Two crystal nuclei were placed in front of him, and Black Rock was completely dumbfounded. With a wooden expression, he looked at Zhou Peng with disbelief in his eyes. His mind seemed unable to turn around, and his voice trembled a little when he spoke. "Crystal nuclei, where... where did you get them?" There were two crystal nuclei, and one of them was from a sixth - level monster. The shock this brought him was so great that he could hardly believe it. At the beginning, their thirteen brothers chased and killed for half a month. Twelve of them died, and they still didn't kill the violent (King Kong ape). If Zhou Peng hadn't appeared, he surely wouldn't have survived. He had a deep understanding of the horror of the fifth - level monsters. How difficult it was to hunt and kill a fifth - level monster? Now, there was not only a fifth - level monster crystal nucleus but also a super powerful sixth - level monster crystal nucleus. How could he believe it? Zhou Peng's talent and potential were the best he had ever seen. It was not an exaggeration to evaluate him as a once - in - a - century genius. But he was only at the Gathering Spirit Realm, and he had just broken through. If a person at the Gathering Spirit Realm could kill a sixth - level monster, his dozen or so brothers wouldn't have died. Shocked and excited, his eyes were full of disbelief. Zhou Peng scratched his head and smiled, saying, "Good luck. I just happened to catch two monsters fighting to the death and took the opportunity like a fisherman." He said it very easily, but Black Rock was very shocked when he heard it. The battle between two high - level monsters was extremely terrifying, with the power of destroying the heaven and the earth raging. Zhou Peng said it casually, but in his heart, he was shocked. There was no such good thing in the world. No matter how good the luck was, without some strength, he would not be the opponent of a sixth - level monster. "Brother Black, this sixth - level crystal nucleus is a gift I give you." As he spoke, Zhou Peng handed the crystal nucleus to Black Rock. Black Rock was slightly shocked, and his hand subconsciously shrank back, saying, "The value of the sixth - level crystal nucleus exceeds that of the ordinary gold - grade cultivation method. Refining it can bring supreme benefits, and the cultivation level may even continuously break through. I dare not accept such a precious gift." "Brother, when I kept the crystal nucleus of the violent (King Kong ape) that day, I made up my mind to compensate you with a crystal nucleus. Please accept it, or I will feel indebted." Without swallowing the crystal nucleus of the violent (King Kong ape), Zhou Peng couldn't have killed the Blood - eyed Maned Lion at all, let alone obtained two crystal nuclei. During this period of getting along, he regarded Black Rock as his own brother in his heart. And Black Rock also regarded him as his own brother. Zhou Peng remembered all these things in his heart and had been looking for an opportunity to repay the kindness. Although he was not a good person, he was a person who would repay kindness. He was able to enter the Kunlun Mountains, and his breakthrough was so fast in the past six months, all because Black Rock had been helping him, helping him without complaint. For Black Rock, entering the Kunlun Mountains didn't help his cultivation much, but he sacrificed his own time to accompany Zhou Peng into the Kunlun Mountains, which was a great kindness to Zhou Peng. Not to mention compensating with a sixth - level crystal nucleus, even if Black Rock wanted both crystal nuclei, he would give them to him without hesitation. Furthermore, he could understand the feeling of hard cultivation without breakthrough. For Black Rock, this crystal nucleus was very important, related to his future cultivation path, and even more related to his path after joining the Liuyun Sect. Therefore, no matter what, Zhou Peng must make Black Rock accept the crystal nucleus. Looking at Zhou Peng's sincere eyes, Black Rock choked with sobs and was deeply moved. Crystal nuclei were very precious to anyone, but he gave them to himself without hesitation. He remembered this kindness in his heart. At present, Black Rock didn't hesitate anymore. He picked up the fifth - level monster crystal nucleus on the ground and said, "Thank you." Thank you. These two words were very heavy. Black Rock said it with deep feeling. He had been at the first level of the Tempered Gang Realm for a long time. He had been cultivating hard but couldn't make a breakthrough. At this time, the crystal nucleus was very important to him. But