Lin Xuan was initially shocked when he saw the black gas suddenly appear, but he quickly calmed down. He had personally seen how terrifying the black gas was. As long as he touched it, he would be like a maggot in his bones, unable to shake it off. If he were to encounter the black gas alone, Lin Xuan would definitely turn around and run without saying a word. However, Ji Ruyue was right beside him, and she had the super purifying potion in her hands. This was the confidence that allowed him to face the black gas calmly! Lin Xuan took a deep breath and threw the super purifying potion directly at the black gas that pounced at him! Buzz! The potion fell to the ground and immediately formed a dense green gas, completely enveloping the black gas. What made Lin Xuan very happy was that the black gas actually let out traces of screams! In an instant, it condensed into a distorted and terrifying human face! In just ten seconds, the black gas, which was the size of a human brain, completely lost its offensive power. The color also changed from a horrifying dark black to a pure white color. Ji ruyue exclaimed softly, “This thing is indeed not bad. It actually has such a powerful purifying power.” Lin Xuan cast a high-level observation spell on the white gas after purification, but he helplessly found that its level was too high, so he couldn’t see the specific information. “Is this thing harmless?”He asked. Ji Ruyue took a step forward, covered her palm with spiritual energy, and touched it gently. After touching it for a short while, she revealed a happy expression. “It can be absorbed! It’s very pure energy!” Ji Ruyue reached out her hand and grabbed the white ball of gas. She took a deep breath and immediately felt relaxed and happy. Moreover, the spiritual energy that had been flowing out of her body was slowly increasing. “This energy is different from spiritual energy, but it is also of the same type of strange energy.” Ji Ruyue looked at Lin Xuan and handed him a portion of the white gas. “Try it.” Lin Xuan was pleasantly surprised. “Okay, thank you!” Ji Ruyue smiled generously. “After all, it was your Super… super purifying potion that took effect. I just added a lump of spiritual energy casually.” Lin Xuan took the white clump of spiritual energy and imitated ji ruyue to bring it to the tip of his nose. He took a deep sniff. Buzz! The surging energy immediately surged into his body. Lin Xuan immediately saw that his warrior level was actually increasing! In just a few short seconds, he had risen by a large margin, and was only one step away from level eight or level two. Lin Xuan simply put in a few million essences and conveniently pulled his level up to level eight or level two. “HMM? I felt that your aura seemed to have become stronger just now. Your Earthlings’strength seems to have increased by leaps and bounds. It doesn’t seem to be progressing step by step like ours.” Ji Ruyue keenly sensed the small changes that had occurred on Lin Xuan’s body. Lin Xuan scratched his head and explained his level to her. “Although it’s beyond my understanding, I can roughly understand it…”ji ruyue nodded. “How much spiritual energy can such a white ball of gas replenish?”Lin Xuan asked. Ji Ruyue completely absorbed the remaining white ball of gas before answering, “It has recovered about one-tenth of my spiritual energy. It’s not bad.” As the two of them were talking, black gas suddenly pounced over like a snake. Moreover, the black gas seemed to be very intelligent. It completely ignored ji Ruyue and pointed straight at Lin Xuan. It seemed to be able to sense who was the soft persimmon. Ji Ruyue noticed this scene and shook her head gently. “No wonder I rarely encounter the black gas when I enter this place. I’m afraid that the black gas would have avoided me long ago when it sensed me.” This time, Lin Xuan was eager to give it a try. “Senior, can you trap the black gas?” Ji Ruyue thought quickly and immediately guessed Lin Xuan’s thoughts. “I understand. You make the medicine as soon as possible. I’ll use the spiritual energy to trap the black gas.” Then, she clapped her hands, and in the blink of an eye, an invisible spiritual energy cage was formed, trapping the black gas inside. The black gas rushed left and right, unable to break out of the spiritual energy’s restraint no matter what. It was so angry that it suddenly formed a face with distorted facial features and roared silently at Ji Ruyue. Ten minutes later, Lin Xuan successfully made the second super-purifying medicine. Just like before, after throwing the super-purifying potion, he quickly purified it. As usual, Ji Ruyue gave him one-fifth of the white gas. “This thing is not much to me, but to you, one-fifth is almost bursting your body…” Ji Ruyue also specifically explained that she was not a greedy person. Since they had a good cooperation, she did not mind giving a part to Lin Xuan. However, before she could finish her words, the fifth of the white gas had been completely absorbed by Lin Xuan and became part of the warrior level. “The progress bar of level eight and level two has already increased by half… This leveling speed is even faster than riding a rocket.” Lin Xuan was overjoyed. Ji Ruyue tilted her head. She thought for a long time but could not understand why the white gas not only did not burst Lin Xuan, but was quickly absorbed instead. “Another black gas is coming!” Ji Ruyue sensed something and looked behind her. This time, there were even more black gas. There were three balls, but they were much smaller. “For some reason, this place attracted a large amount of black gas. It seems that you need to prepare more super-purifying drugs.” Ji Ruyue smiled. Lin Xuan nodded happily. “Don’t Worry!” At this time, Tian yucai walked out from her hiding place and tidied up her clothes with a flushed face. “Why… Are You So Happy?”Tian yucai looked suspicious. “I’m happy about something,”Lin Xuan coughed lightly. Tian yucai was even more confused. In the next two days, they did the same thing and purified more than thirty balls of black gas.
