A few hours passed, and after Liu Zhao prepared the last accessories, he breathed a sigh of relief, and after a long time of concentration, he was a little overwhelmed, but he finally matched them all!

At this time, Ah Cha came to Liu Zhao's side and meekly helped him wipe his sweat.

After Ah Cha helped Liu Zhao wipe it, Liu Zhao looked at Ah Cha with tender eyes, Ah Cha blinked his watery beautiful eyes and smiled slightly, and the encouragement in his eyes was naturally indispensable.

Liu Zhao felt this encouragement from Ah Cha, and his heart couldn't help but perk, and then he put his eyes on the materials of those refining weapons.

What he should do now is to bring these purified ones back into the furnace and let them fuse together!

This step is obviously more difficult than the previous one.

If you want to fuse metals with different densities, properties, and melting points, you can imagine how difficult it is, not only to test the refiner's ability to operate, but also to test the refiner's will and calculation ability, and these Liu Zhao also learned the properties and usage of each metal from the book "Refining"!

And it's a long-term job, and it takes a long time.

Liu Zhao looked at the metal in front of him, and then at the Kongming Sword that was lying calmly in another furnace.

"At this time, the Kongming Sword has only reached a third of the level, and if you want to completely smelt the Kongming Sword, it seems that you will have to wait for a while!" Liu Zhao thought to himself.

Immediately looked at the metal in front of him, Liu Zhao also roughly estimated, I am afraid that after he has fused all these metals, the Kongming Sword will almost be completed! The timing arrangement is also just right, and there is nothing missing!

Then he picked up the fire tongs with high melting resistance and put the metals in according to their melting points.

Metals with different melting points naturally have different times to turn into molten iron, so what Liu Zhao has to do is to put in the metal with a high melting point first, and then put other metals in it when the melting point of this metal reaches the same as the melting point of other metals, so as to avoid some trivial troubles and speed up the efficiency of doing things!

After Liu Zhao put them in, he came to a grooved place, which was where the final weapon was formed, and it was also an important step to complete the advancement of the Kongming Sword - casting!

The formation of weapons is the role of this step, and Liu Zhao clearly remembers the refining steps in "Refining Tools":

The first step is smelting, where the metal is melted in a furnace and then removed when it reaches its melting point. The second step of purification is performed.

Then came the third step of returning to the furnace and remelting, which is the step that Liu Zhao did at the moment.

This is followed by the important fourth step of casting, where the fused metal is introduced into the groove and it is formed!

The fifth step is re-forging, which is to carry out gravity forging of the weapon, and of course, this step also uses different re-refining according to different weapons!

As the name suggests, endowing the soul of the weapon is to inject a trace of the soul of the cultivator into the weapon, endow the weapon with spiritual consciousness, make it his own natal weapon, and make up for the lack of soul, so the role of the natal weapon is very important for the cultivator!

This last step is only done by those who are truly attentive to this weapon, after all, it is not pleasant to separate a trace of soul from one's own soul.

As for the previous weapon, Liu Zhao didn't need to do that step at all, he just injected some painstaking power, but the consumption was not small!

And the weapon refined in this way must be lower than the weapon that is endowed with spirits, and the step of endowing spirits can basically be completed by cultivators, provided that you encounter a weapon that accompanies you!

And Liu Zhao is naturally dealing with the empty sword in front of him wholeheartedly, and he can't tolerate a trace of sloppiness, once he fails, not only will his previous achievements be wasted, but even the cultivators will be counterattacked, it is a counterattack on the soul, and it will not taste good!

Time passed little by little, Liu Zhao was also staring closely at the metal in the furnace, and when their melting point was about to be about the same, Liu Zhao put other metals in it and smelted together.

In the end, Liu Zhao's whole body clothes were already wet with sweat, and the sweat fell to the ground, but he persevered with strong perseverance, his lips were kept closed, his eyes were staring at those metals tightly, but he was calculating their melting points in his heart, which can be described as laborious and laborious!

