"Quenching, what is quenching!"

"It is to put the cooled blade on the fire again, and when it is about to melt the edge, use a hammer to continuously beat and forge it to increase the density, and then put it on the fire to burn until it melts the edge, and put it in water. ”

After listening to the forging and quenching of the Purple Gold Dragon King, Mo Han still looked confused, and it seemed that the Purple Gold Dragon King didn't understand very well.

"Where did you get the weapons, blades, armor and other equipment you used?" Mo Han suddenly thought that Old Man Dugu and the Purple Gold Dragon King also needed to use various tools, and couldn't help but ask.

"I bought it!"

"Inheritance!"

What I bought is the reply of the old man Dugu, and what is inherited is the reply of the Purple Gold Dragon King.

Mo Han looked stunned for an instant, it turned out that it was a blind man leading the blind man to walk: "Old man Dugu, you tell me the truth, how did you get the jade slips you gave me before to break the ban on the formation?"

"I carved it myself. The old man Dugu was a little hesitant, "Well, what I saw on the tree before, one by one, I thought I could break the formation prohibition you faced, so I carved it out for you."

Mo Han swore that in addition to the problems in cultivation in this life, the problems in the alchemy refining formation would not ask the two of them, these are the two pits, the sinkholes.

The casting of the heavy sword has reached the embarrassing point of not being up and down, and Mo Han decided to follow the method of the old man Dugu, first cast the sword embryo, and then put it in the reincarnation flame to roast and quench it again.

Thinking of doing it, there was no container for the azure molten liquid in the crucible, Mo Han simply lifted the metallurgical table and carefully poured the azure molten liquid into the sword box.

Cooling down was another waiting process, and Mo Han didn't know how high the temperature of the azure melt was, but he definitely didn't dare to touch the sword case before it was completely cooled. Just kidding, it took half a month for the Reincarnation Flame to completely melt the Taiji Xuanmagnetic Heavy Sword, which could be done with more than ordinary temperature.

The way to check if the sword case was completely cooled was simple, Mo Han found a river, took a large puddle of water, and dripped a drop after a while.

At first, the drops of water did not fall on the sword case, and they dissipated into a white mist in the air. It is not until ten days later that the droplets of water fall on the sword case, maintaining a normal temperature.

When I opened the sword box, I was greeted by a sword embryo with an uncut blade about 1.6 meters long, 303 meters wide, and 0.2 meters thick. The sword embryo is dark black as a whole, but it is covered with dark red spots like teardrops, and at the lattice of the hilt, two convex lines like a dragon, one black and one white, form a small Tai Chi pattern.

Mo Han grasped the hilt of the sword with both hands and lifted the sword embryo from the sword box with great difficulty. Mo Han didn't know how many things he could lift at most with his current strength, but the weight of this sword embryo would definitely not be less than 100,000 kilograms. Mo Han only raised it for less than a second, and his two arms were already flushed, unable to bear the weight of the sword embryo.

Let go, let go. With a bang, the heavy sword plunged directly into the ground, and Qi Gen did not enter.

Mo Han sat on the ground, gasping for breath, his hands slapping each other's arms, relaxing the muscles in his arms.

The heavy sword has a spirit, and the spirit comes from the sword.

The dark black sword embryo that had sunk into the ground suddenly trembled, and flew upside down from the ground, landing itself where the flames were placed under the crucible.

The reincarnation flame flew out of Mo Han's palm uncontrollably and fell into the metallurgical platform.

Flames burst out and burned in the metallurgical table.

The dark black sword embryo rolled itself in the flames, allowing the reincarnation flame to cover every part of it.

The burn burned for seven hundred and forty-nine days, and when the last day came, the mountains at the poles were covered with dark clouds, lightning and thunder, as if the end of the world had come.

"Damnation!" Mo Han's eyes lit up instantly, followed by a helpless wry smile, "Old man Dugu, you are deceiving me, what I didn't take advantage of, what I didn't have the courage to survive the thunder tribulation of the Yuan Infant Period, this thunder tribulation has not yet arrived, but it has attracted the curse again, how can this be played."

"Fart, what do you kid know, this is not a curse, this is a catastrophe. The figure of the old man Dugu appeared beside Mo Han, looking solemnly at the thunder tribulation in mid-air, "Since ancient times, only when the best treasures have been refined, the thunder tribulation will appear. You kid blind cat has such good luck when you meet a dead mouse."

Mo Han didn't pay attention to the old man Dugu, he didn't know how powerful the weapon tribulation was, and he didn't know how many treasures had survived their weapon tribulation since ancient times, Mo Han just didn't want the heavy sword he had worked so hard to refine would be destroyed under the thunder tribulation: "Can I help it survive the thunder tribulation?"

"No, you can't. Old man Dugu seemed to understand what Mo Han was thinking, "Since ancient times, there have been many treasures that can survive the thunder tribulation, but there is only one treasure that can survive the thunder tribulation like this. This is the most powerful extreme thunder tribulation among the instrument tribulations, and all the instrument tribulations must be passed by themselves, if they are not survived by themselves, even if the thunder tribulation is passed, its grade will fall up several steps, and even become mortal."

The thunder tribulation in mid-air did not land immediately, but waited until the reincarnation flame was extinguished, turned into an inconspicuous stone and flew back into Mo Han's arms, and the sword embryo was completely formed, and the thunder tribulation roared down.

