercises that Feng Xiaoyou can fuse, and she has discovered through the fusion just now that the power of this Xuan-level high-grade exercise is incomparable to the exercises of the lower three layers, so she decided to fuse the five exercises separately first, and then fuse them into one move, so that when fighting against people, she can also take out a single move to use. As for the moves that had been fused before, she also planned to sort them out and fuse them into three forms again, so that her fusion technique would still remain at the nine forms.
