Chapter 117 - 117

"Quickly open this black-covered book. The cover was changed later, and the pages inside are made of specially processed parchment. I don't know how many years it's been, and although the edges of the pages are a bit worn, the text inside is intact. But this book has no name, but upon careful examination of the font, it seems to be the work of a woman. After a rough look, I found that the techniques on it are not the martial arts previously practiced by Xuan Yuan Yuan. Obviously, Xuan Yuan Yuan doesn't recognize the text on it. Nowadays, in order for humans to communicate, language and writing have long been unified. And the writing is also very concise. Chu Tian didn't examine it in detail; he simply put away the black-covered book and glanced at the headless Xuan Yuan Yuan. Then he cast an invisibility spell on himself and flew into the sky. He didn't go to the refueling station designated by Nota, but flew directly into the city. It was still the temporary base as before, strengthened with some defenses. Chu Tian began to carefully examine the black-covered book. This book is not complete. Chu Tian found that some of the pages of this book had obviously been torn out from the middle. As for the lower half, Chu Tian did not see it in Xuan Yuan Yuan's space ring. After all, just now Xuan Yuan Yuan didn't have anything on him, not even the black cloak, which was just a normal cloak with a shielding effect. After reading the half book, Chu Tian recorded all the contents of the book. Chu Tian now felt that this book was divided into ten layers in total. When he reached the sixth layer, the spiritual energy in his body would automatically circulate and absorb the surrounding spiritual energy. Moreover, practicing this martial art could also directly devour others' spiritual energy to strengthen oneself. However, this book only contained the martial techniques of the first and sixth layers. Chu Tian put the book away, crossed his legs, and began to practice according to the content of the book. After practicing for more than two hours, Chu Tian opened his eyes, but he looked worried as he stared at the half book in front of him. Because he had practiced for several hours and didn't feel any improvement. Thinking of this, Chu Tian took out the martial art manual again and found that his practice was not wrong, so he began to practice again. But at this moment, the system's voice suddenly rang out. The system update is complete, and Chu Tian quickly checked it. This time, a new feature was added: Talent Refinement. Chu Tian checked the Talent Refinement feature, placed the talents he needed to refine into the refinement slot, and then used the beast core for refinement. The highest level of talent that can be refined is nine, and a talent at the ninth level is comparable to a martial art. As long as there is enough spiritual energy, it can completely match the power of earth-shattering martial arts. Seeing this Talent Refinement feature, Chu Tian could only smile bitterly. Beast cores are not something that can be easily generated inside fierce beasts, and in the Federation, they are mainly used for research. They have not fully explored the true value of beast cores. Although beast cores can absorb the spiritual energy contained within them, the conversion rate is extremely low, making them almost useless. So even if someone gets a beast core, they usually just hand it over to the Federation for research. Some people don't even bother to pick them up. However, in the many years of research on beast cores in the Federation, one discovery has been made, and that is that beast cores have the ability to promote the advancement of fierce beasts but seem to have no effect on humans. Thinking of this, Chu Tian suddenly remembered Ning Wan. She was planning to find beast cores in the dead Griffin Beast. Now he felt that Ning Wan's identity seemed even more mysterious. After all, a human would not need beast cores, and they would not treat spiritual energy crystals like candy. Thinking of this, Chu Tian couldn't help but be curious about Ning Wan's identity. Although he was curious, he had no intention of meeting up with Nota and the others because he couldn't be sure if the Clinton family had sent only Xuan Yuan Yuan to chase him. After checking the content of the system upgrade, Chu Tian began to practice according to the content of the unnamed martial art manual again. I don't know how long he had been practicing, but Chu Tian finally felt a faint spiritual energy response in his dantian. After all, those who had not reached the A-level talent in martial arts needed to rely on their talent to activate the spiritual energy in their bodies to release their innate abilities. Only when the free spiritual energy in the body reaches a certain threshold can they condense spiritual energy by practicing martial arts. However, now all the talent martial arts taught in the major advanced combat academies in the Federation require reaching A-level before practicing. So there is also a requirement to reach A-level before practicing martial arts and magic. Chu Tian condensed a trace of spiritual energy, making him feel that the spiritual energy in his body seemed unusually active. He continued to operate the martial technique from the nameless ancient book. After a day and night, when the sun rose between the buildings, Chu Tian finally withdrew from his practice. He exhaled a white breath and extended his hands. A golden light gathered in his hands, forming a short sword about a foot long. This martial technique had a total of ten levels, and he had just reached the initial stage of the first level after a day and night of practice, barely reaching the stage of releasing spiritual energy and condensing it into a sword. But this also made Chu Tian very happy. At least now he was a person who possessed martial arts without reaching A-level. After all, when he saw the magic of Aya and the martial arts displayed by Ning Wan, he was very envious. Chu Tian took out a spiritual energy crystal and absorbed it while practicing the martial arts. Until the second morning, Chu Tian felt that he had reached the peak of the first level. After three consecutive failures in his attempt to break through to the second level, he finally withdrew from his practice. Although he wanted to break through to the second level, it seemed that he had been a bit too optimistic. After a simple cleanup, Chu Tian took out some food and had a meal before preparing to meet up with Nota and the others. However, just as he was about to do so, Chu Tian suddenly felt something approaching rapidly towards the building where he was located. He released his spiritual power and quickly saw a small two-person flying vehicle. The person in the flying vehicle turned out to be someone he knew. Cleysa and Caesar, the strongest guardian of the Third Human Base. The flying vehicle quickly arrived at the floor where Chu Tian was located and hovered in front of the broken window. The hatch opened, and Cleysa and Caesar stepped out of the flying vehicle. Cleysa was wearing a tight-fitting black combat suit that highlighted her curves and figure. Caesar, on the other hand, was wearing armor but did not carry her large sword and shield. Seeing Chu Tian, Cleysa smiled and said, "Impressive, I didn't expect you to be able to kill an S+ level talent warrior. Not bad!" "S+ level? Just a trash who relies on all sorts of drugs. At most, his combat power