the crystal nucleus was also important to Zhou Peng. Zhou Peng's growth had exceeded his imagination. In time, he would surely shock the entire Tianyuan Continent and resound throughout the universe. Zhou Peng still wanted to argue and let Black Rock keep the sixth - level crystal nucleus, but Black Rock waved his hand to stop him from speaking. Finally, Zhou Peng didn't say anything more. "Hum, hum..." Maomao gently rubbed against Black Rock at the side and grinned, as if they were very close. "Brother, this is Maomao," Zhou Peng said with a smile. "Blood - eyed Maned Lion," Black Rock recognized it at a glance. Looking at Maomao's blood - red eyes, his heart was shocked. Then he looked at Zhou Peng and said, "This is a newly born cub, very rare. If fed well, it can become a powerful helper, and it is a very belligerent monster." "Why does it follow you? Its mother..." "Could one of them be the crystal nucleus of the Blood - eyed Maned Lion?" Black Rock was shocked secretly. Looking at Zhou Peng, his heart was greatly shaken. The Blood - eyed Maned Lion was not an ordinary monster. It was a monster that could release powerful cultivation methods, extremely belligerent. The Blood - eyed Maned Lion that could cultivate to the sixth level had experienced no less than a million battles. The cub of the Blood - eyed Maned Lion was very rare. The cub would be close to the first person it saw when it was born and regard him as its mother. This was the reason why Maomao ran to Zhou Peng and licked the blood on his boots when it was born. Zhou Peng smiled, which was regarded as (default). But seeing Black Rock's shocked expression, he still asked, "Is the cub of the Blood - eyed Maned Lion very rare?" "Very rare," Black Rock gently stroked Maomao's short mane. Maomao narrowed its eyes comfortably, looking extremely enjoying. Black Rock smiled and said, "Taming cubs is very difficult. You should be prepared." Taming masters were very rare on the Tianyuan Continent. Generally, only the huge cultivation sects would have special taming masters. The monsters tamed by them could not only be used as mounts but also for fighting. Some cubs grew up and their fighting capacity was very terrifying. However, it was very difficult to tame fighting - type cubs. On the Tianyuan Continent, taming masters generally tamed mounts that could travel thousands of miles a day, and very few tamed fighting - type cubs. Of course, Zhou Peng didn't know these at all. At the beginning, he agreed to the Blood - eyed Maned Lion out of soft - heartedness. Who knew that he had triggered the pet system task? He had no choice but to accept it. Now, hearing Black Rock say that it was very difficult to tame fighting - type cubs, he regretted again. Maomao seemed to understand the conversation between them. It lowered its head and walked to Zhou Peng's side, looking up at Zhou Peng, showing a pitiful expression as if it was saying, "Don't abandon me..." "Don't worry, I won't abandon you," Zhou Peng smiled sinisterly and thought in his heart, "I still need you to test the pills." Looking at Zhou Peng's sinister smile, Maomao slightly stepped back, shivering all over, and looking at Zhou Peng pitifully. This made Zhou Peng and Black Rock laugh. --- Time flies like running water, and the days pass quietly. Unconsciously, it had been a year since they entered the Kunlun Mountains. The experience in this year had made Zhou Peng much stronger. From the original fourth level of the Agile Realm to the current third level of the Gathering Spirit Realm, this speed could make the entire Tianyuan Continent tremble and make countless peerless geniuses ashamed. Black Rock envied Zhou Peng from time to time, feeling that he didn't need to cultivate at all to break through, without any bottlenecks. He just kept hunting monsters and then breaking through, just like a monster. There had been no one on the Tianyuan Continent who could break through by hunting monsters, except Zhou Peng. At the entrance of the mountain cave, Black Rock looked into the distance and stared for a long time, saying, "I'm leaving. Take good care of yourself." "Yes, I will," Zhou Peng stood aside and nodded. Black Rock was about to leave. The distance from the Kunlun Mountains to the Liuyun Sect was no less than ten thousand miles. Even Black Rock at the second level of the Tempered Gang Realm would need several months to arrive. It just happened to catch up with the time when the mountain gate was opened in spring and the sect was recruiting disciples. They were silent for a while. Then Black Rock took a serious look at Zhou Peng, smiled, and jumped down...