Ah Cha watched Liu Zhao's hard work on the side, and his heart throbbed, but he was also afraid of disturbing Liu Zhao, so he had to silently wipe the sweat off Liu Zhao's face, but Liu Zhao's sweat seemed to be unstoppable, Ah Cha just wiped it dry, and the sweat came out of his pores again!

But Ah Cha was not too tired, and kept wiping the sweat on his face for him!

Half a day passed, and only five pieces of metal of different colors were put into the furnace, and then there were more than ten unknown metals on the display table!

The time it took must have been more than twice as long as before, but Liu Zhao still insisted with great interest and didn't feel bored at all!

Because the more he went to the back, Liu Zhao was surprised to find that his mental power seemed to have been tempered and began to grow!

When Liu Zhao's mental strength broke through to the Wuchen period, he had already reached the strength of the middle stage of Wuchen, and now after a few days of tempering, he faintly began to move towards the late stage of Wuchen, which is also the reason why Liu Zhao was happy in it, and he didn't feel tired at all!

Liu Zhao also roughly estimated that after the end of this refining, the benefits he would get might not only be the Kongming Sword in front of him, but there might also be other aspects, and the current increase in mental power is a good example!

So Liu Zhao began to work hard for the advancement of the Kongming Sword under such circumstances!

Time passed quickly in Liu Zhao's refiner, Liu Zhao seemed to have forgotten the existence of time, and at this time, in his eyes, there was only the current work - fusing metal!

Two days later.

At noon on this day, the change finally happened, and in the past two days, he had never rested, obviously he didn't know how much time had passed, and he also got some food to fill his stomach in the middle, and then focused on the metal in the furnace!

And at this time, Liu Zhao finally smiled, because all the metals in the furnace were melted, Liu Zhao saw this, so he swept the empty sword in the other furnace, the empty sword at this time is about the same, and it is about to reach its critical point, but there is still a long time, Liu Zhao is not in a hurry, because he has other things to do now!

Liu Zhao looked at the more than ten kinds of metals with different attributes, and exhaled turbidity, what he had to do now was to fuse them together.

And beside Liu Zhao, Ah Cha's figure suddenly appeared, without a trace of sound, she was also afraid of disturbing Liu Zhao.

But in Liu Zhao's heart, he thought that Ah Cha had always been by his side, and he didn't find that Ah Cha left halfway!

Liu Zhao slowly brought the metals closer together in the furnace, and at this time, Liu Zhao held his breath, his eyes staring at the metal liquids slowly melting together.

The metal liquids of different colors flowed, which was very beautiful, but Liu Zhao was not in the mood to appreciate these now, what he had to do was to melt these metal liquids together!

After Liu Zhao's tempering, the purity of the metal as high as 99.9% showed its difference at this time, and the dazzling light flickered in the furnace, but it could not affect Liu Zhao's operation at all!

The more he got to the back, Liu Zhao's body trembled, because he encountered resistance, from the resistance between the metals, from the attribute rejection between them!

Even so, Liu Zhao still persevered, in front of Liu Zhao, the dazzling light lit up, radiant, filling the entire refining room, quite good-looking, Ah Cha on the side saw this, and couldn't help but flash a trace of inexplicable light in his eyes!

And after a few hours of strong struggle, Liu Zhao's originally trembling body gradually stabilized, and then the dazzling light in the refining room gradually disappeared, and finally disappeared into the furnace.

Seeing this, Liu Zhao, who was in front of the furnace, finally exhaled, looking at the metal liquid flowing in the furnace, the corners of his mouth raised slightly, and colored lights flashed in the liquid.

Immediately after that, Liu Zhao set his eyes on another furnace, and saw that the Kongming Sword was almost there, Liu Zhao gestured to Ah Cha, Ah Cha nodded, and then with a move, the Kongming Sword in the furnace suddenly flew out, and was immediately guided by Ah Cha and landed in the groove!

Seeing this, Liu Zhao looked at the Tonghongkong Ming Sword, and the lines on its sword body became slightly clearer, but Liu Zhao still couldn't understand it.

Immediately after, Liu Zhao's eyes froze, and he led the liquid in the furnace that shone with colored light into the groove!
