He Jingjing looked at the black dragon with admiration and admiration! ¡° Craftsmanship is something that if you have it, you have it, and if you don¡¯t have it, you don¡¯t have it, it¡¯s clear at a glance. Hei Jiao obviously has a few brushes. He Jingjing initially thought that he was bragging, but now it seems that he is obviously being modest. Along the way, He Jingjing fell into a rock-like silence. It wasn't until she arrived at the Juling Sect's medicine refining hall that He Jingjing held back her words: "We're here." Except for the elders who were in charge, basically all the disciples of the Juling Sect went to Yutuo Mountain to mine. This also resulted in only a small number of disciples in the alchemy hall continuing to work. When He Jingjing introduced the identity of the black dragon to this group, as expected, he won a large number of people who made a gasping sound. It¡¯s just that the sound lasted for a short time, and the disciples went their separate ways. "I don't dare to boast about anything else, but as for the materials for refining medicine, if even the Giant Spirit Sect doesn't have the materials, your work elsewhere will be in vain." "I think, refining the marrow cleansing liquid" Black Jiao looked at it. He glanced at He Jingjing and said in a dull voice. "Marrow-cleansing spiritual liquid?" He Jingjing's voice suddenly rose, with disbelief on her face: "You want to cleanse the marrow spiritual liquid? Do you know how high the failure rate of the marrow-cleansing spiritual liquid is?" "50%, a third-grade elixir pharmacist, There has to be a 50% failure rate. By the way, what are you doing refining human elixirs? Do you want me to help you? " "I have a human friend who made it for him. "Just tell me if you have the ingredients for the marrow cleansing liquid." "Yes, there are as many ingredients as you need for the third-grade elixir." He Jingjing looked like she was waiting to see your joke: "I have a fifth-grade elixir furnace here." I have them all, do you want to lend them to you?" Black Jiao shook his head. Declined her kindness. Marrow Cleansing Liquid is a third-grade elixir, mainly used to increase bone marrow strength. Let the body produce more qi and blood, increasing the chance of success in breaking through the nine heavenly orifices. The marrow-cleansing liquid is a kind of liquid. The materials for refining this elixir are not expensive. It mainly uses Yuanhuo to fuse dozens of materials together and maintain the liquid shape. It is very particular about the control of the fire. ?Subtle changes in heat can produce hugely different effects. Only through years of trials, the characteristics of the various medicinal materials of Marrow Cleansing Liquid can be understood. Have a very deep and unique understanding. Only by relying on experience can we seize the fleeting opportunity and successfully refine the marrow cleansing liquid. This is why He Jingjing thinks that Black Jiao cannot do it, because it is too young and cannot have so much practical experience. Even if he is an expert in controlling fire, it won't work. Because it doesn¡¯t understand the dozens of material properties of the marrow cleansing liquid. But this does not prevent He Jingjing from using the ingredients of the marrow cleansing liquid in exchange for the extremely rare ambergris saliva. The use of marrow cleansing liquid is very restrictive. Usually it can only be used when the ninth level of Nascent Xuan is not yet stable. After this stage, it will have no effect if used again. So Ye Qing only bought ten ingredients for the marrow cleansing liquid. In exchange, Ye Qing had to pay five hundred drops of ambergris. The price of a low-grade marrow cleansing liquid is three thousand jade spirit stones. If it is a top-grade marrow cleansing liquid. Five thousand jade spirit stones are needed. Or they are all alchemists, each of them is worth a lot of money. Of course, if there is no alchemist with matching strength, it is easy to attract the "shearing" of the strong. Therefore, it is better for Ye Qing to be more careful before he has strong strength to protect him. Ye Qing would not tell He Jingjing that he had a minimum 95% chance of success in using the marrow cleansing liquid. What remains is uncertainty. It's still a matter of medicinal materials. The medicinal materials were changed and ambergris was paid. Black Jiao glanced at the alchemy where the Red Tiger Copper Furnace was placed. That was the place where he worked as an errand, and it was also the place where he received the inheritance from the old man Xuan Jia. A loud explosion quickly pulled the eyes of Heijiao and He Jingjing into the room. There was a furnace explosion in the elixir shop where I was working as an errand! The steaming heat wave, the thick smoke, the door that was forced open, and the choking smell of the elixir paste made Ye Qing immediately realize the cause of the explosion. Usually, furnace explosion will only occur on high-grade elixir furnaces. The elixir furnace at the door is just an ordinary item, and there is no possibility of furnace explosion. Several disciples who had greeted the black dragon turned around and ran out of the thick smoke in ragged clothes. "Senior