Mo Han seemed to be standing in another time and space, in front of him was a sea of thunder and lightning, and the dark black sword embryo was in the center of the sea of thunder and lightning, motionless.

The thunder and lightning in the sky centered on the sword embryo, swarmed and bombarded the sword embryo continuously.

Click, click.

Under the bombardment of lightning, fine cracks appeared on the surface of the sword embryo one after another, as if the sword embryo would collapse at any time.

Mo Han stood in place, squinting at the sword embryo in the center of the thunder and lightning, not sad or happy, and didn't seem to be worried at all.

"Aren't you worried that the sword embryo won't be able to withstand the thunder tribulation and will turn into ashes in the thunder tribulation? The old man Dugu looked at Mo Han with a calm face, and suddenly couldn't guess what Mo Han was thinking in his heart.

"If it is destroyed by the Thunderstorm, then it is not worthy of me, so what should I worry about?"

The sword embryo was already full of cracks, and under the gaze of Mo Han's gaze, it was shattered piece by piece. Before the old man Dugu could make a regretful voice, a strong light suddenly burst out from the sword embryo.

The black and white light blended together perfectly, turning gray, and wherever the gray went, the raging thunder and lightning seemed to meet a natural enemy and dissipated.

"No, the thunder and lightning did not disappear, but was absorbed by the sword embryo. Old man Dugu's face was full of shock, and he didn't know what kind of demonic heavy sword Mo Han had forged this time.

After a full hour, the thunder and lightning in mid-air completely disappeared, and a heavy sword with the same length, breadth, and thick gray flutter appeared in front of Mo Han.

At this time, the surface of the heavy sword was extremely smooth, there was nothing fancy, it looked ordinary, thrown on the street, no one would even pick it up, even the Tai Chi pattern on the hilt grid had disappeared, and the only thing left was the specks like teardrops.

Mo Han held his hands on the hilt of the sword: "Since you are refined by reincarnation flame, and the sword embryo also has the meaning of yin and yang, I will call you the 'Taiji Heavy Sword'!"

Heavy Sword trembled slightly, and seemed to be very satisfied with the name Mo Han had chosen for him.

Just as Mo Han was carefully observing the heavy sword, Mo Han's palm suddenly hurt, and an inconspicuous wound was cut by something, and blood flowed out along the wound and poured into the heavy sword.

Tai Chi heavy sword, the weapon that accompanied Mo Han's life, killed countless people, accompanied Mo Han through the mountain of corpses and the sea of blood, accompanied Mo Han through the bloody rain and bloody wind, and was turned into blood by others!

With Mo Han's current physique, an inconspicuous wound could recover in the blink of an eye, and it would not have any effect on him at all.

The Tai Chi heavy sword that had absorbed Mo Han's blood suddenly trembled sharply, as if it had its own soul, and as if nothing had changed. When the Tai Chi heavy sword calmed down, Mo Han found that the hands holding the Tai Chi heavy sword were much lighter, and he even felt that he didn't hold anything, but the Tai Chi heavy sword was a real existence.

The Tai Chi heavy sword without a blade gives people the feeling of being "blunt". But Mo Han, who was holding the Taiji heavy sword, felt that everything was just right with the Taiji heavy sword without a blade.

Mo Han picked up the Taiji heavy sword in his hand with both hands, and slashed towards the low mountain range not far away.

Rumble.

As soon as the Tai Chi heavy sword was swung, the wind it drove was painful in the ears, and when it landed on the mountain range, it felt that the ground was trembling, and the mountain range turned into a ruin in an instant, disappeared in front of the eyes, and fell deep into the ground.

Mo Han looked at the big pit in front of him dumbfounded, with a look of disbelief. It looks so inconspicuous, perhaps the Tai Chi heavy sword, which has no characteristics except for its heavy heel and hardness, is so lethal.

"Alright, boy, this is the best blade for you, but you'd better put it away in a crowded place, or you'll accidentally put it on the ground, and it will cause a big earthquake. The old man Dugu glanced at the Tai Chi heavy sword in Mo Han's hand, pursed his mouth, felt a little apprehensive in his heart, and turned around and returned to Mo Han's sea of knowledge.

Mo Han hadn't recovered from the powerful visual effects caused by the Tai Chi Heavy Sword, and he was wondering if if he used the Tai Chi Heavy Sword to give Nangong Glory or Beidou Qingyun a blow, would they turn into a piece of meat in shock.

"Oh, by the way, boy, it's best not to put your Tai Chi heavy sword directly into your storage ring, try it with a storage bag first, you will have an unexpected surprise!"

"Unexpected surprise?" Mo Han looked confused, what other surprise could I have if I put my blade in the storage bag? Could it be that the old man Dugu started to tease again?

Thinking about it, Mo Han still did what Old Man Dugu said. Take out a storage bag and place the Tai Chi heavy sword in it.

Before Mo Han could let go, there was a crisp sound from the storage bag, and a small crack appeared on the surface of the storage bag, and in the mouth of Mo Hanmu and others, the storage bag turned into a piece of fragments.

"Old man Dugu, your uncle, why didn't you tell the master earlier, the Tai Chi heavy sword will cause the storage bag to collapse, and there are still hundreds of yuan stones in the storage bag!"
