Learned quenching adds help, and refining the spiritual fire is more powerful.

In a stick of incense, a giant sword that looked the same as before appeared under Huang Yu's hand, but it was at least one circle bigger, nearly half longer, the giant sword was formed, three trajectories were carved, and a sky-high light lit up, Huang Yu regained his weapon, took the giant sword in his hand and waved it, he was quite satisfied, this time, he deliberately increased the weight, to match his current strength and the body shape under the Gangqi Method, but if he wanted to hold the giant sword in his usual state, he would have to carry it, this giant sword was too big for him in a normal state. Huang Yu's cultivation at this time was much stronger than before in the upper domain, and it was extremely easy to depict the three trajectories, and he didn't know how many trajectories he could depict in one breath now, but after the depiction was completed, he only felt a slight movement.

"It's the best mystery, a good one. But I'm very strange, big brother, why do you just beat when processing materials, and don't do quenching or normalizing, annealing, tempering and other treatments after molding? Although those are trivial matters for the refining weapons of this world, which are only used by ordinary mortals to build weapons, these procedures can strengthen the weapon itself, and with your three mysterious trajectories, I feel that it can be improved. Hachi exclaimed and asked questions.

"What kind of procedure is that?" Huang Yu asked, not only did they not have those kinds of fire in their Huang family's craft, but they also didn't mention it in books like refining tools.

"I heard that when my eldest brother was ramming those metals, the rhythm was very subtle, and it should be able to perfectly integrate the characteristics of several metals, so that the effect of quenching and the like would be greatly reduced, but it can make your refining more perfect, do you think it is necessary to learn, big brother? Hachi said, looking rather regretful about mentioning it.

"Naturally!" replied Huang Yu firmly.

"Alas, well, normalizing and annealing don't need to be too well understood, quenching and tempering are more useful. Annealing is to let the metal utensils be cooled at a very slow rate, so that the internal structure of the metal can reach a balance, improve the performance, can also be regarded as the prelude to quenching; normalizing is to directly let the metal be cooled in the air after forming; quenching is to let the red forming utensils be covered with a layer of black ash on the surface, put them into the low-temperature condensate, the temperature will be rapidly reduced, and the wear resistance and fatigue resistance of such appliances will be improved; tempering is generally used in combination with quenching, the quenched metal appliances are still a little brittle, in order to reduce the brittleness of the metal, the quenched appliances are placed in a hot space for a period of time, which can effectively reduce the brittleness。 Hachi said helplessly.

"What do you mean by getting that condensate?"

"Water in general. And then there's the kind that absorbs heat very quickly. Xiao Ba's face was helpless, and Huang Yu also saw what a dragon's expression expressed.

"Oh, I see, the ice converted from the spiritual power of the water attribute can also be used, right?"

"Yes. ”

After that, Huang Yu created another giant sword, which was similar to the previous one, this time after the giant sword was formed, it immediately summoned dark water, and instantly traveled through every part of the giant sword at an extremely fast speed, absorbing almost all the heat, and the giant sword was completely cold.

"It's too fast, it will become more brittle, and the speed can be reduced by half, this is not an enemy, as for the ruthlessness of killing people as soon as it comes up. Also, is that half a drop of dark water?" Hachi said.

"Yes, then this one is a waste?" Huang Yu was a little reluctant, but he still carved three trajectories on this giant sword, and still got a superb mysterious weapon.

"Big brother, where did you get these trajectories, it's amazing, it feels more powerful than those spirit-level magic circles in my inheritance memory, it goes straight to the essence, it has the ability to turn decay into magic, and the dark water is very useful to me, and then I will leave some when I encounter it." Xiaoba's admiration can make a tyrannosaurus with inherited memories admire, which shows how extraordinary that trajectory is.

"Okay, after we go back to my house, we'll go to find the dark water, there should be a lot, as for the trajectory you said, I looked at a formation and realized it. Huang Yu said, and began to get busy again.

"It's my big brother! Where is that formation? I'm going to see it too. "Hachi is in spirit.

"Okay, but I don't know the way, Brother Qiang knows, go back and let him take us there. Huang Yu said that he was very insensitive to the road.

"Big brother, do you still have big brother?"

"I not only have an eldest brother, but also grandparents, parents, wives, fathers-in-law, and sisters-in-law...... I'll introduce you one by one, by the way, it's not okay for you to appear in front of people like this, you have to transform it, otherwise someone will definitely take you away, and the eldest brother may also be killed, and now I'm still very weak. Huang Yu said, and began to lead Xiaoba to the road.

"It's still a big family...... Alas, well, the dragons are the best at transmoging something, eh...... I'll transform into a little python. Hachi said that the dragon horns, dragon claws, and pitch-black dragon scales on his head changed for a while, turning into a crimson python, and his body shape did not change much.

"Flame pythons can't float, right?"