sister it exploded it exploded." "I'm not blind." He Jingjing, who had just done a business and was in a slightly better mood, immediately turned bad again. The Red Tiger Bronze Furnace has long been requisitioned to study a semi-finished elixir formula recorded by He Jingjing from the old notes of Xuanjia in his early years. The fourth grade elixir¡ª?Five Qi Dan. Use the true blood of five monsters with different attributes to refine a Five Qi Pill. It can be used for cultivators in the spiritual void realm to replenish the five qi in the body in large quantities, and strive to enter the divine martial realm where the five elements are not added to the body as soon as possible, and they can drink iron juice and bathe in magma. They were right to use the Red Tiger Copper Furnace with a lower flame temperature to study the Five Qi Pills. But the problem is that the formula of the Five Qi Dan is wrong. Although it is only a little wrong, when it is magnified to the fourth-grade elixir, it is completely wrong. "I'm leaving first." Ye Qing couldn't help but want to run away, otherwise he wouldn't be able to control himself from laughing. "Wait a minute~ Do me a favor." He Jingjing caught up from behind and her tone became more tactful: "I heard you dragons are all natural masters of controlling fire. Can you help me control the temperature of the flames?" "It's useless. It's not like you don't know that the cause of the furnace explosion was not the heat." He Jingjing immediately looked at the black dragon with suspicious eyes. The cause of the furnace explosion was not the heat. How did this dragon know? Ye Qing saw her suspicion at a glance and excused himself: "I am born with a very keen sense of fire aura. The flame stone you used, I could sense it immediately. There are usually two types of flames used in refining medicine. One is for cultivators to directly use Yuan Fire to temper materials, and the other is to use flame stones, Na Yuan Stones, Na Yuan Pools, Fire Spirit Stones and other treasures that contain fire aura to release flames to temper materials. Direct calcination is either done by stupid young people or by those who are highly skilled and courageous. High-grade elixirs also come from the hands of these people. The latter is superior to being extremely stable, but lacks the spirituality to follow one's heart. The refining of elixirs can only be done step by step, which is relatively rigid. "The house is indeed calcined with flame stones. He Jingjing was once again impressed: "Awesome!" " After saying that, He Jingjing smiled to herself, feeling that she was a little sick and rushed to seek medical treatment. What was refined in it was the elixir formula left by a master in refining medicine in ancient times. This black dragon would definitely not understand it. Seeing that He Jingjing had no intention of staying, Ye Qing controlled the black dragon and ran away. After leaving the gate of the Giant Spirit Sect, he flew into the sky. When night fell, the black dragon sneaked back home under the cover of darkness to prepare the elixir. Ye Qing also left the canyon near Yutuo Mountain, and then ran at a thunderous speed. As he ran, his body tore through the air, making a whistling sound. Ye Qing's speed was half as fast as entering the eighth level of the Mysterious Realm, and he could faintly break through to the ninth level of the Mysterious Realm. He could stand at the peak of physical strength that a mortal could achieve. Under the moonlight, an unusually weak reflection whizzed past the front of his field of vision. Come over. This reflection is extremely fast and is directed at Ye Qing! Even with Ye Qing's eighth level cultivation, it is difficult to escape this sneak attack. His skill saved Ye Qing's life. The two big muscles in his legs stretched out, and Ye Qing instantly dodged to the side, and then with a pop, a dazzling spark burst out from his left shoulder. Ye Qing fell down in an extremely embarrassed state. On the ground, dozens of scales were knocked off the left shoulder of the golden owl armor. Three figures in black clothes and face masks quickly surrounded him. The lame visitor burst out laughing when he saw Ye Qing clutching his shoulders in pain. His eyes looked particularly ferocious under the moonlight. It was purely intuitive that Ye Qing could guess who was attacking him. This laughter, this figure, this slightly lame right leg, could it be other than Wan Feiyu who provoked Ye Qing at the foot of Jade Camel Mountain and later had his right leg broken by Ye Qing¡¯s kick? Feiyu, look at your virtue of hiding your head and showing your tail. "Ye Qing stood up slowly, with his whole body on guard, and said in a low voice: "You didn't beat me last time, but you got two helpers this time? "Wan Feiyu, who was covered with a turban, was shaken and looked extremely flustered. But before Ye Qing could continue to speak, he suddenly relaxed and laughed arrogantly. "Since you have seen through it, I won't hide it. . "Wan Feiyu's eyes were full of victory, and he pulled off his face towel, revealing a somewhat distorted face. "I have waited so hard for you, and today I can finally use your blood to wash away the shame of that day. "
