Only nearly a hundred weapons have been refined, and such refining experience is not rich at all, but can be said to be pitiful.

But Chu Jingtian still decided to upgrade the Purple Phantom Halberd.

For one, he had been here for a month and could not stay any longer.

Second, if he wanted to upgrade the Purple Phantom Halberd, he only needed to integrate that large piece of snake treasure into the Purple Phantom Halberd, which was much easier than refining a new heaven-level martial art weapon.

After paying attention, Chu Jingtian no longer hesitated, flipped his hand, took out the huge snake treasure the size of a round table, and threw it into the flames of the center of the earth.

He had to refine this snake treasure first to eliminate the impurities in it before he could merge it into the Purple Phantom Halberd.

However, after the serpent fell into the flames, it did not immediately begin to soften like the previous metal.

Its large weight means super high density, and the denser the item, the higher its hardness, and it is not so easy to burn it into a liquid-body.

However, Chu Jingtian had already expected this and was ready to persist for a long time.

As the first day passed, the huge snake treasure had finally softened a little.

On the third day, the snake began to soften overall.

On the seventh day, the snake treasure finally showed a hint of liquefaction.

On the tenth day, the snake treasure finally liquefied completely, turning into a large mass of flowing metal-liquid.

On the eleventh day, some black smoke began to come out of the liquid metal body, which was a sign that the impurities in the snake treasure had been refined.

And so on for nine days.

On the twentieth day, there was finally no more black rock in the molten metal.

At this time, the weight of this snake treasure was a full 4,000 catties less. In other words, in the past few days, a full 4,000 catties of impurities have been refined.

However, in order to keep improving, Chu Jingtian still put the metal liquid body on the flame and burned it, and he wanted to make sure that there were no impurities in it.

It burned for another two days, but the weight of the snake treasure did not decrease in the slightest.

Only at this time, Chu Jingcai nodded with satisfaction, and then took out the purple phantom halberd and threw it into the flames.

The material used in the Purple Phantom Halberd is not much worse than that of the Snake Treasure, and it has been tempered, and the hardness is even more amazing, so the melting process is also extremely slow.

On the twenty-fifth day, the purple phantom halberd finally showed some signs of softening.

......

On the fortieth day, the purple phantom halberd was completely liquefied.

On the forty-fifth day, there was no more black smoke coming out of the liquefied metal of the purple phantom halberd.

The Purple Phantom Halberd had already undergone a tempering, so the impurities contained in it were naturally much less. Moreover, this time it was also thanks to the geocentric flames, otherwise these impurities would not have been refined at all.

And the impurities were refined, and the weight of the purple phantom halberd was also reduced by more than a thousand catties.

On the forty-sixth day, Chu Jingtian moved his hands and merged the liquid body of the purple phantom halberd and the liquid body of the snake treasure.

And because it is both liquid-body, the fusion of the two is extremely smooth.

On the forty-seventh day, the two had become one. Now, even if Chu Jingtian wanted to separate the two, he couldn't do more.

However, Chu Jingtian was not in a hurry, but dragged it with his true yuan, and then used his spiritual power to make the liquid-body metal mass with a total weight of more than 70,000 jin constantly tumble above the flames.

This will make the two blend more evenly.

And so it passed another day.

On the forty-eighth day, Chu Shocking Heaven's spiritual power moved, and the huge liquid-body metal mass was instantly pressed into the shape of a purple phantom halberd.

However, at this time, the liquid-body metal purple phantom halberd looks twice as thick as the original purple phantom halberd, almost equivalent to the thickness of an adult's calf, and the length is still one zhang and two feet.

Then, he put the purple phantom halberd into the pool on the side.

The length of the pool was not enough to hold the Purple Phantom Halberd, so he put it twice in succession before it was completely cooled.

As a result, a purple phantom halberd with the thickness of an adult's calf and a length of one foot and two feet appeared.

Chu Jingtian put the rough embryo of the purple phantom halberd on top of the anvil, picked up the hammer on the side, and began to beat.

This hammer was specially smelted by Chu Jingtian in order to beat the purple phantom halberd, and the heaviest hammer here was only about 100 catties.

And if you want to beat the purple phantom halberd, that kind of weight is definitely not enough.

"Bell!"

The huge iron hammer weighing more than a thousand catties, under the effect of Chu Shocking's power of hundreds of thousands of catties, smashed fiercely on the purple phantom halberd.

The purple phantom halberd with a thick calf instantly dented a piece.

This is the reason why the speed of Chu Jingtian's refining weapon is so fast, hundreds of thousands of catties of power, no matter what it acts on, its effect will be extremely significant.

It was a whole day.

On the forty-ninth day, Chu Jingtian once again placed the Purple Phantom Halberd on top of the flames. He's going to keep burning red, and then hammering.

On the fiftieth day, the sound of the bell ringing again.

