Wei Tian followed closely and saw that Gu Gu was already happily tinkering with his Gu Cauldron. He was also particularly happy. Originally, Wei Tian wanted to wait until he came out of the dimensional realm before learning Gu skills from Gu Gu. Yes, but after seeing Gu Gu's longing eyes every day, Wei Tian also felt a little guilty in his heart. After getting along with Gu Gu for such a long time, Wei Tian already felt a sense of intimacy towards Gu Gu. This feeling was like Like family members. "Master, what do I need to do?" Wei Tian asked when he saw the busy Gu Gu. "Take out your Gu Cauldron first." Gu Gu said. Wei Tian directly took out the golden Gu Cauldron he got in Death Valley from his storage ring. "Master, how is my Gu Cauldron? What level is it?" Wei Tian looked at the golden Gu Cauldron in his hand with curiosity in his heart. "This Gu Cauldron of yours is not an ordinary Gu Cauldron. You must protect it well. As for what level it is, I won't tell you for now." Gu Gu replied. "Then what kind of Gu do you want to teach me to refine?" Wei Tian asked. "Let's start with the lowest grade Gu Pill. First, we should refine a powerful Gu Pill that can increase physical strength." Gu Gu replied. "This kind of elixir must not be particularly expensive, right?" Wei Tian said with a hint of weirdness in his tone. "You kid, you are still thinking about these things. Although the price of powerful Gu pills is low, if you refine hundreds of them every day, your gold coins will be inexhaustible, and if they are used by other big If the family likes you, then your status is no lower than any alchemist." Gu Gu stared at Wei Tian in disbelief. "Okay, master, let's start. But now I don't have the flame." Wei Tian was really helpless this time. Ancient Gu told him before that Gu masters also need flames to refine Gu pills, and the flames first start from the earth fire, then the sky fire, and then the real fire. As for the divine fire, Wei Tian can't touch it yet. "I knew you would ask this. First, you can find some wood as fuel, try to refine a few powerful Gu pills, and then look for a trace of Earth Fire seeds when you have the opportunity." Gu Gu said directly. Wei Tian understood what Gu Gu said. A moment later, he had already found some wood from outside. Just when Wei Tian was about to light the wood, Gu Gu hurriedly stopped him and said, "You can't light it directly. Since refining the Gu pill requires your willpower, you must use your willpower to light the wood." " Using your mind? Isn¡¯t this making things difficult for me, Master?" Wei Tian said in surprise. "Do you think it's easy to refine Gu Pill?" Gu Gu rolled his eyes at Wei Tian. After Wei Tian stuck out his tongue helplessly, he could only watch the ancient Gu prepare the materials. "Refining the powerful Gu elixir does not actually require a lot of materials. You only need a pure Yang grass and a second-level earth attribute beast elixir. You must have a lot of these things in your storage ring." Gu Gu directly extended his hand to Wei Tian. ¡°You¡¯re asking me for materials again.¡± Wei Tian muttered reluctantly. "You kid." "Hehe." Wei Tian looked at Gu Gu's strange expression and smiled stupidly. "First use your mind to ignite the wood and preheat your Gu Cauldron." Gu Gu pointed at the wood on the ground and said. After taking a look, Wei Tian finally retracted his intention to play, and then the power of his thoughts in the mud ball began to gather together. After a while, Wei Tian's power of thoughts was completely condensed, and then his eyes were fixed on the wood. Stare. ?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? Two balls of flame have appeared again in Wei Tian¡¯s eyes. "Bang!" Then there was a muffled sound directly from the wood, and then a trace of green smoke began to emit from the wood, and the color began to turn black. Wei Tian did not stop his movements when he saw such a change, but continued to exert his mental power towards the wood. "Bang!" There was another sound, and it was this movement that directly caused the smoking wood to catch fire. Although the flames were very weak, they began to spread slowly. The ancient Gu on the side kept nodding. "First use a low fire to preheat the Gu Cauldron. It will take about a quarter of an hour." Gu Gu said. Wei Tian understood the meaning of the ancient Gu, so at this time his power of thought no longer increased, but he continued to control the development of the fire. A quarter of an hour finally passed. Gu Gu saw that the temperature was already radiating from the Gu Cauldron. He nodded slightly and said, "Well, you can put the Pure Yang Grass into it now, and the flames can be increased appropriately." Wei Tian followed Gu Gu's instructions. method, put a pure Yang grass directly into the Gu Cauldron, and then increased his will power by two points again. Gu Gu kept watching and preaching, while Wei Tian watched the flames meticulously, fearing that something would go wrong. This was the best way to test his ability to control his mind. An hour finally passed, and I saw that the Pure Sun Grass had completely turned into liquid and existed at the bottom of the Gu Cauldron. "Okay, now put the beast elixir into it. The flames can be bigger, and this time I won't remind you that everything is up to you." After Gu Gu said that, he stood up and sat on the chair, closed his eyes and rested. Wei Tian didn't expect his master to be so irresponsible. He just said a few words and started to work as a hands-off shopkeeper. However, he couldn't be distracted now, so he didn't bother to argue with his master. Instead, he started to figure out how to refine it. Got the poison pill. Half an hour, one hour, two hours, two and a half hours. Time passed so quietly, but there was still no movement in the Gu Cauldron. "Bang!" Just when Wei Tian was getting a little anxious and was about to increase the flames, he heard a crisp sound coming from the Gu Cauldron. Wei Tian hurriedly withdrew his willpower, opened the lid on the Gu Cauldron and slapped it. From the body of the tripod, a black Gu Dan flew out directly. With excitement on his face, Wei Tian took out the jade bottle he had prepared long ago and put the black poison pill into it. "Master, I succeeded. Look, this is the Gu pill I refined." Wei Tian's face was full of joy. Wei Tian originally thought that Gu Gu would praise him, but he didn't expect that Gu Gu didn't even look at him. After successfully refining the powerful Gu pill, it was dark red, and there was a hint of masculinity in the smell. Look at what you have refined. Something, it smells like paste. "How could it be? As soon as it took shape, I took out the fire and took it out. How could it be mushy?" As he spoke, he started to smell the small mouth of the jade bottle. When the smell of the powerful Gu Pill penetrated Wei Tian's nose, his expression also changed. There was indeed a paste smell in it. It was obvious that Wei Tian failed in refining the Gu Pill for the first time. "Master, it was indeed unsuccessful." Wei Tian lowered his head and felt a little disappointed. "Continue refining." Gu Gu's voice was extremely stern. Wei Tian didn¡¯t have any refutation, and went straight to Chu Ring to find another set of materials to start his second attempt. Whether Wei Tian would succeed the second time is still a mystery.
