Gray City is quite far away from Quyun City, and it may take a lot of time to return to Quyun City, and even if he returns to Quyun City, with his current ability, he may not have much impact.

Jin Tian finally decided to settle in the Gray City first, although this place is mixed with jade dragons, but it is also well-informed, maybe you can get news about the three punches here.

In the casting room, Jin Tian came to the center of the casting platform, and with a wave of his robe, a black black iron forging furnace appeared on the stage, and at the same time, a diamond-shaped cyan crystal appeared in Jin Tian's hand.

Jin Tian then took out several materials one after another and placed them neatly on the side of the forging furnace.

Jin Tian pondered slightly for a moment, his fingers flicked, and a wisp of Xuan Qi poured out from his fingertips and flowed towards the forging furnace.

The flames in the forge suddenly rose, and Jin Tian then threw a piece of metal shaped like an ice cube into the furnace, and also threw Qingjing into it.

After the strange metal came into contact with the flames in the forge, it suddenly emitted bursts of cold air, and as the flames continued to burn, the strange metal was slowly changing.

The icy white metal slowly changed color as the flames burned, starting from the outermost layer, and the layers of icy white gradually faded, replacing it with the fiery red of the metal.

When the icy white color fades completely, the metal is indistinguishable from the ordinary metal that has been burned red.

At this moment, the flames in the furnace suddenly swelled, and the flames suddenly rose more than six feet high, and the metal in the furnace gradually became soft.

It then becomes softer and softer, transitioning to a liquid state, and when the metal is completely liquid, a silvery liquid appears in the air.

Jin Tian waved his left hand, and several rays of Xuan Qi floated in the fire carrying the liquid matter and green crystal.

As if the blue crystal was unaffected in the fire, it was still the same, and even the color had not changed.

When Jin Tian saw Qingjing's state, he also secretly breathed a sigh of relief in his heart, and then controlled the two to melt.

When Qingjing encountered the liquid substance, the originally dim surface suddenly emitted a burst of cyan light, and the liquid substance seemed to be controlled, and it squirmed.

Then a group of clumps rushed towards the Qingjing, and after a few breaths, the liquid completely enveloped the Qingjing.

Then Jin Tian only felt a burst of cyan light gushing out through the liquid, and the light did not dim, but became more and more intense.

After a quarter of an hour, the blue crystal became like a small sun, but the little sun emitted a cyan light.

Looking at the Qingjing floating in the air, a feeling of vicissitudes of life poured out from the bottom of Jin Tian's heart, and Jin Tian couldn't help but become more and more curious, what secrets were in this Qingjing.

At this moment, Qingjing suddenly converged the light, and the casting room suddenly darkened.

Jin Tian looked at the liquid substance, at this moment, only a cyan crystal was left there, and the liquid substance had long disappeared.

Jin Tian didn't stop, and then threw the second piece of material into the flames.

A few hours later, another burst of cyan light poured out.

Then came the third piece......

After spending eighteen hours in the casting room, Jin Tiancai completely melted the material and integrated it into Qingjing, or "absorption".

In fact, there is no difficulty in the whole process, the only thing that is a little difficult is the requirement for the degree of filling of the caster's Xuan Qi, and Jin Tian is now a powerhouse of the Quadruple Qi Transformation Realm, which is naturally nothing to Jin Tian.

Just as Jin Tian was packing up his belongings and preparing to leave, he suddenly was stunned with some surprise.

Jin Tian found that his body seemed to have been tempered by fire, and the strength of his body had been comprehensively improved.

There was a faint cyan glow in Jin Tian's skin, and if he didn't look carefully, it would be difficult for others to notice it.

In addition, the Xuan Qi in Jin Tian's body also showed signs of overflowing, and he found that there was a completely different Xuan Qi in his body from before.

The Xuan Qi in his body is pale cyan, and this new Xuan Qi is cyan.

Jin Tian was also surprised to find that this Xuan Qi was more condensed and pure than the Xuan Qi in his body before, and what was even more terrifying was that the pale cyan Xuan Qi in his body, with the help of this new Xuan Qi, was constantly removing impurities, and the Xuan Qi accumulated before the transformation of the four heavy qi had shrunk by almost one-third.

If this were not the case, I am afraid that Jin Tian, with the support of this Xuan Qi, would directly jump several levels, instead of just reaching the peak of the current Quadruple Qi Transformation Realm.

After Jin Tian felt the changes in his body, his heart suddenly beat violently, with this Xuan Qi, wouldn't he have more Xuan Qi accumulated in his future cultivation.

Although it may be a little slower to progress, the benefits are enormous.

Just imagine, when two people face each other, one of them has a higher degree of Xuan Qi condensation than the other party, that is to say, if he uses the same level of combat skills, the power will be higher than that of the other party.

The final victory or defeat can be imagined.

As for the shortcomings in cultivation speed, there are many ways to make up for them, such as using magic crystals, or finding some genius earth treasures, and the worst can also take pills.

But there is no doubt that what you have cultivated is the most real.

And the Xuan Qi in Jin Tian's body was still floating, and it wasn't until half an hour later that it finally stabilized and stayed in the late stage of the Fourfold Qi Transition.

And all the Xuan Qi in Jin Tian's body at this moment had also turned cyan, and the degree of condensation and purity was just like the newly entered Xuan Qi.

When Jin Tian tried to run the Mixed Yuan Gong, he found that the spiritual power extracted from outside the body and into the body only turned into pale cyan Xuan Qi after being transformed into Xuan Qi, and when this Xuan Qi came into contact with the original Xuan Qi in his body.

There was a change, and the Xuan Qi shrank a part, and it turned cyan, and the shrunken part was exactly about one-third compared to the original.

Jin Tian casually struck out a palm, and with a bang, the wall in the casting room shook violently.

"Sure enough," Jin Tian found that the combat technique released through the cyan Xuan Qi was even more powerful.

After feeling the changes in his body, Jin Tian raised his eyebrows and glanced at Qingjing, it seems that what Uncle Silkworm said is not all right, after repairing Qingjing this time, he has brought himself such a big harvest.

This time, the shortage of Xuan Qi caused by the incomplete Mixed Yuan Gong has been improved. However, although the Mixed Yuan Gong is not perfect, the degree of condensation of the Xuan Qi cultivated is not comparable to ordinary exercises.

Jin Tian was naturally fearless when dealing with ordinary enemies, but when dealing with enemies who had practiced powerful exercises, the disadvantage of his own exercises would be revealed.

Jin Tian packed up his belongings with excitement, and finally glanced at the unchanged Qingjing in his palm, put it on, and left the casting room.