On the fifty-first day, he was again put on the stove and burned

......

And so on and so forth.

All the way to the sixtieth day.

"Bell!"

As the last metal pop sounded, Chu Jingtian smiled at the corner of his mouth, and put down the sledgehammer in his hand with satisfaction.

At this time, the purple phantom halberd had become only as thick as an egg, and it was several sizes smaller than when it was at the beginning.

And the most important thing is that after more than ten days of repeated calcination and beating, the purple phantom halberd at this time has become extremely tough.

Just now, Chu Jingtian took the hammer of more than 1,000 catties and used his strength of more than 500,000 catties to knock on the purple phantom halberd, but he failed to leave any mark on the purple phantom halberd.

It can be seen how tenacious the purple phantom halberd at this time has become.

And the reason why it is so tough is naturally because of the terrifying density, don't look at the volume of the purple phantom halberd at this time seems to have not changed much compared to before, but its weight has changed from more than 20,000 catties to 77,000 catties now.

With such a terrifying weight, it is no exaggeration to say that Chu Jingtian can kill one or two martial artists as long as he throws the purple phantom halberd out casually now.

Of course, along with the weight, there is also the level of the Purple Phantom Halberd.

Just based on the tenacity of the Purple Phantom Halberd to withstand the hammer blows of the super great force without leaving any traces, Chu Jingtian could judge that the level of the Purple Phantom Halberd had now reached at least the middle level of the Heaven Rank, which was a full two levels higher than the original Ground Rank Level.

Such a huge improvement was a surprise for Chu Jingtian, a half-hung refiner, he had never thought that there would be such a big improvement.

A little excitedly, he held the purple phantom halberd and danced a few times, feeling the current power, and then he put the purple phantom halberd away.

Then, he turned around and walked out of the Great Hall of Refining.

Counting the time, he's been here for more than two months, and it's time to leave.

Walking out of the refining hall, and exiting the auxiliary repair tower along the same path, Chu Jingtian returned to the secret realm.

At this time, there are no traces of people in the secret realm, and more than two months have been enough for those people in Tianxin City to sweep the entire secret realm, and those people are afraid that they have already left.

Immediately, Chu Jingtian also flew towards the entrance of the secret realm, the treasures here had been swept away, and there was no need for him to stay.

Leaving the secret realm, Chu Jingtian appeared in that huge valley.

Identifying the direction, just as he was about to fly towards Tianxin City, his movements were slammed, and then a smile appeared on the corner of his mouth.

In the next second, he dodged into the Heavenly Envy Tower.

Just now, he felt the vibration of the Void Gate, and someone wanted to use the Void Gate.

And the only Void Gate he had placed outside now was in Canglong Academy.

And when he left Canglong Academy, he had confessed that if Yemo returned to the academy, let him come to him through the Void Gate, there was no doubt that Yemo should be coming.

Calculating the time, it has been four months since he left Canglong, and it is time for Yemo to come.

As soon as his heart moved, his body flashed again, and he appeared directly on the fifth floor of the Heavenly Jealousy Tower.

Stepping to the main gate with special symbols, Chu Jingtian casually made two handprints and entered.

Immediately, a light flashed on the Void Gate, and a graceful figure, with a smile, appeared in front of Chu Jingtian, that familiar face and expression, who is it not Yemo?

"Coming?" Chu Jingtian asked lightly with a smile on his face. And it is this faint greeting, but it already contains everything.

"Hmm. Ye Mo nodded, and then said with some excitement: "This time, thanks to this Void Gate, otherwise I would have taken at least four or five months to come here from Canglong." ”

Canglong is close to a million miles away from Tianxin City, and it took twenty days for Chu Jingtian and Xiao Fei to cross the void at the beginning. If you only rely on night ink, then four or five months is already fast.

Chu Jingtian smiled slightly and nodded, this time, the Void Gate did play a great role.

Immediately, he pointed to the seven auxiliary doors beside him and said with a smile: "You take one of these seven doors with yourself, so that no matter where you are or how far apart you are, you can come to me at any time." ”

Hearing this, Yemo didn't shirk it, just took one casually and included it in his ring. Being able to be by Chu Jingtian's side at any time is extremely important to her.

Then, she smiled at Chu Jingtian, "Since you gave me a gift, then I will give you one too."

After the words fell, she turned over and took out a jade bottle and handed it to Chu Jingtian.

"What is this?" Chu Jingtian looked at the jade bottle in his hand with some curiosity.

Inside the jade bottle, the biggest possibility is to contain pills, and as an alchemist, he has never lacked pills.

"Just look at it. "Night Ink sold a pass. smiled: "But be careful when you open it, the things in there are very precious, and if you don't get it right, it will be wasted." ”

Hearing this, Chu Jingtian became more and more curious.

Immediately, he took the jade bottle to his eyes and carefully opened the cap.

Then, his face changed suddenly......
