Elder Song knew that Xu Yi was calling for robbery. It was obvious that this kid wanted to change the topic, but he said he changed the topic.

But this kid caught the point, making his face turn red. For a while, he really couldn't make a strong statement, so he had to go shamelessly and said, "Who told you to let me follow you to bet, earning tens of thousands of gold. With my temper, I don't spend money, and I feel uncomfortable. I just heard that a batch of good goods came to Tianshui City, and I was afraid of missing it, so I had to rush over. Besides, didn't I leave a letter to you, and I didn't let you wait for nothing."

Xu Yi was angry and thought to himself that people really couldn't get close to each other. Earlier, seeing Elder Song's extraordinary talent and a skilled master's style, he finally narrowed the distance and ignored it completely and showed his shameless face.

"What you always say is that the boy is talking too much. Today, the boy came to fulfill his contract and I don't know when the construction will start."

Xu Yi suddenly got rid of the entanglement of who is right and who is wrong, and said with a smile.

Elder Song's tongue was knotted suddenly, and he prepared a lot of shameless words, but it was stuck in his mouth.

"Is there anything wrong today?" Xu Yi asked.

"Yes, how come there is nothing wrong?"

Elder Song was so hurt that he simply introduced today's mission.

This time, Elder Song will continue to test the method of casting blood vessels to see if he can train a medium-grade blood-drinking knife with the help of Xu Yi, a stable fire supply device.

Since Xu Yi came to fulfill his contract, Elder Song has always done whatever he said, without any nonsense.

But when Elder Song first sent a boulder-sized black iron block into the cauldron, started the earth fire, and asked Xu Yi to start pulling the box.

Half an hour later, Elder Song bets into the cauldron one after another, four or five kinds of materials. In an instant, various colors of smoke in the cauldron transformed, surrounding the colorful clouds, illuminating the entire room with heavy light and shadow.

Another stick of incense, Elder Song got a cloth bag from somewhere and asked Xu Yi to take a break, open a secret door from the side of the cauldron, aim the cloth bag at the secret door and open it, and immediately a scarlet liquid poured in.

Xu Yi was shocked. This bag of liquid was blood, human blood.

The smell of blood is so familiar to him today.

A bag of blood was poured into the cauldron. After a few breaths, Elder Song stopped the ground fire and said with a smile, "The blood-drinking knife I want to forge this time has been raised for a long time. All the equipment has reached the middle-grade choice. The key is to rely on your kid's offering of fire and have a good rest. I still don't know how much blood these stubborn stones need to suck to drink enough. Let me be good at forging into beautiful jade."

"The elder wants to forge a blood-drinking knife, not just a metal and iron weapon. Why did I see several materials just now, and it is impossible for me to be metal and iron? Why is this? Is it true that the five elements are also dialectical about the refining of weapons?"

Since Xu Yi came to refine weapons, he could see the great master refining weapons with his own eyes, so he naturally did not want to miss this on-site teaching.

Elder Song raised a thumb and praised, "I knew you were not an ordinary person. I didn't expect that your understanding was so high. Yes, refining weapons is like refining medicine, which is the way of synthesis. If the way of synthesis is to reach the peak, it cannot go against the way of nature. What is the way of nature? The circulation of the five elements, and the harmony of yin and yang. The best magic weapons and elixirs all need to pay attention to the balance of the five elements and the harmony of yin and yang."

"Take the blood-drinking knife at this moment, if I am practicing the hoe to the ground, the knife to cut vegetables, cut wood and make fire, and swing the hammer and hit iron, it will be done. However, the blood-drinking knife is a blood vessel after all, not only to be extremely sharp and strong, but also to be able to accommodate true qi. There are many ways of doing it, and the requirements are naturally very high. The five elements are unbalanced, and it is difficult to be firm and sharp, and the Yin and Yang are not adjusted, the lines are not solid, and the true qi cannot be penetrated. Even if it is barely forged, it is just a handful of ******, so what's the use?"

Xu Yi nodded and was still waiting to ask again. A light sound came from Elder Song's waist. The old man checked the movement in the lower cauldron, told Xu Yi to rest with peace of mind, and quickly left the refining room.

After less than half a stick of incense, the old man turned around and looked anxious. He ignored Xu Yi's meditation and breathing, and said anxiously, "Boy Xu, I'll ask you, the mirror in the water really handed over the iron spirit to your Police Department? And your Police Department lost the iron spirit last night? Return to me quickly!" As he spoke, he rubbed his hands and scratched his forehead, and was very anxious.

"This is indeed the case." Xu Yi did not expect that the old man suddenly noticed this issue.

"What! You, you...ah, I don't know who will get this kind of treasure."

Elder Song's face turned red and he was so anxious that he kept muttering, "If I had known that Linglong Pavilion had sold iron spirits, I would have bought them even if I lost all my money. How could I let anyone named Shui go? Ah..."

Elder Song's unlucky sigh seemed to be hiding a thousand feet underground, but he was still struck by lightning and was extremely depressed.

Xu Yi thought and said, "Is it possible that someone had just informed the elder of the thief that the thief had been lost."

"Isn't it? If you want to say that the wine bags of your Police Department are all for dry food, so many people can even steal them if they are guarding an iron lump? Hi, it would be fine if the one named Feng had to go, but now I don't know who has fallen into my hands, which makes me itch."

Elder Song was anxious and couldn't afford it, so he tossed and turned.

"Isn't it just a piece of iron spirit? It's no big deal. I'm not to hide it from the elder. When I was guarding last night, I played with this thing. Apart from being able to transform into shapes, it's not strange. Oh, by the way, I heard that iron spirit is used as an excellent material for forging tools, but there are many materials suitable for forging tools in the world, and it's not the only iron spirit. So I think the elder doesn't have to worry about gains and losses."

This statement seems to be consoling, but it actually makes people laugh.

If it weren't for the adventure last night, Xu Yi might have thought that the iron spirit was a suitable equipment for forging magic weapons. However, last night's adventure made him deeply understand the magic of the iron spirit, and his suspicion about the iron spirit in his heart became more and more profound.

At this moment, Elder Song looked in a daze and thought to himself that in terms of his knowledge of the objects, no one could match Elder Song's masters, so he wanted to lead him to express his insights.

Elder Song sighed, wanted to speak but stopped, and finally waved his hand and said, "You are not a person in this way, it is difficult to understand the wonders of this way. It is useless to say more. Let's go and rest, and temper it!"

At this time, the colors in the cauldron had completely dimmed.

Elder Song opened the earth fire and the real tempering began.

Just like that day, Xu Yi pulled the wind box, Elder Song muttered something, and waved his palms on the cauldron from time to time to stimulate his energy.

Xu Yiyuan thought that this tempering would take as much time as last time. With the power of the Three Ox that he has now cultivated into the first level of "The Power of the Power", it would be easy to control this wind box.

I didn't know that this pull took nearly three hours, and the thousands of pushes and pulls made him exhausted and numb.