"That is, the dragon clan can float in the air as well as in the water, how can a demon beast like the Yan Python be. Xiao Hachi said.

"And you're still floating?"

"Alright then, I'll get down to the ground...... But there is dust on the ground, and I will wrap it around you. As he spoke, Hachi floated onto Huang Yu's body, shrunk in size, and turned into a small snake with a foot length, wrapped around Huang Yu's arm, becoming inconspicuous, but adding a strange aura to Huang Yu.

"Okay, then I don't have to introduce my family to you, but you have to meet Nana and their family, as well as Yuan Lie'e, and the others can see a few fewer people. Huang Yu said, and then buried himself in building.

The quenching again was really successful, Huang Yu felt that the giant sword was stronger than the previous two, and it surpassed a lot in toughness and balance, and the quenching was really useful.

When the sky was dark, Huang Yu made eighteen weapons of all kinds, which he gave to the Nayan tribe, but after the eighteen weapons were built, he still didn't have the feeling of catching the treasure, he felt that it was because he hadn't built enough, but it was already very late, and he had to rush back.

"Big brother, why don't you use the Nirvana Fire Refiner?" asked Hachi on the road.

"Earth fire can give a certain quality to the artifact created, and the positive enhancement is the majority, so I still give priority to using earth fire, and then because I don't know how to use Nirvana fire yet, I need to be familiar with it before I can use it for refining. ”

"That's right, the earth fire will give the appliance an enhancement or weakening, it is very weak, the fire of Nirvana is different, big brother, you can absorb the fire of Nirvana so easily, it should be very easy to manipulate, just like extracting the spiritual power of the golden pill from the fire storehouse, the fire of Nirvana is the ignition fire of the fire of life, which can give the attributes of the instrument powerful, it is the flame that is easiest to make the instrument have spirituality, and it is an excellent fire that refiners can not encounter, isn't it a waste if you don't use it quickly?"

"Oh, is it so strong?" Huang Yu's eyes lit up after listening to it.

"And the general refiner uses his own fire spiritual power to refine the weapon, which can more accurately grasp the changes of the instrument, and the internal engraving circle is also easier to achieve, so even the monk who has just entered the refining process will try his best to use his spiritual power to build, you are good, and seek the near and far. ”

"I've seen this technique, but it's not anything outstanding. Huang Yu said that the knowledge he received compared the two methods of internal carving and external carving, and the results were both good and bad.

"What's wrong with this world, I've lost too much inheritance!" Xiao Ba sighed at the sky, and then looked at Huang Yu with some resentment and continued: "The most obvious advantage of the internal engraving is that it is not easy to be seen by others, and it is not easy to wear out; secondly, it is more effective to change the internal texture of the instrument, so that it becomes stronger unconsciously; finally, it is also the strongest benefit, it can more smoothly conduct the user's spiritual power, and there is not much gap between the mysterious weapon-level equipment, and when it comes to the treasure weapon, it is completely different, and a little advantage can affect life and death." Xiaolong said, I have to say that the inheritance memory of the dragon clan is too comprehensive, and many experiences are like experiences.

"Then hurry up and go to the Nayan tribe to try it. Huang Yu was a little impatient when he heard this.

All the way, soon returned to the Nayan tribe, at this time the Nayan tribe was brilliant, and was preparing to celebrate, to celebrate that only the Nayan tribe among the four tribes was preserved, and the hidden danger of the giant was removed, plus the little princess of the Nayan tribe Nayan Zhenna's wedding is imminent, each of them is worth celebrating.

"Hey, my uncle is back. Many people in the Nayan tribe saw Huang Yu come back, and some people shouted loudly.

"Grandpa is back, the celebration begins!" shouted again.

The entire Nayan tribe was immediately enveloped in a jubilant atmosphere, and the enthusiastic and penetrating laughter had a strong contagious effect, not to mention that the people of the Nayan tribe who survived the previous battle were grateful and worshipful to Huang Yu, and the feelings expressed directly and strongly in the almost primitive tribe, Huang Yu and Xiao Ba were quickly infected by all kinds of feelings and integrated into it, Xiao Hachi drank a lot of Nayan tribe's own wine, a little dizzy, and Huang Yu drank more, almost everyone came to toast him, there was a slight gap, it was also Yuan Lie'e and Na Yan who drank the dragon with him in a big cup, even so, his face did not change, and in the end, everyone fell, only he was still standing firmly。

"It's my big brother, it's amazing! I'm going to sleep. Hachi said before falling asleep on the ground.

There are many women in the Nayan tribe who also participated in the celebration, but they do not include girls such as Nayan Zhenna and Nayan Zhenling, Huang Yu stood and looked around, and did not see Nayan Zhenna, and his heart was not lost, and the days after that were still long, and some were together.

"It's time to try the Nirvana Fire Refiner. Huang Yu thought and took out various tools and materials that had been processed before.
